Mode for Carrying Out the Invention

[0010] Hereinafter, with reference to the drawings, preferred embodiments of the present invention will be described in detail. In this embodiment and the drawings related to this embodiment, components having the same reference numerals shall have the same structure or function.

[0011] <Necessity of the Construction Support System 10 and the Steel Bar Supply Support System 60> In recent years, for example, when constructing buildings such as buildings and complex facilities, it has been proposed to use BIM (Building Information Modeling). In BIM, parts are combined in a virtual space, and various information such as the weight of steel bars and the completion time is incorporated into the modeled building.

[0012] In reinforced concrete buildings, a large number of steel bars with various shapes and dimensions are used. In addition, in the process from the design to the processing of steel bars, many businesses such as design companies (including architectural design offices), construction sites, and steel bar processing contractors are involved.

[0013] Generally, for example, the reinforcement layout drawing and tabulation sheet created by a design company are sent to the construction site, and at the construction site, the work of creating a processing ledger from the reinforcement layout drawing and tabulation sheet is carried out. Further, the processing ledger is sent from the construction site to the steel bar processing contractor, and the steel bar processing contractor converts it into a two-dimensional code (also referred to as a "QR code (registered trademark)", etc.). The steel bar processing contractor reads the two-dimensional code into the steel bar processing machine, and the steel bars are processed based on the information in the two-dimensional code. Then, various processed steel bars are delivered from the steel bar processing contractor to the construction site in a determined quantity.

[0014] In each process related to the supply of such steel bars, in order to smoothly carry out the work in each process, the conversion of the expression of the steel bar dimensions and the information related to the unit of numerical values (information related to numerical representation) is carried out. The conversion of information is performed manually, and information fragmentation occurs between processes.

[0015] The manual conversion of information is carried out, for example, for the purpose of changing the numerical representation in 3D data to a numerical representation that is familiar to the workers at the construction site or the steel bar processing contractor. Conventionally, the man-hours for information conversion have occurred, resulting in high costs, and there have been cases where human errors occur or various estimated numerical values such as weight and price become inaccurate.

[0016] Therefore, the construction support system 10 described below enables seamless and low-cost work from the design to the construction of steel bars. Further, the construction support system 10 is used in the steel bar delivery support system 60 (FIG. 12). The steel bar delivery support system 60 enables the order placement and reception of steel bars via the Internet and just-in-time delivery according to the construction process related to the steel bars. First, the construction support system 10 will be described below, and then the steel bar delivery support system 60 will be described.

[0017] <Basic Configuration of Construction Support System 10> Figure 1 schematically shows the configuration of a construction support system 10 according to an embodiment of the present invention. The construction support system 10 includes a data supply unit 12, a construction unit 14, and a processing unit 16. Examples of the data supply unit 12 include information system companies and architectural design offices.

[0018] Examples of the construction unit 14 include a construction site where construction of a building to be constructed (hereinafter referred to as a "target building", etc.) is carried out. Examples of the processing unit 16 include a rebar processing company that receives an order from the construction unit 14, performs bending processing of rebars, and delivers the produced rebars to the construction unit 14.

[0019] The data supply unit 12 uses a software program for BIM (Building Information Modeling) (a construction support program, hereinafter referred to as a "BIM program") to create, as shown in Figure 1, bar arrangement drawings, summary tables, and processing ledgers from the BIM model. The data supply unit 12 also creates two-dimensional codes (also referred to as "QR codes (registered trademark)", etc.). Specific information (data) handled by the data supply unit 12 will be described later.

[0020] Figure 2 shows an example of various types of information created by the data supply unit 12. Figure 2 shows a three-dimensional model (BIM model) 22 related to the rebars of a building, a bar arrangement drawing 24 created from the three-dimensional model, and a summary table 26 created based on the bar arrangement drawing 24. The three-dimensional model 22, bar arrangement drawing 24, and summary table 26 shown in Figure 2 are merely examples. The data supply unit 12 can create various types other than those shown as the three-dimensional model 22, bar arrangement drawing 24, and summary table 26.

[0021] Figs. 3(a) and (b) show an example of a reinforcement arrangement diagram created based on this information (a building at a beam-column joint). The three-dimensional model 22 in Fig. 2 and the buildings shown in the reinforcement arrangement diagrams in Figs. 3(a) and (b) are also examples of a "project". A "project" is a model of the target building.

[0022] In the data supply unit 12, it is possible to use a general personal computer (hereinafter referred to as "PC") device as the construction support device 30 (Fig. 4). The construction support device 30 is communicably connected to the management computers (not shown) of the construction unit 14 and the processing unit 16 (Fig. 1) via a communication network (not shown). Examples of the communication network include those interconnected via, for example, the Internet, LAN, WAN, public telephone lines, base stations, mobile communication networks, and gateways (including the so-called cloud).

[0023] As shown in Fig. 4, the construction support device 30 includes a control unit 31, a storage unit 32, a communication unit 33, etc. inside, and includes an operation unit 34, a display unit 35, etc. as peripheral devices.

[0024] Although not shown in the figure, the control unit 31 is composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The CPU of the control unit 31 expands and executes various computer programs stored in the ROM and the storage unit 32 on the RAM. The control unit 31 may be any processing circuit or arithmetic circuit including a plurality of CPUs, multi-core CPUs, GPUs (Graphics Processing Units), microcontrollers, volatile or non-volatile memories, etc.

[0025] The control unit 31 includes a 3D model creation unit 36, a reinforcement drawing creation unit 37, a summary table creation unit 38, a reinforcement information calculation unit 39, a 2D code creation unit 40, and the like. The 3D model creation unit 36 creates information for the 3D model 22 shown in FIG. 2. The reinforcement drawing creation unit 37 creates information for the reinforcement drawing 24 (FIG. 2), and the summary table creation unit 38 creates information for the summary table (FIGS. 2, 9(a), (b)).

[0026] The reinforcement information calculation unit 39 performs calculations of the reinforcement information used by the 3D model creation unit 36, the reinforcement drawing creation unit 37, the summary table creation unit 38, and the 2D code creation unit 40. The 2D code creation unit 40 creates information for the 2D code displayed on the management tag (pictogram) or the like.

[0027] These units such as the 3D model creation unit 36, the reinforcement drawing creation unit 37, the summary table creation unit 38, the reinforcement information calculation unit 39, and the 2D code creation unit 40 are functional modules executed by the CPU of the control unit 31 according to the BIM program. Among these functional modules, the details of the summary table creation unit 38, the reinforcement information calculation unit 39, and the 2D code creation unit 40 will be described later.

[0028] The storage unit 32 is a non-volatile storage unit including a semiconductor memory such as a ROM or a RAM that stores various types of information, an HDD (Hard Disk Drive), or an SSD (Solid State Drive). The storage unit 32 stores an operating system program, a driver program, an application program, data, and the like used in the processing by the processor (here, the control unit 31).

[0029] The program stored in the memory unit 32 may be provided by a non-transitory recording medium (not shown) that stores the program in a readable manner. Examples of the recording medium include portable memories such as CD-ROM, USB (Universal Serial Bus) memory, SD (Secure Digital) card, micro SD card, and CompactFlash (registered trademark). In this case, the control unit 31 reads the program from the recording medium using a reading device (not shown) and installs the read program in the memory unit 32.

[0030] The program stored in the memory unit 32 may be provided by communication via the communication unit 33. In this case, the control unit 31 acquires the program through the communication unit 33 and installs the acquired program in the memory unit 32.

[0031] The communication unit 33 includes an interface circuit for communicating with a management computer (not shown) of the construction unit 14 (FIG. 1) through a communication network. The communication unit 33 performs wired or wireless data communication according to a predetermined communication protocol. For example, when information to be transmitted to the construction unit 14 is input from the control unit 31, the communication unit 33 transmits the input information to the construction unit 14. The communication unit 33 outputs information from the construction unit 14 received through the communication network to the control unit 31.

[0032] An operation unit 34 and a display unit 35 are connected to the construction support device 30. The operation unit 34 is operation input means such as a keyboard, a mouse, and a touch panel. Although only one operation unit 34 is shown in FIG. 4, the operation unit 34 comprehensively shows these operation input means. The display unit 35 is display means such as a general display device.

[0033] Note that a general PC can also be adopted as the management computer (not shown) of the construction department 14 (Fig. 1). Also in the processing department 16 (Fig. 1), communication with the construction department 14 via a communication network is performed using a management computer (not shown). As the management computers of the construction department 14 and the processing department 16, those having the same hardware configuration as the construction support device 30 can be adopted.

[0034] In the control unit 31 related to the construction support device 30 (Fig. 4) of the data supply unit 12, the reinforcing bar information calculation unit 39 has a function (described later) of performing various calculations related to the reinforcing bar. Also, the reinforcing bar information calculation unit 39 has functions such as, for example, rounding of numerical values, truncation of numerical values, and numerical value conversion between units of millimeters, centimeters, and meters. Furthermore, the reinforcing bar information calculation unit 39 also has functions of calculating the length of the reinforcing bar and calculating the weight and estimated price of the reinforcing bar from the length of the reinforcing bar. The reinforcing bar information calculation unit 39 may perform numerical calculations using a spreadsheet software program (hereinafter referred to as "spreadsheet software") installed in the construction support device 30.

[0035] The two-dimensional code creation unit 40 creates a two-dimensional code based on the information of the reinforcing bar obtained by the reinforcing bar information calculation unit 39. The two-dimensional code includes information on the dimensions of each part of the reinforcing bar for the purpose of production. The two-dimensional code is transmitted to the processing department 16 via the construction department 14 and is read by the reinforcing bar processing machine (reference numeral 17 in Fig. 1) in the processing department 16. The reinforcing bar processing machine 17 performs bending processing on the straight reinforcing bar before processing to produce a reinforcing bar with the desired shape and dimensions. Here, the reinforcing bar processing machine 17 in Fig. 1 is merely shown as an icon and does not specifically represent the configuration of the reinforcing bar processing machine 17 actually used in the processing department 16.

[0036] Also, the control unit 31 has various functions other than the functions of the reinforcing bar information calculation unit 39 and the two-dimensional code creation unit 40. Here, the description thereof is omitted.

[0037] <Hierarchical Structure of Reinforcing Bar Object> FIG. 5 shows an example of a reinforcing bar object handled on a BIM program. In the BIM program, reinforcing bars are classified by shape, and each classification constitutes a "family". The reinforcing bar object shown in the example of FIG. 5 is classified into the "family" of reinforcing bars having a U-shaped form in hiragana.

[0038] The above-mentioned "family" means one layer in various types of information having a hierarchical structure. In the BIM program of the present embodiment, the model of the target building is defined as a "project", and under this "project", each layer such as "category", "family", and "type" is defined.

[0039] Among these layers, the "category" is the relatively highest layer, and the "type" is the relatively lowest layer. The "family" is a layer positioned between the "category" and the "type".

[0040] For example, classifications such as "column", "wall", and "window" are defined in the "category". Further, in the "category" of "column", "families" such as "circular column" and "rectangular column" are defined.

[0041] In the "family" of "circular column", "types" such as "circular column (diameter 450 mm)" and "circular column (diameter 600 mm)" are defined. In the "family" of "rectangular column", "types" such as "rectangular column (450 mm × 600 mm)" and "rectangular column (600 mm × 750 mm)" are defined.

[0042] In the present embodiment, the "category" of "reinforcing bar" is created. In the "category" of "reinforcing bar", a plurality of types of "families" related to U-shaped, square-shaped, or other-shaped reinforcing bars are defined. And for various "families", a variety of "types" with different sizes of common parts are defined.

[0043] In the BIM program, various "categories", "families", and "types" are defined in addition to these. Information on objects related to various "categories", "families", and "types" is called from the storage unit 32 (Figure 4) and used. Also, it is possible for the operator of the BIM program to add "categories", "families", and "types" that are not registered in the library in advance to the library as needed.

[0044] For example, the "families" include types such as "system family", "in-place family", and "nestable family". Among these, the "system family" is the basic family, and it corresponds to walls, floors, roofs, ceilings, and stairs, etc.

[0045] The "in-place family" is a family in which the operator can change the shape of the object. The "loadable family" is a family that is created individually and loaded from the library into the project file (project file) and used. It corresponds to windows, doors, furniture, equipment, etc. of a specific building material manufacturer. It is possible to create parts that constitute a unique design in a building using the "in-place family", and create general parts that can be used in multiple buildings using the "loadable family", and so on.

[0046] The functions of such multiple types of families may be provided in conventional general-purpose BIM programs. However, the inventors have defined new parameters for the rebar object that are not conventional, making the BIM program even more effective. This will be described below.

[0047] <Parameters of the rebar object> In the example of Fig. 5, for rebar objects (hereinafter referred to as "rebar objects") that belong to the same classification (corresponding to the "U-shaped" "family" here) and have different sizes (corresponding to "type"), information on "number", "diameter", "shape", "dimension a", "dimension b", "dimension c", "dimension d", "dimension e", "length of rebar", "unit weight", "weight per piece", "number of pieces", and "rebar weight" is shown.

[0048] The rebar object is given detailed length information (such as "dimension a", "dimension b", "dimension c", "dimension d", and "dimension e") that determines the information on the rebar diameter (diameter), weight, and shape. In the example of Fig. 5, dimension a is the length of the straight-line part (hereinafter referred to as the "central straight-line part") that constitutes the central part in Fig. 5.

[0049] Dimension b and dimension d are the lengths of the straight-line parts (hereinafter referred to as the "left straight-line part" and "right straight-line part") located on the left and right sides of the central straight-line part in Fig. 5. Dimension c and dimension e are the lengths of the arc-shaped parts (hereinafter referred to as the "bending parts") that connect the central straight-line part and the left and right straight-line parts in Fig. 5.

[0050] In the example of Fig. 5, three types of rebar objects (F1 to F3) with different dimension a or dimension b are shown. The various information related to the rebar objects (here F1 to F3) functions as parameters. By the operator changing the various information related to the rebar objects (here F1 to F3), the value of the corresponding parameter is rewritten and the type of the rebar object is changed.

[0051] <Example of parameter input> Fig. 6 shows an example of the screen display during the input operation related to the parameters of the rebar object. On the left side of Fig. 6, a U-shaped rebar object 42A is displayed. The "defined parameters" and arrows shown for the rebar object 42A are added for the purpose of explaining this embodiment.

[0052] Regarding the reinforcing bar object 42A, as indicated by the characters and arrows of "defined parameters", when the operator inputs the dimensions of the straight portions (the portions a to c), various parameters including the information on the bent portion (hereinafter referred to as "bent portion information") are automatically calculated and displayed in the parameter table 42B shown on the right side of FIG. 6.

[0053] In the example of FIG. 6, for the straight portions of the reinforcing bar object 42A, the numerical values of a (the dimension of the a portion) = 1200 [mm], b (the dimension of the b portion) = 600 [mm], and c (the dimension of the c portion) = 1200 [mm] are input. Along with this, in the parameter table 42B, in addition to the input dimensions of a to c, bent portion information such as the bending diameter (the radius of the arc in the bent portion) and straight portion information related to the straight portions are displayed. Here, in the example of FIG. 6, different from the example of FIG. 5, the c portion is the left straight portion.

[0054] The input dimension value is the sum of the straight portion and the bent portion. In the example of FIG. 6, the reinforcing bar diameter is 10 [mm], and the bending diameter calculated based on this reinforcing bar diameter is 27.6 [mm]. When the dimension value of 1200 [mm] is input for the a portion, the breakdown of the dimension of the a portion is the exact length in millimeters (hereinafter referred to as "mm unit", with one decimal place after the decimal point) of the bending diameter + the straight portion + the bending diameter. Specifically, the breakdown of the dimension of the a portion is 27.6 [mm] + 1144.8 [mm] + 27.6 [mm] = 1200 [mm].

[0055] In this way, by inputting the dimension value including the bending diameter (here 1200 [mm]) as the dimension value of the straight portion, the dimension of the straight portion in mm unit (straight portion information) and the bent portion information such as the bending diameter are distinguished, and various parameter calculations are performed.

[0056] Note that here, the U-shaped reinforcing bar object 42A is taken as an example, but for other families of reinforcing bar objects (not shown), by inputting the dimension of the straight portion, the straight portion information and the bent portion information in mm unit are calculated.

[0057] In a BIM program, the values of parameters can be freely changed. Also, it is possible to perform operations between parameters (such as addition, subtraction, multiplication, and division operations, operations of functions including parameters, etc.). Further, the BIM program creates various information of a reinforcing bar object using new parameters. Moreover, the BIM program aggregates various information based on the created information.

[0058] <New parameters> The BIM program in this embodiment has a function of performing calculations of the length and weight of a reinforcing bar using the center dimension (described later) of a reinforcing bar having a bent portion (also referred to as a "bent reinforcing bar"). The construction support method of this embodiment performed using the BIM program uses, as parameters related to the 3D model of the bent reinforcing bar, the center dimension information in millimeters of the bent reinforcing bar and the outer dimension information in a unit larger than millimeters (here, centimeter unit), and includes a 3D model information creation step of creating 3D model information related to the 3D model, and a reinforcing bar manufacturing information creation step of creating reinforcing bar manufacturing information based on the 3D model information. At least in the 3D model information creation step, 3D model information is created including the center dimension information.

[0059] "Center dimension information" corresponds to information representing the dimension (length) of a portion along the center line of the reinforcing bar (such as the center line C in Fig. 7(a)) as described later. "Outer dimension information" corresponds to information representing the dimension (length) of a portion along the outer surface of the reinforcing bar (such as the outer surface 47 in Fig. 7(b)). "3D model information" corresponds to information of the 3D model of the bent reinforcing bar (such as the information of the bent reinforcing bar shown in the summary table in Fig. 9(b)). The "3D model information creation step" is a step of creating "3D model information". "Reinforcing bar manufacturing information" corresponds to information created based on the "3D model information" (such as a 2D code and information used for creating the 2D code). The "reinforcing bar manufacturing information creation step" is a step of creating "reinforcing bar manufacturing information". The figures after Fig. 7 will be described later.

[0060] Further, in the construction support method of the present embodiment, at least in the reinforcing bar manufacturing information creation step, the reinforcing bar manufacturing information is created including the outer dimension information, and the reinforcing bar manufacturing information output step of converting the reinforcing bar manufacturing information into a readable code (such as a two-dimensional code) that can be read by a reading device (such as an optical two-dimensional code reader) and outputting it is provided.

[0061] Furthermore, the construction support method of the present embodiment includes a length calculation step of calculating the length information of the bent reinforcing bar using the center dimension information, and a weight calculation step of calculating the weight information of the bent reinforcing bar based on the length information. The "length information of the bent reinforcing bar" is information representing the length (total length) of the reinforcing bar. The "weight information of the bent reinforcing bar" is information representing the weight of the reinforcing bar.

[0062] The new parameter defined in the present embodiment is information regarding the center dimension of the bent portion (the c portion and the e portion in the example of FIG. 5) in the reinforcing bar object. Specifically, the new parameter is various information such as the center dimension in millimeters related to the bent portion, the length of the reinforcing bar calculated using this center dimension, and the weight.

[0063] The bending diameter, which is one of the bent portion information, is calculated as a value using the center dimension of the reinforcing bar. FIG. 7(a) schematically shows the center dimension in a U-shaped reinforcing bar object. In the example of FIG. 7(a), the center dimension is represented by the length of the center line C by a dashed-dotted line, rather than specific numerical values or symbols.

[0064] In the example of FIG. 7(a), the reinforcing bar object 46 is composed of a central straight portion (a portion), left and right straight portions (b portion, d portion), and bent portions (c portion, e portion). The center dimension can be said to be the length of a virtual line (center line C) passing through the center of the reinforcing bar object when assuming the reinforcing bar diameter of the reinforcing bar object 46.

[0065] The dimension (outer surface dimension) of the surface (outer surface) 47 outside the center line C in the reinforcing bar object 46 is a dimension outside the center dimension and has a value larger than the center dimension. FIG. 7(b) schematically shows the outer surface 47 by a thick line 47a. The outer surface dimension is represented by the length of the thick line 47a indicating the outer surface 47. The reinforcing bar object 46 illustrated here has a substantially circular cross section. For this reason, the outer surface 47 in FIG. 7(b) corresponds to a ridge line outside the center line C.

[0066] In FIG. 7(b), the surface (inner surface) 48 inside the center line C in the reinforcing bar object 46 is schematically shown by a thick line 48a. The dimension (inner surface dimension) of the inner surface 48 is represented by the length of the thick line 48a indicating the inner surface 48. The inner surface 48 corresponds to a ridge line inside the center line C.

[0067] The outer surface 47 is located outside the center line C. For this reason, the outer surface dimension is larger (longer) than the center dimension. Also, the inner surface 48 is located outside the center line C. For this reason, the inner surface dimension is smaller (shorter) than the center dimension.

[0068] FIG. 8(a) shows an enlarged view of one bent portion (c portion) in the reinforcing bar object 46. The length of the bent portion is defined as the length of the center line Cc in the bent portion. The length (total length) of the reinforcing bar object 46 is defined as the length of the center line C. As shown in FIG. 8(b), the length (total length) of the reinforcing bar object 46 is represented by the sum of the length of the center line Ca in the central straight portion, the lengths of the center lines Cb and Cd in the left and right side portions, and the lengths of the center lines Cc and Ce in the two bent portions.

[0069] The length of the bent portion (the length of the center line Cc which is the center dimension and / or the length of the center line Ce) is one piece of bent portion information. In the present embodiment, it is possible to create a tabulation form (FIG. 9(a)) not including the bent portion information and a tabulation form (FIG. 9(b)) including the bent portion information by the function of the tabulation form creation unit 38.

[0070] Fig. 9(a) shows an example of a summary table when bending part information is not included. In the example of Fig. 9(a), the "number" representing the reinforcing bar object having the same shape as the reinforcing bar object 42A in Fig. 6 is "F2", and the "shape" of this F2 reinforcing bar object is represented by "C-1".

[0071] Also in Fig. 5, the symbol F2 is used. Fig. 5 shows information of a reinforcing bar object different from the reinforcing bar object shown in Fig. 9(a). Therefore, even though the symbols used are common, the dimensions of each part are different between the F2 reinforcing bar object in Fig. 9(a) and the F2 reinforcing bar object in Fig. 5.

[0072] Regarding the reinforcing bar object in Fig. 9(a) (hereinafter referred to as "reinforcing bar object F2"), the dimension of part a is a = 500 [mm]. Further, the dimensions of parts b and c which are the left and right straight parts are b = 150 [mm] and c = 150 [mm]. On the other hand, in the reinforcing bar object F2 of Fig. 5, the dimensions of the corresponding part a, part b, and part d are 8,036 [mm], 673 [mm], and 1,740 [mm]. Also, in Fig. 5, parts c and e which are bending parts are defined, but in Fig. 9(a), no bending part is defined.

[0073] In the reinforcing bar object F2 of the summary table in Fig. 9(a), the "length of the reinforcing bar" is 750 [mm]. The value of a + b + c related to the reinforcing bar object F2 is 800 (= 500 + 150 + 150) [mm]. However, in the summary table of Fig. 9(a), the reason why the "length of the reinforcing bar" is 750 [mm] is that the ease of work when using the summary table of Fig. 9(a) at the construction site is considered.

[0074] That is, at the construction site, it is normal to use centimeters (cm) as the unit of length. In other words, at the construction site, the unit used for information sharing and communication among related parties is centimeters.

[0075] Therefore, even if the exact length of the required reinforcing bar in millimeters (millimeter unit) is, for example, 741 [mm], the value handled at the construction site is 750 [mm] (= 75 [cm]), which is the value obtained by rounding up the unit of mm. Also, if the value handled at the construction site is rounded down to, for example, 740 [mm] (= 74 [cm]), it is possible that there will be a shortage in the length of the reinforcing bar or a deficiency in strength. Therefore, it is normal to adopt the rounded-up value.

[0076] From these facts, in the tabulation of the example in Fig. 9(a), the value of 750 [mm] is displayed as the "length of the reinforcing bar" related to the reinforcing bar object F2.

[0077] The value of 750 [mm] related to this "length of the reinforcing bar" is obtained by rounding up so that the end of the value in millimeters becomes 0 (zero). Therefore, the person concerned at the construction site can perform the conversion from millimeters to centimeters (centimeter unit) by mentally calculating the operation of dividing the value of 750 [mm] by 10. Therefore, at the construction site, the conversion from millimeters to centimeters is easy.

[0078] Also, the relationship between the numerical values of a = 500 [mm], b = 150 [mm], d = 150 [mm] related to the reinforcing bar object F2 in Fig. 9(a) and the numerical value of 750 [mm] of the "length of the reinforcing bar" is also determined in consideration of the ease of work at the construction site.

[0079] Specifically, at the construction site, a single straight reinforcing bar is hung on a reinforcing bar processing machine (hereinafter referred to as a "bending processing machine") and processed. As the bending processing machine, various general types can be used. When manufacturing a U-shaped reinforcing bar based on the numerical values related to the reinforcing bar object F2 in Fig. 9(a), the processing operation of the reinforcing bar is performed so that the a part, b part, and d part become 500 [mm] (= 50 [cm]), 150 [mm] (= 15 [cm]), and 150 [mm] (= 15 [cm]), respectively.

[0080] Figure 10 schematically shows the information necessary for the operator performing the processing operation. Comparing Figure 10 with Figure 7(a), in Figure 10, the arc-shaped bending portions (portions c and e) in Figure 7(a) are changed to right angles. As shown in Figure 10, if the operator recognizes the dimensions including the bending portions (portions c and e) in Figure 7(a) as straight portions (portions a to c) and performs the processing operation, the reinforcing bar of the target type can be produced. And the numerical values used by the operator at the construction site during the operation are the numerical values of the outer dimensions.

[0081] As described above, the value of the outer dimension is larger than the center dimension. Also, consider a reinforcing bar object 46A in which the bending portions (portions c and e) of the reinforcing bar object 46 shown in Figure 7(a) are changed to a right angle shape and the bending portions are linearized as shown in Figure 10. For this reinforcing bar object 46A, the length of the reinforcing bar (outer dimension, center dimension, and inner dimension) is longer than that of the reinforcing bar object 46 in Figure 7(a) with arc-shaped bending portions.

[0082] In the tabulation in Figure 9(a), portions a, b, and d are 500 [mm], 150 [mm], and 150 [mm] respectively. Summing these numerical values gives 800 (= 500 + 150 + 150) [mm].

[0083] However, the operator at the construction site prepares a straight reinforcing bar (unprocessed reinforcing bar) of 750 [mm] (= 75 [cm]) according to the numerical value of "length of the reinforcing bar" in the tabulation in Figure 9(a). Furthermore, the operator at the construction site performs the processing operation so that the outer dimensions of portions a, b, and d are 50 [cm], 15 [cm], and 15 [cm] respectively. As a result, a U-shaped reinforcing bar is produced that is shorter than 800 [mm], which is the total value of portions a, b, and d on the tabulation, and further shorter than the numerical value of "length of the reinforcing bar", as the actual length of the reinforcing bar (total length based on the center dimension).

[0084] Thus, the information on the numerical value of 750 [mm] in the "Length of Reinforcement Bars" in the summary table of Fig. 9(a) was created considering the ease of work at the construction site. And in the summary table of Fig. 9(a), considering the length of the bent part (the length of the bent part based on the center dimension) calculated based on a predetermined mathematical formula, the values of part a, part b, and part d are calculated to be enlarged compared to the actual length of each part in the reinforcement bars to be produced.

[0085] The summary table of Fig. 9(b) shows a summary table that displays more accurate dimension information compared to the summary table of Fig. 9(a) which prioritizes convenience at the construction site. In the example of Fig. 9(b), the "Shape" related to the reinforcement bar object F2 in Fig. 9(a) is "C-1", the same as in Fig. 9(a). Hereinafter, the reinforcement bar object in Fig. 9(b) where the symbol of "Shape" is displayed as "C-1" will be referred to as "Reinforcement Bar Object C-1" to distinguish it from the reinforcement bar object F2 related to the summary table of Fig. 9(a).

[0086] In the summary table of Fig. 9(b), the symbols a~e assigned to each part of the reinforcement bar object C-1 are the same as the symbol assignment shown in Fig. 5. Specifically, the central straight part is part a, and the left and right straight parts are part b and part d. Also, the bent parts are part c and part e.

[0087] In the summary table of the example of Fig. 9(b), the dimension of part a of the reinforcement bar object C-1 is a = 409 [mm]. Furthermore, the dimensions of part b and part d of the reinforcement bar object C-1 are b = 105 [mm], d = 105 [mm]. The dimensions of part c and part e which are the bent parts are c = 61 [mm], e = 61 [mm].

[0088] The following formula (1) is used to calculate the length of the bent parts (part b and part d) in the family of the reinforcement bar object C-1. In the example of Fig. 9(b), the reinforcement bar diameter (diameter) which is the "diameter" of the reinforcement bar object C-1 is 13 [mm]. (Length of the bent part) = 1.5 × π (pi) × (Reinforcement bar diameter) ··· Formula (1)

[0089] When substituting the value of 13 "mm" for the "diameter" into Equation (1), the length of the bent part (the length of part b = the length of part d) is 1.5×π(=3.14)×13 = approximately 61.23. Rounding off the decimal part of the obtained value, the value becomes 61 [mm], and this value is displayed in the "c" column and "e" column in the summary table of Fig. 9(b).

[0090] Note that the mathematical formula for calculating the length of the bent part (the length of part c and part d) may vary depending on the family of steel bars.

[0091] In the example of Fig. 9(b), the value of a + b + c + d + e in the steel bar object C-1 is 741 (=409 + 105 + 61 + 105 + 61) [mm]. For this numerical value of 741 [mm] in the calculation, the display of the "length of the steel bar" is 750 [mm]. This is the numerical value obtained by rounding up the numerical value of the "length of the steel bar" in the calculation so that the end of the numerical value in millimeters becomes 0 (zero).

[0092] In this way, by using the numerical values of the bent parts displayed in the summary table of Fig. 9(b), a more accurate "length of the steel bar" is calculated. The information on the bent parts (part c, part e) (bent part information) is obtained by incorporating a routine for performing calculations using a mathematical formula such as Equation 1 into the BIM program, and having the steel bar information calculation unit 39 (Fig. 4) perform the calculations.

[0093] In the BIM program, mathematical formulas for the bent parts of various families of steel bars are described. For example, when the designer selects a family and inputs the value of the "diameter", the bent part information is calculated. Then, by inputting the values of other parameters (the lengths of part a, part b, and part d) related to the steel bar object (here, the steel bar object C-1), a more accurate "length of the steel bar" is calculated.

[0094] The BIM program calculates information on various rebar objects (3D model information, rebar fabrication information, center dimension information, outer dimension information, etc.) by the method described above. Further, the BIM program combines information on various rebar objects and information on other "categories" to create a 3D model (Figure 2) of the project.

[0095] To accurately calculate or display the length of the rebar, it is effective to perform calculations based on the center dimensions as in this embodiment. However, at the construction site related to the construction section 14 (Figure 1), the operation of calculating the distance from the center line by halving the rebar diameter and then subtracting or adding the calculated value to the dimensions given in the summary table or the like to accurately determine the required length of the rebar is troublesome for the operator and causes a decrease in work efficiency. Therefore, it is difficult to perform operations based on the center dimensions of the rebar at the construction site, and operations based on the outer dimensions, which can be relatively easily performed, are carried out.

[0096] Also, if the summary table (Figure 9(a)) provided at the construction site shows that construction must be carried out considering the length of the bent part, complicated confirmation work using the rebar diameter and pi is required at the construction site, increasing the possibility of human error.

[0097] Furthermore, in the reinforcement layout drawing (Figure 2) that serves as the basis for creating the summary table, the bent part is often not shown in the drawing. Also, in the 3D model, it may be hidden in the projection direction and not visible unless the viewpoint of the 3D model is changed. Therefore, it is difficult to calculate the center dimensions of the bent part retrospectively.

[0098] However, by generating information on rebar objects with the center dimensions of the bent part as parameters in the data supply unit 12, which is the most upstream of the information, as in the construction support system 10 of this embodiment, it is possible to create accurate information on rebar objects in a unified manner without calculating the dimensions of the bent part from the 3D model or calculating the dimensions of the bent part by the rebar fabricator.

[0099] <Use of two-dimensional code> The BIM program converts the information of the reinforcing bar object into a two-dimensional code for operating the bending machine. The two-dimensional code created by the BIM program is printed on the management tag (pictogram) and attached (or pasted) to the straight bar-shaped reinforcing bar product before bending. The two-dimensional code printed on the management tag is read by, for example, an optical two-dimensional code reader and input into the bending machine as processing information. The bending machine operates based on the input processing information to bend the straight bar-shaped reinforcing bar and produce a reinforcing bar with the desired shape.

[0100] <Estimation of weight and price> Furthermore, as shown in the summary table of the example in Fig. 9(b), the BIM program calculates the weight of the reinforcing bar using the information of "length of the reinforcing bar" and "diameter" including the length information of the bent part based on the center dimension. The weight of the reinforcing bar can be obtained by the following formula (2). The specific gravity of the steel, which is the material of the reinforcing bar, is about 7.85. π / 4×(diameter [mm]) 2 ×(length of the reinforcing bar [mm])×(specific gravity of the material of the reinforcing bar)×10 6 ···Formula (2)

[0101] Such calculation of the weight of the reinforcing bar can be performed for all the reinforcing bars used in the 3D model. Therefore, by calculating and summing up the weights of all the reinforcing bars targeted for weight calculation, the total weight of a plurality of reinforcing bars can be calculated. Also, by calculating the product of the calculated weight and the unit price of the material (price per unit weight), it is possible to calculate the price of the target reinforcing bar. And since these calculations are performed using accurate bent part information, it is possible to calculate a more accurate estimated weight and estimated price.

[0102] <Classification of reinforcing bar objects based on the tolerance of change> The BIM program in this embodiment has a function of calculating the length and weight of reinforcing bars using the center dimensions of bent reinforcing bars (Fig. 7(a)). It can handle multiple types of reinforcing bar objects with different allowable tolerances for dimension changes.

[0103] Figs. 11(a) to (c) schematically show the classification of reinforcing bar objects based on the allowable tolerance. In the construction support method performed using the BIM program in this embodiment, as shown in Fig. 11(a), the 3D model of the bent reinforcing bars includes a first bent reinforcing bar family and a second bent reinforcing bar family that can form a project.

[0104] A "project" is a model of the target building. The "first bent reinforcing bar family" and the "second bent reinforcing bar family" are families that are classified into different families among the families related to bent reinforcing bars.

[0105] As shown in Fig. 11(b), the first bent reinforcing bar family is shared among multiple projects. In Fig. 11(b), the first bent reinforcing bar information 1 is commonly used in Project 1 and Project 2, which are different projects. For example, in the project of the beam-column joint shown in Fig. 3(a) (or the beam-column joint shown in Fig. 3(a)), when the same U-shaped reinforcing bar (for example, the reinforcing bar shown in Fig. 7(a)) is used, it corresponds to the case where the first bent reinforcing bar family is shared among multiple projects. The "second bent reinforcing bar family" may include those that cannot be shared among multiple projects.

[0106] "The first bent reinforcing bar information 1" means one of the first bent reinforcing bar information included in the first bent reinforcing bar family. That is, as shown in Fig. 11(a), the first bent reinforcing bar family includes at least one piece of first bent reinforcing bar information related to bent reinforcing bars. In the example of Fig. 11(a), the first bent reinforcing bar family includes the first bent reinforcing bar information 1 to the first bent reinforcing bar information 3. The number of types of the first bent reinforcing bar information may be two or less, or four or more.

[0107] The second bent bar family also includes second bent bar information related to at least one bent bar. In the example of Fig. 11(a), the second bent bar family includes second bent bar information 1 to second bent bar information 3. The number of types of the second bent bar information may be two or less, or may be four or more.

[0108] Regarding the first bent bar information (in the example of Fig. 11(a), the first bent bar information 1 to the first bent bar information 3), the center dimension of the bent portion in the bent bar can be set within a range restricted by a mathematical formula based on the bar diameter.

[0109] The "center dimension of the bent portion" is the center dimension (such as the length of the center line Cc and the length of the center line Ce in Fig. 8(b)) in the bent portion (such as the c portion and the e portion in Fig. 7(a)) of the bent bar. The "mathematical formula based on the bar diameter" is a mathematical formula (such as "(length of the bent portion) = 1.5 × π (pi) × (bar diameter)" in Equation (1)) with the bar diameter as a parameter. "Can be set within a range restricted by the mathematical formula" means being restricted within a range obtained by substituting arbitrary values into the parameters (such as the bar diameter) of various mathematical formulas.

[0110] Regarding the second bent bar information, the center dimension of the bent portion in the bent bar can be set arbitrarily. "The center dimension of the bent portion can be set arbitrarily" means that the center dimension of the bent portion can be defined by arbitrarily inputting a numerical value without being restricted by a predetermined mathematical formula (such as Equation (1)). It is possible to directly input the value of the "center dimension of the bent portion" arbitrarily.

[0111] The mathematical formula (such as Equation (1)) includes at least pi (π) as a constant, and pi is used up to at least two decimal places (up to 3.14).

[0112] Regarding the project related to the first bent rebar family, for example, while displaying on the screen, the dimension of the straight part (straight portion) of the rebar (first bent rebar information) in the rebar arrangement diagram shown in Fig. 3(a) (or Fig. 3(b)) can be arbitrarily changed by dragging it via mouse operation. Also, for example, the dimension of the straight part (straight portion) of the rebar object 42A as shown in Fig. 6 can be arbitrarily changed by dragging it via mouse operation or by inputting the numerical value of the straight part into the parameter table 42B. However, the length dimension of the bent part cannot be changed from the range restricted by the said formula. The formula varies depending on the difference in the rebar diameter.

[0113] The "project related to the first bent rebar family" is a plurality of projects that can share the first bent rebar family (in the example of Fig. 11(a), the first bent rebar information 1 to the first bent rebar information 3). "While displaying on the screen" means while displaying on the display unit 35 (Fig. 4) etc. so that the content of the modeling can be visually recognized. The "straight part" is the straight portion of the rebar (such as the a part, b part, d part in Fig. 7(a)).

[0114] "Arbitrarily changing" the dimension of the straight part (straight portion) means stretching or expanding the dimension (length) of the "straight part" to an arbitrary value without being restricted by a formula (such as formula (1)). The "length dimension of the bent part" means the length dimension represented by the center dimension of the bent part. "The length dimension of the bent part cannot be changed from the range restricted by the said formula" means that regarding the project part related to the first bent rebar family, the length of the straight part can be arbitrarily changed, but the length dimension of the bent part is restricted by the formula.

[0115] <Advantages of the invention related to the construction support system 10> According to the construction support system 10 of the present embodiment as described above, the information of the reinforcing bar object (here, the reinforcing bar manufacturing information, the outer dimension information, etc.) created by the BIM program in the data supply unit 12 is used in the construction unit 14 and the processing unit 16. Further, the information of the reinforcing bar object is supplied after being adjusted to the values and units required by the data supply unit 12, the construction unit 14, and the processing unit 16, respectively.

[0116] The dimensions of the bent portion can be represented by the center dimension in the data supply unit 12 (FIG. 1). And the length of the reinforcing bar is represented by a numerical value including the center dimension of the bent portion. For this reason, the information of the length of the reinforcing bar can be accurately represented, and accurate information regarding the length of the reinforcing bar can be provided to the construction unit 14. Therefore, it becomes possible to provide accurate information based on the center dimension.

[0117] Also, from the data supply unit 12, it is possible to provide the construction unit 14 with the information represented by the center dimension and the information represented by the outer dimension regarding the length of the reinforcing bar. Therefore, in the construction unit 14 and the processing unit 16, the work of manually converting the information acquired from the upstream into the necessary information becomes unnecessary. And from the design to the manufacture of the reinforcing bar, a consistent data exchange without human error becomes possible.

[0118] Also, the information of the reinforcing bar object created in the data supply unit 12 includes the information of the length of the bent portion calculated in millimeters. For this reason, based on the accurate information regarding the length of the reinforcing bar, it is possible to accurately perform various simulations. For example, it becomes possible to accurately perform the interference check between the reinforcing bars in the reinforcing bar arrangement drawing (for example, FIGS. 3(a) and (b)) and various estimates regarding the reinforcing bar. An accurate estimate can be performed in the data supply unit 12. Also, by providing the construction unit 14 with accurate information regarding the length of the reinforcing bar from the data supply unit 12, it is also possible to perform an accurate estimate in the construction unit 14. Therefore, there is no need to place an order that may include an excessive surplus from the construction unit 14 to the processing unit 16, and cost reduction becomes possible.

[0119] In addition, as shown in FIGS. 11(a) to 11(c), since different types of reinforcing bar objects can be created depending on the allowable degree of change, three-dimensional models can be created in various ways.

[0120] From these aspects, according to the invention related to the construction support method, construction support program, and construction support device 30 of the present embodiment, it is possible to develop the digital twin concept that reproduces the real space on the virtual space (digital space) into a more useful and practical one.

[0121] Note that the above-described embodiment is merely an example of the implementation in carrying out the invention related to the construction support system 10, and the technical scope of the invention should not be construed in a limited manner thereby. That is, the invention related to the construction support system 10 can be implemented in various forms without departing from the gist or the main features thereof.

[0122] For example, in the example of FIG. 1, various types of information (such as information on processing sheets and two-dimensional codes) are provided from the data supply unit 12 to the processing unit 16 via the construction unit 14, but various types of information may be provided from the data supply unit 12 directly to the processing unit 16 without passing through the construction unit 14.

[0123] <Reinforcing bar delivery support system 60> Next, a reinforcing bar delivery support system (such as the reinforcing bar delivery support system 60 shown in FIG. 12) using the invention related to the construction support system 10 will be described. One aspect (also referred to as a side view) of the reinforcing bar delivery support system is a reinforcing bar delivery support system used for delivering reinforcing bars used in the construction of a building to the construction site, and creates reinforcing bar processing information related to the processing of the reinforcing bars from a bar arrangement drawing showing the arrangement of the reinforcing bars, and is a reinforcing bar delivery support system that processes the reinforcing bars required at a plurality of construction times defined stepwise in a construction schedule based on the reinforcing bar processing information and delivers them to the construction site.

[0124] As long as it is constructed using steel bars, various things can be applied as the "building". The "reinforcement drawing" is a drawing showing the arrangement of steel bars in a reinforced concrete member, and is also called a detailed reinforcement drawing. An example of a reinforcement drawing is shown in Fig. 13. In the example of Fig. 13, reference numeral 62 indicates the building structure. Reference numeral 64 indicates the main bars, and reference numeral 66 indicates the stirrups.

[0125] The reinforcement drawing is drawn as one of the structural drawings. Generally, the scale of the reinforcement drawing is about 1 / 50 to 1 / 5. Also, when the scale is small and the drawing is detailed (when the scale is about 1 / 50 to 1 / 30), it is generally not expressed the bar diameter. And when creating the reinforcement drawing, the creator often draws the steel bars with "lines and symbols" without showing the bar diameter while having an image of the bar diameter in mind. Here, for the processing of steel bars, information such as the length (total length) of the steel bar before processing, the diameter of the steel bar, and the radius of the bent part (processing required information) is required, but these information are not specifically described or not described in an easy-to-recognize manner. This is the same for both the so-called design drawings and general drawings.

[0126] The reinforcement drawing is often created at the places where the steel bars intersect in the structure (the joint parts of each member). Specifically, examples include the joint between the column and the beam, the joint between the beam and the additional slab, and the joint between the beam and the slab.

[0127] There are multiple types of reinforcement drawings, such as the reinforcement drawing as a structural design drawing and the reinforcement drawing as a construction drawing. The reinforcement drawing as a construction drawing may be created with a scale of 1 / 1. The reinforcement drawing in this embodiment may be any type of reinforcement drawing. However, the more information lacking in the steel bar processing, the more difficult it is to determine information such as the shape of the steel bar based on the reinforcement drawing.

[0128] Here, as shown in the reinforcement drawing creation unit 37 of the construction support device 30 (Fig. 4) of the construction support system 10, a function for creating a reinforcement drawing is provided. However, as shown in Fig. 2, the reinforcement drawing created by the construction support device 30 is created based on a 3D model (created reinforcement drawing). On the other hand, the reinforcement drawing used in the rebar incorporation support system 60 is a reinforcement drawing (received reinforcement drawing) provided by the construction supervisor or the like. In the rebar incorporation support system 60, information such as the diameter, shape, and number of rebars is determined based on the reinforcement drawing (received reinforcement drawing). Then, based on the determined information, a 3D model (3D model information) is created. In the rebar incorporation support system 60, it is possible to use the construction support device 30 (Fig. 4) of the construction support system 10. In this case, the construction support device 30 (Fig. 4) functions as a rebar incorporation support device. The creation of the 3D model can be performed manually by the operator of the construction support device 30 or can be automated. Regarding the creation of the 3D model by automation, the method for creating 3D model information by automation will be described later.

[0129] "Reinforcement processing" means, for example, bending a straight bar-shaped reinforcement to change the shape of the reinforcement into various shapes required for the construction of a building.

[0130] "Reinforcement processing information" is information required to process the reinforcement into the target shape, which corresponds to the "reinforcement production information" related to the construction support system 10 (Figs. 1 to 11) described above. That is, "reinforcement processing information" is a paraphrase of the "reinforcement production information" related to the construction support system 10 (Figs. 1 to 11) in the description of the rebar incorporation support system 60. Therefore, it is also possible to paraphrase "reinforcement processing information" as "reinforcement production information".

[0131] The "construction schedule" determines the construction plan of a building in chronological order. The "multiple construction periods defined step by step in the construction schedule" refers to, in the construction schedule, for example, when it is planned to carry out a certain process (referred to as "Process 1" here) from May 10, 2022 to June 20 of the same year, and carry out another certain process (referred to as "Process 2" here) from June 21 to July 20 of the same year, it refers to May 10, 2022 to June 20, and June 21 to July 20 of the same year.

[0132] Note that the multiple construction periods defined step by step in the construction schedule may partially overlap, for example, like from May 10, 2022 to June 20, and from April 25 to July 10 of the same year. Also, for example, it may be discontinuous, like from May 10, 2022 to June 20, and from July 1 to July 20 of the same year.

[0133] Also, "multiple" may be 3 or more. Furthermore, the "multiple construction periods defined step by step in the construction schedule" may be a specific date. For example, for Process 1, it may be May 10, 2022, or May 20 of the same year in the middle of the period, etc., and for Process 2, it may be June 21, or July 15 of the same year, etc.

[0134] Another aspect of the steel bar supply support system is to create steel bar processing information related to the processing of the steel bars from the steel bar arrangement drawing showing the arrangement of the steel bars used in the construction of the building, A steel bar supply support system that processes the steel bars required in multiple construction periods defined step by step in the construction schedule based on the steel bar processing information and supplies them to the construction site of the building, A data supply unit capable of supplying the steel bar processing information to the outside, A processing unit that processes the steel bars based on the steel bar processing information supplied from the data supply unit, And a construction unit into which the steel bars processed by the processing unit are supplied, The data supply unit Create the three-dimensional model information of the reinforcing bars based on the reinforcing bar drawing information, which is the information of the reinforcing bar drawing. Create the reinforcing bar processing information based on the three-dimensional model information. Store the reinforcing bar processing information. Store a plurality of construction period information indicating the construction periods. Based on the construction period information, supply the reinforcing bar processing information to the processing section according to the construction period. The processing section Perform the processing of the reinforcing bars according to the construction period. The processed reinforcing bars are delivered according to the construction period. It is a reinforcing bar delivery support system.

[0135] "Building", "reinforcing bar drawing", "processing of reinforcing bars", "reinforcing bar processing information", and "a plurality of construction periods defined step by step in the construction schedule" have the same meanings as those in the foregoing aspects. The "data supply section" supplies the reinforcing bar processing information to the outside (such as the processing section). As the data supply section, the data supply section 12 in the example of FIG. 1 can be applied. And examples of the data supply section 12 include information system companies and architectural design offices. In the reinforcing bar delivery support system 60, the construction support device 30 (FIG. 4) of the construction support system 10 can be used as the reinforcing bar delivery support device provided in the data supply section.

[0136] The "supply" of the data may be performed via the same communication network as described for the construction support system 10 (FIGS. 1 to 11), or may be performed via a portable storage medium (such as a USB memory) storing the reinforcing bar processing information.

[0137] The "processing section" processes the reinforcing bars using the reinforcing bar processing information such as the two-dimensional code created by the data supply section. For the processing section, the processing section 16 in the example of FIG. 1 can also be applied. And examples of the processing section include reinforcing bar processors.

[0138] Here, in the construction support system 10 of the example in FIG. 1, the processing unit 16 receives an order from the construction unit 14, performs bending processing on the reinforcing bars, and delivers the fabricated reinforcing bars to the construction unit 14. In contrast, the processing unit 16 in the reinforcing bar supply support system 60 (FIG. 12) performs processing of the reinforcing bars using the reinforcing bar processing information supplied from the data supply unit 12.

[0139] In this case, the data supply unit 12 will have both the functions for the construction support system 10 (FIG. 1) and the functions for the reinforcing bar supply support system 60 (FIG. 12). When the data supply unit 12 functions as the reinforcing bar supply support system 60, it supplies the reinforcing bar processing information related to the reinforcing bar supply support system 60 to a reinforcing bar processor that can function as the processing unit related to the reinforcing bar supply support system 60.

[0140] The "construction unit" can refer to the construction site where the construction of the building (target building) to be built is carried out. Regarding the construction unit, the construction unit 14 in the example of FIG. 1 can be applied. Here, in the construction support system 10 of the example in FIG. 1, the construction unit 14 places an order with the processing unit 16, but in the reinforcing bar supply support system 60 in FIG. 12, the construction unit 14 does not need to place an order with the processing unit 16.

[0141] The delivery of the reinforcing bars to the construction unit 14 may be carried out directly by the processing unit 16 transporting the processed reinforcing bars to the construction unit 14, or the processing unit 16 may place an order with a transporter for the transportation of the processed reinforcing bars and carry it out via the transporter. In the reinforcing bar supply support system 60, the attribute information such as the name of the business operator and the location (address) of the construction unit 14 is provided from the data supply unit 12 to the processing unit 16. Also, in the example of FIG. 12, a delivery unit 18 is provided, and the delivery unit 18 includes a transporter.

[0142] The data supply unit 12 obtains the "reinforcement drawing" and creates reinforcement drawing information, which is information described in and readable from the reinforcement drawing. The reinforcement drawing information is stored in the storage unit 32 of the data supply unit 12. The creation of the reinforcement drawing information can be performed manually by the operator of the construction support device 30 (referring to FIG. 4) or can be automated. The creation of the reinforcement drawing information will be described later.

[0143] Based on the reinforcement drawing information, the data supply unit 12 creates three-dimensional model information of the reinforcing bars. The "three-dimensional model information" of the reinforcing bars can adopt the same information as the three-dimensional model information in the construction support system 10. More specifically, the three-dimensional model information includes various parameters of the reinforcing bars and calculated values calculated using the parameters. Furthermore, examples of the parameters of the reinforcing bars include the number for identifying the reinforcing bars, the bar diameter, the shape, the length of each part, etc. Examples of the calculated values calculated using the parameters include the total length of the reinforcing bars, the length of each part, the weight per bar of the reinforcing bars, etc.

[0144] In addition, the three-dimensional model information can include the number of bars used, the total weight (bar weight) of the required number of bars, etc. Furthermore, the number of bars and the total weight (bar weight) of the required number of bars can be calculated according to each bar number, each shape, and each bar diameter, etc.

[0145] Also, the information on the length of each part in the three-dimensional model information includes information on the radius of the bent part and the length of the bent part of the reinforcing bar. Furthermore, the information on the length of each part also includes center dimension information and outer surface dimension information. The three-dimensional model information is also used to create reinforcing bar processing information. The reinforcing bar processing information is created based on the information included in the three-dimensional model information.

[0146] The data supply unit 12 stores the steel bar processing information and the construction time information. For storing the steel bar processing information and the construction time information, the storage unit 32 of the construction support device 30 (Fig. 4) can be used, but it is also possible to use other storage devices (not shown). The "construction time information" is the information indicating the construction time described above.

[0147] The steel bar processing information is supplied from the data supply unit 12 to the processing unit 16 according to the construction time. "Based on the construction time information, the steel bar processing information is supplied to the processing unit according to the construction time," means that the data supply unit 12 supplies the steel bar processing information to the processing unit 16 so that the processed steel bars (hereinafter referred to as "processed steel bars") are delivered to the construction unit 14 by the day (which may be a date and time) indicated by the construction time information. The supply of the steel bar processing information from the data supply unit 12 to the processing unit 16 is carried out on the day (which may be a date and time) indicated by the information on the processing order date (processing order date information). The processing order date is the date determined by the processing unit 16 considering the period required to prepare the specified number of steel bars.

[0148] The processing unit 16 processes the steel bars according to the construction time, and the processed steel bars are delivered according to the construction time. From the timing when the data supply unit 12 supplies the steel bar processing information to the processing unit 16 to the timing when the processed steel bars are delivered to the construction unit 14, the period (time) during which the processing unit 16 receives the steel bar processing information, then processes the steel bars, arranges for delivery, and moves the processed steel bars from the processing unit 16 to the construction unit 14 is included.

[0149] In the steel bar delivery support system 60, the data supply unit (here, the data supply unit 12) selects the steel bars required at the construction time indicated by the construction time information, outputs the processing instruction information for the selected steel bars, and outputs the delivery instruction information for the steel bars processed based on the processing instruction information to the construction unit.

[0150] The selection of steel bars by the data supply unit 12 is performed for the steel bars required during each construction period among the steel bars required for the building. The construction period information and the required steel bars are associated as shown in the charts in FIGS. 14(a) and (b), and the steel bar processing information related to the steel bars associated with the construction period information is selected and stored. In the examples of FIGS. 14(a) and (b), the information of "process", "start", and "end" corresponds to the construction period information. "Type of steel bar" and "quantity" correspond to the steel bar processing information. FIGS. 14(a) and (b) will be described later.

[0151] The output of the processing instruction information by the data supply unit 12 is performed toward the processing unit 16 via the communication network. The processing unit 16 receives the processing instruction information from the data supply unit 12 and operates the steel bar processing machine (referring to reference numeral 17 in FIG. 1) based on the processing instruction information. The steel bar processing machine 17 performs bending processing on the straight steel bar before processing to produce steel bars with the desired shape and dimensions.

[0152] The delivery instruction information output from the data supply unit 12 is information indicating that the processed steel bars should be delivered by the construction unit 14 by the day (which may be a date and time) when the processed steel bars are required. The delivery instruction information can be included in the construction period information. For example, the information of the start date of the construction period can also be used as the delivery instruction information. Also, the delivery instruction information can be included in the processing instruction information.

[0153] In the steel bar delivery support system 60, the three-dimensional model information includes the three-dimensional model information of the bent steel bars. As parameters related to the three-dimensional model of the bent steel bars, the center dimension information of the bent steel bars in millimeters and the outer dimension information in a unit larger than millimeters are used. When creating the three-dimensional model information of the bent steel bars, it is possible to create the three-dimensional model information of the bent steel bars including the center dimension information.

[0154] As described above, the information on the length of each part in the three-dimensional model information includes the information on the radius of the bent part of the reinforcing bar and the information on the length of the bent part. Further, the information on the length of each part also includes the center dimension information and the outer dimension information. The center dimension information and the outer dimension information can be the same as those described in the construction support system 10.

[0155] In the reinforcing bar incorporation support system 60, when creating the reinforcing bar processing information, the reinforcing bar processing information is created including the outer dimension information, and the reinforcing bar processing information is converted into a readable code that can be read by a reading device and output.

[0156] The creation of the reinforcing bar processing information is performed by the data supply unit 12. The reinforcing bar processing information corresponds to the "reinforcing bar manufacturing information" in the construction support system 10. The reinforcing bar processing information is converted into a readable code (such as a two-dimensional code) that can be read by a reading device (such as an optical two-dimensional code reader) and output.

[0157] <Information Managed by the Data Supply Unit 12> FIGS. 14(a) and (b) schematically show a list of information managed by the data supply unit 12.

[0162] "Delivery date" indicates the delivery date of the steel bars to Construction Department 14. "Delivery time" indicates the delivery time on the delivery date. In the example of Fig. 14(a), for example, regarding Process 1, it is shown that the delivery of the specified steel bars is carried out at 10:00 on May 10, 2022.

[0163] The "type of steel bar" shown in Fig. 14(b) indicates the type of steel bar incorporated into the construction section 14, and the "quantity" indicates the quantity of steel bars of that type incorporated. In the example of Fig. 14(b), for example, regarding Process 1, it is shown that 200 steel bars of type "A-1", 100 steel bars of type "A-2", and 50 steel bars of type "C-1" are incorporated. The information on the "type of steel bar" corresponds to the symbol for identifying the steel bar object (the "number" symbol in Figs. 5 and 9(a)). Although the illustration is omitted, this information on the "type of steel bar" is linked to the "shape" information in Figs. 5 and 9(b), and the "shape" information can be retrieved from the information on the "type of steel bar".

[0164] The "processor" indicates the steel bar processor that becomes the processing section 16. In the example of Fig. 14(b), the processor is shown abbreviated as "·· Manufacturing Plant". As described above, the "processing order date" is the date determined by the processing section 16 considering the period required to prepare the specified quantity of steel bars. In the example of Fig. 14(b), the processing order date is shown as April 10, 2022.

[0165] "Processed instruction sent" indicates whether the processing instruction for the steel bars required for the corresponding process has been sent.

[0166] The "deliverer" indicates the carrier that is requested to deliver the processed steel bars. In the example of Fig. 14(b), the deliverer is shown abbreviated as "·· Transportation". The deliverer may be the steel bar processor that is the processing section 16. "Delivered" indicates whether the steel bars required for the corresponding process have been delivered to the construction section 14. In the examples of Figs. 14(a) and (b), it is shown that the delivery corresponding to Process 1 has been completed, and the deliveries corresponding to Processes 2 and later have not been made yet.

[0167] The information on "Construction Name" shown in Fig. 14(a) is building identification information for identifying a building. The information on "Construction Location" is construction location identification information for identifying a construction site. The content of the information specified by the "Reinforcement Drawing File Name" is reinforcement drawing information.

[0168] Here, what is shown in Figs. 14(a) and (b) is part of the information managed by the data supply unit 12, and information other than that shown in Figs. 14(a) and (b) is also used for rebar processing and delivery. Also, by appropriately combining the information shown in Figs. 14(a) and (b) and a plurality of pieces of information not shown, it is possible to constitute building identification information, construction location identification information, reinforcement drawing information, 3D model information, construction time information, rebar processing information, delivery instruction information, processing instruction information, and the like.

[0169] <Rebar Delivery Support Method> In the rebar delivery support system 60, the following rebar delivery support method is performed (executed). The rebar delivery support method includes a step of storing a plurality of pieces of construction time information related to the construction schedule of a building, a step of selecting the rebar required at the construction time indicated by the construction time information, a step of outputting the processing instruction information for the selected rebar, and a step of outputting the delivery instruction information for the rebar processed based on the processing instruction information.

[0170] The storage of "construction time information", the output of "processing instruction information", and the output of "delivery instruction information" are the same as those described for the rebar delivery support system 60 so far.

[0171] The flowchart of FIG. 15 more specifically shows the method for assisting in the reinforcement placement in the reinforcement placement assistance system 60. In the method for assisting in the reinforcement placement, a three-dimensional model is created in the data supply unit 12 based on the reinforcement layout drawing (S (step) 1).

[0172] The creation of the three-dimensional model information in the data supply unit 12 can be input into the construction support device 30 by the operator of the construction support device 30 manually via the operation unit 34 (referring to FIG. 4).

[0173] However, it is not limited to this, and it is conceivable to automate the creation of the three-dimensional model information as much as possible. In automating the creation of the three-dimensional model information, the information of the three-dimensional model information, the reinforcement layout drawing (created reinforcement layout drawing), and the reinforcement layout drawing (received reinforcement layout drawing) used in the past are stored in the database 68 shown in FIG. 16, and the relationship between various reinforcement layout drawings and the three-dimensional model information corresponding to these reinforcement layout drawings is used as learning data (teacher data). What is indicated by the symbol CN in FIG. 16 is a communication network such as the Internet. Regarding the database 68, it is possible to connect it to the construction support device 30 via the communication network CN, omit the hardware of the database 68, and store the information of the database 68 in the construction support device 30.

[0174] In creating new three-dimensional model information, the information (new reinforcement layout drawing information) of the provided new reinforcement layout drawing (received reinforcement layout drawing) is input into the construction support device 30. The input of the new reinforcement layout drawing information is performed, for example, by reading the data of the reinforcement layout drawing information provided via a communication network, a USB memory, etc. into the construction support device 30. Also, not limited to these, for example, a paper reinforcement layout drawing may be rasterized using a scanner or the like, and the raster data may be converted into vector data to create reinforcement layout drawing information.

[0175] The data supply unit 12 can determine the degree of approximation with a number of past reinforcement drawing information from the new reinforcement drawing information, and select the past reinforcement drawing information with a relatively high degree of approximation. When selecting the past reinforcement drawing information, it is possible to select the data that approximates with the highest frequency by general statistical information processing (the data with the highest degree of approximation), and use the past 3D model information corresponding to this reinforcement drawing information as the new 3D model information, for example.

[0176] Also, it is possible to select a plurality of the above-mentioned reinforcement drawing information with a high degree of approximation, display the past 3D model information corresponding to this reinforcement drawing information as selection candidates, and let the operator of the construction support device 30 select them.

[0177] And the information processing for automatically determining the 3D model information or displaying the selection candidates as described above can be performed using the function of artificial intelligence (AI).

[0178] Subsequently, as shown in S2 of FIG. 15, based on the 3D model, in the data supply unit 12, a plurality of construction times related to the construction schedule of the building are determined (S2), and construction time information is created. The created construction time information is stored in the storage unit 32 (S3).

[0179] The determination of the construction time in S2 can be determined by consultation between the relevant persons of the data supply unit 12 and the relevant persons of the construction unit 14, but is not limited thereto, and it is also possible to automatically determine using the construction support device 30 or the like.

[0180] The automatic determination of the construction time can be performed, for example, as follows. First, store the construction records of past buildings and structures in the database 68 (FIG. 16). Subsequently, read out the data of the construction record that matches the conditions of the current building (or approximates with the highest frequency by general statistical information processing), fit it to the construction start time, and determine the construction time. Also, it is possible to perform such information processing using the function of artificial intelligence.

[0181] Subsequently, the steel bars required for the construction period indicated by the construction period information are determined (S4), and the processing instruction information for the determined steel bars is output from the data supply unit 12 to the processing unit 16 together with the steel bar processing information (S5). Further, incorporation instruction information for the steel bars processed based on the processing instruction information is output from the data supply unit 12 to the processing unit 16 (S6), and the processed steel bars are incorporated into the construction unit 14 (S7).

[0182] Here, as described above, the incorporation instruction information can be included in the construction period information and / or the processing instruction information. In this case, the output of the processing instruction information will be performed when the construction period information and / or the processing instruction information is output from the data supply unit 12 to the processing unit 16 (S5).

[0183] <Advantages of the Invention Related to the Steel Bar Incorporation Support System 60> According to the steel bar incorporation support system 60 of the present embodiment as described above, it is possible to service the operations from the creation of information required for steel bar processing to the incorporation management of steel bars through information processing technology. Therefore, for example, for a construction site, it is only necessary to perform operations such as providing a reinforcement layout drawing to a service provider via the Internet or the like and requesting the incorporation of steel bars, and it is possible to start or establish a service business in which steel bars are incorporated into the construction site just in time according to the construction period.

[0184] In addition, at the construction site, it is no longer necessary to convey information such as the shape, diameter, and number of steel bars required for construction to the steel bar processing contractor based on the reinforcement layout drawing and the structural design drawing, or to manage the ordering time at the construction site. Therefore, the burden of steel bar arrangement at the construction site can be reduced. And at the construction site, labor saving, effective utilization of human resources, and shortening of the construction period become possible.

[0185] In addition, since the steel bar incorporation support system 60 includes the data supply unit 12, the construction unit 14, and the processing unit 16, the data supply unit 12 can become a service provider.

[0186] In addition, the data supply unit 12 creates three-dimensional model information of the reinforcing bars, creates reinforcing bar processing information based on the three-dimensional model information, and stores the reinforcing bar processing information and the construction time information. The data supply unit 12 supplies the processing unit 16 with the reinforcing bar processing information according to the construction time based on the construction time information. The processing unit 16 processes the reinforcing bars according to the construction time, and the processed reinforcing bars are delivered according to the construction time.

[0187] Therefore, in the data supply unit 12, it is possible to provide services such as obtaining a bar arrangement drawing from the construction site via the Internet, receiving a request for delivery of reinforcing bars, and arranging for the reinforcing bars to be delivered to the construction site according to the construction time. Furthermore, at the construction site, by placing an order for the delivery of reinforcing bars together with the bar arrangement drawing, it is possible to be liberated from many tasks related to the arrangement of reinforcing bars and redirect personnel to other operations.

[0188] The data supply unit 12 selects the reinforcing bars required at the construction time, outputs processing instruction information for the selected reinforcing bars, and outputs incorporation instruction information for the processed reinforcing bars to the construction section. Therefore, according to the reinforcing bar delivery support system 60, it is possible to appropriately arrange the reinforcing bars according to the construction time by using information processing technology.

[0189] In the data supply unit 12, it is possible to create three-dimensional model information of the bent reinforcing bars including the center dimension information of the bent reinforcing bars in millimeters as parameters related to the three-dimensional model of the bent reinforcing bars. Therefore, according to the reinforcing bar delivery support system 60, three-dimensional model information of the bent reinforcing bars with accurate numerical values in millimeters is created. And the data supply unit 12 can provide accurate information regarding the length of the reinforcing bars. Furthermore, it is possible to provide information on the estimated weight and estimated price using the accurate information regarding the length of the reinforcing bars.

[0190] In the steel bar delivery support system 60, when creating the steel bar processing information, the steel bar processing information is created including the outer dimension information, and the steel bar processing information is converted into a readable code that can be read by a reading device and output. Therefore, in the processing unit 16, it is possible to perform processing on the steel bars prepared based on the accurate length information with good workability using the outer dimension information.

[0191] Also, when a change occurs in the construction schedule, the data supply unit 12 processes information such as the construction time information, processing instruction information, and delivery instruction information according to the changed schedule.

[0192] Also, as a situation where the steel bar delivery support system 60 as described above is used, the following situations can be exemplified. The orderer of the steel bars (here, the construction unit 14) uploads the design drawings of the building (structure) (here, the reinforcement layout drawing) to the steel bar delivery support system 60 and requests the contractor (here, the data supply unit 12) to deliver the steel bars, but the design drawings do not include information (processing required information) such as the length of the steel bar before processing, the diameter of the steel bar, and the radius of the bending part, which are necessary for the processing of the steel bars.

[0193] The contractor complements the processing essential information based on the design drawings and creates a 3D model of the steel bars on the system. The orderer views the 3D model on the system, determines the order of ordering the steel bars, the ordering schedule, etc., taking into account the complemented processing essential information, and specifies them on the system. When specifying, a part of the building or a part of the project (such as a part of a column) can be specified.

[0194] The contractor determines the ordering schedule of the steel bars according to the specified order of ordering the steel bars, the ordering schedule, etc., and places an order for processing with the processing unit 16. When placing an order for processing, the steel bar processing information designed in mill units is used to place an order with accurate numerical values. When placing an order for processing, it is possible to order a part of the building or a part of the project (such as a part of a column).

[0195] Here, the order schedule for processing can also be determined by the orderer of the reinforcing bars (here, the construction department 14). In this case, the order receiver (here, the data supply department 12) provides the 3D model to the orderer (here, the construction department 14), and the orderer (here, the construction department 14) determines the step-by-step construction schedule.

[0196] Note that the above-described embodiments are merely examples of implementation in carrying out the invention related to the reinforcing bar delivery support system 60, and the technical scope of the invention should not be construed in a limited manner thereby. That is, the invention related to the reinforcing bar delivery support system 60 can be implemented in various forms without departing from the gist or the main features thereof.

[0197] For example, the reinforcing bar delivery support system 60 can be included in the construction support system 10 and can be a system constituting a part of the construction support system 10.
