通风管道支架的安装注意事项！
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.
