Description

Integrated split heads of cast-in-situ concrete slab of accurate control Technical Field The utility model relates to an integrated split heads, in particular to an integrated split heads for accurately controlling cast-in-situ concrete slabs. Background In recent years, through intensive research and long-term practical analysis, dimensional deviation of a floor structure in the construction process, especially errors of the thickness and flatness of the floor, and thickness problems of a reinforcement protection layer are found to become key factors influencing the structural quality of the floor. These problems are not only related to the initial quality of the construction project, but also directly affect the durability and aesthetics of the building. The traditional construction method has a plurality of defects in the aspect of controlling the structural dimensional accuracy of the floor, such as complex specification of the split heads required to be matched for the floor with different sizes and complex on-site allocation, and the split heads of the strip split heads and the point type supports have defects in stability, so that the rigidity of the reinforcing steel bars is insufficient, the reinforcing steel bars are easy to damage in the construction process, and the protection effect of finished products is further affected. In addition, the defect that the floor protection layer is unqualified after concrete pouring and tamping easily causes cracking and the like brings great trouble to later repair. Disclosure of utility model The integrated split heads for accurately controlling the cast-in-situ concrete slab can effectively regulate and have stability, can realize integrated control of the thickness of the upper and lower reinforcement protection layers, the thickness of the floor, the flatness of the floor, the elevation of the slab and other functions, greatly simplify the control flow, finely control the flatness of the floor, reduce the construction cost and improve the economic benefit. In order to solve the technical problems, the utility model adopts the following technical scheme: The integrated split heads for accurately controlling the cast-in-situ concrete slab comprise an upper supporting disc and a lower supporting disc, wherein the upper supporting disc and the lower supporting disc are identical in structure and comprise threaded sleeves, the threaded sleeves are fixedly connected with a circular ring through a circumferential connecting rod, and the threaded sleeves of the upper supporting disc and the lower supporting disc are in threaded connection with a screw rod. The lower end of the circular ring of the lower supporting disc is fixedly provided with a supporting leg. The top end of the screw rod is connected with an elevation control nut in a threaded manner. The upper supporting plate and the lower supporting plate are made of steel bars. The support legs are at least 3 groups. The bottom end is equipped with the bottom sprag under the screw rod. The bottom support is a plurality of support rods, the plurality of support rods are circumferentially arranged, one ends of the plurality of support rods are fixedly connected with the screw rods, and the other ends of the plurality of support rods horizontally extend outwards. The utility model provides an integrated split heads for accurately controlling cast-in-situ concrete slabs, which has the following technical effects: 1) The upper support plate, the lower support plate and the screw rod are in threaded connection, and the support legs and the lower support plate are in threaded connection, so that flexible adjustment in height can be performed, the requirements of various floor slabs on thickness can be met, and the thickness of the protective layer of the main ribs with different specifications can be accurately controlled. The design is skillfully suitable for matching different plate thicknesses and various steel bar specifications in the existing project, so that the floor slab with the thickness of 100-250 mm can be suitable for use. The split heads effectively replace the traditional cushion blocks, the epithelial ribs support split heads, elevation control points and other accessories, realize integrated control of multiple functions such as thickness of the upper and lower reinforcement protection layers, thickness of the floor, flatness of the floor, elevation of the plate surface and the like, and greatly simplify control flow. 2) The leveling control point of the leveling layer is arranged at the upper end of the elevation control nut through the elevation control nut with adjustable height, so that the flatness of the floor slab can be controlled more finely. In addition, the two circular discs of the split heads are designed to effectively increase the stressed area and improve the integral bending resistance of the floor slab reinforcing steel bars. The method can better protect the floor slab reinforce
