URETHANE HEAT INSULATION BEARING WALL
To provide a urethane heat insulation bearing wall capable of securing a bearing capacity as a bearing wall while enhancing heat insulation by using hard urethane foam by field spraying as a heat insulating material.SOLUTION: An urethane heat insulation bearing wall 1 comprises: two upper and lower horizontal members 2 and 4; two right and left vertical members 3 and 3; a bearing surface member 6 fixed so as to close an opening on one side of a rectangular frame 5 formed by the horizontal members 2 and 4 and the vertical members 3 and 3; and a urethane heat insulating material 8 which fills a space formed by the frame 5 and the bearing surface member 6 by spraying in the field. The inner peripheral surface of the frame 5 is covered from an edge side on one side to the vicinity of an edge side on the other side with an unbonded material 7 for inhibiting adhesion between the frame 5 and the urethane heat insulating material 8. The urethane heat insulating material 8 is filled so as to fill the space formed by the frame 5 and the bearing surface material 6, and bonded from the vicinity of the edge on the other side not covered with the unbonded material 7 on the inner peripheral surface of the frame 5 to the edge on the other side.SELECTED DRAWING: Figure 2
【課題】現場吹き付けによる硬質ウレタンフォームを断熱材として用いることによって断熱性を高めながら、耐力壁としての耐力性能も確保することができるウレタン断熱耐力壁を提供すること。【解決手段】上下２本の水平材２、４と、左右２本の垂直材３、３と、水平材２、４及び垂直材３、３によって形成される方形の枠５の一方側の開口部を塞ぐように固定される耐力面材６と、枠５及び耐力面材６によって形成される空間に現場吹き付けによって充填されるウレタン断熱材８と、を備え、枠５の内周面は、一方側の縁辺から他方側の縁辺近傍まで、枠５とウレタン断熱材８との接着を阻害するアンボンド材７で被覆され、ウレタン断熱材８は、枠５及び耐力面材６によって形成される空間を満たすように充填されて、枠５の内周面のアンボンド材７で被覆されていない他方側の縁辺近傍から他方側の縁辺までと接着していることを特徴とするウレタン断熱耐力壁１。【選択図】図２
