一种用于装配式建筑防雷的预制柱内引下线节点结构
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柱内引下线节点结构。
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。
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柱内引下线节点结构,该结构能使防雷引下线与预制柱内作为引下线的钢筋相连通,且对结构损伤小。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柱内引下线节点结构,包括有现浇楼板、预制叠合梁、预制柱、预制柱底部附加导体、连接钢板、预制柱顶部附加导体;所述现浇楼板为装配式建筑的T型现浇楼板结构,该现浇楼板结构底面中部T型凸出两侧贴合修筑有预制叠合梁;所述现浇楼板T型凸出顶部上和底部下均修筑有预制柱,该预制柱为钢筋混凝土柱结构,且预制柱内设置有预制柱内主钢筋;所述预制柱内主钢筋为由一圈绕成环形的竖直钢筋和若干个环箍组成的钢筋框架,该预制柱内主钢筋贯穿现浇楼板;所述预制柱内主钢筋内呈对角线设置的两根钢筋作为预制柱内引下线;所述预制柱内主钢筋在现浇楼板顶面位置用螺栓连接有钢筋套筒,该钢筋套筒把上下钢筋连接成整体;所述预制柱底部附加导体为两根凹形圆钢结构,该预制柱底部附加导体一端分别焊接于预制柱内引下线底部,另一端贯穿出预制柱贴合现浇楼板顶面延伸一段距离;所述连接钢板预埋在现浇楼板上与预制柱底部附加导体端部对应的位置,该连 ...
