通风管道风管施工

Air duct construction

1）对于比较复杂的民用建筑，在设计阶段，各工种（暖通、给水排水，供电照明与建筑）应协商好空间分隔，定出每种管道的标高范围。一般情况下不得越出给自己规定的界限。遇有个别管段要越界时应与其他工程协商。2）各种通风管道相碰及协调的原则，一般为：“小管让大管，有压让无压”。例如，自来水管与风管相撞，则应当自来水管拐弯。冷、热水管与下水管相碰，则应改变冷、热水管道。3）施工前应设备总管的工程师，将各工种的管线，单线画在一张平面图上。每种管道用一种彩色笔。在各交点处综合其标高，看是否有矛盾之处，及时发现，将问题在安装之前。4）为了减少投资，节省空间，降低层高，有些敷设无坡度要求的管道，可以穿梁敷设（如自来水管道，消防喷洒干管等）。

1) For more complex civil buildings, in the design phase, all types of work (HVAC, water supply and drainage, power supply and lighting and architecture) should first negotiate space separation and determine the elevation range of each type of pipe. In general, you should not exceed the limits set for yourself. In case of pipeline section crossing the boundary, it shall negotiate with other projects. 2) The principle to solve the collision and coordination of various ventilation pipes is generally: "small pipes give way to large ones, and pressure gives way to no pressure". For example, if the water pipe collides with the air pipe, the water pipe should turn. If the cold and hot water pipes collide with the sewer pipe, the cold and hot water pipes shall be changed. 3) Before construction, the engineer in charge of equipment shall draw the pipelines and single lines of each type of work on a plan. One color pen for each type of pipe. The elevation of each intersection shall be integrated to see if there is any contradiction, and the problem shall be solved before installation. 4) In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams (such as water supply pipes, fire sprinkler main pipes, etc.).

通风管道无机玻璃钢

Inorganic glass fiber reinforced plastic for ventilation duct

无机玻璃钢通风管（又称玻璃纤维氯氧镁水泥通风管）是以氯氧镁水泥为胶结料中碱玻璃纤维为增强材料、加入填充材料和改性剂等所制成的一种管材。它具有不燃烧、属不燃材料A级，耐腐蚀、强度高和重量轻等特点。在建筑工程、地下工程及工业厂房的通风中，它已经完全取代了不耐燃的有机玻璃钢通风管，并在逐步取代防腐性能差的镀锌铁皮通风管。尤其是在湿度大的地下工程和长江以南地区，它的优越性更为显著。通过氯氧镁胶凝材料的研究及制品的检测，发现无机玻璃钢通风管在生产中及工程应用中仍存在一些质量问题。有的质量问题严重影响了工程的使用寿命，应引起大家足够重视。

Inorganic glass fiber reinforced plastic ventilation pipe (also known as glass fiber magnesium oxychloride cement ventilation pipe) is a pipe made of magnesium oxychloride cement as the binder, alkali glass fiber as the reinforcement, filler materials and modifiers. It has the characteristics of incombustible, Class A incombustible material, corrosion resistance, high strength and light weight. In the ventilation of construction projects, underground projects and industrial plants, it has completely replaced the non flame resistant PMMA ventilation pipe, and gradually replaced the galvanized iron ventilation pipe with poor anti-corrosion performance. Especially in the underground projects with high humidity and the areas south of the Yangtze River, its advantages are more significant. Through the research of magnesium oxychloride cementitious materials and the detection of products, it is found that there are still some quality problems in the production and engineering application of inorganic FRP ventilation pipes. Some quality problems seriously affect the service life of the project, which should be paid enough attention to.
