PROBLEM TO BE SOLVED: To provide an L-shaped angle attaching implement which improves workability while having the function of adjusting the length of an L-shaped angle. SOLUTION: The L-shaped angle attaching implement 1 includes: a first sandwiching portion A into which an end of a first long piece S1 of the L-shaped angle 2 is to be inserted and which sandwiches the end of the first long piece S1; a second sandwiching portion B which is arranged orthogonally to the first sandwiching portion A, into which an end of a second long piece S2 of the L-shaped angle 2 is to be inserted and which sandwiches the end of the second long piece S2; and an attachment portion C which is fixed by abutting on skeleton concrete. The first sandwiching portion A includes: a first inside sandwiching portion 3 which is pressed against the inner surface of the first long piece S1; and a first outside sandwiching portion 4 pressed against the outer surface of the first long piece S1. The second sandwiching portion B includes: a second inside sandwiching portion 11 which is pressed against the inner surface of the second long piece S2; and a second outside sandwiching portion 12 pressed against the outer surface of the second long piece S2.

PROBLEM TO BE SOLVED: To provide ring steel for a building structure, which can achieve a weight reduction while maintaining a welding strength. SOLUTION: The ring steel 1 for the building structure includes a welding storage part 20 and welding holes 1c. The welding storage part 20 is formed between the inner peripheral part 1a and the outer peripheral part 1b as a groove which has a concave cross section and is shaped like a ring. The welding holes 1c are formed on the undersurface 20a of the welding storage part 20 at regular spacings. As a result of the formation of the ring-shaped welding storage part 20, ring-shaped flanges 21, 22 are formed between the welding storage part 20 and the inner peripheral part 1a and between the welding storage part 20 and the outer peripheral part 1b respectively from the outward appearances of the ring steel 1. Then the circumference of the excess metal part B of a welded part 3 which has been plug-welded in the welding hole 1c reaches the undersurface 20a of the welding storage part 20.

PROBLEM TO BE SOLVED: To provide an implement for mounting a wall panel, which enables a cutting blade of a screw to be surely aligned with the insertion hole of a sandwich portion of a mounting bracket, without breaking the screw in the mounting of the wall panel. SOLUTION: This implement for mounting the wall panel is used to mount an ALC panel 1 to substrate brackets 7A and 7B which are fixed to a structural skeleton 3. The implement for mounting the wall panel includes: zigzag plates 19A and 19B which comprises a panel mounting portion 19b for being bolted to the ALC panel 1, and a sandwich portion 19c for sandwiching the substrate brackets 7A and 7B between itself and the ALC panel 1; and the screw 40 which comprises the cutting blade 41 inserted into the insertion hole 19e provided in the sandwich portion 19c and having a prepared hole formed in the substrate brackets 7A and 7B, and a threaded portion 27 screwed into the substrate brackets 7A and 7B. The diameter A of the threaded portion 27 of the screw 40 is set approximately equal to that B of the insertion hole 19e. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a double pipe type steel pipe pile for vibration isolation which can rotate and press-fit an inner pipe and an outer pipe at the same time while maintaining a space formed of the pipes by devising an engaging structure between the inner pipe, the outer pipe, and a cap covering the inner pipe and greatly contributes to the shortening of a construction period and the reduction of cost, and a construction method of the steel pipe pile. SOLUTION: The double pipe type steel pipe pile for vibration isolation includes the inner pipe 1 provided with a closed-end cylindrical cover 4 into which the lower end of the outer pipe 2 is fitted in the vicinity of the lower end thereof, the outer tube 2 whose lower end is fitted into the closed-end cylindrical cover 4 and which is positioned concentric with the inner tube 1, and a cylindrical part 5 fitted into a space of the upper end formed by the inner pipe 1 and the outer pipe 2 and having a ring 6, contacting with the upper surface of the outer pipe 2 on the outer peripheral surface, and comprises the cap 3 for covering the upper surface of the inner pipe 1. The inner pipe 1 is rotation-transmittably fitted to the cap 3, and the outer pipe 2 is rotation-transmittably fitted to the inner pipe 1. COPYRIGHT: (C)2011,JPO&INPIT
