Title:
DISPLACEMENT MEASURING INSTRUMENT OF STRUCTURE
Document Type and Number:
Japanese Patent JP2023178156
Kind Code:
A
Abstract:
To solve the problem in which, in a displacement gage where an intermediate part of a filament body stretched between immovable points is provided to a measuring target structure, when measuring a displacement from a prescribed part of the filament body, since a stretching distance of the filament body often reaches dozens of meters, the filament body is applied with adequate tension (e.g. suspending a weight) in consideration of continuing to oscillate the filament body with non-quantitative all the time due to meteorological condition such as wind, however, when mounting a measuring instrument at a site, coupling a weight of 200 N to the filament body by a manual operation and fixing the weight onto a prescribed position are extremely difficult, and, since extension of the filament body is generated for the couple of days just after mounting it, recoupling operation of the weight is necessary to be conducted repeatedly.SOLUTION: A displacement measuring instrument comprises: a filament body suspended between one end part connected to a weight provided at one immovable point and the other end part connected to a rewinder provided at the other immovable point in between two points as immovable points; and a displacement gage provided on a structure as a measuring target positioned at an intermediate part of the immovable points and measuring a displacement from the filament body.SELECTED DRAWING: Figure 2
