Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a connection component for a semi-rigid steel frame. Background Technology

[0002] Semi-rigid steel frame connection components, as key parts connecting beams and columns in steel structure buildings, play an important role in the field of building structural engineering. Through reasonable structural design, the connection nodes can both transmit a certain bending moment and allow a certain degree of relative rotation between components, thereby balancing the load-bearing capacity and deformation requirements of the structure.

[0003] 1. Beam end connection plate: It is mostly made of high-strength steel plate and installed at the end of the beam. It has bolt holes for connecting with other components and is the basic component for connecting beams and columns.

[0004] 2. Column end connection plate: Corresponding to the beam end connection plate, it is installed at the corresponding position of the column. It is also connected to the beam end connection plate and other components through bolt holes to jointly bear the load transmitted by the beam.

[0005] 3. High-strength bolts: As key components connecting beam end plates and column end plates, they have high tensile and shear strength, and when tightened to a specified torque, they ensure the reliability and tightness of the connection.

[0006] Currently, various forms and methods are used in engineering to achieve the performance of semi-rigid steel frame connection components. Some connection components adopt the traditional welding and bolt hybrid connection method, in which the components are prefabricated by welding in the factory and then assembled on site using bolts; others use flexible node connection components, which use special elastic elements to achieve the semi-rigid characteristics of the connection nodes; in addition, there are also prefabricated modular connection components, which are designed as standardized modules to improve construction efficiency.

[0007] However, the above-mentioned implementation methods still have the following problems: In the traditional welding and bolt hybrid connection method, the welding process is prone to residual stress and deformation, affecting the overall performance of the structure. Furthermore, the on-site welding workload is large, construction efficiency is low, and quality is difficult to guarantee. The elastic elements in the flexible node connection components are prone to fatigue damage under long-term loads, reducing the service life of the connection components. Moreover, their load-bearing capacity is limited, making it difficult to meet the needs of large-span, heavy-load steel structures. At the same time, in terms of seismic performance, existing connection components cannot fully utilize structural deformation to dissipate seismic energy, and are difficult to effectively adapt to foundation changes during uneven settlement. This application proposes a solution to this problem: a semi-rigid steel frame connection component with triangular composite connections and frame beam mortise and tenon joints. This component can enhance structural stability and seismic performance, facilitate construction and maintenance, optimize material use, and reduce costs. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a connection component for a semi-rigid steel frame. It solves the problems of residual stress and deformation easily generated during the welding process in traditional welded bolt hybrid connection methods, which affect the overall performance of the structure. In addition, the on-site welding workload is large, the construction efficiency is low, and the quality is difficult to guarantee. Furthermore, the elastic elements in the flexible node connection component are prone to fatigue damage under long-term load, which reduces the service life of the connection component.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A semi-rigid steel frame connection component includes a frame column, with connecting beam three on both the left and right sides of the frame column. Connecting beam one is provided on the upper surface of each of the two connecting beam threes, and connecting beam two is provided on the lower surface of each of the two connecting beams. Triangular reinforcing ribs are fixedly connected to the opposite surfaces of the two connecting beam twos. A set of limiting blocks is fixedly connected to the surfaces of the two connecting beam threes and the two connecting beam twos. Two steel plates are fixedly connected to the front and rear sides of the two connecting beam ones and the two connecting beam twos by nuts.

[0011] Preferably, the two triangular reinforcing ribs are tightly fitted to the two connecting beams one and two connecting beams three, respectively, and a set of limiting grooves are provided on the surfaces of the two connecting beams one and two connecting beams two.

[0012] Preferably, a set of the limiting grooves are movably engaged with a set of limiting blocks, and the frame column is fixedly connected to two connecting beams one and two connecting beams three by angle steel.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The stability of the overall triangle shape gives the triangular frame beam good resistance to deformation, effectively distributing loads and reducing stress concentration. The combination of mortise and tenon joints and triangular stiffeners further enhances the strength and integrity of the frame beam. The interlocking action of the mortise and tenon joints can improve the beam's shear resistance, while the triangular stiffeners can provide additional support inside the beam, improving its bending resistance. This allows the entire steel frame structure to withstand greater loads, improving the structure's stability and safety.

[0015] 2. The characteristics of semi-rigid connections and the flexibility of mortise and tenon connections enable frame columns to dissipate seismic energy through their own deformation under dynamic loads such as earthquakes. The synergistic effect of triangular frame beams and mortise and tenon connections can produce more uniform deformation of the structure during earthquakes, avoiding local weak points. Mortise and tenon connections can generate a certain amount of friction and slippage during earthquakes, dissipating seismic energy, reducing earthquake damage to the structure, and improving the seismic performance of the structure.

[0022] This application provides a semi-rigid steel frame connection component that effectively solves the problems of residual stress and deformation during welding in traditional welded bolt hybrid connection methods, which affect the overall performance of the structure. Furthermore, it addresses the issues of large on-site welding workload, low construction efficiency, and difficulty in ensuring quality.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of traditional welded bolt hybrid connection methods, such as the easy generation of residual stress and deformation during the welding process, which affects the overall performance of the structure, large on-site welding workload, low construction efficiency, and difficulty in ensuring quality, and the easy occurrence of fatigue damage in the elastic elements of the flexible node connection assembly under long-term load, which reduces the service life of the connection assembly. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a connection component for a semi-rigid steel frame, including a frame column 1. Connecting beams 6 are provided on both the left and right sides of the frame column 1. Connecting beams 2 are provided on the upper surfaces of the two connecting beams 6, and connecting beams 3 are provided on the lower surfaces of the two connecting beams 2. Triangular reinforcing ribs 4 are fixedly connected to the opposite surfaces of the two connecting beams 3 and 6. A set of limiting blocks 8 are fixedly connected to the surfaces of the two connecting beams 2 and 3. Two steel plates 5 are fixedly connected to the front and rear sides of the two connecting beams 2 and 3 by nuts. When the frame column 1 bears a load, the external force will act on the frame beams. Since the frame beams are designed with mortise and tenon joints composed of connecting beams 2, 3, and 6, the load will be transferred along the various parts of the triangular frame beams. The beams are connected by mortise and tenon joints using the limiting blocks 8 and limiting grooves 7. Connections enable close cooperation between different parts of the beam, effectively transferring loads from one component to another. Simultaneously, the triangular stiffeners 4 enhance the overall strength and rigidity of the frame beam, allowing it to better withstand loads and reduce deformation. The connecting components, via steel plates 5 and nuts, connect and fix the frame beam to other components, ensuring effective load transfer throughout the steel frame structure and maintaining structural stability. The semi-rigid triangular combination connection allows for relative rotation and deformation to a certain extent. Under load, the triangular shape of the frame beam and the mortise and tenon connection design can adapt to structural deformation within a certain range, coordinating deformation between different parts of the frame beam and between the frame column 1 and other components. The flexibility of the mortise and tenon connection provides a buffer during structural deformation, preventing connection failure or structural failure due to excessive local deformation.

[0026] Two triangular reinforcing ribs 4 are tightly fitted to two connecting beams 1-2 and 2-3-6 respectively. Each of the two connecting beams 1-2 and 2-3 has a set of limiting grooves 7, which are movably engaged with a set of limiting blocks 8. The frame column 1 is fixedly connected to the two connecting beams 1-2 and 2-3-6 by angle steel. The overall triangular stability gives the triangular frame beam good resistance to deformation, effectively distributing loads and reducing stress concentration. The combination of mortise and tenon joints and triangular reinforcing ribs 4 further enhances the strength and integrity of the frame beam. The interlocking action of the mortise and tenon joints improves the beam's shear resistance, while the triangular reinforcing ribs... The reinforcing rib 4 provides additional support inside the beam, improving its bending resistance and enabling the entire steel frame structure to withstand greater loads, thus enhancing its stability and safety. The semi-rigid connection and the flexibility of the mortise and tenon joint allow the frame column 1 to dissipate seismic energy through its own deformation under dynamic loads such as earthquakes. The synergistic effect of the triangular frame beam and the mortise and tenon joint allows the structure to undergo more uniform deformation during earthquakes, avoiding local weak points. The mortise and tenon joint can generate a certain amount of friction and slippage during earthquakes, dissipating seismic energy, reducing earthquake damage to the structure, and improving the structure's seismic performance.

[0027] Among them, frame column 1 is the main supporting component of the connecting components. It is connected to connecting beam 1 2 and connecting beam 3 6 on the left and right sides, bears the load and transmits the force from the frame beam to the foundation, maintaining the vertical stability of the entire steel frame structure.

[0028] Connecting beam 12 is located on the upper surface of connecting beam 36 and the lower surface of connecting beam 23. It is a component of the frame beam and works in conjunction with other beams through mortise and tenon joints. While transferring loads, it participates in the stress and deformation of the frame beam as a whole, thereby enhancing the structural stability.

[0029] Connecting beam 2 3 is located below connecting beam 1 2, and its opposite face is fixed with triangular reinforcing rib 4. It is connected to other beams by mortise and tenon joints. During the load transfer process, it together with connecting beam 1 2 and connecting beam 3 6 to form a stable structure and improve the overall load-bearing capacity of the frame beam.

[0030] The triangular reinforcing rib 4 is fixed to the opposite side of the connecting beam 2 3 and fits tightly with the connecting beam 1 2 and the connecting beam 3 6. It can enhance the strength and stiffness of the frame beam, provide additional support, improve the beam's bending resistance, and reduce deformation.

[0031] Steel plate 5 is fixed to the front and rear sides of connecting beam 1 2 and connecting beam 2 3 by nuts, which is used to connect and fix the frame beam with other components, ensuring that the load is effectively transferred in the entire steel frame structure and ensuring the reliability of the structural connection.

[0032] Connecting beam 3 6 is located above the left and right sides of frame column 1, and together with connecting beam 1 2 and connecting beam 2 3, it forms a triangular frame beam, which participates in load transfer and structural stress, and uses the stability of triangle to enhance the deformation resistance of the entire frame beam.

[0033] The limiting groove 7 is opened on the surface of connecting beam 1 2 and connecting beam 2 3, and is movably engaged with the limiting block 8 to form a mortise and tenon connection structure, so that the various parts of the beam fit together tightly, ensuring the relative position of each beam is stable when the load is transferred, and coordinating structural deformation.

[0034] The limiting block 8 is fixed on the surface of connecting beam 3 6 and connecting beam 2 3, and cooperates with the limiting groove 7 to realize the mortise and tenon connection between the beams, improve the shear resistance of the beams, prevent excessive displacement between beams when the structure is under stress, and maintain the integrity of the frame beam.

[0035] Working principle:

[0036] When frame column 1 bears a load, the external force will act on the frame beam. Since the frame beam is designed with mortise and tenon joints, consisting of connecting beams 2, 3, and 6, the load will be transferred along the various parts of the triangular frame beam. The beams are connected by mortise and tenon joints using limiting blocks 8 and limiting grooves 7, ensuring a tight fit between the beam parts and effectively transferring the load from one component to another. Simultaneously, the triangular reinforcing ribs 4 enhance the overall strength and stiffness of the frame beam, enabling it to better bear the load and reduce deformation. The connecting components use steel plates 5 and nuts to connect and fix the frame beam to other components, ensuring that the load can be effectively transferred throughout the steel frame structure, maintaining structural stability. The semi-rigid triangular combination connection allows for relative rotation and deformation to a certain extent. Under load, the triangular shape and mortise and tenon joint design of the frame beam can adapt to structural deformation within a certain range, coordinating the deformation between the various parts of the frame beam and between frame column 1 and other components. The flexibility of the mortise and tenon joints allows for better structural deformation during deformation. Providing a certain buffer to avoid connection failure or structural failure due to excessive local deformation, the overall triangular stability gives the triangular frame beam good resistance to deformation, effectively distributing loads and reducing stress concentration. The combination of mortise and tenon joints and triangular reinforcing ribs 4 further enhances the strength and integrity of the frame beam. The interlocking action of the mortise and tenon joints can improve the beam's shear resistance, while the triangular reinforcing ribs 4 can provide additional support inside the beam, improving its bending resistance. This allows the entire steel frame structure to withstand greater loads, improving the structure's stability and safety. The semi-rigid connection characteristics and the flexibility of the mortise and tenon joints allow the frame column 1 to dissipate seismic energy through its own deformation under dynamic loads such as earthquakes. The synergistic effect of the triangular frame beams and mortise and tenon joints can produce more uniform deformation of the structure during earthquakes, avoiding local weak points. The mortise and tenon joints can generate a certain amount of friction and slippage during earthquakes, dissipating seismic energy, reducing earthquake damage to the structure, and improving the structure's seismic performance.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
