Abstract
The utility model relates to a rectangular ventilating duct, which is formed by that four independent inorganic glass fibre reinforced plastic composite panels are spliced; the internal angles of the splicing positions are supported by L-shaped splicers; the external angles of the splicing positions are coated by glass fibre cloth; when two ventilating ducts are connected, the connecting part is attached and fastened by a straight connecting piece. The utility model solves the defects of required integral transportation and installation, slow construction speed, high cost, etc. of the existing inorganic glass fibre reinforced plastic ventilating duct; the utility model has the advantages of convenient assembly and transportation, high sealing performance, flame resistance, and moisture resistance, construction quality is guaranteed, and construction speed is improved.
Description
The utility model relates to ventilation duct, particularly a kind of rectangle ventilation duct.
At present, be used for air conditioner ventilation on the modern construction engineering, the ventilation duct of vent systems and fire-fighting purging system mainly contains two kinds, a kind of steel plate type pipeline, its shortcoming be anticorrosion, fireproof performance is poor, speed of application is slow, another kind of inorganic glass-fiber reinforced plastic pipeline, and it is around the ventilation duct that forms by the molding bundle, though it has rotproofness, fire retardancy, moisture proofness preferably, but the cost of transportation height, speed of application is slow, and pipe thickness, deviation is big, price is high.
The purpose of this utility model is that a kind of speed of application of proposition is fast, convenient transportation, the rectangle ventilation duct that tightness is higher.
The utility model by four independently the unorganic glass steel composite board be spliced into the rectangle ventilation duct, its mutually the interior angle of splicing place " L " type splice supporting is arranged, and the exterior angle of splicing place has glass cloth to coat.
The ventilation duct that the above technology is spliced can be that straight tube shape, elbow are red, reducing shape, threeway shape etc.
The ventilation duct that the above is spliced when two ventilation ducts interconnect, coats "-" font link in the joint, and the fastening screw on it is fastened on link on the ventilation duct.
Adopt the above technology and since ventilation duct by four independently the unorganic glass steel composite board be spliced, assembly unit, convenient transportation have improved speed of application, have reduced the engineering time, and the unorganic glass steel composite board has corrosion resistant and fireproof performance.The interior angle of ventilation duct splicing place has " L " splice to be used for supporting, connects two plates, and there is glass cloth parcel at the exterior angle, can stick in preferably on the ventilation duct; Owing on ventilation duct, added " L " splice and glass cloth, increased the rigidity of pipeline, improved the sealability of pipeline.When the ventilation duct of a plurality of certain-lengths interconnected, its junction point had the fastening and coating of " one " font link.Make pipeline have good fire retardancy, moisture proofness, rotproofness, sealing; Make it be widely used in air conditioner ventilation, vent systems or fire-fighting purging system.The utility model assembly unit, convenient transportation, speed of application is fast, and is cheap.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross sectional representation of Fig. 1;
Fig. 3 is the structural representation that two ventilation ducts connect;
Fig. 4 is Fig. 3 cross sectional representation.
As shown in Figure 1, 2, the utility model is by four be spliced ventilation ducts 2 of rectangle of unorganic glass steel composite board 1 independently, flange is equipped with on its two top, and the interior angle of ventilation duct 2 has two adjacent composite sheets 1 of " L " type splice 3 supporting places, right angle, and the place, exterior angle is coated with glass cloth 4.
Shown in Fig. 3,4, when two splicing rear venting pipelines 2 interconnect, coat "-" font link 5 at junction point, and be fastened on the composite sheet 1 by fastening screw.
According to the above technological scheme, by four independently unorganic glass steel composite board 1 be spliced into rectangle ventilation duct 2, its ventilation duct 2 can be elbow shape, three-way shape, reducing shape etc.
