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

[0068] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0069] As shown in the accompanying drawings, the present invention includes a pot top plate 1 and a pot side plate 2, and is characterized in that at least two pot side plates 2 are integrated with the pot top plate 1, and the adjacent sides of the pot side plates 2 are connected to each other to form an annular basin wall The pot top plate 1 and the annular pot wall form an open hollow pot, and there is a hinge 10 or a hinge bar 11 between at least one pot top plate 1 or / and at least one pot side plate 2 . As shown in Figure 17, a plurality of pot side plates 2 and pot top plate 1 are integrated as a whole. Hinge 10 and hinge bar 11 are respectively arranged between basin side plate 2.

[0070] The present invention is also characterized in that the open hollow basin has supporting feet 13 . As shown in Figure 19, its described open hollow pot has s...

Abstract

The invention relates to hollow basin. It includes basin upper plate and side plate. Its feature is that at least two side plates and upper plate form a whole. The side plate adjacent edges are connected with each other to form annular basin wall which is formed opening hollow basin with the upper plate. Hinge or link bar is set between at least one upper plate or / and at least one side plate. The invention can be used in various cast-in-site or pre-stress reinforced concrete hollow slab, hollow storey cover, house cover, sole plate, 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 ...
