What is the national standard thickness of aluminum alloy bridge?
This problem needs to be analyzed in detail, because the national standard thickness of aluminum alloy bridges with different types and different specifications is different.
At present, according to the national standard thickness standard of aluminum alloy bridge, what is relatively clear is the JB/T 10216-2013 standard, which is a mechanical industry standard issued by the Ministry of Industry and Information Technology.
Needless to say, directly on the standard table 1, aluminum alloy trough bridge can be seen from the above table, the width of aluminum alloy trough bridge determines the thickness of aluminum alloy groove bridge, the specific rules are as follows: width < = 150mm, bridge thickness 1.2mm width > 150mm width < = 300mm, bridge thickness 1.5mm width > 300mm width < = 500mm, bridge thickness 2.0mm width > 500mm width < = 800mm, bridge thickness 2.2mm width > 800mm.
As can be seen from the table above, the width of aluminum alloy tray type bridge determines the thickness of aluminum alloy tray type bridge. The specific rules are as follows: width < = 150mm, bridge thickness 1.2mm width > 150mm width < = 300mm, bridge thickness 1.5mm width > 300mm width < = 500mm, bridge thickness 2.0mm width > 500mm width < = 800mm, bridge thickness 2.2mm width > 800mm.
The thickness of bridge is 2.5mm3, aluminum alloy ladder bridge can be seen from the above table. The width of aluminum alloy ladder bridge determines the thickness of aluminum alloy ladder bridge. The specific rules are as follows: width < = 150mm, bridge thickness is 1.2mm width > 150mm width < = 300mm, bridge thickness is 1.5mm width > 300mm width < = 500mm, bridge thickness is 2.0mm width > 500mm width < = 800mm, bridge thickness is 2.2mm width > 800mm.
The thickness of the bridge is 2.5mm supplementary note: in addition, if the width of the above aluminum alloy trough bridge, aluminum alloy tray bridge and aluminum alloy ladder bridge is more than = 400mm, then the thickness of the bottom plate is allowed to be lower than that of the side plate, but in order to ensure the safety load of the bridge tray, a horizontal gear must be added.
You can select the thickness of the aluminum alloy bridge according to the standards specified by the project.
