        關于通風管道施工前贏做好哪些準備?

        通風管道是為了使空氣流通,降低有害氣體濃度的一種市政基礎設施。通風管,風管制作與安裝所用板材、型材以及其他主要成品材料,應符合設計及相關產品國家現行標準的規定,并應用出廠檢驗合格證明,材料進場時應按國家現行有關標準進行驗收。
        Ventilation duct is a municipal infrastructure to circulate air and reduce the concentration of harmful gases. The plates, profiles and other main finished materials used for the fabrication and installation of ventilation pipes and air ducts shall comply with the provisions of the current national standards for design and related products, and the factory inspection certificate shall be applied. The materials shall be accepted according to the current national standards when entering the site.
        通風管道按材質分:一般有:鋼板風管(普通鋼板)、通風管道、不銹鋼通風管、玻璃鋼通風管、料通風管、復合材料通風管、彩鋼夾心保溫板通風管、雙面鋁箔保溫通風管、單面彩鋼保溫風管、涂膠布通風管(如礦用風筒)、礦用塑料通風管等。
        Ventilation ducts are divided by material: generally, they are: steel plate air duct (ordinary steel plate), ventilation duct, stainless steel air duct, FRP air duct, material air duct, composite air duct, color steel sandwich insulation board air duct, double-sided aluminum foil insulation air duct, single-sided color steel insulation air duct, adhesive coated air duct (such as mine air duct), mine plastic air duct, etc.
        預制好的風管,需要做好存放工作,以免受到二次污染。可將管口用塑料布等密封材料封住,然后將風管分門別類堆放好。使用管道前,請注意清洗作業,確認板材表面沒有腐蝕,干燥后不進行清掃。
        The prefabricated air duct needs to be stored to avoid secondary pollution. The pipe orifice can be sealed with sealing materials such as plastic cloth, and then the air ducts can be stacked by categories. Before using the pipeline, please pay attention to the cleaning operation, confirm that the plate surface is free of corrosion, and do not clean it after drying.
        1、施工前的準備工作
        1. Preparation before construction
        俗話說,“磨刀不誤砍柴”,充分的說明準備是保證風管安裝質量的前提。準備清潔管道的制作,無論采用工廠集中制作還是現場制作方式,都要保證場所的清潔和關閉,具有符合條件的采光和照明條件。另外,還要對制作好的方管進行看管,盡量避免污染。
        As the saying goes, "sharpen your knife without mistaking firewood", it fully shows that preparation is the premise to ensure the installation quality of air duct. Prepare the fabrication of clean pipes, whether centralized fabrication in the factory or on-site fabrication, ensure that the site is clean and closed, and have qualified daylighting and lighting conditions. In addition, we should take care of the prepared square tube to avoid pollution as far as possible.
        2、風管材質的選擇
        2. Selection of duct material
        選擇對管道的施工質量也有很大影響。一般來說,為了保證管道的重量,需要較小板厚的管道,但需要綜合考慮管道的尺寸和壓力水平。從設計角度來看,值得注意的是,一個系統可以同時具有對應于不同靜態壓力水平的幾個管道厚度。
        The selection also has a great impact on the construction quality of the pipeline. Generally speaking, in order to ensure the weight of the pipeline, the pipeline with smaller plate thickness is required, but the size and pressure level of the pipeline need to be comprehensively considered. From a design point of view, it is worth noting that a system can have several pipe thicknesses corresponding to different static pressure levels at the same time.
        3、風管的橫向連接
        3. Transverse connection of air duct
        風管的橫向連接有一定的應力。這種連接方法可以說是延長空氣導管長度的手段,并且還具有增強剛性和保持空氣導管橫向尺寸的功能通常,橫向連接方式是角鋼法蘭連接。這種連接模式取決于壁厚,也取決于連接類型和板墻加固模式。
        The transverse connection of air duct has certain stress. This connection method can be said to be a means to extend the length of the air duct, and also has the function of enhancing the rigidity and maintaining the transverse size of the air duct. Generally, the transverse connection method is angle steel flange connection. This connection mode depends on the wall thickness, the connection type and the plate wall reinforcement mode.
