通風管道的優(yōu)勢

Advantages of Ventilation Pipeline

1）通風管道防火性能好：當前普遍存在的問題是成品通風道燃燒性能和耐火極限未經有關部門檢測，且部分通風道材料的燃燒性能）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）造價低：通風管道與傳統(tǒng)磚砌通風道比，能節(jié)約工程造價40%左右；

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

3）輕質高強：與傳統(tǒng)磚砌通風道比，菱鎂通風道自重輕）強度高，能大幅度降低建筑物的承受荷載；

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）設計靈活：通風管道可根據預留洞的大小，隨時調整管道的規(guī)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）設計獨特：通風管道的開口上安裝了煙氣止回閥和防火隔離門，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）通風管道施工簡單： 增加了室內空間，密閉性好）不返煙）不返臭，能大幅度改善室內環(huán)境。

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

施工注意事項

Matters needing attention in construction

1）對于比較復雜的民用建筑，通風管道在設計階段，各工種（暖通）給水排水，供電照明與建筑）應協商好空間分隔，定出每種管道的標高范圍。一般情況下不得越出給自己規(guī)定的界限。遇有個別管段要越界時應與其他工程協商。

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）解決各種通風管道相碰及協調的原則，一般為：“小管讓大管，有壓讓無壓”。例如，自來水管與風管相撞，則應當自來水管拐彎。冷）熱水管與下水管相碰，則應改變冷）熱水管道。

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）施工前應設備總管的工程師，將各工種的管線，單線畫在一張平面圖上。每種管道用一種彩色筆。在各交點處綜合其標高，看是否有矛盾之處，及時發(fā)現，將問題解決在安裝之前。

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）為了減少投資，節(jié)省空間，降低層高，有些敷設無坡度要求的通風管道，可以穿梁敷設（如自來水管道，消防噴灑干管等）。

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.).
