Description

【０００１】
【発明の属する技術分野】
本発明は、住宅等の建物のベランダ、バルコニー及び室内床に用いられる、波板と下板とを有するデッキ床であって、雨樋等の横架部材を載せる溝が設けられ、床材と支持部材を兼用した溝付デッキ床に関するものである。
【０００２】
【従来の技術】
特開平１１−２００５４４には、床板の平坦下面に金属製波板が重ねられ、床板が金属製波板の山部に接合されて、床板と金属製波板とを一体化した構造とすることにより剛性の高いものとし、部材の軽量化も実現した床パネルが示されている。
【０００３】
【発明が解決しようとする課題】
しかし、この床パネルをベランダやバルコニーのデッキ床として用いる場合、雨樋部を他の部分より低くする必要がある。デッキ床の上部に嵩上げ用の部材を取付けることで溝部を形成することが考えられるが、施工に手間がかかる。しかも、デッキ高さが制限されると、十分な剛性を確保できず、それより衝撃音や振動が下階に伝わり易くなり、居住性に悪影響を与えることになる。他の方法として、上記デッキ床の上部の一部を切欠くことで溝部を形成することも考えられるが、デッキ床に自重、載荷荷重がかかると、切欠き部に曲げ作用により圧縮が働き、溝部において局部座屈を生じることとなる。すると、溝部における波板は全く荷重に抵抗できず、下板のみで抵抗することとなる。
【０００４】
本発明は、前記課題に鑑みなされたものであり、全体の厚さが薄く、十分な剛性・強度・遮音性を有し、施工性が良い、床材と支持部材を兼用した溝付デッキ床及びその製造方法を提供することを目的とする。
【０００５】
【課題を解決するための手段】
前記課題を解決するための本発明の請求項１に記載の溝付デッキ床は、山部と谷部とを連続させた波形に形成された金属製の波板と、この板の谷部に接合された金属製の下板とを備えるデッキ床であって、前記波板の山部に対して、前記山部を横断する方向に列設された凹部を設けることにより、溝を形成し、この凹部の周囲に補強部を設けたことを特徴とするものである。
溝付デッキ床の製作及び施工が、少ない工程で可能となり低コストで提供でき、比較的薄い部材となることにより、他の室内床との高さ調整が容易となる。また、凹部の周囲を補強するため、溝部の曲げ剛性が上昇し、衝撃音等の遮音性に優れた床構造となる。
【０００６】
請求項２に記載の溝付デッキ床は、前記凹部は、前記山部の切欠きにより形成され、前記補強部は、前記凹部の周りの斜面に長手方向に延在する凸又は凹の突起により形成されていることを特徴とする請求項１記載の溝付デッキ床である。溝部の波板表面に突起を設けることにより、溝部の波板の曲げ剛性を上昇させる。すると、溝部においても波板断面が曲げモーメントに対して抵抗し、高い剛性及び強度を保つことが可能となる。また、追加工により、切欠き部を渡す台形状に加工した板を接合しても良い。
【０００７】
請求項３に記載の溝付デッキ床は、前記凹部は、前記山部の切欠きにより形成され、前記補強部は、前記切欠きの下方に向かう折り返しにより形成されていることを特徴とする請求項１記載の溝付デッキ床である。
切欠き部の波板に折り返しを設けることにより、切欠き端部の剛性を上昇させることができるので、溝部においても、波板断面が曲げモーメントに対して抵抗し、高い剛性及び強度を保つことが可能となる。更に、波板表面に突起を設けることで、より高い剛性及び強度を確保することができる。
【０００８】
請求項４に記載の溝付デッキ床は、前記凹部は、前記山部の押し潰しにより形成され、前記補強部は、山部の両側の斜面が押し潰された連続部分により形成されていることを特徴とする請求項１記載の溝付デッキ床である。
山部において、押し潰しによる凹部であり、部材が連続していることにより、溝部での座屈は生じない。更に、波板表面に突起を設けることで、より高い剛性及び強度を確保することができる。
【０００９】
請求項５に記載の溝付デッキ床は、前記山部に床板を設置したことを特徴とする請求項１から請求項４のいずれかに記載の溝付デッキ床である。
溝付デッキ床の上下板と波板に金属製板を用いれば、剛性、強度の高いデッキ床となる。また、上板に関しては木製板やパーティクルボードを使用することで、合理的なデッキ床とすることができる。
【００１０】
請求項６に記載の溝付デッキ床は、前記凹部に樋状の横架材を設置したことを特徴とする請求項１から請求項５のいずれかに記載の溝付デッキ床である。
ベランダやバルコニーのデッキ床として、雨樋部を簡易に構成することができる。また、基準高さに対し、一部分の高さを低くするデッキ床であるので、室内のフリーアクセス床としての適用も可能である。
【００１１】
請求項７に記載の溝付デッキ床の製造方法は、ロール形成により山部と谷部とを連続させた波形に形成された金属製の波板と、この波板の谷部に接合された金属製の下板とを備え、前記波板の山部を横断する方向に列設された凹部からなる溝を形成した溝付デッキ床の製造方法であって、ロール成形前の薄板の山部に相当する部分に列状に並んだ切欠き加工を施し、前記山部及び谷部を形成するロール成形時に、前記切欠きにより形成された凹部の周囲の斜面に長手方向に伸びる凸又は凹の突起をロール成形により形成してから、前記下板を接合することを特徴とするものである。
金属製板の切欠き加工を施し、ロール成形を行ない波板とした後、波板の谷部に下板を接合するのみで、溝付デッキ床の製造ができるため、少ない工程数でのデッキ床の製造及び施工が可能となり、大幅に低コストでデッキ床を提供できる。
【００１２】
請求項８に記載の溝付デッキ床の製造方法は、ロール成形により山部と谷部とを連続させた波形に形成された金属製の波板と、この波板の谷部に接合された金属製の下板とを備え、前記波板の山部を横断する方向に列設された凹部からなる溝を形成した溝付デッキ床の製造方法であって、ロール成形前の薄板の山部に相当する部分に列状に並んだ切欠き加工又はスリット加工を施し、前記山部及び谷部を形成するロール成形後に、前記切欠き又はスリットの部分に押し込み加工を施して前記凹部の形成と同時に折り返し又は押し潰しによる補強部を形成し、前記下板を接合することを特徴とするものである。
金属製板の切欠き又はスリット加工を施し、ロール成形を行ない波板とした後、切欠き又はスリット加工部分を押し込み、波板の谷部に下板を接合するのみで、溝付デッキ床の製造ができるため、少ない工程数でのデッキ床の製造及び施工が可能となり、大幅に低コストでデッキ床を提供できる。
【００１３】
【発明の実施の形態】
以下、図面を参照しつつ本発明の実施の形態例を説明する。図１から図３において、本発明の第１実施形態を説明する。
【００１４】
図１は本発明を適用した場合の第１実施形態の斜視図を示すもので、デッキ床１は、波板２、下板３、床板４からなる。波板２は、鋼製の折板によるもので、山部２a及び谷部２bがR状、斜面部２cが平板状をなした波形に形成されたものである。第１実施形態においては、斜面部２cには補強部としての突起７が設けられている。波板２の山部２aには、山部２aを横断する方向に波板凹部５が列設されている。３は金属製の下板であり、波板２の両端の谷部２bに沿う方向で、下板３から直角上方に、波板２の山部２cと同じ高さで立上部３aが設けられている。立上部３aには、波板凹部５の列設方向に、下板凹部６が設けられている。デッキ床１は、波板２が谷部２bで下板３と、波板２が山部２aで床板４と接合されており、床板４は下板３の両端の立上部３a端部でも接合されている。波板２と下板３の接合及び波板２と床板４の接合、及び床板４と下板３の接合には、リベットやスポット溶接、接着剤、ネジ、釘等を用いることができる。列設された波板凹部５及び下板凹部６の底部の高さを揃えると、樋等の横架材を載せることができる溝Aとすることができる。この時、波板凹部５と下板凹部６の高さを調節することにより、溝Aに傾斜を付けることもできる。また、デッキ床１をバルコニーやベランダ等に用いる場合、雨樋用としての溝Aの位置は端部に設けるが、その場合、自重や載荷荷重により生じる曲げモーメントが小さくてすむ。また、溝Aの部分には、雨樋等の横架部材を載せるため、床板４が接合されていない。
【００１５】
図２に、第１実施形態の、デッキ床１の溝形成部における波板２と下板３の断面図を示す。波板２の斜面部２cに突起７が設けられている。この突起７は波板２の斜面部２cに凹凸に形成され、波板２の長手方向全長に延在している。溝形成部における波板２の斜面部２cには、デッキ床１の曲げ作用により圧縮力が働き、局部座屈が生じてしまう。そこで、波板２の斜面部２cに突起７を設けて波板２の曲げ剛性を向上させ、局部座屈を防止する。突起７は、波板凹部５に近い位置に設ける程、本数が多い程有効になる。また、圧縮力は波板方向に働くので、突起は波形に平行である方が有効に作用する。なお、突起７の形状は、半円状等種々のものでよく、波板の長手方向に千鳥状に不連続に配設される物であってもよい。又、突起７は、波板２の斜面部２cにおいて、波板凹部５の周りにのみ設けられるものであっても良い。
【００１６】
図３に、第１実施形態における波板２のロール成形前の平板２’の展開図を示す。図３において、点線は、ロール成形後の波板２の山部２aを、1点鎖線はロール成形後の波板２の谷部２bを、点線と1点鎖線の間はロール成形後の波板２の斜面部２cを示す。平板２’には、点線を中心に、概六角形の切欠き部８が作成されている。ロール形成後、切欠き部８は波板凹部５となり、応力集中が発生するため、切欠き線の交点にR部を設けたり、切欠き線のうち山部２aと交叉する部分をやや斜めにすると良い。切欠き部８の間隔は、ロール成形後の波板２の山部２aから隣接する山部２aまでの、突起７も含む延べ長さから、ロール加工による伸びを差し引いた距離である。第１実施形態における波板２の製造方法として、まず平板２’にパンチ等で切欠き部８を作成する。そして、ロール成形により平板２’に山部２a、谷部２bを成形し、それと同時に平板２’の斜面部２cに突起７をロール成形する。例えば、ロールの表面に凹凸を設けることにより、波板２の山部２a及び谷部２bの形成と同時に突起７を形成することができる。
【００１７】
次に、図４から図６において、本発明の第２実施形態を説明する。
【００１８】
図４は本発明をデッキ床に適用した場合の第２実施形態の、デッキ床１の溝形成部における波板２と下板３の断面図を示す。波板凹部５に、補強部としての折り返し部９が設けられている。折り返し長さは長い方が良いが、曲げ加工時に両側の折り返し部が干渉しない長さとし、切欠く三角形の底辺の半分よりやや短いと、加工が容易である。折り返しの角度は９０度程度に設定するのが良い。この波板凹部５と下板凹部６の列設により、溝Aが形成される。
【００１９】
図５に、第２実施形態における波板２のロール成形前の平板２’の展開図を示す。平板２’において、点線は、ロール成形後の波板２の山部２aを、1点鎖線はロール成形後の波板２の谷部２bを、点線と1点鎖線の間はロール成形後の波板２の斜面部２cを示す。平板２’には、点線を中心に、概I字形の切欠き部８が作成されている。ロール形成後、切欠き部８は波板凹部５となり、応力集中が発生するため、切欠き線の交点にR部を設けたり、切欠き線のうち山部２aと交叉する部分をやや斜めにすると良い。切欠き部８の間隔は、ロール成形後の波板２の山部２aから隣接する山部２aまでの延べ長さから、ロール加工による伸びを差し引いた距離である。第２実施形態における波板２の製造方法として、平板２’にパンチ等で切欠き部８を作成する。そして、ロール成形により平板２’に山部２a、谷部２bを成形する。その後、図６に示す治具配置断面図により、折り返し部９を成形する。図６における治具配置は、波板台１１aと、押え具１１bとからなる。波板台１１aは、波板２の山形の一つと概同形の断面をしており、波板２の山部２aに相当する部分が、折り返し部９の形状に合わせた凹部となっている。波板２を、波板台１１a上に置き、押え具１１bで押え、押し込み具１１cで下方に押し込むことで、折り返し部９を形成する。
【００２０】
次に、図７から図９において、本発明の第３実施形態を説明する。
【００２１】
図７は本発明をデッキ床に適用した場合の第３実施形態の、デッキ床１の溝形成部における波板２と下板３の断面図を示す。波板凹部５に、補強部としての押し潰し部１０が設けられている。この場合、波板２の山部２aにおいて、部材が連続しているので、この部分での座屈は生じない。この波板凹部５と下板凹部６の列設により、溝Aが形成される。
【００２２】
図８に、第３実施形態における波板２のロール成形前の平板２’の展開図を示す。波板２において、点線は、ロール成形後の波板２の山部２aを、1点鎖線はロール成形後の波板２の谷部２bを、点線と1点鎖線の間はロール成形後の波板２の斜面部２cを示す。平板２’には、点線を中心に、スリットを２本加工する。ロール形成後、切欠き部８は波板凹部５となり、応力集中が発生するため、切欠き線の交点にR部を設けたり、切欠き線のうち山部２aと交叉する部分をやや斜めにすると良い。切欠き部８の間隔は、ロール成形後の波板２の山部２aから隣接する山部２aまでの延べ長さから、ロール加工による伸びを差し引いた距離である。第３実施形態における波板２の製造方法として、平板２’にパンチ等で切欠き部８を作成する。そして、ロール成形により波板２に山部２a、谷部２bを成形する。その後、図９に示す治具配置により、押し潰し部１０を成形する。図９における治具配置は、波板台１１aと、押え具１１bとからなる。波板台１１aは、波板２の山形の一つと概同形の断面をしており、波板２の山部２aに相当する部分が、押し潰し部１０の形状に合わせた凹部となっている。波板２を、波板台１１a上に置き、押え具１１bで押え、押し込み具１１cで下方に押し込むことで、押し潰し部１０を形成する。
【００２３】
次に、図１０において、本発明の第４実施形態を説明する。
【００２４】
図１０は本発明をデッキ床に適用した場合の第４実施形態の、デッキ床１の溝形成部における波板２と下板３の断面図を示す。波板凹部５に、補強部としての台形状板１２が渡され接合されている。台形状板１２は、波板凹部５を塞ぐ平坦部と、斜面部２cに途中まで沿わせた形状の斜面部を有する台形の連続により形成されている。波板２の斜面部２cと、台形状板１２の斜面部を接合し固定することで、波板凹部５を補強している。この波板凹部５と下板凹部６の列設により、溝Aが形成される。
【００２５】
以上に、本発明の実施形態を示したが、波板２の山部２a及び谷部２bを平坦部とした台形状とすることもでき、波板２の山部２a及び谷部２bにおける平坦部を大きくし、斜面部２cを下板３から垂直にすることで、波板２の断面形状を四角形等の矩形の繰り返しとすることもできる。
【００２６】
また、床板４に金属製板を用いれば、剛性、強度の高い床材となるが、デッキ床１の強度には、溝部Aの強度が大きく影響するので、床板４に関しては、合板やパーティクルボード等の方形板の下地材を用いることで、合理的なデッキ床とすることができる。また、床板４の施工については、波板２及び下板３による溝付デッキ床に現場で床板４を取付けても、波板２及び下板３による溝付デッキ床に工場で予め床板４を接合してから現場に運んできても良い。
【００２７】
第１実施形態から第４実施形態において、下板３及び下板立上部３aに、波板２の両端の谷部２bに沿う方向に突起７を設けることで、より座屈に対して強くなる。また、第２実施形態から第４実施形態において、更に波板２の斜面部２cに突起７を設けることで、よりデッキ床の剛性を高めることができる。
【００２８】
下板３については、波板２の山谷の長手方向に分割されていても良い。また、波板２の断面において、山谷の長手方向の両端が谷部２bとなっているが、波板２を上下逆にした形とし、山谷の長手方向の両端を山部２aとすると、山谷の長手方向の両端に最も近い位置の谷部２bまでのみ下板３を接合し、下板３の立上部３aを無くすこともできる。
【００２９】
【発明の効果】
請求項１から請求項６の溝付デッキ床によると、比較的薄い部材となることにより、他の室内床との高さ調整が容易となる。また、波板表面に突起を設けたり、凹部に折り返しを設けたり、波板の山部の押し潰しにより凹部を設けることにより、溝部の補強を行うことで、波板断面が曲げモーメントに対して抵抗し、高い剛性及び強度を保つことが可能となり、衝撃音等の遮音性にも優れた床構造となる。

This shows a floor panel that has higher rigidity and realizes weight reduction of members.
[0003]
[Problems to be solved by the invention]
However, when this floor panel is used as a deck floor of a veranda or a balcony, it is necessary to make the rain gutter part lower than other parts. Although it is possible to form a groove part by attaching the member for raising to the upper part of a deck floor, construction takes time. Moreover, if the deck height is limited, sufficient rigidity cannot be secured, and impact noise and vibration are more easily transmitted to the lower floor, which adversely affects the comfortability. As another method, it is conceivable to form a groove part by notching a part of the upper part of the deck floor, but when the deck floor is subjected to its own weight and load, compression works by bending action on the notch part, Local buckling will occur in the groove. Then, the corrugated plate in the groove cannot resist the load at all, and only the lower plate resists.

The grooved deck floor according to claim 5 is the grooved deck floor according to any one of claims 1 to 4, wherein a floor board is installed in the mountain portion.
If metal plates are used for the upper and lower plates and corrugated plates of the grooved deck floor, the deck floor has high rigidity and strength. As for the upper board, a reasonable deck floor can be obtained by using a wooden board or a particle board.
[0010]
The grooved deck floor according to claim 6 is the grooved deck floor according to any one of claims 1 to 5, wherein a saddle-like horizontal member is installed in the recess.
The rain gutter can be easily constructed as a deck floor for a veranda or balcony. Moreover, since it is a deck floor in which a part of the height is lowered with respect to the reference height, it can be applied as an indoor free access floor.

Therefore, the projection 7 is provided on the slope portion 2c of the corrugated plate 2 to improve the bending rigidity of the corrugated plate 2 and prevent local buckling. The protrusions 7 are more effective as the number of the protrusions 7 is increased as the protrusions 7 are provided closer to the corrugated recess 5. Further, since the compressive force acts in the direction of the corrugated plate, it is more effective that the protrusion is parallel to the corrugation. The protrusions 7 may have various shapes such as a semicircular shape, and may be discontinuously arranged in a staggered manner in the longitudinal direction of the corrugated sheet. Further, the protrusion 7 may be provided only around the corrugated concave portion 5 on the slope portion 2 c of the corrugated plate 2.
