Embodiment Construction

[0057] The present invention will be further described below in conjunction with drawings and embodiments.

[0058] As shown in the drawings, the present invention includes a pipe body 1, which is a corrugated pipe 1, and is characterized in that there is at least one transverse groove 2 on the pipe body 1. figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In each accompanying drawing, 1 is a pipe body, 2 is a transverse groove, and if the number is the same, its description is the same. Such as figure 1 As shown, there are two transverse grooves 2 on the pipe body 1.

[0059] The present invention is also characterized in that at least one section of branch pipe 3 protrudes from the pipe body 1, and the branch pipe 3 is a corrugated pipe. figure 2 It is a structural schematic diagram of Embodiment 2 of the present invention. A branch pipe 3 protrudes from the pipe body 1, and the branch pipe 3 is a corrugated pipe.

Abstract

The light pipe for filling steel reinforced concrete is corrugated pipe with at least one transverse notch. The in-situ cast concrete enters the transverse notch to form in-situ cast concrete rib to strengthen the transverse rigidity and strength greatly and reduce 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...
