The wall unit 3
Is formed by arranging and connecting a plurality of the heat insulating wall panels P side by side (may be arranged side by side vertically and horizontally).

As shown in FIG. 1, the heat insulating wall panel P has a surface decorative member P2 formed by arranging a plurality of tiles 6 in parallel.
And a panel body P1 disposed on the back side of the surface decorative member P2 and integrated with the surface decorative member P2. The panel body P1 has a frame 7 arranged on the back surface side of the surface decorative member P2 and a surrounding portion S (see FIG. 2C) surrounded by the surface decorative member P2 with respect to the synthetic resin foam. It is configured by forming a filling portion 9 (specifically, a urethane foam). And
Around the connecting portion of the frame 7 with the adjacent panel, a recessed notch A is provided in the synthetic resin foam filling portion 9 so as to form a space for attaching a connecting tool. In the present embodiment, the recessed notch A is configured by embedding a bottomed surrounding member 11 made of foamed resin (for example, foamed styrene) in the synthetic resin foam filled portion 9.

The heat insulating wall panel P is manufactured by the manufacturing method described in detail below. First, as shown in FIG. 2A, a plurality of the tiles 6 are placed side by side on the lower mold 8A so that each surface faces downward, thereby forming the surface decorative member P2. . In addition, a certain gap is provided between the tiles 6, and the gap serves as a joint. A plurality of protrusions 8a for positioning each tile 6 and forming joints are formed in advance on the lower mold 8A, and each tile 6 is fitted between the protrusions 8a to have a predetermined shape. It comes to be arranged in the form.
The plurality of protrusions 8a are formed by inserting pins into some of the plurality of insertion holes formed in the lower mold 8A in advance. Next, as shown in FIG. 2B, a joint closing seal 6A is provided on the back side joint of the surface decorative member P2.
Are glued over the adjacent tiles 6 to close the bottom of the joint. The blockage by the joint blocker seal 6A is for preventing the foamed resin 9A supplied as described later from entering the joint block. Next, Fig. 2 (C)
As shown in FIG. 4, a frame 7 (specifically, a frame made of a metal square tube), which is usually composed of an outer frame and a reinforcing frame, and the recessed notch A are formed on the surface decorative member P2. And the bottomed surrounding member 11 (see FIG. 3) are placed at predetermined positions. The height of the bottomed surrounding member 11 is set to be slightly higher than the height of the frame 7. This is because, as will be described later, when the upper mold 8B is lowered, the frame 7 does not contract in the vertical direction, but the surrounding member 11 with a bottom can contract in the vertical direction. Then, the release resin layer 10 is temporarily fixed to the lower surface of the upper mold 8B facing the lower mold 8A, and the upper mold 8B in the temporarily fixed state is lowered to move to the lower mold 8A side. The frame 7 and the surface decorative member P
A surrounding portion S surrounded by 2 and 2 is formed, and the surrounding portion S is covered with the upper mold 8B via the release resin layer 10. Next, as shown in FIG. 2D, the surrounding portion S
Then, the uncured foamed resin 9A (specifically, a two-liquid mixture of isocyanate and polyol) is supplied through a nozzle 14 inserted into a through hole previously formed in the upper mold 8B. Next, as shown in FIG. 2 (e), after inserting the plug 15 into the through hole instead of the nozzle 14 inserted into the through hole, the foamed resin 9A existing in the surrounding portion S
Is foamed and cured to form a synthetic resin foam filling portion 9 integrated with the surface decorative member P2 and the frame 7. When the frame 7 is placed on the surface decorative member P2, the foam resin 9A for preventing damage of the tile 6 is provided between the outer edge portion of the surface decorative member P2 and the outer frame 7A. It is preferable to interpose the elastic cushioning material 16 that functions to prevent leakage of the material.

According to the panel of the present invention manufactured by such a manufacturing method, the recessed notch A is formed in advance in the synthetic resin foam filled portion 9 by installing the bottomed surrounding member 11. Therefore, the recessed notch A functions as a mounting space for the connecting tool for connecting the adjacent panels. Therefore, the laborious work that was necessary in the past, such as hollowing out the synthetic resin foam filling portion 9 to form the mounting space, becomes unnecessary. Moreover, in this embodiment, since the bottomed surrounding member 11 is made of foamed resin, the bottomed surrounding member 11 itself also exhibits heat insulating property, and the heat insulating property of the panel of the present invention is improved. become.

Next, another embodiment will be described. <1> As shown in FIG. 5, the bottomed surrounding member 1 has the center position (or substantially the center position) of the bottomed surrounding member 11 exactly aligned with the joint position of the tile 6.
Another embodiment in which 1 is arranged is conceivable. The position of the bottomed surrounding member 11 is set as described above for the following reason. That is, in the joint portion of the tile 6, the degree of adhesion between the surface decorative member P2 and the synthetic resin foam filled portion 9 tends to decrease, but the bottomed surrounding member 11 is just attached to the joint of the tile 6. If arranged, the sacrifice that the degree of adhesion between the surface decorative member P2 and the synthetic resin foam filled portion 9 is lowered at the joint portion of the tile 6,
This is because it can be kept as low as possible. <2> In order to form the recessed notch A, as shown in FIG. 6, a metal enclosure member 12 is attached to the frame 7, and in addition to the portion enclosed by the enclosure member 12, the composite Another embodiment is conceivable in which the resin foam filling portion 9 is formed. <3> The surface decorative member P2 is not always formed by arranging a plurality of tiles 6 as in the above-described embodiment. For example, a small number (including one) of a wooden board, a resin board, a natural stone material, an artificial stone material, or the like can be arranged and formed. <4> In the above-described embodiment, no other member is interposed between the space forming member 11 and the surface decorative member P2, and the lower surface of the space forming member 11 directly contacts the surface decorative member P2. However, as shown in FIG. 7, the layered synthetic resin foam filling portion 9 ′ is integrally extended with the synthetic resin foam filling portion 9 between the space forming member 11 and the surface decorative member P2. May be. When the heat insulating wall panel P having the structure of this another embodiment is formed, the space forming member 11 is formed thin in advance in accordance with the desired thickness of the layered synthetic resin foam filled portion 9 '. A spacer 17 for securing a thin space into which the synthetic resin foam can enter may be foam-filled while being interposed between the space forming member 11 and the surface decorative member P2.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
