Description

[Technical field]

[0001] The present disclosure relates to a system for forming processing information for wood in buildings and a processing information forming program. [Background technology]

[0002] It is known that in wooden buildings, processing data for wood is generated by a calculation system. For example, in the technology described in Patent Document 1, master data is used to generate processing data for wood. In the technology described in the same document, design data for metal fittings that are automatically changed according to the extension direction of each piece of wood is generated, and processing data for multiple pieces of wood to be joined according to the automatically changed design data for the metal fittings is generated.

[0003] [Patent Document 1] JP 2018-156630 A Summary of the Invention [Problem to be solved by the invention]

[0004] In a building, a number of metal fittings may be connected to a wooden shaft, which is a structural member of the building. In this case, the positions of the bolts on the wood that secure the metal fittings to the wooden shaft are set so that they do not interfere with each other. However, setting the positions of such bolts is time-consuming. For this reason, there is room for improvement in the creation of processing data for wooden shafts from the viewpoint of work efficiency. [Means for solving the problem]

[0005] (1) A processing information formation system that solves the above-mentioned problems is a processing information formation system that forms hole formation information for a wooden shaft, and includes an information acquisition unit and a processing information formation unit. The information acquisition unit acquires wooden shaft information, hardware information of hardware connected to the wooden shaft, and fixing position information that indicates fixing positions of the hardware relative to the wooden shaft. The processing information formation unit executes the following steps: a grouping process that groups hardware whose hole positions overlap in the height direction when the hardware is placed on the wooden shaft based on the hardware information and the fixing position information; a hole candidate setting process that sets bolt hole candidates for fixing the hardware in the group based on the hardware information of each hardware in the group; and a selection process that selects bolt holes that satisfy the fixing conditions of the hardware from the bolt hole candidates.

[0006] Conventionally, hole positions have been set on a wooden shaft without grouping metal fittings whose bolt hole positions overlap. For example, bolt holes are set in the order of the number of bolt holes in the metal fittings. With this setting method, the last metal fitting remaining may not satisfy the metal fitting conditions. In this case, it becomes necessary to review the bolt hole positions for all metal fittings. In this regard, the above configuration performs a grouping process that groups metal fittings whose bolt hole positions overlap, so that hole positions can be determined for each group. This reduces the need to redo the setting of hole positions. In this way, the work efficiency in forming processing data for wooden shafts can be improved.

[0007] (2) In the processing information forming system of (1) above, the wooden shaft has a first side, a second side, a third side opposite the first side, and a fourth side opposite the second side, and the processing information forming unit, in the grouping process, classifies the grouped metal fittings that are arranged on the first side and the third side into a first subgroup and classifies the grouped metal fittings that are arranged on the second side and the fourth side into a second subgroup, in the hole candidate setting process, sets a first bolt hole candidate in the first subgroup and sets a second bolt hole candidate in the second subgroup, and in the selection process, selects bolt holes from each of the first bolt hole candidates and the second bolt hole candidates so that a bolt hole selected from the first bolt hole candidates and a bolt hole selected from the second bolt hole candidates do not interfere with each other and so as to satisfy the fixing conditions of the metal fittings.

[0008] If bolt hole candidates are set independently for each of the multiple metal fittings attached to the wooden shaft, the number of options when selecting bolt holes that do not interfere with each other increases, which may result in complicated calculations. In this regard, according to the above configuration, the first subgroup and the second subgroup are groups of metal fittings that are positioned opposite each other with respect to the wooden shaft. Then, bolt hole candidates are set independently for each of the first subgroup and the second subgroup. This reduces the number of options when selecting bolt holes, improving calculation efficiency.

[0009] (3) In the processing information forming system described in (1) above, in the grouping process, the processing information forming unit creates groups by repeating a group association process for the fasteners in the order of the arrangement of the fasteners in the height direction, and in the group association process, if the position of any one of the fastener holes of a fastener that is the subject of the grouping process overlaps with the position of the fastener hole of at least one fastener that belonged to the group before the fastener in question, the processing information forming unit belongs to the group.

[0010] Even if two of the multiple metal fittings are separated in the height direction, the two metal fittings and the other metal fittings may belong to one group depending on their relationship with the other metal fittings. Therefore, if one metal fitting is used as a reference and grouped only based on the relationship between the metal fittings and the other metal fittings, there is a risk that the two metal fittings separated in the height direction will not belong to the same group. In this regard, the above configuration can prevent metal fittings that should be grouped from being removed from the group. In this way, the metal fittings can be grouped appropriately.

[0011] (4) In the processing information forming system described in (1) above, the processing information forming unit further includes a bolt hole type determination process, and in the bolt hole type determination process, the processing information forming unit sets the type of bolt hole for each of the bolt hole candidates or each of the selected bolt holes based on the positional relationship of the metal fittings. With this configuration, the type of bolt hole can be set.

[0012] (5) In the processing information forming system described in (4) above, the wooden shaft has a first side, a second side, a third side opposite the first side, and a fourth side opposite the second side, and in the grouping process, the processing information forming unit classifies, among the grouped metal fittings, metal fittings arranged on the first side and the third side into a first subgroup and classifies, among the grouped metal fittings, metal fittings arranged on the second side and the fourth side into a second subgroup, in the hole candidate setting process, sets a first bolt hole candidate in the first subgroup and sets a second bolt hole candidate in the second subgroup, and in the selection process, selects bolt holes from each of the first bolt hole candidates and the second bolt hole candidates so that a bolt hole selected from the first bolt hole candidates and a bolt hole selected from the second bolt hole candidates do not interfere with each other and so as to satisfy the fixing conditions of the metal fittings.

[0013] According to this configuration, the first subgroup and the second subgroup are groups of metal fittings that are located on opposite sides of the wooden axis. Then, bolt hole candidates are set independently for the first subgroup and the second subgroup. This reduces the number of options when selecting bolt holes, improving calculation efficiency.

[0014] (6) In the processing information forming system described in (5) above, the processing information forming unit creates groups by repeating a group association process for the fasteners in the order of the arrangement of the fasteners in the height direction in the grouping process, and if the position of any one of the fastener holes of a fastener to be grouped in the group association process overlaps with the position of the fastener hole of at least one fastener that belonged to the group before the fastener, the fastener to be grouped is included in the group. This configuration makes it possible to prevent fasteners that should be grouped from being removed from the group. In this way, fasteners can be appropriately grouped.

[0015] (7) In the processing information forming system according to any one of (1) to (6) above, the processing information forming unit selects the bolt hole candidate based on fastening hole information included in the hardware information in the hole candidate setting process. With this configuration, it is possible to select the bolt hole candidate suitable for the hardware.

[0016] (8) A processing information formation program that solves the above-mentioned problems is a processing information formation program that causes a computer to form hole formation information in a wooden shaft, the processing information formation program including an information acquisition step and a processing information formation step, in which the information acquisition step causes the computer to acquire wooden shaft information, hardware information of hardware connected to the wooden shaft, and fixing position information that indicates fixing positions of the hardware relative to the wooden shaft, and the processing information formation step causes the computer to execute a grouping process that groups hardware whose hole positions overlap in the height direction when the hardware is placed on the wooden shaft based on the hardware information and the fixing position information, a hole candidate setting process that sets bolt hole candidates for fixing hardware in the group based on the hardware information of each hardware in the group, and a selection process that selects bolt holes that satisfy the fixing conditions of the hardware from the bolt hole candidates.

[0017] According to this configuration, a grouping process is performed to group metal fittings with overlapping hole positions, so the hole positions can be determined for each group. This reduces the need to reset the hole positions. In this way, the work efficiency in forming the processing data for the wooden shaft can be improved. Effect of the Invention

[0018] According to the present disclosure, the work efficiency in forming processing data for wooden shafts can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] A processing information forming system 40 according to the present embodiment will be described with reference to FIGS. 1 and 2, several other shaft members are connected to the wooden shaft 2 via metal fittings 10. The processing information forming system 40 calculates the wooden shaft 2 to which other shaft members are connected via metal fittings 10.

[0021] The processing information forming system 40 acquires the information formed by the structural design system 1 in order to form the hole formation information.

[0022] The structural design of a building is performed in a structural design system 1 separate from the processing information formation system 40. The processing information formation system 40 may be integrated into the structural design system 1. The structure of the building is designed in the structural design system 1. The following items are set in the structural design system 1. The items set in the structural design system 1 are the frame structure formed by the wooden shaft 2 and cross members, the dimensions of the wooden shaft 2, the dimensions of the cross members, the connection relationship at the connection between the wooden shaft 2 and the cross members, and the type of metal fittings 10 to be attached to the wooden shaft 2.

[0023] The wooden shaft 2 is a structural material of the building. The wooden shaft 2 includes a pillar. In this embodiment, the wooden shaft 2 does not include a stud. The wooden shaft 2 is connected to other structural materials via metal fittings 10. The other structural materials include cross members and other wooden shafts 2. The other structural materials may include gradient beams. Examples of cross members include beams and girders.

[0024] An example of the wooden shaft 2 will be described with reference to Figs. 2 to 5. The wooden shaft 2 shown in Fig. 2 is connected to a foundation. Fig. 3 is a diagram in which the wooden shaft 2 is omitted from Fig. 2. Fig. 4 is a cross-sectional view taken along line AA of the wooden shaft 2 in Fig. 2. Fig. 5 is a cross-sectional view taken along line BB of the wooden shaft 2 in Fig. 2.

[0025] A first metal fitting 11 for connecting a first cross member 21 to the wooden shaft 2 is connected to a first side surface 2A of the wooden shaft 2. A second metal fitting 12 for connecting a second cross member 22 to the wooden shaft 2 is connected to a second side surface 2B of the wooden shaft 2. A third metal fitting 13 for connecting a third cross member 23 to the wooden shaft 2 is connected to a third side surface 2C of the wooden shaft 2. A fourth metal fitting 14 for connecting a fourth cross member 24 to the wooden shaft 2 is connected to a third side surface 2C of the wooden shaft 2. A fifth metal fitting 15 for connecting a fifth cross member 25 to the wooden shaft 2 is connected to a third side surface 2C of the wooden shaft 2. A sixth metal fitting 16 for connecting a sixth cross member 26 to the wooden shaft 2 is connected to a fourth side surface 2D of the wooden shaft 2. A wooden shaft connecting shaft member 17 for connecting to other wooden shafts 2 is inserted in the vertical direction into the upper end surface 2E of the wooden shaft 2. A foundation metal fitting 18 is connected to a lower end surface 2F of the wooden shaft 2. The foundation metal fitting 18 connects the wooden shaft 2 to a foundation.

[0026] 2, the metal fitting 10 is fixed to the wooden shaft 2 by a bolt 20. The bolt 20 is inserted into a bolt hole 28 provided in the wooden shaft 2. A plurality of bolt holes 28 are formed in the wooden shaft 2. When a plurality of metal fittings 10 are connected to the wooden shaft 2, the bolt holes 28 are positioned so as not to interfere with each other. The processing information forming system 40 will be described below.

[0027] [Processing information formation system] The processing information forming system 40 forms hole formation information for realizing the state of the wooden shaft 2 shown in Figs.

[0028] As shown in FIG. 6, the processing information forming system 40 includes an information acquiring unit 41 and a processing information forming unit 42. A display unit 43 that displays a processing result is connected to the processing information forming unit 42. The processing information forming system 40 includes one or more CPUs (Central Processing Units) or MPUs (Micro Processing Units). The processing information forming system 40 may include one or more processors that execute various processes according to a computer program (software). The processing information forming system 40 may include a combination of the above-mentioned processors and hardware circuits. The processor includes a CPU and a memory such as a RAM and a ROM. The memory stores program codes or instructions configured to cause the CPU to execute processes. The memory, i.e., computer-readable media, includes any available media that can be accessed by a general-purpose or special-purpose computer.

[0029] The processing information forming system 40 forms hole formation information for the wooden shaft 2. The processing information forming system 40 forms hole formation information for the wooden shaft 2 based on information set by the structural design system 1. The hole formation information includes information regarding the number and arrangement of the bolt holes 28 in the wooden shaft 2.

[0030] [Information acquisition department] The information acquisition unit 41 acquires wooden shaft information, metal fitting information, and fixed position information. Hereinafter, the wooden shaft information, metal fitting information, and fixed position information are collectively referred to as "wooden shaft related information." The information acquisition unit 41 acquires wooden shaft related information for each of all or some of the wooden shafts 2 that constitute the framework structure of the building. In this embodiment, the wooden shaft related information is acquired from the structural design system 1.

[0031] The wooden shaft information is information about the shape of the wooden shaft 2. The wooden shaft information includes information about the dimensions of each face constituting the wooden shaft 2, the relationship between the faces, and the position of the wooden shaft 2 in the framework structure. For example, the wooden shaft 2 has a first side 2A, a second side 2B, a third side 2C opposite the first side 2A, and a fourth side 2D opposite the second side 2B. The wooden shaft 2 further has an upper end face 2E and a lower end face 2F. In this case, the wooden shaft information includes the dimensions of the first side 2A to the fourth side 2D and the positional relationship of the first side 2A to the fourth side 2D. The wooden shaft information may include information about the orientation of the first side 2A with respect to the reference direction of the building.

[0032] The hardware information is information about the hardware 10 connected to the wooden shaft 2. The hardware information is information about the hardware 10 set for the wooden shaft 2 by the structural design system 1. The hardware information includes the shape and dimensions of the hardware 10, the number of hardware holes 10A that the hardware 10 has, the positions of the hardware holes 10A that cannot be used for fastening (hereinafter, invalid hole positions), and the number of bolts required to fasten the hardware 10 to the wooden shaft 2 (hereinafter, required number of bolts). The required number of bolts is set based on a calculation of the connection strength between the wooden shaft 2 and the cross member. The required number of bolts is set by the structural design system 1.

[0033] The type of metal fittings 10 used with the wooden shaft 2 is preset. All usable metal fittings 10 have a common hole pitch (hereinafter, common hole pitch). The common hole pitch indicates the distance between two adjacent metal fitting holes 10A in the metal fitting 10. The metal fitting holes 10A are provided in the metal fitting 10 at a pitch that is an integer multiple of the common hole pitch. The processing information forming system 40 stores the common hole pitch.

[0034] The fixed position information indicates the fixed position of the metal fitting 10 relative to the wooden shaft 2. The fixed position of the metal fitting 10 indicates the position in the height direction from the reference plane of the wooden shaft 2. The reference plane of the wooden shaft 2 is the upper end surface 2E or the lower end surface 2F. The fixed position information is set based on the framework structure of the building. The fixed position information is set by the structural design system 1.

[0035] The fixing position of the metal fitting 10 is set in accordance with the position rule. According to the position rule, the fixing position of the metal fitting 10 is set at a distance from the reference surface of the wooden shaft 2 that is an integer multiple of the reference pitch. The reference pitch is equal to the common hole pitch. The position rule is shared by the structural design system 1 and the processing information forming system 40. This makes it easier to set bolt holes 28 that do not interfere with each other.

[0036] [Processing information formation department] The processing information forming unit 42 executes a grouping process, a hole candidate setting process, and a selection process. The processing information forming unit 42 may execute a bolt hole type determination process.

[0037] [Grouping process] In the grouping process, the processing information forming unit 42 groups the fittings 10 whose hole positions overlap in the height direction when the fittings 10 are placed on the wooden shaft 2 based on the fitting information and the fixed position information.

[0038] In the grouping process, the processing information formation unit 42 creates groups by repeating the group association process for the fittings 10 in the order in which the fittings 10 are arranged in the height direction.

[0039] In the group association process, if the position of any of the metal fitting holes 10A that are the subject of the grouping process overlaps with the position of at least one metal fitting hole 10A of a metal fitting 10 that belonged to a group before the metal fitting 10 in question, the processing information formation unit 42 assigns the target metal fitting 10 to a group.

[0040] An example of grouping will be described with reference to Fig. 7. In this embodiment, the processing information forming unit 42 executes grouping processing on the fittings 10 provided on the first side surface 2A to the fourth side surface 2D.

[0041] 7, the processing information forming unit 42 detects the presence or absence of metal fittings 10 on the wooden shaft 2 in the order of the first side surface 2A, the third side surface 2C, the second side surface 2B, and the fourth side surface 2D while proceeding downward a predetermined pitch from the top end surface 2E of the wooden shaft 2 to be calculated. The downward movement by the predetermined pitch is performed after the detection of the first side surface 2A to the fourth side surface 2D is completed. This makes it possible to repeat the group association process for the metal fittings 10 in the order of arrangement of the metal fittings 10 in the height direction.

[0042] Initially, the first group includes one element. Specifically, the metal fitting 10 at the highest position on the wooden shaft 2 belongs to the first group. For example, the first group initially includes the first metal fitting 11 on the first side surface 2A.

[0043] Next, the processing information forming unit 42 executes a group association process. Specifically, the processing information forming unit 42 detects the third fitting 13 on the third side surface 2C. At this time, it is determined whether the position of any of the holes of the third fitting 13 overlaps with the position of any of the holes of the first fitting 11 that belonged to the group before the fitting 10. If the position of any of the holes of the third fitting 13 overlaps with the position of any of the holes of the first fitting 11, the third fitting 13 is made to belong to the first group.

[0044] The processing information forming unit 42 repeats the group association process. Then, if the processing information forming unit 42 does not detect the fitting 10 four consecutive times, the processing information forming unit 42 completes grouping for the first group. Next, the processing information forming unit 42 forms a second group as a new group, and subsequently repeats the group association process.

[0045] 8, in this embodiment, the first group includes a first fitting 11, a second fitting 12, a third fitting 13, a fourth fitting 14, and a sixth fitting 16. The second group includes a fifth fitting 15.

[0046] After completing grouping of all the metal fittings 10 on the wooden shaft 2, the processing information forming unit 42 executes the following process.

[0047] As shown in FIG. 9, in the grouping process, the processing information forming unit 42 classifies, among the grouped fittings 10, the fittings 10 arranged on the first side surface 2A and the third side surface 2C into a first subgroup.

[0048] As shown in FIG. 10, in the grouping process, the processing information forming unit 42 classifies, among the grouped fittings 10, the fittings 10 arranged on the second side surface 2B and the fourth side surface 2D into a second subgroup.

[0049] [Hole candidate setting process] The hole candidate setting process will be described with reference to FIGS. In the hole candidate setting process, the processing information formation unit 42 sets bolt hole candidates for fastening the fittings 10 in the group based on the fitting information of each fitting 10 in the group. Here, the first group will be described.

[0050] As shown in FIG. 9, the processing information forming unit 42 sets a first bolt hole candidate X1 in the first subgroup. Specifically, processing information formation unit 42 sets first bolt hole candidate X1 based on fitting hole 10A of first fitting 11, fitting hole 10A of third fitting 13, and fitting hole 10A of fourth fitting 14. For first bolt hole candidate X1, all holes of fitting hole 10A of first fitting 11, fitting hole 10A of third fitting 13, and fitting hole 10A of fourth fitting 14 are set as bolt hole candidates. Among fitting hole 10A of third fitting 13 and fitting hole 10A of fourth fitting 14, fitting hole 10A that is at the same height as the hole of first fitting 11 in the height direction is the bolt hole candidate common to both fittings 10.

[0051] As shown in FIG. 10, the processing information forming unit 42 sets a second bolt hole candidate X2 in the second subgroup. Specifically, the processing information formation unit 42 sets second bolt hole candidates X2 based on the mounting hole 10A of the second mounting member 12 and the sixth mounting member 16. For the second bolt hole candidates X2, all of the mounting holes 10A of the second mounting member 12 and the mounting holes 10A of the fourth mounting member 14 are set as bolt hole candidates. Of the mounting holes 10A of the fourth mounting member 14, any hole that is at the same height in the height direction as the mounting hole 10A of the second mounting member 12 becomes a bolt hole candidate common to both mounting members 10.

[0052] Furthermore, in the hole candidate setting process, the processing information formation unit 42 selects bolt hole candidates based on the fastening hole information included in the metal fitting information. The fixing hole information includes information on holes (hereinafter, void holes 28D) that cannot be used as bolt holes 28 in the fitting 10. The fixing hole information includes information on the presence or absence of void holes 28D and the void hole positions of void holes 28D in the fitting 10. As one example, fitting hole 10A located at the uppermost position in the fitting 10 is set as void hole 28D.

[0053] When the fixing hole information includes void hole 28D, processing information forming unit 42 excludes void hole 28D from first bolt hole candidate X1 and second bolt hole candidate X2.

[0054] [Bolt hole type determination process] In the bolt hole type determination process, the processing information formation unit 42 sets the type of bolt hole 28 for each bolt hole candidate based on the positional relationship of the fitting 10.

[0055] The determination of the type of bolt hole 28 may be performed after the selection process. In the bolt hole type determination process, the processing information formation unit 42 sets the type of bolt hole 28 for each selected bolt hole 28 based on the positional relationship between the bolt hole 28 and the fitting 10.

[0056] Bolt holes 28 are divided into three types depending on whether they have a counterbore 29 to accommodate the bolt head. A first type bolt hole 28A is a hole with a counterbore 29 at the right end when viewed from the reference direction. A second type bolt hole 28B is a hole with a counterbore 29 at the left end when viewed from the reference direction. A third type bolt hole 28C is a hole without a counterbore 29 at either end.

[0057] The reference direction is set in advance. The reference direction is defined for each of the first subgroup and the second subgroup. In this embodiment, the reference direction of the first subgroup is the direction toward the AA cross section in FIG. 2. The reference direction of the second subgroup is the direction toward the BB cross section in FIG. 2.

[0058] In the case where bolt hole 28 has an open end on a surface on which fitting 10 is placed, that surface is not provided with countersink 29. In the case where bolt hole 28 has an open end on a surface on which fitting 10 is not placed, that surface is provided with countersink 29.

[0059] In the bolt hole type determination process, the processing information formation unit 42 determines the type of the bolt hole 28 based on the relationship with the fitting 10.

[0060] "Selection process" The selection process will be described with reference to Figures 11 and 12. The first direction shown in Figures 11 and 12 is the direction from the first side surface 2A to the third side surface 2C. The second direction shown in Figures 11 and 12 is the direction from the second side surface 2B to the fourth side surface 2D. In Figure 12, the circle surrounding the bolt hole 28 indicates the counterbore 29. The solid line counterbore 29 indicates the counterbore 29 on the front side surface of the wooden shaft 2 in the viewed direction when viewed from the first direction or the second direction. The dashed line counterbore 29 indicates the counterbore 29 on the back side surface of the wooden shaft 2 in the viewed direction when viewed from the first direction or the second direction.

[0061] In the selection process, the processing information formation unit 42 selects bolt holes 28 that satisfy predetermined conditions of the metal fitting 10 from the bolt hole candidates.

[0062] Specifically, in the selection process, processing information formation unit 42 selects bolt holes 28 from each of first bolt hole candidate X1 and second bolt hole candidate X2 so as to satisfy a first condition and a second condition. The first condition is that bolt holes 28 selected from first bolt hole candidate X1 and bolt holes 28 selected from second bolt hole candidate X2 do not interfere with each other. The second condition is that a fixing condition for metal fitting 10 is satisfied. The fixing condition for metal fitting 10 is that the number of bolt holes 28 satisfies the required number of bolts.

[0063] The processing information forming unit 42 executes a first pattern selection process. Specifically, the processing information forming unit 42 selects candidates for bolt holes 28 in the first bolt hole candidate X1 so as to satisfy the fixing conditions of the fitting 10. In one example, when the topmost one in the first fitting 11 is an invalid hole 28D, the processing information forming unit 42 selects every other bolt hole 28 from the first bolt hole candidate X1, excluding the topmost one, starting with the second hole from the top as the starting hole. Then, the processing information forming unit 42 determines whether or not the fixing conditions are satisfied for all fittings 10 in the first subgroup. Specifically, the processing information forming unit 42 determines that the fixing conditions are satisfied when the number of selected bolt holes 28 is equal to or greater than the number of bolts required for the fitting 10 in all fittings 10 in the first subgroup.

[0064] Next, the processing information formation unit 42 selects bolt holes 28 from the second bolt hole candidates X2 so that the bolt holes 28 selected from the first bolt hole candidates X1 and the bolt holes 28 selected from the second bolt hole candidates X2 do not interfere with each other. Specifically, the processing information formation unit 42 excludes bolt holes 28 at the same height as the bolt holes 28 selected from the first bolt hole candidates X1 from the second bolt hole candidates X2. Then, the processing information formation unit 42 selects the remaining bolt holes 28 remaining after the exclusion as bolt holes 28. Then, the processing information formation unit 42 determines whether or not the fixing condition is satisfied for all of the fittings 10 in the second subgroup. Specifically, the processing information formation unit 42 determines that the fixing condition is satisfied when the number of selected bolt holes 28 is equal to or greater than the number of bolts required for the fitting 10 for all of the fittings 10 in the second subgroup. If the fixing condition is satisfied, the processing information formation unit 42 completes the process.

[0065] If the fixed condition is not satisfied, the processing information forming unit 42 resets the bolt hole 28 selected from the first bolt hole candidate X1 and the bolt hole 28 selected from the second bolt hole candidate X2.

[0066] Then, the processing information formation unit 42 executes the second pattern selection process as follows. Specifically, the processing information formation unit 42 first selects bolt holes 28 from the second bolt hole candidates X2. The processing information formation unit 42 determines whether or not the fixing conditions are met for all of the fittings 10 in the second subgroup. Next, the processing information formation unit 42 selects bolt holes 28 from the first bolt hole candidates X1 so as not to interfere with bolt holes 28 from the second bolt hole candidates X2. The processing information formation unit 42 determines whether or not the fixing conditions are met for all of the fittings 10 in the first subgroup.

[0067] When the processing information forming unit 42 determines that the fixed condition is satisfied for all the metal fittings 10 in the second pattern selection process, the processing is completed. When the fixed condition is not satisfied for any one of the metal fittings 10 in the second pattern selection process, the processing information forming unit 42 changes the condition. For example, in the first pattern selection process, the processing information forming unit 42 sets the second metal fitting hole 10A from the top as the selection start hole, but in the next process, the processing information forming unit 42 sets the third metal fitting hole 10A from the top as the selection start hole. Then, the processing information forming unit 42 executes the first pattern selection process under the changed condition. When the fixed condition is not satisfied in the first pattern selection process, the processing information forming unit 42 executes the second pattern selection process. The processing information forming unit 42 selects a bolt hole 28 that satisfies the fixed condition by repeating the first pattern selection process, the second pattern selection process, and the change of the start hole. The maximum number of times MAX that the start hole can be changed is set in advance. If the fixed conditions cannot be met for one or several fittings 10 even after the start hole has been changed up to the maximum number of times MAX, the processing information forming unit 42 displays on the display unit 43 that the selection is not possible, and ends the process.

[0068] A process flow executed by the processing information forming system 40 will be described with reference to Fig. 13. The process flow is executed for each of the multiple wooden shafts 2 of the building.

[0069] In the processing flow, the value of NA indicates the ordinal number of the group of metal fittings 10. The initial value of NA is 0. When NA is 1, it indicates the first group. When NA is 2, it indicates the second group. NB indicates the ordinal number of the pattern selection process. The initial value of NB is 0. When NB is 1, it indicates the first pattern selection process. When NB is 2, it indicates the second pattern selection process. NC indicates the number of times the starting hole is changed. The initial value of NC is -1. When NC is 1, it indicates that the starting hole is changed once.

[0070] In a first step S1, the information acquisition unit 41 acquires the wooden shaft information, the metal fitting information, and the fixing position information for the wooden shaft 2 to be processed.

[0071] In a second step S2, the processing information forming unit 42 executes a grouping process on the wooden shaft 2 to be processed.

[0072] In a third step S3, the number of NA is increased by 1. When NA is 1, the processing target is the first group. When NA is 2, the processing target is the first group. That is, the process of selecting bolt holes 28 is executed for each group.

[0073] In the fourth step S4, the processing information forming unit 42 executes the hole candidate setting process as described above. In the fifth step S5, the number of NCs is increased by one.

[0074] In a sixth step S6, the processing information forming unit 42 sets a start hole according to NC. When NC is 0, the start hole is not changed. When NC is 1, the processing information forming unit 42 changes the position of the start hole to one position below.

[0075] In the seventh step S7, the number of NB is incremented by 1. When NB is 1, the execution of the first pattern selection process is prepared. When NB is 2, the execution of the second pattern selection process is prepared.

[0076] In an eighth step S8, the processing information forming unit 42 selects the bolt holes 28 by executing the processing prepared in the seventh step S7.

[0077] In a ninth step S9, the processing information formation unit 42 determines whether or not the number of selected bolt holes 28 for each fitting 10 satisfies the fixing condition. If all fittings 10 satisfy the fixing condition, it is determined that the fixing condition is satisfied. In this case, the processing information formation unit 42 executes the process of a twelfth step S12. If even one of the fittings 10 does not satisfy the fixing condition, it is determined that the fixing condition is not satisfied. In this case, the processing information formation unit 42 executes the process of the next tenth step S10.

[0078] In the tenth step S10, when NB is 2, the processing information forming unit 42 executes the process of the next eleventh step S11. When NB is not 2, the processing information forming unit 42 executes the process of the seventh step S7.

[0079] In an eleventh step S11, it is determined whether NC exceeds the maximum number MAX. If NC does not exceed the maximum number MAX, the processing information forming unit 42 executes the processing of a fifth step S5. At this time, the value of NC is increased by one in the fifth step S5, and the conditions of the start hole are changed. If NC exceeds the maximum number MAX, the processing information forming unit 42 executes the next twelfth step S12 and outputs to the display unit 43 a message indicating that a bolt hole 28 could not be selected in the group.

[0080] In a twelfth step S12, it is determined whether NA is the number of groups. If NC is the number of groups, the processing information forming unit 42 ends the process. At the end of the process, the bolt holes 28 are selected for each group set for the wooden shaft 2.

[0081] (Action of this embodiment) When a large number of fittings 10 are connected to the wooden shaft 2, the number of bolt holes 28 for fixing the fittings 10 increases. For this reason, it is difficult to set the bolt holes 28 so that the bolt holes 28 do not interfere with each other and the fixing conditions are satisfied. When bolt holes 28 are selected in order for each fitting 10 without grouping, if bolt holes 28 that interfere with each other are found during the selection process, the selection work may have to be redone.

[0082] According to the processing information forming system 40 of this embodiment, the processing information forming unit 42 executes a grouping process. In the grouping process, based on the hardware information and the fixed position information, the hardware 10 whose hole positions overlap in the height direction when the hardware 10 is placed on the wooden shaft 2 are grouped. By grouping the hardware 10, it is possible to select bolt holes 28 from a group of bolt holes 28 that may interfere with each other, and therefore it is possible to prevent overlooking bolt holes 28 that interfere with each other. This improves the work efficiency of selecting bolt holes 28.

[0083] In addition, the positions of the bolt holes 28 can be determined for each group. This reduces the need to reset the hole positions. In this way, the work efficiency in forming the processing data for the wooden shaft 2 can be improved.

[0084] (Effects of this embodiment) (1) In the processing information formation system 40, the processing information formation unit 42 executes a grouping process. In the grouping process, based on the fitting information and the fixed position information, when the fittings 10 are placed on the wooden shaft 2, the fittings 10 whose hole positions overlap in the height direction are grouped.

[0085] According to this configuration, since a grouping process is performed to group the metal fittings 10 whose hole positions overlap, the positions of the bolt holes 28 can be determined for each group. This reduces the need to reset the positions of the bolt holes 28. In this way, the work efficiency in forming the processing data for the wooden shaft 2 can be improved.

[0086] (2) In the grouping process, the processing information formation unit 42 classifies the grouped fittings 10 that are arranged on the first side surface 2A and the third side surface 2C into a first subgroup. In the grouped fittings 10, the processing information formation unit 42 classifies the grouped fittings 10 that are arranged on the second side surface 2B and the fourth side surface 2D into a second subgroup. Then, in the hole candidate setting process, a first bolt hole candidate X1 is set in the first subgroup, and a second bolt hole candidate X2 is set in the second subgroup.

[0087] According to this configuration, the first subgroup and the second subgroup are groups of fittings 10 that are located at opposite positions relative to the wooden shaft 2. Then, candidates for bolt holes 28 are set independently for each of the first subgroup and the second subgroup. This reduces the number of options when selecting bolt holes 28, improving calculation efficiency.

[0088] (3) In the grouping process, the processing information formation unit 42 creates groups by repeating the group association process for the fittings 10 in the order of arrangement of the fittings 10 in the height direction. In the group association process, if the position of any one of the fitting holes 10A of the fitting 10 that is the subject of the grouping process overlaps with the position of the fitting hole 10A of at least one fitting 10 that belonged to a group before the relevant fitting 10, the target fitting 10 is made to belong to the group.

[0089] This configuration makes it possible to prevent the fittings 10 that should be grouped from being removed from the group. In this manner, the fittings 10 can be appropriately grouped.

[0090] (4) In the bolt hole type determination process, the processing information formation unit 42 sets the type of bolt hole 28 for each of the bolt hole candidates or each of the selected bolt holes 28 based on the positional relationship of the fitting 10. According to this configuration, the type of bolt hole 28 can be set.

[0091] (5) In the hole candidate setting process, the processing information formation unit 42 selects bolt hole candidates based on the fastening hole information included in the fitting information. With this configuration, it is possible to select bolt hole candidates suitable for the fitting 10.

[0092] <Modification> The above embodiment is an example of a form that the processing information forming system 40 can take, and is not intended to limit the form. The processing information forming system 40 can take a form different from the form exemplified in the above embodiment. Examples of such a form include a form in which a part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0093] The technology disclosed herein may be configured as a program executed by a computer. The processing information forming program causes the computer to form hole formation information in the wooden shaft 2. The processing information forming program includes an information acquisition step and a processing information forming step. The information acquisition step causes the computer to acquire wooden shaft information, hardware information of the hardware 10 connected to the wooden shaft 2, and fixing position information indicating the fixing position of the hardware 10 relative to the wooden shaft 2. The machining information forming step causes the computer to execute a grouping process, a hole candidate setting process, and a selection process. In the grouping process, the computer groups the fittings 10 whose hole positions overlap in the height direction when the fittings 10 are placed on the wooden shaft 2 based on the fitting information and the fixing position information. The hole candidate setting process causes the computer to set bolt hole candidates for fastening the fittings 10 in the group based on the fitting information of each fitting 10 in the group. In the selection process, the computer is caused to select a bolt hole 28 that satisfies the fixing conditions of the metal fitting 10 from the bolt hole candidates.

[0094] According to this configuration, a grouping process is performed to group the metal fittings 10 whose hole positions overlap, so that the hole positions can be determined for each group. This reduces the need to reset the hole positions. In this way, the work efficiency in forming the processing data for the wooden shaft 2 can be improved.
