Abstract
The utility model relates to a ventilating duct which is suitable for ventilation and fume exhaust prevention ventilating duct systems. The fire prevention performance is good, the intensity is high, the utility model has no corrosion, no rustiness, and no air leakage, the service life is long, the energy can be saved, and the utility model can be produced on a mechanized scale. A pipe wall (1) is produced by compounding inorganic cementing material and glass fiber, the inner angle or the outer angle of the edge angle of a pipe body is stuck on the pipe body by adopting an angle-type connecting piece (2), and the angle-type connecting piece and the pipe wall are produced by material of identical texture.
Description
Technical field
The utility model relates to the anti-smoke evacuation and the supply air duct of the ventilation system, particularly fire-fighting special use of industrial and mining enterprise, Building Building etc.
Background technique
At present, used ventilation duct adopts galvanized iron sheet substantially both at home and abroad, or magnesia oxychloride cement " glass fibre reinforced plastics " home built airduct.Facts have proved that all there is serious defective in the ventilation duct that adopts these two kinds of materials to make.The galvanized sheet ventilation duct exists inleakage big, and is not energy-conservation, and the noise height easily gets rusty, and is perishable, and working life is short, the cost height.The difficult control of magnesia oxychloride cement home built airduct prescription, intensity is low, easy anti-halogen, easy-weathering collapses, the difficult control of quality, manufacturing schedule is long, is difficult for long distance and transports, and can not scale produce in batches.
Summary of the invention
It is short, not energy-conservation that the utility model will solve ventilation duct working life, unstable product quality, fire performance is poor, intensity is low, can not the scale batch process etc. the many problems of thread.The utility model provides a kind of ventilation, anti-smoke evacuation pipe special for this reason.This ventilation duct can address the above problem preferably.
For addressing the above problem, the technical solution adopted in the utility model is: to be multiple inorganic material make through mechanization is compound its tube wall, its special way is the interior angle or the exterior angle of body edges and corners, the rectangle ventilation duct of two kinds of different structures of bonding rectangular shape link.
Tube wall described in the utility model adopts silicon magnesium inorganic coagulation material, glass is compound makes.
Angle type link in the utility model is that homogeneous material is made with described tube wall.
The beneficial effects of the utility model are that its tube wall adopts inorganic coagulation material, glass to strengthen.So fireproof performance is good, intensity height, corrosion-resistant non-corrosive, long service life, be convenient to mechanical mass production, again because the angle type link that has homogeneous material to make is bonded in the edges and corners of body with inorganic glue, thereby improved the bond strength of body edges and corners greatly, the seal of body is improved, body is air tight, and is effective.

Figure acceptance of the bid preface 1 is the ventilation duct tube wall, the 2nd, and the angle type connects reinforcer.
Embodiment:
Ventilation of the present utility model, its tube wall of the special-purpose ventilation duct of anti-smoke evacuation are that inorganic coagulation material, glass enhancing are composited through mechanization, exterior angle or interior angle place at body are bonded with angle type connection reinforcer, and the angle type connects reinforcer and the tube wall homogeneous material is made.The angle type connects reinforcer and tube wall is overlapped to form rectangular duct in regular turn.
Claims (2)
1. a ventilation, the special-purpose ventilation duct of anti-smoke evacuation, it is characterized in that: the tube wall of ventilation duct (1) adopts inorganic coagulation material, glass to strengthen making, and it is characterized in that the interior angle of ventilation duct edges and corners or exterior angle adopt angle type link (2) to be bonded on the body.
2. ventilation according to claim 1, the special-purpose ventilation duct of anti-smoke evacuation is characterized in that rectangular shape link (2) adopts inorganic coagulation material, glass to strengthen through compound and make.
