Abstract

The invention relates to a hole-forming component of cast-in-situ reinforced concrete which is characterized in that the hole-forming component is of a composite part (1) which is used for forming a combination cavitation integral component. The composite part (1) is provided with an inosculating part (2) which is used for combination. The inosculating part (2) is of a turned edge or a composite groove of a tenon, a small step and a component in or out of a cavity, therefore, the invention is suitable for various hollow floor slabs, roofs, wall bodies, foundation slabs and vierendeel bridges which are made of cast-in-situ concrete.

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....
