Fabricated concrete beam column energy dissipation connecting key
The invention discloses a fabricated concrete beam column energy dissipation connecting key. The energy dissipation connecting key comprises a first end plate, the first end plate is fixedly arrangedon a concrete column, and a second end plate is fixedly arranged on a concrete beam; one end of a first hinge plate is fixedly connected with the first end plate, the other end of the first hinge plate is hinged to one end of a second hinge plate, the other end of the second hinge plate is fixedly connected with the second end plate, and hinge shafts of the first hinge plate and the second hinge plate are horizontally arranged; two energy dissipation plates are vertically arranged between the first end plate and the second end plate in parallel and symmetrically arranged on the two sides of the first hinge plate and the second hinge plate; and the two ends of each energy dissipation plate are detachably and fixedly connected with the first hinge plate and the second hinge plate correspondingly. According to the energy dissipation connecting key, through arranging the two hinged plates which are hinged to each other, a relatively weak area is formed at the beam end of a beam-column joint, controllability of a beam end shaping hinge is achieved, and brittle failure of a beam-column joint area is avoided; and through arranging the energy dissipation plates, the energy dissipation plates can effectively absorb seismic energy, and the overall seismic performance of the structure is improved.
本发明公开了一种装配式混凝土梁柱耗能连接键，包括第一端板，第一端板固定设置在混凝土柱上，第二端板固定设置在混凝土梁上；第一铰接板的一端与第一端板固定连接，另一端与第二铰接板的一端铰接，第二铰接板的另一端与第二端板固定连接，第一铰接板与第二铰接板的铰接轴水平设置；两个耗能板竖向平行设置在第一与第二端板之间，且对称设置在第一及第二铰接板的两侧；耗能板的两端分别第一铰接板及第二铰接板可拆卸固定连接；本发明通过设置两个相互铰接连接的铰接板，其在梁柱节点的梁端处形成相对薄弱区，实现了梁端塑形铰的可控性，避免了梁柱节点区域的脆性破坏；通过设置耗能板，耗能板能够有效吸收地震能量，提高了结构的整体抗震性能。
