Abstract

PROBLEM TO BE SOLVED: To make it possible to eliminate the need for a panel whose type is especially designed for every specification of an insulating material and adjust the erection of an exterior wall on indoor and outdoor sides respectively. SOLUTION: A lathing board 12 is pasted on the indoor side of a frame 11 on the indoor side of an exterior facing panel 5 on which an expandable concrete board 7 is pasted on the outdoor side of a metal-made frame 6 while an interior facing panel 8 provided with an insulation material 13 on the rear surface of the lathing board 12 surrounded with the frame 11, is provided side by side. It is possible to comply with the specification of the insulating material 13 which may vary with an area only by selecting the interior facing panel 8 where the thickness of the insulating material is different. This construction makes it possible to share the exterior facing panel 5 by replacing the interior facing panel 8 and contrive to reduce cost and facilitate inventory management. Since the exterior finishing panel 5 is separated from the interior finishing panel 8, erection adjustment is available based on each construction status on the outdoor side and the indoor side. It is also possible to construct a thick exterior wall within the limit of the thickness direction during transportation time.

Was needed. For this reason, it is necessary to replace each panel only because the specifications of the heat insulating material are different, which leads to an increase in cost, and there is a problem in that the number of types of panels increases and inventory management cannot be facilitated.

Further, since the exterior material and the interior material are integrated, the unevenness of the building cannot be individually adjusted on the outdoor side and the indoor side, and it may not be possible to deal with the construction situation. Further, since the panel is an integral type, the weight of the panel becomes heavy, and there is a problem that a thick outer wall cannot be formed due to the limitation in the thickness direction during transportation. Therefore, an object of the present invention is to provide an outer wall structure that does not require the type of panel for each specification of the heat insulating material, can perform the building adjustment individually on the outdoor side and the indoor side, and can form a thick outer wall.

In the handrail wall of the present invention, a wall base plate is attached to the indoor side of an exterior panel in which a foam concrete plate is attached to the outdoor side of a metal frame, and to the indoor side of the frame. An interior panel provided with a heat insulating material is arranged side by side on the back surface of the wall base plate surrounded by the frame.

In this way, the interior panels are arranged side by side on the interior side of the exterior panel, the wall base plate is attached to the interior side of the frame of the interior panel, and the heat insulating material is provided on the back surface of the wall base plate surrounded by the frame. Since it is provided, it is possible to meet different heat insulating material specifications depending on the region simply by selecting an interior panel having a different heat insulating material thickness. Therefore, the exterior panel can be made common by simply replacing the interior panel, so that the cost can be reduced and the inventory management becomes easy. In addition, since the exterior panel and the interior panel are separated, it is possible to adjust the construction in each of the construction conditions on the outdoor side and the indoor side. In addition, by separating the exterior panel and the interior panel from each other and transporting them, a thick outer wall can be configured within the limitation in the thickness direction during transportation.
