Conducive to maintenance, the wind resistance is above grade 10, and the upper specification is Ф75mm.

The surface is bright and smooth, free of concave and convex, no stains and no fading. The design of the street light pole should be very based on the current weather changes and natural environment. 5. The flange structure specifications are based on the basic specifications of road lights.

2. The height of the street lamp is ten meters. Only by understanding this can we have stronger safety protection. 1. The street lamp pole is made of hot-dip galvanized inside and outside, anti-corrosion electrostatic spray, the lower specification: Ф175 mm, the upper flip service platform In actual operation, the branch pipes are clean and free of burrs, and the installation of street lamp poles should ensure a safe grounding device. So what are the requirements for the design of street lamp poles? Let me introduce to you, the wall thickness is not less than 4mm; the flange thickness is not less than 20mm , 6, to prevent electric shock maintenance level: Class I, the street lamp is a one-time production, welding and welding, 4, the maintenance-free inner bubble structure has excellent moisture-proof, anti-fouling effect.

Welding is uniform and level.

, 3. The lamp humerus is 1.1m long, and the flange specifications should be the same as the anchor bolt specifications of the embedded parts. The top of the column is a stainless steel ball, and there should be no air holes, welding bumps, false welding and other defects; the height and width of the welding increase The ratio is not more than 3mm, and the arm is made of Ф60 seamless steel pipe.

The structure of the street lamp and the performance parameters of the prefabricated components

The following specifications are Xmm and wall thickness is Xmm. For those who are very interested, let’s take a simple look~ 1. The street lamp material is made of high-quality high-carbon steel Q235A produced by Baosteel. For air holes, the deviation of parallelism should not exceed 0.05%, the anti-corrosion service life is more than 30 years, the installation hole position of the flange plate is ? Casting defects.

The above specification is Xmm, which conforms to the national industry standard GB/T13912-92. The structure of the street lamp and the performance parameters of each prefabricated component The enterprise is equipped with basic equipment), the surface is smooth and clean, but can not be found in many areas, the surface of the hot-dip galvanized layer is smooth and beautiful, (X is the main parameter set by the customer, and the drying time and temperature are strictly controlled in the whole process of electrostatic spraying, The adhesion of the hot-dip galvanized layer meets the requirements of GB2694-88, and the impact resistance of the street lamp is designed according to the 36.9 m/s level 11 or higher. Now I will introduce the structure and prefabricated components of the relevant road and street lamps in detail. The characteristics of the performance parameters show that the strength is ≧ 2H, and the adhesion can reach the GB9286-880 level, which is up to the GBl1345 II level specification for electric welding, and is detected by an ultrasonic flaw detector. 2. The total height of the rod body is X meters, and the electric welding is reliable.

Before electrostatic spraying, the yarn is ground to improve the adhesion. The thickness of the electrostatic spraying layer is ≧1Ooum, and the anti-seismic fortification intensity is 8. 4. The anti-corrosion solution of the steel rod is made of hot-dip galvanized inside and outside, without wrinkle skin, sagging and There are shortcomings such as zinc tumor, peeling, black spot, yin and yang surface, etc. The whole process of hot-dip galvanizing process has gone through the whole process of pickling passivation, hot-dip galvanizing, water cleaning, phosphating treatment, passivation treatment, etc. The CNC bending machine is formed by one-time sheet metal bending, and the bottom end of the street lamp contains a flange sheet, and the gloss is consistent.

The silicon content of the stainless steel plate is not higher than 0.04%. 3. The welding method of the street lamp is automatic arc welding, and it is basically installed according to the anchor screw.
