STRUCTURE FOR JOINING STRUCTURAL MATERIAL MADE OF STEEL FRAME AND THE LIKE, BY HIGH-STRENGTH BOLT

摘要

PROBLEM TO BE SOLVED: To reduce the number of high-strength bolts for use by increasing a frictional force generated at a high-strength bolt friction joint for joining building structural materials made of a steel frame and the like.;SOLUTION: In this joining structure P, a splice plate (S1), which covers joints (L1b) and (L2b) of a pair of base materials (L1) and (L2) astride them, and a frictional sheet material (Q1a), which is positioned between the splice plate and the joint (L1b), are tightened and held in a sandwiched state by the high-strength bolt (U1a). An annular high-strength bolt action area (H1) is formed in such a manner as to share the central axis (C1) of the high-strength bolt (U1a), outside a high-strength bolt tightening force enabling area (G1) which stretches out concentrically from the central axis (C1). The thickness of the frictional sheet material (Q1a) is increased by a dimension (Δd1C) of increased thickness for compensating the deformation of the splice plate, adequate for the filling of a slight amount of joint surface void (g1) formed between the frictional sheet (Q1a) and the splice plate (S1), by the warping of the splice plate (S1) in the area (H1).;COPYRIGHT: (C)2011,JPO&INPIT
