　　簡述通風管道的部件安裝過程及方法

　　Brief description of installation process and method of ventilation duct parts

　　通風管道和部件的裝置，土建工程應依據風管明裝和暗裝等狀況，有必要具備必定條件才能進行。對明裝或在技能夾層內裝置的風管，應在通風管道裝置部位的土建竣工或主體工程及地評、粉刷竣工今后進行，假如通風管道裝置后，再進行土建及其它作業，可能會損壞通風管道，特別是空氣潔凈體系，將會使管道內遭到污染。對暗裝風管的裝置，應及時合作土建施工，不然將會損壞土建的裝修吊頂、墻面。

　　The installation of ventilation pipes and components, civil engineering should be based on the condition of open and concealed air pipes, it is necessary to have the necessary conditions to carry out. For air ducts installed in open or in skilled sandwiches, they should be completed in the future at the site of the ventilation duct installation or the main project and the evaluation and painting. If the ventilation duct installation is followed by civil construction and other operations, the ventilation duct, especially the air cleaning system, may be damaged and the pipeline will be polluted. The installation of concealed air duct should cooperate with civil construction in time, otherwise it will damage the decoration ceiling and wall of civil construction.

　　在施工過程中，應依據土建的進展安排，派專人密切合作土建，做好孔洞的預留和預埋件的敷設作業，以免裝置時再打洞，既糟蹋工料又影響土建工程質量。一節裝置前的準備作業一、裝置前的準備作業風管體系裝置前，應進一步核實風管及送回(排)風口等部件的軸線和標高是否與規劃圖紙相符，并查看土建預留的孔洞、預埋件的方位是否符合要求，依據施工計劃斷定的施工辦法安排勞動力出場，并將預制加工的支、吊、托架、風管按安排好的施工次序運現場。同時，將施工輔佐用料(螺栓、螺母、墊料及粘接劑、密封膠等)和必要的裝置東西準備好，依據工程量巨細及體系的多少分段進行裝置。

　　In the process of construction, according to the progress of civil engineering, special personnel should be sent to work closely with civil engineering, do well in the preparation of holes and the laying of embedded parts, so as not to drill holes again when installing, which will not only waste materials but also affect the quality of civil engineering. Section 1 Preparatory operation before installation. Before air duct system installation for preparation operation before installation, it is necessary to further verify whether the axis and elevation of air duct and return (exhaust) air outlet and other components are in conformity with the planning drawings, check whether the orientation of the reserved holes and embedded parts in civil engineering meets the requirements, arrange labor exit according to the construction method determined by the construction plan, and expenditure on prefabricated processing. The suspension, bracket and air duct are transported to the site in the arranged construction sequence. At the same time, the construction auxiliary materials (bolts, nuts, cushions, adhesives, sealants, etc.) and necessary equipment are prepared, and the equipment is carried out according to the size of the project and the number of segments of the system.

　　通風管道支架在制作和安裝時的注意事項

　　Cautions in Manufacturing and Installation of Ventilation Pipe Support

　　風道支架在制作和設備時，應注意事項：

　　Attentions should be paid to the construction and equipment of air duct support:

　　(1)、支架制作時，應按照國標圖集上規矩的型鋼標準，不得隨意改變。

　　(1) When making the bracket, it shall conform to the section steel standard stipulated in the national standard atlas and shall not be changed at will.

　　(2)、凡風道支架上的螺栓孔一概選用鉆孔，不得選用氣焊割孔。

　　(2) All bolt holes on air duct brackets shall be drilled, and gas welding cutting shall not be used.

　　(3)、帶有斜支撐的托架，焊縫應為滿焊。

　　(3) The bracket with oblique support shall be fully welded.

　　(4)、吊架中吊桿下料應準確，吊桿中心不宜出現搭接焊縫。

　　(4) The suspender should be cut out accurately in the suspension frame, and the overlap weld should not appear in the center of the suspender.

　　(5)、當風道斷面較小時，風道吊桿可選用膨脹螺栓固定在樓板上，當風道較大時，應選用鉆孔因定的辦法。

　　(5) When the cross-section of the duct is small, expansion bolts can be used to fix the hangers on the floor. When the duct is large, the drilling method should be selected.

　　(6)、支架在設備前，應在墻休、柱體和樓板面上彈出風道的中心線，然后再判定支架的水平方位及標高，可確保設備后的風道的水平度和平面中心方位。

　　(6) Before the bracket is installed, the central line of the air duct should be ejected from the wall rest, column and floor surface, and then the horizontal orientation and elevation of the bracket can be determined to ensure the horizontal and horizontal central orientation of the air duct behind the equipment.

　　(7)、支架設備前，應對暴露部分進行除銹、刷防銹漆處理。

　　(7) Before the bracket equipment, the exposed part should be rusted and brushed with anti-rust paint.

　　(8)、凡低溫風道，為了防止產生冷橋，在風管與支架的觸摸面上應墊木方或木塊。

　　(8) In order to prevent cold bridges from occurring in low-temperature air ducts, wooden blocks should be padded on the contact surface between the ducts and the brackets.

　　(9)、墻體上設備的支架，設備調平后，應選用C20混凝土堵洞并搗實與結構面平。

　　(9) After leveling the bracket of the equipment on the wall, C20 concrete should be selected to plug the hole and tamper with the structural plane.

　　(10)、中選用在墻、柱體上預理鋼構件時，在土建澆注混凝土前，應復核鋼構件的方位和標高。

　　(10) When prefabricating steel members on walls and columns is selected, the orientation and elevation of steel members should be checked before concrete is poured into civil construction.

　　(11)、無特殊要求時，風道支架的間隔一般為3m,但在缺少3m的風道應在兩端各設備一支架，在三通或彎頭處官加設支架。

　　(11) When there is no special requirement, the air duct bracket is generally 3 m apart, but in the absence of 3 m air duct should be equipped with a bracket at both ends, and brackets should be installed at tees or elbows.

　　(12)、在風道支架上不得設備其他的管道或線纜。

　　(12) No other professional pipeline or cable shall be equipped on the duct bracket.
