Embodiment Construction

[0078] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0079] As shown in the accompanying drawings, the present invention includes a reinforced concrete 1 and a hollow carcass 2. The hollow carcass 2 is wrapped in the reinforced concrete 1. The outer wall 3 encloses the hollow carcass 2 with a cavity 4. The hollow carcass 2 is connected to each other. The cast-in-place reinforced concrete ribs 5 formed by reinforced concrete 1 are characterized in that at least one surface of the hollow carcass 2 is a wet embryo body 6 when it is formed, and the slurry body 6 is hung upside down on the mold. The slurry embryo body 6 has at least one prefabricated strip-shaped reinforcing rib 7 superimposed under the embryo body to support the embryo body. In each attached drawing, 1 is reinforced concrete, 2 is hollow carcass, 3 is outer wall, 4 is cavity, 5 is cast-in-place reinforced concrete rib, 6 is embryo body of wet...

Abstract

The invention is a cast-in-site concrete hollow slab, comprising reinforced concrete and hollow bodies, where the hollow bodies are wrapped in the reinforced concrete, the bottom outer wall of the hollow body is equipped with support foot, and the hollow body is formed by outer walls, and cast-in-site reinforced concrete rib is arranged between every two adjacent hollow bodies, and it is characterized in that: at least one surface of the hollow body is composed of wet pulp body when the hollow body is moulded, the pulp body is hung upside down on the mould and equipped with at least one prefabricated strip reinforcing bar stacked under to support the body. Thus, it has features of simple structure, high intensity, large rigidity, excellent deformation and vibration resistances, high construction speed, etc, and it is applied to cast-in-site reinforced concrete or prestressed reinforced concrete hollow building covers, roofs, wall bodies, foundation soleplates and bridges, especially hollow, beam-free building covers.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] 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 walls and the lower bottom form a polyhedral cavity. Another example is that the patent No. is ZL00203695.9, and the name is called "combined concrete hidden rib floor slab" utility model patent, which discloses a formwork member in its specification, which can be solid or hollow, and its sh...
