2. Description of the Related Art As a method for manufacturing a heat insulating panel for a wall of this type, there is an invention described in, for example, Japanese Patent Laid-Open No. 4-124344. The invention is, so to speak, a horizontal upside-down manufacturing method, in which the ceramic porcelain plate as the finishing material is turned upside down on the bottom plate of the box form, that is, the outer surface is faced down, and the rebar is laid on top of it. The net is installed by mounting its corresponding part on each ceramic porcelain plate, the mortar layer is formed by casting and the heat insulating plate is superposed and mounted, and on top of that, the concrete layer after the required reinforcement is placed. It is a method of manufacturing a heat insulating panel for a wall by forming by casting.

[0003]

This manufacturing method has a serious drawback in that it cannot be manufactured while visually observing the alignment of the finishing materials that will form the outer surface of the product. That is, even if there is an inconvenience such as the occurrence of unevenness or undesired gaps in the already laid finishing material after once installing and setting the reinforcing bar net or before hardening the mortar layer, Since the finishing material is on the underside, it can no longer be fixed.

In order to solve such a drawback, the applicant can call the method of standing spraying,
In other words, we have developed and provided a manufacturing method in which a reinforcing net is fixed upright on the bottom plate, a finishing material such as ceramic porcelain plate is mounted and fixed on one side, and a synthetic resin heat insulation layer and a concrete layer are sequentially formed on the other side. Yes (Japanese Patent Application No. 3-351)
No. 291).

However, although this standing-up spraying manufacturing method allows the manufacturing process to proceed while visually observing the alignment state of the finishing material and appropriately correcting it, in comparison with the above-mentioned horizontal reverse-casting manufacturing method, the standing-up of the reinforcing bar net is performed. The workability is not always good because it becomes an unstable construction method in which the support, the synthetic resin heat insulation layer and the concrete layer are sprayed and formed.

The inventor has conducted extensive studies to improve such a situation, and has completed the present invention. It takes advantage of the above-mentioned horizontal reverse casting manufacturing method while visually checking the alignment state of finishing materials. However, it can be corrected appropriately.

[Means for Solving the Problems]

In the method for manufacturing a wall heat insulating panel of the present invention, a concrete layer 4 is formed by casting, a heat insulating plate 5 is superposed on the concrete layer 4, and a reinforcing net 6 is placed on the heat insulating plate 5. Is laid and laid, and mortar is cast on the heat insulating plate 5 to a thickness such that the reinforcing bar net 6 is buried, to form a mortar layer 12, and then a finishing material such as a ceramic porcelain plate 13 is formed. While being pressed against the mortar layer 12, the horizontal bar fitting portions 14 and 15 of the finishing material are fitted to the horizontal bar 8 of the reinforcing bar net 6 to be attached and mounted on the reinforcing bar net 6. In the above, when the reinforcing bar net 6 is fastened to the anchor bolt 3 standingly supported on the concrete layer 4, the concrete layer 4, the heat insulating plate 5, and the reinforcing bar net 6 can be integrated, which is preferable in terms of strength and the like.

[0009]

The present invention is basically a concrete layer, a heat insulating plate,
The reinforcing bar net and the mortar layer are sequentially laminated, and finally, while the finishing material such as a ceramic porcelain plate is pressed against the mortar layer, the horizontal reinforcing bar fitting portion of the finishing material is fitted to the horizontal reinforcing bar of the reinforcing bar net, thereby forming the reinforcing bar net. As in the case of the stand-up spraying manufacturing method, the alignment state of the finishing material that forms the outer surface of the product can be visually observed from the outside and appropriately corrected. However, unlike the case of the stand-up spraying manufacturing method, the desired product can be easily and reliably manufactured without the unstable operations of standing up the reinforcing bar net, spraying the synthetic resin heat insulating layer and the concrete layer.
