Description
Technical field
The utility model relates to drainage, is specifically related to a kind of steel strip reinforced screw thread bellows.
Background technique
Steel band reinforced spiral ripple pipe has the features such as high rigidity, high strength and corrosion-resistant, wear-resistant and pliability be strong; Therefore, its steel-plastic composite pipe as a kind of high performance-price ratio is widely used in the fields such as draining such as municipal administration, industry, agricultural and traffic engineering construction.Common steel band reinforced spiral ripple comprises inner tube, external pipe and steel band, and it is overall that pipe makes firmly steel strip reinforced screw thread corrugated tube by inner tube forming process, the compressing process of steel band, the bending winding of steel band and process and external pipe compound molding process.
The patent No. is " CN 103727325 A ", application number is " 201310731478.7 ", name is called a kind of steel strip reinforced screw thread of the disclosure of the invention of " High-performance low-cost " bellows, as shown in Figure 1, 2, comprise inner tube, the V-shaped cross section steel band that inner tube external spiral shape winding steel is pressed into, at interior tube layer and the outer composite skins pipe of V-shaped steel band.Because V-shaped steel band is chimeric with external pipe by compacting, therefore steel band both sides of the edge are pressed in external pipe, and when bellows is under pressure, bellows occurs to bear pressure by deformation, the compressive strength of bellows is not high enough, and steel strip surface is also fitted with outer layer surface.When reclaiming the steel band in steel band reinforced spiral ripple pipe, stripping steel band and external pipe have certain difficulty, and affect effective recovery of steel band and plastics, its intensity is also subject to certain impact.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can strengthen compressive strength, rigidity and enhancing helical bellows moulded by the steel being beneficial to recycling plastics and steel band.
For reaching above object, the utility model provides a kind of steel to mould enhancing composite helical bellows, comprises clad, bottom body and steel band, and steel band is between clad and bottom body, and described steel band mainboard both sides of the edge outwards bend, and forms flange; Cavity is formed in clad and steel strip surface.Bottom tube surfaces has the support bracket of coiled coil, and flange is against support bracket; Clad is wrapped on outside support bracket and steel band.When steel band is under pressure, support bracket effectively can share the stress of steel band both sides, adds rigidity and the compressive strength of threaded pipe entirety.Change the shape of steel band, when steel band is stressed, reduce deformation, rely on support bracket to share pressure, increase bellows strength and stiffness.Isolate clad along cavity when reclaiming simultaneously, can light strip off clad, obtain complete steel band and plastic pipe, be beneficial to recovery.
Support bracket can be the supporting part that mechanical field is conventional, and preferred support bracket is by two axisymmetric and forming to the support angle of lateral bend on cross section.
Preferably, described flange and mainboard form acute angle.To guarantee that between flange and bellows, cavity is unsuitable excessive.
Preferably, steel band main body section is arch.Steel band top still with clad laminating, not only increase frictional force and stablize steel band and not easily slide and increase the rigidity of bellows simultaneously.
Steel of the present utility model is moulded enhancing composite helical bellows and is added support bracket, effectively shares stress, enhance the strength and stiffness of steel band when steel band is stressed in both sides.Change the sectional shape of steel band further, steel band edge is outwards bent and is fixed against support bracket by flange, make clad and steel strip surface form cavity, decrease steel band deformation, be conducive to the stressed of support bracket and share.Steel band conveniently can be taken out the recovery also facilitating sebific duct by the clad when reclaiming bellows by isolating the top layer of cavity.
The beneficial effects of the utility model are, add rigidity and the compressive strength of composite helical bellows, and mould steel and strengthen that the steel band of composite helical bellows and the separation and recovery of parts of plastics become simply, facilitate, loss is few, are beneficial to resource reutilization.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Embodiment 1:
A kind of steel according to Fig. 3,4 is moulded and is strengthened compound (PE-M) helical bellows, and comprise clad 1, bottom body 2 and steel band 3, the material of clad 1 and bottom body 2 is PE-M blending resin.Bottom body 2 is pressed into tubulose, its outer surface has support bracket 21, and support bracket 21 spiral winding is on bottom body 2.Support bracket 21 is made up of two support angles, on cross section, and two support angle specular, and to lateral bend.Bottom body 2 is wound around bending steel band 3, steel band 3 mainboard 31 overarches, and mainboard 31 both sides of the edge are outwards bent to form flange 32, flange 32 against the support bracket 21 of both sides, by frictional force fixing internal steel band.At steel band 3 and support bracket 21 surface compacting clad 1.Clad 1 and steel band 3 surface form cavity 4 in side.
Embodiment 2:
A kind of steel is moulded and is strengthened compound (PE-M) helical bellows, and when bellows is under pressure, included steel band flange 32 is stressed to both sides, and the support bracket 21 on bottom body 2 shares the stress of steel band 3, strengthens integral rigidity and the intensity of bellows.When bellows is discarded be in recovery state time, the cavity 4 along steel band in bellows 3 both sides cuts clad 1, after strip off clad 1, directly can take out steel band, be beneficial to the recovery of steel band and plastics, be beneficial to resource reutilization.
Below the embodiment that is preferably that the utility model is created is illustrated, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to the utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
