摘要
建筑物防雷装置的设置对建筑物的整体安全性起到至关重要的作用。国家会议中心二期项目为超大型屋面,分为平屋面和拱屋面两部分,主要由玻璃和铝板构成,总面积约7万m2,属第二类防雷建筑物。防直击雷的措施宜采用装设在建筑物上的避雷网带或避雷针,或由其混合组成的接闪器,综合考虑建筑物自身特点及周边环境情况,经专家论证会确定采用预放电避雷针的设计技术。
The setting of lightning protection devices plays a vital role in the overall safety of a building.The China National Convention Center Phase II belongs to the second category of lightning protection buildings,which has a super-large roof including flat roof and arched roof and mainly composed of glass and aluminum panels,with a total area of about 70,000 m2.The measures against direct lightning strike prefers to adopt lightning protection mesh belts or lightning rods installed on the building,or lightning arresters composed of their mixture.The pre-discharge lightning rod technology will be adopted after demonstrated by experts on the basis of synthetically considering the building’s characteristics and the surrounding environment.
