Bridge Plastic Deformation Measuring device
Disclosed is a measuring device for plastic deformation on bridge deck pavement, which is to measure deformation of bridge deck pavement. The measuring device for plastic deformation on bridge deck pavement according to the present invention includes: a carriage having a center wheel on the lower surface; a length-variable support shaft of a telescopic structure of which the length is shortened or increased to both left and right sides in a first direction corresponding to a width direction of the carriage, wherein the length-variable support shaft is mounted on the carriage; a center gauge installed on the upper surface of the carriage in a second direction vertical to the first direction and having a measuring gradation formed on one side in the second direction; a first movable shaft connected to one side end of the support shaft to pitch in the second direction and having a first deformation amount measuring wheel at a lower end; a second movable shaft connected to the other side end of the support shaft positioned at an opposite side of the first movable shaft to pitch in the second direction and having a second deformation amount measuring wheel at the lower end; a first measuring bar bent at right angles from an upper end of the first movable shaft toward the center gauge; and a second measuring bar bent at right angles from the upper end of the second movable shaft toward the center gauge. The measuring device for plastic deformation on bridge deck pavement can rapidly and accurately measure plastic deformation generated on a road surface of a bridge structure without skilled professionals or expensive exclusive equipment.
교면 포장의 변형을 측정하기 위한 교면 포장 소성변형 측정기가 개시된다. 본 발명에 따른 교면 포장 소성변형 측정기는, 하면에 중심바퀴가 달린 이동대차와, 이동대차에 장착되며 이동대차의 폭 방향과 일치하는 제1 방향에 대해 좌우 양측으로 길이가 늘거나 줄어드는 텔레스코픽 구조의 길이 가변형 지지축과, 이동대차의 상면에 상기 제1 방향과 수직한 제2 방향으로 설치되며 일면에 상기 제2 방향으로 형성되는 계측눈금을 갖는 센터 게이지와, 지지축의 일측 말단에 제2 방향으로 요동 가능하게 결합되며 하단에 제1 변형량 측정바퀴가 달린 제1 가동축과, 제1 가동축 반대편에 위치한 지지축의 타측 말단에 제2 방향으로 요동 가능하게 결합되며 하단에 제2 변형량 측정바퀴가 달린 제2 가동축과, 제1 가동축의 상단에서 센터 게이지를 향하도록 직각으로 절곡되는 제1 계측바 및 제2 가동축의 상단에서 센터 게이지를 향하도록 직각으로 절곡되는 제2 계측바를 포함하는 것을 구성의 요지로 한다.
