A heat insulating panel disposed in a space between a structural material and an exterior material side by side in one direction or both directions, and an inner support connected to the structural material and disposed along an inner surface of the heat insulating panel. A plate, an outer support plate arranged along the outer surface of the heat insulation panel, and a fastening mechanism that pierces the heat insulation panel and fastens both support plates together, and supports the heat insulation panel in a state of being sandwiched by both support plates. A panel support mechanism and an exterior material support mechanism that connects an outer support plate of the heat insulation panel support mechanism and an exterior material are provided, and the fastening mechanism includes a member that suppresses heat transfer between both support plates. Insulation structure of the building. 2. The heat insulating structure for a building according to claim 1, wherein the fastening mechanism is a rod-shaped heat insulating resin member having screw holes formed on both end surfaces thereof.
The invention is characterized by including a female screw member formed of a metal reinforcing sleeve fitted to the outer peripheral surface of the resin member, and a connecting bolt penetrating each support plate and screwed into a screw hole of the resin member. Thermal insulation structure of the building. 3. The heat insulating structure for a building according to claim 2, wherein the reinforcing sleeve has annular flange portions that respectively cover outer edge portions of both end surfaces of the resin member, and the fastening mechanism includes the reinforcing sleeve. A heat insulating structure for a building, further comprising a heat insulating member interposed between at least one annular flange portion and a support plate facing the annular flange portion. 4. The heat insulating structure for a building according to claim 2 or 3, wherein the female screw member is composed of a plurality of female screw members arranged in a state where end faces thereof face each other, and adjacent female screw members are adjacent to each other. A heat insulating structure for buildings, which is connected to each other by stud bolts. 5. The heat insulating structure for a building according to claim 1, 2, 3 or 4, wherein the structural member and the inner support plate are connected via a pair of angle members, and each angle member is an inner member. The second portion of each angle member includes a first portion fastened to the inner support plate along the support plate and a second portion orthogonal to the first portion and along the structural member. The part of (1) is fastened to the structural material by being fastened to each other with the fastening bolts while sandwiching the structural material between them. 6. The heat insulating structure for a building according to claim 5, wherein one of the structural member and the second portion is provided with an elongated hole through which the co-fastening bolt is positionably inserted. Thermal insulation structure of the building. 7. A fastening structure for a support plate for a heat insulating panel, which fastens a pair of support plates for sandwiching a heat insulating panel, wherein a rod-shaped heat insulating resin member having screw holes formed on both end surfaces thereof.
The invention is characterized by including a female screw member formed of a metal reinforcing sleeve fitted to the outer peripheral surface of the resin member, and a connecting bolt penetrating each support plate and screwed into a screw hole of the resin member. Fastening structure of support plate for heat insulation panel. 8. The fastening structure for a support plate for a heat insulating panel according to claim 7, wherein the female screw member is composed of a plurality of female screw members arranged in a state where the end faces are opposed to each other, and the adjacent female screw members are adjacent to each other. Is a fastening structure for a support plate for a heat insulation panel, which is connected to each other by stud bolts.
