Description

【０００１】
【発明の属する技術分野】
本発明は、鉄筋建造物を構築する際に用いる鉄筋の切断・屈曲・伸長仕様を算出する為の鉄筋加工仕様算出装置に関する。
【０００２】
【従来の技術】
今日の躯体積算システムには、特開２００１−１２３６６４号公報の如く図面編集装置等によってコンピュータシステムに予め登録した躯体構成要素の配置を示す配置データと、配置された躯体構成要素に各々与えられた内在部材リストデータに基づき、各躯体構成要素に含まれる内在部材の位置座標等を用いて三次元的な演算を施し、当該躯体に用いられる鉄筋の加工仕様を自動的に導き出す鉄筋加工仕様算出装置としての機能が備わっていた。
【０００３】
【発明が解決しようとする課題】
しかしながら、躯体は多くの躯体構成要素の組合せによるものであるから、各躯体構成要素の配置によって生じる鉄筋間の干渉や、鉄筋と鉄骨など同種或いは異種の内在部材間の干渉が存在する。それにも関わらず、従来の躯体積算システムの分野では、その様な干渉状態を、当該干渉状態に係る各内在部材の仕様や寸法等に基づき数値的に算出し出力する手段が無く、現場での実物合わせに委ねることがほとんどであった。
【０００４】
尚、前記寸法とは、各躯体構成要素の外寸である。前記内在部材とは、種々の躯体構成要素に内在する鉄筋や鉄骨等の主な部材を総称したものである。
【０００５】
本発明は、上記実情に鑑みて成されたものであって、コンピュータシステム上で、同種或いは異種の内在部材間の干渉状態を数値的に算出し、若しくはその様な干渉状態に対する対策を事前に施すことが出来る鉄筋加工仕様算出装置の提供を目的とする。
【０００６】
【課題を解決するための手段】
上記課題を解決するために成された本発明による鉄筋加工仕様算出装置は、各躯体構成要素の配置データ、内在部材リストデータに基づき、各躯体構成要素に含まれる鉄筋の線分を特定する三次元座標を取得すると共に、各躯体構成要素に含まれる鉄骨の表面又は芯面を特定する三次元座標を取得し、前記各表面又は芯面について、当該面を貫通する前記線分との交点座標を保存する干渉座標算出手段を具備したことを特徴とする。
【０００７】
各躯体構成要素の配置データ、内在部材リストデータに基づき、各躯体構成要素に含まれる鉄筋の線分の三次元座標及びその線分に関する属性を取得すると共に、各躯体構成要素に含まれる鉄骨の表面又は芯面の三次元座標及びその面に関する属性を取得し、前記各表面又は芯面について、当該面を貫通する線分との交点座標、貫通する線分のベクトル、並びに当該面及び線分各々の属性を保存する干渉座標算出手段を具備した構成としても良い。
【０００８】
尚、配置データとは、躯体構成要素の仕様及び配置座標並びに通芯に対する偏芯量など、配置する部材及び場所を特定する為に必要なデータであり、内在部材リストデータとは、躯体構成要素の仕様に応じて設定された鉄骨の配設状態や配筋状態を納めたデータ群である。前記線分とは、隣接する通過基準点（例えば、各鉄筋の端点や屈曲点など、当該鉄筋の位置及び形状を示す際の基点となり得る部分を指す。）間において鉄筋が直線的である場合は、当該直線部を指し、隣接する通過基準点間において鉄筋が湾曲している場合は、当該基準点間の湾曲部の両端点を結ぶ曲線を指す。
【０００９】
前記線分を特定する三次元座標、或いは表面又は芯面を特定する三次元座標とは、躯体が置かれる基準面（例えば水平面）をＸ軸及びＹ軸を含む平面と設定し、当該基準面と直交するＺ軸を加えた三次元座標系で示された座標であって、前記線分、或いは表面又は芯面の、位置及び範囲の特定に必要な端点又は頂点などの位置基準点の座標を、前記配置データが示す配置状況及び内在部材リストデータが示す配筋態様から算出したものである。加工仕様とは、何ｍｍの前記線分に続いて何処方向へ何度で屈曲させるといった加工の仕方を少なくとも数値的に示したものである。
【００１０】
【発明の実施の形態】
以下、本発明による加工仕様算出装置の実施の形態を図面に基づき説明する。本発明による加工仕様算出装置は、図１の如くいわゆるパーソナルコンピュータ等と、当該パーソナルコンピュータ等へ各種インターフェースを介して接続される入力装置及び出力装置とから構成された躯体積算関連システムの一役を担い、通常は、通芯、平面図、及び階名・階高、並びに躯体構成要素リスト及びそれらの各仕様をはじめとする躯体仕様を入力する為の図面編集装置５や、躯体に用いた鉄筋、鉄骨、コンクリート等の積算を行う為の躯体積算装置６などと共に、ハードウエア資源を共用した躯体積算システムを構築したものである。
【００１１】
前記パーソナルコンピュータ等は、周知の如く、ＣＰＵ、メモリー、及び記憶装置等のハードウエア資源を備えた一種のコンピュータシステムであり、記憶装置にインストールされたプログラム、或いは外部記憶装置に記録されたプログラムが起動することによって当該加工仕様算出装置の諸機能が起動することとなる。
【００１２】
上記図面編集装置によってパーソナルコンピュータへ前記躯体仕様が既に入力され、前記躯体仕様が、前記記憶装置等にデータベースとして保存されていることを前提として加工仕様算出装置を起動すれば、先ず、寸法決定手段８の稼働により各躯体構成要素の寸法が決定される（図２参照）。
【００１３】
寸法の決定は、連続基礎、柱及び梁の断面寸法、並びに連続基礎、スラブ及び壁の厚さにあっては、表１に示す如く、平面図を入力する際に、その仕様が明示された設計図書の図面・数値内容を登録する入力操作（数値入力やマウス操作等）によって自動設定或いは手動設定された三次元座標（躯体が置かれる基準面（例えば水平面）をＸ軸及びＹ軸を含む平面と設定し、当該基準面と直交するＺ軸を加えた三次元座標系で示された座標。以下同じ。）から算出される。
【００１４】
【表１】

【００１５】
また、連続基礎、柱及び梁の軸方向の寸法にあっては、表２に示す様に、当該躯体構成要素とその軸方向に存在する躯体構成要素との境界、又は当該躯体構成要素の始点と終点に基づいてその外縁が設定され、当該外縁の基点或いは始点又は終点など当該外縁を特定するに必要な三次元座標を算出し、当該三次元座標系における躯体構成要素の傾斜と湾曲を加味した増減を行う形で算出される。
【００１６】
【表２】

【００１７】
更に、スラブや壁の平面寸法にあっては、当該躯体構成要素の周囲に存在する躯体構成要素との境界、又は躯体構成要素の端辺に基づいてその外縁が設定され、当該外縁の基点或いは始点又は終点など当該外縁を特定するに必要な三次元座標を算出し、それに当該三次元座標系における躯体構成要素の傾斜と湾曲を加味した増減を行う形で算出される。上記算出方法のいずれにあっても、基本的に前記三次元座標で示されるポイント間の直線距離或いは曲線距離を算出するという形で行われ、後に、内在部材特定手段２８の稼働により予め設定された内在部材リストデータを参照して、躯体構成要素に含まれる内在部材及び当該躯体構成要素内における断面レイアウト（断面位置データ等）が特定され、前記の如く得られた寸法を用いて当該内在部材各々の加工仕様が導き出されることとなる。
【００１８】
独立した躯体構成要素に含まれる内在部材の加工仕様は、前記寸法と予め設定された内在部材リストデータから導き出されるが、特別に、柱、梁、連続基礎、スラブ等の連続して躯体の一部を形作る躯体構成要素にあっては、前記寸法の決定の他、連続情報取得手段７の稼働により、平面図に含まれる配置データからそれら躯体構成要素の連続状態が導き出されると共に、前記内在部材リストデータ等を参照しつつ角度算出手段２７によって前記連続状態にある躯体構成要素間の相対角度が算出される等して加工仕様が導き出される（図２参照）。
【００１９】
以下、仮に、折れ曲がった状態で連なる梁、及びそれに内包される鉄筋の連続状態を導き出す際の例を図４に基づき説明する。連続情報取得手段７は、躯体仕様を参照して、図４（イ）の如く順次選択された梁の芯線Ｐが向かう方向に断面が一部でも重なる梁９を検出し、前記躯体構成要素リストに含まれる内在部材リストデータに則って、長手方向に連なる梁９の内部に配設されるべき鉄筋１０を順次連結する（図４（ロ）参照）。特にこの例では、梁９を配置する際、その梁９の断面１１を配置するという形で行われるので、連続する梁群の始端断面１１ａから終端断面１１ｂに至るまで配置された梁９の断面を順次検出していくと言う形で行われる。
【００２０】
この処理は、連結されるべき鉄筋１０を内包する梁９を全て検出するまで行われるが、連結されるべき鉄筋１０を内包する梁９が平面図や躯体構成要素リストから観てまだ存在するにも関わらず、途中で当該梁９の芯線Ｐの方向で続く梁９の断面を検出できなくなった場合、即ち、前の梁９の芯線Ｐの向かう方向が次の梁９にて大きく変化した場合は、変化の始点となる断面に続く部分の芯線Ｐ、例えば、当該梁９の始端と末端、始端と中間点、又は末端と中間点との断面の中心の三次元座標を結ぶ芯線Ｐが新たな芯線Ｐとなり、各芯線Ｐに対して平行に配設される鉄筋１０の連結点が当該梁９の内部に配設される鉄筋１０の通過基準点１２となる。
【００２１】
更に、座標変換手段１３を起動し、各鉄筋１０の通過基準点１２の三次元座標を、鉄筋１０の線分を２つ以上含んだ仮想の面を基面１４とする相対的な三次元座標（以下、相対座標と記す。）に変換する。以下、図４（ロ）に示す柱の鉄筋の中から一本の鉄筋１０ａを抜粋して行った具体的な変換手順の一例を図５に基づき説明する。
【００２２】
尚、基面１４とは、前記加工仕様を表す際に最も都合が良いと選択された面である。具体的には、各鉄筋１０に含まれる二つの線分１５，１５と平行な平面を以て基面１４とするのが、折り曲げ作業を少しでも省略できる点で効率的であるが、基面１４を構成するものとして選択される線分１５によって加工時における作業性も異なり、各鉄筋１０が含む線分１５のうちで最も長い線分１５ａと２番目に長い線分１５ｂを含む平面を以て基面１４とすることが便利な場合が多く、同様の見方からすれば、各鉄筋１０が含む線分１５のうちで最も長い線分１５ａを基軸１６とするのが便利な場合も多い。
【００２３】
１）　前記通過基準点を結ぶ線分１５のうち最も長い線分（この例ではこれを基軸１６とする。）１５ａを鉄筋から検出する。
２）　前記基軸１６が当該相対座標系のＸ軸と平行となるように複数の線分１５が連結して成る対象鉄筋１０ａ全体を移動させ、対象鉄筋１０ｂとして各通過基準点１２の座標を更新する。
３）　前記通過基準点１２を結ぶ線分のうち２番目に長い線分１５ｂを検出する。
４）　２番目に長い線分１５ｂが当該相対座標系のＸＹ平面に対して平行となるようにそのＸ軸と平行な軸を中心に前記鉄筋１５ｂ全体を回転させ、対象鉄筋１０ｃとして各通過基準点１２の座標を更新する（この例では、ここで更新された座標を相対座標とし、前記基軸１６、即ち、最も長い線分１５ａと２番目に長い線分１５ｂとで定まる面を基面１４とした。）。
【００２４】
続いて、角度算出手段２７は、この様に変換されて成る相対座標を用いて、基軸１６以外の各線分１５について前記基軸１６と他の線分１５との相対角度を、前記基軸１６を含んだ基面１４に対する水平角α及び垂直角βという形で算出する。算出結果は、適宜設けられた出力装置へ、例えば、対象鉄筋１０ｃ全体を、図５（ロ）の如く、前記相対座標系のＸ−Ｙ平面、Ｘ−Ｚ平面、場合によってはＹ−Ｚ平面へ投影した２次元の図面を以て表示し、それぞれの図面において各線分１５にかかる水平角α及び垂直角β並びに長さを表記しておけば良い。
【００２５】
尚、上記表示方法を挙げたことによって、必要に応じて基軸１６以外の線分１５との相対角度で示すことを妨げるものではなく、場合によっては、図８の二点鎖線円内に示す如く隣接する通過基準点１２，１２で定まる線分１５の長さと、隣接する通過基準点１２，１２間の差分座標によって表す場合もある。隣接する通過基準点１２，１２間の差分座標とは、前記隣接する通過基準点１２，１２間の三次元座標の差分を絶対値で示したものであり、この場合も、前記相対角度で示す場合と同様の基準を持って相対座標系の基面１４を設定することが有効となる。
【００２６】
この様な加工仕様算出処理は、図６及び図７に示す曲線的な梁９を含む処理にも適用出来、その際も、各鉄筋１０の加工仕様を、隣接する通過基準点１２，１２で定まる線分１５の長さと、当該鉄筋１０が含む線分１５から選択した基軸１６と他の線分１５との相対角度又は隣接する通過基準点１２，１２間の差分座標により、当該湾曲部１７の曲がり量をも含めて充分明確に示すことができるものである。
【００２７】
前記のごとく、前記内在部材特定手段２８の稼働によって、予め設定された躯体仕様を参照して、当該躯体構成要素に含まれる内在部材が特定されるが、内在部材として鉄骨が含まれる場合もあり得る。この様な場合、前記躯体仕様に含まれる内在部材リストデータには、例えば、梁や柱等の場合は、コンクリートの断面形状及び鉄骨の断面形状等がその相対位置を示す形で含まれており、因みに、内在部材に含まれないその他の鉄骨の位置情報は、前記躯体仕様に平面図や立面図としてその断面形状、並びに配置データに基づく絶対位置が登録されている。
【００２８】
そして、折れ曲がった状態で連なる梁、及びそれに内包される鉄骨の連続状態を導き出すにあたり、連続情報取得手段７は、躯体仕様を参照して、図１１（イ）の如く順次選択された梁の芯線Ｐが向かう方向に断面が一部でも重なる梁９を検出し、前記躯体構成要素リストに含まれる内在部材リストデータに則って、長手方向に連なる梁９の内部に配設されるべき鉄骨１８を構成している各表面（ここでは表面１９を用いたが、処理スピード等を考慮して芯面を用いても良い）１９を順次連結する（図１１（ロ）参照）。そして、必要に応じ、各表面１９の端辺を連結することによって、連続する鉄骨１８の連結部の断面が特定され、鉄骨１８の連結等の作業に適宜利用される。尚、上記鉄骨前記鉄筋１０の連続情報を得る場合と同様に、この例では、梁９を配置する際、その梁９の断面１１を配置するという形で行われるので、連続する梁群の始端断面１１ａから終端断面１１ｂに至るまで配置された梁９の断面を順次検出していくと言う形で行われる。
【００２９】
しかしながら、前記の如く鉄筋１０の加工仕様が導かれた躯体構成要素は、それ自体が単体で存在するわけではなく、複数の躯体構成要素と連結し、各躯体構成要素に包含される鉄筋１０や鉄骨１８が相互に組み合って存在する。よって、上記の如く単純に各躯体構成要素及びそれに包含される鉄筋１０や鉄骨１８の加工仕様を導き出すだけでは、相連結する躯体構成要素に含まれる鉄筋１０や鉄骨１８が相互に干渉し、実際の現場において極めて煩雑な修正加工を施す必要が生じる場合が少なくない。殊に、鉄筋１０と鉄骨１８とが、図９及び図１０の如く干渉し合う場合には、鉄骨１８に対して鉄筋１０が通過する孔を設けなければならず、その様な孔を現場作業中に設けることは、予め孔を設けておく場合と比較して時間的なロスも大きくなる。
【００３０】
上記実情に鑑み、当該加工仕様算出装置は、干渉座標算出手段１によって躯体構成要素に含まれる内在部材間の干渉座標の算出処理を行うことが出来るように設計されている。以下、当該干渉座標算出処理の具体例を、鉄骨１８と鉄筋１０とが相互に干渉している場合に基づき説明する。
【００３１】
先ず、躯体仕様から各躯体構成要素に含まれる鉄筋１０に含まれる線分１５の前記三次元座標及びその線分１５に関する属性（径をはじめとする鉄筋１０の仕様等）を取得し、更に、同躯体仕様から各躯体構成要素に含まれる前記鉄骨１８の表面（平面であるか曲面であるかは問わない。）１９の三次元座標及びその面に関する属性（厚みや幅をはじめとする鉄骨の仕様等）を取得する。そして、前記各鉄骨１８の表面１９について、当該鉄骨１８の表面１９を貫通している鉄筋１０の持つ線分１５との交点座標と当該線分１５の方向ベクトル、並びに当該表面１９及び線分１５各々の属性を保存する。
【００３２】
尚、前記鉄筋１０の持つ線分１５として用いるものは、鉄筋の中心を通る軸であっても良いが、太さを考慮すべく、鉄筋１０自体をＮ角柱として仮定し、前記軸を中心とした半径（鉄筋１０の太さ／２）の周面上に存在するＮ（任意の自然数）本の稜線であっても良い（図３（ハ）（ニ）参照）。また、鉄骨１８の面を表現するものとして用いられるものには、前記連続情報を得る場合と同様に、平面、旋回曲面、球面、ベジエ曲面、Ｂスプライン曲面等が挙げられる。前記干渉座標算出処理の対象となる鉄骨１８の面（交点が算出される面）としては、鉄骨１８の表面を採用しても良いし、面厚を考慮せず鉄骨１８の芯面を採用しても良い（図３（イ）（ロ）参照）。
【００３３】
上記の如く、鉄骨１８の表面１９を構成する平面或いは当該鉄骨１８の芯となる芯面と、当該鉄骨１８と干渉する鉄筋１０の特定線分１５との交点の算出結果及び前記鉄筋１０及び鉄骨１８の属性（或いは面及び線分１５の属性）から、鉄骨１８を貫通する鉄筋１０が通過する為の孔の場所及び寸法を導き出すことができる。前記軸を用いる場合は、前記交点座標を中心とする孔として導かれ、前記稜線を用いる場合には、各稜線との交点座標を結んだ孔として導かれる。また、鉄筋１０同士の干渉にあっても、相干渉する鉄筋１０の特定線分１５の三次元座標及びそれら鉄筋１０に関する前記属性を取得し、それらの交点を算出することによって、切断等を行う箇所並びに寸法を導き出すことができる。
【００３４】
【発明の効果】
以上の如く、本発明による加工仕様算出装置によれば、各躯体構成要素の配置データ、内在部材リストデータに基づき、各躯体構成要素に含まれる鉄筋の線分の三次元座標を取得すると共に、各躯体構成要素に含まれる鉄骨の表面又は芯面の三次元座標を取得し、前記各表面又は芯面について、当該面を貫通する線分との交点座標を保存する干渉座標算出手段を具備した構成によって、鉄骨表面を構成する平面或いは当該鉄骨の芯となる芯面と、当該鉄骨と干渉する鉄筋の線分との交点の算出結果から、鉄骨を貫通する鉄筋が通過する為の孔の場所を導き出すことができる。
【００３５】
また、各躯体構成要素の配置データ、内在部材リストデータに基づき、各躯体構成要素に含まれる鉄筋の線分の三次元座標及びその線分に関する属性を取得すると共に、各躯体構成要素に含まれる鉄骨の表面又は芯面の三次元座標及びその面に関する属性を取得し、前記各表面又は芯面について、当該面を貫通する線分との交点座標、貫通する線分のベクトル、並びに当該面及び線分各々の属性を保存する干渉座標算出手段を具備した構成によって、鉄骨表面を構成する平面或いは当該鉄骨の芯となる芯面と、当該鉄骨と干渉する鉄筋の線分との交点の算出結果及び前記鉄筋及び鉄骨の属性から、鉄骨を貫通する鉄筋が通過する為の孔の場所及び寸法を導き出すことができる。現場での実物合わせという手間のかかる作業も回避できる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a rebar processing specification calculation device for calculating specifications of cutting, bending, and elongation of a rebar used when constructing a rebar building.
[0002]
[Prior art]
In today's skeleton integration system, as shown in Japanese Patent Application Laid-Open No. 2001-123664, layout data indicating the layout of skeleton components registered in advance in a computer system by a drawing editing device and the like, and the allocated skeleton components are given.

[0003]
[Problems to be solved by the invention]
However, since the skeleton is based on a combination of many skeleton components, there is interference between reinforcing bars caused by the arrangement of each skeleton component, and interference between the same type or different types of internal members such as reinforcing bars and steel frames. Nevertheless, in the field of the conventional skeleton integration system, there is no means for numerically calculating and outputting such an interference state based on the specifications and dimensions of the respective internal members related to the interference state. In most cases, it was left to actual matching.
[0004]
In addition, the said dimension is an outer dimension of each skeleton component. The term "internal members" is a general term for the main members such as reinforcing bars and steel frames existing in various structural elements.
[0005]
The present invention has been made in view of the above circumstances, and numerically calculates an interference state between similar or different types of internal members on a computer system, or takes measures against such an interference state in advance. It is an object of the present invention to provide a rebar processing specification calculation device that can be applied.
[0006]
[Means for Solving the Problems]
The rebar processing specification calculation device according to the present invention made to solve the above-mentioned problem is based on a tertiary line that specifies a line segment of a reinforcing bar included in each skeleton component based on the arrangement data of each skeleton component and the list of inherent members. Acquire the original coordinates, obtain the three-dimensional coordinates that specify the surface or the core surface of the steel frame included in each skeleton component, for each of the surfaces or the core surface, the intersection coordinates with the line segment passing through the surface Is provided.
[0007]
Based on the arrangement data of each skeleton component and the list of intrinsic members, acquire the three-dimensional coordinates of the line segments of the reinforcing bars included in each skeleton component and the attributes related to the line segments, as well as the attributes of the steel frames included in each skeleton component. Obtain the three-dimensional coordinates of the surface or the core surface and the attributes related to the surface, and for each surface or core surface, the coordinates of the intersection with the line segment passing through the surface, the vector of the line segment passing through, and the surface and the line segment A configuration including interference coordinate calculation means for storing each attribute may be employed.
[0008]
Note that the arrangement data is data necessary for specifying a member and a place to be arranged, such as the specification and arrangement coordinates of the skeleton component and the amount of eccentricity with respect to the grid. The inherent member list data is the skeleton component element. Is a data group containing the arrangement state and the arrangement state of the steel frames set according to the specifications of FIG. The above-mentioned line segment is a case where a reinforcing bar is linear between adjacent passing reference points (for example, a portion that can be a base point when indicating the position and shape of the reinforcing bar, such as an end point or a bending point of each reinforcing bar). Indicates the straight line portion, and when the rebar is curved between adjacent passing reference points, indicates a curve connecting both end points of the curved portion between the reference points.
[0009]
The three-dimensional coordinates for specifying the line segment or the three-dimensional coordinates for specifying the surface or the core surface refer to a reference plane (for example, a horizontal plane) on which a skeleton is placed as a plane including the X axis and the Y axis, and the reference plane. And coordinates of a position reference point such as an end point or a vertex necessary for specifying the position and range of the line segment or the surface or the core surface, the coordinate being indicated by a three-dimensional coordinate system to which the Z axis orthogonal to the above is added. Is calculated from the arrangement state indicated by the arrangement data and the arrangement of bars indicated by the intrinsic member list data. The processing specification indicates at least numerically a processing method in which the line segment of several millimeters is bent in any direction after the line segment.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a processing specification calculation device according to the present invention will be described with reference to the drawings. The processing specification calculation apparatus according to the present invention plays a role of a skeleton integration system including a so-called personal computer as shown in FIG. 1 and an input device and an output device connected to the personal computer and the like via various interfaces. , Usually, a drawing editing apparatus 5 for inputting a core specification, such as a grid, a floor plan, a floor name and a floor height, and a list of frame component elements and their specifications, and a reinforcing bar used for the frame, A skeleton integration system that shares hardware resources is constructed together with a skeleton integration device 6 for integrating steel frames, concrete, and the like.
[0011]
As is well known, the personal computer or the like is a type of computer system having hardware resources such as a CPU, a memory, and a storage device, and a program installed in the storage device or a program recorded in an external storage device is stored in the storage device. Upon activation, various functions of the processing specification calculation device are activated.
[0012]
If the machining specification calculator is started on the premise that the skeleton specification has already been input to the personal computer by the drawing editing apparatus and the skeleton specification is stored as a database in the storage device or the like, first, the dimension determining means The operation of 8 determines the dimensions of each frame component (see FIG. 2).
[0013]
As for the determination of the dimensions, as for the continuous foundation, the cross-sectional dimensions of columns and beams, and the thickness of the continuous foundation, slabs and walls, as shown in Table 1, the specifications were specified when entering the plan view. The three-dimensional coordinates (reference plane (for example, horizontal plane) on which the skeleton is placed) including the X axis and the Y axis automatically set or manually set by an input operation (numerical input, mouse operation, etc.) for registering drawings and numerical contents of design documents The coordinates are expressed in a three-dimensional coordinate system in which a plane is set and a Z axis orthogonal to the reference plane is added.
[0014]
[Table 1]

[0015]
In addition, for the dimensions of the continuous foundation, columns and beams in the axial direction, as shown in Table 2, the boundary between the skeleton component and the skeleton component existing in the axial direction, or the starting point of the skeleton component The outer edge is set based on the and the end point, and the three-dimensional coordinates necessary to specify the outer edge such as the base point or the start point or the end point of the outer edge are calculated, and the inclination and curvature of the skeleton component in the three-dimensional coordinate system are taken into account. It is calculated in such a way as to increase or decrease it.
[0016]
[Table 2]

[0017]
Furthermore, in the plane dimensions of the slab or the wall, the outer edge is set based on the boundary with the skeleton component existing around the skeleton component, or the edge of the skeleton component, and the base point of the outer edge or The three-dimensional coordinates required to specify the outer edge such as the start point or the end point are calculated, and the calculation is performed in such a manner as to increase or decrease the inclination and curvature of the skeleton component in the three-dimensional coordinate system. In any of the above calculation methods, the calculation is basically performed by calculating a linear distance or a curve distance between the points indicated by the three-dimensional coordinates, and is set in advance by the operation of the intrinsic member specifying unit 28. With reference to the internal member list data, the internal members included in the skeleton component and the cross-sectional layout (cross-sectional position data and the like) in the skeleton component are specified, and the internal members are determined using the dimensions obtained as described above. Each processing specification will be derived.
[0018]
The processing specifications for the internal members included in the independent skeleton components are derived from the above dimensions and the preset internal member list data, but in particular, columns, beams, continuous foundations, slabs, etc. In the skeleton components forming the part, in addition to the determination of the dimensions, the operation of the continuous information acquisition means 7 derives the continuity of the skeleton components from the arrangement data included in the plan view, The processing specification is derived by calculating the relative angle between the skeleton components in the continuous state by the angle calculating means 27 while referring to the list data or the like (see FIG. 2).
[0019]
Hereinafter, an example of deriving a continuous state of the beams connected in a bent state and the reinforcing bars included therein will be described with reference to FIG. The continuity information acquisition means 7 detects the beam 9 whose cross section partially overlaps in the direction toward the core line P of the sequentially selected beam as shown in FIG. The rebars 10 to be disposed inside the beams 9 extending in the longitudinal direction are sequentially connected in accordance with the intrinsic member list data included in (1) (see FIG. 4B). In particular, in this example, when arranging the beam 9, the cross section 11 of the beam 9 is arranged. Therefore, the cross section of the beam 9 arranged from the start end section 11 a to the end section 11 b of the continuous beam group is performed. Are sequentially detected.
[0020]
This process is performed until all the beams 9 including the reinforcing bars 10 to be connected are detected. However, if the beams 9 including the reinforcing bars 10 to be connected still exist as viewed from the plan view or the skeleton component list. Nevertheless, when the cross section of the beam 9 that continues in the direction of the core P of the beam 9 cannot be detected on the way, that is, when the direction of the core P of the previous beam 9 changes greatly in the next beam 9 Is the center line P of the portion following the cross section serving as the start point of the change, for example, the center line P connecting the three-dimensional coordinates of the center of the cross section between the start end and the end, the start end and the middle point, or the end and the middle point of the beam 9 is newly added. The connection points of the reinforcing bars 10 arranged in parallel to the respective core lines P become the passage reference points 12 of the reinforcing bars 10 disposed inside the beam 9.
[0021]
Further, the coordinate conversion means 13 is activated, and the three-dimensional coordinates of the passage reference point 12 of each reinforcing bar 10 are set as relative three-dimensional coordinates with a virtual surface including two or more line segments of the reinforcing bar 10 as the base surface 14. (Hereinafter referred to as relative coordinates). Hereinafter, an example of a specific conversion procedure performed by extracting one reinforcing bar 10a from the column reinforcing bars illustrated in FIG. 4B will be described with reference to FIG.
[0022]
In addition, the base surface 14 is a surface selected to be most convenient when expressing the processing specifications. Specifically, it is efficient to use a plane parallel to the two

line segments

15 and 15 included in each rebar 10 as the base surface 14 in that the bending operation can be omitted even a little. The workability at the time of machining differs depending on the line segment 15 selected as a constituent, and the base surface 14 has a plane including the longest line segment 15a and the second longest line segment 15b among the line segments 15 included in each reinforcing bar 10. In many cases, it is convenient to use the longest line segment 15a among the line segments 15 included in each reinforcing bar 10 as the base axis 16.
[0023]
1) The longest line segment 15a (in this example, the base axis 16) of the line segments 15 connecting the passing reference points is detected from the reinforcing bar.
2) The entire target rebar 10a formed by connecting the plurality of line segments 15 is moved so that the base axis 16 is parallel to the X axis of the relative coordinate system, and the coordinates of each passage reference point 12 are updated as the target rebar 10b. I do.
3) The second longest line segment 15b among the line segments connecting the passage reference points 12 is detected.
4) The entire reinforcing bar 15b is rotated around an axis parallel to the X axis so that the second longest line segment 15b is parallel to the XY plane of the relative coordinate system, and each passing reference is set as the target reinforcing bar 10c. The coordinates of the point 12 are updated (in this example, the updated coordinates are set as relative coordinates, and the base axis 16, that is, a plane defined by the longest line segment 15a and the second longest line segment 15b is set as the base surface 14). And.).
[0024]
Subsequently, the angle calculation unit 27 uses the relative coordinates converted in this way to calculate the relative angle between the base axis 16 and the other line segments 15 for each of the line segments 15 other than the base axis 16, including the base axis 16. The horizontal angle α and the vertical angle β with respect to the base surface 14 are calculated. The calculation result is output to an appropriately provided output device by, for example, transferring the entire target reinforcing bar 10c to the XY plane, the XZ plane, or the YZ plane of the relative coordinate system as shown in FIG. , The horizontal angle α and the vertical angle β and the length of each line segment 15 may be described in each drawing.
[0025]
It should be noted that the above display method does not prevent the relative angle with the line segment 15 other than the base axis 16 from being indicated as necessary. In some cases, as shown in a two-dot chain line circle in FIG. In some cases, the distance may be represented by the length of a line segment 15 determined by the adjacent passage reference points 12 and 12 and the difference coordinates between the adjacent passage reference points 12 and 12. The difference coordinates between the adjacent passage reference points 12 and 12 indicate the difference between the three-dimensional coordinates between the adjacent passage reference points 12 and 12 by an absolute value, and also in this case, are indicated by the relative angles. It is effective to set the base surface 14 of the relative coordinate system with the same reference as in the case.
[0026]
Such processing specification calculation processing can also be applied to the processing including the curved beam 9 shown in FIGS. 6 and 7, and also in this case, the processing specifications of each reinforcing bar 10 are set at the adjacent passage reference points 12 and 12. The curved portion 17 is determined by the length of the determined line segment 15 and the relative angle between the base axis 16 selected from the line segment 15 included in the rebar 10 and another line segment 15 or the difference coordinates between the adjacent passage reference points 12 and 12. Can be sufficiently clearly shown, including the amount of bending.
[0027]
As described above, the operation of the intrinsic member specifying means 28 refers to a preset skeleton specification to identify the intrinsic member included in the skeleton component.However, a steel frame may be included as the intrinsic member. obtain. In such a case, the inherent member list data included in the skeleton specification includes, for example, in the case of a beam or a column, the cross-sectional shape of concrete and the cross-sectional shape of a steel frame are included in a form indicating their relative positions. Incidentally, as for the position information of other steel frames not included in the inherent members, the sectional shape and the absolute position based on the arrangement data are registered in the frame specification as a plan view or an elevation view.
[0028]
Then, in deriving the continuous state of the beam connected in the bent state and the steel frame included therein, the continuous information obtaining means 7 refers to the frame specification and refers to the core line of the beam sequentially selected as shown in FIG. The beam 9 whose cross section is partially overlapped in the direction of P is detected, and the steel frame 18 to be disposed inside the beam 9 extending in the longitudinal direction is determined in accordance with the intrinsic member list data included in the skeleton component list. The constituent surfaces (the surface 19 is used here, but a core surface may be used in consideration of the processing speed and the like) 19 are sequentially connected (see FIG. 11B). Then, if necessary, by connecting the edges of the respective surfaces 19, the cross section of the continuous connecting portion of the steel frame 18 is specified, and the cross section of the connecting portion of the steel frame 18 is appropriately used for operations such as the connection of the steel frame 18. In this example, as in the case where the continuous information of the steel bars 10 is obtained, in this example, when arranging the beam 9, the cross section 11 of the beam 9 is arranged. This is performed by sequentially detecting the cross sections of the beams 9 arranged from the cross section 11a to the terminal cross section 11b.
[0029]
However, the skeleton component from which the processing specifications of the reinforcing bar 10 are derived as described above does not exist as a single unit, but is connected to a plurality of skeleton components, and the reinforcing bar 10 included in each skeleton component and Steel frames 18 are present in combination with each other. Therefore, as described above, simply deriving the processing specifications of each skeleton component and the reinforcing bars 10 and the steel frames 18 included therein will cause the reinforcing bars 10 and the steel frames 18 included in the mutually connected skeleton components to interfere with each other. In many cases, it is necessary to perform extremely complicated correction processing at the site. In particular, when the reinforcing bar 10 and the steel frame 18 interfere with each other as shown in FIGS. 9 and 10, a hole through which the reinforcing bar 10 passes must be provided in the steel frame 18. The provision in the inside also increases the time loss compared to the case where holes are provided in advance.
[0030]
In view of the above circumstances, the machining specification calculation device is designed so that the interference coordinate calculation means 1 can perform a process of calculating interference coordinates between the internal members included in the skeleton component. Hereinafter, a specific example of the interference coordinate calculation process will be described based on a case where the steel frame 18 and the reinforcing bar 10 interfere with each other.
[0031]
First, the three-dimensional coordinates of the line segment 15 included in the reinforcing bar 10 included in each skeleton component and attributes (such as the diameter of the reinforcing bar 10 and the like) of the line segment 15 are acquired from the skeleton specification, and further, From the same frame specification, the three-dimensional coordinates of the surface 19 (regardless of whether it is a flat surface or a curved surface) 19 of the steel frame 18 included in each frame component and attributes related to the surface (thickness and width, etc. Specifications etc.). Then, for the surface 19 of each steel frame 18, the coordinates of the intersection with the line 15 of the reinforcing bar 10 penetrating the surface 19 of the steel frame 18, the direction vector of the line 15, and the surface 19 and the line 15. Save each attribute.
[0032]
In addition, what is used as the line segment 15 of the rebar 10 may be an axis passing through the center of the rebar, but in consideration of the thickness, the rebar 10 itself is assumed to be an N prism, and the axis is defined as the center. N (arbitrary natural number) ridges may be present on the peripheral surface of the radius (the thickness of the reinforcing bar 10/2) (see FIGS. 3 (c) and (d)). In addition, as those used to express the surface of the steel frame 18, a plane, a turning surface, a spherical surface, a Bezier surface, a B-spline surface, and the like can be used as in the case of obtaining the continuous information. As the surface of the steel frame 18 (the surface on which the intersection is calculated) to be subjected to the interference coordinate calculation processing, the surface of the steel frame 18 may be employed, or the core surface of the steel frame 18 may be employed without considering the surface thickness. (See FIGS. 3A and 3B).
[0033]
As described above, the calculation result of the intersection between the plane constituting the surface 19 of the steel frame 18 or the core surface serving as the core of the steel frame 18 and the specific line segment 15 of the reinforcing bar 10 which interferes with the steel frame 18 and the calculation result of the intersection point between the rebar 10 and the steel frame From the attribute 18 (or the attribute of the surface and the line segment 15), it is possible to derive the location and size of the hole through which the reinforcing bar 10 passing through the steel frame 18 passes. When the axis is used, it is guided as a hole centered on the intersection coordinates, and when the ridge line is used, it is guided as a hole connecting the intersection coordinates with each ridge line. Further, even in the case of interference between the reinforcing bars 10, cutting or the like is performed by acquiring the three-dimensional coordinates of the specific line segment 15 of the reinforcing bars 10 that interfere with each other and the above-described attributes related to the reinforcing bars 10, and calculating their intersections. Locations and dimensions can be derived.
[0034]

The troublesome work of actual matching on site can also be avoided.
