The eaves-side upper projecting portion 517 of the adjacent heat insulating panel 5 is placed on the upper surface 512 a of the ridge-side lower projecting receiving portion 512 .

As shown in FIG. 4 , the ridge-side upper stepped side surface 513 is located closer to the eaves side (one end side) than the ridge-side lower projecting receiving portion 512 in the ridge-side stepped portion 511 disposed at the other end, and extends upward from the upper surface 512a of the ridge-side lower projecting receiving portion 512. The ridge-side upper stepped side surface 513 is configured by a surface extending upward from the eaves-side end of the upper surface 512 a of the ridge-side lower projecting receiving portion 512 .

As shown in FIGS. 3 and 4 , the first elastic member 52 is not adhered to the eaves-side lower stepped side surface 518 at the eaves-side end portion of the heat-insulating panel 5 arranged at the connecting portion 50 of the adjacent heat-insulating panel 5. The first elastic member 52 is arranged to extend in a direction perpendicular to the inclination direction of the roof 11 along the eaves-side lower stepped side surface 518 formed below the eaves-side upper projecting portion 517. Both ends of the first elastic member 52 in the direction perpendicular to the inclination direction of the roof 11 extend to the outer ends of the second sheet member 55 in the direction perpendicular to the inclination direction of the roof 11 in a state where the second sheet member 55 (described later) is attached to the end portion of the lower surface of the panel body 51 in the direction perpendicular to the inclination direction of the roof 11.
The first elastic members 52 are arranged in pressure contact between the adjacent panel bodies 51 at the connecting portions 50 of the adjacent heat insulating panels 5 . In this embodiment, a foam such as EPDM (ethylene-propylene-diene rubber) is used as the first elastic member 52 .

As shown in FIG. 3 , the first sheet material 53 connects the lower surface of the eaves-side end (one end) of the panel body 51 to the lower surface of the first elastic member 52 at the eaves-side end of the heat-insulating panel 5 arranged at the connecting portion 50 of the adjacent heat-insulating panel 5. The first sheet member 53 is formed in a sheet shape, has a width in the inclination direction of the roof 11, and extends along the edge of the eaves side of the panel body 51 in a direction perpendicular to the inclination direction of the roof 11. The first sheet member 53 has a second sheet member 55 (described later) attached to an end portion of the lower surface of the panel body 51 in a direction perpendicular to the direction of inclination of the roof 11. Both ends of the first sheet member 53 in a direction perpendicular to the direction of inclination of the roof 11 extend to outer ends of the second sheet member 55 in a direction perpendicular to the direction of inclination of the roof 11. The first sheet member 53 is affixed across the outer end portions of the second sheet member 55 in the direction perpendicular to the inclination direction of the roof 11 of the panel body 51 in the direction perpendicular to the inclination direction of the roof 11 .

As shown in FIG. 4, in the tilt direction of the roof 11, the width of the first sheet material 53 is such that the length extending from the eaves-side lower step side surface 518 to the eaves side is longer than the length from the eaves-side lower step side surface 518 of the first elastic member 52 to the eaves-side end. The first sheet material 53 is formed to have a width that protrudes to the eaves side (outside) of the first elastic member 52 .
In a state in which a second sheet material 55 (described later) is attached to the end of the lower surface of the panel body 51 in a direction perpendicular to the inclination direction of the roof 11, the ridge-side portions of the outer ends of the first sheet material 53 in the direction perpendicular to the inclination direction of the roof 11 are overlapped and attached to the eaves-side edge of the second sheet material 55 attached to the lower surface of the panel body 51.

The first sheet material 53 is not attached to the entire bottom surface of the panel body 51 , but is attached across the bottom surface of the eaves-side edge of the panel body 51 and the bottom surface of the first elastic member 52 . In this embodiment, for example, a sheet made of polyethylene or the like is used as the first sheet material 53 . Note that the first sheet material 53 may be attached to the entire lower surface of the panel body 51 . Also, the first sheet material 53 may or may not have a moisture-proof function or a waterproof function.

As shown in FIGS. 2 and 4, the second elastic member 54 is arranged between the side surface 51a of the edge of the panel body 51 of the heat insulating panel 5 in the width direction and the side surface 4b of the rafter 4 in the direction perpendicular to the inclination direction of the roof 11 (the direction intersecting the direction in which the plurality of heat insulating panels 5 are arranged). The second elastic member 54 is arranged to extend in the inclination direction of the roof 11 along the side surface of the end portion in the width direction of the heat insulating panel 5 without being adhered to the side surface 51a of the end portion of the panel body 51 of the heat insulating panel 5. The second elastic member 54 is arranged in pressure contact between the heat insulating panel 5 and the rafters 4 . In this embodiment, a foam such as EPDM (ethylene-propylene-diene rubber) is used as the second elastic member 54 .

As shown in FIG. 4 , the eaves-side end portion 54 a of the second elastic member 54 is arranged in contact with the ridge-side side surface 52 a of the first elastic member 52 while facing the ridge-side side surface 52 a of the first elastic member 52 at a position inside the eaves-side corner portion of the panel body 51 relative to the end portion in the direction perpendicular to the inclination direction of the roof 11 . Note that the eaves-side end portion 54a of the second elastic member 54 is not limited to being in contact with the ridge-side side surface 52a of the first elastic member 52 . The eaves-side end 54a of the second elastic member 54 may not contact the ridge-side side 52a of the first elastic member 52, and a small gap may be formed between the eaves-side end 54a of the second elastic member 54 and the ridge-side side 52a of the first elastic member 52.

As shown in FIG. 2 , the second sheet member 55 connects the lower surface of the edge of the panel body 51 in the width direction (the width direction of the panel body 51) of the panel body 51 in the direction perpendicular to the inclination direction of the roof 11 (the width direction of the panel body 51) and the bottom surface of the second elastic member 54. The second sheet material 55 is formed in a sheet shape and has a width in a direction orthogonal to the inclination direction of the roof 11, and extends in the inclination direction of the roof 11 along an end portion of the panel body 51 in a direction orthogonal to the inclination direction of the roof 11. The second sheet material 55 has a ridge-side end extending to the ridge-side side surface of the ridge-side lower projecting receiving portion 512 of the panel body 51 , and an eaves-side end extending to the eaves-side lower stepped side surface 518 of the panel body 51 . The second sheet material 55 is between the ridge-side end and the eaves-side end on the lower surface of the panel body 51, and is attached across the ridge-side side surface of the ridge-side lower projecting receiving portion 512 of the panel body 51 and the eaves-side lower step side surface 518.

As shown in FIG. 4 , the width of the second sheet material 55 in the direction perpendicular to the inclination direction of the roof 11 (the width direction of the panel body 51) is such that the length extending outward from the side surface 51 a of the panel body 51 of the heat insulating panel 5 is longer than the length of the second elastic member 54 from the side surface 51 a of the panel body 51 of the heat insulating panel 5 to the outer end. The second sheet material 55 is formed to have a width that protrudes outward in the direction perpendicular to the inclination direction of the roof 11 relative to the second elastic member 54 .

The second sheet material 55 is not attached to the entire lower surface of the panel body 51, but is attached across the lower surface of the end portion of the panel body 51 in the direction orthogonal to the tilt direction of the roof 11 and the lower surface of the second elastic member 54. In this embodiment, a sheet made of polyethylene or the like is used as the second sheet member 55, for example. The second sheet material 55 may be attached to the entire bottom surface of the panel body 51 . Also, the second sheet material 55 may or may not have a moisture-proof function or a waterproof function.

Next, the construction method of the laying structure of the heat insulating panel 5 will be described. FIG. 5 is a perspective view explaining a construction method of the laying structure of the heat insulating panel 5. FIG. 6A and 6B are diagrams for explaining a construction method for connecting adjacent heat insulating panels 5, FIG. 6A is a diagram showing before connection, and FIG. 6B is a diagram showing after connection. 7A and 7B are diagrams illustrating a construction method for installing the heat insulating panel 5 next to the rafters 4. FIG. 7(a) is a diagram showing before installation, and FIG. 7(b) is a diagram showing after installation.

In the construction method of this embodiment, as shown in FIG. 5, a method of connecting the heat insulating panels 5 adjacent in the inclination direction of the roof 11 while arranging the heat insulating panels 5 between the rafters 4 will be described.

In the direction of inclination of the roof 11, the plurality of heat insulating panels 5 are arranged along the direction of inclination of the roof 11, as shown in FIG. The heat insulating panel 5 is supported by the eaves girder 31 on the eaves side, by the purlin 33 midway in the inclination direction of the roof 11, and by the ridge beam 32 on the other end on the ridge side. One end on the eaves side of the heat insulating panel 5 closest to the eaves is connected to the anti-rollover 34 . Adjacent heat insulating panels 5 are connected at a connecting portion 50 between the heat insulating panel 5A on the eaves side (one side) and the heat insulating panel 5B on the ridge side (other side).

In the present embodiment, in the following description, for example, the laying structure of adjacent heat insulating panels 5 will be described. However, the laying structure in which one end portion of the eaves side of the heat insulating panel 5 closest to the eaves is placed on the anti-rolling device 34 also has the same structure as the laying structure of the adjacent heat insulating panel 5 . Therefore, the description of the laying structure of the adjacent heat insulating panel 5 described below can be used for the description of the laying structure in which one end of the heat insulating panel 5 closest to the eaves is placed on the anti-rollover 34 . When one end of the eaves side of the thermal insulation panel 5 closest to the eaves is connected to the anti-roll 34, the anti-roll 34 corresponds to the ridge-side lower projecting receiving portion 512 of the panel body 51 of the insulating panel 5 and constitutes a receiving portion.

As shown in FIG. 5, for example, when the eaves-side heat insulation panel 5A is laid and the adjacent ridge-side heat insulation panel 5B is laid, the eaves-side upper protrusion 517 of the adjacent ridge-side heat insulation panel 5B is moved from the upper side to the lower side, and the eaves-side upper protrusion 517 of the ridge-side heat insulation panel 5B is placed on the upper surface 512a of the ridge-side lower protrusion receiving portion 512 of the eaves-side heat insulation panel 5A. The first sheet material 53 is once brought into contact with the upper surface 512a of the side lower projecting receiving portion 512, and the first sheet material 53 is bent upward to press the first elastic member 52 between the side surface of the ridge-side lower projecting receiving portion 512 and the eaves-side lower stepped side surface 518.

Specifically, as shown in FIGS. 6A and 6B, in a state where the eaves side heat insulation panel 5A is laid, the ridge side heat insulation panel 5B is dropped from the upper side to the lower side with respect to the eaves side heat insulation panel 5A in the adjacent heat insulation panel 5. As a result, the eaves-side lower surface of the first sheet material 53 once contacts the upper surface 512a of the ridge-side lower projecting receiving portion 512 of the eaves-side heat insulation panel 5A, and the first sheet material 53 is bent upward along the eaves-side lower step side surface 518 of the ridge-side heat insulation panel 5B. By bending the first sheet member 53 upward along the eaves-side lower stepped side surface 518, the first elastic member 52 is pressed against the eaves-side lower stepped side surface 518 so as to turn about 90°, and the first elastic member 52 is pressed between the side surface of the ridge-side lower protrusion receiving portion 512 of the panel body 51 of the eaves-side heat insulating panel 5A and the eaves-side lower stepped side surface 518 of the panel body 51 of the ridge-side heat insulating panel 5B. It is sandwiched in a state of being in contact.

As a result, the first elastic member 52 can be placed in pressure contact between the side surface of the ridge-side lower projecting receiving portion 512 of the heat-insulating panel 5A and the eave-side lower step side surface 518 of the heat-insulating panel 5B simply by dropping the ridge-side heat-insulating panel 5B from the upper side to the lower side with respect to the eave-side heat-insulating panel 5A with the eave-side heat-insulating panel 5A laid, as shown in FIG. Therefore, the ridge-side heat insulation panel 5B can be easily laid on the adjacent eave-side heat insulation panel 5A in a state in which airtightness and watertightness are ensured.

Here, in this embodiment, the plurality of heat insulating panels 5 are laid in order from the lower side to the upper side in the inclination direction of the roof 11 . Therefore, by arranging the heat insulation panel 5A on the eaves side (lower side in the inclination direction of the roof 11) and the heat insulation panel 5B on the ridge side (upper side in the inclination direction of the roof 11), the eaves side upper protrusion 517 of the ridge side heat insulation panel 5B can be placed on the ridge side lower protrusion receiving section 512 of the eaves side heat insulation panel 5A. Thus, a plurality of heat insulating panels 5 can be easily laid by simply moving the adjacent ridge side heat insulating panel 5B from the upper side to the lower side and dropping it into the eave side heat insulating panel 5A.

In addition, in the direction orthogonal to the inclination direction of the roof 11, the thermal insulation panel 5 is arranged between the rafters 4 spaced apart in the direction orthogonal to the inclination direction of the roof 11.

As shown in FIG. 5, for example, when laying the heat insulating panel 5 with the rafters 4 laid, the side surface 51a of the panel body 51 of the heat insulating panel 5 is arranged along the side surface 4b of the rafter 4 extending in the longitudinal direction. In this case, the insulation panel 5 is moved from the upper side to the lower side along the side 4B of the rafter 4, and the insulation panel 5 is placed on the side 4b of the rafter 4, so that the second seat material 55 is turned into the upper surface 4a of the rafter 4, and the 2nd seat material 55 is bent to the upper side. The second elastic member 54 is placed between the side 4b of rafter 4 and the side 51a of the end of the width direction of the panel 51 of the insulation panel 5.

Specifically, as shown in FIGS. 7(a) and 7(b), with the rafters 4 laid down, the insulation panels 5 are dropped from above along the longitudinal side surfaces 4b of the rafters 4 from above. As a result, the outer lower surface of the second sheet member 55 contacts the upper surface 4a of the rafter 4, and the second sheet member 55 is bent upward along the side surface 51a of the panel main body 51 in the width direction.
