Abstract

Disclosed are assembling units (1) of members for cast-in-situ reinforced bar concrete pore-forming, which form a chamber of the cast-in-situ reinforced bar concrete integral member through a joining member (2) arranged thereon, wherein at least one end of the assembling unit is provided with an end plate (3), the end plate (3) is provided with male joining members (2) or / and female joining members (2) or / and matched joining members (2). The invention can be applied to various cast-in-situ concrete hollow building slabs, house roofings, foundation slabs, 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 02158263.7, and a title of "a component for forming holes in cast-in-place reinforced concrete". (1) Technical field [0002] The invention relates to a hole-forming 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....
