Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for designing a pitched roof, which can be easily designed even by a non-specialized designer and can be operated by a personal computer (hereinafter referred to as a personal computer). Regarding the method.

[0002]

BACKGROUND ART Conventionally, a roof shape has a great influence on the appearance of a building, especially in a detached house, etc., and according to a customer's request, regardless of the shape of the building body such as a gable roof or a parquet roof. Since it can be designed, it was necessary to have sufficient discussions with the customer.

[0003]

Conventionally, however, a roof has been designed by a professional designer based on his experience so far. For example, when a sales person is having a meeting with a customer, the roof shape is requested by the customer. However, there is a problem that it is necessary to return it to the designer once to make a design change, and it is not possible to quickly respond.

[0004] In recent years, CAD has been used for building design, but there are various types of roofs such as gables, parquets, or a combination of these. Since the designs are different due to differences such as gradients and gradients, there are a lot of types of data to be processed, there is a problem that it can be realized only in a large-scale system, and the processing takes time.

An object of the present invention is to easily design a roof,
It is to provide a method of designing a pitched roof that can be operated by a small system such as a personal computer.

[0006]

According to the method of designing a pitched roof of the present invention, at least one rectangular area whose short side is located outside the roof installation area is provided in the entire roof installation area where the pitched roof is provided. It is characterized in that after setting and designing the roof of the rectangular area having the maximum short side dimension among these rectangular areas, the roof of the rectangular area having the next shortest side dimension is sequentially designed. Here, when there is one rectangular area, only the roof of that rectangular area needs to be designed. In addition, the roof installation area means a portion where a roof is installed in a building.

In this case, the short side dimension of the rectangular area may be calculated by multiplying the horizontal length of the short side of the rectangular area by a slope coefficient according to the roof slope, or a sloped roof. If all of the gradients are the same, the short side dimension may be used as it is.

As a concrete design of the pitched roof,
After designing a ridge on the short side of the rectangular area with the shortest dimension and connecting the vertices of this ridge to design a large ridge, the largest of the rectangular areas with the next shorter shortest dimension is selected. Design a ridge on the short side that is not included in the rectangular area, design a large ridge from the apex of this ridge toward the short side of the other end, and if this large ridge reaches the slope roof already designed It is preferable to design the ridge from that part.

Furthermore, when designing a dwelling from a large building that has reached the already designed pitched roof, the dribble and the short building designed on the short side not included in the rectangular area where the pitched roof has already been designed. Translate the triangle consisting of sides to the other short side, design the large ridge by the trajectory of the vertices of the triangle, and when the triangle reaches the already designed slope roof surface, within the triangular ridge, It is preferable that the part of the pitched roof that already overlaps with the drip ridge is erased, and the part that does not overlap is newly designed as a drip ridge.

Further, the large building of the ridged part of the pitched roof designed in the rectangular area is extended to a position above the short side of the rectangular area, and the part of the ridged building which has been set as a small building has its ridge line erased. It may be possible to newly set a ridge line of the part that was erased to connect with another roof surface and change the design from the gathering ridge to the gable. In addition, the gable part of the sloped roof designed in the rectangular area is shortened and moved from the short side of the rectangular area, and the part that was set as the gable's ridge and other roof surfaces Erase each ridge line of the connecting part, set a new ridge line connecting both ends of the short side and the end of the large ridge, and remove the ridge line of the part that overlaps the already set ridge line. You may erase and change the design from a gable to a parish.

[0011]

In the present invention, the roof installation area is first divided into one or more rectangular areas. This rectangular area allows at least one short side of each rectangular area to be located on the outer periphery of the roof installation area, and allows a part of each area to overlap, and further, all parts of the roof installation area have at least 1 part. Set to be included in one rectangular area. Then, of these rectangular areas, the rectangular area having the shortest dimension is selected, that is, the rectangular area in which the height position of the large ridge is the highest is selected, and the rectangular ridge ( Design a "Sumi wing" for the gathering wing and a "flat ridge" for the gable), and set a large ridge between the peaks of each ridge.

Next, if there are other rectangular areas, the rectangular area having the largest short-side dimension is selected from them, and the pitched roof is designed. At this time, if the selected rectangular area already has a portion overlapping the rectangular area for which the pitched roof has been designed, a ridge is designed on the short side other than the overlapping portion.
Then, when the ridges are set on the short sides on both sides of the rectangular area, a large ridge is designed between the apexes of each ridge. Also,
If a ridge is set on only one of the short sides, the large ridge should be extended from the top of the ridge. Then, when the large building reaches the sloped roof surface that has already been designed, a descent building (for example, "valley building") is set from the intersection. A sloping roof is designed by performing the above processing by a drawing or design computer.

At this time, since the sloping roof is designed for each rectangular area, the individual roof design is simplified and carried out easily. Also, when there are multiple rectangular areas, the pitched roof is designed from the rectangular area with the shortest side dimension being the largest, that is, because the height of the main building is designed from a high pitched roof,
Connections with other pitched roofs, where the height of the large building is low, are also designed one after another to enable efficient design work.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. 1 (A) to 1 (H) are plan views of the roof 1 of the first embodiment of the present invention, showing a design procedure for the parquet roof, based on which the design of the first embodiment is designed. The method will be described. First, as shown in FIG. 1 (A), at least one (two in FIG. 1) rectangular area is provided in a roof installation area 2 where a roof is installed in a building so as to cover all of the roof installation area 2. Set 11 and 12. The rectangular areas 11 and 12 are as rectangular as possible.
So that the number of 2's is reduced and each rectangular area 11, 12 is
The short sides 11A, 11B and 12A, 12B are set to be the outer periphery of the roof installation area 2.

Next, as shown in FIG. 1B, the short sides 11A, 11B, 12A and 12B of the rectangular areas 11 and 12 are detected and their lengths are measured. In addition, as shown in FIG. 1C, the short side 1 of the portion where the rectangular regions 11 and 12 overlap each other.
1B and 12B are set so that the short side 11B of the rectangular area 11 having a large short side dimension is left.

Next, as shown in FIG. 1D, the short sides 11A and 11B of the rectangular area 11 and the short side 1 of the rectangular area 12
Set the ridge from each end of 2A. In the present embodiment, since the roof 1 of the gathering ridge is used, the ridge 13, which is a ridge,
14 are set respectively. Specifically, if the roof slopes are the same, set two squares with half the short sides 11A, 11B, 12A on each short side, and draw the diagonals of these squares. Buildings 13 and 14 are set up.

Then, as shown in FIG. 1E, the large ridge 15 is set by connecting the apexes (intersections) of the corner ridges 13 on the respective short sides 11A and 11B. Next, as shown in FIG. 1F, the large ridge 16 is set from the corner ridge 14 set on the short side 12A of the rectangular area 12 toward the other short side 12B of the rectangular area 12. In the present embodiment, the large ridge 16 is set by translating the triangle abc constituted by the corner ridge 14 and the short side 12A by the protrusion dimension L of the rectangular region 12 and leaving the locus of the apex b portion.

Then, as shown in FIG. 1 (G), in the triangle a'b'c 'after translation, the corner ridge 13
Since the line segment b'c 'that overlaps with is in the same plane,
As shown in (H), the line is erased, and the non-overlapping line segment a'c 'draws the line (valley 17). The above-mentioned procedure is designed automatically by using a personal computer, or by a person in charge, to design a parquet roof (slope roof) 1. Although the roof 1 is shown as a plan view in FIG. 1, particularly when a personal computer is used, since it is processed by three-dimensional data including height data, as shown in FIG. The figure can also be displayed.

FIG. 3 shows a second embodiment of the invention for designing a gable roof 20. In FIG. 2, (A)
Since (C) is the same as that of the first embodiment, the same reference numerals are given and the description thereof is omitted. Then, as shown in FIG. 3D, a blind building is set on each of the short sides 11A and 11B of the rectangular area 11 and the short side 12A of the rectangular area 12. In this embodiment, as shown in FIG. 4, the short sides 11A and 11B are gabled, so that the flat ridge 21 (in FIG. 3, the short sides 11A and 1B).
1B) and the short side 12A has a corner ridge 14. Then, as shown in FIG. 3E, the ridges (intersections) of the flat ridges 21 on the short sides 11A and 11B are connected to each other to set the large ridge 15.

Next, as shown in FIG.
A large ridge 16 is set from the corner ridge 14 set to A toward the other short side 12B of the rectangular area 12. And big building 1
6 extends in parallel, and the sloped roof surface 20A of the gable roof 20
As shown in FIGS. 2 (G) and 2 (H), the valley ridge 17 is set from the intersection that has reached. Through the above procedure, the roof 20 of the gable (partial ridge) is designed. Also in this case,
Designed either automatically using a personal computer or by a person in charge to draw a figure, and can display side and perspective views.

According to the first and second embodiments, when designing a sloping roof such as a parquet roof 1 or a gable roof 20, a plurality of rectangular areas 1 are provided in the roof installation area 2.
1 and 12 are set, and rectangular areas 11 and 1 with large short side dimensions
Since the roofs 1 and 20 are designed in order from 2, even if the roof installation area 2 has a complicated shape, the design of the sloping roof is simplified in each of the rectangular areas 11 and 12, so it is easy to design. You can Therefore, even if you are not an expert in roof design, you can easily design a pitched roof easily.
We can quickly respond to customer requests.

Since the design procedure is simplified,
It can be operated with a small system such as a personal computer, and the pitched roof design can be automated. Therefore, it can be operated even with a portable system such as a laptop computer, and for example, a person in charge can go to the customer's site and present various pitched roofs for a meeting and meet the customer's request quickly and efficiently. You can have a meeting according to your image.

Further, since the rectangular area 11 having a large short-side dimension, that is, the sloped roof having the higher height of the large building 15 is designed, even when the rectangular area 12 is provided with a roof having a different height, Since the connecting part of each roof can be easily designed by simple work such as setting the valley ridge 17 along the sloped roof surface designed in the rectangular area 11, the sloped roof of complicated shape can be designed easily and efficiently. can do.

Next, a third embodiment of the present invention will be described with reference to FIG. The third embodiment is a method of changing a part of the parquet roof designed by the procedure shown in FIG. 1 into a gable roof. That is, first, in order to change the three parquet building portions of the parquet roof shown in FIG.
As shown in (b), the large part of the changed part 1
5 and 16 are extended up to the short side thereof (a line is inserted perpendicularly to the vertex b from the triangular base ac of the parcel ridge portion represented by the triangle abc in the plan view).

Next, as shown in FIG.
Of the line segment ab and line segment bc of each triangle abc, the drawn part (the part that was set as the ridge) is erased (the ridge is deleted), and the part that is not drawn is drawn (the ridge). Set). By the above procedure, the building part
Can be redesigned into a gable, and as shown in FIG. 5, the design can be redesigned into various pitched roofs having a gabled part and a gabled part or a gable-only roof (not shown). .

FIG. 6 shows a fourth embodiment to which the gathering-gable conversion method shown in FIG. 5 is applied. In the example shown in FIG. 6, each of the gathering roof portions of the gathering roof is changed to a gable roof. In each example, the dotted line part is an erased line (building). In addition, since the part of Fig. 6 is a double ridged part, first change'to gable side, then change to gable and delete the overlapping line (ridge) The design can be changed in the same way as in the example. Further, in the example of FIG. 4, only one gathering ridge portion-is changed to a gable, but it is also possible to similarly change two or more gathering portions-to a gable.

In contrast to FIGS. 5 and 6, FIG. 7 shows a fifth embodiment in which the design is changed from a gable to a shed. Figure 7
To change each gable part of the roof shown in (a) to a ridge, as shown in FIG. 7 (b),
By setting each corner ridge 13 and deleting a part of the large ridge 15 and the flat floor ridge 21 (the ridge previously set) outside the apex of the corner ridge 13, each is shown in FIG. 7 (c). The design is changed to a parquet roof. Note that FIG.
As shown in, when the set ridge 13 overlaps with another ridge (valley ridge 17), the line (ridge) may be deleted because the overlapping portion is on the same plane.

As shown in the above third to fifth embodiments, if the gable-gable conversion or the gable-gable conversion can be performed, for example, in a personal computer, one key is pressed. The roof shape can be easily changed by giving an instruction, and reliable and efficient planning can be performed by presenting roofs of various shapes at the time of meeting with the customer.

Further, since the roof once designed can be easily changed, even if the operator does not instruct the roof type, if the roof installation area 2 is set by a personal computer or the like, the roof 1 or the gable roof is automatically set. The roof 20 can be set to be designed, and the roof design work can be performed more easily.

FIG. 8 shows a sixth embodiment of the present invention. As in this embodiment, when the short side dimensions of the rectangular areas 11 and 12 in the roof installation area 2 are the same, the operator selects one of the rectangular areas 11 and 12, or prioritizes in advance. By setting the order, the sloping roof may be set from one of the rectangular areas 11 and 12.
For example, as shown in FIGS. 8 (A) to 8 (C), the slope roof of the rectangular region 11 which is long in the vertical direction in the drawing is set first,
After that, the pitched roof of the rectangular area 12 that is long in the lateral direction may be set, or conversely, as shown in FIGS. 6D to 6F, after designing the pitched roof of the rectangular area 12 first, 11
May be designed with a pitched roof.

FIG. 9 shows a seventh embodiment of the present invention. This embodiment shows an example in which a roof having a different shape can be constructed by setting a rectangular area even when the roof installation areas 2 are the same. That is, in FIG. 9A, three rectangular areas 31, 32, and 33 are set in the roof installation area 2,
The roof of the building is designed in the large rectangular area 31, and the roof of the building is designed on each short side of the smaller rectangular areas 32 and 33.

Further, in FIG. 9 (B), only one large rectangular area 35 including the concave portion 34 of the roof installation area 2 is set,
This is the design of the roof of a parquet building. At this time, a part of the gathering roof may be cut out in accordance with the concave portion 34 of the roof installation area 2. Further, FIG. 9 (C) shows three rectangular areas 31, 32, 3 in the roof installation area 2 as in FIG. 9 (A).
3 is set, and the parcel roof is designed in the rectangular area 31 having the shortest dimension among these, and the girders are provided on the shorter sides (the portions not included in the rectangular area 31) of the remaining rectangular areas 32 and 33. This is a design of the descent (eave) 36.

As described above, even if the roof installation areas 2 are the same, various pitched roofs can be designed by changing the settings of the rectangular areas 31 to 33, 35 and the roof type designation. When the roof design is automated by a personal computer, the input person may be allowed to set the rectangular areas 31 to 33, 35 and specify the roof type.
In addition, for example, as shown in FIG.
It may be designed such that a sloping roof is designed for 1 to 33, and 35 as a basic setting, and thereafter, the design can be changed as shown in FIGS. 9B and 9C by an operator's instruction.

FIG. 10 shows an eighth embodiment of the present invention. In this embodiment, of the rectangular areas 11 and 12 set in the roof installation area 2, the short sides 11A and 1 of the rectangular area 11 are set.
The horizontal dimension of 1B is shorter than the horizontal dimension of the short side 12A of the rectangular area 12, but when the height of the large building 15 is high because the slope of the sloped roof of the rectangular area 11 is large, that is, the horizontal dimension of the short side. This is an example of the case where the short side dimension becomes large as a result of multiplying by by a predetermined gradient coefficient. In this case, FIG.
As shown in (A), after designing a pitched roof in a rectangular area 11 having a large short-side dimension as a result of multiplying by the pitch coefficient,
0 (B), the short side 12A of the next rectangular area 12
Set the ridge 14 in the room, and as shown in Fig. 10 (C),
By setting the large ridge 16 from the drip ridge 14 and designing the valley ridge 17 from the intersection of the above-mentioned sloping roof and the large ridge 16, a sloping roof with different slopes (roof roof) is designed.

In this way, when there is a part with a different slope on one roof, the short side dimension is corrected by multiplying the short side dimension by the gradient coefficient corresponding to each slope, and the large building becomes the highest position. The roof can be designed from the roof portion (rectangular region), and an efficient roof design can be performed as in the above-mentioned embodiments.

FIG. 11 shows a ninth embodiment of the present invention. In each of the above-described embodiments, the slope roof is designed from a rectangular area having a large short-side dimension (including the case of being multiplied by the slope coefficient) among the rectangular areas set as the roof installation area. Is a sloping roof designed from a rectangular area with a short side. That is, as shown in FIG. 11A, the rectangular area 11 set in the roof installation area 2,
After designing a pitched roof in the rectangular area 11 in which the short sides 11A and 11B of 12 are small, as shown in FIG. 11B, the ridge 14 is formed in the short side 12A of the rectangular area 12 in which the short sides are large. Set the building 14 and the short side 12
The triangle abc consisting of A is translated and the triangle a'b '
Set c '. At this time, since the roofs have the same slope, the vertex c'of the triangle a'b'c 'with a large short-side dimension is large.
Will exceed the large building 15 with a pitched roof designed earlier.
Therefore, as shown in FIG. 11C, the triangle a'b '
The part of c ′ beyond the large ridge 15 may be folded back to the short side 12A side for design.

The example shown in FIG. 11 is an exceptional process to the last. For example, although the short side dimension of the rectangular area 11 was initially larger, the short side dimension of the rectangular area 12 was changed as a result of changing the floor plan design. When it becomes large, it may be used when changing the design of only the sloping roof on the side of the rectangular region 12. Note that the pitched roof of FIG. 11C can be set by designing the pitched roof from the rectangular area 12 having a large short-side dimension, as in the above-described embodiments.

According to each of the embodiments described above, since it is possible to easily design a pitched roof, it is possible for a sales person to design the pitched roof by himself, for example, even if he is not a specialized designer. It is also possible to change the design of the pitched roof quickly according to the customer's request, especially at the meeting with the customer. Therefore, it is possible to present various roof shapes to customers and hold meetings until they are fully satisfied, and it is not necessary to hold meetings every time the roof design is changed as in the past, so efficient meetings are possible. And design can be done. Further, since the design of the pitched roof is a simple method, even when it is automated by using a computer, a large system as in the past is not required, and the roof design can be automated by using a personal computer or the like. For this reason, for example, a salesperson can bring a laptop to the customer and immediately design a roof at the time of meeting with the customer, present a roof of various shapes, that is, a building, and have a meeting. It is possible to carry out a design that can respond to the customer's request with certainty.

The present invention is not limited to the above-mentioned embodiments, and modifications and the like within the range in which the object of the present invention can be achieved are included in the present invention. For example, in each of the above-described embodiments, the design of the gable roof and the parquet roof has been illustrated, but the present invention may be applied to the design of roofs of other shapes such as a roof of a purlin.

Further, not only a personal computer but also a large CA
The method of the present invention may be incorporated into a D system. In this case, since the processing method is simple, the design processing can be performed much more quickly than in the conventional case. Further, the present invention and the conventional design system are linked to each other to perform a schematic design by the method of the present invention.
The detailed design based on the roof type may be performed by a conventional system.

Further, in each of the above-mentioned embodiments, there is an embodiment in which only a plan view is illustrated for ease of explanation, but since the roof design can be processed by three-dimensional data, a personal computer or the like is particularly used. In such a case, a perspective view or a three-sided view may be displayed on the display so that the customer can easily understand the appearance.
