Hollow tire body for cast-in-situ concrete filling

Abstract

Disclosed is a hollow body used for filling the cast-in-place steel reinforced concrete. The invention comprises a hollow body (1), wherein, the hollow body (1) is surrounded by outer walls (2), and a cavity (3) is arranged in the hollow body (1). The hollow body is characterized in that the outer walls (2) of the upper part or lower part of the hollow body (1) are overlapped, cemented and hardened by pre-cast slab walls (4) and slurry embryos (5), the pre-cast slab wall (4) and the slurry embryos (5) are overlapped, cemented and hardened with the inside to be hard and the outside to be soft, a reinforcement (6) is arranged in the overlapped layer of the slurry embryos (5), and the reinforcement (6) is exposed outside the hollow body (1). The hollow body is suitable for the use in hollow slabs, floors, house roofs, wall bodies, foundation slabs and bridges of cast-in-place steel reinforced concrete or pre-stress steel reinforced concrete, in particular to the use in hollow non-beam floors.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 11, 2004, an application number of 200410155218.0, 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...
