Description
Technical field
The present utility model relates to a kind of hollow steel strip reinforced winding bellows built for municipal drain and blow-off line in pipeline material field.
Background technique
In urban construction, subsoil drain and burying underground of drain pipe are important municipal engineering, conventional waste pipe and drain pipe have concrete pipe and metal tube, it is strong that new material high-strength polyethylene has pliability, corrosion resistant and wear-resisting performance, compare same diameter can reduce costs significantly with the all-plastic buried drain pipe of ring stiffness, reaching high performance while, its outstanding advantage saves material, the outer ripple plastic winding structure wall pipe with hollow reinforced rib is widely used in during municipal blow-off line builds owing to having good pipeclay acting in conjunction and ring stiffness.The winding bellows device of all-plastic is relatively simple, but to being greater than the tubing of 1000 millimeters, reach its plastic layer of ring stiffness requirement and will become very thick, tubing cost will improve.Therefore, be necessary to provide a kind of Novel belt material with the outer ripple plastic winding structure wall pipe of hollow reinforced rib, to overcome the defect on said structure.
Summary of the invention
The purpose of the present utility model is that the defect of the winding bellows overcoming existing all-plastic provides a kind of Novel hollow steel strip reinforced to be wound around bellows.
The present utility model is achieved through the following technical solutions:
A kind of hollow steel strip reinforced is wound around bellows, by the tubing of the enhancing band spiral winding welding with steel band, it is characterized in that: described enhancing band is provided with hollow boss stiffening rib, the cross section semicircular in shape structure of hollow boss, with steel band in hollow boss stiffening rib, strengthen band, by extruder, HDPE high density polyethylene (HDPE) or FRPP polypropylene and steel band are mixed and made into semi-finished product, Stetch Wrapping Machine is wound around in a spiral manner strengthening band and fuses into tubing body in lap-joint through melten gel, tubing inner body wall is cylindrical wall, tubing body outer wall is spiral surrounding hollow boss stiffening rib thereon, hollow reinforced rib is perpendicular to tube wall, the hollow reinforced rib of described enhancing band is made up of the hollow cavity of two opposed, side-by-side, steel band is had between two hollow cavities, strengthen the junction plane that there is symmetrical fusion molding band both sides, Novel hollow reinforcing rib structure with steel band improves ring stiffness and the intensity of tubing, described enhancing band PE material used is for HDPE high density polyethylene (HDPE) or FRPP polypropylene material.
The utility model has following beneficial effect:
1. novel hollow reinforced rib structure has good ring stiffness and higher intensity.
2. face of weld heat seal strength is high.
Accompanying drawing explanation
Fig. 1 is that hollow steel strip reinforced is wound around bellows outline drawing;
Fig. 2 is the enhancing band sectional view with steel band.
In figure: heterotypic strip body 1, structural cavities 2, amplexiform face 3 and steel band 4.
Embodiment
Below in conjunction with accompanying drawing, content of the present utility model is described further:
As shown be hollow steel strip reinforced and be wound around bellows outline drawing and band sectional view, by heterotypic strip body 1, heterotypic strip body 1, structural cavities 2, amplexiform face 3 and steel band 4 forms, strengthen band strong by pliability, the HDPE high density polyethylene (HDPE) of corrosion resistant and wear-resisting property or FRPP polypropylene material and steel band are made, first by extruder squeeze out HDPE or FRPP material and steel band be mixed semi-finished product enhancing band, strengthen band and be provided with hollow reinforced rib, hollow reinforced rib is made up of the hollow cavity of two opposed, side-by-side, steel band is had between two hollow cavities, strengthen the junction plane that there is symmetrical fusion molding band both sides, strengthen band and on special production line, be wound in tubing body by Stetch Wrapping Machine in a spiral manner, the face of weld of heterotypic strip is by the melting adhered one-tenth body of colloidal sol, tubing inner body wall is cylindrical wall, tubing body outer wall is spiral surrounding hollow reinforced rib thereon, hollow reinforced rib is perpendicular to tube wall, hollow reinforced rib improves ring stiffness and intensity.
Claims (2)
1. a hollow steel strip reinforced is wound around bellows, by the tubing of the enhancing band spiral winding welding with steel band, it is characterized in that: described enhancing band is provided with hollow boss stiffening rib, the cross section semicircular in shape structure of hollow boss, with steel band in hollow boss stiffening rib, strengthen band, by extruder, HDPE high density polyethylene (HDPE) or FRPP polypropylene and steel band are mixed and made into semi-finished product, Stetch Wrapping Machine is wound around in a spiral manner strengthening band and fuses into tubing body in lap-joint through melten gel, tubing inner body wall is cylindrical wall, tubing body outer wall is spiral surrounding hollow boss stiffening rib thereon, hollow reinforced rib is perpendicular to tube wall, the hollow reinforced rib of described enhancing band is made up of the hollow cavity of two opposed, side-by-side, steel band is had between two hollow cavities, strengthen the junction plane that there is symmetrical fusion molding band both sides.
2. hollow steel strip reinforced according to claim 1 is wound around bellows, it is characterized in that: described enhancing band raw material used is HDPE high density polyethylene (HDPE) or FRPP polypropylene and strip material.
