Hollow basin

Abstract

A hollow basin is composed of head plate(1) and side plate(2). Said at least two side plates(2) are integrated with head plate(1), connecting rod(3) is arranged at joint of adjacent edges of side plates, and each member is connected flexibly. It's cheap, simple, convenient and firm. It has better quality and no crack and occupies less space. It can be used for hollow plates, roof, basic baseboard, wall and bridges.

Description

(1) Technical field [0001] The invention relates to a hollow basin. (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, 2001 is ...

Problems solved by technology

Equally, this pot-shaped formwork member, as an integral member, also 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 basin-shaped formwork member and the cast-in-place The construction cost of the reinforced concrete hollow slab, therefore, the development of a new type of hollow basin has been urgently needed
