一种用于装配式建筑防雷的预制女儿墙接闪器节点结构
本技术涉及建筑防雷领域,尤其涉及一种用于装配式建筑防雷的预制女儿墙接闪器节点结构。
技术介绍
装配式混凝土结构建筑中,预制构件间的横向连接多采用现浇,采用传统统的土建施工连接方法,即可形成雷电水平通路;而装配式框架结构预制构件间纵向钢筋的连接,多采用套筒灌浆连接、浆锚搭接连接,不能满足LPS的电气连续性要求。且装配式建筑的女儿墙多为预制外挂板,施工时在上面直接安装接闪带可能损坏预制墙板。
技术实现思路
本技术的目的在于针对现有技术的缺陷和不足,提供一种用于装配式建筑防雷的预制女儿墙接闪器节点结构,该结构可保证现场安装对预制墙板的损伤最小,且满足防雷要求。为实现上述目的,本技术采用的技术方案是:一种用于装配式建筑防雷的预制女儿墙接闪器节点结构,包括有预制混凝土楼板、现浇柱、女儿墙、接闪器、屋面引下线、连接钢板、预制柱引下线;所述预制混凝土楼板为装配式建筑的叠合楼板结构,该预制混凝土楼板底部设置有凹槽,凹槽内浇筑有现浇混凝土楼板;所述预制混凝土楼板顶面依次叠合铺设有泡沫保温层和素混凝土屋面;所述预制混凝土楼板外侧修筑有现浇柱, ...
