結(jié)合實(shí)際情況進(jìn)行檢查復(fù)核，再按編號(hào)進(jìn)行排列，風(fēng)管系統(tǒng)的各部分尺寸和角度確確無(wú)誤后，即開始風(fēng)管組對(duì)工作。風(fēng)管各管段之間的連接采用法蘭連接，接口處要求嚴(yán)密不漏風(fēng)。一次吊裝風(fēng)管的長(zhǎng)度要根據(jù)建筑物的條件，風(fēng)管的壁厚，吊裝方法和吊裝機(jī)具配備情況確定，組對(duì)好的風(fēng)管可把兩端的法蘭做為基準(zhǔn)點(diǎn)，以中間法蘭為測(cè)點(diǎn)，拉線測(cè)量風(fēng)管的連接是否平直，偏差大時(shí)要進(jìn)行調(diào)整

Based on the actual situation, conduct inspection and review, and then arrange according to the number. Once the dimensions and angles of each part of the air duct system are confirmed to be correct, the air duct assembly work begins. The connection between each section of the air duct adopts flange connection, and the interface must be tight and air tight. The length of the air duct to be lifted at a time should be determined based on the conditions of the building, the wall thickness of the air duct, the lifting method, and the allocation of lifting equipment. The assembled air duct can use the flanges at both ends as reference points, and the middle flange as the measuring point. Pull a line to measure whether the connection of the air duct is straight, and adjust it when there is a large deviation

薄鋼板通風(fēng)管道制造裝置項(xiàng)目中，包含彎頭三通變徑管天圓地方等管件及法蘭加固框和吊托支架的制造用工但不包含過(guò)跨風(fēng)管落地支架，落地支架履行設(shè)備支架項(xiàng)目。煙道過(guò)于狹窄，大排量煙機(jī)一般每分鐘排風(fēng)量會(huì)在13立方米左右，過(guò)于狹小的煙道會(huì)造成排風(fēng)受阻，氣流回轉(zhuǎn)，風(fēng)壓加大產(chǎn)生的噪音，還有就是要檢查一下看看排煙管是否深入煙道過(guò)多，在墻壁或天花板上砌上消音磚，或涂上消音漆以及安裝隔音門等。

In the manufacturing equipment project of thin steel plate ventilation ducts, it includes the manufacturing labor for pipe fittings such as elbows, tees, and variable diameter pipes, as well as flange reinforcement frames and suspension brackets. However, it does not include the cross span air duct floor bracket, which fulfills the equipment support project. The flue is too narrow, and the exhaust air volume of a large displacement fan is generally around 13 cubic meters per minute. A narrow flue can cause obstruction of the exhaust air, rotation of the airflow, and noise generated by increased air pressure. Additionally, it is necessary to check whether the exhaust pipe penetrates too deeply into the flue, lay soundproof bricks on the wall or ceiling, apply soundproof paint, and install soundproof doors.
