[Technical Field]

[0001] The present invention relates to a flashing accessory, a flashing material, and a flashing unit that can be attached to the end of a building's flashing material. [Background technology]

[0002] Conventionally, end caps (accessories) that fit into the openings at the ends of flashing materials to cover them have been known. Meanwhile, Patent Document 1 discloses a flashing material for flood prevention that contains a water-expansion material and can prevent water from entering under the floor in the event of a flood. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2023-167052 Summary of the Invention [Problem to be solved by the invention]

[0004] When end caps are used with the flashing material described in Patent Document 1, the end caps are simply fitted into the openings at the ends of the flashing material. This makes it easy for gaps to form between the end caps and the openings, making it difficult to adequately prevent water from seeping in. As a result, even water, such as normal rain, can easily seep in through the gaps and cause the water-expanding material to expand, leading to other problems.

[0005] Therefore, the object of the present invention is to provide accessories for a draining material, a draining material, and a draining unit that can prevent water from entering the interior of the draining material through the opening at the end of the draining material. [Means for solving the problem]

[0006] In a first aspect, the accessory for a water-repellent material of the present invention is an accessory for a water-repellent material that is attached to the end of the water-repellent material while covering the opening at the end to prevent water from entering the interior of the water-repellent material through the opening at the end, and can be fastened to the end of the water-repellent material with a screw (bolt).

[0007] In a second aspect, the accessory for a water-repellent material of the present invention is an accessory for a water-repellent material that is attached to the end of the water-repellent material while covering the opening at the end to prevent water from entering the interior of the water-repellent material through the opening at the end, and comprises an accessory main body and a water-stopping material, and the accessory main body is configured to be able to be screwed to the end of the water-repellent material via the water-stopping material.

[0008] In a third aspect, the accessory for a water-draining material of the present invention is an accessory for a water-draining material that is attached to the end of the water-draining material while covering the opening at the end to prevent water from entering the interior of the water-draining material through the opening at the end, and comprises an accessory main body and a water-stopping material, the water-stopping material being attached to the opposing surface of the accessory main body that faces the opening when the accessory main body is attached to the end of the water-draining material, and the accessory main body having a hole for inserting a screw when attaching it to the end of the water-draining material.

[0009] The term "accessories for water-repellent materials" as used herein is a concept that broadly encompasses accessories that are applied to the ends of water-repellent materials, such as end caps, joints, external corners, internal corners, and the like.

[0010] The water-repellent material of the present invention is a water-repellent material having an attachment portion that is attached to the building main body, an extension portion that extends downward and forward from the attachment portion, a front curtain portion that extends downward from the front of the extension portion, and a storage portion that is located below the extension portion and behind the front curtain portion and is capable of storing a water-expansion material, and has screw holes for screwing a water-repellent accessory that covers the opening at the end of the water-repellent material to the end.

[0014] A draining unit 1 according to one embodiment of the present invention will be described below with reference to Figures 1 to 9. Figure 1 shows a draining unit 1 according to one embodiment of the present invention attached to a base, which is part of a building skeleton. The building skeleton 100 in this embodiment has a foundation 101, a foundation packing 102, a base 103, and the like that support a building (not shown).

[0015] Foundation 101 rises from the ground and extends longitudinally in direction A, perpendicular to the plane of the paper in FIG. 1 . Decorative mortar (not shown) is formed on the outdoor side of foundation 101. Foundation packing 102 is formed longitudinally along direction A and is installed on foundation 101. Foundation packing 102 is also formed with a plurality of ventilation holes 102a for connecting the outdoor side with the indoor side. The plurality of ventilation holes 102a are formed spaced apart from one another along direction A. Base 103 is also formed longitudinally along direction A and is installed on foundation packing 102. A drainage unit 1 is attached to outdoor side 103a of base 103 to prevent the infiltration of rainwater and the like.

[0016] As shown in Figure 2, the draining unit 1 in this embodiment has a draining material 10 and end caps 50 (draining accessories) attached to each end of the draining material 10 in direction A. Although Figure 2 only shows the end cap 50 attached to the right end of the draining material 10, an end cap 50 is also attached to the left end of the draining material 10. The draining unit 1 will be described below with its outdoor side as the front and its indoor side as the rear. Furthermore, direction A is a horizontal direction that is perpendicular to the front-to-back direction B, and will therefore be referred to as the left-to-right direction A in the following description. The left-to-right direction A is the direction when viewed from the front.

[0017] As shown in FIG. 1, the flashing unit 1 is attached to a base 103 with the support portion 19 and horizontal flange portion 54 (both described below) positioned on a foundation 101 via water-expansion materials 41, 64. Typically, multiple flashing units 1, each closed at both ends with end caps 50, are lined up along the left-right direction A. By installing in this manner, water infiltration through the connecting portions can be reduced, improving waterproofing performance. Alternatively, multiple flashing members 10 may be lined up in the left-right direction A, and an end cap 50 may be attached to the outer end of the flashing member 10 positioned outermost among the multiple flashing members 10 in the left-right direction A.

[0018] 3 and 4, the flashing material 10 in this embodiment has an attachment portion 11, an extension portion 12, a front flap portion 13, a storage portion 14, a water-swelling material 30, and two fixing members 90. The attachment portion 11, the extension portion 12, the front flap portion 13, the storage portion 14, and the water-swelling material 30 are all formed to be elongated in the left-right direction A. Furthermore, the attachment portion 11, the extension portion 12, the front flap portion 13, and the storage portion 14 that make up the flashing material 10 are made of metal such as aluminum, but may also be made of other materials such as synthetic resin.

[0019] The mounting portion 11 is a plate-like portion formed in a vertical plane along the up-down direction C. The mounting portion 11 is attached to the base 103 with a nail or the like, with its upper end aligned with a line drawn on the side surface 103a of the base 103. The extension portion 12 is a plate-like portion that extends obliquely downward (front-downward) from the lower portion of the mounting portion 11. This allows rainwater that falls onto the extension portion 12 from an exterior wall material (not shown) formed on the side surface 103a of the base 103 to be guided toward the front hanging portion 13 side.

[0020] As shown in Fig. 4, the front hanging portion 13 is a plate-like portion extending vertically downward from the front end of the extension portion 12. In this embodiment, the flashing material 10 has a main body portion 2, a detachable portion 3 that is detachable from the main body portion 2, and a support member 4. As shown in Fig. 5(a), the main body portion 2 has an attachment portion 11, an extension portion 12, the front hanging portion 13, a lower plate portion 21, an upper rear wall 16a, a lower rear wall 16b, a connecting portion 18, a support portion 19, a water-swelling material 41, a water-stopping material 42, etc. As shown in Fig. 5(b), the detachable portion 3 has an upper front wall 15a, a lower front wall 15b, a bottom wall 17, a water-swelling material 30, a water-stopping material 43, and two fixing members 90, etc.

[0021] As shown in Fig. 4, the storage section 14 is provided below the extension section 12 and behind the front hanging section 13. The storage section 14 has an upper front wall 15a, a lower rear wall 16b, a bottom wall 17, a rear lower plate section 21b serving as an upper wall, and a storage space S surrounded by these walls 15a, 16b, 17, and 21b. These walls 15a, 16b, 17, and 21b are formed to extend over the entire length of the water-repellent material 10 in the left-right direction A.

[0022] As shown in FIG. 5(a), the lower plate 21 of the main body 2 is disposed below the extension 12 and extends horizontally rearward from the front hanging portion 13. The lower plate 21 has a front lower plate 21a connected to the front hanging portion 13 and the connecting portion 18, and a rear lower plate 21b connected to the connecting portion 18 and the upper rear wall 16a. The connecting portion 18 is a plate-like portion formed in a vertical plane along the up-down direction C and extends the entire length of the flashing material 10 along the left-right direction A. The rear lower plate 21b forms the upper wall of the storage space S. The front lower plate 21a has a through-hole 21c that penetrates in the up-down direction C. The through-hole 21c extends the entire length of the flashing material 10 along the left-right direction A. A screw 74 (described later) of the support member 4 is passed through the through-hole 21c.

[0023] Two screw fastening portions 21d, 21e are formed on the upper surface of the rear lower plate portion 21b. The screw fastening portion 21d is located at a corner where the rear lower plate portion 21b and the connecting portion 18 are connected. The screw fastening portion 21e is located rearward of the screw fastening portion 21d. These screw fastening portions 21d, 21e are located apart from each other in the front-rear direction B. Each screw fastening portion 21d, 21e is formed by removing a portion of the arc portion of a hollow tube extending the entire length of the flashing material 10 in the left-right direction A, and has a generally C-shaped cross section. The screw fastening portions 21d, 21e have screw holes 21d1, 21e1 on the inner circumferential surface of the hollow tube. In other words, the screw holes 21d1, 21e1 are formed the entire length of the flashing material 10 in the left-right direction A. The screw fastening portions 21d, 21e are configured so that when a screw 81 (described later) is screwed into these screw holes 21d1, 21e1, the inner surfaces of the screw holes 21d1, 21e1 engage with the threaded portion of the screw 81, thereby fastening the screw 81.

[0024] Furthermore, eight downwardly protruding projections 21f are formed on the underside of the rear lower plate 21b. These projections 21f extend over the entire length of the water stripping material 10 in the left-right direction A. The upper rear wall 16a of the main body 2 is a plate-like portion that extends vertically upward from the rear end of the lower plate 21. The upper rear wall 16a connects the rear end of the extension portion 12 and the rear end of the lower plate 21.

[0025] As shown in Figures 4 and 5(b), the upper front wall 15a of the storage section 14 is part of the detachable section 3 and is formed in a vertical plane along the up-down direction C. The upper front wall 15a is a plate-like section that extends vertically upward from the upper surface of the bottom wall 17. The upper end of the upper front wall 15a is arranged spaced apart from the rear lower plate section 21b in the up-down direction C. This forms a ventilation section 14a at the front upper part of the storage section 14. The ventilation section 14a extends along the left-right direction A over the entire length of the water-repellent material 10.

[0026] As shown in FIG. 4, the lower rear wall 16b of the storage section 14 is disposed rearward of the upper front wall 15a and is formed in a vertical plane along the up-down direction C. The lower rear wall 16b is part of the main body 2 and is a plate-like portion extending vertically downward from the rear portion of the rear-lower plate portion 21b. The lower rear wall 16b is formed with a plurality of ventilation holes 16c penetrating in the thickness direction (front-rear direction). The plurality of ventilation holes 16c are arranged side by side along the left-right direction A. In this embodiment, a plurality of ventilation holes 16c are formed, but only one ventilation hole 16c may be formed as long as the desired opening area can be ensured.

[0027] As shown in FIGS. 4 and 5(a), the support portion 19 is a part of the main body 2 and is a plate-like portion extending horizontally in the front-to-rear direction B from the lower end of the lower rear wall 16b. The support portion 19 also extends along the entire length of the flashing material 10 in the left-to-right direction A. The support portion 19 is positioned to protrude rearward beyond the lower rear wall 16b. When the flashing material 10 is attached to the base 103, the rear end of the support portion 19 abuts against the foundation gasket 102, forming a space between the lower rear wall 16b and the foundation gasket 102. This space prevents the air vent 16c in the lower rear wall 16b from being blocked by areas other than the air vent 102a in the foundation gasket 102, and prevents the air vent 102a from being blocked by areas other than the air vent 16c in the lower rear wall 16b. This prevents a decrease in ventilation of the building skeleton 100.

[0028] A downwardly protruding protrusion 19a is formed on the underside of the front portion of the support part 19. The protrusion 19a is located slightly rearward from the front end of the support part 19. The protrusion 19a is also formed to extend over the entire length of the water-repellent material 10 in the left-right direction A.

[0029] The water-expanding material 41 is formed in a sheet shape and is attached to the entire underside of the portion of the support portion 19 rearward of the protrusion 19a. The water-expanding material 41 is made of the same material as the water-expanding material 30 described below. The water-stopping material 42 is also formed in a sheet shape and is attached to the rear surface of the upper rear wall 16a. The water-expanding material 41 may be made of a material other than the water-expanding material 30 (e.g., rubber, flexible resin, etc.) as long as it is capable of preventing water from entering between the support portion 19 and the foundation 101. The water-stopping material 42 may be made of the same material as the water-expanding material 30 or a different material (e.g., rubber, flexible resin, etc.) as long as it is capable of preventing water from entering between the mounting portion 11 and the base 103.

[0030] As shown in Figures 4 and 5(b), the bottom wall 17 of the storage section 14 is part of the detachable section 3 and has a bottom plate section 17a and an attachment plate section 17b. The bottom plate section 17a is a plate-like section that extends horizontally in the front-to-rear direction B and extends further forward than the upper front wall 15a. The attachment plate section 17b is a plate-like section that extends rearward from above the rear end section of the bottom plate section 17a. A waterproof material 43 is attached to the entire underside of the attachment plate section 17b. The waterproof material 43 is made of the same material as the waterproof material 42.

[0031] A fitting portion 17c that can fit into the front end of the support portion 19 is formed on the underside of the bottom wall 17. The fitting portion 17c is also formed to extend along the left-right direction A over the entire length of the water-repellent material 10.

[0032] 4 and 5(b), the lower front wall 15b is part of the detachable portion 3 and is formed in a vertical plane along the up-down direction C. The lower front wall 15b is disposed slightly rearward of the upper front wall 15a. The lower front wall 15b is a plate-like portion that extends vertically downward from the lower surface of the bottom wall 17.

[0033] As shown in Figure 4, the water-swelling material 30 is accommodated in the accommodation space S of the accommodation unit 14. More specifically, the water-swelling material 30 is disposed on the bottom wall 17 over the entire length of the accommodation unit 14 in the left-right direction A. The water-swelling material 30 may be disposed anywhere in the accommodation space S, but is preferably disposed in a position that does not block the ventilation portion 14a and is separated from the lower rear wall 16b. This makes it possible to prevent the water-swelling material 30 from blocking the ventilation portion 14a and the ventilation holes 16c when it has not absorbed water.

[0034] The water-swelling material 30 is a member made of a known material that expands in volume by absorbing water. In this embodiment, the water-swelling material 30 is made of highly water- and moisture-absorbent fibers made by fiberizing a polymer whose main component is sodium polyacrylate, but it may also be made of other materials.

[0035] The water-expandable material 30 has a band shape that extends along the entire length of the flashing material 10 in the left-right direction A. When the water-expandable material 30 has not absorbed water, an air passage that connects the ventilation portion 14a and the ventilation hole 16c is secured between the water-expandable material 30 and the rear lower plate portion 21b in the storage space S, as shown by the solid line in FIG. 4. On the other hand, if water enters the storage space S through the ventilation portion 14a due to underfloor flooding or the like, the water-expandable material 30 absorbs water. When the water-expandable material 30 has absorbed water, it expands to fill the entire storage space S, as shown by the two-dot chain line in FIG. 4. As a result, the expanded water-expandable material 30 blocks the air passage in the storage space S. This blocks communication between the ventilation portion 14a and the ventilation hole 16c. Furthermore, by forming multiple protrusions 21f on the underside of rear lower plate 21b, as shown in Fig. 4, multiple protrusions 21f bite into the upper part of expanded water-expanding material 30. This effectively prevents water from entering between the underside of rear lower plate 21b and water-expanding material 30.

[0036] The two fixing members 90 are arranged at both ends of the flashing material 10 in the left-right direction A. While FIG. 3 shows one fixing member 90 attached to the right end of the flashing material 10, a fixing member 90 is also attached to the left end of the flashing material 10. The two fixing members 90 fix both ends of the water-expanding material 30 housed in the housing portion 14 in the left-right direction A to the bottom wall 17. Each fixing member 90 has a fixing portion 91 and a screw 92.

[0037] As shown in Figures 3 and 4, the fixing portion 91 includes an upper horizontal plate portion 91a, a lower horizontal plate portion 91b, and a vertical plate portion 91c connecting the horizontal portions 91a and 91b, and has a U-shape. The upper horizontal plate portion 91a has a longer length in the left-right direction A and a longer length in the front-rear direction B than the lower horizontal plate portion 91b. In other words, the upper horizontal plate portion 91a has a larger planar area than the lower horizontal plate portion 91b. The length of the upper horizontal plate portion 91a in the front-rear direction B is approximately the same as the length of the water-expanding material 30 in the front-rear direction B before expansion. The lower horizontal plate portion 91b and the vertical plate portion 91c have the same length in the front-rear direction B. The vertical plate portion 91c is positioned outside the upper horizontal plate portion 91a and the lower horizontal plate portion 91b in the left-right direction A. As shown in Figure 4, the lower horizontal plate portion 91b has a hole 91d penetrating in the up-down direction C. An internal thread corresponding to the external thread of the screw 92 is formed on the inner peripheral surface of the hole 91d.

[0038] When fixing the water-expanding material 30 with the fixing member 90, first, the upper horizontal plate portion 91a of the fixing part 91 is positioned so that a portion of the end of the water-expanding material 30 in the left-right direction A is sandwiched between the fixing member 90 and the bottom wall 17. Then, the screw 92 is inserted into the hole 91d and tightened until the tip of the screw 92 abuts the underside of the bottom wall 17. In this state, by further tightening the screw 92 a predetermined amount, the fixing member 91 moves downward, and the upper horizontal plate portion 91a approaches the bottom wall 17. In this way, the end of the water-expanding material 30 in the left-right direction A is sandwiched and fixed between the bottom wall 17 and the upper horizontal plate portion 91a. This clamping and fixing by the fixing member 90 is performed on both ends of the water-expanding material 30 in the left-right direction A. In this way, the water-expanding material 30 is fixed to the storage section 14.

[0039] The support members 4 are members for supporting the detachable portion 3 on the main body 2 and are arranged at a predetermined pitch in the left-right direction A of the flashing material 10. For example, in the case of a 3-m-long flashing material 10, the support members 4 are attached at intervals of 600 to 700 mm. As shown in FIG. 4 , the support members 4 include a first member 71, a second member 72, a third member 73, and two screws 74 and 75. The first member 71 is a flat plate arranged between the extension portion 12 and the front lower plate 21a. The length of the first member 71 in the front-to-rear direction B is longer than the width of the through-hole 21c in the front-to-rear direction B and shorter than the distance between the front hanging portion 13 and the connecting portion 18. Therefore, both ends of the first member 71 in the front-to-rear direction B are supported by the front lower plate 21a. A hole 71a is formed in the first member 71 at a position facing the through-hole 21c in the up-down direction C. An internal thread corresponding to the external thread of the screw 74 is formed on the inner peripheral surface of the hole 71a.

[0040] The second member 72 includes a horizontal plate portion 72a, an inclined plate portion 72b, and a vertical plate portion 72c connecting the plate portions 72a and 72b, and has a generally inverted U-shape. The horizontal plate portion 72a has a hole 72a1 through which a screw 74 can be inserted. The inclined plate portion 72b has a hole 72b1. The inner surface of the hole 72b1 has a female thread corresponding to the male thread of the screw 75. The first member 71 and the second member 72 are connected by aligning the hole 71a and the hole 72a1 so that the hole 71a faces the hole 72a1 and fastening the screw 74 inserted into the hole 72a1 into the hole 71a. Furthermore, loosening the screw 74 increases the separation distance between the first member 71 and the second member 72 in the vertical direction C. This allows the support member 4 to be moved in the left-right direction A, enabling the flashing material 10 to be moved to an appropriate position.

[0041] The third member 73 includes an oblique plate portion 73a, a horizontal plate portion 73b, and an oblique plate portion 73c connecting these plate portions 73a and 73b, and has a generally Z-shape. The oblique plate portion 73a has a hole 73a1 through which a screw 75 can be inserted. The second member 72 and the third member 73 are connected by aligning the hole 72b1 and the hole 73a1 so that the hole 72b1 faces the hole 73a1, and then fastening the screw 75 inserted into the hole 73a1 into the hole 72b1.

[0042] Here, the operation of attaching and detaching the detachable part 3 to and from the main body part 2 will be described. When removing the detachable part 3 from the main body part 2, first remove the screw 75 shown in FIG. 4 to remove the third member 73 from the second member 72. Then, move the detachable part 3 forward to remove the front end of the support part 19 from the fitting part 17c. Thereafter, move the detachable part 3 diagonally downward and forward to remove it from the main body part 2.

[0043] By configuring the detachable part 3 to be detachable from the main body 2 in this way, it is possible to replace the water-swelling material 30 stored in the storage part 14. At this time, the entire detachable part 3 may be replaced with a new one, or the two fixing members 90 may be removed from the detachable part 3 to remove the water-swelling material 30, and then the new water-swelling material 30 may be fixed to the detachable part 3 to replace only the water-swelling material 30.

[0044] When attaching the detachable part 3 to the main body 2, the procedure is reversed from the removal procedure described above. More specifically, the fitting part 17c of the detachable part 3, to which the water-expanding material 30 is fixed by the two fixing members 90, is fitted into the front end of the support part 19 of the main body 2. Then, while the front part of the bottom wall 17 is supported from below by the horizontal plate part 73b of the third member 73, it is fixed to the third member 73 and the second member 72 with the screws 75. This completes the attachment and detachment operation of the detachable part 3 to the main body 2.

[0045] When the detachable part 3 is attached to the main body 2, the front end of the bottom wall 17 is positioned downward and away from the lower end of the front hanging part 13. In other words, the water-repellent material 10 has a ventilation part 20 between the lower end of the front hanging part 13 and the front end of the bottom wall 17, as shown in Figures 3 and 4. This allows air from outside to flow through the ventilation part 20 to the ventilation part 14a.

[0046] As shown in Figures 6 and 7, the end cap 50 in this embodiment has an end cap main body 51 (accessory main body), two water-stopping materials 62 and 63, and a water-expansion material 64. The end cap main body 51 is manufactured by folding and assembling an aluminum plate. The end cap main body 51 may also be made of a steel plate such as a stainless steel plate, a Galtite (registered trademark) steel plate, or a Galvalume (registered trademark) steel plate, or a synthetic resin.

[0047] The end cap body 51 also has a sealing portion 52, a vertical flange portion 53, and a horizontal flange portion 54. As shown in FIG. 2, the sealing portion 52 is a vertical plate portion that covers and seals the opening 10a at the end of the water-repellent 10 in the left-right direction A, and extends along the front-to-back direction B and the up-down direction C. As shown in FIGS. 3 and 4, the opening 10a is an area defined by the extension portion 12, the front flap portion 13, the upper rear wall 16a, the lower rear wall 16b, and the bottom wall 17. The sealing portion 52 is formed in a rectangular shape that resembles the outline of the opening 10a. It is sufficient for the sealing portion 52 to be able to seal the opening 10a at the end of the storage section 14 in the left-right direction A.

[0048] 8 and 9, the sealing portion 52 is formed with two holes 52a penetrating in the left-right direction A. The two holes 52a are positioned opposite the two screw fastening portions 21d, 21e in the left-right direction A when the end cap 50 covers the end portion of the flashing material 10 in the left-right direction A. The two holes 52a are holes for inserting screws 81 when attaching the end cap 50 to the end portion of the flashing material 10 in the left-right direction A.

[0049] The vertical flange portion 53 is a flat plate extending in the left-right direction A and the up-down direction C, and is formed long in the up-down direction C. A hole 53a is formed in the vertical flange portion 53, penetrating in the front-to-back direction B. The hole 53a is located in the center of the vertical flange portion 53 in the up-down direction C, and a screw or nail is passed through the hole 53a when fixing the drainer unit 1 to the base 103. The horizontal flange portion 54 is a flat plate extending in the left-right direction A and the up-to-down direction B, and is formed in a substantially square shape. The vertical flange portion 53 and the horizontal flange portion 54 are bent and positioned so as to be located on one side of the sealing portion 52 in the left-to-right direction A.

[0050] The water-stopping materials 62 and 63 are both made of the same material as the above-described water-stopping materials 42 and 43 and are formed in a sheet shape. The water-expanding material 64 is also made of the same material as the above-described water-expanding material 41 and is also formed in a sheet shape. Note that the water-stopping material 62 may be made of the same material as the above-described water-expanding material 30, or may be made of a material such as rubber or a soft resin, as long as it is capable of preventing water from entering through the opening 10a when the end cap 50 is attached to the flashing material 10, and the water-stopping material 63 may be made of the same material as the above-described water-expanding material 30, as long as it is capable of preventing water from entering through the connecting portion of the flashing material 10.

[0051] As shown in FIGS. 6 and 7, the water-stopping material 62 is attached to the entire opposing surface 52b (see FIG. 9) of the sealing portion 52 that faces the flashing material 10. In other words, the water-stopping material 62 is attached to the opposing surface 52b that faces the opening 10a of the end cap body 51 when the end cap body 51 is attached to the end of the flashing material 10. The water-stopping material 62 is arranged on the opposite side of the sealing portion 52 from the vertical flange portion 53 and the horizontal flange portion 54. The water-stopping material 62 has the same planar shape and size as the sealing portion 52. Two holes 62a are formed in the water-stopping material 62, penetrating in the left-right direction A. The two holes 62a are arranged in positions opposite the two holes 52a in the left-right direction A. The water-stopping material 62 is formed to be thicker than the vertical plate portion 91c of the fixing portion 91. As a result, when the end cap 50 is attached to the water-repellent material 10, the waterproofing material 62 can absorb the thickness of the vertical plate portion 91c and come into contact with the opening 10a.

[0052] The water stopping material 63 is attached to the entire rear surface of the vertical flange portion 53. The water stopping material 63 has a similar planar shape to the vertical flange portion 53, and is formed so that its length in the left-right direction A and the up-down direction C is slightly longer than that of the vertical flange portion 53. The water stopping material 63 has a hole 63a formed therethrough in the front-rear direction B. The hole 63a is positioned opposite the hole 53a in the front-rear direction B.

[0053] The water-expandable material 64 is attached to the entire underside of the horizontal flange portion 54. The water-expandable material 64 has a similar planar shape to the horizontal flange portion 54, and although its length in the front-to-rear direction B is the same, its length in the left-to-right direction A is slightly longer than that of the horizontal flange portion 54. Note that the water-expandable material 64 may be made of a material such as rubber or a soft resin, as long as it is capable of preventing water from entering between the end cap 50 and the foundation 101.

[0054] When attaching the end cap 50 to the end of the flashing material 10 in the left-right direction A, as shown in FIG. 2, first, the opening 10a at the end of the flashing material 10 in the left-right direction A is covered with the sealing portion 52 via the water-stopping material 62. Then, screws 81 are inserted into the holes 52a, 62a and screwed into the screw holes 21d1, 21e1 of the screw-retaining portions 21d, 21e. This causes the threaded portions of the two screws 81 to engage with the screw holes 21d1, 21e1, and the end cap body 51 is screwed to the end of the flashing material 10 with the water-stopping material 62 positioned between the end of the flashing material 10 and the end cap body 51. At this time, the water-stopping material 62 is pressed against the end of the flashing material 10 when the end cap 50 is attached, preventing water from entering the interior of the flashing material 10 through the opening 10a at the end of the flashing material 10. In this manner, the flashing unit 1 is constructed.

[0055] Next, a method for attaching the flashing unit 1 to the building skeleton 100 will be described below. The flashing unit 1 containing the water-expansive material 30 before absorbing water is prepared. Then, as shown in FIG. 1 , the mounting portion 11 of the flashing unit 1 is attached to the side surface 103a of the base 103 of the building skeleton 100 with nails or the like. At this time, the flashing unit 1 is attached to the base 103 with the upper end of the mounting portion 11 aligned with the lines drawn on the side surface 103a of the base 103. At this time, the flashing unit 1 is attached to the base 103 with the water-stopping material 42 pressed against the side surface 103a of the base 103. At this time, the flashing unit 1 is attached to the base 103 with the support portion 19 and horizontal flange portion 54 abutting against the foundation 101 via the water-expansive materials 41, 64. Thereafter, a screw (not shown) is screwed into the side surface 103a of the base 103 through the hole 63a of the end cap 50, and the end cap 50 itself is attached to the base 103 with the waterproofing material 63 pressed against the side surface 103a of the base 103. In this way, the drip-water unit 1 is attached to the building skeleton 100.

[0056] As described above, with the end cap 50 of the flashing material 10 in this embodiment, the water-stopping material 62 can be placed between the end of the flashing material 10 and the end cap body 51, and the end cap body 51 can be screwed to the end of the flashing material 10. In this case, the end cap 50 can be attached by pressing the water-stopping material 62 against the end of the flashing material 10, which prevents water from entering the interior of the flashing material 10 through the opening 10a at the end of the flashing material 10.

[0057] As a modified example, the two holes 52a do not have to be formed in the sealing portion 52 of the end cap body 51. In other words, it is sufficient that at least one hole 52a is formed.

[0058] As a modified example, the two holes 52a may not be formed in the sealing portion 52 of the end cap body 51. In this case, the end cap 50 may be attached to the end of the flashing material 10 by passing a screw 81 through a portion of the sealing portion 52 facing the screw fastening portions 21d, 21e and threading the screw 81 into the screw holes 21d1, 21e1. In other words, the material and thickness of the end cap body 51 may be adjusted appropriately so that the screw 81 can be passed through and fastened.

[0059] The formation of the hole 52a in the end cap body 51 makes it easier to screw the screw 81 into the screw holes 21d1, 21e1, and makes it easier to attach the end cap 50 to the flashing material 10.

[0060] According to the flashing material 10 of this embodiment, the screw holes 21d1 and 21e1 allow the end cap 50 to be screwed to the end of the flashing material 10. At this time, the end cap 50 can be attached by pressing it against the end of the flashing material 10, which prevents water from entering the interior of the flashing material 10 through the opening 10a at the end of the flashing material 10.

[0061] As a variant, the water-stopping material 62 need not be provided between the end cap 50 and the flashing material 10. Even in this case, the end cap 50 can be screwed to the end of the flashing material 10, and the end cap 50 can be attached to the flashing material 10 by pressing the end cap 50 against the end of the flashing material 10. This prevents water from seeping into the interior of the flashing material 10 through the opening 10a at the end of the flashing material 10. In this case, a recess may be formed on the opposing surface 52b of the end cap 50 that can accommodate the vertical plate portion 91c of the fixing portion 91 when the end cap 50 is attached to the flashing material 10. This effectively prevents water from seeping into the interior of the flashing material 10 through the opening 10a.

[0062] As a modified example, the water-stopping material 62 does not have to be attached to the end cap body 51. In other words, the end cap (end cap body 51) and the water-stopping material (water-stopping material 62) may be handled as separate bodies.

[0063] Screw holes 21d1 and 21e1 are formed along the entire length of the flashing material 10 in the left-right direction A. Therefore, no matter where the flashing material 10 is cut in the left-right direction A to adjust the length, screw holes 21d1 and 21e1 are present at the end of the cut flashing material 10. Therefore, it is possible to attach end caps 50 with screws 81 to the end of the cut flashing material 10.

[0064] Additionally, a water-expansive material 41 is disposed on the entire underside of the portion of the support portion 19 rearward of the protrusion 19a, and the water-expansive material 41 is made of the same material as the water-expansive material 30. This makes it possible to effectively prevent water from seeping in between the support portion 19 and the foundation 101. The water-expansive material 41 may be a water-stopping material, but by using the water-expansive material, it can more effectively cope with larger gaps that occur due to unevenness on the top surface of the foundation 101.

[0065] In addition, a water-stopping material 42 is attached to the rear surface of the upper rear wall 16a. This makes it possible to prevent water from entering between the mounting portion 11 and the base 103. In addition, a water-stopping material 43 is attached to the underside of the mounting plate portion 17b. This makes it possible to prevent water from entering between the mounting plate portion 17b of the detachable portion 3 and the support portion 19 of the main body portion 2. This makes it possible to prevent water from entering the interior side of the foundation 101 through the ventilation hole 16c of the flashing material 10 and the ventilation hole 102a of the foundation packing 102.

[0066] While the preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and various modifications are possible within the scope of the claims. For example, the end cap body 51 may have only the sealing portion 52. In other words, the end cap body 51 may not have the vertical flange portion 53 or the horizontal flange portion 54. Alternatively, the end cap body 51 may have the sealing portion 52 and either the vertical flange portion 53 or the horizontal flange portion 54.

[0067] Furthermore, the sealing portion 52 only needs to be configured to be able to seal the opening (part of the opening 10a) in the left-right direction A of the storage portion 14 of the water-repellent material 10. In other words, the sealing portion 52 does not need to seal the opening between the extension portion 12 and the lower plate portion 21 of the water-repellent material 10 (the other part of the opening 10a).

[0068] The screw holes 21d1, 21e1 do not have to be formed continuously over the entire length of the flashing material 10 in the left-right direction A. For example, the screw holes 21d1, 21e1 may be arranged discontinuously in series in the left-right direction A. Furthermore, the screw holes 21d1, 21e1 may be formed only at the ends of the flashing material 10 in the left-right direction A.

[0069] In the above-described embodiment of the present invention, end caps were described as an example of a flashing element. However, the end caps may also function as joints. For example, the vertical flanges 53 and horizontal flanges 54 of the end caps 50 of adjacent flashing units 1 may be overlapped, connected using the holes 53a, and screwed to the base 103. In this case, it is preferable to attach a water-stopping material 63 and a water-expansion material 64 to the indoor-facing surfaces of the vertical flanges 53 and horizontal flanges 54 of the end cap 50 of the flashing unit 1 that is placed indoors. Alternatively, the vertical flanges 53 and horizontal flanges 54 of the end caps 50 may be lengthened and the right and left ends of the flashing element 10 may be butted together to form a cubic frame-like inside corner, or an outside corner, to create an outside or inside corner element. In short, the flashing element of the present invention broadly encompasses elements that can be secured by covering the ends of the flashing element with screws. [Explanation of symbols]
