Abstract
The utility model discloses a kind of PVC profile hollow wound pipes, including two structure bands arranged side by side, it is connected between two structure bands by melten gel, and carbon cloth and aramid layer are successively covered in two structure strip surfaces, structure band successively includes the first cuboid, the second cuboid and third cuboid from left to right, three cuboids are hollow structure, are all provided with X-shaped ribs in the hollow structure of the first cuboid and third cuboid, are circular hollow at X-shaped ribs crossover node.In the two sides of hollow, rectangular body, the cuboid containing the hollow ribs of X-shaped is set, the tubing bearing capacity enhancing after making winding, and hollow ribs can deal with different load arrangement variation, so that tubing is not easy diagonal distortion under external force, to further increase tubing bearing capacity；Using the good tensile strength of carbon cloth, tubing tension and shock resistance can be enhanced；It using the good self-lubrication of aramid layer, can prevent tube wall from being galled by foreign object, improve tubing wearability.
Description
Technical field
The utility model relates to plastic pipe technical field, in particular to a kind of PVC profile hollow wound pipe.
Background technique
PVC hollow wound pipe is to produce structure band using polyvinyl chloride resin as raw material through extruder and mold, then utilize
Structure band is wound in tubing by Wiring apparatus.Such tubing is with nontoxic, light, corrosion-resistant, tube wall is smooth, conveyance capacity
Greatly, speed of application is fast, good seal performance and the advantages that long service life, belongs to environment-friendly and energy-efficient new high-tech product, in city
Political affairs draining, building outdoor drainage, the defeated draining in buried farmland, discharge of industrial wastes, road drainage, sewage treatment plant, sports ground square work
The fields such as journey draining and electrical telecommunication engineering are widely used.
But in the prior art, since the ring stiffness and tensile strength of PVC hollow wound pipe be not high, wearability is bad,
Normal use is unable under the conditions of certain bad environments.
Utility model content
It is not high for PVC hollow wound pipe ring stiffness existing in the prior art and tensile strength, and asking vulnerable to abrasion
Topic, the utility model provide a kind of PVC profile hollow wound pipe.
The technical solution of the utility model are as follows: a kind of PVC profile hollow wound pipe, including two structure bands arranged side by side
Material is connected between two structure bands by melten gel, and successively covers carbon cloth in two structure strip surfaces
And aramid layer, structure band successively include the first cuboid, the second cuboid and third cuboid, structure band from left to right
Three cuboids be hollow structure, be equipped with ribs, ribs in the hollow structure of the first cuboid and third cuboid
It is circular hollow structure at X-shaped structure crossover node for X-shaped structure.
Further, the carbon cloth and aramid layer bonding connection.
Further, the circular hollow diameter at the X-shaped structure crossover node is equal with the reinforcement rib thickness.
The utility model has the beneficial effect that
1. the utility model by the internal structure of improvement structure band, i.e., in the two sides of hollow, rectangular body, setting contains X
The cuboid of shape hollow structure ribs, so that the tubing bearing capacity enhancing after winding, and this X-shaped circular hollow is reinforced
Rib can deal with many different load arrangement variations, so that tubing under external force, is not easy diagonal distortion, thus further
Greatly improve the bearing capacity and ring stiffness of tubing.
It is a kind of intensity 2. carbon cloth has both the strong stretching resistance and the big feature of fiber softening machinability two of carbon material
New material high, density is small, be applicable to the various planforms such as building bridge tunnel reinforcement and repair and seismic hardening and
Carbon cloth is covered on the top of structure band by the structural strengthening of node, reachable using the good tensile strength of carbon cloth
To the purpose of Reinforced PVC profile hollow wound pipe pull resistance and shock resistance.
3. the outer side covering of carbon cloth has aramid layer, polyamide self friction coefficient is small, has good self-lubricating
Property, it can prevent the tube wall of PVC hollow wound pipe from causing tube wall to rupture in use by foreign object frayed, reach raising
The purpose of tubing wearability.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1- structure band, the first cuboid of 2-, the second cuboid of 3-, 4- third cuboid, 5- ribs, 6- are molten
Glue, 7- aramid layer, 8- carbon cloth.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
A kind of PVC profile hollow wound pipe as shown in Figure 1:, including two structure bands 1 arranged side by side, two structures
It is connected between band 1 by melten gel 6, and successively covers carbon cloth 8 and aramid layer 7, structure on two 1 surfaces of structure band
Band 1 successively includes the first cuboid 2, the second cuboid 3 and third cuboid 4, three rectangles of structure band 1 from left to right
Body is hollow structure, and ribs 5 is equipped in the hollow structure of the first cuboid 2 and third cuboid 4, and ribs 5 is X-shaped knot
Structure is circular hollow structure at X-shaped structure crossover node, and the diameter of circular hollow can be equal with the thickness of ribs 5.It is logical
The structure for improving structure band 1 is crossed, i.e., the cuboid containing X-shaped hollow structure ribs 5 is set in the two sides of hollow, rectangular body,
So that the tubing bearing capacity enhancing after winding, and this X-shaped circular hollow ribs 5 can deal with many different loads
Arrangement variation so that tubing under external force, is not easy diagonal distortion, thus further greatly improve tubing bearing capacity and
Ring stiffness.
Person can bond connection between carbon cloth 8 and aramid layer 7, be conducive to connectivity robustness of the layer between layer.
Carbon cloth 8 has both the strong stretching resistance and the big feature of fiber softening machinability two of carbon material, is that a kind of intensity is high, density is small
The structure of new material, the reinforcement and repair and seismic hardening and node that are applicable to the various planforms such as building bridge tunnel adds
Gu carbon cloth 8 to be covered on to the top of structure band 1, using the good tensile strength of carbon cloth 8, Reinforced PVC can reach
The tension of profile hollow wound pipe and the purpose of shock resistance.The outer side covering of carbon cloth 8 has aramid layer 7, and polyamide is certainly
Body coefficient of friction is small, has good self-lubrication, can prevent the tube wall of PVC hollow wound pipe from being ground in use by foreign object
Damage galls, and tube wall is caused to rupture, and achievees the purpose that improve tubing wearability.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
