(54) METHOD OF BUILDING BUILDING

one

The invention relates to the construction, in particular to the work on the reinforcement of floors during the construction of monolithic multi-storey buildings.

There is a method of erecting a monolithic reinforced concrete building in a sliding formwork, including simultaneous continuous concreting of walls and floors in a vertical position and subsequent rotation of the floors to design position 1.

This method is characterized by increased complexity due to the need to install the reinforcement overlap with separate rods when reinforcing the slab in the vertical position, as well as because of the work on turning the concrete reinforced concrete slab in a horizontal position and grouting both surfaces using slides formwork.

The closest to the predicted of known technical essence and the achieved result is the method of construction of the building, including the erection of walls, installation of slab formwork, concreting the upper interfloor slab, sequential movement of the latter to the level of the underlying slab, floor reinforcement and concreting of slabs and dismantling the formwork overlaps on the lower floor of the building 2.

The disadvantage of this method is the need to perform work on the reinforcement of floors with a scattering of individual rods, which leads to greater labor intensity, increases the construction time of buildings.

The purpose of the invention is to reduce the complexity of the reinforcement work in the installation of floors.

The goal is achieved in that according to the method of erection of a building, including erection of walls, installation of floor formwork, concreting of the upper interfloor floor, sequential movement of the latter to the level of the underlying floor, floor reinforcement and concreting of floors and installation of floor formwork on the lower floor of the building after the walls were erected the lower tier of the concrete is stacked on each other sequentially pivotally interconnected overlapping reinforcement packages, carried out Each package of overlapping pa pa corresponding to the design height, fix the upper overhead reinforcement package on the wall, and before installing the ceiling formwork to the design position of the upper overlay, suspended scaffolding is attached to it, fix the downstream reinforcement package on the wall relative to the overlying fixed package, disconnecting the latter and turning it to the design position, after which concreting of the corresponding interfloor overlap is carried out.

FIG. 1 shows the lower position of the sliding formwork; in fig. 2 - the upper position of the sliding formwork; in fig. 3 shows the initial moment of lowering the ceiling formwork; in FIG. 4 - reinforcement of floors.

The method for erecting buildings in gliding formwork is as follows.

On foundation 1, sliding formwork 2 is mounted. Lift formwork 2 is raised and walls 3 are concrete cast to a height of, for example, three floors. At the construction site, ku delivered factory-made reinforcement packages 4 for floors, including sets of enlarged grids and frameworks. The packages are then delivered in 4 sets to each cell of the building to the level of foundations 1, then they are sequentially connected to the main line. Thereafter, the bush of the bags 4 is attached to the sliding formwork 2 with the help of the pullers 5 so that the upper bag of the bags 4 is below the suspended scaffolds.

The rioc.ie of this concretes the walls 3 of the building in sliding formwork 2 to its full height. When concreting into the walls 3 at the level of floors, the embedded parts 6 are installed for the subsequent fixation of the packages 4.

At the end of concreting the walls, 3 beads of bags 4 are attached, for example, to a crane, disconnected from the sliding formwork 2 and lifted until each bag reaches 4 of the design floor height. After that, the upper bag 4 of the bead is fixed in the embedded part (upper) 6. Then the sliding formwork 2 is dismantled and the floor formwork 7 is installed using the crosshead 8 so that its working floor, in the position when formwork 7 is connected to the beams 9 was at the level of the upper interfloor overlap. Suspended scaffoldings are attached to the formwork 7 floors. 1. From the scaffolding 10, 3 packages 4 are fixed on the wall,

located directly under the formwork 7 overlap. Upper bag 4 is detached from wall 3 and rotated into a horizontal position.

After that, the package is disassembled, the grids and reinforcement frames are laid in the design position and concrete is laid. Next, the process of concreting floors 11 is repeated until the device of the lowest floor. After that, the slab formwork is removed and removed from the building.

This method makes it possible to reinforce floors with enlarged grids and frames, to increase labor productivity, and to reduce the duration of construction.

The expected annual economic effect from the maximum amount of use of the proposed invention may be 75 thousand rubles.
