AI Technical Summary
When the existing construction units control the slab thickness and the thickness of the steel bar protective layer of the cast-in-place concrete slab, the two interrelated indicators are controlled separately, resulting in a deviation in the control of the slab thickness and elevation, which affects the pass rate of the protective layer. In addition, the position of the cast-in-place concrete slab and roof panel is greatly affected by fewer elevation measurement points, resulting in the comprehensive pass rate of the slab thickness and protective layer thickness that cannot meet the acceptance requirements.
A comprehensive control device for plate thickness of steel bar protective layer is designed, including concrete base of steel bar protective layer, A triangle iron plate, supporting steel bar, B triangle iron plate, steel bar protective layer control top cap and plate thickness control pad. Through the fixed connection of these components and wire mesh configuration, unified control of plate thickness and protective layer thickness is achieved.
This device can effectively ensure the control consistency between the slab thickness and the steel bar protective layer, improve the accuracy and efficiency of construction, and is especially suitable for large-area industrial factory floors, floor slabs and roof panels required for waterproofing, reducing the risk of water leakage.
