Hollow casing for in-situ concrete casting

Abstract

A hollow carcass for filling cast-in-situ concrete, comprising a hollow carcass (1) and a supporting foot (2), the supporting foot (2) is arranged on the outer wall (3) of the hollow carcass (1), and the outer wall (3) is surrounded by Combine to form a hollow carcass (1) with a cavity (4), which is characterized in that the embryo body of the outer wall (3) of the hollow carcass (1) is a conjoined integral embryo body, after the embryo body is enclosed Joining and gluing the edges of the embryo body to form a hollow carcass (1), the gluing part forms a gluing belt (5), and a supporting form (6) is arranged inside at least one gluing belt (5). In this way, the seam at the cemented belt is easy, the seam quality is good, and the lap joint is firm. The hollow carcass is simple to manufacture, high in production efficiency, good in integrity, low in cost, and can be formed at one time. It is suitable for cast-in-place reinforced concrete or Prestressed reinforced concrete hollow slabs, floors, roofs, walls, foundation slabs and bridges, 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 this kind of building components is inconvenient to make during production, the production efficiency is low, it is not convenient for assembly line production, and the corresponding cost is high
