Abstract

PROBLEM TO BE SOLVED: To strengthen and improve the earthquake resistance of an existing house by fitting a reinforcing brace in parallel with an existing brace at the brace portion of the outer wall of the existing wooden house. SOLUTION: One end of a reinforcing brace 1 is fitted to a girth 6 on a first floor portion, and the other end is fitted to a groundsill 7. One end of the reinforcing brace 1 is fitted to the girth 6 on a second floor portion, and the other end is fitted to columns 5a, 5b. Intertruss braces 2a, 2b are fitted in parallel with an existing brace at the center of the reinforcing brace 1, and joint metals 3 are fitted to the connection sections between the reinforcing brace 1 and the intertruss braces 2a, 2b. When an existing wooden house has a single-brace structure, its structure is made equal to a cross-brace structure having two times the yield strength of the single-brace structure. When compressive force is applied to the reinforcing brace 1 from the outside, the deformation of the reinforcing brace 1 can be suppressed.

[Prior Art] Conventionally, the only way to improve the earthquake resistance of wooden houses was to take measures to strengthen the earthquake resistance at the time of new construction.
There is no method for strengthening the earthquake resistance of existing wooden houses, and there was a danger that the building would collapse during a large earthquake.

[Means for Solving the Problem] Reinforcing brace 1 is attached to the outer wall brace portion of an existing wooden house so as to be symmetrical,
At the center of the reinforcement braces 1, the anti-skid braces 2a and 2b were attached so as to be parallel to the existing braces, and the joint metal fitting 3 was attached to the joint between the reinforcement braces 1 and the anti-skid braces 2a and 2b.

Since the present invention has taken the above means, when this construction method is used, one end of the reinforcing braces 1 is attached to the barrel and the other one is attached to the base on the first floor portion. . On the second floor, one end of the reinforcing braces 1 is attached to the barrel and the other end is attached to the columns 5a and 5b. As a result, when the structure of the existing wooden house has one-sided bracing, it is structurally equivalent to the tassel bracing, and the proof strength is twice that of the one-sided bracing. Further, by joining the anti-sway braces 2a and 2b symmetrically to the reinforcing braces with the joint metal fitting 3, the deformation of the reinforcing braces 1 is suppressed when a compressive force acts on the reinforcing braces 2a and 2b from the outside. Work.
