　　簡述通風(fēng)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(fēng)管道和部件的裝置，土建工程應(yīng)依據(jù)風(fēng)管明裝和暗裝等狀況，有必要具備必定條件才能進(jìn)行。對明裝或在技能夾層內(nèi)裝置的風(fēng)管，應(yīng)在通風(fēng)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(jìn)行，假如通風(fēng)管道裝置后，再進(jìn)行土建及其它作業(yè)，可能會損壞通風(fēng)管道，特別是空氣潔凈體系，將會使管道內(nèi)遭到污染。對暗裝風(fēng)管的裝置，應(yīng)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(yīng)依據(jù)土建的進(jìn)展安排，派專人密切合作土建，做好孔洞的預(yù)留和預(yù)埋件的敷設(shè)作業(yè)，以免裝置時再打洞，既糟蹋工料又影響土建工程質(zhì)量。一節(jié)裝置前的準(zhǔn)備作業(yè)一、裝置前的準(zhǔn)備作業(yè)風(fēng)管體系裝置前，應(yīng)進(jìn)一步核實風(fēng)管及送回(排)風(fēng)口等部件的軸線和標(biāo)高是否與規(guī)劃圖紙相符，并查看土建預(yù)留的孔洞、預(yù)埋件的方位是否符合要求，依據(jù)施工計劃斷定的施工辦法安排勞動力出場，并將預(yù)制加工的支、吊、托架、風(fēng)管按安排好的施工次序運現(xiàn)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(zhǔn)備好，依據(jù)工程量巨細(xì)及體系的多少分段進(jìn)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(fēng)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(fēng)道支架在制作和設(shè)備時，應(yīng)注意事項：

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

　　(1)、支架制作時，應(yīng)按照國標(biāo)圖集上規(guī)矩的型鋼標(biāo)準(zhǔn)，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(fēng)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(yīng)為滿焊。

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

　　(4)、吊架中吊桿下料應(yīng)準(zhǔn)確，吊桿中心不宜出現(xiàn)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(dāng)風(fēng)道斷面較小時，風(fēng)道吊桿可選用膨脹螺栓固定在樓板上，當(dāng)風(fēng)道較大時，應(yīng)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(shè)備前，應(yīng)在墻休、柱體和樓板面上彈出風(fēng)道的中心線，然后再判定支架的水平方位及標(biāo)高，可確保設(shè)備后的風(fēng)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(shè)備前，應(yīng)對暴露部分進(jìn)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(fēng)道，為了防止產(chǎn)生冷橋，在風(fēng)管與支架的觸摸面上應(yīng)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(shè)備的支架，設(shè)備調(diào)平后，應(yīng)選用C20混凝土堵洞并搗實與結(jié)構(gòu)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(yù)理鋼構(gòu)件時，在土建澆注混凝土前，應(yīng)復(fù)核鋼構(gòu)件的方位和標(biāo)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(fēng)道支架的間隔一般為3m,但在缺少3m的風(fēng)道應(yīng)在兩端各設(shè)備一支架，在三通或彎頭處官加設(shè)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(fēng)道支架上不得設(shè)備其他的管道或線纜。

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