Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-4, a new shock absorbing system with synergy between the main structure and the supporting structure, including the main structure composed of the basement and the superstructure outside the basement, and the surrounding of the basement is provided with supporting structures 4 , the basement includes the basement exterior wall 2 poured around and the basement floor slab 1 at the connection, the bottom basement is poured with a basement floor 3 connected to the soil layer, and multiple groups of energy-dissipating shock-absorbing devices are arranged between the main structure and the supporting structure 4, The support structure 4 is connected with the basement of the main structure through an energy-dissipating shock-absorbing device to realize three-dimensional shock-absorbing of the main structure. The energy of the structure reduces the seismic (vibration) response of the structure.

The energy-dissipating shock-absorbing device includes the left end plate 5 of the shock-absorbing device, the shock-absorbing device 6 and the right end plate 7 of the shock-absorbing device. The outer wall of the nearby support structure 4 is provided with a right end plate 7 of the shock absorber, and the left end plate 5 of the shock absorber is symmetrical with the right end plate 7 of the shock absorber, and the left end plate 5 of the shock absorber and the right end plate 7 of the shock absorber are fixed by A shock absorber 6 is connected, and the shock absorber 6 is located at the midpoint of the left end plate 5 of the shock absorber and the right end plate 7 of the shock absorber.

The basement floor slab 1 at the basement floor 1 of the basement floor slab 1 of the installation position of damper left end plate 5, damper 6 and damper right end plate 7 of damper.

The left end plate 5 of the shock absorbing device is a concrete end plate or steel end plate made of holes reserved during the pouring of the supporting structure 4. The specific structural size depends on the size of the shock absorbing device and the gap between the main structure and the supporting structure 4 Wait for the design, the reserved holes of the shock absorber are connected with the left and right end plates by bolts, so that the damage of the shock absorber can be easily replaced, and the connection structure is stable and reliable, and can be installed flexibly, which is convenient for installation in actual projects and does not affect the function of the building. . If a self-restoring damping device is used, connections such as welding can be used to realize a more reliable connection structure of "replacement-free" damping device 6 . The right end plate 7 of the shock-absorbing device is poured and molded after reserving reinforcement hole positions etc. while the basement exterior wall 2, column, and floor slab construction of the main structure, and the connection structure etc. are consistent with the left end plate.

The shock-absorbing device 6 in the energy-dissipating shock-absorbing device can be a support, a damper, etc., including but not limited to the forms listed above, which are used to consume the energy input to the structure by earthquakes or other vibrations, reduce the vibration response of the structure, and reduce the energy consumption of the structure. Energy damping devices are often used inside or between building structures, but have not been applied between the main structure and the supporting structure to reduce the vibration response of the main structure. Energy-dissipating shock absorbers can be used for passive, active or hybrid control of structures, etc. Its working mechanism is that under the action of small earthquake/weak wind vibration, the relative deformation between the support structure 4 and the main structure is small, and the damper provides a certain additional stiffness of the main structure; under the action of large earthquake/strong wind vibration, the support structure 4 and the main structure The relative deformation between the two parts is relatively large, and the force transmission belt is damaged. The damper dissipates the external input energy through tension, compression, shearing, bending and other deformations, thereby effectively reducing the seismic response of the main structure;

When the energy-dissipating shock-absorbing device is a damper, it can be a displacement type or a velocity-type damper, such as a three-dimensional viscoelastic damper, a viscous damper, a metal damper, etc. , subway, vehicle vibration, etc.) input energy into the structure, to achieve the effect of energy dissipation and shock absorption, and reduce the vibration response of the structure.

For example, when the shock absorber 6 in the energy dissipation shock absorber is a viscous damper, the viscous damper is composed of a piston, a piston rod and a cylinder storing viscous liquid, and is often used to reduce the wind vibration or wind vibration of high-rise building structures and bridges. Anti-seismic, anti-seismic transformation of building structures, anti-seismic of industrial pipeline equipment, military industry and other fields, it is a kind of shock absorber that is widely used in various types of shock absorbers at present, and it is a non-stiffness, speed-dependent damper. The working mechanism of the viscous fluid damper is that under the earthquake or other external excitations, the piston rod moves in the cylinder, forcing the pressurized fluid to pass through the pores or gaps, thereby generating damping force, which plays the role of energy consumption and shock absorption. The most important contribution of the viscous damper device is to play a three-dimensional shock-absorbing and energy-dissipating effect on the main structure through the relative displacement of the main structure and the support structure 4 under the earthquake action.

For example, the shock absorber 6 in the energy dissipation shock absorber is composed of a three-dimensional viscoelastic damper. When the damper has space energy dissipation capacity, it can not only provide axial bearing capacity, but also realize hysteresis in the direction perpendicular to the axis. Energy dissipation, energy dissipation can also be carried out under small vibration conditions, and it can be used for both seismic and wind vibration control of the structure, avoiding the problem of how to match the initial stiffness of other energy dissipation devices with the lateral stiffness of the structure . Its working mechanism When the main structure and the supporting structure 4 undergo relative displacement, the support will be driven by the relative displacement between the main structure and the surrounding structure to consume hysteretic energy, dissipate the energy input to the structure by the earthquake, and reduce the energy of the main structure. earthquake response.

The energy dissipation damping device in this device can be arranged in multiple positions between the supporting structure 4 and the main structure. According to the needs of vibration analysis, the energy-dissipating shock absorbing device is arranged at the position where the relative displacement or relative velocity of the main structure and supporting structure 4 is relatively large, which can effectively reduce the vibration response of the structure.

Working principle: Under the action of small earthquake/weak wind vibration, the relative deformation between the support structure 4 and the main structure is small, and the damper provides a certain additional stiffness of the main structure; under the action of large earthquake/strong wind vibration, the distance between the support structure 4 and the main structure The relative deformation is relatively large, and the force transmission belt is damaged. The damper uses deformation such as tension and compression, shearing, and bending to dissipate the external input energy, thereby effectively reducing the seismic response of the main structure.

The new damping system provided by the utility model maximizes the utilization rate of the supporting structure, and realizes the synergy between the main structure and the supporting structure through effective design, and the form of the energy-consuming damping device is changeable, suitable for Strong resistance, broad application prospects and good shock absorption effect.
