Description

【０００１】
【発明の属する技術分野】
この発明は、例えば積層式書架や積層式倉庫等における階上フロア用の開孔床材等として好適に用いられる透かしパネルに関する。
【０００２】
【従来の技術】
図書館等の積層式書架においては、多数の鋼製開孔床材を敷設施工することによって、階上フロアを形成するものがある。
【０００３】
例えば実開平５−４７１３２号公報に開示される従来の鋼製開孔床材は、水平方向に所定の間隔おきに並列に配置された複数の桟部材を、串刺し状に貫通するように補強パイプが固定されるとともに、各桟部材の両端に沿って一対の側枠が固定されるものである。
【０００４】
このような開孔床材は、各桟部材と補強パイプとの固定や、各桟部材両端と側枠との固定を、面倒な溶接によって行うものであるため、組付作業が困難である。
【０００５】
そこで、側枠を各桟部材の両端部にねじ止めして、各桟部材を側枠により挟持して組み付けるようにした開孔床材が提案されている。
【０００６】
この開孔床材では、補強パイプを必要とせず、部品点数の削減を図ることができる上、補強パイプや側枠の溶接作業も必要なく、組付作業を簡単に行うことができる。
【０００７】
【発明が解決しようとする課題】
しかしながら、上記提案例の開孔床材では、各桟部材の両端部が側枠に固定されるだけで、中間部が支持されず自由な状態にあるため、その中間部に多大な局部荷重が加わると、桟部材に撓みや弾性変形が生じ、その撓み等が長期にわたると塑性変形してしまう恐れがあり、耐荷重性の向上が望まれるところである。
【０００８】
この発明は、上記の実情に鑑みてなされたもので、局部荷重等に十分対処できて、良好な耐荷重性を得ることができる開孔床材等の透かしパネルを提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記目的を達成するため、この発明は、複数の桟部材が所定の間隔おきに並列に配置されるとともに、各桟部材の両側端部に沿って一対の側枠が取り付けられる透かしパネルにおいて、隣り合う桟部材間にジョイントピースが介在され、前記ジョイントピースにおける前記隣り合う桟部材とそれぞれ対向する一面側及び他面側が、両桟部材の対向面にパネル厚み方向に係合された状態にそれぞれ取り付けられてなるものを要旨とするものである。
【００１０】
この発明の透かしパネルにおいて、例えば一部の桟部材に多大な局部荷重が加わって、桟部材が弾性変形しようとした際には、その変形応力がジョイントピースを介して隣り合う他の桟部材に伝わることにより、上記局部荷重を全ての桟部材に分散させて、パネル全体で均一に受け止めることができる。
【００１１】
本発明においては、前記隣り合う桟部材のうち一方の桟部材の対向面に、桟部材の長さ方向に沿ってピース挿着溝が形成される一方、前記ジョイントピースの一面側が、前記ピース挿着溝にスライド自在に挿着されてなる構成を採用するのが好ましい。
【００１２】
すなわち、この構成を採用する場合、ジョイントピースを桟部材に挿入するだけの簡単な作業で、ジョイントピースを桟部材に装着することができる。
【００１３】
また本発明においては、前記隣り合う桟部材のうち他方の桟部材の対向面に、桟部材の長さ方向に連続して延びる突出部が設けられ、前記突出部の先端が前記ピース挿着溝の内部に配置されてなる構成を採用するのが良い。
【００１４】
すなわち、この構成を採用する場合、隣り合う桟部材間における視線の透過が防止されて、優れた遮蔽性を得ることができる。
【００１５】
また本発明においては、前記突出部が断面山型形状に形成されるとともに、その突出部の両側斜面が、内側に凹むよう湾曲する断面円弧形状に形成され、前記ジョイントピースの他面側が前記突出部に適合状態に接合されてなる構成、又は、前記ピース挿着溝が、断面円弧形状に形成され、前記ジョイントピースの一面側が前記ピース挿着溝の内周面に適合状態に接合されてなる構成を採用するのが望ましい。
【００１６】
すなわち、これらの構成を採用する場合には、一部の桟部材に加わる荷重を、ジョイントピースを介して、より一層効率良く、隣り合う他の桟部材に分散させることができる。
【００１７】
【発明の実施の形態】
図１及び図２はこの発明の実施形態である透かしパネルが適用された開孔床材（１０）を示す図である。両図に示すように、この開孔床材（１０）は、水平方向に所定の間隔おきに並列に配置される複数の桟部材（２０）と、各桟部材（２０）の両側端部に沿って水平方向に延びるように配置される一対の側枠（３０）と、複数の桟部材（２０）の各間に配置されるジョイントピース（４０）とを基本的な構成として備えている。
【００１８】
図１ないし図６に示すように、桟部材（２０）は、アルミニウム又はその合金からなる押出成形品をもって構成されており、上下両端部に桟部材長さ方向に連続して延びる角チューブ形状の上側片（２１）及び下側片（２１）と、上下両側片（２１）（２１）間に架け渡されるように一体形成され、かつ桟部材長さ方向に連続して延びる断面山型形状の突出部（２５）と、上下両側片（２１）（２１）間に架け渡されるように一体形成され、かつ上記突出部（２５）に対し平行して桟部材長さ方向に連続して延びる断面円弧状の補強片（２４）とを有している。
【００１９】
また、山型形状の突出部（２５）は、末広がり状に形成され、両側斜面（２５ａ）が、内側に凹むよう湾曲する断面円弧形状に形成されている。更に桟部材（２０）の補強片（２４）側には、その補強片（２４）を溝内周壁し、かつ桟部材長さ方向に連続して延びるピース挿着溝（２４ａ）が形成されている。このピース挿着溝（２４ａ）の開口両側縁部、換言すれば上下両側片（２１）（２１）の一コーナー部には、桟部材長さ方向に長さ方向に連続する係合片（２１ａ）が、ピース挿着溝（２４ａ）の開口部両側部を閉塞する態様に形成されている。
【００２０】
また、突出部（２５）における先端部内側には、桟部材長さ方向に連続して延びる略円形の孔が形成されており、この略円形孔における両側端部の開口周縁部がねじ止め部（２６）として構成されている。
【００２１】
更に桟部材（２０）のチューブ状上下両側片（２１）（２１）における両側端部の開口部が、係合孔（２２）（２２）として構成されている。
【００２２】
図１ないし図５、図７に示すように、側枠（３０）は、所定の長さを有する略帯板状のアルミニウム成形品をもって構成されており、上下両側縁部が内側に折曲されて、折曲補強片（３１）（３１）が形成されている。更に側枠（３０）には、長さ方向に所定の間隔おきに、換言すれば上記桟部材（２０）の配列ピッチに対応して、上下両側の所要領域が床材（１０）に対し内側に切り起こされて係合突起（３２）が形成されている。
【００２３】
また側枠（３０）における係合突起（３２）の各間のうち、一つおきの間には、その高さ方向中間位置に、上記桟部材（２０）における両側端部のねじ止め部（２６）にそれぞれ対応して、ねじ挿通孔（３６）がそれぞれ形成されている。
【００２４】
一方、図１ないし図５、図８に示すように、ジョイントピース（４０）は、アルミニウム又はその合金からなるもので、一面側が上記桟部材（２０）のピース挿着溝（２４ａ）に適合状態に挿入し得る挿着部（４１）として構成されるとともに、その円弧状挿着部（４１）の上下両端部に、上記桟部材（２０）の係合片（２１ａ）に係合し得る係合凹部（４１ａ）が形成されている。
【００２５】
更にジョイントピース（４０）の他面側は、上記桟部材（２０）の突出部（２５）を適合状態に接合し得るＶ溝形状の接合部（４５）として構成されている。
【００２６】
本実施形態の開孔床材（１０）は、上記構成の桟部材（２０）、側枠（３０）及びジョイントピース（４０）が、以下のように組み付けられて形成される。
【００２７】
すなわち、桟部材（２０）のピース挿着溝（２５ａ）に、その端部開口部から、ジョイントピース（４０）の挿着部（４１）を挿入するとともに、桟部材（２０）の係合片（２１ａ）を、ジョイントピース（４０）の係合凹部（４１ａ）に係合して溝開口方向（桟部材配列方向）に抜止めした状態で、ジョイントピース（４０）をピース挿着溝（２４ａ）に沿ってスライドさせて、桟部材（２０）の所定位置、例えば床材（１０）の中心線上まで移動させる。
【００２８】
なお本発明においては、ピース挿着溝（２４ａ）におけるジョイントピース（４０）の固定位置に、凸部や凹部等の位置決め係合部を形成しておき、この係合部にジョイントピース（４０）を係合させることにより、ジョイントピース（４０）を所定位置に、簡単かつ正確に位置決めできるよう構成しても良い。
【００２９】
こうして全ての桟部材（２０）にジョイントピース（４０）を挿着した後、各桟部材（２０）の両側端部における上下の係合孔（２２）（２２）内に、桟部材（２０）の両側から、一対の側枠（３０）の係合突起（３２）をそれぞれ挿入して係合し、桟部材（２０）を側枠（３０）に仮固定し、複数の桟部材（２０）を一対の側枠（３０）間に所定のピッチ配列で精度良く位置決めした状態に保持する。このとき、各桟部材（２０）に挿着されたジョイントピース（４０）におけるＶ溝形状の接合部（４５）の内周面に、隣り合う桟部材（２０）の山型突出部（２５）が適合されて係合した状態で、複数の桟部材（２０）の各間にジョイントピース（４０）が配置される。
【００３０】
なお、この仮組状態においては、並列に配置された複数の桟部材（２０）のうち、一つおきの桟部材（２０）における両側端部のねじ止め部（２６）が、両側枠（３０）のねじ挿通孔（３６）に位置的に対応して配置される。
【００３１】
続いて、タッピングビス等のねじ（５０）を一対の側枠（３０）の各ねじ挿通孔（３６）に両側から挿入して、各桟部材（２０）のねじ止め部（２６）に締結固定する。こうして、所要の桟部材（２０）が一対の側枠（３０）に連結固定されることにより、ねじ止めされない桟部材（２０）も含め全ての桟部材（２０）が、一対の側枠（３０）に挟持されて固定され、本実施形態の開孔床材（１０）が組み付けられる。
【００３２】
なお、この組付状態においては、図３に示すように、各桟部材（２０）における突出部（２５）の先端が、隣り合う桟部材（２０）のピース挿着溝（２４ａ）の内部に配置されて、換言すれば隣り合う桟部材（２０）の上下両側片（２１）（２１）に水平方向に交わる態様に配置されて、開孔床材（１０）の表裏間における視線の透過が防止されて、優れた遮蔽性を得ることができる。同時に、隣り合う桟部材（２０）（２０）間には、床材表裏間を貫通する隙間が設けられて、良好な通気性及び採光性を得ることができる。
【００３３】
以上のように、本実施形態の開孔床材（１０）によれば、隣り合う桟部材（２０）同士が、ジョイントピース（４０）により連結されているため、桟部材（２０）に十分な強度を得ることができる。
【００３４】
すなわち、ジョイントピース（４０）が組み込まれていない状態において、一部の桟部材（２０）の中間部等に多大な局部荷重が加わると、桟部材（２０）は、その突出部（２５）が突出方向に膨出するように圧縮弾性変形したり、桟部材（２０）自体が下方に撓んだりして、これらの変形が悪影響を及ぼすものである。これに対し、本実施形態では、桟部材（２０）の各間にジョイントピース（４０）を介在させているため、桟部材（２０）の中間部に多大な局部荷重が加わって、桟部材（２０）が弾性変形しようとした際に、その変形応力がジョイントピース（４０）を介して隣り合う桟部材（２０）に順次伝わることにより、上記局部荷重が全ての桟部材（２０）に分散されて、桟部材（２０）全体、ひいては床材（４０）全体で局部荷重を受け止めることができる。このように局部的に応力が集中するのを回避できるので、桟部材（２０）の変形を最小限に抑制することができ、良好な耐荷重性を得ることができ、耐久性の向上等を図ることができる。
【００３５】
更に本実施形態においては、ジョイントピース（４０）における挿着部（４１）の外周面全域を、隣り合う一方の桟部材（２０）の挿着溝（２４ａ）に適合状態に接合させるとともに、ジョイントピース（４０）における接合部（４５）の全域を、隣り合う他方の桟部材（２０）の突出部（２５）に適合状態に接合させるものであるため、一部の桟部材（２０）に加わる局部荷重を、ジョイントピース（４０）を介して効率良く他の桟部材（２０）に伝えることができ、応力集中をより確実に回避でき、より一層耐荷重性を向上させることができる。
【００３６】
しかも、ジョイントピース（４０）における挿着部（４１）の外周面及び接合部（４５）の外周面や、桟部材（２０）における突出部（２５）の両側斜面（２５ａ）及び挿着溝（２４ａ）の内周面等の接合部を、円弧状に形成しているため、これらの接合領域によって、床材厚さ方向に加わる局部荷重を、より一層効率良く他の桟部材（２０）に分散させることができ、一段と耐荷重性を向上させることができる。
【００３７】
また、本実施形態においては、側枠（３０）の上下両側端部を折曲して折曲補強片（３１）（３１）を形成しているため、側枠（３０）自体の強度を向上できて、床材全体の強度及び耐荷重性を更に向上させることができる。
【００３８】
一方、本実施形態の開孔床材（１０）においては、桟部材（２０）にジョイントピース（４０）を挿着した後、側枠（３０）の係合突起（３２）を、桟部材（２０）の係合孔（２２）に嵌め込んで、桟部材（２０）及び側枠（３０）を仮止めするとともに、その仮止め状態で、桟部材（２０）を側枠（３０）にねじ止めして固定するものであるため、面倒な溶接作業も必要なく、簡単かつ位置精度良く組み付けることができるとともに、コストの削減を図ることができる。
【００３９】
また、本実施形態においては、桟部材（２０）を、上下両側片（２１）（２１）間に、突出部（２５）及び補強片（２４）を架け渡した構造とすることにより、全体としてチューブ状に形成されるため、床材（１０）として、より一層強度を向上させることができる。
【００４０】
更に本実施形態においては、桟部材（２０）、側枠（３０）及びジョイントピース（４０）として、鋼製のものに比べて、加工が容易なアルミニウム製のものを用いているため、桟部材（２０）や側枠（３０）等の部品の製作を簡単に行うことができる。特に桟部材（２０）は、押出成形によって形成するものであるため、効率良く生産することができる。
【００４１】
また、側枠（３０）の所要領域を切り起こして、係合突起（３２）を形成するものであるため、プレス成形等を用いて、係合突起（３２）を簡単に形成することができる。
【００４２】
また本実施形態においては、一つおきの桟部材（２０）を側枠（３０）の両側からねじ止めするものであるため、全ての桟部材（２０）をねじ止めする場合と比較して、ねじ止め作業を半減させることができ、より一層組付作業を容易に行うことができる。ここで、本実施形態では、一つおきの桟部材（２０）を側枠（３０）の両側からねじ止めすることにより、全ての桟部材（２０）が一対の側枠（３０）に挟持されて確実に固定されるため、組付強度を十分に確保することができる。
【００４３】
なお、上記実施形態においては、ジョイントピース（４０）として、桟部材（２０）の突出部（２５）にほぼ対応する大きさのものを用いているが、本発明においては、ジョイントピース（４０）の大きさは特に制限されることはなく、例えば図９に示すように、桟部材（２０）の突出部（２５）の先端部に対応する大きさのジョイントピース（４０）を用いても良い。更に、図１０に示すように、桟部材（２０）の上端から下端まで達する大きさのジョイントピース（４０）を用いるようにしても良く、同図のように大きいサイズのジョイントピース（４０）を用いる場合には、桟部材（２０）のひねり方向の変形を防止する効果が大きくなり、一段と強度を向上させることができる。
【００４４】
また本発明において、桟部材（２０）、側枠（３０）及びジョイントピース（４０）等の各構成部材の材質は、上記のアルミニウムに限定されるものではなく、アルミニウム以外の金属からなるものを用いても良く、特にジョイントピース（４０）としては、合成樹脂製のものを用いても良い。
【００４５】
また上記実施形態においては、桟部材（２０）の突出部（２５）先端を、隣り合う桟部材（２０）の挿着溝（２４ａ）内に配置して、開孔床材（１０）の表裏間における視線の透過を防止するようにしているが、本発明は、それだけに限られず、図１１に示すように、桟部材（２０）の突出部（２５）先端を、隣り合う桟部材（２０）の挿着溝（２４ａ）まで達しないように配置して、隣り合う桟部材（２０）間において、視線の透過を許容するような床材にも適用することができる。
【００４６】
また上記実施形態においては、隣り合う桟部材（２０）間において、床材中心線上に、一つずつジョイントピース（４０）を挿着するようにしているが、本発明はそれだけに限られず、隣り合う桟部材間に、２つ以上ジョイントピースを挿着しても良く、ジョイントピース（４０）を床材中心線から逸脱する位置に配置しても良い。
【００４７】
また上記実施形態においては、本発明の透かしパネルを、開孔床材に適用する場合について説明したが、それだけに限られず、本発明は、仕切パネルや、壁パネルの他、溝蓋パネル等、他のパネルにも適用することができる。
【００４８】
【発明の効果】
以上のように、この発明の透かしパネルによれば、隣り合う桟部材間にジョイントピースを介在させるものであるため、例えば一部の桟部材に多大な局部荷重が加わって、桟部材が弾性変形しようとした際には、その変形応力がジョイントピースを介して隣り合う桟部材に伝わることにより、上記局部荷重を、全ての桟部材に分散してパネル全体で受け止めることができるので、桟部材の変形を最小限に抑制することができ、良好な耐荷重性を得ることができるという効果がある。
【００４９】
本発明において、隣り合う桟部材の一方にピース挿入溝を形成し、その溝にジョイントピースを挿入するよう構成する場合には、ジョイントピースを、挿入作業によって簡単に桟部材に装着することができ、パネル組立作業を簡単に行うことができるという利点がある。
【００５０】
また本発明において、桟部材の突出部先端を、隣り合う桟部材のピース挿着溝の内部に配置する場合には、隣り合う桟部材間における視線の透過が防止されて、優れた遮蔽性を得ることができるという利点がある。
【００５１】
また本発明において、桟部材における山型突出部の両側斜面を円弧状に形成したり、あるいはピース挿着溝の内周面を円弧状に形成する場合には、一部の桟部材に加わる局部荷重を、ジョイントピースによって、より一層効率良く他の桟部材に分散させることができ、一段と耐荷重性を向上させることができるという利点がある。

BACKGROUND OF THE INVENTION
The present invention relates to a watermark panel that is suitably used as, for example, a perforated floor material for an upper floor in a stacked book rack, a stacked warehouse, or the like.
[0002]
[Prior art]
Some stacked bookshelves such as libraries form an upper floor by laying and constructing a large number of steel perforated flooring materials.
[0003]
For example, a conventional steel perforated floor material disclosed in Japanese Utility Model Laid-Open No. 5-47132 is a reinforcement pipe so as to penetrate a plurality of crosspiece members arranged in parallel at predetermined intervals in a horizontal direction in a skewered manner. Is fixed, and a pair of side frames are fixed along both ends of each crosspiece member.
[0004]
Such a perforated floor material is difficult to assemble because the crosspiece member and the reinforcing pipe are fixed to each other and the crosspiece member both ends and the side frame are fixed by troublesome welding.
[0005]
In view of this, a perforated floor material has been proposed in which the side frames are screwed to both ends of each cross member, and the cross members are sandwiched and assembled by the side frames.
[0006]
In this perforated floor material, a reinforcing pipe is not required, the number of parts can be reduced, and welding work for the reinforcing pipe and the side frame is not required, and the assembling work can be easily performed.
[0007]
[Problems to be solved by the invention]
However, in the perforated floor material of the above proposed example, since both ends of each crosspiece member are fixed to the side frame and the intermediate portion is not supported and is in a free state, a large local load is applied to the intermediate portion. If added, the crosspiece member will bend and elastically deform, and if the bend or the like is prolonged, it may be plastically deformed, and an improvement in load resistance is desired.
[0008]
The present invention has been made in view of the above circumstances, and an object thereof is to provide a watermark panel such as a perforated floor material that can sufficiently cope with a local load and the like and can obtain a good load resistance. .
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a watermark panel in which a plurality of crosspieces are arranged in parallel at predetermined intervals and a pair of side frames are attached along both side ends of each crosspiece. A joint piece is interposed between the crosspieces, and one side and the other side of the jointpiece facing the adjacent crosspieces are respectively engaged with the opposite faces of both crosspieces in the panel thickness direction. The gist of what is made is.
[0010]
In the watermark panel of the present invention, for example, when a large local load is applied to some of the crosspiece members and the crosspiece member tries to elastically deform, the deformation stress is applied to the other crosspiece members adjacent to each other via the joint piece. By being transmitted, the above-mentioned local load can be distributed to all the crosspiece members and can be received uniformly throughout the panel.
[0011]
In the present invention, a piece insertion groove is formed along the length direction of the crosspiece member on the opposing surface of one of the adjacent crosspiece members, while one side of the joint piece is connected to the piece insertion piece. It is preferable to adopt a configuration in which the groove is slidably inserted into the groove.
[0012]
That is, when this configuration is adopted, the joint piece can be attached to the crosspiece member by a simple operation of simply inserting the jointpiece into the crosspiece member.
[0013]
Further, in the present invention, a protruding portion that extends continuously in the length direction of the crosspiece member is provided on the opposing surface of the other crosspiece member among the adjacent crosspiece members, and the tip of the protruding portion is the piece insertion groove It is preferable to adopt a configuration that is arranged in the interior of the housing.
[0014]
That is, when this configuration is adopted, the transmission of the line of sight between adjacent crosspiece members is prevented, and excellent shielding properties can be obtained.
[0015]
Further, in the present invention, the projecting portion is formed in a cross-sectional mountain shape, and both side slopes of the projecting portion are formed in a circular arc shape that curves so as to be recessed inward, and the other surface side of the joint piece is projected. Or the piece insertion groove is formed in an arc shape in cross section, and one surface side of the joint piece is joined to the inner peripheral surface of the piece insertion groove in a conforming state. It is desirable to adopt a configuration.
[0016]
That is, when these structures are employed, the load applied to some of the crosspiece members can be more efficiently distributed to the other adjacent crosspiece members via the joint piece.
[0017]

Yes. Engagement pieces (21a) that are continuous in the longitudinal direction in the length direction of the crosspiece member are formed at the edges on both sides of the opening of the piece insertion groove (24a), in other words, at one corner of the upper and lower side pieces (21) (21). ) Is formed so as to close both sides of the opening of the piece insertion groove (24a).
[0020]
Further, a substantially circular hole extending continuously in the length direction of the crosspiece member is formed on the inner side of the tip of the protrusion (25). (26).
[0021]
Furthermore, the opening part of the both-sides edge part in the tube-like upper and lower both-side piece (21) (21) of a crosspiece member (20) is comprised as an engagement hole (22) (22).
