CONNECTING STRUCTURE OF WOODEN BUILDING AND REINFORCING STRUCTURE OF WOODEN BUILDING USING IT AND REINFORCING STRUCTURE FORMING CONSTRUCTION METHOD OF WOODEN BUILDING

摘要

PROBLEM TO BE SOLVED: To prevent loosening by drying contraction and vibration, and improve aseismatic performance by inserting a connecting shaft into wood in which a through hole is arranged, and fastening a coil spring arranged between washers by a washer and a nut so as to become a sufficiently compressed condition. ;SOLUTION: A fixed shaft 6 where a slipping-out preventive plate 7 is arranged on the lower end, is inserted into a vertical inserting hole 5 arranged in a sill 3, and a coil spring 15 arranged between a washer 13 and a washer 16 is fastened by a fastening nut 17 so as to become a sufficiently compressed condition. A connecting nut 22 is screw-fitted to a screw shaft 12 part projecting to an upper part of the fastening nut 17, and the fixed shaft 6 and a connecting shaft 21 are put in a connected condition. A washer and a nut are arranged on an under surface of an inserting hole 20, and the coil spring 15 arranged between the upper surface side two washers is fastened by the fastening nut 17 so as to become a sufficiently compressed condition, and the connecting shaft 21 is connected to a beam material 2a. Similarly hereafter, a beam material 2b is connected to the connecting shaft 21. Therefore, even when wood causes drying contraction or the like, looseness of the nut can be prevented. Therefore, durability to seismic force can be improved.;COPYRIGHT: (C)1997,JPO
