Prefabricated bridge pier connection beam and construction method thereof
The invention discloses a prefabricated assembly type bridge pier connection beam and a construction method thereof. The connection beam is connected between two bridge pier columns. The connecting beam comprises a third steel plate, second steel plates are connected to the two ends of the third steel plate, the second steel plates are connected with I-shaped steel plates, and the I-shaped steel plates are arranged in the pier columns. A gap is reserved between the third steel plate and the second steel plate which are connected through a plurality of energy dissipation mechanisms. The energy dissipation mechanism comprises a sliding rail and a sliding block connected with the sliding rail in a sliding mode, and a steel column is arranged in the sliding block. The sliding rail is fixedly connected with one of the third steel plate and the second steel plate through the memory alloy column, a limiting hole is formed in the sliding rail, and the steel column penetrates through the limiting hole to be fixedly connected with the other one of the third steel plate and the second steel plate. After being stressed, the sliding blocks can freely move in the limiting holes of the sliding rails, movement deformation in any direction is converted into torsional deformation of the memory alloy columns, more energy can be absorbed, the sliding blocks can restore to the initial shape, and the resistance capacity of a structural system under complex stress is greatly improved.
本发明公开了一种预制装配式桥墩联系梁及其施工方法，该联系梁连接于两个桥墩柱之间；联系梁包括第三钢板，第三钢板的两端连接有第二钢板，第二钢板连接有工字形钢板，工字形钢板设置于桥墩柱的内部；第三钢板与第二钢板之间留有间隙且通过若干个耗能机构连接；耗能机构包括滑轨以及与滑轨滑动连接的滑块，滑块内设置有钢柱；滑轨通过记忆合金柱与第三钢板和第二钢板中的一个固定连接，滑轨开设有限位孔，钢柱穿过限位孔与第三钢板和第二钢板中的另一个固定连接。本发明滑块受力后可在滑轨的限位孔内任意移动，将任意方向的移动变形转变为记忆合金柱的扭转变形，能吸收更多能量，还能恢复成初始形状，极大提高了结构体系在复杂受力下的抵抗能力。
