Problems solved by technology
However, this kind of thin-walled box formwork member is an integral thin-walled box member, and the thin-walled box formwork member is easy to be damaged during production stacking, transportation and installation construction, especially in the transportation process, and it is not easy to damage after damage. Repair, the wall surface cannot be disassembled and replaced. At the same time, it 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 cost of the thin-walled box and the construction cost of the cast-in-place reinforced concrete hollow slab.

The thin wall plastic box includes one upper plate, side plates and one lower plate, which enclose to form one sealed cavity. The thin wall plastic box features that it is formed with plastic plates connected with connectors in the joints, and each of the connectors comprises one strip and one groove with guide track for the strip to be inserted in and has slipping preventing part(s) in the strip and / or the groove. The present invention is suitable for in-situ cast or pre-stressed reinforced concrete floor slab, roof, wall, foundation slab and bridge, especially flat floor slab.
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,...
