Technical Field

The utility model belongs to the technical field of preventing steel bars from being exposed when concrete is poured, and particularly relates to a steel bar cushion block.

Background

The steel bar cushion block is also called a steel bar protection layer cushion block, is an auxiliary concrete structure which is arranged between the steel bars and the templates in the brick-concrete structure and in the frame structure, and is used for preventing the steel bars from being exposed and corroded. When concrete is poured, the steel bars can be exposed by tightly attaching the template due to the fact that the cushion blocks of the steel bar protection layer move, the cushion blocks are too few or the cushion blocks fall off and are missed. And the exposed steel bars are easy to corrode, so that the stress of the steel bars is reduced.
