    • PROBLEM TO BE SOLVED: To improve workability of temporary work by using raw material of high strength equal to or more than prescribed strength, and making a thin steel tube equal to or less than prescribed thickness a temporary steel tube. SOLUTION: High strength carbon steel material whose Mn content is about 1.5-2.5wt.% and tensile strength is about 900N/mm or less is used as raw material for constituting a steel tube, and a thin steel tube of thickness of 1.5mm or less is made therefrom. The steel tube body 1 is formed as a rectangular square steel tube, and molten zinc galvanizing or Al-Mn alloy plating is performed on the inside and outside surface of the steel tube as corrosion prevention processing. Thus the steel tube has necessary strength as a temporarily set steel tube, and its weight is lightweight. Thereby working burden of temporary work workers is reduced, workability and safety are improved and material and transport costs can be reduced.

    • PROBLEM TO BE SOLVED: To provide an installation device that is capable of keeping a holding washer upright constantly with directional adjustment at the flat part formed at a conventional shaft body being unnecessary, and works as required in conventional methods for lifting the holding washer on shifting to fastening of a batter is not required by adding a simple structure. SOLUTION: A batter installation device 1 for form for concrete placing is composed of a shaft body 2 having a connecting screw part 8 for connecting with a separator at its front end and a holding part 4 at its rear end and a holding washer 3 with fastening projections 12 and 13 formed at positions opposite to a contact part 11 for contacting with walers 9 and 10, and a fastening handle 5 interposed between the holding washer 3 and the holding part 4. A cylindrical sliding part that is fitted in back-and-forth sliding to the shaft body 2 is formed on a part where the holding washer 3 is loose-fitted to the shaft body 2, and the holding washer is kept upright against the shaft body 2 by sliding contact made between the cylindrical sliding part and the shaft body 2.

    • PURPOSE:To prevent a cap from falling off and corrosion due to entry of moisture by forming it with a soft packing part of U-shape in cross-section and a composite material of hard part covering an outer surface, and strongly pressing it into the butt end of an end surface using a strong pressing force so as to strongly press it and strengthen the connecting condition. CONSTITUTION:The soft packing part 3 of generally U-shape in cross-section and the outer surface of the packing part 3 of an end surface cap 2 are covered with a hard part 4 of U-shape in cross-section. Also the soft packing part 3 is fitted closely into the butt end of the end part of a steel pipe 1. Then the hard part 4 is pressed into the soft packing part 3, or the hard part 4 is assembled into the packing part 3 beforehand and then pressed into the butt end of the steel pipe 1. In addition, the packing part 3 presses strongly between the hard part 4 and the internal surface of the steel pipe 1 so as to form them integrally. Thus the sealing property with the steel pipe 1 can be increased remarkably to prevent the cap from falling off and reduce noise occurred from the steel pipe 1.

    • PROBLEM TO BE SOLVED: To realize the lighter weight of a pipe support, facilitate the inserting worn or a, support pin to improve the assembling and disassembling work and the moving and carrying work, and reduce the excessive labor. SOLUTION: The insert pipe 2 and waist pipe 3 of a pipe support 1 are formed of square pipes. The insert pipe 2 has a rib 2a protruded on the inner surface, and a guide pipe 7 is mounted on a pin hole across the pipe body. These also function as reinforcing members. A screw pipe 8 fixed to the pipe body upper part of the waist pipe 3 has an oblong hole 8b, through which a support pin 10 is inserted. The direction of the insert pipe 2 is selected so that the oblong hole 8b and the pin hole are situated on the same straight line. Since the square pipe has a high cross sectional performance, compared with a round pipe of the same material, the lighter weight can be realized, and the support pin inserting work is facilitated by the guide pipe 7.
