COLLAPSE PREVENTIVE STRUCTURE OF WOODEN BUILDING

摘要

PROBLEM TO BE SOLVED: To prevent the collapse of a wooden house by avoiding separation between a foundation and a building in the upper section of the foundation even when a right-under type great earthquake is generated. ;SOLUTION: A sill beam material 3 is built and arranged onto a foundation 2, the sill beam material 3 is clamped and connected to the foundation 2 through anchor bolts 4, and a framework structure 1 is constituted of a through strut 5 joining the sill beam material 3 and a girder material 6 in a framework shape, a girth 7 horizontally bridged at approximately the center of the through strut 5 in the framework shape, supports 8 linking each section between the sill beam material 3 and the girth 7 and between the girth 7 and the girder material 6 in the framework shape, and wooden bracings 9 installed in an oblique shape while being crossed among the framework supporting points of each adjacent support. Braces 11 reinforcing the wooden bracings 9 are disposed in the same-surface housing manner along side faces in the longitudinal directions of the wooden bracings 9, and both ends of the braces 11 are fixed among the framework supporting points of each support. Anchor bolts 12 being penetrated to the girth 7 along both upper and lower supports 8 through the through strut 5 and the girth 7, directly coupling the foundation 2 and the girder material 6 and being used for connecting the foundation and the girder material and anchor bolts 13 joining the supports 8 in the lower section of the girth 7, in which the wooden bracings 9 are crossed in the framework shape, and the foundation 2 and used for connecting the foundation and the supports are mounted.;COPYRIGHT: (C)1997,JPO
