Hollow tire body for cast-in-situ concrete filling

Abstract

The invention relates to a hollow tire used for cast-in-situ concrete filling, which comprises a hollow tire (1); an outer wall encloses to form the hollow tire (1) with a cavity (4); the tire is characterized in that the hollow tire (1) is a hexahedron; the hollow tire (1) consists of an open basin-shaped entire embryo consisting of five embryos and a prefabricated outer wall (6); the open facesof the closed basin-shaped embryos (5) of the prefabricated outer wall (6) are cemented together to form the entire hollow tire; armbraces (2) or the outer wall(3) are / is provided with reinforcements(10); the cavity (4) is provided with a reinforcer (17); the reinforcer (17) is a prefabricated hollow bar; both ports of the hollow bar are communicated with the outside of the outer wall (3) to form a communicated hole (16). The hollow tire is applicable to hollow slabs, floor systems, roofs, walls, foundation slabs and bridges made of cast-in-situ reinforced concrete or pre-stressed reinforcedconcrete.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 26, 2004, an application number of 200410155251.3, and a title of "a hollow matrix for filling cast-in-place concrete". (1) Technical field [0002] The invention relates to a hollow matrix for filling cast-in-place concrete. (2) Background technology [0003] 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 p...

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
