AI Technical Summary

Technical Problem

In existing technologies for cast-in-place floor slab construction, the control precision of floor slab thickness and concrete cover thickness is low, and they are easily affected by the displacement of the reinforcing steel cage and errors in manual measurement, resulting in uneven thickness and affecting structural safety and durability.

Method used

A control device consisting of upper and lower pads and control ribs is used. The thickness of the concrete protective layer is controlled by the thickness of the upper and lower pads, and the control ribs define the overall height of the floor slab. Combined with the surface reinforcement support, the installation stability and accuracy are improved.

Benefits of technology

It improves the control precision of floor slab thickness and concrete protective layer thickness, enhances the load-bearing capacity and waterproof performance of the floor slab, reduces material waste, and improves construction quality and durability.
