Description

本発明は、パネルユニットに関する。 The present invention relates to a panel unit.

特許文献１には、２枚の金属外皮の間に芯材が充填された断熱パネルを、縦横に複数枚並べて、１つの壁を形成することが記載されている。 Patent Document 1 describes that a plurality of heat insulating panels in which a core material is filled between two metal outer skins are arranged vertically and horizontally to form one wall.

２枚の金属外皮は、断熱パネルの両側端部に設けられた複数の連結部材のそれぞれに対してビス等で結合されることによって、連結されている。 The two metal outer skins are connected to each of a plurality of connecting members provided at both side ends of the heat insulating panel by being bonded with screws or the like.

各断熱パネルは、上下左右の端面のそれぞれに突条部を有している。縦横に並ぶ断熱パネルは、対向する突条部間にパッキンが充填された状態で接続される。 Each heat insulating panel has ridges on each of the top, bottom, left, and right end faces. The heat insulating panels arranged vertically and horizontally are connected with packing filled between the opposing ridges.

ところで、複数枚のパネルを並べて１つの壁を形成するにあたって、隣接するパネル間に形成される目地の目地幅を極力小さくしたいといった要望がある。 By the way, when forming one wall by arranging a plurality of panels, there is a demand that the joint width of the joint formed between adjacent panels should be as small as possible.

しかし、特許文献１に記載の断熱パネルでは、端面に突条部を有するため、目地幅を小さくすることができず、また、仮に突条部を省略したとしても、連結部材を固定するビスの頭部が邪魔になって、目地幅を小さくすることができない。また、特許文献１に記載の断熱パネルでは、連結部材及びビスを省略した場合には、２枚の金属外皮を連結することができなくて、耐火性が低下するといった問題が生じる。 However, since the heat insulating panel described in Patent Document 1 has a ridge portion on the end face, the joint width cannot be reduced, and even if the ridge portion is omitted, the screw for fixing the connecting member The head gets in the way and the joint width cannot be reduced. Further, in the heat insulating panel described in Patent Document 1, if the connecting member and the screw are omitted, the two metal outer skins cannot be connected, which causes a problem that the fire resistance is lowered.

上記事情に鑑みて、本発明は、耐火性の向上を図ったうえで、隣接するパネル間に形成される目地の目地幅を小さくすることができるパネルユニットを提案することを、目的とする。 In view of the above circumstances, it is an object of the present invention to propose a panel unit capable of reducing the joint width of joints formed between adjacent panels while improving fire resistance.
