Abstract
The invention provides steel-plastic composite strips and steel-plastic composite drainage tubing manufactured by the same. The strip structure consists of a plastic flat strip and a reinforced rib which extends out vertically from the flat strip surface, forms into a whole with the flat strip and is provided with a crimped top end. The reinforced rid is compounded with a reinforced steel strip having two crimped ends. The tubing structure comprises a plastic tube with even wall thickens and a reinforced rib, wherein the reinforced rib is integrated with the tube, is spirally wound on the outer wall of the tube at an equal space, and is in a vertical crimped shape.
Description
Technical field
The present invention relates to a kind of composite steel-plastic belt material, particularly have the composite steel-plastic belt material of special-shaped enhancing steel band and mould composite, water-drain tubing by the steel of its manufacturing.
Technical background
Adopt various forms of plastic straps or section bar, utilize Wrapping formed mode to come production major diameter plastic tube to become known technology, similar products like has hollow wound plastic tube, winding corrugated pipe and riffled tube etc.For the ring stiffness that improves the major diameter wound plastic tube and reduce its cost of production, also occurred adopting metal reinforced plastic band pan in next life to belong to the technology of reinforced plastic tubing in recent years.ZL200520112528.4 discloses a kind of metal reinforced plastic band and by the metal reinforced plastic waste pipe of its manufacturing, as shown in Figure 1 and Figure 2, but there are following defective in this band and tubing:
1. big when pipe diameter, when ring stiffness is higher, the height of band stiffening rib is just higher, stiffening rib lodging shown in Figure 3 very easily appears when band is wound in bending pipes, and the release of the residual stress that the lodging degree produces when can be with band crooked is more and more serious, once this kind situation occurs, the ring stiffness performance of tubing will be difficult to guarantee.
2. owing to metal tape in the stiffening rib is thinner, tubing very easily occurs losing antisepsis because the uneven local pressure conflict excessive or hard thing that lands causes plastics local cracking in stiffening rib top to expose metal tape in storage, transportation, installation process.
In addition, the someone has proposed a kind of
Shape strengthens steel band, but this kind steel band on the one hand its
Two-part can only be by being welded to connect, and increase the complexity of making, on the other hand its
Part face equally because the uneven local pressure conflict excessive or hard thing that lands causes plastics local cracking in stiffening rib top to expose metal tape, lose the problem of antisepsis.
Summary of the invention
One of purpose of the present invention provides a kind of composite steel-plastic belt material that is used for making with the winding form drainage pipe, utilizes this band to make tubing and can make tubing have higher ring stiffness or more save steel and plastics.This band has better structure stability, and in twine making tubing process with it, stiffening rib the phenomenon that lodges can not occur, and can guarantee effectively that tubing has stable structure and reliable ring stiffness performance.
Two of purpose of the present invention provides the steel of the above-mentioned band manufacturing of a kind of usefulness and moulds composite, water-drain tubing, and this tubing manufacture cost is lower, structure and performance are more stable, and the ability that opposing destroys is stronger.
For achieving the above object, the technical solution adopted in the present invention is as follows:
A kind of composite steel-plastic belt material that is used for making in the winding shaping mode drainage pipe, this band are reached by the plastics flat rubber belting with certain width and thickness and extend out from the flat rubber belting Surface Vertical, be integral with flat rubber belting, the summit flanging
The vertical flanging strengthening rib of plastic constitutes, and strengthening rib inside is compounded with the special-shaped steel band that strengthens.
Further, the plastic material of band adopts available extrusion way machine shaping also can implement the thermoplastic of thermal weld to its profiled member; Being compounded with the two ends flanging in the strengthening rib is
Or " the enhancing steel band of [" type;
Or " flanging that [" type strengthens steel band is embedded in the plastics flat rubber belting as the rib pin; Strengthening steel band adopts the steel band of certain width to form through mechanical bending; Determine the quantity of strengthening rib according to the requirement of tubing ring stiffness, two vertical flanging strengthening rib of arranging with equal intervals are arranged on the strip width; Be provided with on the edge of plastics flat rubber belting certain width flanging shape extrude the lapping structure, the direction of its flanging is consistent with strengthening rib top flanging direction.
The present invention also provides a kind of usefulness above-mentioned composite steel-plastic belt material, the steel that twines the method making of overlap joint melting welding by spiral is moulded composite, water-drain tubing, it comprises the plastic tube body of a uniform wall thickness and is integral vertical flanging strengthening rib at the equidistant spiral surrounding of tube wall with body that the inwall of body is a continuous formation.
Further, be to adopt overlap joint and in overlapping the slot, clamp-on the melting Plastic Welding identical between the composite steel-plastic belt material of formation tubing with the body material.
In technique scheme, strengthen steel band and take
Or " [" structure, under the sectional area same case, in the comparable existing known technology " Shu " and
The moment of inertia that the type structure strengthens steel band is bigger, can make the ring stiffness of tubing higher, and when moment of inertia identical (the tubing ring stiffness is identical), sectional area can be littler and the tubing cost of production is reduced.
Or " lower hem in [" structure is embedded in band plastics flat rubber belting or the body as the rib pin, can increase the fixedly supporting role of plastics to steel band, solve in the BENDING PROCESS that the composite steel-plastic belt material is wound in tubing the easily problem of lodging of strengthening rib effectively, improved the structure stability of tubing.
Or " upper hem in [" structure has increased tubing at the area that lands of storing, transporting, bury underground in the process, has reduced pressure, and it is destroyed that the tube surfaces plastic layer is difficult for.
