橋架的基本結構引發的特殊性能
Special Performance of Bridge Frame Initiated by Basic Structure
電纜橋架分為槽式、托盤式和梯架式等結構,由支架、托臂和裝置附件等組成。(參見圖1所示),選型時應留意橋架的所有零部件是否符合系列化、通用化、標準化的成套要求。建筑物內橋架能夠獨立假定,也能夠附設在各種建(構)筑物和管廊支架上,應表現結構簡單,造型漂亮、配置靈活和修理便利等特色,悉數零件均需進行鍍鋅處理,裝置在建筑物外露天的橋架,如果是在附近海濱或歸于腐蝕區,則材質有必要具有防腐、耐潮氣、附著力好,耐沖擊強度高的物性特色。
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.
為了減輕分量還能夠選用鋁合金電纜和玻璃鋼橋架,其外形尺寸，荷載特性均與鋼質橋架基本附近,因為鋁、鋼比重不同(A1=2.7,Fe=7.86，按分量核算,鋁鋼之比約為1：3,根據兩種材質的市場價折算,鋁合金橋架的造價費用較之同類鍍鋅鋼橋價要高出2.0倍,鋁合金橋架具有漂亮,分量輕、裝置便利等優點,近年來,鋁合金橋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.
為了防止電磁輻射的干擾(EMC)，在橋架的規劃中，應考慮橋架的封閉性。
In order to prevent electromagnetic radiation interference (EMC), the closure of the bridge should be considered in the planning of the bridge.
