Fabricated concrete frame beam column self-reset joint connection structure and splicing method
The invention provides a beam column self-reset joint connection structure in fabricated concrete frame structures and a splicing method. A pre-fabricated reinforced concrete beam and a pre-fabricatedreinforced concrete column are perpendicularly connected through I-shaped steel plate keys which are arranged in parallel in the vertical direction. The connection ends of the pre-fabricated reinforced concrete beam and the pre-fabricated reinforced concrete column are both provided with clamping groove type steel plate embedded parts. The two I-shaped steel plate keys are connected with clampinggrooves in the upper side and the lower side of the clamping groove type steel plate embedded parts. A plurality of pre-stress tendons horizontally penetrate through the pre-fabricated reinforced concrete beam and penetrate out of the pre-fabricated reinforced concrete column. Each pre-stress tendon anchorage device is screwed at the extending end of the corresponding pre-stress tendon and is fixed. Energy-dissipating dampers are installed on the two sides of each I-shaped steel plate key. The effect of effectively improving the energy dissipation capacity of a joint is achieved, and deformation damage of pre-fabricated components after earthquakes is reduced to the greatest extent. The beam-column joint can dissipate a large amount of energy under the action of earthquakes, and can resetto the original state after the earthquakes.
本发明提出一种装配式混凝土框架结构中梁柱自复位节点连接结构及拼装方法，该结构的预制钢筋混凝土梁和预制钢筋混凝土柱通过上下平行设置的工字型钢板键垂直连接，预制钢筋混凝土梁和预制钢筋混凝土柱的连接端均安装有卡槽式钢板预埋件，两个工字型钢板键与卡槽式钢板预埋件的上下两侧的卡槽连接，若干预应力筋横穿预制钢筋混凝土梁，并穿出预制钢筋混凝土柱，每个预应力筋锚具对应旋在预应力筋的伸出端进行固定，工字型钢板键的两侧安装有耗能阻尼器。解决了如何有效提高节点的耗能能力，最大限度的降低预制构件在震后的变形破坏的问题。本发明装配后的梁柱节点在地震作用下能够耗散大量能量，地震后能够恢复到原来的初始状态。
