Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a horizontally adjustable damping wall. Background Technology

[0002] It is generally composed of a steel box and steel plates inserted inside the steel box. The steel box is rigidly connected to the top of the lower beam, and the steel plates are rigidly connected to the bottom of the upper beam through the upper end plate. The steel box is filled with a high-viscosity viscous material. The steel plates and the upper end plate are an integral whole. Its non-load-bearing characteristics (only providing damping force) and reliable nonlinear viscous damping energy dissipation mechanism make it widely used in super high-rise buildings, hospitals, and important cultural facilities in strong earthquake zones.

[0003] Currently available horizontally adjustable damping walls work by having the viscous material within the steel box slide back and forth laterally when the floors undergo relative displacement, generating viscous shear damping force to dissipate the energy input to the structure by earthquakes or wind loads and reduce the structure's dynamic response. However, they cannot play a role in damping and dissipating energy when the building experiences vertical vibrations. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a horizontally adjustable damping wall, which aims to improve the problem that the upper and lower beams of the damping wall can only move in the horizontal direction and cannot perform vertical damping.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a horizontally adjustable damping wall, comprising a lower beam, a base plate at the top of the lower beam, a second support plate fixedly connected to the top of the base plate, a damping box fixedly connected to the top of the second support plate, damping fluid inside the damping box, an upper beam at the top of the damping box, a top plate at the bottom of the upper beam, a first support plate fixedly connected to the bottom of the top plate, a middle plate slidably connected inside the first support plate, four first bolts threadedly connected to opposite sides of the top plate and the base plate, and an adjustment assembly on the outer surface of the first support plate.

[0006] Preferably, the adjusting assembly includes a plurality of nuts, which are fixedly connected to a first support plate. The first support plate has four connecting slots on its front side, and the intermediate plate has four fixing slots on its front side. Each of the four connecting slots is threaded with a second bolt.

[0007] Preferably, the top four first bolts are threaded to the upper beam, and the bottom four first bolts are threaded to the lower beam.

[0008] Preferably, the outer surface of the intermediate plate is stepped, and the lower half of the intermediate plate is located in the damping box.

[0009] Preferably, the intermediate plate is made of a highly corrosion-resistant board material, and the bottom of the intermediate plate is immersed in damping fluid.

[0010] Preferably, the connecting groove is a plurality of circular grooves connected together, and the connecting groove extends through the front side of the first support plate.

[0011] Preferably, the second bolt passes through the connecting groove and the fixing groove in sequence on its rear side, and the second bolt is threadedly connected to the fixing groove and the nut.

[0012] Preferably, the nuts are grouped into four groups of four, with each group of nuts corresponding to one second bolt.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, a damping plate is set between the upper and lower beams of the building structure. The middle plate of the damping plate is set with a stepped shape, and the inside of the damping box is set to be larger in both length and width than the middle plate. This allows the middle plate to move up and down and left and right in the damping box, solving the problem that the upper and lower beams of the damping wall can only move horizontally and cannot perform vertical shock absorption.

[0015] 2. In this utility model, by setting four corresponding nuts for a second bolt and opening a connecting groove on the first support plate to engage the second bolt, the second bolt can be fixed with different nuts and engaged with different positions of the connecting groove, thereby adjusting the position of the intermediate plate. This solves the problem that the second bolt will loosen and cause depth displacement after long-term use of the intermediate plate. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 An embodiment of this utility model provides a horizontally adjustable damping wall, including a lower beam 1, a base plate 3 at the top of the lower beam 1, a second support plate 7 fixedly connected to the top of the base plate 3, a damping box 8 fixedly connected to the top of the second support plate 7, damping fluid 10 inside the damping box 8, an upper beam 2 at the top of the damping box 8, a top plate 4 at the bottom of the upper beam 2, a first support plate 5 fixedly connected to the bottom of the top plate 4, a middle plate 9 slidably connected inside the first support plate 5, four first bolts 6 threadedly connected to the opposite side of the top plate 4 and the base plate 3, and an adjustment component on the outer surface of the first support plate 5.

[0024] Specifically, when using the device, the top plate 4 and bottom plate 3 are fixed to the upper beam 2 and lower beam 1 respectively by the first bolt 6, thus fixing the device in the building. When the building is subjected to horizontal stress due to strong winds or earthquakes, the middle plate 9 is connected to the upper beam 2 as a whole through the first support plate 5 and the top plate 4, and is thus moved in the damping fluid 10 in the damping box 8. The damping fluid 10 generates reverse resistance to consume vibration energy. When the middle plate 9 is immersed in the damping fluid 10 to a certain depth, its stepped second part is immersed in the damping fluid 10, and its cross-sectional area immersed in the damping fluid 10 increases, significantly improving the damping force and enhancing the energy consumption effect. The middle plate 9 can move up and down and left and right in the damping box 8, thereby reducing the force on the building in both the horizontal and vertical directions. This can effectively reduce structural vibration damage, extend the service life of the building, and solve the problem that the upper and lower beams of the damping wall can only move in the horizontal direction and cannot perform vertical vibration reduction.

[0025] Reference Figure 4 The adjustment assembly includes multiple nuts 12, which are fixedly connected to the first support plate 5. The first support plate 5 has four connecting slots 13 on its front side, and the middle plate 9 has four fixing slots 14 on its front side. The front side of each of the four connecting slots 13 is threaded with a second bolt 11.

[0026] Specifically, by loosening the second bolt 11, the intermediate plate 9 is released from its locking position, allowing it to slide up and down in the first support plate 5. This adjusts the depth of the intermediate plate 9 immersed in the damping box 8 to adapt to different installation environments. After the intermediate plate 9 and the four second bolts 11 slide to the appropriate position in the first support plate 5 and connecting groove 13, the second bolts 11 are aligned with the corresponding nuts 12, and then tightened to lock into the connecting groove 13. This ensures precise positioning and anti-loosening connection of the intermediate plate 9, solving the problem of depth displacement caused by loosening of the second bolts 11 after long-term use of the intermediate plate 9.

[0027] Reference Figure 2 The top four first bolts 6 are threadedly connected to the upper beam 2, and the bottom four first bolts 6 are threadedly connected to the lower beam 1.

[0028] Specifically, when installing the damping wall, the top plate 4 and the bottom plate 3 are fixed to the upper beam 2 and the lower beam 1 in the room body respectively by the first bolt 6, thereby fixing the damping wall in the room body.

[0029] Reference Figure 2 The outer surface of the intermediate plate 9 is stepped, and the lower half of the intermediate plate 9 is located in the damping box 8.

[0030] Specifically, by setting the intermediate plate 9 to a stepped shape, with the cross-section of its bottom being smaller than that of the stepped portion, when the depth of the intermediate plate 9 immersed in the damping box 8 increases to a certain extent, the cross-section of the intermediate plate 9 in the damping liquid 10 increases, significantly improving the damping force and enhancing the energy dissipation effect.

[0031] Reference Figure 3 The intermediate plate 9 is made of a highly corrosion-resistant board, and the bottom of the intermediate plate 9 is immersed in the damping fluid 10.

[0032] Specifically, by making the intermediate plate 9 a highly corrosion-resistant material, when the intermediate plate 9 is placed in the damping box 8, its small cross-section and part of its large cross-section are immersed in the damping liquid 10, thereby preventing damage to the intermediate plate 9.

[0033] Reference Figure 4 The connecting groove 13 is in the shape of multiple circular grooves connected together, and the connecting groove 13 penetrates the front side of the first support plate 5.

[0034] Specifically, the shape of the connecting groove 13 allows the second bolt 11 to be inserted into the connecting groove 13, and to engage with the circular groove of the connecting groove 13 when the second bolt 11 is inserted into the circular groove at different positions, thereby restricting the position of the second bolt 11.

[0035] Reference Figure 4 The second bolt 11 passes through the connecting groove 13 and the fixing groove 14 in sequence on the rear side, and the second bolt 11 is threadedly connected to the fixing groove 14 and the nut 12.

[0036] Specifically, the second bolt 11 passes through the connecting groove 13 and the fixing groove 14, so that one end of the second bolt 11 is engaged in the connecting groove 13, and the other end is threadedly connected to the nut 12, thereby fixing the intermediate plate 9 in the first support plate 5.

[0037] Reference Figure 4 There are four groups of four nuts 12, and each group of nuts 12 corresponds to a second bolt 11.

[0038] Specifically, the connecting groove 13 is also composed of four circular grooves. When the second bolt 11 is engaged in a certain circular groove by adjusting its position, the other end of the second bolt 11 is connected to the nut 12 of the corresponding height.

[0039] Working principle: After the damping plate is installed in the building, when the building is subjected to horizontal stress due to strong winds or earthquakes, the middle plate 9 is moved in the damping fluid 10 in the damping box 8. Whether the middle plate 9 is moved up and down or left and right, the damping fluid 10 can generate reverse resistance to consume vibration energy. When the middle plate 9 is immersed in the damping fluid 10 to a certain depth, its stepped second part is immersed in the damping fluid 10, and its large cross-section section is submerged in the damping fluid 10, thereby significantly increasing the damping force. Under the release of the damping fluid 10, the building is subjected to lateral and vertical stress reduction, which can effectively reduce structural vibration damage and extend the service life of the building.

[0040] When installing the damping plate, the position of the intermediate plate 9 in the first support plate 5 is adjusted according to different installation environments and damping requirements. After the intermediate plate 9 and the four second bolts 11 slide to the appropriate position in the first support plate 5 and the connecting groove 13, the second bolts 11 are aligned with the nuts 12 at the corresponding positions, and then the second bolts 11 are tightened to engage in the connecting groove 13, thereby accurately positioning and preventing loosening of the intermediate plate 9. When the position of the intermediate plate needs to be adjusted after the damping plate is installed, the second bolts 11 are loosened to release the nuts 12, thereby adjusting the position of the intermediate plate and then fixing it again.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
