Description
Technical field
The utility model belongs to polyethylene material pipeline configuration field, be related to a kind of strip enhancing bellows more particularly to
A kind of M steel band of model enhances bellows.
Background technology
The plastic protective sleeve pipe of the bellows of polyethylene material, i.e. polyethylene material extrusion molding, because its inside and outside is ring
Shape corrugated is called bellows.It is without damage that object in protection pipe can be played.Wearability is good, it is corrosion-resistant the features such as.
Bellows is the cast device that frequency of use is higher in present industrial society, and in order to adapt to different construction environments
And different usages, user is to the rigidity of bellows, intensity and corrosion-resistant, wear-resistant suffers from higher requirement.
Then in the market there have been a kind of reinforced steel-band polytene corrugated tube, due to reinforced steel-band polyethylene helical
Bellows has the characteristics that high rigidity, high intensity and corrosion-resistant, wear-resistant and flexibility are strong, therefore, reinforced steel-band polyethylene
Bellows is widely used.But the tubing mechanical strength for the reinforced steel-band polyethylene helical bellows being commonly used is not
Good, ring stiffness is relatively low, and since bellows can be embedded in underground when in use, soil focuses mostly in wave to the active force of bellows
Peak peak is deformed upon, and tube body is easily rupturable for a long time using lower bellows segment, and service life is shorter.
Utility model content
In order to which the existing corrugated pipe ring rigidity for solving to be previously mentioned in background technology is low, tube body is easily rupturable, service life is shorter
The problem of, the utility model proposes a kind of M steel band of model to enhance bellows.The ring stiffness of tube body is effectively raised, is extended
The service life of bellows.
The technical solution of the utility model is：A kind of M steel band of model enhances bellows, including steel belt layer and bellows
Band；Above-mentioned steel belt layer passes through ring-wound formed inner tube；Above-mentioned inner tube is hollow cylinder；Above-mentioned bellows band twines in the shape of a spiral
It is wound on steel belt layer, and forms the equal changeover portion of several spacing；It is characterized in that：Above-mentioned steel belt layer includes matrix and sets
Put the reinforcing prop in matrix surface centre position；Above-mentioned bellows band cross section forms two bellows band wave crests in M types.
The seam spiral winding formed when above-mentioned bellows band is along steel belt layer ring-wound.
On the changeover portion formed when helically wound positioned at bellows band of above-mentioned reinforcing prop.
Ratio of the above-mentioned bellows with the distance between wave crest top to steel belt layer and transition width is 1:1-3.
Ratio of the above-mentioned bellows with the distance between wave crest top to steel belt layer and transition width is 1:2.
Above-mentioned reinforcing prop height of projection is with bellows band wave crest top to steel belt layer distance than being 1:5-9.
Above-mentioned reinforcing prop height of projection is with bellows band wave crest top to steel belt layer distance than being 1:7.
Above-mentioned matrix cross sections height is less than bellows with wave crest top to the height between steel belt layer.
The utility model has the advantages that：
First, the M steel band of model that the utility model is proposed enhances bellows by changing structure of the bellows with cross section,
Bellows band is made to itself improves bearing capacity, from the whole ring stiffness for improving bellows, extend bellows uses the longevity
Life.
Secondly, M steel band of model that the utility model is proposed enhancing bellows by steel band is increased in itself reinforcing prop so as to
The integral strength of bellows is improved, in the case of identical material, manufacturer can utilize identical material to make bigger
The bellows of bore enhances the market competitiveness of bellows.

Specific embodiment
In order to which technical solutions of the utility model are more clearly understood, below in conjunction with attached drawing 1-2 and embodiment, to this practicality
It is novel to be further elaborated, so that those skilled in the art can be better understood from and implement, it is not used to limit
The utility model.
The utility model proposes a kind of M steel band of model to enhance bellows, including steel belt layer 6 and bellows band 5；Steel belt layer 6
Pass through ring-wound formed inner tube；Inner tube is hollow cylinder；Bellows band 2 is spirally wrapped around on steel belt layer 6, and is formed
The equal changeover portion 1 of several spacing；Steel belt layer 6 includes matrix 3 and the reinforcing prop 4 for being arranged on 3 surface centre position of matrix；Ripple
2 cross section of pipe band is in M types, and forms two bellows band wave crests 5.
