Your high lamp and street lamps to light pole factory column evaluation specification to know more

Now a lot of areas, have been used in high lamp, light shine on large scale, is indispensable outdoor lighting lamps square or terminal. But high lamp light pole of the checking standard but there are a lot of people don't understand. Today high lamp is a simple talk about traffic light fittings

now has been used in many areas high lamp, light mass, is square or terminals of outdoor lighting. However, there are a lot of people don't understand high lamp inspection standard. Today, high lamp manufacturers will talk about traffic light fittings and high lamp light pole inspection standard. At present, our country is not the criterion for testing high lamp light pole structure strength. General reference to the tall and straight line structure planning standards ', 'load standard for the design of building structures' and 'standard of steel structure planning' implementation. This section calculation will only apply to seamless steel tube rod and welding rod taper tip. Light pole of intensity are considered in calculating the wind effect on the light, formed by bending stress and shear stress should not be more than the allowable stress of light pole. However, when high lamp pole, street lamp manufacturers planning basic wind pressure of 0. 56 kn /, that is, 10 wind ( 30m/s) 。 Light of seismic fortification intensity should be according to the magnitude 8 earthquake intensity. When planning the seismic intensity is greater than or equal to 7 degrees, should check the seismic intensity. Can check method is the bottom shear method. According to the requirements of seismic planning should choose as far as possible for seismic site and foundation, therefore should choose lightweight high strength materials, shape is simple, as long as the light body mass and stiffness of symmetrical distribution, mass center and stiffness center should overlap, as far as possible to ensure the integrity of the structure. For seismic calculation, the bottom shear method and approximate simplified method can be used in the cylindrical structure, chimney, water tower and high lamp. Experience is knowable, light, external force is mainly wind load, thus calculating the wind load is the key. Under wind load, light on the bottom flange of all anchor bolt by wind shear, because the wind loads on the lamp, lamp post at the bottom of the flange of the anchor bolt is generally regarded as half and half.
