Abstract
Description
Technical Field
[0001] This utility model relates to the field of friction pendulum support technology, specifically to a friction pendulum support with a tenon structure. Background Technology
[0002] Friction pendulum bearings are a common type of bearing in construction. When an earthquake occurs, relative sliding occurs between two sliding friction surfaces inside the bearing. The frictional force generated during this sliding process dissipates seismic energy. The design of friction pendulum bearings allows the structure to swing like a pendulum under seismic loads, which can significantly prolong the structure's natural period. This, in turn, reduces the impact frequency and intensity of seismic forces on the structure.
[0003] Friction pendulum supports have an upper support. Due to the thickness of the upper support, machining it is usually time-consuming, thus reducing machining efficiency. Therefore, there is an urgent need to design a friction pendulum support with a locking mechanism to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a friction pendulum support with a latch structure to address the aforementioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A friction pendulum support with a tenon structure includes an upper support plate, a lower support plate at the bottom of the upper support plate, a first connecting plate, a second connecting plate at the top of the first connecting plate, tenon grooves on the outer walls of both the first and second connecting plates, a tenon plate inside the tenon groove, a countersunk hole on one side of the outer wall of the tenon plate, a fastening bolt inside the countersunk hole, one end of the fastening bolt being threaded to the second connecting plate, and a tenon post between the first and second connecting plates.
[0007] Furthermore, the bottom outer wall of the connecting base plate 2 has a connecting hole 1, the top outer wall of the connecting base plate 1 has a connecting hole 2, the top end of the tenon post is inserted into the interior of the connecting hole 1, and the bottom end of the tenon post is inserted into the interior of the connecting hole 2.

[0009] Furthermore, a spherical crown is provided between the connecting seat plate one and the lower support plate, a cavity one is provided on the top outer wall of the lower support plate, and a cavity two is provided at the bottom of the connecting seat plate one. The bottom and top of the spherical crown are respectively adapted to the cavity one and the cavity two.
[0010] Furthermore, a limiting plate is fixed to the top outer wall of the lower support plate, and a mating opening is opened inside the limiting plate, into which the bottom of the connecting seat plate is inserted.
[0011] Furthermore, a sleeve is fixed to the bottom outer wall of the lower support plate, and an anchor rod is inserted into the inside of the sleeve.
[0012] In the above technical solution, the friction pendulum support with a tenon structure provided by this utility model has the following advantages: The upper support plate is divided into two parts, allowing for simultaneous processing of both the first and second connecting plates during the processing of the upper support plate, thus improving processing efficiency. The tenon plate fixes the first and second connecting plates, enabling them to withstand greater forces. This allows for selection of the installation method of the upper support plate according to actual construction conditions, making installation more flexible.

Detailed Implementation
[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0021] like Figure 1-4 As shown in the figure, the friction pendulum support with a tenon structure provided in this embodiment of the present invention includes an upper support plate 1, a lower support plate 3 at the bottom of the upper support plate 1, the upper support plate 1 includes a connecting plate 1 2, a connecting plate 2 4 at the top of the connecting plate 1 2, tenon grooves 18 are opened on the outer walls of both the connecting plate 1 2 and the connecting plate 2 4, a tenon plate 13 is provided inside the tenon groove 18, a countersunk hole 19 is opened on one side of the outer wall of the tenon plate 13, a fastening bolt 20 is provided inside the countersunk hole 19, one end of the fastening bolt 20 is threadedly connected to the connecting plate 2 4, and a tenon post 12 is provided between the connecting plate 1 2 and the connecting plate 2 4.
[0022] Specifically, in this embodiment, it includes an upper support plate 1, a lower support plate 3 at the bottom of the upper support plate 1, a connecting plate 2 at the top of the connecting plate 2, and a connecting plate 4 at the bottom of the connecting plate 2. Both the connecting plate 2 and the connecting plate 4 have tenon grooves 18 on their outer walls. The tenon grooves 18 are trapezoidal in shape, and a tenon plate 13 is installed inside the tenon grooves 18. A countersunk hole 19 is formed on one side of the outer wall of the tenon plate 13, and a fastening bolt 20 is installed inside the countersunk hole 19. One end of the fastening bolt 20 is screwed into the connecting plate 4. The grooved connection allows the fastening bolts 20 to fix the tenon plate 13 inside the tenon groove 18. At the same time, there are multiple tenon plates 13 between the connecting seat plate 1 2 and the connecting seat plate 2 4, making the connection between the connecting seat plate 1 2 and the connecting seat plate 2 4 more secure. Tenon posts 12 are provided between the connecting seat plate 1 2 and the connecting seat plate 2 4. There are at least two tenon posts 12. The tenon posts 12 are inserted into the connecting hole 1 10 and the connecting hole 2 11, so that the connecting seat plate 1 2 and the connecting seat plate 2 4 can withstand sufficient shear force.
[0023] This utility model provides a friction pendulum support with a tenon structure, which divides the upper support plate 1 into two parts, allowing the connecting plate 2 and the connecting plate 4 to be processed simultaneously during the processing of the upper support plate 1, thus improving processing efficiency. The connecting plate 2 and the connecting plate 4 are fixed by the tenon plate 13, enabling them to withstand greater forces. This allows for selection of the installation method of the upper support plate 1 according to the actual construction conditions. For example, when the construction is difficult, the connecting plate 2 and the connecting plate 4 can be installed one by one; when the construction is easier, the connecting plate 2 and the connecting plate 4 can be assembled together first, and then the assembled upper support plate 1 can be installed as a whole on the support, thus making the installation of the upper support plate 1 more flexible.
[0024] In another embodiment of this utility model, the bottom outer wall of the connecting base plate 2 has a connecting hole 10, and the top outer wall of the connecting base plate 2 has a connecting hole 11. The top end of the tenon post 12 is inserted into the interior of the connecting hole 10, and the bottom end of the tenon post 12 is inserted into the interior of the connecting hole 11. A central hole 16 is opened at the center of the tenon post 12, and a radial hole 17 is opened in the middle of the tenon post 12. The central hole and the radial hole 17 are connected. Through the central hole and the radial hole 17, when the tenon post 12 is inserted into the connecting hole 10 and the connecting hole 11, the air inside the connecting hole 10 and the connecting hole 11 can flow out from the central hole and the radial hole 17, preventing the air from obstructing the installation of the tenon post 12.
[0025] In another embodiment of this utility model, a spherical crown 7 is provided between the connecting seat plate 1 2 and the lower support plate 3. The top and bottom outer walls of the spherical crown 7 are both arc-shaped surfaces. A cavity 1 8 is provided on the top outer wall of the lower support plate 3, and a cavity 2 9 is provided on the bottom of the connecting seat plate 1 2. The bottom and top of the spherical crown 7 are adapted to the cavity 1 8 and cavity 2 9, respectively, so that under seismic action, the support can swing the upper part of the bridge like a pendulum, prolonging the natural vibration period of the bridge structure, thereby reducing the impact frequency and intensity of seismic forces on the structure; A limiting plate 14 is fixed to the top outer wall of the bearing plate 3. The limiting plate 14 has a mating opening 15 inside. The bottom of the connecting seat plate 2 is inserted into the mating opening 15. The limiting plate 14 limits the lower bearing plate 3. The limiting plate 14 and the lower bearing plate 3 are fixed by a shear pin. Under seismic action, the shear pin fixing the limiting plate 14 will break due to overload, thus causing the bearing to enter the seismic isolation condition. A sleeve 5 is fixed to the bottom outer wall of the lower bearing plate 3. An anchor rod 6 is inserted into the sleeve 5. The anchor rod 6 realizes the function of fixing the bearing.
[0026] Working principle: When assembling connecting plate 12 and connecting plate 24, first insert the tenon 12 into the connecting hole 21, then place connecting plate 24 on connecting plate 12, so that the top of the tenon 12 is inserted into the connecting hole 10 on the bottom outer wall of connecting plate 24; then place the tenon plate 13 into the tenon groove 18, and then insert the fastening bolt 20 into the countersunk hole 19, so that the fastening bolt 20 is threadedly connected to connecting plate 24, thereby fixing connecting plate 12 and connecting plate 24.
[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
