BRAKING DEVICE AND BASE ISOLATION STRUCTURE OF BUILDING

Title:

BRAKING DEVICE AND BASE ISOLATION STRUCTURE OF BUILDING

Document Type and Number:

Japanese Patent JP2023102614

Kind Code:

A

Abstract:

To provide a braking device which is excellent in energy absorption performance, can be repeatedly used, and can shorten a length in an action direction of external force.SOLUTION: A braking device 1 for absorbing energy generated by external force includes: a pair of sliders 2, 2 moving in an action direction of the external force; a spring 3 interposed between the pair of sliders and having an extension/contraction direction almost orthogonal to the action direction; a core material 4 inserted into a hollow 3a of the spring and allowing the pair of sliders to move; and a body 5 for fixing both ends of the core material and controlling a moving direction of the slider. When the external force is applied to the slider and the slider is moved to the action direction, a gap between the pair of sliders is narrowed accordingly, and the spring is contracted, and at the same time, energy absorption by sliding is performed between the body and the slider and between the spring and the slider.SELECTED DRAWING: Figure 1
