Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a blocking structure for a damper part of a public building. Background Art
[0002] Dampers are increasingly used in the construction industry, particularly in public buildings such as hospitals and schools. Maintaining building safety and stability is crucial in earthquake-prone areas. Dampers dissipate vibration energy input into the building structure through the damping force they generate, thereby reducing structural vibration. This attenuates structural vibration and protects the main structure and components from damage, ensuring structural safety during strong earthquakes or wind-induced vibrations. Most dampers are installed within the shear walls of a building. After installation, the remaining cantilever walls must be sealed on both sides.
[0003] Currently, the common construction method is to seal both sides with masonry or install slatted walls before applying decorative finishes. For public buildings, dampers are sometimes installed close to rooms with water. Typically, one side of the cantilever wall houses the room with water, while the other side serves as a corridor. If masonry or slatted walls are used, the room with water will be exposed to humidity for extended periods, potentially affecting the damper's performance. Furthermore, if masonry is used to seal the corridor, it could easily be damaged during later maintenance. Utility Model Content
