Abstract
Description
Technical Field
[0001] This utility model relates to the field of building structures, and in particular to a sliding base for building structures. Background Technology
[0002] Traditional building structures, especially those located in earthquake zones or areas with strong winds, often face horizontal and vertical vibrations caused by earthquakes, wind loads, equipment vibrations, and temperature changes. Fixed foundations can directly transfer this harmful energy to the superstructure, leading to structural damage or even collapse. Common seismic isolation measures, such as rubber bearings or friction pendulum isolators, are mainly effective against horizontal seismic forces and have limited effectiveness in suppressing vertical vibrations. They also have limitations such as weak recovery capacity, poor tensile strength, susceptibility to aging, and high cost. Their stability in dealing with high-frequency, low-amplitude vibrations (such as wind-induced vibrations or equipment vibrations) and under long-term loads needs improvement. In particular, for important building structures that require efficient isolation of both horizontal and vertical vibrations, as well as strong recovery capacity, high load-bearing capacity, and long-term stability, existing technical solutions often fail to fully meet the requirements.
[0003] Therefore, a sliding base for building structures is being developed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of existing devices, this utility model provides a sliding base for building structures.
[0005] The technical solution of this utility model is: a sliding base for a building structure, including a first mounting base, with second mounting bases provided on both the left and right sides of the first mounting base, a connecting block slidably disposed inside the first mounting base, a first mounting plate disposed on the top of the connecting block, a first damper disposed on both the left and right sides of the first mounting base, a first spring disposed on each of the first dampers, a contact block disposed inside each of the first dampers, and each contact block being able to contact the connecting block, and a connecting plate disposed on the top of each of the first mounting plates, with a second mounting plate slidably connected to the connecting plate.
[0006] To further explain, the second mounting base and the first mounting base have a detachable connection structure.
[0007] To further explain, rubber pads are installed on the inner side of each contact block.
[0008] To further explain, the second mounting plate has mounting holes.
[0009] To further explain, three second dampers are provided between the second mounting plate and the connecting plate, and each of the second dampers is fitted with a disc spring.
[0010] To further explain, six third dampers are provided between the second mounting plate and the first mounting plate, and each of the third dampers contains a second spring.
[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows: This invention efficiently dissipates horizontal energy and automatically resets through the synergistic action of horizontal sliding, contact blocks, a first damper, and rubber pads. By using disc springs and multiple sets of dampers in series, it achieves multi-level efficient buffering and energy dissipation in the vertical direction. The overall structure significantly improves the building's seismic isolation, wind resistance, and impact resistance, enhances stability and overturning resistance, reduces structural damage, extends the building's service life, and is easy to install and maintain.

Detailed Implementation
[0016] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.
[0017] A sliding base for a building structure, such as Figures 1-3As shown, the system includes a first mounting base 1, with second mounting bases 2 on both the left and right sides of the first mounting base 1. The second mounting bases 2 and the first mounting base 1 are connected by a detachable structure. A connecting block 4 is slidably installed inside the first mounting base 1. A first mounting plate 3 is installed on the top of the connecting block 4. A first damper 6 is installed on both the left and right sides of the first mounting base 1. A first spring 7 is installed on each of the first dampers 6. A contact block 5 is installed inside each of the first dampers 6. The contact blocks 5 can contact the connecting block 4. A rubber pad 8 is installed inside each of the contact blocks 5. A connecting plate 9 is installed on the top of the first mounting plate 3. A second mounting plate 10 is slidably connected to the connecting plate 9. The second mounting plate 10 has mounting holes. Three second dampers 11 are installed between the second mounting plate 10 and the connecting plate 9. A disc spring 12 is sleeved on each of the second dampers 11. Six third dampers 13 are installed between the second mounting plate 10 and the first mounting plate 3. A second spring 14 is installed inside each of the third dampers 13.
[0018] It should be noted that the core of the sliding base's working principle lies in the synergistic effect of a multi-level buffer structure to effectively dissipate the horizontal and vertical energy generated by external forces (such as earthquakes, wind loads, and thermal expansion and contraction) in the building, reducing structural response while maintaining connection stability. During initial installation, the second mounting base 2 is fixed to the foundation, and the first mounting base 1 is installed on it via a detachable connection structure, ensuring the overall foundation's stability. The building load is transmitted downwards through the mounting holes of the second mounting plate 10, acting on the connecting plate 9. In the vertical direction, the three second dampers 11 and their fitted disc springs 12, positioned between the second mounting plate 10 and the connecting plate 9, constitute the first barrier. The key buffer, when a vertical impact or continuous vibration is transmitted, the disc spring 12, due to its disc-shaped structure, has high load-bearing capacity and excellent elastic deformation characteristics, and quickly compresses or rebounds to absorb part of the instantaneous impact energy. At the same time, the second damper 11 generates viscous resistance, converting part of the kinetic energy absorbed by the disc spring 12 into heat energy dissipation, effectively suppressing the amplitude and transmission rate of vertical vibration. The high rigidity of the disc spring 12 also ensures the stable support of the structure under static or small-amplitude vibration, avoiding excessive sinking. More comprehensive buffering is provided by six third dampers 13 set between the second mounting plate 10 and the first mounting plate 3. The third dampers 13 and their built-in second springs 14 constitute the third... Two vertical buffer nets, evenly distributed, provide multi-point elastic support and damping energy dissipation. When the second mounting plate 10 is subjected to dynamic or static loads, the third damper 13 is compressed synchronously, and the second spring 14 inside it undergoes elastic deformation to store energy. The piston movement of the damper generates resistance, dissipating kinetic energy as heat. The coordinated work of the six third dampers 13 not only enhances the overall vertical vibration reduction effect but also balances the load distribution, improving the system's anti-overturning ability. It is particularly suitable for handling eccentric moments caused by uneven weight distribution or tilted loads in buildings. The horizontal energy dissipation mechanism is mainly integrated inside the first mounting base 1, and the connecting block 4 is slidably set in the second... Inside a mounting base 1, the first mounting plate 3 at its top is connected to the aforementioned buffer system. Under the action of lateral forces (such as seismic shear waves, wind thrust, or thermal expansion and contraction stress), the building transmits the horizontal load to the connecting block 4 through the second mounting plate 10, the connecting plate 9, and the first mounting plate 3. When the connecting block 4 slides within the first mounting base 1, it will squeeze the contact blocks 5 on the left and right sides. The rubber pad 8 installed at the front end of the contact block 5 utilizes the high coefficient of friction and viscoelastic properties of the material to dissipate part of the kinetic energy through micro-deformation and frictional heat generation, and provides an initial buffer to reduce hard impacts. Its elasticity can also assist in the reset after the force is unloaded. The contact block 5 is rigidly connected to the first damper 6.When the connecting block 4 applies pressure to the contact block 5, causing it to move backward, the damping medium (such as hydraulic oil or polymer material) in the first damper 6 generates significant viscous resistance, converting the kinetic energy transmitted from the connecting block 4 into heat energy. Simultaneously, the first spring 7 on the first damper 6 is compressed, storing elastic potential energy. When the lateral force weakens or disappears, the potential energy stored in the first spring 7 is released, pushing the contact block 5 along with the rubber pad 8 back to its original position. The rubber pad 8 on the inner side of the contact block 5 again assists in smoothly resetting to its original center position through friction with the connecting block 4, avoiding rebound oscillation caused by the rapid release of energy by the elastic element. The second mounting base 2, installed on the first mounting base 1 on the left and right sides, not only provides a fixed fulcrum, but its detachable connection structure also facilitates the installation, maintenance, or flexible configuration and replacement of the entire device under special working conditions. The horizontal buffer mechanism within the first mounting base 1 and the vertical buffer system between the mounting plates respond in concert: lateral force drives the connecting block 4 to slide, activating the horizontal energy-dissipating reset chain of the first damper 6, the first spring 7, and the rubber pad 8; vertical force is mainly absorbed and attenuated through a multi-stage energy-dissipating network composed of disc spring 12, second damper 11, third damper 13, and second spring 14. This three-dimensional buffer structure ensures that the main body of the building can achieve controllable sliding displacement under complex dynamic loads such as earthquakes, and can also efficiently dissipate energy through internal damping elements, significantly reducing the peak acceleration input to the upper structure. The combined action of disc spring 12, multiple springs, and multiple dampers endows the base with the continuous and effective vibration suppression capability and reliable structural stability required to cope with conventional wind vibration, equipment vibration, thermal stress, and long-term load changes.
[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
