The invention provides a filling wall to prevent out-of-plane collapse, including frame columns, frame beams and filling walls. Tension bars are welded on the external surface of the embedded steel plate in the frame column, and the limit slides are welded on the surface of the embedded steel plate to form a limit system. The invention provides a filling wall to prevent out-of-plane collapse by welding anti-collapse round steel on the embedded steel plate on the surface of the frame column and extending into the filling wall, which limits the displacement of the filling wall in the out-of-plane direction, prevents the planar collapse of the filling wall under the action of large earthquakes and avoids casualties, and has energy absorption effect by filling the gap between the filling wall and the frame column. Elastic-plastic material can make the filling wall and frame column completely detached, avoid the formation of short columns and absorb certain seismic energy; when pouring frame column concrete, the steel plate is embedded in the corresponding position with the filling wall tie bar, and after demolition, the tie bar of the filling wall is welded on the external surface of the pre-embedded steel plate, which is easy to construct, avoids the planting of steel bar, ensures the performance and does not need to be on the formwork. Open the hole and reuse it.
【技术实现步骤摘要】
一种防止平面外倒塌的填充墙
本专利技术涉及建筑领域,特别涉及一种防止平面外倒塌的填充墙。
技术介绍
框架结构是当今应用最为广泛的建筑结构形式之一,框架是承重和抗侧力主体,辅以填充墙对房屋进行分割和维护。我国是一个地震多发的国家,而当填充墙与框架主体完全脱开或连接不牢固时,填充墙在地震中极易发生破坏,倒塌甚至平面外甩出。为增加填充墙整体性,《砌体结构设计规范》规定在填充墙灰缝中每隔一定距离放置拉结筋并锚固在端部框架柱内。目前实际施工中,填充墙中的拉结筋在框架柱中的处理办法主要有两种:一是在浇筑框架柱混凝土时,在框架柱中预留拉结筋,这种方法由于需要在模板上开洞使拉结筋通过,破坏模板,并且施工工序复杂,实际使用较少;二是如公告号为CN203742020U的专利“一种新型框架墙结构”提出的通过在框架外表面植设钢筋的方式,该方法实际施工中植筋深度很难得到保证、植筋粘合剂随着时间的推移性能降低等,故目前的措施很难避免大震时填充墙平面外倒塌破坏。并且通过汶川地震和青海玉树地震震害调查发现,上述方案中仅通过拉结筋的办法在强度较大的地震时其增加墙体稳定性的效果实际上非常有限。
