Embodiment Construction

[0183] The present invention will be further described below in conjunction with drawings and embodiments.

[0184] As shown in the accompanying drawings, the present invention is a cast-in-place concrete hollow slab, which includes cast-in-place concrete 54 and a mandrel 55. The mandrel 55 is wrapped in the cast-in-place concrete 54. Buckled together, the pot-shaped member 1 is composed of a pot bottom plate 4 and a pot side wall 5. The pot side wall 5 is provided with a vertical groove 2, and the pot-shaped member 1 is also provided with a raised edge 3. The mandrel 55 is mutually Arranged alternately, there are cast-in-place concrete ribs 52 between each other, which is characterized in that a pad 48 is arranged between two relatively fastened basin-shaped components 1, and cast-in-place concrete ribs 53 are formed in the groove 2 . figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the attached drawings, 1 is a pot-shaped component...

Abstract

A cast-in-place concrete hollow slab comprises a cast-in-place concrete (54) and core modules (55); the core modules (55) are wrapped in the cast-in-place concrete (54), two basin-shaped elements (1) are oppositely buttoned to form the core module (55), the basin-shaped element (1) consists of a basin floor plate (4) and a basin side wall (5), the basin side wall (5) is provided with a vertical groove (2), the basin-shaped element (1) is also provided with a raising edge (3), the core modules (55) are mutually and alternately arranged, and cast-in-place concrete ribs (52) are arranged between the core modules. The hollow slab is characterized in that a furring piece (48) is arranged between two oppositely buttoned basin-shaped elements (1), and the cast-in-place concrete forms forms a cast-in-place concrete bar (53) at the groove (2) part. Therefore, according to the different requirements of design and construction, the furring piece is arranged between the oppositely buttoned basin-shaped elements, the basin-shaped element is no need to be additionally produced, thus being beneficial to application and promotion of the basin-shaped elements; and simultaneously, the basin side wall is provided with the vertical groove which can play a role of reinforcing to the structure, the deformation is not easy to happen during use, therefore the purpose of the invention is achieved. The concrete hollow slab is applicable to the cast-in-place reinforcing steel bar concrete or prestressed reinforcing steel bar concrete hollow floor cover, roof, wall, foundation slab and bridge, in particular to the use of the hollow floor cover.

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, 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" pa...
