Description

【０００１】
【発明の属する技術分野】
本発明は、土間ユニット構造及び土間ユニットの施工方法に係り、特に、勝手口、玄関等の住宅の土間を形成する土間ユニット構造及び土間ユニットの施工方法に関する。
【０００２】
【従来技術】
従来、パネル構法等の、床をパネルにより形成して住宅を構築する場合において、住宅の勝手口や玄関等のいわゆる土間は、施工現場においてコンクリートにより住宅の基礎を構築する場合に、同時にコンクリートを打設すると共に、当該土間を画成する床パネルの側端部に、夫々、側板を固定することにより形成していた。
【０００３】
しかしながら、このように施工現場において、その都度、コンクリートを打設すると共に、床パネルの端部に側板を固定することにより土間を形成することとした場合には、施工現場における施工作業が極めて煩雑であると共に、コンクリートの養生期間を必要とし、作成に時間が掛かる、という不具合が存していた。
【０００４】
【発明が解決しようとする課題】
そこで、請求項１記載の発明の技術的課題は、パネルにより床を形成して構築する住宅の土間を容易かつ迅速に作成することにある。さらに、この請求項１記載の発明の技術的課題は、上述した技術的課題に加えて、床パネルの寸法と同一に形成され、より容易に土間用空隙内にはめ込まれる土間ユニットを提供することにある。
【０００５】
請求項２記載の発明の技術的課題は、上記の請求項１記載の発明の技術的課題に加えて、軽量であると共に剛性が高く、容易に成形でき、かつ、耐久性に富む土間ユニットを提供することにある。
また、請求項３記載の発明の技術的課題は、パネルにより床を形成して構築する住宅の土間を容易かつ迅速に作成するための土間ユニットの施工方法を提供することにある。
【０００６】
【課題を解決するための手段】
このような技術的課題解決のため、請求項１記載の発明にあっては、床がパネル１０により形成される住宅において、第１の床パネル２３及びこの第１の床パネル２３の側方に配置される第２、第３の床パネル２４，２５によって画成される土間用の空隙１１にはめ込まれると共に、前記床パネル１０（２３，２４，２５）を支持する基礎部１２により支持され、前記床パネル１０により形成される床面１３よりも低く配置される踏み板部１４と、この踏み板部１４の周縁に立設され、前記土間用の空隙１１を画成する床パネル１０の端部を覆う側板部４３，４４，４５とが形成される土間ユニット１５を備え、前記土間ユニット１５は、上方及び側方の一面部が開放された直方体箱状に形成された土間ユニット本体部１８と、この土間ユニット本体部１８の外側面部に設けられた係止部１９とにより構成され、幅寸法Ｌは、前記土間用空隙１１を後方から画成する第１の床パネル２３の寸法Ｌ１と同一に形成されると共に、長さ寸法Ｌ２は、当該第１の床パネル２３の端部から布基礎１７までの間隔寸法Ｌ３と同一に形成されることにより、後端部が床パネル２３を支持する床受け材１６上に載置されると共に、前端部が布基礎１７により支持されており、前記係止部１９は、側方係止部２０と後方係止部２１とからなり、これらの側方及び後方係止部２０，２１の厚さ寸法は前記床パネル２３，２４，２５と同一に形成され、
前記布基礎１７には前記土間ユニット本体部１８を収納可能に形成された凹部２２が設けられると共に、布基礎１７上に載置されて前記土間用の空隙１１を側方から画成する第２及び第３の床パネル２４，２５の側端部２６，２６と前記凹部２２との間には、前記側方係止部２０，２０が係止される係合段部２７が形成されており、前記床受け材１６上に載置されて前記土間用の空隙１１を後方から画成する第１の床パネル２３と床受け材１６端部の間には、土間ユニット１５の後方係止部２１を係止する係合段部２９が形成されていることを特徴とする。
【０００７】
従って、請求項１に記載された発明にあっては、住宅の基礎部１２が構築され、その後、基礎部１２上に床パネル１０（２３，２４，２５）が敷設された場合には、住宅の土間用の空隙１１内に土間ユニット１５を基礎部１２により支持させて固定させる。このようにして土間ユニット１５が使用された場合には、床パネル１０よりも低く配置される踏み板部１４と、土間用の空隙１１を画成する床パネル１０の端部を覆う側板部４３，４４，４５とを有する土間が形成される。
【０００８】
その結果、請求項１記載の発明にあっては、従来のようにコンクリートを打ち込み、その後、養生させると共に、床パネルの端部に側板部を固定して土間を形成する必要はなく、土間ユニット１５を基礎部１２上に支持させて土間用の空隙１１内にはめ込むだけで、容易かつ迅速に住宅の土間を形成することができる。
【０００９】
また、この請求項１記載の発明にあっては、上記土間ユニット１５を土間用空隙１１内に配置する場合には、土間ユニット１５の前端部を布基礎１７上に載置させると共に、後端部を床受け材１６上に載置させることにより、土間用空隙１１内に配置されるものである。
【００１０】
さらに、この請求項１記載の発明にあっては、上記土間ユニット１５は、幅寸法Ｌが、土間の空隙１１を後方から画成する床パネル材２３の幅寸法Ｌ１と同一に形成されると共に、長さ寸法Ｌ２は、当該床パネル材２３の端部から布基礎１７までの間隔寸法Ｌ３と同一に形成されているため、土間ユニット１５を土間用の空隙１１内に、土間用の空隙１１の寸法と完全に幅寸法及び長さ寸法を一致させてはめ込むことができる。
【００１１】
また、上記土間ユニット１５は、布基礎１７に形成された凹部２２内に土間ユニット本体部１８が収納され、布基礎１７上に形成された係合段部２７，２７に側方係止部２０，２０が配置されると共に床受け材１６上に形成された係合段部２９に後方側係止部２１が、夫々、係合されて配置されている。従って、この請求項１記載の発明にあっては、上記の効果に加えて、土間ユニット１５を、土間用空隙１１の大きさに完全に一致させた形で、他の部材を一切介在させることなく、土間用空隙１１内により容易に配置させることができる。
【００１２】
請求項２記載の発明にあっては、上記土間ユニット本体部１８のフレームは、繊維強化プラスチックにより形成されていることを特徴とする。
従って、請求項２記載の発明にあっては、土間ユニット１５の土間ユニット本体部１８のフレーム３７を一体成形により作成して土間ユニット１５を作製することができる。
【００１３】
その結果、請求項２記載の発明にあっては、土間ユニット本体部１８のフレーム３７を合成樹脂による一体成形により作成することができるため、請求項１記載の発明の効果に加えて、容易かつ迅速に、土間ユニット１５を形成することができる。また、このような請求項２記載の発明により、土間ユニット１５が形成された場合には、土間ユニット１５の土間ユニット本体部１８のフレーム３７は、繊維強化プラスチックにより形成されていることから、全体が木製の場合よりも軽量に形成され、搬送及び施工の際の取り扱いが容易となる。
【００１４】
また、繊維強化プラスチックにより形成されていることから、軽量でありながら剛性が高いため、長年に亘り、使用された場合であっても耐久性に富み、使用により破損等が発生することがない。
請求項３記載の発明にあっては、上述した請求項１または請求項２記載の発明による土間ユニット１５の施工方法であって、隣接する２つ（第１及び第３）の床パネル２３，２５が敷き込まれた後、当該土間ユニット１５を設置し、その後、残る一辺を形成する第２の床パネル２４を敷き込み、土間ユニット１５の周囲３辺を囲った後、土間ユニット１５の係止部１９と床パネル端部２６を接合することを特徴とする。
【００１５】
従って、請求項３記載の発明にあっては、土間を形成する場合には、先ず、隣接している第１及び第３の床パネル２３，２５を敷き込んで、土間ユニット１５を設置し、土間ユニット１５の残る一辺を形成する第２の床パネル２４を敷き込んで土間ユニット１５の周囲を覆い、土間ユニット１５の係止部１９と床パネル端部２６とを接合するものである。
【００１６】
その結果、請求項３記載の発明にあっては、従来のようにコンクリートを打ち込み、その後、養生させると共に、床パネルの端部に側板部を固定して土間を形成する必要はなく、土間ユニット１５を基礎部１２上に支持させて土間用の空隙１１内にはめ込むだけで、容易かつ迅速に住宅の土間を形成することができる。
【００１７】

【００２０】
そして、上記床パネル材２３の端部は、支持部材３４により地面に支持固定された床受け材１６上に載置されて固定されている。また、上記２枚の床パネル材２４，２５は、この床受け材１６上に載置されて固定されていると共に、端部は、布基礎１７上に載置されて固定されている。
一方、上記土間ユニット１５は、上方及び側方の一面部が開放された直方体箱状に形成された土間ユニット本体部１８と、この土間ユニット本体部１８の外側面部に設けられた係止部１９とにより構成されている。
【００２１】
上記土間ユニット本体部１８は、繊維強化プラスチック製の箱状のフレーム３７と、このフレーム３７の下面に接合された底面板３３とを有する。上記フレーム３７は底板部４０と、この底板部４０の３辺部において立設された３つの側板部４３，４４，４５とを備えている。そして、これらの側板部４３，４４，４５の上縁部は外方へ突出する折曲部４２が設けられており、上記底板部３３は底板部４０の裏面に接合され、補強板としての役割を果たす。また、上記折曲部４２の厚さ寸法は、図２に示すように、フローリング材３２の厚さ寸法と同一に形成されている。
【００２２】
また、図２に示すように、この底面板３３とフレーム３７とは、ユニットの側面部に複数個取り付けられた固定金具３５に、ビス等の適宜の固定手段により固定されている。この固定金具３５は、断面クランク状に形成され、上下一対の折曲片３８，３９を有している。この下方の折曲片３８上には上記底面板３３の端部が固定されており、上方の折曲片３９には上記係止部１９が固定されている。
【００２３】
この係止部１９は、側方係止部２０，２０と、これらの側方係止部２０，２０に連設された後方係止部２１とからなり、その厚さ寸法は床パネル材２３，２４，２５の厚さ寸法と同一に形成されている。
また、これらの側方係止部２０，２０及び後方係止部２１は、上記折曲部４２と固定金具３５の折曲片３９との間に配設され、ビス等の適宜の固定手段により上記折曲片３９に固定されてフレーム３７の側板部４３，４４，４５に取付られている。
【００２４】
そして、本実施の形態にあっては、上記土間ユニット１５の幅寸法Ｌは、土間の土間用空隙１１を後方から画成する床パネル材２３の幅寸法Ｌ１と同一に形成されると共に、長さ寸法Ｌ２は、当該床パネル材２３の端部から布基礎までの間隔寸法Ｌ３と同一に形成されている。
また、上記布基礎１７には上記土間ユニット本体部１８を収納可能に形成された凹部２２が設けられていると共に、布基礎１７上に載置され、上記土間用の空隙１１を側方から画成する床パネル材２４，２５の側端部２６，２６と上記凹部２２との間には、上記側方係止部２０，２０が載置されうる係合段部２７，２７が形成されている。
【００２５】
そして、上記土間ユニット１５の高さ寸法Ｌ４は、上記床パネル材２４，２５の表面部と布基礎１７に形成された凹部２２の底面部との間の間隔寸法Ｌ５と同一に形成されている。
また、上記床受け材１６上に載置された、土間用の空隙１１を後方から画成する床パネル材２３と床受け材の端部２８の間には、土間ユニット１５の後方係止部２１が係止されうる係合段部２９が形成されている。
【００２６】
なお、布基礎１７の前面部には、勝手口の踏み石３６が形成されている。
以下、本実施の形態に係る土間ユニット構造及び土間ユニット施工方法の作用について説明する。
本実施の形態に係る土間ユニット構造により土間を形成する場合には、住宅の基礎部１２を形成するコンクリート製の布基礎１７が構築されると共に、地面上に支持部材３４により支持された床受け材１６が配設され、布基礎１７及び床受け材１６上に床パネル１０を敷設する際に、同時に土間を形成することができる。
【００２７】
即ち、床パネル材２３、２４，２５により画成された、勝手口を形成する土間用空隙１１内に、予め工場にて作成され、当該住宅施工現場へ各種パネル材と共に運搬された土間ユニット１５を配設することにより土間を形成する。
この際の施工手順は、先ず、２枚の隣接する側方の床パネル２３及び後方の床パネル２５を敷き込んだ後、上記土間ユニット１５を設置し、その後、残る一辺の側方の床パネル２４を敷き込み、土間ユニット１５の周囲３辺を囲った後、土間ユニット１５の係止部１９と床パネル端部２６を接合する。
【００２８】
この場合、上述のように、本実施の形態にあっては、上記土間ユニット１５の幅寸法Ｌは、土間用空隙１１を後方から画成する床パネル材２３の幅寸法Ｌ１と同一に形成されると共に、長さ寸法Ｌ２は、当該床パネル材２３の前端から布基礎１７の外方端縁までの間隔寸法Ｌ３と同一に形成され、また、上記布基礎１７には上記土間ユニット本体部１８を収納可能に形成された凹部２２が設けられていると共に、布基礎１７上に載置され、上記土間用の空隙１１を側方から画成する床パネル材２４，２５の側端部２６，２６と上記凹部２２との間には、上記側方係止部２０，２０が載置されうる係合段部２７，２７が形成されており、更に、上記底板部３３と側方係止部２０の上端縁との間の間隔寸法Ｌ４は、上記床パネル材２４，２５の表面部と布基礎１７に形成された凹部２２の底面部との間の間隔寸法Ｌ５と同一に形成されている。
【００２９】
その結果、土間ユニット１５は、上記底板部３３の前端部は布基礎１７に形成された凹部２２内に収納され、側方係止部２０，２０は、夫々、係合段部２７，２７に係合すると共に、後方係止部２１は床受け材１６と床パネル材２３とにより形成される係合段部２９に係合し、土間用空隙１１の上部を覆った形で完全にはまり込む。
【００３０】
この場合、底板部３３と側方係止部２０，２０の上端縁との間の間隔寸法Ｌ４は、上記床パネル材２４，２５の表面部と布基礎１７に形成された凹部２２の底面部との間の間隔寸法Ｌ５と同一に形成されているため、土間ユニット１５が土間用空隙１１内に配置された場合には、図２に示すように、後方係止部２１の上面部は、夫々、床パネル材２３の上面部と同一面上に配置されると共に、側方係止部２０，２０の上面部は、夫々、床パネル材２４，２５の上面部と同一面上に配置されることとなり、わずかに折曲部４２のみが上方へ突出することとなる。
【００３１】
そして、図２に示すように、土間ユニット１５は、互いに隣接する後方係止部２１と床パネル材２３、一方の側方係止部２０と床パネル材２４、他方の側方係止部２０と床パネル材２５とをスクリュー釘３０，３１により、床パネル材２３，２４，２５側と係止部１９側の双方向から互いに交差するように打ち込んで固定する。
【００３２】
その後、床パネル１０上にフローリング材３２を敷設する場合には、図２に示すように、フローリング材３２の端部を上記折曲部４２に当接させて敷設する。この場合、上述のように、フローリング材３２の厚さ寸法と折曲部４２の高さ寸法とは同一に形成されているため、折曲部４２とフローリング材３２の表面とは同一面となる。
【００３３】
このようにして土間ユニット１５が土間用空隙１１内に固定された場合には、土間ユニット１５は、底板部３３の前端部が布基礎１７の凹部２２により支持され、側方係止部２０，２０の前端部が、布基礎１７により形成される係合段部２７，２７により支持され、また、側方係止部２０，２０の後端部及び後方係止部２１が、床受け材１６により形成される係合段部２９により支持されることとなる。
【００３４】
その結果、床パネル２３，２４，２５により形成される床面１３よりも低い踏み板部１４と、この踏み板部１４の周縁に立設され、土間用の空隙１１を画成する床パネル２３，２４，２５の端部を夫々覆う側板部４３，４４，４５とを有する土間が形成される。また、上述のように、所定の厚さ寸法を有する底板部３３が設けられており、居住者が土間ユニット１５上に乗った場合であっても、荷重は上記底板部３３を介して布基礎１７及び床受け材１６により支持される。
従って、本実施例に係る土間ユニット構造にあっては、住宅の勝手口の土間を形成する場合に、従来のようにコンクリートを打ち込み、その後、養生させると共に、土間を画成する床パネル材の端部に側板を固定して土間を形成する必要はなく、土間ユニット１５を布基礎１７及び床受け材１６上に支持させて土間用空隙１１内にはめ込むだけで、容易かつ迅速に住宅の勝手口の土間を形成することができる。
【００３５】
また、本実施の形態に係る土間ユニット構造及び土間ユニットの施工方法にあっては、上記土間ユニット１５は、幅寸法Ｌは、土間用空隙１１を後方から画成する床パネル材２３の幅寸法Ｌ１と同一に形成されると共に、長さ寸法Ｌ２は、当該床パネル材の２３の端部から布基礎１７の外方端縁までの間隔寸法Ｌ３と同一に形成されているため、他の固定部材等を一切介することなく、土間ユニット１５を土間用空隙１１内に、土間用空隙１１の寸法と完全に幅寸法及び長さ寸法を一致させてはめ込み、布基礎１７上に形成された係合段部２７，２７に側方係止部２０，２０を配置すると共に床受け材１６上に形成された係合段部２９に後方側係止部２１を、夫々、係合させ、スクリュー釘３０，３１のみにより固定することができるため、住宅施工現場における土間形成に関する施工作業を容易かつ迅速に行うことができる。
【００３６】
また、本実施例に係る土間ユニット構造及び土間ユニットの施工方法にあっては、土間ユニット１５のフレーム３７が繊維強化プラスチックにより一体成形により形成されているため、土間ユニット１５を予め工場にて容易かつ迅速に、多量に製造して準備しておくことが可能である。また、フレーム３７が繊維強化プラスチックにより形成されているため、全体として軽量であり、搬送や施工の際の取り扱いも容易に行うことができる。更に、施工されて勝手口の土間として使用された場合には、対衝撃性にも優れることから、長年に亘る使用にも充分に耐えうるものである。
【００３７】
なお、本実施の形態にあっては、上記フレーム３７は繊維強化プラスチックにより形成されている場合を例に説明したが、上記実施の形態には限定されない。
また、本実施の形態にあっては、土間ユニット１５が、布基礎１７と床受け材１６とにより支持されている場合を例に説明したが、上記実施例に限定されず、例えば、布基礎と独立基礎とにより支持されていてもよい。
【００３８】
更に、本実施の形態にあっては、本発明に係る土間ユニット構造及び土間ユニット施工方法を住宅の勝手口に適用した場合を例に説明したが、上記実施の形態には限定されず、住宅の土間であれば適用でき、本発明に係る土間ユニットを用いて住宅の玄関を形成してもよい。
また、土間ユニットの具体的形態に関しては上記実施例には限定されない。
【００３９】
