Problems solved by technology
However, after the dense-ribbed floor is applied to this kind of lightweight member for concrete filling, the force of the floor is more complicated at the transverse corner, the stress is concentrated, and cracks are easy to occur, or even cracked and damaged. Therefore, a new type of ribbed floor is developed. Cast-in-place concrete hollow slabs are in urgent need

Embodiment Construction
[0058] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0059] As shown in the accompanying drawings, the present invention includes reinforced concrete 1 and lightweight components 2. The lightweight components 2 are contained in the reinforced concrete 1. Between the lightweight components 2 are cast-in-situ reinforced concrete ribs 3. The lightweight components 2 include The upper plate 4, the surrounding side walls 5, and the lower plate 6, the upper plate 4, the surrounding side walls 5, and the lower plate 6 form a hexahedron, which is characterized in that the corners around the upper plate 4 are upper arc angles 7, corresponding to The concrete forms a cast-in-place concrete reinforcing rib 8 at the upper arc angle 7 . In each drawing, 1 is reinforced concrete, 2 is cavity formwork member, 3 is cast-in-place reinforced concrete rib, 4 is upper plate, 5 is surrounding side wall, 6 is lower plate, 7 is...

Disclosed is a cast-in-situs concrete hollow slab, which comprises a reinforced-bar concrete (1) and lightweight members (2), the lightweight members (2) are enclosed in the reinforced-bar concrete (1), a cast-in-situ reinforced-bar rib (3) is arranged between the lightweight members (2), the lightweight members (2) comprise an upper board (1), peripheral side panels (5) and a lower board (6), the upper board (1), the peripheral side panels (5) and the lower board (6) enclose a hexahedron, characterized in that an upper chamfering (7) is arranged on the peripherial corners of the upper board (1), the corresponding cast-in-situ concrete forms cast-in-situ concrete reinforcement ribs (8) at the upper arc corner (7) position. The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.
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 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 concr...
