Referring to fig. 1 or 2, four edges of each rectangular base plate 1 are connected with rectangular baffle plates 2 through bolts, every four rectangular baffle plates 2 are sequentially connected and form a rectangular cavity with the connected rectangular base plate 1, and a plurality of tumbler balls 3 are placed in the rectangular cavity.
Referring to fig. 3, the tumbler ball 3 is spherical, the cavity 5 is formed in the tumbler ball 3, the cavity 5 is spherical, and the center of the cavity is located right above the center of the tumbler ball 3, so that the center of gravity of the tumbler ball 3 is lower than the center of the tumbler ball, and a tumbler working mechanism is formed.
The cavity 5 is internally provided with a filler, the volume of the filler is less than that of the cavity 5, and the filler is a granular substance or a viscous liquid. When the filling material in the cavity 5 is viscous liquid, the inner wall of the cavity 5 is in a honeycomb shape or a plurality of layers of metal nets are arranged in the cavity 5.
The top of the tumbler sphere 3 is provided with a threaded hole penetrating through the inner side and the outer side of the cavity 5, fillers are filled in from the threaded hole, and then the bolt 4 is screwed into the threaded hole to be sealed.
In the embodiment, a bulk material, such as a steel ball, a glass ball, a concrete ball, a shot, ceramsite sand or sand, is added into the cavity inside the tumbler sphere 3, the motion of the bulk material has hysteresis under the action of an earthquake, and the hysteresis of the bulk material can enable collision and friction between fillers of the bulk material and between the bulk material and the tumbler device when the tumbler sphere moves, so that more energy is dissipated.
If viscous liquid such as silicon oil is added into the cavity inside the tumbler sphere, the viscous liquid such as the silicon oil has hysteresis under the action of an earthquake, and when the tumbler device moves, the hysteresis of the viscous liquid such as the silicon oil can enable collision and friction between the viscous liquid such as the silicon oil and the tumbler device, so that the damping performance of the system is improved, and more energy is dissipated.
The rectangular baffle 2 is mainly used for preventing the tumbler sphere 3 from generating excessive impact force on the internal structure or non-structural components of the building during earthquake. When earthquake occurs, the rectangular chassis 1 designed by the invention moves synchronously with the floor, and the tumbler ball 3 generates amplitude limiting swing due to self inertia, thereby forming a working mechanism of the shock-absorbing tuned mass damper. When the tumbler ball 3 swings, the internal filler moves relative to the tumbler cavity, the damping characteristic of the tuned mass damper is improved, and the damping effect of the damper is improved. An effective means is provided for lightening the earthquake disaster of the structure and improving the earthquake safety of the structure.
