[0044] FIG. 1 is a system configuration diagram of a design support system S related to this embodiment.

[0045] The design support system S related to the present embodiment is mainly composed of the server computer 11 of the office 1, the construction design computer 21 of the construction design 2, and the business office computer 31 of the business office 3.

[0046] In addition, although the construction design 2 and the business office 3 and the office 1 are constituted as separate departments in this embodiment, they may be constituted as the same department.

[0047] The so-called office 1 is a department of a general housing construction manufacturer and seller, and it comprehensively performs housing-related businesses such as ordering, sales, and construction of housing and housing-related products.

[0048] In addition, the so-called construction design 2 is placed in the department of a general residential building manufacturer and seller, and is a department that performs graphic production such as design drawings.

[0049] In addition, the so-called business office 3 is a department arranged in a general housing construction manufacturer and seller, and is a department that actually communicates with customers and accepts orders for houses and the like from customers.

[0050] In addition, in this embodiment, although the office 1 and the business office 3 are constituted as divisions within a general housing construction manufacturer and seller, they can also be constituted as a practitioner commissioned by a housing construction manufacturer and seller, and the construction design can be designed 2Constituted as an external organization such as a design office.

[0051] The office 1 is provided with a server computer 11 as a design drawing management device that comprehensively manages each data in the design support system S of the present embodiment.

[0052] The server computer 11 connects the construction design computer 21 installed in the construction design 2 as a construction design drawing production and transmission device and the business office computer 31 installed in the business office 3 as a suggested design transmission device through the Internet line 13.

[0053]The information determined at the contract stage, such as the proposed design drawing, design commission serial number, construction party, and construction date, is sent from the business office computer 31 of the business office 3 to the server computer 11 of the office 1, and is stored in the article category information database 12.

[0054] In addition, data such as the construction design drawing 6 produced by the construction design 2 is also sent to the server computer 11 and stored in the article category information database 12 of the server computer 11.

[0055] The stored data is transmitted in accordance with a request from the construction design computer 21 or a request from a process of preparing components and the like constituting the building as the next process.

[0056] However, it is not limited to this configuration, and it may be configured to transmit data periodically.

[0057] Next, the hardware configuration of the server computer 11 is shown in FIG. 2.

[0058] The server computer 11 includes a CPU 42 as a central processing unit that performs calculation and control of data, a RAM 43, a ROM 44, an HDD 45, and a storage medium device 46 as a storage device.

[0059] The CPU 42 executes various processes in accordance with the programs stored in the ROM 44 or the HDD 45, and is responsible for the central distribution tasks for executing predetermined processes such as operation management of each functional configuration group and input/output control of each signal.

[0060] The RAM 43 appropriately stores data and the like necessary for the CPU 42 to execute various processes.

[0061] The keyboard 48 and the mouse 49 as input devices are appropriately operated when a predetermined command is input to the CPU 42.

[0062] In addition, the display device 50 and the printer 51 output and display information and images displayed in a predetermined format.

[0063] The storage medium device 46 is composed of an externally mounted hard disk, magneto-optical disk, CD-R, DVD, storage unit, and the like.

[0064] The communication device 47 transmits data to the Internet line 13, and then appropriately stores the received data through the Internet line 13.

[0065] The article category information database 12 storing various data for each article is stored in the HDD 45.

[0066] An example of the file structure of the article category information database 12 is shown in FIG. 3.

[0067] Various data such as the serial number of the design request, the name of the construction party, the ID of the proposed design drawing, and the ID of the construction design construction design drawing are registered in the document of the article category information database 12 as a record of each design request serial number.

[0068] In addition, the data registered in the article category information database 12 is transmitted in response to a transmission request request from the construction design computer 21 or the next step not shown.

[0069] It is recommended that design drawings and construction design drawings be extracted from other documents not shown in the article category information database 12 and sent, and each ID is used as the key.

[0070] Next, the process of creating and managing construction design drawings using the design assistance system S of this embodiment will be described based on the flowcharts of FIGS. 4 and 5.

[0071] The processing of the flowchart in FIG. 4 is controlled by the CPU 42 of the server computer 11.

[0072] In addition, the process of the flowchart of FIG. 5 is controlled by the CPU which is not shown in the construction design computer 21.

[0073] First, the processing of the server computer 11 will be described with reference to FIG. 4.

[0074] In this process, the server computer 11 receives a data transmission request from the construction design computer 21, and transmits the requested data.

[0075] In addition, data such as customer information and suggested design drawings that can be sent from the business office computer 31 and data such as construction design drawings that can be sent from the construction design computer 21 are received, and registered in the article category information database 12.

[0076] First, the server computer 11 starts the process of the flowchart in FIG. 4 under the condition of logging in from the outside (logging in from the office computer 31, the construction design computer 21, and the computer installed in the next step not shown) as a condition. .

[0077] When the processing starts, it is determined in step S1 whether or not it is a login from the office computer 31.

[0078] The communication between the server computer 11 and the business office computer 31 related to the present embodiment is configured as a communication from the business office computer 31 to the server computer 11 in one direction.

[0079] Therefore, in the present embodiment, the login from the business office computer 31 is a data reception request to the server computer 11.

[0080] Therefore, when it is determined that it is the registration from the business office computer 31 (step S1: Yes), the data that can be sent to the article category information database 12 is stored in step S2, and the processing is terminated.

[0081] The so-called data sent from the office computer 31 are customer information such as design request serial numbers, customer names, suggested design drawings, and individual requests from customers.

[0082] When it is determined that it is not the login from the office computer 31 (step S1: No), the process proceeds to step S3, and it is determined whether it is a data transmission request.

[0083] When it is not the login from the business office computer 31, the login is a login from the construction design computer 21, or a login from a computer installed in the next process not shown.

[0084] In this embodiment, the server computer 11 and the construction design computer 21 are configured for two-way communication.

[0085] Therefore, in step S3, it is determined whether the registration is a data transmission request or a data reception request.

[0086] In the case where it is determined that it is not a data transmission request (step S3: No), since the registration can be determined as a data reception request from the construction design computer 21, in step S4, the storage can be sent to the item category information database 12 Data and end processing.

[0087] That is, the server computer 11 is only configured as a data transmission request to a computer installed in the next step not shown, and the requested data is transmitted, and it is not configured to receive data from a computer installed in the next step not shown. data. Therefore, in step S3, when it is determined that it is not a data transmission request (a data reception request), it can be determined that it is a data reception request from the construction design computer 21.

[0088] The data sent from the construction design computer 21 are data such as the design request serial number, construction design drawing ID, and construction design drawing.

[0089] When it is determined in step S3 that it is a data transmission request (step S3: Yes), it is determined in step S5 whether it is a data transmission request from the construction design computer 21.

[0090] When it is determined that the data transmission request is not a data transmission request from the construction design computer 21 (step S5: No), the data is transmitted to a computer installed in the next step (not shown) in step S6, and the processing is terminated.

[0091] In this embodiment, the data transmission request to the server computer 11 is the construction design computer 11 and the computer installed in the next process (not shown in the figure) (the business office computer 31 is one-way communication as described above, and only to the service computer 11 Make a data reception request).

[0092] Therefore, when the data transmission request is not a request from the construction design computer 21, it can be limited to a request from a computer installed in the next process (not shown), so proceed to the computer installed in the next process. The data is sent.

[0093] In step S5, when it is determined that it is a data transmission request from the construction design computer 21 (step S5: Yes), the process proceeds to step S7, and it is determined whether the data requested for transmission is stored in the article category information database 12.

[0094] When it is determined that the data requested for transmission is not stored in the article category information database 12 (step S7: No), the process proceeds to step S8, and an error signal is sent to the construction design computer 21.

[0095] As described below, when this error signal is received, an error display is performed on the construction design computer 21 side.

[0096] However, this error display processing is not necessarily required. For example, instead of the error display, the error may be notified by sound.

[0097] When an error signal is sent in step S8, the process proceeds to step S9 to perform error display.

[0098] In addition, the configuration for notifying abnormality may be an alarm, or may be configured to issue an audio message such as "abnormal data detected".

[0099] In step S7, when it is determined that the data requested to be transmitted is stored in the article category information database 12 (step S7: Yes), the process proceeds to step S10, the data is transmitted to the construction design computer 21, and the process ends.

[0100] Next, the processing of the construction design computer 21 will be explained with reference to FIG. 5.

[0101] In the processing of the construction design computer 21, a data transmission request and a data reception request are made to the server computer 11.

[0102] The construction design computer 21 starts the process of the flowchart of FIG. 5 on the condition that it starts to log in to the outside.

[0103] When the processing starts, in step S11, it is determined whether or not the registration is a registration for data transmission to the outside.

[0104] In step S11, when it is determined that it is a registration for data transmission to the outside (step S11: Yes), the process proceeds to step S12, the data is transmitted to the server computer 11, and the process ends.

[0105] At this time, the construction design computer 21 transmits data such as the created construction design drawings to the server computer 11.

[0106] In step S11, when it is determined that it is not a registration for data transmission to the outside (step S11: No), the process proceeds to step S13, and a data transmission request is made to the server computer 11.

[0107] The data transmission request is to request the server computer 11 to request the data transmission required by the data recorded in the article category information database 12 of the server computer 11.

[0108] The requested data is data such as customer data, suggested design drawings, and customer's individual request information. The design request serial number is used as a key word to search and send various information.

[0109] Next, the process proceeds to step S14 to determine whether an error signal is received.

[0110]The so-called error signal is a signal sent from the server computer 11 (the signal sent in step S8 of FIG. 4), which is sent to the construction company when the data corresponding to the requested design order number is not stored in the article category information database 12. Design the signal of the computer 21.

[0111] In step S14, when it is determined that an error signal is received (step S14: YES), the process proceeds to step S15 without performing an error display, and it ends with A.

[0112] Although the error display is performed in this embodiment, it is not limited to this, and error notification or the like may be performed by voice.

[0113] In step S14, if it is determined that an error signal has not been received (step S14: No), the process proceeds to step S16, and it is determined whether the data reception has ended.

[0114] If it is determined in step S16 that the data reception has not been completed (step S16: No), it is determined in step S17 whether or not a predetermined time has passed.

[0115] In step S17, when it is determined that the predetermined time has not elapsed (step S17: No), the process returns to step S14, and it is determined whether an error signal has been received.

[0116] If it is determined in step S17 that the predetermined time has elapsed (step S17: YES), an error display is performed in step S18 and the processing is terminated.

[0117] The predetermined time is sufficient time for receiving data, and the time from the data transmission request is monitored by a timer.

[0118] In addition, the so-called data reception that has not been completed after a predetermined period of time means that although sufficient time has elapsed to receive the data, the data reception has not been completed, and because there is a high possibility of communication abnormalities such as disconnection, an error is displayed. End the process.

[0119] In step S16, when it is determined that the data reception is completed (step S16: YES), the process proceeds to step S19, and the construction design drawing creation process is performed.

[0120] The construction design drawing preparation process will be described later.

[0121] Next, in step S20, it is determined whether the construction design drawing is stored in the storage device of the construction design computer 21.

[0122] When it is determined that the construction design drawing is stored in the storage device of the construction design computer 21 (step S20: Yes), the processing is ended by A.

[0123] In step S20, when it is determined that the construction design drawing is not stored in the storage device of the construction design computer 21 (step S20: No), in step S21, it is determined whether data transmission is instructed.

[0124] When it is determined that the data transmission is instructed (step S21: Yes), the process returns to step S12 from B, and the data is transmitted to the server computer 11.

[0125] When it is determined that the data transmission is not instructed (step S21: No), the process proceeds to step S22, and it is determined whether a predetermined time has passed.

[0126] When it is determined in step S22 that the predetermined time has not elapsed (step S22: No), the process returns to step S20, and it is determined whether the construction design drawing is stored in the storage device of the construction design computer 21.

[0127] If it is determined in step S22 that the predetermined time has elapsed (step S22: Yes), it is determined that the processing does not intend to continue, and the processing is terminated.

[0128] The prescribed time is set to a sufficient time for the completion of the construction design drawing production process. In the case that the construction design drawing preparation process has not been completed after the specified time, although sufficient time has passed for the completion of the construction design drawing preparation process, the processing is still not completed. Some problems may occur, so End processing.

[0129] Next, the construction design drawing preparation process will be described with reference to FIGS. 6 to 13.

[0130] The so-called construction design drawings are multiple drawings that record all the information necessary for the actual construction of the building. In the business office 3, the business person in charge creates each based on the recommended design drawings created for the purpose of presenting customers.

[0131] First, based on the proposed design drawing received from the server computer 11, the basic frame of the building shown in the construction design drawing is produced at each stage.

[0132] When a figure selection is instructed from an initial screen not shown, a selection screen 60 is displayed as shown in FIG. 6 and a necessary figure is opened from the selection screen 60.

[0133] This operation is performed by selecting among the check boxes given in front of the required figure (selecting by clicking the check box), and selecting the OK button 61 as a command to start the figure.

[0134] Also, the unselectable (non-existent) graphics are displayed shallowly, and no selection is available in the check box.

[0135] According to the basic framework of the construction design drawing, the person responsible for making the graphic shape of the construction design 2 prepares the construction design drawing.

[0136] Waterproof and thermal insulation materials are not detailed in the recommended design drawings, and such parts that do not affect the strength of the building are directly input into the basic frame of the construction design drawing.

[0137] In this way, the drawings required at each stage are produced, and all these produced drawings constitute construction design drawings.

[0138] In addition, the part that affects the strength of the building, such as the number of load-bearing walls, is a system that automatically creates and calculates.

[0139] The automatic production calculation system for the number of load-bearing walls, etc. will be explained below.

[0140] First, in the selection screen 60, select the target area described in one row of the load-bearing wall calculation chart.

[0141] This is selected by selecting from the check box given in front of the target area.

[0142] In FIG. 6, the second-order graph is selected, and the selection is made in the check box 62.

[0143] In this state, when the OK button 61 is selected, as shown in FIG. 7, a second-level load-bearing wall number calculation condition setting screen 70 is displayed.

[0144] In the load-bearing wall quantity calculation condition setting screen 70, each condition necessary for calculating the number of load-bearing walls is input.

[0145] Here, based on the input conditions, the construction design computer 21 creates building information for calculating the load-bearing capacity.

[0146] In the load-bearing wall number calculation condition setting screen 70, check boxes of items that must be selected are displayed in white, and check boxes of items that do not need to be selected are displayed in gray.

[0147] In addition, a drop-down button is set in the check box of each item. When the drop-down button is selected, the selection items that can be input in each item are displayed.

[0148] In this way, the predetermined parts used in the building, the conditions required in the building, and the like are selected from the selection items.

[0149] After all the items required for selection are selected, when the OK button 71 is selected, the load-bearing wall line automatic creation screen 90 shown in FIG. 9 is displayed.

[0150] In addition, in the case of special conditions such as the case of a construction building such as a heavy snow area, the condition is set on the building specification screen 80 shown in FIG. 8.

[0151] The building specification screen 80 can be selected from an initial screen not shown.

[0152] For example, as shown in FIG. 8, in the case of a normal area, the item of the check box 81 showing the area division selects "General area snow ≤ ○ cm", and in the case of building a building in a heavy snow area, select "Snowy area" is an item of the check box 81.

[0153] In this case (when "snow area" is selected), you can select the items related to the snow cover of the bearing wall number calculation condition setting screen 70, that is, the unit weight of snow 72, the short-term reduction rate of snow load 73, Snow load roof reduction gradient 74 checkbox.

[0154] FIG. 9 shows an automatic production screen 90 of the load-bearing wall line.

[0155] The load-bearing wall line automatic production screen 90 displays the name of each room, the load-bearing wall line 91 along the outer wall line, and the load-bearing wall number table 92 necessary for each load-bearing wall line.

[0156] Also, there are multiple load-bearing wall lines 91 along the outer wall line, and the necessary load-bearing wall tables are made for each outer wall line. Since the operation and processing are the same, only one load-bearing wall line 91 and Description of the number of necessary load-bearing walls in table 92.

[0157] The necessary load-bearing wall quantity table 92 consists of a wind pressure allowable elastic limit column 92a, an earthquake allowable elastic limit column 92b, a horizontal elastic limit column 92c, a bearing wall line name column 92d, a wind elasticity limit display column 92e, and an earthquake damage elasticity limit display column 92f, the earthquake collapse elasticity limit display column 92g constitutes.

[0158] The so-called wind pressure allowable spring force limit column 92a is a column that displays the value of resistance when wind pressure is applied to the building, and the so-called earthquake allowable spring force limit column 92b is a column that displays the value of seismic resistance when an earthquake occurs.

[0159] Similarly, the so-called level-maintaining elastic limit column 92c is a column that displays the elastic limit of the building level when an external force is applied to the building.

[0160] The load-bearing wall line name column 92d is a column that displays the coordinates of the place where the load-bearing wall line 91 is drawn.

[0161] Although omitted due to complicated graphics, a grid is displayed on the load-bearing wall line automatic creation screen 90, and the coordinates are specified based on the grid.

[0162] The wind elastic force limit display column 92e displays a value obtained by subtracting the wind pressure allowable elastic force limit from the number of walls necessary during a storm.

[0163] In addition, the earthquake damage elastic limit display column 92f displays the value obtained by subtracting the earthquake allowable elastic limit from the number of walls necessary during the earthquake (to prevent damage).

[0164] In addition, in the earthquake collapse elastic limit display column 92g, the value for maintaining the horizontal elastic limit is subtracted from the number of walls necessary during an earthquake (to prevent collapse).

[0165] The unit is ton.

[0166] The undertaker of the construction design 2 adds or deletes the load-bearing wall and the like in the load-bearing wall line automatic production screen 90, and completes the construction design drawing.

[0167] Also, the position of the load-bearing wall entered here is the position information used to calculate the load-bearing.

[0168] First, explain the input method of the load-bearing wall.

[0169] An item called a load-bearing wall, not shown, is selected from the "member (B) 93" of the pull-down menu set on the load-bearing wall line automatic production screen 90.

[0170]When an item called a load-bearing wall (not shown) is selected, a dialog box 100 shown in FIG. 10 is displayed.

[0171] Fig. 10(a) is a dialog box 100 showing the case of selecting a load-bearing wall, and Fig. 10(b) is a dialog box 100 showing the case of selecting a high-bearing wall.

[0172] As shown in FIG. 10, a drop-down button is set in the load-bearing wall type selection column 101, and the drop-down button is selected to specify the type of load-bearing wall to be input.

[0173] In addition, the type of load-bearing wall entered here is the specification information for calculating the load-bearing.

[0174] In addition, similarly, the number of load-bearing walls to be installed is designated in the number selection column 102.

[0175] In addition, a selection is made in the check box in the input level setting column 103, and the input level is specified.

[0176] In this way, the type of bearing wall and the number of bearing walls are performed in the dialog box 100, and after setting the steps, the bearing wall is input on the bearing wall line 91 of the bearing wall line automatic creation screen 90.

[0177] The input of the load-bearing wall can be input only by specifying two points.

[0178] As shown in Fig. 10(a), the reference bearing wall is designated in the dialog box 100, two points are designated in the automatic production screen 90 of the bearing wall line, and the reference bearing wall 103 is made between the two points.

[0179] Similarly, as shown in FIG. 10(b), the high load-bearing wall is designated in the dialog box 100, two points are designated in the load-bearing wall line automatic production screen 90, and the high load-bearing wall 104 is made between the two points.

[0180] By repeating this operation, a load-bearing wall can also be made on the load-bearing wall line 91.

[0181] In this process, since the load-bearing weight of the building changes every time the load-bearing wall is added, the value of each item in the necessary load-bearing wall quantity table 92 is recalculated and changed.

[0182] The operation of forming the load-bearing wall ends when the values in the wind elastic limit display column 92e, the earthquake damage elastic limit display column 92f, and the earthquake collapse elastic limit display column 92g are negative.

[0183] That is, the so-called negative values of these values mean that the necessary wall volume for each item exceeds the allowable elasticity limit, so when these values are negative, the necessary load-bearing capacity of the building is provided.

[0184] Next, the input of the structural column will be explained.

[0185] Since the input of the structural column is the same as the input of the load-bearing wall, only the difference will be explained briefly.

[0186] From the "member (B) 93" of the pull-down menu set on the load-bearing wall line automatic creation screen 90, an item called a structural column, not shown, is selected.

[0187] When an item called a structural column (not shown) is selected, the dialog box 110 shown in FIG. 11 is displayed.

[0188] As shown in FIG. 11, a pull-down button is set in the structure column type selection column 111, and the pull-down button is selected to specify the type of structure column to be input.

[0189] In addition, similarly, a drop-down button is also provided in the structural column partition selection column 112, and the drop-down button is selected to specify the structural column partition to be input.

[0190] In addition, a selection is made in the check box in the input method setting column 114 to specify the input method.

[0191] Similarly, select the check box in the input level setting column 115 to specify the input level.

[0192] In this way, in the dialog box 110, after setting the type of structural column, the partition of the structural column, the input method, and the input level, the structural column is input on the load-bearing wall line 91 of the load-bearing wall line automatic creation screen 90.

[0193] For the input of the structural column, when "one point" is selected in the input method setting column 114, the structural column can be formed by only specifying a point, and when "one point + direction" is selected in the input method setting column 114, it is possible The structural column is formed by clicking and specifying the reference point and the direction of the structural column to be set.

[0194] Also, when the detailed pattern 113 is selected, detailed descriptions such as the specifications of the structural pillars that can be selected are displayed.

[0195] By repeating this operation, a structural column can also be fabricated on the load-bearing line 91.

[0196] In this process, since the load-bearing capacity of the building with structural columns changes each time, the value of each item in the necessary load-bearing wall table 92 is calculated and changed again.

[0197] In addition, in the load-bearing wall line automatic production screen 90, the load-bearing wall line 91 can be added and deleted.

[0198] The item of the load-bearing wall line which is not shown in the figure is selected from the "member (B) 93" of the pull-down menu set on the load-bearing wall line automatic creation screen 90.

[0199] The mode at this time is "input".

[0200] When an item called a load-bearing wall line, which is not shown, is selected, a dialog box 120 shown in FIG. 12 is displayed.

[0201] In the dialog box 120, the input direction setting column 121 is set, a check box is selected in the input direction setting column 121, and the input direction is specified.

[0202] In this way, after the input direction is set, a point on the grid of the screen 90 is automatically created by designating the load-bearing wall line.

[0203] When a point is designated, when the "X line" is designated, the load-bearing wall line 91 is additionally formed in the X-axis direction from the designated point, and when the "Y line" is designated, the load-bearing wall line 91 is additionally formed in the Y-axis direction.

[0204] At this time, a table 92 of the number of necessary load-bearing walls corresponding to the added load-bearing wall line 91 is created at the same time.

[0205] It is also possible to eliminate the load-bearing wall line 91.

[0206] As with the case where the load-bearing wall line 91 is added, an item called the load-bearing wall line, not shown, is selected from the "member (B) 93" of the pull-down menu set in the load-bearing wall line automatic creation screen 90.

[0207] The mode at this time is "eliminate".

[0208] The subsequent operation is the same as the addition. A dialog box not shown is displayed. After selecting the erasing method (point indication, straight line indication, range indication, etc.) in the dialog box, specify and erase the load-bearing wall line on the automatic creation screen 90 The load-bearing wall line 91 to be eliminated.

[0209] At this time, the necessary load-bearing wall quantity table 92 corresponding to the eliminated load-bearing wall line 91 is eliminated at the same time.

[0210] Also, when an item called a load-bearing wall line not shown is selected from the "Component (B) 93" of the pull-down menu set on the load-bearing wall line automatic creation screen 90, and the mode is changed to "Change", A dialog box (not shown) for moving the position of the necessary load-bearing wall quantity table 92 is displayed.

[0211] In addition, when you select the item called the side distribution of the load-bearing wall, which is not shown in the figure, from the "Component (B) 93" of the pull-down menu set in the automatic creation of load-bearing wall line screen 90, it will be displayed for the other load-bearing wall line 91 (one side) equally divided load-bearing dialog box not shown.

[0212] In addition, when an item referred to as the distribution of both sides of the load-bearing wall, which is not shown, is selected, a dialog box not shown for the load-bearing to be equally divided on the other load-bearing wall lines 91 (both sides) is displayed.

[0213] In this way, the load can also be distributed automatically.

[0214] In addition, when you select the item called “Removal of all load-bearing wall assignments” from the drop-down menu set in the load-bearing wall line automatic creation screen 90, a message asking whether to abandon the assignment results will be displayed when the item called “Removal of all load-bearing wall assignments” is selected. .

[0215] When the message selects OK, all distribution results are discarded, and the number of load-bearing walls before distribution is automatically restored.

[0216] Also, in the case of re-input of load-bearing walls, load-bearing wall lines, and load-bearing wall distribution, seismic force and wind pressure are recalculated.

[0217] The reason for this function is that when the load-bearing wall, the load-bearing wall line, and the load-bearing wall distribution are changed, the load-bearing balance of the entire building may change, so it needs to be calculated again.

[0218] This operation is performed by selecting an item called seismic force and wind pressure calculation, which is not shown, from the "member (B) 93" of the pull-down menu set on the load-bearing wall line automatic creation screen 90.

[0219] Finally, confirm the end of the load-bearing wall.

[0220] This is the final confirmation that there is no problem with the weight of the building, and the center of gravity and rigidity are produced and displayed at the end.

[0221] When an item called the end confirmation of the load-bearing wall is selected from the "member (B) 93" of the pull-down menu set in the automatic creation of the load-bearing wall line screen 90, the end confirmation of the load-bearing wall is executed.

[0222] At this time, when problems such as insufficient number of walls and offset of load-bearing walls are detected, an error message is displayed.

[0223] In the case where no problem is detected, as shown in FIG. 13, a screen 130 for calculating the number of load-bearing walls is displayed.

[0224] The load-bearing wall number calculation drawing 131 displayed on the load-bearing wall number calculation screen 130 is a figure constituting a construction design drawing.

[0225] At this time, the gravity center position 132, the rigid center position 133, and the origin position 134 are displayed in the load-bearing wall number calculation map 131.

[0226] In this way, each created figure is stored in the storage device of the construction design computer 21 as a construction design drawing, or is transmitted to the server computer 11.

[0227] As described above, based on the suggested design drawings prepared for presenting customers in the business office 3, a plurality of construction design drawings necessary for the actual construction of the building are created, and finally stored in the article category information database of the server computer 11. 12 and manage it.

[0228] According to the present invention, the construction design drawing making and sending device is configured to receive the suggested design drawing prompted to the customer, and to make the construction design drawing based on the suggested design drawing.

[0229] As a result, the construction design drawings necessary for the actual construction of the building can be quickly produced from the recommended design drawings presented to the customer.

[0230] Therefore, according to the construction design drawing, the parts and members necessary for the construction of the building can be quickly and efficiently prepared in the next process.

[0231] For this reason, the construction of the building can be made efficient, the construction period can be shortened, and the cost can be reduced at the same time.

[0232] In addition, since the graphic information is uniformly managed by the design drawing management device, management is easy, and problems such as graphic loss can be eliminated. In addition, it is also advantageous when processing information and the like.

[0233]In addition, the construction design drawing preparation and transmission device calculates the load-bearing capacity of the building based on the set building information and the specification information and position information of the load-bearing wall described in the drawing.

[0234] In addition, the construction design drawing creation and delivery device confirms that the calculated load is a predetermined value, and only when it is a predetermined value, creates a construction design drawing that can be sent.

[0235] Therefore, if there is no prescribed load-bearing capacity, the construction design drawing will not be submitted to the next process.

[0236] For this reason, construction design drawings can be easily produced, and at the same time a building with a predetermined strength can be constructed reliably.

[0237] In addition, according to the present invention, the recommended design drawing transmitting device for transmitting the recommended design in the design drawing management device is installed in the business office.

[0238] As a result, the recommended design drawing reflecting the customer's intention can be sent online to the design drawing management device in the business office, so the recommended design drawing can be quickly submitted to the next process.

[0239] For this reason, while the construction period can be shortened, there is no suggestion that the design drawings are lost.
