Description

Save the PLASTIC LAMINATED air conditioning wind pipe from damage

The utility model relates to the air pipeline in a kind of central air-conditioning system, and particularly a kind of fire-resistant, corrosion-resistant is saved the PLASTIC LAMINATED air conditioning wind pipe from damage.

Traditional iron sheet, galvanized steel plain sheet and glass fibre reinforced plastic blast pipe all exist perishable, the shortcoming of insulation, noise reduction, fire resistance difference, and composite air ducts such as at present glass wools that adopt, aluminium foil, fire proofing exist complex structure more, processing technology is various, weak strength, cost height, the shortcoming of waterproof, humidity resistance difference, and existing blast connection partly assembles loaded down with trivial detailsly, and efficiency of construction is low.

It is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, simple and convenient assembly, insulation, fire-resistant, anticorrosion, moistureproof, the impact strength performance is good saves the PLASTIC LAMINATED air conditioning wind pipe from damage.

The purpose of this utility model is achieved in that

A kind of PLASTIC LAMINATED air conditioning wind pipe of saving from damage comprises body, flange, it is characterized in that: body is for saving PLASTIC LAMINATED from damage, and its four corner angle vertically all are fixedly connected with inner protective corner and outer corner protector, and body is fixedly connected with flange on the two ends.Flange is provided with screw.

The utility model adopts that to save PLASTIC LAMINATED from damage be the airduct base material, processes through special process, compared with prior art has following advantage: external force resistance impact strength height, and fire-resistant, corrosion resistance is strong, waterproof, humidity resistance are good; Airduct inner wall smooth, indeformable, on-way resistance is similar to the iron sheet airduct, also has noise elimination, heat insulation function simultaneously, and simple in structure, and cost is low, can reduce investment outlay about 10%; Installing/dismounting is easy, improves efficiency of construction.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is an A-A view among Fig. 1;

Fig. 3 is a B-B view among Fig. 1.

The utility model is described in further detail below in conjunction with drawings and Examples: consulting shown in Figure 1ly, is a monomer structure of airduct among the figure, and air pipeline is to be installed by some such monomer airducts to link together.This air conditioning wind pipe mainly is by flange 1, inner protective corner 2, outer corner protector 5, body 6 grades constitute, its body 6 can adopt commercially available true qualities to save PLASTIC LAMINATED from damage and make, saving PLASTIC LAMINATED from damage is non-automatic incombustible material, in 24 ℃ water, soaked 48 hours, water absorption rate is less than 1.0%, and have good fire-resistant, waterproof, moistureproof, decay resistance, be processed into square type body 6 through special process, need not compound other material, on four corner angle of square type body 6, promptly vertically all be provided with inner protective corner 2 and outer corner protector 5 along its length, corner protector adopts angle bar to make, and works to strengthen the square type and saves PLASTIC LAMINATED body 6 bulk strengths from damage.The skin of saving PLASTIC LAMINATED body 6 in true qualities from damage also can spray colored coating.Two end faces of body 6 all are provided with flange 1, and flange adopts angle steel to make, and is square type shape, and several through holes are set on the vertical plane of flange 1, promptly are connected screw 3 between airduct and the airduct.

Consult Fig. 2, shown in Figure 3 simultaneously, several through holes also are set on the horizontal plane of flange 1, with bolt 4 flange 1 is connected firmly on the two ends of airduct body 6, its flange 1 is provided with sealing joint strip 7 with body 6 places of combining.Body 6 inside and outside inner protective corners that are provided with 2 and outer corner protector 5 also connect firmly together with body 6 by number support bolt 4, just the length difference of bolt 4.

Signal is installed as Fig. 3, adopts suspension bracket round steel 8 and suspension bracket angle steel 9, airduct is installed on the building, can be used for industry, civilian centralized air ventilation system by suspension bracket nut 10.
