Abstract

A member for in-situ casting the reinforced concrete is composed of two halves, which are fastened together to form a hollow thin-wall member used for in-situ casting hollow floor slab, roof, wall, etc. Said member is made up by die pressing. Its advantages are high strength, low cost, and convenient transportation.

Description

(1) Technical field [0001] The invention relates to a component for cast-in-place reinforced concrete. (2) Background technology [0002] 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-walled tube are closed to form a closed cavity. The hard thin-walled tube wall is composed of a carcass and a cementing material. The carcass can be glass fiber or carbon fiber or organic fiber or non-woven fabric or fiber For braided fab...
