[0002] Precast concrete panels are the floor panels used in early buildings, that is, the modules or panels used in the project. They are called precast panels because they are produced and processed in the prefabrication yard and directly transported to the construction site for installation. In the production process of precast panels, steel bars are needed. Sometimes, due to the limited length of steel bars, they need to be lengthened. The traditional way is through welding or tying. Tying is prone to detachment, so most of them are welded. When welding, tools are needed to fix the steel bars to facilitate the welding operation.

The steel bar welding device for prefabricated components rotates by turning the adjusting bolt to move the clamping block downward, so that the fixing block and the clamping block clamp the steel bar, which is convenient for people to perform welding on it, solves the problem that the traditional welding method is prone to displacement, improves the stability of steel bar welding, and avoids the displacement affecting the welding quality.

[0004] When fixing the steel bars in the above-mentioned comparative patent, the operator needs to manually rotate the adjustment bolts to fix the steel bars, and the fixing operation cannot be completed quickly, and both hands cannot be free to adjust the position of the steel bars during the fixing process.
