FIG. 2 shows an example of a flowchart of the process chart creation support method according to the present invention, which is performed using the computer 1 shown in FIG. The processing contents will be described below with reference to the flowchart of FIG.
[0034]
When the above-described computer 1 is started (started), in step A, the process planner is first displayed in the dialog box 300 of FIG. 3 on the central processing unit 2 of the computer via the input device 3. When the building data composed of the corresponding three-dimensional CAD (Computer Aided design) data is selected and the read button 301 is clicked with the mouse 3b, the building data is automatically read.
[0035]
The building data is the design data of the building related to the construction work created by applying the CAD graphic processing function to drafting applications. The position and dimensions (vertical, horizontal, length, steel cross section) for each member And main data (columns, outer walls, door walls, large beams, small beams, balconies).
[0036]
Further, when the building data 511 is read, common item data accompanying the building data is automatically read and the dialog box 400 of FIG. 4 is displayed.
[0037]
In step B, building attributes such as floor structure, structure / construction method, member, work area, etc. that can be inferred from the setting items of the read common item data are automatically extracted from the model creation basic data group 531 of the basic data storage device 53. This is a step of creating a model of the building model 512 by associating with the building data.
[0038]
In the dialog box 400, common item data such as a construction code, a construction name, a client name, a building site, an application, a structure type, the number of basement floors, the number of ground floors, the number of tower floors, etc. are input in advance to each setting item 401. It is displayed. Therefore, when the process planner operates the mouse 3b of the input device 3 and clicks the determination button 403, the common item data is determined, and the floor structure, structure / construction method, member, work zone, etc. that can be determined from the common item data are determined. Each attribute is automatically extracted from the model creation basic data group 531 of the basic data group 53 by the central processing unit 2, and a model of the building model 512 for creating the process chart is automatically created. The building model 512 is the three-dimensional data. It is stored in the storage device 51.
[0039]
At this time, each building attribute automatically extracted from the model creation basic data group 531 is created as a structure attribute DB 513, a construction / construction method attribute DB 514, a member division / integration attribute DB 515, and a construction area attribute DB 516, and is sent to the three-dimensional data storage device 51. It is recorded and stored in a freely changeable manner. Then, the process proceeds to the next step C.
[0040]
When changing the common item data, the process planner inputs the changed item into each input column 401 by using the keyboard 3a of the input device 3. The structure format is referred to “structure format data” stored in the structure attribute data 531 a of the model creation basic data group 531 in the pull-down menu 402, and is selected by the process planner with the mouse 3 b of the input device 3. The overall structure format is set by. Also, with the model of the building model 512 in step B, the initial values of all the structural forms of the building model 512 are set with default values.
[0041]
Step C refers to the basic data device 53 in the model of the automatically created building model 512, and sets the details of the building attributes such as the floor structure, structure / construction method, member, work area, etc. This is a step of determining the building model 512.
[0042]
In step C-1, the structural attributes of the columns, large beams, and small beams are set in detail. First, the process planner operates the input device 3 to display the dialog box 500 of FIG. Basically, the structure format set in step B is displayed in the structure input field 501 as an initial value. If the structure differs depending on the floor, refer to the “structure format data” stored in the structure attribute data 531a of the model creation basic data group 531 to structure each structure format such as columns, large beams, and small beams on different floors. The input field 501 is entered and corrected using the keyboard 3a of the input device 3. Parts other than columns, large beams, and small beams are set as RC (steel reinforced) structures. When the determination button 502 is clicked with the mouse 3b, the central processing unit 2 determines the structural attribute of the building model 512 and updates the content in the structural attribute DB 513 of the three-dimensional data storage device 51. Also, attributes such as the construction / construction method and the member are estimated from the additional change, and the construction / construction method attribute DB 514, the member division / integration attribute DB 515, and the construction section attribute DB 516 are automatically changed.
[0043]
In step C-2, the details of the structure / construction method attributes of the main parts such as columns, outer walls, door walls, large beams, floors, balconies and the like are set freely.
First, the process planner operates the input device 3 to display the dialog box 600 of FIG. Basically, the values set or automatically changed in steps A and B are displayed as initial values. If there is no change in the displayed structure / construction method, the process proceeds to the next step. If there is a change in the setting items, the main parts of pillars, outer walls, door walls, large beams, floors, balconies, and small beams in the structure / construction method box 601 surrounded by solid lines on the dialog box 600 Separately, the construction method 602, the reinforcing bar 603, and the formwork 604 are changed by referring to the construction / construction method attribute data 531b stored in the model creation basic data group 531 of the basic data storage device 53. Do.
[0044]
Specifically, the construction method 602 is determined by selecting a corresponding schematic construction method from the respective construction pull-down menus 602a... Provided in a column for each main part by the mouse 3b of the input device 3. In the construction method pull-down menu 602a, “schematic construction method data” of construction / construction method attribute data 531b is referred. The reinforcing bar 603 is determined by selecting a corresponding reinforcing bar construction method by using the mouse 3b of the input device 3 from each reinforcing bar pull-down menu 603a. In the reinforcing bar pull-down menu 603a, “reinforcing method data” of the construction / construction method attribute data 531b is referred. The formwork 604 is determined by selecting a corresponding formwork method from the respective formwork pull-down menus 604a... Provided in a column for each main part by the mouse 3b of the input device 3. In the form pull-down menu 604a, “form work method data” of the construction / construction method attribute data 531b is referred.
[0045]
Further, the steel frame construction 605, the steel node split 606, the steel joint 607, the concrete placement 608, and the main reinforcement joint 609, which are considered common to a plurality of parts, are set in the same procedure as described above. That is, the reinforcing bar construction 605 changes the setting according to the actual situation from the steel construction pull-down menu 605a in which the “steel construction data” of the construction / construction method attribute 531b is referenced.
[0046]
The steel node division 606 is changed in accordance with the actual condition by the mouse 3b of the input device 3 from the node pull-down menu 606a in which “steel node division data” of the structure / construction method attribute 531b is referred. The steel joint 607 is changed in accordance with the actual condition by the mouse 3b of the input device 3 from the joint pull-down menu 607a in which “steel joint construction method data” of the structure / construction method attribute 531b is referred. The concrete placement 608 is changed in accordance with the actual condition by the mouse 3b of the input device 3 from the placement pull-down menu 608a in which the “concrete placement method data” of the construction / construction method attribute data 531b is referred. The reinforcing bar main joint 609 performs setting change according to the actual condition from the reinforcing bar main bar pull-down menu 609a to which the “reinforcing bar main reinforcing bar joint data” of the construction / construction method attribute data 531b is referred to by the mouse 3b of the input device 3.
[0047]
In addition, when S or SRC structure is not selected in the structure setting of step B, the setting of 605 to 607 considered to be common to a plurality of parts is unnecessary, and is not displayed in the setting items.
[0048]
When the construction / construction method determination button 610 is clicked with the mouse b of the input device 3, the composition / construction method for each floor and site shown in the dialog box 700 of FIG. 7 is automatically set by the central processing unit 2, The entire structure / construction method and floor-part structure / construction method attribute are associated with (added to) the building data. In the illustrated example, the floor-by-floor construction method for the pillar is displayed. Of course, since each structure / construction method may differ depending on the floor, an appropriate structure / construction method is input to each entry field 701 of this dialog box 700 with reference to the data of each structure / construction method data in the structure / construction method attribute data 531b. Additional changes can be made by the device 3.
[0049]
Then, the central processing unit 2 associates the construction / construction method attributes of the building model 512 and reflects (updates) the contents in the construction / construction method attribute DB 514 of the three-dimensional data storage device 51. Further, the core, floor level basic member division, and the attribute of the work area estimated from the additional change are calculated, and the member division / integration attribute DB 515 and the work area attribute DB 516 are automatically changed.
[0050]
In Step C-3, the process planner is a step of dividing and integrating the members to determine the attributes of the members. As described above, some basic member division is automatically performed in Step C-2. Has been. When further dividing or modifying the member, as shown in the dialog box 800 of FIG. 8, the portion to be divided into each member such as a column, a large beam, a small beam, etc., based on the core X1 to Xn and Y1 to Yn of the member. That is, dividing lines Lx... Provided in the X-axis direction, Ly... Provided in the Y-axis direction are provided (pulled) by operating the mouse 3b of the input device 3, and the type of member to be divided is designated in the box 801. The above procedure is repeated for each floor to perform member division. At that time, if the position of the dividing line is the same as the other floors, the position of the dividing line can be copied. Then, by clicking the division determination button 802 in the box 801 with the mouse 3b of the input device 3, the attribute of the member division is associated with the building data, and the content is reflected (updated) in the member division / integrated attribute DB 515.
[0051]
In the integration (unitization) of members, first, the process planner operates the input device 3 to display the dialog box 900 of FIG. Although the member division automatically set according to the setting of the member division is displayed, the designated members can be integrated individually according to the construction / construction method and construction period.
[0052]
The integration (unitization) of the members means that a plurality of members constituting the building are combined in advance at a factory or the like, and set as a single member, for example, transported to a predetermined location with a tower crane or the like. It is.
[0053]
As a member dividing procedure, first, the members are combined by combining a plurality of the members with respect to the members divided into the respective members such as columns, large beams, and small beams in the above-described member dividing process. For example, when setting the integrated member 9 composed of the respective members of the columns A, B and the large beam C, the columns A, B and the large beam C are designated in series with the mouse 3b, and the unitization designation button 901 is set to the mouse 3b. Click to select a member unit and a mark member unit (not shown) in order, and a member type box 902 in which member data of the member attribute data 531c is referenced is displayed. The selected member type names are selected with the mouse 3b and clicked on the enter button 903 to be integrated.
[0054]
The part type name displayed in the box 902 is not only “automatically set part attribute data” of the member attribute data 531c (main parts such as columns, large beams, small beams, floors, balconies, door walls and outer walls). In the member attribute data 531c, for example, “exterior unit” composed of members of columns, large beams, and outer walls, and “bay” composed of columns, large beams, outer walls, small beams, and floors. About 27 types can be selected, such as “unit” and “floor panel with large beams” composed of large beams, small beams and a floor.
[0055]
Regarding the integration of the columns, the central processing unit 2 automatically integrates the members based on the setting value of the steel frame division 606 of the structure / construction method attribute of FIG.
[0056]
When the determination button 903 in the member type box 902 is clicked with the mouse 3b of the input device 3, the members are integrated, the attributes of the members are associated with the building data, and the contents are reflected in the member division / integration attribute DB 515 ( Updated).
[0057]
In Step C-4, the scope of the work area and the name of the work area are designated to confirm the work area attributes. First, the process planner operates the input device 3 to display the dialog box 1000 of FIG. Subsequently, by operating (dragging) the mouse 3b of the input device 3, the range of the work area is set in a polygon with a single drawing of the plan view of the dialog box 1000, and the name of the designated work area in the work area name box 1001 Is selected. Repeat the above procedure for each floor to set up the work section division. In the box 1001, “section name list data” of the section attribute data 531d is referred. At that time, if the position of the work section dividing line is the same as the other floors, it can be copied.
[0058]
Then, by clicking the work area determination button 1002 in the work area name box 1001 with the mouse 3b of the input device 3, the work area attributes are associated with the building data 511, and the contents are updated to the work area attribute DB 516.
[0059]
As described above, the building model for creating the process chart is determined in step C, and is recorded and stored in the building model 512 of the three-dimensional data storage device 51.
[0060]
In subsequent step D, the central processing unit 2 automatically calculates the floor distinguishing construction quantity based on the confirmed building model 512 for each floor section and item.
[0061]
Specifically, the “construction quantity” of the construction quantity calculation data 532f of the structural attribute DB 513, the construction / construction method attribute DB 514, the member division / integration attribute DB 515, the construction section attribute DB 516, and the process creation basic data group 532 added to the building model 512 is added. With reference to “classification data”, the amount of concrete, formwork area, number of member pieces, steel weight, steel weld length, rebar weight, number of steel joints, etc., which are basic building materials, are calculated.
[0062]
Among the basic materials, the amount of reinforcing bars and the number of rebar joints are not registered in the building data, so “reinforcing bar step data” (concrete 1 m) of the construction quantity calculation data 532f. ³ The number of hitting reinforcing bars) and “joint step data” (number of upper and lower ends per divided surface of the member) are calculated. In addition, considering that the construction quantity varies depending on the construction / construction method to be adopted, see “Construction quantity computation data” in construction quantity computation data 532f that indicates the relationship between the basic materials and the construction quantity corresponding to the construction / construction method. It is assumed that the calculation is more realistic.
[0063]
The floor distinction construction quantity calculated as described above is output and displayed on the monitor 4a of the output device 4 as in a dialog box 1010 shown in FIG. Is recorded and stored.

Next, in step E, a basic tact process based on the process creation basic model is created. First, the expression method of the basic tact process created in step E will be described.
[0065]
In the tact process of building work, even if the construction quantity of the floor work zone is different, the structure / construction method to be adopted and the attributes of the members included in the work area are often exactly the same, in which case the tact process (the required work and its work) The work name and procedure are also the same. Therefore, the structure / construction method to be used and the attributes of the members included in the work section are exactly the same, and a tact process that can be used in common in the floor work section is created as a “basic tact process”, taking into account the convenience at the time of modification. . As an overview of the basic tact process creation method, process procedures that can be applied to all construction / construction methods and member attributes for each part as shown in FIG. 12 are set, and each work is based on the construction / construction method and member attribute data. If it is necessary to change the work, it is replaced with the work name corresponding to the construction / construction method and member attribute. If it is not necessary, the work is deleted and the subsequent work is sequentially performed. Stuff before. In addition, the same work name is placed before and after the order relations that may be reversed depending on the construction and construction method, and an expression method in which one of them is selected is adopted.
[0066]
However, since there are few process charts expressed for each part as a practical process expression method, it is generally expressed by work type (for example, steel frame, reinforcing bar, formwork, concrete, etc.). It is necessary to change from the site-specific process chart shown in Fig. 13 to the process-specific process chart shown in Fig. 13. That is, the basic tact process is a display system grouped into two types of steel tact M and frame tact N as shown in FIG. The steel frame tact M and the body tact N are different from each other.
[0067]
First, a procedure for creating the steel tact M will be described. In order to become the description expression for each section set in the step C, for example, the steel frame construction work is performed from the bottom line to the top line of the number of lines in consideration of the number of floors corresponding to each section. Write a line and display the other steel joint operations on the top line. In FIG. 13, since the steel frame construction method with two layers and one node is adopted, the number of rows of the floor corresponding to the node is six rows in total. Therefore, the steel frame construction work is expressed from the first row on the Nth floor to the third row on the (N + 1) th floor.
[0068]
Next, in the case tact N, an expression method is adopted in which the first line is fixed as a common work and concrete work in each part, the second line is a reinforcing bar work, and the third line is fixed as a formwork. The basic tact process template created by the realistic process expression method shown in FIG. 13 is stored as “process group order relation data 532 a” of the process creation basic data group 532.
[0069]
In addition, the process expression method of the “process group order relation data 532a” of the basic tact process is the main member set in step C-2 (column, large beam, floor, balcony, door wall, exterior wall, common 7 types) The process display is based on the combination of each process. However, in actuality, it is necessary to deal with all 34 types (27 types of additional sites + 7 types of main sites) added in the member integration setting performed in step C-3 and each process.
[0070]
Columns include pillars + pillars (with and without brackets), pillars + large beams (vertical / horizontal layers), pillars + large beams + outer walls (exterior units), pillars + large beams + exterior + small beams + floors (bay units), Pillar + Pillar (leading), Pillar + Pillar (following), Exterior unit (leading), Exterior unit (following), Bay unit (leading), Bay unit (following), Pillar (leading), Pillar (following) ) In addition, for large beams, large beams + small beams + floor (floor panels with large beams), large beams (leading), large beams (following), floor panels with large beams (preceding), floor panels with large beams (following), It is necessary to add a small beam + floor (floorless floor panel), large beamless floor panel (leading), large beamless floor panel (following), small beam (leading), and small beam (following) to the floor. . Therefore, the combination of processes considering the structure, construction method, and member type for each part is 1619 “column construction / construction method”, 13 “exterior wall construction / construction method”, 9 “door boundary construction / construction method”, There are 548 streets and construction methods, 13 floors and construction methods, 11 balcony constructions and construction methods, and 3 common constructions and construction methods. When all parts are combined, there are more than 12.7 billion basics. A tact process can be created. Therefore, the process combination data (street) of each structure / construction method is stored in the structure / construction method / member attribute-process data 532b of the process creation basic data group 532 so that it can be referred to for each construction method. Therefore, it contributes to the creation of a process chart corresponding to the difference in all constructions, construction methods and members during construction.
[0071]
Next, a procedure for creating a basic tact process that reliably corresponds to the member integration setting performed in step C-3 will be described.
[0072]
The basic tact process table is created separately from the process part of the basic tact process and the construction work part including the work, work sequence and construction work corresponding to the process part, as shown in FIG. Is done. First, the creation of the process part of the basic tact process will be specifically described based on the flowchart shown in FIG.
[0073]
In step E-10, the central processing unit 2 checks whether there is a floor work section in which all parts have the same construction / construction method and member type. That is, based on the building model 512, the number of floor sections with different floor distinction member attributes is calculated to determine the number of basic tact steps.
[0074]
If it is determined in step E-11 that all the construction / construction methods and members do not have the same floor work section (NO), the process proceeds to the next step E-12 to add a basic tact process. If there is (YES), the process proceeds to step E-30, and the same check is performed for all the floor sections.
[0075]
In step E-13, the central processing unit 2 firstly records and stores the column structure / construction method and member attributes recorded in the structure / construction method / member attribute-process data 532b of the process creation basic data group 532. The process combination data (1619) of the “structure / construction method” and the structure / construction method attribute DB 514 of the building model 512 for process creation are collated to check the number of floor sections with different structure / construction method and member attribute data. Determine the number of tact steps.
[0076]
Then, in step E-14, in each basic tact process, the process related to the column based on the process group order relation data 532a of the process creation basic data group 532 and the process combination data of the “column structure / construction method”. The unnecessary process group is automatically deleted, and the necessary process group is automatically given an appropriate work item name. As a result of the corrected basic tact process, as shown in FIG. 15, processes related to the pillars of the basic tact are determined by the expression method grouped into the steel tact M and the frame tact N. Since the determination result of the process related to each main part, which will be described later, is also the same expression method as that of FIG.
[0077]
In step E-15, the central processing unit 2 processes the “outer wall construction / construction method” stored in the construction / construction method / member attribute-process data 532b of the process creation basic data group 532 in the type of exterior wall construction / construction method. The combination data (13 types) is collated with the structure / construction method attribute DB 514 of the building model 512 for process creation. In step E-16, the necessity of the process is determined, unnecessary process groups are automatically deleted, and necessary process groups are automatically given appropriate work item names.
[0078]
In step E-17, the central processing unit 2 stores the “door boundary wall structure / structure” in the process creation basic data group 532 in the structure / construction method / member attribute-process data 532b in the type of the boundary wall structure / construction method. The “combination method” process combination data (9 types) and the construction / construction method attribute DB 514 of the building model 512 for process creation are collated. In step E-18, the necessity of the process is determined, unnecessary process groups are automatically deleted, and necessary process groups are automatically assigned appropriate work item names.
[0079]
In step E-19, the central processing unit 2 stores the data of the “large beam construction / construction method” stored in the construction / construction method / member attribute-process data 532b of the process creation basic data group 532 in the large beam construction method and the type of member. The process combination data (548) and the construction / construction method attribute DB 514 of the building model 512 for process creation are collated. In step E-20, it is determined whether or not the process is necessary, and unnecessary process groups are automatically deleted, and necessary process groups are automatically given appropriate work item names.
[0080]
In step E-21, the central processing unit 2 stores and stores the “beam beam structure / structure method / member type” in the structure / structure / member attribute / process data 532b of the process creation basic data group 532 in the beam structure / structure method and member type. The “combination method” process combination data (13 types) and the construction / construction method attribute DB 514 of the building model 512 for process creation are collated. In step E-22, it is determined whether or not the process is necessary, and unnecessary process groups are automatically deleted, and necessary process groups are automatically given appropriate work item names.
[0081]
In step E-23, the central processing unit 2 processes the “floor construction / construction method” stored in the construction / construction method / member attribute-process data 532b of the process creation basic data group 532 in the type of floor construction / construction method. The combination data (46 ways) is collated with the structure / construction method attribute DB 514 of the building model 512 for process creation. In step E-24, it is determined whether or not a process is necessary, and unnecessary process groups are automatically deleted, and necessary process groups are automatically assigned appropriate work item names.
[0082]
In step E-25, the central processing unit 2 determines the process of “balcony structure / construction method” stored in the structure / construction method / member attribute-process data 532b of the process creation basic data group 532 in the type of balcony structure / construction method. The combination data (11 types) and the construction / construction method attribute DB 514 of the building model 512 for process creation are collated. In step E-26, the necessity of the process is determined, and unnecessary process groups are automatically deleted, and the necessary process groups are automatically given appropriate work item names.
[0083]
In step E-27, the central processing unit 2 processes the “common construction / construction method” stored in the construction / construction method / member attribute-process data 532b of the process creation basic data group 532 in the common construction / construction method type. The combination data (three types) is collated with the structure / construction method attribute DB 514 of the building model 512 for process creation. In step E-28, the necessity of the process is determined, unnecessary process groups are automatically deleted, and necessary process groups are automatically given appropriate work item names.
[0084]
In this way, in steps E-13 to E-28, check the pillars, outer walls, door walls, large beams, small beams, floors, balconies, common structures, construction methods, and types of members, and perform only necessary work. The process part of the basic tact process is created by extracting and automatically assigning an appropriate work item name in the work order according to the actual situation.
[0085]
When a series of check steps is completed, the new basic tact process is stored in the process data storage device 52 in step E-29.
[0086]
In step E-30, if all floor work zones have been checked (YES), creation of the process part of the basic tact process is completed. Then, it is displayed for each basic tact process created in the process column 161 of the dialog box 160 shown in FIG.
[0087]
The basic tact process shown in FIG. 15 is created by the number of different structures / construction methods employed for construction distinction and the attributes of members included in the construction section. In other words, if the same construction / construction method and the same part attributes are selected in all floor construction zones, one basic tact process, and if a different construction / construction method is selected in all floor construction zones, The basic tact process for the number of work areas is displayed.
[0088]
Next, a construction step portion (pick-up display column 162) corresponding to the created step portion of the basic tact step is created. In other words, the central processing unit 2 refers to the work-specific construction progress data 532c and the work-specific input resource quantity data 532d of the process creation basic data group 532, extracts the corresponding values, and determines the construction yield and the input resource quantity. This is done by displaying it in the progress display column 162 on the dialog box 160.
[0089]
By the above procedure, a process part and a construction step part are created, and a basic tact process is created according to the actual situation. Then, it is recorded and stored as basic tact process data 522 in the process data storage device 52.
[0090]
Of course, if editing is required, it can be done on this dialog box 160. Items that can be edited are process addition 163, relation line addition 164 for displaying the work name, work name change 165, work name movement 166, start point line movement 167, end line movement 168, process line movement 169, construction of step display column 162 There are 10 items of step and daily input. Click each button to edit. When editing the construction progress portion, the change value in the progress display column 162 surrounded by a thick line is edited by operating the keyboard 3a of the input device 3. Each editing result is stored in the process data storage device 52, and is reflected in the method for expressing the floor distinguishing tact in the next item and the calculation of the number of days for each work day.
[0091]
Next, referring back to the flowchart of FIG. 2, the overall process creation step F will be described with reference to the drawings.
[0092]
First, in step F-1, a floor distinguishing tact process is created. The floor distinction tact process is the same form as the expression method of the basic tact process in terms of the number of days of each work calculated based on the above-mentioned floor distinction construction quantity, the construction tact of the basic tact process, and the daily input amount The tact process of each floor-work zone expressed in.
[0093]
In the basic tact process created in Step E, a process in which the number of work days is fixed without affecting the process expression method and the construction quantity is defined. Accordingly, it is necessary to confirm and change the contents of the tact process of each floor work section in which the work days change depending on the work quantity, work progress, and daily resource input amount. Therefore, the central processing unit 2 automatically creates a floor distinguishing tact process by assigning the floor distinguishing construction quantity 521 calculated in step D to the basic tact process and calculating the number of work days. Then, the result is displayed in the dialog box 170 shown in FIG. 17 and stored as “floor distinction tact process data 523” in the process data storage device 52.
[0094]
In the dialog box 170, the attributes such as the floor name, the work zone name, and the basic tact process name set in step C are displayed in the setting display column 171. The automatically created floor distinguishing tact process is displayed in the floor distinguishing process box. 172.
[0095]
In addition, the work content list box is based on the default (initial value) stored in the work-specific construction progress 532c and the work-specific input resource amount 532d. 173. In the box 173, the set value displayed and changed in the construction progress display column 162 in step E is also displayed in conjunction with it. The process planner checks each set value, and changes the set value using the keyboard 3a of the input device 3 when the change is necessary. In addition, when changing the work days, the construction quantity, the construction step, and the daily input amount are changed by the keyboard 3a.
[0096]
In step F-2, the work distinction order relationship is confirmed. This is because the creation of the entire process, which will be described later, is created on the basis of the order relationship between the tact process for distinguishing each floor work and the work section, and therefore, the order relation of the work section needs to be set in this step.
[0097]
The central processing unit 2 automatically creates a process order relation table based on the created floor distinction tact process data 523, the construction / construction method attribute DB 514, and the floor distinction process order relation data 532e of the process creation basic data group 532. . Then, the result is displayed in the dialog box 180 of FIG. 18 and stored in the process data storage device 52 as “floor zone order relation data 524”.
[0098]
Here, the floor name and the name of the work area, the connection relationship, and the number of connection days preceding the work distinction are displayed. The connection period of the work section is displayed as a default value obtained by dividing the process days of the first work section by the number of work sections. As shown in the connection relation column 181, four types of connection relations, SS (start-start), SF (start-finish), FS (finish-start), and FF (finish-finish) are prepared and displayed. Yes. When the connection relationship is changed, an appropriate setting is input to the preceding floor work area and the connection relationship column 181 using the keyboard 3a of the input device 3 or the like. Of course, the changed contents are updated to the “floor work section order relation data 524”.
[0099]
Then, the whole process is displayed in step F-3. The process created at the present time is in the working days format which is not date data. Therefore, as shown in FIG. 19, the process planner operates the input device 3 to designate the start date of the process in the start date entry field 191 of the dialog box 190 and clicks the decision button 192 with the mouse 3b. The central processing unit 2 performs an overall process corresponding to the actual number of days while correlating with each other on the basis of the created flooring distinction tact process data 523 and flooring distinction order relation data 524 stored in the process data storage device 52. A table is automatically created, and the result is displayed in the dialog box 200 shown in FIG. Then, the created entire process table is stored in the process data storage device 52 as “total process data 525”.
[0100]
The entire process chart is created through the above steps. Finally, in step G, a final confirmation is made whether there are any changes. If there is no change, all steps are terminated. When changing each building attribute or member type, the process returns to step C, and when changing the process order, construction step, etc. regarding the process chart, the process returns to step E and changes are made on each dialog box. Since the operations of all the steps described above are performed while being associated with each other, all the operations for the subsequent changes accompanying the change items are automatically performed and immediately reflected in the entire process chart.
[0101]
Thus, the whole process chart according to the actual condition can be created by steps A to G. Even if the process, member, etc. are changed, the entire process based on the change is linked to each building attribute additionally set in the building data by a simple method of editing on each illustrated dialog box. Since it can be created immediately, a more accurate process chart can be created easily and quickly.
[0102]
[Effects of the present invention]
According to the process chart creation support method according to the first to fourth aspects of the present invention, a detailed overall process chart in accordance with the actual situation is obtained from the building model 512 for process creation created by associating attributes with three-dimensional building data. It can be created easily.
[0103]
In addition, even if an addition / correction occurs due to a change in the construction plan, all the changes after the addition / correction are automatically performed and can be immediately reflected in the entire process chart.
