Abstract
The utility model relates to a fiber glass reinforced plastics ventilating pipeline which is assembled by composite air duct plates. The utility model is characterized in that the center layer of each composite air duct plate is provided with an inorganic foam board 2; both faces of each composite air duct plate is stuck with an inorganic fiber glass reinforced plastics thin plate 3 by using an inorganic bond 4; the outside surface of each composite air duct plate is coated with a corrosion prevention and fireproof modified phenolic resin layer 5. Thus the composite air duct plate 1 is formed. At the time of assembly, the composite air duct plates are supported, inserted and stuck by using inorganic fiber glass reinforced plastics section material connecting strips 6 whose outside can be coated with the corrosion prevention and fireproof modified phenolic resin layers 5 for manufacture of the fiber glass reinforced plastics ventilating pipeline. The utility model has the advantages of light weight, high intensity, fire prevention, corrosion prevention, ageing resistance, easy transportation, etc., and has originality because the assembling mode of using inorganic fiber glass reinforced plastics section material connecting strips.
Description
The utility model relates to the ventilation equipment field, particularly a kind of glass fibre reinforced plastics ventilation pipeline.
Existing perspex steel ventilation shaft matrix material is a synthetic resin, and anti-corrosive properties are fine, but fire prevention does not pass a test; The inorganic glass fibre reinforced plastics ventilation pipeline matrix material is a magnesia oxychloride cement, and fire line is fine, but anticorrosion, ageing-resistant poor performance.The pipeline of above two kinds of which kind of matrix materials no matter must be by increasing duct wall thickness or making the problem that reinforcement solves the stiffness deficiency for bigbore pipeline, and this certainly will increase weight, increases cost.In addition, because this kind moulding conduit volume is big, the loading and unloading difficulty, transportation inconvenience has also increased cost of transportation.
But the purpose of this utility model provides a kind of anticorrosion, fire prevention, ageing-resistant, light weight, high-strength, easy transportation assembled in situ, new glass fibre reinforced plastic ventilation shaft that cost is low.
Adopt compound air duct plate scene to assemble for reaching above-mentioned purpose the utility model.Compound air duct plate central core is inorganic foamed plate, the unorganic glass steel sheet is pasted with inorganic bond in the cystosepiment two sides, outermost layer is coated anticorrosion, fireproof phenol-formaldehyde resin modified layer, according to the thickness of compound air duct plate, the unorganic glass steel profile that compacting matches in mould is connected bar.The combination cross section of rectangle ventilation duct guidance tape is
The unorganic glass steel profile of type is connected bar, and the combination cross section of circular ventilation duct guidance tape is that the unorganic glass steel profile of " H " type is connected bar.Be connected the bar appearance in the unorganic glass steel profile and coat anticorrosion, fireproof phenol-formaldehyde resin modified layer.During assembling, the compound air duct plate bonds together by unorganic glass steel profile linking bar socket joint and surrounds glass fibre reinforced plastics ventilation pipeline.
Adopt above technical scheme, can reduce ventilation shaft weight greatly, reduce cost, make ventilation shaft have light weight, high-strength characteristics, have good fire prevention, anticorrosion, ageing-resistant performance simultaneously.This kind frame mode can be taked on-the-spot assembling, the loading and unloading convenient transportation, and it is little to take up room, and can reduce cost of transportation greatly.In addition, it is simple to use the unorganic glass steel profile to be connected the bar assembling, has solved the problem of other bonding way undercapacity preferably.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is for figure cuts open in the horizontal office of first embodiment of the utility model.
Fig. 2 is for figure cuts open in the horizontal office of second embodiment of the utility model.
Among Fig. 1, add blowing agent with magnesia oxychloride cement and in mould, make board-like inorganic foamed plate 2, after solidifying drying, earlier at one side brushing inorganic bond 4, unorganic glass steel sheet 3 is put compacting, cemented, then cystosepiment 2 another sides are coated inorganic bond 4, stick 3 compactings of unorganic glass steel sheet, cement.At last the sheet material two sides is coated with fire prevention, corrosion-resistant phenol-formaldehyde resin modified layer 5 respectively, makes compound air duct plate 1 after the curing.Thickness, compacting cross section according to compound air duct plate 1 are
The unorganic glass steel profile of shape enables to be inserted in the compound air duct plate 1.That the section bar appearance that is pressed into is coated with is anticorrosion, fireproof phenol-formaldehyde resin modified layer 5 is made the unorganic glass steel profile and is connected bar 6.Compound air duct road 1 is cut into design size, the unorganic glass steel profile is connected bar 6 is cut into isometricly with it, at last compound air duct plate 1 usefulness unorganic glass steel profile linking bar 6 socket joints are bonded together, surround air channel 7, make glass fibre reinforced plastics ventilation pipeline.
In the accompanying drawing 2, compound air duct plate 1 cross section is semicircle.During the inorganic foamed plate 2 of processing and fabricating, mould will be made half-circle-arc shape.Stir well adding blowing agent in the modified magnesium oxychloride cement earlier, pour in the mould, make inorganic foamed plate 2 after the curing.To cement on its two sides according to the unorganic glass steel sheet 3 usefulness inorganic bonds 4 that the respective shapes size makes then, be coated with anticorrosion, fireproof phenol-formaldehyde resin modified layer 5 more respectively on the two sides.Having made cross section after the curing drying is semicircular compound air duct plate 1.Make another symmetrical compound air duct plate 1 on can complying with.Thickness according to compound air duct plate 1 pastes the unorganic glass steel profile linking bar 6 of cross section for " H " shape, can be inserted in the compound air duct plate 1.Make two " H " shape unorganic glass steel profile earlier, be coated with anticorrosion, fireproof phenol-formaldehyde resin modified layer 5 again on its top layer and make the unorganic glass steel profile and be connected bar 6.The cross section that during assembling two unorganic glass steel profile linking bar, 6 covers is bonded at two correspondences is on four limits of semicircular compound air duct plate, after cementing, is assembled into columnar glass fibre reinforced plastics ventilation pipeline.
