我们在山东电缆桥架施工一定会遇到很多问题，接下来给大家总结一下准备工作和施工工艺等流程。

We will certainly encounter many problems during the construction of cable tray in Shandong. Next, we will summarize the preparatory work and construction process.

一、准备工作

1、 Preparation work

1、熟悉图纸，与水暖、通风、空调各协调，确定电缆桥架安装位置及走向，以保证各的管道均能安装就位，排列布置合理，符合设计及施工规范要求；同时核算桥架及附件、配件的用量。

1. Be familiar with the drawings, coordinate with the plumbing, ventilation and air conditioning disciplines, and determine the installation position and direction of cable tray to ensure that the pipelines of all disciplines can be installed in place, arranged reasonably, and meet the requirements of design and construction specifications; Simultaneously calculate the usage of cable trays, accessories, and accessories.

2、安装电缆桥架使用的主要机具：电工工具、冲击钻、手电钻、台钻、高凳、卷尺、钢锯、线坠、粉线袋等。

2. Main machines and tools used for installing cable tray: electrician tools, impact drills, electric hand drills, bench drills, high stools, tape measures, hacksaws, wire pendants, pink wire bags, etc.

3、为方便安装施工，保证质量，各种特殊形状的弯通、非标准件一律现场实测实量，并把外形尺寸及时提供给生产厂家，由生产厂家进行工厂化加工，这样既能保证工程安装质量，同时降低了现场工人的生产劳动强度。

3. For the convenience of installation and construction, and to ensure quality, all special shaped bends and non-standard parts are measured on-site, and the external dimensions are provided to the manufacturer in a timely manner for factory processing. This not only ensures the installation quality of the project, but also reduces the production labor intensity of on-site workers.

4、桥架内外应光滑平整，无毛刺，无损伤电缆绝缘的凸起和尖角，不应有扭曲、翘边等变型现象。螺栓、垫圈、弹簧垫等配件均为镀锌件。

4. The inside and outside of the bridge should be smooth and flat, without burrs, protrusions and sharp corners that damage the cable insulation, and there should be no distortion, warping, or other deformation phenomena. Bolts, washers, spring washers, and other accessories are all galvanized parts.

5、配合土建的结构施工，检查确认预留洞、预埋铁的数量位置是否正确，有问题及时处理。

5. Cooperate with the structural construction of civil engineering, check and confirm whether the quantity and position of reserved holes and embedded iron are correct, and promptly handle any problems.

二、施工工艺

2、 Construction process

1、工艺流程

1. Process flow

弹线定位→膨胀螺栓安装→立柱、吊支架和托臂安装→电缆桥架安装→电缆桥架接地

Snap line for positioning → install expansion bolt → install column, hanger bracket and bracket → install cable tray → ground cable tray

2、弹线定位

2. Snap line positioning

根据设计图纸确定进出线、盒、箱、柜等电气器具的安装位置，从始端终端找好水平线或垂直线，用粉线袋沿墙壁、顶棚等处，沿线路的线弹线；按照设计图要求及施工验收规范规定，分匀档距，并用笔标出具体位置。

Determine the installation position of electrical appliances such as incoming and outgoing lines, boxes, boxes, cabinets, etc. according to the design drawings, and find horizontal or vertical lines from the beginning to the end. Use a pink line bag to snap lines along the wall, ceiling, etc. along the centerline of the line; According to the design drawings and construction acceptance specifications, divide the span evenly and mark the specific position with a pen.

3、水平桥架支、吊架、托臂的安装，竖直桥架的支架安装方法。

3. The installation of horizontal bridge supports, hangers, and brackets, as well as the installation method of vertical bridge supports.

（1）水平桥架（槽式）吊架安装

(1) Installation of Horizontal Bridge (Trough) Hanger

（2）水平桥架（槽式）墙、立柱支架应做成三角支撑型如下

(2) The horizontal bridge (trough type) wall and column supports should be made into triangular support types as follows

图中水平臂与竖直臂等长，焊接为满焊。靠墙或立柱侧应采用不少于两处膨胀螺栓固定。其各项参数应符合下表：

The horizontal arm and vertical arm in the figure are of equal length and are fully welded. The side against the wall or column should be fixed with at least two expansion bolts. Its various parameters should comply with the following table:

（3）竖直桥架（梯式）支架

(3) Vertical bridge (ladder type) support

各项参数应符合下列表格：

All parameters should comply with the following table:

4、水平桥架支、吊架、托臂的安装，竖直桥架的支架安装要点

4. The installation of horizontal bridge supports, hangers, and brackets, as well as the installation points of vertical bridge supports

（1）立柱、吊支架和托臂所用钢材应平直，无扭曲。下料后长短偏差应在5mm范围内，切口处应无卷边、毛刺。

(1) The steel used for columns, suspension brackets, and support arms should be straight and free from distortion. After cutting, the length deviation should be within 5mm, and there should be no curling or burrs at the incision.

（2）立柱、吊支架和托臂应安装牢固，无显著变形，焊缝均匀平整，焊缝长度应符合要求，不得出现裂纹、咬边、气孔、凹陷、漏焊、焊漏等缺陷，焊后应做好防腐处理。

(2) The columns, suspension brackets, and supporting arms should be installed firmly without significant deformation. The welds should be uniform and flat, and the length of the welds should meet the requirements. There should be no defects such as cracks, undercuts, pores, depressions, missed welds, or welding leaks. After welding, anti-corrosion treatment should be done well.

（3）立柱、吊支架和托臂的用料规格：严格按产品说明及桥架规格要求配置。
