5·12地震灾区活动板房如何科学防雷
|
摘要
5·12汶川特大地震发生后,在灾区搭建了大量的活动板房,活动板房的所有金属体应做良好接地,且应与其它接地共用接地体。应根据灾区各地的雷暴日数和活动板房的结构,采取相应的防雷措施。在活动板房的上空架设空中避雷线、避雷针的做法不可取。若过渡安置房采用双层彩钢板和金属骨架结构,则在做好整体良好接地的情况下,已能起到防护直击雷的作用。
Since the 5·12 Wenchuan Earthquake occurred, a lot of pre-fabricated houses have been built. All the metal bodies in the pre-fabricated houses should be effectively grounded and share the common grounding bodies with other earthing. The lightning protection of the pre-fabricated houses should be based on the thunderstorm days and their structures and taking corresponding measures. Overhead lightning conductors or lightning arresters above the pre-fabricated houses should not be adopted. If the temporary dwellings houses adopt double - layer colorful steel plate and metallic framework structure,the overall effective grounding can prevent from the harm of direct lightning strikes.
