Abstract

The invention is intended to reduce heat accumulation in the heat insulator provided around the periphery of the living room of a house structure, thereby achieving simplification of a construction work, energy-saving, and rationalization in maintaining the living environment, and by covering the external face of the heat insulators (2) disposed around the periphery of partition sheet members surrounding the living room, such as the roof, ceiling, wall, and so forth, with the heat shielding members (1) provided with the heat reflection foil, so that radiant heat which will otherwise heat up the heat insulators (2) can be blocked, and heat accumulation in the heat insulators (2) can be reduced.

Claims

1. A thermal insulation structure of a house comprising a heat insulator (2) in a board form, disposed at suitable spots on the inner face of a roof (4) of the house, and on the outside face of partition sheet members of the house, such as a ceiling (3), walls, and so forth, surrounding a living room (R), respectively, and a heat shielding member (1) disposed on the outside face of the respective heat insulators (2) in the board form, made up of a plurality of sheets (11, 12, 13) of which at least the upper sheet (11) is provided with a heat reflection foil (M) on the upper face thereof, wherein respective spaces (S) of an air layer are formed between the respective sheets with a group of stand-up pieces (14, 15), thereby mitigating heat accumulation in the respective heat insulators (2) by the effect of the respective heat shielding members (1).

2. The thermal insulation structure according to claim 1, wherein at least the upper sheet (11) and the sheets (13) of the next layer have the heat reflection foil (M) on the upper face thereof.

3. The thermal insulation structure according to claim 1 or 2, wherein the respective spaces (S) of an air layer of the heat shielding member (1) have an opening enabling ventilation in the longitudinal direction and the heat shielding member (1) is disposed so that both ends of the opening are not closed.

4. The thermal insulation structure according to any of claims 1 to 3, wherein the heat insulator (2) is a wooden heat insulator such as an insulation board, and so forth, and the respective sheets of the heat shielding member (1) are made of paper.

5. The thermal insulation structure according to any of claims 1 to 4, wherein the heat shielding member (1) is fixedly attached beforehand to the heat insulator (2)

6. A heat shielding member including at least an upper sheet (11), and a lower sheet (12), and a heat reflection foil (M) laminated to the upper face of at least the upper sheet (11), and respective spaces (S) of an air layer formed between the respective sheets with a group of stand-up pieces (14, 15), thereby forming a structure wherein the respective sheets can be pressed in contact with each other, and stacked by laying down the group of the stand-up pieces (14, 15).

7. The heat shielding member according to claim 6, wherein the upper faces of the upper sheet (11) and the sheets (13) of the next layer are provided with the heat reflection foil (M).

8. The heat shielding member according to claim 6 or 7, wherein the group of stand-up pieces (14, 15) are securely attached to the upper sheet (11) and lower sheet (12) at bent up faces (14′

, 15′

) provided at the opposite ends thereof, and freely bendable at bent-up parts (r).

9. The heat shielding member according to any of claims 6 to 8, wherein the intermediate sheets (13) are securely attached to the stand-up pieces (14, 15) by bent-up faces (13′

) at both ends and freely bendable at bent-up parts (r).

10. The heat shielding member according to any of claims 6 to 9, wherein the underside face of the lower sheet (12) is fixedly attached to the upper face of the heat insulator (2) in the board form.

11. The heat shielding member according to claim 10, wherein the underside face of the lower sheet (12) is fixedly attached to the heat insulator (2) by a bonding strength after solidification bonding due to foam molding of the rigid urethane foam heat insulator (2),

12. The heat shielding member according to claim 10, wherein the wooden board heat insulator (2) is used as the board heat insulator (2).
