Description

具有耗能作用的抗震无热桥墙板
技术领域
本发明属于建筑技术领域,特别是涉及一种具有耗能作用的抗震无热桥墙板。
背景技术
剪力墙又称抗风墙、抗震墙或者结构墙,用于在房屋或者构筑物中承受风荷载或地震作用所引起的水平荷载,剪力墙能够有效防止建筑结构受到剪切破坏。目前,全预制剪力墙结构预制化率虽然比较高,但剪力墙约束边缘构件内纵筋和箍筋配置较多,预制拼装接缝的连接构造比较复杂、施工难度较大,而且可能引起混凝土材料性能劣化的因素较多,特别是沿海暖湿气流的侵蚀作用下,混凝土结构的老化现象非常严重。建筑物结构耐久性损伤问题日益突出,长期维持混凝土原有性能的能力变得弱化,混凝土开裂剥离现象普遍出现。同时,地震灾害具有突发性和毁灭性,地震发生时,地面振动引起结构的地震反应。为了避免上述灾害的发生,人们必须对结构体系的地震反应进行控制,并消除结构体系的“放大器”作用,保护主体结构及构件在强震或大风中免遭破坏,行业内采用增加混凝土墙体厚度的方式来改善上述状况,但这样不仅增大了混凝土用量,增加施工强度和成本,而且关键是,地震力是与墙体的自重成正比的,重量随着厚度增大后,地震产生的水平剪力也增大了,故墙体的抗水平剪力的效果即水平承载力仍然不理想,传统剪力墙的边缘构件存在配筋偏大的问题,在地震荷载作用下剪力墙的延性不足,耗能能力较差,其设计、施工均较复杂,为此,有必要针对现有建筑存在的受力性能差、抗震性能差的缺点进行工业化系统性的研发,使我国建筑产业真正实现全过程的绿色、可循环、可持续。

进一步地,所述的内嵌低屈服点耗能钢板(1)优先采用低屈服点钢板08FA钢制作而成。
进一步地,所述的FRP复合材料管(7)优选纤维增强复合材料GFRP材料制作而成。
