That is, FIG. 1 (a), (b)-FIG. 4 is sectional drawing which shows a construction state. The exterior material A is shown in FIGS. 5 (a), 5 (b) to 7 (a), 7 (b) ((a) is a left end portion and (b) is a partially cutaway perspective view showing a right end portion). Thus, it is the exterior material A which sandwiched the core material 3 which consists of a synthetic resin foam with the surface material 1 and the back surface material 2, for example. 8A to 8C are cross-sectional views showing an example of the end covering material Y for constructing the exterior material A.

As shown in FIGS. 5 (a), 5 (b) to 7 (a), (b), the exterior material A is formed between a surface material 1 made of a long and thin metal plate and a sheet-like back material 2. A male connecting portion formed by sandwiching the core material 3, forming a substantially vertical decorative surface 6, a lower side wall 7 bent inward at the lower end, and an upper side wall 8 bent inward at the upper end, and formed at the lower end in the width direction. 4. It is formed from the female type | mold connection part 5 formed in the upper end. The decorative surface 6 is formed with a recess 6a and a protrusion 6b.

More specifically, the male connecting portion 4 includes an upper edge 9 projecting upward from the lower wall 7 to the back side of the decorative surface 6, an engagement piece 10 having the upper edge 9 bent downward, and an upper edge. 9 and an engagement groove 11 made of an engagement piece 10.

The female connecting portion 5 includes a joint surface 12 with the top end of the upper side wall 8 bent upward, a top surface 13 that projects the top end of the joint surface 12 and projects downward, and a bottom surface 14 that projects by projecting the top end of the top surface 13 upward. And a fitting groove 15 formed from the upper surface 13 and the lower surface 14, a fixing surface 16 protruding further upward from the lower surface 14, and a fitting piece 17 composed of the joint surface 12 and the lower surface 14. P is a sealing material formed to enhance waterproofness.

In FIGS. 1A, 1B, and 2, α is a housing, and β is a fixture.

More specifically, as shown in FIGS. 5 (a), 5 (b) to 7 (a), (b), a waterproof space is provided by providing uneven portions 18 on the joints 12 at the left and right end portions of the exterior material A. It forms γ. The concave-convex portion 18 forms a waterproof space γ in the engaging groove 11 as shown in FIGS. 1A and 1B to FIG. 4, and the engaging groove is shown in FIG. 11 is formed in order to prevent the rainwater R from entering due to the capillary phenomenon in the inside.

More specifically, since a minimal gap is continuously formed in the engagement groove 11 between the conventional exterior materials A, the capillary phenomenon due to wind and rain and the minimal gap in the engagement groove 11 is formed in this minimal gap. Therefore, there is a risk that the rainwater R will run sideways in the direction of the joints and enter the enclosure α. For this reason, it is necessary to form a sealing material P1 such as a back-up material, a caulking material, etc. in order to enhance waterproofness, particularly in a portion where the end covering material Y such as a joint portion is formed.

In order to solve such a weak point, the waterproof space γ is formed by forming the uneven portion 18 on the joint surface 12 at the end of the exterior material A, and the capillary phenomenon in the engagement groove 11 is prevented, The lateral running of the rainwater R is prevented by the waterproof space γ, and the waterproof property is improved.

In addition, although the recessed part is shown as the uneven | corrugated | grooved part 18 in the figure, of course, a convex part may be formed and the uneven | corrugated | grooved part 18 may be formed and the waterproof space (gamma) may be formed. In addition, the sealing material P1 can be formed in the waterproof space γ formed by the concavo-convex portion 18 to enhance the waterproof property. Formation of the sealing material P1 does not block the entire waterproof space γ, and if it is partially formed, the waterproof property can be enhanced while preventing capillary action.

Of course, the concavo-convex portion 18 may be formed on the ground surface 12 as shown in the figure, and may be formed on the upper edge 9 in the engagement groove 11 of the male connecting portion 4, or the concavo-convex portion 18 is formed only on the upper edge 9. The waterproof space γ may be formed to form the waterproof space γ as long as the concave and convex portions 18 are formed in the engagement grooves 11 at both ends of the exterior material A.
