ANTI-SEISMIC REINFORCING METHOD AND ASEISMATIC REINFORCEMENT STRUCTURE OF EXISTING WOODEN HOUSE

摘要

PROBLEM TO BE SOLVED: To provide an aseismic reinforcing method and an aseismic reinforcement structure of an existing wooden house which make possible a short construction period and which can obtain earthquake-resistant reinforcement at low cost which has high earthquake-resistant performance.;SOLUTION: A boring which is extended in different directions, namely in the diagonal direction and in the perpendicular direction, is formed in a foundation and base concrete of an existing wooden house, and a base-concrete anchoring member having a male screw part on both ends is inserted to the boring. One end of the base-concrete anchoring member is made a base-concrete inner anchoring part, and the other end is exposed. Then the boring, which is extended in different directions, namely in the diagonal direction and in the perpendicular direction, is formed in a horizontal member such as a beam which is supported by a pillar. A horizontal member anchoring member having a male screw part on both ends is inserted to the boring. One end of the horizontal member anchoring member is made a horizontal-member upper anchoring part, and the other end is exposed. An eyenut to which a high-strength wire member is connected is screwed to the base concrete and the male screw part of the horizontal member anchoring member. Tension is applied to the high-strength wire member through the medium of the base concrete anchoring part and the horizontal-member upper anchoring part. The high-strength wire members which intersect each other diagonally and the vertical high-strength wire members are arranged between the foundation on the base concrete and the horizontal member.;COPYRIGHT: (C)2009,JPO&INPIT
