Description

  The present invention relates to a seismic reinforcement structure for buildings and a seismic reinforcement method for buildings.

  In wooden houses, especially when they are old, the earthquake resistance is often insufficient, and there is a risk of collapse in the event of a strong earthquake. As a method of improving the seismic strength, a method of fixing a reinforcing material such as a plywood or a metal fitting to increase the strength on the wall or pillar, or a method of attaching a brace to the wall is conceivable. However, in the conventional seismic reinforcement method, the construction is large and expensive, and if the window is provided on a wall that requires earthquake resistance, sufficient reinforcement cannot be performed or the window needs to be closed. There were problems such as the need to dislodge residents and the inability to expect a high seismic effect on costs. On the other hand, Patent Document 1 proposes a seismic method for a wooden house that is simple and can be used while being in a room. In the earthquake resistance method of a wooden house of Patent Document 1, in a two-story wooden house, it is configured to support a wooden trunk difference portion of the second-floor floor outer peripheral position with a pole erected with the lower end buried in the ground. Is made to stand upright on the ground and is tightly coupled to the wooden barrel difference through through bolts provided with a plurality of connecting members made of plate materials or angle materials at appropriate intervals.
