Unexamined-Japanese-Patent No. 2006-249697

  In the housing of the type described above, the manufacturing efficiency can be improved by collectively processing the building materials individually performed at the construction site in a factory. However, in order to automate the processing of building materials to realize improvement in manufacturing efficiency, there is still room for improvement in the configuration related to the processing.

  In addition, the said subject is not a thing which generate | occur | produces only in a floor structure, It is a subject which may generate | occur | produce similarly also in the other building structure (for example, ceiling structure) which combines a flame | frame and a facing.

  This invention is made in view of the said situation, and makes it a main purpose to provide the processing apparatus for building materials which can raise manufacturing efficiency suitably.

  Hereinafter, means etc. effective for solving the above-mentioned subject are explained, showing an effect etc. if needed. In the following, for ease of understanding, the corresponding configuration in the embodiment of the invention is appropriately shown in parentheses or the like, but it is not limited to the specific configuration shown in the parentheses or the like.

Means 1. When fixing facing materials (base material 21) made of different materials to a frame material (floor girder 12, floor girder 13) constituting a framework of a building, the communication holes communicating with the frame material and the surface material A building material processing apparatus (fixing apparatus 50) used when forming and processing any of the frame material and the self-tapping for the surface material,
A tool (drill 63) configured to be displaceable along an axis extending in the overlapping direction of the frame member and the face member and to be rotatable about the axis;
Drive control means (control device 54) for performing drive control of the tool;
The drive control means is a switching means for switching at least one of the rotational speed and the feed speed of the tool according to the change of the processing object when the processing is performed in a state where the frame member and the face member overlap. A processing apparatus for building materials characterized by having (a switching function in the control device 54).

  In the case of forming a building unit by combining a frame material and a face material, in a configuration that requires some processing on both, it is also possible to process the frame material and the face material alone, for example, and combine them after processing . However, when the processing steps are divided as described above, it is assumed that the preparation period and the like involved in the processing are likely to be bulky. This can be an obstacle to the improvement of manufacturing efficiency. On the other hand, as shown to this means 1, when it is set as the structure which processes frame material and a face material collectively, processing of each time is unnecessary and the said subject can be solved.

  However, in the case where materials are different between the facing material and the frame material, if processing is to be performed under the same conditions, unreasonableness may occur in securing the quality etc. of the building unit. In this respect, in the present means 1, when the object to be processed moves from one of the frame material and the face material to the other, it responds accordingly (that is, according to which of the frame material and the face material is to be processed). ) The speed conditions (rotational speed, feed speed) relating to processing are switched. As a result, when the frame material and the face material are collectively processed, it is possible to realize the improvement of the manufacturing efficiency described above while suppressing the deterioration of the quality.

Means 2. The frame material is made of a material of higher strength than the face material,
As a mode of drive control by the drive control means, a first drive control mode in which a rotational speed of the tool is set to a first rotational speed and a feed speed of the tool is set to a first feed speed, and rotation of the tool A second drive control mode is provided, which is set such that the second rotational speed is lower than the first rotational speed and the second feed speed is lower than the first feed speed. Yes,
The switching means performs the drive control in the first drive control mode when processing the surface material with the tool, and the second drive control mode when processing the frame material with the tool. The processing device for building materials according to the means 1, characterized in that the drive control mode is switched to perform the drive control.

  When the frame material is formed of a material of higher strength than the face material, the tool or frame material is processed by processing the frame material at the same rotational speed and feed rate as the face material which is relatively easy to process The load generated on the This causes a reduction in the durability of the processing apparatus (tool), and a reduction in the quality of the product such as deformation of the frame. On the other hand, if it is attempted to process the face material at a rotational speed and feed rate set according to the frame material, which is relatively difficult to process, the processing time of the face material is extended for a while, which hinders improvement of manufacturing efficiency. . Therefore, by switching the rotational speed and the feed speed to low speed / high speed according to the strength of the processing object, it is possible to preferably suppress the occurrence of the various inconveniences resulting from the improvement of the manufacturing efficiency.

  Means 3. Means 1 or 3, characterized in that it comprises reversing means for displacing the tool in the opposite direction to the feed direction before performing switching when switching the mode of drive control by the drive control means by the switching means. The processing device for building materials according to the means 2.

  When the mode of drive control changes, that is, when the object to be processed changes, chips generated in the object to be processed can be discharged by reversing the tool. Thereby, it is possible to suppress that chips generated in one processing object affect the other processing. Therefore, even in the case of collectively processing the frame material and the face material, it is possible to preferably suppress a decrease in processing accuracy and processing efficiency.

  In addition, in a processing apparatus of a type in which the tool is displaced between the standby position and the processing position, it is sufficient as long as chips can be discharged by inversion, and in the case where the tool is displaced by the reversing means There is no need to put it back.

Means 4. The frame material is made of metal and the facing is wooden,
As a mode of drive control by the drive control means, a first drive control mode in which a rotational speed of the tool is set to a first rotational speed and a feed speed of the tool is set to a first feed speed, and rotation of the tool A second drive control mode is provided, which is set such that the second rotational speed is lower than the first rotational speed and the second feed speed is lower than the first feed speed. Yes,
The switching means performs the drive control in the first drive control mode when processing the surface material with the tool, and the second drive control mode when processing the frame material with the tool. Is configured to switch the drive control mode so that the drive control is performed.
The reversing means performs the reversing when the mode of drive control is switched from the first drive control mode to the second drive control mode by the switching means, and the mode of drive control is changed by the switching means. When it switches from a 2nd drive control mode to a said 1st drive control mode, it becomes a structure which does not implement inversion by the said inversion means, The processing apparatus for building materials as described in the means 3 characterized by the above-mentioned.

  Although the halfway reversal function shown in the means 3 is advantageous in realizing quality improvement and the like, an increase in the frequency of its execution can be a factor that hinders improvement in manufacturing efficiency. Therefore, as shown in the above configuration, the processing of metal frame material which is relatively severe affects the processing by discharging chips generated when wood is processed before processing the metal frame material. Can be suppressed. On the other hand, since the processing conditions for wood are not so severe, the influence of chips generated when processing a metal frame is relatively small. Therefore, when switching from the second drive control mode to the first drive control mode, the configuration is made such that the above-mentioned reversal (discharge of chips) is not performed to improve manufacturing efficiency while enjoying the benefit of the quality improvement effect. Can contribute to

  For example, if the technical idea shown in the present means 4 is applied to a configuration in which the thickness of the face material is larger than the thickness of the frame material, the above effect can be suitably obtained.

  By the way, by configuring “in the case of reversing by the reversing means, the return speed at the time of returning to the processing position before reversing is faster than the feed speed at the time of processing”, the manufacturing efficiency is further reduced. It can be suitably suppressed.

Means 5. A floor unit (floor unit 10) constituting a floor structure portion of a building is constructed by the frame material and the facing material,
As a mode of drive control by the drive control means, a first drive control mode in which a rotational speed of the tool is set to a first rotational speed and a feed speed of the tool is set to a first feed speed, and rotation of the tool A second drive control mode is provided, which is set such that the second rotational speed is lower than the first rotational speed and the second feed speed is lower than the first feed speed. Yes,
In the drive control means, as the assumed position where the frame material is assumed to be present, a first assumed position and a second assumed position which is behind the first assumed position in the feeding direction of the tool are previously determined. It has been
When the tool passes the first assumed position and the second assumed position in the process of the tool being displaced from the standby position to the processing completion position, the switching means performs the first drive control mode. The processing apparatus for building materials according to any one of means 1 to 4, which is configured to switch from the control mode to the second drive control mode.

  As for the floor unit formed by combining the frame material and the facing material, the positional relationship between the frame and the facing material may be various according to the specification of the building. If the above-described drive control modes are individually set according to various positional relationships, not only the control pattern becomes complicated, but also the possibility of defects etc. being generated due to processing based on erroneous information or the like is high. Would be concerned.

  As for the floor unit, the face material is placed on the frame material, so the vertical relationship (processing order) between the frame material and the face material is unique, and the distance between the upper surface of the face material and the upper surface of the frame material depends on the specifications. Can change. Therefore, if the first drive control mode and the second drive control mode are alternately repeated, it is possible to cope with the difference in the positional relationship described above. For example, if the frame material exists at a relatively shallow position (first assumed position), the frame material can be processed in the first second drive control mode, and the relatively deep position (second assumed position (second assumed position) The frame material can be processed in the second drive control mode after the second time if the frame material is present in. Thereby, the difference of the distance mentioned above is permitted, and it becomes processable by the aspect of the same drive control. As described above, sharing (unifying) the operation of the processing apparatus is advantageous in suppressing the occurrence of the above-mentioned mistake. And since it becomes unnecessary to change a control mode each time according to a positional relationship, it can contribute also to the improvement of manufacturing efficiency as a result.

Means 6. The face material is fixed to the frame material without a base material, and a first fixing portion (for example, an end of the base material 21) fixed to the frame material via the base material (joint 22) And a second fixed portion (for example, the central portion of the base material 21),
As a mode of drive control by the drive control means, a first drive control mode in which a rotational speed of the tool is set to a first rotational speed and a feed speed of the tool is set to a first feed speed, and rotation of the tool A second drive control mode is provided, which is set to have a second rotational speed lower than the first rotational speed and a second rotational speed lower than the feed speed of the tool. Yes,
In the drive control means, the first assumed position where the frame material is assumed to be present at the two fixing portions, and the position behind the first expected position in the feeding direction of the tool, A second assumed position where the frame material is assumed to be present in the second fixed portion is determined in advance,
When the tool passes the first assumed position and the second assumed position in the process of the tool being displaced from the standby position to the processing completion position, the switching means performs the first drive control mode. The processing apparatus for building materials according to any one of means 1 to 5, wherein the apparatus is configured to switch from the control mode to the second drive control mode.

  According to the means 6, the mode of drive control switches from the first drive control mode to the second drive control mode at the first assumed position and the second assumed position. For this reason, if the frame material exists at a relatively shallow position (first assumed position), the frame material can be processed in the first second drive control mode, and the relatively deep position (second assumed position If the frame material exists at the position), the beam material can be processed in the second drive control mode for the second time. This makes it possible to process a plurality of types of positional relationships by similar drive control. Thus, unifying the movement of the tool is advantageous in suppressing the occurrence of the above-mentioned inconvenience. And since it becomes unnecessary to change the mode of drive control each time according to the said positional relationship, it can contribute also to the improvement of manufacturing efficiency as a result.

Means 7. The frame material has a plurality of large beams (floor large beams 12) and small beams (floor small beams 13) connecting the large beams.
The face material is fixed to the girder without the first fixing portion (end portion of the base material 21) fixed to the large beam via the joist (end 22) and the joist. And a second fixed portion (central portion of the base material 21),
The tool includes a first tool corresponding to the first fixed portion and a second tool corresponding to the second fixed portion, and the processing is simultaneously performed by the first tool and the second tool. It is
As a mode of drive control by the drive control means, a first drive control mode in which the rotational speeds of both tools are set to the first rotational speed and the feed speeds of both the tools become the first feed speed; A second drive control mode in which a second rotational speed at which the rotational speed of the tool is lower than the first rotational speed and a second rotational speed at which the feed speeds of the two tools are lower than the first feed speed Is provided,
In the drive control means, there are a first assumed position where the small beam is assumed to be present at the two fixed portions, and a position behind the first expected position in the feed direction of the tools. A second assumed position where the large beam is assumed to exist at the second fixed portion is determined in advance,
When the tools pass through the first assumed position and the second assumed position in the process of shifting both the tools from the standby position to the processing completion position, the switching means performs the drive control mode. (1) The processing apparatus for building materials according to any one of means 1 to 6, which is configured to switch from the drive control mode to the second drive control mode.

  As shown in the means 7, according to the configuration in which the plurality of fixing portions are collectively fixed by the plurality of tools, the processing time can be shortened as the configuration in which the respective fixing portions are fixed in order. Here, although it is possible to set the operation of both tools individually, with such a configuration, not only the control load increases but also the possibility of defects etc. being generated due to erroneous processing is high. Would be concerned. In addition, since the machining time depends on the most necessary place of the time, even if the movement of the tool is partially changed at other places, substantial shortening of the machining time can not be expected.

  Therefore, as shown in the present means 7, if the first drive control mode and the second drive control mode are alternately repeated in both the first fixed portion and the second fixed portion, for example, they are relatively shallow. If a small beam exists at the position (first assumed position), the small beam can be processed in the first second drive control mode, and the large beam exists at a relatively deep position (second assumed position) If so, the large beam can be processed in the second drive control mode for the second time. This makes it possible to process a plurality of types of positional relationships by similar drive control. Thus, unifying the movement of the tool is advantageous in suppressing the occurrence of the above-mentioned inconvenience. And since it becomes unnecessary to change the mode of drive control each time according to the said positional relationship, it can contribute also to the improvement of manufacturing efficiency as a result.

Means 8. A first floor unit, in which the frame material is constituted by a plurality of large beams (floor large beams 12) and small beams (floor small beams 13) connecting the large beams, and a plurality of large beams (floor large beams 12) and small beams connecting the large beams The processing device for building materials, wherein the frame material is constituted by (floor beam 13), and the distance from the lower surface of the large beam to the upper surface of the beam is applied to both the second floor unit larger than the first floor unit. There,
As a mode of drive control by the drive control means, a first drive control mode in which a rotational speed of the tool is set to a first rotational speed and a feed speed of the tool is set to a first feed speed, and rotation of the tool A second drive control mode is provided, which is set such that the second rotational speed is lower than the first rotational speed and the second feed speed is lower than the first feed speed. Yes,
In the drive control means, there are a first assumed position where the beam is assumed to be present in the second floor unit, and a position behind the first expected position in the feed direction of both tools And a second assumed position where the beam is assumed to be present in the first floor unit,
When the tool passes the first assumed position and the second assumed position in the process of the tool being displaced from the standby position to the processing completion position, the switching means performs the first drive control mode. The processing apparatus for building materials according to any one of means 1 to 7, which is configured to switch from the control mode to the second drive control mode.

  In the case of the floor that constitutes the first floor portion of a building, a heat insulating layer is often formed in the floor unit in order to achieve heat insulation inside and outside the room. On the other hand, the floor that constitutes the space between the second floor and so on has a lower demand for the heat insulation function compared to the floor that forms the first floor, and the heat insulation function can be given to the ceiling structure below the floor, In many cases, the heat insulation layer like the first floor part is not necessary. In the case where the heat insulating layer is formed on the first floor portion, joists disposed between the frame material (large beam and beam) and the floor material take up a part of the heat insulating layer. On the other hand, in the second floor part where the heat insulation function is not required, the joist is disposed above the girder so that the joist to the floor material is omitted. Under such circumstances, the positional relationship between the frame material (the beam) and the face material can be diversified. If it is attempted to switch the mode of drive control described above according to various positional relationships, it is feared that not only the control pattern becomes complicated but also the possibility of occurrence of defects due to erroneous processing is increased.

  Therefore, since the small beam exists at a relatively shallow position (the first assumed position) in the second floor unit, the small beam is processed in the second drive control mode for the first time, and the relative movement is relatively performed in the first floor unit. Since the small beam exists at the deep position (second assumed position), the small beam may be processed in the second drive control mode for the second time. This makes it possible to process a plurality of floor units having different positional relationships by the same drive control. As described above, if the configuration is compatible with both the first floor unit and the second floor unit by a series of operations, it becomes unnecessary to change the setting of the operation mode according to the type of floor unit, resulting in improvement of manufacturing efficiency. Can also contribute.

  An embodiment of the present invention will be described below based on the drawings. In this embodiment, the manufacturing process of a building unit (specifically, a floor structure portion) is embodied in a unitary building constructed by combining a plurality of building units. Since the construction of the building unit and the unitary building is well known, the description by the drawings will be omitted, but will be briefly described. The building unit has four columns at four corners, a ceiling girder connecting upper ends of the columns, and a floor girder connecting lower ends of the columns, and is formed in a rectangular parallelepiped shape as a whole. This building unit is manufactured at a unit manufacturing plant, and then transported to a building construction site by transport means such as a truck. And in a building construction site, a building unit is installed using installation means, such as a crane, and a pillar of adjacent building units is connected by a connection member (docking plate etc.) so that a building main body is constructed. It has become.

  Hereinafter, the floor structure portion of the building unit will be described with reference to FIG. 1, and then the flow of manufacturing the floor structure portion will be described. Fig.1 (a) is a top view which shows the structure of the floor-structure part of a building unit, FIG.1 (b) is the AA partial cross section figure of FIG. In addition, the floor structure part of the building unit which comprises the first floor part of a building is illustrated about FIG. 1, and illustration is abbreviate | omitted about the flooring material which forms a floor upper surface.

The floor girder 12 is connected in two directions orthogonal to each other with respect to the connection 11. The floor girder 12 is made of a channel steel having a U-shaped cross section, and the openings are arranged to face each other, that is, the grooves are directed to the inside of the unit. The floor girder 12 as a whole is disposed to form a horizontally long rectangular frame, and a plurality of floor beams are bridged between a pair of floor girder 12 on the long side of each floor girder 12. 13 are provided. A floor frame 14 is constructed by the floor cross beam 12 and the floor cross beam 13.

  Above the floor frame 14, a wooden base material 21 (specifically, a particle board) is laid side by side in the direction in which the floor beams 13 are arranged (in the direction of the girder). As shown in FIG. 1 (b), a wooden joist 22 intervenes between the floor frame 14 and the foundation material 21, and the floor frame 14 and foundation material 21 are fixed with the jot 22 interposed therebetween. ing. A heat insulating material 24 (specifically, urethane foam) is disposed between the joists 22, and a heat insulating layer composed of the joists 22 and the heat insulation 24 is formed between the base material 21 and the floor frame 14. This reduces the heat loss under the floor.

  The joists 22 are arranged along the floor girder 12 and the floor girder 13, and the screws 23 inserted from the base material 21 pass through the joists 22 and the floor frame 14 (floor girder 12 and the floor girder 13) Fixed to both beams). For example, the connection portion BP of the base materials 21A to 21C is located on the floor beam 13, and the base material 21 is fixed to the floor beam 13 by screws 23 on both sides of the connection portion BP. Lifting of the end of the is suppressed. A floor unit 10 as a floor structure portion is constructed by the floor frame 14 and the base material 21.

  Here, with reference to FIG. 2, the flow of the structure and assembly which concern on the assembly of the floor unit 10 in a factory is demonstrated. FIG. 2 (a) is a schematic view showing the flow of assembling the floor unit 10, and FIG. 2 (b) is a schematic view showing a construction related to the assembly of the floor unit 10. As shown in FIG.

  As shown in FIG. 2, in the manufacturing process of the floor unit 10, the floor frame 14 formed through the welding process and the painting process is conveyed to the floor assembling process. In the floor assembling process, a fixing device 50 for fixing the floor frame 14 and the base material 21 is installed. The fixing device 50 includes a table 51 on which the floor frame 14 (work) transported in the floor assembling process is placed, and a drilling device 52 and a screw tightening device 53 disposed above the table 51.

  The punching device 52 includes a movable base 61 and a slide mechanism 62 which slides the movable base 61 along the table 51. The slide mechanism 62 is connected to the control device 54, and the position of the movable base 61 is changed based on a command from the control device 54. The floor frame 14 conveyed to the floor assembling step is disposed on the table 51 such that the sliding direction of the movable base 61 defined by the sliding mechanism 62 matches the girder direction of the floor frame 14.

  The movable base 61 is provided with a plurality of drills 63, and a rotation drive unit 64 (inverter) and a feed drive unit 65 (servo) provided to correspond to each drill 63 individually. The rotation drive unit 64 and the feed drive unit 65 are connected to the control device 54, and each drill 63 can be operated individually.

  A plurality of drills 63 are arranged side by side in the direction (the end direction) intersecting the slide direction. Thereby, it is possible to collectively form the pilot holes for screwing at a plurality of fixing points in the end direction. The position of the drill 63 in the arrangement direction is adjustable. Thereby, the pitch of a fixed location can be changed partially.

  The arrangement area of the drill group 63 is longer than the length in the end direction of the floor frame 14, and the adjustment range of the part of the drill group 63 (located at both ends) corresponds to the floor girder 12 It is configured to include the position. As a result, it is possible to perform the formation of the pilot holes in parallel at both the fixed location for the floor girder 12 and the fixed location for the floor girder 13.

  The screw tightening device 53 includes a movable base 71 and a slide mechanism 72 that slides the movable base 71 along the table 51 (in the same direction as the movable base 61). The slide mechanism 72 is connected to the control device 54, and the position of the movable base 71 is changed based on a command from the control device 54.

  The movable base 71 includes a plurality of bits 73 to which screws 23 as a fixing tool are attached, and a rotation drive unit 74 (inverter) and a feed drive unit 75 (air cylinders provided corresponding to each bit 73 individually). And are arranged. The rotation drive unit 74 and the feed drive unit 75 are connected to the control device 54, and each bit 73 can be operated individually.

  When the period required for forming the pilot hole by the drilling device 52 and the period required for screwing the pilot hole by the screw fastening device 53 are compared, the former is longer than the latter. So, in this embodiment, the device for shortening the waiting time of the screw fastening device 53 and improving the manufacturing efficiency in an assembly process is performed. Specifically, in the screw tightening device 53, the bits 73 are arranged in one row, whereas in the drilling device 52, the drills 63 are arranged in a plurality of rows in the slide direction (in the present embodiment, Are arranged in two columns) and the distance between the columns can be changed. As a result, it is possible to perform the formation of pilot holes for a plurality of beams in parallel (simultaneously) in the girder direction. Thereby, the waiting period of the screw fastening device 53 is shortened.

  Here, the flow of assembling the floor unit 10 will be described with reference to FIG. After the floor frame 14 is transported from the previous process to the floor assembly process, the size information of the floor frame 14 is acquired in the size information reading process (S101). Specifically, the floor frame 14 is provided with a bar code 15 to which the size information (digit size and girth size) of the floor frame 14 is given, and this bar code is read by the reading device 55 attached to the control device 54 Do 15 readings. As a result, the size information of the floor frame 14 transported this time is grasped by the control device 54.

  The control device 54 stores standard fixed locations determined in accordance with the size of the floor frame 14, and provisionally sets standard fixed locations (standard patterns) corresponding to the current floor frame 14 based on the grasped size information. (S102). Then, information on the temporarily set standard fixed place is displayed on the touch panel 56 (more specifically, the display screen 81) attached to the control device 54 (S102). After that, the various building materials which constitute floor unit 10 will be in the state where it was combined through the joist arrangement process (S103), the heat insulating material arrangement process (S104), and the foundation material arrangement process (S105).

  In the subsequent individual instruction step (S106), the fixed location is changed according to the floor frame 14 carried in this time. In the floor assembly process shown in the present embodiment, assembly is performed for a plurality of floor units 10 having different sizes and specifications. Here, with reference to FIG. 3, the types of the various floor units 10 manufactured in the main floor assembling step will be supplementarily described. FIG. 3A is a schematic view showing a floor unit 10X corresponding to a bathroom, and FIG. 3B is a schematic view showing a floor unit 10Y corresponding to underfloor storage.

  In the floor unit 10X shown in FIG. 3 (a), a sanitary space consisting of a bathroom portion S1 in which the bath unit is incorporated, a dismantling portion S2 provided adjacent thereto, a bathroom portion S1 and a dismantling portion S2 A living room portion S3 provided side by side is provided. In the living room portion S3, a plurality of floor beams 13 are provided in a state of being bridged between a pair of floor beams 12 on the long side of the floor beams 12.

  The bathroom portion S1 and the dressing room portion S2 are divided by the receiving beam 31aX provided in a state of being bridged between the floor girder 12 on the short side and the floor girder 13. In the dressing room portion S2, a plurality of receiving beam 31bX are provided in a state of being bridged between the floor beam 12 and the receiving beam 31aX. The floor board 21D for the dressing room portion S2 is supported by the receiving beam 31bX and the like.

  In the bathroom portion S1, the floor girder 12 and the receiving beam 31aX on the long side are opposed to each other, and the portion sandwiched by the floor girder 12 and the receiving beam 31aX is the non-arrangement area of the beam (opening 34X ). Water supply piping and drainage piping are connected to the bus unit through the opening 34X. A mounting bracket 32X is attached to the floor beam 12 and the receiving beam 31aX, and the bus unit is supported by the mounting bracket 32X.

  The floor unit 10Y shown in FIG. 3B is provided with a storage portion S4 in which the storage unit is incorporated at the center thereof. In a portion corresponding to the storage portion S4, two receiving small beams 35aY are disposed so as to bridge over two floor small beams 13. The receiving beam 35bY is disposed to bridge the receiving beam 35aY, and the receiving unit is supported by the receiving beam 35bY. The portion surrounded by the receiving beams 35aY and 35bY is a non-arranged area (opening 38Y) of the beam, and the case portion of the storage unit protrudes downward through the opening 38Y.

  Thus, with regard to the floor frame 14X for a bathroom and the floor frame 14Y for under-floor storage shown in FIGS. 3 (a) and 3 (b), FIG. Although it corresponds with the floor frame 14 shown in (a), a point where the portion where the bus unit and the storage unit are installed is a non-arrangement area of the beam and the base material (a point where the opening is formed) The structure is different from that of the floor frame 14 shown in FIG. Further, in the floor units 10X and 10Y, the openings 34X and 38Y are non-arrangement areas of the base material 21, and the fixing locations by the screws 23 are omitted around the openings 34X and 38Y.

  The sizes and positions of the bathroom portion S1 and the storage portion S4 are changed according to the specification of the building.

  Referring back to FIG. 2 again, in the floor assembly process, the fixed position by the screw 23 is different depending on which of the floor units 10, 10X and 10Y has been transported. The fixed points defined by the standard pattern correspond to the floor unit 10. Therefore, when assembling the other floor units 10X and 10Y, it is necessary to change the fixed points. Therefore, in the floor assembly process, the fixed location in accordance with the actual product is changed in the individual instruction process (S106). Here, with reference to FIG. 3, an aspect of the fixed part change will be described. FIG. 3 is a schematic view showing the touch panel 56. As shown in FIG.

  The display screen 81 of the touch panel 56 is provided with an image display area IE for displaying an image imitating the floor frame 14. In the image display area IE, the shape and fixed position of the floor frame 14 as a standard are displayed based on the information read in the size information reading step (S101).

  The display screen 81 is provided with an operation menu display area ME, and in this area, a plurality of operation menus classified for each operation content by the operator are displayed. As this operation menu, "small beam position" for adding / deleting a small beam, "seam change" for changing the joint portion BP of the base material 21, and "post avoidance for avoiding a post" , “Aperture avoidance” for avoiding the aperture, and “standard” for returning to the standard.

  For example, if the joint portion BP of the base material 21 is designated by “seam change”, fixed places are set on both sides of the joint portion BP at the designation destination. In addition, when the avoidance range is specified by “avoid opening” or “post avoidance”, the fixed portion overlapping the avoidance range is deleted, and the position is the closest to the avoidance range and becomes the edge of the base material 21 The fixed point is added to the position.

  When the operator selects one of these operation menus, detailed parameters corresponding to the selected menu are displayed in the parameter display area PE. In FIG. 4, the parameters when “beam position” is selected are displayed.

  For example, even if the floor frame 14X carried in corresponds to a bathroom, first, as shown in FIG. 4A, an image showing a standard fixed place and a standard image imitating a floor frame are displayed. Thereafter, when the operator changes the fixed location in accordance with the floor frame 14X, the image imitating the floor frame and the image showing the fixed location are changed according to the operation result. This makes it easy to compare the actual product with the change result. Further, in the state in which the base material 21 is superimposed on the floor frame 14, visual confirmation of the floor frame 14 by the base material 21 may be difficult. In this respect, by displaying an image imitating the floor frame 14, the convenience of the operator is improved.

  After the instruction in the individual instruction process is completed and the confirmation operation is performed, the process proceeds to the drilling process (S107). In the drilling process, the controller 54 starts a drilling processing sequence. In this sequence, the determined fixed locations are grasped to determine the order of drilling. Thereafter, drive control of the drilling device 52 is performed, and a pilot hole for screwing is formed at the fixed location. At this time, drilling at a plurality of locations is performed in parallel by the plurality of drills 63 described above. Thereby, shortening of processing time is achieved. Further, in the present embodiment, in parallel with the drilling process by the drilling device 52, screw tightening by the screw tightening device 53 is performed. That is, improvement in manufacturing efficiency is achieved by performing screw tightening in order from that in which the pilot hole was formed.

  As described above, in the configuration in which the operator manually instructs to change the fixed location, although it is advantageous in that the response width to the specification change etc. can be expanded, the occurrence of defects due to an instruction error etc. It is feared that the probability is high. This is not preferable because it causes deterioration in the quality of the floor unit 10 and a reduction in the working efficiency in the post process. Therefore, in the control device 54, for example, when the above-described opening or the like is formed in the floor unit 10, a process of removing the periphery of the opening from the fixing location is performed. Specifically, the drilling device 52 and the screw tightening device 53 are provided with detection sensors 66 and 76 for detecting whether or not the base material 21 exists at a position corresponding to each drill 63 and each bit 73. When the processing sequence is executed, the presence or absence of the base material 21 is confirmed based on the detection information from the detection sensors 66 and 76. If it is determined that the base material 21 does not exist, drilling and screwing at that position are avoided. The occurrence of the above-mentioned inconvenience is suppressed by such a device.

  In the drilling process, in the state in which the floor frame 14 and the base material 21 are overlapped, the work process is simplified by forming the pilot holes communicating with both. Specifically, it is configured to collectively process the wood base material 21 and the joists 22 and the metal floor frame 14 together.

  A relatively fast first rotational speed and a relatively slow second rotational speed are set as the rotational speed of the drill 63, and a relatively fast first feed speed and a relatively high as the elevation speed (feed speed) of the drill 63. Is set to the slow second feed speed. The first range in which the drive control mode is defined so that the entire stroke from the standby position of the drill 63 to the processing completion position is the first rotational speed and the first feed speed, the second rotational speed and the second feed A mode of drive control is divided into a second range defined so as to be the speed. In the state where the floor unit 10 is disposed on the table 51, the base material 21 and the joists 22 are located in the first range, and the floor frame 14 (the floor girder 12 and the floor girder 13) is located in the second range It has become. That is, the processing conditions are switched according to the switching of the processing object. In addition, although the plate thickness is different between the floor girder 12 and the floor girder 13 in detail, the second range corresponds to the thickness of these plural types, and the pilot hole is formed in the floor girder 12 The operation mode is unified by the drill 63 and the drill 63 forming the pilot hole in the floor beam 13. Thereby, the control load in the control device 54 is reduced.

  Here, as to the floor unit 10, the specific structure is different between the one constituting the floor structure portion of the first floor in the building and the one constituting the floor structure portion above the second floor (between floors) in the building. Here, this difference will be described with reference to FIGS. 1 (b) and 5 (a). In the following description, the floor unit constituting the first floor portion is distinguished as “floor unit 10L”, and the floor unit constituting the second floor portion as “floor unit 10U”. FIG. 5A is a schematic view showing the floor unit 10U.

  As shown in FIG. 1 (b), a heat insulating layer is often formed on the floor unit 10L for heat insulation inside and outside of the floor that constitutes the first floor portion of the building. On the other hand, with regard to the floor that constitutes between the floors, such as the second floor part, there is less demand for the heat insulating function compared to the floor that constitutes the first floor part, and furthermore the heat insulating function can be added to the ceiling structure part below the floor In many cases, the heat insulation layer like the first floor part is not necessary. When the heat insulating layer is formed on the first floor portion, the joists 22 disposed between the floor frame 14L (the floor girder 12 and the floor girder 13L) and the base material 21 bear a part of the heat insulating layer. On the other hand, in the floor frame 14U for the second floor where the heat insulation function is unnecessary, the floor girder 13U is disposed so as to project above the floor girder 12 as shown in FIG. 5 (b). Thus, the joists 22 between the base material 21 and the floor girder 13U are omitted.

  Due to such circumstances, the distance from the upper surface of the base material 21 to the upper surfaces of the floor beams 13L and 13U is different between the floor frame 14L for the first floor and the floor frame 14U for the second floor (section Y and section Z reference). If it is attempted to switch the mode of drive control described above according to the type of floor frame 14L, 14U transported, not only the control pattern becomes complicated but also the possibility that defects etc. may occur due to erroneous processing is increased. And be concerned.

  Further, in the floor frame 14U for the second floor, the floor girder 12 is fixed to the base material 21 via the joists 22, whereas the joists 22 are omitted for the floor girder 13U. For this reason, when the fixed location concerning the floor girder 12 and the fixed location concerning the floor girder 13U are compared, the distance from the upper surface of the foundation 21 to the upper surface of the floor girder 13U and the top of the foundation 21 from the floor The distance to the upper surface of the girder 12 is different (see the section X and the section Z). When forming the pilot holes together with the floor girder 12 and the floor girder 13U by the floor frame 14U for the second floor, the setting of the drive control mode is changed according to the processing location as described above. There are concerns such as the occurrence of defects.

  In the present embodiment, one of the features is that the aspect of the drive control is unified so as to allow differences in the drilling target and the drilling position. Specifically, a first drive control mode in which drive control is performed so as to have a first rotational speed and a first feed speed, and a second drive that performs drive control in such a manner that a second rotational speed and a second feed speed are achieved. One of the features is that the control mode is repeated in a predetermined order. The flow of drilling will be described below with reference to the timing chart of FIG.

  When the fixing operation is performed in the individual instruction step, the drilling device 52 starts the drilling process in the subsequent drilling step. At timing t1 at which drilling is started, the drill 63 starts rotation at a first rotation speed which is a relatively high rotation speed, and starts lowering at a first feed speed which is a relatively high feed speed. The drill 63 penetrates the base material 21 at the timing of t2 when the first predetermined period has elapsed from the timing of t1. When the work this time is the floor unit 10U for the second floor, the drill 63 corresponding to the floor beam 13U reaches the upper surface of the floor beam 13U. At timing t2, the drill 63 is inverted and returns to the position before the standby position (above the base material 21). As a result, chips generated when forming the pilot hole in the base material 21 are discharged.

  The drill 63 is decelerated to the second rotation speed or the second feed speed at the timing of t4 at which the first predetermined period has elapsed since the start of the descent again at the timing of t3. When the work this time is the floor unit 10U for the second floor, the object to be processed is shifted to the metal floor beam 13U, and accordingly the drive control mode from the first drive control mode to the second drive control mode Will be switched to Here, when the work is the floor unit 10U, the drill 63 does not reach the floor cross beam 12 yet in the floor cross beam 12, and the jot 22 is the target of the drilling process. Similarly, even when the work is the floor unit 10L for the first floor, the joists 22 are to be drilled. However, for the material to be processed, since the processing conditions are not severe metallicity but wooden, deterioration in processing quality caused by a decrease in rotational speed of the drill 63 and the like is suppressed.

  The drive control mode is switched to the first drive control mode again at the timing of t5 when the second predetermined period has elapsed since the drive control mode was switched to the second drive control mode. Thus, the rotational speed of the drill 63 becomes the first rotational speed, and the feed rate becomes the first feed rate. If the processing location corresponds to the floor girder 12 in the floor unit 10L for the first floor or the floor unit 10L for the second floor, the processing target shifts to the joist 22 and the pilot hole is formed in the joist 22 . On the other hand, when the processing location is a portion corresponding to the floor beam 13U in the floor unit 10U for the second floor, the processing target has already been completed, and the drill 63 will be idled. However, since the operation area (air gap) of the drill 63 is secured below the upper surface of the floor beam 13U, interference with the tip portion of the drill 63 is avoided. In addition, since the plate thickness of the floor girder 13U is sufficiently small compared to the thickness of the base material 21 and the amount of chips does not prevent the subsequent processing, the above-described inversion does not occur at the timing of t5.

  The drill 63 penetrates the joist 22 at the timing of t6 when the third predetermined period has elapsed from the timing of t5. When the processing location corresponds to the floor girder 12 and the floor girder 13L of the floor unit 10L for the first floor, the drill 63 reaches the upper surfaces of the floor girder 12 and the floor girder 13L. When the processing location corresponds to the floor girder 12 of the floor unit 10U for the second floor, the drill 63 reaches the upper surface of the floor girder 12. At the timing of t6, the drill 63 is inverted and returns to the position before the standby position (above the base material 21). As a result, chips generated when forming the pilot holes in the joists 22 are discharged.

  The drill 63 is decelerated to the second rotation speed or the second feeding speed at the timing of t8 when the fourth predetermined period has elapsed since the start of the descent again at the timing of t7. When the processing location corresponds to the floor girder 12 of the floor unit 10 L for the first floor and the floor girder 12 of the floor gutter 13 L or the floor unit 10 U for the second floor, the processing object is the metal girder 12 In order to move to the floor girder 13L, the mode of drive control is switched from the first drive control mode to the second drive control mode.

  At the timing of t9 when the fifth predetermined period has elapsed from the timing of t8, a pilot hole is formed in the floor girder 12 and the floor girder 13L to be processed, and the pilot hole penetrates the base material 21 and the floor frame 14 The formation is complete. After that, the drill 63 is inverted to start returning to the standby position, and after returning to the standby position at timing of t10, the rotation is stopped.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  The fixing point between the base material 21 and the floor frame 14 depends on the size of the frame material and the like. Therefore, by setting the standard fixed place based on the size information of the floor frame 14, it is not necessary to individually indicate all the fixed places. By making it possible to change the standard fixing points set in this way according to the shapes and combinations of the actual base material 21 and the floor frame 14, it is possible to realize diversification of the product to be manufactured and to manufacture based on it. It is possible to suppress a drop in efficiency (work efficiency).

  In particular, in the case where the floor frame 14 is configured by the floor girder 12 and the floor girder 13, the arrangement of the floor girder 13 depends on the length of the floor girder 12 or the like. Therefore, by setting the standard fixing points according to the length of the floor girder 12, even if it is necessary to make a subsequent correction, the correction can be made slight.

  The arrangement of the floor beams 13 may be changed based on the specifications of the building. For example, when a building unit such as a bus unit or storage under the floor is provided, some floor beams are removed or added for reinforcement around the location to avoid interference with the building unit. To Therefore, as shown in the present embodiment, by making it possible to change the fixed location based on the arrangement of the floor beam 13, it becomes easy to cope with various specifications, while realizing diversification of products to be manufactured. The above-described effect of suppressing the decrease in manufacturing efficiency (work efficiency) resulting therefrom can be suitably exhibited.

  For example, when a building unit such as a bus unit or under floor storage is provided, an opening may be formed in the frame member and the face member to avoid interference with the building unit. Therefore, even if the presence or absence of the opening is not specified at the time of initial setting, the fixing location related to the opening can be deleted by changing the fixing location, thereby making it easy to cope with various specifications.

  As described above, in the configuration in which a part of fixed parts is deleted from the standard setting part, the degree of freedom of correspondence for each specification can be increased, but there is a possibility that the quality may be deteriorated due to an operation error. For example, although the influence on the post-process is relatively small when the fixed part is added erroneously, the need for rework becomes high when the fixed part is added erroneously and the influence on the post-process is relatively It is assumed to be large. Therefore, when the face material can not be detected, the occurrence of the above-mentioned inconvenience can be suitably suppressed by adopting a configuration in which the drilling process and the screw tightening are not performed even if it is set as a fixed place. .

  The combination pattern of the base material 21 varies depending on the specification of the building, and a plurality of combination patterns may exist even if the size of the floor frame 14 is the same. Therefore, as described in the present embodiment, if it is possible to change the fixing location in accordance with the connecting portion BP, it is easy to cope with various specifications. Thereby, the said effect can be exhibited suitably.

  About the floor girder 12 which comprises a building frame, the pillar which similarly comprises a building frame is connected to the both ends. Here, depending on the specifications of the building, it is possible that the strength of the building frame can not be sufficiently secured by the pillars alone. In such a case, the strength can be secured by arranging intermediate members such as posts between the pillars. When the intermediate member extends in the vertical direction, the base material 21 is formed with a notch or the like for avoiding interference with the intermediate member. In such a configuration, floating of the base material 21 is likely to occur around the intermediate member. Therefore, differences in specifications can be suitably tolerated by making it possible to change the fixing point around the intermediate member.

  When the floor frame 14 and the base material 21 are combined to form the floor unit 10, for example, the floor frame 14 and the base material 21 may be separately processed alone and combined after processing. It is possible. However, when the processing steps are divided as described above, it is assumed that the preparation period and the like involved in the processing are likely to be bulky. This can be an obstacle to the improvement of manufacturing efficiency. On the other hand, if it is set as the structure which processes the floor frame 14 and the base material 21 collectively as shown in this Embodiment, processing of each time is unnecessary, and the said subject is solvable.

  However, in the case where the floor frame 14 and the base material 21 (base 22) are different in material, if processing is to be performed under the same conditions, unreasonableness may occur in securing processing quality. In this respect, when the object to be processed is moved from one of the floor frame 14 and the base material 21 (the joists 22) to the other, the speed conditions (rotational speed, feed speed) relating to the processing are switched accordingly. As a result, when the floor frame 14 and the base material 21 (the joists 22) of different materials are collectively processed, it is possible to realize the improvement of the manufacturing efficiency described above while suppressing the deterioration of the quality.

  When the floor frame 14 has higher strength than the base material 21 (post 22), the floor frame 14 is processed at the same rotational speed and feed rate as the base material 21 (post 22) which is relatively easy to process. As a result, the load generated on the tool and the floor frame 14 is increased. This causes a reduction in the durability of the processing apparatus (tool), and a reduction in the quality of the product such as deformation of the floor frame 14. On the other hand, if it is going to process base material 21 (base 22) at the rotational speed and feed speed set according to floor frame 14 which is relatively difficult to process, the processing time of base material 21 (base 22) is It is an obstacle to the improvement of manufacturing efficiency. Therefore, by switching the rotational speed and the feed speed to low speed / high speed according to the strength of the processing object, it is possible to preferably suppress the occurrence of the various inconveniences resulting from the improvement of the manufacturing efficiency.

  When the mode of drive control changes, that is, when the object to be processed changes, chips generated in the object to be processed can be discharged by reversing the tool. Thereby, it is possible to suppress that chips generated in one processing object affect the other processing. Therefore, even in the case of collectively processing the frame material and the face material, it is possible to preferably suppress a decrease in processing accuracy and processing efficiency.

  Although the midway inversion function described above is advantageous for realizing quality improvement and the like, the increase in the frequency of its execution can be a factor that hinders the improvement of manufacturing efficiency. Therefore, as described in the above configuration, the processing of the relatively severe floor frame 14 is affected by discharging the chips generated when processing the wood before the metallic floor frame 14 is processed. Can be suppressed. On the other hand, with regard to wood, since the processing conditions are not so severe, the influence of chips generated when processing the metal floor frame 14 is relatively small. Therefore, when switching from the second drive control mode to the first drive control mode, the configuration is made such that the above-mentioned reversal (discharge of chips) is not performed to improve manufacturing efficiency while enjoying the benefit of the quality improvement effect. Can contribute to

  In the case of the floor that constitutes the first floor portion of a building, a heat insulating layer is often formed in the floor unit in order to achieve heat insulation inside and outside the room. On the other hand, the floor that constitutes the space between the second floor and so on has a lower demand for the heat insulation function compared to the floor that forms the first floor, and the heat insulation function can be given to the ceiling structure below the floor, In many cases, the heat insulation layer like the first floor part is not necessary. When the heat insulating layer is formed on the first floor portion, the joists 22 disposed between the floor girder 12 and the floor girder 13 and the base material 21 take up a part of the heat insulation layer. On the other hand, in the second floor part where the heat insulation function is not required, the floor beam 13 is disposed above the floor beam 12 so that the joist between the base material 21 is omitted. . Due to such circumstances, the positional relationship between the floor beam 13 and the base material 21 can be diversified. If it is attempted to switch the mode of drive control described above according to various positional relationships, it is feared that not only the control pattern becomes complicated but also the possibility of occurrence of defects due to erroneous processing is increased.

  Since the foundation material 21 is disposed on the floor frame 14 in the floor unit 10 in the first place, the vertical relationship between the floor frame 14 and the foundation material 21 is unique. Therefore, if the first drive control mode and the second drive control mode are alternately repeated, the above-described positional relationship can be obtained without individually setting the operation mode of the processing apparatus according to the type of floor unit 10. Differences can be tolerated. Thus, unifying the operation of the processing apparatus is advantageous in suppressing the occurrence of the above-mentioned inconvenience. And since the setting change of the operation mode according to the kind of floor unit 10 becomes unnecessary, it can contribute also to the improvement of manufacturing efficiency as a result.

  According to the configuration in which a plurality of processing locations are processed together by a plurality of drills 63, shortening of processing time can be realized as a configuration in which each processing location is processed in order. Although it is possible to set the operation of each drill 63 individually, in such a configuration, not only the control load increases, but there is a concern that the possibility of occurrence of defects due to erroneous processing is high. Be done. In addition, since the processing time depends on the most necessary place of the time, even if the movement of the drill 63 is partially changed at other places, substantial reduction of the processing time can not be expected.

  Therefore, as shown in the present embodiment, if the first drive control mode and the second drive control mode are repeated in the same manner at a plurality of processing points, a plurality of types of combinations are performed by the same drive control. It becomes possible to process. Thus, unifying the movement of the tool is advantageous in suppressing the occurrence of the above-mentioned inconvenience. And since it becomes unnecessary to change the mode of drive control each time according to the said positional relationship, it can contribute also to the improvement of manufacturing efficiency as a result.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, the following alternative configurations may be applied individually to the configurations in the above-described embodiment, or may be applied in combination with each other.

  (1) In the above embodiment, the bar code 15 disposed on the floor frame 14 is configured to be provided with girder dimensions and end dimensions (corresponding to "correspondence information") of the floor frame 14, and the control device 54 The outer shape of the frame 14 is grasped. However, the information given to the barcode 15 is not limited to this. For example, the information on the number and the position of the floor beams 13 may be provided, or the information on the combination with the base material 21 may be provided.

  However, when the diversity of the floor unit 10 is taken into consideration, the load on information management increases as the amount of information to be provided increases. In addition, as the dependence on the information given to the bar code 15 becomes stronger, there is a concern that the degree of freedom in responding to a specification change etc. is reduced. In view of such circumstances, a standard fixed place is set based on the minimum information acquired as described in the above embodiment, and the standard fixed place is changed according to the real thing. preferable. Thereby, it is possible to preferably realize the reduction of the load related to the information management and the improvement of the degree of freedom.

  (2) In the above embodiment, the standard fixed place set based on the information from the reading device 55 (corresponding to the "information acquisition means") is changed based on the manual operation of the worker. This may be changed, and the control device 54 may be configured to uniquely perform the changing process of the fixed portion based on the information from various detection means such as the opening detection sensor and the connection portion detection sensor.

  (3) Although the above-mentioned embodiment illustrated about composition which arranges joists 22 so that floor girder 13 which constitutes "frame material" may be arranged, it is not limited to this. The joists 22 may be disposed so as to intersect the floor beam 13. However, in such a configuration, there is a possibility that the floor girder 13 and the base material 21 can not be fixed well if the joist 22 is displaced in the direction in which the floor girder 13 extends (the end direction). Increase. Therefore, it is preferable to arrange the joists 22 along the floor beams 13 in the configuration in which the drills 63 are arranged in the end-to-end direction.

  (4) In the above embodiment, the floor frame 14 and an image (pseudo image) imitating the fixed part are displayed on the display screen 81 constituting the "display device", but at least the operator grasps the fixed part As long as possible information is displayed, it is also possible to arbitrarily change the specific display mode. However, in the state where the foundation material 21 is disposed on the floor frame 14, it may be difficult to visually check the position and the like of the floor girder 13. Therefore, the convenience of the operator can be improved by displaying a pseudo image that visually imagines the floor frame 14 as described above.

  In the above embodiment, although the configuration of the pseudo image of the floor frame 14 is also changed according to the change of the fixed place, the present invention is not limited to this. Only the display of the fixed place is changed. Configuration is also possible.

  (5) In the above embodiment, when the floor frame 14 is transported to the floor assembly process, reading of the bar code 15 and display of the standard fixing location are performed before the placement of the base material 21 is performed. It is not limited to this order. It is also possible to adopt a configuration in which reading of the bar code 15 and display of a standard fixed position are performed after the placement of the base material 21 is performed.

  (6) In the above embodiment, the drilling device 52 for forming the pilot hole 25 so as to straddle the floor frame 14 having the floor girder 12 and the floor girder 13 and the base material 21 and the pilot hole 25 are inserted. Although the screw fastening device 53 for fixing the floor frame 14 and the base material 21 with the screws 23 is used in combination, the present invention is not limited to this. For example, in the case where the floor frame 14 and the base material 21 are fixed by a self-tapping screw, the drilling device 52 can be omitted.

  In this case, the rotational speed and the feed speed of the screw tightening device 53 may be switched according to the arrival position of the screw 23 (the object to be processed). For example, when the base material 21 as the “face material” is a target of tapping, the rotation speed of the bit 73 is set to the first rotation speed and the feed speed as the first feed speed, and the floor girder as the “frame material” If the rotation speed of the bit 73 is lower than the first rotation speed and the feed speed is lower than the first feed speed, the second feed speed is lower than the first feed speed. It is good to make it switch so that it may become.

  (7) In the above embodiment, the floor frame and the base material 21 constituting the floor unit 10 are fixed using the fixing device 50, but the ceiling frame and the ceiling panel are fixed using the fixing device 50. Configuration is also possible. Moreover, it is also possible to set it as the structure which fixes a wall to the flame | frame etc. of a building unit using the fixing device 50. FIG.

  (8) In the drive control of the hole drilling apparatus 52, the first drive control mode → the second drive control mode is repeated. However, the combination pattern of the floor frame 14 and the base material 21 to be processed is repeated for the number of repetitions. It is good to set according to the number. For example, when three patterns of distances from the upper surface of the base material 21 to the floor frame 14 exist, it is preferable to repeat switching of the first drive control mode → the second drive control mode three times.

  (9) In the above embodiment, when the drive control mode of the drilling device 52 is switched from the first drive control mode to the second drive control mode, the drill 63 is temporarily returned in the direction opposite to the feed direction (upward) The chip is discharged (a sweeping operation is performed), but the present invention is not limited to this. Such sweeping operation may be omitted.

  Further, the sweeping operation may be performed when switching from the second drive control mode to the first drive control mode. However, in order to realize security of quality and improvement of manufacturing efficiency in consideration of severe processing conditions and the generation of chips, in the combination of the floor frame 14 and the base material 21 shown in the above embodiment, Preferably, the sweeping operation is performed when switching from the first drive control mode to the second drive control mode.

  (10) In the above embodiment, the control device 54 is configured to store in advance the switching timing from the first drive control mode to the second drive control mode. However, the present invention is not limited to this. For example, the change of the object to be processed may be determined according to the load applied to the drill 63, and the mode of the drive control may be switched according to the determination result.

  (11) In the above embodiment, the number of rows (two rows) of the drills 63 of the drilling device 52 is set larger than the number of rows (one row) of the bits 73 of the screw tightening device 53. The number of columns of bits 73 may be arbitrarily changed. However, in consideration of the fact that the time required for attaching the screw 23 is longer than the time required for forming the pilot hole 25, the number of rows of the drills 63 is made larger than the number of rows of the bits 73 to simultaneously make a plurality of rows. It is preferable that the pilot holes 25 be formed.
