通风管道是为了使空气流通,降低有害气体浓度的一种市政基础设施。通风管,风管制作与安装所用板材、型材以及其他主要成品材料,应符合设计及相关产品现行标准的规定,并应用出厂检验合格证明,材料进场时应按现行有关标准进行验收。通风管道按材质分:一般有:钢板风管、镀锌板风管、不锈钢通风管、玻璃钢通风管、塑料通风管、复合材料通风管、彩钢夹心保温板通风管、双面铝箔保温的通风管、单面彩钢保温风管、涂胶布通风管、矿用塑料通风管等;
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 design and relevant product standards, and the factory inspection certificate shall be applied. The materials shall be accepted according to the current relevant standards when entering the site. Ventilation pipes are divided by material: generally, they are: steel plate air pipe, galvanized plate air pipe, stainless steel air pipe, FRP air pipe, plastic air pipe, composite air pipe, color steel sandwich insulation plate air pipe, double-sided aluminum foil insulation air pipe, single-sided color steel insulation air pipe, adhesive coated cloth air pipe, mining plastic air pipe, etc;
1.对于比较复杂的民用建筑,在设计阶段,各工种首先应协商好空间分隔,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。
1. For complex civil buildings, in the design stage, various types of work shall first negotiate the space separation and determine the elevation range of each kind of pipeline. Under normal circumstances, you shall not go beyond the limits set for yourself. In case of crossing the boundary of an individual pipe section, it shall negotiate with other projects.
2.解决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。
2. The principle to solve the collision and coordination of various ventilation pipes is generally as follows: "small pipe gives way to large pipe, 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 downpipe, the cold and hot water pipes shall be changed.
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,将问题解决在安装之前。
3. Before construction, the engineer of the equipment header shall draw the pipeline and single line of each type of work on a plan. Use a color pen for each pipe. Synthesize the elevation at each intersection to see if there is any contradiction, find it in time and solve the problem before installation.
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。
4. In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams.
