Embodiment Construction

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

[0064] As shown in the drawings, the present invention includes an upper plate 1, a surrounding side wall 2, a lower plate 3. The upper plate 1, a surrounding side wall 2, and a lower plate 3 enclose a closed cavity mold shell, which is characterized in that the closed cavity The cavity mold shell 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 the prefabricated plates 4 include an upper plate 1. A lower board 3, surrounding side walls 2, upper board 1 or / and lower board 3 protruding steel bars, upper board 1 is thicker than surrounding side walls 2 or / and lower board 3. Fig. 1 is a schematic structural diagram of Embodiment 1 of the present invention. In the drawings, 1 is the upp...

Abstract

The shuttering member for filling concrete includes one upper slab, side walls and one lower slab, which form one closed cavity. The shuttering member features that the closed cavity shuttering is spliced with at least two prefabricated parts, each of which includes one relatively thick upper slab, one lower slab and side walls with steel bars extending from the upper slab and / or the lower slab. The present invention is suitable for in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.

Description

[0001] This application is a divisional application for an invention patent application whose application date is December 9, 2003, the application number is 200310121939.5, and the name is "a cavity mold shell member for concrete filling". (1) Technical field [0002] The invention relates to a cavity mold shell component for concrete filling. (2) Background technology [0003] At present, cast-in-situ concrete hollow floor is a widely used floor structure, and the light permanent tire mold filled in it has hollow tubes and cavity mold shell components. For example, the applicant applied for a patent number ZL99249798.1 on November 29, 1999, 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, the upper plate, the surrounding side walls and the lower bottom enclose a polyhedral cavity. Another example is the applicant...
