Problems solved by technology

However, there is no reinforcing structure in this cavity formwork member, so the overall strength and rigidity of the cavity formwork member are poor, and the phenomenon of damage to the cavity formwork member is prone to occur. In the cast-in-place concrete hollow slab, it cannot be compared Participate well in the force bearing and transmission of cast-in-place concrete hollow slabs

Embodiment Construction

[0059] The present invention will be further described below in conjunction with the drawings and embodiments.

[0060] The present invention, as shown in the drawings, includes reinforced concrete 1, a formwork member 2, which is wrapped in reinforced concrete 1, and formwork members 2 are arranged alternately, with cast-in-situ reinforced concrete ribs 3 between them, and the formwork The component 2 includes an upper plate 4, a surrounding side wall 5, and a lower bottom 6. The upper plate 4, the surrounding side walls 5, and the lower bottom 6 form a polyhedral mold shell member 2. The upper plate 4, the surrounding side walls 5, and the lower bottom 6 contain Reinforcement 7, characterized in that the said formwork member 2 is provided with a reinforcement 8 which is a prefabricated reinforcement 9 or a stiffening rib plate 10, and the prefabricated reinforcement 9 or the stiffening rib plate 10 is superimposed and fixed in The wet slurry of the mold shell member 2 is hardene...

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, which enclose to form the shuttering member and contain reinforcement. The present invention features that the shuttering member is provided with prefabricated reinforcing rib or prefabricated reinforcing ribbed plate embedded on the wet mortar of the shuttering member for forming an integral through hardening. The present invention is suitable for in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, cast-in-situ concrete hollow slab is a widely used form of floor structure. The lightweight permanent tire mold filled in it has various hollow tubes and boxes, and the boxes are hollow or solid. For example, the applicant applied for a patent number ZL99249798.1 on November 29, 1999, 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, the upper plate, the surrounding side walls, and the lower bottom enclose a polyhedral cavity, and the upper plate, the surrounding side walls and the lower bottom contain fiber reinforcements. Another example is that the applicant filed on November 23, 2001, the application number is 01140106.0, the publication number is CN1356442, and the invention ...
