Description

Technical Field

[0001] This application relates to the technical field of steel structure beams and columns, and more specifically, to a steel structure beam and column connector with an adjustable clamping plate. Background Technology

[0002] Steel beam-column connectors are core node components of steel frame structures, responsible for transmitting shear force, axial force, and bending moment between beams and columns, ensuring overall structural stability and load-bearing capacity, transferring mechanical loads, effectively transferring the force of beams to columns, avoiding local stress concentration, ensuring node stiffness and ductility, balancing structural deformation and resistance to failure under load, achieving reliable beam-column connections, and adapting to installation and adjustment needs while simplifying construction processes. The clamping plates of steel beam-column connectors are core auxiliary components of bolted connection nodes, clamping the flanges or webs of beams and columns in conjunction with bolts to achieve load transfer and node fixation.

[0003] Regarding the aforementioned technologies, the inventors discovered that existing steel structure beam-column connector clamping plates, due to their inconvenience in adjustment, significantly increase construction difficulty and drastically reduce efficiency. They cannot compensate for component processing errors or installation misalignment; even slight misalignment makes it difficult for the clamping plate to fit properly, requiring additional grinding, hole enlargement, or even cutting, thus extending the construction period. With fixed hole diameters and bolt specifications, there is zero room for on-site adjustment. Any deviation in component position may lead to the scrapping of connectors, increasing material waste, causing stress imbalance at joints, highlighting safety hazards, reducing the overall bearing capacity of joints under load, weakening seismic and lateral displacement resistance, and reducing resistance to changes in working conditions, resulting in frequent later-stage failures. Temperature changes and vibration loads can cause minor deformations in the structure, which cannot be released through adjustment, easily leading to weld cracking and bolt fatigue damage.

[0020] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses a steel structure beam-column connector with an adjustable clamping plate. For example... Figure 1 As shown, it includes a transverse fixing frame 1, which is U-shaped. The height of the transverse fixing frame 1 is the same as the height of the central limiting plate 2. The U-shaped transverse fixing frame 1 can better contact the main body of the steel structure. The central limiting plate 2 is fixedly installed on the back of the transverse fixing frame 1. The central limiting plate 2 is C-shaped. Two sets of identical trapezoidal grooves 12 are provided in the middle of the inner side of the central limiting plate 2. Trapezoidal sliders 13 are slidably installed on the inner wall of the trapezoidal grooves 12. A central clamping plate 4 is fixedly installed at the end of the trapezoidal slider 13 away from the trapezoidal grooves 12. The inner side of the central clamping plate 4 is provided with anti-slip grooves. A through hole is provided in the middle of the central clamping plate 4. The central clamping plate 4 drives the trapezoidal slider 13 to slide inside the trapezoidal grooves 12. The movement trajectory of the central clamping plate 4 is restricted by the trapezoidal grooves 12 on the inner side of the central limiting plate 2, and it can slide stably. At the same time, it can adapt to steel structure beams and columns of more specifications and thicknesses.

[0023] Rectangular grooves 11 are provided at both ends of the central limiting plate 2 near the edge. Rectangular sliders 8 are slidably mounted on the inner wall of the rectangular grooves 11. A bolt rod 18 is rotatably mounted on the upper surface of the middle of the rectangular slider 8 via a bearing. A threaded sleeve 9 is threadedly connected to the middle of the bolt rod 18. The outer side of the threaded sleeve 9 is fixedly inserted into the top position of both ends of the central limiting plate 2. When the bolt rod 18 rotates under external force, the rectangular slider 8 at the bottom can move up and down due to the influence of the threaded sleeve 9, thereby causing the inner vertical fixing plate 3 to move up and down, achieving tight contact with the steel structure connector. A sliding plate 10 is fixedly mounted at one end of the rectangular slider 8. A pulley 16 is fixedly installed on the inner side of the part. The side of the pulley 16 away from the sliding plate 10 is slidably connected to the inner wall of the slide rail 15 at both ends of the middle limiting plate 2. The sliding plate 10 drives the pulley 16 to slide on the inner side of the slide rail 15. Under the action of the pulley 16, the outer sliding plate 10 can slide smoothly. A vertical fixing plate 3 is fixedly installed on the inner side of the sliding plate 10. The vertical fixing plates 3 are symmetrically arranged on the inner side of the middle limiting plate 2 and are both perpendicular to its inner side. The two vertical fixing plates 3 perpendicular to the middle limiting plate 2 can be set to accommodate more specifications of steel structure beams and columns and reduce the installation cost. The edge of the vertical fixing plate 3 is perpendicular to the inner side of the middle limiting plate 2.

[0024] A retaining plate 6 is fixedly installed on the outer side of the sliding plate 10. Identical blocking plates are fixedly installed on the upper and lower sides of the retaining plate 6. The ends of the blocking plates slide in contact with the outer side of the limiting slider 7. The blocking plates on both sides of the retaining plate 6 effectively engage the locking vertical plate 17, initially fixing the locking vertical plate 17 during installation to facilitate subsequent fixing work. A retaining groove 14 is fixedly installed in the middle of the retaining plate 6. The locking vertical plate 17 is slidably inserted into the inner wall of the retaining groove 14. Multiple identical limiting sliders 7 are fixedly installed on the outer side of the locking vertical plate 17. The limiting slider 7 is set as a semi-circle. A horizontal plate 5 is fixedly sleeved in the middle of the locking vertical plate 17. One end of the horizontal plate 5 is fixedly connected to the edge of the middle part of the horizontal fixing frame 1. The locking plate 6 is subjected to force on the sliding rod on the outside of the locking vertical plate 17. The locking groove 14 is gradually locked with the outside of the limiting slider 7. The movement speed of the locking plate 6 is limited by the limiting slider 7, which plays a buffering role. A collar 19 is fixedly sleeved on the top of the locking vertical plate 17. One end of the collar 19 is fixedly connected to the top of the outside of one end of the middle limiting plate 2.

[0025] The implementation principle of a steel structure beam-column connector with an adjustable clamping plate in this application embodiment is as follows: The transverse fixing frame 1 adopts a "U"-shaped structure, and its height is consistent with the middle limiting plate 2, which can form a large-area close contact with the main body of the steel structure, providing a stable installation foundation for the entire connector. The middle limiting plate 2 is fixed to the back of the transverse fixing frame 1 in a "C" shape, which not only provides an installation carrier for subsequent adjustment components, but also adapts its shape to the beam-column contour, initially limiting the offset of the connection position. When the upper surface of the rectangular slider 8 is rotated, the bolt rod 18 connected by the bearing forms a threaded transmission with the threaded sleeve 9 fixedly inserted at the top of both ends of the middle limiting plate 2. Under the action of the thread, the rectangular slider 8 moves up or down or translates along the rectangular groove 11, thereby driving the sliding plate 10 and the vertical fixed plate 3 to move synchronously, so as to achieve precise adjustment of the distance between the two vertical fixed plates 3, so as to adapt to steel structure beams and columns of different widths and ensure that the vertical fixed plate 3 fits tightly with the side of the beam and column. Trapezoidal sliders 13 are slidably installed in the two sets of trapezoidal grooves 12 in the middle of the inner side of the central limiting plate 2. The end of the trapezoidal slider 13 away from the trapezoidal groove 12 is fixed to the central clamping plate 4. The central clamping plate 4 can slide along the trapezoidal groove 12 with the trapezoidal slider 13 and adjust its position according to the thickness of the steel structure beam and column to achieve precise fit with the upper and lower surfaces of the beam and column. It is suitable for beams and columns of various thicknesses. The inner side of the central clamping plate 4 is provided with anti-slip grooves, which can increase the friction with the surface of the beam and column after fit and prevent relative sliding after installation. The through hole in the middle can be used with fasteners to further reinforce the joint, improve the stability of the node connection, and prevent displacement under load. The snap-fit ​​vertical plate 17 is fixed to the middle edge of one side of the horizontal fixing frame 1 via the horizontal plate 5. Its top is connected to the top of the outer side of one end of the middle limiting plate 2 via the collar 19, forming a stable support structure. The snap-fit ​​plate 6 fixed to the outside of the sliding plate 10 has a central snap-fit ​​groove 14 that slides into the snap-fit ​​vertical plate 17. Multiple semi-circular limiting sliders 7 on the outside of the snap-fit ​​vertical plate 17 gradually snap into the groove 14 as the snap-fit ​​plate 6 slides, limiting the movement speed of the snap-fit ​​plate 6 and playing a buffering role to avoid damage to the parts due to excessive adjustment. The blocking plates on the upper and lower sides of the snap-fit ​​plate 6 slide in contact with the outer side of the limiting sliders 7, which can form a preliminary snap-fit ​​fixation for the snap-fit ​​vertical plate 17. Before the vertical fixing plate 3 is adjusted to the position, the relative position of the parts is stable, which facilitates subsequent precise fastening. By adjusting the distance of the vertical fixing plate 3 and adapting the thickness of the central clamping plate 4, all contact points of the connectors are made to fit tightly with the steel structure beams and columns, avoiding stress concentration caused by "loose connections". The tightening force of the bolt rod 18 is transmitted to the vertical fixing plate 3 through the rectangular slider 8 and the sliding plate 10. The pressure of the central clamping plate 4 is transmitted to the central limiting plate 2 through the trapezoidal slider 13. Finally, all forces are evenly transmitted through the overall frame formed by the transverse fixing frame 1 and the central limiting plate 2, ensuring the force balance of the nodes and improving the overall stability and load-bearing capacity of the steel structure.
