Description

Steel cage truss welding system

technical field

The invention relates to the technical field of construction machinery and equipment, in particular to a steel cage truss welding system.

Background technique

In engineering construction, in order to ensure the strength of the foundation pit wall, steel cages will be added to the underground diaphragm wall to restrain the concrete and improve the reliability of the construction structure.

In the existing steel cage processing technology, the assembly and welding of the truss accounts for a large part of the workload. As shown in Figure 1, the truss is composed of main tendons and zigzag tendons. In the production process of the truss, workers need to complete the assembly of the main reinforcement first, then place the zigzag reinforcement between the two main reinforcements, and then weld the overlap between the zigzag reinforcement and the main reinforcement by the welder. After welding one side of the truss, the worker manually lifts the whole truss and rotates it 180 degrees, and continues to weld the other side. Finally, the worker lifts and transports the truss to the installation position of the reinforcement cage manufacturing platform, erects the truss and welds it to the main body of the reinforcement cage.

Above-mentioned production process mainly has the following weak points:

1. The degree of automation is low, the demand for workers is large, and the production efficiency is low;

2. The stability of workers placing the main reinforcement and zigzag reinforcement is poor, the deviation of shape and position is large, and the quality of the manual arc welding seam is unstable, which is not conducive to the stability of the stiffness of the truss and the overall quality control of the reinforcement cage.
