Abstract

The invention relates to construction. The purpose of the invention is to increase the stability and improve the conditions of repair work. The building body has a lower part with a curvilinear outline in the vertical plane along the Bernoulli curve and an upper part in the shape of a truncated pyramid. The lower part of the body with the base plate is installed on the bottom of the foundation trough plate through ball bearings. The latter are combined into blocks and placed in the channels in the bottom of the base plate. In the walls of the latter are made through holes, the lower faces of which have projections. The distance between the protrusions and the mark of the bottom face are equal, respectively, to the width of the channels and the bottom mark of the latter. 7 il. . &

Description

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

The purpose of the invention is to increase the stability and improve the conditions of repair work,

FIG. 1 shows a multistory building; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. - section BB in FIG. 3; in fig. 5 shows the node I in FIG. 3; in fig. 6 is a view along arrow G in FIG. five; in fig. 7 is a view along arrow D in FIG. 3

The seismic multi-storey building contains a housing 1 of monolithic reinforced concrete with a base plate 2 installed on the bottom of a foundation-shaped trough plate 3 through ball bearings 4 and connected to its walls 5, 6 by means of dampers 7,

located along the contour of the base plate 2.

The housing 1 is made in height from two parts 8, 9. The lower part 8 has a curvilinear shape in a vertical section along the Bernoulli curve, and the upper part 9 is made in the shape of a truncated pyramid.

The bottom of the base plate 3 is made with channels 10 located parallel to its walls 5 of the same direction. In the walls 6 of the other direction, the through holes 11 coaxial with the channels 10 are made, the lower faces of which have projections 12. The distance between the projections 12 and the lower edge mark are respectively equal to the width and bottom mark of the channels 10. Walls 6 of the foundation plate 3 are fitted with inserts 13, installed in through holes x 11 and attached outside to walls 6, on Qs

for example, strips 14, welded to the inherent, embedded parts m 15 walls 6.

Ball bearings 4 can be made in the form of ball bearings, combined in blocks connecting element 16 with slots 17 and installed in the channels 10 with gaps 18 relative to their walls 19.

Floor covering 20 is made of monolithic reinforced concrete. In the lower three floors, stiffening elements 21 are installed, for example, in the form of walls.

Slats 14 should be insulated, for example, with two layers of hydroisol, followed by a clay lock.

Ball bearing blocks are replaced at the end of their service life. To do this, the trenches are opened near the walls 6 of the foundation plate 3, the strips 14c of the two sides of the channels 10 are removed in the bottom plate by electric welding, then the inserts 13 are removed and the jacks 22 are installed on the bottom of the channels 10 from which the building is raised. Thereafter, blocks of ball bearings are knocked out of channels 10 by any known method, and new ones are inserted, then the building is lowered with jacks 22, the latter are removed and inserts 10 are inserted into the sides,

The composite body of the building allows to increase the stability of the building during horizontal oscillations, since under seismic impacts the building will not deviate from the vertical, and the trace JL 21

of course, there will be no additional load. Ball bearing blocks relieve seismic stress on a building, and dampers absorb seismic energy.
