A flashing 10 according to a first embodiment will now be described with reference to
The building 1 is, for example, a house that includes a building body 2. The building body 2 includes a roof 2A and an outer wall 3. The roof 2A includes a roof surface 2B that is parallel to or inclined with respect to the horizontal direction. The building 1 further includes an outdoor living space 4. Examples of the outdoor living space 4 include a terrace, a balcony, and a veranda.
As shown in
In one example, the roof 2A projects out of the outer wall 3 to cover the outdoor living space 4. Examples of the outdoor living space 4 include a terrace, a balcony, and a veranda. In such a roof 2A, one or more lateral members 5A are arranged above the outdoor living space 4. In the present embodiment, one lateral member 5A (hereinafter referred to as an outer lateral member 6) of the lateral members 5A that support the roof 2A is arranged above the outdoor living space 4. The portion of the roof 2A facing the floor surface of the outdoor living space 4 is closed by a cover member 7.
The space between the outer lateral member 6 and the outer wall 3 is closed by a first cover member 7A. The first cover member 7A is arranged to cover a lower surface 6A of the outer lateral member 6. The space between a side surface 6B of the outer lateral member 6 and an eaves edge member 2C is closed by a second cover member 7B.
The second cover member 7B is located at a higher position than the first cover member 7A. More specifically, the second cover member 7B is arranged such that its lower surface intersects the side surface 6B of the outer lateral member 6. The lower part of the side surface 6B of the outer lateral member 6 is located at a lower position than the second cover member 7B. The side surface of the outer lateral member 6 is covered by the exterior part 8. The exterior part 8 is preferably formed using a finishing material that is waterproof and light-resistant. Examples of the finishing material include a siding and a tile. The exterior part 8 is attached to the outer lateral member 6 by a furring strip 9. A ventilation passage VP through which air passes is provided between the exterior part 8 and the outer lateral member 6. The flashing 10 is arranged below the exterior part 8. The flashing 10 prevents the rainwater on the exterior part 8 from moving to the outer lateral member 6 via the lower surface of the exterior part 8. Further, the flashing hides the lower surface of the exterior part 8, thereby improving the design of the lower surface of the roof 2A, which projects on the upper side of the outdoor living space 4.
Referring to
The flashing member 11 is fixed to the outer lateral member 6 by fixing the attachment portion 12 to the outer lateral member 6 using a screw. More specifically, the attachment portion 12 is arranged in the ventilation passage VP between the exterior part 8 and the outer lateral member 6 in a state where the flashing member 11 is arranged below the exterior part 8. The body of the attachment portion 12 includes a first main surface 12A and a second main surface 12B. The body of the attachment portion 12 is, for example, plate-shaped. At least a part of the first main surface 12A faces the exterior part 8 in the state where the flashing member 11 is arranged below the exterior part 8. At least a part of the second main surface 12B faces the outer lateral member 6 in the state where the flashing member 11 is arranged below the exterior part 8.
The guide 13 is spaced apart from the lower surface of the exterior part 8 in the state where the flashing member 11 is arranged below the exterior part 8. The body of the guide 13 includes a first main surface 13A and a second main surface 13B. The body of the guide 13 is, for example, plate-shaped. The first main surface 13A of the guide 13 is continuous with the first main surface 12A of the attachment portion 12. The second main surface 13B of the guide 13 is continuous with the second main surface 12B of the attachment portion 12. Angle θ, formed by the first main surface 12A and the first main surface 13A, is preferably greater than or equal to 90°. Angle θ, formed by the first main surface 12A and the first main surface 13A, is preferably less than or equal to 120°.
The flashing member 11 further includes an extension 14. The extension 14 is continuous with the guide 13. The extension 14 prevents the water flowing on the first main surface 13A of the guide 13 from flowing to the second main surface 13B of the guide 13. More specifically, the attachment portion 12 is arranged at one end of the guide 13 in the width direction and the extension 14 is arranged at the other end. Further, in the state where the flashing member 11 is arranged below the exterior part 8, the extension 14 is configured to extend downward from the end of the guide 13 opposite the portion where the attachment portion 12 is arranged.
The flashing member 11 includes a coupling portion 20. The flashing member 11 is used to couple the flashing member 11 to an additional flashing member 111. The additional flashing member 111 has the same components as the flashing member 11. The coupling portion 20 is arranged at least on the first main surface 13A of the guide 13. In the present embodiment, the coupling portion 20 is further arranged on the first main surface 12A of the attachment portion 12.
The coupling portion 20 includes a retainer 21 that retains a coupling member 30. In a state where the flashing member 11 is coupled to the additional flashing member 111 by the coupling member 30, the retainer 21 is configured such that the second main surface 13B of the guide 13 of the flashing member 11 is flush with a second main surface 113B of a guide 113 of the additional flashing member 111.
The retainer 21 includes a first protrusion 22 that protrudes from the first main surface 13A of the guide 13 and a second protrusion 23 that protrudes from the first main surface 12A of the attachment portion 12. The first protrusion 22 extends in a longitudinal direction XA of the guide 13. The second protrusion 23 extends in the longitudinal direction XA of the attachment portion 12.
The first protrusion 22 includes a body 22A that protrudes from the first main surface 13A and a movement restricting portion 22B that is orthogonal to the longitudinal direction XA of the body 22A. The movement restricting portion 22B is parallel to the first main surface 13A. The second protrusion 23 is parallel to the first main surface 13A.
The first main surface 13A, the first protrusion 22, and the second protrusion 23 define a retaining space S that retains the coupling member 30. The flashing member 11 is coupled to the additional flashing member 111 by retaining a part of the coupling member 30 in the retaining space S of the flashing member 11 and retaining another part of the coupling member 30 in the retaining space S of the additional flashing member 111.
The coupling member 30 includes a body 31. The body 31 is a plate-shaped member including a first main surface 31A and a second main surface 31B. One of the first main surface 31A and the second main surface 31B contacts the movement restricting portion 22B of the first protrusion 22 and the second protrusion 23 during coupling. The other one of the first main surface 31A and the second main surface 31B contacts the first main surface 13A during coupling. The size of the body 31 is set according to the retaining space S.
The method for attaching the flashing 10 of the present embodiment will now be described with reference to
A worker brings the attachment portion 12 of the flashing member 11 into contact with the side surface 6B of the outer lateral member 6 to fixe the attachment portion 12 to the outer lateral member 6 using a screw. When the length of the flashing 10 including one flashing member 11 in the longitudinal direction XA is shorter than the length of the exterior part 8 in the horizontal direction, the worker couples the additional flashing member 111, which is separate from the flashing member 11. In such a manner, the length in the longitudinal direction XA is made longer. More specifically, a part of the coupling member 30 is inserted into the retaining space S defined by the first main surface 13A, the first protrusion 22, and the second protrusion 23 of the flashing member 11. Another part of the coupling member 30 protrudes from the flashing member 11. The portion of the coupling member 30 protruding from the retainer 21 is inserted into the retaining space S defined by the additional flashing member 111. It is preferred that the adhesive 40 be applied to the first main surface 31A or the second main surface 31B of the coupling member 30, which contacts the first main surface 13A of the guide 13. In the state where the flashing member 11 is coupled to the additional flashing member 111 by the coupling member 30, the second main surface 13B of the guide 13 of the flashing member 11 is flush with the second main surface 113B of the guide 113 of the additional flashing member 111. Further, the first main surface 12A of the attachment portion 12 is flush with the first main surface 112A of the attachment portion 112 of the additional flashing member 111. The attachment portion 112 of the additional flashing member 111 is fixed to the side surface 6B of the outer lateral member 6 using a screw.
When the length of the flashing 10, including the flashing member 11 and the additional flashing member 111, in the longitudinal direction XA does not match the length of the exterior part 8 in the horizontal direction, the lengths are adjusted using the following means. When the length of the flashing 10, including the flashing member 11 and the additional flashing member 111, in the longitudinal direction XA is shorter than the length of the exterior part 8 in the horizontal direction, the length in the longitudinal direction XA is made longer by coupling a further additional flashing member 111. When the length of the flashing 10, including the flashing member 11 and the additional flashing member 111, in the longitudinal direction XA is greater than the length of the exterior part 8 in the horizontal direction, a part of the flashing member 11 or the additional flashing member 111 is cut using, for example, an electric saw. Such a means is used so that the length of the flashing 10 in the longitudinal direction XA matches the length of the exterior part 8 in the horizontal direction.
The operation of the flashing 10 the present embodiment will now be described.
When strong wind or the like blows, the rainwater in contact with the exterior part 8 contacts the first main surface 13A of the guide 13 and moves to the extension 14 to fall downward. The configuration of the guide 13 and the extension 14 prevents the rainwater in contact with the exterior part 8 from contacting the outer lateral member 6. In addition, the arrangement of the guide 13 of the flashing 10 below the opening of the lower end of the ventilation passage VP prevents the rainwater from reaching the inside of the ventilation passage VP.
The advantages of the flashing member 11 of the first embodiment will now be described.
The flashing 10 of the present embodiment includes the coupling portion 20 that couples the flashing member 11 to the additional flashing member 111. Thus, when the flashing member 11 and the flashing member 111 are arranged below the exterior part 8, one of the flashing member 11 and the flashing member 111 can be easily positioned relative to the other one.
The flashing 10 of the present embodiment allows one of the flashing member 11 and the flashing member 111 to be easily positioned relative to the other one when the flashing member 11 and the flashing member 111 are arranged below the exterior part 8.
The flashing 10 of the present embodiment increases a coupling force of the coupling member 30. When the adhesive 40 has a sealing effect, the gap formed between the coupling member 30 and the coupling portion 20 is sealed. This prevents the rainwater in contact with the first main surface 13A of the guide 13 from flowing through the gap to the second main surface 13B.
The flashing 10 of the present embodiment includes no gap between the flashing member 11 and the additional flashing member 111 and thus has an improved design.
In the flashing 10 of the present embodiment, the flashing member 11 is made of aluminum. In a case where the flashing member 11 is coupled to the additional flashing member 111, the length of the exterior part 8 in the horizontal direction may be longer than the length of the flashing members coupled to each other in the longitudinal direction XA. This may lower the appearance and the flashing effect. However, the flashing member 11 is made of aluminum and thus can be easily cut.
A flashing 100 according to a second embodiment will now be described with reference to
The first flashing member 211 includes at least one of a first coupling portion 20A or a second coupling portion 20B. The second flashing member 311 includes at least the other one of the first coupling portion 20A or the second coupling portion 20B. In the present embodiment, the first flashing member 211 includes the first coupling portion 20A, and the second flashing member 311 includes the second coupling portion 20B. The first coupling portion 20A and the second coupling portion 20B are couplable to each other.
The first coupling portion 20A is arranged on a third main surface 213C of a guide 213. The third main surface 213C connects a first main surface 213A and a second main surface 213B of the first flashing member 211 to each other at an end of the first flashing member 211 in the longitudinal direction XA. The first coupling portion 20A has a projected shape that protrudes from the third main surface 213C.
The second coupling portion 20B is arranged in a third main surface 313C. The third main surface 313C connects a first main surface 313A and a second main surface 313B of the second flashing member 311 to each other at an end of the second flashing member 311 in the longitudinal direction XA. The second coupling portion 20B has a recessed shape recessed from the third main surface 313C.
As shown in
The flashing 100 of the second embodiment provides the following advantages.
The flashing 100 of the present embodiment allows one of the flashing member 211 and the second flashing member 311 to be easily positioned relative to the other one when the flashing member 211 and the second flashing member 311 are arranged below the exterior part 8.
The description of the embodiments is an exemplification of the mode that the flashing member according to the present invention can take, and is not intended to limit the mode. In addition to the embodiments, the flashing member according to the present invention can take, for example, a mode in which the following modifications of each embodiment are combined and a mode in which at least two modifications that remain consistent each other are combined.
In the first embodiment, the second protrusion 23 may be arranged on the first main surface 13A of the guide 13. In this case, the second protrusion 23 includes a body and a movement restricting portion in the same manner as the first protrusion 22.
In the first flashing member 211 of the second embodiment, the first coupling portion 20A may be arranged on a third main surface 213C that is provided at one end of the first flashing member 211 in the longitudinal direction XA, and the second coupling portion 20B may be arranged on a third main surface 213C that is provided at the other end of the first flashing member 211 in the longitudinal direction XA. Since one first flashing member 211 includes the first coupling portion 20A and the second coupling portion 20B, flashing members can be easily coupled to each other in the case of extension in the longitudinal direction XA.
In the building 1, the target on which the flashing 10 is arranged is not limited to the examples of the present embodiment. For example, the flashing 10 may be arranged below the exterior part of the vertical wall of a veranda. The flashing 10 may be arranged below the exterior part of the wall of a bay window.
