Hollow casing for in-situ concrete casting

Abstract

A hollow carcass for filling cast-in-place concrete, comprising a hollow carcass (1) and a support foot (2), the support foot (2) being arranged on the bottom outer wall (3) of the hollow carcass (1), the outer wall (3) A hollow carcass (1) with a cavity (4) enclosed and formed is characterized in that the hollow carcass (1) is a hexahedron, and the hollow carcass (1) is an open basin-shaped integral embryo formed by a five-sided embryo body. The body (5) is formed with one side of prefabricated outer wall (6), and the prefabricated outer wall (6) closes the opening surface of the basin-shaped embryo body (5), and is glued together to form an integral hollow carcass. In this way, the hollow carcass is easy to manufacture, high in production efficiency, good in integrity, and low in cost; in addition, the hollow carcass also has the characteristics of simple structure, high strength, high rigidity, excellent deformation resistance, vibration resistance, and fast construction speed. It is suitable for hollow slabs, floors, roofs, walls, foundation slabs and bridges of cast-in-place reinforced concrete or prestressed reinforced concrete, especially for hollow beamless floors.

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
