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 (3) encloses to form a hollow cavity (1) with a cavity (4); the tire is characterized in that the embryo of the outer wall (3) is in an integrated embryo; the embryo is enclosed and jointed, and the embryo edge is cemented, to form the hollow tire (1); a cementation belt is formed at the cemented section; the inner side of at least a jointing cementation belt is provided with a supporting mould (6); the supporting mould (6) is provided with a drop hanger (7) which extends outwards. The hollow tire is applicable to hollow floor systems, roofs, foundation slabs, walls or hollow bridges made of cast-in-situ reinforced concrete or pre-stressed reinforced concrete, in particular applicable to hollow girderless floor systems.

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 200410155253.2, and a title of "a lightweight carcass 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 fo...

AI Technical Summary

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
