The invention relates to the field of construction, namely, the strengthening and reconstruction of existing buildings and structures.

Known design to enhance the building during its reconstruction, in which is described a method of reconstruction of a building or structure by strengthening the cores including installation inside a building or construction cores for the perception of load bearing elements of the frame of a building or structure (see patent RU 114701, class E04G 23/02, published on 10.04.2012,).

The disadvantage of the described invention is the absence of structures to transfer loads from existing elements of the frame of the building erected on a reinforced concrete structural core and method of the described structures.

The present invention is the task to redistribute loads inside the building, from the damaged items on the constructed kernel hardness, to increase stability, improve the earthquake resistance of a building or structure, to optimize material costs during the reconstruction of a building or structure in any weather conditions, to reduce the stopping period of reconstruction.

The problem is solved in that the method of reconstruction of a building or structure, including installation inside a building or construction cores for the perception of load from chosen to replace the elements of a skeleton of a building or structure, characterized in that the structural core set with a gap with respect to the amplified spans the construction of floors, which are mounted bearing farm, fix them in the cores to a depth of not less than half the thickness of the respective structural core perpendicular to the latest and still bind with adjacent structure, made in the form of girders and beams, or girders, or slabs, with the ends of the trusses zamonolichivajut in kernel hardness.

Because of the structural core set with a gap with respect to the amplified spans the construction of floors, which are mounted bearing farm, fix them in the cores to a depth of not less than half the thickness of the respective structural core perpendicular to the latest and still bind with adjacent structure, made in the form of girders and beams, or girders, or slabs, with the ends of the trusses zamonolichivajut in kernel hardness, redistributed loads inside the building, from the damaged items on the constructed kernel hardness, resistance and seismic resistance of a building or structure, optimized material costs during the reconstruction of a building or structure in any weather conditions, reduced stopping the production period of reconstruction.

In Fig.1 shows the reconstructed building with embedded kernel hardness and carrying farm; in Fig.2 - node connection (crushing) reinforced concrete structural core and trusses.

The invention is illustrated by drawings, where Fig.1 schematically shows the structure core 1 inside the reconstructed building when implemented method includes installation under the stairs in the level of interfloor overlappings 4 trusses 2, fixed in a specific position in the level of interfloor overlappings 4. The ends of the trusses 2 then embedded perpendicular to the cores of 1 to a length not more than half the thickness of the respective structural core 1 and sesamine bonded to adjacent structure in the form of girders 3 and 4 floors or girders 3, or 4 floors. During the construction of the cores of 1 it is placed with a gap to span structures in the form of girders 3 and 4 floors or girders 3, or 4 floors and columns 6. Between the vertical load-bearing and non-load-bearing elements of a building or structure under the load-bearing farm install temporary struts 5.

In Fig.2 schematically shows a node supporting farms 2 on the wall of the structural core 1, where the ends of the trusses 2 then embedded in the core hardness 1.

Reconstruction of a building or structure by strengthening the cores produced as follows.

With the technical and engineering-geological surveys determine the carrying capacity, the physical deterioration of existing load-bearing elements of a skeleton of a building or structure, the geological structure of the soil Foundation and their carrying capacity, and then make recommendations for the reconstruction or restoration. According to the recommendations of the designated locations for cores 1 in the most damaged or weakened areas of the building. Under the stairs in the level of interfloor overlappings 4 bearing down farm 2. At a given level record additional bearing elements farms 2 to a predetermined position and after the location of their erect structural core 1 with a gap to span structures. At the level of intermediate floors 4 to the cores 1 and perpendicular pinched attach supporting farm 2, with the ends of the trusses 2 then embedded in the cores of 1 to a length not more than half the thickness of the respective structural core 1. In addition, carrying farm 2 is rigidly connected with the adjacent structure in the form of girders 3 and 4 floors or girders 3, or 4 floors. When erecting structural core 1 is fitted with a gap to span structures. After a set of concrete, which is made from structural core 1, the design bearing strength of the farm 2 is released from the temporary props 5.

Because of the structural core 1 are reconstructed inside the building, through the established carrying farm 2 they take the load from the damaged frame elements: beams 3, columns 6 and 4 floors. F is damenti 7 cores 1, based on reliable soil reaction support is not less than the total estimated load from a building or structure, increase stability and seismic stability of the reconstructed building or structure.

The technical result provided by the method of reconstruction of a building or structure is to improve stability and seismic stability of the building, optimizing material costs during the reconstruction of a building or structure in any weather conditions, reducing the stopping period of reconstruction.
