Description

【０００１】
【発明の属する技術分野】
この発明は、建物の基礎の防蟻構造及びユニット建物に関する。
【０００２】
【従来の技術】
近年の高気密・高断熱建物においては、その建物の外壁面または内壁面を断熱するだけではなく、その建物の基礎も断熱して、気密性・断熱性を向上させた基礎断熱建物が普及してきている。
【０００３】
このような基礎断熱建物は、建物の外壁面を断熱する外断熱工法による基礎断熱建物を例にとれば、布基礎の屋外側に基礎断熱材を取り付け、この基礎断熱材を被覆材で覆って布基礎の外側を断熱した構造となっている。
【０００４】
この基礎の断熱構造においては、プラスチック発泡体からなる基礎断熱材を保護する被覆材の下端は、土に接した状態になっていて、布基礎に接していないので、基礎断熱材の下方部分は被覆材で覆われずに露出していて地中に接した状態になっている。
【０００５】
このため、地中に接した状態になっている基礎断熱材のプラスチック発泡体は、土中や床下の白蟻により食害されることになり、この基礎断熱材が白蟻の侵入経路となっていた。
【０００６】
このような白蟻による食害から建物を守ることができる建物の断熱基礎構造として、建物の布基礎の屋外側に断熱材を介して被覆材を取り付けた建物の断熱基礎構造において、一側縁が前記布基礎に埋設されるとともに、他側縁が基礎断熱材の上端部または基礎断熱材を貫通して中間部を覆って断熱材の屋外表面に配設される白蟻遮蔽板を設け、この白蟻遮蔽板と前記被覆材との間を防蟻テ−プを介在させて密着させることが提案されている（特許文献１参照）。

【発明が解決しようとする課題】
ところで、特許文献１に記載されているような建物の断熱基礎構造では、白蟻遮蔽板は、その一側縁が前記布基礎に埋設されるとともに、他側縁が基礎断熱材の上端部または基礎断熱材を貫通して中間部を覆って断熱材の屋外表面に配設されているので、基礎断熱材の下方部分は依然として被覆材で覆われずに露出していて地中に接した状態になっている。
【０００９】
そのため、白蟻遮蔽板より下方の基礎断熱材部分は白蟻に食害されることになり、布基礎の断熱効果が損なわれてしまうという問題があった。
なお、建物の内壁面を断熱する内断熱工法による場合においても、同様の問題が考えられる。
【００１０】
この発明は、上記の問題点を解消し、建物の外壁面を断熱する外断熱工法による基礎断熱建物や、建物の内壁面を断熱する内断熱工法による基礎断熱建物において、基礎部の断熱効果を損なうことがなく、建物を白蟻による食害から守ることができる建物の断熱基礎構造を提供することを目的とする。

A white ant shield plate 40 is attached to the base of the upright portion 101 on the indoor side, and the basic heat insulating material 20 is attached to the side surface of the upright portion 11 on the indoor side.
As shown in FIG. 1, the white ant shield plate 40 is attached to the base portion on the indoor side of the upright portion 101 by being bonded to the base portion 102 via an ant-proof sealing material (not shown).
[0046]
A heat insulating material holding member 60 is fitted to the upper end of the upright portion 101 of the fabric foundation 10 and the upper end of the basic heat insulating material 20. Reference numeral 601 denotes a substrate portion, 602 denotes a hanging portion, and 603 denotes a draining piece.
[0047]
The basic heat insulating material 20, the white ant shielding plate 40, the heat insulating material holding member 60, and the like are not particularly different from the basic heat insulating material 2, the white ant shielding material plate 4, the heat insulating material holding material 6 and the like shown in FIG.
[0048]
The building is built on this heat insulation foundation, but the building to be built is different because it is a building by the internal heat insulation method, but the others are not particularly different from those shown in FIG. Is omitted.
