Description
Technical field
The present invention relates to building material technical field, say be in detail a kind of according to simple in structure, be convenient to dismounting and transportation, the interior formwork of cast-in-situ concrete hollow slab easy to use.
Background technology
We know, in order to reduce own wt, the saving of highrise building, save material and make building more firm, and in building constructions field, concrete floorslab is solid floor substantially at present.Cassette ceiling is at the scene in casting process, hollow interior formwork is set in concrete and forms; Interior formwork, as a kind of constructional materials of concrete floorslab, generally adopts plastics or glass fiber reinkorced concrete (GRC) to make.The existing interior formwork for cast-in-place concrete hollow floor slab, by the cuboid or the gengon that mutually fasten, be the hollow that container-like upper shell and lower house form, on the periphery of upper shell and lower house inner side, be evenly equipped with corresponding Connection Block, the corresponding spliced eye that is provided with on the Connection Block of upper shell and lower house, upper shell and lower house are provided with the binding groove being fastened as a whole for tying up; During use, upper shell and lower house is involutory, use iron wire bundle to be combined into integral body.This interior formwork, compressive strength is low, casting process middle shell pressurized is yielding, and easily sink in upper side pressurized middle part.No matter existing interior formwork is used plastics or glass fiber reinkorced concrete (GRC) to make, and floor space is large, and transportation is inconvenient; The interior formwork that plastics are made need to be used iron wire bundle to close, and wastes time and energy.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of compressive strength high, not yielding, easy accessibility, quick, the interior formwork of the cast-in-situ concrete hollow slab of convenient transport.
The present invention solves the technical scheme that above-mentioned the deficiencies in the prior art adopt:
The interior formwork of a kind of cast-in-situ concrete hollow slab, comprise mutual fastening, be container-like upper shell and lower house, the sidewall that it is characterized in that upper shell and lower house surrounding is outward-dipping shape and is connected with diapire, upper shell and lower house are provided with at least one cross reinforcing to housing inner bulge and at least one waling to housing inner bulge, upper shell and lower house middle inside opposite position are provided with circular positioning convex, and the periphery at the place of being in contact with one another of upper shell and lower house is provided with the double buckle cooperatively interacting.
Upper shell described in the present invention and lower house are quadrangular container shape, the sidewall of four sides each other and between sidewall and diapire smooth excessiveness be connected.
Upper shell described in the present invention and lower house outside are respectively equipped with transverse concave groove, longitudinal fluting and circular groove with cross reinforcing, waling and circular positioning convex opposite position.Transverse concave groove, longitudinal fluting and circular groove make upper shell identical with lower house wall thickness everywhere, increasing the compressive strength of formwork, are making under its prerequisite that is difficult for torsional deformation, save material, reduce manufacturing cost.
Transverse concave groove described in the present invention and longitudinal fluting are evenly equipped with reinforcing rib.Further strengthen the compressive strength of formwork.
The periphery at the place of being in contact with one another of the upper shell described in the present invention and lower house is provided with the Connection Block of relative outwardly convex, and Connection Block is provided with the plug-in type double buckle cooperatively interacting.
The Connection Block of lower house one side described in the present invention is provided with sub-buckle or the box of plug-in type double buckle, and the Connection Block of the lower house opposite side symmetrical with it is provided with box or the sub-buckle of plug-in type double buckle, and upper shell is identical with lower house.During use, upper shell returning buckle is on lower house, and the sub-buckle of plug-in type double buckle and box are mutually corresponding, and plugging together positioning instant can.Plastic products injection mo(u)lding, only needs a mold, saves manufacturing cost.
The present invention is connected with diapire because the sidewall of upper shell and lower house surrounding is outward-dipping shape, and in carrying and transportation, together with can stacking with lower house as a plurality of upper shells of rice bowl shape, conserve space, is convenient to carrying and transportation.Because housing and lower house are provided with at least one cross reinforcing to housing inner bulge and at least one waling to housing inner bulge, housing compressive strength is high, is difficult for torsional deformation.Because upper shell and lower house middle inside opposite position are provided with circular positioning convex, in use procedure, can between two circular positioning convex, add supporting sleeve, avoid formwork middle part pressurized to subside.The plug-in type double buckle of upper shell and the lower house fastening of mutually pegging graft during use, ties up easy accessibility, quick without using iron wire etc. to twine.
