Metal energy dissipation type bridge anti-falling beam device and mounting method thereof
The invention discloses a metal energy dissipation type bridge anti-beam-falling device and a mounting method thereof. The metal energy dissipation type bridge anti-beam-falling device comprises core square steel pipes arranged on main beams on the left side and the right side, metal sliding blocks, springs, spring baffles, pin shafts, reserved bolt hole connecting pieces, first connecting bolts, second connecting bolts. and an upper arc-shaped metal energy consumption plate and a lower arc-shaped metal energy consumption plate which are arranged in the middle. The metal sliding blocks are sleeved outside the center positions of the core square steel pipes, two springs are respectively sleeved outside two sides of the metal sliding blocks, the other ends of the springs are contacted with spring limiting plates, and the limiting plates are fixed on the core steel pipes. The two ends of the upper arc-shaped metal energy consumption plate are welded to the upper pin shafts of the sliding parts on the left side and the right side correspondingly. In a normal use state, the telescopic deformation of the main beam caused by temperature change is adapted through the sliding of the metal sliding blocks and the elastic deformation of the metal springs; the mechanical property of a metal material is fully exerted, the energy dissipation capacity is high and stable, installation is easy, and replacement is easy after an earthquake.
本发明公开了一种金属耗能型桥梁防落梁装置及其安装方法，包括布置在左右两侧主梁上的核芯方钢管、金属滑块、弹簧、弹簧挡板、销轴、预留螺栓孔连接件、第一连接螺栓、第二连接螺栓，以及布置在中间的上弧形金属耗能板、下弧形金属耗能板。金属滑块外套在核芯方钢管的中心位置，金属滑块的两侧分别外套两个弹簧，弹簧的另一端与弹簧限位板接触，限位板固定在核芯钢管上。将上弧形金属耗能板的两端分别焊接在左右两侧滑动部件的上部销轴上。本发明在正常使用状态下，通过金属滑块的滑动和金属弹簧的弹性变形来适应温度变化造成的主梁伸缩变形；本发明充分的发挥金属材料力学性能，耗能能力强且稳定，并且安装简单，震后易更换。
