AI Technical Summary

Technical Problem

Existing concrete slab thickness controllers cannot be precisely adjusted during construction, resulting in low construction efficiency and significant material waste.

Method used

A concrete slab thickness controller was designed, comprising an adjustment structure, a support structure, and a fixing structure. The height is precisely adjusted by using a threaded connection between a threaded rod and a threaded rod sleeve, along with an adjustment handle on an extension plate. The support structure is a right-angled triangle connection consisting of a top support plate, a support rod, and first and second base plates, which enhances structural stability. The fixing structure uses grooves in the top and bottom reinforcing bars to clamp the reinforcing bars, and utilizes rubber anti-slip pads to improve the fixing effect.

Benefits of technology

It enables precise control and convenient adjustment of floor slab thickness, improves construction efficiency, reduces material waste, and ensures construction quality.

Abstract

The application discloses a concrete floor thickness controller capable of automatically adjusting height, which comprises an adjusting structure, a supporting structure and a fixing structure, wherein the adjusting structure is connected with the supporting structure, and the fixing structure is connected with the adjusting structure and the supporting structure. The application has the beneficial effects that the threaded connection of the threaded rod and the threaded rod sleeve cooperates with the adjusting handle of the extension plate side wall, so that the height of the controller can be adjusted labor-savingly and accurately, and the controller is suitable for different thickness floors; the supporting system formed by the top supporting plate, the supporting rod, the first base plate and the second base plate is matched with the upper and lower armpit plates in the shape of right-angled triangle, so that the structural strength and the bearing stability of the controller are enhanced; the first and second anti-skid lines avoid the sliding displacement of the controller in the construction process; the top and bottom rib grooves can firmly clamp the floor steel bars, and the rubber anti-skid pads on the inner walls of the grooves improve the fixing effect; the floor thickness control can be freely adjusted, and the situation that the floor thickness is complicated or the floor is lowered in the construction process is solved.
