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

Embodiment Construction

[0067] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0068] As shown in the accompanying drawings, the present invention includes a basin top plate 1 and a basin side plate 2, and is characterized in that at least two basin side plates 2 are integrated with the basin top plate 1, and the adjacent sides of the basin side plates 2 are connected to each other to form an annular basin wall , the basin top plate 1 and the annular basin wall form an open hollow basin, the joint of the basin side plate 2 is a hinged connection, and there is a connection lamination 9 between the two inner walls. Such as Figure 16 As shown, a plurality of basin side panels 2 and basin top panel 1 are integrated as a whole. It is a hinged connection, and there is a connection lamination 9 between the two inner walls.

[0069] The present invention is also characterized in that the open hollow basin has supporting feet 13 . Such...

Abstract

The present invention relates to a kind of hollow basin. It includes basin top plate and basin side plate, and is characterized by that at least two basin side plates and basin top plate are connectedinto one whole body, the adjacent sides of said basin side plates are formed into ring-shaped basin wall, the basin top plate and ring-shaped basin wall are formed into an open hollow basin. Said hollow basin can be used for in-situ casting reinforced concrete or prestressed reinforced concrete hollow slab, hollow floor, roof, foundation bedplate and wall body, etc.

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 ...
