2. Description of the Related Art Conventionally, corrugated sheets have been frequently used as roof materials and wall materials for simple houses and garages. When replacing some or all of old or damaged corrugated sheets with new ones in buildings using corrugated sheets as roofing materials or wall materials, the pitch size of the existing corrugated sheets must be changed. Needless to say, it is necessary to measure and select a new corrugated sheet having the same pitch dimension.

If it becomes necessary to measure the pitch dimension of the corrugated sheet as described above, a claw 10 provided at one end of a main scale 101 using a caliper 100 as shown in FIG.
2 and a claw 104 provided at one end of the vernier 103
The pitch dimension was measured from the scales of the main scale 101 and the sub-scale 103 by contacting the center of a valley or a peak adjacent to each other.

[0004]

However, when the pitch dimension is measured using a caliper 100, the claws 102 and 104 of the main scale 101 and the sub-scale 103 are liable to slide left and right at the valleys or peaks of the corrugated plate 105. Since it is difficult to accurately position the tips of the claws 102 and 104 exactly in the middle of a valley or a mountain, there is a problem that the measurement operation is difficult and it is also difficult to accurately measure the pitch dimension. .
Therefore, it is not easy to quickly measure the pitch size of the existing old corrugated sheet and the new corrugated sheet in front of the constructor, prove that the pitch size of both is the same, and convince the constructor. In some cases, complaints were made later.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a corrugated sheet pitch gauge which can easily and accurately measure a corrugated sheet pitch dimension. .

[0006]

According to a first aspect of the present invention, a pitch gauge for a corrugated sheet is a pitch gauge whose main scale is slidably fitted inside a sub-scale. At one end of the main scale, a protruding portion having a tip shape substantially matching the shape of the valley portion of the corrugated sheet is projected downward, and the tip shape substantially matching the shape of the valley portion of the corrugated sheet also on the vernier scale. The projections provided with are projected downward.

In the pitch gauge for corrugated sheet having such a configuration, the protruding portion protruding from one end of the main scale and the protruding portion protruding from the vernier scale are fitted into the valleys of the corrugated sheet to form a scale of the main scale. And the pitch dimension of the corrugated sheet is measured from the scale of the vernier scale, but since the protruding part of the main scale and the protruding part of the vernier also have a tip shape that almost matches the shape of the valley of the corrugated sheet, When these protrusions are fitted into the valleys of the corrugated sheet, the protrusions are positioned just in the middle of the valleys without sliding left and right inside the valleys. Therefore, the measuring operation is facilitated, and the pitch dimension of the corrugated sheet can be measured accurately.

According to a second aspect of the present invention, there is provided a pitch gauge for a corrugated sheet, wherein the main scale is slidably inserted inside the vernier scale, and one end of the main scale has a corrugated sheet. A protruding portion having a tip shape substantially matching the shape of the crest is projected downward, and a protruding portion having a tip shape substantially matching the shape of the crest of the corrugated sheet is also projected downward on the vernier scale. It is characterized by having.

In the corrugated sheet pitch gauge having such a configuration, both the main scale protrusion and the sub-scale protrusion have a tip shape substantially matching the shape of the crest of the corrugated sheet. When placed on the crest of the plate, the protrusion is positioned exactly in the middle of the crest without sliding left and right on the crest. Therefore,
This pitch gauge for corrugated sheets is also easy to perform a measuring operation, and can accurately measure the pitch dimension of corrugated sheets.

The pitch gauge for a corrugated sheet according to claim 3 is the pitch gauge according to claim 1 or 2, wherein the vernier scale is formed in a sheath-shaped case having an opening window on the front surface. A protrusion is provided on the other end of the scale so as to protrude downward.

In the corrugated pitch gauge having such a configuration, when the main scale is drawn out from the vernier scale formed in the sheath-shaped case, the distance between the protruding portion of the main scale and the protruding portion of the vernier scale is equal to the length of the main scale. Since the value is nearly double, the total size of a large number of pitches of the corrugated sheet can be measured easily and accurately. By measuring the total dimension of a large number of pitches and dividing the measured value by the number of pitches to obtain the pitch dimension of the corrugated sheet, even if there is slight variation in the pitch dimension of the corrugated sheet, the average A precise pitch dimension can be obtained with high accuracy.

According to a fourth aspect of the present invention, in the pitch gauge for a corrugated sheet according to the first or second aspect, the sub-scale has a dovetail groove for inserting the main scale from the front surface thereof. A fixing screw formed on the sliding body and reaching the dovetail groove from the upper surface thereof is screwed therein.

The corrugated pitch gauge having such a configuration can measure from one pitch dimension to a total pitch dimension by sliding the vernier of the sliding body along the main scale. When the tip of the screw is pressed against the main scale in the dovetail groove by tightening, the sub-scale can be fixed at that position so as not to slide.
