Description

Technical Field

[0001] The utility model relates to the technical field of processing and manufacturing steel cages, in particular to a simple tool for controlling the spacing between longitudinal bars of the steel cages. Background Art

[0002] During the construction of bridges, culverts or high-rise buildings, the foundation may be required to be piled according to the requirements. The method is to use machine punching and water grinding to drill holes, and the hole depth meets the design requirements, and then put the steel cage into the pile hole, and then insert the guide tube to pour concrete. The main role of the steel cage is the same as the force of the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high, but the tensile strength is very low. The steel cage plays a restraining role on the pile concrete, so that it can withstand a certain axial tension.

[0003] The steel cage is mainly welded by several circular steel bars and several longitudinal bars. The longitudinal bars are usually welded or tied to the circular steel bars at uniform and equal intervals. The position of the longitudinal bars is usually simply located manually, which may be inaccurate. Utility Model Content
