Friction and gravity energy dissipation type bridge anti-seismic check block and construction method thereof
The invention relates to the technical field of bridge earthquake prevention, in particular to a friction and gravity energy dissipation type bridge anti-seismic check block and a construction methodthereof. The friction and gravity energy dissipation type bridge anti-seismic check block comprises a steel bottom plate, a steel cover, a groove steel block, a small steel checkblock, a steel check block, a steel ball, a transverse spring, a vertical spring, a thick and heavy pulley, a steel corbel web plate, a steel corbel bottom plate, a steel corbel top plate, a steel corbel side plate, a steel corbel bolt, a steel baffle web plate, a steel baffle top plate, a steel baffle side plate and a steel baffle bolt. In the case of earthquake occurrence, earthquake energy is converted into pulley gravitational potential energy to achieve the effect of reducing the earthquake energy on a bridge; internal components generate friction force and consume earthquake energy during movement; meanwhile,earthquake energy can be buffered through the arrangement of the steel springs, so that the problem that the bridge body moves can be relieved, even the possibility of collision between the bridge bodies is reduced, the bridge can be well protected, and harm to the bridge when an earthquake occurs is reduced.
本发明涉及桥梁防震技术领域，尤其涉及一种摩擦和重力耗能型桥梁抗震挡块及其施工方法，包括钢底板、钢罩、凹槽钢块、小钢挡块、钢挡块、钢球、横弹簧、竖弹簧、厚重滑轮、钢牛腿腹板、钢牛腿底板、钢牛腿顶板、钢牛腿侧板、钢牛腿螺栓、钢挡板腹板、钢挡板顶板、钢挡板侧板、钢挡板螺栓。当发生地震时，本发明通过将地震能量转化为滑轮重力势能来达到减小地震能量对桥梁的作用，且内部构件在运动时产生摩擦力并消耗地震能量，同时各钢弹簧的设置能够缓冲地震能量，从而本发明能够缓解桥梁梁体发生移动的问题，甚至减小桥梁梁体之间发生碰撞的可能性，可以较好的保护桥梁，使地震发生时对桥梁产生的危害降低。
