[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention maximizes deterioration of quality and yield in an outer wall structure in which lateral joints are formed between upper and lower outer plates by installing a plurality of outer plates in the height direction. The present invention relates to an outer wall structure capable of efficiently forming a good-looking outer wall in which the pitch intervals of the horizontal joints are freely changed while suppressing the same.

2. Description of the Related Art In recent years, houses of a dry method using panel bodies such as wall panels and floor panels have become widespread. Then, for example, as shown in FIG. 7, a plurality of laterally long rectangular exterior plates b are provided on an outer wall foundation a composed of a wall panel or the like supported on a frame or a frame, for example, as shown in FIG. It may be formed by being installed in the height direction. At this time, the lateral joint c is formed between the upper and lower exterior plates b.

On the other hand, an ALC plate such as lightweight cellular concrete is generally used for the exterior plate b. This ALC plate is a large block obtained by casting an ACL raw material with a piano wire or the like. A slice is cut into a plate having a predetermined size, and the plate is heated in a curing pot (autoclave curing) to form a high-strength ALC plate in which ALC is crystallized. After that, joint processing and surface treatment according to the application are performed to form the exterior plate b.

However, in such an exterior plate b, since the size and performance of the curing pot are restricted, the height H thereof is restricted to the optimum range for the curing quality and the like. . Therefore, in the outer wall using the exterior plate b, the joint pattern becomes monotonous such that the pitch intervals P of the lateral joints c become uniform, and the appearance of the house cannot be sufficiently enhanced.

Therefore, in recent years, in order to improve the design, it has been desired that the pitch interval P of the lateral joint c be irregularly changed to complicate the joint pattern.

However, when a plurality of types of exterior plates b having different heights H are formed, the curing quality is impaired due to the restriction of the curing pot, and the yield and the production efficiency are reduced. In addition, the total height H greatly changes depending on how to combine a plurality of types of exterior plates b, which makes it difficult to select a combination of exterior plates for obtaining an outer wall having a predetermined height, and also makes inventory management difficult.

The present invention has been devised in view of the above situation, and uses a plurality of sets of set division pieces obtained by cutting a reference plate manufactured at a reference height into a plurality of pieces in the height direction. Based on the construction of the exterior plate, the pitch intervals of the horizontal joints were changed without inducing yield or quality deterioration, and while improving the complexity of selection of the combination of exterior plates and inventory control. It is intended to provide an outer wall structure capable of efficiently forming an outer wall having a complicated joint pattern.

[0008]

In order to achieve the above-mentioned object, the invention of claim 1 of the present application is such that a plurality of exterior plates are arranged side by side in the height direction on an outer wall substrate, and fixed to the upper and lower exterior plates. An outer wall structure of an outer wall having a horizontal joint formed between them, the exterior plate is a reference plate manufactured at a reference height, by cutting into a plurality of pieces in the height direction, the total height is the reference height. It is characterized in that a plurality of sets of the set divided pieces are used and the heights of the exterior plates arranged in the vertical direction are different.

According to a second aspect of the invention, the exterior plate is
It is characterized in that the divided set piece or the reference plate is used in the range of the outer wall excluding the height range equal to or less than the reference height of one reference plate.

Further, in the invention of claim 3, the reference plate is
