Truss type replaceable energy dissipation coupling beam with friction energy dissipation support
The invention discloses a truss type replaceable energy dissipation coupling beam with a friction energy dissipation support. The truss type replaceable energy dissipation coupling beam comprises a truss type coupling beam body, a coupling beam end component and an embedded connecting steel plate. wherein the truss type coupling beam comprises a square steel tube upper chord, a square steel tube lower chord, hinged connecting pieces and friction energy dissipation supports, the hinged connecting pieces are fixedly connected to the two ends of the square steel tube upper chord and the square steel tube lower chord, and the two friction energy dissipation supports are connected with the hinged connecting pieces through pins to form diagonal web members in the truss type coupling beam, are in a cross shape and are not in contact, The embedded connecting steel plate is arranged in a wall body, the connecting beam end components are welded at the two ends of the square steel tube upper chord and the square steel tube lower chord, and the truss type connecting beam and the embedded connecting steel plate can be hinged through the connecting beam end components. According to the truss type replaceable energy dissipation coupling beam, shear deformation of a common coupling beam is converted into axial deformation of the friction energy dissipation supports, so that the friction energy dissipation support serves as a first anti-seismic defensive line, and after the friction energy dissipation support fails, the square steel tube upper chord and the square steel tube lower chord form a new coupling beam serving as a second defensive line.
本发明公开一种带摩擦耗能支撑的桁架型可更换消能连梁，包括桁架型连梁、连梁端部构件和预埋连接钢板；所述桁架型连梁包含方钢管上弦杆、方钢管下弦杆、铰接连接件和摩擦耗能支撑；铰接连接件固接于方钢管上弦杆和下弦杆的两端，两个摩擦耗能支撑通过销钉与铰接连接件相连，使之成为桁架型连梁中的斜腹杆，呈十字交叉形且无接触。预埋连接钢板设置于墙体内，连梁端部构件焊接于方钢管上弦杆和方钢管下弦杆的两端，桁架型连梁和预埋连接钢板可通过连梁端部构件铰接。本发明将一般连梁的剪切变形转化为摩擦耗能支撑的轴向变形，使得摩擦耗能支撑为第一道抗震防线，在摩擦耗能支撑失效后，方钢管上弦杆与方钢管下弦杆形成新的连梁，为第二道防线。
