Description

one

The invention relates to construction and is intended to affect buildings with monolithic walls and prefabricated floors.

There is a known method of erecting buildings using sliding formwork, which involves the erection of monolithic walls in sliding formwork and the subsequent installation with monolithic prefabricated ceilings. In order to create support sites for the overlap in 1 wall, nests are left when they are formed. Floor slabs are installed on temporary mounting and monolithic. As a result, intermittent overlap of the ceilings on the walls and unequal joints t1 is obtained.

The disadvantage of this method is that the installation of floors in most cases becomes possible only after the completion of concreting of walls to the full height and dismantling of the working floor. This greatly complicates the construction of floors and lengthens the construction time. The assembly of prefabricated floors in the process of lifting sliding formwork with a certain lag behind the erection of the walls is associated with some difficulties. In addition, additional work is required related to the assembly and disassembly of the installation tables and the creation of sockets.

 The closest to the invention, according to its technical essence and the achieved result, is the method of erection of buildings, including the installation of panel formwork, concreting walls with formwork and laying the ceiling 23.

The disadvantage of this method is that the solidity and equal strength of the butt joints are not required. The ceiling is blocked with a monolithic wall due to the formation of technological joints, while these sections are the most loaded. Difficulties arise in the continuity of the reinforcement of the walls. In addition, the concrete is laid in a formwork with a height to the floor and when it is dropped, the process of delamination is observed.

The purpose of the invention is to improve the quality of the erected structures by ensuring equal strength of the wall-joints with overlapping and preventing the separation of the concrete mix.

This goal is achieved by the fact that according to the method of erection of buildings, including the installation of shield formwork, concreting walls by means of formwork and laying the floor, the walls are concreted to an incomplete floor height, after.; This is done by laying the ceiling with a gap from the sten and leaning them on the formwork panels, and then concreting the walls for the remaining height while simultaneously filling the gaps between the walls to form the masses and the floor slabs. The drawing shows the formwork for 25 VA. construction of buildings by the proposed method. The method is carried out as follows. First, formworks are installed, the upper L-shaped parts 1 of one of their shields (shown by a dotted line in the drawing) are tilted relative to the lower parts 2 around axis 3 by means of screw struts, the concrete mix is poured into the resulting funnel and the walls are concrete cast at an incomplete height, for example, a height equal to height of the lower half of the floor. Next, the upper parts 1 of the shields are brought to their initial position, they are fixed with the help of fastening elements 5 and sht 6, indicate prefabricated intermediate floors 7 at some distance from the wall, i.e. with a gap (on a comparatively little loaded area) with a support on the formwork boards 1 and at the same time concrete the wall to the remaining height (on the upper half of the floor), fill in the gaps between the wall and the floor to form macuses. After the concrete has acquired the required strength, the formwork panels are dismantled, for which purpose the fastening elements 5 and the strips 6 are removed, under

jacks 8 and screw stabilizing devices 9 are attached, if necessary, also rotate brackets k. The panels under their own weight are detached, resting on the wheels 10 and rolling out of the formed cell. To increase the turnover of the formwork and to maintain the overlap, temporary racks 11 are used. The prefabricated overlaps are provided with reinforcements connecting the overlap between themselves and the wall. Since the concrete mixture is placed on the incomplete height of the walls and at the same time

with the homogeneity of concrete walls and equal strength of the junctions. In addition, due to the fact that the slabs are laid on the formwork after half of the walls have been concreted, the strength and walls of the blocks (t. e. fill the gaps) ensures the continuity of the reinforcement of the walls. Claims The method of erection of buildings, including the installation of panel formwork, concreting the steels by means of formwork and laying the floor, characterized in that, in order to improve the quality of the erected structures by providing equal strength of the wall joints with the floor and prevent stratification of the concrete mix, the walls are concrete the full height of the floor, after which the floor is laid with a gap from the walls and supported by them on the formwork panels, and then the walls are concreted to the remaining height with simultaneous filling Zorov between the walls and the overlap of and formation of beacons.
