"CLOSE CONNECTION OF TENON AND FIXING DEVICE-2 THEREFOR" WITH CAM AS MAIN FUNCTION

PROBLEM TO BE SOLVED: To provide a connecting method for easily adopting a large scale wooden building to Building Standard Law, eliminating the need of skilled techniques, reducing metallic material connection and facilitating the recycle of materials.SOLUTION: A "tenon connecting and fixing device" includes a through-hole for cylindrical body insertion communicated with a tenon part of a "base material with a tenon" 1 and a "base material with a mortise" 2. A cylindrical body 6 and a thick layer 6-3 on the upper center surface of the inside are provided, and a cam shaft 8 where a wrench insertion margin 8-2 is holed is stored in a holed cavity part 6-2 of a circular cross section. An opening is provided on a surface opposite to the thick layer 6-3 of the cylindrical body 6, the cylindrical body 6 storing the cam shaft 8 is inserted to the through-holes 3, 4 for the cylindrical body insertion operated on the base material, the cam shaft 8 is rotated for about 90 degrees to the position of a stopper 6-3, a piece 7 is pushed out, and thus the "base material with a tenon" 1 and the "base material with a mortise" 2 are drawn and connected.
