Description

Technical Field

[0001] The patent of this invention relates to the field of damper technology, specifically to a high-speed, large-displacement viscous damping wall. Background Art

[0002] Viscous damping walls are a new type of seismic energy dissipation component for building structures. They were first proposed by Japanese scholar M. Miyazaki et al. at the First East Asian Structural Engineering Conference in 1986. Existing viscous damping walls consist of a shear steel box fixed to the bottom beam of the lower floor and an inner shear plate fixed to the bottom beam of the upper floor and inserted into the shear steel box. The inner shear plate is maintained at an appropriate distance from the shear steel box panel. An upper fluid reservoir is located above the shear steel box. Both the shear steel box and the upper fluid reservoir are filled with a highly viscous viscous damping fluid. When relative displacement or velocity occurs between floors, the inner shear plate slides in the viscous damping fluid within the shear steel box, generating shear force against the viscous damping fluid between the inner shear plate and the shear steel box, dissipating seismic energy and thereby reducing the structure's seismic response.

[0003] Because the inner shear plate has a certain thickness, its left-right movement inevitably causes changes in the volume of the left and right sides of the shear steel box. Due to the incompressibility of the viscous damping fluid, the viscous damping fluid on the side with reduced volume will flow upward and be squeezed out from the top, while the viscous damping fluid on the side with increased volume will flow downward and be drawn into the shear steel box. Therefore, conventional viscous damping walls employ an upper liquid reservoir above the shear steel box to accommodate and compensate for this volume change. Specifically, as the inner shear plate moves to one side, the volume of the shear steel box decreases on that side, causing the viscous damping fluid to flow upward, forcing the liquid level in the upper liquid reservoir on that side to rise. Meanwhile, on the other side, the volume of the shear steel box increases, causing the liquid level in the upper liquid reservoir to drop.

[0004] In order to achieve higher energy consumption efficiency, the viscous damping fluid commonly used in viscous damping walls has extremely high viscosity. However, high-viscosity liquids have disadvantages such as large flow resistance, large surface tension, and poor fluidity.

[0005] In existing viscous damping walls, the upper liquid reservoir for volume compensation is located above the shear steel box. The height of the inner shear plate is typically 1 to 2 meters, or even higher. When the volume of one side of the shear steel box increases and the viscous damping fluid needs to be replenished, the viscous damping fluid must flow downward through the narrow channel between the two panels of the steel box, a distance of 1 to 2 meters, or even longer. Due to the poor fluidity of the viscous damping fluid and the difference in distance between the upper and lower parts of the shear steel box and the upper liquid reservoir, the upper part is easier to refill with fluid, while the lower part is more difficult to refill, which easily forms a vacuum cavity in the lower part. This is particularly true when the inner shear plate operates at high speeds and large displacements. Untimely refilling can cause the vacuum cavity to expand to near the top liquid level. When atmospheric pressure breaks through the liquid layer at the top of the vacuum cavity, air enters the shear steel box, causing the viscous damping fluid to be lost between the inner shear plate and the shear steel box panel, resulting in a rapid decay and failure of the damping force.

[0006] The inventors conducted a survey of nearly 1,000 projects using inter-story seismic isolation technology and found that, depending on the building's floor height, the maximum inter-story velocity at the design fortification intensity ranged from approximately 150 mm / s to 350 mm / s, with 90% of the design allowable displacement falling within the range of ±30 to ±45 mm. However, due to the aforementioned issues, existing viscous damping walls limit their maximum operating speed to below 150 mm / s and their design allowable displacement to within ±30 mm, significantly limiting their applicability.

[0007] It can be seen from this that it is necessary to invent a high-speed and large-displacement viscous damping wall that can meet most application requirements. Summary of the Invention

[0008] In response to the deficiencies in the prior art, the present invention provides a high-speed, large-displacement viscous damping wall. The wall rapidly absorbs and compensates for the volume changes of the left and right cavities caused by the movement of the inner shear plate through the expansion and contraction deformation of the volume compensation bladder arranged in the side liquid storage cavity, thereby eliminating the problems of vacuum cavity and air inhalation caused by untimely compensation. The wall is particularly suitable for situations where the inner shear plate has a high speed and large displacement, and can effectively improve the scope of application of the viscous damping wall to meet the needs of most engineering applications.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A high-speed, large-displacement viscous damping wall comprises an upper flange plate and a lower flange plate fixedly connected to the bottom beams of the upper and lower floors, an inner shear plate connected to the upper flange plate, a shear steel box and a side liquid storage chamber connected to the lower flange plate, the side liquid storage chamber being arranged on the side wall of the shear steel box, an upper liquid storage chamber being arranged on the top of the shear steel box, the side liquid storage chamber being connected to the shear steel box through a slot arranged on the side plate of the shear steel box, when the volume in the side shear steel box increases, the viscous damping liquid in the side liquid storage chamber can be quickly replenished into the shear steel box laterally, and when the volume in the side shear steel box decreases, the viscous damping liquid in the shear steel box can be quickly filled into the side liquid storage chamber laterally, a volume compensation bladder is arranged in the side liquid storage chamber, which utilizes the compressibility of air and the elastic deformation of the bladder to absorb and compensate for the volume change caused by the movement of the inner shear plate, the side liquid storage chamber and the volume compensation bladder greatly shorten the filling and compensation flow distance of the viscous damping liquid, make the filling and compensation more immediate and rapid, and minimize the formation of vacuum cavities. The side liquid storage chamber effectively increases the flow cross-sectional area of ​​the viscous damping fluid in the vertical direction, reduces the resistance of the viscous damping fluid in the vertical direction, makes the filling compensation more immediate and rapid, and can minimize the formation of vacuum-like cavities. The side liquid storage chamber effectively increases the transverse section inertia moment of the viscous damping wall, improves the stiffness of the shear steel box, and thus effectively improves the initial stiffness of the viscous damping wall. The inner shear plate is inserted into the shear steel box and keeps a distance from the front panel and the rear panel of the shear steel box. The shear steel box, the upper liquid storage chamber and the side liquid storage chamber are filled with viscous damping fluid. When the earthquake causes the upper and lower floors to produce relative displacement, the inner shear plate is driven to move left and right in the shear steel box and shears the viscous damping fluid placed between the inner shear plate and the shear steel box, thereby generating damping force and realizing energy consumption. The upper liquid storage chamber and the volume compensation bladder placed in the side liquid storage chamber provide compensation for the volume changes of the left and right cavities caused by the movement of the inner shear plate.

[0011] Furthermore, the volume compensation bladder in the side liquid storage cavity can quickly absorb and compensate for the volume changes of the left and right cavities caused by the movement of the inner shear plate through expansion and contraction deformation, changing the vertical long-distance compensation to the horizontal short-distance rapid compensation, eliminating the vacuum cavity and air inhalation problems caused by untimely compensation. It is particularly suitable for the conditions of high speed and large displacement of the inner shear plate, and can effectively improve the application range of the viscous damping wall to meet the needs of most engineering applications.

[0012] Furthermore, the side liquid storage chamber is arranged on one side or both sides of the shear steel box.

[0013] Furthermore, the side liquid storage chamber is formed by welding U-shaped bent plates, channel steels or rectangular tubes to shear steel box side plates and lower flange plates and is sealed from the outside world, thereby preventing leakage of viscous damping fluid.

[0014] Furthermore, the volume compensation bladder is a hollow structure, and the lower opening of the volume compensation bladder is closed, which has the function of preventing the viscous damping fluid from entering its inner cavity.

[0015] Furthermore, the cross-sectional shape of the volume compensation bladder can be circular, hollow rectangular or hollow irregular, and its recovery elasticity after deformation and atmospheric pressure can be used to push the viscous damping fluid to quickly fill the volume cavity, thereby minimizing the formation of a vacuum cavity.

[0016] Furthermore, the slots on the side panels of the shear steel box can be round holes, rectangular holes, rectangular slots, waist-shaped slots, special-shaped holes, special-shaped slots, and the like.

[0017] Compared with the prior art, the present invention has at least one of the following beneficial effects: the present invention provides a high-speed, large-displacement viscous damping wall, which compensates for the volume changes of the left and right chambers caused by the movement of the inner shear plate through the upper liquid storage chamber and the volume compensation bladder placed in the side liquid storage chamber. In particular, the volume compensation bladder in the side liquid storage chamber can quickly absorb and compensate for the volume changes of the left and right chambers caused by the movement of the inner shear plate through expansion and contraction deformation, changing the vertical long-distance compensation to the horizontal short-distance rapid compensation, eliminating the vacuum cavity and air inhalation problems caused by untimely compensation, and is particularly suitable for high-speed and large-displacement conditions of the inner shear plate. It can effectively improve the application range of the viscous damping wall and meet the needs of most engineering applications. BRIEF DESCRIPTION OF THE DRAWINGS

The upper liquid storage chamber 3 and the volume compensation bladder 7 placed in the side liquid storage chamber 4 provide compensation for the volume changes of the left and right chambers caused by the movement of the inner shear plate 2.

[0045] The volume compensation bladder 7 in the side liquid storage chamber 4 can quickly absorb and compensate for the volume changes of the left and right chambers caused by the movement of the inner shear plate 2 through expansion and contraction deformation, changing the vertical long-distance compensation to the horizontal short-distance rapid compensation, eliminating the vacuum cavity and air inhalation problems caused by untimely compensation, which is particularly suitable for the high speed and large displacement of the inner shear plate 2, and can effectively improve the application range of the viscous damping wall to meet the needs of most engineering applications.

[0046] The side liquid storage chamber 4 is connected to the shear steel box 5 through the slot 5-2 opened on the side plate of the shear steel box 5. The slot 5-2 on the side plate 5-1 of the shear steel box is a circular hole structure. When the volume inside the side shear steel box 5 increases, the viscous damping liquid 8 in the side liquid storage chamber 4 can be quickly replenished into the shear steel box 5 laterally, and when the volume inside the side shear steel box 5 decreases, the viscous damping liquid 8 in the shear steel box 5 can be quickly filled into the side liquid storage chamber laterally.

[0047] The working process of this embodiment is as follows: Figure 2 As shown, when an earthquake causes relative displacement between the upper and lower floors, the inner shear plate 2 moves left and right within the shear steel box 5, shearing the viscous damping fluid 8 between the inner shear plate 3 and the shear steel box 5, thereby generating a damping force and dissipating energy. The upper liquid storage chamber 3 and the volume compensation bladder 7 within the side liquid storage chamber 4 compensate for the volume changes in the left and right chambers caused by the movement of the inner shear plate 2. The volume compensation bladder 7 within the side liquid storage chamber 4 rapidly absorbs and compensates for the volume changes in the left and right chambers caused by the movement of the inner shear plate 2 through expansion and contraction. This shifts vertical long-distance compensation to lateral short-distance, rapid compensation, shortening the compensation distance by more than 10 times and eliminating the vacuum-like cavity and air inhalation problems caused by untimely compensation. This design is particularly suitable for situations where the inner shear plate 2 experiences high speeds and large displacements, effectively expanding the applicability of viscous damping walls and meeting the requirements of most engineering applications.
