Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a vibration damping structure for building frame beam joints. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are primarily composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates. Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings.

[0003] Currently, during the construction of steel structures, connection nodes are used at the joints of frame beams to connect them. To achieve rapid connection between frame beams, connecting components are required. Therefore, the quality of these connecting components directly affects the safety of the entire steel structure.

[0004] Regarding the aforementioned technologies, the inventors believe that existing connecting components typically employ a hard connection method with intersecting nodes, resulting in direct hard contact between the connecting components and the frame beams. This makes them prone to damage under vibration conditions, which can affect the quality of the steel structure. Utility Model Content

[0005] To improve the seismic resistance of frame beam joints, this application provides a seismic damping structure for building frame beam joints.

[0006] The technical solution for a building frame beam joint damping structure provided in this application is as follows: A vibration damping structure for a building frame beam joint includes a connecting vertical rod, a connecting horizontal rod, a connecting sleeve rod, and a damping component. The connecting vertical rod and the connecting horizontal rod are both square rods. The connecting sleeve rod is a square hollow rod. The connecting sleeve rod is horizontally connected to the vertical side wall of the connecting vertical rod. One end of the connecting horizontal rod is inserted into the connecting sleeve rod. The inner cross-section of the connecting sleeve rod is larger than the longitudinal cross-section of the connecting horizontal rod. The connecting sleeve rod and the connecting horizontal rod are connected by a connector. The damping component is disposed within the connecting sleeve rod. The damping component includes damping blocks and damping rods. Two damping blocks are disposed within the connecting sleeve rod, with the two damping blocks respectively disposed on opposite sides of the vertically opposite connecting horizontal rod. The damping rods are connected to the damping blocks. The upper damping rod is connected to the inner top wall of the connecting sleeve rod, and the lower damping rod is connected to the inner bottom wall of the connecting sleeve rod.

[0007] By adopting the above technical solution, when the connecting crossbar sways vertically within the connecting sleeve, the two damping blocks abut against the side wall of the connecting crossbar via damping rods, thus mitigating the vibration generated by the connecting crossbar. Through the mutual cooperation of the connecting vertical bar, connecting crossbar, connecting sleeve, and damping components, a damping connection between the connecting vertical bar and connecting crossbar is achieved, which improves the seismic resistance of the frame beam joint.

[0008] Optionally, the damping assembly further includes a compression block, a slide bar, a sliding block, and a damping spring. One compression block is provided on the top and bottom surfaces of the connecting crossbar within the connecting sleeve. The length direction of the compression block is consistent with the length direction of the connecting crossbar. Two slide bars are arranged parallel to each other along their length direction within the connecting sleeve, respectively positioned on opposite sides of the vertical direction of the connecting crossbar. Two sliding blocks are slidably disposed on each slide bar, with the two sliding blocks on the same slide bar located at opposite ends of the corresponding compression block along its length direction. An abutment slope is provided on the side of the sliding block closest to the compression block, and compression slopes corresponding to the shape of the abutment slope are provided at both ends of the compression block along its length direction. The damping spring connects the two sliding blocks on the same slide bar, and the abutment slope of the sliding block slides and engages with the compression slope of the compression block under the action of the damping spring.

[0009] By adopting the above technical solution, when the connecting crossbar moves towards the two sliding blocks on one side, the two pressing inclined surfaces of the pressing block and the abutting inclined surfaces of the two sliding blocks slide relative to each other, realizing synchronous driving of the two sliding blocks. The two sliding blocks slide along the slide bar in a direction away from each other. The damping spring stretches and accumulates elastic potential energy. Under the action of the damping spring, the sliding blocks apply a reverse force to the pressing block, which helps the connecting crossbar to return to the middle position more quickly.

[0010] Optionally, a connecting block is provided on the side of each of the two sliding blocks on the same slide rod that are close to each other. A push block is connected to the end of the connecting block away from the sliding block. The push block is disposed between the inner wall of the damping block and the connecting sleeve rod. A first push slope is provided on the end of the push block that is close to the damping block. The first push slope is oriented toward the corresponding sliding block. Two second push slopes are provided on the side of the damping block that is away from the connecting crossbar. The two push slopes are provided one-to-one with the first push slopes on the two push blocks. The first push slopes slide and fit with the corresponding second push slopes.

[0011] By adopting the above technical solution, when the two sliding blocks on one side of the connecting crossbar approach each other, the two sliding blocks move away from each other under the squeezing action of the squeezing block. The first propulsion ramps on the two propulsion blocks simultaneously slide relative to the second propulsion ramps on the damping block. The damping block moves towards the connecting crossbar under the propulsion of the propulsion blocks, squeezing it and helping the connecting crossbar return to a stable and centered state more quickly.

[0012] Optionally, an abutment block is provided on the side of the shock-absorbing block near the connecting crossbar, and an abutment spring is connected between the abutment block and the shock-absorbing block. The abutment block abuts against the side wall of the connecting crossbar under the action of the abutment spring.

[0013] By adopting the above technical solution, the setting of the abutment block and the abutment spring avoids the damping block from directly contacting the surface of the connecting crossbar, which could lead to excessive surface pressure and deformation damage.

[0014] Optionally, the connector includes a connecting bolt and a connecting nut. The top and bottom surfaces of the connecting sleeve are provided with connecting waist-shaped holes along their length. The connecting bolt passes through the connecting waist-shaped holes and the connecting sleeve. The connecting bolt passes through the connecting crossbar and is slidably connected to it. One end of the connecting bolt extending out of the connecting sleeve is connected to the connecting nut.

[0015] By adopting the above technical solution, the connecting bolts and nuts enable a detachable connection between the connecting sleeve and the connecting crossbar. The oblong hole allows the connecting crossbar to slide slightly along its length within the connecting sleeve, reducing the possibility of damage to the connecting crossbar and connectors due to rigid connections during the connection process.

[0016] Optionally, the connecting sleeve is provided with an end damping plate inside, one side of the end damping plate is connected to the connecting vertical rod, and the other side of the end damping plate abuts against the end of the connecting horizontal rod.

[0017] By adopting the above technical solution, the end damping plate provides shock absorption to the ends of the connecting crossbars and between the connecting vertical bars.

[0018] Optionally, a side damping plate is provided on each of the two horizontally opposite inner walls of the connecting sleeve rod, and the side damping plate is fitted to the side wall of the connecting crossbar.

[0019] By adopting the above technical solution, the side damping plate provides shock absorption to both sides of the connecting crossbar in the horizontal direction.

[0020] Optionally, a sealing rubber ring is provided at the end of the connecting sleeve rod away from the connecting vertical rod, and the inner ring wall of the sealing rubber ring abuts against the peripheral wall of the connecting horizontal rod.

[0021] By adopting the above technical solution, the sealing rubber ring is placed between the open end of the connecting sleeve rod and the peripheral wall of the connecting crossbar, thereby sealing the internal space of the connecting sleeve rod and reducing the possibility of dust and moisture from the external environment entering the connecting sleeve rod.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the cooperation of connecting vertical bars, connecting horizontal bars, connecting sleeve bars and damping components, damping connection between connecting vertical bars and connecting horizontal bars is achieved, which has the effect of improving the seismic resistance of frame beam joints; 2. The shock absorption components help the connecting crossbar return to its center position more quickly; 3. The design of the abutment block and abutment spring avoids the shock absorber block from directly contacting the surface of the connecting crossbar, which could lead to excessive surface pressure and deformation damage.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be further described in detail below. Embodiments of this application provide a seismic damping structure for a building frame beam joint, which improves the seismic resistance of the frame beam joint.

[0028] Reference Figure 1 and Figure 2A vibration damping structure for a building frame beam node includes a connecting vertical rod 1, a connecting horizontal rod 2, a connecting sleeve rod 3, and a damping component 4. Both the connecting vertical rod 1 and the connecting horizontal rod 2 are square rods, and the connecting sleeve rod 3 is a square sleeve rod. The connecting vertical rod 1 is vertically positioned, and the connecting sleeve rod 3 is horizontally fixed to one side of the connecting vertical rod 1. One end of the connecting horizontal rod 2 is inserted into the connecting sleeve rod 3. The top and bottom surfaces of the connecting sleeve rod 3 have corresponding connecting oblong holes 31 along its length. A connecting bolt 5 is vertically inserted into the connecting oblong hole 31. The section of the connecting bolt located in the connecting horizontal rod 2 passes through the connecting horizontal rod 2 and is slidably connected to it. The end of the connecting bolt 5 extends out of the connecting sleeve rod 3 and is threadedly connected to a connecting nut 6. A mounting washer 7 is sandwiched between the connecting nut 6 and the outer wall of the connecting sleeve rod 3, and the mounting washer 7 is fitted onto the connecting bolt 5. A sealing rubber ring 12 is provided at the open end of the connecting sleeve. The inner ring wall of the sealing rubber ring 12 abuts against the peripheral wall of the connecting crossbar 2, reducing the possibility of external impurities entering the connecting sleeve.

[0029] Reference Figure 2 and Figure 3 The longitudinal section of the connecting crossbar 2 is smaller than the inner cross-sectional area of ​​the connecting sleeve 3, and the damping component 4 is disposed in the connecting sleeve 3. The damping component 4 includes a pressing block 41, a sliding rod 42, a sliding block 43, a damping spring 44, a connecting block 45, a pushing block 46, a damping block 47, and a damping rod 48. One pressing block 41 is connected to both the top and bottom surfaces of the connecting crossbar 2 within the connecting sleeve 3. The length direction of the pressing block 41 is parallel to the length direction of the connecting crossbar 2, and both ends of the pressing block 41 have a pressing inclined surface 411. Two sliding rods 42 are disposed along the length direction of the connecting sleeve 3, located above and below the connecting crossbar 2, respectively. Two sliding blocks 43 are disposed on each sliding rod 42, positioned between the pressing block 41 and the inner wall of the connecting sleeve 3. The two sliding blocks 43 on the same sliding rod 42 are located at the two ends of the corresponding pressing block 41 along its length direction. A damping spring 44 is fitted on each slide rod 42, and the two ends of the damping spring 44 are respectively connected to two corresponding sliding blocks 43. The sliding block 43 is provided with an abutting slope 431 corresponding to the extrusion slope 411 on the side near the extrusion block 41. Under the action of the damping spring 44, the abutting slope 431 of the sliding block 43 slides and fits against the extrusion slope 411 of the extrusion block 41.

[0030] Reference Figure 2 and Figure 3One connecting block 45 is connected to each of the two corresponding sliding blocks 43 on the side where they are close to each other. The end of the connecting block 45 away from the sliding block 43 is connected to the pushing block 46, which is located between the inner wall of the connecting sleeve rod 3 and the extrusion block 41. A first pushing inclined surface 461 is provided on the side of the pushing block 46 near the extrusion block 41, and the first pushing inclined surface 461 faces the corresponding sliding block 43. Two damping blocks 47 are provided in the connecting sleeve rod 3, and the two damping blocks 47 are respectively provided on opposite sides of the vertical direction of the connecting crossbar 2. A damping rod 48 is vertically provided on the side of each damping block 47 away from the extrusion block 41, and the end of the damping rod 48 away from the extrusion block 41 is connected to the inner wall of the connecting sleeve rod 3.

[0031] Reference Figure 2 and Figure 3 Two second propulsion ramps 471 are provided on the side of the shock-absorbing block 47 near the inner wall of the connecting sleeve rod 3. The angle of the second propulsion ramps 471 corresponds to the angle of the first propulsion ramps 461. The two second propulsion ramps 471 on the shock-absorbing block 47 correspond one-to-one with the first propulsion ramps 461 on the two propulsion blocks 46 and are slidably fitted together. A receiving groove 472 is provided on the side of the shock-absorbing block 47 near the extrusion block 41. An abutment block 9 is slidably disposed in the receiving groove 472. An abutment spring 8 is disposed in the receiving groove 472. One end of the abutment spring 8 is connected to the inner bottom wall of the receiving groove 472, and the other end is connected to the abutment block 9. In the natural state, the abutment block 9 is pressed against the extrusion block 41 under the action of the abutment spring 8. An end damping plate 10 is provided inside the connecting sleeve rod 3. One side of the end damping plate 10 is connected to the connecting vertical rod 1, and the other side abuts against the end of the connecting horizontal rod 2. A side damping plate 11 is connected to each of the two opposite inner walls of the connecting sleeve rod 3 in the horizontal direction. The side damping plate 11 abuts against the opposite sides of the connecting crossbar 2.

[0032] Reference Figure 1 and Figure 2 The connecting bolts 5 and connecting nuts 6 enable a detachable connection between the connecting crossbar 2 and the connecting sleeve 3. The end damping plate 10 provides shock absorption between the end of the connecting crossbar 2 and the connecting vertical bar 1, while the side damping plate 11 provides shock absorption between the horizontal sides of the connecting crossbar 2 and the connecting sleeve 3.

[0033] Reference Figure 2 and Figure 3When the connecting crossbar 2 wobbles vertically, the pressing block 41 located on one side of the connecting crossbar 2 moves accordingly. Simultaneously, the pressing inclined surfaces 411 at both ends of the pressing block 41 slide relative to the abutting inclined surfaces 431 of the two sliding blocks 43. Under the pressure of the pressing block 41, the two sliding blocks 43 move away from each other. The damping spring 44 stretches and accumulates elastic potential energy. Under the action of the damping spring 44, the sliding blocks 43 exert an opposite force on the pressing block 41, helping the connecting crossbar 2 return to its centered state more quickly. At the same time, the damping block 47 abuts against the pressing block 41 under the action of the damping rod 48, reducing the vibration level of the connecting crossbar 2.

[0034] Reference Figure 2 and Figure 3 As the sliding block 43 moves, the two propulsion blocks 46 move in opposite directions along with the two sliding blocks 43. The first propulsion ramp 461 and the second propulsion ramp 471 slide relative to each other. The damping block 47 moves towards the squeezing block 41 under the push of the propulsion block 46, further offsetting the vibration of the connecting crossbar 2. The abutting block 9 abuts against the connecting crossbar 2 under the action of the abutting spring 8, reducing the possibility of damage and deformation of the connecting crossbar 2 during the buffering process.

[0035] The implementation principle of a vibration damping structure for a building frame beam node in this embodiment is as follows: When the connecting crossbar 2 sways vertically, the compression block 41 moves accordingly. Two sliding blocks 43 move away from each other under the compression of the compression block 41. The sliding blocks 43 exert opposing forces on the compression block 41 under the action of the damping spring 44. Simultaneously, the damping block 47 abuts against the compression block 41 under the action of the damping rod 48, reducing the vibration of the connecting crossbar 2. As the sliding block 43 moves, the damping block 47 moves closer to the compression block 41 under the push of the propulsion block 46, further offsetting the vibration of the connecting crossbar 2.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
