The present invention relates to an automatic creation device for architectural plans using the dDesign system.

[Conventional technology] For example, when building a wooden house, the perimeter line, room area, pillars, fittings, roof, ventilation holes, girder lines, etc. are determined based on various data obtained from the floor plan of the building, and these perimeter lines, Create a floor plan of the foundation, each floor, and each floor shed using the room area, pillars, fittings, roof, ventilation holes, and girder lines, and from these plans, calculate the thickness of the pillars required to actually construct the building. We are trying to determine the strength of the beam.

However, in the past, the creation of such plans was generally done manually, so
It requires a lot of time and effort, and also costs a lot of money, so it has the disadvantage of being economically disadvantageous.

[Problem to be solved by the invention] As described above, in the past, the creation of architectural plans relied on manual labor, which took a lot of time and effort, and also cost a large amount of money. It also had disadvantages economically.

Incidentally, recently, CAD systems have come to be used in the design process for graphics and analytical calculations in the field of architecture as well. However, the use of such a CAD system is only a small part of the design process, and important parts of the design activities currently rely on human labor as described above.

The present invention has been made in view of the above circumstances, and is an architectural device that can create devices such as foundations, each floor, and each floor shed in a short time with simple effort by using a CAD system. The purpose is to provide an automatic creation device.

A storage means storing a control program, and a method for creating a foundation replacement, each floor device, and each story shed device in accordance with the control program stored in the storage means using the data and parameters inputted from the input means. It consists of a control means for executing various controls, and a display means for displaying the foundation replacement, each floor device, and each floor shed device created under the control of this control means.

[Function J] As a result, according to the present invention, by simply inputting predetermined parameters as well as data regarding at least the floor plan of the building, foundation replacement, each floor system, and each floor shed system can be controlled by a pre-stored control program. It is now possible to automatically create each of these devices, making it possible to create these devices in a short time and with simple effort.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the circuit configuration of the same embodiment. In the figure, 1 is a control unit (CPU), and this CPU includes:
A database 5 consisting of a program ROM 3, a data RAM 4, and an external storage device is connected via a bus 2.

Here, the program ROM 3 stores in advance various control programs necessary for creating the device. Further, the data RAM 4 stores data that needs to be temporarily stored during device creation. The database 5 stores in advance display patterns and the like necessary for creating various figures constituting the device.

Further, a keyboard interface 6 and a display interface 7 are respectively connected to the CPUI via a bus 2.

Here, a keyboard 8 is connected to the keyboard interface 6, and data input from the keyboard 8 is taken into the CPUI via the keyboard interface 6.

Further, a display device 9 consisting of a CRT display is connected to the display interface 7, and display data output from the CPU 1 is displayed on the display device 9 via the display interface 7.

The CPU 1 is composed of, for example, a microcomputer, and is configured to execute various controls for diagram creation based on a control program necessary for substitute creation written in a program ROM 3.

Next, the operation of the embodiment configured as above will be explained.

First, data regarding the building's floor plan and roof equipment are entered manually, as well as automatic generation parameters for automatic equipment generation. In this case, input of the plan view and the roof device is performed by inputting necessary coordinate data and the like from the keyboard 8 and then drawing the drawing on the display device 9.

When creating a basic replacement from this state, when the basic device creation menu is selected, the flowchart shown in FIG. 2 is executed by the CPU.

In this case, in step A1, the first floor perimeter line and room area (room enclosing line) are determined from the floor plan data entered in advance, and the process proceeds to step A2, where the foundation is constructed from these - tread perimeter line and room area. generate. In this case, lines with the same length as the rising foundation width are generated directly to the foundation at both ends of the location where the entrance door is input.

In step A3, when the bathroom, entrance, back entrance, and garage of the room area are determined, a dirt floor space is generated.

In addition, if there is a porch, a dirt floor will also be generated within the perimeter line of the porch.

In step A4, ventilation holes are generated. In this case, a ventilation hole will be generated at the position of the ventilation hole input in the roof device.

Then, in step A5, if it is determined that the area of the room is not a bathroom, an entrance, a back door, or a garage, a bundle of stones is generated.

In this case, the pile stones are generated inside the room enclosing line, in a range excluding the area on the enclosing line, from the origin at the floor pile pitch based on the automatically generated parameters.

In this way, the basic device is created, and the results are displayed on the display device 9.

Next, when creating a first floor plan map, when the menu for creating a first floor plan map is selected, the flowchart shown in FIG. 3 is executed by the CPUI.

In this case, in step B1, the first floor perimeter line and room area (room enclosing line) are determined from the floor plan data entered in advance, and the process proceeds to step B2, where a foundation is generated from these - floor perimeter line and room area. let

In this case, the foundation is generated for the entire room area, but it is cut at the point where the entrance fittings are inserted.

In step B3, the bathroom, entrance, back door, etc. in the room area,
Generates joists in rooms other than stairs and garages. in this case,
As shown in FIG. 6, the joists 11 are generated parallel to the first line of the room enclosing line 10 at the joist pitch of the automatically generated parameter. The generated pitch here can be set using automatic generation parameters, such as how many equal parts the reference pitch should be divided into the enclosing range for Western-style room names, and how many equal parts the reference pitch should be divided into the enclosing range for Japanese-style rooms. This will allow you to allocate the joists.

In step B4, edge joists are generated. in this case,
As shown in FIG. 6, the edge joists 12 are 10 parallel only to the joists 11 of the room enclosing line 1o where the joists 11 are generated.
0 ■ Generate on the inside, parallel to the joist 11.

In step B5, large pulls are generated in rooms excluding bathrooms, entrances, back doors, stairs, and garages within the room area.

In this case, as shown in FIG. 6, the pitch 13 is orthogonal to the joist 1 for each room area, and the pitch is generated using the pitch of the automatically generated parameter.

Then, in step B6, if the room area is 7m2 or more excluding the bathroom, entrance, back door, stairs, and garage,
Generate a foundation flint inside this room.

In this way, the first floor map is created, and the result is displayed on the display device 9.

Next, a case will be described in which a floor device on a floor above the first floor and a shed device at the same height are created.

In this case, the floor equipment on floors other than the first floor and the shed equipment on the other than the top floor will be at the same height, for example, the 1st floor shed floor plan for the 2nd floor floor plan and the 2nd floor shed floor plan for the 3rd floor plan. There is an inseparable relationship between them. Therefore, in this case, each device at the same height is calculated together, and after this calculation, the devices on each floor are separated.

In this case as well, select the appropriate device creation menu.

Then, the flowchart shown in FIG. 4 is executed by the CPUI.

First, in step C1, the lower floor perimeter line and room area (room enclosing line) are calculated from the input plan view, and step C1
Proceed to step 2 and generate general rice from above the room border line on the lower floor. In this case, the reference pitch is P (initial value 910m/
m), if a fitting with a width exceeding 2P is input, a beam will be generated with that fitting width.

In step C3, beams are generated from areas other than the room enclosing line on the lower floor. In this case, if the length of each room enclosure on the lower floor is rectangular and the length in the X direction and Y direction is 2P or more, the length of the enclosure in the short side direction, X direction, and Y direction is If they are the same, they are generated on a virtual grid 2P from the origin in the X direction. If the number of sides is greater than that of a quadrilateral, a beam is generated on the shorter side by tracing the enclosing line and reaching the opposite side at a point where the interior angle is 270 degrees. In this case, if the length of the generated beam exceeds 2P, or even if it is less than 2P but there is a column on the floor above the beam line and a column on the floor below is not at the same point, the general beam is replaced with a beam.

Otherwise, a general beam will be generated. Furthermore, if it is not checked whether there are columns of the lower floor or beams of the relevant floor at both ends of the generated beam, replace the pillars of the nearest lower floor in both directions from the intersection with beams. .

Next, in step C4, a beam is generated on the room enclosing line on the upper floor. In this case, overlay the room enclosing line on the upper floor on the generated general beams and beams on the lower floor, and use the non-overlapping enclosing line as a beam candidate, and that line intersects with the beam on the lower floor. If so, split the candidate line for the floor beam above the intersection point. After that, those beam candidate line segments whose length exceeds 2P are generated as beams, and those whose length is less than 2P are generated as general beams. Here, even if it is 2P or less, if there is a column on the upper floor on the beam line and a column on the lower floor is not at the same point, replace the general beam with a beam. Furthermore, if it is not checked whether there are pillars of the lower floor or beams of the relevant floor at both ends of the generated beam, the spaces between the pillars of the nearest lower floor in both directions from the intersection are replaced with beams.

Next, in step C5, the room area and the stairs from the balcony,
Generate joists in rooms other than the atrium.

In this case, as shown in FIG. 7, the joists 21 are generated on the balcony 22 parallel to the first line of the enclosing lines 20 at the joist pitch of the automatically generated parameter.

The generated pitch here is set by an automatic generation parameter as the number of equal parts of the reference pitch for the Western-style enclosing range of the room name, and the joists are allocated based on this value. All floors other than the first floor have Western-style pitches.

In step C6, edge joists are generated. in this case,
As shown in FIG. 7, the edge joist 23 is generated parallel to the joist 21 100 mm inside the enclosing line where the joist 21 is generated.

In step C7, the joist supports generate beams.

In this case, if the joist between the joists that has already been generated from the enclosing line of the upper and lower floors exceeds the pitch set in the automatic generation parameter, the joist support will run straight to the joist at the pitch set in the automatic generation parameter. generate in the direction of

Next, in step C8, floor hiuchikame is generated.

In this case, the floor flint beams are 7II at the outer corner of the perimeter line of the upper floor.
Generate inside the room enclosing line of t or more. However, it does not occur on stairs or atriums within the room area.

In step C9, joist hanging is generated. in this case,
As shown in FIG. 7, the joists 24 are generated so as to be orthogonal to the joists 21 and in contact with the outer circumferential line of the upper floor. Also,
The offset in this case is 100■.

Then, the process proceeds to step CIO, where a corner pole and a ridgepole are generated. In this case, these corner beams and ridgepoles are generated by finding the corners and ridges from the roof device on the floor below.

Next, in step C11, a main building is generated.

In this case, the main building is generated at a reference pitch (horizontal distance) from the roof system and girder line of the floor below.

In step C12, a shed bundle is generated. In this case, the shed bundle is generated at the end of the main building inside the girder line. However, locations where there are pillars on the upper floor at intersections with the outer perimeter line of the upper floor are excluded. Here, if the intersection of the girder line and the purlin, the intersection of the purlin and the beam, the intersection with the general beam, the intersection of the purlin and the beam, and the general beam overlap, the intersection point with the virtual grid 2P from the origin is generated. If the distance between a bunch of sheds or one main building line exceeds 2P, if the distance is 4P, one in the middle (at 2P),
If it is 6P, two lines will be generated at three equal parts (at 2P). Also, if the interval is other than 4P or 6P, 2P from the origin.
generated at the intersection with the virtual grid.

Next, in step C13, a shed bundle receiver is generated. In this case, the shed bundle receiver searches for the same conditions in the minimum range surrounded by beams and general beams for the shed bundles that are not on beams, general beams, or general beams, and surrounds them in the direction where there are many and if the numbers are the same. In the short side direction of the range, and if the side lengths are also the same, then
generated in the direction. Also, if there is no check to see if there are columns on the floor below or beams on the floor in question at both ends of the generated beam, replace the columns between the columns on the floor immediately below in both directions from the intersection with beams. .

Then, in step C14, a shed flint beam is generated.

In this case, the shed flint beams will be placed at the outer corner of the range excluding the outer perimeter of the lower floor from the outer perimeter of the upper floor, and at the inner corner of the room enclosing line of 7 m 2 or more.

In this way, each floor device is created, and the results are displayed on the display device 9.

Next, when creating a shed device on the top floor, when the menu for creating a shed device is selected, the flowchart shown in FIG. 5 is executed by the CPUI.

First, in step D1, the top floor outer circumference line and room area (room enclosing line) are determined from the plan view input in advance, and the process proceeds to step D2, where beams are generated.

In this case, the beam is generated as a general beam from the room enclosing line. However, if a fitting with a width exceeding 2P is input, a beam is generated with the width of that fitting.

Then, in step D3, a ridgepole is generated, and in step D4, a corner beam is generated. In this case, as shown in FIG. 8, the purlin 31 is
The height of both ends of the roof 30 is the same, and the highest place is searched and generated. Further, the corner tree 32 is generated on a side where the roof 30 and another roof overlap, and where the heights of both ends are different.

In step D5, a gable is generated. In this case, the eighth
As shown in the figure, the gable 33 is generated by searching for a line segment of the roof 30 that does not touch other roofs.

In step D6, a main building is generated. In this case, the purlins are generated at a standard pitch (horizontal distance) from the roof device and the girder line.

Next, in step D7, a shed bundle is generated.

In this case, the shed bundle is the end of the purlin inside the girder line, the intersection of the girder line and the purlin, the intersection of the purlin and the beam, the intersection with the general roof, the purlin and the beam,
If the general beam overlaps with the 2P virtual grid from the origin, and if the interval on one of the shed bundles or one main building line exceeds 2P, that interval or 4P.
If it is 6P, generate one in the middle (at 2P), and if it is 6P, generate two at the three equal parts (at 2P). If the interval is other than 4P or 6P, it is generated at the intersection with the virtual grid 2P from the origin.

In step D8, a shed bundle receiver is generated. in this case,
The shed bundle receiver is a beam, a general beam, or a shed bundle that is not mounted on a beam.
Search for the same conditions in the minimum range surrounded by general beams, and generate in the direction with the most number of beams, in the short side of the enclosed area if the number is the same, and in the X direction if the side lengths are also the same. . Also, if you have not checked whether there are pillars from the lower floor or beams from the relevant floor at both ends of the generated beam,
Replace the columns between the columns on the floor immediately below in both directions from that intersection with beams.

Step D9 generates a hut flint beam. in this case,
Hut flint beams will be generated at the outer corner of the perimeter line and the inner corner of the room enclosing line of 7m2 or more.

In step DIO, rafters are generated from the roof device input in advance. In this case, the rafters 34 are generated at a rafter pitch parallel to the flow of the roof 30, as shown in FIG. The rafter pitch here is set by an automatically generated parameter as a value by which side the reference pitch is.

Then, in step Dll, a rafter hook is generated. In this case, as shown in FIG. 9, the rafter hook 35 is located at a predetermined distance (for example, 100 am) from the outer periphery (the position indicated by the broken line in the figure).
to occur.

In this way, the top floor shed device is created, and the result is displayed on the display device 9.

Next, calculate beam formation. In this case, the shed bundle and bundle support are mounted on each beam in the order of height, such as the beam, the shed beam, the pillar, and the floor beam, in descending order of the height of each device created as described above ( (The ends are suspended.) Calculated from the number of pieces and the load index. In this case, the menu load factors are 1 for standard, 3 for snowfall, and 4 for multilingualism.

Therefore, in this way, by using a CAD system, you can input data related to the floor plan and predetermined parameters for automatic generation, and then select the desired menu to create the foundation, each floor, each floor shed, etc. Since it is possible to automatically create a device for creating Buddhist paintings, compared to traditional Buddhist painting creation that relies on manual labor, the work for creating Buddhist paintings can be done easily and in a short time, and it is also less expensive. It can be made inexpensive and economically advantageous.

[Effects of the Invention] The automatic creation device for architectural equipment of the present invention has input means for inputting automatically generated parameters as well as data regarding at least the floor plan of the building, and various control programs necessary for creating Buddhist paintings are stored in advance.
