Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a steel bar welding clamping device for building civil engineering. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross-section is circular, and sometimes square with rounded corners. During civil construction, a rebar clamping device is used to fix the rebar, which makes it easier for workers to weld the rebar. When welding, it is often necessary to align the ends of the two sections of rebar and fix them with a clamping device. However, the existing rebar clamping device is not equipped with an abutment alignment device, and generally requires manual abutment. During welding, the rebar is prone to offset, which can easily cause a large gap between the ends of the two sections of rebar, affecting the effect of rebar welding and the quality of the rebar. Utility Model Content

One end of the clamping rod 10 is screwed into the annular embedding groove through a shaft rod; a plurality of anti-slip rods 13 are integrally formed at equal angles on the outer end of the clamping rod 10. When the clamping rod 10 clamps the steel bar, the friction between the clamping rod 10 and the steel bar can be increased by the anti-slip rod 13;

[0038] The driving mechanisms 11 are four in number and are embedded in the clamping ring 8 one by one. The driving mechanisms 11 are connected to the corresponding clamping rods 10 .

[0039] Embodiment 2:

[0040] See also Figure 1 , Figure 3-4 As shown, based on Example 1, the driving mechanism 11 includes:

[0041] A driving ring 11-1, wherein the driving ring 11-1 is embedded in the annular embedding groove, and an annular slide rail 11-2 is sleeved and welded on the outer ring wall of the driving ring 11-1, and the annular slide rail 11-2 is slidably disposed in the annular embedding groove;

[0044] When using the utility model, the two sections of steel bars to be welded are respectively inserted into the two clamping rings 8 on the fixing frames 2 on both sides, and the adjacent ends of the two steel bars are exposed on the side of the fixing frame 2 adjacent to the center of the bottom plate 1.
