Description

  The present invention relates to a reinforcing hardware used by being fixed to a joint portion between a horizontal member and a vertical member in a wooden house.

  In wooden houses, in order to increase the strength, braces are attached on the diagonals of the frame structure formed by horizontal members and vertical members, such as foundations and pillars or horizontal members and through pillars. In response, many large windows could not be provided.

  Then, as one means for removing the bracing without reducing the strength of the wooden house and providing a large number of wide windows in the wooden house, for example, there is one as shown in FIG. According to this means, a reinforcing metal fitting 82 (see Patent Document 1) comprising an angle member 80 and a connecting member 81 that inclines inside the angle member 80 and joins both ends of the angle member 80 is prepared.

The panel 85 is attached to the frame structure so as to cover the fixed portion of the reinforcing metal fitting 82 with a nail so that a window is provided in a space 88 formed between the two panels 85. It has become. In this way, the frame structure has been reinforced by a combination of the reinforcing bracket 82 and the panel 85 instead of the bracing.

  However, according to this means, all of the nails 83 for fixing the reinforcing hardware are arranged in parallel to the plane surrounded by the frame structure, so that the reinforcement is provided by the deformation of the frame structure caused by the rolling at the time of the earthquake. The nail 83 that fixes the metal fitting 82 to the frame structure is easily detached, the reinforcing metal fitting 82 is easily dropped from the frame structure, and the joined longitudinal member 86 and transverse member 87 are easily separated. That is, this means gives the same strength as the case where the braces are provided at the joint between the vertical members 86 and the cross members 87 forming the frame structure of the wooden house, but the wooden house at the time of the occurrence of the earthquake. It does not take earthquake resistance into account, so this means cannot secure sufficient strength at the joint between the longitudinal members 86 and the transverse members 87 and prevent the collapse of the wooden house when an earthquake occurs. It was.
