Description

Technical Field

[0001] This invention relates to the field of building vibration reduction and isolation technology, specifically to a three-dimensional deformation limiting support device and its application. Background Technology

[0002] In building construction, disc spring supports, thick-layer rubber supports, or three-dimensional seismic isolation rubber supports are often installed under the building to reduce vibrations caused by subways, earthquakes, etc.

[0003] Traditional disc spring bearings and thick-layered rubber bearings are used in buildings to reduce vertical vibration or seismic forces. Increasing the thickness of the rubber layer can effectively reduce vertical vibration. To prevent horizontal overturning, guide rods need to be added in the horizontal direction to prevent horizontal deformation. Therefore, this type of bearing does not have the ability to isolate seismic forces in the horizontal plane. Ordinary laminated bearings have poor vertical elasticity and small deformation, resulting in extremely poor vertical vibration reduction. Therefore, it is difficult for a single laminated rubber bearing to exert its ability to reduce vertical vibration and dissipate horizontal energy. At present, two types of laminated rubber bearings are often used in combination, which brings problems such as complex processes and high costs. Summary of the Invention

[0004] This invention provides a three-dimensional deformation limiting support device and its application. During horizontal displacement, the retaining rings slide against each other to support the seismic isolation bearing and ensure that it does not roll or tilt. Furthermore, energy-dissipating core materials can be added inside to realize energy dissipation function, fully integrating the vertical vibration reduction and horizontal seismic isolation functions of the seismic isolation bearing into one.

[0005] The specific technical solution of this invention is as follows:

[0006] A three-dimensional deformation limiting support device includes a base plate 2, one or more retaining rings 3, an upper plate 4, and a top plate 5. The base plate 2, one or more retaining rings 3, the upper plate 4, and the top plate 5 are stacked from bottom to top. The base plate 2 has an inverted T-shaped structure. The retaining rings 3 have a groove 9 at the bottom and a boss 10 at the top. The diameter of the groove 9 is larger than the outer diameter of the boss 10. The retaining rings 3 are stacked. The vertical end of the T-shaped structure of the base plate 2 is located in the groove 9 of the first retaining ring. The boss 10 of the lower retaining ring is located in the groove 9 of the upper retaining ring. The bottom of the upper plate 4 has the same groove as the retaining rings 3. The top of the upper plate 4 has a small groove. The top plate 5 has a regular T-shaped structure. The vertical end of the regular T-shaped structure is located in the small groove.

[0007] The three-dimensional deformation limiting support device also includes three or more disc springs I6. One end of the disc spring I6 is connected to the top edge of the upper plate 4, and the other end of the disc spring I6 is connected to the corner of the T-shaped structure of the top plate 5. The three or more disc springs I6 are evenly distributed around the vertical end of the T-shaped structure.

[0008] The three-dimensional deformation limiting support device also includes three or more disc springs II7. One end of the disc spring II7 is connected to the bottom of the vertical end of the T-shaped structure of the top plate 5, and the other end is connected to the bottom edge of the small groove of the upper plate 4. The three or more disc springs I6 are evenly distributed in the small groove.

[0009] The three-dimensional deformation limiting support device also includes a lead core 8, which vertically passes through the center of the retaining ring 3, with its bottom entering the interior of the base plate 2 and its top entering the interior of the upper plate 4. When the device slides horizontally, it can cause the internal energy-consuming core material lead core to deform and generate energy consumption. The lead core 8 can also be wrapped with a flexible sealing sleeve, which is made of rubber or other materials. The flexible sealing sleeve deforms together with the lead core 8, and the rubber flexible sealing sleeve can, to a certain extent, reset the lead core.

[0010] The retaining ring 3 is made of a non-flexible material, such as stainless steel plate or hard plastic.

[0011] The present invention also provides the application of the three-dimensional deformation limiting support device, which is installed inside or outside the support body 1. When installed outside, it is evenly distributed around the support body 1. During installation, the lower plane of the bottom plate 2 is on the same plane as the lower plane of the support body 1, and the upper plane of the top plate 5 is on the same plane as the upper plane of the support body 1.

[0012] The bearing body 1 includes, but is not limited to, ordinary rubber bearings, high-damping rubber bearings, sliding bearings, etc., including, but not limited to, thick-layered bearings of these bearings.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) In the three-dimensional deformation limiting support device of the present invention, one or more clasps form a clasp energy dissipation group. When applied to a rubber support, the height of the clasp energy dissipation group is lower than the height of the support. It can move horizontally together with the rubber support and generate energy dissipation. At the same time, the clasp group supports the rubber support to ensure that the support does not tilt or flip horizontally due to pressure eccentricity when the rubber layer is too thick during horizontal deformation. Furthermore, the clasp group can also be set to allow the horizontal displacement of the support as needed.

[0015] (2) The disc spring at the end of the energy dissipation group of the three-dimensional deformation limiting support device of the present invention, in conjunction with the T-shaped top plate, can adjust the vertical elasticity and displacement of the rubber support to achieve different vertical vibration reduction requirements. Furthermore, by adjusting the number and combination of disc springs, different elastic stiffness and displacement can be achieved, thus broadening the vertical vibration reduction frequency range of the rubber support.

The retaining rings 3 have grooves 9 at their bottom and protrusions 10 at their top. The diameter of the grooves 9 is larger than the outer diameter of the protrusions 10. The three retaining rings 3 are stacked from bottom to top. The vertical end of the T-shaped structure of the base plate 2 is located in the groove 9 of the first retaining ring. The protrusion 10 of the first retaining ring is located in the groove 9 of the second retaining ring, and the protrusion 10 of the second retaining ring is located in the groove 9 of the third retaining ring. The upper plate... The bottom of plate 4 has the same groove as the retaining ring 3. The protrusion 10 of the third retaining ring is set in the lower groove of the upper plate 4. The top of the upper plate 4 has a small groove. The top plate 5 has a T-shaped structure, and the vertical end of the T-shaped structure is located in the small groove. One end of the disc spring I6 is connected to the top edge of the upper plate 4, and the other end of the disc spring I6 is connected to the corner of the T-shaped structure of the top plate 5. The four disc springs I6 are evenly distributed around the vertical end of the T-shaped structure, which stabilizes the top plate 5 to a certain extent. The retaining ring 3 is made of a non-flexible material, such as stainless steel. When viewed from above, the outer edges of the bottom plate 2, the three retaining rings 3, the upper plate 4, and the top plate 5 are all circular.

[0029] like Figure 4 The diagram shows the structure of the three-dimensional deformation limiting support device applied inside the rubber bearing body in this embodiment. The device of this embodiment is installed inside the rubber bearing body. The bearing body 1 is an ordinary rubber bearing. In this embodiment, the ordinary thick-layered rubber bearing body is first produced according to conventional methods. Then, according to the size of the central hole, the base plate 2, three retaining rings 3, upper plate 4, and top plate 5 are produced. The two ends of the disc spring I6 are welded to the top edge of the upper plate 4 and the corner of the T-shaped structure of the top plate 5. They are placed into the central hole in sequence. The outer edges of the base plate 2, three retaining rings 3, upper plate 4, and top plate 5 are equal to the central hole. During installation, the lower plane of the base plate 2 is on the same plane as the lower plane of the bearing body 1, and the upper plane of the top plate 5 is on the same plane as the upper plane of the bearing body 1. Then, flange plates are installed on the upper and lower surfaces of the bearing body 1. Finally, the whole assembly is installed in the required location.

[0030] Example 2

[0031] A three-dimensional deformation limiting support device, such as Figure 5 As shown, based on Embodiment 1, it also includes four disc springs II7. One end of disc spring II7 is connected to the bottom of the vertical end of the T-shaped structure of the top plate 5, and the other end is connected to the bottom edge of the small groove at the top of the upper plate 4.

[0032] Example 3

The lead core 8 vertically passes through the center of the retaining ring 3, with its bottom entering the interior of the base plate 2 and its top entering the interior of the upper plate 4. In application, when the support body 1 slides horizontally, it can cause the internal energy-dissipating core material to deform and generate energy dissipation. To increase the diversity of energy dissipation in the horizontal direction of the support, the type of energy-dissipating core material can be changed to give the support horizontal plane different damping and shock absorption effects. A flexible sealing sleeve can also be wrapped around the lead core 8. The flexible sealing sleeve is made of rubber or similar materials. The flexible sealing sleeve deforms together with the lead core 8. The rubber flexible sealing sleeve can, to a certain extent, reset the lead core. The support body 1 is a thick-layered rubber support prepared with a sliding support formula. Other components and the structural relationships between components are the same as in Example 2.

It adds a central lead core and a flexible sealing sleeve. Its overall preparation and usage methods are the same as in Embodiment 2.
