Technical field
The utility model is related to ventilation shaft connection area, more particularly to a kind of enhanced company of composite air duct ventilation shaft
Connection device.
Background technology
As central air-conditioning becomes increasingly popular, the demand of ventilation shaft is also increasing, because the length of ventilation shaft is
According to the distance of ventilation distance, the system that airduct is formed by connecting is saved by a section, so needing to use flange in its joining place
It is fixedly connected.Be presently used for connecting the flange of airduct also have it is many in, as PVC flanges, aluminium alloy flange, angle steel flange and altogether
Plate flange etc., wherein angle steel flange is commonplace, and the flange is made by various sizes of angle steel, is needed after making
Punch, then several sections of airducts are linked together with bolt, the stability of angle steel flange is good, can meet state on monolithic flange
Small requirement is deformed in mark to rectangular air duct physical dimension, but its manufacturing procedure is complicated, expends man-hour greatly, intensity is weak, heavy caliber
Need reinforcement, cost is also higher.Especially the centre bore of flange bolt is away from easily there is deviation, so as to field joint wind
Pipe bringing many unexpected difficulties, cause effect bottom and labour cost increase, it is exactly some angle steel flange needs to also have
Cumbersome welding, and the weld bond that also to polish after having welded, carry out surface layer preservative treatment etc. and waste substantial amounts of artificial and influence
Construction speed.Secondly adpting flange material used in composite plate material airduct typically has angle steel, aluminium to close in ventilation and air conditioning engineering at present
Gold and PVC flange profiles, not only cost is high for the flange made of angle steel and aluminium alloy, and manufacturing procedure is complicated, easily produces
Pitch-row deviation, difficulty is brought to installation, and the interchangeability with bore flange is very poor；And use the flange of PVC materials to use work
Word slip-type, card article formula and hook lock formula connected mode, but I-shaped slip-type and card article formula structure are used due to by duct length
And the limitation of installation site, installation difficulty, be difficult to be inserted into position, simultaneously because PVC materials in itself exist have to environment pollution into
Point, health of human body is impacted, and burning grade is only fire-retardant simultaneously for the easy aging of PVC material flanges, does not reach fire-fighting
The non-ignitable grade that height rule require, therefore can not popularize；If doing flange material with common galvanized sheet, although with low cost,
But light does flange with it and there is insufficient strength, is easily deformed, so that interchangeability is affected；Therefore, one kind how was provided both
With low cost, environmentally friendly, interchangeability is good, without the need for welding, independent assortment, and connection flange long lifespan, intensity it is big and
And burning grade turns into air conditioner industry for the wind tube connecting device of non-ignitable A ranks and is badly in need of the problem to be solved.
