1、图纸已经熟悉,并且经过图纸会审。对建筑、结构和电气、暖卫施工图中的管路走向、坐标、标高与通风管道之间跨越交叉在图纸上出现的问题已经有解决方案。

1, are familiar with drawings, drawings and after. For building, structure and electrical and heating protection drawings, pipeline crossing, coordinate, elevation and ventilation pipeline crossing over and crossing problems on drawings have been solved.

2、材料表面油污应全部清除干净,以免铁锈或氧化物落于材料表面产生局部腐蚀。

2, the surface of the material should be cleaned completely, so as to prevent the rust or oxide from falling on the surface of the material to produce local corrosion.

3、必须有一个单独的加工场地,为了不破坏镀锌钢板外的保护膜,工作场地最好铺设木板或者橡胶板,保持场地清洁。

3, there must be a separate processing site. In order not to destroy the protective film outside the galvanized steel sheet, it is best to lay wooden boards or rubber sheets in the workplace, so as to keep the field clean.

4、已进行了施工技术交底,对风管制作的尺寸,采用的技术标准、接口及法兰连接方法已经明确。并且已经作好施工交底记录。

4. The construction technology has been carried out. The size of the wind pipe, the technical standard, the interface and the flange connection method have been made clear. And it has made good record of the construction.

根据风管长边尺寸进行合适的选料。按正确的放样进行制作。

Suitable materials according to the wind pipe edge size. Make it according to the correct lofting.

风管翻边时,翻边应留有不小于6mm的余量,翻边不能遮住螺栓孔,咬口边要用剪刀进行倒角或开角,且不开裂,形成弧形翻边。若翻边四角开裂,应采用锡焊或密封胶填补,防止风管漏风风管板材厚度小于1.2mm时可以采用联合角或按扣式咬口,大于1.2mm时采用焊接。

When the air pipe is flanging, the margin should be kept not less than 6mm. Flanging can not hide the bolt hole. The edge should be chamfered or opened with scissors, and it will not crack and form arc flanging. If the four angle flanging cracking, by soldering or sealant fill, prevent wind tube leakages wind pipe plate thickness is less than 1.2mm can adopt the joint angle or stud bite, more than 1.2mm by welding.

风管成型后与法兰连接采用铆接,铆钉距风管壁距离不得大于50mm,各铆钉间距不得大于150mm。

After the pipe is formed, the rivet is connected with the flange, and the distance between the rivet distance from the wall of the wind pipe must not be more than 50mm, and the rivet spacing should not be more than 150mm.
