Description

Technical Field

[0001] The present application belongs to the technical field of steel structures, and specifically relates to a steel structure column. Background Art

[0002] In modern construction projects, steel columns are widely used in the main structures of various buildings due to their high strength, light weight, and fast construction speed, especially in high-rise buildings, large-span buildings, and construction projects in earthquake zones. The use of steel columns can not only improve the structural stability and safety performance of buildings, but also meet the needs of buildings in terms of beauty, practicality, and environmental protection.

[0003] Steel columns have many advantages as mentioned above, but their poor shock absorption performance when dealing with dynamic loads such as earthquakes has become a prominent problem. Due to the high elastic modulus of steel itself, the energy absorption and dissipation capacity of steel columns is limited when subjected to earthquake impacts, resulting in a large amount of vibration energy directly acting on the structure, which is easy to cause local or overall damage to the column, and even cause the collapse of the entire building. Under the action of earthquakes, the poor shock absorption performance of steel columns is mainly reflected in the following aspects: 1. Due to the large overall stiffness of the steel structure, once it is subjected to an earthquake impact, its internal stress is concentrated, and it is difficult to effectively disperse the earthquake energy, making the column prone to damage at weak points; 2. Steel columns are prone to buckling instability under earthquakes, especially when the axial pressure is relatively large. Buckling instability will greatly reduce the bearing capacity and seismic performance of the structure; 3. Due to the stiffness matching problem at the connection between the steel column and other structural elements, stress concentration is easy to occur at the connection, which in turn causes damage or fracture at the connection, affecting the stability of the entire structure. Summary of the invention

[0004] The present application provides a steel structure column to solve the problem of internal stress concentration of the steel structure column under earthquake impact.

[0005] The technical solution adopted in this application is:

[0006] A steel structure column comprises a main column body, which is a columnar structure with parallel fins on both sides connected by an intermediate connecting plate. A plurality of support frames evenly arranged up and down are arranged inside the main column body, and the support frames are composed of cross-arranged reinforcement beams and symmetrically arranged on both sides of the intermediate connecting plate. The support frames are connected to the two fins through adjustable connecting pieces at both ends, and a shock absorber is fixedly arranged between the intermediate connecting plate and the support frames; joint plates are provided at the top and bottom of the main column body, and a plurality of main columns are connected and fixed up and down through the joint plates to form a steel structure column.

[0007] Optionally, a plurality of evenly distributed transverse support rods are further provided inside the main column, with both ends connecting the two fins. The transverse support rods are symmetrically distributed on both sides of the middle connecting plate and are arranged on the side away from the support frame.

[0008] Optionally, two pairs of fixing frames perpendicular to the fin are symmetrically installed on the inner side surface of the fin, and the two pairs of fixing frames are symmetrically positioned relative to the middle connecting plate, and both ends of the support frame are movably hinged to the opposite fixing frames.

[0009] Optionally, the joining plate is a horizontal frame-shaped fin that surrounds the outer side of the main column and is cast integrally with the main column, and the frame-shaped fin is provided with a plurality of symmetrically distributed reserved connection holes.

[0010] Optionally, the bonding plate is a first bonding plate which is arranged on both symmetrical sides of the fin and perpendicular to the outer plate surface of the fin. The end of the first bonding plate is flush with the end of the main column. A plurality of threaded holes are arranged on the first bonding plate. The ends of the second bonding plates on adjacent main columns are connected. Mounting plates are respectively arranged on both sides of the first bonding plate and the second bonding plate. Fixing holes corresponding to the threaded holes on the first bonding plate and the second bonding plate are arranged on the mounting plates. The mounting plates are fixed to the first bonding plate and the second bonding plate by connecting the threaded holes and the fixing holes with bolts.

[0011] Optionally, a main column connected to the building base is provided with reinforcing ribs on the outside, the reinforcing ribs are arranged along the circumference of the main column, and the reinforcing ribs are fixedly connected to the main column.

[0012] Optionally, the upper end surface of the middle connecting plate is recessed downward to form a recessed space, and a plurality of energy dissipators are arranged in the recessed space. The energy dissipators are composed of metal yield components, and the energy dissipators are connected to the inner wall of the recessed space by a replaceable connection method.

[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0014] 1. By setting a support frame inside the main column, the support frame can absorb and dissipate the energy generated by dynamic loads such as earthquakes, preventing these energies from directly acting on the main structure, thereby reducing the damage to the building caused by vibration; at the same time, it is conducive to controlling the displacement of the main column during an earthquake, reducing the overall displacement and sway of the steel structure column, and improving the stability of the overall structure; reducing the stress concentration caused by dynamic loads such as earthquakes, effectively preventing damage to key connection parts of steel structure columns, and reducing the risk of collapse caused by structural damage.

[0015] 2. By setting joint plates at the top and bottom of the main column, the structural stability of the steel structure column during installation can be improved. The joint plates can effectively control the lateral and longitudinal displacement of the main column, reduce the risk of structural instability caused by excessive displacement, and improve the overall stability and safety of the structure.

[0027] Furthermore, a plurality of evenly distributed transverse support rods 5 are provided inside the main column 1 and are connected to the two fins 11 at both ends. The transverse support rods 5 are symmetrically distributed on both sides of the middle connecting plate 12 and are arranged on the side away from the support frame 2 .
