Abstract
Disclosed is an energy-saving silencing fire-retardant damp-proof air duct. The inner surface of a casing of the energy-saving silencing fire-retardant damp-proof air duct is coated with one layer of fire-retardant damp-proof adhesives, a glass cloth compounding one layer of perforation or no-perforation aluminum foil or the glass cloth coating with only one layer of fire-retardant damp-proof adhesives, the outer surface of the air duct casing is coated with one layer of fire-retardant damp-proof adhesives or two glass cloth layers, one adhesive layer, a glass cloth compounding one layer of perforation aluminum foil or the glass cloth coating with one layer of fire-retardant damp-proof gum according to the thickness of the adhesives, reinforcing rods and abnormal type reinforcing fittings are plunged in the horizontal and the vertical walls of the air duct casing, and the outer surface of the air duct casing is wrapped tightly with n-shaped outboard reinforcing rods. The utility model has the advantages of small duct resistance, strong bearing pressure, good heat preservation compared with the steel plate air duct and the air duct of glass fibre reinforced plastic and saving construction investment about 40%. The utility model is the optimal air duct of saving the energy, retarding the fire and stopping the noise in the modern architecture.
Description
The utility model belongs to the energy-saving damping fire-proof and damp-proof air channel of energy-saving structure in the air conditioner ventilation engineering.
In order to make the air channel in the air conditioner ventilation engineering reach energy-saving effect, the traditional method in air channel is: add insulation material after the construction of steel plate air channel finishes, add the two-layer brush fire resistant coating of glass wool cloth twice then, install insulation material additional before or after the construction of fiberglass air channel, be generally and add insulation between layer glass, facts have proved that these two kinds of way one-time investments are big, that making and on-site installation work amount be installed in trouble, the factory is big, very big gap pad resistance is arranged between insulation material and the air channel, and the secondary noise of the mobile output of the air in the air channel is difficult for eliminating.This air-conditioning system also must be joined expensive silencing equipment, is difficult to people's will to the greatest extent with the completion various quality assurance in back in the installation process in a word.Also have the various mineral wool airducts of exploitation at present, have plenty of the air channel inwall and do not have the damp proof insulation fireprotection layer.Install large-scale bugle steel after the air channel that has installs additional, use national structure of steel product unreasonable in a large number.Unnumbered steel bar rod support is housed in the air channel that has, looks the section such as the birdcage in air channel, and unnumbered fixing point is arranged, screw and nut outside the air channel.The damp proof insulation layer is externally done in the air channel that has, and makes the difficult evaporation of moisture content in the air channel.The air channel that has does not have the connection way, and quality can't be supervised, and the user is worried.The air channel inwall that has is equipped with unnumbered bright dress angle steel card and reinforcing bar card, is furnished with unnumbered large size nut and screw again, spends big watchman's wooden clapper air channel as five, and the waste steel influence attractive in appearance.It is that it is attractive in appearance that influence is installed outside exposed channel-section steel mouth dashed that the bright dress of air channel outer wall that also has adds retainer plate.All time all to rationally utilizing China's steel, rationally utilize China's mineral wool to do air channel various degrees waste and cover disease.
This use novel (Fig. 1) (Fig. 2) has overcome above-mentioned whole shortcoming.Has good hardness of steel, but static pressure≤160MMH20 post, gap pad resistance is zero substantially, air channel shell inwall fire-proof and damp-proof, resistance is little, because the aluminium foil layer of air channel inner surface has added numerous perforation, the noise elimination effect is very good, general 10 meters long air channels can make 100 decibels noise source drop to about 55 decibels, and air channel outer wall rinforcement bar is a ㄇ shape band shape, it and air channel glue very tight, aesthetic in appearance, level and vertical direction have all been established submersible rinforcement bar and special-shaped accessory in the wall of air channel shell, and be not only firm but also attractive in appearance, and the outer surface fiery damp-proof layer of setting up defences all more can reduce cost than any way in the past.General reduce air channel investment about 40%, air channel shell section inside and outside and can't see place's pull bar, angle steel, screw and nut all around, compact conformation is practical and attractive.The utility model accomplishes really that energy-saving damping fire-proof and damp-proof, pressure-bearing height, resistance are little, low price, elegant in appearance, hydroscopicity for≤1%, be beneficial to installation, not only can do square, rectangle, circle, flaring convergent shape and elbow-shaped, and can do threeway four-way shape.Of the present utility model adding with steel plate air channel and fiberglass air channel, compared saving one-time investment 35-40% when being incubated.Purpose of the present invention that Here it is.
