通風(fēng)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(chǔ)設(shè)施。通風(fēng)管，風(fēng)管制作與安裝所用板材、型材以及其他主要成品材料，應(yīng)符合設(shè)計(jì)及相關(guān)產(chǎn)品現(xiàn)行標(biāo)準(zhǔn)的規(guī)定，并應(yīng)用出廠(chǎng)檢驗(yàn)合格證明，材料進(jìn)場(chǎng)時(shí)應(yīng)按現(xiàn)行有關(guān)標(biāo)準(zhǔn)進(jìn)行驗(yàn)收。通風(fēng)管道按材質(zhì)分：一般有：鋼板風(fēng)管、鍍鋅板風(fēng)管、不銹鋼通風(fēng)管、玻璃鋼通風(fēng)管、塑料通風(fēng)管、復(fù)合材料通風(fēng)管、彩鋼夾心保溫板通風(fēng)管、雙面鋁箔保溫的通風(fēng)管、單面彩鋼保溫風(fēng)管、涂膠布通風(fēng)管、礦用塑料通風(fēng)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.對(duì)于比較復(fù)雜的民用建筑，在設(shè)計(jì)階段，各工種首先應(yīng)協(xié)商好空間分隔，定出每種管道的標(biāo)高范圍。一般情況下不得越出給自己規(guī)定的界限。遇有個(gè)別管段要越界時(shí)應(yīng)與其他工程協(xié)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.解決各種通風(fēng)管道相碰及協(xié)調(diào)的原則，一般為：“小管讓大管，有壓讓無(wú)壓”。例如，自來(lái)水管與風(fēng)管相撞，則應(yīng)當(dāng)自來(lái)水管拐彎。冷、熱水管與下水管相碰，則應(yīng)改變冷、熱水管道。
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.施工前應(yīng)設(shè)備總管的工程師，將各工種的管線(xiàn)，單線(xiàn)畫(huà)在一張平面圖上。每種管道用一種彩色筆。在各交點(diǎn)處綜合其標(biāo)高，看是否有矛盾之處，及時(shí)發(fā)現(xiàn)，將問(wèn)題解決在安裝之前。
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.為了減少投資，節(jié)省空間，降低層高，有些敷設(shè)無(wú)坡度要求的管道，可以穿梁敷設(shè)。
4. In order to reduce investment, save space and reduce floor height, some pipes without slope requirements can be laid through beams.
