Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention is a vertical cross-sectional view in the field of construction. Concerning a ruler for drawing a drawing, which is convenient for printing and drawing.

[0002]

[Prior art]

  Generally, in the field of construction, what corresponds to an elevation sectional view is It is called a map. The scale of the kana diagram is 1/10 or 1/20 Is generally 1/25 or 1/30.

[0003]   In order to read the actual size from the drawing The actual size was calculated by multiplying the read scale number by the reciprocal of the scale. On the contrary, When making a drawing, the actual size was multiplied by the scale to write the length in the drawing.

[0004]   Conventionally, there are rulers with various scales, but one end is 0 Most of the rulers started.

[0005]

[Problems to be solved by the device]

  The purpose of the present invention is to read the actual size directly from the drawing as a ruler for Kana drawing only. It is easy to draw the scale length and scale on the drawing, and the ground surface (GL) You can read and write including the lower part, and it does not interfere with the application in the drafting machine. To provide a drawing ruler.

[0006]

[Means for Solving the Problems]

  The present inventor has determined that at least the longitudinal direction of the straight ruler is to be used as a ruler dedicated to the kana drawing. 1 / 10th, 1 / 20th, 25th / 30th, perpendicular to the longitudinal direction on one side 1 has a scale line of a scale selected from the scales of 1 and has an appropriate interval between the scale lines. The Arabic numeral scale corresponding to the actual size is placed at a distance from The position of 0 on the Arabic numeral scale is from the bottom of the straight edge to the long edge of the straight edge. If it is in the range of 1/50 to 1/4 of the distance in the direction, set the ground surface (GL) to 0. It can be applied to the whole part of the figure, and its thickness is 0.5m. It was found that it can be applied even on the drawing attached to the drafting machine by setting it to about m. did.

[0007]   The material of the straight edge ruler of the present invention is not particularly limited, and is generally used for office work and drafting. The used synthetic resin, metal, wood, etc. may be used. Also on the scale line and scale Regarding the notation, any conventional means such as printing or engraving may be used. The length and thickness of the line are not particularly limited. Do not apply to drawing machines If not, the thickness is not particularly limited.

[0008]   The number scale of the present invention is vertically long, and it is important to emphasize the vertical dimension. In many cases, the ruler is placed in the portrait orientation for reading, measurement, and drafting. It is preferable to write Arabic numerals in the direction perpendicular to the longitudinal direction of the ruler. It is preferable that the unit of the unit is a unit of mm, which is indicated by a kana diagram. Between the numbers The distance is not particularly limited, but is 50 as a notational number from the viewpoint of ease of use. A spacing of 0 mm is preferred.

[0009]   The straight edge of the straight edge of the present invention has a cutting surface called a taper with a part of the cross section being oblique. Alternatively, the taper may be omitted in the case of a thin ruler.

[0010]   The position of the 0 point of the straight edge ruler of the present invention is such that the kana diagram has a depth below the ground surface (GL). It is often displayed up to about 1000 mm, and in the case of RC building, about 2000 Since it is displayed up to mm, it corresponds to 1000 mm or 2000 mm in actual size from the lower end. It is preferable to set it at the position of the corresponding reduced scale length, and the number displayed above GL is It is necessary to change the length of the straightedge according to the height of the eaves of the building to be drafted, but the minimum is about 3 Numerical value display up to 000 mm, up to a scale length equivalent to about 10,000 mm Preferably. The length of the straightedge will be decided according to the reduction scale and the eaves height, From the point of handling the ruler, the maximum length of the ruler seems to be about 60 cm.

[0011]

[Example 1]   On a transparent acrylic plate (385 mm x 40 mm) with a thickness of 3 mm, the eyes as shown in FIG. The scale line and the numerical scale were silk-screen printed at a scale of 1/20. scale The side where the reed line was printed was taper-cut so that a part of its cross section was oblique. 0 The point is located at about 1 / 7.5th from the bottom of the ruler, and below GL is the maximum number scale. The maximum number scale above 1000 mm and GL was 6500 mm. 0 points The (GL) scale line is printed over the entire width direction of the ruler so that it can be easily identified. Created.

[0012]

Example 2   A scale line and a number scale are formed on a transparent acrylic plate having a thickness of 0.5 mm in the same manner as in Example 1. The ruler was printed to create a ruler. In this case, side taper cutting was not performed.

[0013]

Example 3   A transparent acrylic plate (385 mm x 40 mm) with a thickness of 3 mm is formed in the same manner as in Example 1. Silk screen with scale line and number scale as shown in 2 at a scale of 1/30 Printed. The side where the scale line is printed is tapered so that a part of the cross section becomes oblique. -I cut it. The scale line of 0 point is located at a position approximately one-third of the bottom of the ruler. Printed in the entire lateral direction of the GL, the maximum number of GL or less is 2000 mm, from GL The upper maximum number scale was set to 9000 mm.

[0014]

[Effect of device]

  By using the ruler of the present invention, it is possible to read the actual size from the kana diagram on the ground surface. It is possible to directly use the numerical scale including the following, and use the ruler of Example 2. This ensures that the drawing operation does not interfere with the arm operation and that the drawing is designed to match the actual dimensions. It is very convenient to write line lines, and it is possible to read actual size from drawings and drafting. This has made the work faster and more efficient.
