Energy consumption type multidirectional limiting bridge anti-seismic device with steel springs
The invention discloses an energy dissipation type multidirectional limiting bridge anti-seismic device with steel springs. The device comprises steel corbels, limiting parts, the steel springs, sliding blocks and connecting steel columns. The steel corbels are fixed to the side face of the top of the pier near the movable support, the limiting parts are fixed to the bottom of the main beam and the steel corbels, and the two limiting parts are vertically aligned and are symmetrical in position. The limiting part comprises a fixed plate, a square steel check block and anti-drawing steel check blocks on the two sides. The sliding block is located in the limiting part. Two ends of the connecting steel column are respectively connected with the upper and lower sliding blocks; the middle cylindrical part is made of energy-consuming low-yield-strength steel, earthquake energy can be consumed by means of energy generated by plastic deformation of the middle cylindrical part, one end of the steel spring is fixed to the inner walls of the vertical sections of the anti-drawing steel check blocks on the two sides, the other end of the steel spring is connected with the sliding block, and after an earthquake is finished, the device can be reset to a certain degree through the restoring force effect. The device is simple in structure, good in anti-seismic effect and capable of realizing three-way limiting.
本发明公开了一种具有钢弹簧的耗能型多向限位桥梁抗震装置，包括钢牛腿、限位件、钢弹簧、滑块以及连接钢柱；钢牛腿固定在活动支座附近的桥墩顶部的侧面，限位件固定在主梁底部和钢牛腿上，两个限位件上下对齐设置且位置对称；限位件包括固定板、方形钢挡块和两侧抗拉拔钢挡块，滑块位于限位件内部，连接钢柱的两端分别与上下两个滑块相连，其中间圆柱形部分的材料为耗能型低屈服强度钢，可依靠其塑性变形产生的能量消耗地震能量，钢弹簧一端固定在两侧抗拉拔钢挡块竖直段内壁上，另一端与滑块相连，在地震结束后可通过其恢复力作用使得装置实现一定的复位。该装置构造简单，抗震效果好，能三向限位。
