Description

Reinforcing bar protective layer thickness control device

Technical Field

The utility model discloses quality control instrument, especially a steel reinforcement protective layer thickness control device of reinforced concrete wall are used in cast-in-place reinforced concrete wall construction.

Background

The reinforced concrete cast-in-place member refers to a reinforced concrete member cast in place at a construction site. The construction method is that firstly, steel bars are hooped in a concrete wall body to be poured, and then, concrete is poured. Due to the design life of the structural member, it is usually necessary to ensure that the exterior of the reinforcing bars form a concrete protective layer of a set thickness, such as the inverted arch of a tunnel. The inverted arch is a reverse arch structure arranged at the bottom of the tunnel for improving the stress condition of an upper supporting structure, is one of main components of the tunnel structure, and is used for effectively transmitting the pressure of the stratum at the upper part of the tunnel to the ground through a side wall structure of the tunnel or the load on the road surface and also effectively resisting the counter force transmitted from the stratum at the lower part of the tunnel. When the tunnel inverted arch is in construction and is pour, need have a layer of concrete protective layer between inside reinforcing bar and the outside, the thickness of this concrete protective layer can be according to the design difference and change to some extent. Thickness control device among the prior art, including stand and reinforcing bar stop member, through screw rod adjusting distance between stand and the reinforcing bar stop member, but reinforcing bar stop member comprises three component, including the fixed fastener that has the draw-in groove and the activity fastener that is located the draw-in groove outside to and connect a plurality of n shape checkposts of fixed fastener and activity fastener. When the steel bar clamping device is used, the steel bars are limited in the clamping grooves, and the n-shaped clamping pieces form fixed connection between the fixed clamping pieces and the movable clamping pieces. The operation process of steel bar fixing and unlocking is complicated, and the efficiency is low. For this reason, further improvement is required.
