电缆桥架来料检验：

Incoming inspection of cable tray:

1）山东电缆桥架产品包装箱内应有装箱单、产品合格证和出厂检验报告，并按清单清点或附架桥架。件的大小和数量。

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)检查桥式滑轮材料的厚度应符合以下要求：

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

3)检查桥架外观，检查外形尺寸是否与标称型号规格一致。热镀锌桥架表面应均匀，无毛刺、过烧、挂灰、伤痕，周边不镀锌（直径大于2mm）等缺陷，螺纹涂层应光滑，螺栓可旋入。当桥式螺栓直径不大于中16直径时，可与螺钉直径进行比较。直径大2mm。同组相邻两孔间距允许偏差为±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）检查工作完成后，如实归档结果。整理后收集到的产品合格证和验厂报告——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

标线定位根据设计图或实施方案，从电缆桥架的起点找水平线或垂直线（先主线后支线），确定并标记支撑的确切位置。

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.

固定件金属膨胀螺栓的安装

Installation of metal expansion bolts of fixed parts

钻孔深度应使套管完全嵌入墙体或顶板内，且表面齐平。

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

用木锤或木块用锤子将膨胀螺栓敲入孔内。螺栓固定后，头部的挠度值不应大于2毫米。预埋铁自制加工尺寸不小于120x60x60mm，在土建结构施工中应预埋预埋铁。平面应靠近模板，并应固定牢固。

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.

桥梁支座的安装：

Installation of bridge bearings:

在室内常见的 山东电缆桥架安装形式有几种，请参考与有关桥架安装的规则。

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

自制支架、吊架用扁铁尺寸不小于30mm×3mm，扁钢尺寸不小于25x25×3mm。自制吊架必须按设计要求进行防腐处理。

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.

支架和吊架在安装时应用吊线或弹力线拉直，并用水平仪找平，确保安装后水平垂直。

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.
