The integral bending of material.
Traditional double wall bellows, outer wall have the shell of the cylinder-shaped thin wall wrinkle of multiple transverse waves, and inner wall is inside and outside
Flat cylindrical shell.Due to wall characteristics in it, determine that it is unable to the curved characteristic of wide-angle, so all the time not
It is applied to the hollow reinforced rib of structured wall popes.
Therefore, it is necessary to a kind of novel double-wall corrugated pipe be provided, to overcome disadvantages mentioned above.
Summary of the invention
Present invention seek to address that the above problem, provides a kind of as the double-wall corrugated of structure-wall pipe material hollow reinforced rib
Pipe is provided with the first ripple protrusion by outer wall layer, and the first ripple raised position that inner wall layer corresponds to outer wall layer is provided with
The double-deck bulge-structure of foldable, extensible second ripple protrusion has stronger compressive property, the second wave in inner wall layer
Foldable, the extensible structure of line protrusion helps to ensure that double-wall corrugated pipe can be needed with the bending of the larger angle of internal stress free
It wants；The outer surface of second ripple protrusion, which is tangential on outer wall layer inner surface and the inflection point of the first ripple convex inner surface, to be helped to add
The support of strong first ripple protrusion；Entire double-wall corrugated pipe solves the problems, such as the prior art, and structure is stronger and stablizes
The technical scheme adopted is as follows：
A kind of double-wall corrugated pipe as structure-wall pipe material hollow reinforced rib, including outer wall layer and inner wall layer, the outer wall
Layer matches and bonding with inner wall layer, and the outer wall layer is formed with several raised, institutes that are alternatively arranged uniform first ripple
It states inner wall layer and is formed with several and be alternatively arranged uniform second ripple protrusion, the second ripple protrusion and the first ripple are convex
It rises corresponding.
Based on the above technical solution, the cross section of the first ripple protrusion is round, ellipse or polygon
Shape.
Based on the above technical solution, the outer surface of the second ripple protrusion be tangential on outer wall layer inner surface with
The inflection point of first ripple convex inner surface.
Based on the above technical solution, the second ripple protrusion is foldable, extensible, and the second ripple protrusion
For round, ellipse or polygon.
Based on the above technical solution, the cross section of the outer wall layer is round, ellipse or polygon.
Based on the above technical solution, the outer wall layer and inner wall layer are all made of PP, PE, EVA, PVC, ABS, modeling
Expect to be made with the mixing material of glass fiber material.
Based on the above technical solution, the bending range of the outer wall layer and inner wall layer is 0~180 degree.
Beneficial effects of the present invention are：Outer wall layer is provided with the first ripple protrusion, inner wall layer corresponds to outer wall layer
First ripple raised position is provided with the double-deck bulge-structure of foldable, extensible second ripple protrusion, has stronger resistance to compression
Performance, foldable, the extensible structure of the second ripple protrusion in inner wall layer, helps to ensure that double-wall corrugated pipe can be without interior
The bending of the larger angle of stress needs；The outer surface of second ripple protrusion is tangential on outer wall layer inner surface and the first ripple is convex
The inflection point for playing inner surface helps to reinforce the support of the first ripple protrusion；Entire double-wall corrugated pipe solves the difficulty of the prior art
Topic, structure is stronger and stablizes.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples：
As shown in Figures 1 to 5, a kind of double-wall corrugated pipe as structure-wall pipe material hollow reinforced rib of the present embodiment, packet
Include outer wall layer 2 and inner wall layer 1, the outer wall layer 2 matches and bonding with inner wall layer 1, and the outer wall layer 2 is formed with several
A to be alternatively arranged uniform first ripple protrusion 21, the inner wall layer 1 is formed with several and is alternatively arranged uniform second ripple
Protrusion 11, the second ripple protrusion 11 are corresponding with the first ripple protrusion 21.
Preferably, the cross section of the first ripple protrusion 21 is round, ellipse or polygon.
Preferably, the outer surface of the second ripple protrusion 11 is tangential on 2 inner surface of outer wall layer and the first ripple protrusion 21
The inflection point of inner surface facilitates the support for reinforcing the first ripple protrusion.
Preferably, the second ripple protrusion 11 is foldable, extensible, and the second ripple protrusion 11 is round, ellipse
Or polygon.
The second ripple protrusion is consistent with the protrusion direction of the first ripple protrusion.
Preferably, the cross section of the outer wall layer 2 is round, ellipse or polygon.
Further, the outer wall layer 2 and inner wall layer 1 are all made of PP, PE, EVA, PVC, ABS, plastics and glass fiber material
Mixing material is made.
Further, the bending range of the outer wall layer 2 and inner wall layer 1 is 0~180 degree.
As shown in Figure 4 and Figure 5, double-wall corrugated pipe cross section is isosceles trapezoid or right-angled trapezium, passes through two trapezoidal sides
Side provides support force, and after being rolled in heated package melten gel and by pinch roller, the cross-sectional deformation of double-wall corrugated pipe is small, width and high
Ratio between degree improves the ring stiffness of double-wall corrugated pipe, improves its integral bending close to 1.By double-wall corrugated pipe
Cross section is fabricated to isosceles trapezoid or right-angled trapezium, by the plane of trapezium base, can increase double-wall corrugated pipe and tubing
Contact area improves connective stability between the two, and then improves bonding strength between the two.
Concrete example is described as follows：
| Type | Size | Raw material | Structure is high | Pitch | Meter Chong | Ring stiffness |
| Single-wall corrugated pipe | Φ80mm | PP | 5.0mm | 7.4mm | 580g | 10.2 |
| Double-wall corrugated pipe | Φ80mm | Outer wall PP | 6.5mm | 9.0mm | 400g | 10.5 |
By upper table this it appears that：In the case of the single-wall corrugated pipe and double-wall corrugated pipe of same outer diameter, make
With double-wall corrugated pipe under the early period that ring stiffness improves, unit rice weight 220g can be effectively reduced, with 800 specification of structured wall popes
For：Standard pitch 120mm, normal inner diameter 800mm use Φ 80mm specification double-wall corrugated pipe as in the case where reinforced pipe,
Every structured wall popes (6 meters) can reduce weight 24.5kg；It can be seen that its energy-saving effect is apparent.
The present invention is described by way of example above, but the present invention is not limited to above-mentioned specific embodiment, all to be based on
Any changes or modifications that the present invention is done are fallen within the scope of the claimed invention.
