The weak current system of intelligent building usually consists of multiple information monitoring and communication facilities and other corresponding systems. The cable bridge can be divided into slot, tray and ladder structure, etc. Attention should be paid to whether all the components of the cable bridge meet the requirements of serialization, generalization and standardization. Can independently set up within the building bridge, also can be attached on all kinds of buildings and pipe rack bracket, should reflect a simple structure, beautiful modelling, flexible configuration, and maintenance is convenient wait for a characteristic, all parts are to be galvanized processing, installation outside the building open bridge, if it is in near the sea or belong to the corrosion area, must have the anti-corrosion material, resistant to moisture.
The structural strength of the cable tray is higher than that of the ordinary flat plate. The bottom plate, side and cover plate of the cable tray are all made of corrugated structure, which suppresses the block-concave and convex structure similar to track, and increases the strength of the cable tray. At the same time, the heat dissipation area increases, the structure is convenient for ventilation and heat exchange, and also reduces the energy loss of cable laying in the cable bridge.
The low thickness plate of the cable bridge can meet the original load capacity requirements, which will greatly reduce the use of raw materials.
Cable bridge is widely used in the construction industry, mainly including trough bridge, galvanized bridge, ladder bridge, stainless steel bridge and so on.
