Problems solved by technology

However, it is inconvenient to make this type of formwork member, the production efficiency is low, it is not convenient for assembly line production, the cost is high, 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 urgent need

Embodiment Construction

[0061] The present invention will be further described below in conjunction with the drawings and embodiments.

[0062] As shown in the drawings, the present invention includes a reinforced concrete 1 and a formwork member 2. The formwork member 2 is wrapped in the reinforced concrete 1, and the 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, a surrounding side wall 5, and a lower bottom 6 enclose a polyhedral cavity mold shell member 2, an upper plate 4, a surrounding side wall 5, and a lower bottom 6. At least one of the containing reinforcement 7 is characterized in that at least two adjacent or identical members between the upper plate 4, the surrounding side walls 5 or the lower bottom 6 are connected by a relative rotation structure or device 8 Thus, the relative rotation structure or device 8 ...

Abstract

The invention is a cast-in-site concrete hollow slab, comprising reinforced concrete and form components, where the form components are wrapped by the reinforced concrete and staggeredly arranged, cast- in-site reinforced concrete ribs are arranged between them, and each form component comprises top plate, peripheral side wall, and infrabasal plate, which compose a polyhedral cavity form component, at least one of the top plate, peripheral side wall and infrabasal plate contains reinforcer, and it is characterized in that: at least two adjacent or same components between the top plate, peripheral side wall and infrabasal plate are interconnected by relatively rotating structure or device, which is fixed on the top plate, peripheral side wall, or infrabasal plate. And the invention is applied to cast-in-site reinforced concrete or prestressed reinforced concrete hollow floor systems, house covers, walls, foundation slabs and hollow bridges.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, cast-in-place 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 the application number 01140106.0 and the publication number CN1356442 that the applicant filed on November 23, 2001 for the invention pate...
