Description

Technical Field

[0001] This invention relates to the field of building seismic isolation technology, and in particular to a plate-type horizontal damper and damping method for buildings. Background Technology

[0002] In existing technologies, such as the wall structure and building body disclosed on the Chinese patent website with publication number CN 118029579 B, hydraulic cylinders are used as the main component of the damper to isolate or reduce vibration in buildings. However, this method of achieving damping action through hydraulic cylinders has the following shortcomings:

[0003] Since the hydraulic cylinder is the main structure of the damper, its damping capacity will increase with the size of the building. The larger the building, the more dampers are needed. This makes the overall weight of the damper always high, sometimes reaching several tons. This will bring great difficulties to the transportation, installation and support of the damper. Summary of the Invention

[0004] Based on existing technical problems, this invention proposes a building plate-type horizontal damper and a damping method.

[0005] The present invention proposes a building plate-type horizontal damper, including a hinged seat for mounting and connecting the building.

[0006] The surfaces of the two hinge seats are respectively hinged to a U-shaped plate and a damping plate that reciprocates along the center line of the U-shaped plate.

[0007] Adjustable spring assemblies are laterally installed on both sides of the end of the U-shaped plate, and the two side surfaces of the damping plate are elastically constrained by the spring assemblies at the middle of the two spring assemblies.

[0008] Both sides of the damping plate are provided with friction inner plates with slope A at both ends.

[0009] When the building vibrates, the damping plate drives the inner friction plate to reciprocate along the centerline of the damping plate. The surface of the inner friction plate elastically squeezes and rubs against the spring assembly, converting the vibration into elastic potential energy which is stored or released onto the inner friction plate to achieve the damping action.

[0010] Preferably, a protective shell is fitted onto the outer surface of the U-shaped plate and the damping plate, and the other end of the damping plate extends to the outside of one end of the protective shell.

[0011] Through the above technical solutions, the protective shell can protect its internal structure and prevent dust and impurities from entering its interior in the outdoor environment.

[0012] Preferably, the spring assembly includes a sleeve that is movably fitted between the two side surfaces of the protective shell and the outer surface of the U-shaped plate. A spring is movably disposed inside the sleeve. Both ends of the spring are provided with cover plates that are slidably connected to the inner wall of the sleeve. An adjusting bolt extending to the other side of the protective shell is movably disposed at the axis of the cover plate. One end of the adjusting bolt is threadedly connected to an adjusting nut located on the outer surface of the cover plate. By tightening or loosening the adjusting bolt, the elastic compressive force of the spring on the friction inner plate can be adjusted.

[0013] The above technical solution facilitates the installation of springs and the adjustment of their elasticity, allowing the spring force to be adjusted according to actual usage conditions. Adjustment can be achieved simply by turning the adjusting bolt or adjusting nut.

[0014] Preferably, the spring includes, but is not limited to, any one of a disc spring, a linear spring, a ring spring, or a wave spring.

[0015] The above technical solution allows for the replacement of different spring types according to the damping requirements of different buildings, thus meeting the needs of different application scenarios.

[0016] Preferably, a limiting sleeve is provided at the gap between the outer surface of the adjusting bolt and the inner wall of the spring.

[0017] When the adjusting bolt is tightened to the maximum deformation of the spring, the cover plates located at both ends of the spring contact the limiting spacer, thus limiting the adjusting bolt.

[0018] Through the above technical solution, the limiting spacer can fully protect the spring and prevent the spring from being damaged due to exceeding the maximum deformation.

[0019] Preferably, a heat dissipation frame is provided in the gap between the inner surface of the U-shaped plate and the friction inner plate, and the heat dissipation frame is formed by the mutual fixed connection of the transverse heat dissipation strips and the longitudinal heat dissipation strips.

[0020] Through the above technical solution, the heat generated by the friction inner plate after extrusion can be dissipated through the gaps between the intersecting horizontal and vertical heat dissipation strips.

[0021] Preferably, an outer friction plate that contacts the surface of the inner friction plate is fixedly installed on the inner surface of the heat dissipation frame. The heat generated by the friction between the surface of the outer friction plate and the surface of the inner friction plate is dissipated through the heat dissipation frame.

[0022] The above technical solution can dissipate the heat converted from the mechanical energy of extrusion friction. This component can be replaced after a certain frequency of use, while other components do not need to be replaced. Replacement is also more convenient due to its light weight.

[0023] Preferably, the surface of the inner friction plate is divided into a tensile damping section, a free-stroke damping section, and a compressive damping section, and the slope A of the tensile damping section and the compressive damping section is in the range of 1°-1.5°.

[0024] Through the above technical solution, the slope A can compress the spring and generate frictional compression force, thereby achieving a damping effect. The slope A is preferably 1° or 1.05°.

[0025] Preferably, when there is no earthquake, the surface of the outer friction plate elastically rubs against the surface of the inner friction plate during its idle travel damping section.

[0026] When an earthquake occurs and the damping plate moves outward, the surface of the outer friction plate elastically rubs against the surface of the tensile damping section of the inner friction plate.

[0027] When an earthquake occurs and the damping plate moves inward, the surface of the outer friction plate elastically rubs against the surface of the compressive damping section of the inner friction plate.

[0028] A damping method for a building plate-type horizontal damper includes step one: installation preparation; installing and connecting the U-shaped plate and the hinge seat at one end of the damping plate to the building.

[0029] Step 2: Adjust the damping force; tighten the adjusting bolt and the adjusting nut with the torque wrench with display, so that the cover plate applies a compressive force to the spring until the preset torque is reached. The spring elastically presses the outer friction plate against the surface of the inner friction plate. Finally, install the protective shell.

[0030] Step 3, Vibration Damping; P1, in the absence of vibration, the damper is in the no-travel damping section, with no displacement and no damping force.

[0031] P2, during tensile vibration, the damper is in the tensile damping section. After the outer friction plate elastically compresses the slope A of the inner friction plate surface, it generates a positive tensile displacement. At this time, the spring is compressed and generates a damping force.

[0032] As the stretching vibration gradually decreases, the outer friction plate elastically compresses the slope A of the inner friction plate surface, resulting in a return displacement. At this time, the spring rebounds and generates a reverse stretching damping force.

[0033] P3. During compression and vibration, the damper is in the anti-compression damping section. After the outer friction plate elastically compresses the slope A of the inner friction plate surface, it generates a positive compression displacement. At this time, the spring is compressed and generates a damping force.

[0034] As the stretching vibration gradually decreases, the outer friction plate elastically compresses the slope A of the inner friction plate surface, resulting in a return displacement. At this time, the spring rebounds and generates a reverse compressive damping force.

[0035] The beneficial effects of this invention are as follows:

[0036] 1. By installing adjustable spring assemblies laterally on both sides of the U-shaped plate's ends, the existing hydraulic cylinder axial damping can be transformed into plate-type radial damping. The spring force can be adjusted according to the actual damping requirements, thus achieving damping effects for different structures. Compared to existing technologies, this eliminates the weight of the hydraulic cylinder and some springs, as well as the necessary hydraulic oil, connections, and control components, thereby achieving weight reduction.

[0037] 2. By setting friction inner plates with slope A at both ends on both sides of the damping plate, it can combine with the radially set spring assembly 4 to compress and dampen the building. When the damping plate reciprocates, it drives the slope A at both ends of the friction inner plate to compress radially with the spring assembly, converting the mechanical energy of radial friction and compression into heat energy, thereby achieving the effect of radial damping.

[0051] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0052] Example 1

[0053] Reference Figures 1-8 A building plate-type horizontal damper includes a hinged base 1 for mounting and connecting the building.

[0054] like Figures 1-2 As shown, a U-shaped plate 2 and a damping plate 3 that reciprocates along the centerline of the U-shaped plate 2 are respectively hinged to the surfaces of the two hinge seats 1. To prevent dust and debris from falling onto the damping plate 3, a protective shell 6 is fitted onto the outer surfaces of the U-shaped plate 2 and the damping plate 3, with the other end of the damping plate 3 extending outside one end of the protective shell 6. The protective shell 6 protects its internal structure, preventing dust and impurities from entering its interior in outdoor environments.

[0055] like Figures 2-4As shown, in order to achieve the damping effect of the building, adjustable spring assemblies 4 are installed laterally on both sides of the end of the U-shaped plate 2. The two sides of the damping plate 3 are elastically limited by the spring assemblies 4 in the middle of the two spring assemblies 4. Both sides of the damping plate 3 are provided with friction inner plates 5 with slope A at both ends.

[0056] Specifically, the damping plate 3 is damped as follows: The spring assembly 4 includes a sleeve 41 movably fitted between the two side surfaces of the protective shell 6 and the outer surface of the U-shaped plate 2. A spring 42 is movably disposed inside the sleeve 41. Both ends of the spring 42 are provided with cover plates 43 that are slidably connected to the inner wall of the sleeve 41. An adjusting bolt 44 extending to the other side of the protective shell 6 is movably disposed at the axis of the cover plate 43. One end of the adjusting bolt 44 is threadedly connected to an adjusting nut 45 located on the outer surface of the cover plate 43. By tightening or loosening the adjusting bolt 44, the elastic compressive force of the spring 42 on the friction inner plate 5 can be adjusted. This facilitates the installation of the spring 42 and the adjustment of its elastic force, allowing the spring force of the spring 42 to be adjusted according to actual usage conditions. Adjustment can be achieved simply by tightening the adjusting bolt 44 or the adjusting nut 45.

[0057] The spring 42 includes, but is not limited to, any one of a disc spring, a linear spring, a ring spring, or a wave spring. Different types of springs 42 can be used to meet the damping requirements of different buildings and to satisfy different application scenarios.

[0058] Furthermore, a limiting sleeve 46 is provided at the gap between the outer surface of the adjusting bolt 44 and the inner wall of the spring 42.

[0059] When the adjusting bolt 44 is tightened to the maximum deformation of the spring 42, the cover plate 43 located at both ends of the spring 42 contacts the limiting spacer 46, limiting the adjusting bolt 44. The limiting spacer 46 can fully protect the spring 42 and prevent damage to the spring 42 due to exceeding the maximum deformation. At the same time, when the friction inner plate 5 reciprocates with damping, and its two ends slide to the edge of the spring assembly 4 after reaching the maximum extension length, the outer end of the limiting spacer 46 abuts against the end face of the cover plate 43, thus confining the spring assembly 4 to the two sides of the friction inner plate 5 and preventing it from sliding out of the friction inner plate 5.

[0060] When the building vibrates, the damping plate 3 drives the inner friction plate 5 to reciprocate along the centerline of the damping plate 3. The surface of the inner friction plate 5 elastically squeezes and rubs against the spring assembly 4, converting the vibration into elastic potential energy and storing or releasing it onto the inner friction plate 5 to achieve the damping action.

[0061] By installing adjustable spring assemblies 4 laterally on both sides of the end of the U-shaped plate 2, the existing hydraulic cylinder axial damping can be transformed into plate-type radial damping. The spring force can be adjusted according to the actual damping conditions, thereby achieving damping effects for different structures. Compared with existing technologies, this eliminates the weight of the hydraulic cylinder and some springs, as well as the necessary hydraulic oil in the cylinder and related connections and control components, thus achieving weight reduction.

[0062] like Figure 2 , Figure 5 as well as Figure 6 As shown, to prevent the heat generated during friction damping of the inner friction plate 5 from being difficult to dissipate, a heat dissipation frame 51 is provided in the gap between the inner surface of the U-shaped plate 2 and the inner friction plate 5. The heat dissipation frame 51 is formed by horizontal heat dissipation strips 511 and vertical heat dissipation strips 512 fixedly connected to each other. The heat generated by the compressed inner friction plate 5 can be dissipated through the gaps where the horizontal heat dissipation strips 511 and the vertical heat dissipation strips 512 intersect.

[0063] Furthermore, a friction outer plate 52, which contacts the surface of the inner friction plate 5, is fixedly installed on the inner surface of the heat dissipation frame 51. The heat generated by the friction between the surface of the outer friction plate 52 and the surface of the inner friction plate 5 is dissipated through the heat dissipation frame 51. This component can dissipate heat converted from the mechanical energy of friction. It can be replaced after a certain frequency of use, while other components do not need to be replaced. Replacement is also easier due to its light weight.

[0064] like Figures 6-8 As shown, in order to enable the damper to have the same damping effect as a hydraulic cylinder, the surface of the friction inner plate 5 is divided into a tensile damping section 53, a free-stroke damping section 54, and a compressive damping section 55. The slope A of the tensile damping section 53 and the compressive damping section 55 is between 1° and 1.5°. Slope A can compress the spring 42, generating a frictional compressive force, thereby achieving a damping effect. The slope A is preferably 1° or 1.10°.

[0065] Specifically, the damping is achieved as follows: when there is no earthquake, the surface of the outer friction plate 52 elastically rubs against the surface of the idle travel damping section 54 of the inner friction plate 5.

[0066] When an earthquake occurs and the damping plate 3 moves outward, the surface of the outer friction plate 52 elastically rubs against the surface of the tensile damping section 53 of the inner friction plate 5.

[0067] When an earthquake occurs and the damping plate 3 moves inward, the surface of the outer friction plate 52 elastically rubs against the surface of the compressive damping section 55 of the inner friction plate 5.

[0068] By setting friction inner plates 5 with slope A at both ends on both sides of the damping plate 3, it can combine with the radially arranged spring assembly 4 to compress and dampen the building. When the damping plate 3 reciprocates, it drives the slope A at both ends of the friction inner plate 5 to compress radially with the spring assembly 4, converting the mechanical energy of radial friction and compression into heat energy, thereby achieving the effect of radial damping.

[0069] Example 2

[0070] Reference Figures 1-12 A damping method for a building plate-type horizontal damper includes step one: installation preparation; such as... Figures 1-6 As shown, the hinge seat 1 at one end of the U-shaped plate 2 and the damping plate 3 is installed and connected to the building.

[0071] Step 2: Adjust the damping force; such as Figure 2 , Figures 3-9 As shown, by tightening the adjusting bolt 44 and the adjusting nut 45 with the torque wrench with display, the cover plate 43 applies a compressive force to the spring 42 until the preset torque is reached. The spring 42 elastically presses the outer friction plate 52 onto the surface of the inner friction plate 5. Finally, the protective shell 6 is installed.

[0072] Step 3, vibration damping; such as Figure 6 , Figure 7 , Figure 10 as well as Figure 12 As shown, P1, in the absence of vibration, the damper is in the no-travel damping section 54, with no displacement and no damping force.

[0073] like Figure 6 , Figure 7 , Figure 9 as well as Figure 12 As shown, during the tensile vibration at P2, the damper is in the tensile damping section 53. After the outer friction plate 52 elastically compresses the slope A of the inner friction plate 5 surface, it generates a positive tensile displacement. At this time, the spring 42 is compressed and generates a damping force.

[0074] As the stretching vibration gradually decreases, the outer friction plate 52 elastically compresses the slope A of the inner friction plate 5 surface, resulting in a return displacement. At this time, the spring 42 rebounds and generates a reverse stretching damping force.

[0075] like Figure 6 , Figure 7 , Figure 11 as well as Figure 12 As shown, during the compression vibration at P3, the damper is in the compression damping section 55. After the outer friction plate 52 elastically compresses the slope A of the inner friction plate 5, it generates a positive compression displacement. At this time, the spring 42 is compressed and generates a damping force.

[0076] As the stretching vibration gradually decreases, the outer friction plate 52 elastically compresses the slope A of the inner friction plate 5 surface, resulting in a return displacement. At this time, the spring 42 rebounds and generates a reverse compressive damping force.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
