Anti-disengaging self-resetting anti-overturning device for support
The invention relates to the technical field of shock absorption and isolation of engineering structures, and provides a support anti-disengaging self-resetting anti-overturning device which comprises an upper supporting part and a lower supporting part, the upper supporting part comprises a friction box, a friction block, a connecting rod, a first resetting rod and a second resetting rod, and the lower supporting part comprises a sliding frame, a third resetting rod, a sliding block and a universal transmission assembly. Multi-directional displacement of the structure under the earthquake action is decomposed and allocated through the upper branch part and the lower branch part and is borne by the upper branch part and the lower branch part respectively, a loose and coupled working mechanism is formed, the vertical tensile capacity of the support is improved while normal horizontal rotation of the support is not affected, and the service life of the support is prolonged. Different from a traditional rigid tensile mode, disengaging separation between the structure and the support is reduced, reciprocating energy consumption and post-earthquake resetting are achieved through a first resetting rod, a second resetting rod and a third resetting rod, energy is dissipated again through linkage reciprocating sliding of a friction block and a friction box and linkage reciprocating sliding of a sliding block and a sliding frame, the overall response of the structure is controlled, and the service life of the structure is prolonged. And the safety and reliability of the structure are ensured.
本发明涉及工程结构减隔震技术领域，本发明提供了一种支座防脱空自复位抗倾覆装置，包括上支部和下支部，上支部包括摩擦盒、摩擦块、连接杆、第一复位杆和第二复位杆，下支部包括滑移架、第三复位杆、滑移块和万向传动组件，地震作用下结构的多向位移通过上支部和下支部实现分解与调配，并由上支部和下支部分别承担，形成松散且耦合的工作机制，在不影响支座正常平转的同时，提高了支座的竖向抗拉能力，区别于传统刚性抗拉模式的同时减少了结构与支座间脱空分离，通过第一复位杆、第二复位杆和第三复位杆实现往复耗能及震后复位，摩擦块与摩擦盒以及滑移块与滑移架的联动往复滑移再次耗散能量，控制了结构的整体响应，确保了结构的安全可靠性。
