Description
本発明は、建築物の改修工事や新築工事において、建築物の既存部分に対して新たに部材を設置する際に利用される建築生産システムに関する。 The present invention relates to a building production system used when a member is newly installed on an existing part of a building in a building renovation work or a new construction work.
一般に、建築物の改修工事や新築工事を行う場合、過去に施工された既存の躯体や設備或いは前工程での施工済みの躯体等の建築物の既存部分に対して、間仕切り壁、天井等の内装部材や配管、ダクト等の設備部材が新たに施工される。 In general, when renovating or constructing a building, partition walls, ceilings, etc. are used against existing parts and facilities that have been constructed in the past, or existing parts of the building that have been constructed in the previous process. Equipment members such as interior members, piping, and ducts are newly constructed.
従来、このように新たな部材を施工する場合、先ず、それぞれ単独で存在する、建築物の既存部分の竣工図や該既存部分を計測したデータや施工写真等から得た既存建築物のデータに基づき、新たに設置する内装部材や設備部材の仕様や寸法等が決定され、設計図や施工図が作成される（例えば、特許文献１参照）。 Conventionally, when constructing new members in this way, first of all, the existing building data obtained from the completed drawings of the existing parts of the building, the data of the existing parts measured, the construction photographs, etc. Based on this, specifications, dimensions, and the like of newly installed interior members and equipment members are determined, and design drawings and construction drawings are created (see, for example, Patent Document 1).
その後、この設計図や施工図に基づき、必要な部材が現場に搬入され、これらの部材は既存部分の躯体の凹凸形状に合うように現場加工により寸法や形状等が調整されると共に、部材の施工位置が墨出しされた上で、前記既存部分の躯体などに取り付けられる。 After that, based on this design drawing and construction drawing, necessary members are brought into the site, and these members are adjusted in size, shape, etc. by on-site processing to match the uneven shape of the existing part of the housing, After the construction position is marked, it is attached to the frame of the existing part.
しかしながら、従来、改修工事では、竣工図の不備や紛失等により建築物の既存部分に関する正確な図面情報が得られない場合が多く、また、新築・改修に関わらず施工済みの躯体や設備等をスケール等による手作業で計測しているため、計測精度に限界がある上に、施工誤差が存在する。そのため、建築物の既存部分に新たに施工される部材と該既存部分との隙間を充填材等で埋める等の現場合わせ作業や取り付け部材の現場加工作業が必要となるため、工数や労務費が増加するといった問題や、建築廃棄物が多く発生するといった問題がある。 However, in the past, in renovation work, there are many cases where accurate drawing information on existing parts of the building cannot be obtained due to incompleteness or loss of completed drawings, etc. Since the measurement is performed manually with a scale or the like, the measurement accuracy is limited and there is a construction error. For this reason, on-site alignment work such as filling the gap between the existing part of the building and the existing part with a filler, etc. and on-site processing work of the mounting member are required, so man-hours and labor costs are reduced. There are problems such as an increase and a large amount of building waste.
また、竣工図等の既存建築物のデータがそれぞれ単独で存在するため、設計図や施工図を作成する際に、それらの既存建築物のデータを整理するのに手間が掛かるといった問題もある。 In addition, since the data of existing buildings such as completed drawings exist individually, there is a problem that it takes time to organize the data of those existing buildings when creating design drawings and construction drawings.
さらに、部材の施工位置を墨出しする際、設計図や施工図に記載の寸法を参照し、手動で行っているため、手間が掛かる上に人的ミスが生じ易いといった問題もある。 Furthermore, when marking the construction position of the member, since it is performed manually with reference to the dimensions described in the design drawing and construction drawing, there is a problem that it takes time and human error is likely to occur.
本発明は、上記した課題を解決すべくなされたものであり、現場合わせ作業や現場加工作業をなくすことにより、工数や労務費を抑制し、建築廃棄物をゼロにすると共に、既存建築物のデータを効率よく整理し、墨出しの手間を軽減し、人的ミスの発生を防止することのできる建築生産システムを提供することを目的とするものである。 The present invention has been made to solve the above-mentioned problems, and by eliminating the work for on-site alignment and on-site processing, the number of man-hours and labor costs can be reduced, and construction waste can be reduced to zero. The object of the present invention is to provide a building production system that can efficiently organize data, reduce the labor of inking, and prevent human error.

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.
ディスプレイ２４上に３次元ＣＡＤの前記建築物の既存部分の平面図が表示された状態で入力装置２５により特定の２点がクリックされて線分が指定されると、ＣＰＵ２１は面墨生成手段３５として機能し、前記既存部分の躯体の３次元ポリゴンモデル４１（図４参照）から、前記線分を含む垂直面のうちポリゴンにより囲まれた切断面を、間仕切り壁が取り付けられる領域を示す面墨４６として切り出す。これにより、例えば、梁４２、壁４３、床スラブ４４及び天井スラブ４５等、躯体のポリゴンモデルの凹凸部に沿った形状の間仕切り壁の面墨４６が図５に示すように自動的に生成され、面墨４６はそれぞれＩＤナンバーが割り当てられた上で記憶装置２３に格納される。この面墨４６のＩＤナンバーは、その面墨４６を基準に作成される各部材の属性として引き継がれ、後述する部材集計時や施工位置情報として利用される他、部材の梱包や搬入時にも利用される。 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.
次いで、ディスプレイ２４上に３次元ＣＡＤの前記建築物の既存部分の立面図が表示された状態で、入力装置２５からの所定の操作により、記憶装置２３に格納された面墨の中から選択された特定の面墨４６に対して間仕切り壁の仕様（例えば、軸組み部材の厚み、逃げ寸法等）が指定された上で、始点Ｓと終点Ｅの２点がクリックされると、ＣＰＵ２１は部材オブジェクト配置手段３６として機能し、予め記憶装置２３のライブラリに登録されている部材オブジェクトの中から前記指定された仕様に合致する軸組み部材としてランナー４７を抽出し、始点Ｓと終点Ｅを端点とする寸法に調整した上でランナー４７を配置する。 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.
また、図５に示されているように、入力装置２５から上下のランナー４７が指定された上で、所定の配置位置Ｐが１点指定されると、ＣＰＵ２１は部材オブジェクト配置手段３６として機能し、予め記憶装置２３のライブラリに登録されている部材オブジェクトの中から軸組み部材としてスタッド４８を抽出し、前記所定の配置位置Ｐで上下のランナー４７を接続可能な寸法に調整した上でスタッド４８を鉛直姿勢で配置する。 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.
さらに、上記したように、入力装置２５からの所定の操作により、選択された面墨４６に対して間仕切り壁のボード４９（図８参照）の仕様（例えば、両面／片面、１枚貼り／２枚貼り、ボードの型式、ボードの上下左右の向き、ボードの分割ピッチ等）が指定されると、ＣＰＵ２１は部材オブジェクト配置手段３６として機能し、ボード４９の外周形状が面墨４６の形状に一致するようにボード４９を自動的に割り付け、前記軸組み部材上に配置する。
（３）部材データリスト（カットリスト）作成機能
次に、前記設計支援機能において配置された部材のリストを自動作成する「部材データリスト(カットリスト)作成機能」について説明する。
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.
入力装置２５から所定の操作を行うと、ＣＰＵ２１は部材データリスト作成手段３７として機能し、配置された新たに施工される部材オブジェクトの属性や形状及び寸法情報を記憶装置２３のライブラリから抽出し、各部材オブジェクトの加工寸法とともに部材オブジェクトのデータリストとして作成され、この部材オブジェクトデータリストは記憶装置２５に格納される。その際、上記のように面墨に合わせて配置された部材については、その面墨のＩＤナンバーに対応付けられた部材のデータリストとすることができ、また、面墨によらず、３次元ＣＡＤ上で指定した部材を要素とするデータリストを作成することもできる。 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.
その後、この部材オブジェクトのデータリストは、前記ＣＡＤデータと共に部材工場３０に送られる。該部材データリストには、基本データ項目として、例えは、面墨のＩＤ番号、ＣＡＤ上で自動的に割り当てられる部材のＩＤ番号、部材が示されている図面ファイルのパス名、部材が示されている図面ファイル名である作業ファイル名、部材が示されている図面ファイルが参照しているファイル名である参照ファイル名、部品の種類、部品の名称、部材の登録日、発注日、納品日、設置日等の日付などの各種データが格納されており、これらのデータはエクセル形式（ＣＳＶフォーマットなど）で出力可能となっている。 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).
部材工場３０では、前記部材オブジェクトの加工寸法リストに基づき、ＮＣ工作機械等によって各部材がプレカット又はプレカット後プレファブされて加工された後、該加工後の部材５１に電子タグ（ＲＦＩＤタグ）５２が取り付けられる。電子タグ５２には、部材オブジェクト固有のＩＤが記されており、このＩＤは部材５１のＩＤ番号に対応付けされている。 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.
なお、電子タグ５２のＩＤと部材５１のＩＤ番号とを対応付ける方法としては、例えば、前記部材データリスト（カットリスト）に電子タグ５２のＩＤを追記してコンピュータ２０側で対応付ける方法や、電子タグ５２を部材５１に貼り付けた後、対応する部材５１のＩＤを電子タグ５２に書き込む方法などがある。
（４）部材位置決め機能
次に、電子タグ読み取り機と３次元ＣＡＤが連携し、電子タグ５２に記されたＩＤに対応する部材オブジェクトをその施工位置情報と共に記憶装置２３から検索して自動位置指示装置４０に対して出力する「部材位置決め機能」について説明する。
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.
施工現場である前記建築物の既存部分へ部材５１が搬送され、電子タグ読み取り機であるＲＦＩＤリーダ５３によってＩＤが認識され、その情報がコンピュータ２０に送信されると、ＣＰＵ２１は部材施工位置出力手段２９として機能し、前記部材データリストの部材５１の納品日の欄に日付を記録することによりこの部材５１が納品されたことを記憶装置２３に記録すると同時に、前記ＣＡＤ上で前記ＩＤに該当する部材５１をハイライト表示する。 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.
この時、同一種類且つ同一寸法の部材５１が複数存在する場合、部材施工位置出力手段２９は、予め前記部材データリスト（カットリスト）に格納されている前記各部材５１の中から作業効率などを考慮して最適な部材を選択するために、ＲＦＩＤリーダ５３によって読み込んだＩＤに対応する部材５１と同一種類且つ同一寸法の全ての部材を認識する。そして、部材施工位置出力手段２９は、オペレータがそれらの部材５１の中から特定の部材を選択する際のモードとして、ＲＦＩＤリーダ５３で読み取ったＩＤに対応する部材オブジェクトと同一種類且つ同一加工寸法のすべての部材オブジェクトを前記３次元ＣＡＤ上でハイライト表示する手動選択モードと、ＲＦＩＤリーダ５３で読み取ったＩＤに対応する部材オブジェクトと同一種類且つ同一加工寸法のすべての部材オブジェクトの中から、予め指定された施工方向に従って順番に部材オブジェクトを選択し、３次元ＣＡＤ上でハイライト表示する方向固定モードと、ＲＦＩＤリーダ５３で読み取ったＩＤに対応する部材オブジェクトと同一種類且つ同一加工寸法のすべての部材オブジェクトの中から、直前に施工した部材オブジェクトに最も近接した位置に施工される部材オブジェクトを選択し、前記３次元ＣＡＤ上でハイライト表示する自動選択モード、の３つのモードを任意に選択可能なように構成されている。 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.
また、部材施工位置出力手段２９は、ＩＤにより部材５１の施工位置情報を記録装置２３に格納された前記ＣＡＤデータから読み出し、自動位置指示装置４０が指し示す点の位置データを出力する。この部材の指示点は、各部材５１の種類や用途、及び取り付け方法などによって最適な指示点が予め定義され、記憶装置２３に保存されており、部材施工位置出力手段２９は、３次元ＣＡＤ上に配置された各部材５１の位置と向きによって指示点の３次元座標を抽出し、出力する。 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.
一例として、新しく施工する部材５１を乾式間仕切り壁と仮定した場合、乾式間仕切壁は、床面及び天井面に取り付けられるランナー４７と、ランナー４７上に等間隔で配置されるスタッド４８と、ランナー４７及びスタッド４８の表面側に貼られる石膏ボード４９と、から構成される。 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.
ランナー４７は、図６に示されているように、両端部の各中央点がそれぞれ指示点ａとして定義される。また、スタッド４８は、ランナー４７上に所定の間隔で設置されることを考慮し、図７に示されているように、ランナー４７の側面或いはランナー４７脇の床面が指示点ｂとして定義される。さらに、石膏ボード４９は、スタッド４８がボード４９の目地になるように割り付けられることを考慮し、図８に示すように、ボード４９の角部が指示点ｃとして定義される。 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.
また、他の例として、新しく施工する部材５１を設備部材と仮定した場合、冷凍機やボイラー、ポンプなどの機器は、一般的には機械基礎に載せてボルト等で設置されるため、基礎上のボルト位置が指示点として定義される。一方、小型の機器や配管５４及びダクト５５等の設備部材は、専用の支持部材・架台等によって建築の躯体や内装材に取り付けられるため、部材自身の位置は空間上の点となり、レーザーで直接その位置を指し示すことは困難である。そのため、配管やダクト等、支持部材によって設置される設備部材は、支持部材の躯体等との締結位置（アンカーボルト等）が指示点として定義される。 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.
例えば、図９及び図１０に示すように、配管５４やダクト５５を天井スラブから吊り具５６により設置する場合、吊り具のためのアンカーボルトの位置が指示点として定義される（図９のｅ及び図１０のｆ参照）。また、配管５４やダクト５５を、床上に設置した支持架台上に載せて固定する場合は、その架台の床面でのアンカー位置が指示点として定義される（図示省略）。すなわち、新しく施工する部材５１が設備部材の場合の施工位置情報は、「設備部材に接する支持部材の躯体または内装との締結位置」として定義され、部材施工位置出力手段２９は、これらの定義に基づいて、指示点を記憶装置２３から自動検索し、その３次元座標を抽出し、出力する。 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.
その後、このようにコンピュータ２０の部材施工位置出力手段２９から出力された部材オブジェクトの施工位置情報に基づき、自動位置指示装置４０は、前記既存部分における部材５１の施工位置を可視光レーザーの照射点として指し示す。 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.
上記したように本発明の実施の形態に係る建築生産システムによれば、新たに配置される施工される部材オブジェクトを既存部分のポリゴンモデルに配置することにより部材オブジェクトの施工位置情報を簡単に出力することができるため、部材の墨出しの手間を削減し、人的ミスを防止することができる。 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.
また、建築物の既存図面（竣工図等）やその他の建物の既存部分に関する情報を３次元空間上に配置し、新たに取得した計測データや写真データなどの追加や３次元モデルの描画など、建物の各種データを一元管理することができるため、建築物の既存部分の調査及び計測データなどを効率よく整理することができる。 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.
さらに、部材工場で、既存部分の形状・寸法に基づいて部材をプレカットやプレファブ化することにより、現場での部材の切断・加工を不要にし、また部材組み立てを容易にすることができ、工数や労務費を抑制することができると共に、建設廃棄物の削減を図ることができる。 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.
さらにまた、電子タグにより各部材に施工位置情報を添付しているため、部材の搬入と同時に位置決めや据え付けが可能となり、事前の墨出しが不要となり、工期の短縮化を図ることができる。 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.
なお、上記した本発明の実施の形態の説明は、本発明に係る建築生産システムにおける好適な実施の形態を説明しているため、技術的に好ましい種々の限定を付している場合もあるが、本発明の技術範囲は、特に本発明を限定する記載がない限り、これらの態様に限定されるものではない。さらに、上記した本発明の実施の形態における構成要素は適宜、既存の構成要素等との置き換えが可能であり、かつ、他の既存の構成要素との組合せを含む様々なバリエーションが可能であり、上記した本発明の実施の形態の記載をもって、特許請求の範囲に記載された発明の内容を限定するものではない。 In addition, since description of embodiment of the above-mentioned this invention has demonstrated the preferred 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. The description of the embodiment of the present invention described above does not limit the contents of the invention described in the claims.
