The construction of cable bridge can be undertaken independently, and can also be connected to the support of various buildings and pipeline corridors. It should reflect the simple structure, beautiful appearance, flexible configuration and convenient maintenance. All components need to be galvanized. What should be paid attention to when building Jinan cable bridge?
为了减肥也可以采用铝合金和玻璃纤维增强塑料电缆桥架,外观尺寸,负荷特性与钢桥基本相似,由于铝、钢重力(A1 = 2.7、铁= 7.86)的重量,铝和钢约1:3的比例,根据两种材料的市场价格折扣,铝合金桥造价造价价格比同类镀锌钢桥高1.5 ~ 2.0倍的铝合金电缆桥架美观、重量轻、安装方便等优点，近年来，铝合金桥的应用已在一些工程中得到应用。
In order to lose weight, aluminum alloy and glass fiber reinforced plastic cable bridge can also be used. The appearance size and load characteristics are basically similar to steel bridge. Because of the weight of aluminum and steel gravity (A1 = 2.7, iron = 7.86), the proportion of aluminum and steel is about 1:3. According to the market price discount of the two materials, the cost of aluminum alloy bridge is 1.5 ~ 2.0 times higher than that of similar galvanized steel bridge, which is beautiful and light in weight In recent years, the application of aluminum alloy bridge has been applied in some projects.
What should be paid attention to in the construction of Jinan cable bridge?
Matters needing attention
1. The load support spacing of XQJ cable tray device is large, which should be less than the allowable load and support span.
2. In order to increase the use of cable bridge in the future, some space should be reserved when choosing the width of cable bridge in Shandong area.
3. When there are few power cables and control cables, the same cable tray can be installed, but the power cables and control cables shall be laid separately with partition in the middle.
4. When the cable tray is laid horizontally, the connector between trays shall be set at about 1 / 4 of the span and the cable operation level shall be fixed about every 2 meters, while the cable running vertically shall be fixed about every 1.5 meters.
5. The cable tray device shall be reliably grounded. If the bridge is used as the main grounding line, the end of each layer of bridge is connected with the main grounding line by 16mm2 copper wire (in parallel), and the long-distance cable bridge is grounded every 30-50m.
In addition to the shielding cover, the outdoor device shall be installed on the upper protective cover to prevent the sun and rain. If it is installed by welding, the welding thickness shall not be less than the thickness of the base material. The welding joint must be treated with anti-corrosion treatment.
