Self-resetting energy-dissipation anti-pulling connecting piece
In order to solve the problems that an existing anti-pulling piece is prone to causing side column tearing damage and poor in anti-seismic performance, three anti-seismic defense lines are innovatively provided around small earthquakes, medium earthquakes and large earthquakes, the energy absorption and energy dissipation capacity is improved, side column damage caused by sudden rigidity change of the anti-pulling connecting piece in earthquakes is avoided from the stress mechanism, and the anti-pulling connecting piece is domestically pioneered. According to the self-resetting energy dissipation anti-pulling connecting piece, a vertical connecting plate and a horizontal connecting plate are connected through a self-resetting energy dissipation shaft rod piece, and the horizontal connecting plate is provided with a limiting step and is filled with an energy absorption damping block. When an earthquake acts, the anti-pulling piece is stressed, the vertical connecting plate and the horizontal connecting plate rotate relatively along with the anti-pulling piece, the limiting step always ensures that the rotating angle is within the inter-layer displacement angle range, the self-resetting energy dissipation shaft rod and the energy absorption damping block deform, and therefore earthquake energy is continuously absorbed and dissipated, meanwhile, the energy dissipation steel belt is arranged to absorb most of energy, and the energy dissipation effect is improved. Instant collapse of the building caused by a large earthquake is prevented, and three earthquake-proof defense lines are formed.
本发明针对现有抗拔件易导致边柱撕裂破坏、抗震性能较差的问题，围绕小震、中震、大震创新提出三道抗震防线，改善吸能、耗能能力，从受力机理上避免了在地震中因为抗拔连接件刚度突变所导致的边柱破坏，属于国内首创。本发明给出一种自复位耗能抗拔连接件，其中竖向连接板和水平连接板通过自复位耗能轴杆件连接，在水平连接板设置限位台阶并填充吸能阻尼块。当地震作用时，抗拔件受力，竖向连接板和水平连接板随之发生相对旋转，而限位台阶始终保证旋转的角度在层间位移角范围内，使得自复位耗能轴杆及吸能阻尼块变形，从而不断吸收、耗散地震能量，同时设置耗能钢带吸收绝大部分能量，防止大震导致的建筑物瞬间倒塌，形成三道抗震防线。
