A: principle of type selection of light, the first part of a, 1, elevating parking structure light by the light pole assembly ( Contain light plate, lightning rod) Monitoring equipment, light source system, lift system, control system composed of 2, light, material thickness, reinforcement cage, lamp base should be full of
a: light, 【 Light, generally refers to more than 15 meters steel conical light pole and high-power modular fixtures are composed of new type of lighting. 】 The selection principles of
the first part of
a, structure
1, elevating parking lot light by the light pole assembly ( Contain light plate, lightning rod [ Lightning, and lightning protection needle, is used to protect buildings, tall trees, etc to avoid lightning device. 】 ) Monitoring equipment, light source system, lift system, control system of
2, light, material thickness, reinforcement cage' Reinforcing cage main role as a pillar of longitudinal reinforcement stress is in the same way, mainly plays a role of tensile and compressive strength of concrete but high tensile strength is very low. 】 , lamp base should meet the requirements of the local wind, local geological conditions
the second part of
product requirements and technical specifications:
( A) , light pole, conform to the technical conditions 'lift growing lighting device ( QJ/T312/1998) With the growing lighting technical conditions' The conditions of high lighting technology ( CJ/T 3076- 1998). 'Standard for the first time put forward urban construction industry standards. 】 ( QJ/T3076/1998) ', city road lighting design standard' City road lighting design standard is a standard issued by the state, used in the specification on the urban road construction about the lighting requirements, specific see city road lighting design standards. 】 ( QJJ4591) And acceptance criteria of the lamps in the current provisions of the state requirements. High lamp is made of Shanghai baosteel Q235 【 Also known as A3 steel Q235 plain carbon structural steel. 】 Plate, three variable diameter, wall thickness, respectively, 10 mm, 12 mm, 8 mm rod for conical octagon or dodecagon, hot dip galvanized inside and outside, white plastic spraying. Splice length is greater than the plug it big end diameter of 1. 5 times. ( Construction of the foundation should be with high lamp manufacturer after butt welding of reinforcing cage, adopts double cap tight hoop, and C20 concrete coating screws) Resistance to 40 m/s wind speed, conform to the GBJ9 and the relevant provisions of the solar street light 5 GBJ13 street lamp; Earthquake magnitude 7 or higher, in conformity with the relevant provisions of the GBJ11's. Light pole overall galvanizing anti-corruption processing, coating quality in line with the GB/T9700 GBJ36011, and the relevant provisions of the standard GB/T1373, galvanized thickness not less than 86 microns; Surface electrostatic spraying, coating thickness is not less than 100 microns, the surface is smooth, does not change color, use life not less than 30 years. Light pole welding quality conforms to the requirements of GB/T12469, no impact strength of the cracks, slag inclusion, flash, burn through, arc pit and needle hole, and no defects such as wrinkle and interrupt. At the bottom of the light pole has rainproof maintenance door, and special anti-theft capes corrosion resistant locks.
( 2) , light plate, light plate of material of high quality low carbon steel material, the overall after galvanizing, surface electrostatic spraying, the service life of not less than 20 years, lamp panel to reach the top using light pole position is equipped with mechanical limit switch
