Semi-rigid energy dissipation connecting structure for prefabricated externally-hung wallboards
The invention relates to a semi-rigid energy-consuming connecting structure for a prefabricated external wall panel. The semi-rigid energy-consuming connecting structure comprises two first nodes which are fixedly connected with the lower part of the prefabricated external wall panel to a main body structure, and two second nodes which are connected with the upper part of the prefabricated external wall panel to the main body structure; the second joint comprises a second wallboard embedded part, a second main body structure embedded part, a U-shaped damper and a friction energy dissipation mechanism; the friction energy dissipation mechanism comprises a first friction plate fixedly arranged on the outer side of the second wallboard embedded part and a second friction plate fixedly arranged on the outer side of the second main body structure embedded part, a through hole is formed in the middle of the first friction plate, and a second long hole extending vertically is formed in the middle of the second friction plate. The second friction plate is fixedly attached to the side face of the first friction plate. The first friction plate is composed of a bottom plate made of steel and an energy consumption plate made of brass, and a plurality of fixing strips which are vertically distributed and are in a comb tooth shape are arranged on the outer side face of the bottom plate. Due to the fact that the energy dissipation piece of the first friction piece is made of brass, earthquake energy can be continuously absorbed.
本发明涉及一种预制外挂墙板半刚性耗能连接结构，包括两个第一节点固定连接预制外挂墙板的下部于主体结构，两个第二节点连接预制外挂墙板的上部于主体结构；第二节点包括第二墙板预埋件、第二主体结构预埋件、U形阻尼器以及摩擦耗能机构；其中摩擦耗能机构包括固定设置于第二墙板预埋件外侧部的第一摩擦片、固定设置于第二主体结构预埋件外侧部的第二摩擦片，第一摩擦片中部设置有通孔，第二摩擦片中部设置有竖向延伸的第二长孔，第二磨擦片固定贴合在第一摩擦片侧面；第一摩擦片由钢材质的底片以及黄铜材质的耗能片组成并且底片外侧面具有若干竖向分布且呈梳齿状的固定条。由于第一摩擦片的耗能片是黄铜材质，能持续吸收地震能量。
