STAY RAFTER AND CEILING COMMON JOINT FASTENING METAL FITTINGS FOR 2X4 CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To improve workability and quality by integratedly forming a vertical member mounting part, head connection mounting part, and rafter and ceiling common joint mounting part through connection parts. ;SOLUTION: A vertical member mounting part 1, head connection mounting parts 2, 3 and rafter and ceiling common joint mounting parts 4, 5 are formed of one sheet of steel plate in a shape shown by the Fig. and integrated by connection pats 6, 7, and further a nail hole is formed in each part, thereby constituting metal fittings for fastening. Upon execution of work, the metal fittings is mounted to a vertical member, then the ceiling common joint is mounted, and the rafter is mounted thereon. In this case, when the connection part is bent and overlapped, adjustment is made possible to the width when the ceiling common joint and the rafter are in one piece and two pieces in number. Accordingly, the ceiling common joint and the rafter can be fastened to a rafter and ceiling common joint mounting part by driving a nail from the lateral direction, and the reafter and the ceiling common joint can be fixed on a straight line, thereby enabling elimination of cogging at a horizontal part of the ceiling common joint, and enabling the construction of stay of roof rafter and fastening of the rafter and the ceiling common joint with one piece of fastening metal fittings.;COPYRIGHT: (C)1999,JPO
