Specific embodiment
The utility model is described in further details in the following with reference to the drawings and specific embodiments.
As shown in Figure 1-3, specific embodiment described in the utility model is that a kind of PP high muscle enhances polyethylene wound pipe, packet
It includes the tube body being bonded by 1 spiral winding of strip of sheet material overlap joint and cross-pressure is bonded in the tube body in a manner of same spiral winding
Outer hollow reinforced rib 2, the sheet material 1 include upper clinch 101 and lower clinch 102, and the length of the lower clinch 102 is big
In the length of upper clinch 101；
When actual processing, it can choose clinch and lower clinch length sheet material more uniform than band-like thickness for 1:2, melt
The mutual spiral winding overlap joint bonding of the upper clinch and lower clinch melted, is finally bonded into the tube body of section such as Fig. 1.
The sheet material upper clinch 101 overlap joint be bonded on the posterior segment of lower clinch 102 of adjacent sheet, it is described in
The empty overlap joint of reinforcing rib 2 is bonded on the middle leading portion of lower clinch 102,2 side of hollow reinforced rib and adjacent upper clinch
101 end is in contact bonding.
In order to increase the intensity of hollow reinforced rib, a PP abnormity single-wall corrugated pipe 4 is set in the hollow reinforced rib 2,
Cross section, which is antiparallelogram structure, or its cross section is above a straight bottom, and other sides are symmetrical curved configuration, PP
Special-shaped 4 outsourcing PE coating 3 of single-wall corrugated pipe constitutes hollow reinforced rib 2, and the surrounding of the hollow reinforced rib 2 is fillet knot
Structure.
In order to increase the intensity of hollow reinforced rib, be provided in the hollow reinforced rib 2 it is a plurality of be mutually adhesively fixed it is different
Shape single-wall corrugated pipe 4, a plurality of be mutually bonded is coating 3, the coating 3 on the outside of fixed special-shaped single-wall corrugated pipe 4
The whole package of the special-shaped single-wall corrugated pipe 4 being mutually adhesively fixed a plurality of, 3 outside of coating with special-shaped single-wall corrugated pipe
It is adhesively fixed in the perpendicular long side of 4 bonding planes with tube body.
Since special-shaped single-wall corrugated pipe can arbitrarily internal stress free be bent, and suitable shape may be selected, Wrapping formed
In the process, the height and curvature of hollow reinforced rib can have bigger range of choice, be conducive to the structure for improving tubing
Wall height and the moment of inertia, thus economy enhance the ring stiffness of tubing, meanwhile, a plurality of abnormity single-wall corrugated pipe, which bonds, to be formed
Hollow reinforced rib, structure is stronger and stablizes.It, can be using the single reinforcement knot containing only a bellows for thinner tube body
Structure, the production and processing of single reinforcement structure are easy；It is general using the double muscle structures for containing two bellowss for thicker tube body, process work
Skill is complicated, but structure is more stable.
In order to increase the stability between special-shaped single-wall corrugated pipe, it is equipped between special-shaped single-wall corrugated pipe 4 single with two sides abnormity
The reinforcing rib sheet material 5 that the tube wall of wall bellows bonds.The reinforcing rib sheet material 5 is to bond gluing for two sides abnormity single-wall corrugated pipe
Melten gel cold junction is closed to form.By being bonded so that adjacent special-shaped single-wall corrugated pipe is stably connected with together.
In order to increase stability, two special-shaped single-wall corrugated pipes 4 are provided in the hollow reinforced rib 2, the abnormity is single
The cross section of wall bellows 4 is right-angled trapezium, and two adjacent right-angle sides of the special-shaped single-wall corrugated pipe 4 are adhesively fixed to form increasing
Strong internal-rib.
In order to increase stability, the cross section of the hollow reinforced rib 2 is antiparallelogram structure, the hollow reinforced rib 2
Surrounding be rounded structure.Surrounding be hollow reinforced rib stability that rounded structure and cross section are antiparallelogram structure compared with
It is good.
In order to obtain optimal adhesive effect, the coating 3 includes being modified interlayer 301 and outer casing 302, described to change
Property interlayer 302 and outer casing 301 in side bonds, the special-shaped single-wall corrugated pipe 4 that the modified interlayer 302 will mutually be adhesively fixed
Whole package bonding, 301 outside of outer casing are adhesively fixed with tube body.Such as Fig. 2 specific embodiment two, modified interlayer first will
The special-shaped single-wall corrugated pipe being mutually adhesively fixed integrally wraps up, and then outer casing again wraps up modified interlayer, last outer package
Layer is Nian Jie with tube body.
In order to obtain optimal adhesive effect, one or more is provided in the hollow reinforced rib 2 and is mutually adhesively fixed
Special-shaped single-wall corrugated pipe 4, it is described abnormity single-wall corrugated pipe 4 on the outside of be respectively arranged with modified interlayer 302 and outer casing 301,
The whole package of the special-shaped single-wall corrugated pipe 4 being mutually adhesively fixed is bonded by the modified interlayer 302, modified 302 bottom of interlayer
It is adhesively fixed on the outside of portion with tube body, modified 302 upper outside of interlayer is adhesively fixed with outer casing 301, the outer package
301 both side ends of layer are adhesively fixed with tube body.Such as Fig. 3 specific embodiment three, modified interlayer is first by one or more mutually bonding
Fixed special-shaped single-wall corrugated pipe integrally wraps up, and then outer casing again wraps up modified interlayer top half, last outer package
Layer corner, modified interlayer bottom are Nian Jie with tube body again.
Usual coating uses PE, and internal layer bellows uses PP material.Since PP and PE are two different materials, the two
Between be bonded not enough securely；It is added between PP and PE layers to the preferable modified PE interlayer of the two adhesive type, it can be further
Improve the stability of bonding.And due to will increase cost using modified PE, and whole modified PE costs can be higher, and uses folder
Layer design, it is only necessary to a small amount of modified PE.Simultaneously when PE layer thicker, the PE heat of molten condition is difficult to distribute, can will be interior
The PP bellows softening that portion plays a supportive role, can not form stable hollow reinforced rib, if can using multilayer tectum structure
To effectively improve heat dissipation effect, guarantee the stability of structure.
The application is using mutually overlap joint production winding pipe, hollow reinforced rib are adhered in tube body by single sheet between sheet material
On the thinner part of composition, Inner tubing layers uniform wall thickness consistency ensure that, to save material；And due to upper clinch
The area Nian Jie with lower clinch is larger, is bonded stronger, tube wall tensile strength compared to traditional single sheet side end portion
Preferably.Cladding multilayer PE is constituted after the hollow reinforced rib is connected by one or more PP pipe, and multilayer coating structure solves heat dissipation
Problem can increase cladding thickness according to the design needs, while be conducive to the bonding that clad and PP pipe are solved with lower cost
Problem.
The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, all according to this
The technical spirit of utility model any trickle amendment, equivalent replacement and improvement to the above embodiments should be included in this
Within the protection scope of utility model technical solution.
