本発明は、床断熱構造及び断熱材保持金物に関する。   The present invention relates to a floor heat insulating structure and a heat insulating material holding hardware.

左右の大引間に床断熱材が配置されると共に、大引の上に床板が根太レスで設置された床断熱構造は、従来より知られている。   2. Description of the Related Art Conventionally, a floor heat insulating structure in which a floor heat insulating material is disposed between left and right large draws, and a floor board is installed on the large draws without joists.

しかしながら、上記のような根太レスの床断熱構造では、大引が鋼製大引等の金属製大引である場合、大引が熱橋となって、床に求められる断熱性能が確保されないという問題を生じる。   However, in the joist-less floor insulation structure as described above, when the draw is a metal draw, such as a steel draw, the draw becomes a thermal bridge and the insulation performance required for the floor is not secured. Cause problems.

そこで、大引による熱橋を軽減する、ないしは、なくすため、大引と床板との間に大引断熱材を介設することが考えられる。   Therefore, in order to reduce or eliminate the thermal bridge due to the large drawing, it is conceivable to provide a large thermal insulation between the large drawing and the floor board.

しかし、床の施工は、左右の大引間に床断熱材を保持させたのちに、床板を大引の上に設置するという手順で進められるため、大引と床板との間に大引断熱材を介設する場合は、床板を設置する前の段階で、床断熱材を左右の大引間に適正に保持させなければならず、また、大引断熱材も大引の上に適正に保持させなければならず、そのため、上記のような従来の床断熱材保持金物では、大引間の床断熱材を適正に保持することはできても、大引断熱材を適正に保持することはできず、大引断熱材保持用の他の保持金物を用いて大引断熱材の保持を行わなければならなくて、施工に手間を要すると共に、コストも高くつくという問題がある。   However, the floor construction is carried out in the procedure of holding the floor insulation between the left and right large draws and then installing the floorboard on the large draw, so the large draw insulation between the large draw and the floorboard When installing the material, the floor insulation must be properly held between the left and right draws before installing the floorboard, and the draw insulation is also properly placed on the draws. Therefore, in the conventional floor insulation holding hardware as described above, even if the floor insulation between the large draws can be properly retained, the large insulation is properly retained. However, it is necessary to hold the large thermal insulator using other holding hardware for retaining the large thermal insulator, and there is a problem that the construction is troublesome and the cost is high.

本発明は、上記のような問題点に鑑み、左右の金属製大引間に床断熱材を適正に保持することができると共に、大引上に大引断熱材を適正に保持することができ、しかも、それらの保持状態を、手間を要さず、コスト的に有利に形成することができる床断熱構造及び断熱材保持金物を提供することを課題とする。   In view of the above problems, the present invention can properly hold the floor insulation between the left and right metal drawing, and can properly hold the drawing insulation on the drawing. Moreover, it is an object of the present invention to provide a floor heat insulating structure and a heat insulating material holding hardware which can be formed in such a holding state with no cost and advantageous in terms of cost.

上記の課題は、左右の大引間に床断熱材が配置されると共に、前記大引の上に床板が根太レスで設置された床断熱構造において、
