　　简述通风管道的部件安装过程及方法

　　Brief description of installation process and method of ventilation duct parts

　　通风管道和部件的装置，土建工程应依据风管明装和暗装等状况，有必要具备必定条件才能进行。对明装或在技能夹层内装置的风管，应在通风管道装置部位的土建竣工或主体工程及地评、粉刷竣工今后进行，假如通风管道装置后，再进行土建及其它作业，可能会损坏通风管道，特别是空气洁净体系，将会使管道内遭到污染。对暗装风管的装置，应及时合作土建施工，不然将会损坏土建的装修吊顶、墙面。

　　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.

　　在施工过程中，应依据土建的进展安排，派专人密切合作土建，做好孔洞的预留和预埋件的敷设作业，以免装置时再打洞，既糟蹋工料又影响土建工程质量。一节装置前的准备作业一、装置前的准备作业风管体系装置前，应进一步核实风管及送回(排)风口等部件的轴线和标高是否与规划图纸相符，并查看土建预留的孔洞、预埋件的方位是否符合要求，依据施工计划断定的施工办法安排劳动力出场，并将预制加工的支、吊、托架、风管按安排好的施工次序运现场。同时，将施工辅佐用料(螺栓、螺母、垫料及粘接剂、密封胶等)和必要的装置东西准备好，依据工程量巨细及体系的多少分段进行装置。

　　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.

　　通风管道支架在制作和安装时的注意事项

　　Cautions in Manufacturing and Installation of Ventilation Pipe Support

　　风道支架在制作和设备时，应注意事项：

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

　　(1)、支架制作时，应按照国标图集上规矩的型钢标准，不得随意改变。

　　(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)、凡风道支架上的螺栓孔一概选用钻孔，不得选用气焊割孔。

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

　　(3)、带有斜支撑的托架，焊缝应为满焊。

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

　　(4)、吊架中吊杆下料应准确，吊杆中心不宜出现搭接焊缝。

　　(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)、当风道断面较小时，风道吊杆可选用膨胀螺栓固定在楼板上，当风道较大时，应选用钻孔因定的办法。

　　(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)、支架在设备前，应在墙休、柱体和楼板面上弹出风道的中心线，然后再判定支架的水平方位及标高，可确保设备后的风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)、支架设备前，应对暴露部分进行除锈、刷防锈漆处理。

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

　　(8)、凡低温风道，为了防止产生冷桥，在风管与支架的触摸面上应垫木方或木块。

　　(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)、墙体上设备的支架，设备调平后，应选用C20混凝土堵洞并捣实与结构面平。

　　(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)、中选用在墙、柱体上预理钢构件时，在土建浇注混凝土前，应复核钢构件的方位和标高。

　　(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)、无特殊要求时，风道支架的间隔一般为3m,但在缺少3m的风道应在两端各设备一支架，在三通或弯头处官加设支架。

　　(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)、在风道支架上不得设备其他的管道或线缆。

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