Damping top, damping rod, and damping device using same

A damping device comprising:

• first and second connective members so connected with each other as to be relatively displaceable;
• said first connective member further comprising an inner tube formed with a guide screw in its connecting side, and a disk-shaped rotational body engaged with said guide screw and having a sufficiently larger diameter than said inner tube and being attached thereto rotatably and slidably on the basis of a relative displacement from the guide screw;
• said second connective member further comprising an outer tube, and a cylindrically shaped casing formed in its connecting side for accommodating said rotational body,
• said damping device, comprising at least one selected from the group consisting of a viscous material and a viscoelastic material is filled for damping in a gap defined between an inner wall of said cylindrically shaped casing and said rotational body.

A damping device comprising:

• first and second connective members so connected with each other as to be relatively displaceable;
• said first connective member further comprising a first rod formed with a guide screw at least in its connecting side, a guide nut engaged with said guide screw and axially supported so as to rotate and slide on said guide screw on the basis of a relative displacement from the guide screw, and a cylindrically shaped rotational body having a sufficiently larger diameter than said first rod and having a sufficiently larger length in axial direction than a diameter itself and further being rotatably and slidably attached thereto through said guide nut;
• said second connective member further comprising a cylindrically shaped casing formed in its connecting side for accommodating said cylindrically shaped rotational body and said guide nut,
• said damping device comprising a viscous material and a viscoelastic material is filled for damping in a gap defined between an inner wall of said cylindrically shaped casing and said cylindrically shaped rotational body.

A method of using a damping device, wherein said damping device comprises first and second connective members so connected with each other as to be relatively displaceable;

• said first connective member further comprising a first rod formed with a guide screw in its connecting side, a guide nut engaged with said guide screw and axially supported so as to rotate and slide on said guide screw on the basis of a relative displacement from the guide screw, and a disk-shaped rotational body having a sufficiently larger diameter than said first rod and being rotatably and slidably attached thereto through said guide nut;
• said second connective member further comprising a second rod, and a cylindrically shaped casing formed in its connecting side for accommodating said rotational body and said guide nut,
• said damping device further comprising at least one selected from the group consisting of a viscous material and a viscoelastic material is filled for damping a gap defined between an inner wall of said cylindrically shaped casing and said rotational body, the method comprising
• providing said damping device between diagonally opposite comers of a frame structure in a building construction, so that said damping device is allowed to be compressed and tensed.
