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 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...
