Description

The invention relates to the construction and can be used in the construction of large-panel buildings in seismic areas.

A large-panel seismic building is known containing precast reinforced concrete panels of external and internal walls with reinforcing loop outlets at the ends, floor slabs and connecting elements for fastening the panels and slabs to each other.

The closest technical solution is a large-panel earthquake-resistant building, including prefabricated reinforced concrete panels of external and internal walls with reinforcing outlets in their corner cutouts, floor slabs with embedded parts and connecting elements, in the form of reinforcing bars placed in vertical seams of exterior wall panels along the height of the building, and located in the corner cutouts of the wall panels, horizontal plates, one part of which is attached to the reinforcing outlets of the panels of the adjacent external and internal walls and without he embedment.

A disadvantage of the known solutions is the lack of stability of buildings during seismic and emergency impacts.

The aim of the invention is to increase the stability of the building during seismic and emergency impacts.

The specified goal is achieved by gem, that the building is equipped with additional connecting elements in the form of rolled sections, mounted vertically in the seams of the panels of the external walls in the area of floor slabs and rigidly connected to reinforcing bars and outlets of wall panels and horizontal plates, the other part of which is attached to the mortgages details of floor slabs.

Figure 1 shows a cross section of a large-panel building; figure 2 is a fragment of a longitudinal section of a large-panel building; in Fig.3 - the connection node of the panels of the external and internal walls with the slab (axonometry); figure 4 is the same, cross section; figure 5 is the same, longitudinal section.

A large-panel earthquake-resistant building contains prefabricated reinforced concrete panels of the outer 1 and inner 2 walls with reinforcing outlets 3 in the corner cutouts 4,5, floor slabs 6 with embedded parts 7 and connecting elements in the form of reinforcing bars 8 placed in vertical seams 9 of the outer wall panels 1 by the height of the building, horizontal plates 10 located in the corner cutouts of 4.5 panels of 1.2 walls and concrete monolithic 11.

The building is equipped with additional connecting elements in the form of segments of the rolling profile 12, which are installed in the seams of the panels of the outer walls 1 in the area of the floor slabs 6 and are rigidly connected to the reinforcing bars 8 and the outlets 4 of the panels of 1.2 walls.

One part of the plates 10 is attached at one end to the reinforcement outlets 3 of the panels of the outer 1 and inner 2 walls, the other part is attached to the embedded parts 7 of the floor slabs 6, and all the plates 10 are attached at the other end to the length of the rolling profile 12.

In the foundation 13 in the places where the base panels 1,2 are mated, the sections of the rolling profiles 12 (for example, in the form of a channel) are closed with the shelves outward. Then, the profiles 12 are connected to the reinforcement of the foundation 13 and monolithic. Next, basement panels 1 of the inner walls 2 of the basement are mounted, which include the rolling profiles 12. Using horizontal plates 10, the rolled profiles 12 are welded to the reinforcing outlets 3 of the lower part of the panels 1,2, and the vertical rods 8 are welded to the profiles 12 and to them, in turn, welded sections of the rolling profiles 12. The welded profiles 12 are connected to the outlets 3 of the upper part of the panels 1,2 using plates 10. After that, the floor slabs 6 are laid and the horizontal plates 10 are welded to its embedded parts 7, last then, zamonolichivayut concrete joints 11. Further, the panel 1 is mounted, exterior wall panels and interior wall 2 of the first floor. In the resulting seams 9 vertical joints fall segments of the rolling profiles 12, which are attached using horizontal plates 10 to the outlets 3 of the lower part of the panels 1,2. Further, to the elements 12 are attached vertical rods 8, and to them the following elements 12, which, in turn, are connected to the outlets of the upper part of the wall panels 1,2. After that, they install slabs 5 of ceilings 6 of the first floor, embedded parts 7 of which are horizontally connected with plate 10 to element 12 and the joints are monolithic with concrete 11. Next, the process is repeated.

Thus, the spatial bearing system of the building is formed, perceiving seismic influences in any direction.
