電纜橋架的安裝規范標準涵蓋多個方面，以下是詳細的規范標準：

　　The installation specifications and standards for cable trays cover multiple aspects, and the following are detailed specifications and standards:

　　一、安裝前的準備

　　1、 Preparation before installation

　　應根據橋架的平面布置圖、各層標高及橋架進出建筑物的中心坐標進行定位劃線，確保安裝位置的準確性。

　　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，可根據設計要求現場制作或預制。制作時應將材料矯正平直，下料誤差在允許范圍內，切口處不應有卷邊和毛刺。制作好的支架應牢固、平整、尺寸準確，并按設計要求涂刷防腐漆。

　　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平直，無顯著扭曲。下料后長短偏差應在允許范圍內，切口處應無卷邊、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.

　　鋼支架與吊架應焊接牢固，無顯著變形。焊接前厚度超過一定標準的支架、鐵件應打坡口，焊縫均勻平整，焊縫長度應符合要求，不得出現裂紋、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.

　　支架與吊架的規格一般不應小于規定值，如扁鋼30mm×3mm、角鋼25mm×25mm×3mm等。嚴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，應使用專用連接片或成品構件進行連接，確保連接牢固可靠。直線段橋架可采用專用連接片連接，轉彎、翻彎、變徑、三通、四通處應采用成品構件連接。

　　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、橋架連接板螺栓應固定緊固無遺漏，螺母位于橋架外側。

　　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、特殊環境下的安裝要求

　　4、 Installation requirements in special environments

　　在戶外或潮濕環境下安裝電纜橋架時，應采取防腐措施，如使用復合環氧樹脂防腐阻燃型電纜橋架。

　　When installing cable trays outdoors or in humid environments, anti-corrosion measures should be taken, such as using composite epoxy resin anti-corrosion and flame-retardant cable trays.

　　在有爆炸危險的場所安裝電纜橋架時，應符合爆炸和火災危險環境電力裝置設計規范的要求。

　　When installing cable trays in places with explosion hazards, they should comply with the requirements of the design specifications for electrical installations in explosive and fire hazardous environments.

　　電纜橋架穿越防火分區時，應在穿越處設置防火封堵。

　　When cable trays pass through fire compartments, fireproof sealing should be installed at the crossing points.

　　五、其他注意事項

　　5、 Other precautions

　　電纜橋架的安裝及設計還應符合現行有關標準以及規范的規定。

　　The installation and design of cable trays should also comply with the current relevant national standards and specifications.

　　電纜橋架不應作為行人通道使用。

　　Cable trays should not be used as pedestrian walkways.

　　在容易受到機械損傷的處所或粉塵較多的場所安裝電纜橋架時，應加保護罩。

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

　　電纜橋架轉彎處的轉彎半徑不應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牢固，橋架內、外連接板應齊全，連接板的螺栓應緊固。

　　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.

　　綜上所述，電纜橋架的安裝規范標準涵蓋了多個方面，包括安裝前的準備、支架與吊架的安裝、橋架的安裝、特殊環境下的安裝要求以及其他注意事項等。在安裝過程中，應嚴格遵守這些規范標準，確保電纜橋架的安裝質量和性能。

　　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.
