Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0064] As shown in the accompanying drawings, the present invention includes an upper plate 1, surrounding side walls 2, and a lower plate 3, and the upper plate 1, surrounding side walls 2, and lower plate 3 form a closed cavity formwork, which is characterized in that the closed cavity The cavity formwork is all assembled by prefabricated components. The prefabricated components constitute the upper plate 1 or / and the surrounding side walls 2 or / and the lower plate 3. The prefabricated components are at least two prefabricated plates 4, and there are connections between the prefabricated plates 4. The pieces 5 are connected to each other, and the connecting piece 5 is an L-shaped corner connecting piece. Fig. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is an upper plate, 2 is a surroun...

Abstract

Disclosed is a hollow concrete shuttering member for concrete filling, which comprises an upper board (1), the peripheral side panels (2) and a lower board (3), wherein the upper board (1), the peripheral side panels (2) and the lower board (3) enclose a closed hollow shuttering, characterized in that all of the hollow shuttering members are pasted from prefabricated panels (3), the precast members form the upper board (1) or / and peripheral side walls (2) or / and lower board (3), the precast members are at least two prefabricated panels (4), the prefabricated panels (4) are connected into an integrality through a connecting member (5). The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of December 9, 2003, an application number of 200310121939.5, and a title of “A Cavity Formwork Member for Concrete Filling”. (1) Technical field [0002] The invention relates to a cavity formwork component for concrete filling. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure, and the lightweight permanent tire mold filled in it includes hollow tubes and cavity formwork components. 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 exa...
