Fabricated concrete frame beam-column self-resetting friction joint connecting structure and assembling method
The invention provides a fabricated concrete frame beam-column self-resetting friction joint connecting structure and an assembling method. Longitudinal friction connecting steel pieces of the connecting structure are installed on the upper portion and the lower portion of an embedded steel plate in a column, transverse friction connecting steel pieces are installed on the upper side and the lower side of the end of a prefabricated concrete beam, wherein the longitudinal friction connecting steel pieces and the transverse friction connecting steel pieces are connected through rotating shaft bolts at the junction of beam-column joints, and the inner and outer plate walls of a first arc-shaped friction steel plate and a second arc-shaped friction steel plate between the longitudinal friction connecting steel pieces and the transverse friction connecting steel pieces are in close contact along the arc-shaped boundary and are connected through sliding bolts, and the pre-tightening force applied to the rotating shaft bolts and the sliding bolts can effectively ensure the flexural rigidity of the joints, so that the joints are kept in an elastic state when the earthquake action is small. According to the connecting structure, the technical problems of how to effectively improve the energy dissipation capacity of the joints and how to reduce damage and destruction of the structure under the action of an earthquake to the maximum extent are solved, connection between the prefabricated concrete beam and the prefabricated concrete column is achieved, and the requirements in actual design and construction are met.
本发明提出一种装配式混凝土框架梁柱自复位摩擦节点连接结构及拼装方法，该连接结构纵向摩擦连接钢件安装在柱内预埋钢板的上下部，所述横向摩擦连接钢件安装在预制混凝土梁的端头上下侧，其中纵向摩擦连接钢件与横向摩擦连接钢件在梁柱节点交界处通过转轴螺栓相连，二者间的弧形摩擦钢板Ⅰ和弧形摩擦钢板Ⅱ内外板壁沿弧形边界紧密接触，并通过滑动螺栓相连，对转轴螺栓和滑动螺栓施加的预紧力能够有效保证节点的抗弯刚度，使节点在地震作用较小时保持弹性状态。本发明解决了如何有效提高节点的耗能能力，最大限度的降低结构在地震作用下的损伤和破坏的技术问题，本发明实现预制混凝土梁和预制混凝土柱间的连接，以满足实际设计与施工中的需要。
