Description

Technical Field

[0001] This utility model relates to the field of building vibration reduction technology, and in particular to a building structure vibration reduction device. Background Technology

[0002] Existing buildings all require a certain degree of seismic damping structure to prevent natural disasters or emergencies such as earthquakes from causing building swaying. Building seismic damping involves installing energy-dissipating devices in certain parts of the structure. These devices generate friction, bending, and elasto-plastic hysteretic deformation to dissipate or absorb the energy input into the structure by earthquakes, thereby reducing the vibration of the main structure and preventing structural damage or collapse, thus achieving the purpose of seismic control. However, the seismic damping structure of existing building seismic devices is relatively simple, and it is impossible to adjust the overall elastic coefficient during use. As a result, during use, the elastic coefficient may be too large to provide effective buffering, or too small to provide support, leading to instability and damage to the building structure.

[0003] Therefore, we propose a building structure vibration damping device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a building structure vibration damping device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibration damping device for building structures includes a support rod, the lower end surface of which is covered with a friction layer, a set of storage grooves on the side wall of the support rod, a support rod rotatably connected to each of the storage grooves, an extension sleeve sleeved on the outside of the support rod, a damping spring connected between the extension sleeve and the side wall of the support rod, a set of support plates rotatably connected to the upper end surface of the support rod, and an elastic fixing strap sleeved on the lower side of the support rod.

[0007] Preferably, a base is connected to the lower end face of the support rod.

[0008] Preferably, the inner wall surface of the storage groove is covered with a sealing ring structure.

[0009] Preferably, the lower end of the extension sleeve is rotatably connected to a support leg, and the rotatable connection between the support leg and the extension sleeve is provided with damping.

[0010] Preferably, the support rod has a threaded section on its side wall, and an adjusting nut is screwed onto the outside of the threaded section. The two ends of the shock-absorbing spring are fixedly connected to the extension sleeve and the adjusting nut, respectively.

[0011] Preferably, a limiting groove is provided on the side wall corresponding to the position of the support plate and the support rod, and a matching limiting pin is provided inside the limiting groove. The limiting pin is cross-shaped in general.

[0012] Preferably, a groove is provided on the side wall of the base, and the fixing strap is disposed in the groove, the fixing strap cooperating with the lower side wall of the extension sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In use, this invention utilizes the support rods and extension sleeves to form a support structure on the outside of the support rods, thereby ensuring the stability of the building structure. Simultaneously, based on the actual weight of the upper building structure, the length of the shock-absorbing springs can be adjusted by turning the adjusting nut, compressing or unfolding the springs to achieve a suitable elastic coefficient. This ensures effective shock absorption while maintaining support, thus guaranteeing the stability of the building structure. Furthermore, the unfolding of a set of support plates expands the overall support area of ​​the device, better supporting the building structure. The device is also foldable for easy storage, reducing its overall footprint and making it convenient for users to carry and move, thus expanding its overall range of applications.
