　　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.
