Problems solved by technology

Although the reason for not integrating the reinforced beams with the existing beams is not clearly stated, if the reinforced columns are integrated with the existing columns, the reinforced columns through compounding will improve the earthquake resistance of the building

Embodiment Construction

[0035] Hereinafter, the seismic reinforcement structure of the present invention will be described in detail with reference to the drawings. Applicable buildings are as Figure 11 The shown RC-structure or SRC-structure multi-storey existing buildings illustrate examples in which the front-rear relationship of the respective outer surface positions of the existing columns and existing beams located on the outer wall side are different. figure 2 and Figure 11 Similarly, it is a building 3 in which the existing beam 1 protrudes outward (forward) more than the existing column 2 (towards the outer surface of the external view, refer to the upper left). It goes without saying that the frame 4 is formed by the two existing beams 1 facing up and down and the existing columns 2 facing left and right, so as to form the outer surface of a household or a room of a household.

[0036] The existing beam 1 and the floor 5 are integrated, and although the connection part cannot be seen, th...

Abstract

[Problem] To provide an aseismic reinforcing structure capable of improving the aseismic performance of an existing column without causing a crack in the existing column by a reinforcing column for the existing column and existing beams. [Solution] A reinforcing column (8) is erected at a position outside an existing column (2) located on the building outer wall side of an existing building so as to face the existing column with a space (7) therebetween. The lower portion of the reinforcing column (8) is linked to a reinforcing beam (9L) fastened to an existing beam (1L) integrated with a floor slab (5L). The upper portion of the reinforcing column (8) is linked to a reinforcing beam (9U) fastened to an existing beam (1U) integrated with an upper-floor floor slab (5U). The reinforcing beams (9) fastened to the same existing beam are discontinuous with right and left adjacent reinforcing beams thereof. Even if a difference occurs between the deformation of the reinforcing column and the deformation of the existing column when external force acts, the existing column is little affected by the deformation of the reinforcing column, and hence the occurrence of a crack in the existing column can be reduced to a minimum.

Description

technical field [0001] The present invention relates to an anti-seismic strengthening structure, in particular, to an anti-seismic strengthening structure on the outer surface of multi-storey existing buildings of RC structure and SRC structure. Background technique [0002] Reinforced concrete structures (hereinafter referred to as RC structures) and steel reinforced concrete structures (hereinafter referred to as SRC structures) are used for example Figure 11 The multistory building shown. It goes without saying that the columns and beams are indispensable, and in the frame 33 formed by the columns 31 and beams 32 on the outer wall side, a belly wall / vertical wall, a door, a window (omitted in the figure), etc. are provided. The columns support the load of the upper floor, and the beams are integrated with the floor slabs 34 of each floor. [0003] When such a building is subjected to a large lateral force due to an earthquake or the like, the upper beam in the frame dev...
