Edge Distance Measuring Device for Bridge Safety Inspection
The present invention relates to an edge distance measuring device for a bridge safety diagnosis, which comprises: a holder fixing plate (30) having a predetermined thickness; a shaft (31) which is formed at the holder fixing plate (30); a male screw unit (32) which is formed at the shaft (31); a left side height adjustment arm (40) and a right side height adjustment arm (50) which cross with each other in an inverted V shape; a horizontal bar (60) which is supported with the upper surface (21) of a bridge lower structure (20), and is installed at the left side height adjustment arm (40) and the right side height adjustment arm (50); a front i-ring (41) which is formed at the upper end of the left side height adjustment arm (40); a rear i-ring (51) which is formed at the upper end of the right side height adjustment arm (50); a ring spacer (70) which is rotated along with the rear i-ring (51); a plunger screw hole (71) which is formed at the ring spacer (70); a plunger bolt (74) which is installed at the plunger screw hole (71); a steel ball (73) which receives elastic force in a protruding direction toward the front i-ring (41) by a spring (72) built in the plunger bolt (74); a stopping groove (41g) which determines the location of the steel ball (73); a pressure adjustment nut (80) which is coupled to the male screw unit (32); a spring storage chamber (81) which is formed at the pressure adjustment nut (80); a friction spring (82) which resists between the rear i-ring (51) and the pressure adjustment nut (80); and a laser holder (90) which holds the laser distance measuring device (22). Therefore, the edge distance of a bridge may be conveniently and precisely measured.
