[A] Explanation of Terms First, the terms used in this specification will be explained.

As shown in FIG. 6, the names of the parts of the roof of the building include ridge, worship, gable, wall side, shed, eaves, valley, keraba, and eaves. Among these, there are large ridges (flat ridges), keraba, eaves, and valleys.

A "roofing material" 1 is a member that is attached to a roof having a substantially rectangular planar shape, and includes a slate roof, a galvanized steel plate, roof tiles, and the like. A slate roof is a material called thin roof material 1, colonial, or color vest. Slate is made of cement and fibers and is widely used along with roof tiles. Galvanium steel plate is also called sheet metal in building materials. It is used in various places outside the house and is made of aluminum-zinc alloy plated steel plate, and most of what is called a metal roof is made of galvanium steel plate.

The "roof shape" of the roof of the building includes a hip roof shown in FIG. 1, a gable roof shown in FIG. 2, a shed roof shown in FIG. 3, a flat roof shown in FIG.

A "roof plan" is a plan that shows the design of a building, especially the roof structure. It is a drawing that shows the roof, shape, finish, etc. when looking down on the building from directly above, like a plan view of the roof surface. It is a plan view of the outline of the roof, in which the shape, slope, materials, etc. of the roof are entered.

The "flow direction" is a direction along the inclination direction (slope direction) of the roof.

As shown in FIG. 5, the "gradient" of the roof includes 3, 4, 5, and 6 pitches. As shown in FIG. 5(a), the 3-inch slope refers to the state of being inclined 3-inch downward from 10-inch. "Sun" is a unit of length in shakukanho, and is defined as approximately 30.303 mm in Japan, which is 1/10 of shaku.

"Allocation" refers to arranging the allocation areas corresponding to the rectangular roofing materials 1 on the roof surface of the roof in order.

The "allocation area" corresponding to the roofing material 1 is not the size of the roofing material 1 itself, as shown by the hatched area in FIG. Rectangular area to be represented.

"Working width d" is the dimension of the part hidden from the vertical dimension b of the roof material 1 because the upper part of the roof material 1 overlaps the lower part of the upper roof material 1 and is hidden as shown in FIG. Except for c, it refers to the vertical dimension of the roof material 1 exposed from the outside.

"Genuine" represents a roofing material 1 that can be allocated to the roofing material 1 to be allocated in the same member size as shipped.

A "cut item" represents a member that is cut from the original size of a member to be allocated and that is to be allocated.

[B] Configuration of Roofing Material Allocation Device 10 The configuration of the roofing material allocation device 10 will be described with reference to the block diagram of FIG.

The roofing material allocation device 10 includes a personal computer (computer) control unit 12, the control unit 12 includes a display device 14 such as a liquid crystal display device, a printer 16, an input unit 18 such as a keyboard and a mouse, a scanner and a CAD device. A plan view input unit 20 consisting of, for example, is connected. The control unit 12 also has a roof shape storage unit 22 , a roof material storage unit 24 , a real data storage unit 26 , a cut data storage unit 28 and a storage unit 30 .

The roofing material storage unit 24 stores the types of roofing materials 1 and the vertical and horizontal dimensions of each roofing material 1 .

The genuine article data storage unit 26 stores data relating to the genuine article of the roofing material 1 .

The cut data storage unit 28 stores cut data of the roof material 1 .

As shown in FIGS. 1 to 4, the roof shape storage unit 22 stores various types of roof shapes, such as a hipped roof, a gabled roof, a shed roof, and a flat roof.

The storage unit 30 stores a roof material allocation program, a completed roof plan, and the like.

[C] Operating State of Roofing Material Allocation Device 10 Next, the flow chart of FIG. I will refer to them and explain them in order. The control unit 12 can realize the following functions by the roof material allocation program stored in the storage unit 30 . First, as shown in FIG. 10, the roof to which the roof material allocating device 10 allocates the roof material 1 is a partially modified hipped roof.

1. In step S1, a plan view is input (see FIG. 11).
A plan view of a building is input from the plan view input unit 20 . At this time, if the building has two or more floors, the floor plan under each roof on each floor is input. At the time of this input, the actual size of the floor plan is also input. The input method is a scanner, CAD data, PDF data, or the like. The control unit 12 sets an absolute coordinate system in consideration of the actual size of the input plan view. Here, the east-west direction is the x-axis direction, the north-south direction is the y-axis direction, the due east is the +x-axis direction, and the due north is the +y-axis direction.

2. In step S2, an exterior wall line is input (see FIG. 11).
The input unit 18 inputs the outer wall line of the floor plan of the building. This input is performed by moving the mouse along the outer wall in the plan view and tracing it with the cursor, or by inputting the numerical value representing the position of the outer wall in the absolute coordinate system and the actual dimension data of the outer wall line.

3. In step S3, the extension width is input (see FIG. 11).
A numerical value of the extension width, which is the distance from the outer wall line to the tip of the roof, is input through the input unit 18 . The width may be the same for all the north, south, east, and west exterior wall lines, or may be different for each of the north, south, east, and west exterior wall lines.

4. In step S4, border lines of north, south, east, and west are created (see FIGS. 11 and 12).
The control unit 12 creates a frame line indicating the outer frame of the roof plan at a position projected from the outer wall line by the protrusion width and the actual size data of the length of the frame line. This actual size data is calculated by the control unit 12 from the actual size data of the length of the outer wall line in the plan view and the numerical value of the width.

5. In step S5, a gradient such as the 3-inch gradient shown in FIG. 5 is input.
The slope of the roof is input through the input unit 18 . Note that the slope may be input after specifying the roof shape in step S6. In this case, instead of inputting the same slope for all roof surfaces, the slope may be input for each roof surface.

6. In step S6, the roof shape is specified.
The input unit 18 identifies the roof shape of one roof from a plurality of roof shapes such as a hipped roof, a gable roof, or a shed roof as shown in FIGS. 1 to 4 stored in the roof shape storage unit 22. .

7. At step S7, a roof line is created.
The control unit 12 creates a roof line corresponding to the specified roof shape in the range surrounded by the frame lines.

(1) When the specified roof shape is a hipped roof (see Fig. 1)
A case of creating a roof line for a hipped roof whose specified roof shape is shown in FIG. 1 will be described.

First, an eaves attribute is added to each of the north, south, east, and west borders. It is assumed that each frame line (eaves) bends when it intersects.

Second, when adjacent frame lines (eaves) intersect at 90°, a corner ridge is created at a position diagonally 45° from one of the adjacent frame lines.

Third, when adjacent frame lines (eaves) intersect at 270°, a trough is created at a position diagonally 135° from one of the adjacent frame lines.

Fourth, when one corner ridge and another corner ridge intersect, the one corner ridge and the other corner ridge end at that position.

Fifth, a flat ridge is created by connecting a point where two corner ridges intersect with a point where other two corner ridges intersect.

As described above, the roof line of the roof plan for the hipped roof can be created. Moreover, with this method, the roof line can be created not only for a perfect hipped roof as shown in FIG. 1, but also for a deformed hipped roof as shown in FIG.

(2) When the specified roof shape is a gable roof (see Fig. 2)
A case of creating a roof line in a gable roof whose specified roof shape is shown in FIG. 2 will be described.

First, the attribute of eaves and the attribute of "Keraba" are added to the north, south, east, and west borders.

Secondly, a flat ridge is created on the roof surface between the eaves facing each other.

As described above, the roof line of the roof plan for the gable roof can be created.

For example, the roof of the second floor of the building shown in FIG. 6 corresponds to the gable roof.

(3) When the specified roof shape is a shed roof (see Fig. 3)
A description will be given of a case where a roof line is created for a shed roof whose specified roof shape is shown in FIG.

First, with respect to the north, south, east, and west borders, the attribute of the eaves and the attribute of "Keraba" or the attribute of the wall are added.

Second, the flow direction is determined so that the position of the eaves is at the position of the lowest slope.

As described above, a shed roof does not have a roof line, and a roof plan can be created only by determining the flow direction.

For example, the eaves on the first floor of the building shown in FIG. 6 correspond to the shed roof.

Even if the specified roof shape is the flat roof shown in FIG. 4, the slope is only 0, and the rest is the same as the shed roof. In this case, the position of the eaves can be determined arbitrarily.

8. In step S8, a roof surface is created.
The control unit 12 creates a plurality of roof surface candidates surrounded by frame lines and roof lines.

The control unit 12 sets the flow direction of the roof surface candidate.

The control unit 12 inclines the roof surface candidate in the flow direction based on the slope, obtains the actual size data of the roof line, and creates the roof surface corresponding to the actual size data of the frame line and the actual size data of the roof line.

As a result, as shown in FIG. 13, the roof plan of the roof surfaces Y1 to Y8 to which the roof material 1 is not assigned is completed.

9. In step S9, the roof material 1 is specified.
The input unit 18 specifies a roofing material 1 (for example, a slate roof) to be allocated from a plurality of types of roofing materials 1 stored in the roofing material storage unit 24 . The type of roofing material 1 , the horizontal dimension a, the vertical dimension b, and the working width d specified from the roofing material storage unit 24 are input to the control unit 12 . The identification of the roof material 1 is not limited to after step S8, and may be performed between steps S1 to S7.

10. In step S10, the allocation area corresponding to the roof material 1 is allocated to the roof surface (see FIGS. 13, 14 and 15).

(1) Allocation Rule of Allocation Area Corresponding to Roof Material 1 on Roof Surface First, the allocation rule of allocation area corresponding to roof material 1 on the roof surface will be explained.

If there are multiple roof surfaces Y1 to Y8 in the roof plan to which the roof material 1 is not assigned, the roof material 1 is attached to the roof surface existing in the clockwise direction from the easternmost roof surface Y1 to the roof surface Y8. The corresponding allocated areas are allocated in order (see FIGS. 10 and 13).

The rectangular layout areas are arranged side by side in order from the left end (allocation start point P) on the eaves side of the roof surface to the right end toward the right so that they do not overlap. This arranging work means allocation. It should be noted that "from the left end (allocation start point P) to the right end toward the right" is an expression for easy explanation in FIG. 13, and actually means from one end of the eaves to the other end. is. Next, in the next stage, the allocation areas are allocated in order from the left end to the right end of the eaves. Further, the allocation areas are allocated in the same order for the next stage, and this process is repeated until the allocation areas are allocated up to the top level of the roof surface (see FIG. 14).

Lay out so that the horizontal direction of the roof material 1 and the frame line of the roof surface are parallel (see FIG. 14).

Allocate from the lower stage so that the vertical direction of the roof material 1 and the flow direction of the roof surface are parallel (see FIG. 14).

Each position in the roof surface, the frame line, the flat ridge H1, the flat ridge H2, the corner ridge L1, the corner ridge L2, and the corner ridge L3 are indicated by the position of the absolute coordinate system (see FIG. 14).

The assigned position is indicated by the number assigned in order by the roofing material 1 and the position in the absolute coordinate system.

An identification number is stored as to whether the roof material 1 at each allocation position is genuine or cut. Then, the real thing and the cut thing are processed. This will be discussed later.

(2) Allocation Method to Roof Surface Y1 First, the control unit 12 starts from the left end (allocation start point P) of the position (first stage) closest to the eaves side of the roof surface Y1 on the east side toward the right end. Allocate allocation areas in order. As for the determination of the left end, if there is an allocation area on the line of the corner ridge L1 on the left of the roof surface, the left end is determined. The right end is judged as the right end if there is an allocation area on the line of the corner ridge L2 on the right side of the roof surface (see FIG. 14). The number of layout areas arranged in a row at the position of the frame line is determined by dividing the actual size data f of the horizontal dimension of the frame line by the horizontal dimension g of the layout area (=f/g). Fractions of the divided number (=f/g) are treated as cuts, which will be described later.

Secondly, when the allocation of the first stage is completed, the control unit 12 sequentially allocates the allocation areas from the left end to the right end of the second stage. At this time, the layout areas are arranged in a zigzag manner by shifting the layout position of the rectangular layout area in the first row by half the size of the layout area in the lateral direction (see FIGS. 14 and 15). In other types of roofing materials 1 (for example, roof tiles), the allocation areas may be allocated in a grid pattern.

The control unit 12 similarly performs allocation up to the uppermost stage of the roof surface Y1. This judgment assumes that when the allocation position of the allocation area reaches the position of the flat roof H1, allocation is made up to the top level of the roof surface (see FIG. 14). Allocation of the roof material 1 to the roof surface Y1 on the east side shown in FIG. 14 is now completed. It should be noted that, during this process, the processing of the genuine article and cut article (steps S21 to S41), which will be described later, is performed.

Next, the roof surface Y2 is allocated, and finally the roof material 1 is allocated to all the roof surfaces Y1 to Y8 as shown in FIG. 16 to complete the roof plan.
11. In step S11, a roof plan with allotted roof materials 1 is output (see FIG. 16).

The control unit 12 displays the roof plan to which the roofing materials 1 shown in FIG. Further, the control unit 12 stores the roof plan to which the roof materials 1 are allocated in the storage unit 30 .

If there are other roofs on the same floor of the building or on other floors, a roof plan for each roof is created in the same manner.
12. Processing of Genuine Objects and Cut Objects Next, the processing of genuine objects and cut objects in the layout of the roofing materials 1 will be described with reference to the flow chart of FIG.

In step S21, in the allocation area allocated to the roof surface Y1, a portion of the roof material 1 in which the original can be used as it is is set as the "genuine allocation area". In addition, the genuine article identification number of the genuine article allocated to each genuine article allocation area is set. For example, the allocation area filled with hatching lines in FIG. 15 can be set as the genuine allocation area. At this time, the positions of the coordinate points of the corners of each real object layout area are calculated as the layout positions. This calculation is performed based on the coordinate position of each point on the roof surface Y1 in the absolute coordinate system. When allocating the real thing, since the coordinate positions are stored for the points at both ends of the top, bottom, left, and right sides of the roof surface, when each real thing allocation area is included in each side, , each true allocation area ends at each edge.

In step S22, among the allocation areas of the roof surface Y1, areas other than the real object allocation area are set as "cut object allocation areas". Since the coordinate positions are stored for the points at the ends of the top, bottom, left, and right sides of the roof surface, when each cutting object allocation area is included in each side, each cutting object allocation area The region shall end.

In step S23, first, a cut-out allocation area for allocating cut-outs is set. This setting may be made from the allocation start point P or from an arbitrary point. In this description, the allocation start point P is set as the cut object allocation start point, and when the allocation of the cut objects is started in order from this cut object allocation start point in the upward direction and all the objects are allocated in the upward direction, the next allocation is performed. The order of allocation to the cut object allocation area on the right side of the starting point P is set. Note that this order may be determined arbitrarily.

In step S24, the vertical and horizontal dimensions of the set cutout allocation area are calculated. In this calculation method, calculation is performed from the coordinate points of the corners of the cut object allocation area for the allocation. Then, the cut-out data corresponding to the cut-out allocation area is retrieved from the cut-out data storage unit 28 and called up.

This step is omitted because there is no cutting data at the first position of the first roof surface Y1. However, since this cut object data exists in the allocation of the cut object in the second cut object allocation area on the roof surface Y1 and the allocation on the roof surface from the next time onward, retrieval is performed from among the cut object data.

As the "cutting allocation condition" for this search, the first condition is the cutting object having the horizontal and vertical dimensions larger than the cutting allocation area, and the second condition is the cutting object A search is made for the smallest difference between the horizontal or vertical dimension of the allocation area and the horizontal or vertical dimension of the cut object.

In step S25, if there is no cut piece having the horizontal and vertical dimensions larger than the horizontal and vertical dimensions of the cut piece allocation area, which is the first condition of the cut piece allocation conditions, it is determined that there is no corresponding cut piece. do. Also, if there is a cut object that meets the first condition, the process proceeds to step S26.

In step S26, it is determined whether or not the size of the corresponding cut object can be allocated to the cut object allocation area. If not, the process proceeds to step S29. This determination is made by comparing the vertical and horizontal dimensions of the stored cut object with the vertical and horizontal dimensions of the cut object allocation area.

In step S27, since the cut object can be allocated as it is, the cut object is allocated to the set cut object allocation area, and the cut object identification number of the cut object is set to the cut object allocation area. Then, the position of the coordinate point of the corner of the cut object layout area is calculated as the layout position.

In step S28, the cut item identification number of the allocated cut item is deleted from the cut item data storage unit 28, and the process proceeds to step S40.

In step S29, since it is determined in step S26 that the cut object cannot be laid out in its size, the cut object is cut in accordance with the cut object corresponding layout area.

In step S30, the cut object is allocated to the set cut object allocation area. Then, the cut object identification number of the cut object allocated to the cut object allocation area is set, and the position of the coordinate point of the corner of the cut object allocation area is calculated as the allocation position.

In step S31, the cut item identification number of the allocated cut item is deleted from the cut item data storage unit 28, and the process proceeds to step S32.

In step S32, it is determined whether or not the part remaining after cutting the cut object can be newly registered as a cut object. Together with the lateral dimension, it is stored in the cut object data storage unit 28, and the process proceeds to step S40. If the remaining portion cannot be registered as a cut item, the data is discarded in step S34 and the process proceeds to step S40. Here, as a condition for judging whether or not the remaining part can be registered as a cut object, for example, a state in which all parts other than the genuine object and the part having the inclined surface of the cut object can be used. .

In step S35, since it is determined in step S25 that there is no corresponding cut object, a new genuine object is cut corresponding to the set cut object allocation area.

In step S36, the cut object is allocated to the cut object allocation area. In this case, a newly created cut object identification number is set, and the position of the coordinate point of the corner of the cut object layout area is calculated as the layout position.

In step S37, it is determined whether or not the remaining portion of the cut genuine article can be registered as a cut article. This determination method is the same as the cut item determination condition in step S32. Then, if the object satisfies this cut object determination condition, the remaining portion is registered in the cut object data storage unit 28 as a cut object. In this case, the newly created cut object identification number, vertical dimension, and horizontal dimension are registered. On the other hand, if it does not meet the cutting judgment condition, it is discarded in step S39.

In step S40, since a cut object has been allocated to one cut object allocation area, it is determined whether or not to proceed to the next cut object allocation area. If the cut objects have been allocated to all the cut object allocation areas, the process proceeds to step S41; otherwise, the process returns to step S24.

In step S41, since the real object and the cut object have been assigned to all the real object allocation areas and the cut object allocation areas, the allocation of the roof surface is finished, and the real object identification number and its allocation position assigned to each allocation area are determined. Also, the cut item identification number and its allocation position are stored.

In step S42, this allocation process is sequentially performed clockwise from the roof surface Y1 on the easternmost side of the roof plan. When all the roof surfaces Y1 to Y8 have been assigned, the assignment process ends. At this time, the cut objects are handled on a certain roof surface, and the cut objects not used on that roof surface are used for allocation on the next roof surface. Then, the number of roofing materials 1 used for the allocation of all roof surfaces (the total number of genuine materials and the number of genuine materials used for cutting) is stored.

Furthermore, the control unit 12 similarly performs allocation processing of the real roofing materials 1 and the cut pieces for roofs on the same floor of the building or on other floors, and manages the cut pieces used for each roof. I do.

[D] Effect According to this embodiment, the roof material 1 is allocated by inputting the plan view of the building, inputting the outer wall line of the plan view, inputting the extension width and slope, and specifying the roof shape. You can get a roof plan that has been

Also, if one roof shape is specified from a plurality of types of roof shapes, a roof line can be created on the roof surface regardless of which roof shape is suitable.

Moreover, if one roofing material 1 is specified from a plurality of kinds of roofing materials 1, any roofing material can be allocated.

Moreover, the horizontal dimension of the allocation area of the roofing material 1 can be made by the horizontal dimension of the roofing material 1, and the vertical dimension of the allocation area can be made by the working width.

In addition, the slope of the roof shape can be freely set.

In addition, first, the real object is assigned to one roof surface, then the cut objects are assigned in order, and the most matching cut object can be assigned without waste. Cuts can be used. Therefore, the number of roofing materials 1 to be used can be minimized, and the cost can be reduced.
