Traffic sign pole manufacturers should pay attention to the two technologies of galvanizing and spraying during the production process. A good surface treatment method can make the surface of the traffic sign pole smooth and beautiful. Traffic sign pole manufacturers should make good foundations and basic norms. It is 600mm×600mm×800mm, the anchor bolt is 6-M32mm×500mmH, and a C30 concrete base is used. The base process is vibrating with a vibrating rod. In the base system, its height is 5-10CM lower than the road markings to restore flowers, plants, etc., and coordinate with the surrounding environment. In order not to affect the appearance, protective paint must be done well.
1. The height of the traffic sign pole is 5-15 meters. The main rod is formed by a large bending machine in one go, with a wall thickness of 2.5-6mm. The specific appearance size is customized according to user requirements.
2. Material: The traffic sign pole is made of high-quality low-silicon carbon steel Q235A steel (Si≤0.04%, yield strength>245Mpa); the material meets the implementation standards: GB699-88.
3. Welding process: The entire traffic sign pole body should be free of cracks, missing welding, continuous pores, undercuts, etc. The welds should be smooth and flat, without bumps and undulations, and there should be no welding defects. A welding flaw detection report must be provided. Welding standard basis: GB/T3323-1989III. The safety standards comply with the national standard GB7000.1-7000.5-1996. .
4. Hot-dip galvanizing process of monitoring rod: both the inner and outer surfaces are hot-dip acid treatment, with a thickness of ≥75um, and complies with the GB-/T13912-92 standard. The design service life is no less than 30 years, and the galvanized surface should be smooth and beautiful. The colors are basically the same, and there is no peeling or peeling after hammering. Provide galvanized inspection report.
5. Plastic spraying process: Plastic spraying should make pure polyester plastic powder outside the user. It has strong adhesion, strong UV resistance, and UV resistance, so it should be along the lake city and the main saline-alkali land. The design service life ratio is less than 30 years, the thickness is ≥80um, and it complies with the ASTMD3359-83 standard. Provide a spray test report. Plastic spray protection requirements: the film thickness is not less than 40um, the adhesion is strong, the blade scratched (15*6m meters square) cannot be peeled off or fall off. The surface is smooth and flat, and the color is basically the same.
6. Design ability
one. According to the requirements for bearing the corresponding wind speed, a calculation book for the rod body force according to the lamp pole profile is provided.
Bay. The strength and surface structure of the molded square steel used for rod bodies must comply with the corresponding standards.
C. Seal the rod and wrap the top to prevent gas from entering.
7. Verticality check: After the monitoring rod manufacturer is upright, use the theodolite to check the perpendicularity of the lamp pole and the horizontal. The verticality should be less than or equal to two thousandths.
8. Appearance of the rod body: the shape and size meet the requirements, the overall appearance is beautiful and elegant, the surface of the rod body is smooth and consistent, and the color is uniform. The galvanized layer is smooth and smooth, and the plastic spray layer has strong adhesion and does not peel off.
9. All fixing bolts and nuts are made of stainless steel (except anchor bolts and nuts).
10. The cable threading channel inside the lamp pole is unobstructed and easy to thread, and there are no sharp edges, burrs, teeth, etc. to avoid damaging the cable.
11. The traffic sign pole manufacturer meets the requirements for lightning protection and grounding. 2. Ambient temperature: -15-50 degrees Celsius; Ambient wind speed: 40m/s; Earthquake intensity: 8; Corrosion resistance: 30 years.
