通風管道的施工，也是有很多的要求以及原則性的問題，今天濟南通風管道廠家給大家介紹幾點，在施工時比較通用的一些要求。

There are also many requirements and principled problems in the construction of ventilation pipes. Today, the manufacturer of ventilation pipes in Jinan will introduce some general requirements during construction.

1.對于比較復雜的民用建筑，在設計階段，各工種(暖通、給水排水，建筑)首先應協商好空間分隔，定出每種管道的標高范圍。一般情況下不得越出給自己規定的界限。

1. For more complex civil buildings, at the design stage, each type of work (HVAC, water supply and drainage, building discipline) should first negotiate the space separation and determine the elevation range of each type of pipe. Generally, you should not go beyond the limits set for yourself.

2.解決各種通風管道相碰及協調的原則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風管相撞，則應當自來水管拐彎。冷、熱水管與下水管相碰，則應改變冷、熱水管道。

2. The principle to solve the collision and coordination of various ventilation pipes is generally: "small pipes give way to large pipes, and pressure gives way to no pressure". For example, if the water pipe collides with the air pipe, the water pipe should turn. If the cold and hot water pipes collide with the downpipe, the cold and hot water pipes should be changed.

3.施工前，應將各工種的管線，單線畫在一張平面圖上。每種管道用一種彩色筆。在各交點處綜合其標高，看是否有矛盾之處，及時發現，將問題解決在安裝之前。

3. Before construction, the pipeline and single line of each type of work shall be drawn on a plan. Use a color pen for each type of pipe. The elevation of each intersection shall be integrated to see if there is any contradiction, and the problem shall be solved before installation.

在風管加工中間，遇到比較長的風管，那我們在施工時候，應該注意哪些呢?

In the process of air duct processing, we encounter relatively long air ducts. What should we pay attention to during construction?

1.超長風管的制作(大于1.2m)：長風管制作時重要的就是要做好：合理拼板，降低損耗，錯開接縫，在同一平面盡量只有一塊拼接，成型后風管底邊兩角在安裝時應用30?0角鋼固定再緊固。較長的風管在安裝時，是不能有縫隙出現的，在連接時候，必須緊湊。

1. Fabrication of super-long air duct (more than 1.2m): The important thing to do during the fabrication of long air duct is to do a good job: reasonable splicing, reduce loss, stagger joints, try to have only one piece of splicing in the same plane, and apply 30? 0 Angle steel is fixed and then tightened. When installing the long air duct, there should be no gap, and it must be compact when connecting.

2.吸頂安裝時將風管上部用損耗的條狀保溫板兩層粘貼在風管支架上方緊固，不吸頂安裝時則用全牙鏍桿下掛，風管上下用角鋼固定。

2. During the ceiling installation, the upper part of the air duct shall be pasted with two layers of lost strip insulation board on the upper part of the air duct support for fastening. When the air duct is not mounted on the ceiling, it shall be hung down with full-tooth screw rod, and the upper and lower parts of the air duct shall be fixed with angle steel.
