Abstract

The present invention relates to a kind of permanent form for filling concrete. It includes upper plate, peripheral side wall and lower bottom plate. Said upper plate, peripheral side wall and lower bottom plate are connected together and formed into a closed hollow cavity form member. It is characterized by that the hollow mould hole of its hollow bar mould is made into the conical form whose upper portion is small and lower portion is large. Said permanent form can be used for in-situ casting reinforced concrete or prestressed reinforced concrete floor, roof, wall body, foundation bedplate and bridge, etc.

Description

[0001] This application is a divisional application of an invention patent application with an application date of October 27, 2003, an application number of 200310104264.3, and a title of "a permanent formwork for concrete filling". (1) Technical field [0002] The invention relates to a permanent formwork 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 plate, the upper plate, the surrounding side walls and the lower bottom plate form a polyhedron cavity. Another ...
