Embodiment 1

[0020] like figure 1 As shown, first of all, be familiar with the drawings and site survey, and then sort out the bill of materials and prepare the materials. Clean all the duct plates used, and then loft and cut them, and clean the cut edges after cutting. The key points of composite air duct blanking are as follows:

[0021] 1) The cutting line should be straight, and the error of the diagonal length of the air duct plate should be less than 5mm.

[0022] 2) After cutting, clean the cut edges.

[0023] 3) The cutting board must form a 90° angle with the panel.

[0024] After the cutting is completed, check the cut panels to be assembled, that is, check whether their length, width and adjacent side angles meet the requirements.

[0025] Assemble and glue the cut panels. The main points of composite air duct prefabrication are as follows:

[0026] 1) Prepare magnesia powder and magnesia halogen flakes at a weight ratio of 10:6, dissolve the magnesia flakes in water and m...

Abstract

The invention relates to the technical field of the construction of a composite wind pipe in an air conditioner system. The GM-III composite wind pipe construction method provided by the invention comprises the steps as follows: firstly, labor and materials are prepared according to a drawing and the field condition, and sheet materials are cleaned; then the materials are lofted and cut, the cut edges are cleaned after cutting; the cut sheet materials are checked by a tape and a square; subsequently, a wind pipe is prefabricated by assembling and bonding; and finally, the wind pipe is installed. The construction method disclosed by the invention has mature technology, simple construction, convenient operation and reliable quality. At the same time, the construction has short construction period and fast speed, and the proficiency of the worker is high, so that the labor productivity is high, and the construction method has good economic benefit. The invention has wide application range and can be applied to the occasions of national defense system, industrial system, civil system, etc.

Description

technical field [0001] The invention relates to the technical field of construction of composite air ducts in ventilation and air conditioning systems. Background technique [0002] Most of the current ventilation and air-conditioning ducts use galvanized iron sheets, and GM-III composite air ducts are a new type of green and environmentally friendly air ducts that replace galvanized iron sheets. The construction process and construction points have not yet been formulated and disclosed.
