我們在山東電纜橋架施工一定會遇到很多問題，接下來給大家總結一下準備工作和施工工藝等流程。

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、準備工作

1、 Preparation work

1、熟悉圖紙，與水暖、通風、空調各協調，確定電纜橋架安裝位置及走向，以保證各的管道均能安裝就位，排列布置合理，符合設計及施工規范要求；同時核算橋架及附件、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、安裝電纜橋架使用的主要機具：電工工具、沖擊鉆、手電鉆、臺鉆、高凳、卷尺、鋼鋸、線墜、粉線袋等。

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、為方便安裝施工，保證質量，各種特殊形狀的彎通、非標準件一律現場實測實量，并把外形尺寸及時提供給生產廠家，由生產廠家進行工廠化加工，這樣既能保證工程安裝質量，同時降低了現場工人的生產勞動強度。

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、橋架內外應光滑平整，無毛刺，無損傷電纜絕緣的凸起和尖角，不應有扭曲、翹邊等變型現象。螺栓、墊圈、彈簧墊等配件均為鍍鋅件。

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、配合土建的結構施工，檢查確認預留洞、預埋鐵的數量位置是否正確，有問題及時處理。

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、施工工藝

2、 Construction process

1、工藝流程

1. Process flow

彈線定位→膨脹螺栓安裝→立柱、吊支架和托臂安裝→電纜橋架安裝→電纜橋架接地

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

2、彈線定位

2. Snap line positioning

根據設計圖紙確定進出線、盒、箱、柜等電氣器具的安裝位置，從始端終端找好水平線或垂直線，用粉線袋沿墻壁、頂棚等處，沿線路的線彈線；按照設計圖要求及施工驗收規范規定，分勻檔距，并用筆標出具體位置。

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、水平橋架支、吊架、托臂的安裝，豎直橋架的支架安裝方法。

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

（1）水平橋架（槽式）吊架安裝

(1) Installation of Horizontal Bridge (Trough) Hanger

（2）水平橋架（槽式）墻、立柱支架應做成三角支撐型如下

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

圖中水平臂與豎直臂等長，焊接為滿焊。靠墻或立柱側應采用不少于兩處膨脹螺栓固定。其各項參數應符合下表：

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）豎直橋架（梯式）支架

(3) Vertical bridge (ladder type) support

各項參數應符合下列表格：

All parameters should comply with the following table:

4、水平橋架支、吊架、托臂的安裝，豎直橋架的支架安裝要點

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

（1）立柱、吊支架和托臂所用鋼材應平直，無扭曲。下料后長短偏差應在5mm范圍內，切口處應無卷邊、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、吊支架和托臂應安裝牢固，無顯著變形，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、焊漏等缺陷，焊后應做好防腐處理。

(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.
