Description

[Technical field]

[0001] The present invention relates to a method for processing wooden boards, for example, for forming a plate-shaped building material from a wooden board such as a CLT panel. [Background technology]

[0002] Background Art It is known that buildings such as detached houses, apartment buildings, temporary housing, dormitories, lodging facilities, hospitals, and elderly care facilities have walls, floors, ceilings, etc. made of plank-like building materials formed from wooden boards such as CLT (Cross Laminated Timber) (see, for example, Patent Document 1).

[0003] The plate-shaped building materials used in such buildings are generally formed into a desired shape by processing large wooden boards using a processing machine at a processing plant or the like. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-44501 Summary of the Invention [Problem to be solved by the invention]

[0005] Before actually constructing a building, a BIM (Building Information Modeling) model is created on a computer using 3D CAD software to streamline and improve the efficiency of construction work. In this case, the BIM model also includes data on the shapes of the plate-like building materials that make up the walls, floors, ceilings, etc.

[0006] However, even if a BIM model was created, when processing wooden boards using a processing machine to form plate-shaped building materials, new data on the shape of the plate-shaped building materials, etc., had to be created in a format specific to the processing machine, making the production work complicated.

[0007] The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for processing wooden boards that makes it possible to easily carry out the work of producing plate-shaped building materials. [Means for solving the problem]

[0008] The wooden board processing method of the present invention is a wooden board processing method for processing wooden boards into plate-shaped building materials to be used in buildings, and is characterized in that it includes a data conversion process for converting data of the plate-shaped building material contained in a BIM model of the building into processing machine data that can be used by a processing machine via a general-purpose data format, and a processing process for processing the wooden board with the processing machine using the processing machine data to form the plate-shaped building material.

[0009] In the wood board processing method of the present invention having the above configuration, it is preferable that the general-purpose data format includes the ACIS format. Effect of the Invention

[0010] According to the present invention, a method for processing wooden boards can be provided that makes it possible to easily carry out the work of producing plate-shaped building materials. [Brief description of the drawings]

[Figure 4] FIG. 4 is a flow chart showing more specific steps of the method for processing a wooden board according to the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for processing a wooden board according to an embodiment of the present invention will now be described in detail with reference to the drawings.

[0013] A method for processing a wooden board according to one embodiment of the present invention is a method for processing a wooden board into a planar building material to be used in a building structure.

[0014] The buildings in which the plate-shaped building materials are used may be various buildings such as detached houses, apartment buildings, temporary housing, dormitories, accommodation facilities, hospitals, and nursing homes for the elderly.

[0015] As shown in Fig. 1, in this embodiment, the wooden board material 1 is a large rectangular CLT (Cross Laminated Timber) panel with a constant thickness. A CLT panel is a wooden laminated board material formed by laminating multiple sawn boards 1a so that the grain directions of the boards are perpendicular to each other and gluing them together.

[0016] In this embodiment, a CLT panel is used as the wooden board 1, but the present invention is not limited to this, and various wooden boards, such as LVL (Laminated Veneer Lumber: a wooden laminated board formed by laminating multiple sawn boards 1a with the grain direction aligned and gluing them together) panels, boards made of solid wood or laminated wood, etc. may be used as the wooden board 1. The shape, size, etc. of the wooden board 1 can also be changed in various ways.

[0017] The plate-shaped building material 2 shown in Fig. 2 is formed into a predetermined shape by processing (trimming) a wooden board 1. In this embodiment, the plate-shaped building material 2 is combined with other plate-shaped building materials to form the framework of a building (not shown) when constructing the building, and has two rectangular recesses 2a and multiple holes 2b (for convenience, only one is marked in Fig. 2) that become combination parts with other plate-shaped building materials.

[0018] In this embodiment, the plate-shaped building material 2 constitutes the framework of a building, but it is not limited thereto, and may be any material used as a building material for a building, such as a wall material or ceiling material for a building. In addition, the shape and size of the plate-shaped building material 2, as well as the arrangement and number of the holes 2b, can be modified in various ways as long as it is used as a building material for a building.

[0019] Before a building is actually constructed using the plate-shaped building materials 2, a Building Information Modeling (BIM) model is created on a computer using 3D CAD software (e.g., "Revit" (registered trademark)). The BIM model of the building contains data on the shape of the plate-shaped building materials 2 used in the building.

[0020] In the method for processing wooden boards in this embodiment, when processing wooden boards 1 with a processing machine to form plate-shaped building material 2, data is linked between the processing machine and the BIM model of the building created on a computer, making it easy to process the plate-shaped building material 2 without the need to newly create data such as the shape of the plate-shaped building material 2 in a format specific to the processing machine, as was previously required.

[0021] Specifically, as shown in FIG. 3, the method for processing a wooden board according to this embodiment includes a data conversion step S1 and a processing step S2.

[0022] In the data conversion process S1, the data of the plate-shaped building material 2 included in the BIM model of the building is converted into data for a processing machine that can be used by a processing machine through a general-purpose data format. Note that the data of the plate-shaped building material 2 included in the BIM model is three-dimensional shape data of the plate-shaped building material 2.

[0023] As shown in Figure 4, in this embodiment, in the data conversion process S1, a BIM model of a building is created on a computer 3 using 3D CAD software (Revit (registered trademark)), and then the data of the plate-shaped building material 2 included in the BIM model is converted into a general-purpose data format by the computer 3, output, and transferred to a computer 4 at the processing plant where processing is performed.

[0024] It is preferable to use the ACIS format (.sat) as a general-purpose data format used in the data conversion step S1. The ACIS format can decompose faces and bodies into separate files and reconstruct them before outputting data of parts or components included in the BIM model, so that the data of the plate-shaped building material 2 included in the BIM model can be converted into ACIS format data with high accuracy.

[0025] When the processing plant computer 4 receives the data for the plate-shaped building material 2 in ACIS format (.sat), data correction work may be performed on the computer 4, such as adding identification marks for the decorative surface and markings to indicate fastening holes to be used when transporting the plate-shaped building material 2.

[0026] The general-purpose data format used in the data conversion step S1 is not limited to the ACIS format (.sat), and may be another data format.

[0027] In this embodiment, the data of the plate-shaped building material 2 that has been converted into a general-purpose data format and transferred to the computer 4 at the processing plant is converted into a data format for CAD software by the computer 4. In this embodiment, the CAD software is "Cadwork", a 3D CAD made by CADWORK.

[0028] The computer 4 at the processing plant may use CAD software to modify the data of the plate-shaped building material 2. In this embodiment, the computer 4 uses CAD software to modify the data for the processing machine of the plate-shaped building material 2, such as by adding hole drilling instructions and numbering the materials. Also, the computer 4 at the processing plant may use the CAD software to check whether the processing machine can accurately process the wooden board 1 into the plate-shaped building material 2 of a predetermined shape.

[0029] Next, the data of the plate-shaped building material 2 is transferred from the computer 4 to a computer 5 for the processing machine equipped with processing machine software (e.g., "EasyWood"). At this time, the data of the plate-shaped building material 2 is preferably converted to Btl format and transferred to the computer 5 for the processing machine. By converting the data of the plate-shaped building material 2 to Btl format, the data of the plate-shaped building material 2 can be transferred to the computer 5 for the processing machine with high accuracy. The data of the plate-shaped building material 2 input to the computer 5 is data for the processing machine that can be used by the processing machine.

[0030] After loading the data of the plate-shaped building material 2 into the processing machine software in the processing machine computer 5, information about the processing machine, etc. can be further input into the processing machine computer 5 to perform a simulation on the computer 5 to confirm the processing accuracy.

[0031] In this way, in the data conversion process S1, the data of the plate-shaped building material 2 contained in the BIM model is converted into data for the processing machine 6 that can be used by the processing machine 6 via multiple general-purpose data formats, including the general-purpose data format ACIS format (.sat).

[0032] Next, in the processing step S2, the data of the plate-shaped building material 2 whose data format has been converted in the data conversion step S1 and which has been input to the computer 5 for the processing machine, i.e., the data for the processing machine, is output to the processing machine 6. The processing machine 6 to which the data for the processing machine has been input operates according to the data for the processing machine to process the wooden board 1 into a predetermined shape. When the processing of the wooden board 1 is completed by the processing machine 6, the production of the plate-shaped building material 2 having the same shape as that in the BIM model is completed.

[0033] The processing machine 6 used in the processing step S2 can be of various types as long as it can operate according to processing machine data and process the wooden board 1 into a predetermined shape.

[0034] Thus, according to the wood board processing method of this embodiment, in the data conversion step S1, the data of the plate-shaped building material 2 included in the BIM model of the building is converted into data for processing machine usable by the processing machine 6 via a general-purpose data format, so that data for processing machine can be created accurately and easily from the data of the plate-shaped building material 2 included in the BIM model. Therefore, it is not necessary to newly create data on the shape of the plate-shaped building material 2 in a format dedicated to the processing machine separately from the BIM model, and the production work of the plate-shaped building material 2 can be easily performed.

[0035] Furthermore, according to the method for processing wood boards in this embodiment, there is no need to create new data for the shape of the plate-shaped building material 2 in a format specific to the processing machine, which makes it possible to simplify and reduce the labor required for producing the plate-shaped building material 2, and also shortens the production schedule for the plate-shaped building material 2, including the creation or drawing of the data.

[0036] Furthermore, according to the method for processing wooden boards in this embodiment, the BIM model can be accurately converted to create data for the processing machine without creating new data for the shape of the plate-shaped building material 2 in a format specific to the processing machine, thereby improving the quality of the plate-shaped building material 2 formed by processing the wooden board with the processing machine 6 using the data for the processing machine.

[0037] Furthermore, according to the method for processing wood boards in this embodiment, the BIM model can be converted into data for a processing machine with high accuracy, which makes it easy to check whether the data for the plate-shaped building material 2 contained in the BIM model matches the converted data for the processing machine.

[0038] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention.

[0039] For example, in the above embodiment, in the data conversion process S1, the data of the plate-shaped building material 2 included in the BIM data is converted into data for a processing machine through multiple conversions into a general-purpose data format, but this is not limited to the above, and as long as the data of the plate-shaped building material 2 included in the BIM data is converted into data for a processing machine through a general-purpose data format at least once, the number of conversions through the general-purpose data format can be changed in various ways.
