2. Description of the Related Art For a height of 5 m or more of a building, the first-class residential area, the second-class residential area, or the first-class altitude area, the second-class altitude area, etc. are classified according to the law. The retreat distance from the boundary line on the north side adjacent land of the building (hereinafter, the retreat distance from the boundary line on the north side adjacent land of the building is referred to as a north diagonal line) is determined. In detail, in the first-class residential area, 5m + slope 1.25 / 1, in the second-class residential area, 10m + 1.25 / 1, in the first-class advanced area, 5m + 0.6 / 1, second class. In the altitude area, 5m + 1.25 / 1 and 15m + 0.6 / 1
Has become. These values are the rising and the gradient from the reference point on the borderline of the adjacent land orthogonal to true north.
In most cases, the borderline between adjacent buildings in a real building is not orthogonal to true north. Therefore, when designing a building,
Set the receding distance from the borderline on the north side of the lower part of the building,
It is necessary to calculate corresponding to the deviation angle of the north side adjacent land boundary line from the right north orthogonal direction and the eave height, and to determine the north side diagonal line of the height part of 5 m or more based on this value, each time,
The receding distance is calculated by a trigonometric function or a chart.

[0003]

However, the conventional calculation of the retreat distance has a complicated problem. This is a simple calculation itself, but it is necessary to perform trigonometric calculation or diagram calculation every time the building is designed, and many calculations are required at the time of determining the eaves height in the initial stage of planning. In some cases, it is troublesome and time-consuming. An object of the present invention is to provide an auxiliary ruler for the diagonal line on the north side, which can easily and quickly obtain the value of the retreat distance from the boundary line on the north side of the lower part of the building when determining the diagonal line on the north side of the building. .

[0004]

The diagonal auxiliary ruler on the north side according to the present invention has an eaves height scale of the target building on one axis of the orthogonal biaxial diagram printed on the sheet surface and the other axis on the other axis. The scale of the retreat distance from the borderline of the adjacent land on the north side of the building site is carved at the same ratio as the scale of the eaves height, and the orthogonal 2
It is constructed by engraving radial angle scales of 0 to 90 on the orthogonal biaxial chart centering on the starting point where the axes intersect.

[0005]

When the eaves height scale of a building is engraved on one axis of the orthogonal two-axis chart and the retreat distance scale from the north side adjacent land boundary line of the building is engraved on the other axis, the two vertical axes are It is a chart of the relationship showing the retreat distance corresponding to the eaves height dimension when the boundary line on the north side of the building faces the true north direction. This orthogonal 2
If you connect the two orthogonal axes and the angle scale by radially engraving the angle scale of 0 to 90 ° around the intersection starting point of the two orthogonal axes between the axes, the north side of the north side adjacent land boundary line at each eave height The receding distance according to the deviation angle from the orthogonal direction is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view showing an embodiment of a north side oblique auxiliary ruler of the present invention. In the figure, 1 is a diagonal ruler on the north side, 2
Is a seat surface, 3 is an orthogonal biaxial chart, 31 is an orthogonal biaxial chart 3
Eaves height scale, 32 is also the retreat distance scale, 33
Are also starting points, and 34 is also an angle scale. As shown in FIG. 1, the diagonal auxiliary ruler 1 on the north side of this embodiment uses an orthogonal biaxial diagram 3 printed on a white hard plastic sheet surface 2. In this embodiment, the vertical axis is adopted as one axis of the orthogonal biaxial chart 3 and the eaves height scale 31 of the target building is used as the vertical axis.
Carve. The eaves height scale 31 has a vertical axis lower end of 5 m,
Scale lines every 0.5 m were carved up to 10 m at intervals of 1 cm per scale.

On the horizontal axis, which is the other axis of the orthogonal biaxial diagram 3, is set a scale 32 of the retreat distance from the boundary line of the adjacent land on the north side of the building site. The retreat distance scale 32 also has the same ratio as the eaves height scale 31, that is, the scale line is set at intervals of 0.5 cm every 1 cm, and the left end of the horizontal axis is 0 m, 5 m.
Chopped up. And the starting point portion 3 where the two orthogonal axes intersect
3, that is, centering on the intersection of the lower end of the vertical axis and the left end of the horizontal axis, angular scales 34 are radially engraved on the orthogonal biaxial diagram 3. The angle scale 34 is a radial angle scale in which the vertical axis of the starting point portion 33 is 0 ° and the horizontal axis of the same starting point portion 33 is 90 °, and the horizontal axis of the starting point portion 33 is divided at equal intervals of 15 °. In the present embodiment, in order to make it easier to understand the relationship between the eave height and the retreat distance for each 1 m on the orthogonal biaxial chart 3, an arc shape is formed by connecting every 1 m of the eave height and every 1 m of the retreat distance in an arc shape. A curve 35 is provided centering on the starting point portion 33. Therefore, it is easy to obtain the angular position between the angle scales 34 based on the position of the arc-shaped curve 35.

[0008] North side oblique line auxiliary ruler 1 constructed as described above
Aligns the eaves height dimension of the target building with the eaves height dimension scale 31, and moves the scale position horizontally to the right. On the other hand, the deviation angle of the boundary line of the north side of this building from the right north orthogonal direction is set in accordance with the angle scale 34, and the vertical direction is vertically moved downward from the intersection of this angle scale position and the horizontally moved scale position. The intersection of the line with the retreat distance scale 32 is the retreat distance of the lower part of the building from the north side adjacent land boundary line in this case. In this way, even on the north side adjacent land boundary line at an angle deviated from the true north orthogonal direction, it corresponds to the eaves height of the building, and the retreat distance according to the deviation angle of the north side adjacent land boundary line is extremely simple,
Quickly requested and very convenient. The ruler is a chart printed on a thin sheet surface, which is easy to carry and can be prepared at low cost.

The north side auxiliary ruler of the present invention can be modified in various ways other than the above embodiment. For example, the eaves height dimension scale and the retreat distance dimension scale of the orthogonal biaxial diagram can be similarly configured by switching them from vertical to horizontal. Further, it is possible to easily make reading easy by limiting each graduation range and forming a large interval graduation into a plurality of sheets. Alternatively, the color of each scale can be changed to make it easier to read.
