[Figure 15] This figure shows a decorative fitting 400 provided in a building component fitting section according to a fourth embodiment of the present invention, and a diagram showing the decorative fitting 400 in the process of being installed. [Modes for carrying out the invention]
[0021] The decorative fittings according to embodiments of the present invention will be described in detail below with reference to the drawings. The decorative fittings according to the present invention will be described as follows: a decorative fitting 100 covering the gaps in the joints (flat sections; the description of these flat sections may be omitted hereafter) of the exterior walls of a building as the first embodiment; a decorative fitting 200 covering the gaps in the inner corners of the exterior walls of a building as the second embodiment; a decorative fitting 300 (including decorative fitting 301 as a modified example) covering the gaps in the outer corners of the exterior walls of a building as the third embodiment; and a decorative fitting 400 covering the gaps in the building parts of the exterior walls of a building as the fourth embodiment. The three decorative fittings 100, 200, and 300 of the first to third embodiments will each have a base material with a watertight material 20 (more specifically, a watertight material... Except for the provision of material 21), decorative fitting 100 corresponds to wall fitting 1 in Patent Document 1, decorative fitting 200 corresponds to exterior wall fitting 1 in Patent Document 2, and decorative fitting 300 corresponds to exterior wall fitting 1 in Patent Document 3, so a detailed explanation may not be repeated here. In addition, building parts in the fourth embodiment include openings such as windows and doors, and overhangs such as eaves and balconies.
[0022] Here, the watertight material 20 (first watertight material 21 provided on the base material 110, etc., and second watertight material 22 provided on the cover material 120, etc.) is a strip with a roughly rectangular cross-section formed from a highly elastic and waterproof material such as ethylene propylene diene rubber foam, polypropylene foam, ethylene propylene rubber foam, foamed urethane resin, or silicone resin, and extends in the longitudinal direction (vertical direction) of the cover material 120 (mechanical properties (compressibility and hardness) will be described later). Furthermore, in the following description, the front side (surface side, outside, outer surface) and the opposite side of this vertical direction, perpendicular to the outer wall of the building, may be described as the back side (back side, inside, inner surface) (see Figures 3, 7, and 11).
[0023] <Features of this invention: The base material also includes a watertight material.> First, the most significant technical feature of this invention, which is that a watertight material is provided not only in the cover material but also in the base material, will be explained below. Here, the decorative fittings 100, 200, and 300 (a modified version of decorative fitting 300, decorative fitting 301, exists, but decorative fitting 300 may be used as a representative example in the explanation) according to the present invention have as their basic function the function of covering the gaps between exterior panels in the joints, inner corners, and outer corners, respectively. For example, as shown in Figures 4(C), 5(C), 6(C) (all for joints), 8(C), 9(C), 10(C) (all for inner corners), and 12(C), 13(C), 14C) (all for outer corners) (from here on, the base material 110 and cover material 120 of the joints may be used as representative examples in the explanation), In the base material 110, Between the edge of the first exterior panel 130A on the base material 110 side and the base material 110, and A watertight material 20 (first watertight material 21) is provided between the edge of the second exterior panel 130B on the base material 110 side and the base material 110, and, In the cover material 120, Between the edge of the cover material 120 on the first exterior panel 130A and the cover material 120, and The second exterior panel 130B is characterized by having a watertight material 20 (second watertight material 22) between the edge of the cover material 120 side and the cover material 120.
[0024] In the case of the base material, this means that not only the base material 110 in the first embodiment, but also the circular area 10 indicated by the dotted line in Figures 3, 7, and 11 of the first to third embodiments is provided with a watertight material 20 (first watertight material 21) in the base material.
[0025] As a result, when the cover material 120 is attached to the base material 110, the watertight material 22 of the cover material 120 is in close contact with the back side of the cover material 120. That is, the watertight material 20 (in this case, the second watertight material 22) is in watertight contact with four surfaces: the first cover portion 120A, the second cover portion 120B, the central cover portion between the first cover portion 120A and the second cover portion 120B, the inner surfaces of the exterior panels 130A and 130B, and the end surface 80 of the exterior panel. Therefore, the effect of preventing rainwater from entering the wall interior through the gap 90 can be further enhanced.
[0026] Furthermore, in addition to the watertight material 20 (here, the second watertight material 22) provided by such cover material 120, the base material 110 according to this embodiment also includes a watertight material 20 (here, the first watertight material 21). The watertight material 21 of the base material is the circular area indicated by the dotted line in Figures 3, 7, and 11. At point 10, it is in close contact with the base material. That is, the watertight material 20 (in this case, the first watertight material 21) As shown in Figures 4(B) and 4(C), the first watertight material 21 is compressed lengthwise by being sandwiched between the first opposing piece 110VA of the base material 110 and the end face of the first exterior panel 130A, and by being sandwiched between the second opposing piece 110VB and the end face of the second exterior panel 130B (sandwiched between the end faces of the exterior panel edges). As shown in Figures 5(B) and 5(C), the first watertight material 21 is sandwiched between the first fixing piece 110HA of the base material 110 and the lower surface of the first exterior panel 130A, and sandwiched between the second fixing piece 110HB and the lower surface of the second exterior panel 130B (sandwiched against the back surface of the edge of the exterior panel) and compressed laterally, As shown in Figures 6(B) and 6(C), the first watertight material 21 is sandwiched between the first corner portion 110CA, from the first fixing piece 110HA to the first opposing piece 110HA of the base material 110, and the end face and back surface of the first exterior panel 130A, and is sandwiched between the second corner portion 110CB, from the second fixing piece 110HB to the second opposing piece 110HB, and the end face and back surface of the second exterior panel 130B, and is compressed into an L-shape.
[0027] Furthermore, the watertight material 20 (first watertight material 21 in this case) of the base material 110 is in watertight contact with 2 to 4 surfaces of the end face 80 of the exterior panel (hereinafter sometimes simply referred to as the end face 80). Therefore, the effect of preventing rainwater from entering the wall interior through the gap 90 can be further enhanced.
[0028] In this way, by positioning the cover material 120 as well as the base material 110 in such a way that the waterproofing properties of the watertight material are maximized, the effect of preventing rainwater from entering the wall interior through the gap 90 can be further enhanced. The shapes of the base material 110 and the cover material 120 are not limited to this embodiment. For example, the central cover portion of the cover material 120 may be formed without any steps between the first cover portion 120A and the second cover portion 120B, and a pattern that is continuous with the surface pattern (such as unevenness or color) of the exterior panel may be applied to the surfaces of the first cover portion 120A, the central cover portion, and the second cover portion 120B.
[0029] <Overall structure> Before describing the detailed structure of these three decorative fittings 100 (for joints), 200 (for inside corners), and 300 (for outside corners), which possess these technical characteristics, we will use decorative fitting 100 as an example and describe the relationship (overall structure) between decorative fitting 100 (base material 110, cover material 120) and the exterior wall base 150, exterior panels 130 (first exterior panel 130A, second exterior panel 130B), etc., below with reference to Figures 1 and 2.
[0030] Figures 1 and 2 are schematic diagrams of the area around the joint (flat surface) of the exterior wall of a building such as a detached house or commercial facility. As shown in Figures 1 and 2, the embodiment of the present invention includes a decorative fitting 100, an exterior wall base 150, and an exterior panel 130 (first exterior panel 130A, second exterior panel 130B).
[0031] The exterior wall base 150 is typically made up of columns or furring strips, but in this embodiment, it is a furring strip fixed to a column (not shown) of the exterior wall or an existing exterior wall, and is arranged along the outer surface (front surface) of the column. In this embodiment, the surface of the exterior wall base 150 opposite to the surface on which the column is located (back surface) is considered the outer surface of the exterior wall base 150, and the base material 110 is fixed to this outer surface with fixing nails N or the like. The fixing method is not limited to fixing nails N, and the exterior wall base 150 may also be fixed with tapping screws or staples, or by other general fixing methods.
[0032] The exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are metal sidings formed integrally by having a surface made of a metal plate such as an aluminum-zinc alloy plated steel sheet or a stainless steel sheet, with a foamed insulation material such as polyisocyanurate foam or polyurethane attached to the back surface, and further covering the foamed insulation material from the back side with aluminum foil or the like, and are formed in a substantially flat shape that is long in one direction. In this embodiment, the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are typically set to a length of up to about 8000 mm.
[0033] Although not shown in the diagram, the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are supported and fixed in multiples arranged horizontally on the outer surface of the exterior wall base 150, with their longitudinal direction aligned with the horizontal direction. In other words, the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are installed horizontally on the exterior wall base 150.
[0034] Furthermore, the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) may be made of ceramic siding made of cement or fibrous materials, resin siding made of resin or fibrous materials, wood siding, etc. In other words, the decorative fittings 100, 200, and 300 of the present invention are not limited to exterior walls in which the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are made of metal siding. Also, the decorative fittings 100, 200, and 300 of the present invention are not limited to exterior walls in which the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are installed horizontally.
[0035] Most of the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) have a wavy, mountain-shaped, stepped, or other uneven pattern formed on their outer surface. When the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) of this embodiment have an uneven pattern, the depth of the pattern is formed to be approximately 0.2 mm to 7.0 mm.
[0036] The exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are arranged on the outer surface of the exterior wall base 150 with their end faces 80 (end face 80A of the first exterior panel 130A, end face 80B of the second exterior panel 130B) butted against each other. As shown in Figures 1 and 2, the exterior panels 130 (first exterior panel 130A, second exterior panel 130B) are arranged side by side on either side of a reference line (shown as a dashed line in Figures 3, 7, and 11) that passes through the center between the left and right sides of the exterior wall base 150, and a predetermined gap 90 is defined between their abutting end faces 80. The decorative fittings 100 are installed along the gap 90 between the abutting end faces 80 of the exterior panels 130 (first exterior panel 130A, second exterior panel 130B).
[0037] Thus, in the first embodiment (the second and third embodiments), the exterior includes a pair of exterior panels 130 (first exterior panel 130A, second exterior panel 130B) arranged adjacent to each other in a planar manner from left to right (or perpendicularly in order to form an inner corner or outer corner in the second and third embodiments), an exterior wall base 150 that supports each of these exterior panels 130 (first exterior panel 130A, second exterior panel 130B), and decorative fittings 100 (decorative fittings 200 in the second embodiment, decorative fittings 300 in the third embodiment) that are attached along the gap 90 between the abutting end faces (panel end faces) 80 of the exterior panels 130 (first exterior panel 130A, second exterior panel 130B).
[0038] As shown in Figures 1 and 2, the decorative trim piece 100 (here, the decorative trim piece 100 according to the first embodiment is used as a representative example to explain the overall structure first; therefore, in the second embodiment it will be the decorative trim piece 200, and in the third embodiment it will be the decorative trim piece 300) is an exterior member installed in the joint of the exterior wall (in the second embodiment it will be the inside corner, and in the third embodiment it will be the outside corner), and comprises a base material 110 and a cover material 120. Material 110 is a thin metal plate that is long in one direction and formed into an irregular cross-section by bending or other processes. It is fixed to the outer surface of the outer wall base 150 in a vertical orientation, with its longitudinal direction matching the extending direction (up and down direction) of the outer wall base 150. In this embodiment, the longitudinal dimension of the base material 110 is usually set to approximately 450 mm to 8000 mm. Multiple base materials 110 are installed in a vertical arrangement according to the length of the outer wall base 150. Alternatively, one base material 110 may be cut in the shorter direction to match the length of the outer wall base 150. Regardless of whether the base material 110 is cut in the shorter direction or not, the cover material 120 is installed by inserting the lower end 120D of another cover material 120 one level above it into its upper end 120U, as shown in Figures 1 and 2, so that the upper end 120U is on the surface side (the upper end 120U is on the back side).
[0039] The base material 110 is preferably formed from a metal sheet. The metal sheet can be made from materials such as iron, aluminum, copper, stainless steel, titanium, or aluminum-zinc alloy plated steel. Furthermore, the base material 110 may be formed not only by bending, but also by roll forming, press forming, extrusion forming, notching, etc. Additionally, the base material 110 may be formed from a synthetic resin material such as polyvinyl chloride resin or polycarbonate resin.
[0040] The base material 110 is formed in a symmetrical shape with respect to the aforementioned reference line. The base material 110 also has a first base portion 110A, a second base portion 110B, and an engagement groove 110C.

It comprises a base material 310 fixed to the exterior wall base 350 and a cover material 320 that engages with the base material 310 and covers the gap 90 between the exterior panels.
[0080] The base material 310 includes a first fixing piece 310A fixed to the first mounting surface 350SA (the outer surface (front surface) of the outer wall base 350) of the outer wall base 350 facing the first exterior panel 330A, a second fixing piece 310B fixed to the second mounting surface 350SB (the outer surface (front surface) of the outer wall base 350) of the outer wall base 350 facing the second exterior panel 330B, and an engagement groove 310C located between the first fixing piece 310A and the second fixing piece 310B, which is provided to protrude toward the cover material 320 side from the first fixing piece 310A and the second fixing piece 310B, and which engages with and holds the cover material 320.
[0081] Furthermore, the cover material 320 includes a first cover portion 320A positioned along the outer surface (front surface) of the first exterior panel 330A, a second cover portion 320B positioned along the outer surface (front surface) of the second exterior panel 330B, and a base material 310 between the first cover portion 320A and the second cover portion 320B. It has an engaging piece 320C that is provided to protrude to the side and is inserted into and engaged with an engaging groove 310C.
[0082] The engagement groove 310C of the base material 310 has an opening 310C1 into which the leg portion 320C1 can be inserted, and an engagement projection 310C2 that protrudes along the inner edge of the opening 310C1 and engages with and holds the claw portion 320C2.
[0083] The engaging piece 320C of the cover material 320 has a leg portion 320C1 that extends in a direction perpendicular to the length direction of the cover along the inner surface of the central cover portion between the first cover portion 320A and the second cover portion 320B and is formed to protrude toward the base material 310, and a claw portion 320C2 provided at the tip of the leg portion 320C1 and engaging with the engaging groove 310C of the base material 310.
[0084] Here, we will explain the differences between the base material 310 that constitutes the decorative fitting 300 shown in Figure 11(A) and the base material 311 that constitutes the decorative fitting 301 shown in Figure 11(B).
[0085] First, the base material 310 is connected to the engagement groove 310C on the first exterior panel 330A side via a first fixing piece 310HA facing the back surface of the edge of the first exterior panel 330A and a first vertical connecting piece 310VA that is bent in a direction parallel to the front-to-back direction at the first bending portion 310CA. On the second exterior panel 330B side, the base material 310 is connected to the engagement groove 310C via a first fixing piece 310HB facing the back surface of the edge of the second exterior panel 330B and a second vertical connecting piece 310VB that is bent in a direction parallel to the front-to-back direction at the second bending portion 310CB.
[0086] On the other hand, on the first exterior panel 330A side, the base material 311 has a first fixing piece 310HA facing the back surface of the edge of the first exterior panel 330A and a first opposing piece 311VA facing the end face of the edge of the first exterior panel 330A connected at approximately a right angle by a first bent portion 310CA, and further connected to the engagement groove 311C via a first connecting piece 311VHA that is bent at approximately a right angle. On the second exterior panel 330B side, the first fixing piece 310HB facing the back surface of the edge of the second exterior panel 330B and a first opposing piece 311VB facing the end face of the edge of the second exterior panel 330B connected at approximately a right angle by a second bent portion 310CB, and further connected to the engagement groove 311C via a second connecting piece 311VHB that is bent at approximately a right angle.
[0087] In Figure 11(B), a portion of the base material 310 is shown as a dotted line on the base material 311. While the base material 311 has two sets of approximately orthogonal pieces—a first fixing piece 310HA and a second fixing piece 310HB facing the back surface of the edge of the exterior panel, and a first opposing piece 311VA and a second opposing piece 311VB facing the end face of the edge of the exterior panel—the base material 310 only has a first fixing piece 310HA and a second fixing piece 310HB facing the back surface of the edge of the exterior panel. Therefore, the base material 310 cannot hold the watertight material between the end faces of the edge of the exterior panel. This is because the first vertical connecting piece 310VA and the second vertical connecting piece 310VB do not face (are not parallel to) the end face of the edge of the exterior panel.
[0088] A key feature of these decorative fittings 300 and 301 is that when the engaging piece 320C of the cover material 320 is inserted into the engaging groove 310C of the base material 310 or base material 311, the cover material 320 is engaged with and held (fixed) to the base material 310 or base material 311 (as shown in Figures 12(C), 13(C), and 14(C)), it has the following configuration.
[0089] In this embodiment, as in the first embodiment, the watertight material 20 (first watertight material 21) in the base material is provided in the circular area 10 shown by the dotted line in Figures 3, 11, and 11. Also, the watertight material 20 (second watertight material 22) provided in the cover material is the same as in the first embodiment, so the explanation will not be repeated here.
[0090] Furthermore, as shown in Figures 11(B) and 12(A) to 12(C), the base material 311 has a first opposing piece 311VA that faces the end face of the edge of the first exterior panel 330A, and a second opposing piece 311VB that faces the end face of the edge of the second exterior panel 330B, and is characterized by having a first watertight material 21 between the first opposing piece 311VA (and the end face of the edge of the first exterior panel 330A) and between the second opposing piece 311VB (and the end face of the edge of the second exterior panel 330B).
[0091] In this case, as shown in transitional order (in chronological order) from Figure 12(A) to Figure 12(C), the first watertight material 21 is provided between the first opposing piece 310VA of the base material 311 and the end face of the edge of the first exterior panel 330A, and between the first opposing piece 310VB and the end face of the edge of the second exterior panel 330B, as shown in Figure 12(A) (for example, the first watertight material 21 is provided by bonding it to the first opposing piece 310VA and the second opposing piece 310VB). Then, as shown by the white arrows in Figure 12(A), the first exterior panel 330A is moved to be close to the first opposing piece 310VA, and the second exterior panel 330B is moved to be close to the second opposing piece 310VB, and fixed to the exterior wall base 350. As shown by the black arrows in Figure 12(B), the cover material 320 is attached to the base material 311, and as shown in Figure 12(C), the first watertight material 21 is sandwiched between the end face of the first opposing piece 310VA and the edge of the first exterior panel 330A, and between the end face of the second opposing piece 310VB and the edge of the second exterior panel 330B.
[0092] Furthermore, as shown in Figures 11(A) and 13(A) to 13(C), the base material 310 has a first fixing piece 310HA facing the back surface of the edge of the first exterior panel 330A and a second fixing piece 310HB facing the back surface of the edge of the second exterior panel 330B, and is characterized by having a first watertight material 21 between the first fixing piece 310HA (and the back surface of the edge of the first exterior panel 330A) and between the second fixing piece 310HB (and the back surface of the edge of the second exterior panel 330B).
[0093] In this case, as shown in transitional order (time progression) from Figure 13(A) to Figure 13(C), the first watertight material 21 is provided between the first fixing piece 310HA of the base material 310 (or base material 311) and the back surface of the edge of the first exterior panel 330A, and between the second fixing piece 310HB and the back surface of the edge of the second exterior panel 330B, as shown in Figure 13(A) (for example, the first watertight material 21 is provided by bonding it to the first fixing piece 310HA and the second fixing piece 310HB). Then, as shown by the white arrows in Figure 13(A), the first exterior panel 330A is moved to be close to the first fixing piece 310HA, and the second exterior panel 330B is moved to be close to the second fixing piece 310HB, and fixed to the exterior wall base 350. As shown by the black arrows in Figure 13(B), the cover material 320 is attached to the base material 310 (or base material 311), and as shown in Figure 13(C), the first watertight material 21 is sandwiched between the back surface (bottom surface) of the edge of the first fixing piece 310HA and the first exterior panel 330A, and between the back surface (bottom surface) of the edge of the second exterior panel 330B, respectively.
[0094] In this case, the same effects can be achieved by using the base material 311 shown in Figure 11(B). This is because the base material 311 also has the first fixing piece 310HA and the second fixing piece 310HB that the base material 310 has (as shown in Figure 13(D)).
[0095] Furthermore, as shown in Figures 11(B) and 14(A) to 14(C), the base material 311 has a first opposing piece 311VA that faces the end face of the edge of the first exterior panel 330A, and a second opposing piece 311VB that faces the end face of the edge of the second exterior panel 330B, and the first exterior panel The first watertight material 21 is provided, with a first fixing piece 310HA facing the back surface of the edge of panel 330A and a second fixing piece 310HB facing the back surface of the edge of the second exterior panel 330B, and a first watertight material 21 provided from the first opposing piece 311VA through the first corner 310CA to the first fixing piece 310HA (between the first exterior panel 330A and the edge of the first exterior panel 330A), and from the second opposing piece 311VB through the second corner 310CB to the second fixing piece 310HB (between the second exterior panel 330B and the edge of the second exterior panel 330B). In this case, as shown in Figure 14(C), the watertight material 21 is formed in an L shape.
[0096] In this case, as shown in transitional order (time progression) from Figure 14(A) to Figure 14(C), the first watertight material 21 is provided in the base material 311 between the first opposing piece 311VA to the first fixing piece 310HA and the end face and back surface of the edge of the first exterior panel 330A, and between the second opposing piece 311VB to the second fixing piece 310HB and the end face and back surface of the edge of the second exterior panel 330B, as shown in Figure 14(A) (for example, the first watertight material 21 is provided by bonding it to the first opposing piece 311VA and the first fixing piece 310HA, and the second opposing piece 310VB and the second fixing piece 310HB). Then, as shown by the white arrows in Figure 14(A), the first exterior panel 330A is moved so as to approach the first opposing piece 311VA and the first fixing piece 310HA from an oblique angle, and the second exterior panel 330B is moved so as to approach the second opposing piece 311VB and the second fixing piece 310HB from an oblique angle, and fixed to the exterior wall base 350. As shown by the black arrows in Figure 14(B), the cover material 320 is attached to the base material 311, and as shown in Figure 14(C), an L-shaped first watertight material 21 is sandwiched between the first opposing piece 311VA and the first fixing piece 310HA and the edge of the first exterior panel 330A, and between the second opposing piece 311VB and the second fixing piece 310HB and the edge of the second exterior panel 330B.
[0097] <Fourth embodiment (building component fitting section)> Referring to Figure 15, a decorative fitting 400 according to a fourth embodiment of the present invention will be described. Figures 15(A) to (C) show the temporal transitions in the construction process, Figure 15(D) shows the cover material 420 constituting the decorative fitting 400, Figure 15(E) shows the base material 410 constituting the decorative fitting 400, Figure 15(F) shows the engagement state between the base material 410 and the cover material 420, and Figure 15(G) shows an enlarged view of the engagement state. Furthermore, the method of fixing the exterior wall base 450 (vertical furring strips in this case), the base material 410 and the first exterior panel 430A is not limited to the screws and nails shown. This decorative fitting 400 covers the gap 90 between the building parts of the exterior wall (first exterior panel 430A, eaves ceiling 460). More specifically, as shown in Figure 15(B), the end face 80A of the first exterior panel 430A and the surface 460S of the eaves ceiling 460 are arranged in a state where they abut each other perpendicularly, and the gap 90 between the building component fittings that exists between these abutted surfaces is covered.
[0098] As shown in Figures 15(A) to (G), the decorative fitting 400 is composed of a base material 410 attached to the exterior wall base 450 and a cover material 420 which is engaged with and fixed to the base material 410 by having an engaged portion 420C that engages with the engaging portion 410C of the base material 410.
[0099] As shown in Figures 15(A) to (C) and (E), the base material 410 has a first fixing piece 410A that is fixed to the first mounting surface 450SA (the outer surface (front surface) of the outer wall base 450) of the outer wall base 450 facing the first exterior panel 430A, and an engaging portion 410C which is the end of the first fixing piece 410A and is provided to protrude from the first fixing piece 410A toward the cover material 420, and engages with and holds the cover material 420.
[0100] Furthermore, as shown in Figures 15(A)~(C) and (D), the cover material 420 has a first cover portion 420A which is arranged along the outer surface (front surface) of the first exterior panel 430A, and a first cover portion 420A The bar portion 420A has an engaged portion 420C which is the end of the bar portion 420A and is provided to protrude from the first cover portion 420A toward the base material 410, and which engages with the engaging portion 410C.
[0101] The engaging portion 410C of the base material 410 includes an engaging piece 410C1 that can be inserted into the engaged portion 420C, and a folded engaging piece 410C2 formed by folding the tip of the engaging piece 410C1 multiple times, which engages with and holds the folded engaged piece 420C2.
[0102] The engaged portion 420C of the cover material 420 includes an insertion guide piece 420C1 that extends from the end of the first cover portion 420A in a direction perpendicular to the length of the cover and is formed to protrude toward the base material 410, and a folded engaged portion 420C2 that is formed by folding the tip of the insertion guide piece 420C1 multiple times and engages with the engaged portion 410C of the base material 410.
[0103] A key feature of this decorative fitting 400 is that when the engaging portion 410C of the base material 410 is inserted into the engaged portion 420C of the cover material 420, the cover material 420 is engaged with and held (fixed) to the base material 410 (as shown in Figure 15(C)), it has the following configuration.
[0104] As shown in Figure 15(C), In the base material 410, A watertight material 20 (first watertight material 21) is provided between the edge of the first exterior panel 430A on the base material 410 side and the base material 410. In the cover material 420, The present invention is characterized by providing a watertight material 20 (second watertight material 22) between the edge of the first exterior panel 430A on the cover material 420 side and the cover material 420.
[0105] Furthermore, as shown in Figures 15(A) to 15(D), the base material 410 has a first fixing piece 410HA facing the back surface of the edge of the first exterior panel 430A, and is characterized by having a first watertight material 21 between the first fixing piece 410HA (and the back surface of the edge of the first exterior panel 430A).
[0106] In this case, as shown in transitional order (time progression) from Figure 15(A) to Figure 15(C), the first watertight material 21 is provided between the first fixing piece 410HA of the base material 410 and the back surface of the edge of the first exterior panel 430A, as shown in Figure 15(A) (for example, in the state shown in Figure 15(A), the first watertight material 21 is bonded to the first fixing piece 410HA). Then, as shown by the white arrow in Figure 15(A), the first exterior panel 430A is moved to be close to the first fixing piece 410HA and fixed to the exterior wall base 450. As shown by the black arrow in Figure 15(B), the cover material 420 is attached to the base material 410. As shown in Figure 15(C), the first watertight material 21 is sandwiched between the first fixing piece 410HA and the back surface (right side) of the edge of the first exterior panel 430A, and the second watertight material 22 is sandwiched between the first cover part 420A and the surface surface (left side) of the edge of the first exterior panel 430A.
[0107] As shown in Figure 15(G), the engagement state between the engaging portion 410C of the base material 410 and the engaged portion 420C of the cover material 420 can be described in more detail as follows: the tip of the folded engaging piece 410C2 is hemmed once, and the tip of the folded engaged piece 420C2 is hemmed twice, and the increased thickness of the tips allows them to catch on each other, thus maintaining the engagement state.
[0108] In addition, in any embodiment, the first watertight material may be bonded to the base material in advance, or it may be bonded at the construction site. Similarly, the second watertight material may be bonded to the covers material in advance, or it may be bonded at the construction site.
[0109] As described above, this embodiment is a further development in view of the prior art, and by appropriately providing watertight material not only in the cover material but also in the base material, it is possible to provide a decorative fitting that can be placed over the gaps of exterior wall panels, which further enhances the effect of preventing rainwater from entering.
[0110] <Mechanical properties of watertight materials (compression ratio and hardness)> The watertight material 20 used in the decorative fittings described above (first watertight material 21 provided on the base material 110, etc., and second watertight material 22 provided on the cover material 120, etc.) is a strip with a roughly rectangular cross-section formed from highly elastic and waterproof materials such as ethylene propylene diene rubber foam, polypropylene foam, ethylene propylene rubber foam, foamed urethane resin, and silicone resin. The mechanical properties (compressibility and hardness) of this watertight material will be explained in detail below.
[0111] The mechanical properties of this watertight material are characterized by the fact that the compressive load after 10 seconds of compressing a 10cm x 10cm test piece at a speed of 10mm / min to a predetermined compression ratio is defined as the compressive hardness, and the compressive hardness differs between the first watertight material 21 and the second watertight material 22. In this way, by making the compressive hardness of the first watertight material 21 attached to the base material different from that of the second watertight material 22 attached to the cover material, it is possible to provide a decorative fitting that covers the gaps of exterior wall panels, which can be fitted and fixed to the base material, and the base material, which is firmly fixed to the base of the exterior wall with fixing nails N, etc., because the mounting strength of the cover material itself and the mounting strength of the base material itself differ. By selecting the compressive hardness of the watertight material in accordance with the mounting strength, it is possible to provide a decorative fitting that covers the gaps of exterior wall panels, which can further exhibit the effect of preventing rainwater intrusion by appropriately providing watertight material not only on the cover material but also on the base material.
[0112] Preferably, the compressive hardness of the first watertight material 21 is greater than the compressive hardness of the second watertight material 22. The first watertight material 21, which is provided on a base material that is firmly fixed to the base of the exterior wall with fixing nails N, etc., may have a greater compressive hardness (harder) than the second watertight material 22. In other words, even if a watertight material with high compressive hardness is attached to a base material that is firmly fixed, the base material is firmly fixed to the base of the exterior wall with fixing nails N, etc., so it is unlikely that construction defects will occur due to the hardness of the first watertight material 21.
[0113] More preferably, the compressive hardness of the first watertight material 21 is 0.5 to 10 N / cm² at 50% compression. 2 Furthermore, the compressive hardness of the second watertight material 22 is 0.1 to 1.0 N / cm² when compressed to 50%.2 Therefore, by employing a watertight material with such compression hardness, and by appropriately providing watertight material not only in the cover material but also in the base material, it is possible to provide a decorative fitting that can be placed over the gaps of exterior wall panels, which further enhances the effect of preventing rainwater intrusion.
[0114] It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is indicated by the claims rather than by the foregoing description, and all modifications within the meaning and scope equivalent to the claims are intended to be included. [Industrial applicability]
[0115] The present invention is preferable for decorative fittings for exterior walls installed in joints, inner corners, and outer corners of the exterior walls of buildings, and is particularly preferable in that it can further enhance the effect of preventing rainwater intrusion.
