[0002]

2. Description of the Related Art In recent years, with the remarkable progress of personal computers, introduction of a CAD system for drawing drawings has been advanced. It has become common to use CAD systems to draw construction drawings, such as installation drawings required for building sash construction work. The sash construction work in the building is carried out based on the sash installation drawings. This inset is a drawing that specifically specifies the structure of the skeleton, the shape of the opening, the type and size of the external finishing member, the type and size of the internal finishing member, and various members necessary for mounting the sash. .

[0003] In a conventional CAD system for creating a fit diagram of a sash of this type, the type and shape of the skeleton are previously determined.
Elements such as exterior finishing members, interior finishing members, and fittings such as sashes are registered, and by designating codes and dimensions assigned to these elements, they can be called up on the screen for drawing.

[0004]

SUMMARY OF THE INVENTION Conventionally, an inset drawing is called CA
In the case of D drawing, first, specify the code in order from the skeleton side, such as the type, shape, external finishing member, and internal finishing member of the skeleton, and then specify the parts of the fittings such as the sash with the code, Only by inputting the parameters specifying the details, the following figure is drawn on the screen. After that, the procedure of inputting numerical values, making corrections to the drawings, and completing an accurate drawing is taken. Therefore, at the stage of specifying the code, the drafter must work while imagining the drawing in his head,
Working efficiently and efficiently requires expertise in architecture and considerable skill in CAD.

[0005] Further, in a building, although there are many types of fittings such as sashes and shojis, they are products having a fixed characteristic provided by a manufacturer. On the other hand, the structure of a building, although there are exceptions such as prefabricated houses, usually have individual characteristics and each building has an atypical property that no two buildings are the same. As described above, the skeleton of a building is concretely different depending on the building, while fittings such as sashes are fixed to some extent with different shapes and sizes. In short, the sash is selected according to the skeleton while the skeleton differs from building to building and the design of the details is often changed. Therefore, it is not easy to make corrections when there is a design change in the construction drawing, such as modifying the skeleton side if there is a design change, and then modifying the sash accordingly. There is. For this reason, if there is a design change in the meeting before construction, it takes time and effort to correct the drawing again and to make a meeting again for confirmation.

[0006] Therefore, an object of the present invention is to solve the problems of the above-mentioned prior art, and to provide expertise in building and CAD.
It is therefore an object of the present invention to provide a CAD system for construction drawings that enables intuitively and visually intuitive and visual drawing of drawings, etc., without requiring any skill in the above.

Has become. Details of the CAD support data will be described later.
In the CAD system for construction drawings of the present embodiment, by reading CAD support data and pasting the drawing data by cut-and-paste, for example, a construction drawing 16 such as a sash fitting diagram can be easily created.

Next, FIG. 2 shows an example of a sash to be drawn by the CAD system for construction drawings according to the present embodiment. FIG. 2 is an inset diagram in which the building frame is a reinforced concrete structure (RC). In the drawing, what is shown on the left side is vertical alignment, and what is shown on the right side is horizontal alignment. In this case, only the right alignment is shown because it is symmetrical. In FIG. 2, when the sash is set up and down in outline, reference numeral 20a is an outer sliding door and 20b is an inner sliding door. 21 is an upper frame of the sash, and 22 is a lower frame of the sash. The vertical fit is a diagram in which necessary and sufficient information about the types of members necessary for mounting and mounting the upper frame 21 and the lower frame 22 in the skeleton opening 27, their dimensions, mounting positions, and the like is included.

A tile 24 is provided on the outer surface of the reinforced concrete 23 as an exterior material. Inside the reinforced concrete 23, a board 26 is attached as an interior material with a heat insulating material 25 interposed therebetween. The upper frame 21 is attached to a window frame made of an aluminum table board 27 and fastened to the insertion reinforcing bar 28. The lower frame 22 is a wooden window frame 2
9 and fastened to the insertion rebar 30 via a fastening member 31. Reference numeral 32 denotes a drain plate attached so as to protrude outward from the lower frame 22, and reference numeral 33 denotes caulking for closing a gap between the upper frame 22 and the tile 24.

The right and left fits indicate the types, dimensions, mounting positions, etc. of the members required for mounting the vertical frame 34 of the sash. Since the components of the building frame are the same as those in the vertical direction, the same components are denoted by the same reference numerals and description thereof will be omitted.

Next, FIG. 3 is a diagram showing a directory structure of the storage device 14 in which CAD support data is stored.
In the inset folder 40, in addition to the basic drawing folder 41, an upper and lower holder 42, a left and right folder 43,
There are an upper frame storage folder 44, a lower frame storage folder 45, a right frame storage folder 46, a left frame storage folder 47, and a common member folder 48, and the drawing data classified by region is any of the folders corresponding to the region. Is stored in

In the basic drawing folder 41, basic drawing data serving as a template for creating the fit-in drawing shown in FIG. 2 is stored. Since there are various types of sash fittings at the opening of the building, the building is first classified according to the type of the structure of the building. That is, in this embodiment, three types of typical reinforced concrete structures (hereinafter abbreviated as RC), factory-produced concrete structures (hereinafter abbreviated as ALC), and steel frame structures are shown as types of frame structures.
Types are listed as major categories. Actually, there are other types of the frame structure of the building, but in the present embodiment, these three types are used in order to make the story easier to understand.
The basic drawing data belonging to each of the folders 50, 51, and 52 for RC storage, ALC storage, and steel frame storage are respectively subdivided into predetermined types and stored in one of the type folders.

This type is classified according to the combination of the exterior material and the interior material of the frame. For example, if it fits in RC, the exterior material is tile and the interior material is board (type A
1) There are exposed bare concrete without an exterior material and an interior material of a board (type A2), and an exterior material of a tile with a skeleton opening connected to a floor of a flooring (type A3). In the case of ALC, the outside is bare concrete and the interior material is board (type B1),
There is a case where the exterior material is a tile and the interior material is a board (type B2). If it fits in a steel frame, there are a case where the exterior material is slate and the interior material is a board (type C1), and a case where the exterior material is siding and the interior material is a board (type C2).

Such basic drawing data is obtained by utilizing drawing data of a large number of properties actually constructed in the past, and classifying drawing data suitable for use as a model among the above-described types. , Stored in folders of each type. Also, for drawing data A11, A12,... Belonging to the same type, for example, type A1, there are prepared ones corresponding to drain plates having various dimensions within the same type and those having different specifications in small points. ing. The same applies to drawing data belonging to other types.

Next, the drawing data belonging to the vertical fit folder 42 is the drawing data of the drawing showing the vertical fit shown on the left side of the fit diagram of FIG. Further, the drawing data of the upper frame and the lower frame are separately prepared from the upper and lower frames, and they are stored in the upper frame folder 44 and the lower frame folder 45.

Similarly, the drawing data belonging to the left-right fit folder 43 is the drawing data of the right-right fit shown on the right side of the fit-in diagram of FIG. further,
Drawing data for the right frame and the left frame are separately prepared, and are stored in the right frame folder 46 and the left frame folder 47.

The upper and lower folder 42, the left and right folder 43, the upper frame folder 44, the lower frame folder 45, the right frame folder 46, and the left frame folder 47 have the same lower order as the basic drawing folder 41. The drawing data is largely classified according to the structure of the skeleton, and then is classified into a predetermined type and stored in a folder of any type. Here, the types of the frame structure, which are the major classification items, are RC fit, ALC fit, and steel fit as in the case of the basic drawing data shown in FIG. FIG. 4 shows the lower directory structure of the upper frame folder 44 in which the drawing data of the upper frame is stored. The lower directory structure is the same for the upper and lower folder 42, the left and right folder 43, the lower frame folder 45, the right frame folder 46, and the left frame folder 47. The drawing data of FIG.

In FIG. 4, in the upper frame folder 44, as in the case of the basic drawing folder 41 in FIG.
Each is roughly classified by frame structure and further classified by the combination of exterior and interior materials. These types are the same as the basic drawing folder 41.

FIG. 5 shows an example of a case where the frame has an RC structure and the upper frame fits in a type A1, that is, the outer material is a tile and the inner material belongs to a board type. FIG. 5 (a) shows a model that fits in an upper frame applied to a sash in which a frame angle for mounting is integrated,
For 0, a wooden frame is used. FIG. 5B shows a frame type in which the frame angle 61 for mounting is formed separately from the sash and is mounted on the window frame 60. FIG. 5C shows a model that fits in an upper frame using an aluminum table board 27 as a window frame. For each of these models, drawing data in which the expected dimensions such as the width of the exterior material are changed by a predetermined pitch, for example, every 5 mm, are prepared for each of those using the same size drain plate.

Next, referring to FIG.
Reference numeral 8 denotes a part commonly used in sashes regardless of the type of the frame. As this common component, in FIG.
There are drainboard plates, aluminum plates, picture frame angles, sashes, and shoji. In the common member folder 48, a folder is provided for each common component, and its drawing data is stored.

FIG. 6 shows an example of drawing data of these common members.
Shown in FIG. 6 shows image data of an aluminum table board.
Aluminum tabletops are available for upper frames (rows A and B), lower frames (row C), and vertical frames (rows D and E).
Many drawing data are prepared by changing the width of the projection at a pitch of 5 mm. As for other common parts, it is the same that a large number of parts whose dimensions are changed at a predetermined pitch are prepared.

Next, a description will be given of a procedure for creating a sash fit-in diagram on the CAD system of the personal computer 10 using the drawing data as described above. The drawing creation procedure reads the basic drawing data of the template in the basic drawing folder 41 and displays it on the screen. Thereafter, the upper and lower folder 42, the left and right folder 43, the upper frame folder 44, the lower frame Folder 4
5, right frame folder 46, left frame folder 4
7. Appropriate drawing data is cut from the common member folder 48 and pasted by editing to create it.

FIG. 7 is a diagram showing an example of the creation. FIG.
(A) shows the read basic drawing data. In the basic drawing data, the skeleton has an RC structure. As the basic drawing data, the data closest to the drawing to be created is selected. The CAD system has a function of displaying a drawing data list screen when a corresponding folder is selected from the RC storage folder 50 of the basic drawing data folder 41 in FIG. 3 from a dialog box opened at the time of reading. I have. Therefore, the basic data may be selected from the list screen. The list screen display when selecting such drawing data is the same as when selecting other drawing data.

Therefore, in the read basic drawing, if the fit in the upper frame is different from the layout drawing to be created, the range 100 of the fit in the upper frame is designated and erased. Next, when the window frame shown in FIG. 5C is changed to the type of the aluminum table board, the type of the frame is set to the type A.
Select the aluminum plate type folder in the folder of 1. Then, a drawing data list screen is displayed, and the drawing data is selected from the screen. Then, a range 102 for pasting the drawing data is set, and the drawing data may be pasted.

Next, assuming that the width of the aluminum plate 27 is different, the portion of the aluminum plate is deleted, and then the folder of the aluminum plate of the common member folder 48 in FIG. It is sufficient to select the drawing data of the aluminum table board of the required size from the open list screen such as 6 and paste it. Hereinafter, cut-and-paste editing is performed in the same manner to complete the drawing.

After the basic drawing data of the template is selected in this way, the drawing data is pasted on the screen from the lower structure to the detail by cut-and-paste, so that the desired structure of almost any frame structure can be obtained. It becomes possible to easily create a fit-in diagram visually.

Further, since the drawings can be easily modified by cutting and pasting, if a CAD system is constructed with a notebook-type personal computer as in this embodiment, it is possible to arrange the drawings on the spot while meeting with the customer. It is also possible to make corrections.
