As shown in Figure 1-3, specific embodiment described in the utility model is a kind of poly- second of hollow multi-cavity PP high muscle enhancing
Alkene winding pipe, cross-pressure glues including the tube body being bonded by band-like 1 spiral winding of profile overlap joint and in a manner of same spiral winding
The hollow reinforced rib 2 outside the tube body is closed, the profile 1 is convex structure, and the profile 1 includes clinch 102, convexity
Portion 101, the clinch 102 are located at middle 101 two sides of protrusion, and the thickness of the middle protrusion 101 is greater than the thickness of clinch 102,
At least two hollow cavity structures 103 are provided in the middle protrusion 101；It is hollow since middle protrusion uses multi-cavity structure
Complex root support column it has been equivalent to more among cavity, the stability of middle protrusion greatly improves.
In order to increase stability, the clinch 102 of the profile 1 and the clinch 102 of adjacent profiles 1 pass through melt layer 3
It overlaps and bonds with hollow reinforced rib 2, the end that 2 two sides of hollow reinforced rib pass through protrusion 101 in melt layer 3 and adjacent profiles 1
Head overlap joint bonding, the melt layer 3 are that clinch 102 and the bonding melten gel cold junction of hollow reinforced rib 2 form.
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 the abnormity single-wall corrugated pipe 4 different with two sides
The reinforcing rib profile 6 that the tube wall of shape single-wall corrugated pipe bonds.The reinforcing rib profile 6 is bonding two sides abnormity single-wall corrugated pipe
Bonding melten gel cold junction 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.Surrounding is rounded structure and cross section is preferable for the hollow reinforced rib stability of antiparallelogram structure.
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 5 includes being modified interlayer 502 and outer casing 501, described to change
Property interlayer 502 and outer casing 501 in side bonds, the special-shaped single-wall corrugated pipe 4 that the modified interlayer 502 will mutually be adhesively fixed
Whole package bonding, 501 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, it is provided with one or more in the hollow reinforced rib 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 502 and outer casing 501, institute
State the whole package bonding of special-shaped single-wall corrugated pipe 4 that modified interlayer 502 is mutually adhesively fixed one or more, the modified folder
502 bottom outside of layer are adhesively fixed with tube body, and modified 502 upper outside of interlayer is adhesively fixed with outer casing 501, described
501 both side ends of outer casing are adhesively fixed with tube body.Such as Fig. 3 specific embodiment three, modified interlayer first will mutually be adhesively fixed
Special-shaped single-wall corrugated pipe integrally wrap up, then outer casing again will modified interlayer top half package, last outer casing side
Angle, modified interlayer bottom are Nian Jie with tube body again.
Usual coating uses PE, and internal layer uses PP material.It is viscous therebetween since PP and PE are two different materials
It connects not enough securely；It is added between PP and PE layers to the preferable modified PE interlayer of the two adhesive type, can be further improved viscous
The stability connect.And due to will increase cost using modified PE, and whole modified PE costs can be higher, and is set using interlayer
Meter, it is only necessary to a small amount of modified PE.Simultaneously when PE layers thicker, the PE heat of molten condition is difficult to distribute, and can play inside
The PP bellows of supporting role softens, and stable hollow reinforced rib can not be formed, if can have using multilayer tectum structure
Effect improves heat dissipation effect, guarantees the stability of structure.
The application makes thickening type winding pipe using the profile of convex structure, and hollow reinforced rib is for filling up clinch
Thickness is more easier to cool down after guaranteeing to bond overlap joint while meeting national standard thickness；At the same time, moreover it is possible to substantially save
Material reduces production cost, while also reducing the weight of product, can save transportation cost；Protrusion uses multi-cavity in simultaneously
Body structure greatly improves the stability of middle protrusion；The hollow reinforced rib urged using special-shaped single-wall corrugated pipe is conducive to improve pipe
The structural walls height and the moment of inertia of material, thus economy enhance the ring stiffness of tubing, while structure is stronger and stablizes.
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.
