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. Fig. 1 is a schematic structural 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. As shown in Figure 1, the hole-forming member is a combination part 1 that constitutes a combined cavity-forming integral part, on which are provided joints 2 for combination, shown as a half-side square-round tubular combination part, and can also be three-pointed. Combination parts in the form of one or quarter tubes. Fig....

Abstract

A cast-in-situ reinforced concrete floor plate comprises reinforced concrete 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, the two ends of the composite components (1) are arranged with end plates (3) comprising a basin-shaped composite component, the hole-forming component is obtained by relatively fastening two basin-shaped composite components at the basin opening, the fastened basin opening has a fastening structure and the external shapes of the basin of the basin-shaped composite component are same. The floor plate is suitable to be used by the hollow building roof, building cover, wall, base plate and empty bridge using the cast-in-situ reinforced concrete or prestressed reinforcement concrete, especially suitable to be used by the hollow beamless floor.

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 hollow 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 seal...
