Abstract

The invention relates to a member for cast-in-place reinforced concrete, which is characterized in that two half-edge parts (1) are buckled and fixed to form the member, and at least one half edge part (1) is provided with a groove (4); and at least one half edge part (1) is provided with a buckling part (10), and is of an turned edge, or a male and female groove or a snap buckle. The invention is suitable for use in various cast-in-place concrete hollow floors, roofs, foundation floors, walls and hollow bridges.

Description

[0001] This application is a divisional application of an invention patent application with an application date of December 22, 2002, an application number of 021582661, and a title of "a component for cast-in-place reinforced concrete". (1) Technical field [0002] The invention relates to a component for cast-in-place reinforced concrete. (2) Background technology [0003] At present, in the prior art, the hole-forming components of the cast-in-place hollow floor slab are permanent mandrels, such as paper tubes, plastic tubes, metal bellows, and lightweight materials for mandrels. These tubular mandrels or components are mainly considered to evacuate the concrete and reduce the weight of the floor slab. For example, the patent No. ZL99249775.8 applied by the applicant is a utility model patent named "fiber-reinforced thin-walled tube for filling cast-in-place reinforced concrete". It consists of a hard thin-walled tube and plugs at both ends. The two ends of the hard thin...
