Description

PP double-high-rib winding structure pipe

Technical Field

The utility model belongs to the technical field of the winding tubular construction, concretely relates to two high muscle winding arrangement pipes of PP.

Background

The corrugated pipe is a novel pipe with an outer wall of an annular structure and a smooth inner wall, the winding corrugated pipe is a pipe with unlimited length obtained in a continuous winding mode, and is a novel light pipe which mainly uses high-density polyethylene (HDPE) as a raw material, the outer wall is of an annular corrugated structure, and the annular rigidity of the pipe is greatly enhanced, so that the resistance of the pipe to soil load is enhanced, and the corrugated pipe has the characteristics of light weight, high pressure resistance, good toughness, quick construction and the like, and is applied to replace concrete pipes and cast iron pipes. But traditional two high muscle winding arrangement pipes of PP add man-hour directly with cavity or have the winding pipe of strengthening rib structure adopt the PP glue adhesion of high bonding strength on tubular product, this kind of processing mode is convenient, with low costs, but the winding pipe extrusion force that the inboard received when the bending can cause fold and recoil power when too big, directly leads to the bonding department to appear space or fold, influences the bonding strength in later stage.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose: the utility model aims at providing a two high muscle winding arrangement pipes of PP can reduce or eliminate the inboard extrusion stress of winding pipe, and reinforcing adhesion strength improves the tubular product quality to the not enough of prior art existence.

The technical scheme is as follows: in order to realize the purpose of the utility model, the utility model discloses a technical scheme as follows:

a PP double-high-rib winding structure pipe comprises a winding body and a pipe, wherein a spiral groove is formed in the surface of the pipe, the winding body is wound in the spiral groove in the surface of the pipe to form an outer corrugated shape, and a notch is formed in the bottom of the winding body; the winding body is of a cavity structure, and reinforcing ribs are arranged in the cavity.

Further, the cross section of the winding body cavity is triangular, rectangular or arched.

Further, the height of the cut is smaller than the depth of the spiral groove, and the width of the cut is 0.5-1 mm.

Further, the adjacent incisions are spaced apart by 20-60 mm.

Further, the spiral angle of the winding body is 30-60 degrees.

Furthermore, the reinforcing ribs are vertical, and the number of the reinforcing ribs is 1-2.

Furthermore, the reinforcing rib is T-shaped, two transverse ends of the reinforcing rib are connected with two ends of the winding body cavity, and the lower end of the reinforcing rib is connected with the bottom of the winding body cavity.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is following:

the utility model discloses set up the incision in the inboard of winding body, can effectively avoid the winding body to lead to the fact follow-up bonding department to split owing to receiving the extrusion force at spiral winding in-process inboard, reinforcing adhesion strength improves the tubular product quality.

Detailed Description

The present invention will be further clarified by the following embodiments, which are implemented on the premise of the technical solution of the present invention, with reference to the attached drawings, and it should be understood that these embodiments are only used for illustrating the present invention and are not used for limiting the scope of the present invention.

As shown in figure 1, the PP double-high-rib winding structure pipe comprises a winding body 1 and a pipe 2, wherein a spiral groove 3 is formed in the surface of the pipe 2, the winding body 1 is wound in the spiral groove 3 in the surface of the pipe 2 to form an outer corrugated shape, and a notch 4 is formed in the bottom of the winding body 1. The winding body 1 is of a cavity structure, and the section of the cavity is triangular, rectangular or arched. The present embodiment is illustrated by a triangle and provides a schematic diagram, and does not mean that the cross-sectional shape of the winding body 1 is limited to a triangle.

As shown in figures 2 and 3, the notches 4 are formed by placing a baffle plate at intervals when the winding body 1 is subjected to thermoplastic processing, the notches 4 are of an integral structure with the winding body 1, the height of each notch 4 is smaller than the depth of each spiral groove 3, the width of each notch 4 is 0.5-1mm, and the interval between every two adjacent notches 4 is 20-60 mm. According to the prior knowledge, when winding body 1 spiral winding is on 2 surfaces of tubular product, the part below the neutral line of winding body 1 can fold inwards and receive the compression, when compressive force reaches the limit, the root loses stability and forms extrusion stress, the setting of incision 4 can be when winding body 1 root is gathered together, winding body 1 of incision 4 both sides is to incision 4 department compression, winding body 1 root can not receive the extrusion force and can not lose stability naturally and cause follow-up bonding department to split, the height that highly is less than helicla flute 3 of incision 4 makes in the whole helicla flute 3 that imbeds of incision 4 part of winding body 1 root, do not influence the bonding.

In order to reduce the excessive inner pressing force of the winding body 1 due to the spiral winding, it is preferable that the helix angle of the winding body 1 is smaller, but in order to form an effective corrugated winding structure, it is also necessary to increase the helix angle. Therefore, the helix angle of the winding body 1 of the utility model is between 30 degrees and 60 degrees.

As shown in fig. 4, a reinforcing rib 5 is additionally arranged inside the cavity of the winding body 1 to enhance the strength of the whole winding body 1. The reinforcing ribs 5 are generally vertical and the number is 1-2. Or as shown in fig. 5, the reinforcing rib 5 is T-shaped, the two transverse ends are connected with the two ends of the cavity of the winding body 1, and the lower end is connected with the bottom of the cavity of the winding body 1.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
