Description

[Technical Field]

[0001] The present invention relates to a ventilation structure, and more particularly to a ventilation structure installed on the coping, eaves or eaves at the upper end of a structure such as a fence, balcony railing or parapet. [Background technology]

[0002] Conventionally, the following technologies have been proposed as ventilation structures used to provide ventilation and prevent corrosion, cracks, etc. in the cappings installed at the top ends of structures (standing structures) such as fences, balcony railings, and parapets.

[0003] Patent Document 1 discloses a ventilation structure under a coping board in which a ventilation member is installed above an exterior wall base material and an exterior wall material. The ventilation member is a laminated body of a corrugated cardboard structure made of synthetic resin, and has a large number of through-holes of a predetermined size formed therein. This allows air to pass from the inside to the outside while providing a waterproof function to prevent rainwater and the like from passing through the ventilation member and entering the interior of the building structure, and allows ventilation to be achieved without accumulating moist air under the coping board.

[0004] The coping structure disclosed in Patent Document 2 uses a ventilation member with the same configuration as the ventilation member described in Patent Document 1, and further includes a front curtain portion that extends vertically outward from the ventilation member. By fastening the lower end of the front curtain portion with a coping cover, it can be fastened to the upper end of the frame without driving screws, preventing water from seeping into the frame through the screwed points. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-108314 [Patent Document 2] Japanese Patent Application Publication No. 2018-127883 Summary of the Invention [Problem to be solved by the invention]

[0006] In conventional ventilation structures such as those disclosed in Patent Documents 1 and 2, the ventilation members have a specific structure, but there is still room for improvement in their ventilation and waterproofing functions.

[0007] In addition, in conventional ventilation structures, caulking material was used to fill the area between the upper end of the exterior wall material and the ventilation member, but applying it to areas that are difficult to see below the fascia was time-consuming.

[0008] The present invention has been made to solve the above-mentioned problems, and has an object to provide a ventilation structure having excellent ventilation and waterproofing functions. [Means for solving the problem]

[0009] In order to achieve the above object, the invention described in claim 1 is a ventilation structure that is installed above an exterior wall material and extends in the longitudinal direction, and includes a frame body having a first vertical section that extends vertically when installed, a first horizontal section that extends from the upper end of the first vertical section toward the outdoors, and a second vertical section that extends vertically downward from a part of the first horizontal section and has a through hole formed therein, and a ventilation member that has ventilation functions from indoors to outdoors and waterproofing functions inside the frame body, and the ventilation member includes a first baffle plate that extends vertically so as to cross the ventilation path from indoors to outdoors and has a first air hole formed therein, and a second baffle plate that extends vertically outward from the first baffle plate at a predetermined distance and has a second air hole formed therein.

[0010] With this configuration, the second vertical portion, the first baffle plate and the second baffle plate prevent rainwater from entering, while the through hole, the first air vent and the second air vent ensure an air path from indoors to outdoors.

[0011] The invention described in claim 2 is the configuration of the invention described in claim 1, in which the ventilation member is formed by combining three U-shaped members, and the U-shaped members have a roughly U-shaped short-side cross-sectional shape including a vertical surface portion, an upper surface portion, and a lower surface portion, and the vertical surface portion has a plurality of cut-out holes formed at predetermined intervals in the longitudinal direction that rise toward the open side of the short-side cross-sectional shape, and the three U-shaped members include a first U-shaped member with its open side facing outdoors, a second U-shaped member whose open side faces the first U-shaped member and whose upper surface portions and lower surface portions are overlapped and combined, and a third U-shaped member whose open side faces outdoors and is arranged so that its vertical surface portions are in contact with the second U-shaped member and the positions of its cut-out holes are aligned.

[0012] With this configuration, the air from inside the building is discharged to the outside through the cut-and-raised holes.

[0013] The invention as set forth in claim 3 is the configuration of the invention as set forth in claim 1 or claim 2, wherein the through-hole is provided in a lower half region in the vertical direction of the second vertical portion.

[0014] This configuration ensures sufficient ventilation while improving waterproofing.

[0015] The invention described in claim 4 is the configuration of the invention described in any one of claims 1 to 3, in which the frame body further comprises a second horizontal portion extending from the lower end of the second vertical portion toward the interior of the room, and the ventilation member is fixed to the second horizontal portion.

[0016] With this configuration, the first baffle plate and the second baffle plate are sandwiched between the first horizontal portion and the second horizontal portion at the top and bottom.

[0017] The invention described in claim 5 is the same as the invention described in claim 4, but further includes a drain hole provided at the connection point between the second vertical section and the second horizontal section, which drains infiltrating rainwater to the outside.

[0018] With this configuration, even if a small amount of rainwater gets in, it will be discharged to the outside.

[0019] The invention described in claim 6 is the same as the configuration of any of the inventions described in claims 1 to 5, further comprising a front hanging portion extending vertically outward from the second vertical portion at a predetermined distance, and a connecting portion connecting the first horizontal portion and the front hanging portion.

[0020] This configuration generates turbulent air flowing into the space between the front hanging portion and the second vertical portion. Also, a coping cover can be hung and fixed on the lower end of the front hanging portion.

[0021] The invention described in claim 7 is the configuration of the invention described in any one of claims 1 to 6, further comprising an elastically deformable cushioning material installed between the ventilation member and the exterior wall material.

[0022] With this configuration, the space between the ventilation member and the exterior wall material can be filled with the buffer material.

[0023] The invention described in claim 8 is a configuration of the invention described in any one of claims 1 to 7, in which the exterior wall material is attached via a furring strip attached to the outer surface of the exterior wall base material, and the first vertical part of the frame body is installed so as to be inserted into the gap between the exterior wall base material and the furring strip.

[0024] This configuration makes it easier to position the frame. [Effects of the Invention]

[0025] As explained above, the invention described in claim 1 prevents rainwater from entering by the second vertical portion, the first baffle plate, and the second baffle plate, while ensuring a ventilation path from indoors to outdoors by the through holes, the first air vent, and the second air vent, thereby exhibiting excellent ventilation and waterproofing functions.

[0026] The invention of claim 2 has the same effect as the invention of claim 1, and in addition, improves the stability of the ventilation path because air from inside the room is discharged to the outside through the cut-and-raised holes.

[0027] The invention of claim 3 has the same effect as the invention of claim 1 or 2, and in addition, it has improved waterproofing while ensuring sufficient ventilation, allowing the structure to be made smaller.

[0028] The invention described in claim 4 has the effect of any of the inventions described in claims 1 to 3, and in addition, the first baffle plate and the second baffle plate are sandwiched between the first horizontal portion and the second horizontal portion at the top and bottom, thereby improving the stability of installation.

[0029] The invention described in claim 5 has the effect of the invention described in claim 4, and in addition, improves waterproofing function by discharging even a small amount of rainwater to the outside even if it penetrates.

[0030] The invention of claim 6 has the effect of any of the inventions of claims 1 to 5, and in addition generates turbulent air flow in the space between the front curtain portion and the second vertical portion, thereby further preventing rainwater from seeping in. Also, since a coping cover can be hung and fixed to the lower end of the front curtain portion, it can be attached without driving screws or the like into the upper end of the body.

[0031] In addition to the effects of the inventions described in any of claims 1 to 6, the invention described in claim 7 can fill the space between the ventilation component and the exterior wall material with cushioning material, eliminating the need for caulking, reducing the installation process, and making replacement easier.

[0032] The invention of claim 8 has the effect of the invention of any one of claims 1 to 7, and in addition, the frame body can be positioned easily, making the installation work more efficient. [Brief explanation of the drawings]

[Figure 7] 7 is a cross-sectional view showing a ventilation structure included in the Z portion shown in FIG. 6. [Figure 8] 10 is a cross-sectional view showing the fit when a ventilation structure according to a fourth embodiment of the present invention is used under the fascia of a house. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0034] FIG. 1 is a cross-sectional view showing the fit when a ventilation structure according to a first embodiment of the present invention is used under a coping board of a house.

[0035] The capping structure 1, capping 2, and ventilation structure 4 described below are elongated along the longitudinal direction of the main body 40 such as a fence, balcony railing, or parapet, and Fig. 1 shows the fit of the cross section in the short direction. The center of the figure is the indoor side, and both the left and right sides are the outdoor side.

[0036] Referring to the figure, a pair of exterior wall base materials 41a, 41b are arranged at the exterior end of the short side of the skeleton 40, with a pair of furring strips 42a, 42b provided on their outer surfaces. Further outward (on the exterior side) of these are a pair of exterior wall materials 45a, 45b, which are ceramic siding. The furring strips 42a, 42b are arranged at predetermined intervals in the longitudinal direction (not shown), and these intervals form air passages 48a, 48b. Furthermore, the space inside the skeleton 40 is connected to the air passages 48a, 48b (not shown) so that warm, humid air inside the skeleton 40 rises through the air passages 48a, 48b. A coping structure 1 is installed at the upper end of the skeleton 40.

[0037] The fascia structure 1 is mainly composed of a fascia 2 installed at the upper end of the main body 40 and a pair of ventilation structures 4a, 4b installed above a pair of exterior wall materials 45a, 45b and below the fascia 2.

[0038] The fascia 2 is made of metal and is installed via fascia mounting brackets 3 provided at predetermined intervals along the length of the upper end of the main body 40, covering the entire upper end of the main body 40 and the ventilation structures 4a, 4b from above to the outdoors, preventing rainwater from directly entering the main body 40 inside the fascia 2 from above.

[0039] Each of the pair of ventilation structures 4a, 4b is installed above the exterior wall materials 45a, 45b so as to cross the ventilation path from the inside to the outside (from the indoor side to the outdoor side) indicated by the dotted arrow 38 in the same figure.

[0040] 2 is a cross-sectional view showing the ventilation structure included in the portion X shown in FIG. 1, and FIG. 3 is an enlarged perspective view of the portion Y shown in FIG.

[0041] First, referring to Figure 2, the ventilation structure 4b is mainly composed of a frame body 12 made of steel plate and a ventilation member 13 that is placed inside the frame body 12 and performs ventilation functions from indoors to outdoors and waterproof functions.

[0042] The frame 12 is mainly composed of a first vertical section 14 that extends vertically when installed, a first horizontal section 15 that extends substantially horizontally from the upper end of the first vertical section 14 toward the outdoors (toward the right in FIG. 2), and a second vertical section 16 that extends vertically downward from the outdoor end of the first horizontal section 15. The frame 12 also includes a second horizontal section 17 that extends from the lower end of the second vertical section 16 parallel to the first horizontal section 15 and a predetermined distance in the direction of the first vertical section 14 (toward the indoors). The second vertical section 16 has a plurality of through holes 18 formed at predetermined intervals along its length, and these through holes 18 are arranged to fit within an area A in the vertical lower half of the second vertical section 16. The advantages of this configuration will be described later.

[0043] The connecting angle between the first vertical section 14 and the first horizontal section 15, shown as θ1 in Figure 2, is set to 87°. Here, because the first vertical section 14 is installed vertically, the first horizontal section 15 and the second horizontal section 17 are each inclined downward by 3° toward the outdoors. In addition, at the connecting point between the second vertical section 16 and the second horizontal section 17, multiple drainage holes 19 are formed at predetermined intervals in the longitudinal direction to drain infiltrating rainwater to the outside.

[0044] Also, an inner (leftward in FIG. 2) end 20 of the second horizontal portion 17 is bent upward.

[0045] Next, the ventilation member 13 includes a first baffle plate 24 extending vertically across the ventilation path from the indoors to the outdoors, and a second baffle plate 26 extending vertically at a predetermined distance outward (towards the outdoors) from the first baffle plate 24. Furthermore, a first ventilation hole 25 through which air can pass is formed in the first baffle plate 24, and a second ventilation hole 27 is similarly formed in the second baffle plate 26.

[0046] With this configuration, the second vertical portion 16, the first baffle plate 24, and the second baffle plate 26 prevent rainwater from entering, while the through-holes 18, the first vent holes 25, and the second vent holes 27 ensure a ventilation path from the inside to the outside, as indicated by the arrow 38 in Fig. 1. Therefore, while air can circulate inside the body 40, there are what might be called three barriers to prevent the intrusion of water such as rainwater from the outside, and the ventilation structure 4b exhibits excellent ventilation and waterproofing functions.

[0047] At this time, because the through holes 18 are provided in the region A in the vertical lower half of the second vertical portion 16 as described above, even if rainwater tries to infiltrate with wind blowing from the outside, it will first be blown into the space 30 above the outside of the second vertical portion 16, and after its momentum is reduced, it will come into contact with the through holes 18 in the second vertical portion 16. Therefore, sufficient ventilation function is ensured without providing through holes 18 over the entire second vertical portion 16, and waterproof function is improved, so the number of U-shaped members constituting the ventilation member 13 (described later) can be reduced to a minimum of three, thereby making it possible to miniaturize the structure.

[0048] As mentioned above, drainage holes 19 are provided at the connection points between the second vertical section 16 and the second horizontal section 17, allowing even a small amount of rainwater to be drained to the outside, further improving the waterproofing function. Furthermore, as mentioned above, the first horizontal section 15 and the second horizontal section 17 are inclined downward at 3° toward the outdoors, so that infiltrating rainwater is guided to the drainage holes 19, further improving the waterproofing function.

[0049] Moreover, the above-mentioned ventilation member 13 is fixed to the second horizontal portion 17 of the frame body 12 using rivets 21a, 21b. With this configuration, the top and bottom of the first baffle plate 24 and the second baffle plate 26 are sandwiched between the first horizontal portion 15 and the second horizontal portion 17, thereby improving the stability of the installation.

[0050] 1, an elastically deformable EPDM buffer material 22 is provided between the second horizontal section 17 of the ventilation structure 4b and the exterior wall material 45b. By installing the ventilation structure 4b above the exterior wall material 45b with the buffer material 22 attached in advance, the space between the ventilation member 13 and the exterior wall material 45b can be filled with the buffer material 22, eliminating the need to caulk the hard-to-see area below the coping 2 and reducing the installation process. Replacement is also easier.

[0051] The ventilation structure 4a on the other side of the ventilation structure 4b described above has the same configuration, so that excellent ventilation and waterproofing functions are exhibited on both sides facing the outdoors.

[0052] Next, a method for constructing the ventilation member 13 in such ventilation structures 4a and 4b will be described.

[0053] FIG. 4 is a schematic diagram showing an assembly process for the ventilation member shown in FIG.

[0054] Referring to the figure, the ventilation member 13 is configured by combining a first U-shaped member 51 with a second U-shaped member 61 and a third U-shaped member 71 having the same shape as the first U-shaped member 51.

[0055] The first U-shaped member 51 is constructed by bending a long metal plate into a generally U-shape in cross section in the short side direction as shown in the drawing, to form a vertical surface portion 52, an upper surface portion 53, and a lower surface portion 54. In addition, a plurality of cut-out holes 55 are formed in the vertical surface portion 52 at predetermined intervals in the longitudinal direction, rising toward an open side 56 in the cross section in the short side direction.

[0056] When assembling the ventilation member 13, first, referring to Figure 4 (1), the open side 56 of the first U-shaped member 51 and the open side 66 of the second U-shaped member 61 are placed opposite each other and brought close to each other as indicated by arrows 60a and 60b, and then, as shown in Figure 4 (2), the upper surface portions 53, 63 and lower surface portions 54, 64 of each are overlapped and combined to form an approximately rectangular cross-sectional shape in the short direction.

[0057] Next, the third U-shaped member 71 is positioned so that its open side 76 faces outdoors (the same direction as the open side 56 of the first U-shaped member 51), and as shown by arrow 70, the vertical surface portion 72 of the third U-shaped member 71 is in contact with the vertical surface portion 62 of the second U-shaped member 61, and the positions (heights) of the cut-out holes 75 and the cut-out holes 65 are aligned, thereby completing the assembly of the ventilation member 13.

[0058] In the ventilation member 13 assembled in this manner, the vertical surface portion 52 of the first U-shaped member 51 functions as the first baffle plate 24, and the cut-and-raised hole 55 functions as the first vent hole 25. Furthermore, at a distance held by the upper surface portions 53, 63 and the lower surface portions 54, 64 outward from the first baffle plate 24, the vertical surface portion 62 of the second U-shaped member 61 and the vertical surface portion 72 of the third U-shaped member 71 function as the second baffle plate 26, and the cut-and-raised holes 65, 75 function as the second vent hole 27.

[0059] With this configuration, the stability of the ventilation path is improved because air from indoors is discharged to the outdoors through the cut-and-raised holes 55, 65, and 75. In addition, because the first baffle plate 24 and the second baffle plate 26 are positioned at a certain distance apart, the ventilation path from indoors to outdoors is less likely to become clogged, and waterproofing is improved.

[0060] Then, referring back to Figures 1 and 2, the ventilation structure 4b is formed by placing the ventilation member 13 inside the frame body 12 (below the first horizontal portion 15 and inward from the second vertical portion 16) which is formed by bending a metal plate.

[0061] Furthermore, when installing the ventilation structure 4b, first widen the gap between the upper end of the exterior wall base material 41b and the upper end of the furring strip 42b to form a gap, and then insert the first vertical portion 14 of the frame body 12 of the ventilation structure 4b into the gap.

[0062] This makes it easier to position the frame 12, making the installation work more efficient.

[0063] In this way, the ventilation structure 4b installed above the exterior wall material 45b prevents rainwater from entering while reducing the risk of clogging, as described above, and ensures a ventilation path from indoors to outdoors, thereby providing excellent ventilation and waterproofing functions.

[0064] Next, FIG. 5 is a cross-sectional view showing the fit when a ventilation structure according to a second embodiment of the present invention is used under a coping board of a house.

[0065] The ventilation structure 5 according to the second embodiment of the present invention has a configuration basically similar to that of the ventilation structure 4 according to the first embodiment described above, and therefore the following description will focus on the differences.

[0066] Referring to the figure, single-hat joiners 32a, 32b are provided below each of the ventilation structures 5a, 5b, without providing cushioning material 22 (see FIG. 1). The single-hat joiners 32a, 32b extend in the longitudinal direction and have hat portions 33a, 33b with a U-shaped cross-section. The single-hat joiners 32a, 32b are fixed to the furring strips 42a, 42b, respectively, with nails or the like so that the lower surfaces of the hat portions 33a, 33b contact the upper ends of the exterior wall materials 45a, 45b and the upper surfaces contact the lower parts of the ventilation structures 5a, 5b.

[0067] The gap between the lower part of the ventilation structure 5a, 5b and the upper end of the exterior wall material 45a, 45b is filled using caulking materials 34a, 34b on the hat parts 33a, 33b of the one-hat joiners 32a, 32b installed in this manner.

[0068] In this way, it is possible to use the caulking materials 34a and 34b without using the buffer material 22 for the ventilation structures 5a and 5b.

[0069] Next, Figure 6 is a cross-sectional view showing the fit when a ventilation structure according to the third embodiment of the present invention is used under the fascia of a house, and Figure 7 is a cross-sectional view showing the ventilation structure included in the Z portion shown in Figure 6.

[0070] The ventilation structure 6 according to the third embodiment of the present invention has a configuration basically similar to that of the ventilation structure 4 according to the first embodiment described above, and therefore the following description will focus on the differences.

[0071] 6, ventilation structures 6a and 6b are provided above exterior wall materials 45a and 45b with buffer materials 22a and 22b interposed between them. Furthermore, top panel 81 of coping board 78 is inclined downward from one end 79, which is on the outdoor side of the house, to the other end 80, which is on the indoor side. Therefore, when rain falls on coping board 78, rainwater is guided to flow toward the other end 80 of coping board 78 (the indoor side of the house), preventing traces of rainwater from remaining on the outdoor side of the house.

[0072] In addition, an elastically deformable buffer body 82 with a trapezoidal cross section is provided between the head board 78 and the body 40, and its upper surface fits along the slope of the top plate portion 81. This stabilizes the shape of the head board 78 even when a load is applied to the top plate portion 81.

[0073] The lower ends of one end 79 and the other end 80 of the cap board 78 are bent upward and inward to form folded-back portions 83a and 83b, respectively.

[0074] Next, referring also to FIG. 7, the ventilation structure 6b includes, in addition to the structure of the ventilation structure 4b in the first embodiment described above, a front curtain portion 89 extending vertically outward from the second vertical portion 86 at a predetermined distance, and a connecting portion 87 connecting the first horizontal portion 85 and the front curtain portion 89. As shown in FIG. 6, the folded portion 83b of the other end 80 of the head board 78 is hooked onto the lower end 90 of the front curtain portion 89, and the same is true for the folded portion 83a of the one end 79. The other end 80 is fixed to the front curtain portion 89 with screws or the like. In this way, the head board 78 can be attached to the top panel portion 81 or the upper end of the frame 40 without driving in any fixtures such as screws. This eliminates the need for any attachment holes, and prevents rainwater from seeping into the frame 40 through such attachment holes.

[0075] Furthermore, the lower end 90 of the hanging portion 89 is located vertically lower than the through-hole 88 of the second vertical portion 86. This prevents wind and rain from blowing in from the side directly into the ventilation structure 6b.

[0076] Furthermore, by positioning the front hanging portion 89 in this manner at a predetermined distance outward from the second vertical portion 86 via the connecting portion 87, turbulence is generated in the air flowing into the space between the front hanging portion 89 and the second vertical portion 86, as shown by arrow 84 in Figure 7, which has a synergistic effect in addition to the fact that the through hole 88 in the second vertical portion 86 is formed in the vertical lower half of the second vertical portion 86, further preventing rainwater from entering.

[0077] Next, FIG. 8 is a cross-sectional view showing the fit when a ventilation structure according to a fourth embodiment of the present invention is used under a coping board of a house.

[0078] Referring to the figure, the ventilation structures 7a and 7b have the same structure as the ventilation structures 6a and 6b according to the third embodiment described above. Also, like the ventilation structures 5a and 5b according to the second embodiment described above, they are installed above the exterior wall materials 45a and 45b via one-side hat joiners 32a and 32b.

[0079] In this way, even in the ventilation structures 7a and 7b having the front hanging portions 99a and 99b, it is possible to perform caulking using the one-hat joiners 32a and 32b.

[0080] In the above embodiments, the capping and ventilation structure frame are made of steel plate, but they may be made of other materials, such as aluminum or synthetic resin. They may also be integrally formed by extrusion molding.

[0081] In addition, in each of the above embodiments, the ventilation member has a specific configuration, but it may have another configuration as long as it includes a first baffle plate having a first vent hole formed therein and a second baffle plate provided outward from the first baffle plate at a predetermined distance and having a second vent hole formed therein. For example, there may be mentioned a structure in which two steel plates having vent holes formed therein and extending in the longitudinal direction are fixed to the inside of a frame at a predetermined distance apart.

[0082] Furthermore, in each of the above embodiments, the through-holes are provided in the lower half region of the second vertical portion in the vertical direction, but they may be provided in other locations on the second vertical portion.

[0083] Furthermore, in each of the above-described embodiments, the frame body is provided with a second horizontal portion, but the frame body may not be provided with a second horizontal portion, and the first baffle plate and the second baffle plate may be fixed to the upper part of the frame body, for example.

[0084] Furthermore, in each of the above embodiments, a drain hole is formed at the connection point between the second vertical section and the second horizontal section, but the drain hole does not have to be formed, and may be provided in another location.

[0085] Furthermore, in the above first and third embodiments, cushioning material made of a specific material is provided, but the cushioning material may be made of other materials as long as it is elastically deformable and can fill the area between the ventilation member and the exterior wall material.

[0086] Furthermore, in each of the above embodiments, the first vertical portion of the frame body was installed by inserting it into the gap between the exterior wall base material and the furring strip, but it may be installed in any other way as long as the position can be fixed.

[0087] Furthermore, in each of the above embodiments, the cross-sectional shape of the top plate in the short direction was specific, but other shapes may be used as long as they can guide rainwater and the like falling from above downward and prevent water from accumulating at the top of the top plate.

[0088] Furthermore, in each of the above embodiments, the outer surface of the front flap of the ventilation member and the inner surface of the first side wall of the coping cover may be joined in a liquid-tight manner using adhesive, double-sided tape, etc. By configuring in this manner, even if rainwater attempts to blow horizontally or diagonally downward toward the coping structure and seeps in through the folded portion, the water will flow upward between the outer surface of the front flap and the inner surface of the end of the coping due to surface tension, etc., preventing water from seeping into the space under the coping.

[0089] Furthermore, in each of the above-described embodiments, the end of the coping and the front portion of the ventilation structure are attached with screws, but other attachment means may also be used.

[0090] Furthermore, in each of the above embodiments, the first horizontal section, the second horizontal section, and the connecting section are inclined downward at a specific angle toward the outside, but they may be inclined downward at another angle so that water that has seeped in through the through-holes can be discharged to the outside through the drainage holes. Also, they may be provided horizontally without inclining downward.

[0091] Furthermore, in each of the above embodiments, the structure of the part below the fascia board was specific, but other structures may be used as long as the part is located between the exterior wall material and the fascia board installed above it.

[0092] Furthermore, in each of the above embodiments, the frame of the ventilation member has a specific structure, but it may have another structure.

[0093] Furthermore, in each of the above-described embodiments, the lower end of the hanging portion is located below the through-hole of the second vertical portion, but it does not have to be located so far below.
