Abstract
The utility model relates to a multifunctional compound ventilation duct. Fibrous reinforcement inorganic cementitious material is solidified to be a rigid airtight outer protection layer which is connected to a heat-isolating noise-eliminating middle layer which is made of ultra-fine fiberglass plates by fibrous reinforcement inorganic adhesive. The heat-isolating noise-eliminating middle layer is fixedly connected to a fiberglass cloth inner liner by fireproofing adhesive. The utility model which can resists static pressure to achieve 200 mm water column and conforms to the national noncombustible material standard has the advantages of good effects of heat preservation, thermal insulation, noise elimination and sound insulation, high intensity of ventilation ducts, favorable fireproof performance of ventilation ducts, no heat-isolating and noise-eliminating material dispersion, easy machining and installation and long service life. The utility model is suitable for the ventilation ducts of various air-condition systems to use.
Description
The utility model belongs to the ventilation duct in the construction engineering ventilation and air conditioning system, particularly has the ventilation duct of insulation, heat insulation, noise elimination, sound insulation effect.
At present, the conventional practice of the ventilation duct in the air-conditioning system is that employing iron sheet airduct, organic or inorganic glass fibre reinforced plastic blast pipe are the main body pipe, adds thermal insulation layer and damp proof insulation layer, in order to the air temperature and the humidity of being carried in the holding tube; Simultaneously in system, also silencing apparatus to be set.There is more shortcoming in this air conditioning wind pipe system, and as the volume heaviness, processing difficulties is installed trouble, and cost is higher, and external thermal insulation is fragile, owes attractive in appearance, and heavy silencing apparatus must be set, and is difficult for eliminating for the secondary noise that air flows produced in the airduct.
The purpose of this utility model is, a kind of ventilation duct that is combined into by insulation, fire prevention, reinforcing fibre material is provided, make it have good insulation, heat insulation, the multiple function of eliminating the noise, insulate against sound,, become a kind of novel airduct that gathers multi-function in integral whole to overcome the shortcoming of airduct at present commonly used.
Composite multi-functional ventilation duct of the present utility model, form by outer protective layer, insulation noise elimination mesosphere, inside liner, it is characterized in that, strengthen cement inorganic material by fiber and be solidified into the airtight outer protective layer of rigidity, with have fiber to strengthen inorganic adhesive between the insulation noise elimination mesosphere that super-fine glass fiber board is made to be connected, between insulation noise elimination mesosphere and the glass fibre cloth inside liner, there is the fire prevention adhesive to connect.
Fiber in the outer protective layer of composite multi-functional ventilation duct can be a glass fibre, Steel Fibre, hair fiber, glass fibre cloth;
The outer protective layer of composite multi-functional ventilation duct can be the iron sheet outer protective layer, is provided with the flanging of reinforcing the termination at two ends, and constitutes the groove that connects adhesive tape;
The insulation noise elimination mesosphere of composite multi-functional ventilation duct can be a rock cotton board, styrofoam;
The inside liner of composite multi-functional ventilation duct can be the fire prevention sticker layer, the clad aluminum foil layer;
The flange plate that bolt connects usefulness can be established in the two ends of composite multi-functional ventilation duct, or establishes the adhesive tape connecting groove;
Composite multi-functional ventilation duct of the present utility model, its making method is:
For the composite multi-functional ventilation duct of the airtight outer protective layer of rigidity, at first inside liner and insulation noise elimination mesosphere are combined into composite sheet with the fire prevention tackiness agent, and composite sheet is made internal lining pipe, then outside internal lining pipe, the airtight outer protective layer of direct compound rigidity.
Composite multi-functional ventilation duct for the iron sheet outer protective layer, adopt secondary to become the plumber to plant, at first be processed into the outer pillar of iron sheet flanged or the band flanging with iron sheet, then inside liner and insulation noise elimination mesosphere are combined into composite sheet with the fire prevention tackiness agent, and composite sheet made internal lining pipe, the 3rd goes on foot, and adopts the fire prevention tackiness agent, internal lining pipe is glued be enclosed within the outer pillar of iron sheet.
The utlity model has following advantage: owing to adopt insulation, fire prevention, reinforcing fibre material to be composited, have good insulation, heat insulation, noise elimination, defening effect; The intensity height of airduct, anti-static pressure can reach 200 column; The airduct fireproof performance is good, meets national non-automatic incombustible material standard; Do not have the insulation muffler material and peel off and the phenomenon of dispersing, aging quality resistance is good, long service life, and installation and processing is convenient, and cost is low; Effectively overcome the shortcoming of present China airduct commonly used.Be applicable to the ventilation duct in the various air-conditioning systems.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the tectonic maps of composite multi-functional ventilation duct
Fig. 2 is that the two ends of composite multi-functional ventilation duct are provided with the flange plate tectonic maps
Fig. 3 is the adhesive tape joint construction figure of composite multi-functional ventilation duct
Fig. 4 is that the outer protective layer of composite multi-functional ventilation duct is an iron sheet outer protective layer tectonic maps
As seen from the figure, composite multi-functional ventilation duct of the present utility model, form by outer protective layer, insulation noise elimination mesosphere, inside liner, it is characterized in that, strengthen cement inorganic material by fiber and be solidified into the airtight outer protective layer 1 of rigidity, with have fiber to strengthen inorganic adhesive between the insulation noise elimination mesosphere 2 that super-fine glass fiber board is made to be connected, between insulation noise elimination mesosphere and the glass fibre cloth inside liner 3, the connection of the adhesive of fire prevention is arranged.
When the outer protective layer of composite multi-functional ventilation duct is the iron sheet outer protective layer, be provided with the flanging 6 of reinforcing the termination at two ends, and constitute adhesive tape 5 connection grooves;
The flange plate 4 that bolt connects usefulness is established at the two ends of composite multi-functional ventilation duct, or establishes adhesive tape 5 connecting grooves.
