The invention mainly comprises the following components: the device comprises an H-shaped steel column, an upper end L-shaped stopper, a lower end L-shaped stopper, an H-shaped steel beam, a steel sleeve plate, a prepressing disc spring, a telescopic rod, a reinforcing plate, an H-shaped steel column stiffening rib, a friction energy dissipation system and the like. When the self-resetting friction energy-consumption steel frame node based on the pre-pressed disc spring is acted by an earthquake force, the H-shaped steel beam and the H-shaped steel column rotate relatively. The self-resetting principle and the energy consumption principle of the invention are explained by taking the clockwise rotation of the H-shaped steel beam as an example.
1. A self-resetting principle;
when an earthquake occurs, the H-shaped steel beam drives the upper end L-shaped stopper and the lower end L-shaped stopper to rotate clockwise, the first pre-pressing disc spring at the upper part extends, and the pressure in the disc spring is reduced; and the second pre-pressing disc spring at the lower part is compressed, and the pressure in the disc spring is increased.
After an earthquake, the pressure of the second pre-pressing disc spring at the lower part is greater than that of the first pre-pressing disc spring at the upper part, so that the restoring force provided by the second pre-pressing disc spring at the lower part can push the L-shaped stopper at the lower end and the H-shaped steel beam to rotate anticlockwise until the initial position is restored. Thus, the self-reset function of the present invention is realized.
2. The energy consumption principle;
the energy dissipation capability of the present invention is provided by the sliding friction between the friction plates and the friction plates.
During earthquake, the H-shaped steel beam drives the friction plate to rotate clockwise, and the friction plate which is fixed relatively slide along the direction of the U-shaped hole groove of the friction plate.
After an earthquake, along with the self-resetting process of the steel frame node, the H-shaped steel beam drives the friction plate to rotate counterclockwise and also slides relative to the friction plate which is relatively fixed along the direction of the U-shaped hole groove of the friction plate.
No matter during or after an earthquake, sliding friction action exists between the friction plate and the friction plate, so that energy input by the earthquake can be converted into heat energy by using a solid friction mechanism to be dissipated, and the effect of protecting the steel frame joint is realized.
When the H-shaped steel beam rotates anticlockwise, the self-resetting principle and the energy consumption principle are the same.
The disc spring is a disc-shaped sheet spring stamped from a steel plate, has small volume, large bearing capacity, uniform pressurization and strong buffering and damping capacity, and can bear load with large variation range under the condition of small deformation. The prepressing disc spring formed after applying a certain prepressing force on the steel frame node has strong restoring force, and can help the steel frame node realize self-resetting after the steel frame node is vibrated. By adopting a friction energy dissipation mechanism in the node area, the earthquake input capacity can be effectively dissipated, and the earthquake protection of the steel frame node and even the steel frame structure system is realized.
In conclusion, the self-resetting friction energy-consumption steel frame node based on the pre-pressed disc spring can effectively dissipate energy input by an earthquake when the earthquake occurs, and achieves anti-seismic protection on the steel frame node and even a steel frame structure system; simultaneously, the self-reset function is realized through the restoring force provided by the pre-pressed disc spring after the earthquake, so that the earthquake-resistant defense area has a good application prospect.
