DETAILED DESCRIPTION OF THE INVENTION

[0008] A horizontal exterior wall panel according to one embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1(A), the exterior wall 1 is composed of multiple horizontal exterior wall panels 10. The multiple horizontal exterior wall panels 10 are arranged in the up-down direction (vertical direction) and left-right direction (horizontal direction). The vertical and horizontal ends of each exterior wall panel 10 are fitted together. Each exterior wall panel 10 has the same configuration, is a plate-like shape that is long in the horizontal direction, and is fixed to vertical furring strips 80 with screws (not shown). The vertical furring strips 80 each extend vertically and are parallel to each other so as to be aligned horizontally. The exterior wall panel 10 is made of metal (for example, galvalume steel sheet (registered trademark)) and is integrally formed by pressing a metal sheet.

[0009] As shown in Figures 2(A) and 3(A), the horizontal exterior wall panel 10 comprises a main body wall portion 11 having a plurality of recesses 16, a side insertion portion 12 having a plurality of protrusions 15 and recesses 17, an upper mating portion 13, a lower mating portion 14, an inserted portion 18, a folded portion 19, and a screw-fixed wall portion 21.

[0010] (Main body wall 11) 3(A), the main body wall 11 has a rectangular plate shape that is long in the horizontal direction. The main body wall 11 is inclined in the vertical direction so as to approach the vertical furring strips 80 as it extends upward. A plurality of recesses 16 are formed on the upper surface of the main body wall 11 (the surface opposite the back surface facing the vertical furring strip 80). The recesses 16 (four in this example) are aligned vertically and extend horizontally. The recesses 16 are formed across the entire horizontal area of ​​the main body wall 11. As shown in Figure 2 (B), each recess 16 has a semicircular hole shape that opens in a direction away from the vertical furring strip 80. The vertical width of each recess 16 is formed to be smaller than the spacing between the recesses 16. As shown in Figures 1(A) and 3(C), each recess 16 of an exterior wall panel 10 (e.g., exterior wall panel 10a) is formed in a position where it is covered by the lower end of a horizontally-attached exterior wall panel 10 (e.g., exterior wall panel 10c) adjacent to the exterior wall panel 10 on the upper side. Each recess 16 is configured to allow rainwater that has entered the gap Sp (see Figure 2(B)) between the exterior wall panels 10a, 10c to escape laterally to the lateral insertion portion 12, and to suppress the occurrence of capillary action in which moisture is absorbed into the gap Sp.

[0011] (Side insertion part 12) As shown in Fig. 3(A), the lateral insertion portion 12 is located at the right end in the lateral direction of the main body wall portion 11. The lateral insertion portion 12 is flat and fits along the main body wall portion 11, is located behind the main body wall portion 11 (towards the vertical furring strip 80), and is connected to the main body wall portion 11 via a step portion 11s. The lateral insertion portion 12 is configured so as to be insertable into the insertion receiving portion 18 of the horizontally adjacent horizontal exterior wall panel 10d (see Figs. 3(A) and (B)). To enable this insertion, the vertical length of the lateral insertion portion 12 is formed shorter than the vertical length of the main body wall portion 11.

[0012] As shown in Figure 3(A), the upper end and right end of the side insertion section 12 are formed with raised edge portions 12a, 12b that stand upright toward the front side of the side insertion section 12. The height of the raised edge portions 12a, 12b relative to the surface of the side insertion section 12 is lower than the height of the step portion 11s relative to the same reference. The raised edge portions 12a, 12b are formed to prevent rainwater from flowing toward the vertical furring strip 80.

[0013] 3(A), a plurality of recesses 17 are formed on the upper side of the surface of the side insertion portion 12. The recesses 17 (four in this example) have the same shape as each of the recesses 16 described above and are formed on extensions of each of the recesses 16. The recesses 17 are formed between the step portion 11s and the raised edge portion 12b across the entire lateral area of ​​the side insertion portion 12.

[0014] A plurality of (three in this example) protrusions 15 are formed on the surface of the lateral insertion portion 12, aligned in the horizontal direction and extending in the vertical direction. The plurality of protrusions 15 are parallel to each other and positioned below the plurality of recesses 17. The upper ends of the plurality of protrusions 15 are positioned away from the plurality of recesses 17, and the lower ends of each protrusion 15 reach the lower end of the lateral insertion portion 12. The protrusions 15 are spaced at equal distances between the raised edge portion 12b and the step portion 11s. As shown in Figures 4(A) and (B), the front surface of the protrusion 15 of the side insertion portion 12 is configured to be able to abut against the back surface of the main wall portion 11 of the horizontal exterior wall panel 10 inserted into this side insertion portion 12. Each protrusion 15 has a generally U-shaped cross section (more precisely, a shape that follows the three sides other than the base of a trapezoid) that opens toward the back side, and the lateral width of each protrusion 15 is formed smaller than the spacing between the protrusions 15. Drainage channels 15a are formed between each protrusion 15. The height of each protrusion 15 relative to the surface of the side insertion portion 12 is greater than the height of the edge erection portions 12a, 12b relative to the same reference. The drainage channel 15a is formed to guide rainwater that has entered the gap Sk between the side insertion portion 12 and the main body wall portion 11 (see FIG. 4(B)) downward along each of the protrusions 15.

[0015] As shown in FIG. 2(A), the upper fitting portion 13 is formed by folding back the entire upper end of the main body wall portion 11 to the rear side of the main body wall portion 11. The upper fitting portion 13 is formed so that the lower fitting portion 14 of the adjacent horizontal exterior wall panel 10c on the upper side can be fitted therein. The upper fitting portion 13 has a first U-shaped portion 13a that opens downward and a second U-shaped portion 13b that opens upward. The second U-shaped portion 13b is located on the back side of the first U-shaped portion 13a and is formed continuous with the first U-shaped portion 13a. The opening width of the first U-shaped portion 13a is formed longer than the opening width of the second U-shaped portion 13b. The screw-fixed wall portion 21 extends upward from the end of the opening of the second U-shaped portion 13b that is farthest from the first U-shaped portion 13a. The screw-fixed wall portion 21 is located above the first U-shaped portion 13a. The screw-fixed wall portion 21 has a folded portion 21a where the upper end of the screw-fixed wall portion 21 is folded downward and toward the front side.

[0016] The folded portion 19 is folded back from the entire lower end of the main body wall portion 11 to the rear side of the main body wall portion 11 and is generally L-shaped when viewed from the side. The upper end of the folded portion 19 is connected to the lower fitting portion 14. The lower fitting portion 14 is located above the lower end of the main body wall portion 11 and faces the rear surface of the main body wall portion 11. As shown in Figure 2(C), the lower fitting portion 14 has a generally U-shape that opens downward and is configured to be able to fit into the first U-shaped portion 13a of the exterior wall panel 10b. The lower fitting portion 14 has folded-back portions 14a formed by folding back the ends of the opening of the lower fitting portion 14 that are farther from the main body wall portion 11 upward and to the rear. The folded-back portions 14a are located within the second U-shaped portion 13b.

[0017] As shown in FIG. 4(A), drainage holes 19h are formed in the bottom 19b of the folded portion 19. In this example, two drainage holes 19h are provided, and are formed on the corner sides of the bottom 19b of the folded portion 19. The drainage holes 19h are formed so that rainwater that has passed through the drainage channels 15a can pass through. The two drainage holes 19h are formed in positions that vertically face the two outermost convex portions 15 in the horizontal direction when the two exterior wall panels 10 are combined horizontally. The horizontal width of the drainage holes 19h is formed over a range that extends to both horizontal sides of the convex portions 15 that face the drainage holes 19h. This makes it easier for rainwater that flows along both side surfaces of the convex portions 15 to pass through the drainage holes 19h.

[0018] The insertion portion 18 is a portion into which the lateral insertion portion 12 of the adjacent exterior wall panel 10 fits, and is formed as a space between the rear surface of the main body wall portion 11, the inner surface of the folded-back portion 19, and the inner surface of the first U-shaped portion 13a, as shown in Fig. 2(A). When the lateral insertion portion 12 is inserted into the insertion portion 18, the insertion portion 18 supports both vertical ends of the lateral insertion portion 12 so that the lateral insertion portion 12 can slide laterally.

[0019] (Assembly Instructions) Next, a method for assembling the exterior wall panel 10 will be described. As shown in FIG. 3(A), the screw-fastened wall portion 21 of the exterior wall panel 10a is fastened to the vertical furring strip 80 with screws. Then, as shown by arrow Ar1 in Fig. 3(A), by bringing the exterior wall panel 10d closer to the exterior wall panel 10a in the horizontal direction, the lateral insertion portion 12 of the exterior wall panel 10a is inserted into the insertion portion 18 of the exterior wall panel 10d, as shown in Fig. 3(B). Then, the screw-fixed wall portion 21 of the exterior wall panel 10d is screwed to the vertical furring strip 80. In this example, two exterior wall panels 10a, 10d are arranged horizontally, but if three or more exterior wall panels 10 are arranged horizontally, the above-mentioned process of inserting the exterior wall panels 10 horizontally and fastening them with screws is repeated.

[0020] Next, as shown by arrow Ar2 in Figure 3(C), the lower end of the exterior wall panel 10c is brought closer to the upper end of the exterior wall panel 10a, and as shown in Figure 2(A), the lower fitting portion 14 of the exterior wall panel 10c fits into the upper fitting portion 13 of the exterior wall panel 10a. Next, as shown by arrow Ar3 in Fig. 3(C), the lower fitting portion 14 of the exterior wall panel 10e is fitted into the upper fitting portion 13 of the exterior wall panel 10d, and the exterior wall panel 10e is slid toward the exterior wall panel 10c as shown by arrow Ar4 in Fig. 3(C). As a result, the lateral insertion portion 12 of the exterior wall panel 10c is inserted into the insertion portion 18 of the exterior wall panel 10e. In this way, the assembly of the exterior wall panels 10a, 10c, 10d, and 10e is completed. Thereafter, the exterior wall panels 10 are assembled over the entire exterior wall 1 in the same manner.

[0021] The drainage path when rainwater seeps in between the exterior wall panels 10 will be described. As shown by arrow Ar5 in Figure 3(C), if rainwater seeps in between the exterior wall panels 10a and 10d, this rainwater falls downward along the multiple protrusions 15 of the lateral insertion portion 12 of the exterior wall panel 10a and is drained to the outside through the drainage holes 19h. Furthermore, if rainwater seeps into the gap Sp (see Figure 2(B)) between the exterior wall panels 10a and 10c, this rainwater will flow downward from each recess 16 through each recess 17 along the multiple protrusions 15 of the side insertion portion 12, as shown by arrows Ar6 in Figure 3(B), and be drained to the outside through the drainage holes 19h.

[0022] (effect) According to the embodiment described above, the following effects are achieved. (1) The horizontally-attached exterior wall panels 10 are combined vertically and horizontally to form the exterior wall 1, and are long in the horizontal direction. The horizontally-attached exterior wall panel 10 includes a main body wall portion 11 formed in a plate shape along the surface of the exterior wall 1, a lateral insertion portion 12 formed in a plate shape integral with the main body wall portion 11 at one horizontal end side (e.g., the right end side) of the main body wall portion 11, and an insertion receiving portion 18 formed at the other horizontal end side (e.g., the left end side) of the main body wall portion 11 and on the back side of the main body wall portion 11, and configured to allow the insertion of the lateral insertion portion 12 of the horizontally adjacent horizontally-attached exterior wall panel 10 of the exterior wall panel 10. The lateral insertion portion 12 has a convex shape that contacts the back side of the main body wall portion 11 of the horizontally adjacent horizontally-attached exterior wall panel 10 when inserted into the insertion receiving portion 18, and includes a plurality of convex portions 15 positioned away from both ends of the lateral insertion portion 12 in the horizontal direction and extending vertically. According to this configuration, the convex portions 16 guide downward rainwater that seeps in through gaps between laterally adjacent horizontal exterior wall panels 10, thereby preventing rainwater from seeping inside the exterior wall 1. In addition, because the convex portions 16 are formed integrally with the main body wall portion 11 together with the lateral insertion portions 12, no parts such as cover materials are required separately from the exterior wall panels 10. Furthermore, since the convex portion 16 is positioned away from both ends of the lateral insertion portion 12 in the lateral direction, the insertion of the lateral insertion portion 12 into the inserted portion 18 is less likely to be hindered by the convex portion 16, making it possible to smoothly insert the lateral insertion portion 12 into the inserted portion 18.

[0023] (2) The horizontal exterior wall panel 10 includes an upper fitting portion 13 formed at the upper vertical end of the main body wall portion 11, a folded portion 19 formed by folding back from the lower end of the main body wall portion 11 upward on the back side of the main body wall portion 11, and a lower fitting portion 14 connected to the upper end of the folded portion 19 and formed at a position facing the back surface of the main body wall portion 11. The insertion portion 18 is formed between the back surface of the main body wall portion 11, the upper fitting portion 13, and the folded portion 19. The upper fitting portion 13 of the horizontal exterior wall panel 10 is configured to be able to fit into the lower fitting portion 14 of the horizontal exterior wall panel 10 adjacent to the upper side of the horizontal exterior wall panel 10. The lower fitting portion 14 of the horizontal exterior wall panel 10 is configured to be able to fit into the upper fitting portion 13 of the horizontal exterior wall panel 10 adjacent to the lower side of the horizontal exterior wall panel 10. The main body wall portion 11 has a recess 16, which is an example of a plurality of first recesses, formed at the upper end of the surface of the main body wall portion 11, hidden by the adjacent horizontal exterior wall panel 10 on the upper side, and extending in the horizontal direction. The side-side insertion portion 12 has a recess 17, which is an example of a plurality of second recesses, formed on the surface of the side-side insertion portion 12, located above the plurality of protrusions 16, and extending in the horizontal direction on an extension line of the plurality of recesses 16. According to this configuration, the recesses 16 suppress the occurrence of capillary action, in which moisture is sucked up into the gap Sp between two vertically adjacent horizontal exterior wall panels 10. In addition, the recesses 16 allow rainwater that has entered the gap Sp due to wind hitting the exterior wall surface to escape laterally and reach the recesses 17 of the lateral insertion portions 12. This rainwater is guided downward from the recesses 17 by the protrusions 16 due to gravity.

[0024] (3) The horizontal exterior wall panel 10 is integrally formed from metal. The upper fitting portion 13 is located above the multiple recesses 16. The horizontal exterior wall panel 10 is located above and behind the upper fitting portion 13, has a horizontally long plate-like shape, and includes a screw-fastened wall portion 21 that is screwed to a vertical furring strip 80, which is an example of a portion of the horizontal exterior wall panel 10 to be fastened with a screw. According to this configuration, the recess 16 is located below the upper fitting portion 13, so that rainwater is prevented from entering deep into the gap Sp due to wind. Furthermore, since the horizontal exterior wall panel 10 is integrally formed from metal, the structure of the horizontal exterior wall panel 10 can be simplified. In addition, the horizontal exterior wall panel 10 can be stably fixed to the vertical furring strip 80 by the screw-fastened wall portion 21.

[0025] The present invention is not limited to the above-described embodiments and drawings. Modifications (including the omission of components) can be made as appropriate within the scope of the present invention. An example of a modification will be described below.

[0026] (Variation) In the above embodiment, the width of each recess 16 in the vertical direction may be formed to be approximately the same as the arrangement interval between the recesses 16 or larger than this arrangement interval. The number of recesses 16, 17 is not limited to four, but may be one, two, three, five or more. The hole shape of each of the recesses 16, 17 is not limited to a semicircular shape, but may be any shape, such as a triangle or a rectangle. Each protrusion 15 is not limited to a square shape when viewed in the vertical direction, and may be another shape such as a triangle. The number of protrusions 15 is not limited to three, and may be one, two, four or more. The protrusions 15 may be located at the end of the lateral insertion portion 12 in the horizontal direction. The exterior wall panel 10 is not limited to metal siding, but may be ceramic siding. The raised edge portions 12a and 12b may be omitted. The shapes of the upper fitting portion 13 and the lower fitting portion 14 may be changed as appropriate as long as they are fittable. Also, the upper fitting portion 13 and the lower fitting portion 14 may be omitted. The drain hole 19h may be omitted.

[0027] In the above embodiment, as shown in FIG. 1(A), the exterior wall panels 10 are arranged in a single vertical row, but this is not limited thereto, and the exterior wall panels 10 may be arranged in a staggered vertical row as shown in FIG. 1(B). [Explanation of symbols]
