Description
Technical field
The utility model belongs to polyethylene material pipeline configuration field, is related to a kind of strip enhancing bellows, more particularly to
A kind of symmetric trapezium structure steel strip reinforced bellows.
Background technology
The bellows of polyethylene material, i.e. the plastic protective sleeve pipe of 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 higher cast device of frequency of use 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 there have been a kind of reinforced steel-band polytene corrugated tubes in the market, 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 using lower bellows segment for a long time, and tube body is easily rupturable, 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 symmetric trapezium structure steel strip reinforced bellowss.The ring for effectively raising tube body is rigid
Degree, extends the service life of bellows.
The technical solution of the utility model is：A kind of symmetric trapezium structure steel strip reinforced bellows, including steel belt layer
And bellows band；Above-mentioned steel belt layer passes through ring-wound formed inner tube；Said inner tube is hollow cylinder；Above-mentioned bellows band is in
Spiral wound forms the equal changeover portion of several spacing on steel belt layer；It is characterized in that：Above-mentioned steel belt layer includes
Matrix and reinforcing prop in matrix surface centre position is set；Above-mentioned bellows band cross section is in symmetric trapezium structure；It is above-mentioned right
Trapezium structure is claimed to be spliced by two class isosceles trapezoids.
The seam spiral winding formed when above-mentioned bellows band is along steel belt layer ring-wound.
Ratio of the above-mentioned bellows with symmetric trapezium structure height and transition width is 1:1-3.
Ratio of the above-mentioned bellows with symmetric trapezium structure height and transition width is 1:2.
It is 1 that above-mentioned reinforcing prop height of projection compares with bellows band symmetric trapezium structure height:5-9.
It is 1 that above-mentioned reinforcing prop height of projection compares with bellows band symmetric trapezium structure height:7.
It is high that above-mentioned matrix cross sections height is less than bellows band symmetric trapezium structure.
The utility model has the advantages that：
First, the hexagon steel strip reinforced bellows that the utility model is proposed is by changing knot of the bellows with cross section
Structure makes bellows band itself improves bearing capacity, from the whole ring stiffness for improving bellows, extends the use of bellows
Service life.
Secondly, the hexagon steel strip reinforced bellows that the utility model is proposed by steel band itself increase reinforcing prop from
And the integral strength of bellows is improved, in the case of identical material, manufacturer can utilize identical material to make more
Bigbore bellows enhances the market competitiveness of bellows.

Specific implementation mode
In order to make technical solutions of the utility model be 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 symmetric trapezium structure steel strip reinforced bellowss, including steel belt layer 6 and bellows band
2；Steel belt layer 6 passes through ring-wound formed inner tube；Inner tube is hollow cylinder；Bellows band 2 is spirally wrapped around steel belt layer 6
On, and form the equal changeover portion 1 of several spacing；Steel belt layer 6 is including matrix 3 and adding in 3 surface centre position of matrix is arranged
Strong column 4；2 cross section of bellows band is in symmetric trapezium structure 5；Symmetric trapezium structure is spliced by two class isosceles trapezoids..
The seam spiral winding formed when bellows band 2 is along 6 ring-wound of steel belt layer.
Reinforcing prop 4 be located at bellows band 2 it is helically wound when the changeover portion 1 that is formed on.
Ratio of the bellows with 5 height of symmetric trapezium structure and 1 width of changeover portion is 1:1-3.
