Embodiment 1

[0051] The installation method of a kind of phenolic composite air duct of the present invention uses the straight pipe length≤4000mm of each phenolic composite air duct, and the size of each phenolic composite board is 3m×1.2m×20mm, and is characterized in that it comprises the following steps:

[0052] a. Cutting

[0053] According to the size of the air pipe, choose to install it in the vertical and horizontal directions, so that the longest length of each straight pipe is 4000mm and 1200mm respectively, so as to achieve the optimization of materials and labor;

[0054] b. cutting

[0055] (1) The incision of the phenolic composite board should be accurate, and the tangent line should be straight or follow the line;

[0056] (2) The incision of the phenolic composite board should be smooth and free of damage;

[0057] (3) The dimensions of the diagonals of the rectangular air duct should be consistent, with an error of ≤1.5mm. The two adjacent surfaces of the air duct sho...

Abstract

The invention provides an installation method of phenolic aldehyde compound air hoses. The straight pipe length of each phenolic aldehyde compound air hose is smaller than or equal to 4,000 mm, and the size of each phenolic aldehyde composite board is 3 m*1.2 m*20 mm. The installation method is characterized by comprising steps as follows: a, blanking; b, cutting; c, glue dispensing; d, bonding; e, sealing; f, air hose strengthening; g, connecting installation of the air hoses. The installation method of the phenolic aldehyde compound air hoses has the advantages that connection between the air hoses is performed conveniently and rapidly, the air hoses are sealed and bonded by the aid of inserting slots and inserting strips, and tightness of an air conditioning ventilation system and the rigidity of the air hoses are guaranteed through dispensing of bonding glue/sealant.

Description

technical field [0001] The invention relates to an installation method of an air-conditioning air duct, in particular to an installation method of a phenolic composite air duct. Background technique [0002] The Star River Hotel project in Guiyang New District started construction on December 15, 2013. The contract stipulates that the absolute construction period is only 6.5 months, including piling time. The time left for installation is less than 2 months, and the air duct installation time of the air conditioning system is even shorter. Due to the short construction period, many working procedures and possible emergencies, the design institute changed the material of the air-conditioning system air duct, and changed the hot-dip galvanized steel sheet into a phenolic composite air duct. Cutting, gluing, joining and other work created a series of difficulties. [0003] Therefore known hot-dip galvanized steel sheet uses the processing of phenolic composite air duct instea...
