Problems solved by technology
However, this kind of thin-walled box formwork member, as an integral thin-walled box member, takes up a lot of space during transportation, the quantity of each transportation is small, and the transportation cost is high, which undoubtedly increases the production cost of the thin-walled box and the cast-in-place reinforced concrete. Construction cost of hollow core slabs

Embodiment Construction
[0060] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0061] As shown in the accompanying drawings, the present invention includes an upper plate 1, a surrounding side plate 2, and a lower bottom plate 3. The upper plate 1, the surrounding side plates 2, and the lower bottom plate 3 enclose each other to form a closed cavity thin-walled box, which is characterized in that The above-mentioned upper plate 1, surrounding side plates 2, and lower bottom plate 3 are all assembled by plastic plates 4, and the assembled parts are connected as a whole by connectors 5, and a separable support rod ring is arranged in the cavity of the thin-walled box. At least one of the ring frame 6, the support ring frame 7, the support rod 8 or the support plate 9, and is connected with the inner wall of the plastic sheet 4 of the thin-walled box, the support rod ring frame 6, the support ring frame 7, the support The rod 8 or th...

A plastic thin-wall box includes upper plate, sidewalls and lower plate, all of which combines a close cavity thin-wall box. The said thin-wall box features that upper plate, sidewalls and lower plate are all assembled by plastic plate and the assembled position are contacted into a whole by connecting parts. At least one of the separable supporting pole circle-frame, supporting circle-frame, supporting pole or supporting plate is in the thin-wall box cavity, and contact with the inner-wall of the plastic plate of the thin-wall box. They all have connecting concave and the plastic plate of the connecting concave has reinforcing bar or located part; the reinforcing bar or located part contact with the connecting concave. The present invention is suitable for various cast-in-place reinforced concrete hollow plate, floor slab and roofing.
Description
(1) Technical field [0001] The invention relates to a plastic thin-wall box. (2) Background technology [0002] At present, in the prior art, the hole-forming member of the cast-in-place reinforced concrete hollow slab is a permanent mandrel, such as paper tubes, plastic tubes, metal bellows, hollow form shells, and lightweight materials for mandrels. These tubular mandrels or hollow components are mainly considered to evacuate the concrete and reduce the weight of the hollow slab. 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,...
