When these buildings are affected by external factors such as earthquakes and wind loads, they will produce large vibrations and noise, which will affect the safety of the buildings and the comfort of the users. In order to reduce these effects, dampers are widely used in building structures as an important shock absorption, noise reduction and earthquake resistance device. Although the traditional building damper amplifier can reduce the impact of vibration and noise to a certain extent, in actual applications, because the building is a reinforced concrete structure, its safe deformation is relatively small.

[0018] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0019] It should be noted that all components in the technical solution of this application require the necessary additional facilities of water supply, oil supply, electricity supply and gas supply to be driven and / or controlled. If there is no further explanation, it is assumed that the existing technology is used and equipped without special explanation.
[0020] It should be noted that, in order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0021] Depend on Figure 1-2 A damper amplifying device shown is fixedly installed in the frame structure of the building, including an amplifying rod 3, and the frame structure includes a column 1 and a plurality of beams 2 arranged parallel to each other; the two ends of the lower beam 2 are respectively fixedly connected to the two columns 1, one end of the upper beam 2 is rotatably connected to the column 1, one end of the amplifying rod 3 is rotatably connected to one end of the lower beam 2, and the other end of the amplifying rod 3 is slidably connected to the upper beam 2, and a push rod 4 is rotatably connected to the middle part of the amplifying rod 3, one end of the push rod 4 is rotatably connected to the column 1, a damping assembly is arranged between one end of the amplifying rod 3 and the column 1 rotatably connected to the push rod 4, one end of the damping assembly is rotatably connected to the beam 2, and the other end of the damping assembly is rotatably connected to the top surface of the lower beam 2.
[0022] Furthermore, the bottom end of the amplifying rod 3 can replace the installation point, so that the amplifying rod 3 can be installed on the side of the column 1 away from the push rod 4. The amplifying rod 3 is rotatably connected to the column 1, so that when the column 1 vibrates and deforms with the entire building, the angle between the amplifying rod 3 and the column 1 is greater than the angle between the amplifying rod 3 and the beam 2, so that the amplifying rod 3 pushes the upper beam 2 a greater distance, thereby pulling the first damper 9 and the second damper 11 a greater distance, thereby achieving an output of greater damping force.
[0023] The utility model can convert the lateral deformation of the building frame into the deflection of the amplifying rod 3, and finally pull the damping component to balance it through the upper crossbeam 2, so as to improve the support degree of the lateral force of the building by using the larger deformation of the damping component.
[0024] To further optimize the solution, the magnifying rod 3 is arranged at an angle, and the top of the magnifying rod 3 is arranged close to the column 1 which is rotatably connected to the push rod 4. The top of the magnifying rod 3 is fixedly connected to two fixed plates 5, and two rotating shafts 6 are symmetrically rotatably connected between the two fixed plates 5. The two rotating shafts 6 are respectively in sliding contact with the top and bottom surfaces of the beam 2. During the working process, the two rotating shafts 6 are either in sliding contact with the beam 2 at the same time or any one of them is in sliding contact with the beam 2 to realize lifting or pressing down the beam 2.
[0025] Furthermore, the side surfaces of the column 1 and the side surfaces of the amplifying rod 3 are respectively and evenly spacedly fixedly connected with a number of connecting shafts, which are used to hinge the column 1 or the amplifying rod 3 with both ends of the push rod 4, and are used to adjust the fulcrum position of the push rod 4 to push the amplifying rod 3 to swing, thereby being able to adjust the swing amplitude of the amplifying rod 3, thereby improving the operation of the damper, and thus increasing the amplification factor of the damper.
[0026] Further optimized solution, the damping assembly includes a connecting rod 7, the top of the connecting rod 7 is hinged to the upper cross beam 2 through the first hinge seat 8, the bottom surface of the connecting rod 7 is fixedly connected to the first damper 9, one end of the first damper 9 is hinged to the second hinge seat 10, the side of the connecting rod 7 is rotatably connected to the second damper 11, one end of the second damper 11 is hinged to the third hinge seat 12, the third hinge seat 12 and the second hinge seat 10 are respectively fixedly connected to the top surface of the lower cross beam 2, the second damper 11 is tilted, and the first damper 9 is vertically set. The connecting rod 7 can be stably supported by the first damper 9 and the second damper 11, so that a stable frame is formed between the damping assembly, the push rod 4 and the amplifying rod 3 without external force.
[0027] According to a further optimization scheme, the first damper 9 and the second damper 11 are liquid or hydraulic dampers, and the first damper 9 and the second damper 11 can generate damping in both directions, so as to offset the lateral force of the device, and a plurality of second dampers 11 are provided, and the damping force is increased by increasing the number of second dampers 11.
[0028] According to a further optimized solution, the connecting rod 7, the amplifying rod 3 and the push rod 4 are all made of aluminum alloy, which reduces the weight of the utility model and improves the structural strength of the device.
[0029] The working process of this embodiment is as follows:
[0030] When the utility model is installed in the frame of a building, when the building is affected by strong winds, it will tilt. The tilt of the building will also push the column 1 to tilt. Because the column 1 is a reinforced concrete structure, its reasonable deformation is known to be relatively small. In this case, the damper for balancing the lateral force of the building will have too small a damping force due to the small withdrawal distance. It is necessary to increase the number and specifications of the dampers, resulting in increased costs. The column 1 of the present application will push the amplifying rod 3 due to the side tilt, and the amplifying rod 3 will swing along the rotating connection between it and the top surface of the lower beam 2. During the swinging process of the amplifying rod 3, the two rotating shafts 6 will be driven to swing at the same time. The rotating shaft 6 will move along the bottom surface of the upper beam 2 and push the end of the upper beam 2 close to the amplifying rod 3 to tilt up, and then pull the connecting rod 7 to drive the first damper 9 and the second damper 11. The first damper 9 and the second damper 11 respectively balance the lateral force through the damping force generated by their operation, and when the torsion of the column 1 is restored, the push rod 4 is pulled in the reverse direction to drag the amplifying rod 3 in the reverse direction, and the restoring force is damped and balanced again, so as to achieve stable maintenance of the building's swing.
[0031] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
