摘要

PROBLEM TO BE SOLVED: To provide the supporting structure of an exterior wall in a wooden building, in which air flow space is formed between the exterior wall and a heat-insulating material, and a wood screw for supporting the exterior wall.;SOLUTION: The heat-insulating material 2, vent furring strips 3 and an exterior wall material 4 are arranged successively outside a plurality of column materials 1, and these material 2, furring strips 3 and material 4 are screwed and clamped by the wood screw 5. In the wood screw 5, an outside screw section 7 is formed by forging, the diameters of the bottom sections 16 of the outside screw section are formed at a value smaller than that of the shaft section of the wood screw, and the outside screw section 7 is buried so as to be completely screwed and bitten into the column material 1.;COPYRIGHT: (C)2002,JPO
