It is comprised so that a laser can be irradiated to a position.

Next, each function of the building production system which concerns on embodiment of this invention provided with the above-mentioned structure is demonstrated.
(1) Existing building survey support function First, existing building drawings (completed drawings, etc.) and information on existing parts of other buildings are placed in a three-dimensional space, and newly acquired measurement data and photo data are added. The “existing building survey support function” that centrally manages various building data, such as point cloud data of 3D models, will be described. In addition, the information regarding the existing part of the building includes, for example, a confirmation application duplicate, an inspected document, a building standard law related document, a completed drawing, a construction drawing, a specification, a building construction standard specification (JASS), a manufacturer specification, Includes performance charts, warranty cards, catalogs, inspection sheets, construction photographs such as bar arrangement photographs, facility management data, etc.

  When the digitized data of the existing part acquired by scanning an existing drawing of the building with a scanner (not shown) is taken into the memory 22 of the computer 20 by a predetermined operation from the input device 25, the CPU 21 receives the CAD data fetching means 31. And converting the digitized data of the existing part into three-dimensional CAD data. The CAD data is stored in the storage device 23 after the position is adjusted according to the scale and the surface direction designated by the operation from the input device 25.

  The three-dimensional laser scanner 10 is installed in an existing part of the building, irradiates the existing frame or equipment with laser light, acquires and captures point cloud data of the existing part of the building, and CAD data. And The CAD data is stored in the storage device 23 of the computer 20 by a predetermined operation from the input device 25.

  In addition, by a predetermined operation from the input device 25, an attribute is given in advance to a frame such as an existing column, beam, or floor slab of the building, and the range, height, depth, or the like of the frame is set. The CPU 21 functions as a housing creation means 32, creates a solid model of the housing, and incorporates the solid model into the CAD data fetched by the CAD data fetching means 31.

  When character data such as dimensions and comments obtained by measurement by the three-dimensional laser scanner 10 is input by a predetermined operation from the input device 25, the CPU 21 functions as the character data capturing means 33, and Character data is linked to each member such as a frame or equipment of an existing part of the building on the CAD data fetched by the CAD data fetching means 31.

Further, when image data such as a photograph of an existing part of the building and various data such as the existing drawing are captured into the memory 22 by a predetermined operation from the input device 25, the CPU 21 functions as an image data capturing unit 34, The image data and various data are linked to each member such as a frame or equipment of an existing part of the building on the CAD data fetched by the CAD data fetching means 31. Thus, for example, when the arrow displayed on the display 24 is clicked by the input device 25, the image data and various data related to the member indicated by the arrow are displayed on the display 24 together.
(2) Design support function Next, based on the 3D polygon model of the frame created from the point cloud data obtained by 3D laser scanner measurement, the interior design such as partition walls and ceiling is designed by 3D CAD. Support function "will be described. In the following description, a dry partition wall will be described as an example.

  If a line segment is specified by clicking two specific points by the input device 25 in a state where a plan view of the existing part of the three-dimensional CAD building is displayed on the display 24, the CPU 21 generates the face print generating means 35. The cut surface surrounded by the polygons among the vertical planes including the line segment from the three-dimensional polygon model 41 (see FIG. 4) of the existing part of the casing is shown as a region that attaches the partition wall Cut out as 46. Thereby, for example, partition marks 46 of the shape along the concavo-convex part of the polygon model of the frame such as the beam 42, the wall 43, the floor slab 44, and the ceiling slab 45 are automatically generated as shown in FIG. The mask 46 is stored in the storage device 23 after being assigned an ID number. The ID number of this mask 46 is inherited as an attribute of each member created based on the mask 46, and is used as a member count and construction position information to be described later, as well as when packing or carrying in a member. Is done.

  Next, in the state where the elevation of the existing part of the three-dimensional CAD building is displayed on the display 24, a selection from the input device 25 allows the user to select from the tattoos stored in the storage device 23. When the specification of the partition wall (for example, the thickness of the shaft assembly member, the clearance dimension, etc.) is specified for the specified print 46, when the two points of the start point S and the end point E are clicked, the CPU 21 The runner 47 is extracted from the member objects that function as the member object arranging means 36 and are registered in advance in the library of the storage device 23, and the starting point S and the end point E are the end points. The runner 47 is arranged after adjusting to the dimensions.

  Further, as shown in FIG. 5, when the upper and lower runners 47 are designated from the input device 25 and one predetermined arrangement position P is designated, the CPU 21 functions as the member object arrangement means 36. The stud 48 is extracted as a shaft assembly member from the member objects registered in advance in the library of the storage device 23, adjusted to a dimension that allows the upper and lower runners 47 to be connected at the predetermined arrangement position P, and then the stud 48. Are arranged in a vertical posture.

Furthermore, as described above, the specification of the partition wall board 49 (see FIG. 8) (for example, double-sided / single-sided, one-piece pasted / 2) with respect to the selected mask 46 by a predetermined operation from the input device 25. When a sheet is pasted, board type, board up / down / left / right orientation, board division pitch, etc., the CPU 21 functions as member object placement means 36, and the outer peripheral shape of the board 49 matches the shape of the ink brush 46. Thus, the board 49 is automatically allocated and arranged on the shaft assembly member.
(3) Member Data List (Cut List) Creation Function Next, a “member data list (cut list) creation function” for automatically creating a list of members arranged in the design support function will be described.

  When a predetermined operation is performed from the input device 25, the CPU 21 functions as the member data list creation means 37, and extracts the attribute, shape and dimension information of the newly placed member object to be constructed from the library of the storage device 23, A member object data list is created together with the machining dimensions of each member object, and this member object data list is stored in the storage device 25. At that time, the member arranged in accordance with the tattoo as described above can be a data list of the member associated with the ID number of the tattoo, It is also possible to create a data list whose elements are members designated on CAD.

  Thereafter, the data list of the member object is sent to the member factory 30 together with the CAD data. In the member data list, basic data items include, for example, the ID number of the tattoo, the member ID number automatically assigned on the CAD, the path name of the drawing file in which the member is shown, and the member. Work file name that is the drawing file name, reference file name that is the file name that is referenced by the drawing file that shows the part, part type, part name, part registration date, order date, delivery date Various data such as the installation date are stored, and these data can be output in an Excel format (CSV format or the like).

  In the member factory 30, each member is pre-cut or pre-fabricated and processed by an NC machine tool or the like based on the processing dimension list of the member object, and then an electronic tag (RFID tag) 52 is attached to the processed member 51. It is attached. An ID unique to the member object is written on the electronic tag 52, and this ID is associated with the ID number of the member 51.

As a method of associating the ID of the electronic tag 52 with the ID number of the member 51, for example, a method of adding the ID of the electronic tag 52 to the member data list (cut list) and associating it on the computer 20 side, There is a method of writing the ID of the corresponding member 51 to the electronic tag 52 after pasting the 52 on the member 51.
(4) Member positioning function Next, the electronic tag reader and the three-dimensional CAD cooperate to search for a member object corresponding to the ID written on the electronic tag 52 from the storage device 23 together with its construction position information, and automatically indicate the position. The “member positioning function” output to the device 40 will be described.

  When the member 51 is conveyed to the existing part of the building that is the construction site, the ID is recognized by the RFID reader 53 that is an electronic tag reader, and the information is transmitted to the computer 20, the CPU 21 outputs the member construction position output means. 29, and by recording the date in the delivery date column of the member 51 in the member data list, the fact that this member 51 has been delivered is recorded in the storage device 23, and at the same time, it corresponds to the ID on the CAD The member 51 is highlighted.

  At this time, when there are a plurality of members 51 of the same type and the same size, the member construction position output means 29 calculates the work efficiency from the members 51 stored in the member data list (cut list) in advance. In order to select an optimal member in consideration, all members of the same type and the same size as the member 51 corresponding to the ID read by the RFID reader 53 are recognized. The member construction position output means 29 has the same type and the same processing size as the member object corresponding to the ID read by the RFID reader 53 as a mode when the operator selects a specific member from among the members 51. A manual selection mode in which all the member objects are highlighted on the three-dimensional CAD and a member object corresponding to the ID read by the RFID reader 53 are designated in advance from among all the member objects of the same type and the same processing size. All the members of the same type and the same processing size as the member object corresponding to the ID read by the RFID reader 53 and the direction fixing mode in which the member objects are selected in order according to the applied construction direction and highlighted on the three-dimensional CAD Member object constructed immediately before from among the objects Closest members object to be construction in a position selected and is configured so as to arbitrarily select three modes of the automatic selection mode, to highlight on the three-dimensional CAD to.

  Further, the member construction position output means 29 reads construction position information of the member 51 from the CAD data stored in the recording device 23 based on the ID, and outputs position data of a point indicated by the automatic position pointing device 40. As the indication points of the members, the optimum indication points are defined in advance depending on the type, application, and mounting method of each member 51 and stored in the storage device 23. The three-dimensional coordinates of the indication point are extracted and output according to the position and orientation of each member 51 arranged at the position.

  As an example, assuming that the member 51 to be newly constructed is a dry partition wall, the dry partition wall includes a runner 47 attached to the floor surface and the ceiling surface, a stud 48 disposed on the runner 47 at equal intervals, and a runner 47. And a gypsum board 49 affixed to the front surface side of the stud 48.

  In the runner 47, as shown in FIG. 6, the center points of both end portions are defined as indicated points a. Further, considering that the studs 48 are installed on the runner 47 at predetermined intervals, as shown in FIG. 7, the side surface of the runner 47 or the floor surface beside the runner 47 is defined as the indication point b. The Further, in consideration of the fact that the gypsum board 49 is allocated so that the stud 48 becomes the joint of the board 49, as shown in FIG. 8, the corner of the board 49 is defined as the indication point c.

  As another example, assuming that the newly-constructed member 51 is an equipment member, equipment such as a refrigerator, a boiler, and a pump is generally installed on a machine foundation with bolts or the like. Bolt position is defined as the indicating point. On the other hand, equipment such as small equipment and pipes 54 and ducts 55 are attached to the building frame and interior materials by dedicated support members, mounts, etc., so the position of the members themselves is a point on the space and directly by the laser. It is difficult to point to that position. Therefore, an installation member (an anchor bolt or the like) of the equipment member installed by the support member, such as a pipe or a duct, is defined as an instruction point with respect to the support member housing or the like.

  For example, as shown in FIGS. 9 and 10, when the pipe 54 and the duct 55 are installed from the ceiling slab by the lifting tool 56, the position of the anchor bolt for the lifting tool is defined as the indication point (e in FIG. 9). And see f in FIG. In addition, when the pipe 54 and the duct 55 are mounted and fixed on the support frame installed on the floor, the anchor position on the floor surface of the frame is defined as the indication point (not shown). That is, the construction position information in the case where the newly constructed member 51 is an equipment member is defined as “the fastening position of the support member in contact with the housing or the interior of the equipment member”, and the member construction position output means 29 includes these definitions. Based on this, the designated point is automatically retrieved from the storage device 23, and its three-dimensional coordinates are extracted and output.

  Thereafter, based on the construction position information of the member object output from the member construction position output means 29 of the computer 20 as described above, the automatic position pointing device 40 determines the construction position of the member 51 in the existing portion as the irradiation point of the visible light laser. Point to as.

  As described above, according to the building production system according to the embodiment of the present invention, the construction object position information of the member object can be easily output by placing the newly placed construction member object in the polygon model of the existing part. Therefore, it is possible to reduce the labor of marking the member and prevent human error.

  In addition, information on existing drawings of buildings (completed drawings, etc.) and other parts of existing buildings are placed in the 3D space, and newly acquired measurement data and photo data are added, and 3D models are drawn. Since various building data can be centrally managed, survey and measurement data of existing parts of buildings can be efficiently organized.

  Furthermore, by pre-cutting and pre-fabricating members based on the shape and dimensions of existing parts at the member factory, cutting and processing of members on-site is not necessary, and member assembly can be facilitated. Labor costs can be reduced and construction waste can be reduced.

  Furthermore, since the construction position information is attached to each member by the electronic tag, positioning and installation can be performed simultaneously with the loading of the member, so that prior marking is unnecessary and the construction period can be shortened.

  In addition, since description of embodiment of the above-mentioned this invention has described suitable embodiment in the building production system which concerns on this invention, although technically preferable various restrictions may be attached | subjected. The technical scope of the present invention is not limited to these embodiments unless specifically described to limit the present invention. Furthermore, the components in the embodiment of the present invention described above can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible.
