Rotatable self-resetting joint connecting structure for fabricated concrete beam column and splicing method
The invention provides a rotatable self-resetting joint connecting structure for a fabricated concrete beam column and a splicing method. A prefabricated reinforced concrete beam and a prefabricated reinforced concrete column of the structure are vertically connected through the matching of U-shaped connecting steel plate keys and connecting steel plate keys shaped like a Chinese character 'shan'.The U-shaped connecting steel plate keys and the connecting steel plate keys shaped like the Chinese character 'shan' are oppositely arranged and further in matched connection through rotatable positioning bolt sets, and relative rotation can be achieved. A plurality of prestressed tendons transversely penetrate through the prefabricated reinforced concrete beam, the U-shaped connecting steel plate keys and the connecting steel plate keys shaped like the Chinese character 'shan' in sequence, finally penetrate out of the prefabricated reinforced concrete column and are further fixed through prestressed tendon anchorage devices. The problems that dry-type connecting joints are poor in energy consumption and can be seriously deformed under the strong earthquake effect are effectively solved.The prefabricated reinforced concrete beam and the prefabricated reinforced concrete column can be connected, the needs in actual design and construction are met, pretightening force applied to high-strength bolts can effectively guarantee the flexural rigidity of the joints, and the joints can be kept in an elastic state when the action of earthquakes is small.
本发明提出一种装配式混凝土梁柱可转动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U型连接钢板键和山字形连接钢板键的配合垂直连接，U型连接钢板键与山字形连接钢板键相对设置且通过转动定位螺栓组配合连接，能够实现相对转动，若干预应力筋依次横穿预制钢筋混凝土梁、U型连接钢板键和山字形连接钢板键，最后从预制钢筋混凝土柱穿出，并通过预应力筋锚具固定。解决了如何有效解决干式连接节点耗能不佳，且在强震作用下变形严重的问题，实现预制混凝土梁和预制钢筋混凝土柱间连接，以满足实际设计与施工中的需要，对高强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。
