Hollow carcass for filling cast-in-situ concrete

Abstract

Disclosed is a hollow carcass for filling cast-in-situ concrete, which comprises a hollow carcass, a bracing strut, wherein the bracing strut (2) is arranged on the outer wall of the floor surface (3) of the hollow carcass (1), the outer wall (3) encloses the hollow carcass (1) formed with a cavity (4), characterized in that at least one outer wall panel of the hollow carcass (1) is formed by bundling the prefabricated outer wall panel (6) by the slip idiosome (5) of the outer wall (3), Thus achieving the advantages of easy manufacture, high production efficiency, and low cost. Furthermore, The hollow carcass also has the advantages of simple structure, high intensity, large rigidity, good deformation resistance, fine vibration resisting performance, convenient construction work, and rapid construction speed. the invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow boards, storied building covers, house roofing, walls, foundation bedplates and bridges, especially for hollow flat slabs.

Description

(1) Technical field [0001] The invention relates to a hollow matrix for filling cast-in-place concrete. (2) Background technology [0002] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side walls and the lower bottom form a polyhedral cavity. Another example is that the patent No. is ZL00203695.9, and the name is called "combined concrete hidden rib floor slab" utility model patent, which discloses a formwork member in its specification, which can be solid or holl...

Problems solved by technology

But when this kind of hollow carcass is applied to the floor construction, the hollow carcass cannot be accurately arranged in the middle layer of the floor, which affects the construction quality of the floor

For this reason, the patent No. is ZL01215092.4, and the name is "building component" utility model patent. The disclosed building component is a polyhedron, which can be hollow or solid. In order to ensure that this building component is applied to the floor It is arranged in the middle layer of the floor, and the outer wall of the polyhedron is provided with protruding legs, so that when the floor is poured, the legs can ensure that the hollow multi-faceted main cavity is just at the middle layer of the floor. , so as to better solve the above problems, but the production of this kind of building components is inconvenient, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high
