Embodiment Construction
[0070] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0071]As shown in the accompanying drawings, the present invention includes reinforced concrete and a hollow carcass 1. The hollow carcass 1 is wrapped in the cast-in-place reinforced concrete. The hollow carcass 1 is formed by an outer wall 2 and a cavity 3 is inside. At least one side outer wall 2 of the hollow carcass 1 is made of prefabricated panel wall 4 and slurry embryo body 5, which are soft and hard laminated, cemented and hardened, and there are reinforcements 6 in the superimposed layer of slurry embryo body 5. In the accompanying drawings, 1 is the hollow carcass, 2 is the outer wall, 3 is the cavity, 4 is the prefabricated board wall, and 5 is the slurry body. In the following drawings, those with the same number have the same description. Such as figure 1 As shown, the hollow carcass 1 is formed by enclosing the outer wall 2, and there i...

The invention provides a cast-in-place reinforced concrete or prestressed reinforced concrete hollow core slab, comprising reinforced concrete and a hollow core matrix (1), wherein, the hollow core matrix (1) is wrapped inside the cast-in-place reinforced concrete and is enclosed by an outer wall (2), and the inner part of the hollow core matrix is a hollow cavity (3). The cast-in-place reinforced concrete or prestressed reinforced concrete hollow core slab is characterized in that the lateral surface outer wall (2) on opposite surfaces of the hollow core matrix (1) is formed by coinciding and cementing as well as hardening a prefabricated plate wall (4) and a ground paste blank body (5) in a way of flexibility and hardness, and a reinforcing object (16) is arranged inside the lamination layer of the ground paste blank body (5). The cast-in-place reinforced concrete or prestressed reinforced concrete hollow core slab is applicable to hollow core slabs, floor systems, roofs, wall bodies, foundation slabs and bridges of cast-in-place reinforced concrete or prestressed reinforced concrete, particularly hollow flat slabs.
Description
[0001] This application is a divisional application of an invention patent application with an application date of August 11, 2004, an application number of 200410155218.0, and a title of "a hollow matrix for filling cast-in-place concrete". (1) Technical field [0002] The invention relates to a hollow slab of cast-in-place reinforced concrete or prestressed reinforced concrete. (2) Background technology [0003] At present, the cast-in-place concrete hollow floor is a widely used floor structure. The lightweight permanent tire molds filled in it include various hollow tubes and boxes, and the boxes are hollow or solid. For example, the patent No. ZL99249798.1, which the applicant applied for on November 29, 1999, is a utility model patent named "fiber-reinforced thin-walled member for reinforced concrete filling", which discloses a thin-walled formwork member, including an upper plate, The surrounding side walls, the lower bottom, and the upper plate, the surrounding side ...
