Description

[Technical field]

[0001] The present invention relates to an analysis process of a reinforcement drawing for a structure having a reinforced concrete structure. [Background technology]

[0002] In the construction of reinforced concrete (RC) structures, placing the correct number of rebars, at the correct intervals, and of the correct type is one of the most important factors in ensuring the durability and strength of the concrete.

[0003] For this reason, during construction work, design reviews are conducted in which the contractor verifies that there are no errors in the design documents, taking into account the on-site conditions of the work, and rebar arrangement inspections are conducted to check that the correct number of rebars of the type specified in the design drawings are used and are placed at the correct intervals.

[0004] In design verification, to verify that the design documents, which show the diameter, spacing, joint method and joint location, processing shape of the rebars, dimensions, cover thickness, etc., accurately reflect the results of the design calculations, the diameter, spacing, processing shape, etc. of each rebar shown in the design drawings must be checked to confirm the consistency of the drawings.

[0005] In addition, when inspecting rebar arrangement, it is necessary to study the design drawings and determine what type of rebar is arranged, how many, and at what intervals in the area being inspected, picking out each bar one by one from the rebar arrangement drawing, and compiling the results into inspection documents. In the construction of RC structures, the assembling of rebar and pouring of concrete are carried out in stages, so this work must be carried out each time, and the burden cannot be ignored.

[0006] As a method for supporting such reinforcement inspection, for example, a system has been proposed that supports reinforcement inspection by acquiring information on reinforcing bars based on images acquired from a photographing device (for example, Patent Document 1, Patent Document 2, etc.). However, these methods cannot support the efficiency of design verification, and there is a problem in that they do not support preparation for reinforcement inspection by examining design drawings such as reinforcement drawings.

[0007] Meanwhile, in recent years, there has been a push towards CIM (Construction Information Modeling / Management) and BIM (Building Information Modeling), which aim to improve the efficiency and sophistication of construction production systems by introducing 3D models from the research and design stages, and then linking and developing them into 3D models at each stage of construction and maintenance.

[0008] However, unlike architectural construction, where a predetermined pattern of reinforcement is placed in each location, civil engineering work is characterized by the need for on-site adjustments as a one-off order production. In other words, because the shape of the structure varies depending on the design conditions and on-site conditions, each rebar must be placed at an indefinite interval specified in the blueprint. For this reason, civil engineering rebar work is considered to be an area that is extremely difficult to systematize, and manual work is emphasized, with 3D modeling of RC structures not progressing sufficiently.

[0009] Furthermore, even if general contractors and other public works contractors were able to put in a lot of effort to create 3D models such as CIM models, the reality is that the rebar contractors who mainly carry out rebar work are mostly small and medium-sized enterprises, and therefore expensive 3D CAD (computer-aided design), which is a tool for checking and editing 3D models, has not become widespread, and 2D CAD drawings are generally used.

[0010] [Patent Document 1] JP 2020-16088 A [Patent Document 2] JP 2018-173277 A Summary of the Invention [Problem to be solved by the invention]

[0011] The present invention was made in consideration of the above circumstances, and aims to provide technology that enables efficient design review and preparation for reinforcement inspection through information processing based on two-dimensional design drawings. [Means for solving the problem]

[0012] In order to solve the above-mentioned problems, the present invention employs the following configuration. That is, the information processing device according to the present invention comprises: An information processing device that performs analysis processing of a reinforcement diagram related to a structure having a reinforced concrete structure, A data acquisition means for acquiring data including at least the reinforcement drawing; The present invention is characterized in that it has a reinforcement drawing analysis means for processing the reinforcement drawing data acquired from the data acquisition means and analyzing at least information relating to the arrangement of reinforcing bars indicated in the reinforcement drawing.

[0013] The reinforcing bar arrangement drawing referred to here is a drawing showing the arrangement and quantity of reinforcing bars, and refers to a drawing consisting of a plan view, a front view, a side view, a cross section, etc. According to the information processing device configured in this way, it is possible to analyze information related to the arrangement of reinforcing bars written on a two-dimensional reinforcing bar arrangement drawing, and therefore it is possible to efficiently carry out design verification and preparation for reinforcing bar arrangement inspection using the analyzed information.

[0015] The "graphical portion" referred to here includes not only the plan, front, side, and cross-sectional views, but also the arrows in the views, the dimension values ​​indicating the dimensions, and the dimension lines. Also, the "rebar number" is the number given to the type and diameter (and processed shape) of the rebar.

[0020] Here, the "processing drawing" is a drawing showing the processed shape of the reinforcing bar. This allows the shape of the reinforcing bar to be specified based on the processing drawing, making it possible to more accurately analyze the reinforcing bar structure shown in the reinforcing bar arrangement drawing.

[0021] The information processing device may further include a three-dimensional model generation means for generating a three-dimensional model of a reinforcing bar structure represented by the plurality of graphic portions based on information of the plurality of graphic portions extracted by the graphic extraction unit and information of the reinforcing bar shape identified by the reinforcing bar shape identification unit.

[0023] In addition, the data acquired by the data acquisition means includes a rebar mass table, The apparatus may further include a reinforcing bar mass table analysis means for analyzing the reinforcing bar mass table to obtain information on the reinforcing bar mass table. With this configuration, detailed information on the reinforcing bar is obtained from the reinforcing bar mass table, and the detailed information is compared with information on the reinforcing bar obtained from a partial drawing or the like, thereby enabling a more accurate analysis.

[0024] The present invention can also be understood as an information processing system having each of the information processing devices, a display means, and an input means for receiving input from a user. The information processing device may have a housing in which the display means and the input means are integrated.

[0025] The present invention also provides an information processing method for analyzing a reinforcement diagram of a structure having a reinforced concrete structure using an information processing device, comprising: A data acquisition step of acquiring data including the reinforcement drawing; a bar arrangement drawing analysis step of processing the bar arrangement drawing data acquired from the data acquisition means and analyzing at least information related to the arrangement of reinforcing bars written on the bar arrangement drawing; The present invention can also be regarded as an information processing method including the above.

A rebar length calculation step; The method may also include a rebar arrangement spacing calculation step of calculating information relating to the arrangement spacing of the rebars indicated by the spacing between the parallel line segments when there are multiple parallel line segments indicating the rebars in the extracted graphic portion.

[0027] In addition, the figure portion extracted in the figure extraction step includes a reinforcing bar processing diagram, The reinforcing bar diagram analysis step includes: When the processing drawing is extracted in the graphic extraction step, the method may further include a reinforcing bar shape identification step of identifying the shape of the reinforcing bar corresponding to the reinforcing bar number written on the processing drawing as the shape written on the processing drawing and associating it with the reinforcing bar information.

[0028] In addition, the information processing method may further include a 3D model generation step of generating a 3D model of the reinforcing bar structure represented by the plurality of graphic portions based on information of the plurality of graphic portions extracted in the graphic extraction step and information of the reinforcing bar shape identified in the reinforcing bar shape identification step.

[0029] In addition, the data acquired in the data acquisition step may include a reinforcing bar mass table, and the information processing method may further include a reinforcing bar mass table analysis step of analyzing the reinforcing bar mass table to acquire information of the reinforcing bar mass table.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, unless otherwise specified, the dimensions, materials, shapes, relative positions, and the like of the components described in the embodiments are not intended to limit the scope of the present invention.

[0035] <Embodiment 1> (Device configuration) First, the bar arrangement diagram analysis device 1 according to the present embodiment will be described with reference to Fig. 1 to Fig. 7. The bar arrangement diagram analysis device 1 is configured by a general computer. That is, it is a computer having the bar arrangement diagram analysis device 1, a main storage unit such as a read-only memory (ROM) or a random access memory (RAM), and an auxiliary storage unit such as an EPROM, a hard disk drive (HDD), or a removable medium. The bar arrangement diagram analysis device 1 may be configured by a single computer, or may be configured by a plurality of computers linked to each other. Also, some of the functions of the bar arrangement diagram analysis device 1 may be realized by a server (such as a cloud server) on a network.

[0036] Fig. 1 is a block diagram showing an outline of a reinforcement diagram analysis device 1. The reinforcement diagram analysis device 1 analyzes data including a reinforcement diagram of an RC structure expressed in a format such as 2D CAD, and provides the obtained information related to reinforcing bars to a user. Specifically, as shown in Fig. 1, the device includes a control unit 110, input means 120 (e.g., a keyboard, a mouse, a touch panel, a storage medium reading device, etc.), output means 130 including a display means such as a liquid crystal display, storage means 140 (e.g., a hard disk drive, a flash memory, etc.), and communication means 150 (e.g., a LAN interface board, a wireless communication circuit, etc.).

[0037] The control unit 110 is a means for controlling the bar arrangement diagram analysis device 1, and is, for example, a CPU (Cent The processors are processors such as a digital processing unit (DSP) and a digital signal processor (DSP). As functional modules related to the analysis of the reinforcement drawing, the system includes a data acquisition unit 111, a figure extraction unit 112, a reinforcing bar information extraction unit 113, a reinforcing bar line segment association unit 114, a reinforcing bar length calculation unit 115, a reinforcing bar arrangement interval calculation unit 116, and a reinforcing bar inspection support unit 1111, which will be described later.

[0038] Although not shown, the storage means 140 includes a main storage unit such as a read-only memory (ROM) or a random access memory (RAM), and an auxiliary storage unit such as an EPROM, a hard disk drive (HDD), or a removable medium. The auxiliary storage unit stores information for reinforcing bar diagram analysis (e.g., data acquired from reinforcing bar diagrams, data tables such as pre-registered data, various threshold values, etc.), an operating system (OS), various programs, etc. Then, the stored programs are loaded into the working area of ​​the main storage unit and executed, and each component unit, etc. are controlled through the execution of the programs, thereby realizing functional units that fulfill predetermined purposes as described below.

[0039] Next, each functional module included in the control unit 110 will be described. The data acquisition unit 111 acquires data of a two-dimensional bar arrangement drawing such as a CAD drawing related to an RC structure via the input means 120 or the communication means 150. Figures 2 and 3 show an example of the bar arrangement drawing data acquired by the data acquisition unit 111. As shown in Figures 2 and 3, the bar arrangement drawing data includes a bar arrangement cross-sectional drawing D, a processing drawing K, a rebar mass table S, and the like.

[0040] The graphic extraction unit 112 extracts graphic parts drawn on the drawing from the two-dimensional reinforcement drawing data acquired by the data acquisition unit 111. The "graphic parts" referred to here include not only plans, front views, side views, cross-sectional views, but also arrows in the drawing, dimension values ​​indicating dimensions, dimension lines, and the like.

[0041] The extraction of the graphic part may be performed, for example, by setting a mesh-like ruled line (mesh) of an appropriate size for the acquired drawing data, and extracting the area as a graphic part if the area of ​​the mesh where the squares containing graphic elements (lines, text information, etc.) are adjacent to each other is equal to or greater than a predetermined value. FIG. 4 shows an image of the extraction of the graphic part. FIG. 4A shows a state where a mesh is set on the target drawing, and FIG. 4B shows the part extracted as the graphic part by hatching. As shown in FIG. 4B, even if there are two or three adjacent squares containing graphic elements, the area is not extracted as the graphic part.

[0042] In addition, for example, for public works drawings, certain rules are established for the names of layers that make up the drawings, so the names of the layers may be included in the judgment of the extraction of graphic parts. Specifically, for example, layers that do not need to be extracted, such as title blocks, can be excluded from the target range in advance to prevent false detection and improve the accuracy of extraction of graphic parts.

[0043] The reinforcing bar information extraction unit 113 extracts reinforcing bar information including at least the reinforcing bar number from the graphic portion extracted by the graphic extraction unit 112. Note that the "reinforcing bar number" here refers to a number given to the type and diameter (and processing shape) of the reinforcing bar.

[0044] In reinforcement drawings, reinforcing bar numbers are written inside circles (even if there are parts that protrude beyond the circle), so reinforcing bar information, including reinforcing bar numbers, can be extracted by searching for the graphic element of a circle in the drawing. In other words, if there is text information within the graphic element of a circle, the number indicated by that text information is recognized and extracted as the reinforcing bar number. Note that reinforcing bar numbers may be drawn using the same character element or different character elements, depending on the preference of the person drawing them. For example, there are cases where they are drawn as a single character, cases where the characters are split, cases where numbers are written separately above and below, and cases where some characters protrude beyond the circle. For this reason, it is a good idea to treat all characters that overlap a circle as rebar numbers and to read the rebar number from their relative positions.

[0045] In addition, since the number, diameter, and length of the reinforcing bars may be written adjacent to the reinforcing bar number, in this case the reinforcing bar information extraction unit 113 extracts the information from the graphic portion and links it to the reinforcing bar number. Specifically, it searches for characters adjacent to the graphic representing the reinforcing bar number, extracts information on the character string in the vertical direction of the rotation angle of the reinforcing bar number (characters), analyzes the pattern of the extracted characters, and links the written information of the number, diameter, and length to the reinforcing bar number.

[0046] The reinforcing bar line associating unit 114 extracts line segments indicating reinforcing bars specified by the reinforcing bar information extracted by the reinforcing bar information extracting unit 113 from the graphic portion, and associates the line segments with the reinforcing bar information. Specifically, for example, a line segment adjacent to the graphic representing the reinforcing bar number is searched for, and if an arrow-shaped element overlapping the line segment is present, the line segment tangent to the apex of the arrow is determined to be a reinforcing bar specified by the reinforcing bar information (reinforcing bar number), extracted, and associated with the reinforcing bar information. Note that the arrow referred to here has various shapes, and includes an arrow represented by a single diagonal line segment.

[0047] The reinforcing bar length calculation unit 115 calculates the length of the reinforcing bar shown in the diagram portion based on the data of the reinforcing bar arrangement drawing. Specifically, if a dimension value indicating the dimension of the line segment indicating the reinforcing bar is described, the length of the reinforcing bar may be calculated based on the dimension value. Even if a dimension value directly indicating the length of the line segment is not described, the length of the target reinforcing bar may be calculated using the dimension value of other structures (including reinforcing bars).

[0048] When there are multiple parallel line segments representing rebars in the graphic part, the rebar spacing calculation unit 116 calculates information on the spacing of rebars indicated by the spacing between the parallel line segments. Specifically, for example, the unit searches for dimension lines on the extensions of the parallel line segments in the graphic part, and when a dimension line is detected, it extracts the dimension value written on the dimension line, and calculates information on the spacing of rebars based on the extracted dimension value. Note that when the dimension value differs from the value obtained from the layout in the drawing, the dimension value may be taken as positive to correct the layout of rebars.

[0049] The bar arrangement inspection support unit 1111 displays information related to the reinforcing bars within a range designated by the user of the bar arrangement drawing, based on the analyzed bar arrangement drawing data.

[0050] (Processing flow) Next, an example of a method of using the bar arrangement diagram analysis device 1 will be described. By using the bar arrangement diagram analysis device 1 as described above, it is possible to efficiently perform preparation work for a bar arrangement inspection. Fig. 5 is a flowchart showing a process flow for acquiring information for preparing for a bar arrangement inspection using the bar arrangement diagram analysis device 1. The bar arrangement diagram analysis device 1 executes the following processes when triggered by, for example, an instruction to start an analysis process by a user via the input means 120.

[0051] In the bar arrangement diagram analysis device 1, first, the data acquisition unit 111 acquires bar arrangement diagram data for an RC structure via the input means 120, the storage means 140, the communication means 150, etc. (S101). Next, the graphic extraction unit 112 extracts one or more graphic parts from the data acquired in step S101 (S102). Furthermore, the reinforcing bar information extraction unit 113 extracts reinforcing bar information including at least reinforcing bar numbers from the graphic parts extracted in step S102 (S103). Next, the reinforcing bar line segment association unit 114 extracts line segments indicating reinforcing bars specified by the reinforcing bar information extracted in step S103 from the graphic parts, and performs a process of associating the line segments with the reinforcing bar information (S104). Next, the reinforcing bar length calculation unit 115 calculates the length of the reinforcing bar shown in the graphic parts based on the data acquired in step S101 (S105). 105). Furthermore, the rebar spacing calculation unit 116 calculates information on the spacing of the rebars, which is indicated by the spacing between the parallel line segments of the figure (S106). The data extracted and calculated in each of these steps is stored in the storage means 140 as needed.

[0052] The reinforcement drawing analysis device 1 then receives an instruction to select an inspection range from the user (S107). The user performs an operation to select an inspection range via the input means 120. Fig. 6 shows an example of a screen display in a state where the user has performed an operation to select an inspection range for the reinforcement drawing displayed on the display screen. The white rectangular portion in Fig. 6 is the range selected by the user.

[0053] When the selection operation from the user is accepted in step S107, the reinforcement diagram analysis device 1 performs processing to display information on the reinforcing bars (including the arrangement interval) included within the selected range on the screen, based on the information obtained in steps S102 to S106, through the reinforcement bar inspection support unit 1111. Fig. 7 shows an example of a screen in which reinforcing bar information for the specified range has been output. The user can use the output results as inspection information by outputting them to an inspection book or the like, copying them to the clipboard, outputting them to another system that manages the inspection book, or the like.

[0054] According to the above-configured bar arrangement diagram analysis device 1, it becomes possible to efficiently perform preparation work for a bar arrangement inspection by information processing based on design drawings written in two dimensions. In this embodiment, the control unit 110 is configured to serve both as a data acquisition means and a bar arrangement diagram analysis means.

[0055] <Embodiment 2> (Device configuration) Next, a bar arrangement drawing analysis device 2 according to a second embodiment of the present invention will be described with reference to Fig. 8 to Fig. 18. Fig. 8 is a block diagram showing an outline of the bar arrangement drawing analysis device 2 according to this embodiment. Note that the bar arrangement drawing analysis device 2 according to this embodiment is obtained by adding many functions to the bar arrangement drawing analysis device 1 according to the first embodiment, so that the same reference numerals are used to indicate the same configurations and processes as those according to the first embodiment, and detailed descriptions thereof will be omitted.

[0056] As shown in FIG. 8, the reinforcement drawing analysis device 2 differs from the reinforcement drawing analysis device 1 in that it includes the functional modules of a rebar shape identification unit 117, a rebar mass table analysis unit 118, a 3D model generation unit 119, a design review support unit 1112, and a 3D model synthesis unit 1113, but is similar to the reinforcement drawing analysis device 1 in other respects.

[0057] When the graphic extraction unit 112 extracts a processing drawing, the reinforcing bar shape specification unit 117 specifies the shape of the reinforcing bar related to the reinforcing bar number written on the processing drawing as the shape written on the processing drawing, associates it with the reinforcing bar information, and stores it as a data table in the storage means 140. Fig. 9 shows an example of a data table stored as a processing drawing table, and Fig. 10 shows an example of a data table stored as a processing drawing reinforcing bar information table.

[0058] The reinforcing bar mass table analysis unit 118 searches for and analyzes the reinforcing bar mass table from the data acquired by the data acquisition unit 111, and acquires information on the reinforcing bar mass table. Specifically, for example, a graphic element with a rectangular outline is detected from the reinforcement drawing, and an element containing the title characters of the reinforcing bar mass table, such as the symbol, diameter, length, and number, within the rectangle is extracted as the reinforcing bar mass table, and stored as a data table in the storage means 140. Fig. 11 shows an example of a data table stored as the reinforcing bar mass table table.

[0059] The 3D model generating unit 119 generates a 3D model for each part based on the information of the multiple reinforcement cross-sectional views (graphical parts) extracted by the graphic extracting unit 112 and the information of the reinforcement bar shape specified by the reinforcement bar shape specifying unit 117. A 3D model is generated by specifying the direction, calculating the 3D arrangement coordinates of the rebars shown in the reinforcement cross-sectional diagram, and applying the processing shape of each rebar. The detailed method of generating the 3D model will be explained later.

[0060] The design review support unit 1112 compares the rebar mass table information acquired by the rebar mass table analysis unit 118 with the processing drawing information acquired by the rebar shape specification unit 117 or the rebar information obtained from the 3D model generated by the 3D model generation unit 119, and outputs the comparison result to the display device. The user can refer to the comparison result to perform design review.

[0061] The 3D model synthesis unit 1113 provides a user interface for synthesizing 3D models of multiple parts of an RC structure, and synthesizes the 3D models of multiple parts in accordance with user instructions to generate a 3D model of a single RC structure.

[0062] (Analysis processing for design review support) Next, a case where a process for design review support is performed using the bar arrangement drawing analysis device 2 having the above-mentioned configuration will be described. Fig. 12 is a flowchart showing the flow of the process for design review support. As shown in Fig. 12, the processes from step S101 to step S106 are the same as those in the first embodiment, and therefore the description will be omitted.

[0063] The reinforcing bar shape identifying unit 117 of the reinforcing bar arrangement drawing analysis device 2 identifies the shape of the reinforcing bar related to the reinforcing bar number written on the processing drawing as the shape written on the processing drawing, associates it with the reinforcing bar information, and stores it as a data table in the storage means 140 (S201). Next, the reinforcing bar mass table analyzing unit 118 searches for and analyzes the reinforcing bar mass table from the reinforcing bar arrangement drawing, obtains information on the reinforcing bar mass table, and stores it as a data table in the storage means 140 (S202).

[0064] Next, the reinforcement diagram analysis device 2 generates a 3D model of the portion shown by the multiple reinforcement cross-sectional views by the 3D model generation unit 119 (S203), and stores the 3D model in the storage means 140 (S204). Here, a specific example of the 3D model generation will be described.

[0065] First, the 3D model generating unit 119 identifies a view showing a predetermined face (for example, the front) from among multiple reinforcement cross-sectional views showing one part. The identification method may be to accept an instruction from a user, or may be performed automatically according to a predetermined rule. Next, the reinforcing bar number shown in the identified reinforcement cross-sectional view is acquired, and the length of the reinforcing bar calculated by the reinforcing bar length calculating unit 115 is obtained. Then, a reinforcing bar cross-sectional view of another face showing the same part, which has the same reinforcing bar number as the reinforcing bar number shown in the previously identified drawing, is searched for, and the length of the reinforcing bar in the relevant figure part to which the same reinforcing bar number is assigned is obtained. Then, the reinforcing bar lengths of both are compared, and if they are the same length, it is determined that the reinforcement cross-sectional view showing the previously identified face and the reinforcement cross-sectional view searched later are views of faces that are in contact in a perpendicular direction, and are arranged on the 3D coordinate system.

[0066] In this way, the directions of all rebar cross-sectional views are determined, and the three-dimensional coordinates of each rebar are obtained. Here, only rebars that can be identified as the same rebar from the rebar arrangement information obtained from multiple cross sections are given three-dimensional arrangement coordinate information and recognized as rebars. Figure 13 shows the relationship between three rebars arranged in three dimensions and the front (cross-sectional) view, plan (cross-sectional) view, and side (cross-sectional) view. As shown in the example in Figure 13, it is confirmed whether the X coordinate of the front view rebar matches the X coordinate of the plan view rebar, whether the Z coordinate of the front view rebar matches the Z coordinate of the side view rebar, and whether the Y direction length of the plan view rebar matches the Y direction length of the side view rebar.

[0067] Furthermore, a process is performed to apply the shape described in the processing drawing to the rebars arranged on the 3D coordinate system. When rebar information is obtained from a cross-sectional drawing, it may be impossible to determine whether the shape is that of multiple rebars in contact with each other or the shape of a single rebar. By applying the processing shapes of the rebar linked by numbers, it becomes possible to distinguish these differences.

[0068] In addition, a CIM model may be further generated by adding component information (such as names, shapes, dimensions, physical properties and physical property values, quantities, and other information that can be added to the components; hereinafter referred to as attribute information) to the 3D model generated here.

[0069] Returning to the explanation of the process for supporting design verification, after the 3D model is saved in step S204, the reinforcement drawing analysis device 2 waits for an instruction for verification analysis from the user. After that, when an instruction is received from the user (S205), the design verification support unit 1112 performs an analysis according to the instruction and displays the result on the screen (S206).

[0070] There are two ways to perform analysis for verification: comparing the information in the rebar mass table with the rebar information obtained from the processing drawing information, and comparing the information in the rebar mass table with the rebar information extracted from the CIM model. Figure 14 shows examples of the analysis results display screens for these two methods. Figure 14A shows a comparison with the information obtained from the processing information, and Figure 14B shows a comparison with the rebar information extracted from the CIM model. The displayed results screens can also be printed out, and users can use these output results to perform verification.

[0071] (3D model synthesis) Next, a process of synthesizing the generated 3D models using the reinforcement drawing analysis device 2 will be described. Fig. 15 is a flowchart showing the flow of the process for synthesizing the 3D models. As shown in Fig. 15, the processes from step S101 to step S204 are the same as those described above, and therefore the description will be omitted.

[0072] When the 3D models of multiple parts are stored in the storage means 140, the reinforcement drawing analysis device 2 (3D model synthesis unit 1113) outputs an interface (I / F) that displays the stored 3D model for each part on a screen in accordance with a user's operation (S301). FIG. 16 shows an example of the I / F screen. As shown in FIG. 16, a list of the generated CIM models for each part and a detailed display of the CIM model of the selected part are displayed. When the user selects two CIM models to be synthesized and presses a button to instruct synthesis, the 3D model synthesis unit 1113 accepts the synthesis instruction (S302) and generates a synthesized 3D model (S303).

[0073] According to the above-described bar arrangement diagram analysis device 2, it becomes possible to efficiently carry out design verification work by information processing based on design drawings written in two dimensions. Also, a three-dimensional model of the target structure can be generated from the two-dimensional design drawings, and the user can utilize this at each stage of investigation, design, construction, and maintenance and management. In this embodiment, the control unit 110 is configured to serve as a data acquisition means, a bar arrangement diagram analysis means, a rebar mass table analysis means, and a three-dimensional model analysis means.

[0074] (Modification) In addition, in the above-mentioned bar arrangement drawing analysis device 2, when various information is extracted from the bar arrangement drawing, the user may be able to confirm and edit the information. Specifically, for example, when the reinforcing bar mass table analysis unit 118 searches for the reinforcing bar mass table from the bar arrangement drawing and extracts the information, a confirmation screen may be displayed so that the user can confirm and correct whether the position of the graphic part determined to be the reinforcing bar mass table is correct (including insufficient or excessive area). Also, a screen may be displayed that displays the acquired (text) information of the reinforcing bar mass table in an editable form. FIG. 17 shows an example of such an editing screen for reinforcing bar mass table information.

[0075] In addition, as shown in Figure 6, the cross section of two layers is sometimes divided into half and expressed as one cross section, but in the case of a cross section in which two such cross sections are combined into one, A function for generating a 3D model from a plan view may be provided. Specifically, such a reinforcement cross-sectional view of two half-surface layers can be divided and inverted and copied, and replaced with two full-surface cross-sectional views of one layer. Fig. 18 shows an example of a screen displayed when dividing and inverting a reinforcement cross-sectional view. Fig. 18A shows an example of a screen for setting the position and direction for dividing the reinforcement cross-sectional view, and Fig. 18B shows an example of a screen showing the results of dividing and inverting the cross-sectional view. By carrying out such processing, it becomes possible to generate a 3D model even from a reinforcement cross-sectional view in which two sections are combined into one.

[0076] <Embodiment 3> Next, a third embodiment of the present invention will be described with reference to Fig. 19. Fig. 19 is a block diagram showing the overall configuration of a bar arrangement drawing analysis system 3 according to this embodiment. The bar arrangement drawing analysis system 3 is configured such that a center server 20 and an information processing terminal 30 are connected via a communication network N. Note that the communication network N may be, for example, a WAN (Wide Area Network), which is a global public communication network such as the Internet, or other communication networks. The communication network N may also include a telephone communication network such as a mobile phone, or a wireless communication network such as Wi-Fi (registered trademark).

[0077] The center server 20 is configured by a general server computer, and includes a control unit 210 , a storage unit 240 , and a communication unit 250 .

[0078] The control unit 210 is a means for controlling the center server 20, and is configured by, for example, a CPU. The control unit 210 also includes the following functional units: a data acquisition unit 211, a graphic extraction unit 212, a reinforcing bar information extraction unit 213, a reinforcing bar line segment association unit 214, a reinforcing bar length calculation unit 215, a reinforcing bar arrangement interval calculation unit 216, and a reinforcing bar inspection support unit 2111.

[0079] The storage means 240 is configured by an EPROM, HDD, etc., as described above, and stores an operating system (OS), various programs, various tables, and various other data acquired via the communication network N.

[0080] The communication means 250 is a communication means for connecting the center server 20 to the communication network N, and is configured to include, for example, a LAN interface board and a wireless communication circuit for wireless communication.

[0081] The information processing terminal 30 is configured as a general computer, and includes an input means 301, a communication means 302, and an output means 303. The information processing terminal 30 may be either a stationary terminal or a portable terminal.

[0082] The input means 301 is a means for accepting information input from the outside, such as a keyboard, a mouse, a touch panel, a camera, a microphone, etc. The communication means 302 includes, for example, a LAN interface board and a wireless communication circuit for wireless communication. The output means 303 includes, for example, a liquid crystal display, a speaker, etc.

[0083] In the reinforcement drawing analysis system 3 of this embodiment, the functional units of the data acquisition unit 211, the figure extraction unit 212, the reinforcing bar information extraction unit 213, the reinforcing bar line association unit 214, the reinforcing bar length calculation unit 215, the reinforcing bar arrangement spacing calculation unit 216, and the reinforcing bar inspection support unit 2111 are generally similar to the functional units of the reinforcement drawing analysis device 1 of embodiment 1, but differ in that input such as acquisition of reinforcement drawing data and output such as output of analysis results are performed via a communication network N.

[0084] Specifically, for example, the user inputs the following via the input means 301 of the information processing terminal 30: The data of the bar arrangement drawing is transmitted to the center server 20 via the communication network N, and the data acquiring unit 211 acquires the bar arrangement drawing data. That is, the bar arrangement drawing analysis system 3 according to this embodiment is a partial cloud-based version of the bar arrangement drawing analysis device 1 according to the first embodiment.

[0085] When outputting reinforcing bar information for reinforcement bar inspection using the reinforcement bar arrangement drawing analysis system 3 according to this embodiment, the user uses the information processing terminal 30 to transmit data to the center server 20 and input instructions.

[0086] In this way, the reinforcement bar inspection support unit 2111, which has received instructions from the user, transmits information about the rebars (including their placement spacing) contained within the selected range to the information processing terminal 30 via the communication means 250 and the communication network N, and the user checks the rebar information using the output means 303 of the information processing terminal 30.

[0087] With a reinforcement drawing analysis system 3 having such a configuration, the system operator can set up a central server 20, allowing individual users to enjoy the results of the analysis processing of the desired reinforcement drawing without having to prepare a dedicated terminal (program).

[0088] <Other> The above description of each example is merely illustrative of the present invention, and the present invention is not limited to the specific embodiments described above. Various modifications and combinations of the present invention are possible within the scope of the technical concept thereof.

[0089] For example, a part or all of the functional units of the bar arrangement drawing analysis device 2 according to the second embodiment may be cloud-based like the bar arrangement drawing analysis system 3 according to the third embodiment. Moreover, the acquired bar arrangement drawing data is not necessarily limited to CAD drawings, as long as it is in a data format that allows distinguishing between graphic parts and text parts and reading them.
