Description

(1) Technical field

[0001] The invention relates to a cast-in-place concrete hollow slab. (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 hollow, and its sh...
