Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a steel bar coupling in the construction field. Background Art

[0002] The steel cage mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low.

Then the steel cage is lowered into the pile hole, and then the conduit is inserted for concrete pouring.

[0003] The lower ends of various types of cement piers are generally fixed by steel bar groups, which are composed of multiple steel bars distributed in an approximately square shape. Steel bar rings are used to fix the outside of the steel bars. However, after the poured cement solidifies, the inside expands and the fastened steel bar rings often twist and deform, resulting in poor overall stability and a major safety hazard.
