Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings.
A construction steel bar welding connector, as shown in figure 1, comprises a round sleeve 1, wherein the round sleeve 1 is of a metal structure, the inner diameter of the round sleeve 1 needs to be slightly larger than the outer diameter of the end part of a steel bar for welding connection, thus, the round sleeve 1 can be sleeved at the end part of the steel bar, the left part and the right part of the round sleeve 1 are communicated, a plurality of notches 2 are uniformly arranged at the left and right parts of the circular sleeve 1, the notches 2 are in a strip shape, which is kept in parallel relation with the central axis of the circular sleeve 1, edge strips 3 are formed on the circular sleeve 1 between the notches 2, the edge strips 3 are also in a strip-shaped structure, a plurality of convex strips 4 in a convex state are uniformly arranged on the outer wall of the circular sleeve 1, the convex strips 4 are also in a strip-shaped structure, which is parallel to the central axis of the circular sleeve 1, and the convex strips 4 extend to the outer side surface of the edge strip 3.
