山东电缆桥架我们在生活中已经见怪不怪了，足以说明它应用范围之广，但关于该产品，我们还是有很多方面的内容不甚了解，比如说桥架伸缩节的使用，这是做什么用的呢？

　　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?

　　电缆桥架进人施工现场，应提交下列资料产品出厂合格证、省市级质监站定期检验报告及有关技术鉴定文件等电缆桥架板材厚度应满足有关要求。热镀锌的电缆桥架镀层表面应均匀,无过烧、挂灰、局部未镀锌等缺陷。静电喷塑应平整、光滑、均匀、不起皮,无气泡、水泡桥架本身应平整,无扭曲变形,内壁应光滑、无毛刺桥架焊缝表面应均匀,不得有漏焊、裂纹、烧穿等缺陷。

　　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.

　　电缆桥架伸缩接头主要由左电缆桥架、右电缆桥架、内伸缩连接板、外伸缩连接板、软编织铜线、接地螺钉、电缆桥架左盖板、以及桥架的右盖板。

　　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.

　　山东电缆桥架由金属制成，金属热胀冷缩比较强。如果不加伸缩接头，桥架接头的连接就不会很紧，特别是超长的桥架，超长距离电缆桥架在高层和超高层建筑中的使用非常普遍。这些超长电缆桥架受热胀冷缩的影响比普通建筑中的桥架更为严重。如果处理不当，就会造成威胁。因此，需要电缆桥架安装伸缩接头。

　　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.

　　在铺设山东电缆桥架的过程中，难免会遇到建筑物伸缩缝、沉降缝振动的特殊环境造成破坏。电缆桥架安装规定，钢制电缆桥架直线段超过30m，铝合金或玻璃钢电缆桥架超过15m时，应有伸缩缝，连接时应使用伸缩缝；伸缩缝应设置在电缆桥架跨越建筑物伸缩缝的地方。桥架受到水平拉伸时，需要安装伸缩缝，防止建筑物水平拉伸；当电缆桥架受到垂直沉降时，需要安装伸缩缝，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.

　　山东电缆桥架伸缩节是做什么的？经过以上的了解可以看出，伸缩节对于山东电缆桥架而言起到的作用还是比较大的，所以要更好的使用施工，就要多多去了解去关注。更多内容就来网站www.sddlqj.cn咨询吧。

　　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.sddlqj.cn.
