Abstract
The utility model relates to a round-pipe framework externally-combined-type large-diameter corrugated pipe, effectively allowing not only an increase in the strength of large-diameter corrugated pipes, but also fundamental improvement in the elasticity of large-diameter corrugated pipes. The round-pipe framework externally-combined-type large-diameter corrugated pipe comprises an inner pipe. The outer wall surface of a round pipe spirally wound on the inner pipe body has a convex-concave structure. Plastic layers are combined on the outer wall of the round pipe and are in uneven non-pure-planar combination with the outer wall. The round-pipe framework externally-combined-type large-diameter corrugated pipe has the advantages that firstly, the round metal pipe, with good pressure resisting and dispersing ability, not only achieves high pressure-bearing capacity and pressure resistance, but also greatly enhances the supporting strength and the pressure-bearing capacity of the inner pipe; and secondly, the surface of the round pipe has a concave-convex structure as if the plastic layers are provided with plastic wedges, and wedged and embedded combination of the plastic layers and the round pipe wall is formed, with high combination strength, avoiding the layering phenomenon.
Description
Technical field
The utility model relates to a kind ofly can not only improve heavy caliber bellows intensity effectively, and can make the elasticity of heavy caliber bellows obtain the outer compound heavy caliber bellows of a kind of circular pipe frame that essence improves, and belongs to bellows and makes the field.
Background technique
CN201078525Y, title " socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe ", it is used to solve the problem of easy seepage of steel band reinforced polyethylene spiral ripple pipe connection interface and poor reliability.Socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe; Be the metal frame that twines to be fixed on the inner layer polyethylene with outer layer polyethylene; Particularly an end of bellows is provided with socket, and the other end of bellows is provided with bellmouth, imbeds a circle electric heating element on the bellmouth inwall and forms.Adopt this socket joint electric smelting jointing type steel band reinforced polyethylene spiral ripple pipe, can be widely used in the connection construction of plastic tube.Its deficiency: the one, metal frame is the outer structure of taking off, and what form with inner layer polyethylene is that the line face contact, rather than face contacts; Not only plyability is poor; And under the effect of external force, metal frame is prone to take off mobile outward, causes inner layer polyethylene is destroyed; The quality of direct shadow pipe matter, even cause inner layer polyethylene damaged; The 2nd, support strength is low, because metal frame is the outer structure of taking off, outwards move its metal frame both sides of external pressure, not only causes the layering of metal frame and inner layer polyethylene, and cause the direct reduction of inner layer polyethylene intensity; The 3rd, because outer layer polyethylene and metal frame are two kinds of material different, had nothing in common with each other by its coefficient that expands with heat and contract with cold of Influence of Temperature, therefore stratification in use takes place inevitably, cause bellows intensity sharply to descend, bellows caves in.
The model utility content
Purpose of design: avoid the deficiency in the background technique, design and a kind ofly can not only improve heavy caliber bellows intensity effectively, and can make the elasticity of heavy caliber bellows obtain the outer compound heavy caliber bellows of a kind of circular pipe frame that essence improves.
Design proposal: in order to realize above-mentioned purpose of design.Circular tube external wall face concave-convex surface structure Design in being spirally wound on the pipe pipe shaft is the major technique characteristic of the utility model.The purpose of doing like this is: the convexity in the concavo-convex structure of the wall of pipe and recessed; Just as stiffening rib, both improved the intensity of pipe wall, make the bonding more cementation of molten plastic and pipe wall again; The more important thing is these male and fomale(M&F)s; Mutual restriction coefficient of dilatation during temperature variation, make its temperature variation that more is adapted to plastic layer, thereby avoided the appearance of stratification effectively.
Technological scheme: the outer compound heavy caliber bellows of a kind of circular pipe frame, it comprises interior pipe, the inside and outside wall concave-convex surface structure of the pipe in being spirally wound on the pipe pipe shaft, plastic layer is compounded on the circular tube external wall and is rough non-pure flat with outer wall and combines.
The utility model is compared with background technique, and the one, metal circular tube has good resistance to compression dispersibility, and not only bearing capacity is big, resistance to compression, and has greatly improved the support strength and the bearing capacity of interior pipe; The 2nd, the pipe face is a concaveconvex structure, just just as plastic layer the plastics wedge has been arranged, formation be that the wedge embedding is compound between plastic layer and pipe wall, combined strength bination is high, stratification can not take place.
Description of drawings
Fig. 1 is the structural representation of the outer compound heavy caliber bellows of circular pipe frame.
Fig. 2 is the cross section structure schematic representation of the multiple plastic layer of circular tube external wall among Fig. 1.
Embodiment
Embodiment 1: with reference to accompanying drawing 1-2.The outer compound heavy caliber bellows of a kind of circular pipe frame, pipe 1 in it comprises, the pipe 2 outer wall concave-convex surface structures in being spirally wound on pipe 1 pipe shaft, plastic layer 3 is compounded on pipe 2 outer walls and is rough non-pure flat with outer wall and combines.The face of pipe 2 outer walls of said concavo-convex structure is non-pure flat, and purpose improves bonding force between the two.Its making method: with the concavo-convex mould in the logical roll unit of non-pure flat steel band; Be squeezed into male and fomale(M&F); So the steel band of male and fomale(M&F) is rolled into pipe through rolling machine; After the pipe surface carried out cleaning and handle; Adopt the heavy caliber polyolefin of claimant's manufacturing to twine to increase the pipe production line in making bellows in the pipe process, the pipe that make pipe in the bellows on one side, inside and outside wall is male and fomale(M&F) is wrapped on the bellows and adopts the heavy caliber polyolefin of claimant's manufacturing to twine growth and manage production line molten plastic is compounded on the pipe wall of male and fomale(M&F).Molten plastic is compounded on the outer wall of pipe of male and fomale(M&F).
What need understand is: the detailed text description though above-mentioned mentality of designing to the utility model is contrasted; But these text descriptions; Just the simple text of the utility model mentality of designing is described, rather than, appointed Ke to be no more than the combination of the utility model mentality of designing the restriction of the utility model mentality of designing; Increase and modification, all fall in the protection domain of the utility model.
Claims (2)
1. the outer compound heavy caliber bellows of a circular pipe frame, it comprises interior pipe, it is characterized in that: the inside and outside wall concave-convex surface structure of the pipe in being spirally wound on the pipe pipe shaft, plastic layer is compounded on the circular tube external wall and is rough non-pure flat with outer wall and combines.
