在不少場景中，大家可能會見到，有些工作人員在安裝一些圓形或者矩形的通風管。它其實是用于空氣輸送和分布的管道系統，為人們帶來了很多便利。下面來看看金屬板制風管加固的七點事項吧。
In many scenes, you may see that some staff are installing some circular or rectangular ventilation pipes. It is actually a pipeline system used for air transmission and distribution, which brings a lot of convenience to people. Let's take a look at the seven points for strengthening the metal plate air duct.
1）風管大邊尺寸在630～1000mm時，直接在生產線壓筋加固，排列應規則，間隔應均勻，板面不應有明顯的變形。
1) When the size of the large side of the air duct is 630~1000mm, the reinforcement shall be directly pressed on the production line, the arrangement shall be regular, the spacing shall be uniform, and the plate surface shall not have obvious deformation.
2）當
濟南通風管道大邊尺寸在1000mm以上時，可采用角鋼、扁鋼、鋼管、Z形槽、加固筋、通絲螺桿等進行管內外加固。
2) When the large side size of Jinan ventilation pipe is more than 1000mm, angle steel, flat steel, steel pipe, Z-shaped groove, reinforcing bar, through-wire screw, etc. can be used to reinforce the inside and outside of the pipe.
3）角鋼或加固筋的加固，其高度應小于或等于風管法蘭高度，排列應整齊，間隔應均勻對稱，且不大于220mm，與風管的鉚接應牢固。
3) For the reinforcement of angle steel or reinforcing bar, its height should be less than or equal to the height of the air duct flange, the arrangement should be neat, the spacing should be uniform and symmetrical, and not more than 220mm, and the riveting with the air duct should be firm.
4）管內用通絲螺桿支撐加固，其專用墊圈對外保溫風管置于風管內壁，對不保溫風管或內保溫風管，則放在風管外壁，通絲螺桿宜設置在風管處，風管斷面較大時，應在靠近法蘭的兩側各加一根通絲螺桿支撐加固。
4) The inner part of the duct shall be supported and reinforced with through-wire screw. Its special gasket shall be placed on the inner wall of the duct for external insulation. For non-insulated duct or internal insulation duct, it shall be placed on the outer wall of the duct. The through-wire screw shall be set at the center of the duct. When the duct section is large, a through-wire screw shall be added on both sides near the flange for support and reinforcement.
5）濟南通風管道斷面＞1250*630時，為了保持相鄰壁面互相垂直，宜在風管內四角采用90℃斜支撐加固。
5) When the section of Jinan ventilation duct is more than 1250 * 630, in order to keep the adjacent walls perpendicular to each other, 90 ° C diagonal bracing should be used at the four corners of the air duct for reinforcement.
6）中壓和高壓系統風管，其長度大于1250mm時，應采用加固框補強。
6) When the length of the air duct of the medium-pressure and high-pressure systems is greater than 1250mm, the reinforcement frame shall be used for reinforcement.
7）金屬板制通風管道組裝加固規格表。
7) Specification for assembly and reinforcement of metal sheet ventilation duct.
注意：在對通風管道進行安裝之前，人們需要先對通風管道的情況做具體的了解，看看通風管道的各項指標是否合格，保證通風管道的排風口具有一個平整的表面，那個平整的表面可能在制作上有相應的誤差，但誤差須控制在2毫米，如果排風口的誤差大于2毫米，那就說明通風管道是不合格的，這種通風管道不能使用。更多相關事項就來我們網站

Note: Before installing the ventilation duct, people need to make a specific understanding of the condition of the ventilation duct, see whether the indicators of the ventilation duct are qualified, and ensure that the exhaust port of the ventilation duct has a flat surface, which may have a corresponding error in manufacturing, but the error must be controlled at 2mm. If the error of the exhaust port is greater than 2mm, it means that the ventilation duct is unqualified, This ventilation duct cannot be used.
