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 part 1 that constitutes an integral member of the cavity, the combination part 1 is provided with a connecting piece 2 for combination, and the two ends of the combination part 1 are provided with The end plate 3 constitutes a basin-shaped composite part, and the hole-forming member is formed by two basin-shaped composite parts that are buckled relatively at the mouth of the basin. The same or similar, pot-shaped combination parts have chamfers, arc corners. 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. As shown in Figure 1, the hole-forming member is a combination part 1 that constitutes a combined ca...

Abstract

A member for perforating cast-in-situ reinforced concrete is composed of assembled part(1), connector(2) and end plate(3). Said connector(2) is arranged on said assemble part(1), said end plates(3) are arranged at both ends of said assemble part(1) to form into basin-shaped assemble device, said member for perforating is buckled by said two basin-shaped assembled parts(1) with butt-joint structure, said basin-shaped assembled parts are same or similar shaped and have chamber and arc angle. It can be used for various hollow and beamless building roofs of cast-in-situ reinforced concrete or pre-stressed reinforced concrete, basic baseboard, wall and 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....
