Floor slab concrete thickness and reinforced concrete protective layer controller

Abstract

The invention relates to a floor slab concrete thickness and reinforced concrete protective layer controller. The controller comprises a main pipe, a fixing ring, a protective ring, a bottom rib reinforced concrete protective layer positioning plate and a surface rib reinforced concrete protective layer positioning plate, wherein the main pipe is a circular pipeline, a through hole penetrating through an inner cavity of the main pipe is formed in the pipe wall of the main pipe, the fixing ring is perpendicularly connected to the bottom end of the main pipe, the protective ring is perpendicularly connected to the top end of the main pipe, the bottom rib reinforced concrete protective layer positioning plate is connected to the position, close to the bottom end, of the outer surface of the main pipe, and the surface rib reinforced concrete protective layer positioning plate is connected to the position, close to the top end, of the outer surface of the main pipe. By adoption of the controller, the concrete thickness of a floor slab can be accurately controlled in the pouring process, and the thickness of steel bar protective layers can be well controlled.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a controller for floor concrete thickness and reinforced concrete protective layer. Background technique [0002] In construction projects, the control of the thickness of floor concrete and the thickness of steel bar cover has always been a difficult point in the construction of main concrete. The current common practice is to measure the elevation to the construction work surface to control the location of the floor elevation, and then use the short steel bars prepared in advance to insert into the concrete during the concrete pouring process to check the pouring thickness of the cast-in-place concrete. To control the thickness of the concrete pouring of the floor slab; and the control of the thickness of the reinforced concrete protective layer is generally carried out by placing marble pads and steel bar stools during the stage of binding steel bars.

AI Technical Summary

Problems solved by technology

[0004] 1. The thickness control of cast-in-place concrete for traditional floor slabs is labor-intensive, time-consuming, high in cost and low in accuracy

In the traditional way, when the concrete is poured on the floor, a special person is required to carry the prepared short steel bars. During the concrete pouring process, the thickness of the floor pouring is continuously detected and controlled, which requires extra manpower; the control process is subjective judgment by humans, reducing The accuracy of floor slab thickness control is affected; there is a certain overlap with the on-site concrete pouring work, which affects construction efficiency; the final effect of floor slab cast-in-place concrete thickness control is often not ideal

The specification allows the thickness deviation of the floor slab to be +10mm and -5mm, but in reality, the concrete is often poured too thick due to inaccurate control of the thickness of the floor slab, which greatly increases the construction cost

[0005] 2. The thickness of the traditional reinforced concrete protective layer is controlled, the strength is low, the production is cumbersome, easy to move, and the effect is poor

In the concrete pouring process of the floor slab, even if the marble pads and steel horse stools are placed in the stage of steel bar binding, due to the trampling of the steel bars by the workers and the lateral force during the concrete pouring process, the horse stools will often cause the horse stools to overturn. or the bottom reinforcement of the slab is out of the position of the pad, resulting in insufficient or too large reinforced concrete cover of the floor, too small spacing between the gluten and the bottom reinforcement, etc.
