5·12地震灾区活动板房如何科学防雷

Scientific Lightning Protection of the Pre-fabricated Houses in 5·12 Earthquake Disaster Areas

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 prefabricated houses should not be adopted. If the temporary dwellings houses adopt doublelayer colorful steel plate and metallic framework structure, the overall effective grounding can prevent from the harm of direct lightning strikes.
