Beam falling prevention device with friction energy dissipation and self-resetting functions
The invention discloses a beam falling prevention device with friction energy dissipation and self-resetting functions. The beam falling prevention device comprises a metal shell, a high-strength bolt, a reset spring, a variable-friction high-damping rubber pad, a U-shaped energy dissipation counter-force plate, a limiting prestress device, a guiding pulley device, a pre-tightening bolt and a limiting anchorage device. One end of the reset spring is welded with the U-shaped energy dissipation counter-force plate, and the other end of the reset spring is welded with the metal shell to form a whole; one end of the limiting prestress device penetrates through the metal shell and the U-shaped energy dissipation counter-force plate through a hole channel and is connected with the U-shaped energy dissipation counter-force plate through the limiting anchorage device. The guiding pulley device is connected with a bridge abutment through the high-strength bolt, and the limiting prestress device is steered through the guiding pulley device, is connected with a main beam on the upper portion of a bridge through the limiting anchorage device and exerts certain pretightening force to balance the reset spring. The device has the advantages of being convenient to construct, simple in structure, clear in stress, low in manufacturing cost, convenient to inspect and maintain and the like, and the device can be rapidly replaced after being damaged in an earthquake.
本发明公开了一种具有摩擦耗能和自复位功能的防落梁装置，包括金属外壳、高强螺栓、复位弹簧、变摩擦高阻尼橡胶垫、U形耗能反力板、限位预应力装置、导向滑轮装置、预紧螺栓、限位锚具。复位弹簧的一端与U形耗能反力板焊接，另一端与金属外壳焊接形成一整体；限位预应力装置一端通过孔道穿过金属外壳与U形耗能反力板，并通过限位锚具与U形耗能反力板连接；导向滑轮装置通过高强螺栓与桥台相连，限位预应力装置通过导向滑轮装置转向并通过限位锚具与桥梁上部主梁连接，并施加一定的预紧力平衡复位弹簧。本发明具有施工方便、结构简单、受力清晰、造价低廉、检查维修方便等优点，且在地震中发生损伤后可实现快速更换的功能。
