UNDERFLOOR HEAT INSULATION STRUCTURE
PROBLEM TO BE SOLVED: To provide an underfloor heat insulation structure capable of improving heat insulation performance under a building floor by a few cost increase.SOLUTION: In an underfloor heat insulation structure having a foundation 1 composed of a standing-up part 1A of projecting from the ground and an underground footing part 1B, a level-raising earthen floor part of layering soil on the earthen floor ground enclosed by the foundation 1, an earthen floor concrete layer 3 and a foundation heat insulation material 2, a groove 3a of the same height in the vertical direction as the ground of the standing-up part outside in its bottom part or a second heat insulation material 4 composed of a material lower in heat conductivity than the soil of concrete and the earthen floor part, is arranged in an edge part for contacting with the heat insulation material 2 in the earthen floor concrete layer 3 by removing partial soil of the level-raising earthen floor part for contacting with the heat insulation material 2.SELECTED DRAWING: Figure 1
【課題】少ないコストアップで、建物床下の断熱性を向上させることのできる床下断熱構造を提供する。【解決手段】地盤から突出する立上り部１Ａと地中のフーチング部１Ｂからなる基礎１と、基礎１で囲まれた土間地盤の上に土が積層された嵩上げ土間部と、土間コンクリート層３と、基礎断熱材２とを備える床下断熱構造であって、断熱材２に接する嵩上げ土間部の一部の土が除去され、土間コンクリート層３における断熱材２に接する縁部に、その底部が立上り部外側の地盤と鉛直方向において同じ高さの溝３ａ、または、コンクリートおよび土間部の土より熱伝導率の低い材料からなる第２の断熱材４が、配設されている。【選択図】図１
