Problems solved by technology

[0002] With the progress of society, the construction and decoration of houses are also getting more and more advanced. When large buildings are decorated, air ducts will be used to transport air and smoke through the air ducts, which is convenient for the exhaust and input of air and smoke. Traditional air ducts have The unit weight is large, the construction consumes a lot of auxiliary materials, the anti-corrosion and heat preservation are complicated, the construction requires more operators, the speed is slow, the air duct leakage rate is high, and the service life is short. In addition, the air duct is easy to rust during use. , Bacteria, and the quality of the air duct is unstable, all of which make the construction and application of the air duct have certain limitations

Embodiment 1

[0038] see figure 1 , the construction process of the inner thermal insulation metal air duct, including the following steps:

[0039] S1: Material preparation before construction, prepare the required air duct plates and tools required for construction;

[0040] S2: Draw drawings, drawings with appropriate quality and size according to the needs of the demander;

[0041] S3: Make the air duct, cut the board according to the proportion on the drawing, determine the cutting panel and cutting method, carry out batch panel blanking and cutting, the cutting method is bevel cutting or step cutting, made of polyurethane or phenolic The air duct made of material is cut by bevel cutting method, and the air duct made of glass magnesium or glass fiber material is cut by step cutting method. The bevel cutting method in the cutting method is that the two ends of the plate are respectively cut to 45 °Bevel angle, there are 0-3 90° bevel angles with openings facing upwards in the middle o...

Embodiment 2

[0053] The invention provides a technical solution: the construction process of the inner thermal insulation metal air duct, including the following steps:

[0054] S1: Material preparation before construction, prepare the required air duct plates and tools required for construction;

[0055] S2: Draw drawings, drawings with appropriate quality and size according to the needs of the demander;

[0056]S3: Make the air duct, cut the board according to the proportion on the drawing, determine the cutting panel and cutting method, and perform batch panel blanking and cutting. The cutting method is bevel cutting or step cutting, made of polyurethane or phenolic The air duct made of material is cut by bevel cutting method, and the air duct made of glass magnesium or glass fiber material is cut by step cutting method. The bevel cutting method in the cutting method is that the two ends of the plate are respectively cut to 60 °Bevel angle, there are 0-3 100° bevel angles in the middle...

Abstract

The invention discloses a construction technology of an internal thermal insulation metal air pipe, and belongs to the field of air pipe construction technologies. The construction technology of the internal thermal insulation metal air pipe comprises the steps of S1, material preparation before construction; S2, drawing; S3, manufacturing of the air pipe; S4, addition of a thermal insulation material; S5, bonding splicing of splicing plates; S6, reinforcement of the formed air pipe; S7, splicing of the formed air pipe; S8, detection of air leakage; S9, manufacturing of a hanging rod and a bracket; S10, marking of a mounting position; S11, mounting of the hanging rod and the bracket; S12, hoisting of the air pipe; and S13, construction completion. According to the construction technology,a processing method is more scientific and reasonable, the engineering construction period is greatly shortened during manufacturing and mounting of the air pipe, besides, manufacturing and mounting of nonmetal composite air pipes are convenient, fewer auxiliary materials are required, maintenance is easy, construction is convenient, construction cost is low, comprehensive economic benefits are good, leakproofness of the air pipe is greatly improved, air leakage of connectors and flanges is reduced, and besides, strength is high, corrosion resistance is achieved, and manufacturing and mountingquality is reliable.
