Description

Technical Field

[0001] The utility model relates to the technical field of steel bar fixing, in particular to a steel bar positioning and installing fixture. Background Art

[0002] Rebar is a type of steel used in concrete structures, usually in round or flat shapes. It has high strength and good ductility, can enhance the tensile strength of concrete, improve the bearing capacity and earthquake resistance of the structure. In construction projects, rebar is widely used to reinforce and strengthen components such as beams, columns, and slabs, making the building more solid and durable.

[0003] When steel bars are in use, adjacent steel bars need to be welded. When welding adjacent steel bars, a steel bar positioning and installation fixture is required. However, the existing steel bar positioning and installation fixture has a poor positioning effect on the steel bars. The positions of adjacent steel bars are prone to offset, which reduces the welding effect of adjacent steel bars. In addition, manual movement of steel bars is troublesome and has low work efficiency. Therefore, we propose a steel bar positioning and installation fixture. Utility Model Content
