Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043]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 1 As 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 cast-in-situ reinforced concrete floor comprises reinforced concrete and hole-forming used component. The invention is characterized in that the hole-forming component is a whole component with cavity which is combined by the combination component (1). The combination component (1) is provided with a connecting piece (2) for combination. Two ends of the combination component (1) are provided with end plates (3) to form a basin-shaped component with five surfaces. The external surface of the basin-shaped component is extended with a connecting piece (2). The cast-in-situ reinforced concrete floor is suitable to be used for various hollow building roofs, building covers, walls, base plates and hollow bridge of the cast-in-situ reinforced concrete or prestressed reinforcement concrete, and is especially suitable to be used for the hollow beamless floor cover.

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...
