Description

Technical Field

[0001] The utility model relates to the technical field of steel bar quick connection clamps, in particular to a steel bar quick connection clamp. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. During the cold drawing and cold rolling process, the coiled steel wire may break due to factors such as the welding quality of the welded joint and tension control during the production process. At this time, the steel bars at the broken part need to be pulled to the detached part and welded together. In order to facilitate the connection and fixation of the steel bars and make it easier for the staff to pull out the steel bars, a steel bar quick connection chuck is needed.

[0003] At present, the connection of steel bars on construction sites is usually done by straight thread sleeves or welding with electric welders. These methods are still a bit cumbersome, especially for temporary small-batch processing of connecting steel bars. For this reason, we propose a steel bar quick connection chuck to solve the existing problem. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The steel bar quick connection chuck can fix the steel bar by combining the clamping plate, rotating structure and push plate. During the fixing process, the fixing block can be used to fix the steel bar in the direction of the pattern on both sides to prevent the steel bar from falling off due to stress.

[0012] 2. The steel bar quick connection chuck can be used in conjunction with a push plate and bolts to provide a second fix for the steel bar, adding an extra layer of safety hazard. BRIEF DESCRIPTION OF THE DRAWINGS
