Description

Technical Field

[0001] This invention relates to the field of earthquake-resistant building structures, and specifically to a unidirectional earthquake-resistant structure. Background Technology

[0002] In seismic-resistant shear wall structures, several seismic-resistant structures are usually set in the width direction of the bottom of the shear wall, which reduces the seismic resistance of the shear wall. In ordinary seismic-resistant structures, the shear wall will fully participate in seismic resistance when it is subjected to any vibration. When it cannot withstand the vibration force, the seismic resistance of the shear wall itself will be relied upon. Ordinary seismic-resistant structures do not utilize the seismic resistance of the shear wall at the beginning of an earthquake, causing the ordinary seismic-resistant structures to bear excessive force, which can easily lead to the failure of the energy dissipation units in the ordinary seismic-resistant structures. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a unidirectional seismic-resistant structure. This solves the problem that in existing ordinary seismic-resistant structures, the shear wall fully participates in seismic resistance when subjected to any vibration. When the shear wall can no longer withstand the vibration, the seismic resistance is then provided by the shear wall itself. Ordinary seismic-resistant structures do not utilize the seismic resistance of the shear wall at the beginning of an earthquake, causing the ordinary seismic-resistant structure to bear excessive force and easily leading to the failure of energy dissipation units in the ordinary seismic-resistant structure.

[0004] The technical solution to achieve the above objectives is:

[0005] This invention provides a unidirectional seismic-resistant structure, comprising:

[0006] Connect the base plate;

[0007] A variable cross-section sleeve is erected on the connecting base plate, wherein the inner diameter of the middle part of the variable cross-section sleeve is larger than the inner diameter of both ends;

[0008] A damping ball is disposed inside the variable cross-section sleeve. The diameter of the damping ball is adapted to the inner diameter of the middle part of the variable cross-section sleeve, and the diameter of the damping ball is larger than the inner diameter of both ends of the variable cross-section sleeve.

[0009] A connecting rod is inserted into the variable cross-section sleeve and connected to the damping ball. The connecting rod is vertically arranged and its top extends out of the variable cross-section sleeve to form a connecting end.

[0010] A connecting top plate that is fixedly connected to the connecting end.

[0011] A further improvement of the unidirectional seismic-resistant structure of the present invention is that the middle part of the variable cross-section sleeve is a vertical section, the diameter of the damping ball is smaller than the inner diameter of the vertical section of the variable cross-section sleeve, and the two ends of the variable cross-section sleeve are wedge-shaped sections, the diameter of the damping ball is larger than the inner diameter of the wedge-shaped section.

[0012] A further improvement of the unidirectional seismic-resistant structure of the present invention is that the wedge-shaped sections at both ends of the variable cross-section sleeve are provided with an upper strip-shaped through hole and a lower strip-shaped through hole arranged vertically;

[0013] The connecting rod is connected to an upper spoke located above the damping ball and a lower spoke located below the damping ball;

[0014] The upper spokes have a portion extending from the upper strip-shaped through hole, and the lower spokes have a portion extending from the lower strip-shaped through hole.

[0015] A further improvement of the unidirectional seismic-resistant structure of the present invention is that it also includes a lower support plate sleeved on the lower part of the variable cross-section sleeve and supported on the connecting base plate. The lower support plate is located below the lower spokes and above the bottom of the lower strip-shaped through hole.

[0016] The lower spokes are multiple, and the ends of the multiple lower spokes are connected together by a lower limiting ring.

[0017] A further improvement of the unidirectional seismic structure of the present invention is that it also includes an upper support plate sleeved on the upper part of the variable cross-section sleeve and supported on the connecting base plate. The upper support plate is located above the upper spokes and also below the top of the upper strip-shaped through hole.

[0018] The upper spokes are multiple, and the ends of the multiple upper spokes are connected together by an upper limiting ring.

[0019] A further improvement of the unidirectional seismic-resistant structure of the present invention is that a prestressed cable is connected between the upper support plate and the lower support plate.

[0020] A further improvement of the unidirectional seismic-resistant structure of the present invention is that the upper support rod is supported on the connecting base plate, passes through the lower support plate, and supports the upper support plate.

[0021] A further improvement of the unidirectional seismic-resistant structure of the present invention is that there are four upper support rods, which are respectively set at the four corners of the upper support plate.

[0022] A further improvement of the unidirectional seismic-resistant structure of the present invention is that the unidirectional seismic-resistant structure can be arranged symmetrically at the same time.

[0023] A further improvement of the unidirectional seismic-resistant structure of the present invention is that the variable cross-section sleeve is made of alloy steel.

[0024] The beneficial effects of this invention are: when a building resists vibration through this unidirectional seismic-resistant structure, it first resists vibration through the seismic resistance of the shear wall itself, then resists vibration through the movement of the damping ball in the variable cross-section sleeve and the resistance of the variable cross-section sleeve to the damping ball, and finally resists vibration through the upper and lower spoke limiting rings supporting the upper and lower support plates. Through the multi-stage seismic-resistant structure, the seismic resistance is fully utilized, the life of the energy dissipation unit is extended, and the building is better able to resist vibrations.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] See Figure 1 and Figure 2 As shown, the present invention provides a unidirectional seismic-resistant structure, including: a connecting top plate 1, a connecting bottom plate 2, a damping ball 5, a variable cross-section sleeve 8, and a connecting rod 9.

[0035] The variable cross-section sleeve 8 is erected on the connecting base plate 2, and the inner diameter of the middle part of the variable cross-section sleeve 8 is larger than the inner diameter of the two ends.

[0036] The damping ball 5 is disposed inside the variable cross-section sleeve 8. The damping ball 5 is connected to the connecting top plate 1 through the connecting rod. The diameter of the damping ball 5 is adapted to the inner diameter of the middle part of the variable cross-section sleeve 8. The diameter of the damping ball 5 is larger than the inner diameter of both ends of the variable cross-section sleeve 8. The damping ball 5 is locked in the middle part of the variable cross-section sleeve 8. The vertical movement of the damping ball 5 is restricted by the inner diameter of the variable cross-section sleeve 8.

[0037] The connecting rod 9 is inserted into the variable cross-section sleeve 8 and connected to the damping ball 5. The connecting rod 9 is set vertically and its top extends out of the variable cross-section sleeve 8 to form a connecting end. The connecting top plate 1 is fixedly connected to the connecting end.

[0038] This structure can be applied to the seismic resistance of shear walls. Connectors are pre-embedded in the shear walls and floor slabs. The unidirectional seismic-resistant structure is erected on the floor slab at the bottom of the shear wall. The top slab 1 and the shear wall are connected by the connectors, and the bottom slab 2 and the floor slab are fixed. The top slab 1 supports the shear wall and bears the vibrations experienced by the shear wall.

[0039] like Figure 2 As shown, further, in the unidirectional seismic-resistant structure of the present invention, the middle part of the variable cross-section sleeve 8 is a vertical section, the diameter of the damping ball 5 is smaller than the inner diameter of the vertical section, and the damping ball 5 is locked in the vertical section. The two ends of the variable cross-section sleeve 8 are wedge-shaped sections, and the diameter of the damping ball 5 is larger than the inner diameter of the wedge-shaped section. Since the inner diameter of the vertical section of the variable cross-section sleeve 8 is larger than the inner diameter of the two wedge-shaped sections, and the damping ball 5 is locked in the vertical section of the variable cross-section sleeve 8, the movement of the damping ball 5 towards the two wedge-shaped sections will be subject to a certain resistance. When the unidirectional seismic-resistant structure of the present invention is subjected to vibration, the force will act on the connecting top plate, and then be transmitted to the damping ball through the connecting rod. The damping ball will move under the action of this force. When the damping ball moves to the wedge-shaped section, the wedge-shaped section applies resistance to the movement of the damping ball. This resistance can offset part of the force acting on the damping ball, realizing energy dissipation, thereby consuming the vibration received by components such as shear walls, and enabling the shear walls to recover to a stable state more quickly.

[0040] Combination Figure 5 and Figure 7 As shown, preferably, the upper wedge-shaped section of the variable cross-section sleeve 8 in the unidirectional seismic structure of the present invention has an upper strip-shaped through hole. The upper strip-shaped through hole is opened along the direction of the connecting rod 9. In a preferred embodiment, when the structure is vertically arranged, the upper strip-shaped through hole is vertically arranged. An upper spoke is connected to the connecting rod 9 above the damping ball 5. The upper spoke is arranged corresponding to the upper strip-shaped through hole. Part of the upper spoke extends out from the upper strip-shaped through hole. As the connecting rod 9 moves vertically, the upper spoke also moves along the upper strip-shaped through hole. The upper spoke can abut against the top of the upper strip-shaped through hole as the damping ball 5 moves. There are multiple upper spokes, and the ends of multiple upper spokes are connected together by an upper limiting ring 6.

[0041] When the upper spoke moves within the upper strip-shaped through hole, the upper spoke through hole has a guiding function. The upper strip-shaped through hole provides a guiding force to the upper spoke, so that the upper spoke can only move in the direction of the upper strip-shaped through hole, thereby realizing the transmission of force.

[0042] When the connecting top plate 1 is under tension, the connecting rod 9 is forced to move the damping ball 5 and the upper spokes upward to the top of the upper strip-shaped through hole. The upper spokes are restricted from moving upward due to the force exerted by the top of the upper strip-shaped through hole, and can no longer move upward. The upper spokes transmit the force to the connecting top plate 1 through the connecting rod 9, thereby pulling the connecting top plate 1 downward and reducing the vibration of the shear wall.

[0043] Furthermore, in the unidirectional seismic structure of the present invention, the lower wedge-shaped section of the variable cross-section sleeve 8 is provided with a lower strip-shaped through hole. The lower strip-shaped through hole is opened along the direction of the connecting rod 9. In a preferred embodiment, when the structure is vertically arranged, the lower strip-shaped through hole is vertically arranged. The connecting rod 9 is connected to a lower spoke located below the damping ball 5. The lower spoke is arranged corresponding to the lower strip-shaped through hole. Part of the lower spoke extends out from the lower strip-shaped through hole. As the connecting rod 9 moves vertically, the lower spoke also moves along the lower strip-shaped through hole. The lower spoke can abut against the bottom of the lower strip-shaped through hole as the damping ball 5 moves. There are multiple lower spokes, and the ends of multiple lower spokes are connected together by a lower limiting ring 7.

[0044] When the lower spokes move within the lower strip-shaped through hole, the lower spoke through hole has a guiding function. The lower strip-shaped through hole provides a guiding force to the lower spokes, so that the lower spokes can only move in the direction of the lower strip-shaped through hole, thereby realizing the transmission of force.

[0045] When the connecting top plate 1 is compressed, the connecting rod 9 is forced to move the damping ball 5 and the lower spokes downward to the bottom of the lower strip-shaped through hole. The lower spokes are restricted from moving downward due to the force exerted by the bottom of the lower strip-shaped through hole, and can no longer move downward. The lower spokes transmit the force to the connecting top plate 1 through the connecting rod 9, thereby supporting the connecting top plate 1 upward and reducing the vibration of the shear wall.

[0046] Combination Figure 1 and Figure 2As shown, in the unidirectional seismic-resistant structure of the present invention, the upper support plate 3 and the lower support plate 4 are respectively sleeved on the upper and lower parts of the variable cross-section sleeve 8 to reinforce the variable cross-section sleeve 8, increase its load-bearing capacity, and improve the overall durability of the structure. The variable cross-section sleeve 8 is supported on the connecting base plate 2. One end of the connecting rod 9 is connected to the connecting top plate 1, and the other end is connected to the damping ball 5. The damping ball 5 is suspended between the upper support plate 3 and the lower support plate 4. The damping ball 5 can move along the direction of the connecting rod 9. The damping ball 5 moves and is supported by the upper limiting ring 6 and the lower limiting ring 7 against the upper support plate 3 and the lower support plate 4 respectively, thereby achieving the abutment and restriction between the upper limiting ring 6 and the lower limiting ring 7 and the upper support plate 3 and the lower support plate 4. The upper support plate 3 and the lower support plate 4 limit the range of movement of the damping ball 5, giving the damping ball 5 resistance to continue moving. The damping ball 5 transmits this resistance to the connecting top plate 1 through the connecting rod 9, thereby acting on the shear wall and realizing the vibration reduction function of the shear wall.

[0047] A prestressed cable 10 is installed between the upper support plate 3 and the lower support plate 4. The prestressed cable 10 connects the upper support plate 3 and the lower support plate 4 together, limiting the distance between the upper support plate 3 and the lower support plate 4. Thus, when the upper limiting ring 6 and the lower limiting ring 7 abut against the upper support plate 3 or the lower support plate 4, sufficient force is provided to the shear wall to resist vibration. Under the support of the prestressed cable 10, the upper support plate 3 and the lower support plate 4 maintain force balance. The entire structure maintains overall force balance under non-earthquake conditions.

[0048] Preferably, regardless of whether the structure is under tension or compression, the prestressed cable 10 can be further elongated or compressed to form a restoring force, and the prestressed cable 10 can provide appropriate force to help the structure achieve self-resetting.

[0049] like Figure 2 As shown, further, in the unidirectional seismic structure of the present invention, the connecting rod 9 is welded to the connecting top plate 1, the upper limiting ring 6 and the lower limiting ring 7 are welded and fixed to the connecting rod 9, the variable cross-section sleeve 8 is welded to the connecting bottom plate 2, the upper support plate 3 is sleeved and welded to the upper part of the variable cross-section sleeve 8, the lower support plate 4 is sleeved and welded to the lower part of the variable cross-section sleeve 8, and the prestressed cable 10 is tensioned between the upper support plate 3 and the lower support plate 4.

[0050] Preferably, the variable cross-section sleeve 8 is made of alloy steel, which has both good elasticity and strength, so that the damping ball 5 can provide sufficient resistance when it is squeezed with the wedge section without causing damage to itself, thus extending the service life of the component. The damping ball 5 can be made of lead or mild steel.

[0051] like Figure 2As shown, the upper support plate 3 is further supported on the connecting base plate 2 by the upper support rod 11, and the lower support plate 4 is supported on the connecting base plate 2 by the lower support rod 12. Setting independent upper support rod 11 and lower support rod 12 is beneficial to improve the strength of the support. Compared with a single support rod supporting both the upper support plate 3 and the lower support plate 4 at the same time, it has better support performance.

[0052] There are four upper support rods 11 and four lower support rods 12, which are respectively located at the four corners of the upper support plate 3 and the lower support plate 4 to provide even support.

[0053] Combination Figure 4 As shown, in order to better protect the shear wall, this unidirectional seismic-resistant structure is set on both sides of the shear wall. This structure can be subjected to both compression and tension, and can provide the shear wall with restoring force to restore it to the equilibrium position under both compression and tension.

[0054] Combination Figure 1 , Figure 2 and Figure 4 As shown, when the shear wall is vibrating and swaying, the connecting top plate 1 is subjected to the pressure or tension of the shear wall. Through the transmission of the connecting rod 9, it is guided by the upper strip-shaped through hole and the lower strip-shaped through hole on the upper and lower spokes respectively, so that the damping ball 5 moves vertically in the variable cross-section sleeve 8.

[0055] Under minor earthquakes, the shear wall structure deforms less, causing the damping ball 5 to move within the vertical section under a smaller force. The variable cross-section sleeve 8 and the prestressed cable 10 do not participate in earthquake resistance, thus avoiding the introduction of additional seismic energy into the structure due to increased stiffness. At this time, the earthquake is resisted by the shear wall's own lateral resistance capacity.

[0056] Under moderate earthquakes, the deformation of the shear wall structure increases, causing the damping ball 5 to be driven by a greater force, which in turn causes the damping ball 5 to move within the wedge section. The damping ball 5 undergoes compression deformation and dissipates energy. The wedge section participates in earthquake resistance, while the prestressed cable 10 does not participate in earthquake resistance. Through the additional resistance provided by the wedge section, the seismic energy is dissipated, and the seismic response is reduced.

[0057] Under a major earthquake, when the shear wall structure experiences significant swaying, the structural deformation is substantial. When the structure is under compression, the lower limiting ring 7 will press against the lower support plate 4. When the structure is under tension, the upper limiting ring 6 will press against the upper support plate 3, triggering the prestressed cables 10 to participate in seismic resistance and provide restoring force. If one side of the two corner walls is under tension and the other under compression, both sides can provide restoring force, achieving double the self-resetting capacity compared to traditional techniques. Simultaneously, the damping sphere 5 will continue to deform under compression, further dissipating energy and providing additional damping to the structure, thus dissipating seismic energy. The wedge-shaped segment and the prestressed cables 10 work together to resist seismic forces, effectively reducing the structural response under a major earthquake and achieving self-resetting.

[0058] This structure features an integrated modular design. The prestressed cables 10 do not need to penetrate the wall or be tensioned on-site, saving on the number of prestressed cables 10. Construction and replacement are simple, reducing construction difficulty and shortening the construction period.

[0059] This structure can adapt to different earthquake stages, match the optimal seismic resistance strategy, and improve the seismic resistance effect.

[0060] When the wall sways during an earthquake, it has a strong self-resetting ability, good stability, wide applicability, and built-in limit function, avoiding the hidden dangers caused by sudden structural failure.

[0061] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
