Description

Technical Field

[0001] The utility model relates to the technical field of seismic isolation devices, and particularly relates to a seismic isolation device for the foundation construction of hospital buildings. Background Art

[0002] The foundation refers to the soil or rock mass that supports the foundation under a building, which can be natural or artificially treated. The main function of the foundation is to bear all the loads transmitted from the foundation and transfer these loads together with its own weight to the underlying soil layer. The classification of the foundation includes natural foundation and artificial foundation. During the construction of existing foundations, seismic isolation devices are usually installed inside the foundation to reduce the vibration caused by earthquakes and enhance the seismic resistance of buildings. Due to the special functions of hospital buildings, they have extremely high requirements for the safety, stability and seismic performance of the buildings. Traditional foundation construction methods are difficult to meet the requirements of modern hospital buildings for seismic resistance and shock absorption. In natural disasters such as earthquakes, as an important place for emergency rescue, the safety and stability of the building structure of the hospital are directly related to the safety of people's lives and property.

[0003] The shock absorption structure of the existing seismic isolation device for the foundation construction of hospital buildings is relatively single, and the shock isolation effect is poor, resulting in poor stability of hospital buildings, thus shortening the service life of the foundation. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a seismic isolation device for the foundation construction of hospital buildings.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A seismic isolation device for the foundation construction of hospital buildings includes a ground layer. A foundation groove is opened on the upper surface of the ground layer. A plurality of installation grooves are opened on the inner wall of the foundation groove. A seismic isolation plate is arranged in the foundation groove. A plurality of sliding grooves are opened on the side wall of the seismic isolation plate;

[0007] A plurality of groups of horizontal seismic isolation components for horizontally damping the seismic isolation plate are installed in the ground layer. Each group of horizontal seismic isolation components includes a first sleeve arranged in the installation groove, a cross bar slidably connected to the inner wall of the first sleeve, a slider fixed to the end of the cross bar and slidably connected to the sliding groove, and a first spring arranged in the first sleeve. One end of the first spring is fixed to the inner wall of the sleeve, and the other end of the first spring is fixed to the end of the cross bar;

[0008] A plurality of longitudinal seismic isolation components for longitudinally damping the seismic isolation plate are installed in the foundation trench. Each longitudinal seismic isolation component includes a second sleeve fixed to the inner bottom wall of the foundation trench, a vertical rod slidably connected to the inner wall of the second sleeve, a ball embedded in the upper end of the vertical rod and rollingly connected to the bottom of the seismic isolation plate, and a second spring disposed in the second sleeve. The upper end of the second spring is fixed to the lower end of the vertical rod, and the lower end of the second spring is fixed to the inner bottom wall of the second sleeve.

[0009] By adopting the above technical solution, through the arrangement of the horizontal seismic isolation components and the longitudinal seismic isolation components, an excellent seismic isolation effect is achieved on the seismic isolation plate. When an earthquake occurs, the impact force in the horizontal direction causes the seismic isolation plate to squeeze against the horizontal seismic isolation components on one side, so that the first spring buffers the impact force in the horizontal direction. The impact force in the vertical direction causes the seismic isolation plate to drive the vertical rod to squeeze downward, and the downward pulling force generated by the second spring cancels it out, improving the stability of the hospital building and extending the service life of the foundation.

[0010] Further, the first sleeve is slidably connected to the inner wall of the installation groove. A third spring is provided in each installation groove. The upper end of each third spring is fixed to the lower surface of the first sleeve, and the lower end of each third spring is fixed to the inner bottom wall of the installation groove.

[0011] By adopting the above technical solution, when the impact force of the vertical vibration causes the seismic isolation plate to act downward, the first sleeve moves downward with the seismic isolation plate and applies a force to the third spring. The third spring buffers the downward force on the first sleeve, enhancing the protection effect on the horizontal seismic isolation components and further improving the seismic isolation effect on the seismic isolation plate.

[0012] Further, a limiting groove is provided on the inner wall of each second sleeve, and a limiting block slidably connected to the limiting groove is fixed to the side wall of each vertical rod.

[0013] By adopting the above technical solution, the limiting block is slidably connected to the limiting groove, which restricts the displacement position of the vertical rod and prevents the vertical rod from disengaging from the second sleeve upward, facilitating the normal use of the longitudinal seismic isolation components.

[0014] Further, a plurality of shock-absorbing rubbers are fixed to the inner bottom wall of the foundation trench, and the upper surface of each shock-absorbing rubber abuts against the bottom of the seismic isolation plate.

[0015] By adopting the above technical solution, the shock-absorbing rubbers play a role in supporting and strengthening the seismic isolation plate, improving the stability of the seismic isolation plate. Moreover, the shock-absorbing rubbers are made of rubber materials, and their materials are elastic. When subjected to a downward force, they will deform, thereby improving the seismic isolation effect on the seismic isolation plate.

[0016] Further, the cross-section of the shock-absorbing rubber is in an X shape.

[0017] By adopting the above technical solution, the X-shaped shock-absorbing rubber is more stable, improving the stability of the support of the shock-absorbing rubber.

[0018] Furthermore, a plurality of anti-collision pads are fixed on the side wall of the seismic isolation plate.

[0019] By adopting the above technical solution, the anti-collision pads are made of rubber material, which is elastic and plays a buffering role for the seismic isolation plate, reducing the impact force caused by the seismic isolation plate colliding with the inner wall of the foundation trench under extreme vibration.

[0020] Furthermore, a fixing groove is formed on the upper surface of the seismic isolation plate, and a plurality of seismic isolation dampers are arranged in the fixing groove, and a top plate is fixedly connected to the upper ends of the plurality of seismic isolation dampers together.

[0021] By adopting the above technical solution, the seismic isolation dampers play a buffering and shock-absorbing role for the hospital building, further enhancing the seismic isolation effect on the hospital building.

[0022] In summary, the utility model has the following beneficial effects:

[0023] 1. In this application, through the arrangement of the horizontal seismic isolation component and the vertical seismic isolation component, an excellent seismic isolation effect is achieved on the seismic isolation plate. When an earthquake occurs, the impact force in the horizontal direction causes the seismic isolation plate to squeeze against the horizontal seismic isolation component on one side, so that the first spring buffers the impact force in the horizontal direction. The impact force in the vertical direction causes the seismic isolation plate to drive the vertical rod to squeeze downward, and the downward pulling force generated by the second spring offsets it, improving the stability of the hospital building and extending the service life of the foundation.

[0024] 2. In this application, when the impact force of the vertical vibration causes the seismic isolation plate to act downward, the first sleeve acts downward on the third spring along with the seismic isolation plate, and the third spring buffers the downward force of the first sleeve, enhancing the protection effect on the horizontal seismic isolation component and further improving the seismic isolation effect on the seismic isolation plate.

[0025] 3. In this application, the shock-absorbing rubber plays a role in supporting and strengthening the seismic isolation plate, improving the stability of the seismic isolation plate. Moreover, the shock-absorbing rubber is made of rubber material, which is elastic and will deform when subjected to a downward force, thereby improving the seismic isolation effect on the seismic isolation plate.

Detailed implementation manners

[0030] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0031] As Figures 1-3 shown, the embodiment of the present application discloses a seismic isolation device for hospital building foundation construction, including a ground base layer 1, a seismic isolation plate 2, a horizontal seismic isolation component 3, and a longitudinal seismic isolation component 4.

[0032] An installation groove 111 is formed on the inner wall of the foundation groove 11 on the upper surface of the ground base layer 1. The seismic isolation plate 2 is arranged in the foundation groove 11, and a plurality of chutes 21 are formed on the side wall of the seismic isolation plate 2.

[0033] The horizontal seismic isolation component 3 is installed in the ground base layer 1 and is used for horizontally damping the seismic isolation plate 2. There are multiple groups of horizontal damping components. Each group of horizontal seismic isolation components 3 includes a first sleeve 31, a cross bar 32, a slider 33, and a first spring 34. The first sleeve 31 is a rectangular tube-shaped structure, and one side of the first sleeve 31 close to the seismic isolation plate 2 is open. The first sleeve 31 is arranged in the installation groove 111. The cross bar 32 is a horizontally arranged rectangular rod-shaped structure, and the cross bar 32 is slidably connected to the inner wall of the first sleeve 31. The slider 33 is a rectangular parallelepiped structure, and the slider 33 is fixed to the end of the cross bar 32, and the slider 33 is slidably connected to the inner wall of the chute 21. The first spring 34 is arranged in the first sleeve 31, one end of the first spring 34 is fixed to the inner wall of the sleeve, and the other end of the first spring 34 is fixed to the end of the cross bar 32.

[0034] The longitudinal seismic isolation component 4 is installed in the foundation trench 11 and is used for longitudinally damping the seismic isolation plate 2. There are multiple groups of longitudinal seismic isolation components. Each group of longitudinal seismic isolation components 4 includes a second sleeve 41, a vertical rod 42, a ball 43, and a second spring 44. The second sleeve 41 is a cuboid tubular structure with an open upper end, and the second sleeve 41 is fixed on the inner bottom wall of the foundation trench 11. The vertical rod 42 is a vertically arranged rectangular rod-shaped structure, and the vertical rod 42 is slidably connected to the inner wall of the second sleeve 41. The ball 43 is a spherical structure, and the ball 43 is embedded at the upper end of the vertical rod 42 and is in rolling connection with the bottom of the seismic isolation plate 2. The second spring 44 is arranged in the second sleeve 41. The upper end of the second spring 44 is fixed to the lower end of the vertical rod 42, and the lower end of the second spring 44 is fixed to the inner bottom wall of the second sleeve 41.

[0035] Through the arrangement of the horizontal seismic isolation component 3 and the longitudinal seismic isolation component 4, an excellent seismic isolation effect is achieved on the seismic isolation plate 2. When vibration occurs, the impact force in the horizontal direction causes the seismic isolation plate 2 to squeeze against the horizontal seismic isolation component 3 on one side, so that the first spring 34 buffers the impact force in the horizontal direction. The impact force in the vertical direction causes the seismic isolation plate 2 to drive the vertical rod 42 to squeeze downward, and the downward pulling force generated by the second spring 44 cancels it out, improving the stability of the hospital building and extending the service life of the foundation.

[0036] In order to further improve the seismic isolation effect on the seismic isolation plate 2, the first sleeve 31 is slidably connected to the inner wall of the installation groove 111. A third spring 5 is arranged in each installation groove 111. The upper end of each third spring 5 is fixed to the lower surface of the first sleeve 31, and the lower end of each third spring 5 is fixed to the inner bottom wall of the installation groove 111. During the process that the impact force of the vertical vibration causes the seismic isolation plate 2 to act downward, the first sleeve 31 moves downward with the seismic isolation plate 2 and applies a force to the third spring 5. The third spring 5 buffers the downward force on the first sleeve 31, enhancing the protection effect on the horizontal seismic isolation component 3, and thus further improving the seismic isolation effect on the seismic isolation plate 2.

[0037] In order to prevent the vertical rod 42 from disengaging from the second sleeve 41 upward, a limiting groove 411 is provided on the inner wall of each second sleeve 41, and a limiting block 6 slidably connected to the limiting groove 411 is fixed on the side wall of each vertical rod 42. The limiting block 6 is slidably connected to the limiting groove 411, which plays a role in restricting the displacement position of the vertical rod 42, thus avoiding the situation that the vertical rod 42 disengages from the second sleeve 41 upward and being beneficial to the normal use of the longitudinal seismic isolation component 4.

[0038] To improve the stability of the seismic isolation plate 2, a plurality of shock-absorbing rubbers 7 are fixed to the inner bottom wall of the foundation trench 11. The upper surface of each shock-absorbing rubber 7 abuts against the bottom of the seismic isolation plate 2. The shock-absorbing rubbers 7 play a role in supporting and strengthening the seismic isolation plate 2, thereby improving the stability of the seismic isolation plate 2. Moreover, the shock-absorbing rubbers 7 are made of rubber materials, and their materials are elastic. When subjected to a downward force, they will deform, thereby improving the seismic isolation effect on the seismic isolation plate 2.

[0039] To improve the stability of the support of the shock-absorbing rubber 7, the cross-section of the shock-absorbing rubber 7 is X-shaped. The X-shaped shock-absorbing rubber 7 is more stable, thereby improving the stability of the support of the shock-absorbing rubber 7.

[0040] To reduce the impact force caused by the seismic isolation plate 2 colliding with the inner wall of the foundation trench 11 under extreme vibrations, a plurality of anti-collision pads 8 are fixed to the side wall of the seismic isolation plate 2. The anti-collision pads 8 are made of rubber materials, and their materials are elastic, playing a buffering role for the seismic isolation plate 2, thereby reducing the impact force caused by the seismic isolation plate 2 colliding with the inner wall of the foundation trench 11 under extreme vibrations.

[0041] To further enhance the seismic isolation effect on the hospital building, fixing grooves 22 are formed on the upper surface of the seismic isolation plate 2. A plurality of seismic isolation dampers 9 are arranged in the fixing grooves 22. The upper ends of the plurality of seismic isolation dampers 9 are jointly fixed with a top plate 10. The seismic isolation dampers 9 play a role in buffering and damping for the hospital building, thereby further enhancing the seismic isolation effect on the hospital building.

[0042] The working principle of a seismic isolation device for hospital building foundation construction in this embodiment is as follows:

[0043] Through the settings of the horizontal seismic isolation assembly 3 and the vertical seismic isolation assembly 4, an excellent seismic isolation effect is achieved on the seismic isolation plate 2. When vibrations occur, the impact force in the horizontal direction causes the seismic isolation plate 2 to squeeze against the horizontal seismic isolation assembly 3 on one side, so that the first spring 34 buffers the impact force in the horizontal direction. The impact force in the vertical direction causes the seismic isolation plate 2 to drive the vertical rod 42 to squeeze downward, and the downward pulling force generated by the second spring 44 cancels it out, improving the stability of the hospital building and extending the service life of the foundation.

[0044] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
