Description

Technical Field

[0001] The invention relates to the technical field of building friction pendulums, and in particular to a building friction pendulum. Background Art

[0002] The building friction pendulum (FPS) is a connection device installed between the bases of buildings. When an earthquake occurs, the upper and lower parts of the building friction pendulum (FPS) will slide relative to each other at a certain period, and friction will be generated on the sliding interface. This friction resists the sliding of the building, reducing the relative displacement of the building in the earthquake wave, thereby reducing the impact of the earthquake force on the building and consuming a large amount of earthquake energy, achieving the effect of buffering energy consumption between the bases of the buildings, so that the buildings above the base are not easily destroyed by the earthquake.

[0003] For example, China's authorization publication number is CN 221073035 U, which discloses an anti-detachment building friction pendulum seismic isolation bearing, which discloses a building friction pendulum that remains in a compressed state when under tension, so that the seismic isolation function can be performed normally, thereby ensuring that the building seismic isolation measures can effectively function.

[0004] At present, the architectural friction pendulum mainly includes two parts, an upper spherical crown lining and a lower spherical crown lining are arranged near the upper and lower parts, and a sliding part is arranged between the upper spherical crown lining and the lower spherical crown lining. However, the upper spherical crown lining and the lower spherical crown lining are affected by the material, so that the surface roughness is not uniform, and the overall friction coefficient is different. The friction coefficient is a key parameter for controlling the damping size. The different friction coefficients lead to poor overall energy consumption effect, thereby reducing the overall buffering energy consumption effect. Summary of the invention

[0005] To this end, the present invention provides a building friction pendulum to solve the problem in the prior art that the surface roughness is not uniform and the friction coefficient is different, resulting in poor overall energy dissipation effect, thereby reducing the overall buffering energy dissipation effect.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] The architectural friction pendulum comprises a first reinforcing sleeve, a first spherical cap and a positioning column.

[0008] A carbon steel plate is installed at the outer end of the first reinforcing sleeve, and a positioning ring is provided at the outer edge of the carbon steel plate, and a stainless steel plate is provided in contact with the outer surface of the carbon steel plate;

[0010] The positioning column is fixedly installed at the outer edge of the carbon steel plate.

[0011] Furthermore, a first reinforcing plate is integrally fixedly installed on the outer side of the lower end of the first reinforcing sleeve, and a second reinforcing sleeve is correspondingly arranged above the first reinforcing sleeve, and a second reinforcing plate is integrally fixedly installed on the outer side of the upper end of the second reinforcing sleeve.

[0012] Furthermore, the outer edge of the stainless steel plate is located in the gap between the carbon steel plate and the positioning ring, and hexagonal cylindrical head screws are uniformly arranged through the interior of the carbon steel plate and the positioning ring.

[0013] Furthermore, the positioning block is inserted into the interior of the carbon steel plate, and prefabricated through holes for installing welding nails are provided inside the positioning block and the carbon steel plate.

[0014] Furthermore, the threaded steel bar is arranged to penetrate the interior of the positioning column.

[0015] Furthermore, one end of the positioning column away from the carbon steel plate is respectively penetrated into the interior of the first reinforcement sleeve and the second reinforcement sleeve.

[0016] Furthermore, the middle portion of the stainless steel plate is concavely arranged, and the curvatures of the upper and lower sides of the first spherical crown are adapted to the curvature of the stainless steel plate.

[0017] Furthermore, a second spherical crown is provided in the middle of the upper end of the stainless steel plate, and an upper spherical crown body is connected to the outer side of the upper end of the second spherical crown.

[0018] Furthermore, the upper and lower ends of the second spherical crown are both arc-shaped, and are respectively adapted to be connected to the upper spherical crown body and the stainless steel plate, and an upper mounting plate located above the stainless steel plate is fixedly installed on the outer side of the upper end of the upper spherical crown body.

[0019] Compared with the prior art, this application has at least the following beneficial effects:

[0020] 1. Through the stainless steel plate, the middle part of the stainless steel plate is concave, and the surface roughness of the stainless steel plate is uniform, so that the overall friction coefficient is consistent, which is convenient for improving the overall energy consumption effect and better achieving the effect of buffering energy consumption between the building and the building base;

[0022] 3. Through the first spherical crown and the second spherical crown, the first spherical crown and the second spherical crown can slide relative to the stainless steel plate and generate friction, thereby achieving the effect of buffering energy consumption between the bases of the buildings. Before installation, the first reinforcing sleeve and the second reinforcing sleeve as well as the first reinforcing sleeve and the upper spherical crown can be selected according to actual conditions, which saves costs and is convenient to use.

[0035] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] like Figures 1 to 4 As shown, the building friction pendulum in the embodiment of the first aspect of the present invention comprises: a first reinforcing plate 9 is integrally fixedly installed on the outer side of the lower end of the first reinforcing sleeve 1, and the first reinforcing sleeve 1 plays a good supporting and installing role for the first reinforcing plate 9; a second reinforcing sleeve 10 is correspondingly arranged above the first reinforcing sleeve 1, and a second reinforcing plate 11 is integrally fixedly installed on the outer side of the upper end of the second reinforcing sleeve 10, and the second reinforcing sleeve 10 and the second reinforcing plate 11 play a good supporting and installing role. In the manufacturing process, a building friction pendulum comprising the first reinforcing sleeve 1, the first reinforcing plate 9, the second reinforcing sleeve 10 and the second reinforcing plate 11 is manufactured through a production line, and then concrete is poured between the first reinforcing sleeve 1 and the second reinforcing sleeve 10 through the hole-like structures pendulumed through the middle of the first reinforcing plate 9 and the second reinforcing plate 11 to obtain the first building friction pendulum. The finished friction pendulum is constructed, and concrete can significantly improve its overall rigidity and stability, preventing it from being deformed or damaged when subjected to external force or vibration. Then, the first finished friction pendulum is brought to the site for installation, so that the whole is installed between the bases of the buildings. The second reinforcing plate 11 and the first reinforcing plate 9 are respectively connected to the outer surfaces of the bases of the buildings and the buildings. The carbon steel plate 2 is installed on the outer end of the first reinforcing sleeve 1. A positioning ring 4 is provided at the outer edge of the carbon steel plate 2. A stainless steel plate 3 is provided on the outer surface of the carbon steel plate 2. The diameter of the carbon steel plate 2 is respectively the same as the diameter of the first reinforcing sleeve 1 and the second reinforcing sleeve 10. During installation, the carbon steel plate 2 can be placed on the outer side of the upper end of the first reinforcing sleeve 1, and the stainless steel plate 3 can be installed on the outer side of the upper end of the carbon steel plate 2, so that the carbon steel plate 2 can play a better supporting role on the stainless steel plate 3.

[0038] The outer surface of the stainless steel plate 3 is integrally fixedly installed with a positioning block 14, which is inserted and arranged inside the carbon steel plate 2. The inside of the carbon steel plate 2 is evenly installed with welding nails 8 located in the first reinforcing sleeve 1 at equal angles, and the positioning block 14 and the carbon steel plate 2 are both provided with prefabricated through holes 12 for installing the welding nails 8. When the stainless steel plate 3 is installed, the positioning block 14 can be inserted into the hole-shaped structure adapted to it opened inside the carbon steel plate 2 one by one. At this time, the positioning block 14 plays a good positioning role for the stainless steel plate 3, which is convenient for improving the connection effect between the stainless steel plate 3 and the carbon steel plate 2, and then the welding nails 8 are inserted into the prefabricated through holes 12 opened inside the carbon steel plate 2 and the positioning block 14 and welded, so as to facilitate the fixing of the stainless steel plate 3 and improve the firmness of the stainless steel plate 3 installed on the outside of the carbon steel plate 2;

[0039] Threaded steel bars 7 are arranged at equal angles at the outer edge of the carbon steel plate 2, and the positioning column 13 is fixedly installed at the outer edge of the carbon steel plate 2. The threaded steel bars 7 are penetrated inside the positioning column 13, and the ends of the positioning column 13 away from the carbon steel plate 2 are respectively penetrated inside the first reinforcing sleeve 1 and the second reinforcing sleeve 10. The positioning column 13 and the threaded steel bars 7 are arranged in a one-to-one correspondence. After the stainless steel plate 3 and the carbon steel plate 2 are fixedly installed, the positioning column 13 can be inserted into the through hole structure opened inside the upper end of the first reinforcing sleeve 1. At this time, the positioning column 13 has a good positioning effect on the carbon steel plate 2, which is convenient for accurately installing the carbon steel plate 2 on the outer side of the upper end of the first reinforcing sleeve 1, so that the threaded holes opened in the carbon steel plate 2 and the first reinforcing sleeve 1 are aligned with each other;

[0040] The outer edge of the stainless steel plate 3 is located in the gap at the connection between the carbon steel plate 2 and the positioning ring 4, and the carbon steel plate 2 and the positioning ring 4 are penetrated by hexagonal cylindrical head screws 6 at equal angles. The middle part of the stainless steel plate 3 is concave, and the upper and lower curvatures of the first spherical crown 5 are compatible with the curvature of the stainless steel plate 3. The positioning ring 4 is placed on the outer side of the upper end of the carbon steel plate 2. At this time, the positioning ring 4 is located on the outer side of the edge of the stainless steel plate 3, which can effectively prevent the stainless steel plate 3 from warping. The hexagonal cylindrical head screw 6 is then inserted into the positioning ring 4, the carbon steel plate 2 and the first reinforcing sleeve 1 to facilitate fixing the positioning ring 4. Similarly, the above steps are installed to install the above parts in the second reinforcing sleeve 10 in sequence. During installation The first spherical crown 5 can be placed in the middle of the upper end of the stainless steel plate 3 in the first reinforcing sleeve 1, and then the second reinforcing sleeve 10 can be placed and installed on the outer side of the upper end of the first reinforcing sleeve 1, so that the stainless steel plate 3 in the second reinforcing sleeve 10 is in contact with the outer side of the upper end of the first spherical crown 5. The surface roughness of the stainless steel plate 3 is uniform, so that the overall friction coefficient is consistent, which is convenient for improving the overall energy consumption effect. When an earthquake occurs, the two groups of stainless steel plates 3 can slide relative to the first spherical crown 5 and generate friction, so that the friction resists the sliding of the building, reduces the relative displacement of the building in the seismic wave, reduces the impact of the seismic force on the building, and consumes a large amount of seismic energy, thereby achieving the effect of buffering energy consumption between the building and the base of the building.

[0041] Example 2

[0042] like Figures 5 to 7As shown, a second spherical crown 17 is also provided in the middle of the upper end of the stainless steel plate 3. According to the above steps, the carbon steel plate 2, the stainless steel plate 3, the positioning ring 4, the first spherical crown 5, the hexagonal cylindrical head screw 6, the threaded steel 7, the welding nail 8, the first reinforcing plate 9 and the first reinforcing sleeve 1 are assembled and installed, and then the second spherical crown 17 is placed in the middle of the upper end of the stainless steel plate 3. The upper outer side of the upper end of the second spherical crown 17 is connected with an upper spherical crown body 16. The upper and lower ends of the second spherical crown 17 are both arranged in an arc shape, and the upper and lower ends of the second spherical crown 17 are respectively adapted to be connected with the upper spherical crown body 16 and the stainless steel plate 3, and the upper outer side of the upper end of the upper spherical crown body 16 is fixedly installed with an upper mounting plate 15 located above the stainless steel plate 3, and then the upper mounting plate 15 is installed on the outer side of the lower end of the building, so that the upper spherical crown body 16 is connected to the second spherical crown 17. The diameter size is smaller than the diameter size of the second spherical crown 17. At this time, the upper spherical crown body 16 and the second spherical crown 17 can be tightly connected and effectively prevented from detaching. When an earthquake occurs, the second spherical crown 17 can slide relative to the stainless steel plate 3 and generate friction, so that the friction resists the sliding of the building, reduces the relative displacement of the building in the seismic wave, reduces the impact of the seismic force on the building, and consumes a large amount of seismic energy, thereby achieving the effect of buffering energy consumption between the bases of the buildings. During the manufacturing process, the first reinforcement sleeve 1 and the second reinforcement sleeve 10 and the first reinforcement sleeve 1 and the upper spherical crown body 16 are selected according to actual conditions, and concrete is poured into the first reinforcement sleeve 1 through the hole structure opened in the middle of the first reinforcement plate 9, so as to better meet the diverse needs of the on-site conditions.

[0043] Example 3

[0044] like Figures 8 to 9 As shown;

[0045] A first reinforcing plate 9 is integrally fixedly installed on the outer side of the lower end of the first reinforcing sleeve 1, a second reinforcing sleeve 10 is correspondingly arranged above the first reinforcing sleeve 1, and a second reinforcing plate 11 is integrally fixedly installed on the outer side of the upper end of the second reinforcing sleeve 10, threaded steel bars 7 are arranged at equal angles at the outer edge of the carbon steel plate 2, and a positioning column 13 is fixedly installed at the outer edge of the carbon steel plate 2, and the threaded steel bars 7 are penetrated and arranged inside the positioning column 13. During the manufacturing process, we can flexibly adjust the production line according to the specific conditions on site to produce a building friction pendulum that does not include the first reinforcing sleeve 1, the first reinforcing plate 9, the second reinforcing sleeve 10 and the second reinforcing plate 11, so that the threaded steel bars 7 are exposed to the outside and a second building friction pendulum product is obtained. During the on-site installation process, the threaded steel bars 7 and the welding nails 8 are first fixedly installed as a whole with the on-site building and the base structure. After the installation is completed, the threaded steel bars 7 and the on-site building and the base structure are uniformly cast by the concrete pouring method to ensure that the finished building friction pendulum is firmly installed between the building and the base structure, so that the threaded steel bars 7 play a major fixing role, thereby facilitating the installation of the whole and expanding the scope of use.
