施工現(xiàn)場(chǎng)電纜橋架大致分為主橋架和分支架。主橋架是由設(shè)計(jì)院設(shè)計(jì)，根據(jù)圖紙施工；分支架是由主橋架引到就地設(shè)備的電纜支架，沒有圖紙?jiān)O(shè)計(jì)，根據(jù)現(xiàn)場(chǎng)情況由施工人員來設(shè)計(jì)的。常用的彎頭種類包括：上下跳彎45°、垂直上下彎頭、水平三通等。下面山東電纜橋架廠家來講講橋架45°上下爬坡彎的有關(guān)制作內(nèi)容：

The cable bridge at the construction site is roughly divided into main bridge frame and sub-frame. The main bridge frame is designed by the design institute and constructed according to the drawings; The sub-support is the cable support led from the main bridge to the local equipment. There is no drawing design, and it is designed by the construction personnel according to the site conditions. The commonly used elbow types include: jumping up and down 45 °, vertical up and down elbow, horizontal tee, etc. Next, Shandong cable bridge manufacturer will talk about the relevant manufacturing content of 45 ° up-and-down ramp of the bridge:

1.自制的電纜橋架彎頭、跳彎、三通的連接處，應(yīng)先在內(nèi)側(cè)進(jìn)行點(diǎn)焊固定并把毛刺藥皮打磨干凈，外側(cè)應(yīng)平整，縫隙應(yīng)盡量小且鋸口處平整整齊。

1. For the connection of self-made cable tray elbow, jump bend and tee, spot welding shall be carried out on the inner side first and the burr coating shall be polished. The outer side shall be flat, the gap shall be as small as possible and the saw mouth shall be flat and tidy.

2.電纜橋架彎頭對(duì)接無錯(cuò)邊，焊接后的對(duì)口處應(yīng)打磨平整、光潔，不應(yīng)有損傷電纜絕緣層的毛刺、銳邊等棱角。

2. The butt joint of the cable tray elbow shall be free of misalignment, and the butt joint after welding shall be polished and smooth, and there shall be no burrs, sharp edges and other edges that damage the cable insulation layer.

3.在托盤式電纜橋架內(nèi)加鋼筋時(shí)，采用增加Φ6-8MM圓鋼，內(nèi)、外側(cè)都應(yīng)補(bǔ)刷油漆。刷油漆前，應(yīng)把藥皮，焊渣清理干凈。

3. When adding reinforcement in the tray type cable tray, add Φ The inner and outer sides of 6-8MM round steel shall be repainted. Before painting, the coating and welding slag shall be cleaned.

4.多層電纜橋架的自制三通及彎頭安裝完成后，折角應(yīng)在垂直的統(tǒng)一直線上。

4. After the installation of the self-made tee and elbow of the multi-layer cable bridge, the bending angle should be in the vertical uniform straight line.

5.所有自制彎頭制作完成后，應(yīng)在切割、打磨、焊接處刷防銹漆，再刷與橋架顏色相同面漆。

5. After the fabrication of all self-made elbows, anti-rust paint shall be applied at the cutting, grinding and welding positions, and then the finish paint with the same color as the bridge.

目前電建施工中所使用的電纜橋架彎頭一般是由電纜橋架廠在出廠之前完整加工好的，但是由于施工現(xiàn)場(chǎng)情況各不相同，所以有的項(xiàng)目需要因地制宜現(xiàn)場(chǎng)加工電纜橋架彎頭，這就需要安裝人員有一定的施工基礎(chǔ)知識(shí)才能勝任。有關(guān)于電纜橋架的信息了解，就來我們網(wǎng)站http://m.ymmgjx.net咨詢吧！

At present, the cable bridge elbow used in power construction is generally completely processed by the cable bridge factory before leaving the factory. However, due to the different construction site conditions, some projects need to process the cable bridge elbow according to local conditions, which requires the installation personnel to have certain basic construction knowledge to be competent.
