Problems solved by technology

Such as metal bellows, which is formed by metal winding, has the advantages of high strength, good anti-deformation, good anti-vibration performance, and convenient construction and transportation. The tubular concrete in the center of the corrugated pipe has been evacuated, and there are cast-in-place concrete ribs along the longitudinal direction of the pipe, while the reinforced concrete has been evacuated by the metal bellows components in the transverse direction, so there is a large difference in rigidity between the two directions of the cast-in-place hollow slab, which becomes The cast-in-place reinforced concrete hollow one-way slab has the disadvantages of large consumption of reinforced concrete, heavy weight, poor seismic performance, and large difference in two-way stiffness.

Embodiment Construction

[0045]The present invention will be further described below in conjunction with drawings and embodiments.

[0046] As shown in the drawings, the present invention includes a pipe body 1, which is a corrugated pipe body, and is characterized in that there is at least one protruding module 2 on the corrugated pipe body 1, and the module 2 is a corrugated module. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a bellows body, and 2 is a protruding module. In each accompanying drawing, those with the same number have the same description. Such as figure 1 As shown, there are multiple protruding modules 2 on the bellows body 1 . figure 2 It is a structural schematic diagram of Embodiment 2 of the present invention, and its module 2 is a corrugated module.

[0047] The present invention also lies in that the corrugations on the bellows body 1 and the corrugated module 2 are positive corrugations, oblique ...

Abstract

The light pipe for filling in-situ cast steel reinforced concrete is corrugated pipe with at least one protrudent block. The corrugated pipe with protrudent block reduces the consumption of concrete in floor board and dead weight of floor board, strengthens the vibration strength, reduces the longitudinal rigidity and reduces the difference of rigidity in two directions. The present invention has high strength, high deformation and vibration resistance, convenient transportation and other features. The present invention is suitable for use in in-situ cast hollow beam-less reinforced concrete floor board as well as roofing, base board, wall and hollow bridge.

Description

(1) Technical field [0001] The invention relates to a lightweight pipe for filling cast-in-place reinforced concrete. (2) Background technology [0002] 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. Such as metal bellows, which is formed by metal winding, has the advantages of high strength, good anti-deformation, good anti-vibration performance, and convenient construction and transportation. The tubular concrete in the center of the corrugated pipe has been evacuated, and there are cast-in-place concrete ribs along the longitudinal direction of the pipe, while the reinforced concrete has been evacuated by the metal bellows components in the transverse direction, so there is a large diff...
