Nonmetal composite air pipe construction process

Abstract

The invention discloses a nonmetal composite air pipe construction process and belongs to the technical field of building installation engineering. The process disclosed by the invention comprises the following steps of: preparing panels and tools which are used for manufacturing an air pipe, wherein during the manufacture, reasonable cutting and blanking are carried according to nonmetal composite air pipe specifications on design paper, a glue connection structure is adopted, a plurality of air pipes are obtained by air pipe reinforcing, the air pipes are in non-flange or flange connection, and the air pipes are connected with valve pieces and other matching devices by special flanges; and installing timely after finishing the manufacture of the nonmetal composite air pipe, and detecting a nonmetal composite air pipe system. The nonmetal composite air pipe construction process disclosed by the invention can be used for simplifying the construction procedures, reducing the construction difficulty continuously, and greatly improving the labor production efficiency so as to be easier to expand and apply in construction sites; and compared with the construction technology of the similar traditional metal air pipe and the inorganic glass fiber reinforced plastic air pipe, the nonmetal composite air pipe construction process has the advantages that the construction period is shorter, the engineering quality is more reliable, the construction cost is more economical, and products are more energy-saving and more environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of building installation engineering, and in particular relates to a non-metallic composite air duct construction process with short construction period, reliable engineering quality, economical engineering cost, energy-saving and environment-friendly products. Background technique [0002] The traditional galvanized iron sheet air duct and inorganic glass fiber reinforced plastic air duct have been used until now because of their excellent properties such as high air duct strength, strong wind pressure resistance, and fire resistance level reaching non-combustible A level. However, the traditional galvanized iron plate air duct and inorganic glass fiber reinforced plastic air duct also have a large unit weight of the air duct, consume a lot of auxiliary materials in the construction, complex anti-corrosion and heat preservation, a large amount of labor is consumed in the construction, the speed is slow, and ...

Problems solved by technology

However, the traditional galvanized iron plate air duct and inorganic glass fiber reinforced plastic air duct also have a large unit weight of the air duct, consume a lot of auxiliary materials in the construction, complex anti-corrosion and heat preservation, a large amount of labor is consumed in the construction, the speed is slow, and the air leakage rate of the air duct is high. Common disadvantages such as short life, in addition, galvanized iron air ducts are prone to rust and bacteria during use, and the quality of inorganic FRP air ducts is unstable. All these make the construction and application of galvanized iron air ducts and inorganic FRP air ducts have certain limitations. sex

[0003] The non-metallic composite air ducts that have appeared in recent years, such as glass magnesium composite air ducts, polyurethane composite air ducts, phenolic composite air ducts and glass fiber composite air ducts, use certain strength air duct surface materials (inner and outer layers) and air ducts. The thermal insulation material (core layer) is directly compounded. This composite air duct not only has non-combustible Class A fire performance, but also ensures the strength and pressure resistance of the air duct. It can be popularized and applied in building construction, but there are still complete Construction technology, its application in building construction has certain difficulties, so inventing a non-metallic composite air duct construction technology that is convenient for construction has become one of the important problems to be solved by construction industry technicians
