板材的切割均在自制加胡桃棕木層防火板工平臺上完成。在1段風管的同浪花白防火板一平面上盡量不拼接板材。

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.

為了提高加工效率，園野橡木防火板風管下料和切割要成批制作，形成流水線作業(yè)，即同一規(guī)格的風管平面板材集中加工，以加強各切割后板材的互換性，這樣既可以丹寧梭織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，板材下料和切割時，要注意板材的正反面，區(qū)別方法是：光滑面為正面，較粗糙面（有字香檳防火板面）為反面。

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.

根據(jù)風管強度的不同，其內(nèi)外都可以加設(shè)龍骨。單節(jié)風管制作時內(nèi)龍骨一端要伸出該管段200～300mm，另一端要縮進該銀縷衣防火板管段200～300mm，皎藍防火板以便在安裝時與另一節(jié)風管拼接緊月光白防火板密，并加強拼接強度。

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.

而外龍骨恰與內(nèi)龍骨相反，內(nèi)龍骨伸出的一晶點白防火板端外龍骨應(yīng)縮進50～100mm，內(nèi)龍骨縮進的一端外龍骨應(yīng)伸出50～100mm，同樣，這帆布白防火板種做法也為了使富白月光防火板美家防火板風管連接緊密，增加強度。

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.
