Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a hybrid frame structure of load-bearing columns with built-in SRC columns and steel beams. Background Technology

[0002] SRC column-steel beam hybrid frame structure is a widely used structural form in modern architecture. This structure combines the advantages of concrete and steel, possessing both high load-bearing capacity and good seismic performance. SRC column-steel beam hybrid frame structure is particularly suitable for high-rise buildings that need to withstand large wind loads and seismic forces, effectively improving the safety and functionality of the original structure.

[0003] However, in actual use, the connection between the steel columns and steel beams of the SRC column-steel beam hybrid frame structure is relatively unstable. When the SRC column-steel beam hybrid frame structure is subjected to external forces, it may loosen, affecting the overall stability and safety of the structure. At the same time, when the SRC column-steel beam hybrid frame structure is subjected to strong earthquakes in actual use, it is prone to excessive deformation or damage. Utility Model Content

[0004] In response to the problems in related technologies, this utility model proposes a hybrid frame structure with built-in SRC column-steel beam for load-bearing columns, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A load-bearing column with built-in SRC column-steel beam hybrid frame structure includes a concrete main body. The inner wall of the concrete main body is provided with an installation component. The installation component includes a steel column and a reinforcing bar installed on the inner wall of the concrete main body. The surface of the steel column is provided with multiple fixing plates. The fixing plates and the reinforcing bar and the concrete main body are penetrated. Multiple fixing grooves are opened on the steel column. Multiple fixing blocks and multiple fixing blocks are installed on the inner wall of the fixing grooves respectively. One end of the inner wall of the fixing block is in contact with one end of the fixing block.

[0007] The surface of the mounting component is provided with a connecting component, which includes multiple connecting holes 1 opened on the steel column. The inner wall of the connecting hole 1 is provided with a steel bar 2. The surface of the steel bar 2 contacts one side of the fixing plate. Both ends of the steel bar 2 penetrate the concrete body. One end of the steel bar 2 passes through a connecting block. The surface of the connecting block contacts one side of the fixing plate and a steel beam. One end of the steel beam contacts the surface of the concrete body. Auxiliary components are installed on the concrete body and the connecting component.

[0008] Furthermore, in order to better install the SRC column-steel beam hybrid frame structure, the installation components also include fixing screws that are threadedly connected to fixing block two and fixing block one. One end of the fixing screw is threadedly connected to the inner wall of the fixing groove, and one side of fixing block one and fixing block two are fixedly connected to one side of the fixing plate.

[0009] Furthermore, in order to better connect and fix the SRC column-steel beam hybrid frame structure, the connection component also includes multiple connection holes 2 opened on the steel beam. The inner wall of the connection hole 2 is threaded with a connecting rod, and one end of the connecting rod is threaded to the fixing plate.

[0010] Furthermore, in order to better improve the stability of the joints of the SRC column-steel beam hybrid frame structure, the auxiliary components include multiple connection slots on the concrete main body and the steel beam. The inner wall of the connection slot is connected to the fixing plate. Connection plate one and connection plate two are respectively installed on the inner wall of the connection slot. One end of connection plate one is provided with a snap-fit ​​block, and one end of the snap-fit ​​block snaps into one end of connection plate two. Multiple mounting screws one are threadedly connected to connection plate one and connection plate two, and one end of mounting screw one is threadedly connected to the connection slot.

[0011] Furthermore, the connecting plate has multiple mounting screws 2 threadedly connected to it, with one end of each mounting screw 2 threadedly connected to the connecting plate 2.

[0012] Furthermore, in order to better improve the tightness between the second fixing block and the first fixing block, the inner wall of the second fixing block and one end of the first fixing block are respectively provided with a plurality of first limiting pieces and a plurality of second limiting pieces, with one end of the first limiting piece and one end of the second limiting piece in contact.

[0013] Furthermore, multiple fixing holes are provided on the fixing plate, and fixing screws are installed on the inner walls of the fixing holes.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting multiple fixing slots on the steel column and installing fixing block one and fixing block two in the fixing slots, and then fixing fixing block one and fixing block two in the fixing slots with fixing screws, a firm connection between the steel column and the fixing plate is ensured. The steel bar two and the connecting block in the connecting assembly make the connection between the steel beam and the steel column more stable, reducing the risk of loosening caused by external forces. At the same time, the overall stiffness and shear resistance of the structure are improved by setting multiple points of connection and multiple layers of fixing plates between the steel column and the steel beam, which can maintain good stability under strong earthquake action.

[0016] (2) By connecting the first and second connecting plates with the snap-fit ​​blocks and mounting screws, the seismic performance of the structure is further enhanced. The first and second connecting plates can be disassembled and assembled with simple tools, which further improves the convenience of maintenance and reduces construction time and cost.
