山東電纜橋架我們在生活中已經見怪不怪了，足以說明它應用范圍之廣，但關于該產品，我們還是有很多方面的內容不甚了解，比如說橋架伸縮節的使用，這是做什么用的呢？

　　Shandong cable bridge we have not seen strange in life, enough to explain its wide range of application, but about the product, we still have many aspects of the content is not very understanding, such as the use of the bridge expansion joint, what is this used?

　　電纜橋架進人施工現場，應提交下列資料產品出廠合格證、省市級質監站定期檢驗報告及有關技術鑒定文件等電纜橋架板材厚度應滿足有關要求。熱鍍鋅的電纜橋架鍍層表面應均勻,無過燒、掛灰、局部未鍍鋅等缺陷。靜電噴塑應平整、光滑、均勻、不起皮,無氣泡、水泡橋架本身應平整,無扭曲變形,內壁應光滑、無毛刺橋架焊縫表面應均勻,不得有漏焊、裂紋、燒穿等缺陷。

　　When the cable tray enters the construction site, the following information shall be submitted: factory certificate of products, regular inspection report of provincial and municipal quality supervision station and relevant technical appraisal documents, etc. The thickness of cable tray plate shall meet the relevant requirements. The coating surface of the hot-dip galvanized cable bridge should be uniform, without over-burning, hanging ash, local ungalvanized defects. Electrostatic spraying should be flat, smooth, uniform, no skin, no bubble, bubble bridge itself should be flat, no distortion, the inner wall should be smooth, no burr bridge weld surface should be uniform, no leakage welding, cracks, burn through and other defects.

　　電纜橋架伸縮接頭主要由左電纜橋架、右電纜橋架、內伸縮連接板、外伸縮連接板、軟編織銅線、接地螺釘、電纜橋架左蓋板、以及橋架的右蓋板。

　　Cable tray expansion joint is mainly composed of left cable tray, right cable tray, internal expansion connecting plate, external expansion connecting plate, soft braided copper wire, ground screw, left cover plate of cable tray, and right cover plate of bridge.

　　山東電纜橋架由金屬制成，金屬熱脹冷縮比較強。如果不加伸縮接頭，橋架接頭的連接就不會很緊，非常是超長的橋架，超長距離電纜橋架在高層和超高層建筑中的使用非常普遍。這些超長電纜橋架受熱脹冷縮的影響比普通建筑中的橋架更為嚴重。如果處理不當，就會造成安全威脅。因此，需要電纜橋架安裝伸縮接頭。

　　Shandong cable bridge is made of metal, which is relatively strong in thermal expansion and contraction. If there is no expansion joint, the connection of the bridge joint will not be very tight, especially the super long bridge. The super long distance cable bridge is very common in high-rise and super high-rise buildings. These ultra-long cable Bridges are more seriously affected by thermal expansion and contraction than Bridges in ordinary buildings. If not handled properly, it can pose a security threat. Therefore, the cable bridge needs to be installed expansion joint.

　　在鋪設山東電纜橋架的過程中，難免會遇到建筑物伸縮縫、沉降縫振動的特殊環境造成破壞。電纜橋架安裝規定，鋼制電纜橋架直線段超過30m，鋁合金或玻璃鋼電纜橋架超過15m時，應有伸縮縫，連接時應使用伸縮縫；伸縮縫應設置在電纜橋架跨越建筑物伸縮縫的地方。橋架受到水平拉伸時，需要安裝伸縮縫，防止建筑物水平拉伸；當電纜橋架受到垂直沉降時，需要安裝伸縮縫，以防止建筑物下沉。

　　In the process of laying shandong cable bridge, it is inevitable to encounter the special environment of vibration of expansion joints and settlement joints of buildings, causing damage. Cable tray installation provisions, steel cable tray straight section more than 30m, aluminum alloy or glass fiber reinforced plastic cable tray more than 15m, there should be expansion joints, expansion joints should be used when connecting; The expansion joint should be set at the place where the cable bridge spans the expansion joint of the building. When the bridge is stretched horizontally, it is necessary to install expansion joints to prevent the building from stretching horizontally; When the cable tray is subjected to vertical settlement, expansion joints need to be installed to prevent the building from sinking.

　　山東電纜橋架伸縮節是做什么的？經過以上的了解可以看出，伸縮節對于山東電纜橋架而言起到的作用還是比較大的，所以要更好的使用施工，就要多多去了解去關注。更多內容就來網站www.ymmgjx.net咨詢吧。

　　What is the expansion joint of shandong cable bridge? After the above understanding, it can be seen that the expansion joint plays a large role in shandong cable bridge, so to better use and construction, we must learn more to pay attention to. For more information, visit www.ymmgjx.net.
