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, develops a kind of new-type hollow member that fills concrete and has been urgently needed

Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] As shown in the accompanying drawings, the present invention includes an upper plate 1 and surrounding side plates 2. The upper plate 1 and the surrounding side plates 2 form a basin shape, and the feature is that the surrounding side plates 2 are spliced ​​by at least one side plate 2. , the splicing parts of the ring-shaped surrounding side panels 2 have side panel interface parts 6 connecting the edges of adjacent side panels. As shown in FIG. 9 , the surrounding side panels 2 are spliced ​​by side panels 2 , and the ring-shaped peripheral side panels 2 are spliced ​​with side panel interface pieces 6 connecting adjacent side panels.

[0056] The present invention is also characterized in that there is a connecting piece 3 at the junction between the side plate 2 and the side plate 2 . As shown in FIG. 16 , there is a connecting piece 3 at th...

Abstract

The present invention relates to a hollow member for filling concrete. It includes upper plate and peripheric side plate. Said upper plate and peripheric side plate are formed into the form of basin. It is characterized by that the described peripheric side plate is made up by using four side plates and making them be connected together and made into an annular peripheric side plate. Said hollow member can be used for in-situ casting various reinforced concrete or prestressed reinforced concrete hollow plates, hollow floor, roof, foundation bedplate, wall body and open-web bridge, etc.

Description

(1) Technical field [0001] The invention relates to a hollow member for concrete filling. (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...
