The weak current system of intelligent building usually consists of multiple information monitoring and communication facilities and other corresponding systems. Aluminum alloy bridge frame can be divided into slot structure, tray structure and ladder structure, etc. Attention should be paid to whether all parts of aluminum alloy bridge frame meet the requirements of serialization, generalization and standardization. Can independently set up within the building aluminum alloy bridge, also can be attached on all kinds of buildings and pipe rack bracket, should reflect the structure is simple, modelling beautiful, 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.
Structural strength of aluminum alloy:
The structural strength of aluminum alloy bridge frame is higher than that of ordinary plane plate. In the structure of aluminum alloy bridge frame, the bottom plate, side edge and cover plate all adopt corrugated structure, which suppresses the block-concave and convex structure similar to track, and increases the strength of aluminum alloy bridge frame. 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 cables laid in the aluminum alloy bridge. Aluminum alloy bridge with low thickness plate can meet the original load capacity requirements, which will greatly reduce the use of raw materials.
Aluminum alloy bridge structure:
Deformation aluminum alloy can withstand pressure processing, mechanical properties than cast. Can be processed into various shapes and specifications of aluminum alloy. Mainly used for manufacturing aviation equipment, daily necessities, building doors and Windows, etc. Cast aluminum alloys are used in as-cast condition. In fact, according to the chemical composition can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum zinc alloy and aluminum rare earth alloy.
Aluminum alloy plate, according to the needs of the plate structure or embossed stamping structure, some aluminum alloy can use heat treatment to obtain good mechanical properties, physical properties and corrosion resistance. Among them, there are simple al-si alloys (which cannot be strengthened by heat treatment, with low mechanical properties and good casting performance) and special al-si alloys (which can be strengthened by heat treatment, with high mechanical properties and good casting performance).
