板材的切割均在自制加胡桃棕木层防火板工平台上完成。在1段风管的同浪花白防火板一平面上尽量不拼接板材。

The cutting of the board is all completed on a self-made platform with walnut brown wood layer fireproof board. Try not to splice the same wave white fireproof board on the same plane as the first section of the air duct.

为了提高加工效率，园野橡木防火板风管下料和切割要成批制作，形成流水线作业，即同一规格的风管平面板材集中加工，以加强各切割后板材的互换性，这样既可以丹宁梭织防火板提高材料的利用率，也可以提高施工效率。

In order to improve processing efficiency, the cutting and cutting of the air duct of Yuanye Oak Fireproof Board should be done in batches, forming an assembly line operation. That is, the same specification of flat air duct panels should be processed in a centralized manner to enhance the interchangeability of each cut panel. This can not only improve the material utilization rate of Danning Woven Fireproof Board, but also improve construction efficiency.

另外，板材下料和切割时，要注意板材的正反面，区别方法是：光滑面为正面，较粗糙面（有字香槟防火板面）为反面。

In addition, when cutting and cutting the board, attention should be paid to the front and back sides of the board. The difference method is: the smooth surface is the front side, and the rougher surface (champagne fireproof board with characters) is the back side.

根据风管强度的不同，其内外都可以加设龙骨。单节风管制作时内龙骨一端要伸出该管段200～300mm，另一端要缩进该银缕衣防火板管段200～300mm，皎蓝防火板以便在安装时与另一节风管拼接紧月光白防火板密，并加强拼接强度。

Depending on the strength of the air duct, keels can be added both inside and outside. When making a single section of air duct, one end of the inner keel should extend out of the duct section by 200-300mm, and the other end should be retracted into the silver wire clothing fireproof board section by 200-300mm. The bright blue fireproof board should be used to tightly connect with the other section of air duct during installation, and the splicing strength should be strengthened.

而外龙骨恰与内龙骨相反，内龙骨伸出的一晶点白防火板端外龙骨应缩进50～100mm，内龙骨缩进的一端外龙骨应伸出50～100mm，同样，这帆布白防火板种做法也为了使富白月光防火板美家防火板风管连接紧密，增加强度。

The outer keel is exactly the opposite of the inner keel. The outer keel at the end of the white fireproof board protruding from the inner keel should be retracted by 50-100mm, and the outer keel at the end of the inner keel should be extended by 50-100mm. Similarly, this canvas white fireproof board method is also used to make the rich white moonlight fireproof board Meijia fireproof board air duct connected tightly and increase strength.
