Abstract

The invention relates to the construction and can be used, in particular, in the paving of buildings and structures. The purpose of the invention is to facilitate installation. The method of mounting the trailing cover includes joining precast concrete slabs by loopbacks, installing these plates in the design position, fixing the end plates to the support contour. The docking plates carried out on a flexible grid. The mesh is tensioned at the level of the lower surface of the coating between two mobile platforms. Each of the platforms is installed in the alignment between the two supports on the inside of the respective support. After tensioning the grid on it with a lifting device, plates are laid with their subsequent connection. Then the grid tension is relaxed and the platforms are moved along with the grid to the next one. As a platform, temporary roller supports that move along the ground can be used.

Description

The invention relates to the construction and can be used, in particular, in the paving of buildings and structures.

There is a known method of mounting a coating, in which the reinforcement of the plates is installed parallel to the guy and welding of the adjacent plates.

The disadvantage of this method is the limitation of its use in round-shaped buildings.

The closest to the technical proposed method is the installation of a high visibility coating, which includes the joining of precast concrete slabs by means of loopback outlets and their installation in the design position with the fastening of the end plates to the support contour.

The disadvantage of this method is the difficulty of mounting the coating.

The aim of the invention is to facilitate installation.

The goal is achieved by the fact that the joining of plates is carried out on a flexible grid, stretched at the level of the lower surface of the coating between two moving platforms, each of which is installed in a place between two supports on the inner side of the corresponding support, after tensioning the grid onto it with a lifting device followed by their combination, and then weakened

tensioning the net and moving the platforms along with the net to the next one.

As a platform, temporary roller supports that move along the ground can be used, or a trolley that is moved along this contour suspended to the support contour.

After installation of the plates in the design position, monolithing of the cracks can be carried out.

FIG. 1 shows a plan for mounting a coating using wooden supports; in fig. 2 - the same, with the use of temporary Katkov supports; in fig. 3 - the same, with the use of a hanging trolley.

The method of mounting the coating of which is carried out by means of two moving platforms 1. The size of platform 1 is adopted for reasons of stability and minimality of its mass. The height of the platform 1 should reach the bottom of the plates 2, laid in the coating. In the extreme to the axis of the flight, the upper bars of the platform 1 should be sealed with three or four hooks, on which a large grid of 3 out of four wire-strands is pulled. The unchangeability of the position of the platform 1 is ensured by fixing them to the runs 4 with the help of the simplest folding clamps located on the platform 1 from the side of the run at the height of the bottom of the latter. In order to avoid the possible deviation of the columns and runs by the force of gravity of the laid plates of the coating, it is necessary to arrange in the neighboring spans the bracing of the columns 5 of this span. Then, using a truck crane, plates 2 are placed on the grid and the top of the platforms 1. They are fastened with bolts from the outside (from the overhang of the coating above the end wall of the building), and at the joints of the loop-shaped releases of the plates 2 facing the adjoining point of their subsequent row, clamps are put,

When all the plates 2 of the first row have been laid, the tension of the grid is relaxed and the platforms 1 are moved with the grid 3 to lay the plates 2 of the next row. Temporary roller supports 6, which move along the ground (FIG. 2), or a trolley 7 suspended from the support contour, which move along this contour (FIG. 3), can be used as platforms.

After installation of plates 2 in the design position, if necessary, monolithing of the joints can be carried out,
