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(zhǔn)備工作

1、 Preparation work

1、熟悉圖紙，與水暖、通風(fēng)、空調(diào)各協(xié)調(diào)，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(shè)計(jì)及施工規(guī)范要求；同時(shí)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(jī)具：電工工具、沖擊鉆、手電鉆、臺(tái)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(zhì)量，各種特殊形狀的彎通、非標(biāo)準(zhǔn)件一律現(xiàn)場(chǎng)實(shí)測(cè)實(shí)量，并把外形尺寸及時(shí)提供給生產(chǎn)廠家，由生產(chǎn)廠家進(jìn)行工廠化加工，這樣既能保證工程安裝質(zhì)量，同時(shí)降低了現(xiàn)場(chǎng)工人的生產(chǎn)勞動(dòng)強(qiáng)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(nèi)外應(yīng)光滑平整，無毛刺，無損傷電纜絕緣的凸起和尖角，不應(yīng)有扭曲、翹邊等變型現(xiàn)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(jié)構(gòu)施工，檢查確認(rèn)預(yù)留洞、預(yù)埋鐵的數(shù)量位置是否正確，有問題及時(shí)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(jù)設(shè)計(jì)圖紙確定進(jìn)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(shè)計(jì)圖要求及施工驗(yàn)收規(guī)范規(guī)定，分勻檔距，并用筆標(biāo)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。
