Description
Technical Field
The utility model belongs to the technical field of the assembly type structure, a concatenation formula prestressing force superimposed sheet is related to.
Background
The reinforced concrete composite slab is an assembled integral floor slab formed by overlapping a prefabricated slab and a cast-in-place reinforced concrete layer. The composite floor slab has good integrity, the upper and lower surfaces of the slab are smooth, the decoration of a finish coat is convenient, and the composite floor slab is suitable for high-rise buildings and large-bay buildings with higher requirement on the integral rigidity. At present, the existing reinforced concrete composite slab is generally hoisted in place by means of hoisting machinery and then assembled, gaps between the composite slabs are often too large after assembly is completed, the laminating degree between the composite slabs is not tight enough, gaps occur between the composite slabs, and the integral connection performance of the assembled floor slab is poor, so that the problem of the prior assembled reinforced concrete composite slab is solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a concatenation formula prestressing force superimposed sheet to the problem that prior art exists.
Therefore, the utility model adopts the following technical scheme:
the utility model provides a concatenation formula prestressing force superimposed sheet, the package rubbing board body, the plate body is the rectangle structure, and the one end of plate body is equipped with the lower connecting plate with plate body parallel arrangement, the lower surface of lower connecting plate and the lower surface coplane of plate body, the one end that the lower connecting plate was kept away from to the plate body is equipped with the upper junction plate with plate body parallel arrangement, the upper surface of upper junction plate and the upper surface coplane of plate body, the upper surface of lower connecting plate is equipped with a plurality of screw rods that are vertical setting, be equipped with a plurality of through-holes with screw rod looks adaptation on the upper junction plate.
Further, the upper connecting plate and the lower connecting plate are rectangular.
Further, the upper surface of lower connecting plate is equipped with a plurality of location sand grips along its width direction, the cross section of location sand grip is trapezoidal, the lower surface of upper junction plate be equipped with a plurality of with the positioning groove of location sand grip looks adaptation.
Furthermore, a counter bore is arranged on the upper connecting plate, and the through hole is located in the counter bore.
Further, the thickness of the upper connecting plate and the lower connecting plate is half of the thickness of the plate body.
The beneficial effects of the utility model reside in that: the lower connecting plates and the upper connecting plates are arranged at the two ends of the plate bodies, and the lower connecting plates and the upper connecting plates of the two plate bodies are spliced, so that the splicing mode is simple and quick, and labor is greatly saved; after splicing is completed, connection is firm and stable; simple structure and convenient manufacture.
