Description

[Technical Field]

[0001] This invention relates to a canopy that forms a right-angle corner with two canopy bodies, and in particular to a canopy that is characterized by a decorative material attached to the underside. [Background technology]

[0002] Patent Document 1 discloses a building eave in which multiple eave plates connected widthwise along the wall surface of a building up to the corner parts are supported by a support frame material fixed to the wall surface, and the corner eave plates are connected widthwise to and supported by corner frame materials protruding diagonally from the corner parts of the building toward the wall surface, and the eave plates along the wall surface and the corner eave plates are connected by butting together widthwise.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-151849 Summary of the Invention [Problem to be solved by the invention]

[0004] In the configuration described in Patent Document 1, long tip members are attached to the tip of the eaves, and when these tip members butt together, a V-shaped protruding or recessed corner is formed at the tip of the corner. Such butted parts may have gaps for adjustment. Also, gaps may occur due to misalignment rather than an intended gap. If such gaps do not fit as intended during construction, inconveniences such as a reduction in design quality or the need for gap adjustment work may occur. Furthermore, such gaps may cause water leaks.

[0005] Therefore, the objective of the present invention is to provide a decorative material that can cover the underside of a corner frame material while improving its design, and that is easy to adjust in size, in a eave that forms a right-angle corner with two eave bodies. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the present invention comprises two eave bodies joined at right angles with their sides butted together diagonally, a corner frame material arranged between the two eave bodies to support the two eave bodies, and a corner end decorative material attached to the tip side of the corner frame material, wherein the corner end decorative material has a V-shaped tip portion arranged so as to substantially overlap below the outside corner shape or inside corner shape formed by the intersection of the two eave bodies. [Effects of the Invention]

[0007] The present invention is as described above and comprises a corner end decorative material attached to the tip side of the corner frame material, the corner end decorative material having a V-shaped tip that is arranged so as to substantially overlap the underside of the outside corner shape or inside corner shape formed by the intersection of two eave main bodies. As a result, the decorative material is arranged up to the tip of the eave main body, and the joint at the tip where the two eave main bodies intersect (the joint further towards the tip of the corner frame material that cannot be covered by the corner frame material) can be covered so that it cannot be seen from below.

[0008] In this specification, the phrase "arranged so as to substantially overlap" refers to a configuration in which the approximately V-shaped surface of the protruding or recessed corner shape and the V-shaped tip of the corner edge decorative material substantially overlap. Therefore, the two do not necessarily need to completely overlap. For example, this also includes a configuration in which the approximately V-shaped surface of the protruding or recessed corner shape and the V-shaped tip of the corner edge decorative material are slightly offset due to drainage slits, clearances, joints, etc., being provided at the tip of the corner edge decorative material. Specifically, in order to form a drainage slit at the tip of the V-shaped tip of the corner edge decorative material, the corner edge decorative material may be intentionally made short so that it does not reach the tip of the protruding or recessed corner shape. Even in this configuration, if the corner edge decorative material can cover the joint where the two eave bodies intersect, further distal to the corner frame material, the design of the underside of the joint can be improved.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] The building eaves 10 according to this embodiment can be placed at a corner 61 where two wall surfaces 60 intersect, and there are eaves for outside corners as shown in Fig. 1 and eaves for inside corners as shown in Fig. 7. Below, we will first explain the eaves for outside corners as an example.

[0011] As shown in Figure 2, the building eaves 10 is composed of an eaves body 11, a wall frame material 20, a wall frame cover 30, a wall frame decorative material 31, a corner frame material 32, a corner frame cover 33, a corner frame decorative material 34, a corner cap 35, a corner end decorative material 36, a corner tip cover 37, a connecting portion 40, and a cross cover 50.

[0012] The eaves main body 11 is a plate-like portion formed by arranging multiple eaves plates 12 side by side. In this embodiment, the multiple eaves plates 12 are connected to each other so that the upper and lower surfaces of the eaves main body 11 are flat. This eaves main body 11 is formed so that it has an equal projection width along the wall surface 60, and at the corner portion 61, two eaves main bodies 11 arranged along the two wall surfaces 60 are joined to each other at a right angle. The side portions where the two eaves main bodies 11 are joined to each other are formed diagonally so that they form a 45-degree angle with the wall surface 60 in a plan view. The side portions of the two eaves main bodies 11 formed diagonally in this way are butted together with a corner frame material 32 sandwiched between them. This allows the two eaves main bodies 11 to be joined so that they are continuous at a right angle.

[0013] The eaves plate 12 according to this embodiment is made of a hollow aluminum material. Although not shown in detail, both sides of the eaves plate 12 are provided with engagement parts that engage with other eaves plates 12, and multiple eaves plates 12 are connected into a single plate by engaging these engagement parts. The eaves plates 12, which are supported only by the wall frame members 20, are formed in elongated rectangular shapes and all have the same length. These eaves plates 12 have both end faces that are parallel to each other.

[0014] On the other hand, the eave plates 12 supported by the corner frame members 32 have their base ends (the ends on the wall surface 60 side) cut out at an angle (approximately 45 degrees) to fit along the corner frame members 32. In other words, because the corner frame members 32 extend at an angle to the wall surface 60, the end faces of the eave plates 12 supported by the corner frame members 32 are cut at an angle to match the angle of the corner frame members 32. The lengths of these eave plates 12 vary depending on the positions at which they are supported by the corner frame members 32.

[0015] These multiple eave plates 12 are lined up along the wall surface 60, with their ends on the wall surface 60 side resting on the wall frame materials 20 and corner frame materials 32. In this way, the ends of the eave body 11 are supported by the wall frame materials 20 and corner frame materials 32. As shown in FIG. 3, these eaves plates 12 are fixed to the wall frame members 20 or the corner frame members 32 by means of mounting bolts 13 and mounting nuts 14 .

[0016] An end frame 17 and an end cover 18 are attached to the end of the eaves body 11. The end frame 17 is a long metal member attached to connect the ends of multiple eaves plates 12 arranged side by side. The end cover 18 is a decorative member attached to the end of the eaves plate 12 so as to cover the end frame 17.

[0017] The wall frame material 20 is a metal member that is fixed to the wall surface 60 to support the eave body 11. The wall frame material 20 according to this embodiment is an aluminum shaped member having a cross-sectional shape as shown in Fig. 3(b). The wall frame material 20 is arranged so as to extend horizontally from a corner portion 61 along the wall surface 60.

[0018] As shown in Figure 3(b), the wall frame material 20 has a flat back surface 20b. The wall frame material 20 is fixed to the wall surface 60 with the back surface 20b in contact with the wall surface 60. In addition, a first protrusion 21, a second protrusion 22, a support piece 23, and a receiving piece 24 are formed to protrude from a side surface 20a, which is the surface opposite the back surface 20b.

[0019] The first protrusion 21 and the second protrusion 22 are protrusions for positioning an upper piece 41b of the wall-side fixing portion 41 of the connecting portion 40, which will be described later. The first protrusion 21 gradually slopes downward toward the tip, and the tip is bent into a substantially J-shape. The second protrusion 22 protrudes below the first protrusion 21 and is smaller than the first protrusion 21. The first protrusion 21 and the second protrusion 22 are set so that the heights of their lower ends are equal to each other.

[0020] The first protrusion 21 may also be used to attach the wall angle member 28. The wall angle member 28 is a member that cooperates with the wall framing member 20 to support the eaves plate 12. Specifically, the eaves plate 12, whose underside is supported by the wall framing member 20, is pressed down from above by the wall angle member 28, thereby sandwiching and supporting the eaves plate 12 from both the top and bottom between the wall framing member 20 and the wall angle member 28. The wall angle member 28 has its upper end hooked inside the first protrusion 21, and its lower end fixed to the eaves plate 12. The wall angle member 28 is attached while avoiding the corner portion 61 and is attached so as not to interfere with (overlap with) the connecting portion 40. In this way, the first protrusion 21 is used as an attachment portion for the wall angle member 28 and also as a positioning portion for the connecting portion 40, allowing the same portion to be shared.

[0021] The support piece 23 is a portion capable of supporting the lower end of a wall-side fixing portion 41 of the connecting portion 40, which will be described later. Because the upper surface of this support piece 23 can support the wall-side fixing portion 41, a storage recess 25 for storing the wall-side fixing portion 41 of the connecting portion 40 is formed between the first protrusion 21, the second protrusion 22, and the support piece 23. The storage recess 25 is formed over the entire longitudinal length of the wall framing material 20 and can hold the wall-side fixing portion 41 of the connecting portion 40 so that it can slide horizontally. Therefore, when fixing the connecting portion 40 to the wall framing material 20, the connecting portion 40 can be positioned by moving it along the storage recess 25. The upper surface of this support piece 23 is inclined downward toward the tip, allowing rainwater and other water that has entered to be discharged toward the tip.

[0022] The receiving piece 24 is a portion for supporting the underside of the eaves plate 12, and has a flat upper surface so that the eaves plate 12 can be placed on it. The base end of the eaves plate 12 placed on the receiving piece 24 can abut against the tip of the support piece 23. By abutting the base end of the eaves plate 12 against the support piece 23, the eaves plate 12 can be positioned in the longitudinal direction.

[0023] The eaves plate 12, which is placed on the receiving piece 24, is fixed using a mounting bolt 13 and a mounting nut 14. That is, first, the mounting bolt 13 is inserted from the top of the eaves plate 12 into a mounting hole (not shown) in the eaves plate 12 and the receiving piece 24. The mounting bolt 13 penetrates the eaves plate 12 and the receiving piece 24 and protrudes downward beyond the receiving piece 24. The eaves plate 12 is fixed to the receiving piece 24 by fastening the mounting nut 14 to the tip of this mounting bolt 13.

[0024] The wall frame cover 30 is a component attached to cover the upper portion of the wall frame material 20. For example, it is an aluminum shaped member having a cross-sectional shape as shown in FIG. 3(b). The wall frame cover 30 has an upper mounting portion 30a provided near the upper end, a lower mounting portion 30b provided near the lower end, and a cover surface 30c that forms an inclined surface connecting the upper mounting portion 30a and the lower mounting portion 30b. The upper mounting portion 30a is fixed near the upper end of the wall frame material 20 with fasteners such as screws. The lower mounting portion 30b abuts against the upper surface of the eaves plate 12. As a result, the wall frame cover 30 covers the upper portion of the joint between the wall frame material 20 and the eaves plate 12.

[0025] The wall frame decorative material 31 is a member attached so as to cover the lower part of the wall frame material 20. For example, it is an aluminum shaped member having a cross-sectional shape as shown in Fig. 3(b). This wall frame decorative material 31 is fixed to the underside of the receiving piece 24 of the wall frame material 20, and covers the tips of the mounting bolts 13 and the mounting nuts 14 so that they cannot be seen from below.

[0026] The corner frame material 32 is a metal member that protrudes from the corner portion 61 diagonally relative to the wall surface 60 and supports the eave main body 11. This corner frame material 32 is arranged between two eave main bodies 11 to support the two eave main bodies 11. The corner frame material 32 in this embodiment is an aluminum shaped member with a cross-sectional shape as shown in Figure 3(a).

[0027] This corner frame material 32 is arranged so that its base end (the end on the wall surface 60 side) faces the corner portion 61, and is fixed to and supported by the wall frame material 20 by connecting portions 40, which will be described later. As shown in Figure 3(a), this corner frame material 32 includes a vertical wall portion 32a, a lateral support portion 32d, a bottom support portion 32e, and a gutter 32f.

[0028] The vertical wall portion 32a is a wall portion extending in the vertical direction, and both side surfaces 32g thereof are flat. Corner-side fixing portions 46 of the connecting portion 40, which will be described later, can be attached to these side surfaces 32g from both sides. In other words, two corner-side fixing portions 46 can be attached so as to sandwich the vertical wall portion 32a. Note that the top portion 32b of this vertical wall portion 32a is not covered with a cover and is exposed to the outside even after assembly, as shown in FIG. 3(a). In addition, a hollow portion 32c extending in the longitudinal direction of the corner frame material 32 is formed directly below this top portion 32b.

[0029] The lateral support portions 32d are portions for supporting the underside of the eaves plate 12, and extend in a direction perpendicular to the vertical wall portion 32a. The upper surface of the lateral support portion 32d is formed flat so that the eaves plate 12 can be placed on it. The lateral support portions 32d are provided on both sides of the vertical wall portion 32a.

[0030] The eaves plate 12, which is placed on the lateral support portion 32d, is fixed using a mounting bolt 13 and a mounting nut 14. That is, first, the mounting bolt 13 is inserted from the top surface of the eaves plate 12 into a mounting hole (not shown) in the eaves plate 12 and the lateral support portion 32d. The mounting bolt 13 penetrates the eaves plate 12 and the lateral support portion 32d and protrudes downward beyond the lateral support portion 32d. The mounting nut 14 is fastened to the tip of this mounting bolt 13, thereby fixing the eaves plate 12 to the lateral support portion 32d.

[0031] The bottom support portion 32e is a portion for supporting the lower surface (lower piece 46c) of the corner-side fixing portion 46 of the connecting portion 40, which will be described later, and extends in a direction perpendicular to the vertical wall portion 32a. By placing the connecting portion 40 on this bottom support portion 32e, the connecting portion 40 can be easily positioned.

[0032] The gutter groove 32f is a groove-shaped groove provided between the lateral support portion 32d and the bottom support portion 32e. The gutter groove 32f is provided over the entire longitudinal length of the corner frame material 32 to drain rainwater that has entered the cover or that has flowed down the eaves plate 12 to the outside.

[0033] The corner frame cover 33 is attached to the top of the corner frame material 32 and is a component that covers the joint between the corner frame material 32 and the eaves plate 12. For example, it is an aluminum shaped member with a cross-sectional shape as shown in FIG. 3(a). This corner frame cover 33 has an upper mounting portion 33a provided near the upper end, a lower mounting portion 33b provided near the lower end, and a cover surface 33c that forms a slope connecting the upper mounting portion 33a and the lower mounting portion 33b. The upper mounting portion 33a is fixed near the upper end of the corner frame material 32 with fasteners such as screws. The lower mounting portion 33b abuts against the upper surface of the eaves plate 12. As a result, the wall frame cover 30 covers the upper part of the joint between the corner frame material 32 and the eaves plate 12.

[0034] In this embodiment, the height of the cover surface 33c of the corner frame cover 33 is set lower than the cover surface 30c of the wall frame cover 30. This is because the corner frame material 32 is lower in height than the wall frame material 20, and therefore the height of the cover material is also lower.

[0035] The corner frame decorative material 34 is a member attached to cover the lower part of the corner frame material 32. For example, it is an aluminum shaped member with a cross-sectional shape as shown in Figure 3(a). This corner frame decorative material 34 is fixed to the underside of the corner frame material 32, and covers the tips of the mounting bolts 13 and the mounting nuts 14 so that they cannot be seen from below.

[0036] The corner flap 35 is a member attached to the tip of the corner frame material 32. By attaching the corner flap 35 to the corner frame material 32, it is possible to close the opening formed between the eaves plate 12 and the tip cover 18 when viewed from above as shown in Figure 1.

[0037] The corner end decorative material 36 is a component attached to the tip of the corner frame decorative material 34. By attaching the corner end decorative material 36 to the corner frame decorative material 34, it is possible to close the opening formed between the eaves plate 12 and the tip cover 18 when viewed from below as shown in Figure 12. In other words, the tip on the upper surface of the eaves plate 12 is covered by the corner flap 35, and the tip on the lower surface is covered by the corner end decorative material 36. This corner end decorative material 36 will be described in detail later. The corner tip cover 37 is a cover that is placed at the position where the two tip covers 18 intersect, and serves to connect the two tip covers 18 at right angles.

[0038] The connecting portion 40 is a member for connecting the side surface 20a of the wall frame material 20 and the side surface 32g of the corner frame material 32. The connecting portion 40 according to this embodiment is a metal fitting having a V-shape in plan view as shown in Fig. 2. As shown in Fig. 3, the connecting portion 40 includes a wall-side fixing portion 41 that abuts against and is fixed to the side surface 20a of the wall frame material 20, and a corner-side fixing portion 46 that abuts against and is fixed to the side surface 32g of the corner frame material 32.

[0039] 3(b), the wall surface side fixing part 41 is formed in an inverted L-shaped cross section and includes a vertical plate-like vertical piece 41a and an upper piece 41b extending at a right angle from the upper end of the vertical piece 41a. This wall surface side fixing part 41 is housed in the housing recess 25 of the wall frame material 20 already described and fixed with bolts.

[0040] 3(a), the corner-side fixing part 46 has a U-shaped cross section and includes a vertical plate-like vertical piece 46a, an upper piece 46b extending at a right angle from the upper end of the vertical piece 46a, and a lower piece 46c extending at a right angle from the lower end of the vertical piece 46a. This corner-side fixing part 46 is placed on the bottom support part 32e of the corner frame material 32 already described, and is fixed with fasteners 47 such as bolts.

[0041] The cross cover 50 is a member disposed at a position connecting the wall frame cover 30 and the corner frame cover 33. The cross cover 50 is a single plate-like member as shown in Fig. 5, and is made of a metal such as aluminum. As shown in Fig. 5, the cross cover 50 includes a cover portion 51.

[0042] The cover portions 51 are portions for covering the wall frame material 20 near the corner portions 61. The intersection cover 50 of this embodiment has two cover portions 51 that are continuous with two wall frame covers 30 that extend in different directions. As shown in FIG. 5(d), each cover portion 51 has substantially the same cross-sectional shape as the wall frame cover 30. As shown in FIG. 5(b), these two cover portions 51 intersect with each other at a right angle in plan view, forming a corner portion 55 at the intersection. The two cover portions 51 are formed symmetrically with respect to each other, with a line passing through the corner portion 55 serving as the center line.

[0043] The cover portion 51 has a cover surface 52 formed as a flat inclined surface. When the cover portion 51 is arranged so as to be continuous with the wall frame cover 30, the surface of the wall frame cover 30 and the cover surface 52 become flush with each other, thereby realizing a unified design.

[0044] A joint portion 54 protrudes from the side of the cover portion 51 facing the end face of the wall frame cover 30. This joint portion 54 has a step with respect to the cover surface 52, and is formed in a position slightly rearward (toward the wall surface 60) from the cover surface 52. Due to the presence of this joint portion 54, when the cross cover 50 is placed so as to be continuous with the wall frame cover 30, as shown in FIG. 4, the joint portion 54 is placed between the cross cover 50 and the wall frame cover 30, forming a gap (joint). The gap formed by this joint portion 54 is filled with a caulking agent or sealant (not shown).

[0045] The cover portion 51 also has an upper edge portion 56 at its upper end portion. As shown in Fig. 5(b), the upper edge portion 56 is formed in an L-shape in plan view so as to fit along the two wall surfaces 60 and the corner portion 61.

[0046] A joint portion 57 is also formed to protrude from the upper edge portion 56. This joint portion 57 has a step with respect to the upper edge portion 56, and is formed slightly below the upper edge portion 56. Due to the presence of this joint portion 57, the joint portion 57 is disposed between the cross cover 50 and the wall surface 60, forming a gap (joint). The gap formed by this joint portion 57 is filled with a caulking agent or a sealant (not shown).

[0047] 4, an opening 53 is formed at the corner 55 where the two cover portions 51 intersect, into which the end of the corner frame cover 33 is inserted. This opening 53 is formed by cutting out the lower part of the cross cover 50 so that it spans the corner 55, and is open on the downward side. This allows the cross cover 50 to be attached from above the corner frame cover 33. For example, after the wall frame cover 30 and the corner frame cover 33 have been attached, the cross cover 50 can be attached by placing it on top of them.

[0048] The opening 53 is sized to completely cover the corner frame material 32 and the two corner frame covers 33 attached to the corner frame material 32. When the end of the corner frame cover 33 is inserted into the opening 53, the end of the corner frame cover 33 becomes invisible in a plan view. Therefore, the cross cover 50 covers the end of the corner frame cover 33 so that it is not exposed, resulting in a good design. The opening 53 also has a step 53a. The step 53a is provided along the edge of the opening 53 and is located slightly rearward (toward the wall surface 60) from the cover surface 52. The step 53a abuts against the upper surface of the corner frame cover 33 inserted into the opening 53. The step 53a is filled with a caulking or sealant (not shown), which improves watertightness.

[0049] In the above description, the cross cover 50 is described as a single member having two cover portions 51. However, as shown in Fig. 6, the cross cover 50 may be formed by combining two cover pieces 58. That is, two cover pieces 58 each form one cover portion 51, and the cross cover 50 may be formed by joining the ends of these two cover pieces 58. As a method for joining the two cover pieces 58, for example, as shown in Fig. 6(b), a joint 58a may be provided where the two cover pieces 58 overlap each other, and the two cover pieces 58 may be joined at a right angle via the joint 58a.

[0050] Furthermore, although the above has been given as an example of eaves for an outside corner, the intersection cover 50 can also be provided in the case of eaves for an inside corner as shown in Figs. 7 and 8, in the same way as in the case of an outside corner.

[0051] The cross cover 50 for an inside corner can have a shape such as that shown in Figures 9 and 10. This cross cover 50 is also a component that is placed at a position that connects the wall frame cover 30 and the corner frame cover 33. The difference between the cross cover 50 for an inside corner and the cross cover 50 for an outside corner is whether the two cover parts 51 form an inside corner or an outside corner. Other basic aspects of the cross cover 50 for an inside corner are the same as those of the cross cover 50 for an outside corner.

[0052] As described above, the underside of the corner frame material 32 according to this embodiment is covered with the corner frame decorative material 34 and the corner end decorative material 36. By using a decorative material divided into at least two components in this way, it is possible to cover the underside of the corner frame material 32 with the exact same dimensions. This point will be explained in detail below.

[0053] First, as shown in Figure 3(a), the corner frame decorative material 34 is attached by engaging with the underside of the corner frame material 32. The corner frame decorative material 34 has a generally U-shaped cross section that opens upward, and is formed with the same cross section along its entire length. The corner frame decorative material 34 has a length approximately equal to that of the corner frame material 32. The tip end surface of the corner frame decorative material 34 in the longitudinal direction is cut straight and is perpendicular to the longitudinal direction of the corner frame decorative material 34. Meanwhile, the base end surface of the corner frame decorative material 34 in the longitudinal direction (the end surface opposite the tip end surface) is formed into a V-shape with the center inward of the V-shape so as to fit along the corner portion 61, as shown in Figure 12.

[0054] As shown in FIG. 3(a), the corner frame decorative material 34 comprises a substantially horizontally disposed lower plate portion 34a, a pair of side plate portions 34b extending upward from both ends of the lower plate portion 34a, and a pair of locking pieces 34c protruding upward from the upper surface of the lower plate portion 34a. Locking claws 34d that engage with the corner frame material 32 are formed near the tips of the pair of locking pieces 34c. The locking claws 34d snap-fit ​​into the corner frame material 32, allowing the corner frame decorative material 34 to be attached to the corner frame material 32. When the corner frame decorative material 34 is attached to the corner frame material 32, the upper surface of the lower plate portion 34a abuts against the lower surface of the corner frame material 32, and the upper ends of the pair of side plate portions 34b abut against the eave body 11. This completely covers the lower surface of the corner frame material 32.

[0055] The base end (the end on the wall surface 60 side) of this corner frame decorative material 34 is formed in a V shape to match the shape of the corner portion 61. A small opening lid that is M-shaped when viewed from the bottom is attached to the small opening of the base end of this corner portion 61.

[0056] However, because the tip of the corner frame decorative material 34 is cut straight, it does not fit perfectly into the V-shaped corner tip of the building eave 10, as shown in Figure 11. This leaves a triangular gap at the tip of the corner frame decorative material 34. This gap is closed by attaching a corner end decorative material 36, as shown in Figure 12.

[0057] 13, the corner end decorative material 36 is a member formed with a tip (the end opposite to the side attached to the corner frame decorative material 34) protruding in a generally V-shape. This corner end decorative material 36 has a lower plate portion 36a arranged to overlap the lower plate portion 34a of the corner frame decorative material 34, and a side plate portion 36b arranged to overlap the side plate portion 34b of the corner frame decorative material 34.

[0058] The lower plate portion 36a is a plate-like portion formed in the shape of a home plate in a plan view. This lower plate portion 36a is formed with approximately the same width as the lower plate portion 34a of the corner frame decorative material 34 so that it can be placed on the underside of the lower plate portion 34a of the corner frame decorative material 34. The tip of this lower plate portion 36a forms a tapered V-shaped tip portion 36c. The side plate portions 36b are a pair of parallel plate-like portions that rise vertically from both ends of the lower plate portion 36a. As shown in FIG. 13, the lower plate portion 36a and the side plate portions 36b form a U-shaped cross section on the inside of the corner end decorative material 36. This U-shaped cross section is formed to follow the U-shape of the surface of the corner frame decorative material 34. This allows the corner end decorative material 36 to be attached by covering the corner frame decorative material 34 from below and to slide within a predetermined range along the longitudinal direction of the corner frame decorative material 34 (the range up to the length of the side plate portions 36b). The lower plate portion 36a has screw holes 36i formed therethrough for attaching the corner end decorative material 36 to the corner frame decorative material 34.

[0059] The V-shaped tip 36c of the lower plate portion 36a has a raised portion 36d along the leading edge of the V-shape. This raised portion 36d rises perpendicularly from the front edge of the lower plate portion 36a. Two raised portions 36d are provided corresponding to the two sides of the V-shaped tip 36c, and the two raised portions 36d are joined at right angles at their tips. The corner end decorative material 36 according to this embodiment is formed by bending a plate material to form the lower plate portion 36a and the side plate portion 36b, and then welding the two raised portions 36d. Specifically, the lower portion of the raised portion 36d is welded to the leading edge of the lower plate portion 36a, the side portion of the raised portion 36d is welded to the front edge of the side plate portion 36b, and the two raised portions 36d are further welded where they butt together. Therefore, the two side plate portions 36b and the two raised portions 36d form a continuous wall. By providing this rising portion 36d, it is possible to close the small edge of the corner frame decorative material 34. Note that in this embodiment, a continuous wall is formed between the two side plate portions 36b and the two rising portions 36d by welding, but this is not limiting as long as a continuous wall can be formed. For example, the wall may be formed by bending, or the wall may be attached using an adhesive or friction stir welding.

[0060] As shown in Figure 12, this corner end decorative material 36 is attached to the corner frame decorative material 34 with screws 36j inserted into screw holes 36i provided in the lower plate portion 36a. At this time, since no holes for the screws 36j are drilled in the corner frame decorative material 34, the screws 36j can be driven into any position. Therefore, the corner end decorative material 36 can be slid along the length of the corner frame decorative material 34 to find the optimal position, and the two can be fixed in that position. At this time, this corner end decorative material 36 is attached so that its base end (the end opposite the V-shaped tip 36c) overlaps the tip end of the corner frame decorative material 34.

[0061] When the corner end decorative material 36 is attached to the corner frame decorative material 34 in this manner, the V-shaped tip portion 36c closes the triangular gap formed at the tip of the corner frame decorative material 34, as shown in Figure 12, thereby achieving a neat design.

[0062] This corner end decorative material 36 can also be used for building eaves 10 of different sizes. That is, as shown in Figure 14, even if the length of the eaves is different, it can be accommodated simply by changing the length of the corner frame decorative material 34. Furthermore, since the tip of the corner frame decorative material 34 can be cut straight, it is easy to adjust the length of the corner frame decorative material 34 at the construction site.

[0063] The corner end decorative material 36 according to this embodiment has a lower plate portion 36a surrounded by a side plate portion 36b and a rising portion 36d, allowing rainwater to be collected inside. A drainage hole 36h is formed at the tip of the substantially V-shaped end of the corner end decorative material 36. The drainage hole 36h is formed by cutting out the tip of the lower plate portion 36a. The provision of this drainage hole 36h allows rainwater that accumulates inside to be drained.

[0064] Because the lower plate portion 36a has screw holes 36i, water leakage may occur through the screw holes 36i rather than through the drain holes 36h. Therefore, watertight material 36k is provided as a water leakage prevention measure. Specifically, as shown in FIG. 13 , tape-like watertight material 36k is attached to the inside of the lower plate portion 36a and the side plate portion 36b. The watertight material 36k is positioned in two locations, one in front of the screw holes 36i and one behind the screw holes 36i, and is sandwiched between the corner frame decorative material 34 and the corner end decorative material 36. This prevents water from flowing around the screw holes 36i and water leakage from the screw holes 36i. In this embodiment, the watertight material 36k is attached with double-sided tape, allowing the watertight material 36k to be pre-positioned on the inner surface of the corner end decorative material 36, improving workability. However, the watertight material 36k is not limited to this tape-like material; sealant, caulking, or other materials may also be used.

[0065] 13(b), the corner end decorative material 36 according to this embodiment has a right-angled notch 36f formed at the tip of the side plate portion 36b, thereby forming a vertical step 36g. The rising portion 36d is set at the same height as the side plate portion 36b on the tip side of the step 36g. In other words, the heights of the side plate portions 36b before and after the notch 36g are different, and the rising portion 36d is formed at the same height as the lower side plate portion 36b. This forms a swallowing portion 36e at the tip of the corner end decorative material 36, with the wall set one step lower. As shown in FIG. 15, the swallowing portion 36e is a portion that protrudes in the distal direction so as to swallow the rear end of the distal end cover 18.

[0066] In the example shown in Figure 15(a), a tip cover 18 equipped with a rain gutter 18a is attached to the tip of the eaves plate 12. This tip cover 18 has a protruding piece 18b that protrudes toward the rear end. The tip of the protruding piece 18b forms a slanted portion 18c that extends diagonally rearward, and the tip of the slanted portion 18c is positioned so that it faces the underside of the eaves plate 12. In this case, the swallowing portion 36e is positioned so that it overlaps the slanted portion 18c when viewed in the vertical direction. This allows the corner end decorative material 36 to cover the underside of the boundary E between the eaves plate 12 and the tip cover 18 (i.e., the rear end position of the tip cover 18). Therefore, water dripping from the boundary E between the eaves plate 12 and the tip cover 18 can be caught by the corner end decorative material 36.

[0067] 15(b) and (c), the tip of the protruding piece 18b of the tip cover 18 forms a vertical portion 18d that extends vertically upward, and the tip of the vertical portion 18d is positioned so that it faces the underside of the eaves plate 12. In this case, the swallowing portion 36e is positioned so that it overlaps the vertical portion 18d when viewed in the up-down direction. This allows the corner end decorative material 36 to cover the underside of the boundary E between the eaves plate 12 and the tip cover 18 (i.e., the rear end position of the tip cover 18). Therefore, water dripping from the boundary E between the eaves plate 12 and the tip cover 18 can be received by the corner end decorative material 36.

[0068] The swallowing portion 36e is not necessarily provided. That is, the corner end decorative material 36 may be formed without the swallowing portion 36e as shown in Fig. 16. In this case, the tip of the corner end decorative material 36 may abut against the rear end of the tip cover 18.

[0069] In the above embodiment, a building eave 10 for an outside corner was described, but in the case of a building eave 10 for an inside corner, a corner end decorative material 36 as shown in Figures 17 and 18 can be used.

[0070] 18, the corner end decorative material 36 for an inside corner is a component formed with a generally V-shaped recess at the end opposite to the side attached to the corner frame decorative material 34. This corner end decorative material 36 comprises a lower plate portion 36a arranged to overlap the lower plate portion 34a of the corner frame decorative material 34, and a side plate portion 36b arranged to overlap the side plate portion 34b of the corner frame decorative material 34.

[0071] The lower plate portion 36a is a plate-like portion formed in a generally arrow-shaped plan view (a concave pentagon formed by deforming one side of a rectangle). The lower plate portion 36a is formed with approximately the same width as the lower plate portion 34a of the corner frame decorative material 34 so that it can be placed on the underside of the lower plate portion 34a of the corner frame decorative material 34. The tip of the lower plate portion 36a forms a V-shaped tip portion 36c, with the center of the V-shaped tip extending inward. The side plate portions 36b are a pair of parallel plate-like portions that rise vertically from both ends of the lower plate portion 36a. The lower plate portion 36a and the side plate portions 36b form a U-shaped cross section on the inside of the corner end decorative material 36, as shown in FIG. 18 . This U-shaped cross section is formed to conform to the U-shape of the surface of the corner frame decorative material 34. This allows the corner end decorative material 36 to be attached by covering it from below over the corner frame decorative material 34, and it can slide within a predetermined range (a range with the maximum length of the side plate portion 36b) along the longitudinal direction of the corner frame decorative material 34. Screw holes 36i for attaching the corner end decorative material 36 to the corner frame decorative material 34 are formed through the lower plate portion 36a.

[0072] The V-shaped tip 36c of the lower plate portion 36a has a raised portion 36d along the leading edge of the V-shape. This raised portion 36d rises perpendicularly from the front edge of the lower plate portion 36a. Two raised portions 36d are provided corresponding to the two sides of the V-shaped tip 36c, and the two raised portions 36d are joined at right angles at their tips. The corner end decorative material 36 according to this embodiment is formed by bending a plate material to form the lower plate portion 36a and the side plate portion 36b, and then welding the two raised portions 36d. Specifically, the lower portion of the raised portion 36d is welded to the leading edge of the lower plate portion 36a, the side portion of the raised portion 36d is welded to the front edge of the side plate portion 36b, and the two raised portions 36d are further welded where they butt together. Therefore, the two side plate portions 36b and the two raised portions 36d form a continuous wall. By providing this rising portion 36d, it is possible to close the small edge of the corner frame decorative material 34. Note that in this embodiment, a continuous wall is formed between the two side plate portions 36b and the two rising portions 36d by welding, but this is not limiting as long as a continuous wall can be formed. For example, the wall may be formed by bending, or the wall may be attached using an adhesive or friction stir welding.

[0073] As shown in Figure 17, this corner end decorative material 36 is attached to the corner frame decorative material 34 with a screw 36j inserted into a screw hole 36i provided in the lower plate portion 36a. At this time, since no hole for the screw 36j is drilled in the corner frame decorative material 34, the screw 36j can be driven into any position. Therefore, the corner end decorative material 36 can be slid along the length of the corner frame decorative material 34 to find the optimal position, and the two can be fixed in that position. At this time, this corner end decorative material 36 is attached so that its base end (the end opposite the V-shaped tip 36c) overlaps the tip end of the corner frame decorative material 34.

[0074] When the corner end decorative material 36 is attached to the corner frame decorative material 34 in this manner, as shown in Figure 17, the V-shaped tip portion 36c fills the concave pentagonal gap formed at the tip of the corner frame decorative material 34, achieving a neat design.

[0075] The corner end decorative material 36 according to this embodiment has a lower plate portion 36a surrounded by side plate portions 36b and rising portions 36d, allowing rainwater to be collected inside. Drainage holes 36h are formed at the tips of the substantially V-shaped ends of the corner end decorative material 36. The drainage holes 36h are formed by cutting out the tips of the lower plate portion 36a (the ends on both sides of the V-shape). Providing these drainage holes 36h allows rainwater that accumulates inside to be drained.

[0076] Because the lower plate portion 36a has screw holes 36i, water leakage may occur through the screw holes 36i rather than through the drain holes 36h. Therefore, watertight materials 36k are provided as a watertight measure. Specifically, as shown in FIG. 18 , tape-like watertight materials 36k are attached to the inside of the lower plate portion 36a and the side plate portion 36b. These watertight materials 36k are positioned in two locations, one in front of the screw holes 36i and one behind them, and are sandwiched between the corner frame decorative material 34 and the corner end decorative material 36. This prevents water from flowing around the screw holes 36i and water leakage from the screw holes 36i. In this embodiment, the watertight materials 36k are attached with double-sided tape, allowing the watertight materials 36k to be pre-positioned on the inner surface of the corner end decorative material 36, improving workability. However, the watertight materials 36k are not limited to tape-like materials; sealants, caulking, etc. may also be used.

[0077] In the above example, the corner edge decorative material 36 is attached to the tip of the corner frame decorative material 34. However, instead, the corner edge decorative material 36 may be attached to the base end of the corner frame decorative material 34 (the end opposite the tip end). In this case, the base end of the corner frame decorative material 34 is cut straight, and a corner edge decorative material 36 that matches the corner shape is attached to this straight base end. Specifically, a corner edge decorative material 36 that is a concave pentagon in plan view, as shown in FIG. 18, can be attached to an eave at an outside corner as shown in FIG. 11. Furthermore, a corner edge decorative material 36 that is a home plate shape in plan view, as shown in FIG. 13, can be attached to an eave at an inside corner as shown in FIG. 17. Note that one longitudinal end face of the corner frame decorative material 34 is cut straight, and the other end face is formed into a V-shape with the center inwardly V-shaped or a tapered V-shape. When attaching this corner frame decorative material 34 to the tip end of an outside corner or the base end of an inside corner, the same corner frame decorative material 34 can be used. Also, when attaching the corner frame decorative material 34 to the base end of an outside corner or the tip end of an inside corner, the same corner frame decorative material 34 can be used. In this way, common components can be used.

[0078] Corner edge decorative materials 36 can also be attached to both ends of the corner frame decorative material 34. In this case, both ends of the corner frame decorative material 34 can be cut straight and corner edge decorative materials 36 can be attached to each of these straight ends. Specifically, for an eave at an exterior corner as shown in FIG. 11, a corner edge decorative material 36 shaped like a home plate in plan view as shown in FIG. 13 can be attached to the tip end, and a corner edge decorative material 36 shaped like a concave pentagon in plan view as shown in FIG. 18 can be attached to the base end. Furthermore, for an eave at an interior corner as shown in FIG. 17, a corner edge decorative material 36 shaped like a home plate in plan view as shown in FIG. 18 can be attached to the tip end, and a corner edge decorative material 36 shaped like a home plate in plan view as shown in FIG. 13 can be attached to the base end. Note that when a corner edge decorative material 36 is attached to the base end of the corner frame decorative material 34, a recessed portion 36e may be provided in the corner edge decorative material 36. The recessed portion 36e may cover the underside of the boundary E between the eave panel 12 and the wall frame decorative material 31. In this way, water droplets dripping from the boundary between the eaves board 12 and the wall frame decorative material 31 can be received by the corner end decorative material 36, preventing water droplets from dripping from the gap and improving the appearance when draining.

[0079] As described above, this embodiment includes a corner frame decorative material 34 attached to the lower part of the corner frame material 32 and a corner edge decorative material 36 attached to the distal end or proximal end of the corner frame decorative material 34. The corner edge decorative material 36 has a generally V-shaped end opposite the end attached to the corner frame decorative material 34. This allows the two decorative materials to cover the underside of the corner frame material 32 and improve its design. Furthermore, because the decorative material attached to the lower part of the corner frame material 32 is divided, the dimensions of the decorative material can be easily adjusted. Specifically, by cutting the end of the corner frame decorative material 34 or fine-tuning the attachment position of the corner edge decorative material 36, the dimensions can be adjusted on-site without complex work such as machining the tip into a generally V-shape.

[0080] Furthermore, the corner end decorative material 36 has a rising portion 36d at the end of the substantially V-shape, and the rising portion 36d covers the small edge of the corner frame decorative material 34. With this configuration, the corner end decorative material 36 functions as a small edge cover, thereby improving the design.

[0081] The corner end decorative material 36 also has drainage holes 36h at the ends of the generally V-shape, which allows water to be drained from a fixed position, making it possible to make the drainage path uniform.

[0082] Furthermore, since the corner frame decorative material 34 and the corner end decorative material 36 are overlapped and fixed with the screws 36j, the length of the decorative material can be easily finely adjusted by simply changing the mounting position of the screws 36j.

[0083] Additionally, watertight materials 36k are disposed between the corner frame decorative material 34 and the corner end decorative material 36, both in front of and behind the positions where the screws 36j are attached. This prevents water from leaking from the screw holes 36i.

[0084] Furthermore, as shown in Figure 15, if the underside of the boundary E between the eaves plate 12 and the tip cover 18 is covered with the corner end decorative material 36, water leakage from the gap can be prevented, thereby making the drainage path uniform when draining.

[0085] (Variation) The corner end decorative material 36 attached to the tip of the corner frame decorative material 34 may be extended to the tip of the building eaves 10, as shown in Figures 19 and 20. In other words, the approximately V-shaped end of the corner end decorative material 36 (V-shaped tip 36c) may be positioned so that it substantially overlaps the underside of the outside corner shape or inside corner shape formed by the intersection of two eaves main bodies 11 (eaves tip V-shaped portion 11a formed on the tip side where the eaves main bodies 11 intersect).

[0086] Below, we will explain modified example 1-3, in which the corner end decorative material 36 is extended to the V-shape at the tip of the building eaves 10 (eaves tip V-shaped portion 11a). Note that these modified examples 1-3 are merely examples, and various modifications are possible within the scope of the claims. For example, embodiments obtained by appropriately combining the technical means disclosed in different embodiments and modified examples are also included in the technical scope of the present invention.

[0087] (Variation 1) Modification 1 will be described with reference to Figures 21 to 23. The basic configuration of this modification is no different from the embodiment already described, so duplicated descriptions will be avoided and only the differences will be described.

[0088] 21 shows a corner end decorative material 36 for an outside corner according to Modification 1. This corner end decorative material 36 comprises a lower plate portion 36a disposed substantially horizontally and side plate portions 36b rising vertically from both side ends of the lower plate portion 36a.

[0089] The lower plate portion 36a is a plate-like portion formed in the shape of a home plate in a plan view. This lower plate portion 36a is arranged parallel to the lower plate portion 34a of the corner frame decorative material 34 and is formed with approximately the same width as the lower plate portion 34a of the corner frame decorative material 34. The tip of this lower plate portion 36a forms a tapered V-shaped tip portion 36c. The side plate portions 36b are a pair of parallel plate-like portions arranged overlapping the side plate portions 34b of the corner frame decorative material 34. As shown in FIG. 21(e), the lower plate portion 36a and the side plate portions 36b form a U-shaped cross section on the inside of the corner end decorative material 36. This U-shaped cross section is formed to follow the U-shape of the surface of the corner frame decorative material 34. This allows the corner end decorative material 36 to be attached by covering it from below over the corner frame decorative material 34, and it can slide within a predetermined range (the range with the maximum length of the side plate portion 36b) along the longitudinal direction of the corner frame decorative material 34. Screw holes 36i for attaching the corner end decorative material 36 to the corner frame decorative material 34 are formed through the side plate portion 36b.

[0090] The V-shaped tip 36c of the lower plate 36a has a raised portion 36d formed along the leading edge of the V-shape. The raised portion 36d rises perpendicularly from the front edge of the lower plate 36a. Two raised portions 36d are provided corresponding to the two sides of the V-shaped tip 36c, and the two raised portions 36d are joined at a right angle at the tip. The upper end of each raised portion 36d is bent inward at a right angle to form an upper piece 36m, as shown in FIG. 21(d). As a result, the lower plate 36a, the raised portion 36d, and the upper piece 36m form a generally U-shaped cross section as shown in FIG. 21(d). This generally U-shaped cross section is intended to cover the leading end of the leading end cover 18, as shown in FIG. 23(b). That is, the raised portion 36d covers the leading end surface (front) of the leading end cover 18, and the upper piece 36m extends to the top surface of the leading end cover 18. A watertight material 36k is attached to the inside (underside) of the upper piece 36m. This watertight material 36k fills the gap between the upper piece 36m and the upper tip of the tip cover 18, preventing water from seeping in through this gap. The presence of the watertight material 36k allows it to come into tight contact with the upper tip of the tip cover 18, which also has the effect of preventing rattling and noise that would be generated by direct contact between the upper piece 36m and the upper tip of the tip cover 18.

[0091] Furthermore, a standing portion 36l is provided at the rear end of the lower plate portion 36a, standing at a substantially right angle from the lower plate portion 36a. The standing portion 36l rises vertically from the rear edge of the lower plate portion 36a. The height of the standing portion 36l is set lower than that of the side plate portion 36b. This standing portion 36l abuts against the underside of the corner frame decorative material 34, as shown in Figure 23(b).

[0092] As shown in FIG. 23 , the corner end decorative material 36 is attached to cover the distal end surface of the distal end cover 18. At this time, the corner frame decorative material 34 and the corner end decorative material 36 are secured together with their side surfaces (side plate portions 34b and 36b) overlapping each other and fastened with screws. Specifically, the corner frame decorative material 34 is attached to the corner frame decorative material 34 with screws inserted into screw holes 36i provided in the side plate portion 36b. At this time, the upper end of the erected portion 36l abuts against the lower surface of the corner frame decorative material 34 (the lower surface of the lower plate portion 34a), forming a step between the lower surface of the corner frame decorative material 34 and the erected portion 36l and lower plate portion 36a of the corner end decorative material 36. This prevents the lower plate portion 34a of the corner frame decorative material 34 from contacting the lower plate portion 36a of the corner end decorative material 36, creating a gap between them. By forming a gap between the corner frame decorative material 34 and the corner end decorative material 36 in this way, water leakage from between them can be reduced. In other words, when the corner frame decorative material 34 and the corner end decorative material 36 are in surface contact, capillary action can cause water to seep into the boundary (tiny gap) between them, which can then leak out. In this regard, forming a step between them can improve drainage, and the standing portion 36l can also block the water.

[0093] 23, this modified example also includes an upper corner end decorative material 38 attached to the upper surface of the tip cover 18. This upper corner end decorative material 38 includes an upper edge portion 38a and a gutter cover portion 38b. The upper edge portion 38a is placed over the rear end portion of the tip cover 18 and is attached to the tip cover 18 with fasteners such as screws. The gutter cover portion 38b is located closer to the tip than the upper edge portion 38a and is attached so as to cover the upper surface of the rain gutter 18a formed on the tip cover 18.

[0094] In this modification, the corner end decorative material 36 and the upper corner end decorative material 38 are attached so as to sandwich the tip cover 18 from above and below. The corner end decorative material 36 and the upper corner end decorative material 38 are attached to the joint where the two tip covers 18 intersect, so these two components can cover the joint. Specifically, the joint where the two tip covers 18 intersect is covered by the corner end decorative material 36 and the upper corner end decorative material 38 so that the tip cover 18 is not exposed when viewed from the bottom, tip surface, or top surface. Therefore, even if there is an adjustment gap at the joint where the two tip covers 18 intersect, this gap can be covered so that it is not exposed.

[0095] The corner end decorative material 36 has a side plate portion 36b, a rising portion 36d, and an upright portion 36l that rise up around the lower plate portion 36a, allowing rainwater to collect inside. A drain hole 36h is formed near the tip of the V-shaped tip portion 36c of the corner end decorative material 36. The provision of this drain hole 36h allows rainwater that collects inside to be drained.

[0096] 21(a), the corner end decorative material 36 has a right-angled notch 36f formed in the side plate portion 36b, which forms a vertical step 36g. As a result, a swallowing portion 36e, which is set one step lower on the tip side, is provided in the side plate portion 36b of the corner end decorative material 36. As shown in FIG. 23, this swallowing portion 36e is disposed opposite the vertical portion 18d at the rear end of the tip cover 18, and is formed to swallow up the rear end of the tip cover 18, as in the embodiment already described.

[0097] While the above has been explained regarding the eaves 10 for buildings with protruding corners, in the case of the eaves 10 for buildings with inside corners, a corner edge decorative material 36 as shown in Figure 22 can be used. The effect of this corner edge decorative material 36 for inside corners is the same as that of the corner edge decorative material 36 for protruding corners, so a detailed explanation will be omitted.

[0098] According to this modification, the approximately V-shaped end (V-tip portion 36c) of the corner end decorative material 36 is positioned to overlap the underside of the outward or inward corner (V-tip portion 11a) formed by the intersection of two eaves main bodies 11, so the decorative material is extended to the tip of the eaves main body 11. This allows the joint where the two eaves main bodies 11 intersect to be covered so that it cannot be seen from below. Therefore, even if there is an adjustment gap between the intersecting eaves main bodies 11, the misalignment or gap can be covered with the corner end decorative material 36, simplifying the adjustment work and improving the design of the finished product. Furthermore, even if water leaks from the misalignment or gap, the corner end decorative material 36 can capture the water.

[0099] Furthermore, the corner end decorative material 36 integrally covers the underside and tip surfaces of the tip covers 18 at the joint where the two tip covers 18 intersect. Therefore, even if the intersecting tip covers 18 are misaligned or if there is a gap for adjustment between the intersecting tip covers 18, the misalignment or gap can be covered with the corner end decorative material 36, simplifying the adjustment work and improving the design of the finished product. Furthermore, even if water leaks from the misalignment or gap, it can be caught by the corner end decorative material 36.

[0100] Furthermore, the corner end decorative material 36 extends to the top surface of the tip covers 18 at the joint where the two tip covers 18 intersect. Therefore, even if the intersecting tip covers 18 are misaligned or if there is an adjustment gap between the intersecting tip covers 18, the misalignment or gap can be covered with the corner end decorative material 36, simplifying the adjustment work and improving the design of the finished product. It also reduces the intrusion of water through the misalignment or gap.

[0101] Additionally, an upper corner end decorative material 38 is provided that is attached to the upper surface of the tip covers 18, and the joint where two tip covers 18 intersect is covered by the corner end decorative material 36 and the upper corner end decorative material 38 so that it is not exposed when viewed from the bottom, tip surface, or top surface of the tip covers 18. As a result, the joint between the intersecting tip covers 18 can be almost completely covered, so even if the intersecting tip covers 18 are misaligned or if there is a gap for adjustment between the intersecting tip covers 18, adjustment work can be simplified and the design of the finished product can be improved. It can also reduce water intrusion from misalignment or gaps.

[0102] In addition, the corner end decorative material 36 can drain water that accumulates inside through drainage holes 36h near the tip. Therefore, rainwater received by the corner end decorative material 36 can be drained from near the tip of the eave 10.

[0103] In addition, because the corner frame decorative material 34 and the corner end decorative material 36 are secured together with screws at their overlapping sides, there is no need for screw holes on the underside. This eliminates the risk of rainwater caught by the corner end decorative material 36 leaking through the screw holes on the underside.

[0104] The corner end decorative material 36 also has a lower plate portion 36a that is disposed substantially horizontally and an upright portion 36l that stands upright at a substantially right angle from the lower plate portion 36a, and the upright portion 36l abuts against the underside of the corner frame decorative material 34, forming a step between the underside of the corner frame decorative material 34, the upright portion 36l, and the lower plate portion 36a. This configuration creates gaps above and below between the corner frame decorative material 34 and the corner end decorative material 36. This reduces the contact surface between them, preventing water leakage due to capillary action.

[0105] (Variation 2) Figures 24 to 26 are diagrams relating to Modification 2. Figure 24 shows a corner end decorative material 36 for an outside corner according to Modification 2, Figure 25 shows a corner end decorative material 36 for an inside corner according to Modification 2, and Figure 26 is a diagram showing an attachment mode of the corner end decorative material 36 according to Modification 2.

[0106] This modified example 2 is basically similar to modified example 1, but differs in at least the following respects. In modified example 1, the rear ends of the protruding pieces 18b of the tip cover 18 are bent vertically upward to form vertical portions 18d, whereas in modified example 2, the rear ends of the protruding pieces 18b are bent diagonally upward to form inclined portions 18c. The corner end decorative material 36 has a swallowing portion 36e that is disposed substantially parallel to and opposite the inclined portions 18c. As shown in Figures 24(a) and 25(a), the corner end decorative material 36 has an oblique notch 36f formed at the tip of the side plate portion 36b, thereby forming an inclined step 36g. The second modification can also achieve the same effects as the first modification.

[0107] (Variation 3) Modification 3 will be described with reference to Figures 27 to 31. The basic configuration of this modification is no different from the embodiment already described, so duplicated descriptions will be avoided and only the differences will be described.

[0108] 27 shows a corner end decorative material 36 for an outside corner according to Modification 3. This corner end decorative material 36 comprises a lower plate portion 36a disposed substantially horizontally and side plate portions 36b rising vertically from both side ends of the lower plate portion 36a.

[0109] The lower plate portion 36a is a plate-like portion formed in the shape of a home plate when viewed from above. This lower plate portion 36a is arranged parallel to the lower plate portion 34a of the corner frame decorative material 34 and is formed with approximately the same width as the lower plate portion 34a of the corner frame decorative material 34. The tip of this lower plate portion 36a forms a tapered V-shaped tip portion 36c. The side plate portions 36b are a pair of parallel plate-like portions arranged overlapping the side plate portions 34b of the corner frame decorative material 34. As shown in FIG. 27(a), the lower plate portion 36a and the side plate portions 36b form a U-shaped cross section on the inside of the corner end decorative material 36. This U-shaped cross section is formed to follow the U-shape of the surface of the corner frame decorative material 34. As a result, the corner end decorative material 36 can be attached by being placed over the corner frame decorative material 34 from below, and can slide within a predetermined range (maximum length of the side plate portion 36b) along the longitudinal direction of the corner frame decorative material 34. Screw holes 36i are formed through the side plate portion 36b for attaching the corner end decorative material 36 to the corner frame decorative material 34. A protrusion engagement portion 36n is provided at the upper tip of the side plate portion 36b for engaging with the protrusion 18e of the tip cover 18. The protrusion 18e in this modified example is formed to protrude downward from the front end of the tip cover 18. The protrusion engagement portion 36n in this modified example is formed by cutting out the upper tip of the side plate portion 36b.

[0110] Furthermore, a standing portion 36l is provided at the rear end of the lower plate portion 36a, standing at a substantially right angle from the lower plate portion 36a. The standing portion 36l rises vertically from the rear edge of the lower plate portion 36a. The height of the standing portion 36l is set lower than that of the side plate portion 36b. This standing portion 36l abuts against the underside of the corner frame decorative material 34, as shown in Figure 31(b).

[0111] As shown in Figure 31, this corner end decorative material 36 is attached so that the tip of the corner end decorative material 36 and the tip of the tip cover 18 are at approximately the same position. At this time, the side surfaces (side plate portions 34b and 36b) of the corner frame decorative material 34 and the corner end decorative material 36 are overlapped and fixed with screws. Specifically, the corner frame decorative material 34 is attached to the corner frame decorative material 34 with screws inserted into screw holes 36i provided in the side plate portion 36b. At this time, the upper end of the erected portion 36l abuts against the underside of the corner frame decorative material 34 (the underside of the lower plate portion 34a), so that a step is formed between the underside of the corner frame decorative material 34 and the erected portion 36l and lower plate portion 36a of the corner end decorative material 36. The effect of this step has been explained above.

[0112] Unlike the first and second modifications, the V-shaped tip 36c of the lower plate 36a in this modification does not have a raised portion 36d. The V-shaped tip 36c is located slightly recessed from the side plate 36b. That is, as shown in FIG. 27(c), when an imaginary V-shaped tip K is imagined to connect the tips of the side plate 36b on both sides, the actual V-shaped tip 36c is located offset inward (in the direction opposite to the protruding direction) from the imaginary V-shaped tip K. This configuration results in a drainage slit 39, as shown in FIG. 31(b), being formed distally of the V-shaped tip 36c when the protrusion 18e of the tip cover 18 and the protrusion engaging portion 36n of the corner end decorative material 36 are attached so that they engage with each other.

[0113] This modified example also includes an upper corner end decorative material 38 as shown in FIG. 28. The upper corner end decorative material 38 is a component attached to the upper surface of the tip cover 18. The upper corner end decorative material 38 includes an upper edge portion 38a, an inclined edge portion 38c, and a vertical edge portion 38d. The upper edge portion 38a is placed over the rear edge of the tip cover 18 and is attached to the tip cover 18 with a fastener such as a screw. The upper edge portion 38a is provided with a screw hole 38e for passing the fastener. The inclined edge portion 38c extends diagonally downward from the front end of the upper edge portion 38a. The vertical edge portion 38d extends vertically downward from the front end of the inclined edge portion 38c. The upper corner end decorative material 38 has a cross-sectional shape as shown in FIG. 28(c) due to these three plate-like portions. The upper corner end decorative material 38 is attached to the joint where two tip covers 18 intersect, and therefore has a pair of upper edge portions 38a, inclined edge portions 38c, and vertical edge portions 38d corresponding to each tip cover 18, and each portion of this pair is connected to each other at right angles.

[0114] In this modification, as shown in Figure 31, a corner end decorative material 36 and an upper corner end decorative material 38 are attached so as to sandwich the tip cover 18 from above and below. The corner end decorative material 36 and the upper corner end decorative material 38 are attached to the joint where two tip covers 18 intersect, so these two components can cover the joint. Specifically, the joint where the two tip covers 18 intersect is covered by the corner end decorative material 36 and the upper corner end decorative material 38 so that the tip cover 18 is not exposed when viewed from the bottom, tip surface, or top surface. Therefore, even if there is an adjustment gap at the joint where the two tip covers 18 intersect, this gap can be covered so that it is not exposed. The corner end decorative material 36 is designed to receive rainwater inside, which can be drained through the drainage slits 39 already described.

[0115] 27(b), the corner end decorative material 36 has a right-angled notch 36f formed in the side plate portion 36b, which forms a vertical step 36g. As a result, a swallowing portion 36e, which is set one step lower on the tip side, is provided in the side plate portion 36b of the corner end decorative material 36. As shown in FIG. 31, this swallowing portion 36e is disposed opposite the vertical portion 18d at the rear end of the tip cover 18, and is formed to swallow up the rear end of the tip cover 18, as in the embodiment already described.

[0116] While the above has been described with respect to the eaves 10 for buildings with protruding corners, in the case of the eaves 10 for buildings with inside corners, it is sufficient to use a corner edge decorative material 36 as shown in Figure 29 and an upper corner edge decorative material 38 as shown in Figure 30. The effects of the corner edge decorative material 36 and upper corner edge decorative material 38 for inside corners are no different from those of the corner edge decorative material 36 and upper corner edge decorative material 38 for protruding corners, so a detailed description will be omitted.

[0117] According to this modification, the approximately V-shaped end (V-tip portion 36c) of the corner end decorative material 36 is positioned to overlap the underside of the outward or inward corner (V-tip portion 11a) formed by the intersection of two eaves main bodies 11, so the decorative material is extended to the tip of the eaves main body 11. This allows the joint where the two eaves main bodies 11 intersect to be covered so that it cannot be seen from below. Therefore, even if there is an adjustment gap between the intersecting eaves main bodies 11, the misalignment or gap can be covered with the corner end decorative material 36, simplifying the adjustment work and improving the design of the finished product. Furthermore, even if water leaks from the misalignment or gap, the corner end decorative material 36 can capture the water.

[0118] Additionally, an upper corner end decorative material 38 is provided that is attached to the upper surface of the tip covers 18, and the joint where two tip covers 18 intersect is covered by the corner end decorative material 36 and the upper corner end decorative material 38 so that it is not exposed when viewed from the bottom, tip surface, or top surface of the tip covers 18. As a result, the joint between the intersecting tip covers 18 can be almost completely covered, so even if the intersecting tip covers 18 are misaligned or if there is a gap for adjustment between the intersecting tip covers 18, adjustment work can be simplified and the design of the finished product can be improved. It can also reduce water intrusion from misalignment or gaps.

[0119] In addition, the corner end decorative material 36 can drain water that accumulates inside through drainage slits 39 near the tip. Therefore, rainwater received by the corner end decorative material 36 can be drained from near the tip of the eave 10 for building.

[0120] In addition, because the corner frame decorative material 34 and the corner end decorative material 36 are secured together with screws at their overlapping sides, there is no need for screw holes on the underside. This eliminates the risk of rainwater caught by the corner end decorative material 36 leaking through the screw holes on the underside.

[0121] The corner end decorative material 36 also has a lower plate portion 36a that is disposed substantially horizontally and an upright portion 36l that stands upright at a substantially right angle from the lower plate portion 36a, and the upright portion 36l abuts against the underside of the corner frame decorative material 34, forming a step between the underside of the corner frame decorative material 34, the upright portion 36l, and the lower plate portion 36a. This configuration creates gaps above and below between the corner frame decorative material 34 and the corner end decorative material 36. This reduces the contact surface between them, preventing water leakage due to capillary action.

[0122] In the above-described embodiment, a corner frame decorative member 34 is attached to the lower part of the corner frame member 32. However, this is not limiting, and as shown in FIG. 32, the corner frame decorative member 34 may not be used. In the example shown in FIG. 32, bolt retaining grooves 32h are formed at both widthwise ends of the lateral support portion 32d. These bolt retaining grooves 32h open upward. The heads of the mounting bolts 13 can be engaged with these bolt retaining grooves 32h to prevent the bolts from rotating. Therefore, the eaves plate 12 can be placed on the bolt retaining grooves 32h, and the mounting bolts 13 protruding upward from the bolt retaining grooves 32h can be inserted into the eaves plate 12. The eaves plate 12 can be fixed to the corner frame member 32 by fastening mounting nuts 14 to the tips of the mounting bolts 13.

[0123] This corner frame material 32 has a substantially horizontal and flat protruding lower surface 32i. A pair of protruding side surfaces 32j continue from both widthwise ends of this protruding lower surface 32i. The protruding side surfaces 32j are vertical surfaces connected at right angles to the protruding lower surface 32i. The eaves plate 12 is placed on the upper end of the protruding side surfaces 32j. With this configuration, a downward protrusion formed by the protruding lower surface 32i and the pair of protruding side surfaces 32j is formed below the eaves main body 11.

[0124] In this configuration, the mounting bolts 13 and mounting nuts 14 are not exposed on the protruding lower surface 32i, so there is no need to cover the lower surface of the corner frame material 32 with the corner frame decorative material 34. Therefore, the corner frame decorative material 34 does not need to be used.

[0125] When the corner frame decorative member 34 is not used, the corner end decorative member 36 may be directly attached to the tip of the corner frame member 32. In this case, the components shown in Figures 23, 26, and 31 as "corner frame decorative member 34, lower plate portion 34a, and side plate portion 34b" can be interpreted as "corner frame member 32, protruding lower surface 32i, and protruding side surface 32j." That is, the side plate portion 36b of the corner end decorative member 36 can be overlapped with the protruding side surface 32j of the corner frame member 32 and secured with screws. Furthermore, by abutting the upright portion 36l against the protruding lower surface 32i of the corner frame member 32, a step is formed between the underside of the corner frame member 32, the upright portion 36l, and the lower plate portion 36a. In this case, although not specifically shown, the shape of the corner end decorative member 36 can be appropriately modified to match the shape of the corner frame member 32.

[0126] As shown in FIG. 33, the corner end decorative material 36 may be attached to the tip of the corner frame material 32 via a bracket 49. In this example, the bracket 49, which has a generally U-shaped cross section, is attached to the underside of the corner frame material 32. The bracket 49 includes a horizontal piece 49a and a pair of vertical pieces 49b. The horizontal piece 49a is formed with approximately the same width as the protruding lower surface 32i and is fixed with screws or the like while abutting against the protruding lower surface 32i. The vertical pieces 49b extend downward from both ends of the horizontal piece 49a in the width direction. The vertical pieces 49b are connected at right angles to the horizontal piece 49a. The surface of the vertical piece 49b is formed to be approximately flush with the protruding side surface 32j. The side panel portion 36b of the corner end decorative material 36 may be overlapped with the vertical piece 49b and fixed with screws.

[0127] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, embodiments obtained by appropriately combining the technical means disclosed in different embodiments and modifications are also included in the technical scope of the present invention.
