Abstract

A cast-in-situ reinforced concrete floor plate comprises reinforced concretes and hole-forming used component, the invention is characterized in that the hole-forming component is a whole component with cavity assembled by the composite components (1) which are arranged with the connecting components (2) for assembling, and the connecting components (2) are rabbets inside or outside the cavity body, the small step, the roll rim or male-female groove of the component. In this way the floor plate is suitable to be used in various cast-in-situ hollow building roofs, building covers, base plates, 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 cast-in-place reinforced concrete floor slab. (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 head seals...
