  • Patent number: 9689173
    Abstract: A construction component provided with a vibration damper includes a quadrangular frame in a front elevational view including four structural members, and the vibration damper includes: a vibration damping tool provided inside the frame; and four braces radially extending from the vibration damping tool and connected to the frame. The vibration energy deforming the frame is transmitted via the braces to the vibration damping tool to plastically deform the vibration damping tool, thereby absorbing the vibration energy in the vibration damping tool to damp vibration. The construction component further includes a bridging member configured to bridge a gap between two facing members of the four structural members. A part of the bridging member configured to overlap with the vibration damping tool in the front elevational view is defined as an interference avoidance portion in which interference between the part and the vibration damping tool is avoided.
