Abstract
The utility model discloses a kind of high-strength airduct of novel wound dragging and squeezing glass fiber reinforced plastics, it is outer in include base tube, FRP sleeve pipes, FRP windings enhancement layer, superficial layer respectively, base tube is made up of flame-retarded resin, the 3mm of the thickness of pipe 2, it is in wavy bumps on its internal face, aluminium-hydroxide powder is added with flame-retarded resin；FRP sleeve pipes, by disk of weaving, infiltrate resin by glass fibre after working out packaged tube.The utility model is simple in construction, reasonable in design, by double wave structures of dislocation, realizes the reinforcement of axial structural strength, and ensure the structural strength of radial direction using FRP sleeve pipes.
Description
Technical field
A kind of airduct is the utility model is related to, specifically a kind of lightweight and the high novel wound pultrusion glass of structural strength
The high-strength airduct of steel.
Background technology
Mine, underground ventilation mainly use seamless steel pipe at present, and greatest problem is exactly pipe corrosion.Steel pipe is too heavy, support
Complicated, input is big.FRP pipes are applied to the field with the good characteristic such as its high-strength light, corrosion-resistant, resistance to compression at present.But mesh
Preceding market FRP pipe greatest problems, be exactly wall thickness, cost is high；Poor flame retardant properties.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of present in prior art, there is provided a kind of novel wound of lightweight is drawn
Squeeze the high-strength airduct of fiberglass.
To achieve the above object, technical scheme used by the utility model：A kind of novel wound dragging and squeezing glass fiber reinforced plastics are high-strength
Airduct, outer in include base tube, FRP sleeve pipes, FRP windings enhancement layer, superficial layer respectively, base tube is made up of flame-retarded resin, managed
Thick 2-3mm, it is in wavy bumps on its internal face, aluminium-hydroxide powder is added with flame-retarded resin；FRP sleeve pipes are by glass
Fiber, by disk of weaving, infiltrate resin after working out packaged tube；FRP sleeve pipes are tightly placed in outside base tube, and are connected with base tube by glue
It is integrated, the thickness of pipe 2-3mm of FRP sleeve pipes；Thickness 2-3mm is strengthened in FRP windings, and FRP sets are circumferentially wrapped in by glass fabric
Outer, its winding density circulation change is managed, makes undulate on FRP winding enhancement layers concavo-convex, and in its waveform bumps and base tube
Wavy concavo-convex position on wall is staggered；Superficial layer is used to fill and lead up FRP winding reinforcement layer surfaces, and superficial layer is by flame-retarded resin
It is made, thick 1.5-2.5mm, ultra-violet absorber is mixed with flame-retarded resin.
The utility model is simple in construction, reasonable in design, by double wave structures of dislocation, realizes axial structural strength
Strengthen, and ensure the structural strength of radial direction using FRP sleeve pipes.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further understood from for convenience, embodiment is enumerated in conjunction with accompanying drawing, the utility model is made
Further instruction.
Embodiment：
As shown in figure 1, the utility model to it is interior and it is outer respectively include base tube 1, FRP sleeve pipes 2, FRP winding enhancement layer 3, table
Surface layer 4, base tube 1 are made up of flame-retarded resin, thickness of pipe 2mm, are in wavy bumps on its internal face, are added with flame-retarded resin
Aluminium-hydroxide powder；FRP sleeve pipes 2, by disk of weaving, infiltrate resin by glass fibre after working out packaged tube；The tight set of FRP sleeve pipes 2
It is fixed with one outside base tube 1, and with base tube 1 by glue, the thickness of pipe 2mm of FRP sleeve pipes 2；FRP winds 3 thick 2mm of enhancement layer,
Circumferentially it is wrapped in outside FRP sleeve pipes 2 by glass fabric, its winding density circulation change, it is in ripple to make on FRP winding enhancement layers 3
Shape wave is concavo-convex, and its waveform bumps are staggered with the wavy concavo-convex position on the internal face of base tube 1；Superficial layer 4 is used to twine FRP
Filled and led up around the surface of enhancement layer 3, superficial layer 4 is made up of flame-retarded resin, thick 1.5mm, and ultra-violet absorber is mixed with flame-retarded resin.
It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal
Limitation, any person skilled in the art is changed or is modified to possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change, but it is all without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model
Any simple modification, equivalent change and modification made to above example, still fall within the model of technical solutions of the utility model
In enclosing.
