Fabricated concrete beam column sliding self-resetting joint connecting structure and splicing method
The invention provides a fabricated concrete beam column sliding self-resetting joint connecting structure and a splicing method. A pre-fabricated reinforced concrete beam is perpendicularly connectedwith a pre-fabricated reinforced concrete column through U-shaped steel plate embedded parts and E-shaped steel plate embedded parts. The U-shaped steel plate embedded parts and the E-shaped steel plate embedded parts are arranged oppositely and matched and connected through sliding positioning bolt units, and relative sliding can be achieved. A plurality of prestress tendons sequentially and horizontally penetrate through the pre-fabricated reinforced concrete beam, the U-shaped steel plate embedded parts and the E-shaped steel plate embedded parts, and finally penetrate out of the pre-fabricated reinforced concrete column. The extending ends of the prestress tendons are fixed through prestress tendon anchorage devices. The effect of effectively improving the energy dissipation capacityof a joint is achieved, and deformation and damage of the structure under the action of earthquakes are reduced to the greatest extent. By means of the structure and the method, the connection betweenthe pre-fabricated reinforced concrete beam and the pre-fabricated reinforced concrete column is achieved, requirements in actual design and construction are met, the structure can maintain large resistant-lateral rigidity, and operation is easy and convenient.
本发明提出一种装配式混凝土梁柱可滑动自复位节点连接结构及拼装方法，该结构预制钢筋混凝土梁和预制钢筋混凝土柱通过U型钢板预埋件与山字型钢板预埋件垂直连接，U型钢板预埋件与山字型钢板预埋件相对设置且通过滑动定位螺栓组配合连接，能够实现相对滑动，若干预应力筋依次横穿预制钢筋混凝土梁、U型钢板预埋件和山字型钢板预埋件，最后从预制钢筋混凝土柱穿出，通过预应力筋锚具对预应力筋的伸出端进行固定。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问题。本发明实现了预制钢筋混凝土梁和预制钢筋混凝土柱间的连接，以满足实际设计与施工中的需要，结构整体保持较大的抗侧刚度，操作简单方便。
