Pipe wall of the pipeline is provided with a metal frame reinforced body covered by plastic and with a shape similar to that of the pipeline. The utility model is characterized in that periphery of the pipe wall is provided with a spiral and hollow reinforced convex tendon. The utility model has high ability of inside and outside bearing of the pressure, and can save a plurality of materials.

Description

Metallic skeleton reinforced composite plastic pipe

The utility model relates to a kind of metal frame and strengthen multiple tube, particularly be the metallic skeleton reinforced composite plastic pipe of the hollow enhancing structure of a kind of tube wall band helical.

The plastic composite pipe that metal frame strengthens is applied in engineering preferably.The metal frame of our indication strengthens pipe or the broadwise steel wire that pipe that body made by the hole pattern sheet metal similar to tube shape of plastic overmold or wire gaze make and twines the pipe that steel radial is made.The plastic composite pipe that this metal frame strengthens has near the interior load performance of metal tube and low linear expansion coeffcient, the excellent antiseptic property that plastic tube is arranged again simultaneously, the plastic tube work is relatively comprehensive with adopting in the engineering, greatly attenuate plastic tube pipe thickness and save lot of materials, because of metal frame bears interior ring stress, be that a kind of engineering is badly in need of, the composite structure composite material of excellent performance, be that a kind of up-and-coming tubing is thinner because of the plastic tube wall that coats, bearing capacity in though the plastic composite pipe that metal frame strengthens has preferably, but it is relatively poor to encircle firm stress ability to bear, has limited the high working environment Application for Field of bearing requirements outside a lot of when particularly caliber is big.In view of above reason, the purpose of this utility model is for the metallic skeleton reinforced composite plastic pipe of the high saving lot of materials of a kind of inside and outside bearing capacity is provided.

The purpose of this utility model is achieved in that

Have in the utility model metallic skeleton reinforced composite plastic pipe tube wall by the metal frame similar of plastic overmold to strengthen body, it is characterized in that the tube wall periphery has the reinforcement convex tendon of the hollow enhancing structure of helical to pipe shape.

Above-mentioned reinforcement convex tendon shaft section is shaped as corrugation type or concave-convex type or circular arc type or cast or square type.

Above-mentioned reinforcement convex tendon adopts the blend of plastics or plastics and mineral filler to make.

Above-mentioned reinforcement convex tendon adopts plastics and metal tube is compound makes.

Above-mentioned reinforcement convex tendon and tube wall are the compound or adhesive bond of fusion.

It is that the sheet metal system that rolls and/or weld forms that above-mentioned metal frame strengthens body.

Above-mentioned metal frame strengthens on the body hole.

It is that the wire gaze system that rolls and/or weld forms that above-mentioned metal frame strengthens body.

It is that broadwise metal strand spiral twines radially the metal strand and/or welding is made that above-mentioned metal frame strengthens body.

Have in the utility model metallic skeleton reinforced composite plastic pipe tube wall by the metal frame similar of plastic overmold and strengthen body to pipe shape, the composite plastic pipe of this structural pipe wall and the plastic tube of equal pipe wall thickness ratio, interior bearing capacity improves greatly, and save a large amount of plastic materialss and reduced the pipeline cost, because of metal frame strengthens the compound of body and plastics, make the linear expansion coeffcient of this pipe be similar to metal tube, overcome the big weakness of plastic lined piping expansion coefficient.Because of the tube wall periphery has the concavo-convex muscle of reinforcement and the tube wall of the hollow enhancing structure of helical compound, not only improved the interior bearing capacity of pipe, more important is because of the hollow-core construction mechanical characteristic, makes the tube wall of thin composite plastic pipe that very high outer bearing capacity arranged.With the known not metallic skeleton reinforced composite plastic pipe comparison of band shape stiffening rib of tube wall, the ring rigidity improves greatly.The metallic skeleton reinforced composite plastic pipe of the spiral helicine hollow enhancing structure of tube wall band, in the processing process, strengthen convex tendon in the shape of a spiral shape with the tube wall fusion is compound or Bond bonds, make production more convenient, with reliable, making the concavo-convex muscle of reinforcement is various different materials and the easier realization of difformity structure of hollow structure continuously.

Embodiment 1:

Fig. 1, Fig. 2 have provided the utility model composite plastic pipe embodiment 1 figure.There is employing hole pattern steel plate to roll the metal frame that is welded in the tube wall 1 that adopts the PVC material to make and strengthens body 2.The hollow enhancing structure of concave-convex type helical is arranged for strengthening convex tendon 3 and being combined into one in the tube wall periphery by Bond 4 and tube wall 1.

Embodiment 2:

Fig. 3, Fig. 4 give by the utility model composite plastic pipe embodiment 2 figure.Useful broadwise steel wire twines the metal frame enhancing body 6 that the steel radial welding is made in the tube wall 5 that the employing polythene material is made.Thermoplastic pipe is spirally wound on the tube wall periphery and has formed the reinforcement convex tendon 7 of the hollow enhancing structure of cast helical and be composited with tube wall 5 fusions.Thermoplastic pipe can adopt polythene material (also can be the blend of polyethylene and mineral filler or the composite pipe of moulding interior steel outward).If adopt outer mould polyethylene with interior be the reinforcement convex tendon that the compound composite pipe of steel pipe forms the hollow enhancing structure of helical, then this composite pipe will have better ring rigidity and interior bearing capacity.

Embodiment 3:

Fig. 5, Fig. 6 have provided embodiment 3 figure of the utility model composite plastic pipe.The metal frame that has wire gaze to roll in the tube wall 8 that pvc material is made to be welded into strengthens body 9.Thermoplasticity square type section bar is spirally wound on the tube wall periphery and has formed the reinforcement convex tendon 10 of the hollow enhancing structure of square type helical and be combined into one with the tube wall fusion.What thermoplasticity square type section bar adopted is pvc material (also can be the blend of PVC and mineral filler, can also be the composite material of steel in outer the moulding).As adopting the reinforcement convex tendon of moulding the composite material spiral winding pipe wall periphery of interior steel outward and forming the hollow enhancing structure of helical, this composite pipe will have very high ring rigidity and interior bearing capacity.

Embodiment 4:

Fig. 7, Fig. 8 have provided the embodiment 4 of the utility model composite plastic pipe.The metal frame that has steel plate to roll in the tube wall 11 that pvc material is made to be welded strengthens body 12, and this enhancing body can have hole, also can not have hole.The reinforcement convex tendon 13 of the hollow enhancing structure of corrugation type (or circular arc type) helical that is composited in the fusion of tube wall periphery.
