Description

本発明は、建物ユニット、及びユニット式建物に関する。   The present invention relates to a building unit and a unit type building.

鋼製部材を用いた建物では、冬期、鋼製部材特有の熱橋による影響を受ける。熱橋とは構造体における極端に熱伝導率の大きな部分をいい、この部分は他の部分よりも熱を伝えやすい熱的短絡部となる。
従来、この熱橋対策として、床下地パネルを金属製大引きで支持し、床下地パネルの下側であって大引きを挟んで両側に配置された床断熱材を断熱材支持具で支持し、この断熱材支持具を、大引きと床下地パネルとの間に配置される上面部と、この上面部の両側に設けられ、下端部で断熱材を支持する側面部とを有するコ字型に形成したものがある(例えば、特許文献1参照)。
また、床材が支持される鋼製大引きを断熱材で覆うものがある(例えば、特許文献2参照)。また、床の断熱対策として、スチールハウスの鋼製根太の周囲を断熱材で覆うものがある(例えば、特許文献3参照)。さらに、ユニット式建物では、基礎を断熱基礎とし、この基礎の中を暖めるものがある。
Buildings using steel members are affected by thermal bridges that are unique to steel members in winter. The thermal bridge means a part having extremely large thermal conductivity in the structure, and this part becomes a thermal short-circuit part that can conduct heat more easily than other parts.
Conventionally, as a countermeasure against this thermal bridge, the floor base panel is supported by metal pulls, and the floor insulation located on both sides of the large pull under the floor base panel is supported by a heat insulator support. The U-shaped member having an upper surface portion disposed between the large pull and the floor base panel and a side surface portion provided on both sides of the upper surface portion and supporting the heat insulating material at the lower end portion. (For example, refer to Patent Document 1).
In addition, there is one that covers a steel pulling on which a floor material is supported with a heat insulating material (see, for example, Patent Document 2). Further, as a measure for heat insulation of the floor, there is one that covers the periphery of the steel joists of the steel house with a heat insulating material (for example, see Patent Document 3). Furthermore, some unit type buildings have a foundation as an insulating foundation and warm the foundation.

しかしながら、引用文献1〜3に記載の熱橋対策では、大引きや根太を断熱材等で覆う必要があるので、現場での施工が煩雑となるという問題がある。また、基礎を断熱基礎とし、この基礎の中を暖める熱橋対策では、構造が大がかりになるので施工コストが高くなり、床下換気がとりにくいという問題がある。   However, in the countermeasures against the thermal bridge described in the cited documents 1 to 3, since it is necessary to cover the overdraw and joists with a heat insulating material or the like, there is a problem that the construction at the site becomes complicated. In addition, the thermal bridge measures that use the foundation as the heat insulation foundation and heat the foundation have a problem that the construction becomes large and the construction cost becomes high, and it is difficult to take under-floor ventilation.

In this embodiment as well, the same operations and effects as in the first embodiment can be achieved.

〔実施形態の変形〕
なお、本発明は、前記各実施形態に限定されるものではない。
例えば、前記各実施形態では、易熱伝達梁は下階建物ユニット3の基礎2側に下面を有する長辺床梁12Aとされ、梁用断熱部材8は長辺床梁12Aの下面に取り付けられていた。これに対して、例えば、易熱伝達梁を建物ユニットの屋根部側に上面を有する上梁とし、断熱部材を上梁の上面に取り付けてもよい。要するに、易熱伝達梁は、上下の梁の少なくともいずれか一方とされ、断熱部材は、易熱伝達梁の外部に露出する部分に梁長手方向に沿って取り付けられていればよい。
[Modification of Embodiment]
The present invention is not limited to the above embodiments.
For example, in each of the above embodiments, the heat transfer beam is the long side floor beam 12A having a lower surface on the foundation 2 side of the lower floor building unit 3, and the heat insulating member 8 is attached to the lower surface of the long side floor beam 12A. It was. On the other hand, for example, the heat transfer beam may be an upper beam having an upper surface on the roof side of the building unit, and the heat insulating member may be attached to the upper surface of the upper beam. In short, the easy heat transfer beam may be at least one of the upper and lower beams, and the heat insulating member may be attached to a portion exposed to the outside of the easy heat transfer beam along the beam longitudinal direction.

前記各実施形態では、梁用断熱部材8は、板状に形成された合板81、及び梁用板状断熱材82を接着剤等で接合して構成され、合板81は長辺床梁12Aの下面にボルト83にて取り付けられていた。これに対して、例えば、断熱部材は、上下の梁の少なくともいずれか一方に接着剤等で貼り付けられていてもよい。
前記各実施形態では、梁用板状断熱材82には、防蟻剤が含有されていたが、防蟻剤は含有されていなくてもよい。
In each of the above-described embodiments, the beam heat insulating member 8 is configured by joining a plate-like plywood 81 and a beam plate-like heat insulating material 82 with an adhesive or the like, and the plywood 81 is formed of the long side floor beam 12A. It was attached to the lower surface with bolts 83. On the other hand, for example, the heat insulating member may be attached to at least one of the upper and lower beams with an adhesive or the like.
In each said embodiment, although the plate-shaped heat insulating material 82 for beams contained the termite-proof agent, it does not need to contain the termite-proof agent.

前記各実施形態では、梁用断熱部材8は、長辺床梁12Aの幅方向寸法と略同じ幅方向寸法とされていた。これに対して、例えば、断熱部材は、上下の梁の少なくともいずれか一方の幅方向寸法より大きい幅方向寸法とされていてもよく、小さい幅方向寸法とされていてもよい。要するに、断熱部材は、易熱伝達梁の外部に露出する部分に梁長手方向に沿って取り付けられていればよい。   In each said embodiment, the heat insulation member 8 for beams was made into the width direction dimension substantially the same as the width direction dimension of 12 A of long side floor beams. On the other hand, for example, the heat insulating member may have a width direction dimension that is larger than the width direction dimension of at least one of the upper and lower beams, or may have a smaller width direction dimension. In short, the heat insulating member only needs to be attached along the beam longitudinal direction to a portion exposed to the outside of the heat transfer beam.
