Abstract
Description
Technical Field
[0001] This utility model relates to the field of seismic bracing technology, specifically to an angle-adaptive seismic bracing. Background Technology
[0002] During the construction process, various pipelines are often laid, which is one of the key links in the entire project's infrastructure construction. The pipeline system is mainly used to transport fluid media such as domestic water, fire-fighting water, and natural gas to ensure that the building has normal living and safety protection functions after completion. Among them, tap water pipelines are used to meet the daily water needs of residents; fire-fighting water pipes are an important part of the building's fire protection system, responsible for providing sufficient water in the event of a fire; and natural gas pipelines are responsible for providing users with clean and efficient fuel energy.
[0003] However, in actual use, if these pipes are directly fixed to the wall surface during construction without corresponding seismic support measures, they are prone to loosening, falling off, or even falling completely during sudden natural disasters such as earthquakes due to the different vibration frequencies of the building wall and the pipes. Once the pipes fall, it will not only cause the pipe body to rupture and the transported medium to leak, but may also injure people and damage the internal facilities of the building. In view of this, we propose an angle-adaptive seismic support. Utility Model Content
[0004] The purpose of this invention is to provide an angle-adaptive seismic bracing system to solve the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an angle-adaptive seismic brace, comprising an upper clamp, a lower clamp fixedly connected to the bottom of the upper clamp by bolts, and a shock-absorbing component provided on the bottom end face of the lower clamp, the shock-absorbing component comprising:
[0006] A fixed frame, wherein a connecting frame is fixedly connected to the bottom of the fixed frame, and a sliding groove is provided on the inner bottom surface of the connecting frame;
[0007] The guide rail has a roller rotatably connected to its bottom end face and a groove 2 formed on its top end face.
[0008] The mounting rod, the bottom of which is movably connected to the pendulum damper via a rotatably connected connecting ball;
[0009] A vertical plate, the side wall of which is hinged with a threaded sleeve, the threaded sleeve being threadedly connected to a connecting rod.
[0010] Preferably, the first slide groove is movably connected to the first roller, allowing the guide rail to move vertically along the first slide groove. The outer wall of the lower clamp is rotatably connected to the second roller, which is movably connected to the second slide groove, allowing the lower clamp to move laterally along the second slide groove.
[0011] Preferably, the vertical plate is fixedly connected to the inner wall of the connecting frame, and the two ends of the connecting rod are threadedly connected to threaded sleeves. One set of threaded sleeves is hinged to the vertical plate, and the other set of threaded sleeves is hinged to the outer wall of the lower clamp.
[0012] Preferably, the connecting rod has a small diameter section in the middle, the diameter of which is smaller than the diameter of other parts of the connecting rod. When encountering seismic shear waves, the vibration frequency of the pipeline and the building is different, which causes the lower clamp and the connecting frame to misalign, causing the connecting rod to break at the small diameter section, and the connecting rod to remove the limiting effect on the lower clamp.
[0013] Preferably, the mounting rod is fixedly connected to the bottom of the lower clamp, and the pendulum damper is located directly below the lower clamp.
[0014] Preferably, the first slide groove and the second slide groove are set at a 90-degree angle, and the number of guide rails is set to two sets, with the two sets of guide rails located above the inner bottom surface of the connecting frame.
[0015] Preferably, a limit damper is fixedly connected to the inner wall of the connecting frame, the limit damper is movably connected to the side wall of the guide rail, mounting brackets are fixedly connected to both ends of the guide rail, a limit damper is fixedly connected to the side wall of the mounting bracket, and the limit damper is movably connected to the outer wall of the lower clamp.
[0016] Compared with the prior art, this utility model provides an angle-adaptive seismic bracing system, which has the following beneficial effects:
[0017] 1. This angle-adaptive seismic support, through its damping components, allows the pendulum damper to swing in the opposite direction of the pipeline's inertial motion when the pipeline oscillates due to horizontal vibration during an earthquake. This creates a phase difference with the pipeline's vibration and cancels out some of the energy, thereby reducing the actual movement amplitude of the main structure, reducing swaying impact, lowering the stress on the pipeline body and interfaces, and improving the pipeline's seismic toughness and stability. In the absence of an earthquake, it provides positioning and limiting functions for the lower clamp to prevent displacement and maintain system stability. During an earthquake, if the vibration causes relative misalignment between the pipeline and the building, the connecting rod will bear lateral or axial shear force. Once this force exceeds the strength limit of the small diameter section, the connecting rod will break preferentially at this point, thereby automatically releasing the constraint on the lower clamp and allowing the device to become a flexible response state, thus avoiding more serious structural damage.
[0018] 2. The angle-adaptive seismic bracing, through the setting of limit damper one and limit damper two, provides a non-rigid blocking mechanism. Even if the guide rail and lower clamp hit the limit end, there will be no hard collision, reducing impact damage. It allows the pipeline and clamp to respond freely to seismic displacement within a certain range, but it also flexibly limits them in time before they approach the structural boundary.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: an angle-adaptive seismic brace, including an upper clamp 1, a lower clamp 2 fixedly connected to the bottom of the upper clamp 1 by bolts, and a shock-absorbing component 3 provided on the bottom end face of the lower clamp 2. The shock-absorbing component 3 includes a fixing frame 301, a connecting frame 302, a first slide groove 303, a guide rail 304, a first roller 305, a second slide groove 306, a second roller 307, a mounting rod 308, a pendulum damper 309, a vertical plate 310, a threaded sleeve 311, and a connecting rod 312.
[0026] In one embodiment of this utility model, a connecting frame 302 is fixedly connected to the bottom of the fixed frame 301. A first groove 303 is provided on the inner bottom surface of the connecting frame 302. A first roller 305 is rotatably connected to the bottom end face of the guide rail 304. The first groove 303 and the first roller 305 are movably connected, allowing the guide rail 304 to move vertically along the first groove 303. A second groove 306 is provided on the top end face of the guide rail 304. A second roller 307 is rotatably connected to the outer wall of the lower clamp 2. The second roller 307 and the second groove 306 are movably connected, allowing the lower clamp 2 to move laterally along the second groove 306. The angle between the first groove 303 and the second groove 306 is set at ninety degrees. Two sets of guide rails 304 are provided, and the two sets of guide rails 304 are located above the inner bottom surface of the connecting frame 302.
[0027] The bottom of the mounting rod 308 is movably connected to the pendulum damper 309 via a rotating connecting ball. The mounting rod 308 is fixedly connected to the bottom of the lower clamp 2. The pendulum damper 309 is located directly below the lower clamp 2. The side wall of the vertical plate 310 is hinged with a threaded sleeve 311, which is threadedly connected to the connecting rod 312. The vertical plate 310 is fixedly connected to the inner wall of the connecting frame 302. The two ends of the connecting rod 312 are threadedly connected with threaded sleeves 311. One set of threaded sleeves 311 is hinged to the vertical plate 310, and the other set of threaded sleeves 311 is hinged to the outer wall of the lower clamp 2. The connecting rod 312 has a small diameter section in the middle, and the diameter of the small diameter section is smaller than the diameter of other parts of the connecting rod 312. When encountering seismic shear waves, the vibration frequency of the pipe and the building is different, which causes the lower clamp 2 and the connecting frame 302 to misalign, causing the connecting rod 312 to break at the small diameter section. The connecting rod 312 then stops limiting the lower clamp 2.
[0028] The pipe is fixed between the upper clamp 1 and the lower clamp 2. The pipe is then secured by the upper clamp 1 and the lower clamp 2. The fixing bracket 301 is then fixed to the ceiling of the building. When an earthquake occurs, the transverse waves of the earthquake cause the building to sway left and right or back and forth. Since the vibration frequencies of the building and the pipe are different, the guide rail 304 can move along the first slide 303 in the Y-axis direction, and the lower clamp 2 can move along the second slide 306 in the X-axis direction. This allows the shock absorption component 3 to absorb the relative displacement in these directions without tearing the pipe, avoiding breakage or excessive displacement caused by the forced rigid connection. The propagation direction of the transverse wave in an actual earthquake is complex. It may not be a pure X or pure Y direction, but rather an oscillation at any angle. The first slide 303 and the second slide 306 provide free sliding capability in a two-dimensional plane, thereby adapting to the impact of transverse waves at any angle and improving the overall system's resilience.
[0029] The bottom of the lower clamp 2 is connected to the pendulum damper 309 via a connecting ball. When the pipeline is subjected to horizontal vibration and swings during an earthquake, the pendulum damper 309 swings in the opposite direction of inertia, creating a phase difference with the vibration of the pipeline and canceling out some of the energy. This reduces the actual movement amplitude of the main structure, reduces the swaying impact, lowers the stress on the pipeline body and interface, and improves the seismic toughness and stability of the pipeline.
[0030] The connecting rod 312 supports the lower clamp 2 when there is no earthquake. The connecting rod 312 has a small diameter section in the middle, the diameter of which is smaller than the diameter of other parts of the connecting rod 312. When an earthquake shear wave is encountered, the vibration frequency of the pipeline and the building is different, which causes the lower clamp 2 to misalign with the connecting frame 302, causing the connecting rod 312 to break at the small diameter section. The connecting rod 312 then releases its restraint on the lower clamp 2. Normally, the connecting rod 312 is a rigid support component, providing positioning and restraint functions for the lower clamp 2 in the absence of an earthquake, preventing its displacement and maintaining system stability. When an earthquake occurs, if the vibration causes relative misalignment between the pipeline and the building, the connecting rod 312 will bear lateral or axial shear force. Once this force exceeds the strength limit of the small diameter section, the connecting rod 312 will break preferentially at this point, thereby automatically releasing the restraint on the lower clamp 2, allowing the device to become a flexible response state, thus avoiding more serious structural damage.
[0031] In addition, a limit damper 4 is fixedly connected to the inner wall of the connecting frame 302. The limit damper 4 is movably connected to the side wall of the guide rail 304. Mounting brackets 5 are fixedly connected to both ends of the guide rail 304. Limit dampers 6 are fixedly connected to the side wall of the mounting brackets 5. Limit dampers 6 are movably connected to the outer wall of the lower clamp 2. Limit dampers 4 and 6 limit the sliding range of the guide rail 304 and the lower clamp 2. Limit dampers 4 and 6 provide a non-rigid blocking mechanism. Even if the guide rail 304 and the lower clamp 2 hit the limiting end, there will be no hard impact, reducing impact damage. The pipe and clamp are allowed to respond freely to seismic displacement within a certain range, but they are flexibly limited in time before they approach the structural boundary to prevent them from rushing out of the slide groove 303 or slide groove 306, detaching from the system or damaging the structure.
[0032] In this invention, during use, the pipe is fixed between the upper clamp 1 and the lower clamp 2. The pipe is secured by the upper clamp 1 and the lower clamp 2. Then, the fixing bracket 301 is fixed to the ceiling of the building. The guide rail 304 can move along the first slide groove 303 in the Y-axis direction, and the lower clamp 2 can move along the second slide groove 306 in the X-axis direction. This allows the shock-absorbing component 3 to absorb relative displacement in these directions without tearing the pipe. The bottom of the lower clamp 2 is connected to the pendulum damper 309 via a connecting ball. When the pipe is subjected to horizontal vibration during an earthquake and swings, the pendulum damper 309 swings with inertia in the opposite direction, creating a phase with the vibration of the pipe. The difference and offset of some energy reduce the actual movement amplitude of the main structure, reduce swaying impact, reduce the stress on the pipe body and interface, and improve the seismic toughness and stability of the pipe. When encountering seismic shear waves, the vibration frequency of the pipe and the building is different, which causes the lower clamp 2 and the connecting frame 302 to misalign, causing the connecting rod 312 to break at the small diameter part. The connecting rod 312 cancels the constraint on the lower clamp 2. The connecting rod 312 is normally a rigid support member, providing positioning and limiting functions for the lower clamp 2 in the absence of earthquake. When an earthquake occurs, the connecting rod 312 will break first at this point, thereby automatically releasing the constraint on the lower clamp 2, making the device a flexible response state, and avoiding more serious structural damage.
[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
