摘要： PURPOSE: To easily and efficiently assemble reinforcing bar cages and to lessen the operator's labor required for assembly. CONSTITUTION: This device is provided with a supporting body 30A movably on rails 10, 10 and is provided with a supporting body 30B movably on rails 20, 20. The respective supporting bodies 30A, 30B are respectively provided with supporting rods 32, 33 to be placed with main bars across these rods. Rails 40, 40 parallel with the rails 10, 20 are movably provided thereon with moving holders 50. Holding grooves 51 which hold the sheared reinforcing bars in an upright state by insertion of the bottom ends of the sheared reinforcing bars therein are formed on these moving holders 50.

摘要： PURPOSE: To perform engagement of shear cut reinforcing bars without rectifying their end surfaces by a power tool such as a grinder and the like by making a joint harder than the reinforcing bars and providing a tapered part extended outside in the inlet inner surface of the joint. CONSTITUTION: The end surface 21 of a shear cut screw reinforcing bar 20 has a hanging part 22 entering the inside of one side of a diameter direction and a burr 23 protruding to the outside of the other side. Since the screw thread 11 of the inlet of a joint 10 is rolled to be lower, the end surface of the reinforcing bar 20 is slightly inserted into the entrance. The burr 23 of the end surface of the reinforcing bar 20 inserted into the entrance of the joint 10 is brought into contact with the tapered surface 13 of the joint 10. Then, by rotating either one of the reinforcing bar 20 and the joint 10, the burr 23 and the tapered surface 13 are shifted from each other. Since the tapered surface 13 is harder than the burr 23, the burr 23 is either rubbed out or crushed to be eliminated. When the burr 23 of the end surface 21 is thus rectified, the screw joint 24 of the reinforcing bar 20 is fitted in a screw groove 12.

摘要： PURPOSE: To execute a connecting work of a threaded bar by means of a thread type joint without lock nut by one operator. CONSTITUTION: A threaded bar threadedly engaged with a joint and the joint are temporarily fastened and fixed together by means of a jig. The main body 10 of the jig is a shaft-shaped metal fitting of U-like cross section, and the inner circumferential face 11 is provided with a semi-columnar face 16 and two planes 17 extending in parallel from both side edges of the semi-columnar face to the outer circumferential face 12 of the main body 10 and forming an opening 15. A thread groove 14 threadedly engaged with the maximum height side of the thread of the threaded bar is carvedly provided in the inner circumferential face 11. The diameter of the semi-columnar face 16, namely, the width of the opening 15 is formed to be equal to the short diameter of thread of the threaded bar, or a little larger than it.

摘要： PURPOSE:To improve the productivity and to reduce the cost by manufacturing a joint screw reinforced steel. CONSTITUTION:A screwed projection is formed in a working part 11 of a core metal. The working part 11 is loosely inserted into a through-hole 21 in a base stock 20 and this is set to a lower die 31 in a pressing device. The base stock 20 is plastically deformed by pressing with the lower die 3 and an upper die 32 to form the cross sectional shape in the outer peripheral surface of the base stock 20 to a hexagon. At the same time, the inner peripheral surface of the through-hole 21 is brought into pressurized contact with the outer peripheral surface of the working part 11 to form a screwed groove on the inner peripheral surface of the through-hole 21. This base stock 20 is laid on a table 41 in the other pressing device, and by pressing with a hammer 42, a gap 50 is formed between the screwed groove in the base stock 20 and the screwed projection in the working part 11. By forming the gap 50, the working part 11 can be made to rotate to the base stock 20, and the working part 11 can be pulled out from the base stock 20.

摘要： PURPOSE:To reduce the amount of work and time required to adjust the phases of threaded reinforcing bars by moving the threaded reinforcing bars close to and away from each other simply through the rotation of screw members in opposite directions. CONSTITUTION:A cylindrical screw member 30 has first and second tapped holes 31, 32 formed at both ends. The tapped holes 31, 32 have their axes made to coincide with that of the screw member 30, and have their helices in opposite directions. Screw portions 42A, 42B formed at the ends of respective holding members 40A, 40B are driven into the respective tapped holes 31, 32. Mounting grooves are formed at the lower ends of the holding members 40A, 40B and parallel to the screw portions 42A, 42B. Threaded reinforcing bars 1A, 1B passed through the mounting grooves are held in place by means of clamping bolts 60, 60.
