Embodiment Construction

[0071] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0072] 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. The upper or lower outer wall 2 of the hollow carcass 1 is made of prefabricated board wall 4 and slurry embryo body 5, which are soft and hard laminated, cemented and solidified, and the prefabricated board wall 4 and slurry embryo body 5 are made of inner hard and outer soft laminated, cemented and solidified. Formed, the upper or lower outer wall 2 has reinforcements 6. 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 sam...

Abstract

The invention discloses a field casting reinforced concrete or prestressed reinforced concrete hollow slab which comprises a reinforced concrete, a hollow matrix (1) which is enwrapped and contained in the filed casting reinforced concrete; the hollow matrix (1) is formed by the enclosing of external walls (2), the interior of which is a cavity (3). The field casting reinforced concrete or prestressed reinforced concrete hollow slab is characterized in that precast sidings (4) and slurry green bodies (5) are superposed, soft and hard, and then cemented and hardened to obtain the external wall (2) of the upper part or the lower part of the hollow matrix (1); the precast sidings (4) and the slurry green bodies (5) are superposed, hard inside and soft outside, and then cemented and hardened; the upper part or the lower part of the external wall (2) is provided with a reinforcer (6), thereby being applicable to the filed casting reinforced concrete or the prestressed reinforced concrete hollow slabs, floors, roofs, walls, foundation base plates and bridges and particularly applicable to hollow girderless floors.

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 ...
