　　通風(fēng)管道支架在制作和安裝時(shí)的注意事項(xiàng)

　　Cautions in Manufacturing and Installation of Ventilation Pipe Support

　　風(fēng)道支架在制作和設(shè)備時(shí)，應(yīng)注意事項(xiàng)：

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

　　(1)、支架制作時(shí)，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(shí)，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(shí)，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(shí)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(shí)，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(shí)，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.
