BRIDGE DISPLACEMENT GAUGE USING TENSION STRING |
摘要 |
The present invention relates to a gauge installed at discrete positions of a girder (11) or a deck of a bridge to measure a displacement of the corresponding member, the gauge comprising a plurality of pulleys (30) respectively installed at both members at discrete positions, and a string (20) installed circularly over the pulleys and kept in a tense state by a winding part (51) with a built-in spring (53). The gauge measures a movement distance of the string (20) generated as a distance between the pulleys (30) decreases or increases. According to the present invention, a movement of the string (20) is significantly expanded as compared with an actual approach or separation distance between gauges installed on an upper structure of a bridge to be measured. As a result, an amplified measurement of a displacement of the structure is obtained and measuring accuracy may be remarkably improved. |
