Abstract

Usage: to restore the verticality and reinforcement of buildings made of reinforced concrete half-frames, mainly for agricultural purposes. SUMMARY OF THE INVENTION: the device includes walls located in the plane of columns of composite half-frames and on the bank side having a vertical end surface, on the side opposite to the bank, has an inclined surface adjacent to the side surface of the tilted column of the half-frame. In the upper part of the inclined surface of the wall, a spacer is installed between it and the column. 2 C.p. fs, 4 ill.

Description

The invention relates to the construction, in particular, to the restoration of verticality and reinforcement of buildings constructed from reinforced concrete half-frames and having predominantly agricultural purposes.

The purpose of the invention is to eliminate the roll and reinforce the building with the restored vertical position of the half-racks.

Fig. 1 shows a building with installed buttresses; the roof of the building is not shown conditionally; figure 2 is the same, cross section; in Fig. 3 - buttress with an inclined position half-frames; Fig. 4 is a buttress after removal of a roll.

Example. The agricultural building was erected from reinforced concrete half-frames, consisting of & racks 1 and crossbars 2. Racks 1 are supported by prefabricated foundations 3. As a result of the absence or removal of static connections from the wind connections, the half-frames of the entire building are tilted. Surveys have shown that tilted half frames remain parallel to each other. The device for reinforcing the building of the invention includes buttresses 4, which are located in the plane of the half-frame racks and are supported by strip foundations not shown in the drawing.

Each buttress on the side of the roll has a vertical end surface 5, on the side opposite the roll - an inclined side surface 6. In the upper part of the inclined end surface there is a spacer, for example a wedge or a jack. As a result of the spacer, the racks 1 of the half-frames are given a vertical position. In this case, the posts 1 are pressed against the vertical end surface 5. The gap between the inclined end surface 6 of the buttress 4 and the rack 1 is monolithic with concrete or filled with masonry 8.

The sequence of operations to restore verticality and strengthening the building using the invention:

(L

WITH

4 Yu Yu Yu h |

the buttresses of the buttresses are erected and the nests in the foundations around the supporting parts of the uprights are cleared of half-frames;

buttresses are erected from brick or rubble stone on strip foundations;

after the masonry has reached the required strength, the racks of the half-frames are brought upright;

the gaps between the inclined end surfaces of the buttresses and the struts are half-monoformed;

if necessary, open-type buildings can be converted into a closed room, for this, window blocks are installed over the buttresses and masonry is carried out to the full height of the half-racks. ..

Claims (3)

The claims 1, A device for reinforcing a building, including reinforced concrete frames and longitudinal reinforcement elements located between the columns, characterized in that, in order to increase the reinforcement efficiency in the presence of a building roll, the frames are made of two half-frames, while the reinforcement elements are located in the plane of the columns and are made in the form of walls with a vertical end surface on one side and an inclined end surface from the side of the roll formation of the column of the half-frame, with a spacer installed between the inclined surface in its upper part and the column, and the length of the wall and level 5 bottom and the columns of half-frames are equal to the distance in the light between the columns of neighboring pipurams. . 2. Device pop. 1, characterized in that the spacer is made in the form of a jack. 3. The device according to claim 1, with the exception that the spacer is made in the form of wedges. 0 FIG. 2 F "p 4
