The material use plan shall be prepared according to the specifications and models required by the design, on-site investigation records and construction scheme, including the straight sections, elbows, bridge accessories, supports, hangers, etc. of various specifications of electric cable trays. Please note that all materials required to install the cable tray are galvanized.

根據設計要求和現場勘察記錄，編制電纜使用計劃，包括各種規格型號的電力電纜、控制電纜等

According to the design requirements and field survey records, prepare cable use plans, including power cables and control cables of various specifications and models

電纜橋架來料檢驗：

Incoming inspection of cable tray:

1）山東電纜橋架產品包裝箱內應有裝箱單、產品合格證和出廠檢驗報告，并按清單清點或附架橋架。件的大小和數量。

1) The packing box of Shandong cable tray products shall be provided with packing list, product certificate and ex factory inspection report, and the cable tray shall be counted or attached according to the list. Size and quantity of pieces.

2)檢查橋式滑輪材料的厚度應符合以下要求：

2) Check that the thickness of bridge pulley material shall meet the following requirements:

3)檢查橋架外觀，檢查外形尺寸是否與標稱型號規格一致。熱鍍鋅橋架表面應均勻，無毛刺、過燒、掛灰、傷痕，周邊不鍍鋅（直徑大于2mm）等缺陷，螺紋涂層應光滑，螺栓可旋入。當橋式螺栓直徑不大于中16直徑時，可與螺釘直徑進行比較。直徑大2mm。同組相鄰兩孔間距允許偏差為±1.2mm。

3) Check the appearance of the bridge and whether the overall dimension is consistent with the nominal model and specification. The surface of the hot-dip galvanized cable tray shall be uniform, free of burrs, overburning, ash hanging, scars, no galvanizing around (diameter greater than 2mm) and other defects. The thread coating shall be smooth, and the bolts can be screwed in. When the diameter of the bridge bolt is not greater than the diameter of the middle 16, it can be compared with the screw diameter. 2mm in diameter. The allowable deviation between two adjacent holes in the same group is ± 1.2mm.

4）檢查工作完成后，如實歸檔結果。整理后收集到的產品合格證和驗廠報告——并存文件。

4) After the inspection is completed, the results shall be truthfully filed. Product certificate and factory inspection report collected after sorting - coexisting documents.

操作流程

Operation process

標線定位根據設計圖或實施方案，從電纜橋架的起點找水平線或垂直線（先主線后支線），確定并標記支撐的確切位置。

Marking positioning according to the design drawing or implementation scheme, find the horizontal line or vertical line (main line before branch line) from the starting point of the cable tray, determine and mark the exact position of the support.

固定件金屬膨脹螺栓的安裝

Installation of metal expansion bolts of fixed parts

鉆孔深度應使套管完全嵌入墻體或頂板內，且表面齊平。

The drilling depth shall be such that the casing is completely embedded in the wall or top plate and the surface is flush.

用木錘或木塊用錘子將膨脹螺栓敲入孔內。螺栓固定后，頭部的撓度值不應大于2毫米。預埋鐵自制加工尺寸不小于120x60x60mm，在土建結構施工中應預埋預埋鐵。平面應靠近模板，并應固定牢固。

Use a wooden hammer or block to hammer the expansion bolt into the hole. After the bolt is fixed, the deflection value of the head shall not be greater than 2mm. The self-made processing size of embedded iron shall not be less than 120x60x60mm, and embedded iron shall be embedded in civil structure construction. The plane shall be close to the formwork and shall be firmly fixed.

橋梁支座的安裝：

Installation of bridge bearings:

在室內常見的山東電纜橋架安裝形式有幾種，請參考與有關橋架安裝的規則。

There are several types of cable tray installation in Shandong, please refer to the relevant tray installation rules.

自制支架、吊架用扁鐵尺寸不小于30mm×3mm，扁鋼尺寸不小于25x25×3mm。自制吊架建議按設計要求進行防腐處理。

The size of flat iron for self-made supports and hangers shall not be less than 30mm × 3mm, flat steel size not less than 25x25 × 3mm。 The self-made hangers must be subject to anti-corrosion treatment according to the design requirements.

支架和吊架在安裝時應用吊線或彈力線拉直，并用水平儀找平，確保安裝后水平垂直。

The supports and hangers shall be straightened with suspension wire or elastic line during installation, and leveled with a level to ensure that they are horizontal and vertical after installation.
