【発明の属する技術分野】
本発明は、天井に横架される天井梁の上面両側に天井パネルを構成する上面板の側縁部分を配置載設してなる天井支持構造に関する。
【０００２】
【従来の技術】
従来から、家屋の小屋裏天井において、図４に示す如く、天井に横架される天井梁６の上面両側に天井パネル７を構成する上面板８の側縁部分を配置載設してなる天井支持構造が知られている。この場合、天井パネル７の本体部分は断熱材料でなり、上面板８は木質合板でなる。又、天井梁６は木質角材でなり、その断面形状は上下に長い長方形状である。
【０００３】
しかしながら、この場合、天井梁６が木質角材でなるため、断熱性を付与されて重量物となる天井パネル７を支持するには強度不足となりがちで、該天井パネル７を確実に支持することができないものであった。又、天井梁６の部位及びその近辺部位には断熱材料が存在せず、同天井梁６の付近には断熱性が付与されない構造となっていて、室内と天井裏との間における断熱性能は十分に保持されないものであった。
【０００４】
又、図５に示す如く、上辺部１、下辺部２、中辺部３でなる断面略エ型の金属製型材４の上辺部１及び下辺部２の外側面に木質材５を固着してなる天井梁６も提案されており、この場合は、天井に横架される同天井梁６の上辺部１上の木質材５の上面両側に、天井パネル７を構成する上面板８の側縁部分を配置載設した天井支持構造となる。ここで、天井パネル７は、内部に断熱材１２が充填された矩形枠材１３の両面側に上面板８及び下面板１４を貼着一体化して形成されている。
【０００５】
この場合、天井パネル７はその内部に断熱材１２が充填されて重量物となるものの、断面略エ型の金属製型材４を主体とする強固な天井梁２の間に同天井パネル７は確実に支持される。しかし、上記の場合と同様に、天井梁６の付近には断熱性が付与されない構造となるため、室内と天井裏との間における断熱性能は十分に保持されないものであった。
【０００６】
特に、この場合は、天井梁６の主体が金属製型材４でなるため、該金属製型材４の上辺部１の上下間では熱が伝わり易くなっており、該上辺部１の下面に結露を発生し易いものであった。更には、金属製型材４全体を熱が伝わって、該金属製型材４の中辺部３や下辺部２の表面、或いは、室内側表面にまで結露が発生してしまうこともあった。
【０００７】
【発明が解決しようとする課題】
本発明は、上記従来の技術における問題を悉く解決するために発明されたもので、その課題は、室内と天井裏との間における断熱性能が確保されて、結露の発生も防止される天井支持構造を提供することである。
【０００８】
【課題を解決するための手段】

【０００９】
したがって、この場合、天井梁の主体が断面略エ型の金属製型材でなり、該天井梁は強固なものとなるため、重量物となる天井パネルであってもこれを確実に支持することができる。又、前記断面略エ型の金属製型材の上辺部及び下辺部の外側面に木質材を固着して天井梁が形成されるため、該天井梁上に小屋束を立設固定したり同天井梁下に室内側表面天井材を取着固定したりする固定作業を、前記上下の木質材を使用して容易且つ確実に行なうことができる。
【００１０】
しかも、天井に横架される前記天井梁の上辺部上の木質材の上面両側に、天井パネルを構成する上面板の側縁部分が配置載設され、該両側の上面板の側縁部分上には断熱部材が載置されるため、該断熱部材によって同天井梁の付近に断熱性を付与した構造となり、室内と天井裏との間における断熱性能は十分に確保される。又、それ故に、天井梁の主体が熱伝達し易い金属製型材でなっていても、同天井梁の周辺における結露の発生は防止される。
【００１１】
更には、前記天井パネルを構成する上面板の側縁部分が相互の側縁端間に間隙をあけて配置載設されるため、該間隙をガイドラインとして防露対策の必要な所定位置に断熱部材を容易に載置することができる。又、その際、上面板の側縁端間の間隙に断熱部材の下面に突設した凸起が係合されるため、同断熱部材は位置決めされてずれ動かないよう確実に載置固定される。
【００１２】
本発明の請求項２記載の天井支持構造は、上記請求項１記載の天井支持構造において、内部に断熱材が充填された矩形枠材の両面側に上面板及び下面板を貼着一体化して天井パネルを形成し、天井梁の両側に配置される同天井パネルの矩形枠材上までを覆い得る巾寸法の帯板状に断熱部材を形成したことを特徴とシテイル。
【００１３】
したがって、この場合は特に、内部に断熱材が充填された矩形枠材の両面側に上面板及び下面板を貼着一体化して天井パネルは形成されており、天井梁の付近以外の同天井パネルの部位において十分な断熱性能が得られる。しかも、天井梁の両側に配置される天井パネルの矩形枠材上までを覆い得る巾寸法の帯板状に断熱部材が形成されるため、該帯板状の断熱部材と同天井パネルの断熱材とで天井平面はその全体が連続的に覆われて断熱され、断熱性能はより向上される。
【００１４】
本発明の請求項３記載の天井支持構造は、上記請求項２記載の天井支持構造において、帯板状の長手方向に沿ったリブ状の凸起を断熱部材の下面に一体形成したことを特徴としている。
【００１５】
したがって、この場合は特に、断熱部材の下面に形成される凸起が帯板状の長手方向に沿ったリブ状となるため、該凸起は長手方向全長にわたって天井パネル間の上記間隙に係合し、同断熱部材がより容易、確実に載置固定される。又、リブ状で長手方向の凸起は帯板状の断熱部材の下面に、発泡樹脂成形等によって簡単に一体形成される。

又、断熱部材１０はポリウレタンやポリ塩化ビニル等の合成樹脂の発泡体等でなり、その下面のリブ状の凸起１１と一体に注型成形や押出成形によって形成されたものである。断熱部材１０は帯板状で、その巾寸法Ｌが天井梁６の両側に配置される天井パネル７の矩形枠材１３上間にわたるよう設定されている。凸起１１は前記上面板８間の間隙９に略合致する形状寸法に形成されており、該間隙９に嵌め込むようにして係合される。
【００２１】
したがって、該実施形態の天井支持構造においては、天井梁６の主体が断面略エ型の金属製型材４でなり、該天井梁６は強固なものとなるため、断熱性能が付与されて重量物となる天井パネル７であってもこれを確実に支持することができる。又、前記断面略エ型の金属製型材４の上辺部１及び下辺部２の外側面に木質材５を固着して天井梁６が形成されるため、該天井梁６上に小屋束を立設固定したり同天井梁６下に室内側表面天井材を取着固定したりする固定作業を、前記上下の木質材５を使用して容易且つ確実に行なうことができる。
【００２２】
しかも、天井に横架される前記天井梁６の上辺部１上の木質材５の上面両側には、天井パネル７を構成する上面板８の側縁部分が配置載設され、該両側の上面板８の側縁部分上には断熱部材１０が載置されるため、該断熱部材１０によって同天井梁６の付近に断熱性を付与した構造となり、室内と天井裏との間における断熱性能は十分に確保される。又、それ故に、天井梁６の主体が熱伝達し易い金属製型材４でなっていても、同天井梁６の周辺における結露の発生は防止される。
【００２３】
更に、前記天井パネル７を構成する上面板８の側縁部分は相互の側縁端間に間隙９をあけて配置載設されるため、スリット状の同間隙９をガイドラインとして防露対策の必要な所定位置に断熱部材１０を容易に載置することができる。又、その際、上面板８の側縁端間の間隙９に断熱部材１０の下面に突設した凸起１１が嵌め込むようにして係合されるため、同断熱部材１０は位置決めされてずれ動かないよう確実に載置固定される。この場合、小屋裏における設置であり、釘やネジ等による固定は不要で、前記凸起１１の係合だけでも十分な固定強度が得られる。
【００２４】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ceiling support structure in which side edge portions of an upper surface plate constituting a ceiling panel are arranged and mounted on both sides of an upper surface of a ceiling beam suspended on a ceiling.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, a ceiling formed by arranging side edges of an upper surface plate 8 constituting a ceiling panel 7 on both sides of an upper surface of a ceiling beam 6 laid on the ceiling in a roof behind a house. Support structures are known. In this case, the main body of the ceiling panel 7 is made of a heat insulating material, and the top plate 8 is made of wood plywood. The ceiling beam 6 is made of wooden timber, and its cross-sectional shape is a vertically long rectangular shape.
[0003]
However, in this case, since the ceiling beam 6 is made of a wooden timber, the strength tends to be insufficient for supporting the ceiling panel 7 which is provided with heat insulation and is heavy, so that the ceiling panel 7 cannot be reliably supported. It was impossible. In addition, there is no heat insulating material in the portion of the ceiling beam 6 and the vicinity thereof, and there is a structure in which heat insulation is not provided in the vicinity of the ceiling beam 6, and the heat insulating performance between the room and the ceiling is low. It was not sufficiently retained.
[0004]
Also, as shown in FIG. 5, the wooden material 5 is fixed to the outer surface of the upper side 1 and the lower side 2 of the metal mold 4 having a substantially D-shaped cross section including the upper side 1, the lower side 2, and the middle side 3. In this case, on both sides of the upper surface of the wooden material 5 on the upper side 1 of the ceiling beam 6 laid on the ceiling, side edges of the upper surface plate 8 constituting the ceiling panel 7 are proposed. A ceiling support structure with the parts arranged and mounted. Here, the ceiling panel 7 is formed by sticking and integrating an upper surface plate 8 and a lower surface plate 14 on both sides of a rectangular frame member 13 in which a heat insulating material 12 is filled.

In this case, the ceiling panel 7 is filled with the heat insulating material 12 and becomes heavy, but the ceiling panel 7 is securely provided between the strong ceiling beams 2 mainly composed of the metal mold member 4 having a substantially D-shaped cross section. Supported by However, as in the case described above, a structure in which heat insulation is not provided in the vicinity of the ceiling beam 6 does not sufficiently maintain the heat insulation performance between the room and the inside of the ceiling.
[0006]
In particular, in this case, since the main body of the ceiling beam 6 is made of the metal mold 4, heat is easily transmitted between the upper and lower sides of the upper side 1 of the metal mold 4, and condensation is formed on the lower surface of the upper side 1. It was easy to occur. Further, heat is transmitted through the entire metal mold member 4, and dew may be formed on the surface of the middle side portion 3 or the lower side portion 2 of the metal mold member 4 or even on the indoor side surface.
[0007]

In addition, since a wooden beam is fixed to the outer surface of the upper side and the lower side of the metal mold having a substantially D-shaped cross section to form a ceiling beam, a shed bundle is erected and fixed on the ceiling beam. The fixing work of attaching and fixing the indoor-side surface ceiling material under the beams can be easily and reliably performed using the above-mentioned upper and lower wooden materials.
[0010]
In addition, on both sides of the upper surface of the wooden material on the upper side of the ceiling beam laid on the ceiling, side edges of the upper panel constituting the ceiling panel are arranged and mounted, and on both sides of the upper panel on the both sides. Since a heat insulating member is placed on the ceiling, the heat insulating member has a structure in which heat insulating properties are provided in the vicinity of the ceiling beam, so that the heat insulating performance between the room and the space above the ceiling is sufficiently ensured. Therefore, even if the main body of the ceiling beam is made of a metal mold material that easily conducts heat, the occurrence of dew condensation around the ceiling beam is prevented.

A ceiling panel is formed, and the heat insulating member is formed in a strip shape having a width dimension capable of covering up to a rectangular frame material of the ceiling panel arranged on both sides of the ceiling beam.
[0013]
Therefore, in this case, especially, the ceiling panel is formed by adhering and integrating the upper surface plate and the lower surface plate on both sides of the rectangular frame material filled with the heat insulating material therein, and the ceiling panel other than the vicinity of the ceiling beam. Sufficient heat insulating performance can be obtained at the part. Moreover, since the heat insulating member is formed in a strip shape having a width dimension capable of covering up to the rectangular frame material of the ceiling panel disposed on both sides of the ceiling beam, the heat insulating member of the strip panel and the heat insulating material of the ceiling panel are formed. As a result, the entire ceiling plane is continuously covered and insulated, and the heat insulation performance is further improved.
[0014]
A ceiling support structure according to a third aspect of the present invention is the ceiling support structure according to the second aspect, wherein a rib-like protrusion along the longitudinal direction of the strip is integrally formed on the lower surface of the heat insulating member. And
[0015]
Therefore, in this case, particularly, the protrusion formed on the lower surface of the heat insulating member becomes a rib shape along the longitudinal direction of the band plate, and the protrusion engages with the gap between the ceiling panels over the entire length in the longitudinal direction. Then, the heat insulating member is more easily and reliably mounted and fixed. Further, the rib-shaped projections in the longitudinal direction are easily formed integrally with the lower surface of the strip-shaped heat insulating member by foaming resin molding or the like.
