Description

The present invention relates to a material tallying system suitable for tallying materials used for buildings.

Conventionally, there is known a prior art of a system for calculating the quantity of building materials from BIM information of a building (for example, see Patent Document 1). This system acquires the shape of each part of the building model, the dimensions of the building materials used for each part, and the construction information from the storage unit, and uses this information to obtain the building model used for each part of the building model. Execute the process of calculating the quantity of materials for use.

According to the system of the prior art, the building model information can include all the shapes of the columns and walls that are the structures, the dimensions of the building materials, and their construction information. It is conceivable that the quantity of materials can be automatically calculated.

Japanese Patent Application Laid-Open No. 2020-119240

However, the above-described prior art system first acquires shape information such as the area of each part and the length of each side (distance between walls) from the building model, and then acquires the interior materials used for each part. After acquiring the dimensional information such as thickness, width, length, etc. of the base material, and also acquiring the construction standards to be observed when constructing the interior material in each part, the shape information and dimensional information are used to determine the base material. It requires complicated arithmetic processing such as calculating the quantity, or calculating the quantity of the base material in consideration of the work procedure that satisfies the construction standards when allocating the base material. Therefore, there is a problem that it takes a long time to complete the arithmetic processing, and the load increases accordingly.

Also, prior art systems require an enormous amount of information as a prerequisite for their computational processing. For this reason, when creating a BIM model, it is necessary to input detailed information such as materials and interior finishing materials for each structural object. In addition, since the information entered in this way becomes embedded information such as text data for each object, the contents cannot be easily visually recognized on the BIM model. It is necessary to open and check the embedded information one by one.

Accordingly, the present invention provides a system with improved convenience.

The present invention provides a material tallying system. It should be noted that the following parentheses are for reference and the like, and do not limit the present invention in any way.

The material tallying system of the present invention comprises setting means and tallying means. The setting means sets information on the materials used for the interior and exterior of the building as color information for objects of the interior and exterior on the BIM model. material information) as color information for the object. By setting the color information to a unique value that differs for each type of material used, all types of materials (product name, product number, etc.) can be represented by color information. In addition, you may set transparency together with color information. The color information may also include location information such as walls, floors, and ceilings regarding the object. The aggregation means extracts color information from the BIM model using a general-purpose program such as a BIM tool, and displays the color information in the form of a list of surface areas (possibly including position information) of objects for which color information is set (possibly including position information) and the total area. Aggregate the quantity of objects for which information is set.

As a result, the totaled number of objects directly represents the number of materials (such as interior and exterior finishing materials) that correspond to the color information used, so it is possible to easily total the required number of materials. . In addition, since the number of objects can be calculated simply from color information, it is possible to quickly calculate the number of objects without the need for particularly complicated arithmetic processing. In this way, by linking the material information to the color information and setting it, the material type (position coordinates).

Further, at the stage of creating a BIM model, the designer only needs to set the color information for the object, and does not have to set the finishing material information as embedded information for each object. For example, there is no need to manually set information such as "cloth number xx, paint number xx, tile number xx, flooring number xx" as text data in the material information of each object. Since the color information set for the object on the BIM model is information that can be visually recognized (recognized through vision) when the BIM model is displayed on the screen, the material information (interior and exterior) of the object can be easily displayed on the screen. What is the material used for ) can be confirmed.

Furthermore, the material tallying system can generate an intermediate file from the result of tallying the quantity of objects for which color information is set from the BIM model. This intermediate file can be output in a format (data format such as a list) in which the total number of objects is associated with color information.

The material tallying system comprises a calculating means. The calculation means calculates the amount of materials used for finishing the interior and exterior of the building using the color information in the intermediate file. Color information can also include the type of material used (product name, product number, etc.) and the location of use (walls, floors, ceilings, stairs, roofs, etc.). It is possible to quickly and easily tabulate the usage amount (accumulated amount) of the material in a form of listing all information for each item.

Preferably, the material tallying system can have a finishing material database in which material information corresponding to color information is registered. As a result, by searching for material information from the finishing material database using the color information in the intermediate file, it is possible to calculate the amount of material used for interior and exterior finishing based on the total number of objects. can. In addition, the product number of the material (finishing material) used and the cumulative amount for each place of use are calculated (area for cloth, tiles, flooring, etc.; for coating agents such as paint, the amount converted to square meters), and finishing It is also possible to generate a list of locations where lumber is used. It should be noted that the amount of loss per unit area of the material (irregular shape, cut ends, mistakes, etc.) can be set as a correction parameter for the integrated amount.

The material tallying system of the present invention can output calculated results as data. That is, based on the result of calculating the number of objects, the usage amount of materials (finishing materials) necessary for finishing the interior and exterior of the building is output in a file format associated with color information. At this time, since the color information also includes information such as the type of material and the place of use, as described above, it is possible to list the amount of use of the material for each type and place of use and output it as a file. . This output file results in the total amount of material required to finish the interior and exterior of the building.

So far, the material tallying system of the present invention has been output from the input stage, such as setting the color information of the object corresponding to the material from the creation of the BIM model of the building, calculating the number of objects, and outputting the material usage amount file. A process flow that works well in the direction of the steps is presented. Additionally, the material aggregation system of the present invention can also function reversibly from the output stage to the input stage.

That is, when the output file is processed to change the material information, the material collection system converts the color information of the set object to the color information corresponding to the changed material information on the BIM model. can be updated. For example, if the type of material at a certain place of use is changed on the output file, the setting of the object at the corresponding place of use on the BIM model is updated to the color information representing the changed type of material. Therefore, if an operation such as a change is added to the material information on the output file, the operation is reversibly fed back to the BIM model, so there is no need to return to the input stage and correct the BIM model.

The material tallying system of the present invention may have the following configuration.
(1) A display adjusting means capable of adjusting the display color of the BIM model based on the set color information of the object when displaying the image of the BIM model.
(2) The setting means can set transparency in combination with color information as a parameter used when displaying the image of the BIM model.
(3) The display adjustment means can adjust the display color of the BIM model according to the set color information and transparency.

With the configuration (1) above, when the BIM model is displayed as an image, it is possible to easily visually recognize the material information of the interior and exterior using the display color of the object.
According to the above configurations (2) and (3), the color information is easily visible on the BIM model. May impede visibility. Therefore, by setting the transparency in accordance with the color information and adjusting the display color of the BIM model, it is possible to realize an image display that does not interfere with visibility.

(4) The display adjustment means is capable of switching between texture display of objects representing the external appearance of the interior and exterior of a building and color display based on the color information of the objects set by the setting means when displaying images of the BIM model. It can be a certain thing.

According to the above configuration (4), it is possible to confirm the appearance (interior) of the building by using the BIM model as a texture display, and to confirm the finish material of the object by using the color display as a material representation. , further convenience can be improved.

As described above, according to the present invention, it is possible to provide a system with improved convenience.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following embodiments, a suitable example of the material tallying system is given, but the form of the present invention is not limited to the example.

[System configuration example]
FIG. 1 is a block diagram showing a configuration example of a material tallying system 100. As shown in FIG. The material collection system 100 is composed of, for example, a design computer. The computer for design may be a general-purpose computer device, regardless of the form such as a desktop type, a laptop type, a tablet type, or the like.

For example, a BIM tool 110 and an integration program 120 are installed in the design computer. Of these, the BIM tool 110 can be configured using a general-purpose program (eg, Revit: registered trademark). The integration program 120 is a dedicated application prepared for configuring the material counting system 100 together with the BIM tool 110 .

The design computer has a display unit 130 and an input unit 140 as peripheral devices. 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, mouse, or tablet.

The BIM tool 110 of the design computer can have, for example, an aggregation processing unit 112, a display processing unit 114, an object management unit 116, a storage unit 118, and the like. Of these, the tabulation processing unit 112 is a functional element optimized and customized for the material tabulation system 100. In addition to tabulating BIM model objects from color information, it also functions as an API when calling the accumulation program 120. can be done. The display processing unit 114 executes display control processing when displaying a BIM model or the like 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 storage unit 118 manages access to the hardware storage area of the design computer.

In the design computer, when the totalization processing unit 112 on the BIM tool 110 side totalizes the number of objects from the color information of the BIM model, the result is generated as an intermediate file MF. The aggregation processing unit 112 calls the integration program 120 and passes the generated intermediate file MF to the integration program 120 side.

[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 As the “color information”, for example, RGB color number, CMYK color number, LAB color number, etc. can be used as appropriate. The color number can be a unique value (color number #xxxx, etc.) that differs for each type of material, so the color number set for the object directly represents the type of material (product name, product number). . Therefore, the designer only needs to set (assign) a color number to each object on the BIM tool 110, and does not need to embed detailed material information as text data or the like for each object.
Also, transparency may be set in combination with color information. The transparency is useful for adjusting the contrast and the like and improving the visibility when the BIM model is displayed as an image on the display unit 130 .
Furthermore, the color information may include information on the location (wall, floor, ceiling, stairs, roof, coordinates, etc.) where the material is used. When including location information, (i) different color information (color number) is set for each location where the material is used, and (ii) location information is linked to the color information (color number) with a suffix When setting, there are two patterns.

(2) Cumulative amount (object quantity) list The "accumulated amount" referred to at the stage of the intermediate file MF is the number of objects (surface area, total area, etc.) for which color information is set, and the final amount of material used. isn't it. The number of objects is aggregated for each color number, and when location information is included in the color information, the number of objects is aggregated for each location.
This "accumulated amount" is listed for each object location, for example. For example, "coordinates/area name wall ... integrated amount xxx (m ² )", "coordinates/area name floor ... integrated amount xxx (m ² )", "coordinates/area name ceiling... integrated amount xxx (m ² )", Aggregation results such as "coordinates/area name stairs...total amount xxx (m ² )" are listed.

Also, such an intermediate file MF is generated for each color number if a plurality of color numbers (#xxxx, . . . ) are set.

The integration program 120 can have, for example, a search processing unit 122, a finishing material database 124, an integration file management unit 126, and the like. When the integration program 120 receives a call from the aggregation processing unit 112 on the BIM tool 110 side, the search processing unit 122 searches the material information from the finishing material database 124 based on the intermediate file MF, and calculates the integrated amount of finishing material (cloth , the area for tiles, flooring materials, etc., and the quantity in ^m2 for coating materials such as paint). In the finishing material database 124, finishing material information corresponding to color information (for example, finishing material product name, product number, unit price, etc.) is registered in advance. Note that the search processing unit 122 may set the amount of loss per area (deformed shape, scrap, mistake, etc.) as a correction parameter for each material. Then, the search processing unit 122 generates (outputs) a list of calculated integrated amounts as an integration result file RF.

[Example of integration 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 handed over to the integration result file RF.
(2) Finishing material (product name product number)
The material information (product name, product number, unit price, manufacturer, etc. of the finishing material) retrieved from the finishing material database 124 is output to the integration result file RF.
(3) Cumulative Amount List The cumulative result of the amount used (total area, total weight, etc.) for each type of finishing material is output to the cumulative result file RF. Cumulative quantities are also listed by interior and exterior locations. For example, "coordinates/area name wall ... integrated amount xxx (m ² )", "coordinates/area name floor ... integrated amount xxx (m ² )", "coordinates/area name ceiling... integrated amount xxx (m ² )", Aggregation results such as "coordinates/area name stairs...total amount xxx (m ² )" are listed. The integrated amount may be represented by the total number (xxx sets), the total weight (xxx kg), the total length (xxxm), or the like, or may be represented by the purchase price.

Note that the integration file management unit 126 executes data file control such as storage, external output, and update 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 by a printer on the network, or data can be shared with other computers. Also, the integration result file RF can be displayed on the display unit 130 of the design computer.

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

[Color information setting process]
FIG. 2 is a flow chart showing a procedure example of color information setting processing executed on the BIM tool 110 side. In this process, when a building (architecture, civil engineering, etc.) is designed using BIM (CAD), when combining objects to create a BIM (three-dimensional) model of the building, the material information of the objects to be used is By setting it as color information, it is possible to easily set information on finishing materials (interior and exterior). An example procedure will be described below.

Step S100: In the BIM tool 110, a target object is specified on the BIM model. For example, if the BIM model is a collective housing building, the object such as an outer wall object and an inner wall object is specified.

Step S102: Designate the material information used for finishing the interior or exterior of the designated target object in association with the color information. The color information corresponding to the finishing material (material) is presented in advance to the designer on the BIM tool 110 in the form of list data or the like. For this reason, the designer only needs to set the color information for the target object when specifying the materials used for finishing the interior and exterior on the BIM model. Alternatively, color information may be copied and pasted from another set object.

Step S104: It is determined whether or not to include the location information of the object in the color information. This determination can be made, for example, based on the initial setting of the BIM tool 110. 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 (separately set)" (No), then step S108 is executed.

[When including location information in color information]
Step S106: Set the color information of 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 together with material information. 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 by a suffix or the like.

[When location information is not included]
Step S108: If the 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.

Step S110: Next, it is determined whether or not to adjust the display color of the BIM model. This determination can also be made, for example, based on the default settings of the BIM tool 110. If the default settings are, for example, "Make high-contrast material colors transparent" (Yes), then step Execute S112. If the above initial settings are not set (No), the process proceeds to step S114.

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

Step S<b>114 : Then, the set color information is saved in the storage unit 118 .
After completing the above procedure, the BIM tool 110 exits this process and returns to the previous process.

[BIM model image display example]
FIG. 3 is a schematic diagram showing an image display example of a BIM model. In this example, the display processing unit 114 of the BIM tool 110 displays a BIM model in (A) an appearance texture display pattern and (B) a material color information display pattern. The display processing unit 114 can appropriately switch between the two patterns according to the operation of the input unit 140, for example. Although the interior of the building is taken as an example here, the same applies to the exterior.

[Appearance texture display]
(A) in FIG. 3: In the pattern displayed with the appearance texture, each object of the BIM model is image-displayed on the display unit 130 with the appearance of the finishing material at the time of design. In this case, the standard wall WL1, the decorative wall WL2, the ceiling CL, the floor FL, and the interior of the staircase ST of the building are displayed with their appearance when using the respective finishing materials. This makes it possible to visually recognize the appearance of the finishing materials of the building on the BIM model.

[Material color information display]
(B) in FIG. 3: In the pattern in which the material color information is displayed, each object of the BIM model is image-displayed on the display unit 130 in the display color of the set color information. In this case, the display colors of the BIM model no longer represent the external appearance (interior view) of the building, and the types of finishing materials used for locations such as wall WL1, decorative wall WL2, ceiling CL, floor FL, and stairs ST are color information. is represented by As a result, it is possible to easily visually recognize the material used for the finishing material of the building on the BIM model as color information. Further, when the contrast is high, the visibility can be improved by appropriately setting the transparency of the color information.

[Overall processing sequence]
FIG. 4 is a diagram showing an example of a processing sequence of the entire material tallying system 100 including processing by the BIM tool 110 and processing by the integration program 120. As shown in FIG. The overall processing sequence will be described below. It should be noted that the already explained processing is only an outline.

[BIM tool side processing]
Step S1: Design a building to be constructed with the BIM tool 110 and generate a BIM model.
Step S2: As described above, color information is set for each object on the BIM model, and material information is linked.
Step S3: Aggregate the number of objects for which color information is set, and generate an intermediate file MF. At this time, the total area of the objects in the BIM model linked to the color information is extracted by counting the objects by focusing on the color information set on the BIM model.
Step S4: Output (provide) the generated intermediate file MF to the integration program 120 side, and call and activate the integration program 120 .

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

As a result, the amount of materials used for finishing the interior and exterior of the building is output to the integration result file RF, so that the number of man-hours required for the integration work can be greatly reduced. In addition, since the intermediate file MF and the integration result file RF are both generated by simple arithmetic processing, the processing load on the design computer can be reduced, and the integration result can be obtained quickly and easily.

[Reversible processing sequence]
Thus, the processing of the material tallying system 100 as a whole has been completed from the input stage to the output stage. In addition, in this embodiment, after the output, operations such as changes are performed on the integration result file RF. Then, a processing sequence is performed to reversibly reflect the change in the BIM model.

[Integration program side processing]
Step S7: On the integration program 120 side, the integration result file RF is appropriately updated. For example, as a result of examining the contents of the integration result file RF by a designer or the like, there are cases where the types of interior and exterior finishing materials are changed on the integration result file RF. In such a case, the content of the integration result file RF is updated by the integration file management unit 126 through the operation of the input unit 140 .
Step S8: The search processing unit 122 searches the finishing material database 124 for color information corresponding to the updated material information based on the updated integration result file RF. At this time, the color information may be retrieved including the information of the location where the type of finishing material is changed.
Step S9: Notify the BIM tool 110 side of the color information search result (object color information update notification). Since this notification includes the location information of the object whose material information has been changed as described above, the BIM tool 110 can easily identify the target object.

[BIM tool side processing]
Step S10: On the BIM tool 110 side, the color information of the object specified in the object color information update notification is reflected 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. As a result, even if the designer does not change the BIM model again, reversible feedback is automatically performed inside the material collection system 100, and man-hours can be reduced accordingly.

Thereafter, the same processing sequence is repeated, and during that time, when a change is made to the BIM model on the BIM tool 110 side, the result is reflected on the integration program 120 side, and a processing sequence is executed in which the integration result file RF is updated. or the reverse processing sequence may be performed.

According to the material tallying system 100 of the embodiment described above, the following usefulness is exhibited.
(1) It becomes possible to easily visually recognize finishing material information in the BIM model as color information. In this regard, in conventional BIM model design, finishing material information was set as text data in the material information of each object. In this embodiment, the material can be easily determined from the BIM model displayed as an image on the display unit 130 .

(2) When creating a BIM model, simply by setting color information for each object, the material information can be easily linked, so the designer does not need to finely set finishing material information for each object.

(3) The number of objects can be easily totaled simply by extracting color information from the BIM model. As a result, it is possible to automatically calculate the integrated amount of the finishing material, the place of use (positional information), and the integrated amount for each place of use.

The present invention can be modified in various ways without being restricted by the above-described embodiments. For example, the material counting system 100 can be configured with a plurality of computers. Data may be sent and received between computers.

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

The integration program 120 may build the finishing material database 124 in the internal storage area of the design computer, or may build it in an external storage device. Further, if the update of the integration result file RF can be managed in the search processing unit 122, the configuration of the integration file management unit 126 may be omitted.

The integration file management unit 126 may update the integration result file RF displayed on the display unit 130 by operating a GUI or the like. In this case, on the BIM tool 110 side, the update result is reflected in the BIM model in real time, and the color information of the BIM model is updated in real time on the display unit 130, so that the change in the integration result file RF can be intuitively visually recognized. It is good also as a structure which becomes.

In one embodiment, the interior of a building is exemplified, but the present invention can also be applied to exterior finishes such as outer walls and roofs. Moreover, the construction is not limited to a residential building, and can be applied to any type of building. Therefore, it goes without saying that the present invention can also be applied when planning construction of office buildings, hotels, distribution warehouses, commercial facilities, multilevel parking lots, and the like.
