防雷设计说明
Notes to Lightning Protection Design
1.建筑物防雷:
1. Building Lightning Protection:
本楼年雷击次数为0.0541次/a,按《建筑物防雷设计规范》第2.0.4条规定属于第三类防雷建筑物。建筑物的防雷装置应满足防直击雷、防雷电感应及雷电波的侵入,并设置总等电位联结。
The number of lightning of the building is 0.0541 times/a every year, and it belongs to the third class building according to the provisions of Article 2.0.4 stipulated in Code for design of lightning protection of buildings. Building lightning protection devices shall prevent the invasion of anti-direct lightning, induction lightning and lightning waves, and the main equipotential bonding is set.
2.接闪器:
在屋面及女儿墙顶部设置∅10镀锌圆钢作避雷带。屋顶避雷带连接网格不大于20mX20m或16mx24m。
2. Air-termination system:
∅10 galvanized round steel is set at the roof and the top of parapet as lightning belt. The grid connected the roof lightning belt is not greater than 20mX20m or 16mx24m.
3.引下线:
Down lead
利用建筑物钢筋混凝土柱子或剪力墙内两根∅16以上主筋通长焊接作为引下线,引下线间距不大于25m.
The reinforced concrete columns of the building or two ∅16 above reinforcement within the shear wall are in full length welded as down lead, and the spacing between down leads is not more than 25m.
4.接地极:Grounding pole:
利用建筑物基础作接地体,利用-40x4渡锌扁钢将结构独立基础内的钢筋焊接连通作接地装置,要求接地电阻不大于1欧, 如不满足要求,应另加设人工接地装置。引下线上端与避雷带焊接,下端与接地极焊接。在有 符号的引下线所在结构柱上距地0.5m处连接板(接地电阻测试点)。
The building basis is used as the grounding body, -40x4 galvanized flat steel is used to weld and connect reinforced bars within the independent basis of the structure as the grounding device, and the grounding resistance is less than 1ohm as required; if not, an additional artificial grounding device should be set. The upper end of the down lead is welded and connected with the lightning belt, and the lower end is welded with the grounding pole. Plates are connected 0.5m from the ground on the structure column of the down lead where there is symbol (earth resistance test point).
5.凡突出屋面的所有金属构件、金属屋面、金属屋架、金属雨棚、钢柱等均与避雷带可靠焊接。突出屋面的所有金属构架至少应在两对角支撑点处与避雷带可靠焊接。不同高度的屋面接闪器应利用结构柱内主筋或沿墙暗设∅10镀锌圆钢焊接连通。竖直敷设的金属管道及金属物的顶端和底端应与防雷装置连接。电源引入的总配电箱处均装设过电压保护器。
5. All the metal members prominent on the roof, metal roofing, metal roof truss, metal canopy, steel columns and others are welded with lightning belts reliably. All the metal members prominent on the roof should be welded with lightning belts reliably at least at two diagonal support points. Different heights of roof air-termination systems should be welded and connected by use the main reinforcement in the structure column or by setting ∅ 10 galvanized round steel along the wall. Vertically laid metal pipelines and metal top and bottom should be connected with lightning devices. An over-voltage protector is installed at the general power distribution box where the power supply is input.
