Description

[Detailed description of the invention] Industrial application field: The present invention is an architectural drawing that allows easy and accurate delineation of slope lines representing rectangular slopes and return slopes necessary for drawing architectural drawings. It concerns a ruler for creation.

Prior art and its problems: Architectural drawings are mostly composed of horizontal, vertical, and diagonal lines. Among these, the shakukan method slope (rectangular slope) is commonly used as a special case in the construction industry to display the slope angle represented by a diagonal line. This slope angle ranges from a 5 minute slope where the vertical dimension is 5 minutes to 1 shaku in the horizontal dimension to a 1 shaku slope where the vertical dimension is 1 shaku in the ratio of 1 shaku in the horizontal dimension. , slope angles in which the slope angle within this range is divided into five equal parts are often used.

To draw a diagonal line with this slope angle on paper,
For example, using a drawing machine, the horizontal scale of the drawing machine was adjusted to the slope angle to be drawn, and the horizontal scale was aligned with the reference point on the drawing to draw diagonal lines. However, the drawing to be drawn has many places with different slope angles, and the angle of the horizontal scale must be adjusted each time, which is complicated and inefficient. In addition, when creating a drawing, it is necessary to create a drawing with a diagonal line at a certain slope and exact slope angle, and there is a limit to finely adjusting the horizontal scale angle to that angle, making it impossible to accurately adjust the angle. The dot was hot.

In order to solve these problems, the present invention is designed to easily and accurately draw diagonal lines with the required slope angle necessary for drawing, which will help improve the efficiency of drawing. The purpose is to provide a ruler for creating architectural drawings.

Means for Solving the Problems: The present invention to achieve the above-mentioned object is to provide a rigid thin plate material of a desired shape with a base of a constant size, and a plurality of rigid thin plates having the same reference point provided at the end of the base. A ruler for creating architectural drawings, characterized in that inclined holes are bored in a radial manner, and each inclined hole has two radial inclined sides whose angle increases at the same ratio from the bottom side. It is.

Function: The ruler for creating architectural drawings of the present invention configured as described above has its base or vertical side aligned with the upper side of a horizontal ruler such as a manual drafting machine, so that the inclination angle required for drawing can be adjusted. Select a hole and place it in the desired position.
By drawing a line along the inclined sides, a desired inclined line can be accurately drawn. Also, if you use the vertical side as a reference instead of the bottom side, by first drawing a line along the same oblique side as the selected oblique side of the required inclined hole using the bottom side as a reference, you can It is also suitable for creating architectural drawings, etc. as it allows you to easily draw diagonal lines at right angles.

Embodiment: Hereinafter, one embodiment of the present invention will be described in detail based on the drawings. As shown in Figure 1, a hard thin plate material (such as a transparent synthetic resin plate) is used, and the horizontal dimension is 1 and the vertical dimension is 1 with an acute angle from one end of the base 2 to the base 2 of a constant dimension. An inclined side 3 having a slope angle as a percentage, and a vertical side 4 extending vertically from the other end of the base 2 are provided. The corner formed by the inclined side 3 and the vertical side 4 is cut parallel to the base 2, and the ruler 1 has a trapezoidal outline including a right angle. A reference hole 6 indicating a base point is bored at a suitable location in an acute corner 5 of the ruler 1, and a margin 7 is provided inside the vertical side 4. This ruler 1 has a horizontal dimension of 1 in terms of the slope of the slope with the reference hole 6 as the base point near the inclined side 3.
An upper oblique side 11 of the slope angle where the vertical dimension is at the ratio of n dimension to 5 minutes from the reference hole 6, and a lower oblique side 12 of the slope angle where the vertical dimension is at the ratio of n dimension to the horizontal dimension of 1 shaku from the reference hole 6. A slanted hole 10 is drilled therein. n is an integer. For example, if n is 9, the upper hypotenuse of the slope angle is the ratio of 9 suns and 5 parts of the vertical dimension to 1 shaku in the horizontal dimension, and 9 suns in the vertical dimension to 1 shaku in the horizontal dimension. It is the lower hypotenuse of the slope angle as a percentage of . In addition, near the bottom side 2, there is a lower side 13 at the same level as the reference hole 6, and a horizontal dimension 13 from the reference hole 6.
An inclined hole 10' having an upper hypotenuse side 11 with a slope angle of 5 minutes perpendicular to the scale is bored, and between the inclined hole 10 and the inclined hole 10' there is a lowermost slope. Starting from the hole 10', inclined holes 10 are radially drilled in which the upper and lower hypotenuses 11 and 12 have slope angles such that the vertical dimension increases at a ratio of 5 minutes to 1 shaku in the horizontal dimension when the base point is the same. . In this way, the ruler for creating architectural drawings of the present invention is obtained.

In addition, the ruler for creating architectural drawings as a separate example is the second one.
As shown in the figure, the horizontal dimension with the same base point from the narrow horizontal hole 21 with a slope angle of 0 degrees from the reference hole 6 from the base 2 side of the ruler 20 with the same outline is 1
The narrow inclined holes 22 may be sequentially drilled radially at a gradient angle of every 5 minutes up to a gradient angle in which the vertical dimension is a ratio of n dimension to 5 minutes.

In the margin part 7 of the ruler 1, slope angle values 14 are written in a scale-through slope at the end positions of the upper hypotenuse 11, lower hypotenuse 12, and lower side 13 of each inclined hole 10, respectively. Also, in the margin part 7 of the ruler 10 of the separate embodiment, slope angle numerical values 14 are written in a scale-through slope at the end positions of each of the narrow inclined holes 22 and the narrow horizontal holes 21. Furthermore, scales 15 are marked near the inclined sides 3 and bottom sides 2 of the rulers 1 and 20, and one and both sides of the peripheral edges of the rulers 1 and 20 and the inner edges of each hole are chamfered, or the cross-sectional shape of the edges is It is engraved on a horizontally convex crosspiece. Further, the degree of the angle corresponding to the numerical value 14 may be written next to the numerical value 14 written in the margin 7, which is convenient as a quick reference table for the slope of the shank-kan method.

When using this ruler, as shown in Figure 3, use the horizontal scale 31 of the drawing machine 30 (the angle of this horizontal scale is 0 degrees and is aligned with the reference line on the drawing).
Simply align the bottom edge 2 of the ruler with the top edge, align the oblique sides of the required inclined holes 10 and 10' with the reference point on the drawing, and draw a line along this oblique side to easily draw a diagonal line with an accurate slope. be able to. or,
When drawing a return slope (a diagonal line perpendicular to the slope diagonal line) using this ruler, rotate the ruler 90 degrees and align the vertical side 4 with the top of the horizontal scale 31, using the same hypotenuse used for the above-mentioned line drawing point. By drawing a line along , you can draw a diagonal line for the return slope. When drawing diagonal lines for slopes and reverse slopes on the opposite side of the drawing, the ruler can be used by turning it over vertically. This ruler can be used without the drawing machine 30, for example, the horizontal upper end of a T ruler (not shown),
Alternatively, the base 2 of the ruler may be aligned with the reference line on the drawing, and the line may be drawn in the same manner as with a ruler.

Furthermore, since this ruler is made of a transparent plate material, the numerical value indicating the slope angle can be seen through even if the ruler is used upside down without any inconvenience. In addition, by chamfering, when drawing lines using ink or ink, the ink or the like does not bleed onto the back side of the ruler and the drawing is wasted, and the round hole 8 drilled in the acute corner 5 of the ruler is prevented.
It is also convenient when cleaning up if you hang it on a locking metal fitting or the like.

In addition, it is not necessary to start from the bottom side with the slope angle of the adjustable side of the slanted hole and narrow slanted hole of the ruler set to 0 degrees, but you may start from any angle, and the slope angle of the slanted hole and narrow slanted hole It may be perforated at any angle. Furthermore, it goes without saying that a right-angled triangle or the like having an appropriate angle may be formed at an appropriate position on the ruler, and these are included within the technical scope of the present invention.

Effects of the invention: The ruler for creating architectural drawings of the present invention covers all inclined holes having the slope angle necessary for creating architectural drawings, and when drawing, it is possible to draw along the oblique side of the required inclined hole. All you had to do was draw the lines, making it easy to create accurate drawings. To draw a return slope, simply rotate this ruler 90 degrees and draw the line in the same manner as above, and you can use a single ruler to draw the rectangular slope and the return slope. In addition, the time required to draw lines for rectangular slopes and return slopes, which was conventionally done only with a drawing machine, can be significantly shortened, and it is greatly useful for improving the efficiency of drawing work, and the structure is simple. Therefore, it has many advantages such as being able to be provided at low cost.
