Description

Controller for thickness of reinforced concrete floor slab and thickness of reinforced protection layer Technical Field The invention belongs to the technical field of building construction, and particularly relates to a controller for the thickness of a reinforced concrete floor slab and the thickness of a reinforced protection layer. Background The cast-in-situ reinforced concrete floor slab is one produced through formwork support, binding reinforcing steel bars, casting concrete, curing and demolding. In engineering construction sites, most of stressed structures such as structural foundations, plates and walls are internally provided with reinforcing steel bars, and the quality of the structural molding quality is also closely related to the factors such as the spacing of the reinforcing steel bars, the thickness of protective layers of the reinforcing steel bars, the thickness of a concrete structure and the like. In the prior art, the floor bottom rib construction mode is to place concrete or plastic cushion blocks to ensure the thickness of a reinforcement protection layer, binding wires are adopted to ensure the distance between the reinforcements, and the mode of manual cutting of marked reinforcements is used for determining whether the thickness of a concrete structure meets the requirement. The method has the defects that the cushion block, the split heads and the binding wires are adopted to bind the steel bars, the problems that the cushion block is broken or shifted, the binding wires and the steel bars fall off or break off and the like due to concrete pouring and personnel treading easily occur, the thickness and the spacing of the protection layers of the floor steel bars cannot be effectively ensured, the design requirements cannot be met, the bearing strength of the floor cannot be ensured, the construction quality of a building structure is seriously influenced, and certain potential safety hazards exist. And place work time consuming such as cushion, split heads muscle and wire ligature and be loaded down with trivial details construction, influence the construction progress. The application publication number CN115288367 discloses a location structure of concrete floor reinforcing bar and construction method thereof, its vertical location component includes screw thread post, upper fixing portion and lower fixing portion, screw thread post top screw thread installation upper fixing portion, bottom screw thread installation lower fixing portion, upper fixing portion is used for fixed third layer reinforcing bar and fourth layer reinforcing bar, lower fixing portion is used for fixed first layer reinforcing bar and second floor reinforcing bar to install adjusting sleeve between screw thread post and upper fixing portion, adjust vertical location component's height through increasing and decreasing adjusting sleeve's quantity. However, in the scheme, the mode of fixing the first layer of steel bars, the second layer of steel bars, the third layer of steel bars and the fourth layer of steel bars by the vertical positioning member is to lock the cross formed by the connection of the steel bars, and the defect is that in an actual construction scene, the cross angle formed by the arrangement of the steel bars is not necessarily 90 degrees, certain errors exist, the generated errors easily cause the fact that the upper fixing part and the lower fixing part cannot be clamped and lock the cross of the steel bars, the practicability is poor, and the device is only positioned at the cross formed by the connection of the steel bars, so that the supporting effect of the whole steel bar net is poor, and the steel bar net is easy to deform and shift when concrete pouring and personnel trample, so that the construction effect is affected.
