Description

[Technical Field]

[0001] The present invention relates to a material counting system suitable for counting materials used in a building. [Background technology]

[0002] Conventionally, there is known prior art for a system that calculates the quantity of building materials from the BIM information of a building (see, for example, Patent Document 1). This system acquires the shape of each part of the building model, the dimensions of the building materials used in each part, and construction information from a storage unit, and executes a process to calculate the quantity of building materials used in each part of the building model from this information.

[0003] According to the prior art system, the shape of the columns and walls of the structure, the dimensions of the building materials, and their construction information can all be included in the information of the building model, so it is thought that the quantity of building materials to be ordered can be automatically calculated from this. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-119240 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the above-mentioned prior art system requires complex calculations, such as first obtaining shape information such as the area of ​​each part and the length of each side (distance between walls) from the building model, then obtaining dimensional information such as the thickness, width, and length of the interior materials used in each part, and then obtaining the construction standards that must be observed when installing the interior materials in each part, and then calculating the quantity of base materials using the shape information and dimensional information, or calculating the quantity of base materials taking into account the work procedure that satisfies the construction standards when allocating the base materials.As a result, there is the problem that it takes a long time to complete the calculations, which increases the load.

[0006] Furthermore, prior art systems require a huge amount of information for their calculations. Therefore, when creating a BIM model, detailed information about materials, interior finishes, and other aspects of each structural object must be entered one by one. Furthermore, because the information entered in this way is embedded in each object as text data, it cannot be easily viewed on the BIM model. Therefore, to know the specifications of the finishing materials, it is necessary to open and check the embedded information for each object one by one.

[0007] Therefore, the present invention provides a system that is more convenient. [Means for solving the problem]

[0008] The present invention provides a material counting system. Note that the following parenthesized text is for reference purposes only and does not limit the present invention in any way.

[0009] The material accounting system of the present invention includes a setting unit and a counting unit. The setting unit sets information about materials used for the interior and exterior of a building as color information for the interior and exterior objects in a BIM model. When creating a BIM model of a building, information about the materials used for the interior and exterior (material information) is set as color information for the objects. Color information can be assigned a unique value for each type of material used, allowing any type of material (product name, part number, etc.) to be represented by color information. Transparency may also be set in the color information. The color information may also include location information for the objects, such as walls, floors, and ceilings. The counting unit extracts color information from the BIM model using a general-purpose program such as a BIM tool, and counts the number of objects for which color information is set in the form of a list of surface areas (which may include location information) of the objects for which color information is set, as well as a total area.

[0010] As a result, the counted quantity of objects directly represents the quantity of materials (such as interior and exterior finishing materials) used that correspond to the color information, making it easy to count the quantity of materials required. Furthermore, because the quantity of objects can be calculated simply from color information, there is no need for particularly complex calculations, and object quantities can be calculated quickly. By linking material information to color information in this way, it becomes possible to calculate the number of objects by material type (position coordinates) based on the surface area (the part that is visible to the human eye) of the objects used, without compromising the display of the BIM model.

[0011] Furthermore, during the BIM model creation stage, designers only need to set color information for objects, eliminating the need to set finishing material information as embedded information for each object. For example, there is no need to enter text data such as "wallpaper #xx, paint #xx, tile #xx, flooring #xx" into each object's material information. Furthermore, because the color information set for objects in a BIM model is visible (recognizable visually) when the BIM model is displayed on screen, it is easy to check the object's material information (the materials used for the interior and exterior) on screen.

[0012] Furthermore, the material calculation system can generate an intermediate file from the results of calculating the quantity of objects with color information set from the BIM model. This intermediate file can output the calculated quantity of objects in a format (such as a list) that associates the color information with the calculated object quantity.

[0013] The material calculation system is equipped with a calculation means. The calculation means calculates the amount of material required to finish the interior and exterior of a building using the color information in the intermediate file. The color information can include the type of material used (product name, model number, etc.) and the location where it is used (walls, floors, ceilings, stairs, roofs, etc.), so the amount of material used (cumulative amount) can be quickly and easily calculated in a list format for each material type and location where it is used (location information).

[0014] Preferably, the material counting system can have a finishing material database that registers information on materials corresponding to color information. This allows the color information in the intermediate file to be used to search for material information in the finishing material database, thereby calculating the amount of material needed to finish interior and exterior items based on the counted number of objects. Furthermore, the system can calculate the cumulative amount for each material (finishing material) product number and usage location (by area for wallpaper, tiles, flooring, etc., or by square meter for paint and other coatings), and generate a list of locations where finishing materials are used. Note that the cumulative amount can be adjusted to account for material loss per area (such as irregular shapes, scraps, and mistakes) as a correction parameter.

[0015] The material counting system of the present invention can output the calculation results as data. That is, based on the calculation results of the object quantity, the amount of materials (finishing materials) required for finishing the interior and exterior of the building is output in a file format associated with color information. In this case, since the color information also includes information such as the type of material and the location of use, as described above, it is possible to output a file listing the amount of material used by type and by location of use. This output file will show the cumulative amount of material required for finishing the interior and exterior of the building.

[0016] So far, the material accounting system of the present invention has shown a processing flow that functions effectively from the input stage to the output stage, such as setting the color information of objects corresponding to materials when creating a BIM model of a building, calculating the quantity of objects, and outputting a file of the amount of material used.In addition, the material accounting system of the present invention can also function reversibly from the output stage to the input stage.

[0017] In other words, when material information is changed in the output file, the material accounting system can update the color information of the set object in the BIM model to the color information corresponding to the changed material information. For example, if the type of material for a certain usage location is changed in the output file, the setting of the object for that usage location in the BIM model is updated to the color information representing the changed material type. Therefore, if changes are made to material information in the output file, the operation is reversibly fed back to the BIM model, eliminating the need to go back to the input stage and modify the BIM model.

[0018] The material counting system of the present invention may have the following configuration. (1) When displaying an image of a BIM model, a display adjustment means is provided that can adjust the display color of the BIM model based on the color information of the set object. (2) The setting means can set color information and transparency as parameters used when displaying a BIM model as an image. (3) The display adjustment means can adjust the display color of the BIM model according to the set color information and transparency.

[0019] The configuration (1) above makes it possible to easily recognize interior and exterior material information by the display color of the object when displaying an image of a BIM model. According to the above (2) and (3) configurations, color information is easily visible on the BIM model, but if the color information is a primary color system, the image contrast may become too high and visibility may be hindered. For this reason, by setting the transparency according to the color information and adjusting the display color of the BIM model, it is possible to realize an image display that does not hinder visibility.

[0020] (4) The display adjustment means may be capable of switching between a texture display of an object representing the interior and exterior appearance of a building and a color display based on the color information of the object set by the setting means when displaying an image of a BIM model.

[0021] According to the configuration (4) above, the BIM model can be displayed as a texture to allow the exterior (interior) of the building to be checked in an image, and the finishing materials of the object can be displayed as a color to represent the material, thereby further improving convenience. [Effects of the Invention]

[0022] As described above, according to the present invention, a system with improved convenience can be provided. [Brief explanation of the drawings]

[0024] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The following describes an embodiment of the present invention with reference to the drawings. In the following embodiment, a preferred example of a material counting system is given, but the present invention is not limited to the illustrated embodiment.

[0025] [System configuration example] 1 is a block diagram showing an example of the configuration of a material calculation system 100. The material calculation system 100 is configured, for example, with a design computer. Note that the design computer may be a general-purpose computer device, and may be in any form, such as a desktop, laptop, or tablet.

[0026] The design computer has installed thereon, for example, a BIM tool 110 and a cost estimation program 120. The BIM tool 110 can be configured using a general-purpose program (for example, Revit: registered trademark). The cost estimation program 120 is a dedicated application prepared to configure the material calculation system 100 together with the BIM tool 110.

[0027] The design computer has, as peripheral devices, a display unit 130 and an input unit 140. The display unit 130 is, for example, a display device, and the input unit 140 is, for example, an input device such as a keyboard, a mouse, or a tablet.

[0028] The BIM tool 110 of the design computer may have, for example, a calculation processing unit 112, a display processing unit 114, an object management unit 116, a memory unit 118, etc. Of these, the calculation processing unit 112 is a functional element customized and optimized for the material calculation system 100, and in addition to calculating BIM model objects based on color information, it can also function as an API when calling the cost estimation program 120. The display processing unit 114 executes display control processing when displaying a BIM model, etc. on the display unit 130. The object management unit 116 manages property information, such as position information, shape information, and material information, of objects on the BIM model. The memory unit 118 manages access to the hardware memory area of ​​the design computer.

[0029] In the design computer, the tallying unit 112 on the BIM tool 110 side tallies the quantity of objects from the color information of the BIM model, and generates the results as an intermediate file MF. The tallying unit 112 calls the estimation program 120 and passes the generated intermediate file MF to the estimation program 120.

[0030] [Example of intermediate file] The intermediate file MF includes, for example, the following information: (1) Color information set for each object on the BIM model For "color information," for example, RGB color numbers, CMYK color numbers, LAB color numbers, etc. can be used as appropriate. Color numbers can be unique values ​​(color numbers #xxxx, etc.) that differ for each type of material, so the color number set for an object directly represents the type of material (product name, part number). For this reason, designers only need to set (assign) color numbers to each object on the BIM tool 110, and there is no need to embed detailed information about the material in text data, etc., for each object. The color information may also be set together with transparency. Transparency is useful for adjusting contrast and improving visibility when displaying the BIM model as an image on the display unit 130. Furthermore, the color information may include information about the location where the material is used (walls, floors, ceilings, stairs, roofs, coordinates, etc.) When including location information, there are two patterns: (i) setting different color information (color numbers) for each location where the material is used, and (ii) linking location information to color information (color numbers) with a suffix or the like.

[0031] (2) Total quantity (object quantity) list The "cumulative amount" at the intermediate file MF stage is merely the quantity of objects with color information set (surface area, total area, etc.), not the final amount of material used. The quantity of objects is tallied by color number, and if the color information includes location information, the quantity of objects is tallied by location. This "cumulative amount" is listed by the location of the object. For example, "Coordinates / Area name Wall...cumulative amount xxx (m 2 )," "Coordinates / Area name Floor... Total volume xxx (m 2 )," "Coordinates / Area name Ceiling... Accumulated amount xxx (m 2 )," "Coordinates / Area name Stairs... Total amount xxx (m 2 The aggregated results are listed, such as "

[0032] Furthermore, if multiple color numbers (#xxxx,...) are set, such intermediate files MF are generated for each color number.

[0033] The cost estimation program 120 may have, for example, a search processing unit 122, a finishing material database 124, and an estimation file management unit 126. When the cost estimation program 120 is called by the aggregation processing unit 112 on the BIM tool 110 side, the search processing unit 122 searches for material information from the finishing material database 124 based on the intermediate file MF, and calculates the estimated amount of the finishing material (area in the case of wallpaper, tiles, flooring, etc., and m in the case of coating materials such as paint). 2 The search processing unit 122 calculates the total amount (quantity of the material converted). The finishing material database 124 stores information on the finishing materials corresponding to the color information (for example, the product name, product number, unit price, etc. of the finishing material). The search processing unit 122 may set the loss per area (irregular shape, scraps, mistakes, etc.) for each material as a correction parameter. The search processing unit 122 then generates (outputs) a list of the calculated total amounts as an accumulation result file RF.

[0034] [Example of an accumulation file] The integration result file RF includes, for example, the following information: (1) Color information (color number) The color information specified in the intermediate file MF is also carried over to the integration result file RF. (2) Finishing material (product name and number) Information on the material (finishing material name, product number, unit price, manufacturer, etc.) retrieved from the finishing material database 124 is output to the calculation result file RF. (3) List of accumulated quantities The calculation results of the amount used (total area, total weight, etc.) for each type of finishing material are output to the calculation results file RF. The calculation results are also listed by interior and exterior location. For example, "Coordinates / Area name Wall...Calculated amount xxx (m 2 )," "Coordinates / Area name Floor... Total volume xxx (m 2 )," "Coordinates / Area name Ceiling... Accumulated amount xxx (m 2 )," "Coordinates / Area name Stairs... Total amount xxx (m 2 The total amount may be expressed as a total number (xxx sets), total weight (xxx kg), total length (xxx m), or the like, or may be expressed as a purchase price.

[0035] The integration file management unit 126 executes data file control such as saving, external output, and updating of the generated integration result file RF. If the design computer is connected to a network such as a LAN, the integration result file RF can be printed on a printer on the network or shared with other computers. The integration result file RF can also be displayed on the display unit 130 of the design computer.

[0036] The above is an outline of an example of the configuration and functions of the material counting system 100. Next, examples of various processes executed by the material counting system 100 will be described.

[0037] [Color information setting process] 2 is a flowchart showing an example of the procedure for color information setting processing executed on the BIM tool 110 side. In this process, when designing a building (architecture, civil engineering, etc.) using BIM (CAD), when combining objects to create a BIM (3D) model of the building, information on the finishing materials (interior and exterior) can be easily set by setting material information of the objects to be used as color information. The procedure will be explained below along with an example procedure.

[0038] Step S100: A target object is specified on a BIM model in the BIM tool 110. For example, if the BIM model is an apartment building, targets such as an exterior wall object and an interior wall object are specified.

[0039] Step S102: Specify the information on the materials to be used for the interior or exterior finish of the specified target object by linking it to color information. Note that color information corresponding to the finishing materials is presented to the designer in advance on the BIM tool 110 in the form of a list data or the like. Therefore, when specifying the materials to be used for the interior and exterior finish on the BIM model, the designer only needs to set the color information for the target object. Alternatively, color information can be copied and pasted from another object for which color information has already been set.

[0040] Step S104: Determine whether to include object location information in the color information. This determination can be made based on the initial settings of the BIM tool 110, for example. If the initial setting is "include object location information in color information" (Yes), then step S106 is executed. On the other hand, if the initial setting is "do not include object location information in color information (set separately)" (No), then step S108 is executed.

[0041] [When location information is included in color information] Step S106: Set color information for the target object, including location information (walls, floors, ceilings, stairs, coordinates, etc.). As a result, color information (color number) representing location information is set for the target object along with material information. Note that here, the color number may be changed depending on the location as described above, or the location information may be linked to the color number with a suffix, etc.

[0042] [If location information is not included] Step S108: If location information is not included, the color information specified in step S102 is set for the target object. As a result, color information (color number) representing material information is set for the target object.

[0043] Step S110: Next, determine whether to adjust the display colors of the BIM model. This determination can also be made based on the initial settings of the BIM tool 110. For example, if the initial settings are set to "make high-contrast material colors transparent" (Yes), then execute step S112. If the initial settings are not set (No), proceed directly to step S114.

[0044] Step S112: Here, transparency is set for the color information set in step S106 or step S108. When transparency is set, the display color becomes transparent when displaying material information in color on the BIM model.

[0045] Step S114: Then, the set color information is stored in the storage unit 118. After completing the above steps, the BIM tool 110 exits this process and returns to the previous process.

[0046] [Example of BIM model image display] 3 is a schematic diagram showing an example of an image display of a BIM model. Here, examples are given in which the display processing unit 114 of the BIM tool 110 displays the BIM model in (A) an exterior texture pattern and (B) a material color information pattern. The display processing unit 114 can switch between the two patterns as appropriate, for example, in response to an operation of the input unit 140. Note that while the interior of a building is used as an example here, the same applies to the exterior.

[0047] [Exterior texture display] In Figure 3 (A): In the pattern displaying the exterior texture, each object of the BIM model is displayed on the display unit 130 with the appearance of the finishing materials at the time of design. In this case, the interior of the building's standard wall WL1, decorative wall WL2, ceiling CL, floor FL, and staircase ST is displayed with the appearance when each finishing material is used. This allows the appearance of the building's finishing materials to be visually recognized on the BIM model.

[0048] [Material color information display] In the pattern shown in Figure 3 (B): Material Color Information Display, each object in the BIM model is displayed on the display unit 130 in the display color of the set color information. In this case, the display color of the BIM model no longer represents the exterior (interior) of the building, but represents the type of finishing material used in places such as walls WL1, decorative walls WL2, ceilings CL, floors FL, and stairs ST using color information. This makes it easy to see the materials used for the building's finishing materials on the BIM model as color information. In addition, when contrast is high, visibility can be improved by appropriately setting transparency to the color information.

[0049] [Overall processing sequence] 4 is a diagram showing an example of the processing sequence of the entire material calculation system 100, including the processing by the BIM tool 110 and the processing by the cost estimation program 120. The entire processing sequence will be explained below. Note that only an outline of the processing that has already been explained will be given.

[0050] [BIM tool processing] Step S1: The building to be constructed is designed using the BIM tool 110, and a BIM model is generated. Step S2: As described above, color information is set for each object on the BIM model and material information is linked. Step S3: The number of objects with color information set is tallied and an intermediate file MF is generated. At this time, by tallying the objects with the color information set on the BIM model, the total area of ​​the objects in the BIM model linked to the color information is extracted. Step S4: The generated intermediate file MF is output (provided) to the integration program 120, and the integration program 120 is called and started.

[0051] [Integration program processing] Step S5: The search processing unit 122 searches the finishing material database 124 using the color information linked to the finishing material (material) based on the intermediate file MF as a keyword, and calculates the required quantity of the finishing material to be used according to the area. Step S6: Then, the calculated results are output to an accumulation result file RF.

[0052] This allows the amount of material required for finishing the interior and exterior of a building to be output to the cost estimation result file RF, significantly reducing the amount of work required for cost estimation. In addition, the creation of the intermediate file MF and cost estimation result file RF is performed using simple calculations, reducing the processing load on the design computer and allowing cost estimation results to be obtained quickly and easily.

[0053] [Reversible Processing Sequence] With the above, the processing of the material calculation system 100 as a whole has been completed from the input stage to the output stage. In addition, in this embodiment, if any changes or other operations are made to the cost estimation result file RF after output, a processing sequence is performed to reversibly reflect those changes in the BIM model.

[0054] [Integration program processing] Step S7: The cost estimation program 120 updates the cost estimation result file RF as appropriate. For example, a designer may review the contents of the cost estimation result file RF and change the types of interior and exterior finishing materials in the cost estimation result file RF. In such a case, the cost estimation file management unit 126 updates the contents of the cost estimation result file RF through the operation of the input unit 140. Step S8: Based on the updated integration result file RF, the search processing unit 122 searches the finishing material database 124 for color information corresponding to the updated material information. At this time, the search for color information may include information about the location where the type of finishing material was changed. Step S9: The search results for color information are notified to the BIM tool 110 (object color information update notification). This notification includes location information of the object whose material information has been changed as described above, so that the target object can be easily identified on the BIM tool 110 side.

[0055] [BIM tool processing] Step S10: The BIM tool 110 reflects the color information of the object specified in the object color information update notification in the BIM model. When the color information of the object is changed on the BIM model, the material information of the finishing material is also changed on the BIM model in conjunction with this. This means that reversible feedback is automatically performed within the material calculation system 100, even if the designer does not make any changes to the BIM model again, thereby reducing the amount of work required.

[0056] A similar processing sequence is repeated thereafter, and during this time, if a change is made to the BIM model on the BIM tool 110 side, the result is reflected on the estimation program 120 side, and a processing sequence is executed in which the estimation result file RF is updated, or the opposite processing sequence is executed.

[0057] The material counting system 100 according to the above-described embodiment has the following advantages. (1) It is now possible to easily visually recognize the finishing material information in the BIM model as color information. In conventional BIM model designs, finishing material information was set as text data in the material information of each object, which was inconvenient because it was not possible to determine the finishing material without looking at the material information of each object. However, in this embodiment, the material can be easily determined from the BIM model image displayed on the display unit 130.

[0058] (2) When creating a BIM model, material information can be easily linked simply by setting color information for each object, so designers do not need to set detailed finishing material information for each object.

[0059] (3) By simply extracting color information from the BIM model, the quantity of objects can be easily calculated. As a result, the total amount of finishing materials, the locations where they are used (location information), and the total amount for each location can be automatically calculated.

[0060] The present invention is not limited to the above-described embodiment and can be implemented in various modifications. For example, the material calculation system 100 can be configured with multiple computers, with a design computer having the functionality of the BIM tool 110 and another computer having the functionality of the cost estimation program 120, and data can be transmitted and received between the multiple computers.

[0061] The BIM tool 110 may generate the intermediate file MF in a readable (language-based) file format or in an unreadable file format. Furthermore, when a readable intermediate file MF is generated, the intermediate file MF may or may not be displayed on the display unit 130.

[0062] The cost estimation program 120 may construct the finishing material database 124 in the internal storage area of ​​the design computer, or in an external storage device. Also, if the search processing unit 122 can manage updates to the cost estimation result file RF, the cost estimation file management unit 126 may not be configured.

[0063] The estimation file management unit 126 may be configured to be able to update the estimation result file RF displayed on the display unit 130 by operating a GUI or the like. In this case, the BIM tool 110 may be configured to reflect the update results in the BIM model in real time, and the color information of the BIM model may be updated in real time on the display unit 130, so that changes to the estimation result file RF can be intuitively recognized.

[0064] In one embodiment, the interior of a building is exemplified, but the present invention can also be applied to exterior finishing such as exterior walls and roofs. Furthermore, the building is not limited to a residential building, and the present invention can be applied to any type of building. Therefore, it goes without saying that the present invention can also be applied when planning the construction of an office building, a hotel, a logistics warehouse, a commercial facility, a multi-story parking lot, etc. [Explanation of symbols]
