Lifting of horizontally cast on-site wall panels

Abstract: These improvements consist in providing such pieces having means to ease moving thereof by ancillary means such as cranes and the like in such a way that moving, which involves hanging of the pieces, will not impair their resistant structure and will not impair the corresponding standardised profiles that serve as a frame of the pieces Stiffening the structure. Said means comprise a number of hooks distributed at the vertexes of the pieces and at the middle area of their major bases. Raising up of the pieces as well as moving thereof in a comfortable and effective way are made possible by means of the corresponding pulleys and IPN profiles without impairing the pieces.

Description: The present Addition Patent application relates, as stated in its title, to an improved BUILDING CONSTRUCTION METHOD which novel manufacturing, conformation and design features fulfil the purpose to which it has been specifically designed, with a maximum safety and effectiveness. More particularly, the invention refers to an improved building construction method comprising the steps of directly moulding on the floor or on the pavement of the building flat pieces which are meant to form the building side walls. They are obtained by disposing the suitable reinforced concrete rod lattice as well as the openings of the corresponding masses of reinforced concrete in the space defined on such pavement by a frame formed by detachably interlinked metal rulers appropriately sized which are placed thereon. Said pieces are horizontally resting on the pavement until setting up has been completely and then they are disposed in the up-right direction that they have to assume altogether in the building. Said improvements consist in providing such pieces having means to ease moving thereof by ancillary means such as cranes and the like in such a way that moving, which involves hanging of the pieces, will not impair their resistant structure and will not impair the corresponding standardised profiles that serve as a frame of the pieces stiffening the structure. Said means comprise a number of hooks distributed at the vertexes of the pieces and at the middle area of their major bases. Raising up of the pieces as well as moving thereof in a comfortable and effective way are made possible by means of the corresponding pulleys and IPN profiles without impairing the pieces. The frame of the above mentioned pieces is provided with means that allow assembling of several pieces, either being aligned or angled in such a way that, once they have been placed, they can be immobilised relative to one another by simple operations such as welding or the like along with the corresponding conventional joints thus allowing to build up large longitudinal walls with a minimum time. Even in earlier improvements such as that disclosed and claimed in the Addition Patent n° ES-A-544038 (application n° ES 8608612) the inner structure of the made up piece was arranged so as to have projecting ends used to move them, the present improvements replace said technical solution with the provision of a plate having a hook and which is fixed by the suitable means to the profiles that frame the pieces or to their major bases or to their minor bases. Accordingly, manufacturing of the pieces becomes faster thus preventing said side reinforcing members (basically profiles having an U-shaped cross-section) from being machined, i.e. providing them with the corresponding bore or hole intended to exit the reinforcing inner bar ends allowing to form the hook as ancillary means for moving and raising such pieces. The above mentioned hooks are provided at the ends of the reinforcing profiles which are formed in any of the piece bases. Altogether allowing for a faster and short time manufacturing of said pieces. In short, by means of the above mentioned improvements the piece raising up is facilitated by a four point arrangement where the entrainment cables of the crane or the like can be attached to. Two of these points are located at the reinforcement profile upper corner and the other two are located at the middle height of the side profiles. As for the additional profiles that will be disposed in order to allow attaching of the two pieces forming a wall or a corner, a desirable number of them will be placed therein to ensure the wall stiffness. A further improvement of the present application consist in manufacturing outside walls that require an high isolation degree by means of two of the provided pieces in the building construction method disclosed in the main patent n° ES-A-540232 (application n° ES 8602189) and in the next Addition Patents. Isolation provided in said walls is achieved in a different way by interposing them either inside one of the pieces as intended, described and claimed in the Addition Patent n° ES-A-2063722 (application n° ES 9301707) in the name of the same applicant or by providing two pieces forming a sandwich with a plate of an isolating material of any suitable nature according to each condition, in such a way that at the corresponding side bases or at the upper or lower bases there is provided a wider U-shaped cross sectional profile allowing to attach the three plates: the two plates made up of the mentioned concrete plus the proper isolating plate. Further details and features of the present invention will be apparent from the following description, which refers to the accompanying drawings that schematically represent the preferred details. These details are given by way of example, which refer to a possible case of practical embodiment, but it is not limited to the disclosed details; therefore this description must be considered from a illustrating point of view and without any type of limitations. A detailed list of the various parts cited in the present patent application is given below: (10) flat piece, (11) mass of concrete, (12) frame, (13) cable, (14) point of anchorage, (15) point of anchorage, (16) frame, (17) profile, (18) pulley, (19) hook, (20) plate, (21) hook, (22) plate, (23) hook, (24) roofing piece, (25) insulator, (26) mortar, (27) roofing, (28) plates, (29) plates, (30) soldering points, (31) pieces for receiving hooks (32) ceiling board. Figure n° 1 is a perspective view of the moving system of the flat piece (10) with the improvements introduced in the object of the present invention. Figure n° 2 shows a detail about the nature and constructive form of the points of anchorage (14) by means of plates (20-22) and hooks (21-23). Figure n° 3 is a partial cross-section elevational view showing a facade section having more than one floor and being built according to the object of the present improvements. Figure n° 4 is one of the possible embodiments of the present improvements in building a gable-roofed floor. Figure n° 5 is a perspective view showing the shape of the junction between two plates (10) being helped with plates (29). Figure n° 6 is a top plan view of a ceiling board (32) provided with pieces (31) for raising it up. In a preferred embodiment of what is the object of the present invention and as it can be seen from figure n° 1, the flat piece (10) is made up from a mass of concrete (11) duly reinforced by means of the corresponding bars, not shown in the figures, protected at the edges thereof by frames (12) and (16). Said frames could be preferably normalised profiles having a U-shaped cross-section and soaking up the mass of concrete and in turn protecting it and allowing to place said flat pieces (10) with other similar pieces. One of the present improvements consists in providing points of anchorage at the vertexes or at the confluence points between the frames (12) and (16). Alternatively, another object of the present application is the provision of further points of anchorage in the frames (16) and in one of the profile wedges which cross-section is U-shaped. The four points of anchorage are formed by a plate (22) welded to the frames (12) and (16) and to the profiles which are forming them, and a hook (23) welded to the plate (22). The above described arrangement and nature of the points of anchorage allow, as it can be seen from figure n° 1, moving the piece by means of cables (13), pulleys (18) and beams (17), by means of a crane provided with a hook (19), so that stresses involved by moving of such a heavy piece are evenly spread throughout its volume with said movement entailing no deformation which could involve wasted pieces due to failure, cracking or inner damage not being appreciated with the naked eye. A further object of the present improvements consist, as it can be seen from figures n° 3 and 4, in building a wall by means of two flat pieces (10) forming a sandwich together with an isolating piece (25). At the side up-right bases there are provided respective U-profiles, either only one profile or an additional third profile soaking up the profiles or frames of each of the pieces (10). A further embodiment can be seen in figure n° 6; this embodiment does not fall within the scope of claim 1 and consist in providing a plate (32) specially for ceiling having corresponding pieces (31) for receiving hooks and provided with an isolating layer (25) as well as a mass of mortar (26) onto which corresponding, slates, root tiles and the like are to be placed. Another object of the present invention offers the possibility of assembling flat pieces (10) through the soldering points (30), as it can be seen from figure n° 5, by providing a number of plates (28) and (29) properly welded to the frames or profiles (12) and (16) regardless of whether the corresponding joined pieces are placed between the minor side bases of two adjacent flat pieces being arranged to form a wall. Once having been sufficiently described what the present patent application consists in accordance to the enclosed drawings, it is understood that any detail modification can be introduced as appropriate, provided that variations do not alter the essence of the invention as summarised in the appended claims.
