Concrete structure protective layer thickness control device and control method thereof

Abstract

The invention provides a concrete structure protective layer thickness control device and a control method thereof. A supporting assembly with simultaneous expansion and contraction at both ends is formed by separately screwing a screw at both ends of a connecting nut; the length of the supporting assembly is adjusted by rotating the connecting nut so as to clamp the supporting assembly between templates; and then a plurality of adjusting holes are formed in the tail end of a screw rod to install a stirrup limiter; the stirrup limiter is installed at the appropriate adjusting hole part according to the thickness of a protective layer; a limit structure that limits the position of a steel cage is formed; the thickness of the protective layer of the concrete structure does not change due tosubsequent construction. Therefore, the device provided by the invention solves the problem that the traditional construction method has difficulty in guaranteeing the thickness of the protective layer and the spacing of the stirrup. The concrete structure protective layer thickness control device with a simplified structure and convenient operation is produced. The thickness of the protective layer of the concrete structure is effectively ensured, and the stirrup is effectively fixed. The stirrups do not move laterally due to subsequent construction. The quality of the project is greatly improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a device for controlling the thickness of a concrete structure protective layer and a control method thereof. Background technique [0002] According to the new "Code for Design of Concrete Structures" (GB50010-2010) in 2010, the thickness of the protective layer is no longer the minimum distance from the outer edge of the longitudinal reinforcement (non-stirrup) to the concrete surface, but "the outermost reinforcement (including the stirrup) , structural reinforcement, distribution reinforcement, etc.) to calculate the thickness of the protective layer of concrete". The regulation of the minimum thickness of the protective layer is to meet the durability requirements of the concrete structural members and the requirements for the effective anchoring of the stressed steel bars. [0003] The larger the thickness of the concrete protective layer, the better the bond...

AI Technical Summary

Problems solved by technology

Thereby, the present invention solves the quality problems such as the thickness of the protective layer of the reinforced concrete structure and the spacing of the stirrups that are difficult to guarantee by the traditional construction method through the device, and achieves a control device for the thickness of the protective layer of the concrete structure with a simplified structure and easy operation to realize effective To ensure the thickness of the protective layer of the concrete structure, and to effectively fix the stirrups, to ensure that the stirrups do not move laterally due to subsequent construction, and to greatly improve the quality of the project, etc.
