電纜橋架彎頭45上下爬坡彎制作要注意什么
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)場情況各不相同，所以有的項目需要因地制宜現(xiàn)場加工電纜橋架彎頭，這就需要安裝人員有一定的施工基礎(chǔ)知識才能勝任。 施工現(xiàn)場電纜橋架大致分為主橋架和分支架。主橋架是由設(shè)計院設(shè)計，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，沒有圖紙設(shè)計，根據(jù)現(xiàn)場情況由施工人員來設(shè)計的。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。
At present, the cable bridge elbow used in power construction is generally processed by the cable bridge factory before leaving the factory. However, due to the different conditions on the construction site, some projects need to process the cable bridge elbow according to local conditions, which requires the installation personnel to have some basic knowledge of construction to be competent. The cable bridge in construction site can be roughly divided into main bridge and bracket. The main bridge frame is designed by the design institute and constructed according to the drawings; the branch frame is the cable bracket which is led from the main bridge frame to the local equipment, without drawings, and is designed by the constructors according to the site conditions. Commonly used elbow types include: up and down jump 45 degrees, vertical up and down elbow, horizontal tee, etc.
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)進行點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. The joint of elbow, jump and tee of self-made cable bridge frame should be fixed by spot welding on the inner side and polished with burr coating. The outer side should be smooth, and the gap should be as small as possible and the saw edge should be smooth and neat.
2.電纜橋架彎頭對接無錯邊，焊接后的對口處應(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. There are no wrong edges in the butt joint of cable bridge elbow. The butt joint after welding should be smooth and smooth, and there should be no burrs or sharp edges that damage the insulation layer of cable.
3.在托盤式電纜橋架內(nèi)加鋼筋時，采用增加Φ6-8MM圓鋼，內(nèi)、外側(cè)都應(yīng)補刷油漆。刷油漆前，應(yīng)把藥皮，焊渣清理干凈。
3. When adding reinforcing bars to tray-type cable bridge, add 6-8MM round steel, and paint should be repaired both inside and outside. Before painting, the coating and welding slag should be cleaned up.
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 tees and elbows of the multi-layer cable bridge frame is completed, the bending angle should be on 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 making all self-made elbows, the rust-proof paint should be brushed at the cutting, polishing and welding points, and then the top paint with the same color as the bridge frame should be brushed.
