You.

  Next, the operation of the heat insulating sheet 3 and the wall panel 100 will be described. FIG. 6 is a schematic diagram illustrating an operation state in which the topsheet 33 is separated from the heat insulating material sheet 3. The operator peels off the peripheral edge 33a of the top sheet 33 located on the upper end side of the heat insulating material sheet 3. The peripheral portion 33a can be easily peeled off by the first cut portion 34a. The upper end side of the heat insulating material sheet 3 is adhered to the core material 12 on the back surface side of the base 1 by the adhesive layer 32 exposed in a state where the peripheral edge portion 33a on the upper end portion is peeled off.

  Next, the operator peels off the peripheral portion 33b of the top sheet 33 located on the side of the heat insulating material sheet 3. The peripheral portion 33b can be easily peeled off by the second cut portion 34b. The heat insulating material sheet 3 is laterally attached to the core material 12 by the adhesive layer 32 which is exposed in a state where the side peripheral portion 33b is peeled off. Next, the operator peels off the peripheral portion 33a of the top sheet 33 located on the lower end side of the heat insulating material sheet 3. The peripheral portion 33a can be easily peeled off by the first cut portion 34a. The lower end side of the heat insulating material sheet 3 is attached to the core material 12 by the adhesive layer 32 which is exposed in a state where the peripheral edge portion 33a on the lower end side is peeled off. By proceeding with such a procedure, the peripheral sheet of the top sheet 33 can be peeled off part by part and the work can be proceeded, so that the work of attaching the heat insulating material sheet 3 to the base 1 is further facilitated. In addition, since the peripheral portion of the top sheet 33 may be linearly peeled four times corresponding to the four sides, work efficiency is high.

  As shown in FIG. 2 and FIG. 5, the wall panel 100 is in a state in which the peripheral portion of the heat insulating material sheet 3 is adhered to the base 1, and the center portion is floated by the mounting bracket 2, and the air layer 4 is formed. . The heat retention of the wall panel 100 is enhanced by the formation of the air layer 4. In the heat insulating material sheet 3, the central portion 33c of the top sheet 33 remains at a position corresponding to the mounting bracket 2. For this reason, although the fitting 2 is in contact with the heat insulating material sheet 3 but is not adhered, the fitting 2 can move in the in-plane direction of the core material 12.

  FIG. 7 is a schematic diagram illustrating an operation state of attaching the storage rack 60 to the wall panel 100. When attaching the storage rack 60, the operator inserts the screws 60a into the through holes provided in the storage rack 60 and the base 1, and turns the screws 60a with a tool. While the operator turns the screw 60a several times, the tip of the screw 60a starts to screw into the female screw of the nut 22 of the mounting bracket 2. Since the mounting member 2 can be moved in the in-plane direction of the core member 12 by the cushioning member 23, the tip of the screw 60 a is easily screwed into the female screw of the nut 22.

  When the operator tightens the screw 60a, the cushioning material 23 of the mounting bracket 2 is compressed, while the tip of the screw 60a protrudes from the nut 22.

Further, since the core member 12 and the heat insulating material sheet 3 are not bonded, the mounting member 2 can be moved in the in-plane direction by the cushioning material 23. Furthermore, since the air layer 4 is formed between the core material 12 and the heat insulating material sheet 3, the heat insulating property is improved.

  Further, the heat insulating sheet body 31 is rectangular, and the cut 34 has a first cut 34a along the short direction and a second cut 34b along the long. In the cut 34, a first cut portion 34a is provided over the entire width, and a second cut portion 34b is provided between the first cuts 34a. This allows the work to proceed by peeling off the peripheral edge of the top sheet 33 for each part, so that the work of attaching the heat insulating material sheet 3 to the base 1 is further facilitated. In addition, since the peripheral portion of the top sheet 33 may be linearly peeled four times corresponding to the four sides, work efficiency is high.

  Further, the wall panel 100 includes the heat insulating material sheet 3 having the above-described characteristics and the base 1. The heat insulating material sheet 3 is attached to the base 1 by peeling off the peripheral edge of the top sheet 33 by the cut 34.

The heat insulating material sheet 3 is adhered to the core material 12 of the base 1 while the peripheral edge portion 33a located on the side of the heat insulating material sheet 3 and the peripheral edge portion 33b located at the lower end portion are sequentially peeled off.

  By proceeding in such a procedure, the peripheral sheet of the top sheet 33 can be peeled off part by part, and the work can be proceeded, so that the work of attaching the heat insulating material sheet 3 to the base 1 is further facilitated. In addition, since the peripheral portion of the top sheet 33 may be linearly peeled four times corresponding to the four sides, work efficiency is high. In addition, when the above-described embodiment is combined with the present modification, any one of the first cut portion 34a and the second cut portion 34b is provided over the entire width of the top sheet 33 of the heat insulating material sheet 3. That is, the other cut portion is provided between the one cut portions.
