Description

Technical Field

[0001] This invention relates to a building vibration isolation technology, and more particularly to an enhanced vibration isolation component with a steel-wood hybrid structure. Background Technology

[0002] Vibration isolation components are structural members used to reduce or control structural vibrations. They are widely used in buildings, bridges, and machinery. These components are typically made of metal, rubber, or other synthetic materials to absorb and disperse vibration energy, thereby reducing the impact of vibrations on the structure. In certain special applications, such as earthquake-sensitive areas or areas affected by external factors like wind and traffic, buildings may be affected by vibrations. The design and use of vibration isolation components are particularly important in these situations. Vibration isolation technology plays a crucial role in the construction and engineering fields.

[0003] Although existing vibration isolation technologies have achieved certain results in many applications, their performance in all-angle vibration isolation is generally limited. This means that when vibrations act on a building from different directions and angles, these vibration isolation components may not be able to effectively disperse and control the vibrations, thereby threatening the structural stability and safety of the building. In addition, due to the limitations in the design and material selection of these vibration isolation components, they may not be able to adapt to different vibration modes and frequencies, which further limits their application scope and effectiveness. Therefore, it is necessary to develop a new type of vibration isolation component to ensure the structural stability and safety of buildings. Summary of the Invention

[0004] To address the problems in the background art, this invention proposes an enhanced vibration isolation component with a steel-wood hybrid structure. Specifically, the enhanced vibration isolation component includes a foundation, a vibration isolation structure, a connecting structure, and an external casting structure.

[0005] The seismic isolation structure consists of a bottom connector, multiple wooden partitions, a steel sleeve, and a top metal plate. The lower end of the bottom connector is fixedly connected to the upper surface of the foundation. The wooden partitions are U-shaped, with multiple wooden partitions stacked on the upper surface of the bottom connector, leaving gaps between adjacent partitions to form a seismic isolation body. The steel sleeve is fitted over the seismic isolation body, and multiple limiting protrusions are provided on the inner wall of the steel sleeve, distributed along the axial direction of the steel sleeve. A wooden partition is placed between two adjacent limiting protrusions. The top metal plate is U-shaped. On the uppermost surface of the wooden partition, a plurality of first connecting holes are provided on the top metal plate, which are distributed circumferentially along the top metal plate. A plurality of second connecting holes are provided on the wooden partition, with each second connecting hole corresponding to one of the first connecting holes. Connecting posts are installed within the corresponding first and second connecting holes. The lower end of each connecting post is fixedly connected to the bottom connecting body, and a nut is installed at the upper end of the connecting post, located on the upper side of the top metal plate. The nut locks the top metal plate and the connecting post together. The circumferential profile of the vibration isolation structure is smaller than that of the foundation, and the vibration isolation structure is located in the middle of the foundation.

[0006] The connecting structure consists of a connecting platform and a supporting column. The connecting platform is a truncated pyramid structure, smaller at the top and larger at the bottom. The lower end of the supporting column is fixedly connected to the upper end of the connecting platform. The space enclosed by the inner holes of the top metal plate and the wooden partition forms an installation cavity. The outline of the installation cavity matches the shape of the connecting platform. The connecting platform is placed in the installation cavity, and its lower end face contacts the bottom connector. The inner wall of the wooden partition is an inclined surface that matches the outer wall of the connecting platform, and the inner wall of the wooden partition contacts the outer wall of the connecting platform. The upper end of the connecting platform is higher than the top metal plate. A step is provided on the outer wall of the connecting platform, and the position of the step matches the top metal plate. A steel frame is snapped onto the outer wall of the connecting platform at the step. The gap between the steel frame and the top metal plate is filled with sealant.

[0007] The externally cast structure is a concrete structure cast outside the seismic isolation structure. The height of the externally cast structure matches the height of the steel sleeve. Multiple first reinforcing bars and multiple second reinforcing bars are installed inside the externally cast structure. The axial direction of the first reinforcing bars is parallel to the upper end face of the foundation base. The multiple first reinforcing bars are arranged parallel to each other along the horizontal plane and pass through the bottom connector. The axial direction of the second reinforcing bars is parallel to the upper end face of the foundation base and perpendicular to the axial direction of the first reinforcing bars. The second reinforcing bars are located above the first reinforcing bars. The multiple second reinforcing bars are arranged parallel to each other along the horizontal plane and are located on both sides of the steel sleeve.

[0008] The principle of the aforementioned scheme is as follows: the seismic isolation structure is fixedly connected to the foundation through its bottom connecting body. The structure composed of the wooden partition, steel frame and top metal plate of the upper part of the seismic isolation structure constitutes a limiting structure to limit the connecting platform on the connecting structure. The upper end of the support column is used to connect the building structure. The externally cast structure is formed outside the seismic isolation structure to enhance the structural strength of the seismic isolation structure. During vibration, because the connecting structure is not rigidly connected to the isolation structure, it can move relative to the isolation structure, effectively reducing the transmission of vibration energy to the upper building. During vibration, due to the relatively low elastic modulus of the wooden partitions, they can absorb a large amount of vibration energy through deformation or even destruction. Furthermore, because the inner wall of the wooden partition is in contact with the outer wall of the connecting platform, it can respond to vibrations in multiple horizontal and vertical directions. Additionally, gaps exist between adjacent wooden partitions, and the isolation body formed by multiple wooden partitions can absorb a large amount of vertical vibration energy. On the other hand, multiple wooden partitions are connected together by connecting columns, bottom connectors, and a top metal plate. When a wooden partition is damaged under vibration, only the top metal plate and steel frame need to be removed to replace the internal wooden partition, effectively improving the convenience of post-earthquake repair.

[0009] In the aforementioned scheme, the first and second reinforcing bars are used to enhance the structural strength; the steel frame is used to maintain the gap between the wooden partitions and to facilitate the fabrication of the externally cast structure; and the steel frame is used to fill the gaps.

[0010] Preferably, the bottom connector consists of an upper plate and a lower plate; multiple supporting protrusions are formed on the upper surface of the lower plate, and the multiple channels formed by the multiple supporting protrusions match multiple first reinforcing bars; the lower plate is fixedly connected to the foundation base; the lower surface of the upper plate contacts the upper surface of the supporting protrusions; the edges of the upper plate and the lower plate are fixed by bolts. This preferred embodiment improves the ease of setting the first reinforcing bars and facilitates construction operations.

[0011] Preferably, the upper surface of the upper plate is provided with a groove; the upper surface of the upper plate contacts the lower surface of the bottom wooden partition; the area in the middle of the bottom surface of the groove forms a support area, and the area around the support area on the bottom surface of the groove forms a buffer zone; multiple hemispherical grooves are provided on the lower surface of the connecting platform corresponding to the support area, and the multiple hemispherical grooves are distributed in a matrix; a buffer ball is provided in each hemispherical groove, the lower end of the buffer ball contacts the support area, and the upper end of the buffer ball contacts the hemispherical groove; four limiting grooves are provided in the buffer zone, and the four limiting grooves are distributed circumferentially along the buffer zone; multiple buffer blocks are provided in a single limiting groove, and the upper end of the buffer block contacts the lower surface of the connecting platform; when no vibration occurs, the weight of the connecting platform is borne by multiple buffer balls, and the metal buffer blocks do not bear weight.

[0012] With the use of a buffer ball, vibration energy can be absorbed during vibration through the relative movement between the buffer ball and the hemispherical groove, as well as the relative movement between the buffer ball and the upper plate. Furthermore, since the hemispherical groove is a spherical structure, the connecting platform can more easily return to its original position under its own gravity after the buffer ball and the hemispherical groove are misaligned. With the use of a metal buffer block, the metal buffer block does not bear weight when there is no vibration. When vibration occurs, the vertical displacement of the connecting platform will collide with the metal buffer block and deform it, thereby absorbing vibration energy through the deformation of the metal buffer block. A single limiting groove can be formed by setting two parallel protrusions on the upper surface of the upper plate (the area between the two protrusions forms the limiting groove), and the limiting groove is used to prevent the metal buffer block from shifting.

[0013] The beneficial technical effects of this invention are: it proposes an enhanced vibration isolation component with a steel-wood hybrid structure, which can respond to vibrations in both the horizontal and vertical directions, effectively improves the vibration isolation effect of the vibration isolation component, and is easy to repair after an earthquake.
