Description

Technical Field

[0001] The utility model relates to the technical field of building structure vibration control, in particular to an assembled tuned mass damper. Background Art

[0002] With the development of the construction industry, there are more and more tall and long-span buildings. The problem of controlling the vibration of these structures has attracted increasing attention from the engineering and academic communities. The principle of tuned mass dampers is to absorb and dissipate vibration energy by using mass blocks, springs, and damping components. Because tuned mass dampers can effectively attenuate the dynamic response of structures, and because they are simple in structure, easy to install, and economical and practical, they have been widely used in high-rise and long-span buildings.

[0003] The Chinese invention patent application number CN202311712991.1 discloses an assembled multi-tuned mass damper and design method. The damper includes a base plate, several groups of mass-spring system components, and several eddy current damping devices. The several groups of mass-spring system components are independently arranged on the base plate. Each group of mass-spring system components is an independent unit, having a combined mass component and a spring component. The combined mass component can directly abut against the base plate through the spring component and can move up and down independently and freely relative to the base plate; the several eddy current damping devices are distributed between two adjacent groups of mass-spring system components and respectively cooperate with the combined mass components in the two groups of mass-spring system components to jointly dissipate vibration energy. The present invention can effectively improve the vibration control performance and robustness of the damper. Combined with the assembled structural design, it facilitates the convenience of the damper in practical applications and provides a simpler, more effective, economical and high-energy solution for the engineering application of the damper.

[0004] However, the existing assembled tuned mass damper has a fixed installation position of the plug-in mass block, which is inconvenient to adjust and assemble, and thus it is not convenient to freely adjust the performance of the damper itself. Therefore, we propose an assembled tuned mass damper to solve the above problems. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figures 1-6 In the existing tuned mass damper, the installation position of the plug-in mass block is fixed, which is inconvenient to adjust and assemble, and thus it is not convenient to freely adjust the performance of the damper itself. In order to solve this technical problem, this embodiment discloses the following technical content;

[0029] An assembled tuned mass damper includes a limit plate 1, a guide rod 2, a linear bearing 3, a flat plate 4, a modular box 5, a plug-in plate slot 6, a socket 7, a limiting ring 8, a spring 9, a damping assembly 10, a lower base plate 11, a first plug-in plate mass block 12, a second plug-in plate mass block 13, a pin 14 and a support rod 15. The guide rod 2 runs through the interior of the limit plate 1, and an assembled adjustable mass module is provided below the limit plate 1. The assembled adjustable mass module includes a flat plate 4, a modular box 5, a plug-in plate slot 6, a socket 7, a first plug-in plate mass block 12, a second plug-in plate mass block 13, a pin 14 and a support rod 15. The inner side of the flat plate 4 is fixed with a modular box 5. The modular box 5 is provided with a plug-in slot 6 vertically, and a plug-in hole 7 is provided horizontally inside the modular box 5. The first plug-in plate mass block 12 is installed inside the plug-in plate slot 6, and the second plug-in plate mass block 13 is connected to the outside of the first plug-in plate mass block 12. The first plug-in plate mass block 12 is fixed in the modular box 5 by a pin 14. The plug-in plate slots 6 are provided at equal intervals inside the modular box 5.

A limiting ring 8 is fixed to the four corners of the lower surface of the plate 4. The top end of the spring 9 is fixedly connected to the plate 4. The top and bottom ends of the damping assembly 10 are respectively installed on the lower surface of the plate 4 and the upper surface of the lower base plate 11;

[0030] Since the board slots 6 are evenly spaced inside the modular box 5, the operator can select the board slot 6 at the appropriate position to install the first board mass 12, adjust the assembly, insert the first board mass 12 into the selected board slot 6, and then insert the pin 14 into the socket 7 to restrain the first board mass 12.

[0031] After installing the first plug-in plate mass block 12, install the limit plate 1 on the flat plate 4, with the guide rod 2 passing through the interior of the limit plate 1;

[0032] Example 2: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Example 1. The modular box 5 has reserved slots 6 for inserting boards.

[0035] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiment 1. After the pin shaft 14 is inserted into the socket 7, it is inconvenient to remove the pin shaft 14. In order to solve this technical problem, this embodiment discloses the following technical content;.

[0036] like Figure 4 As shown, a support rod 15 is fixed to the outer end of the pin 14. After the pin 14 is fully inserted into the modular box 5, when the pin 14 needs to be removed, a finger is inserted into the hole at the outer end of the pin 14, the finger hooks the support rod 15, and the support rod 15 is pulled outward to pull out the pin 14;

[0037] The above completes a series of operations of the assembled tuned mass damper. The contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
