Embodiment Construction

[0041] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0042] The present invention, as shown in the accompanying drawings, is characterized in that the hole-forming member is a combination component 1 that constitutes an integral cavity-forming component, and the combination component 1 is provided with a connecting piece 2 for combination. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is an assembly part, and 2 is a connecting piece. In each accompanying drawing, those with the same number have the same description. Such as figure 1As shown, the hole-forming member is a combined component 1 that constitutes an integral component for forming a cavity, on which there are joints 2 for combining with each other. The figure shows a half-side square-round tubular combined component, which can also be one-third or one third. Quarter-tubu...

Abstract

A hole-forming member for in-situ casting the reinforced concrete is such a one used to combine a whole cavity. The connecting parts are used to combine two or more said members to form a hollow thin-wall member. Its advantages are high strength, low cost and high construction speed.

Description

(1) Technical field [0001] The invention relates to a hole-forming 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 head seals both ends of the hard thin-walled tube to form a closed cavity. The hard thin-walled tube wall is composed of a matrix and a cementitious material. The matrix can be glass fiber or carbon fiber or organic fiber or non-woven fabric or Fiber ...
