桥架的基本结构引发的特殊性能

桥架的基本结构引发的特殊性能
Special Performance of Bridge Frame Initiated by Basic Structure
电缆桥架分为槽式、托盘式和梯架式等结构,由支架、托臂和装置附件等组成。(参见图1所示),选型时应留意桥架的所有零部件是否符合系列化、通用化、标准化的成套要求。建筑物内桥架能够独立假定,也能够附设在各种建(构)筑物和管廊支架上,应表现结构简单,造型漂亮、配置灵活和修理便利等特色,悉数零件均需进行镀锌处理,装置在建筑物外露天的桥架,如果是在附近海滨或归于腐蚀区,则材质有必要具有防腐、耐潮气、附着力好,耐冲击强度高的物性特色。
Cable bridge is divided into trough type, tray type and ladder type structure, which is composed of bracket, bracket and device accessories. As shown in Figure 1, attention should be paid to whether all components of the bridge meet the requirements of serialization, generalization and standardization. Bridges in buildings can be assumed independently or attached to various buildings and pipe galleries. They should be simple in structure, beautiful in shape, flexible in configuration and convenient in repair. All parts should be galvanized. Bridges installed in the open air outside buildings are made of materials if they are located near the seashore or in corroded areas. It is necessary to have the physical characteristics of anticorrosion, moisture resistance, good adhesion and high impact strength.
为了减轻分量还能够选用铝合金电缆和玻璃钢桥架,其外形尺寸,荷载特性均与钢质桥架基本附近,因为铝、钢比重不同(A1=2.7,Fe=7.86,按分量核算,铝钢之比约为1:3,根据两种材质的市场价折算,铝合金桥架的造价费用较之同类镀锌钢桥价要高出2.0倍,铝合金桥架具有漂亮,分量轻、装置便利等优点,近年来,铝合金桥架已在有的工程中加以使用。
In order to reduce the weight, aluminum alloy cable and FRP bridge can also be selected. Its shape, size and load characteristics are basically near the steel bridge, because the proportion of aluminum and steel is different (A1 = 2.7, Fe = 7.86). According to the component calculation, the ratio of aluminum to steel is about 1:3. According to the market price of the two materials, the cost of aluminium alloy bridge is lower than that of the same kind of galvanized bridge. The price of steel bridge is 2.0 times higher. Aluminum alloy bridge has the advantages of beautiful, light weight and convenient installation. In recent years, aluminum alloy bridge has been used in some projects.
为了防止电磁辐射的干扰(EMC),在桥架的规划中,应考虑桥架的封闭性。
In order to prevent electromagnetic radiation interference (EMC), the closure of the bridge should be considered in the planning of the bridge.

1. Bridge structure cable tray is divided into trough type, tray type and ladder type, which is composed of bracket, bracket arm and equipment accessories. When selecting the type, we should pay attention to whether all parts of the bridge meet the requirements of serialization, generalization and standardization. Bridges in buildings can be assumed independently or attached to various buildings and pipe galleries. They should be simple in structure, beautiful in shape, flexible in configuration and convenient in repair. All parts should be galvanized.
