Abstract

A combined double-wall composite pipe mainly solves such technical problems as complicated manufacturing technology and high manufacturing cost in the prior large diameter plastic tubes. The technical scheme adopts the key points as follows: two or more tegular framework pieces are combined and form an inner framework (1), one or more composite layers (2) are clad on the circumference of the inner framework (1), the section of the inner framework (1) takes a round, square, semi-square semicircular or chamfered square shape, and a reinforced layer (4) can be embedded in the tegular framework pieces of the inner framework (1). Since the inner framework is combined before the composite layer is clad, the manufacturing technology becomes simpler; not only large diameter pipelines made of composite materials can be produced, but such materials as waste plastics can also be utilized for the production; moreover, the manufacturing cost is lower.

Description

A kind of combining double-wall composite pipe
Technical field
The utility model relates to a kind of composite pipe.
Background technique
At present, the production technology more complicated of existing major diameter plastic tube, and cost of production is higher.
Summary of the invention
But the purpose of this utility model provides a kind of production major diameter and the relatively low combining double-wall composite pipe of cost of production.
The technological scheme that its technical problem that solves the utility model adopts is: constitute inner frame 1 by watt shape matrix tablet more than 2 or 2, and be coated with composite bed 2 more than 1 layer or 1 layer in the periphery of inner frame 1.Described inner frame 1 section configuration comprise circle, square, en is semicircle or chamfering is square.Also can be embedded with reinforced layer 4 in watt shape matrix tablet of inner frame 1, described reinforced layer 4 can adopt by latticed or strip material to be made.The outer wall of described inner frame 1 also can connect firmly hollow or solid stiffening rib 3.The section configuration of described stiffening rib 3 comprises circle, circular arc, square or trapezoidal.The distribution mode of described stiffening rib 3 can adopt and comprise helical, circle shape, corrugated or latticed inner frame 1 outer wall that is looped around.Placement between watt shape matrix tablet of described inner frame 1 comprises hot melt, cold cut, snap button or the employing joint socket mode of adopting.Described inner frame 1 comprises with Placement between the clad 2 and adopts hot melt, cold cut or vacuum suction mode to be connected.Described composite bed 2 can adopt macromolecular material or modified alloy material to make, and is wrapped on the outer wall of inner frame 1.
The beneficial effects of the utility model are: it coats composite bed again by making up inner frame earlier, makes production technology simpler.Both can produce large diameter composite material conduit, and can utilize materials such as waste or used plastics to produce, cost of production is relatively low.
