　　Positioning and marking should be carried out based on the layout plan of the bridge, the elevation of each floor, and the center coordinates of the bridge entering and exiting the building to ensure the accuracy of the installation position.

　　如果廠家未提供立柱及托臂成品，可根據(jù)設(shè)計(jì)要求現(xiàn)場制作或預(yù)制。制作時應(yīng)將材料矯正平直，下料誤差在允許范圍內(nèi)，切口處不應(yīng)有卷邊和毛刺。制作好的支架應(yīng)牢固、平整、尺寸準(zhǔn)確，并按設(shè)計(jì)要求涂刷防腐漆。

　　If the manufacturer does not provide finished columns and support arms, they can be made on site or prefabricated according to design requirements. During production, the material should be straightened and the cutting error should be within the allowable range. There should be no curled edges or burrs at the incision. The fabricated bracket should be firm, flat, accurately sized, and coated with anti-corrosion paint according to design requirements.

　　二、支架與吊架的安裝

　　2、 Installation of brackets and hangers

　　支架與吊架所用鋼材應(yīng)平直，無顯著扭曲。下料后長短偏差應(yīng)在允許范圍內(nèi)，切口處應(yīng)無卷邊、毛刺。

　　The steel used for brackets and hangers should be straight and free from significant distortion. After cutting, the length deviation should be within the allowable range, and there should be no curled edges or burrs at the incision.

　　鋼支架與吊架應(yīng)焊接牢固，無顯著變形。焊接前厚度超過一定標(biāo)準(zhǔn)的支架、鐵件應(yīng)打坡口，焊縫均勻平整，焊縫長度應(yīng)符合要求，不得出現(xiàn)裂紋、咬邊、氣孔、凹陷、漏焊等缺陷。

　　The steel bracket and hanger should be welded firmly without significant deformation. Brackets and iron parts with a thickness exceeding a certain standard before welding should be chamfered, and the weld seam should be uniform and flat. The length of the weld seam should meet the requirements, and there should be no defects such as cracks, undercuts, pores, depressions, or missed welds.

　　支架與吊架應(yīng)安裝牢固，保證橫平豎直。在有坡度的建筑物上安裝支架與吊架時，應(yīng)與建筑物的坡度、角度一致。

　　The bracket and hanger should be installed firmly to ensure horizontal and vertical alignment. When installing brackets and hangers on buildings with slopes, they should be consistent with the slope and angle of the building.

　　支架與吊架的規(guī)格一般不應(yīng)小于規(guī)定值，如扁鋼30mm×3mm、角鋼25mm×25mm×3mm等。嚴(yán)禁用木磚固定支架與吊架。

　　The specifications of brackets and hangers should generally not be less than the specified values, such as flat steel 30mm × 3mm, angle steel 25mm × 25mm × 3mm, etc. It is strictly prohibited to use wooden bricks to fix brackets and hangers.

　　三、橋架的安裝

　　3、 Installation of cable tray

　　橋架安裝時，應(yīng)使用專用連接片或成品構(gòu)件進(jìn)行連接，確保連接牢固可靠。直線段橋架可采用專用連接片連接，轉(zhuǎn)彎、翻彎、變徑、三通、四通處應(yīng)采用成品構(gòu)件連接。

　　When installing cable trays, specialized connecting pieces or finished components should be used for connection to ensure a firm and reliable connection. The straight section bridge can be connected with dedicated connecting pieces, and finished components should be used to connect at turns, bends, reducers, tees, and crosses.

　　橋架安裝應(yīng)牢固、橫平豎直，接地跨接可靠。電纜橋架水平安裝的支架間距為1.5~3m，垂直安裝的支架間距不大于2m。

　　The installation of cable trays should be firm, horizontal and vertical, and the grounding should be reliable. The spacing between supports for horizontal installation of cable trays is 1.5-3m, and the spacing between supports for vertical installation is not more than 2m.

　　橋架的轉(zhuǎn)彎、三通、彎頭等連接處必須采用成品配件，保證電纜小允許彎曲半徑。非鍍鋅橋架間連接板的兩端必須跨接銅芯接地線，接地線小允許截面積不小于4mm?。

　　Finished accessories must be used at the bends, tees, elbows, and other connections of the cable tray to ensure the minimum allowable bending radius of the cable. The two ends of the connecting plate between non galvanized cable trays must be bridged with copper core grounding wires, and the minimum allowable cross-sectional area of the grounding wire shall not be less than 4mm ?.

　　橋架安裝前必須核算橋架內(nèi)電纜的總截面面積與橋架截面面積的比例，確保符合要求。橋架與支架間螺栓、橋架連接板螺栓應(yīng)固定緊固無遺漏，螺母位于橋架外側(cè)。

　　Before installing the cable tray, the ratio of the total cross-sectional area of the cables inside the tray to the cross-sectional area of the tray must be calculated to ensure compliance with the requirements. The bolts between the bridge and the bracket, as well as the bolts of the bridge connecting plate, should be securely fastened without any omissions, and the nuts should be located on the outside of the bridge.

　　四、特殊環(huán)境下的安裝要求

　　4、 Installation requirements in special environments

　　在戶外或潮濕環(huán)境下安裝電纜橋架時，應(yīng)采取防腐措施，如使用復(fù)合環(huán)氧樹脂防腐阻燃型電纜橋架。

　　電纜橋架不應(yīng)作為行人通道使用。

　　Cable trays should not be used as pedestrian walkways.

　　When installing cable trays in areas prone to mechanical damage or in places with high levels of dust, protective covers should be added.

　　電纜橋架轉(zhuǎn)彎處的轉(zhuǎn)彎半徑不應(yīng)小于該橋架上電纜小允許彎曲半徑的值。

　　The turning radius at the turning point of the cable tray should not be less than the maximum allowable bending radius of the cable on the tray.

　　橋架在每個支架上的固定應(yīng)牢固，橋架內(nèi)、外連接板應(yīng)齊全，連接板的螺栓應(yīng)緊固。

　　The fixing of the bridge on each bracket should be firm, and the connecting plates inside and outside the bridge should be complete. The bolts of the connecting plates should be tightened.

　　In summary, the installation standards for cable trays cover multiple aspects, including preparation before installation, installation of brackets and hangers, installation of trays, installation requirements in special environments, and other precautions. During the installation process, these specifications and standards should be strictly followed to ensure the installation quality and safety performance of cable trays.
