Description

Technical Field

[0001] The utility model relates to the technical field of earthquake resistance of building engineering, in particular to a viscous damper supporting device. Background Art

[0002] Since the 1970s, people have gradually begun to apply mild steel, viscous dampers, etc. to structural engineering such as buildings, bridges, and railways, using dampers to dissipate unpredictable earthquake energy.

[0003] With the increasing demand for the height, width, complexity and energy dissipation and shock absorption capacity of urban buildings in the development of modern society, the traditional single energy dissipation and shock absorption technology has been gradually replaced by the combined energy dissipation and shock absorption technology of two or more units. Since the combined energy dissipation and shock absorption technology has the advantages of multiple energy dissipation and shock absorption technologies, and the shock absorption design is more flexible and diverse, it is more suitable for the needs of the times of modern urban development and meets people's subjective wishes for buildings.

[0004] For example, the patent (CN212224273U) discloses an assembled energy dissipation and shock absorption support device with a viscous damper, which includes two supporting members arranged opposite to each other, and the two ends of the two supporting members are movably connected with a fixed support, and the fixed support is used to connect the building. There are also several viscous dampers between the two supporting members. The utility model has high assembly, simple and reasonable structure, fast construction speed, low construction cost, good implementation effect, reliable construction quality, can effectively ensure installation accuracy, ensure the effective performance of the seismic performance of the building, and achieve the purpose of energy dissipation and shock absorption. At the same time, it has the advantages of full assembly, easy installation, easy replacement of damage after earthquake, low installation difficulty, low cost, easy transportation, wide application range of construction, etc., and can be widely used in frame concrete structure buildings with seismic requirements.

[0005] When using the above technology, it was found that the following technical problems exist in the prior art: When the building needs to be earthquake-resistant in the prior art, the viscous damper is easily compressed vertically to the extreme position. Since the telescopic distance of the viscous damper is limited, when the viscous damper is compressed to the extreme position, it will produce unpredictable impact force on the structure connected to it, thereby shortening the service life of the damper. Therefore, during the design and installation process, the maximum bearing capacity and working range of the damper should be fully considered, and appropriate protective measures should be taken to prevent it from being compressed to the head, so as to further improve the earthquake resistance of the building. To this end, we design a viscous damper support device to provide another technical solution to the above technical problems. Utility Model Content

[0006] Based on this, it is necessary to provide a viscous damper support device to address the above technical problems. The top end of the main flexible support member is fixed to the upper building, and the bottom end of the slave flexible support member is fixed to the lower building. When the upper building needs to be earthquake-resistant, the upper building impacts the main flexible support member, so that the main flexible support member is compressed in the direction of the slave flexible support member, and the main rotating block and the slave rotating block rotate at the same time. The earthquake-resistant mechanism is arranged between the main flexible support member and the slave flexible support, which effectively provides earthquake-resistant buffering effect for the upper building.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A viscous damper support device comprises a mounting frame, wherein the mounting frames are two, a main rotating block and a slave rotating block are rotatably connected inside the mounting frames, the main rotating block and the slave rotating block rotate crosswise, a main flexible support member is fixed between the two main rotating blocks, a slave flexible support member is fixed between the two slave rotating blocks, a second connecting block is fixed at the top end of the main flexible support member, a first connecting block is fixed at the bottom end of the slave flexible support member, and an anti-seismic mechanism is arranged between the main flexible support member and the slave flexible support member;

[0009] The anti-seismic mechanism includes a viscous damper, both ends of the bottom end of the main flexible support are fixed with fixed hinge supports, the inner side of the fixed hinge supports is rotatably connected with the viscous damper, and both ends of the top end of the secondary flexible support are slidably connected with sliding hinge supports, and the inner side of the sliding hinge supports is rotatably connected with the viscous damper;

[0010] An arc-shaped guide rod is fixed inside the flexible support member, and two ends of the outer side of the arc-shaped guide rod are respectively slidably connected with the sliding hinge support, and two ends of the outer side of the arc-shaped guide rod are sleeved with springs.

[0011] As a preferred embodiment of the viscous damper support device provided by the utility model, the ends of the two springs that are away from each other are fixed to the flexible support member, and the ends of the two springs that are close to each other are fixed to the sliding hinge support.

[0012] As a preferred implementation of the viscous damper support device provided by the utility model, the main flexible support member and the secondary flexible support member are deformable.

[0013] It can be seen without a doubt that the above-mentioned technical solution of the present application can definitely solve the technical problem to be solved by the present application.

[0014] At the same time, through the above technical solutions, the utility model has at least the following beneficial effects:

[0015] The utility model provides a viscous damper support device, which buffers the main flexible support member through the viscous damper, thereby effectively buffering small aftershocks. When the sway amplitude of the upper building is large, when the viscous damper is compressed to the maximum bearing capacity and the extreme point of the working range, the bottom ends of the two viscous dampers buffer in the direction away from the flexible support member, and the spring effectively absorbs the impact force brought by the viscous damper.

[0016] The viscous damper is effectively protected and buffered by the compression force of the spring to prevent the viscous damper from being directly subjected to a compression force greater than its own, which would cause the performance of the viscous damper to deteriorate or be damaged, thereby protecting the viscous damper and increasing its service life.

[0027] Embodiment 1

[0028] Reference Figure 1-Figure 4 A viscous damper support device comprises a mounting frame 4, wherein the mounting frame 4 is two, wherein a main rotating block 9 and a slave rotating block 10 are connected to the mounting frame 4 in rotation, wherein the main rotating block 9 and the slave rotating block 10 rotate crosswise, wherein a main flexible support member 1 is fixed between the two main rotating blocks 9, wherein a slave flexible support member 2 is fixed between the two slave rotating blocks 10, wherein the main flexible support member 1 and the slave flexible support member 2 have certain elasticity or deformability, wherein a second connecting block 12 is fixed to the top end of the main flexible support member 1, wherein a first connecting block 3 is fixed to the bottom end of the slave flexible support member 2, and an anti-seismic mechanism is arranged between the main flexible support member 1 and the slave flexible support member 2;

[0029] When installation is required, the top end of the main flexible support member 1 is fixed to the upper building, and the bottom end of the slave flexible support member 2 is fixed to the lower building. When the upper building needs to be earthquake-resistant, the upper building impacts the main flexible support member 1, so that the main flexible support member 1 is compressed in the direction of the slave flexible support member 2, and the main rotating block 9 and the slave rotating block 10 rotate. The earthquake-resistant mechanism is arranged between the main flexible support member 1 and the slave flexible support member 2, so as to effectively provide earthquake-resistant buffering effect for the upper building.

[0030] The anti-seismic mechanism includes a viscous damper 6. Both ends of the bottom end of the main flexible support 1 are fixed with fixed hinge supports 5. The inner side of the fixed hinge supports 5 is rotatably connected with the viscous damper 6. Both ends of the top end of the secondary flexible support 2 are slidably connected with sliding hinge supports 7. The inner side of the sliding hinge supports 7 is rotatably connected with the viscous damper 6.

[0031] An arc-shaped guide rod 8 is fixed inside the flexible support member 2, and the two ends of the outer side of the arc-shaped guide rod 8 are respectively slidably connected to the sliding hinge support 7, and the two ends of the outer side of the arc-shaped guide rod 8 are sleeved with springs 11;

[0032] When the upper building needs to be earthquake-resistant, the two viscous dampers 6 buffer the main flexible support 1, thereby effectively buffering small aftershocks. When a larger earthquake occurs, the upper building sways more, and the viscous damper 6 buffers the main flexible support 1. When the viscous damper 6 is compressed to the maximum bearing capacity and the extreme point of the working range, the bottom ends of the two viscous dampers 6 buffer in the direction away from the flexible support 2. At this time, the spring 11 effectively absorbs the impact force brought by the viscous damper 6, and the compression force of the spring 11 is greater than the compression force of the viscous damper 6.

[0033] The viscous damper 6 is effectively protected by the compression force of the spring 11, so as to prevent the viscous damper 6 from being directly subjected to a compression force greater than itself, which would cause the performance of the viscous damper 6 to deteriorate or be damaged;

[0034] One end of the two springs 11 that is away from each other is fixed to the flexible support 2, and one end of the two springs 11 that is close to each other is fixed to the sliding hinge support 7;

[0035] The spring 11 effectively protects the viscous damper 6 and helps to absorb the remaining impact force of the viscous damper 6 .

[0036] The use process of a viscous damper support device provided by the utility model is as follows: when encountering an earthquake, the impact force of the upper building drives the main flexible support member 1 to compress the secondary flexible support member 2, and the main flexible support member 1 and the secondary flexible support member 2 have a certain degree of variability, thereby driving the main flexible support member 1 to impact the viscous damper 6, and the two viscous dampers 6 buffer the main flexible support member 1, thereby effectively buffering small aftershocks. When the swing amplitude of the upper building is large, the viscous damper 6 buffers the main flexible support member 1. When the viscous damper 6 is compressed to the maximum bearing capacity and the extreme point of the working range, the bottom ends of the two viscous dampers 6 buffer in the direction away from each other along the secondary flexible support member 2, and the spring 11 effectively absorbs the impact force brought by the viscous damper 6;

[0037] When the impact force of the upper building is absorbed, the two viscous dampers 6 are driven by the restoring force of the spring 11 to slide and reset in a direction close to each other, and the viscous dampers 6 drive the main flexible support 1 to reset.

[0038] The preferred embodiments of the utility model disclosed above are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
