Description

【０００１】
【発明の属する技術分野】
本発明は、格子体、およびこの格子体を用いた面格子に関する。
【０００２】
【背景技術】
従来より、建物の外壁開口部等に取り付けられる面格子や、階段、通路、バルコニー等に設けられる手摺り、柵（フェンス）、門扉等に用いられる格子体が知られている。このような格子体として、躯体等に固定される枠体と、この枠体の内側に取り付けられた複数の縦桟とから構成された格子体が提案されている（例えば、特許文献１参照）。特許文献１に記載された格子体（格子材）では、上側の枠材が下方に開口した断面略Ｃ字形に形成され、この枠材の開口部分に縦桟を挿入するとともに、枠材の開口部分を室内外両側から縦桟に向かって加圧し、互いを溶接、固定して、一体に形成されている。
【０００３】
【特許文献１】
実開昭５２−３２５７号公報
【０００４】
【発明が解決しようとする課題】
しかしながら、特許文献１に記載の格子体では、枠材のＣ字形の開口部分に縦桟を挿入しただけでは、溶接して固定する際に互いの部材が安定しないので、枠材および縦桟を位置決めした状態で仮固定しておく必要があり、組立作業の作業効率が低いという問題がある。
また、枠材および縦桟の溶接固定部分が枠材の室内外両側に露出しているため、格子体の外観の意匠性が損なわれるという問題もある。
【０００５】
本発明の目的は、組立作業の作業効率向上を図ることができ、かつ、外観を良好にできる格子体、およびこの格子体を用いた面格子を提供することにある。
【０００６】
【課題を解決するための手段】
本発明の格子体は、所定間隔離れて設けられた一対の長尺な支持材と、これらの支持材間に架設された複数の桟材とを備えた格子体であって、前記各支持材は、前記複数の桟材の端部が挿通される複数の挿通孔を有した交差面部と、この交差面部の長手方向に沿った両側端縁から、他の支持材から離れる方向にそれぞれ延出された２つの側面部とを備え、前記２つの側面部のうち、一方の側面部に前記桟材の側面が当接して固定されていることを特徴とする。
【０００７】
このような本発明によれば、支持材の交差面部に設けた挿通孔に桟材を挿通することで、桟材と交差した支持材の長手方向および直交方向について、桟材を位置決め可能であるとともに、支持材の一方の側面部を桟材の側面に当接することで、挿通孔および側面部の少なくとも２箇所で桟材と当接するため、支持材に沿った軸線を中心とした回転方向についても、桟材を位置決め可能である。従って、格子体の組み立てに際して、支持材および桟材が安定して位置決めされた状態で、溶接等による固定作業を実施することができ、組立作業の作業効率向上を図ることができる。
また、支持材の一方側に形成された側面部を、桟材の側面に固定することで、例えば、溶接により両部材を固定した場合には、固定部分である溶接ビードが他方側の側面には表れず、他方側をより人目に付く側に向けて設置すれば、外観を良好にすることができる。
【０００８】
さらに、挿通孔が設けられた交差面部の両側端縁に側面部が連続して形成されているので、挿通孔周辺の部材強度を確保できるため、室内に侵入を謀ろうとする者が挿通孔部分から支持材を破壊しづらくし、防犯性を高めることができる。また、従来の格子体においては、下側の枠材と縦桟とが固定されておらず、上下の枠材を連結する縦枠材等が必要であるが、本発明の格子体では、２本の支持材のいずれもが、桟材に固定されるため、これら２本の支持材を連結する枠材を不要にでき、部品点数を削減することができる。さらに、本発明の格子体では、２本の支持材を同一部品から構成できるため、部品の共通化を図ることができる。
【０００９】
この際、本発明の格子体では、前記一方の側面部は、前記交差面部と略平行で、かつ前記桟材の側面に向って折り曲げた折曲部を有し、この折曲部が前記桟材の側面に当接していることを特徴とする。
このような構成では、支持材の一方側に形成された側面部を桟材に向かって折り曲げ、この折曲部を桟材の側面に当接、固定したので、２本の支持材の間隔内側であれば格子体から多少離れた位置からであっても、折曲部に隠れて固定部分を見えなくできるので、さらに外観を良好にすることができる。
【００１０】
さらに、本発明の格子体では、前記支持材は、前記２つの側面部のうちの他方の側面部に連続して形成され、かつ前記交差面部と対向配置される外面部を備え、この外面部に前記桟材の先端が当接していることを特徴とする。
このような構成では、支持材の他方側に形成された側面部に連続して、桟材の先端が当接する外面部を形成することで、桟材の先端を支持材で覆うことができ、例えば、桟材を中空パイプ状の部材で構成した場合などに、桟材の内部への雨水等の浸入を防止できる。また、格子体の組み立てに際して、支持材の外面部に桟材の先端を当接することで、桟材に沿った方向の位置決めが可能になり、組立作業の作業効率をさらに向上させることができる。
【００１１】
また、本発明の格子体では、前記２本の支持材が互いに上下に対向し、かつ、略水平に配置されることを特徴とする。
このような構成では、２本の支持材を互いに上下に、かつ水平にして設置することで、桟材が上下方向に延びる一般的な面格子、手摺り、柵、門扉等を構成できるとともに、支持材が上下対称に配置されるので、外観のデザインを統一し、意匠性を向上させることができる。
また、従来の格子体において、上下の枠材を共通化して、デザインを統一しようとすれば、上側の枠材を上下反転させて下側に配置することも可能であるが、断面略Ｃ字形の枠材を上方に開口させて配置すると、枠材内部に浸入した雨水等が排出されづらく、この水が枠材を腐食させたり、冬季に凍結することで枠材の破損の原因になるなどの不都合を生じる。
本発明の格子体においては、下側の支持材の側面部は、交差面部から下方に向かって延出することになるため、下側の支持材に雨水等が浸入しにくく、また、雨水が浸入した場合でも、直ちに排出されるようになっている。また、上側の支持材の側面部は交差面部から上方に向かって延出することになるが、交差面部には、挿通孔が設けられているために、支持材に浸入した雨水等は挿通孔から排出されるようになっている。従って、本発明の格子体では、支持材内部に水が溜まりにくいので、腐食や凍結による破損を防止することができ、耐久性を確保することができる。
【００１２】
一方、本発明の面格子では、前記したいずれかの格子体と、前記格子体を構成する２本の支持材に取り付けた壁固定用のブラケットとを備えたことを特徴とする。
このような本発明によれば、当該面格子において前述した各効果と同様の効果を奏することができる。また、壁固定用のブラケットを介して支持材を壁に固定することができるので、支持材同士を連結する枠材等が不要で、部品点数を削減することができる。
【００１３】
【発明の実施の形態】
〔第１実施形態〕
以下、本発明の第１実施形態を図面に基づいて説明する。
図１ないし図４に、本実施形態に係る格子体を用いた面格子１０を示す。図１は、面格子１０が設けられた開口部を示す横断面図である。図２は、面格子１０の取付部分を拡大して示す分解斜視図である。図３および図４は、それぞれ面格子１０の要部を示す斜視図および縦断面図である。
【００１４】
面格子１０は、図１に示すように、例えば、住宅等の外壁１に設けられた開口部２における防犯性を確保するために、開口部２の室外側に取り付けられている。外壁１は、躯体としての柱３の室内外側にそれぞれ固定された内装材４や、外装材５から構成されている。また、図示を省略するが、内装材４および外装材５の間には、適宜な断熱材や防水材等が介装されている。開口部２は、見付け形状が矩形状の窓であって、室内側に窓台６や額縁７が設けられ、これらの窓台６、額縁７の室外側に窓枠８が固定されている。窓枠８は、上枠、下枠、および左右の縦枠を四周枠組みして形成されており、窓台６、額縁７、および柱３にビス止め等で固定されている。そして、窓枠８には、図示しない障子が取り付けられており、この障子が引き違い形式のものであれば、開口部２は、引き違い窓として開閉可能に構成されることとなる。
【００１５】
面格子１０は、開口部２の上下辺に沿って略水平に延びる２本の支持材としての横材１１と、これらの横材１１間に渡って上下に延び、横材１１の長手方向に沿って複数並べられた桟材としての縦桟１２と、横材１１の両端に固定された壁固定用のブラケット１３とを備えて構成されている。これらの横材１１、縦桟１２、およびブラケット１３は、ＳＵＳ製の板材から曲げ加工により形成されている。そして、外装材５を貫通して柱３にねじ止めされるビス１４でブラケット１３を固定することで、面格子１０は、外壁１に強固に固定されている。
【００１６】
横材１１は、図２ないし図４に示すように、長尺棒状で断面略ｅ字形に形成されており、上下の横材１１は、互いに上下対称形状となるように配置されている。上下の横材１１の対向面、すなわち、上側の横材１１における下面、および下側の横材１１における上面は、それぞれ縦桟１２と略直交する交差面部１１１になっている。この交差面部１１１には、複数の縦桟１２に対応して、これらの縦桟１２が挿通される挿通孔１１２が、打抜き加工により穿設されている。これらの挿通孔１１２は、断面略角形筒状の縦桟１２をがたつきなく挿通可能な大きさの角穴となっている。そして、挿通孔１１２には、面格子１０の内側から外側、すなわち、上側の横材１１における下方から上方、および下側の横材１１における上方から下方に向かって、縦桟１２が挿通されている。
【００１７】
横材１１の一方側である室内側には、交差面部１１１の室内側端縁に連続し、縦桟１２の先端が位置する側、すなわち、上側の横材１１における上方、および下側の横材１１における下方に向かって延出する、一方側の側面部としての第１側面部１１３が形成されている。この第１側面部１１３は、交差面部１１１と略直交して、縦桟１２と略平行に延びており、第１側面部１１３の延出方向先端側で、当該横材１１の高さ方向略中間位置には、交差面部１１１と略平行に、縦桟１２に向かって折り曲げられた折曲部１１３Ａが形成されている。そして、この折曲部１１３Ａの先端縁は、縦桟１２の側面に当接するとともに、交差面部１１１の反対側において折曲部１１３Ａと縦桟１２の側面とが溶接によりに固定されている。すなわち、上側の横材１１における折曲部１１３Ａの上側と、下側の横材１１における折曲部１１３Ａの下側とが、縦桟１２の側面に溶接、固定されている。
【００１８】
横材１１の他方側である室外側には、交差面部１１１の室外側端縁に連続し、縦桟１２の先端が位置する側に向かって延出する、他方側の側面部としての第２側面部１１４が形成されている。この第２側面部１１４は、交差面部１１１と略直交して、縦桟１２と略平行に延びており、当該横材１１における室外側の側面が第２側面部１１４で形成されている。第２側面部１１４の先端、すなわち、上側の横材１１における上端、および下側の横材１１における下端は、それぞれ室内側に向かって折り曲げられ、交差面部１１１と略平行に延びる外面部１１５が形成されている。そして、この外面部１１５の内側には、縦桟１２の先端が当接している、すなわち、上側の横材１１における外面部１１５により縦桟１２の上端が覆われ、下側の横材１１における外面部１１５により縦桟１２の下端が覆われている。
【００１９】
ブラケット１３は、図２に示すように、室内外方向に延びる取付部１３１と、外壁１の壁面に沿った固定部１３２とを備え、全体略Ｌ字形に形成されている。取付部１３１は、断面略Ｃ字形のチャンネル材状に形成され、かつ先端部が横材１１に向かって折り曲げられており、横材１１の交差面部１１１、第２側面部１１４、および外面部１１５の三方を囲んで、横材１１の端部を嵌合可能に形成されている。そして、取付部１３１に横材１１の端部を嵌合した状態で、これらを互いに溶接することで、横材１１にブラケット１３が固定されている。ブラケット１３の固定部１３２には、２箇所のビス孔が設けられ、これらのビス孔を通して２本のビス１４により、外壁１にビス止め固定されるようになっている。
【００２０】
ビス１４は、頭部に設けられた締め付け用の穴が角穴形状を有したタイプのもので、例えば、コードレックス（商品名）ビスが採用されている。このようなタイプのビス１４では、四角柱状の先端形状を有する専用工具（ビット）を用いて締め付け、および取り外し作業が実施され、通常のプラスやマイナスのスクリュードライバでは、取り外せないようになっている。また、ビス１４を外壁１に締め付け固定した後、頭部の締め付け用角穴には、ロウが埋められ、さらに取り外すことが困難になっている。ビス１４を取り外す際には、バーナー等でビス１４の頭部を加熱し、ロウを溶かした後に、専用工具を用いて取り外し作業を実施することとなる。
なお、ビス１４は、締め付け用の穴が角穴形状のものに限らず、締め付け用の穴がワンウェイ、すなわち、締め付け方向にビスを回転可能で、逆方向には回転不能な形状の締め付け用穴を有したタイプのビスを用いてもよい。また、ビス１４の頭部の締め付け用角穴を埋める材料としては、ロウに限らず、溶融可能な材料であればよく、例えば樹脂や金属等であってもよい。
【００２１】
次に、以上の構成を備える面格子１０の組み立て手順について説明する。
先ず、適宜な組み立て台の上に複数の縦桟１２を横にして所定ピッチで並べ、これらの縦桟１２の両端を挿通孔１１２に挿通して、外面部１１５の内側が縦桟１２の先端に当接するように横材１１をセットする。この際、縦桟１２は、その室外側となる側が下向きになるように並べられており、横材１１は、第１側面部１１３を上に向けて、挿通孔１１２の室内側縁と折曲部１１３Ａの端縁とが縦桟１２の側面に当接した状態でセットされている。これに続いて、横材１１の折曲部１１３Ａと縦桟１２の側面との交差部分を溶接により固定し、この溶接固定の作業を複数の縦桟１２について順次繰り返し実施する。このようにして、２本の横材１１と複数の縦桟１２とを固定した後に、横材１１の両端部にブラケット１３をセットし、これらを溶接により固定する。以上のようにして組み立てられた面格子１０を住宅等まで運搬し、外壁１の開口部２室外側にセットして、ビス１４を締め付けることで、外壁１に固定する。
【００２２】
以上のように外壁１に取り付けられた面格子１０では、室外側からの外観において、横材１１の第２側面部１１４、交差面部１１１、および外面部１１５が見えるが、第１側面部１１３や縦桟１２との固定部分である溶接ビードＷは、見えないようになっている。従って、横材１１は、あたかも、角柱状の部材であるかのように見え、この横材１１に縦桟１２が貫入して一体的に形成されたような外観を構成できるようになっている。また、面格子１０の室内側からの外観、すなわち、開口部２を通して室内から室外方向を見た場合には、図３に示すように、横材１１の交差面部１１１、および第１側面部１１３が見えるものの、折曲部１１３Ａや、縦桟１２との固定部分である溶接ビードＷは、見えないようになっている。
【００２３】
このような本実施形態によれば、次のような効果がある。
（１）横材１１の交差面部１１１に設けた挿通孔１１２に縦桟１２を挿通することで、縦桟１２と交差した横材１１の長手方向および直交方向について、縦桟１２を位置決め可能であるとともに、横材１１の第１側面部１１３の折曲部１１３Ａを縦桟１２の側面に当接することで、挿通孔１１２および折曲部１１３Ａの２箇所で縦桟１２と当接するため、横材１１に沿った軸線を中心とした回転方向についても、縦桟１２を位置決め可能である。従って、面格子１０の組み立てに際して、横材１１および縦桟１２が安定して位置決めされた状態で、溶接による固定作業を実施することができ、組立作業の作業効率向上を図ることができる。
【００２４】
（２）また、横材１１の室内側に形成された第１側面部１１３の折曲部１１３Ａを、縦桟１２の側面に固定することで、これらの固定部分である溶接ビードＷが室外側には表れず、室外側からの外観を良好にすることができる。
【００２５】
（３）さらに、第１側面部１１３の折曲部１１３Ａと縦桟１２の側面とを溶接、固定することで、固定部分である溶接ビードＷが、開口部２を通して室内側から見えず、室内側からの外観も良好にすることができる。
【００２６】
（４）また、横材１１において、挿通孔１１２が設けられた交差面部１１１の長手方向に沿った両側の端縁に第１、第２側面部１１３，１１４が連続して形成されているので、挿通孔１１２周辺の部材強度を確保できるため、室内に侵入を謀ろうとする者が挿通孔１１２部分から横材１１を破壊しづらくし、防犯性を高めることができる。
【００２７】
（５）また、横材１１の第２側面部１１４に連続して、室内側に折り曲げられ、縦桟１２の先端が当接する外面部１１５を形成することで、縦桟１２の先端を横材１１で覆うことができ、縦桟１２の内部への雨水等の浸入を防止できる。さらに、面格子１０の組み立てに際して、横材１１の外面部１１５に縦桟１２の先端を当接することで、縦桟１２に沿った方向の位置決めが可能になり、組立作業の作業効率をさらに向上させることができる。
【００２８】
（６）さらに、面格子１０下側の横材１１の第１、第２側面部１１３，１１４は、交差面部１１１から下方に向かって延出ので、下側の横材１１に雨水等が浸入しにくく、また、雨水が浸入した場合でも、直ちに排出されるようになっている。また、上側の横材１１の第１、第２側面部１１３，１１４は交差面部１１１から上方に向かって延出することになるが、交差面部１１１には、挿通孔１１２が設けられているために、横材１１に浸入した雨水等は挿通孔１１２から排出されるようになっている。従って、横材１１内部に水が溜まりにくいので、腐食や凍結による破損を防止することができ、耐久性を確保することができる。
【００２９】
（７）また、上下の横材１１のいずれもが、縦桟１２に固定されるとともに、壁固定用のブラケット１３が横材１１の両端部に取り付けられているので、これらの横材１１同士を連結する枠材等を不要にできるとともに、ブラケット１３を介して外壁１に固定することができ、部品点数を削減することができる。さらに、２本の横材１１を同一部品から構成できるため、部品の共通化を図ることができるとともに、横材１１を上下対称に配置したので、外観のデザインを統一し、意匠性を向上させることができる。
【００３０】
〔第２実施形態〕
次に、本発明の第２実施形態を図５に基づいて説明する。
図５は、第２実施形態の面格子１０の要部を示す縦断面図である。本実施形態の面格子１０では、前述の第１実施形態と比較して、横材１１における第１側面部１１３の形態が相違し、その他の構成は同様である。以下、相違点について詳しく説明する。
【００３１】
図５に示した本実施形態の面格子１０では、横材１１の交差面部１１１から延出する第１側面部１１３の延出方向が第１実施形態と異なっている。すなわち、第１側面部１１３は、交差面部１１１に対して鋭角に折り曲げられ、縦桟１２の側面に近づく傾斜を有して延出している。そして、第１側面部１１３には、第１実施形態のような折曲部が形成されておらず、その先端縁が縦桟１２の側面に当接し、これら第１側面部１１３の先端縁と縦桟１２の側面とが溶接により固定されている。
このような構成の面格子１０の組み立て手順は、第１実施形態と略同様であり、挿通孔１１２および第１側面部１１３の先端縁の２箇所と、外面部１１５の内側で縦桟１２に対する位置決めがなされるようになっている。
【００３２】
このような本実施形態によれば、前述の（１）、（２）、（４）〜（７）の効果と合わせて次のような効果がある。
（８）横材１１を折り曲げ加工によって形成する際に、折り曲げ回数を少なくできるので、加工手間を軽減し、加工性を向上させることができる。
【００３３】
〔第３実施形態〕
次に、本発明の第３実施形態を図６に基づいて説明する。
図６は、第３実施形態の面格子１０の要部を示す縦断面図である。本実施形態の面格子１０では、前述の第１実施形態と比較して、横材１１における第１側面部１１３の形態が相違し、その他の構成は同様である。以下、相違点について詳しく説明する。
【００３４】
図６に示した本実施形態の面格子１０では、横材１１の第１側面部１１３の先端側が折り曲げられる形態が第１実施形態と異なっている。すなわち、第１側面部１１３は、交差面部１１１から縦桟１２と略平行に延出し、一旦、縦桟１２側に折れ曲がって縦桟１２の側面に当接するとともに、縦桟１２の側面に沿って折れ曲がり、さらに縦桟１２の側面に略直交して離れる方向に延びた凹状部１１３Ｂを有している。そして、この凹状部１１３Ｂの一部、すなわち、上側の横材１１におけ凹状部１１３Ｂの上側と、下側の横材１１における凹状部１１３Ｂの下側とが、縦桟１２の側面に溶接、固定されている。
このような構成の面格子１０の組み立て手順は、第１実施形態と略同様であり、挿通孔１１２および凹状部１１３Ｂの当接面の２箇所で縦桟１２に対する位置決めがなされるようになっている。
なお、本実施形態では、第１側面部１１３と縦桟１２の側面とが、溶接に限らず、凹状部１１３Ｂ側から縦桟１２の側面まで貫通するビス止めにより固定されてもよい。
【００３５】
このような本実施形態によれば、前述の（１）〜（７）の効果と合わせて次のような効果がある。
（９）横材１１の凹状部１１３Ｂからビス止めにより縦桟１２を固定することも可能であり、ビス止めにより固定すれば、必要に応じて縦桟１２を取り外すことができ、交換可能に構成することができる。
【００３６】
〔第４実施形態〕
次に、本発明の第４実施形態を図７に基づいて説明する。
図７は、第４実施形態の面格子１０の要部を示す縦断面図である。本実施形態の面格子１０では、前述の第１実施形態と比較して、横材１１の形態が相違し、その他の構成は同様である。以下、相違点について詳しく説明する。
【００３７】
図７に示した本実施形態の面格子１０では、横材１１の上下方向の長さ寸法が第１実施形態と異なっている。すなわち、第１、第２側面部１１３，１１４の延出寸法が長くなっており、第１側面部１１３の折曲部１１３Ａと外面部１１５との間隔部分の距離は第１実施形態と略同一となっている。このような、横材１１は、例えば、面格子１０の上下方向の寸法が大きく、横材１１と縦桟１２との固定強度を高めたい場合や、外観のデザイン上の要求から横材１１の上下方向の寸法を大きくする場合等に採用される。
このような構成の面格子１０の組み立て手順は、第１実施形態と略同様であり、挿通孔１１２および第１側面部１１３の折曲部１１３Ａの２箇所と、外面部１１５の内側で縦桟１２に対する位置決めがなされるようになっている。そして、挿通孔１１２と折曲部１１３Ａとの縦桟１２に沿った方向の距離が大きくなっているため、横材１１および縦桟１２の組み立て時における位置決めがより安定し、かつ、組み立て後の固定強度が高くなっている。
【００３８】
このような本実施形態によれば、前述の（１）〜（７）の効果と合わせて次のような効果がある。
（１０）挿通孔１１２と折曲部１１３Ａとの縦桟１２に沿った方向の距離が大きくなっているので、横材１１および縦桟１２をより安定して位置決めでき、組立作業の作業効率をさらに向上させることができる。さらに、横材１１および縦桟１２の固定強度を高めることができる。
【００３９】
（１１）横材１１の上下方向寸法を大きくしても、第１側面部１１３の折曲部１１３Ａと外面部１１５との間隔部分の距離は変わらず、室内側からの外観を損なわず、良好な外観を保持できる。
【００４０】
なお、本発明を実施するための最良の構成、方法などは、以上の記載で開示されているが、本発明は、これに限定されるものではない。
すなわち、本発明は、主に特定の実施の形態に関して特に図示され、かつ、説明されているが、以上述べた実施の形態に対し、本発明の技術的思想および目的の範囲から逸脱することなく、形状、材質、数量、その他の詳細な構成において、当業者が様々な変形を加えることができる。
【００４１】
例えば、前述の各実施形態では、面格子１０が住宅の外壁１に取り付けられるものとしたが、これに限らず、住宅以外の建物や工作物等に取り付けられてもよく、また、外壁以外の内壁や間仕切り壁、屋根等に取り付けられてもよい。
また、前述の各実施形態では、支持材を水平方向に延びる横材１１とし、桟材を上下方向に延びる縦桟１２としたが、これに限らず、支持材を縦方向に向けて配置してもよく、また、適宜傾斜を有して配置してもよい。また、２本の支持材は、互いに平行である必要はなく、互いに角度を有して配置されていてもよい。
【００４２】
また、前述の各実施形態では、横材１１、縦桟１２、およびブラケット１３をＳＵＳ製とし、曲げ加工により形成するものとしたが、これに限らず、アルミ製や鋼製、合成樹脂製等であってもよい。アルミ製であれば、各部材を押出形材から形成することもでき、このようにすることで、加工手間を軽減し、より低コストで製造できるようになる。
また、前述の各実施形態では、横材１１の第１側面部１１３と縦桟１２の側面とを、溶接またはビス止めにより固定したが、これに限らず、溶着や接着、圧着等により固定されてもよく、また、固定用金具等を用いて固定されてもよい。
【００４３】
また、前述の各実施形態では、横材１１の交差面部１１１と第１、第２側面部１１３，１１４とを互いに交差する平面として形成したが、これに限らず、各々の部分を曲面状に形成してもよく、例えば、横材を全体略円筒状に形成することもできる。
また、前述の各実施形態では、横材１１の外面部１１５に縦桟１２の先端が当接するものとしたが、これに限らず、所定の間隔だけ離れて設けられていてもよい。この際、組み立て時において、位置決めスペーサ等を用い、縦桟に沿った方向についての横材および縦桟の位置決めを実施することができる。
【００４４】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lattice body and a plane lattice using the lattice body.
[0002]
[Background Art]

[0004]
[Problems to be solved by the invention]
However, in the lattice body described in Patent Literature 1, since the members are not stable when welding and fixing the members only by inserting the vertical bars into the C-shaped openings of the frame members, the frame members and the vertical bars are connected to each other. It is necessary to temporarily fix in the positioned state, and there is a problem that the working efficiency of the assembling work is low.
Further, since the welded portions of the frame member and the vertical bar are exposed on both sides of the frame material inside and outside, there is also a problem that the design of the appearance of the lattice body is impaired.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a lattice body which can improve the work efficiency of an assembling operation and can improve the appearance, and a surface lattice using the lattice body.
[0006]
[Means for Solving the Problems]
The lattice body of the present invention is a lattice body including a pair of long support members provided at predetermined intervals and a plurality of crosspieces spanned between these support members, wherein each of the support members A cross-section having a plurality of insertion holes into which ends of the plurality of crosspieces are inserted, and extending from both side edges along the longitudinal direction of the cross-section in a direction away from other support members, respectively. And two side portions provided, wherein one of the two side portions is fixed by abutting a side surface of the crosspiece.
[0007]
According to the present invention, by inserting the crosspiece into the insertion hole provided in the crossing surface of the support, the crosspiece can be positioned in the longitudinal direction and the orthogonal direction of the support intersecting with the crosspiece. At the same time, by contacting one side surface of the support member with the side surface of the crosspiece, the support member comes into contact with the crosspiece at at least two places of the insertion hole and the side surface portion. Also, the crosspiece can be positioned. Therefore, when assembling the lattice, fixing work such as welding can be performed in a state where the support member and the crosspiece are stably positioned, and the work efficiency of the assembling work can be improved.
Also, by fixing the side surface portion formed on one side of the support material to the side surface of the crosspiece, for example, when both members are fixed by welding, a weld bead as a fixed portion is attached to the other side surface. Does not appear, and the appearance can be improved by setting the other side to the side more visible.
[0008]
Furthermore, since the side portions are continuously formed on both side edges of the intersection surface portion where the insertion hole is provided, the strength of the members around the insertion hole can be secured, so that a person who intends to intrude into the room has an insertion hole portion. It is possible to make it difficult to break the support material, and to improve the crime prevention. Further, in the conventional lattice body, the lower frame member and the vertical rail are not fixed, and a vertical frame member for connecting the upper and lower frame members is required. Since both of the support members are fixed to the crosspiece, a frame member for connecting these two support members can be eliminated, and the number of parts can be reduced. Further, in the lattice body of the present invention, since the two support members can be formed from the same component, the components can be shared.
[0009]
At this time, in the lattice body of the present invention, the one side portion has a bent portion that is substantially parallel to the intersection surface portion and is bent toward a side surface of the crosspiece. It is characterized by being in contact with the side of the material.
In such a configuration, the side portion formed on one side of the support member is bent toward the crosspiece, and this bent portion is abutted and fixed to the side surface of the crosspiece, so that the inside of the space between the two support members is fixed. Then, even from a position slightly distant from the lattice body, the fixed portion can be hidden from the bent portion so that the appearance can be further improved.
[0010]
Further, in the lattice body according to the present invention, the support member includes an outer surface portion formed continuously with the other side surface portion of the two side surface portions and arranged to face the intersection surface portion. The tip of the crosspiece is in contact with the crosspiece.
In such a configuration, by forming an outer surface portion where the tip of the crosspiece abuts on the side face formed on the other side of the support material, the tip of the crosspiece can be covered with the support material, For example, when the crosspiece is formed of a hollow pipe-shaped member, it is possible to prevent rainwater or the like from entering the inside of the crosspiece. In addition, by assembling the lattice body, by contacting the tip of the crosspiece with the outer surface of the support member, positioning in the direction along the crosspiece becomes possible, and the work efficiency of the assembling work can be further improved.
[0011]
Further, in the lattice body of the present invention, the two support members are vertically opposed to each other and are arranged substantially horizontally.
In such a configuration, by installing the two support members vertically and horizontally, it is possible to configure a general surface grid, handrail, fence, gate, etc., in which the crosspieces extend vertically. Since the support members are arranged vertically symmetrically, the appearance design can be unified, and the design can be improved.
In addition, in the conventional lattice body, if the upper and lower frame members are made common and the design is unified, the upper frame member can be turned upside down and arranged on the lower side. If the frame material is opened upward, it is difficult for the rainwater, etc., which has entered the inside of the frame material to be discharged, and this water will corrode the frame material or freeze in winter, causing damage to the frame material, etc. Causes inconvenience.
In the lattice body of the present invention, since the side portion of the lower support material extends downward from the intersection surface portion, rainwater or the like hardly enters the lower support material, and Even if it enters, it is immediately discharged. In addition, the side surface of the upper support material extends upward from the crossing surface portion, but since the crossing surface portion is provided with an insertion hole, rainwater or the like that has infiltrated the support material has an insertion hole. It is being discharged from. Therefore, in the lattice body of the present invention, since water does not easily accumulate inside the support material, damage due to corrosion or freezing can be prevented, and durability can be ensured.
[0012]
On the other hand, the surface lattice of the present invention is characterized by comprising any one of the lattices described above and a bracket for fixing the wall attached to two support members constituting the lattice.
According to the present invention, the same effects as those described above can be obtained in the surface grating. In addition, since the support member can be fixed to the wall via the wall fixing bracket, a frame member or the like for connecting the support members is unnecessary, and the number of components can be reduced.
[0013]

[0021]
Next, an assembling procedure of the surface grating 10 having the above configuration will be described.
First, a plurality of vertical rails 12 are arranged side by side at a predetermined pitch on an appropriate assembling table, and both ends of these vertical rails 12 are inserted into the insertion holes 112, and the inside of the outer surface portion 115 is The cross member 11 is set so as to be in contact with. At this time, the vertical rails 12 are arranged so that the side on the outdoor side faces downward, and the horizontal member 11 is bent with the first side surface portion 113 upward and the indoor side edge of the insertion hole 112. It is set in a state where the edge of the portion 113A is in contact with the side surface of the vertical rail 12. Subsequently, the intersection between the bent portion 113A of the horizontal member 11 and the side surface of the vertical bar 12 is fixed by welding, and this welding and fixing operation is repeatedly performed on the plurality of vertical bars 12 sequentially. After fixing the two cross members 11 and the plurality of vertical bars 12 in this way, the brackets 13 are set on both ends of the cross members 11 and fixed by welding. The screen grid 10 assembled as described above is transported to a house or the like, set on the outside of the opening 2 of the outer wall 1, and fixed to the outer wall 1 by tightening the screw 14.
[0022]
In the surface grid 10 attached to the outer wall 1 as described above, the second side surface portion 114, the crossing surface portion 111, and the outer surface portion 115 of the cross member 11 can be seen from the exterior side, but the first side surface portion 113 and The weld bead W, which is a fixed portion to the vertical bar 12, is not visible. Therefore, the cross member 11 looks as if it is a prism-shaped member, and the cross bar 11 can be configured such that the vertical bar 12 penetrates and is integrally formed. . In addition, when the exterior of the surface grid 10 is viewed from the indoor side, that is, when the outdoor lattice is viewed from the indoor through the opening 2, as shown in FIG. 3, as shown in FIG. Are visible, but the bent portion 113A and the weld bead W which is a fixed portion to the vertical beam 12 are not visible.
[0023]
According to this embodiment, the following effects can be obtained.
(1) The vertical bar 12 can be positioned in the longitudinal direction and the orthogonal direction of the horizontal member 11 intersecting with the vertical bar 12 by inserting the vertical bar 12 into the insertion hole 112 provided in the intersection surface portion 111 of the horizontal member 11. At the same time, by contacting the bent portion 113A of the first side surface portion 113 of the cross member 11 with the side surface of the vertical bar 12, the two portions of the insertion hole 112 and the bent portion 113A contact the vertical bar 12 so that The vertical rail 12 can also be positioned in the direction of rotation about the axis along the material 11. Therefore, when assembling the surface grid 10, the fixing work by welding can be performed in a state where the cross members 11 and the vertical bars 12 are stably positioned, and the work efficiency of the assembling work can be improved.
[0024]
(2) Further, by fixing the bent portion 113A of the first side surface portion 113 formed on the indoor side of the cross member 11 to the side surface of the vertical bar 12, the weld bead W, which is a fixed portion of these, is formed on the outdoor side. And the appearance from the outdoor side can be improved.
[0025]
(3) Further, by welding and fixing the bent portion 113A of the first side surface portion 113 and the side surface of the vertical rail 12, the weld bead W, which is a fixed portion, cannot be seen from the indoor side through the opening 2 and the room. The appearance from the inside can also be improved.
[0026]
(4) In the cross member 11, the first and second side portions 113 and 114 are formed continuously on both side edges along the longitudinal direction of the intersecting portion 111 where the insertion holes 112 are provided. Since the strength of the members around the insertion hole 112 can be ensured, it is difficult for a person who intends to invade the room to break the cross member 11 from the insertion hole 112 portion, and the security can be improved.
[0027]
(5) Further, by forming an outer surface portion 115 that is bent toward the interior of the room and is in contact with the tip of the vertical bar 12 continuously with the second side surface portion 114 of the horizontal member 11, the tip of the vertical bar 12 is connected to the horizontal member. 11 to prevent infiltration of rainwater or the like into the interior of the vertical rail 12. Further, when assembling the surface grid 10, the tip of the vertical bar 12 is brought into contact with the outer surface portion 115 of the horizontal member 11, thereby enabling positioning in the direction along the vertical bar 12, thereby further improving the work efficiency of the assembling work. Can be done.
[0028]
(6) Further, since the first and second side surfaces 113 and 114 of the horizontal member 11 below the surface grid 10 extend downward from the crossing surface portion 111, rainwater or the like infiltrates the lower horizontal member 11. In addition, even if rainwater enters, it is immediately drained. In addition, the first and second side surfaces 113 and 114 of the upper cross member 11 extend upward from the crossing surface portion 111, but the crossing surface portion 111 has the insertion hole 112. Meanwhile, rainwater or the like that has entered the cross member 11 is discharged from the insertion hole 112. Therefore, water hardly accumulates in the cross member 11, so that damage due to corrosion or freezing can be prevented, and durability can be ensured.
[0029]
(7) Since both the upper and lower cross members 11 are fixed to the vertical rails 12 and the brackets 13 for fixing the walls are attached to both ends of the cross members 11, the cross members 11 are connected to each other. Can be eliminated, and can be fixed to the outer wall 1 via the bracket 13, so that the number of parts can be reduced. Furthermore, since the two cross members 11 can be made of the same parts, the parts can be shared, and the cross members 11 are arranged symmetrically in the vertical direction, so that the appearance design is unified and the design is improved. be able to.

The surface grating 10 of the present embodiment is different from the above-described first embodiment in the form of the cross member 11, and the other configuration is the same. Hereinafter, the differences will be described in detail.
[0037]
In the surface grating 10 of the present embodiment shown in FIG. 7, the length of the cross member 11 in the vertical direction is different from that of the first embodiment. That is, the extension dimensions of the first and second side surfaces 113 and 114 are longer, and the distance between the bent portion 113A of the first side surface 113 and the outer surface 115 is substantially the same as in the first embodiment. It has become. Such a cross member 11 has, for example, a large dimension in the vertical direction of the surface grid 10 and is required to increase the fixing strength between the cross member 11 and the vertical bar 12, or because of a design requirement of the external appearance, It is used when the size in the vertical direction is increased.
The procedure for assembling the surface lattice 10 having such a configuration is substantially the same as that of the first embodiment, and the vertical grid is formed inside the insertion hole 112 and the bent portion 113A of the first side surface portion 113 and inside the outer surface portion 115. Positioning with respect to 12 is performed. Since the distance between the insertion hole 112 and the bent portion 113A in the direction along the vertical bar 12 is large, the positioning at the time of assembling the cross member 11 and the vertical bar 12 is more stable, and after the assembly. The fixing strength is high.
