Description

Easy disassembly and reusable steel cage spreader

technical field

The utility model relates to a sling used for overall hoisting of a beam yard, in particular to a rebar cage sling which is easy to assemble and disassemble and can be reused.

Background technique

At present, steel cages are widely used in the construction of new railways, bridges, and high-rise buildings. The hoisting and transportation of steel cages in beam yards or during construction is generally completed by ropes or hooks, which are easy to stretch and deform the steel cages. The middle steel cage is prone to deflection and difficult to adjust. The upper and lower steel cages cannot be accurately positioned, which will hinder the butt joint work of the connecting sleeve, affect the butt joint effect of the steel cage, reduce the construction efficiency of the pile foundation, and reduce the The quality of the pile foundation.

In the prefabrication process of box girders, the traditional spreader used to lift the steel cage is welded by section steel. This kind of steel cage spreader is generally used for blanking and welding at the construction site. Since the site does not have professional blanking tools and accurate welding molds, it is difficult to control the welding deformation. Cause the failure of making the spreader and affect the quality of the hoisting of the steel cage. In addition, although the rigidity can be ensured by increasing the size and amount of large steel, it will greatly increase the cost and cause a waste of funds. In addition, this kind of spreader is a fixed type, which is not suitable for transportation due to its bulky size. It can only be used as a one-time investment in the beam yard, and the transfer cost is too high.
