FIELD OF THE INVENTION

The invention relates to a building development having a building arranged on a building development base. The building development base has a pontoon having at least one float for floating on a liquid and at least one pile mooring. The pile mooring extends along a pile mooring axis perpendicularly to the pontoon through a passthrough opening of the pontoon.

The invention furthermore relates to a building development base and a pile mooring of such a building development.

BACKGROUND

A building development of the generic type of floating houses is known from the prior art, where said floating houses are arranged on a body of water, especially a lake, the ocean, or a river. Such floating houses are translationally and rotationally retained in their respective position on the body of water by means of pile moorings.

For a realignment of the pontoon on the water surface, it is necessary in the known building developments to separate these from the pile mooring and/or the anchors and thus enable the translational movement as well as also the rotational movement of the pontoon on the water surface. This procedure is complex and time-consuming.

It is furthermore known that floating houses are configured in such a way that they can float upward or downward relative to the pile mooring along the pile mooring axis along with a surface level of the water along a displacement area, especially with a high water or low water level, so that at least one side of the pontoon always projects out of the water. The building development can thus adapt to changing surface levels of the water. This allows the use of water surfaces as building development surfaces without an expensive draining of the bodies of water and flood protection measures.

In one aspect, it is disadvantageous of the known houses, especially houses floating on pile moorings, that they present a large contact surface for wind gusts and/or whirling objects during a storm. Due to the wind-induced forces, great forces additionally act on the pile moorings and can cause damage to the pile mooring and/or the pontoon.

It can additionally be disadvantageous, in particular when resource-consuming applications are arranged in buildings, such as, for example, a washbasin or a wall outlet, that the corresponding supply lines must be installed by a supplier in the building development base. As an alternative to this, there are also known self-sufficiency concepts, involving, for example, wind and/or solar energy and/or desalinization systems and/or water reservoirs and/or sewage treatment systems. The wastewater produced by them is often collected in tanks which must be regularly emptied.

In order to connect the known building developments to an external supplier, it is known that they can be connected to at least one supply line running essentially parallel to the water surface, frequently a flexible cable and/or a flexible tube. The supply lines often extend over long distances, so that they are exposed to the weather and/or water and thus age faster as a result of the movements caused by the varying surface levels of the water. From an esthetic point of view, these lines are also not visually appealing. In addition, the known supply lines can be seen from the outside and are relatively easy to access, particularly for unauthorized interference by third parties.

The supply lines of known building developments can furthermore be configured with a tolerance in such a way that they can compensate for a displacement during an axial displacement of the pontoon along the pile mooring axis, for example, during high water. This occurs for the most part in that a flexible line, especially a loose cable, has a length adapted to the greatest displacement path, whereby the line, with a neutral positioning within the displacement path due to its dimensioning, requires a larger installation space and is often loosely guided.

Despite the known disadvantages, floating housing concepts have the advantage that due in particular to the floating arrangement of the pontoon on the liquid, seismic vibrations are damped, for example during earthquakes. Floating houses also have the advantage compared to classical foundation constructions on solid ground that they can float in the event of a flood, and the buildings are less prone to water ingress.

Furthermore, with regard to rotation and translation, classical buildings and floating houses are tied a certain place: classical building due to their foundations, and floating structures due to their pile moorings, so that a building, in particular, is always arranged facing in one direction, and the sun shines on the building from different directions throughout the day. It is particularly disadvantageous for the occupants that they must adapt their use of spaces in the building to the height of the sun; for example, it is not possible, given the room layout and room size, to enjoy a dawn and a sunset from the same room. Furthermore, the solar panels of a photovoltaic system are usually aligned, at least to some extent, in one direction. With known buildings, the position of the sun, which changes relative to the building, reduces the efficiency of the solar panels. It can furthermore be disadvantageous with known buildings that, depending on the room layout of the building, inside spaces are not shielded from the view of others or from direct sunlight, and that the façade of the building which sustains gusts of wind during a storm also cannot be changed, so that, for example, the wind and objects that are picked up and carried by the wind are blown against a glass front of the building, which is more vulnerable than an adjacent walled façade.

SUMMARY

It is an object of the invention to make available a building development which avoids the problems associated with positioning or alignment that are known from the prior art and in particular provide protection against unauthorized interference by third parties and/or environmental influences in particular, especially environmental catastrophes.

The object is inventively achieved by means of the features of embodiments described herein. Precise solar radiation and optimized light incidence on the building development are made possible in that the passthrough opening is configured in the center of the pontoon, and the pontoon is manually and motorically rotationally movably mounted around the pile mooring which extends through the passthrough opening, wherein the pontoon can be aligned and positioned, in particular by 360° around the pile mooring axis, wherein the pile mooring projects into a receiving chamber through the passthrough opening of the pontoon and through a first breakthrough in a bottom of the receiving chamber arranged above the passthrough opening.

The rotation of the pontoon around the pile mooring, for example, during the summer, also makes it possible, if required, to turn one side of the building away from too intense solar radiation against windows/glass surfaces. In the winter months, the reverse rotation around the pile mooring makes it possible to direct the heat of the sun against a selected side of the building.

With regard to comfort, it is additionally possible to decide at all times which view of the surroundings will be given to users, residents, and/or guests in the building, as well as choosing the view of or into the building that will be allowed to those outside it.

The building can likewise be optimally positioned for protection against storms; the building can, in particular, be positioned in such a way that there is an especially good flow of air around the building and/or that an especially robust façade of the building faces the direction from which the wind is blowing.

The object of the invention is furthermore achieved by means of the features of additional features described herein. The building development base can be especially advantageously arranged independently of natural bodies of water in that the building development base has a basin filled with liquid, wherein the pontoon is arranged floating on the liquid in the basin, and wherein the pile mooring extends from a bottom of the basin along the pile mooring axis. The building development base has an advantageous damping effect, especially in areas prone to earthquakes. A building development base of this kind can accordingly be used as a foundation of a building and offers an alternative to the known concrete foundations. The basin in particular serves as a buffer against the primary energy of an earthquake; constructed in a clearly predefined sand/gravel bed, it offers fewer static contact surfaces. Thus only a low seismic magnitude of ultimately secondary energy acts on the building arranged on the pontoon, or on the building development base.

The rotationally movable pontoon with a pile mooring arranged in the center of the pontoon can be suitably arranged on the liquid located in the basin.

The rotationally movable pontoon can be effectively aligned and positioned so as to rotate, preferably by 360°, around the pile mooring axis by means of a motor that is immovable relative to the pontoon. A gearing is preferably configured and arranged in such a way that the force of the motor can act on a load-application element of the pile mooring. An electric motor, particularly one that is digitally controlled, is preferably used. Particularly advantageously, the digital control enables an automated positioning which is dependent, for example, on the time, position of the sun, or the room temperature of a building that may be arranged on the building development base.

According to one variant of the invention, at least one connection means for connecting at least one supply line for a connection system of the building is arranged in the receiving chamber, wherein the pile mooring is configured as a hollow body and has at least one supply channel; and at least one supply line of the connection system is guided through the supply channel, which is connectable to the connection means in the receiving chamber. The supply line is advantageously protected from external influences, and no additional installation space is required, which could create obstacles. The connection system can, in particular, be a water and/or wastewater and/or electric power and/or telecommunications system.

The supply line can furthermore be arranged underground and can, in particular, be installed in the building by a utility provider through the foundation of the pile mooring and in that way be invisible from the outside, so that unauthorized interference by third parties is made more difficult. In this sense as well, the visual appearance of the building is not disadvantageously affected, and the connection system is protected from environmental influences.

In order to maintain the rotational mobility, the supply line is configured in particular in such a way that it can compensate for a rotation of the pontoon around the pile mooring, in particular by 360°, for example by at least one connection means is configured as a mechanical latch contact and/or a loop contact and/or a ball-bearing mounted plug-in contact for the electrical lines and/or a pivotable coupling and/or a rotatable high temperature pipe connection for the water lines and/or a pipe-to-pipe connection running coaxially to the pile mooring axis in order to simultaneously conduct a wastewater flow and a freshwater flow.

A connection means is preferably configured as a loop contact with a current collector fixed with respect to the pontoon and a slip ring rotationally fixedly arranged on the pile mooring. Metal rails, in particular five metal rails, are suitably circulatingly arranged around the slip ring, wherein the current collector can contact the metal rails within an angular section of 360° around the pile mooring axis.

According to an advantageous embodiment, intermediate reservoirs, in particular a freshwater reservoir and/or a wastewater reservoir, can be arranged in the pontoon and/or in the building. The freshwater reservoir and/or wastewater reservoir consists in particular of several, in particular four, circumferentially interconnected tanks, preferably plastic tanks. In order to fill and empty the intermediate reservoir, the pontoon is aligned in a supply position relative to the pile mooring. In the supply position, the intermediate reservoirs can be manually or automatically connected to the supply lines arranged in the pile mooring, in particular by means of a motorized rail and a bayonet closure.

The liquid in the basin, in particular, at least in part, contains additives, wherein the additives preferably lower the freezing point of the water. The risk of frost damage in particular is reduced. In this way, the erection and use of a building development with a basin is also possible or is also advantageously facilitated in locations prone to freezing. Additionally, or alternatively, the liquid can also contain additives for purifying liquid and/or for preventing the growth of algae.

The basin is advantageously provided with an integrated inlet and outlet, preferably supported by pumps. The inlet and outlet makes possible especially that a surface level of the liquid in the basin can be variably selected and readjusted. The variable level has the advantage that the pontoon together with the building can be lowered into or lifted out of the basin. This provides the possibility of adjusting the building development to a total load on the building development base, similarly as with a level regulation system, in that a predetermined distance between the pontoon and the bottom of the basin is maintained. In particular, the draft of the pontoon relative to the liquid surface is not influenced by the surface level of the liquid. Beside the advantage for comfort, the building development can also be adapted to the user with regard to accessibility. In addition, or as an alternative, the inlet and outlet also enable the purification and/or heating and/or replacement of the liquid, also, in particular, without influencing the surface level of the liquid.

The pontoon is configured, in particular by means of the variable surface level of the liquid, so as to be axially displaceable with respect to the pile mooring along the pile mooring axis within a displacement range. The building and/or the building development base has suitable connection means for connecting at least one supply line for a connection system of the building. As protection from outside interference, the supply line preferably passes, as previously described, through the supply channel of the pile mooring. The supply line is advantageously configured such that it can compensate for an axial displacement of the pontoon relative to the pile mooring along the pile mooring axis. This can be achieved, for example, in that at least one supply line is configured as a telescoping line.

The displacement area of the pile mooring is suitably configured in the direction of the liquid in such a way that in the low-lying position of the pontoon, the building is arranged within the basin over part of its height. The advantage herein is that through the immersion of the building, protection from intense storms, such as hurricanes or tornados, is achieved due to a reduction of the surface area of the building that is exposed to the wind.

The basin is preferably configured with an integrated means of overflow protection especially in rainy areas. This can be suitably implemented by means of floating valves. In this way, a maximum surface level for the liquid in the basin can be effectively set in a particularly easy and error-resistant manner.

The building preferably has a second breakthrough in a ceiling of the receiving chamber or in the roof of the building in the area above the passthrough opening, so that an overhang of the pile mooring can be arranged in the second breakthrough, especially in the low-lying position of the pontoon.

In a normal position of the pontoon relative to the pile mooring, the pile mooring preferably projects from the breakthrough into the receiving chamber with an overhang with respect to the bottom of the receiving chamber. The displacement area extends at least in part over the overhang so that the pontoon can float within the displacement area, at least from the normal position into an elevated position.

The normal position thereby corresponds in particular to a positioning of the pontoon relative to the pile mooring in which the pontoon is essentially arranged, that is in relation to the other positions, for most of the time. The displacement area extends, for example, between a normal position in which the pontoon is properly arranged and the elevated position, for example, with high water or a flood, when the pontoon floats to an exceptional height.

The size of the overhang thereby determines the maximum upward floatation height and can, in particular, be adapted to the existing rules for storm forecasts and disaster warnings.

The displacement area of the pile mooring is especially configured in such a way that the pontoon can sink, starting from the normal position of the pontoon relative to the pile mooring in the direction of the liquid into a low-lying position within the displacement range, for example, with low tide or a dropping liquid level.

The second breakthrough is advantageously provided with a manual or automatic lock for protection against weather conditions, which seals the second breakthrough if the pile mooring is not arranged in the second breakthrough.

The pontoon is advantageously provided with a manual and/or automated, in particular an hydraulic level regulation system. The level regulation system essentially aligns the surface of the pontoon that faces toward the building within a horizontal plane with respect to the surface of a liquid by means of displaceable load entries in floats. The level regulation system is particularly advantageously configured such that it can constantly monitor and preferably constantly readjust the alignment of the pontoon. The level regulation system can compensate for weight differences, depending on the design of the building development, or the weight distribution over the building development base. The level regulation system is preferably also provided with an alarm unit which sends a signal to the user and pinpoints the location of the critical weight difference in the event a weight difference can no longer be compensated for. The user who uses the alarm system is thus enabled to locate and adapt the weight distribution over the building development base.

The pontoon is especially provided with one or several floats, wherein preferably one float has individual chambers which, depending on the weight distribution, can be statically or dynamically adapted to the weight difference by the level regulation system. Individual chambers or the entire floating installation can be filled, for example, with the liquid on which they float, or the liquid can be redistributed from the chambers or the floats into other chambers or floats.

As an alternative or in addition, the level regulation system can be improved or deployed by means of fluidic intermediate reservoirs arranged circumferentially in the pontoon. The liquids in the tanks of the freshwater reservoir or the wastewater reservoir can suitably be systematically recirculated with the aid of a pump. The weight distribution of the pontoon can in this way be advantageously dynamically adjusted to variable loads.

The building can be suitably supplemented with a fire-resistant roof construction. This is advantageous in the case of buildings that are at risk from wildfires, particularly in regions with a climatic tendency to drought and/or endemic drought.

The submersible building development base, in combination with a fire-resistant roof area of the building, advantageously ensures protection of the building in case of fire in the immediate area. To this end, the building is suitably provided with a water-tight, tub-like, flat roof construction, which comprises a water basin. Using the pumping system, the water basin can be flooded, in particular in the event of fire in the immediate surroundings, with the liquid that is temporarily no longer needed, suitably the liquid in the basin.

Particularly advantageous is a circumferential roof overhang, which, when the building is lowered, slots flush with the ground into a channel that runs around the upper basin edge, in particular with a flute. The channel is flooded, if necessary, with a liquid, for example water, which enables cooling and provides protection from invasive flue gases. Advantageously, with this preferred embodiment, when the building or the building development base is lowered, no physical resistance stands in the path of the fire, and as a result, even a wildfire driven by strong winds, for example a firestorm, quickly passes over the building development without finding local fuel for the flames.

Fire-resistant materials have proven advantageous for the flat roof construction and/or roof overhang. The flat roof construction and/or roof overhang are formed, in particular, from alloyed and/or unalloyed steel and/or ceramic composites.

The results of small-scale trials with a simulated fire source showed a moderate evaporation of the surface water and simultaneous heating to approx. 35° C.

The roof building development suitably has a rooftop garden with low lichens and/or moss and/or grass or can be planted with greenery. A plant substrate, which consists at least in part of native soil and is enriched with perlite and expanded clay, in particular for weight reduction, is preferably used for the greenery. All of the aforementioned embodiments can be advantageously configured in modular form. Thus, even a relocation of the building development across land or water can be realized with the aid of prefabricated components ranging from a multipart pontoon to displaceable wall elements and a standardized basin. A modular design also enables an individual adaptation of the building to the respective environmental conditions and preferences.

The object of the invention is also achieved with a building development base, wherein the base of building development has a pontoon on which a building development, in particular a building, can be arranged. According to the invention, the building development base for achieving the task corresponds to one of the aforementioned embodiments.

The object of the invention is based is furthermore attained by means of a pile mooring having the features described herein, which has the features of one of the aforementioned embodiments of the pile mooring according to the invention.

DETAILED DESCRIPTION OF EXEMPLARY EMBODUMENTS OF THE INVENTION

The same parts are always provided with the same reference numerals in the various figures of the drawing.

It is claimed with regard to the following description that the invention is not limited to the exemplary embodiments and consequently not to all or several of the features of the described combinations of features, but rather that each individual partial feature of the/each exemplary embodiment can as such be of importance to the object of the invention, also in isolation from all other partial features described in connection therewith, as well as in combination with any features of another exemplary embodiment.

FIGS.1and6to9show the building development1having a building4arranged on a building development base2.

The building development base2has a pontoon8having at least one float6for floating on a liquid and at least one pile mooring10. The building development1according toFIG.1has in particular only one pile mooring10. The pontoon8, in particular, as shown inFIG.3in plan view, is shown as having a round shape or a rectangular shape as shown inFIGS.10and11. InFIG.2the float6of the pontoon8additionally shown. Here the building4is arranged on a surface12of the pontoon8that faces toward the building4.

According to an embodiment that is not depicted, a pontoon8with more than one float6preferably has a supporting framework in which the float6can be stably arranged. The supporting framework, which holds together the individual floats6, can be suitably replaced by connections of the individual floats6to each other. As a result, the floats6are connected to each other especially in a materially bonded or force-fitting or force-and-form-fitting manner, preferably screwed, glued, or welded.

The pontoon8or the float6can be advantageously made of metal, especially steel or aluminum, fiberglass, or carbon. They can also be made from a combination of materials, for example reinforced concrete, in alternative embodiments of the pontoon8or the float.

The pile mooring10extends along a pile mooring axis X perpendicularly to the pontoon8through a passthrough opening14of the pontoon8. Exemplary embodiments of the pile mooring10are depicted inFIGS.4,5, and12. The pontoon8together with the building4can float up or down with the rise or fall of the liquid level or the surface of a liquid and can adapt in this way to environmental conditions or the user's wishes for protection and comfort.

The liquid can, in particular, be a naturally-occurring liquid in the form of water in a lake, ocean, river, or in a man-made pond, basin24, or other collection body. The pile mooring10is thereby fixedly connected to a foundation on a bottom in the liquid, especially the bottom of a lake, ocean, river, a bottom26of the basin24, a pond bottom, et cetera.

According to the invention, the passthrough opening14is configured centrally in the pontoon8, as depicted inFIGS.1to5, and the pontoon8is movably mounted, rotating manually or with a motor, around the pile mooring10which extends through the passthrough opening14. The pontoon8can be aligned and positioned in particular by 360° around the pile mooring axis X, wherein the pile mooring10projects into the receiving chamber through the passthrough opening14of the pontoon8and through a first breakthrough16in a bottom of a receiving chamber arranged above the passthrough opening14. The centrally arranged pile mooring10has, as a result, the advantage that an expensive mooring is not necessary in order to almost fully prevent a translational movement of the pontoon8over the liquid surface. A selected rotational movement of the pontoon8with respect to the pile mooring10is blocked with a mooring between the pontoon8and an immovable object, for example a shore or pier, or by means of a blockage between the pontoon8and the pile mooring10.

Regarding the requirements of the user of this building development1, it is an advantage when aligning the sun, for example, in order to focus sunlight on a living space, or when providing a pier for mooring a boat, if the pontoon8or the building4arranged on the pontoon8can be rotationally aligned, particularly by 360°, around the pile mooring10.

Furthermore, when using a photovoltaic system, in particular on a roof18and/or on a façade20of the building4, the rotation of the pontoon8enables a constant alignment of the photosensor cells which is adapted to the position of the sun and which preferably continuously self-corrects. The building development's foundation2is also able to rotate with the movement of the sun by means of a manual, or especially an automated alignment of the pontoon8, thereby enabling a significantly optimized light incidence on the photosensor cells and a higher efficiency of the light and energy yield respectively.

The rotation of the pontoon8furthermore makes it possible to turn the building4away from possibly excessively intense solar radiation on windows/glass surfaces. The rotation around the pile mooring10likewise makes it possible to reverse the alignment toward the direct incidence of the heat of the sun.

With regard to the comfort, it is, in addition, always possible to decide what view of the environment will be given to the users, inhabitants, and/or guests of the building4. Or to determine what view of or respectively into the building4will be permitted to those on the outside.

The pontoon8can be axially displaced, in particular inside the displacement range22along the pile mooring axis X relative to the pile mooring10. A changing level of the liquid, for example due to wave action, flood, or a low surface level of the liquid can, for example, be especially compensated for in this way.

In another embodiment according to the invention, as a supplement or alternative to the rotating house with a central pile mooring10, the building development base2has a basin24filled with liquid, wherein the pontoon8is arranged floating on the liquid in the basin24. Along the pile mooring axis X, the pile mooring10extends from a bottom26of the basin24, wherein the pile mooring10is immovably connected to the basin24. Embodiments of this building development1with a building development base2having the basin24are depicted inFIGS.1and6to9.

InFIGS.1,2, and12, a central pile mooring10is connected to the bottom26of the basin24, and inFIGS.6to8, two or three pile moorings are connected to the bottom26of the basin24. In this embodiment, the building development1can be particularly advantageously erected without any restrictions regarding location. Accordingly, such a building development base2can be used as a foundation of the building4.

The building development base2with a basin24furthermore has an advantageous damping effect in contrast to classical concrete foundations, especially in areas prone to earthquakes. This shock absorption is achieved by means of the advantageous interaction between the basin24filled with liquid and the pontoon8floating on the liquid. The basin24serves especially as a buffer for the primary energy generated during an earthquake so as to offer less static contact surface especially when erected in a clearly predefined sand/gravel bed. Only a low seismic magnitude of ultimately secondary energy thus acts on the building4arranged on the pontoon8or on the building development base2.

The pontoons8depicted inFIGS.3,10, and11are advantageously configured as a plate with a flat side facing in the direction of the liquid. Especially the embodiment of the pontoon8according to the embodiment inFIG.3, which is rotatable about the central pile mooring10, is as a result configured as a circular plate, so that a gap28between the pontoon8and a wall30of the basin24can be kept as small as possible and the rotation is still possible.

FIG.10shows an advantageous embodiment of the pontoon8, according to which the latter is configured as a rectangular plate. The rectangular shape in particular of the pontoon8when there is a rectangular building4on the building development base2enables a better weight distribution and surface utilization.FIG.11shows an embodiment, according to which the pontoon8is configured as an L-shaped plate and is particularly advantageous for L-shaped building developments.

The pontoon8of the building development base2depicted inFIGS.1to3and12can be aligned and positioned rotationally around the pile mooring axis X by means of a motor32, not depicted inFIG.12, which is configured as immovable with respect to the pontoon8. Here, a gearing is suitably configured and arranged in such a way that the force of the motor32can act on a force application element34of the pile mooring10. Part of the transmission and the force application element34of the pile mooring10are shown as an example inFIGS.4and5.

The motor32is configured particularly advantageously as an electric motor, one variant of which can be digitally controlled.FIG.5shows an arrangement variant of the motor32, the gearing, and the force application element34. The motor32is configured in particular in such a way that the pontoon8can be aligned and positioned by 360° around the pile mooring axis X.

Particularly advantageously, the digital control enables an automated positioning, dependent, for example, on the time of day, the position of the sun, or the room temperature of the building4arranged on the building development base2.

The motor32is suitably provided with a braking and/or blocking function. This function makes it possible to limit or prevent a rotation of the pontoon8around the pile mooring axis X, so that in particular no further mooring or blockage element is needed to retain a selected alignment of the pontoon8.

As shown inFIG.5, the motor32which is immovably arranged on the pontoon8has a specific drive height36with respect to the bottom of the receiving chamber. The force of the motor32is transmitted to the force application element34of the pile mooring10at this drive height36. A support38, with which the drive height36is adjusted, is arranged between the pontoon8and the motor32in the shown exemplary embodiment. As depicted inFIGS.4and5, the force application element34advantageously extends axially over a drive section40of the pile mooring10. With a displacement of the pontoon8within the displacement range22toward the pile mooring the drive section40is displaced in the same proportion relative to the drive height36. The motor32, the gearing, and the force application element34are in particular configured in such a way that with a displacement of the pontoon8relative to the pile mooring10axially to the pile mooring axis X, the force of the motor can act on the force application element34for as long as the drive height36is located within a range of the drive section40.

In the embodiment depicted inFIG.5, the gearing is configured as a gear transmission. Here it is advantageous that the force of a driven gear wheel42connected to the motor32can act in particular by means of the force application element34on a drivable gear wheel44which is rotationally fixed on the pile mooring10, whereby the drivable gear wheel44is displaceably mounted axially to the pile mooring axis X within the displacement range22.

According to a preferred embodiment, which is not depicted, the gearing is configured as a bevel gear transmission. It is advantageous if a bevel gear connected to the motor32can transmit the force to a crown wheel that is at least rotationally fixed on the pile mooring10. According to the embodiment depicted inFIG.5, the crown wheel with force application elements34that extend axially to the pile mooring axis X is preferably rotationally fixed on the pile mooring10and is in particular displaceably mounted axially to the pile mooring axis X within the displacement range22.

In the embodiment depicted inFIGS.1to5, the displacement range22is configured, for example, over 1 m, so that low waves can be advantageously compensated for. With an arrangement of the building development base2in the basin24, a smaller displacement range22is also possible. With a building development1that is mounted to movably rotate around the pile mooring10, the displacement range22can also be configured as greater than 1 m.

Arranged in the receiving chamber in particular are connection means for connecting at least one supply line46for a connection system of the building4. The pile mooring10is suitably configured at the same time as a hollow body, as shown as an example inFIGS.4and12and has at least one supply channel48. At least one supply line46of the connection system, which is configured for connecting to the connection means in the receiving chamber, is preferably guided through the supply channel48. The connection system relates especially to the water and/or wastewater and/or electric power and/or telecommunications systems. At least one supply line46can suitably also be configured as a hollow pipe and be guided through the pile mooring10so that a connection system can be retrofitted.

In particular, with the connection means and the supply lines46guided through the supply channel48, no additional installation space, which would represent an obstacle, is required. A particularly preferred embodiment is depicted in particular inFIG.1, according to which the connection system is guided through a ground section50and is thus not visually recognizable or manipulable, or routed in an interfering manner. In this sense, visual appearance is not disadvantageously affected by the connection system, and the connection system is protected against environmental conditions.

The supply line46is preferably configured in such a way that it can compensate for an axial displacement of the pontoon8relative to the pile mooring10along the pile mooring axis X. The supply line46can preferably be configured in such a way that it can compensate, for example, for a displacement of the pontoon8within the displacement range22depicted inFIG.4.

Especially in the embodiment of the building development base2according toFIGS.1to3and12with the pontoon8rotatable around the pile mooring10, the supply line46is particularly configured in such a way that it can compensate for a rotation of the pontoon8around the pile mooring axis X, specifically by 360°. For this embodiment at least one connection means is configured as a mechanical latch contact and/or a sliding contact and/or a ball-bearing mounted plug-in contact for the electrical lines and/or pivotable coupling and/or rotatable high temperature pipe connection for the water lines. In particular, at least one supply line46is configured as a pipe-to-pipe connection running coaxially to the pile mooring axis X in order to simultaneously guide a wastewater flow and a freshwater flow.

FIG.12shows as an example a particularly advantageous embodiment of the building development base2with a pontoon8that is rotatable around the pile mooring axis X. As depicted, a connection means is preferably configured as a sliding contact having a current collector90fixed to the pontoon8and a slip ring86configured so as to be at least rotationally fixedly arranged on the pile mooring10. The slip ring86in particular is connected to a supply line46configured as a power line84guided through the pile mooring10for connection to the communal power grid. Metal rails88, in particular five metal rails88, are suitably arranged circumferentially around the slip ring86, wherein the current collector90can contact the metal rails within an angular section of 360° around the pile mooring axis X. The current collector90is especially connected to a conductor rail94, which is guided within a current conductor92up to and into an area of the slip ring86, so that the current collector90can contact the metal rails88of the slip ring86as shown. A preferred arrangement, according to which the current conductor92runs toward the ceiling70and is secured by means of a mount96is further depicted inFIG.12. The supply system is arranged in this way in the receiving chamber in an advantageous space-saving manner.

Another supply device suitable for a pontoon that can be displaced toward the pile mooring axis and/or can be rotated about the pile mooring axis provides for at least one intermediate reservoir to be arranged in the building4or in the pontoon8, wherein the intermediate reservoir has at least one connection means which is not continuously connected to the supply line46. Intermediate reservoirs can in particular be current collectors or wastewater and freshwater reservoirs. According to an advantageous embodiment, the freshwater reservoir and/or the wastewater reservoir can in particular consist of several, specifically four, circumferentially arranged and preferably fluidically interconnected tanks, in particular plastic tanks.

The pontoon8can be suitably transferred into a supply position, as shown inFIG.12, in which the connection means can be connected to the supply line46, so that the intermediate reservoir can be filled or emptied. In the supply position, the intermediate reservoir can be manually or automatically connected to the supply line46which is arranged in the pile mooring10in particular by means of a motor splint and/or a bayonet closure. As shown inFIG.12, in the supply position, the wastewater line82is connected to the supply line46for wastewater. At the same time, the intermediate reservoir is configured such that the building development1can be supplied from the intermediate reservoir via the respective connection system for a specific period of time, at least until the supply position is reached again.

A line carrying a liquid, in particular the freshwater line80and/or the wastewater line82, can be configured as a high-strength flexible tube in order to compensate for an axial and/or rotational displacement of the pontoon8relative to the pile mooring10along the pile mooring axis X. Such a high-strength flexible tube is preferably used for a fluid bridging from the supply line46in the pile mooring10to a pipe system, especially to the intermediate reservoir installed in the pontoon8or in the building4.

The intermediate reservoir can also advantageous be a current collector, for example an accumulator. In the supply position, it can be charged, for example, via a fuel cell and/or a wind turbine and/or a photovoltaic system and/or the communal power grid, whereby other techniques are also possible. The current collector can suitably also be charged by means of an induction system. The pontoon8preferably has a coil which is used by an antagonistic coil to inductively charge the current collector via a magnetic field that is within a functional range, in particular in an edge area of the building development base2. The functional range for inductively charging the current collector is accordingly ensured, at least in the supply position.

According to a variant of the intermediate reservoir, the pontoon8preferably has components that function as solid heat reservoirs. In addition or alternatively, a latent heat reservoir, especially a paraffin or salt hydrate, is also suitable for storing and efficiently using heat.

The supply position can preferably be randomly selected, for example, it can be the position in which the pontoon8is predominantly arranged.

The supply position can in particular be a specific rotational alignment of the pontoon8; this embodiment is particularly advantageous with a pontoon8moving rotationally around the pile mooring10like that of the embodiment ofFIGS.1and12. In this way, rotational connection means or supply lines46can be particularly advantageously dispensed with.FIG.12schematically depicts how the wastewater line82, which is connected to a wastewater reservoir (which is not shown) inside the building4and/or the pontoon8, is connected to the supply line46for wastewater in the supply position.

The supply position with rotationally determined pontoons8, like the embodiment inFIGS.6to9, can suitably be a specific height measured axially to the pile mooring axis X between the pontoon8and the bottom26of the basin24.

Particularly advantageously, the supply position can be activated automatically, for example, during the night, so that filling or emptying the intermediate reservoir can ideally be implemented without conflicts and with the least disruption for the residents of the building4.

Advantageously for ecological and economic use of the building development1and/or the building development base2, the building development1or the building development base2has at least one treatment plant, particularly for graywater and/or rainwater. Graywater can be suitably recycled at the same time by using photocatalytic ceramic foams and suitably collected in an intermediate reservoir. Rainwater can likewise be treated for the water supply and/or stored temporarily in intermediate reservoirs. The liquid on which the pontoon8floats. provided it consists predominantly of water, can also be processed for further use by employing suitable recycling methods.

In the embodiments depicted inFIGS.1and6to9the pile mooring10can be configured in particular as a steel pipe wherein, as an alternative to the round pile moorings depicted inFIGS.4and5, the pile mooring10can also be configured, in an embodiment which is not depicted, as having a rectangular profile.

In order to ensure the continuing applicability of the building development base2with a basin24in many locations, the liquid is on occasion provided with additives. The additives preferably prevent the growth of algae and/or lower the freezing point of the water. The addition of additives which lower the freezing point is advantageous in order to prevent damage due to frost, particularly in locations with temporary or constant temperatures near or below the freezing point. A building development base2and the concept of a floating building as residential housing can thus be advantageously implemented independently of an existing body of water. The building development base2with a basin24is therefore an alternative to classic buildings on foundations at the same time as it has the advantages of the floating arrangement, especially the earthquake protection.

As depicted, especially inFIGS.3,10, and11, the building development base2has a circumferentially configured gap28between the pontoon8or the floats6and a wall30of the basin24. The gap28is suitably kept as small as possible, while the gap28is configured in particular within a range of 1000 cm to 10 cm, preferably within a range of 100 cm to 15 cm, advantageously within the range of 40 to 20 cm. The gap28is suitably adapted to the possible translational movement freedom of the pontoon8across the liquid surface, which results especially from the play between the pile mooring10and the passthrough opening14.

In another aspect, the gap28between the wall30of the basin24and the pontoon8. as well as the distance between the passthrough opening14and the pile mooring10, are configured in such a way that an adequate absorption of short and long geological shockwaves or seismic waves is possible, so that earthquake protection is provided.

The basin24is suitably provided with an integrated, in particular pump-supported inlet and outlet52, as depicted inFIGS.1and6to9. As an alternative or additionally, the liquid is conveyed within a fluidic circuit by means of the inlet and outlet52in particular for purposes of purification and/or temperature control.

The inlet and outlet52are especially configured so that the surface level of the liquid in the basin24can be variably selected and readjusted. The pontoon8is preferably configured to be axially displaceable relative to the pile mooring10along the pile mooring axis X within the displacement range22. The variable surface level of the liquid has the advantage that the pontoon8, together with the building4, can be totally or partially lowered into the basin24, for example, for protection following a storm warning. Advantages arise furthermore from the fact that the pontoon8can be lifted from the normal position depicted inFIG.6in the direction of the elevated position depicted inFIG.7. Beside the further advantage of being able to adapt the building development base2to the total load over the building development base2and being able to keep the distance of the pontoon8to the bottom26of the basin24within an allowable range, there also arise advantages for the comfort and accessibility of the user. The variable surface level of the liquid can, in particular provide privacy protection for the building4when the building development base2is lowered, as well as enabling ground-level access for wheelchair users and for loading and unloading purposes.

In a particularly advantageous embodiment, the building4and/or the building foundation2is provided with the connection means for connecting at least one supply line46for a connection system of the building4. The supply line46is preferably suitably guided through the supply channel48of the pile mooring10, wherein the supply line46according to another variant is configured in such a way that it can compensate for an axial displacement of the pontoon8relative to the pile mooring10along the pile mooring axis X. The supply line46guided through the supply channel48is advantageously protected from outside influences as previously described with reference toFIG.4.

As shown inFIG.6, the pile mooring10preferably has an overhang54with respect to a surface12which faces toward the building4in the normal position of the pontoon8relative to the pile mooring10. The displacement range22advantageously extends at least partially over the overhang54, so that the pontoon8can float at least from the normal position up to an elevated position within the displacement area22.

The normal position suitably corresponds to a positioning of the pontoon8relative to the pile mooring10in which the pontoon8is essentially arranged above, that is in relation to other positions, for most of the time. The displacement area22extends, for example, between a normal position in which the pontoon8is normally arranged, and the elevated position, for example, with high tide or flood, when the pontoon8floats exceptionally high, or a correspondingly adapted surface level of the liquid in the basin24.

The dimension of the overhang54determines in particular the maximum possible upward floatation height and can be advantageously adapted to local conditions, for example, a flood zone. The exemplary embodiments according toFIGS.1,2,4, and5in particular thus have a relatively small overhang54compared to the exemplary embodiment according toFIG.6.

According to the exemplary embodiment inFIGS.4and5, the displacement area22of the pile mooring10can be configured in such a way that the pontoon8can descend, from the normal position of the pontoon8relative to the pile mooring10in the direction of the liquid to a low-lying position within the displacement range. The building development base2, which is depicted in normal position inFIG.6, is especially configured for a pronounced descent, which is depicted inFIGS.8and9.

According to the advantageous embodiment depicted inFIG.1, the pontoon8has an advantageously radial overhang56which, when sunk to a ground, comes to rest on the edge of the building development base2. In one advantageous aspect, the radial overhang56enlarges a developable area of the building development base2or the pontoon8. In a second advantageous aspect, the radial overhang56is configured in such a way that the pontoon8with the overhang56can rest on an area of earth58. In this way, the pontoon8, in a low-lying position, is advantageously prevented from resting on the bottom26of the basin24because adhesive forces could occur which would prevent a refloating of the pontoon8.

In the exemplary embodiment according toFIG.9, an adhesive connection between the pontoon8and the bottom26of the basin24is prevented in that support blocks60that extend in the direction of the pontoon8are configured on the bottom26of the basin24. The support blocks60are especially configured in such a way with regard to number, arrangement relative to the pontoon8, and structure, that the pontoon8rests evenly in one plane on the support blocks60and is evenly supported. In this way, tilting of the pontoon8with the pile mooring(s)10is advantageously prevented.

The radial overhang56and/or the support blocks60can in particular be configured in such a way that an assembly chamber62is configured between the pontoon8and the bottom26of the basin24when the pontoon8in arranged in its low-lying position, especially when the liquid has been completely discharged from the basin24. The assembly chamber62advantageously serves the purposes of repair, maintenance, and inspection of the building development base2.

At least one supply line46is configured as a telescoping line in an embodiment which is not depicted in order to compensate for an axial displacement of the pontoon8relative to the pile mooring10along the pile mooring axis X.

According to another advantageous embodiment of the connection system depicted inFIGS.6to9, the supply lines46are configured, in particular, as flexible and are arranged laterally to the building4, so that the supply lines46are guided perpendicularly to the pile mooring axis X through an inlet opening in a façade20of the building4or the pontoon8in the building4or the building development base2. The inlet opening is preferably configured in such a way that it extends from an elevated position inlet64in the pontoon8, which is depicted inFIG.7, to a low-lying inlet66, which is depicted inFIGS.8and9, within the building4, so that the supply lines46are conducted in a constant position with respect to the basin24within the building4. For this purpose, the inlet opening is configured in particular as a slot that extends axially to the pile mooring axis X or a lateral recess in the façade20of the building4and in the pontoon8. The recess has in particular a width ranging from 100 cm to 40 cm and a depth ranging from cm to 20 cm, preferably a width ranging from 80 cm to 50 cm and a depth ranging from cm to 25 cm, advantageously a width of 60 cm and a depth of 30 cm. The slot-like design of the inlet opening or the execution as a recess has the advantage that a section of the supply lines46that is exposed to environmental influences can be made as small as possible.

The building development1has one technology module at least on one side of the building4and/or the pontoon8and/or the peripheral area of the building development base2. The technology module serves in particular the purpose of making available a constantly adapted length of the supply line46during an axial displacement of the pontoon8along the pile mooring axis, without at least one partial section of the supply line46being arranged loosely or unattached within the area between a utility and the connection means in the building4or the pontoon8. In a variant of the technology module, the latter exerts a previously defined tensile stress on the supply line46. This technology module can be configured in particular as a cable reel subjected to a spring force and/or as a motor-driven cable reel. With a vertical movement of the pontoon8along the pile mooring axis X and the resulting tension on the respective supply line46, the supply line46is rolled off the cable reel against the tensile stress. With a movement of the pontoon8along the pile mooring axis X, which causes a reverse movement of the supply line46in direction of the tensile stress, the respective cable reel is rotationally driven by means of the spring force or the motor power of the respective cable reel and the supply line46is rolled up onto the cable reel.

According to another embodiment, the technology module does not exert a constant tensile stress but has an electric motor with a freewheel. Advantageously, the technology module has a smooth-running shaft with ball-bearing and a motor drive. Part of this shaft are cable reels of different sizes for different supply lines46, which allow the respective supply lines46to unroll freely during a vertical movement of the pontoon8along the pile mooring axis X and the tension resulting therefrom. For rewinding, the respective supply lines46are rolled up around the motor-driven cable reel. In the exemplary embodiment inFIGS.6to9, the building development1, especially the building development base2, has in its peripheral area a utility box68into which at least one connection system is lead and in which in particular at least one technology module can be arranged.

The at least one supply line46, especially the supply line46for freshwater, is preferably routed through a lateral groove running axially to the pile mooring axis X into the pile mooring10in the pontoon8or the building4, so that especially a compensation of a displacement of the pontoon8axially to the pile mooring axis X toward the pile mooring10is possible, wherein the supply line46remains fluidically connected to the communal power grid. A reel/spool for rolling on and/or off the respective supply line46is advantageously arranged in the pontoon8or the building4. The reel/spool has, in particular, a hose reserve of respectively 7.5 m for floating or lowering the pontoon in a normal position of the pontoon8.

The building4in particular has a second breakthrough72in a ceiling70and/or the roof18in the area above the passthrough opening14, so that an overhang54of the pile mooring10can be arranged in the second breakthrough72. In the example depicted inFIG.6, the overhang54of the pile mooring10is already arranged in the second breakthrough72in the normal position, so that floating up into the elevated position, which is depicted inFIG.7, is possible. The second breakthrough72is preferably configured in such a way that it passes in its entirety axially to the pile mooring axis X through the structure, so that in a low-lying position depicted inFIGS.8and9the overhang54is guided through the building4.

The second breakthrough72is advantageously provided with a manual or automatic closure for protection from weather situations, which seals the second breakthrough72if the pile mooring10is not arranged in the second breakthrough72.

According to a variant of the building development1, which is not depicted, the passthrough opening14is arranged in an area of the pontoon8in which the building4is not arranged. In this variant, the passthrough opening14is regularly arranged in a peripheral area of the pontoon8. The overhang54of the pile mooring10can in this way be advantageously configured greater than the pontoon8and the chambers of the building4can be configured homogeneously, in particular, free of a first, second, or other breakthroughs above the passthrough opening14.

In an especially advantageous type of the building development1, which is particularly depicted inFIGS.8and9, the basin24, the pile mooring10, and the building4are configured in such a way with respect to each other that the basin24has a depth74measured axially to the pile mooring axis X, and the displacement plane22of the pile mooring10is configured in such a way in the direction of the liquid that the building4is arranged at least partially within the basin24in the low-lying position of the pontoon8.

In a particularly advantageous embodiment of the building development1, which is not depicted, the basin24, the pile mooring10, and the building4are configured in such a way with respect to each other that the depth74of the basin24measured axially to the pile mooring axis X is greater than or equal to a height76of the pontoon8, including the building4measured axially to the pile mooring axis X. At the same time, the displacement area22of the pile mooring10in direction of the liquid is suitably configured in such a way that in the low-lying position of the pontoon8, the building4is arranged at its entire height76within the basin24.

This embodiment of the building development1advantageously enables privacy protection by lowering. Solar radiation on the building4can also be further reduced in this way. A protective aspect of this embodiment is that the basin24provides protection to the building4during storms in such a way that storm gusts themselves and objects whirled up at the building4encounter a reduced surface of attack.

At the same time, as depicted inFIGS.1and6to9, the building development base2suitably has a reservoir78for liquid, said reservoir being fluidically connected to the inlet and outlet52of the basin24. The fluid can thus be directed into a circuit. If the liquid contains additives, they are, in particular, prevented from leaking into the environment.

The reservoir78and/or the inlet are particularly preferably provided with heating means. The reservoir78can serve conveniently at the same time as a thermal buffer and/or reduce the need for additives to prevent damage from freezing. The inlet and outlet52and the basin24are, in particular, especially configured in such a way that the liquid in the basin24can be kept constantly above the freezing point, in particular over 1° C.

The basin24can preferably be configured with an integrated overflow protection especially in rainy regions. This can be suitably implemented by means of float valves. A maximum level of the surface of the liquid in the basin24can be advantageous set in a particularly easy and error-resistant way. The overflow protection can in particular route the liquid into the reservoir78or a catch basin or directly into a channel.

As shown inFIGS.6to11, the pontoon8is preferably configured with at least two, in particular three passthrough openings14, wherein one pile mooring10respectively extends respectively along a pile mooring axis X vertically through the respectively one passthrough opening14of the pontoon8. This embodiment blocks both a rotation and a translation of the pontoon8on the surface of the liquid.

In an embodiment of the building development base2with two or more pile moorings10, the pile moorings10can advantageously be arranged in an edge region of the pontoon8, so that more homogeneous installation space is available in the building4, especially at the center of the pontoon8.

In plan view, in the direction of the liquid, the building development base2with at least two pile moorings10has in particular an angular profile, for example, a rectangular profile, as depicted inFIG.10, or an L-shaped profile, as depicted inFIG.11. Because the rotation of the pontoon8is restricted by the two pile moorings10, the basin24can be adapted to the shape of the pontoon8, and the pontoon8is prevented from colliding with the wall30of the basin24.

The pontoon8is advantageously provided with a manual and/or automated, in particular a hydraulic level regulation system. The level regulation system aligns the pontoon8in particular with its surface12facing toward the building4within a horizontal plane by means of slidable load entries in the float6. It is particularly advantageous if the level regulation system is configured in such a way that it can constantly monitor and preferably constantly readjust the alignment of the pontoon8. The level regulation system can advantageously compensate for weight differences which result from an uneven weight distribution of the building development1, especially over the building development base2. Furthermore, a draught of the pontoon8can be adapted by means of the level regulation system depending on the total load over the building development base2.

In addition, the level regulation system preferably has an alarm unit that sends a signal to the user when there is a weight difference that can no longer be compensated for and determines the location of the critical weight difference. As a result, the user has the possibility of detecting a critical weight difference early and adapting the weight distribution over the building development base2.

The pontoon8in particular has a plurality of floats6. InFIG.2the pontoon8is configured with only one float6. In a preferred embodiment, each of the floats6can furthermore have individual chambers which can be statically or dynamically adapted, depending on the weight distribution, by the level regulation system. For example, individual chambers or whole floats6can be flooded with the liquid, or the liquid can be drained. The liquid can be a separate compensating liquid arranged in a circuit of the level regulation system, or it can be the liquid on which the pontoon8floats. Compensation for the draught when there is an increase or decrease of a total load on the building development base2is possible, in particular if the level regulation system is connected to the liquid on which the pontoon8floats.

The level regulation system is suitably improved or made available by means of intermediate reservoirs. For this purpose, fluidic intermediate reservoirs are preferably arranged circumferentially inside the pontoon8or the building4. The liquids in the tanks of the freshwater reservoir or the wastewater reservoir are systematically circulated for level regulation, preferably with the assistance of a pump. As previously described, the distribution of the weight of the pontoon8to variable loads can advantageously be dynamically adjusted in this way.

The building development1or the building development base2preferably has a maintenance shaft. This embodiment is not depicted. This maintenance shaft is arranged in an edge region of the development base2behind the wall30of the basin24on the side facing toward the liquid. The maintenance shaft has in particular an entrance that is accessible from the outside of the basin24and a passage is especially configured in the wall30of the basin24in the area of the maintenance shaft, so that a person can access the assembly chamber62in the area between the bottom26of the basin24and the pontoon8through the maintenance shaft, at least in the elevated position of the pontoon8. The repair, maintenance, and inspection, in particular, of the building development base2is made easier in this way. The pontoon8can be suitably arranged in the elevated position and/or the normal position specifically by means of supports, the support blocks60, and/or the radial overhang56, so that the liquid can be discharged from the basin24and the space between the bottom26of the basin24and the pontoon8be maintained and be largely dry.

Particularly if electronic applications are arranged in the maintenance shaft, the opening in the wall30of the basin24leading to the maintenance shaft can suitably be fluidically sealed, so that the maintenance shaft remains dry when the basin24is filled with the fluid.

The maintenance shaft around the basin24can suitably be configured as wholly or partially circumferential. Especially if the inlet and outlets52are arranged spaced apart or, for example, on two different walls of the basin24; the inlet and outlet52are then more easily accessible for a person, which likewise facilitates repair, maintenance, and inspection.

Another advantageous embodiment is depicted inFIGS.13and14. Here, the aforementioned embodiments are supplemented with a non-flammable roof construction.

As depicted inFIGS.13and14, the building4preferably has for this purpose a flat roof construction98, which features a tub-like, water-tight, open water basin100facing counter to the direction of the basin24. The water basin100can be flooded, if needed, with the liquid from the basin24. The use of a pump arrangement has proven especially advantageous for flooding the water basin100.

In case of fire, a heat barrier is created by the water in the water basin100. According to a preferred embodiment, the water basin100has a peripheral installation height102as depicted inFIGS.13and14. As a result, the installation height102limits a maximum water height, wherein the installation height102and the maximum water height is at least 30 cm. Here, a water height of 30 cm has proven effective in delaying heating of the building4underneath the flat roof construction98.

The flat roof construction98particularly advantageously has a peripheral roof overhang104. In a lowered state of the building4in the basin24, especially in the low-lying position depicted inFIGS.13and14, the roof overhang104slots, in particular level with the ground, into a groove106running circumferentially around an upper basin edge. The basin wall advantageously protects the side walls of the building4, so that, for example in the event of fire, only the surface of the flat roof construction98, whose surface largely corresponds to that of the water basin, is exposed to the elevated temperature. In particular, without local fuel for the flames due to the submersion of the building4, a fire event (firestorm) that is driven by strong winds, passes in a very short time over the building4.

In a further-developed advantageous embodiment, the roof overhang104, in the lowered state of the building4in the basin24, in particular in the low-lying position, depicted inFIGS.13and14, slots with a flute108into the groove106at the basin edge. Advantageously, there is no contact between the roof overhang104or the flute108and the basin24or the groove106. It has additionally proven advantageous if the groove106is flooded or can be flooded with a liquid, especially the liquid in the basin24.

The groove106that is flooded with water provides cooling and protection from invasive flue gases. The contactless arrangement of the flute108in the groove106also has the advantage of preventing heat transfer.

According to an advantageous, previously-mentioned embodiment, in the event of fire, the pontoon8can sink into the low-lying position in a direction facing the liquid relative to the pile mooring10along the displacement range22of the pile mooring starting in particular from the normal position of the pontoon8. For this purpose, as in the aforementioned embodiments, the liquid is effectively discharged from the basin24. The water basin100and/or the groove104are advantageously flooded with part of the liquid discharged from the basin24. In this state, the low-lying position of the pontoon8, the roof surface of the flat roof construction98is effectively arranged level with the ground in the edge areas of the basin24and the flute108is preferably arranged in the described manner in the groove104filled with water. InFIGS.13and14, the support blocks60are in particular advantageously arranged in the basin in order to prevent adhesive connections between the pontoon8and the bottom26of the basin and at the same time unburden the flat roof construction98in the low-lying position of the pontoon8.

The flat roof construction98and/or the roof overhang104is suitably made of fire-resistant materials, especially alloyed and/or unalloyed steel and/or ceramic composites.

The flat roof construction98with the water basin100preferably has the possibility of providing a classic rooftop garden with low lichens and/or moss and/or grass. The plant substrate used herein is preferably native soil enriched with perlite and expanded clay for weight reduction.

It is advantageously made possible to configure the aforementioned embodiments in modular form. The building development base2and the building4are especially designed in modular fashion in such a way that the building development base2can be effectively separated from the building4in a non-destructive manner, so that assembly and disassembly can be carried out repeatedly.

A relocation of the entire building structure via heavy transport over land or by waterway can thus be realized with the use of prefabricated, preferably standardized components, in particular a multipart pontoon and/or displaceable wall elements and/or a standardized basin. A foundation2of a building development1having a pontoon8, on which a building development, especially a building4, can be arranged is also part of the invention. The building development base2corresponds to one of the aforementioned embodiments of the building development base2according to the invention.

A pile mooring10of a building development1having a pontoon8on which a building development, in particular a building4, can be arranged is also part of the invention. The pile mooring10corresponds to one of the aforementioned embodiments of the pile mooring10according to the invention.

The invention is not limited to the depicted and described exemplary embodiments but also comprises all equivalent embodiments in the sense of the invention. It is expressly emphasized that the exemplary embodiments are not limited to all the characteristics in combination, but rather that each individual, partial feature can also have an inventive significance of its own, separately from all other partial features. Furthermore, the invention is not to date limited to the combinations of features defined in claim1and/or19and/or20but can also be defined by any other desired combination of specific features of the entirely of disclosed individual features. This effectively means that virtually any individual feature of claim1and/or19and/or20can be omitted or replaced by at least one individual feature disclosed in another part of the application.
