Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural planning ruler for setting a schematic form of a building and an arrangement on a site in a building planning stage, and a method of planning a building using the ruler. More specifically, the present invention relates to a building plan ruler and a building planning method for setting the form and arrangement of a road side portion of a building in accordance with the regulations of so-called road oblique line restrictions.

[0002]

2. Description of the Related Art With respect to the form of a building, a numerical restriction rule according to the Building Standards Law and the like is applied to a number of items for each site where the building is built. Therefore, when trying to build a building on each site, first of all, in the initial planning stage, the number of floors and floor area of the building, the arrangement of the building in the site, the height of the protrusion, etc. This is checked according to the above-mentioned restriction rules while assuming the overall schematic form, and the work of setting a legal schematic form while repeating the correction based on the check is performed.

[0003] Such planning work is usually carried out by the planner on the basis of knowledge and experience concerning various regulations, each time taking a certain amount of time and effort. There is a fact that it is not easy to standardize and improve the efficiency of planning work because it is different.

[0004]

As one of the above-mentioned restrictions, there is a restriction of road diagonal lines. This provision,
The height of each part of the building is limited to a certain value according to the width of the front road in order to ensure the aesthetic appearance and the feeling of openness of the front road facing the site.

[0005] According to the Building Standard Law as of 1998, the height of each part of a building is determined according to the division of a predetermined area or district.
When the horizontal distance from the boundary on the opposite side of the front road is within a predetermined distance (20 to 35 m) or less, the horizontal distance from the relevant portion to the boundary on the opposite side of the front road is determined by
It must be less than or equal to a value obtained by multiplying a predetermined numerical value (1.25 or 1.5) determined for each division such as district (Article 56, Paragraph 1, Item 1 of the same law).

[0006] In other words, as shown in FIG. 5, as shown in FIG. 5, a building 1 to be built in a predetermined area or district is, in principle, moved from the boundary line AL on the opposite side of the front road R to the sky above the site. A slant line SL started with a slope of .25 / 1 or 1.5 / 1 (hereinafter, these are referred to as road slope line slope values).
(Hereinafter referred to as road diagonal lines).

In order to comply with this regulation, the main projecting portions 1a, 1b, 1b,
1c, the heights ha, hb, hc and the horizontal distances pa, pb, p to the boundary line AL on the opposite side of the front road R.
c, it is necessary to check each of them. If any of the protrusions protrudes above the road diagonal line SL, the height of the portion is reduced or the position is set to the road boundary line. A correction must be made to retreat from BL. In addition, such a check operation becomes particularly troublesome as the configuration of the upper part of the building 1 becomes more complicated. In addition, code | symbol CL shows a road center line and code | symbol GL shows a ground surface.

Further, for a building that has receded from the boundary of the front road, in the application of the above-mentioned provisions, the term “boundary on the opposite side of the front road” in item 1 of item 1 means
A relaxed rule is provided that "the line is located outside the boundary line on the opposite side of the front road by a distance corresponding to the retreat distance of the building" (Article 56, Paragraph 1, Item 2 of the same law).

According to this relaxation rule, as shown in FIG. 6, when the outermost wall on the road side of the building 1 retreats from the road boundary line BL, the front road R is widened by the retreat distance w to the opposite side. It is assumed that the road diagonal line SL is started from the widened outer line as a starting point.

However, when this relaxation rule is applied, the starting position of the road diagonal line SL is determined based on the retreat distance w of the building 1 from the road boundary line BL. The starting position of the road oblique line SL also changes each time. Therefore, building 1
There is a problem that the operation of checking the height hd and the horizontal distance pd from the starting position of the oblique road becomes more complicated for the main projection 1d.

Therefore, the present invention is intended to perform a check operation when applying the relaxation rule on the premise that a building is arranged at a certain position retreating from a road boundary in a building planning stage. By providing a convenient architectural planning ruler and a building planning method using it,
For example, with respect to a building whose form is standardized to some extent, such as a prefabricated house, the purpose is to allow anyone to easily and quickly set the form and arrangement of the building which does not violate the regulations on road diagonal lines.

In general, such a building is standardized in accordance with a common module, such as a basic structure, a pillar arrangement, a floor height, various building materials, various equipment units, and the like. The entire building is configured by appropriately combining design patterns prepared with the above variations. For this reason, a certain degree of design freedom is ensured, but the form of the roof, balcony and the like appearing in the outer shape of the building is limited to a certain range of patterns. Therefore, for each conceivable pattern form, the heights of the main protruding parts are quantified in advance and marked on a ruler, making it possible to perform planning work easily and quickly using the ruler. Become. That is, the present invention is a building plan ruler used for planning a building having such a standardized form.

Further, in the present invention, the main projecting portion is a portion formed so as to protrude outside or upward of a building and may interfere with a road oblique line.

Assuming that the building is disposed to be receded from the road boundary, the above-mentioned mitigation rules make the road diagonal from the position widened toward the front road by the retreat distance from the road boundary. Is launched. At this time, the position bisecting the road side wall position of the building and the starting point of the road diagonal line always coincides with the road center line. Therefore, on the basis of the road center line, it is possible to determine in advance the position where each of the main protruding portions of the building is at the very end of the road oblique line according to the height.

That is, the ruler for architectural planning of the present invention calculates the value obtained by dividing the height of each major projecting portion by the slope value of the road diagonal line.
