Description

Technical Field

[0001] This utility model relates to a seismic isolation layer structure. Background Technology

[0002] With the development of the construction industry and the continuous expansion of building scale and quantity, the need for building safety is also increasing. Furthermore, the numerous large earthquakes that have caused significant damage to buildings have brought widespread attention to the issue of seismic isolation and damping, posing a significant challenge to the construction industry's design requirements for these technologies. Therefore, construction companies need to improve and optimize building seismic isolation and damping structures, innovate application measures for seismic isolation and damping, thereby enhancing the overall performance of building seismic isolation and damping, improving buildings' ability to withstand earthquakes, and protecting people's lives and property.

[0003] Important public buildings and lifeline infrastructure such as hospitals, schools, museums, and nuclear power plants. These buildings need to be quickly restored to function after an earthquake to support rescue and reconstruction efforts. Seismic isolation technology can effectively protect the structure and internal facilities of these buildings, ensuring their safety and reliability during earthquakes.

[0004] Seismic isolation technology involves placing a seismic isolation layer between the foundation and the superstructure of a building. This layer extends the natural period of the structure, avoiding the dominant period of an earthquake, thereby reducing the transmission of seismic energy to the upper structure. The seismic isolation layer mainly consists of components such as seismic isolation bearings and dampers. Seismic isolation bearings provide flexible support, allowing the building to slide horizontally relative to the ground under seismic loads; dampers dissipate seismic energy, control the displacement of the seismic isolation layer, and prevent excessive deformation of the seismic isolation bearings.

[0005] In existing buildings, the seismic isolation layers are often constructed with seismic isolation bearings on the same horizontal plane, and adjacent seismic isolation bearings are independent and not connected to each other. This type of seismic isolation layer structure undergoes horizontal displacement after vibration and is prone to excessive horizontal deformation. It lacks integrity, which reduces the lifespan of the seismic isolation bearings and results in a long displacement recovery time, making it unable to quickly return to its initial position. When continuous vibration occurs, the seismic performance of the building decreases. Utility Model Content

[0006] This invention addresses the problem of poor integrity and earthquake resistance of existing building seismic isolation layer structures by proposing a new building seismic isolation layer structure.

[0007] The seismic isolation layer structure of this utility model consists of multiple concrete columns, a first seismic isolation bearing (1), a second seismic isolation bearing (2), a first diagonal brace (6), and a second diagonal brace (7); each concrete column consists of an upper concrete column (3), a middle concrete column (4), and a lower concrete column (5); the first seismic isolation bearing (1) is located between the upper concrete column (3) and the middle concrete column (4), and the second seismic isolation bearing (2) is located between the middle concrete column (4) and the lower concrete column (5). Between; the first seismic isolation bearings (1) in adjacent concrete columns are staggered in height, and the second seismic isolation bearings (2) in adjacent concrete columns are staggered in height; the upper part of the first seismic isolation bearing (1) in the same concrete column is connected to the lower part of the second seismic isolation bearing (2) in the adjacent concrete column by the first diagonal brace (6), and the lower part of the second seismic isolation bearing (2) in the same concrete column is connected to the upper part of the first seismic isolation bearing (1) in the adjacent concrete column by the second diagonal brace (7).

[0008] The principle and beneficial effects of this utility model are as follows:

[0009] In the seismic isolation layer structure of this utility model, each concrete column is composed of an upper concrete column (3), a middle concrete column (4), and a lower concrete column (5). Two seismic isolation supports are set in each concrete column, which improves the vertical blocking and loss of seismic energy. When continuous vibration occurs, the two seismic isolation supports share the displacement deformation and seismic energy loss, which shortens the recovery time and enables rapid recovery to the initial position, so as to continue to play a vibration isolation role in continuous vibration. At the same time, the first seismic isolation support (1) and the second seismic isolation support (2) in adjacent concrete columns are staggered in height, and the adjacent concrete columns are connected by the first diagonal tie (6) and the second diagonal tie (7), connecting the concrete columns into a whole. When vibration occurs, the synchronization of the concrete column, the first seismic isolation support (1) and the second seismic isolation support (2) is improved, avoiding damage or failure caused by excessive local load, and improving the overall safety and reliability of the building.
