Abstract

The invention relates to the construction, in particular to the erection of buildings and structures by the method of lifting floors. The aim of the invention is to simplify the construction of a multi-storey building while simultaneously reducing the lifting capacity of the lifting equipment and reducing the material consumption of the building. At ground level, a package of floors is made of alternating interroom partition walls and 8 floor slabs pivotally interconnected, then the floor slabs 8 are lifted along guide columns 2. The interroom wall partitions 5 under their own weight are opened to the design position. When concreting the package of floors in each slab, overlapping 8 and partition walls 5 establish U-shaped embedded elements associated with reinforcement. The embedded elements of the slab 8 are connected with the embedded elements of the corresponding partition plate 5 pivotally by means of C-shaped brackets, the seams of which are directed in opposite directions. The floors are lifted alternately, starting at the top. Monolithing of seams after lifting is performed first in the space between the embedded elements, and after dismantling the C-brackets in the remaining space. 4 il.

Description

formwork for concreting the interroom walls-partitions 5 of the first floor, and these partitions are solid slabs across the entire width and height of the partition wall.

The reinforcement 6 from the end of the longitudinal face of each slab of the partition 5 is welded horizontally with U-shaped embedded elements 7. The same embedded elements are welded to the fixture of the slab 8 of the ceiling. Then, after concrete has been concreted and hardened, the mortgage elements 7 of the slab 8 are connected with the mortgage elements 7 of the corresponding slab of the wall-partition 5 with C-shaped brackets 9 to form the hinge node 10. The brackets 9 are interconnected by a detachable hinge axis 11 directed in opposite directions to ensure a reliable grip of the mortgage elements 7 only from above, as shown in FIG. 4. The joint of the inset elements 7 is closed with something to prevent the ingress of the solution when concreting the next floors. Then the concreting of the next (overlying) floor and the hinge connection of its embedded elements 7 are carried out. These operations are carried out until a package or stack of all the floors of the building is formed.

In order to facilitate installation and eliminate breakage when lifting floors by 8 floor slabs, the dimensions of the interroom wall partitions 5 are slightly lower than the design for free opening. In order to provide a continuous surface for concreting of the 8 floor slabs, the areas of the inventory formwork walls free from concreting are filled with technological void inserts 13. Thus, a package or stack is formed of a corresponding number of floors, each of which consists of a floor slab 8 and interroom partitions 5 hinged with it. After that, lift 14 is installed at the top of columns 3, lift 15 is attached to lift 14 of the upper floor of the building and t its rise to the design level, where it is fixed on the columns. Simultaneously with the lifting of the slab 8 of overlap, the interroom walls-partitions 5 assume their design vertical position, turning around the axes of the 11 hinges under their own weight. After that, the tows of the 15 lifts are passed through the previously made holes in the slab V) are connected to the slab of the next floor, and again

lifting and securing it in the design position. Further, the cycles for raising floors are repeated until the building is fully erected. Monolithing of seams can be performed both after the second floor is installed on top of the design position, and after the last (bottom) floor is installed, i.e. at the end of installation. The lower gaps are covered with a floor tie, while the upper and side gaps are covered. Monolithing of the seams is carried out in the space between the embedded parts 7. After hardening, the C-shaped brackets 9 are dismantled, removing the axle 11, and reused during the construction

other buildings. After that, monolithic seams are made at the locations of the embedded elements of floor slabs and walls, filling the space previously unfilled with mortar.

Such an embodiment of the method makes it possible to erect high-rise buildings that are not limited by the carrying capacity, since the loading capacity corresponds to the mass of one floor and is hardly

limits the height of buildings being erected; reduce material consumption by using universal inventory hinge devices; increase the level of sound and temperature insulation through the use of

solid monolithic interroom partitions.

Formula of the Invention The method of building a building and construction by the method of lifting floors, including the construction of the foundation, the installation of columns with elevators, the formation on the foundation of a package of floors of slabs and walls hinged to them, their lifting to the design position with subsequent monolithing seams, characterized in that in order to simplify the construction of a multi-storey building while simultaneously reducing the load capacity of lifting equipment and reducing the material consumption of the building, when forming a package of floors in each slab and walls, horizontally connected with reinforcement U-shaped mortgages are installed elements, while the embedded elements of the slab are connected with the embedded elements of the corresponding slab of the wall by means of C-shaped brackets, the seams of which are directed in opposite directions, the floors are lifted alternately with the installation in the design position, starting from the top, and the monolith seams in the space between the embedded elements, and after solidification of the solution the space between the mortgages of the element, the subsequent filling of the solution with places, and after the mortar has hardened, the mortgage elements of the plates dismantle the C-shaped brackets from the floors and walls. x h -z 13g2 -z fig 1 Vis.
