[0002] As an important component of the pile foundation, the quality and stability of the steel cage directly affect the safety and durability of the entire pile foundation and even the entire building. Therefore, the welding technology of the steel cage is one of the key links to ensure the quality of the steel cage. In some cases, during the welding process of the steel cage, in order to reduce the deformation of the steel cage, the annular stirrups will be welded to the inner side of the main reinforcement, that is, several groups of annular stirrups are welded inside several main reinforcements arranged in a circular pattern. In the existing technology, welding is mostly done manually, which is relatively inefficient. At the same time, the main reinforcement and annular stirrups are relatively rough, and the quality is difficult to guarantee. Although it can be produced by a CNC steel cage rolling welding machine, the equipment is relatively bulky and the steel cage needs to be transported to the construction site after being produced in the factory. It is not only time-consuming but also has the problem of transportation cost. For this reason, the present invention provides a welding equipment for construction with a specific steel bar diameter.

Several groups of bearing plates 35 are evenly arranged along the circumference of the outer periphery of the disc 2 33. The main reinforcement 1 is fixed on the two corresponding shooter bearing plates 35 of the main reinforcement bearing frames 4 on both sides.

[0028] The disc mechanism also includes a circular shaft 14, and a circular shaft 14 is coaxially provided with a circular disc 15 and a gear 17. The gear 17 is arranged to rotate along the circular shaft 14. A plurality of groups of cross-shaped slide grooves are evenly arranged on the outer arc surface of the circular disc 15 in the circumferential direction. Specifically, the number of groups of cross-shaped slide grooves corresponds to the number of main ribs 1. The plurality of groups of cross-shaped slide grooves are all through the side of the circular disc 15 close to the gear 17. The plurality of groups of cross-shaped slide grooves are all slidably provided with a matching cross-shaped slide rod 16.

When the motor 26 drives the driving gear 25 to rotate, thereby driving the gear 17 to rotate, the round rod 18 slides along the arc groove 19, thereby causing the plurality of cross-shaped slide rods 16 to slide along the corresponding cross-shaped slide groove. A bearing rod 20 is provided at the outer end of the cross-shaped sliding rod 16 away from the center of the disk 15.

[0029] The load-bearing rod 20 is provided with several groups of isolation pieces, and an annular stirrup 2 is placed between two adjacent isolation pieces.

When the annular stirrup 2 is not welded, it will move with the annular stirrup 2 under the action of the stopper 21. This can be achieved by selecting a suitable spring 40. After a number of annular stirrups 2 are sleeved on the periphery of a number of groups of bearing rods 20, a motor 26 is used to make a number of cross-shaped sliding rods 16 slide outward simultaneously along the corresponding cross-shaped sliding grooves, thereby supporting and fixing the annular stirrups 2 outward through the bearing rods 20, making it convenient to subsequently weld the annular stirrups 2 to the main reinforcement 1.
