Problems solved by technology

But the hollow tube member that above-mentioned various methods make is all more difficult at the seam joint part, and seam quality is poor, and the seam joint part overlap is not firm, thereby the strength of hollow pipe member, integrality are lower, and production efficiency is lower. Low

Embodiment Construction

[0066] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0067] As shown in the accompanying drawings, the present invention includes a reinforced concrete 1 and a hollow pipe 2. The hollow pipe 2 is wrapped in the reinforced concrete 1. The hollow pipe 2 includes a pipe body 3 and a pipe end seal 4. The pipe end seal 4 seals the pipe body 3 to form A closed hollow tube 2, the tube wall of the tube body 3 has at least one joint joint 5 cemented and joined by slurry embryo body, there are longitudinal cast-in-place concrete ribs 6 between the hollow tubes 2, and there are cast-in-place concrete ribs 6 between the ends of the hollow tubes 2. The rib 7 between the concrete ends is characterized in that there is a prefabricated support member 8 which is superimposed and glued with the joined embryo body at the joint of the embryo body of at least one joint 5 . Fig. 1 is a schematic structural diagram of Embodimen...

Abstract

The invention relates to cast-in-site concrete hollow slob. It includes reinforced concrete, hollow tube embedded in the former. The hollow tube includes tube body and tube end seal which are formed sealed one. The tube wall of the tube body is set at least one binding seam. There is vertical cast-in-site concrete rib between the hollow tube, and its end bay rib between the tube ends. Its feature is that embryo proper joining with at least one binding seam is set embryo supporting component. Thus the joint close part has easy and good quality jointing; the corresponding hollow tube component has high strength, good entirety, once molding, high production efficiency while producing which overcomes the defect in existing technology, reaches the purpose of the invention.

Description

(1) Technical field [0001] The invention relates to a cast-in-place concrete hollow slab. (2) Background technology [0002] At present, in many buildings, the large-span and large-bay frame structure adopts the cast-in-place hollow floor technology, especially the beamless floor technology, which has the advantages of shortening the construction period, reducing costs, increasing the use space of the building, reducing the weight, Good anti-seismic performance and other advantages. The hole-forming components used in beamless slabs are permanent mandrels, such as paper tubes, plastic tubes, metal hollow tubes, hard thin-walled tubes, etc. These tubular mandrels or components are mainly considered to evacuate the concrete and reduce the weight of the floor slab. Among them, paper tubes, plastic tubes, and metal hollow tubes are rarely used because of their high cost. At present, most of the projects use hard thin-walled tubes, such as the "fiber-reinforced thin-walled tub...
