Embodiment 1

[0052] The construction method of the machine-made glass-magnesium composite board air duct provided in this embodiment includes the following steps:

[0053] (1) Air duct sheet cutting

[0054] 1) The cutting of rectangular plates should use a platform cutting machine, the cutting line of the plate should be straight; the cutting surface and the plate surface form an angle of 90°, and the length error of the diagonal length of the standard plate after cutting should be less than 3mm.

[0055] 2) After the specification board is cut, the step line of the board is made, and the cutting machine blade adjusts the cutting depth according to the thickness of the board (δ=25mm), so that the FRP protective layer on the other side will not be damaged when the board is cut. Use a scraper to scrape off the insulation layer outside the step line. The step should be at a right angle of 90°, the width is the thickness of the plate, and the cutting surface should be flat and even.

Embodiment 2

[0084] Embodiment 2 engineering example

[0085] (1) The main management project of the International Exchange Center of China Petroleum Equipment Industry Base

[0086] The main management of the International Exchange Center of China Petroleum Equipment Industry Base is located in Dongying City, Shandong Province, with a construction area of ​​52,754㎡, 5 floors above ground, 1 floor underground, a building height of 37.5m, and an air-conditioning building area of ​​30,322㎡. The central air-conditioning system of this project uses 4 sets of screw-type soil-source ground-source heat pump units to provide hot and cold water for air-conditioning, and the ventilation, air-conditioning and smoke control systems all use mechanism-made glass-magnesium composite board air ducts. Among them, the air supply and return ducts of the air conditioning system adopt energy-saving ducts, marked as MFR-PX-2260×1300×31; the exhaust ducts, smoke exhaust ducts and pressurized air supply ducts ado...

Abstract

The invention discloses a construction method for machine-made glass magnesium composite plate air pipes. The construction method comprises the following steps that (1) plates of the air pipes are cut; (2) the air pipes are spliced; (3) the air pipes are hoisted and connected; and (4) parts of the air pipes are mounted. Compared with a tradition construction method for a galvanized steel plate airpipe, the construction method for the machine-made glass magnesium composite plate air pipes has the characteristics of less construction machines, simple construction procedures, less auxiliary material using amount, small floor space, short construction period and the like. Due to the fact that the air pipes are connected without flanges, a large amount of engineering materials such as angle steel, gaskets, bolts, welding rods, rivets, oxygen and acetylene can be saved; and the average construction efficiency of the galvanized air pipe is 3 m<2> / d per person, the average construction efficiency of the machine-made glass magnesium composite plate air pipes can reach to 12.1 m<2> / d per person, and as for manufacturing and mounting of the air pipes with the same area, the construction period can be shortened obviously for the machine-made glass magnesium composite plate air pipes.

Description

technical field [0001] The invention relates to a construction method of a machine-made glass-magnesium composite board air duct, which belongs to the technical field of building construction. Background technique [0002] Central air-conditioning systems are more and more widely used in modern buildings, but there are many shortcomings in traditional air ducts. The galvanized steel air duct is easy to rust, has no heat insulation and noise reduction function, the production process is complicated, and the installation period is long; the inorganic glass fiber reinforced plastic air duct is corrosion-resistant but the body is heavy, easily deformed and cracked by its own weight, and has no heat insulation and noise reduction function , The production and installation period is long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a construction method for air ducts of machine-made glass-magnesium composite board...
