Description

Technical Field

[0001] This utility model relates to the field of seismic isolation column technology, and in particular to a hollow steel-concrete seismic isolation column. Background Technology

[0002] Seismic isolation columns are important components widely used in building engineering and other fields. They are mainly used to isolate or reduce the transmission of seismic energy to the upper structure by installing seismic isolation devices between the foundation and the superstructure. Common types of seismic isolation columns include rubber seismic isolation columns and sliding seismic isolation columns. Although these types of seismic isolation columns improve the seismic performance of building structures to a certain extent, they still have many shortcomings in terms of energy dispersion capacity, adaptability, economy, and durability.

[0003] Hollow-core steel-concrete composite columns are a type of composite structural column, mainly composed of steel sections (such as I-beams and channel steel) and concrete. Their hollow interior structure allows for sufficient load-bearing capacity while reducing weight. Compared to solid steel-concrete composite columns, the hollow design saves materials and reduces costs, while also exhibiting better performance in energy dissipation, adaptability, and durability. Combining hollow-core steel-concrete composite columns with seismic isolation devices and designing them as seismic isolation columns can effectively solve the problems of insufficient energy dissipation, adaptability, economy, and durability in existing seismic isolation columns. However, no relevant technology has been found in the prior art. Therefore, this application proposes a hollow-core steel-concrete composite seismic isolation column. Utility Model Content

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figure 1-2 As shown, a hollow steel-concrete seismic isolation column includes a concrete base 1, a rubber seismic isolation bearing 2, a steel frame 3, and a concrete column body 4.

[0031] The concrete base 1 is set horizontally, the rubber seismic isolation bearing 2 is installed on the top surface of the concrete base 1, the steel frame 3 is a square frame structure with open ends, and is installed vertically on the top surface of the rubber seismic isolation bearing 2. The concrete column 4 covers the outside of the steel frame 3.

[0032] The rubber seismic isolation bearing 2 is connected to the concrete base 1 via a first connecting assembly. This first connecting assembly includes several first bolts 8, several first pre-embedded anchor bars 5, several first straight threaded sleeves 6, and a first connecting plate 7. The first pre-embedded anchor bars 5 are vertically arranged within the concrete base 1 and connected to the first connecting plate 7 via the first straight threaded sleeves 6. Preferably, the first straight threaded sleeves 6 are welded to the first connecting plate 7. The first connecting plate 7 is located on the top surface of the concrete base 1, and the rubber seismic isolation bearing 2 is placed on the top surface of the first connecting plate 7. The several first bolts 8 movably pass through the bottom of the rubber seismic isolation bearing 2 and the first connecting plate 7, and are threadedly connected to the several first straight threaded sleeves 6 respectively. The several first bolts 8 are arranged around the centerline of the rubber seismic isolation bearing 2.

[0033] The rubber seismic isolation bearing 2 is connected to the steel frame 3 via a second connecting assembly. The second connecting assembly includes several second bolts 12, several second pre-embedded anchor bars 9, several second threaded sleeves 10, and a second connecting plate 11. The several second pre-embedded anchor bars 9 are located within the concrete column 4 above the rubber seismic isolation bearing 2 and are connected to the second connecting plate 11 via several second threaded sleeves 10. Preferably, the second threaded sleeves 10 are welded to the second connecting plate 11. The second connecting plate 11 is located on the top surface of the rubber seismic isolation bearing 2. The several second bolts 12 movably pass through the top of the rubber seismic isolation bearing 2 and the second connecting plate 11, and are threadedly connected to the several second threaded sleeves 10 respectively. The several second bolts 12 are arranged around the centerline of the rubber seismic isolation bearing 2.

[0034] In this embodiment, both the first bolt 8 and the second bolt 12 are high-strength bolts, and both the first straight-threaded sleeve 6 and the second straight-threaded sleeve 10 are high-strength straight-threaded sleeves. The first embedded anchor bar 5 and the second embedded anchor bar 9 are both L-shaped. There are eight of each: the first bolt 8, the second bolt 12, the first straight-threaded sleeve 6, the second straight-threaded sleeve 10, the first embedded anchor bar 5, and the second embedded anchor bar 9. The bottom and top surfaces of the rubber vibration isolation bearing 2, the first connecting plate 7, and the second connecting plate 11 are all square, with two through holes for bolts to pass through at each corner of the square. Two first embedded anchor bars 5 located on the same side of the square are arranged opposite each other, and two second embedded anchor bars 9 located on the same side of the square are also arranged opposite each other.

[0035] The bottom of the steel frame 3 is welded to the second connecting plate 11, and eight second pre-embedded anchor bars 9 form a limiting structure for limiting the lower end of the steel frame 3. The steel frame 3 includes four vertically arranged angle steels 13, which serve as the four long sides of the square frame structure. Several web members 14 are connected between adjacent angle steels 13. The bottom of the angle steels 13 is welded to the second connecting plate 11, and the angle steels 13 are welded and fixed to the web members 14. In this embodiment, fourteen web members 14 are connected between adjacent angle steels 13.

[0036] The steel frame 3 not only provides the necessary load-bearing capacity but also enhances the overall performance of the seismic isolation column through its synergy with the concrete. The concrete fills the area around the steel frame 3, working together to form the main structure of the steel-concrete seismic isolation column. The presence of concrete not only increases the stiffness and load-bearing capacity of the seismic isolation column but also improves its integrity and seismic performance through its bonding with the steel frame 3. High-strength bolts provide rigid connections within the seismic isolation column, ensuring close coordination between the steel frame 3 and the concrete column 4, and between the rubber seismic isolation bearing 2 and the concrete base 1.

[0037] The steel frame 3 of this utility model adopts a hollow design. Its dual constraint with concrete improves the seismic performance of the structure. The cavity of the steel frame 3 can absorb seismic energy and reduce the vibration amplitude of the building, thereby effectively protecting the safety of the building.

[0038] The construction process of this utility model is relatively simple, and it can adopt a modular design, which allows for fast on-site construction and helps to shorten the overall construction cycle. This structural form is suitable for various environmental and terrain conditions and can be flexibly adjusted according to different design requirements, thus having strong adaptability.

[0039] The steel frame 3 of this utility model adopts a hollow design, which reduces the structural weight, reduces the amount of foundation settlement, saves steel consumption, and reduces construction costs. In addition, the fast construction speed also helps to reduce the overall construction cost.

[0040] In this invention, the steel frame 3 and concrete work together to bear the external load. The high strength of the steel frame 3 ensures the load-bearing capacity of the structure, while the filling of concrete improves the deformation capacity of the structure, making the overall structure more stable and reliable, improving the durability of the building, and extending its service life.
