Problems solved by technology

In dampers using lead, steel rods, etc., there is a risk of environmental contamination due to lead, and both ends of the lead, steel rods, etc. need to be securely clamped to a pair of mutually moving parts
[0005] Meanwhile, in the damping using sliding parts, there is a possibility that the performance may be deteriorated due to wear of the sliding parts
In addition, the sliding layer of the slider may peel off, which may also lead to deterioration of performance

Abstract

A friction damper (1) comprising: a base body (2); a support (4) fixed on an elongated member (35) of the base body (2) and having a through hole (3); extending through the support (4) The through hole (3) and the rod (7) movable in the axial direction (X) relative to the support; has the main body inserted in the support (4) and the rod (7) in the through hole (3) of the support (4) The friction member (9) of the hollow cylindrical part (8) between the parts (85), which is immobilized relative to the relative movement of the rod (7) in the axial direction (X) with respect to the base body (2); and Tensioning means arranged on the support (4) to tension the hollow cylindrical part (8) of the friction member (9) on the main part (85) of the rod (7).

Description

[0001] The applicant of this application is Oiles Industrial Co., Ltd., the application number is 03802179.X (the international application number is PCT / JP03 / 00256), the international application date is January 15, 2003, and the title is "friction damper" divisional application. technical field [0002] The present invention relates to a damper installed between a pair of mutually moving parts and capable of damping the movement by frictionally absorbing the moving energy between the parts as quickly as possible. More specifically, the present invention relates to a frictional damper capable of moving as rapidly as possible by absorbing the energy of movement occurring in buildings such as office buildings, multi-family buildings, outbuildings, bridges, etc. due to earthquakes or the like. Damped movement. Background technique [0003] As dampers for quickly damping lateral shaking in construction such as due to earthquakes or the like, those using viscous materials for v...
