Description

Technical Field

[0002] The steel structure column foot reinforcement positioning fixture is a tool specially used for positioning reinforcement, which plays an important role in the concrete pouring process of the steel structure column foot. Its main function is to ensure that the position of the reinforcement is stable and unchanged, thereby ensuring the stability and safety of the entire building structure. The reinforcement skeleton is positioned by the positioning fixture to ensure that the distance between the reinforcement and the embedded ring plate and the spacing between the main reinforcement of the column do not deviate during the pouring of concrete. This not only reduces or even eliminates the quality problems caused by the deviation of the reinforcement from the design position, avoids rework, but also plays a role in reducing costs and increasing efficiency. Therefore, in the construction process of steel structure buildings, the application of this positioning fixture will become more and more extensive.

[0027] The detailed working process of the utility model is as follows:

[0028] During use, when it is necessary to position the steel bars of the steel structure column foot, the base is put on the steel structure column foot, and the frame mechanism is adjusted according to the steel structure column foot. The No. 1 worm 2 is rotated by the knob, and the No. 1 worm 2 drives the No. 1 bevel gear 6 to rotate, and then drives the No. 2 bevel gear 7 and the No. 2 worm 3 to rotate through meshing transmission.

With the cooperation of the limiting slide groove 21 and multiple limiting sliders 22, multiple clamping nuts 19 are grouped in pairs and move toward each other. When the steel bars need to be clamped, the clamping nuts 19 of each group are close to each other to achieve the clamping positioning of the steel bars between the two. In this way, it can be used for steel bars of different thicknesses, has stronger applicability, and also improves the reuse rate to avoid waste of resources.
