Insulated log item
The invention relates to a log item from wood, intended for installation on a similar log elements for the formation of a wall structure using the method of the so-called gussets. The technical result of the invention is to reduce the log element in the vertical direction. Log element includes an outer part, the inner surface of which is provided with grooves, passing in the longitudinal direction of the timber item, and spacers, designed to hold the outer parts supported in mutually spaced relation. The empty space between the surface parts filled with insulating material, preferably polyurethane. 2 s and 5 C.p. f-crystals, 3 ill.
The present invention relates to a log element, as described in the preamble, paragraph 1, of the formula.
Usually timbered houses are made of solid logs, both ends of which are formed recesses for corner connections, logs are placed on top of each other and combined by the beam angles of the respective walls of the house. Homes made of logs, the United "will Lastochka to use this method for the construction of country cottages and houses. However, the heat transfer coefficient of the walls consisting of natural logs of the United "swallow's tail", is very high and does not allow to provide the necessary isolation. The insulation of such constructions made of logs, joined at the corners, is a serious problem, especially when the Builder wants inner surface of the walls had the appearance of old log walls with logs, clearly visible from the inside of the building for the sake of appearance.
To improve the insulating properties of the elements of logs, preserving their mechanical strength, bearing capacity and resistance to twisting in patents Sweden NN 440250 and 457456 encouraged to apply log items that have wooden exterior part, which surface faces inside, provided with grooves which run in the longitudinal direction of the log element. These outer parts are held spaced apart by means of spacers, and the empty space between the outer parts filled with insulating material, preferably polyurethane, which is when he cures secures the outer parts and spacers in place. The outer parts of these well-known log items or completely pogledamo in cross-section, formed by a single panel item or multiple cells connected in the panel.
One problem associated with these known isolated timbered elements is the fact that a wall built of them, will dry out and shrink over time, thereby the height of the wall will be reduced. If the wall has a height of about 2 meters, the degree of this shrinkage may be high, such as 5 see These changes in size, which continued for one to two years, occur transverse to the fibre direction, which means that the loss of wood in a vertical direction of the outer parts of each of the mentioned known log panel will cause great losses to the walls in General, when they are taken together. Therefore, for walls made from these log items, you must allow enough time for precipitation before you spend any decorative treatment, resulting in prolonged erection time and high cost.
In practice, it is established that the shape of these log items never ceases to completely change the result of the fact that they are constantly exposed to changes in the condition the year, when the relative humidity of the outside air is higher, the wood inside and out log walls dries differently. The result of this is the high voltage and the associated changes in the profile or in the form of elements of logs. Therefore, the wall panel or similar decorative elements mounted on the inner surface of the log walls will be subjected to bending or cracking.
Accordingly, the present invention is the creation of the log element that will have minimal shrinkage in the vertical direction in comparison with the known isolated timbered elements, which is the natural form of a round log and outer parts which are fixed in all directions using spacers to avoid the risk of changing the shape of the log element.
Another objective of the present invention is the use of surface wood or bark in the manufacture of the proposed log item. The term surface wood refers to the most distant from the centre pieces sawn from logs and having so much wane edge that is considered uneconomical about the CLASS="ptx2">
These goals cannot be achieved with known log elements. However, these objectives are achieved with the proposed beam element having distinguishing features disclosed in the claims.
Hereinafter the present invention will be described in more detail with reference to non-limiting example of its execution illustrated in the attached drawings, in which:
Fig. 1 is a perspective view mutually United timbered elements, in accordance with the present invention, of which the top element of the logs shown partially in section, one end part of the log element is shown separately from the rest of the logs;
Fig. 2 is a view in cross section of one end part of the log element in accordance with the present invention; and
Fig. 3 is a view in cross section of one end part of the log element according to another embodiment.
Log element 1 shown in Fig. 1, has an outer layer in the form of a variety of surface panels, made of prefabricated elements 2 and astrogenic to specific forms, which allows you to connect these elements, for example, by gluing surface parts 3, in which the self-supporting element, inside the log element arranged in any order along the entire length of the spacers 4. These spacers 4 are intended for reception of efforts to stabilize and secure fit with the outer parts 3 formed panel elements 2. In order to be able to put a log on top of each other and get essentially continuous heat insulating layer on the entire foot, the insulating material 5 passes across the beam, i.e. from the top to the bottom of the logs along the entire length of the log. In this regard, the underside of the log includes a longitudinal receiving groove 6, while the upper side of the log has a shape corresponding to the shape of the groove 6.
Items 1 logs can be joined together using known way corner joints and possibly through a link placed in the stop log elements, using rods, working on stretching, passing through the erected wall. For example, to connect together timbered elements 1 each log is made with a constricted part near each end, or in those places where the logs should be connected with the beams intersecting wall structure, i.e. on each side of the logs can be formed to be provided with a groove 8, which has a depth corresponding to half the thickness mentioned log element or the radius of the round log element, and which corresponds to the shape of the upper surface located below the log element, as shown in Fig. 1. This makes it easy to adjust the top log member to the bottom of the log element, as shown in Fig. 1. However, no matter which way corner joints insulated layer 5 will always go to the top and bottom sides of each groove with fully insulated walls with no way to cold in the corners, while the insulating material will act so as to form a completely sealed gusset log when the elements are combined together, as shown in Fig. 1.
Fig. 2 is a view in cross section of the first versions of the log element 1, in which each panel element 2 in a log element 1 is turned outside the visible outer surface 9 and facing the inside surface provided with a longitudinally running grooves, and the panel element 2 is bent accordingly to obtain a circular log item. In order Mohanty stably connected with each other, one longitudinal edge of the panel elements 2 provided longitudinally projecting lug 10, while the other longitudinally protruding edge of the panel elements provided corresponding longitudinally through the groove 11. The protrusion 10 on the respective panel elements is intended to enter into engagement with the corresponding groove 11 on one side of the adjacent panel element 2, whereas the groove on the other side of the panel element is designed to receive the protrusion of an adjacent panel member. Besides achieved thus stabilizing effect, the design of the protrusion and the groove is also designed to prevent water infiltration. Facing the inside surface of the Central part of each panel element 2 is also provided with a longitudinally running groove 12, acting to prevent deformation of the panel elements 2 to their Assembly.
When machining the panel elements 2 visible surfaces, facing outwards, panel elements give rings that follow the curvature of the beam that is in its natural form, so when it's assembled, ready log entry will have the appearance of a log obtained from a tree trunk. The outer parts 3 formed pan the th of these spacers has the shape of a square frame design, with vertical and horizontal intersecting frame elements, which are connected together and contain protruding end parts 13, 13'. In one practical implementation of the present invention, each spacer includes at least four wooden element 14, 14' of the spacers arranged in a square frame structure 14. The spacer elements are vertically and horizontally so that they cross each other, respectively, are connected together and have the outer ends 13, 13', which protrude from their points of mutual intersection at right angles to each other.
Protruding end parts 13, 13' square spacers 4 are taken longitudinally through the grooves or recesses 15, 15' formed on the facing inside surfaces of the respective panel elements 2. As can be seen in Fig. 2, when the outer parts of the formed panel elements are collected, the outer parts will be held together due to the fact that the protruding outer ends 13, 13' of the spacers are in the notches or grooves 15, 15', while the outer ends of the stick, for example, in the slots. This design ensures that the outer part 3 is ready log element 1 will be connected DIY exterior parts from each other, for example, their rupture. For making the effort and exertion, which is subjected to a log element, at least two wooden spacer element 14 will be preferably essentially vertically and at least two spacer element 14' will be essentially horizontally.
For the best use of the permissible load of wooden elements, in accordance with the present invention, it is important that the spacers 4 each log element were located essentially in the same vertical plane when the log elements 1 are stacked one upon the other. When the top edge of the wall made of wooden elements 1, in accordance with the present invention, spacers, arranged so that the force generated by the applied load will be transmitted through the struts down to the bottom surface, on which lay a wall. The amount used of the spacers 4, their size and location determined primarily by the desired structural strength, made with timber items 1, although the number used spacers 4 should be small, since they form a path for the cold.
One Vanemuine essentially in insulating polyurethane foam 5. This is especially important in the above-mentioned practical implementation of the present invention in which the spacers 4 are made of four wooden elements 14, 14' arranged in the form of a square frame design, which should be kept from contact with the surrounding atmosphere to prevent shrinkage. It is also important that the fibers of the wooden elements 14, 14' spacers were oriented in the longitudinal direction of the spacer elements to further reduce the risk of shrinkage. As a result of such closure elements 4 spacers, transferring the load, shrinkage log element 1 in its transverse direction is very small or almost absent.
Before describing the manufacturing log element, in accordance with the present invention, it should be mentioned that before fastening together of wooden elements cause the appropriate glue all the joints, although it should be known to the person skilled in the technical field.
Log element 1 in accordance with the present invention, is produced as follows. Two panel element 2 connected together through the medium of their respective grooves 11 and protrusions 10 on each side of the lower half to the match the dimensions of the finished log element 1. The panel elements 2 is fixed in place in the respective spatial relationships using spacers 4, and the spacing of the spacers depends on the required mechanical strength of the log element. The so formed unit is then removed from the mold in which only partially molded exterior of the unit will protrude slightly outward from the upper part of the mold halves, where each outer part can now be completed by connecting each of the remaining two panel elements 2 with the corresponding partially molded outer parts 3 through the medium of their grooves 11 and protrusions 10.
In this regard, it will be clear that the "impossible" fixing of panel elements, linked with the casing in all directions, as a result of interaction of the spacers 4 and the outer parts allows to make the outer part, by a set of mutually connected panel elements 2, the protrusions 10 and the grooves 11 which are engaged with each other, allowing a limited, but still enough movement to bring together timbered elements 1.
When the form is closed by placing the upper half to the lower half of the form it is filled with the curing of peoplestreme. When the foam has hardened, molded log element is removed from the mold. Then the lower side 6 log item 1 propisuvat to obtain log-element circular segmental cross-section, and the upper side 7 of a log shape, which mates with the bottom side of the log, as shown in Fig. 1, thus, the upper side of the log element is taken popisovanou lower edge overlapping the log element during Assembly of the wall.
As can be seen in Fig. 1, the ends of the respective logs propagowany and is connected to the end elements 16. These mechanical elements consist of a solid end caps are made from natural logs and turned on the lathe to fit in the cavity milled in the end of the log element 1. The end elements 16 form the end of the tube, which provide full closure of insulating material 5 in the appropriate log items 1 wall structure. End of the tube 16 are held in the respective ends of the wooden element 1, they are glued and pressed against him. To avoid the tendency of shift end of tube 16 provided with grooves.
Although not shown, between the log is permeable seal. Either the top element of the panel elements 2, located adjacent to the area between two adjacent beam elements 1, can be provided longitudinally through the groove, the conductive water.
Fig. 3 is a view in cross section of another variant of the log element, in accordance with the present invention, in which in addition to the groove 6 formed on the underside of logs and profiled on the advanced upper side 7 of the log, the upper side of the log provided with a continuous, longitudinally passing the guide strip 17, whereas the lower side logs supplied with a corresponding longitudinally through the groove 18 on each edge of the groove 6. This ensures that the log items will be recorded on the spot, when they are placed on top of each other to form a partition wall.
In the scope of the present invention to item 1 of the workpiece can be given a different cross-sectional shape, and not that shown in the illustrative implementation, and log element can be made of different material. The grooves, which form in a log items 1 to connect them in the wall structure, you can, of course, to shape, other than until the th design, made of wooden elements 1. Also, it should be clear that the above-mentioned spacers 4 can be made of a suitable material, such as plastic, aluminum or similar material, not only from wood, and that panel members can be placed adjacent to each other, which will shape a solid circle log element, when it is shown in transverse resized
