The signal lamp post, as the name suggests, is the pole to install the signal lamp, mainly for the traffic signal lamp pole. How much do you know about technical parameters and technical requirements of signal poles?
1. the structure size, connection mode and base size of all kinds of signal lamps are determined by calculation according to the wind, signal lamp or the size of plate surface and the way of support.
(1) basic wind pressure: according to "load code for building structures" GB50009-2001 value.
(2) seismic intensity: according to the regulations of "seismic intensity zoning map 1990 of China" and "classification standard for seismic fortification of buildings" GB50225-96, the quality of steel, welding rod and welding wire are selected according to the calculation results, and the quality of the products all meet the corresponding national standards.

The 2. signal lamp rod and the foundation are connected with the flange, and the flange plate at the bottom of the column is fixed on the pre buried anchor bolt in the concrete. It is safe and reliable, and the horizontal arm and the column are also connected with the flange, which is convenient for transportation and installation and debugging. The quality of the bolts, nuts and gaskets used to meet the corresponding national standards, the hole diameter, spacing and end distance of the bolt holes are all carried out according to the steel structure design specification and the steel structure design manual.
The 3. signal lamp pole column and the cross arm adopt the multilateral inverted cone, the force is reasonable, the cross section adopts the positive eight edge shape, the cross arm is less than 12 meters in 12 meters, the arm length is more than 12 meters, and the depth error is controlled within the range of + 5%L (L design insert value). The connection is reliable and the design is simple and generous.
The welding of 4. signal lamp rod adopts argon protection welding, automatic welding type submerged arc automatic welding, no slag, gas hole and other welding defects. The welding of important parts is tested to meet the corresponding welding specification requirements.
5. anticorrosion requirements: in addition to the basic framework, all of them are galvanized by hot dip galvanizing, and meet the requirements for corrosion protection and the thickness of zinc layer in GB2694-81 of transmission line tower manufacturing technology.
6. the components are properly packed before they leave the factory. After the factory is shipped, they are properly transported to avoid damage to the components. The fasteners and small items are identified separately, packed and transported, and easy to install.
After reading, I believe that there are some technical parameters and technical requirements for the signal pole. I hope I can help you.
