The basic requirement of the light pole manufacturing
Light represents a city's character and personality, so it should have a strong artistic effect. Its characteristic and individual character, beautify the top performance during the day, the appearance of the whole garden light want to consider the aesthetics of fusion of the square, the evening want to consider art lighting, lamp
light represents a city's character and personality, so it should have a strong artistic effect. Its characteristic and individual character, beautify the top performance during the day, the appearance of the whole garden light want to consider the aesthetics of fusion of the square, the evening want to consider art lighting, light color to foil the beauty of the square, and second, we should pay attention to ornamental value, that is to say, courtyard lamp itself should not only have beautiful appearance, but also beautify the lighting environment, can also be a city or a region's civilization symbol.
light pole should be of steel frame structure, after the hot dip galvanized 【 Compound and the iron substrate reaction was to make the molten metal and alloy layer, so that the substrate and coating combination of both. 】 Anti-corrosion treatment, with the steel wire rope hoist. Besides its lightningproof grounding system, also requires sufficient structural strength, easy to remove and install. All the joints should be stainless steel. Light pole in all kinds of power cable, communication cable should pass special fixture and reliable connection cable, can not bear weight. Third, the structure and basic structure size calculation, the main stem of 12 sprayed, facilitate transportation, product adopts cartridge, every section of the form. According to the shape of the appearance of the tenderee to determine structure parameters and manufacturing plants, set the magnitude 7 earthquake and wind loading, the plugin is not less than 500 mm in length, insert fitting clearance after no more than 3 mm, and provide reliable spacing device' Limit switch ( 制动设备) , it is to point to ensure the torsion Angle of elastic components parts does not exceed a certain limit. 】 And the real device.
light surface is smooth, no crack, leakage welding, continuous pores, bite edge and inequality. The center line of linear error is not more than rod long 0. 02%, rod body appearance without rough, traces and obvious flaw. Welding method for automatic submerged arc welding ( Submerged arc welding ( Submerged arc welding and electroslag surfacing, etc. ) Is a kind of method for welding arc under the flux layer combustion. 】 Pick up and ultrasonic testing Ultrasonic testing is the use of ultrasound can penetrate into the depths of the metal materials, and consists of a section into another section, on the edge of the interface reflection characteristics of flaws, a method to check the parts when the ultrasonic beam from the surface by the probe through the metal parts inside, encountered defects with parts respectively when bottom reflection wave, formation of pulse waveform on the screen, according to the pulse waveform to judge the defect position and size. 】 So as to meet the requirements of gbl1345 secondary standard. Socket connection with nails and jacking screws. Using hot dip galvanized anti-corrosion treatment. The galvanized layer is not less than 75 & mu; M, practical smooth surface, color are basically identical. Hammer test 【 An overview of the hammer test chuij and shiyan & # 91; 锤击试验) Gradually increased from the height of the drop hammer, has been until the deflection of heavy hammer to produce a specific impact test of other research studies the reinforced concrete beam under the various damage status of hammer test results, extracting the added across different displacement, velocity and near midspan plus a maximum of up and down of the acceleration response, analyzes three kinds of signal maximum value and the relationship between the load level, through the comparison, found that hammer test beam maximum displacement, maximum acceleration upwards, down and up and down the maximum acceleration increases with the loading level, the overall master monotonously increase or decrease trend, so you can use this a maximum of three kinds of signals to judge the damage degree of the structure. 】 No peeling, galvanized life not less than 20 years. Pure polyester powder coating should be made of high quality outdoor, the color should be determined, plastic layer quality should be stable, do not fade, no shedding, strong adhesion, resistance to ultraviolet radiation, service life not less than 20 years, thickness & ge; 80 um, comply with ASTM d339 - 83 standard. The surface level off is smooth.
