Height-adjustable recyclable reinforcing steel bar split heads

Abstract

The invention relates to a split heads for binding reinforcing steel bars in building engineering, in particular to a height-adjustable recyclable reinforcing steel bar split heads. The height-adjustable recyclable reinforcing steel bar split heads comprises a lifting hook, a lifting mechanism and a bracket. The bracket comprises a tray with a central through hole, and three supporting legs which are distributed in a triangular shape are hinged to the lower portion of the tray. The lifting mechanism is a lead screw lifting mechanism, a screw of the lead screw lifting mechanism is sleeved by a handle sleeve integrally and fixedly connected with a nut, the screw is inserted into the central through hole of the tray to enable the lead screw lifting mechanism to be wholly assembled on the bracket, and the lifting hook for lifting reinforcing steel bars is welded at the lower end of the screw. The height-adjustable recyclable reinforcing steel bar split heads enables reinforcing steel bar meshes to be adjusted continuously and is light and convenient to adjust. Angles of the supporting legs can be adjusted to enable the split heads to be placed at will. The height of the lifting hook and the angles can be reduced and changed at will to enable the lifting hook and the supporting legs to be conveniently pulled out of concrete. After the concrete is poured, the split heads is easy to dismount. The split heads can be manufactured by using corner waste materials in construction sites, so that the materials are convenient to obtain. The split heads saves materials and is simple to manufacture.

Description

technical field [0001] The invention relates to a horse stool for binding steel bars in construction engineering, in particular to a height-adjustable and reusable steel bar horse stool. Background technique [0002] At present, before the roof concrete is poured in industrial and civil construction projects, stirrup irons are often used to jack up the bound upper layer of steel mesh to maintain the distance from the lower layer of steel mesh and ensure the quality of reinforced concrete pouring. The height of the traditional stirrup iron is fixed. When the spacing of the steel mesh needs to be adjusted, the stirrup iron of different specifications can only be replaced, and it cannot be taken out and reused after the pouring construction is completed, wasting materials.

AI Technical Summary

Problems solved by technology

The height of the traditional stirrup iron is fixed. When it is necessary to adjust the spacing of the steel mesh, you can only replace the stirrup iron with different specifications, and it cannot be taken out and reused after the pouring construction is completed, which wastes materials.

[0003] CN201220039832.0 discloses a height-adjustable and turnable steel bar horse stool, which belongs to the manual lifting of the draw hook to a certain height and at the same time hooks the draw hook on the steel mesh, and then uses the latch for positioning. The linkage action is complicated and there are many operation steps. It is suitable for steel mesh pieces with thinner steel bars and lighter weight; using the pin control to adjust the lifting height of the steel mesh pieces cannot realize continuous control of the height of the steel mesh pieces, and there is a blind area; The latch is difficult to pull out, and the stirrup is not easy to remove
