Problems solved by technology

However, this formwork member is inconvenient to manufacture, low in production efficiency, inconvenient for assembly line production, and high in cost, and the construction cost of the corresponding cast-in-place concrete hollow slab is high. Therefore, developing a new type of cast-in-place concrete hollow slab has become a urgent need

Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] As shown in the accompanying drawings, the present invention includes reinforced concrete 1, formwork components 2, the formwork components 2 are wrapped in the reinforced concrete 1, the formwork components 2 are arranged alternately, and there are cast-in-situ reinforced concrete ribs 3 between each other, and the formwork The component 2 includes an upper plate 4, a surrounding side wall 5, and a lower bottom plate 6. The upper plate 4 and the surrounding side walls 5 form a cavity formwork 7. On the lower base plate 6, at least two cavity formworks 7 are arranged alternately. At least one cast-in-place structural inner rib cavity 8 is formed between the formwork shells 7, and the cast-in-place reinforced concrete 1 forms a cast-in-situ reinforced concrete inner rib 9 in the inner rib cavity 8, and is connected with the cast-in-place reinforced...

Abstract

The in-situ cast hollow concrete slab includes reinforced concrete and shuttering members ranged at intervals and wrapped with the in-situ cast reinforced concrete. The shuttering member includes upper slab, side walls and bottom. The upper slab, the side walls and the bottom enclose to form the hollow shuttering member, and on the bottom, there are at least two hollow shutterings. Between two hollow shutterings, at least one inner rib cavity is formed for forming in-situ cast reinforced concrete inner rib. The present invention features that at least one of inner rib cavity has superposed bottom with at least one prefabricated layer. The present invention is suitable for use in various kinds of in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, etc.

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 slab is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. 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 application number applied by the applicant on November 23, 2001 is 01140106.0, the publication number is CN1356442, and the name is called "a kind of cavity structure formwork for cast-in-place reinforced concrete floor slab" pat...
