Description

  The present invention relates to a three-dimensional graphic generation system and a three-dimensional graphic generation method for generating a three-dimensional graphic of a building from a plan view that is a two-dimensional image of the building.

In the process plan in the construction work of high-rise buildings, the cycle process on the standard floor has a great influence on the work schedule, so it is necessary to create the shortest process schedule when starting the construction work. Here, since the structure of each floor of a high-rise building is basically the same, the reference floor indicates a floor having a structure that can be repeatedly formed by the same cycle process when the building is constructed.
In order to carry out the adjustment that minimizes the cycle process, it is necessary to accurately estimate the time for arranging the members on a predetermined floor. The members include at least columns, beams (large beams, small beams), floor slabs, outer wall panels, and the like.

Further, in order to accurately estimate the time for arranging the members, it is necessary to integrate the number of lifting loads that are lifted by using a tower crane or the like to the reference floor. The lifting load refers to a member having a weight that needs to be lifted up to an arrangement place by a tower crane or the like in the above-described columns, beams (large beams, small beams), floor slabs, and outer wall panels.
When only the paper drawings are available, the total number of lifting members is calculated for each type of member so that there is no omission in the confirmation of the members in the plan view of the standard floor printed by the normal operator. Mark while changing the color. Then, the number of members clearly classified by the color marked by the operator is integrated for each type of member.

  The number of members arranged on the reference floor of a building using a computer is automatically performed by a commercially available general-purpose CAD (Computer Aided Design) system and company in-house software. However, when a three-dimensional structure of a building is generated in a CAD system, it is necessary to input many numerical values including the dimension of the member read from the plan view to the CAD system in order to define the three-dimensional data of the member. is there. For example, for general-purpose CAD systems, it is not necessary to accumulate the number of lifts that are carried by lifting a member on a predetermined floor, such as the cross-sectional dimension of the member, the deviation from the core of a column or beam, and the position of a small beam. A numeric value must be entered. It is necessary to read this unnecessary numerical value from the drawing and tentatively determine it in the three-dimensional space of the general-purpose CAD system to generate a three-dimensional structure of the building. It takes time to input numerical values such as member dimensions. As described above, in order to calculate the number of members for the purpose of construction planning, inputting the three-dimensional data of the members takes more time than the operator adds the members using hands and eyes. Is not realistic.

On the other hand, if CAD data used in the CAD system can be obtained as a two-dimensional image data of a design drawing (plan view) that integrates the number of members, the three-dimensional structure of the building can be relatively easily faithful to this design drawing. There is also a system for generating a three-dimensional figure of a building that can be created (see, for example, Patent Document 1).
However, in Patent Document 1, it can be used when a design drawing of a building is obtained as CAD data, but cannot be used when only a plan view printed on paper is supplied. If only the floor plan of the building printed on paper is supplied, as described above, the operator reads the member from the floor plan of the building printed on paper and determines the number of each type of member. It is necessary to add up.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a three-dimensional graphic generation system 1 according to an embodiment of the present invention. In FIG. 1, the three-dimensional graphic generation system 1 includes an input unit 11, an image processing unit 12, a member display unit 13, a member coordinate position detection unit 14, a member placement unit 15, an outer wall line reference point generation unit 16, and an image display unit 17. A member database 18 and an image processing storage unit 19. An input device 2 and a scanner 3 are connected to the three-dimensional graphic generation system 1.

The input unit 11 reads the read image data of the two-dimensional image of the building supplied from the scanner 3, and writes and stores the read image data in the image processing storage unit 19.
The image processing unit 12 reads the read image data from the image processing storage unit 19 and displays it on a display screen (not shown) via the image display unit 17. Then, the image processing unit 12 adjusts the image of the read image data displayed on the display screen by the image display unit 17 based on the control data supplied from the input device 2. The control data is information for performing rotation adjustment so that each of the x axis and the y axis of the plan view of the building in the read image data is parallel to the X axis and the Y axis of the display screen of the image display unit 17. The control data also includes information for performing a scale (enlargement or reduction in the axial direction) with the same scale ratio between the X-axis direction and the Y-axis direction.

  The member display unit 13 includes at least buttons indicating member information of types such as column information, large beam information, small beam information, floor information, and outer wall information as member information used when generating a three-dimensional figure. To display on the display screen. The button indicating the member information is displayed for setting the type of the member to be arranged. For example, when starting a process of generating a three-dimensional figure of a pillar, an operator clicks and selects a pillar information button with a pointing device or the like. And the member display part 13 reads the member table of the member information corresponding to the member selected with the pointing device from the member database 18, and displays it on a display screen.

  Further, the member display unit 13 outputs information (member symbol, that is, member identification information) of the member selected from the member table by the pointing device to the member arranging unit 15. The three-dimensional figure of the building and the three-dimensional figure of the member in the present embodiment are configured in a three-dimensional coordinate system including the X axis, the Y axis, and the Z axis. In this three-dimensional coordinate system, the height direction of the building is constituted by the Z axis, and the floor plane of the building is a two-dimensional plane constituted by the X axis and the Y axis. Each of the X-axis and Y-axis of the two-dimensional plane (two-dimensional plane in the three-dimensional coordinate system) that is the floor plane represents a two-dimensional coordinate system in which a two-dimensional image (plan view) of the building read by the scanner is shown. It corresponds to each of the x-axis and the y-axis that constitute.

  In the plan view of the building displayed on the display screen of the image display device 17, when the operator indicates the position of the member with the pointing device in the input device 2, the member coordinate position detection unit 14 reads the read image data ( The coordinate position of the member in the two-dimensional coordinate system of the (two-dimensional image) is detected. Then, the member coordinate position detection unit 14 outputs the detected coordinate position of the member in the two-dimensional coordinate system to the member placement unit 15.

Deploy. Here, the member placement unit 15 is configured to display a three-dimensional coordinate system (X-axis, Y-axis, and Z-axis) of the display screen corresponding to the coordinate position of the two-dimensional coordinate system (coordinate system including the x-axis and y-axis) of the read image data. A three-dimensional figure of the member is arranged with respect to a coordinate position of a two-dimensional plane (a two-dimensional coordinate system including an X axis and a Y axis) on the axis.
That is, the 3D graphic generation system 1 according to the present embodiment further includes a member table (preliminarily written and stored in the member database 18) indicating the cross-sectional shape of the arrangement member corresponding to the member, as will be described later. .

The member arrangement unit 15 corresponds to the coordinate position of the member in the two-dimensional image of the building, and when arranging the member in the three-dimensional coordinate system of the three-dimensional structure of the building, the member arrangement unit 15 extends the member in the direction perpendicular to the plane of the cross-sectional shape, and arranges the member A member shape having a necessary length (or width) is generated, and a three-dimensional structure of members necessary for the arrangement having the cross-sectional shape is generated.
In the present embodiment, since the height of the reference floor is set in advance to a predetermined value (for example, 4 m), the height in the Z-axis direction is limited by this height. For example, if the member is a pillar, the length of the pillar becomes this predetermined value (for example, 4 m).

  The outer wall line reference point generating unit 16 is a column provided on the outermost periphery of the building with respect to the outer wall line of the building arranged on the two-dimensional plane composed of the x-axis and the y-axis of the three-dimensional space in the three-dimensional figure of the building. Draw a perpendicular from each of the (peripheral columns). Then, the outer wall line reference point generation unit 16 sets the intersection of the outer wall line and the perpendicular drawn on the outer wall line as the outer wall line reference point. Then, the outer wall line reference point generation unit 16 outputs the obtained coordinate position of the outer wall line reference point to the member placement unit 15.

  The image display unit 17 displays a two-dimensional image of a building in which the arrangement of members including at least columns, beams, floor slabs, and outer wall panels is described, that is, read image data of the building (two-dimensional image) on the display screen as shown below. To do. The image display unit 17 displays a three-dimensional figure of the building generated based on the two-dimensional image of the building on the display screen.

  In the member database 18, each of the column table, the large beam table, the small beam table, the floor table, and the outer wall table in which each of the column information, the large beam information, the small beam information, the floor information, and the outer wall information is written is stored in advance. Yes. Further, when there is no necessary member, the operator may be able to input a numerical value input by the keyboard of the input device 2 through the input unit 11.

  FIG. 2 is a diagram illustrating an example of a display image for selecting member information displayed on the display screen by the member display unit 13. In order to select which member to input when generating the three-dimensional figure of the member, the member display unit 13 includes column information, girder information, cantilever type as member information, as shown in FIG. A button for each character of large beam information, small beam information, floor information, and outer wall information is displayed. In addition, the member display unit 13 displays an end button for ending the input of each member beside each of column information, beam information, cantilever type beam information, beam information, floor information, and outer wall information. To do. The member display unit 13 displays a completion button for ending generation of the three-dimensional structure of the building when the input of all the members is completed and the three-dimensional structure of the reference floor is completed.

FIG. 3 is a diagram showing a configuration of a column table that is one of the member tables written and stored in advance in the member database 18. In FIG. 3, in the column table, the column cross-sectional shape (the shape in the plane composed of the X-axis and the Y-axis) and the column cross-sectional dimension are associated with the column symbol (column identification information). Are stored in the member database 18. For example, the column of the column symbol C1 has a square cross-sectional shape, and the dimensions are 1000 (mm) long × 1000 (mm) wide × 32 (mm) thick. Here, the dimensions of the cross section of the column are vertical × horizontal × plate thickness if square, and diameter × plate thickness if circular. The length of the column (the length in the height direction) is not particularly set because it is the height of the reference floor. In addition, in the column table, data of columns of a plurality of dimensions generally used is written and stored in advance.
When the column information is selected by the pointing device in the button column of the member information shown in FIG. 2, the member display unit 13 reads the column table shown in FIG. 3 from the member database 18 and displays it on the display screen.

FIG. 4 is a diagram showing a configuration of a girder table that is one of the member tables written and stored in advance in the member database 18. In FIG. 4, the girder table corresponds to a girder symbol (girder identification information), and a cross-sectional shape of the girder (in many cases, a shape in a plane composed of the X axis and the Z axis, or the Y axis and the Z axis), The dimensions of the large beam are associated with each other and stored in the member database 18. For example, the girder of the girder symbol G1 has an H-shaped cross section, and the dimensions are (height) 1000 (mm) x width 300 (mm) x web thickness 25 (mm) x flange thickness 32 ( mm). Here, the dimension is a dimension of a cross section in a plane perpendicular to the major axis direction of the large beam, and is, for example, the formation (height), width, web thickness, and flange thickness of the steel frame to be the large beam. Since the length is the distance between the columns to be arranged, no particular setting is made. In addition, data of large beams having a plurality of dimensions generally used is written and stored in the large beam table in advance.
When the beam information is selected by the pointing device in the member information button row shown in FIG. 2, the member display unit 13 reads the beam table shown in FIG. 4 from the member database 18 and displays it on the display screen.

FIG. 5 is a diagram showing the configuration of a beam table, which is one of the member tables previously written and stored in the member database 18. In FIG. 5, the beam table corresponds to the beam symbol (beam identification information), and the cross-sectional shape of the beam (in many cases, in the plane composed of the X axis and the Z axis, or the Y axis and the Z axis). Shape) and the dimensions of the beam are associated with each other and stored in the member database 18. For example, the small beam of the small beam symbol B1 has an H-shaped cross section, and the dimensions are (height) 400 (mm) × width 300 (mm) × web thickness 8 (mm) × flange thickness. 13 (mm). Here, the dimension is a dimension of a cross section in a plane perpendicular to the major axis direction of the small beam, for example, the formation (height), width, web thickness, and flange thickness of the steel frame that forms the small beam. Since the length is the distance between the arranged beams, no particular setting is made. In addition, in the beam table, data of beam beams having a plurality of dimensions generally used are written and stored in advance.
Further, when the beam information is selected by the pointing device in the member information button row shown in FIG. 2, the member display unit 13 reads out the beam table shown in FIG. 5 from the member database 18 and displays it on the display screen. .

FIG. 6 is a diagram showing the configuration of a floor table that is one of the member tables written and stored in advance in the member database 18. In FIG. 6, the floor table is prewritten and stored in the member database 18 in association with the floor slab type corresponding to the floor symbol (floor identification information). For example, the floor slab of the small beam symbol S1 is a floor using a flat deck. A predetermined value is set for the thickness of the floor slab, for example, 200 mm. The floor table stores data of a plurality of types of floor slabs that are generally used in advance.
When the floor information is selected by the pointing device in the member information button row shown in FIG. 2, the member display unit 13 reads the floor table shown in FIG. 6 from the member database 18 and displays it on the display screen.

FIG. 7 is a diagram showing a configuration of an outer wall table that is one of the member tables written and stored in advance in the member database 18. In FIG. 7, the type and dimension of the outer wall panel as the outer wall are associated with the outer wall symbol (outer wall identification information), and are written and stored in advance in the member database 18. For example, the outer wall panel of the outer wall symbol OW1 is a pot window type PC (Precast Concrete) plate and has a thickness of 200 mm. This outer wall table shows the thickness of the outer wall panel as a dimension. Depending on the main part of the outer wall panel, more values may be indicated as the dimensions of the outer wall table. The height of the outer wall panel is not particularly set because it is the height of the reference floor. The width of the outer wall panel is not particularly set because it is determined from the interval between the outer wall line reference points and the number of assigned panels. The outer wall table stores data of outer wall panels of a plurality of types and sizes that are generally used.
When the outer wall information is selected by the pointing device in the member information button row shown in FIG. 2, the member display unit 13 reads the outer wall table shown in FIG. 7 from the member database 18 and displays it on the display screen.

  Returning to FIG. 1, the image processing storage unit 19 stores the read image data supplied from the scanner 3 and the three-dimensional structure of the building formed based on the read image data.

Next, the operation of the 3D graphic generation system 1 according to the present embodiment will be described with reference to the drawings. FIG. 8 is a flowchart illustrating a processing example of 3D graphic generation in the 3D graphic generation system 1 according to the present embodiment.
Step S11:
The operator uses the scanner 3 to read a plan view of the building printed on the paper. Thereby, the scanner 3 outputs the read plan view of the building to the three-dimensional graphic generation system 1 as read image data that is a two-dimensional image.
The input unit 11 writes and stores the read image data supplied from the scanner 3 in the image processing storage unit 19.

Step S12:
The image processing unit 12 reads the read image data from the image processing storage unit 19. Then, the image processing unit 12 displays the read image data that has been read on the display screen via the image display unit 17.
The worker visually recognizes the read image data displayed on the display screen of the image display unit 17 of the three-dimensional graphic generation system 1.
When the worker recognizes that the x-axis and y-axis of the plan view of the building are deviated from the X-axis and Y-axis in the coordinate system of the display screen in the displayed read image data, the following work is performed. I do.

  That is, the operator makes each of the x-axis and y-axis in the plan view parallel to the X-axis and Y-axis in the coordinate system of the display screen. Select parallel to x-axis). Then, the operator inputs an instruction to rotate the read image of the building from the input device 2. When this rotation processing information is supplied via the input unit 11, the image processing unit 12 rotates the read image of the building so that the selected line segment is parallel to the X axis. Thereby, each of the x-axis and the y-axis in the plan view is adjusted by the image processing unit 12 in parallel with the X-axis and the Y-axis in the coordinate system of the display screen. As the line segment to be selected, for example, a line as shown in the plan view is used. As a result, when generating a three-dimensional figure, it is possible to prevent the axis from being shifted on the display screen and making the member arrangement process difficult.

Further, the operator is parallel to each of the x-axis and y-axis in the plan view and the X-axis and Y-axis in the coordinate system of the display screen, but the scale in the x-axis direction and the y-axis direction in the plan view. If it is recognized that is not 1: 1, the following operations are performed.
That is, for each of the x-axis and y-axis in the plan view, the operator selects a straight end point whose length is known, and the distance (length) between the coordinates of the end point on the X-axis and the Y-axis Enter the distance between the coordinates of the endpoints above. Then, an instruction is input from the input device 2 by the worker to perform the process of adjusting the scale. As a result, the image processing unit 12 scales the coordinates on the X and Y axes so that the distance between the coordinates of the endpoints on the X axis and the distance between the coordinates of the endpoints on the Y axis are the input distances. Are adjusted to be the same. That is, a square is displayed as a square with an aspect ratio of 1: 1.

  FIG. 9 is a diagram illustrating the image processing operation performed by the image processing unit 12. FIG. 9A shows that the x-axis and the X-axis are shifted by an angle θ. If the x-axis and the y-axis are orthogonal, the y-axis and the Y-axis are similarly shifted by the angle θ. FIG. 9A shows that the passing line 101 is selected at the designated point A and the designated point B. In FIG. 9A, the passage line 101 is parallel to the x-axis and is inclined by the angle θ with respect to the X-axis (line segment 102) as described above. When the image processing unit 12 performs the rotation process, the angle θ is set to “0”, the x axis and the X axis are parallel, and the coordinate system of the plan view matches the coordinate system of the display screen.

FIG. 9B shows processing for setting the scale in the x-axis direction and the y-axis direction to 1: 1 because the scale in the x-axis direction and the y-axis direction is not 1: 1. That is, the points C and D where the distance between the coordinates is clearly known are selected on the x-axis of the plan view on the display screen. In addition, on the y axis of the plan view on the display screen, the points D and E where the distance between the coordinates is clearly known are selected. Then, when an instruction to perform the process of adjusting the scale is input, the image processing unit 12 is configured such that the distance between the coordinates of the end points on the x axis and the distance between the coordinates of the end points on the y axis are the input distances. Is adjusted so that the scale of coordinates in each of the x-axis and the y-axis is the same, that is, 1: 1.
FIG. 9C is a diagram showing that the x-axis and the y-axis are parallel to the X-axis and the Y-axis, respectively, and the scale ratio of the x-axis and the y-axis is 1: 1.

Step S13:
Next, in the two-dimensional image of the building displayed on the display screen of the image display unit 17, the operator inputs an outer wall line (floor end line) having a predetermined distance from the outermost shell of the building to the input device. Draw as a polygon (set of line segments) with the pointing device in 2. The image processing unit 12 displays the outer wall line on the display screen of the image display unit 17 using the coordinate position of the end point of the line segment in the two-dimensional coordinate system input via the input unit 11. Further, the image processing unit 12 draws and stores the coordinate in the coordinate system of the three-dimensional figure in correspondence with the coordinate position of the coordinate system of the input two-dimensional image. At this time, the image processing unit 12 sets the height of the outer wall line to the height of the reference floor.

  FIG. 10 is a diagram for explaining the generation of an outer wall line located in the outermost shell (the end portion of the floor slab) of the building in the plan view. In FIG. 10, a set of line segments indicating the outermost shell of the building is an outer wall line 201. For example, the operator inputs the coordinates of the outer wall line intersection 203 along the outermost shell of the building using a pointing device in the input device 2. Thereby, the image processing unit 12 draws the outer wall line 201 by connecting the outer wall line intersections 203 to generate a polygonal outer wall line 201 surrounding the outermost shell of the building. In FIG. 10, an outer wall line reference point 202 is an intersection of a perpendicular line dropped from the outer peripheral column center 203 </ b> T, which is the center of the outermost peripheral column 203, to the outer wall line 201 and the outer wall line 201.

Step S14:
Here, the member display unit 13 displays a member selection button shown in FIG. 2 for selecting the type of the member to be input on the display screen of the image display unit 17.
Then, the operator clicks a selection button in which column information indicating a column is entered as the type of member to be input from the member selection buttons displayed on the display screen of the image display unit 17 (the display screen is a pointing device). Press).
As a result, the input device 2 outputs information indicating that the column has been selected as a member to the member display unit 13 via the input unit 11.

Next, when notified that the column information selection button has been selected, the member display unit 13 reads column table data from the member database 18. The member display unit 13 displays the read column table (see FIG. 3) on the display screen of the image display unit 17.
When the column table is displayed on the display screen of the image display unit 17, the operator selects a column to be input from the displayed column table based on the cross-sectional shape and dimensions, and selects, for example, a column symbol display area using a pointing device. .
When the display area is selected, the member display unit 13 outputs (notifies) the column symbol selected as information indicating which column is selected to the member placement unit 15.

Then, when the column symbol is notified from the member display unit 13, the member arranging unit 15 reads the column cross-sectional shape and the dimension indicated by the notified column symbol from the column table of the member database 18.
Next, the operator clicks the column image corresponding to the selected column in the two-dimensional image of the building with the pointing device in order to arrange the selected column.
Thereby, the input device 2 detects the clicked coordinate position in the coordinate system of the two-dimensional image, and outputs the detected coordinate position to the member placement unit 15 via the input unit 11.

When the coordinate position of the two-dimensional image of the column is notified, the member arranging unit 15 3 of the column 203 (see FIG. 10) with respect to the coordinate system coordinate position of the three-dimensional figure corresponding to the coordinate position of the two-dimensional image. Place a dimensional figure. Here, the member arrangement unit 15 uses the data of the cross-sectional shape of the column read from the column table, and generates the shape of the column 203 having a three-dimensional figure with the height (length) as the height of the reference floor.
Each time the operator selects an image of a pillar of the 2D image of the building with the pointing device, the coordinates of the coordinate system of the 3D figure corresponding to the coordinate position of the coordinate system of the selected 2D image as described above. A 3D figure of a pillar is generated for the position.

Step S15:
Next, the member display unit 13 determines whether or not an end button adjacent to the column information button is selected in the selection button for selecting a member to be input displayed on the display screen of the image display unit 17. That is, it is detected whether or not the input of the pillar has been completed.
At this time, when the end button adjacent to the column information button is selected, the member display unit 13 advances the process to step S16. On the other hand, if the end button adjacent to the column information button is not selected, the member display unit 13 advances the process to step S14 and continues the process of generating the three-dimensional figure of the column 203.
Further, when another column symbol in the column table on which the operator is displayed is selected by the pointing device, a three-dimensional figure of the column generated thereafter is generated based on the newly selected column cross-sectional shape.

Step S16:
Next, when the input of the pillar 203 is completed, for example, when the pillar 203 is placed within a certain distance (for example, 2 m) from the outer wall line 201, the member placement unit 15 faces the outer wall line 201 to Rearrange the columns 203 within a certain distance. That is, the member placement unit 15 adjusts the coordinate position of the outer peripheral pillar center 203T in each pillar 203 so that the pillar 203 placed in the outermost shell of the building is parallel to the opposing outer wall line 201. For example, the member placement unit 15 uses the distance of each perpendicular line 204 drawn from the pillar 203 disposed opposite to each outer wall line 201 to the outer wall line 201 to calculate the reference distance from the outer wall line by the least square method. Ask for.

And the member arrangement | positioning part 15 moves each pillar 203 along the corresponding perpendicular line so that it may become the calculated | required reference distance, and rearranges the pillar 203. FIG. Here, by adjusting the arrangement according to the coordinate positions of the plurality of columns 203 facing each outer wall line 201, it is possible to reduce an input error when selecting a column image in a two-dimensional image.
Thereby, only the outermost shell (outermost circumference) column 203 can be arranged in parallel to the opposing outer wall line 201.

Step S17:
Next, the input device 2 outputs information indicating that the member to be arranged next is a large beam to the member display unit 13 via the input unit 11 in the order of the members of the selection buttons for selecting the member.
When the member display unit 13 is notified that the selection button for the beam information has been selected, the member display unit 13 reads the beam data from the member database 18. Then, the member display unit 13 displays the read girder table (see FIG. 4) on the display screen of the image display unit 17.
When the girder table is displayed on the display screen of the image display unit 17, the operator selects a girder desired to be input from the displayed girder table from the cross-sectional shape and dimensions, and for example, selects the display area of the girder symbol with a pointing device. .
When the display area is selected, the member display unit 13 outputs (notifies) the selected beam symbol as information indicating which beam is selected to the member placement unit 15.

Then, when the large beam symbol is notified from the member display unit 13, the member arranging unit 15 reads the cross-sectional shape and dimensions of the large beam indicated by the notified large beam symbol from the large beam table of the member database 18.
Next, the operator clicks the image of the large beam corresponding to the selected large beam in the two-dimensional image of the building with the pointing device in order to arrange the selected large beam.
Thereby, the input device 2 detects the clicked coordinate position in the coordinate system of the two-dimensional image, and outputs the detected coordinate position to the member placement unit 15 via the input unit 11.

When the coordinate position of the two-dimensional image is notified, the member placement unit 15 is closest to the vicinity of the coordinate position in the coordinate system of the three-dimensional figure corresponding to the coordinate position of the two-dimensional image (for example, within 5 m from the coordinate position). The column 203 at is searched.
Next, the member arrangement unit 15 uses the center of the searched column as a center, sets a predetermined distance (for example, 15 m) as a radius, and +/- with respect to a line segment connecting the center of the column 203 and the clicked coordinate position. Draw an arc with an angle of -20 ° to generate a sector-shaped detection area.

The member placement unit 15 detects the pillar 203 closest to the pillar 203 located at the center of the sector from the pillars 203 included in the generated detection area.
Then, the member arranging unit 15 generates a three-dimensional figure of the large beam 206 having a cross-sectional shape read from the large beam table, and generates the large beam 206 generated between the column 203 located at the center of the fan shape and the detected column 203. The three-dimensional figure is arranged. At this time, the member placement unit 15 is configured such that the top end (uppermost surface) of the girder 206 has a predetermined numerical value (the thickness of the floor slab (slab thickness) to be placed later) from the floor height (floor height), For example, it is arranged at a position lower by 20 cm.

FIG. 11 is a diagram for explaining the arrangement processing of large beams arranged between the pillars 203 of the building in the plan view. In FIG. 11, a coordinate position 210 is a coordinate position in a coordinate system of a three-dimensional figure corresponding to the coordinate position selected by the operator in the two-dimensional image of the building. The member placement unit 15 detects the nearest column 203A within the radius 5 m (first distance) of the coordinate position 210. Then, the member placement unit 15 has a predetermined length (for example, 15 m, a second longer than the first distance) with respect to the line 215 connecting the center of the column 203A and the coordinate position 210 with the center of the column 203A as the center. A sector-shaped region 250 is generated by drawing an arc with a radius of ()) and a central angle θ = + / − 20 °.
The member placement unit 15 detects the column 203B that is included in the generated region 250 and is closest to the column 203A. And the member arrangement | positioning part 15 arrange | positions the big beam 206 between the pillar 203A and the pillar 203B.

Step S18:
Next, the member display unit 13 determines whether or not the end button adjacent to the large beam information button is selected in the selection button for selecting the input member displayed on the display screen of the image display unit 17. That is, it is detected whether or not the input of the large beam is completed.
At this time, when the end button adjacent to the side of the large beam button is selected, the member display unit 13 advances the process to step S19. On the other hand, when the end button adjacent to the side of the large beam information button is not selected, the member display unit 13 advances the process to step S <b> 17 and continues the process of generating the three-dimensional graphic of the large beam 206.
Further, when another girder symbol in the girder table on which the operator is displayed is selected by the pointing device, the three-dimensional figure of the girder generated thereafter is generated by the cross-sectional shape of the newly selected girder.

Step S19:
Next, the input device 2 sends information indicating that the member to be arranged next is a cantilever-type large beam to the member display unit 13 via the input unit 11 from the order of the members of the selection buttons for selecting the member. Output.
When the member display unit 13 is notified that the cantilever type beam selection button has been selected, the member display unit 13 reads the beam table data from the member database 18. Then, the member display unit 13 displays the read girder table (see FIG. 4) on the display screen of the image display unit 17.
When the girder table is displayed on the display screen of the image display unit 17, the operator selects a girder desired to be input from the displayed girder table from the cross-sectional shape and dimensions, and for example, selects the display area of the girder symbol with a pointing device. .
When the display area is selected, the member display unit 13 outputs (notifies) the selected beam symbol as information indicating which beam is selected to the member placement unit 15.

Then, when the large beam symbol is notified from the member display unit 13, the member arranging unit 15 reads the cross-sectional shape and dimensions of the large beam indicated by the notified large beam symbol from the large beam table of the member database 18.
Next, the operator clicks the image of the large beam corresponding to the selected large beam in the two-dimensional image of the building with the pointing device in order to arrange the selected large beam. At this time, a coordinate position on the large beam that is not so far away (for example, within 5 m) from the column 203 to which the large beam is connected is clicked with a pointing device.
Thereby, the input device 2 detects the clicked coordinate position in the coordinate system of the two-dimensional image, and outputs the detected coordinate position to the member placement unit 15 via the input unit 11.

When the coordinate position of the two-dimensional image is notified, the member placement unit 15 is in the vicinity of the coordinate position in the coordinate system of the three-dimensional figure corresponding to the coordinate position of the two-dimensional image (for example, within 5 m centered on the coordinate position). The nearest column 203 is searched for.
The member arrangement unit 15 sets the searched column 203 as a column on which the cantilever type large beam 206 is arranged, and connects one end of the large beam 206 to the searched column 203.
Next, the operator clicks the coordinate position at which the other end of the large beam 206 not connected to any column ends on the display screen of the image display unit 17 with a pointing device.
Thereby, the input device 2 detects the clicked coordinate position in the coordinate system of the two-dimensional image, and outputs the detected coordinate position to the member placement unit 15 via the input unit 11.

When the coordinate position of the two-dimensional image is notified, the member arranging unit 15 sets the coordinate position in the coordinate system of the three-dimensional figure corresponding to the coordinate position of the two-dimensional image as the coordinate position at the other end.
As described above, the member placement unit 15 places the cantilever-type large beam 206 with respect to the column 203. That is, the member placement unit 15 generates a three-dimensional figure of the girder 206 based on the cross-sectional shape read from the girder table between the detected one column 203 and the clicked coordinate position. At this time, the member placement unit 15 is configured such that the top end (uppermost surface) of the girder 206 has a predetermined numerical value (the thickness of the floor slab (slab thickness) to be placed later) from the floor height (floor height), For example, it is arranged at a position lower by 20 cm.

  Alternatively, for a large beam extending from the column 203 toward the outside of the building, a cantilever type large beam may be arranged between the column 203 and an outer wall line reference point determined by a perpendicular line extending from the column 203 to the outer wall line. good. When a beam is arranged with a large span (interval) that cannot be found by a member search or a member search, it is input to click two coordinate points in a two-dimensional image.

Step S20:
Next, the member display unit 13 determines whether or not an end button adjacent to the button is selected in the selection button for selecting a member to be input displayed on the display screen of the image display unit 17, that is, It detects whether or not the input of the cantilever type girder has been completed.
At this time, if the end button adjacent to the button of the cantilever type large beam information is selected, the member display unit 13 advances the process to step S21.

On the other hand, if the end button adjacent to the cantilever type large beam information button is not selected, the member display unit 13 proceeds to step S19 and continues the generation process of the three-dimensional figure of the cantilever type large beam.
In addition, when the operator selects another large beam symbol with the pointing device in the displayed girder table, a 3D figure of a column generated thereafter is newly generated by the girder having a cross-sectional shape selected by the operator. .

Step S21:
Next, the input device 2 outputs information indicating that the member to be arranged next is a small beam to the member display unit 13 via the input unit 11 in the order of the members of the selection buttons for selecting the member. .
When the member display unit 13 is notified that the beam beam selection button has been selected, the member display unit 13 reads the beam table data from the member database 18. Then, the member display unit 13 displays the read beam table (see FIG. 5) on the display screen of the image display unit 17.
When the girder table is displayed on the display screen of the image display unit 17, the operator selects a girder to be input from the displayed girder table from the cross-sectional shape and dimensions, and for example, points the display area of the girder symbol. Select by device.
When the display area is selected, the member display unit 13 outputs (notifies) the selected beam symbol as information indicating which beam is selected to the member placement unit 15.

Then, when the small beam symbol is notified from the member display unit 13, the member arranging unit 15 reads the cross-sectional shape and dimensions of the small beam indicated by the notified small beam symbol from the small beam table of the member database 18.
Next, in order to arrange the selected beam, the operator clicks the image of the beam corresponding to the selected beam in the two-dimensional image of the building with a pointing device. At this time, a position on the small beam that is not far away (for example, within 2 m) from the large beam to which the small beam is connected or another small beam already arranged is clicked by the pointing device.
Thereby, the input device 2 detects the clicked coordinate position in the coordinate system of the two-dimensional image, and outputs the detected coordinate position to the member placement unit 15 via the input unit 11.

When the coordinate position of the two-dimensional image is notified, the member arranging unit 15 is in the vicinity of the coordinate position in the coordinate system of the three-dimensional figure corresponding to the coordinate position of the two-dimensional image (for example, the distance about the coordinate position is 2 m). Within)) the nearest large beam 206 or small beam is searched.
The member arranging unit 15 uses the searched large beam 206 or small beam as a partner to which one end of the small beam is connected when a new small beam is arranged.
Then, the member placement unit 15 detects a large beam or a small beam within a predetermined distance (for example, 8 m) from one end of the small beam, and detects the detected large beam or small beam in addition to the small beam to be newly disposed. Assume that the end is connected.

The member placement unit 15 has coordinates clicked between a large beam or a small beam to which one end of a newly arranged small beam is connected and a large beam or a small beam to which the other end of the newly arranged small beam is connected. Place a new beam to pass through the position. At this time, the newly arranged small beam is connected at right angles to the large beam or small beam closer to the clicked coordinate position.
Thereby, the member arrangement | positioning part 15 produces | generates the three-dimensional figure of a small beam by the cross-sectional shape read from the small beam table between the two detected large beams or small beams. At this time, as in the case of the large beam 203, the member arrangement unit 15 has a predetermined numerical value (the thickness of the floor slab to be arranged later) from the floor height (floor height) of the top end (top surface) of the small beam. (Slab thickness), for example, 20 cm) is placed at a lower position.

FIG. 12 is a diagram for explaining an arrangement process of a small beam newly arranged between a large beam or a small beam of a building and another large beam or another small beam in the plan view. In FIG. 12, a large beam 206A is disposed between a column 203A and a column 203B. A large beam 206E is disposed between the column 203C and the column 203D. A large beam 206B is disposed between the column 203B and the column 203D. A large beam 206C is disposed between the column 203B and a column (not shown). Similarly, a large beam 206D is disposed between the column 203D and a column (not shown). A small beam 207B is disposed between the large beam 206A and the large beam 206E. A small beam 207D is disposed between the large beam 206C and the large beam 206D. A large beam 206G is disposed between the column 203A and the column 203C.
In FIG. 12, each of the coordinate positions 221, 222, and 223 is a coordinate position in the coordinate system of the three-dimensional figure corresponding to the coordinate position selected by the operator in the two-dimensional image of the building.

First, a process for arranging the small beam 207A between the large beam 206A and the large beam 206E will be described.
The member placement unit 15 detects the large beam 206A located within a distance of 2 m from the coordinate position 221 as a partner to which one end of the clicked coordinate position 221 is connected.
Next, the member placement unit 15 generates a small beam 207A whose one end is connected to the connection point 225 at a right angle to the large beam 206A through the coordinate position 221.
Moreover, the member arrangement | positioning part 15 connects the other end of the small beam 207A to the connection point 226 in the large beam 206E within a predetermined distance (for example, 8 m) from the connection point 225. Thereby, the member placement unit 15 places the small beam 207A between the connection point 225 of the large beam 206A and the connection point 226 of the large beam 206E.

Next, a process for arranging the small beam 207C between the large beam 206B and the already arranged small beam 207B will be described.
The member placement unit 15 detects the small beam 207 </ b> B located within a distance of 2 m from the coordinate position 222 as a partner to which one end of the small beam passing through the clicked coordinate position 222 is connected.
Next, the member placement unit 15 generates a beam 207C having one end connected to the connection point 227 at a right angle to the beam 207B through the coordinate position 222.
In addition, the member placement unit 15 connects the other end of the small beam 207C to the connection point 228 in the large beam 206B within a predetermined distance (for example, 8 m) from the connection point 227. Accordingly, the member arranging unit 15 arranges the small beam 207C between the connection point 227 of the small beam 207B and the B connection point 228 of the large beam 206.

Next, a process for arranging the small beam 207E between the large beam 206B and the already arranged small beam 207D will be described.
The member arranging unit 15 detects the small beam 207D located within a distance of 2 m from the coordinate position 223 as a partner to which one end of the small beam passing through the clicked coordinate position 223 is connected.
Next, the member placement unit 15 generates a beam 207E having one end connected to the connection point 229 at a right angle to the beam 207D through the coordinate position 223.
Moreover, the member arrangement | positioning part 15 connects the other end of the small beam 207E to the connection point 230 in the large beam 206B which exists within a predetermined distance (for example, 8 m) from the connection point 229. Thereby, the member placement unit 15 places the small beam 207E between the connection point 229 of the small beam 207D and the connection point 230 of the large beam 206B.

Step S22:
Next, the member display unit 13 determines whether or not the end button adjacent to the small beam information button is selected in the selection button for selecting the input member displayed on the display screen of the image display unit 17. That is, it is detected whether or not the input of the beam is finished.
At this time, the member display unit 13 advances the process to step S23 when the end button adjacent to the side of the button of the beam information is selected. On the other hand, when the end button displayed adjacent to the large beam information button is not selected, the member display unit 13 advances the process to step S21 to execute the small beam (for example, the small beam from the small beam 207A in FIG. 12). The generation process of the three-dimensional figure of the beam 207E etc. is continued.
In addition, when another beam symbol in the beam table displayed by the operator is selected by the pointing device, the 3D figure of the beam generated thereafter is generated by the cross-sectional shape of the newly selected beam. The

Step S23:
Next, the outer wall line reference point generation unit 16 is within a predetermined fixed distance (for example, 2 m) from the outer wall line 201 in the two-dimensional plane (two-dimensional coordinate system including the X axis and the Y axis) of the three-dimensional figure of the building. The column 203 (see FIG. 10, for example) is detected as an outer peripheral column.
Then, the outer wall line reference point generation unit 16 draws a perpendicular line 204 to the opposing outer wall line 201 from the outer peripheral column existing in the vicinity of the outermost peripheral side of the building facing the outer wall line 201. The outer wall line reference point generation unit 16 sets the intersection of the perpendicular line 204 and the outer wall line 201 as the outer wall line reference point 202.

At this time, when the vertical line 204 does not intersect with the corresponding external wall line 201, the external wall line reference point generation unit 16 ignores the vertical line. For example, in FIG. 10, a vertical line is drawn from the outer peripheral column 203A on the extension line 201B of the outer wall line 201A, but the extension line 201B does not actually have a line and does not intersect with the vertical line from the outer peripheral column 203A. The outer wall line reference point 202 cannot be formed.
For this reason, the outer wall line reference point generation unit 16 deletes (ignores) the perpendicular line 204 that does not intersect the outer wall line 201 even within a certain distance.

Step S24:
Next, when the operator confirms that the outer wall line reference point 202 has been formed on the display screen of the image display unit 17, the operator clicks the inner floor information with a pointing device using a selection button for selecting a member to be input. select.
Then, the input device 2 outputs information indicating that the floor slab is selected as the member of the inner floor to the member display unit 13 via the input unit 11.
When notified that the inner floor information selection button has been selected, the member display unit 13 reads the data of the floor table from the member database 18. The member display unit 13 displays the read floor table (see FIG. 6) on the display screen of the image display unit 17.

When the floor table is displayed on the display screen of the image display unit 17, the operator selects a floor slab to be input from the displayed floor table from the type, and selects, for example, a display area of the floor symbol using a pointing device.
By selecting the display area, the member display unit 13 arranges the information indicating that the floor symbol selected as the information indicating which floor slab is selected as the inner floor and the information indicating that the arrangement target is the inner floor. The information is output (notified) to the unit 15.

  The member arrangement unit 15 arranges the selected floor slab in a three-dimensional figure of a building in a polygonal (mostly quadrangular) planar area surrounded by the large beam core and the small beam core. At this time, the member arrangement | positioning part 15 produces | generates the three-dimensional figure of a floor slab as the shape which extruded the part for thickness of the floor slab to the perpendicular direction. Moreover, the member arrangement | positioning part 15 will arrange | position a floor slab with respect to all the polygons enclosed by the large beam core and the small beam core. For this reason, a floor slab will be arrange | positioned also in the area | region where a floor slab is not actually arrange | positioned. For example, the floor slab arranged in an area where the floor slab is not arranged such as an elevator shaft or a blow-off is manually deleted by the operator. Here, the girder core is the center line of the girder in the plan view. The beam core is the center line of the beam in the plan view.

Step S25:
Next, when the operator confirms that the outer wall line reference point 202 has been formed on the display screen of the image display unit 17, the operator clicks the outer floor information with a pointing device at a selection button for selecting a member to be input. select.
Then, the input device 2 outputs information indicating that the floor slab is selected as the member of the outer floor to the member display unit 13 via the input unit 11.
When notified that the outer floor information selection button has been selected, the member display unit 13 reads the data of the floor table from the member database 18. The member display unit 13 displays the read floor table (see FIG. 6) on the display screen of the image display unit 17.

When the floor table is displayed on the display screen of the image display unit 17, the operator selects a floor slab to be input from the displayed floor table from the type, and selects, for example, a display area of the floor symbol using a pointing device.
When the display area is selected, the member display unit 13 uses information indicating that the selected floor symbol and the arrangement target are the outer floor as information indicating which floor slab is selected as the outer floor. Output (notify) to the placement unit 15.

The member placement unit 15 includes a line segment connecting the selected outer wall line reference point 202 to the adjacent floor slab, a perpendicular line (line segment) extending from the outer peripheral column to the outer wall line, and a line segment representing the core of the large beam / small beam. One sheet is arranged for each polygonal area as a side. At this time, the member arrangement | positioning part 15 produces | generates the three-dimensional figure of a floor slab as the shape which extruded the part for thickness of the floor slab to the perpendicular direction.
In addition, the member placement section 15 includes a line segment connecting the outer wall line reference point 202, a perpendicular line (line segment) extending from the outer peripheral column to the outer wall line, and a line segment representing the core of the large beam / small beam surrounded by the sides. The floor slab is placed against the polygon. For this reason, a floor slab will be arrange | positioned also in the area | region where a floor slab is not actually arrange | positioned. As in the case of the inner floor, the floor slab arranged in the area where the floor slab is not arranged is manually deleted by the operator.

FIG. 13 is a diagram illustrating a process of arranging the floor slab selected by the operator on the floor of the building. In FIG. 13, the intersection of the perpendicular line 204 from the outer peripheral column 203 </ b> A and the outer wall line 201 is an outer wall line reference point 202. Further, the intersection point of the outer wall lines 201 is a corner point 240.
The member placement unit 15 places the floor slab in a rectangular area 501 surrounded by the large beam 206 (that is, the column 203 is a vertex) as the floor slab placement process of the inner floor.

Further, the member placement unit 15 performs a square area 502 having apexes of the outer peripheral column 203A and the outer wall line reference point 202, an outer peripheral column 203A, and the outer wall line reference point 202 as an arrangement process of the outer floor slab (balcony floor). The floor slab selected by the operator is placed in a polygonal region 503 having the corner point 240 as a vertex.
Here, the member arrangement | positioning part 15 arrange | positions a floor slab also to the area | region 504 where a floor slab is not actually arrange | positioned. This region 504 is a region where a floor slab is not disposed on the structure, such as an elevator shaft or a blow-through. The floor slab arranged in the area where the floor slab is not arranged is manually deleted by the operator.

Step S26:
Next, when the operator confirms that the outer wall line reference point 202 has been formed on the display screen of the image display unit 17, the user clicks and selects the outer wall information with a pointing device using a selection button for selecting an input member. To do.
Then, the input device 2 outputs information indicating that the outer wall panel has been selected as a member to the member display unit 13 via the input unit 11.
When notified that the outer wall information selection button has been selected, the member display unit 13 reads the data of the outer wall table from the member database 18. Then, the member display unit 13 displays the read outer wall table (see FIG. 7) on the display screen of the image display unit 17.

When the outer wall table is displayed on the display screen of the image display unit 17, the operator selects an outer wall panel to be input from the displayed outer wall table based on the type and size, and for example, selects a display area of the outer wall symbol with a pointing device. .
When the display area is selected, the member display unit 13 outputs (notifies) the selected outer wall symbol to the member placement unit 15 as information indicating which outer wall has been selected.
Further, the operator inputs the number of divisions of the outer wall panel using the input device 2. The number of divisions of the outer wall panel indicates the number of outer wall panels arranged between the columns, that is, between the columns.

On the outer wall line 201, a range in which the selected outer wall panel is arranged is set. For example, the range may be set by any method, such as selecting a plurality of points by clicking between the outer wall line reference points 202 to be arranged with a pointing device, or specifying a range by dragging.
And the member arrangement | positioning part 15 arrange | positions an outer wall panel in the division | segmentation number unit set for every range pinched | interposed by the outer wall line reference | standard point 202 along an outer wall line 201. FIG. Here, the member placement unit 15 generates a three-dimensional figure of the outer wall panel between the two detected pillars 203 based on the cross-sectional shape read from the outer wall table.

Step S27:
