Abstract

Cette invention concerne un dispositif permettant de mesurer une différence de largeur entre des stries, des fractures et des espaces vides dans des objets utilisés pour la construction, lequel dispositif consiste en une plaque graduée supérieure (2) et une plaque graduée inférieure (1), lesquelles plaques sont pourvues d'orifices de fixation (3, 4) permettant une fixation solide de la plaque supérieure (2) et de la plaque inférieure (1) sur l'élément examiné, de telle sorte que la plaque inférieure (1) et la plaque supérieure (2) sont fixées sur l'élément sur les côtés opposés à la strie, à la fracture ou à l'espace vide. Ces plaques coulissent partiellement l'une sur l'autre. La plaque supérieure (2) est située sur la plaque inférieure (1) de manière à permettre un déplacement réciproque.
