Description

one

The invention relates to construction and can be used to strengthen the frame frames of buildings in operation.

The purpose of the invention is to reduce metal consumption.

FIG. 1 shows a multi-span frame structure with reinforcement frames; in fig. 2 shows section A-A in FIG. one.

The frame structure of columns 1 and crossbars 2 is reinforced with reinforcement frames containing T-shaped elements 3, fixed with cuts 4 on columns 1 forming oboy.my. The ends of the shelves 5 of the T-shaped element 3 are connected to the lower part of the stand 6 of the T-shaped element 3 by pulls 7. The supports of the 6 are supported on the foundation or on the underlying structures by the base 8. Between the shelves 5 of the T-shaped elements 3 and the crossbar 2 of the frame structure have spacers 9.

The reinforcement of the frame structure is carried out as follows.

1206414

The reinforcement frames are mounted, first they create a prestress in the shelves 5 T-shaped elements 3 by pulls 7, which connect the ends of the shelves of the T-shaped elements 3 to the lower parts of the supports 6 of the T-shaped elements 3. This operation can be performed in specialized workshops. In addition, the prestressing can be created by placing loads on the ends of the shelves 5 of the T-shaped elements 3. For this purpose, reinforcement frames are mounted on the columns 1, connecting the stand of the paired T-shaped elements 3 with the strips 4, placing the supports 6 of the base 8 on the foundation or on underlying structures. Between the ends of the shelves 5 of the T-shaped elements 3 and the girders 2, the gaskets 9 are installed, then the frame structure is unloaded by relieving the pre-stress in the reinforcement frame by disconnecting the fasteners 7. The inventory pulls 7 are used repeatedly.

Reinforcement works are not laborious and reduce the time needed to install reinforcement structures in buildings in operation.

METHOD FOR STRENGTHENING THE FRAME DESIGN, including mounting the reinforcement frames, creating prestress in the reinforcement frame, installing pads between the crossbar of the frame structure and the reinforcing frame, and unloading the frame structure, characterized in that, in order to reduce the metal consumption, the reinforcement frames are made in the form of paired T-shaped elements and mounted on columns in the form of cages, and the preliminary voltage of the reinforcement frame is carried out by bending the shelves of the T-shaped element by means of puffs connecting the ends of the shelves to the bottom of the rack and, and after the discharge is performed chocks frame structure prior to deenergization frame gain by disconnecting puffs.
