Description
Technical field
This utility model belongs to tubing technical field, and more particularly to a kind of internal-rib strengthens polyethylene helical bellows.
Background technology
At present, polyethylene helical bellows are widely used in municipal blowdown because it has good pipeclay collective effect
During pipeline engineering is built.
Existing polyethylene helical bellows are usually to be formed by multiple banding sheet materials winding bonding, and its bearing area is little, makes
Not enough into bearing capacity, ring stiffness is little, directly affects the performance of product.
Therefore, how to solve the defect of above-mentioned prior art presence becomes the direction of art personnel effort.
Utility model content
The purpose of this utility model is just to provide a kind of internal-rib strengthens polyethylene helical bellows, can be fully solved above-mentioned existing
There is the weak point of technology.
The purpose of this utility model is realized by following technical proposals：
A kind of internal-rib strengthens polyethylene helical bellows, including by banding sheet material spiral winding and the pipe that is mutually bonded
Body, it is characterised in that：The banding sheet material includes substrate, left plate, right plate, left riser and right riser, the substrate both sides
Edge is symmetrical arranged left plate and right plate, and left and right side plate is vertical with substrate, be correspondingly arranged between left and right side plate a left side,
Right riser, and the angle of left and right riser and substrate is more than 90 °, the height of left and right riser less than left and right side plate height, it is left,
The top of right riser is connected with the top of corresponding left and right side plate by circular arc rebound, left and right side plate, left and right riser,
Circular arc rebound and substrate surround two symmetrical hollow cavities, and ribs is provided with hollow cavity.
Preferably, the ribs is plastic plate.
Preferably, the ribs is n shape structures.
Preferably, the ribs is z shape structures.
Preferably, the ribs is x shape structures.
Preferably, the ribs is flat board, its one end correspondence is fixed on left and right riser top inner side, the other end pair
Left and right side plate inner side should be fixed on, ribs correspondence surrounds two symmetrically with left and right riser, left side plate and circular arc rebound
Sector.
Compared with prior art, the beneficial effects of the utility model are：Simple structure, it is reasonable in design, by left and right side
Plate is vertical with substrate, and using the angle between left and right riser and substrate 90 ° are more than, and fit circular arc shape rebound correspondence connects
Left and right side plate and left and right riser so that corrugated tube pressure-bearing surface connects increase, so as to lift the bearing capacity and ring stiffness of corrugated tube；
And ribs is provided with hollow cavity, the ring stiffness of corrugated tube can be further lifted.
