Lamppost technology description:
1. The height of the pole is 5-15 meters. The main pole is formed by a large bending machine at a time. The wall thickness is 2.5-6mm. The specific appearance and size are customized according to user requirements.
2, material
The lamppost is made of high quality low silicon carbon steel Q235A steel (where Si≤0.04%, yield strength >245Mpa); the material meets the performance standard: GB699-88.
3, welding process
The entire street light pole body shall be free of any cracking, leakage welding, continuous air hole, undercut, etc. The weld seam is smooth and flat, without convex and concave undulations, without any welding defects, and a welding flaw detection report shall be provided. The welding standard is based on: GB/T3323-1989III. The safety standard complies with the national standard GB7000.1-7000.5-1996.
4, electrical door
a. The electrical door is plasma cut.
b. The electrical door is integrated with the lamp body, and the boss is not welded at the opening, and the structural strength is high.
c. With reasonable operating space, the door has electrical installation accessories.
d. The gap between the door and the rod should not exceed 1 mm, and it has good waterproof performance.
e. There is a special fastening system with good anti-theft performance, and the fixing bolts are opened by non-generic tools.
f. Electrical door should have high interchangeability, reasonable operating space inside the door, providing 3% electrical door fittings
g. Firmly weld an M8×30 ​​bolt to the lamp post at the bottom left of the lamp post to perform hot-dip galvanizing treatment to connect the cable PE wire.
5, hot-dip galvanizing process
The inner and outer surfaces of hot dip acid should be treated with rust, and the thickness ≥75um conforms to GB-/T13912-92 standard. The design service life should be no less than 30 years, the galvanized surface should be smooth and beautiful, the color is basically the same, and the skin can not be peeled off after slamming test. Provide galvanized test reports.
6, spray molding process
Spray plastic should use outdoor pure polyester plastic powder, the color is white, the plastic layer quality is stable, does not fade, does not fall off. Strong adhesion, strong resistance to the sun's ultraviolet rays, anti-ultraviolet rays, and should be along the lake city and key salt areas. Design life ratio is less than 30 years, thickness ≥ 80um, in line with ASTM D3359-83 standard. Provide a spray test report. Spray protection requirements: film thickness is not less than 40um, strong adhesion, blade scratches (15 * 6mm square) can not skin, does not fall off. The surface is smooth and the color is basically the same.
7, design ability
a. According to the requirements of the corresponding wind speed, the calculation of the force of the rod according to the shape diagram of the light pole is provided.
b. The strength and surface structure of the formed square steel used in the rod body must conform to the corresponding national standards.
C. Seal the pole and cover the top with waterproof air.
8, verticality test
After the pole is upright, use the theodolite to check the verticality between the pole and the horizontal, and the verticality should be less than or equal to two thousandths.
9, the sense of the body
The shape and size meet the requirements, the overall appearance is elegant, the surface of the rod is smooth and uniform, and the color is uniform. The galvanized layer is smooth and flat, and the sprayed layer has strong adhesion without peeling off.
10. All fixing bolts, nuts, etc. are made of stainless steel (except for anchor bolts and nuts).
11. The inner cable passage of the lamp post is unobstructed, easy to thread, and has no sharp edges, burrs, teeth and the like to avoid damage to the cable.
12, the light pole meets lightning protection and grounding requirements, 2 ambient temperature: -15-50 degrees Celsius; ambient wind speed: 40m / s; anti-seismic intensity: 8; corrosion resistance: 30 years
