The sheet-like elastic material 13 is attached to the face material 2 by adhesion or double-sided tape. As the sheet-like elastic material 13, it is preferable to use a semi-independently foamed elastic material made of EPDM resin in terms of elasticity and airtightness. It can be used as a sheet-like elastic material 13.

  5 and 6, reference numeral 14 denotes a wooden block embedded in one side of the foamed resin material 3 in order to fix the foamed resin material 3 to the face material 2. A plurality of wooden blocks 14 ( 3 in this example). The foamed resin material 3 is attached to the face material 2 by a fixture 15 such as a nail or a screw that is screwed into the wooden block 14 from the outdoor side surface of the face material 2 through the face material 2.

As shown in FIG. 7A, the panel 1 is attached so that the foamed resin material 3 fits into a shaft assembly 9 including columns 4, inter-columns 5, and the like. Then, as shown in FIG. 7B, the panel 1 is fixed by fixing both sides, the center, and the like of the face material 2 to the frame structure such as the pillar 4 and the interposition pillar 5 by the fixture 16 such as a nail or a screw. Is attached to the shaft assembly 9.

  When the panel 1 is mounted in this way, as shown in FIG. 8, the second elastic member 10 contracts while the airtight sheet 6 slides on the prospective surface 17 of the shaft assembly such as the pillar 4 and the like. The airtight sheet 6 is pressed against the prospective surface 17 by the elasticity of the elastic material 2. In a state after the panel 1 is attached to the shaft assembly 9, the end portion of the sheet-like second elastic member 10 is positioned on the outdoor side by a width indicated by L from the end portion of the airtight sheet 6. Further, the end portion of the first elastic member 8 coincides with the end portion of the second elastic member 10 or is located further on the outdoor side than the end portion of the second elastic member 10 as illustrated.

  As shown in FIG. 2, the airtight sheet 6 is bent in an L shape in the outdoor side and fixed to the second elastic member 10 at the bottom of the foamed resin material 3.

As shown in (B), it is possible to realize a structure in which the elastic members 8 and 10 are in close contact with each other at the edges when the panel 1 is attached. It is not necessary to add a separate member dedicated to the corner as in the case of configuring the above, and airtightness in the corner can be ensured.

  Moreover, in this Embodiment, since the foamed resin material 3 as a heat insulating material was provided in the face material 2 without providing a wooden frame, weight reduction can be achieved and construction can be facilitated. Moreover, since the wooden frame with higher thermal conductivity than the foamed resin material 3 can be eliminated and the thick foamed resin material 3 can be used at the same cost, the heat insulation can be improved. In addition, since the frame assembly such as the spacer 5 is not provided on the face material side, as shown in FIG. 7A, even if there is a warp on the face material 2 side, it is easy to correct this warp during construction. Become.
