/ I phi1.1 1 The invention relates to the construction and is intended for the construction of earthquake-resistant buildings, on the walls of which natural stone is spent. A multi-storey building is known, including precast reinforced concrete silt steel frame, formed by columns and girders, floor slabs supported on girders, and wall filling of small stones fl. The disadvantages of this building include the separation of load-bearing and enclosing pounds between the frame and masonry. In addition, it has an increased consumption of steel on the frame elements and high labor costs for maintenance. The closest technical solution to the invention is a multi-storey earthquake-resistant building, which includes monolithic reinforced concrete columns, horizontal linear elements rigidly connected to the columns by means of reinforcement of floor slabs supported on linear elements, and a wall enclosure made in the form of masonry of small C2 stones. The disadvantages of this building are the increased complexity of the construction, due to the manual process of laying the walls and the monolithic frame and the considerable consumption of the walls, resulting in a high seismic load on it. The purpose of the invention is to increase seismic resistance and reduce labor intensity. This goal is achieved by the fact that in a multi-storey seismic resistant building that includes monolithic reinforced concrete columns, horizontal linear elements rigidly connected to the column by means of reinforcement plates, supported on linear elements, and wall fencing made in as a masonry of small stones, masonry wall fencing is made in the form of panels crimped by the upper and lower horizontal linear elements, while the wall enclosure s external and internal supporting walls formed of panels placed with a gap therebetween, and slabs zaschemlenymezhdu Jshneynymi adjustment elements adjacent panels. Figure 1 shows the building plan; figure 2 - section aa in figure 1; fig.Z - node 1. figure 1; Fig. 35 is the same, the embodiment; in Fig.5 section bB in Fig.1; figure 6 - section bb In figure 1. The multi-storey earthquake-resistant building includes monolithic reinforced concrete columns 1, floor slabs 2 and wall fencing 3, made in the form of panels 4 from masonry 5, crimped by upper and lower horizontal linear elements 6, fitted at the ends with reinforcement releases 7 for rigid connection of panels 4 with columns 1. The outer walls 8 and the inner bearing walls 9 are formed from two panels 4 installed with a gap of 10 between them. The floor plates 2 are clamped only between the linear reinforced concrete elements 6 of the panels 4 adjacent in height, due to which a fundamentally new co-constructive solution to the junction of the outer wall - the overlap characterized by increased tightness is formed. Each upper linear reinforced concrete element 6 of panel 4 is rigidly connected to the lower linear reinforced concrete; 1 with a bar 6 of the upper-lying panel 4, forming a bolt, i.e. By connecting the embedded parts, an integral element of the framework is formed by a bolt of a tie bar, which has no analogues in construction practice in seismic areas. The erected outer wall 8 forms, as it were, the outer part of the wall, bearing and perceiving its own weight, within the volume bounded by this wall, the second part erected, having linear elements 6 in the level of each floor, on which the slabs 2 are supported, in other words, around the erected building additional clip. Due to the gap 10 between the panels 4, it is possible to create barriers that meet the most demanding thermal requirements. The interconnected outer and inner panels 4 in certain places in height allow you to successfully perceive and redistribute seismic loads. Installing panels 4 with a gap of 10 between them improves not only the thermal performance, but also reduces the mass of the building and thereby increases its seismic resistance.

The building is erected as follows.

Within each floor, it is first installed in the design of the panel 4 of the transverse walls 11, the inner longitudinal curtain 9 and the inner part of the outer walls 8. With the help of the inventory fixtures, the panels 4 are secured against falling. Floor slabs 2 are mounted. Then, with a gap of 10, panels 4 of the outer part of the supporting longitudinal walls 8 are installed. The width of the gap 10 between the panels 4 is determined by heat engineering calculation. Using embedded parts 12 combine the linear elements 6 in the level of the overlap, forming a bolt. The reinforcement 13 of the monolithic columns 1 is installed, the formwork panels 14 are fixed, and between the panels 4 of the outer walls 8, inventory pads are installed at the side faces to prevent concrete from flowing into the gap 10. Armstorm outlets 7 from the ends of the linear reinforced concrete elements 6 are crushed during concrete pouring of the columns 1 .

When moving to the upper floor, the process technician repeats.

. Such a constructive construction of the building improves its strength characteristics, reduces the mass of the walls by up to 30% and thereby reduces the seismic load on the building, thereby increasing its seismic resistance. The clamping of the overlap between the linear elements 6 of the panels 4 allows the vertical and seismic loads to be redistributed between the adjoining walls and creates the most favorable conditions for the operation of the building.

Replacing masonry from piece elements with panels, and monolithic bolts with linear reinforced concrete elements with which the panels are provided, ensures the industrial construction of a multi-storey building, reduces construction time, reduces labor costs for building walls by 40-50%. The steel consumption on the frame is reduced by 5-7 kg / m of the total reduced area of the building.
