摘要： PROBLEM TO BE SOLVED: To provide a connecting device capable of jointing principal members together accurately and strongly in wooden structures and also capable of disconnect the connections without damaging the main principal members. SOLUTION: A joint member 2 is fixed to one member (column 17) to be jointed, a slit 22 is formed to another member (beam 18), the slit 22 is fitted to the joint member 2 with the slit 22 aligned, and a pin 3 from other member is penetrated and inserted to the other member and the joint member 2. Pin 3 has spiral projected stripes 14 on the outer periphery, and when it is rotated, the spiral projected stripes 14 move forward by linking with end edge 30 of installing holes 8, 9 provided at the jointing member 2, and a state wherein the pin 3 is inserted occurs. When the pin 3 is pulled out, jointing between one member and other member can be released.

摘要： PROBLEM TO BE SOLVED: To cope with blowing up force and suction force and to prevent rafter tumble during an execution by bending a dies cutting iron plate and forming four surface parts for fixing and reinforcing a rafter side surface and upper surface and side surface of a horizontal frame material. SOLUTION: A rafter locking fitting 3 for galvanized sheet iron press molding product is constituted of a first surface part 4 for fixing a side surface of a rafter 1, second and third surface parts 5, 6 for fixing an upper surface and a side surface of a horizontal frame material 2 and a fourth surface part 7. The first and fourth surface parts 4, 7 and second and third surface parts 5, 6 are formed into long and narrow trapezoidal shapes and rectangular shapes, respectively by bending an iron plate at a right angle after dies cutting of the plate. The first and second surface arts 4, 5 and the third surface part 6 are provided with two holes for fixing and one hole for fixing, respectively, and are fixed to the rafter 1 and the horizontal frame material 2 with machine screws. By fixing force of the first, second and third surface part 4, 5, 6 and reinforcement of the fourth surface part 7, blowing up force B, suction force C, component force A of roof weighting and rafter tumble D are restrained. As a result, blowing up by wind and also rafter tumble during an execution can be prevented.
