Bearing wall of wooden house

Abstract

A bearing wall partitions into a plurality of openings and in a vertical direction between adjacent column members by bridging a beam member that serves as a window sill between intermediate portions of the adjacent column members in a framework. Both end portions of the beam member are tied to intermediate portions of the adjacent column members via metal joints. A window is installed in the upper opening, and a peripheral end portion of the structural plywood is fixed to the lower opening with a nail. The structural plywood is fixed with nails at a rough nail pitch.

1 . A bearing wall ( 1 ) of a wooden house partitioned into a plurality of openings ( 13 ) and ( 14 ) in a vertical direction between adjacent column members ( 3 ) by bridging at least one beam member ( 11 ) that serves as a window lintel or a window sill between intermediate portions of the adjacent column members ( 3 ) in a framework ( 2 ) of the wooden house, the bearing wall having a structural plywood ( 50 ) stuck onto an opening ( 14 ) other than a window installation opening ( 13 ) among the openings ( 13 ) and ( 14 ), wherein both end portions of the beam member ( 11 ) are tied to intermediate portions of the adjacent column members ( 3 ) via metal joints ( 20 ), and a peripheral end portion of the structural plywood ( 50 ) is fixed to the opening ( 14 ) with a nail or a screw. 
     
     
         2 . The bearing wall of a wooden house according to  claim 1 , wherein the beam member ( 11 ) has a beam height of 150 mm and a beam width of 120 mm. 
     
     
         3 . The bearing wall of a wooden house according to  claim 2 , wherein a peripheral end portion of the structural plywood ( 50 ) is fixed to the opening ( 14 ) with nails or screws by driving nails or screws at a ratio of nine nails or screws per 1 m along a peripheral end portion of the structural plywood ( 50 ). 
     
     
         4 . The bearing wall of a wooden house according to  claim 3 , wherein horizontal frame members ( 10 ) and ( 12 ) having a cross-sectional area smaller than a cross-sectional area of the beam member ( 11 ) are bridged between upper end portions or lower end portions of the adjacent column members ( 3 ), so that the horizontal frame members ( 10 ) and ( 12 ) serve as a base for installing a window ( 40 ) or fixing the structural plywood ( 50 ) with nails or screws.
