通风管道的优势

Advantages of Ventilation Pipeline

1)通风管道防火性能好:当前普遍存在的问题是成品通风道燃烧性能和耐火极限未经国家有关部门检测,且部分通风道材料的燃烧性能)管壁厚度不符合要求。

1) Fire-proof performance of ventilation duct is good: At present, the common problem is that the combustion performance and fire-resistant limit of finished ventilation duct have not been tested by relevant state departments, and the combustion performance of some materials of ventilation duct) wall thickness does not meet the requirements。

2)造价低:通风管道与传统砖砌通风道比,能节约工程造价40%左右;

2) Low cost: ventilation duct can save about 40% of project cost compared with traditional brick ventilation duct;

3)轻质高强:与传统砖砌通风道比,菱镁通风道自重轻)强度高,能大幅度降低建筑物的承受荷载;

3) Light weight and high strength: Compared with the traditional brick ventilation duct, magnesite ventilation duct has higher self-weight and high strength, which can greatly reduce the bearing load of buildings.

4)设计灵活:通风管道可根据预留洞的大小,随时调整管道的规格尺寸;

4) Flexible design: ventilation pipe can adjust the size of the pipe at any time according to the size of the reserved hole;

5)设计独特:通风管道的开口上安装了烟气止回阀和防火隔离门,可以有效防止串味和串火;

5) Unique design: flue gas check valve and fire isolation door are installed on the opening of ventilation pipeline, which can effectively prevent cross-odor and crossfire.

6)通风管道施工简单: 增加了室内空间,密闭性好)不返烟)不返臭,能大幅度改善室内环境。

6) Ventilation pipeline construction is simple: increased indoor space, good airtightness), no smoke return, no odor return, can greatly improve the indoor environment。

施工注意事项

Matters needing attention in construction

1)对于比较复杂的民用建筑,通风管道在设计阶段,各工种(暖通)给水排水,供电照明与建筑专业)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 more complex civil buildings, ventilation pipelines in the design stage, various types of work (HVAC) water supply and drainage, power supply and lighting and construction profession) should first negotiate a good space separation, determine the elevation range of each pipeline。 Normally, it is not allowed to go beyond the limits set for itself。 Consultation with other projects should be conducted when there is an individual pipeline crossing the boundary。

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 of solving the collision and coordination of various ventilation pipes is generally as follows: "Small pipes let big pipes, pressure let no pressure"。 For example, when a water pipe collides with an air pipe, the water pipe should turn。 If the hot water pipe collides with the sewer pipe, the cold hot water pipe should 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 the construction, the Engineer in charge of the equipment shall draw the pipelines of each type of work on a single plan。 Each pipe uses a colour pen。 Integrate the elevation at each intersection to see if there are any contradictions, find out 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通风管道,可以穿梁敷设(如自来水管道,消防喷洒干管等)。

4) In order to reduce investment, save space and reduce floor height, some ventilation pipes without gradient requirements can be laid through beams (such as tap water pipes, fire spraying trunk pipes, etc.).
