簡単に測定することが困難であつた。[Prior Art] Currently, as described in the Paving Guidelines, flat rulers and profile meters are used to measure the unevenness of the road surface. Although accuracy is good if a large profile meter is used, it is difficult to handle. In addition, although the flatness ruler is relatively simple, the positional relationship of measurement points is not clear, and it is necessary to take measures such as stopping traffic during measurement, making it difficult to easily measure at any time and place. It was hot.

［考案が解決しようとする課題］本考案の課題は、前記の難点を解消し、尚かつ

貫通させた折畳式わだち計。 Consists of a rod-shaped scale, a pair of left and right horizontal scales located perpendicular to the rod-shaped scale, and a pair of tension rods that stabilize both horizontal scales, and the horizontal scale receives the lower end of the rod-shaped scale. The lower end of the tension rod is pivoted to the open end of the horizontal scale using a pin, the upper end is pivotally attached to the stop member using a pin, and the rod-like scale is attached to the receiving member and the contact member. A folding type rut gauge that penetrates through the insertion hole formed in the piece.

平行に折畳まれる。[Example] In the figure, 1 is a rod-like scale, 2 and 2' are horizontal scales, and 3 and 3' are tension rods. horizontal scale 2,
2' is pivotally connected to the connecting piece 4 which supports the lower end of the rod scale 1 by means of pins 5 and 5', and is positioned at right angles to the left and right sides of the rod scale 1 standing there. Tension rod 3,
The lower end is pivotally connected to the receiving member 8 of 3' with pins 9, 9', and the lower end is pivotally connected to the open end of the horizontal scale 2, 2' with pins 6, 6'. Further, the rod-shaped scale 1 penetrates through an insertion hole 7 formed in the receiving member 8 and the connecting piece 4. When in use, the tension rod and horizontal scale protrude left and right from the rod-like scale 1 as shown in Figure 1, forming a triangular shape, and when not in use, each component is folded parallel to each other as shown in Figure 4. Folded.

［考案の効果］本考案によれば、わだちの深さを正確、容易に
