Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building walls, and particularly relates to a shock isolation viscous damping wall. BACKGROUND

[0002] The viscous damping wall is a damping device which can be installed between structural layers as a wall. The relative movement between the structural layers is used to play the energy dissipation role of the viscous damping wall.

[0003] Compared with other types of energy dissipation and shock absorption devices, the viscous damping wall has the following characteristics: 1) easy to manufacture and install, without complex devices and special materials; 2) the damping force of the damping wall can be adjusted by changing the viscosity of the viscous liquid, the distance between the inner and outer steel plates and the area of the steel plate; 3) since the contact area between the wall and the viscous material is large, the viscous damping wall can absorb more seismic energy; 4) the damping wall can be arranged at the wall position of a building, and after installation, the use function of the building is not affected; 5) the viscous damping wall can not only be used as an energy dissipation and shock absorption component of a newly built multi-story, high-rise and super high-rise building structure, but also can be used for structural seismic reinforcement and post-earthquake repair.

[0004] The existing viscous damping wall has a single function, low flexibility and cannot be adjusted, and how to further expand the function of the viscous damping wall on the basis of the existing technology is a technical problem to be solved by the technical scheme of the present application.

Detailed Implementation

[0044] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0045] Please see Figures 1 to 8 In this embodiment of the invention, a seismic isolation viscous damping wall is provided, the damping wall comprising:

[0046] The wall includes an upper wall 1 and a lower wall 2, with a support column 3 between the upper wall 1 and the lower wall 2. The support column 3 is generally made of reinforced concrete and has a certain degree of flexibility when subjected to external forces, that is, there may be misalignment between the upper wall 1 and the lower wall 2.

[0047] A movable wall 5 connected to the upper wall 1 has clamps 12 embedded on both sides and a support plate 13 inside the movable wall 5, with the support plate 13 and the clamps 12 slidably connected.

[0048] A movable wall 5 is provided on the side of the upper wall 1 near the lower wall 2. A clamp 12 is embedded in the movable wall 5. The clamp 12 can move relative to the movable wall 5. The range of movement is generally very small and will not detach from the movable wall 5. The clamp 12 is installed on the support plate 13 inside the movable wall 5.

[0049] An adjustment assembly 16 is disposed between the support plate 13 and the clamping plate 12; wherein the cross section and side section of the clamping plate 12 are both right-angled trapezoids;

[0050] The purpose of the adjusting component 16 is to adjust the range of motion of the clamping plate 12 relative to the movable wall 5. The cross-section and side section of the clamping plate 12 are both right-angled trapezoids. When the clamping plate 12 is adjusted so that the thicker part of the clamping plate 12 is under compression, the pressure between the clamping plate 12 and the lower wall 2 increases. At this time, under the same coefficient of friction, the friction force is greater. When the clamping plate 12 is adjusted so that the thinner part of the clamping plate 12 is under compression, the pressure between the clamping plate 12 and the lower wall 2 decreases. At this time, under the same coefficient of friction, the friction force is smaller.

[0051] A limiting wall 4 is connected to the lower wall 2. A base 21 is installed in the limiting wall 4. A sealing door 22 is hinged to one end of the base 21. A centripetal component 23 is provided inside the base 21. A locking component is provided at the hinged end of the base 21 away from the base 21.

[0052] The limiting wall 4 is generally a relatively fixed wall, and is regarded as a reference body (stationary) during the relative movement of the upper wall 1 and the lower wall 2. The limiting wall 4 is provided with a centripetal component 23, which rotates when vibration occurs, and further improves the stability of the limiting wall 4 according to the principle of conservation of angular momentum.

[0053] like Figure 2 As shown, in one example of the technical solution of the present invention, during the misalignment of the upper wall 1 and the lower wall 2, the friction between the limiting wall 4 and the limiting wall 4 can improve the stability of the building, which is also the working principle of the seismic isolation viscous damping wall; by default, as described in the prior art, the relative sliding surfaces of the upper wall 1 and the lower wall 2 are filled with damping material.

[0054] When vibration occurs, the adjusting component 16 adjusts the clamping plate 12 so that the thicker part of the clamping plate 12 is in a compressed state. At this time, the friction between the movable wall 5 and the limiting wall 4 increases, and the misalignment process between the upper wall 1 and the lower wall 2 can be controlled. On this basis, the centripetal component 23 works to ensure the stability of the limiting wall 4 through the principle of conservation of angular momentum.

[0055] like Figure 2 As shown, in a preferred embodiment of the technical solution of the present invention, the two sides of the support plate 13 are fixedly connected with a first optical axis 14, the clamping plate 12 has a hole at the position corresponding to the first optical axis 14, and the first optical axis 14 is slidably connected to the clamping plate 12; a first spring 15 is sleeved on the first optical axis 14.

[0056] The above content defines the connection relationship between the support plate 13 and the clamping plate 12. The clamping plate 12 and the support plate 13 can move relative to each other. The way of the translation is that the first optical axis 14 on the support plate 13 slides relative to each other along the through hole on the clamping plate 12, thereby realizing relative translation. In order to ensure that the translation process is smoother, damping, namely the first spring 15, can be added.

[0057] It is worth mentioning that if the first optical axis 14 is connected to the clamping plate 12 and the support plate 13 has an opening, then the two first optical axes 14 can limit each other, but the sliding stroke will also be reduced.

[0058] Please see Figures 1 to 5 As a preferred embodiment of the technical solution of the present invention, the adjustment component 16 includes:

[0059] A slide block 18 is slidably connected to the support plate 13; the slide block 18 is externally connected to a transmission assembly; the transmission assembly includes a lead screw; the slide block 18 is connected to the lead screw, and when the lead screw rotates, it can drive the slide block 18 to slide in the support plate 13.

[0060] Rotate the third gear 17 connected to the slide block 18;

[0061] The first pin 1701 is disposed on the third gear 17;

[0062] A limiting seat 1901 is slidably connected to the clamping plate 12, and a rotating seat 19 is hinged on the limiting seat 1901; the limiting seat 1901 and the clamping plate 12 are connected by a telescopic rod.

[0063] A push rod 20 is hinged to the first pin 1701, and the push rod 20 is slidably connected to the rotary seat 19;

[0064] A rack 1301 is provided on one side of the support plate 13, and the third gear 17 cooperates with the rack 1301;

[0065] The push rod 20 engages with the inclined surface of the clamping plate 12 near the support plate 13.

[0066] In one embodiment of the technical solution of the present invention, the transmission component drives the slide 18 to translate. During the translation process, the rotation drives the third gear 17 to translate. During the translation process, the third gear 17 rotates under the action of the rack 1301. The third gear 17 drives the push rod 20 to slide relative to the rotating seat 19 through the first pin 1701. During the sliding process, it drives the rotating seat 19 and its limiting seat 1901 to move up and down along the clamping plate 12. The component connected to the clamping plate 12 is the limiting seat 1901. During the translation process between the limiting seat 1901 and the clamping plate 12, the distance between them can change. Therefore, a telescopic rod is provided. It should be noted that the telescopic rod can also be replaced by a spring.

[0067] When the push rod 20 moves to the lower position, it presses the thicker part of the clamping plate 12. At this time, the friction between the clamping plate 12 and the limiting wall 4 increases. When the push rod 20 moves to the upper position, it presses the thinner part of the clamping plate 12. At this time, the friction between the clamping plate 12 and the limiting wall 4 decreases.

[0068] like Figure 7 As shown, in a preferred embodiment of the technical solution of the present invention, the base 21 is provided with a door seat 2101, and the sealing door 22 is hinged to the door seat 2101; the end of the sealing door 22 away from the door seat 2101 is provided with a pressure plate 2201.

[0069] The door 22 and the door seat 2101 are hinged together to form a revolving door structure.

[0070] like Figure 8 As shown, in one embodiment of the technical solution of the present invention, the centripetal component 23 includes:

[0071] First gear 6; the first gear 6 is externally connected to a power source, and a transmission key shaft 7 is installed on the output shaft of the power source;

[0072] A second transmission frame 11 is mounted on the transmission key shaft 7;

[0073] The second gear 8 is rotatably connected to the end of the second transmission frame 11, and the second gear 8 engages with the first gear 6.

[0074] The second gear 8 is externally connected to the first transmission frame 10, and the end of the first transmission frame 10 is provided with an end plate 9.

[0075] As described above, the function of the centripetal component 23 is to provide a stable angular momentum. Therefore, the main motion of the centripetal component 23 is rotation. The power source can be a motor, and a transmission key shaft 7 is installed on the output shaft of the motor. The transmission key shaft 7 can drive the second transmission frame 11 to rotate. During the rotation of the second transmission frame 11, the second gear 8 rotates around the first gear 6. During the rotation of the second gear 8, it will rotate on its own axis under the action of the first gear 6. At this time, it can drive the second transmission frame 11 to rotate.

[0076] Based on this, a rotating motor can be installed on the end plate 9 to further provide angular momentum, thereby ensuring stability.

[0077] like Figure 7 As shown, in a preferred embodiment of the technical solution of the present invention, the locking component includes:

[0078] The clamp 24 is slidably connected to the base 21;

[0079] A second optical axis 27 is installed on the base 21, and a blind hole is provided on the clamp 24 at the position corresponding to the second optical axis 27; a second spring 28 is sleeved on the second optical axis 27.

[0080] A wheel seat 25 is installed on the clamp 24, and a rotating wheel 26 is provided on the wheel seat 25. The rotating wheel 26 cooperates with the pressure plate 2201.

[0081] The aforementioned centripetal component 23 requires regular maintenance; therefore, a sealing door 22 is required. The sealing door 22 must simultaneously ensure convenience and safety. Convenience refers to the ability to open it quickly for testing, while safety means that, in addition to being able to open it quickly, it is also necessary to prevent parts in the centripetal component 23 from falling off.

[0082] In one embodiment of the technical solution of the present invention, a press-to-open sealing door 22 is adopted. When the operator presses the sealing door 22, the sealing door 22 presses the rotating wheel 26 through the pressure plate 2201. At this time, under the action of the pressure plate 2201, the rotating wheel 26 drives the clamp 24 to move along the second optical axis 27. When the pressure plate 2201 pushes the clamp 24 into the cavity in the base 21, the sealing door 22 can be opened. This press-to-open process is very convenient. Moreover, in actual use, the centripetal component 23 itself will continuously impact the sealing door 22 from the inside under the action of vibration. At this time, the sealing door 22 is in a locked state and cannot be opened, thus ensuring safety.

[0083] In a preferred embodiment of the technical solution of the present invention, the locking component further includes:

[0084] The magnetic base 29 is installed on the clamp 24 and the base 21, and the magnetic base 29 installed on the clamp 24 and the magnetic base 29 installed on the base 21 are at the same height.

[0085] The restoring force of the clamp 24 is provided by the second spring 28. In order to slow down the return speed of the second spring 28, the technical solution of the present invention adds a magnetic seat 29 that cooperates with it, which effectively reduces the return speed of the clamp 24, so that when the staff presses to a certain extent, there is enough time to open the sealing door 22.

[0086] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0087] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
