ASEISMATIC REINFORCE FRAME FOR EXISTING BUILDING, CONSTRUCTED IN CONVENTIONAL WOODEN FRAMEWORK CONSTRUCTION METHOD, BY USING BEARING STEEL FRAME AND BRACING STEEL FRAME FROM OUTSIDE

摘要

PROBLEM TO BE SOLVED: To simplify reinforcement by providing an auxiliary foundation connected to a continuous footing, on the outside of a wall body part to be reinforced of an existing wooden framework building, fixing a steel frame reinforced by bracing and the like, onto the auxiliary foundation, and fastening the steel frame to a building frame. ;SOLUTION: Dimensions between a sill 13 of a bearing wall part and a second floor beam 15 and between columns 14, 14 of an existing building are measured, and a steel frame 1 is manufactured to the measured dimensions in a factory. The frame 1 is provided with a center band frame 2, bracing frames 3, and the like for reinforcement. An auxiliary reinforced concrete beam 10 provided with a steel bearing beam 5 formed of channel steel or the like is installed integrally with an existing continuous footing 9, on the outside of the continuous footing 9. The steel frame 1 is fixed to a building frame by through-bolts 19 or the like from the surface of existing exterior wall material 28, and dry building material is attached thereon for finishing. The existing wooden building can therefore hold earthquake resistance at a low cost without strain.;COPYRIGHT: (C)1999,JPO
