イン的にズレて見えるという問題があつた。(Background Art) Conventional exterior panels have been generally provided with a groove portion D on the surface B side, which is connected to a tapered surface H, over the entire length of the horizontally long exterior panel body A as shown in Figures 1 and 2. However, in order to cut the exterior panel body A from the surface B side with a rotary cutter that matches the shape of this groove portion D, the thickness _T1 ,
If _T2 varies, the groove width A will differ, and the groove width _A1 will be
A _2. Therefore, when the side end face of the exterior plate is abutted, there is a problem that the groove width A looks misaligned in terms of design.

る。(Purpose of the invention) The present invention was made in view of the above-mentioned background technology, and its purpose is to provide a horizontal step at the intersection of the tapered surface and the surface of the groove so that the groove can be The purpose is to provide an exterior plate whose width is always constant.

（考案の開示）以下、本考案の一実施例に係る第３図乃至第７
図に基づいて説明する。(Disclosure of the invention) Hereinafter, Figs. 3 to 7 according to an embodiment of the invention will be described.
This will be explained based on the diagram.

第３図及び第４図において、Ａは石綿セメント

３の下辺から下方に向つてテーパー面４を形成し
このテーパー面４と表面２との交叉部５に約１mm
の水平段部６を設けた外装板である。 In FIGS. 3 and 4, A indicates a groove portion having a substantially U-shaped longitudinal section on the surface 2 side in the longitudinal direction of the exterior board main body 1 made of asbestos cement board, calcium silicate board, pulp-mixed cement board, etc. 3, and a tapered surface 4 is formed downward from the lower side of the groove 3, and the intersection 5 between the tapered surface 4 and the surface 2 has a diameter of approximately 1 mm.
This is an exterior plate provided with horizontal step portions 6.

尚、この外装板Ａの溝部形状は第５図のように
テーパー面４を上方に設けるようにしてもよく、
要するにテーパー面４と表面２との交叉部５に水
平段部６を形成すれば良い。 Note that the groove shape of this exterior plate A may be such that the tapered surface 4 is provided upward as shown in FIG.
In short, a horizontal step 6 may be formed at the intersection 5 of the tapered surface 4 and the surface 2.

したがつて、外装板Ａの溝部３を形成するには
溝部３及び水平段部６の形状に沿つた第６図のよ

決り部を重ね合わせて施工する。 Therefore, in order to form the groove part 3 of the exterior plate A, it is sufficient to cut the groove part 3 and the horizontal step part 6 with a rotary cutter 7 as shown in FIG.
Even if T ₁ and T ₂ (shaded areas in the figure) vary, the groove width W remains constant. For this reason, even if the side end surfaces of the exterior plates are abutted and fixed together as shown in Figure 7, the groove width W
is constant, which is good in terms of design. Note that the construction is carried out by overlapping the lower facing part of the upper exterior plate A on the upper part of the lower exterior plate A.

（考案の効果）以上のように、本考案は溝部のテーパー面と表

水平段部によつて板厚がばらついても溝巾が常に
一定となりデザイン的にも良好なものである。(Effect of the invention) As described above, the present invention provides a horizontal step at the intersection of the tapered surface and the surface of the groove, so even if the plate thickness varies, the groove width remains constant due to this horizontal step. It is constant and has a good design.
