The ventilation member 100 includes an inner member 10 having a first vertical portion 11 extending in the vertical direction and a first horizontal portion 12 extending in the horizontal direction from the first vertical portion 11 and formed with a joined portion 12f. there is The ventilation member 100 includes a second horizontal portion 23 formed with a joining portion 23f that can be joined to the joined portion 12f, and a second vertical portion extending vertically from the second horizontal portion 23 and having an outside air vent 24h. 24 , a third horizontal portion 25 extending horizontally from the second vertical portion 24 , and a breathable waterproof filter 26 . Thus, the ventilation member 100 includes the inner member 10 having the joined portion 12f and the outer member 20 having the joined portion 23f. The ventilation member 100 may be made of resin such as polyvinyl chloride, polyethylene, or polypropylene.
Therefore, as shown in FIG. 1 , after the inner member 10 is provided on the base member 3 , the outer member 20 can be attached to the inner member 10 at any timing to assemble the ventilation member 100 . For example, after the inner member 10 is provided on the outer side of the upper portion of the base member 3, a felt sheet having protrusions 72 formed thereon as the spacer 7 is applied from the outside of the base member 3 to the first vertical portion 11 of the inner member 10. The exterior material 6 can be molded by sticking it so as to straddle it to the outside and then applying mortar on site. Then, as shown in FIG. 6, the outer member 20 can be assembled with the inner member 10 at any timing.
Further, for example, when a furring strip is formed as a spacer 7 on the outer side of the base member 3, after the inner member 10 is provided on the outer side of the upper part of the furring strip, the prefabricated exterior material 6 is attached to the waist at an arbitrary timing. It can be provided so as to straddle from the outside of the edge to the outside of the first vertical portion 11 of the inner member 10 . After inserting and providing the first vertical portion 11 of the inner member 10 between the inner side of the upper part of the furring strip and the outer side of the base member 3, the prefabricated exterior material 6 is attached to the furring strip at an arbitrary timing. may be provided outside the Then, the outer member 20 can be assembled with the inner member 10 at any timing.
The ventilation member 100 in which the inner member 10 and the outer member 20 are assembled may be attached to the outer side of the base member 3 or the outer side of the spacer 7 . That is, the ventilation member 100 in which the inner member 10 and the outer member 20 are assembled may be directly attached to the outer side of the base member 3, and may be directly attached to the outer side of the furring line provided on the outer side of the base member 3. may
In this manner, the ventilation member 100 can be installed at any timing regardless of whether the spacer 7 of the wall 1 is a sheet or a furring strip, and regardless of the timing of construction of the exterior material 6. It can be attached to the wall 1. Therefore, it is possible to provide the ventilation member 100 that can be easily attached to the wall 1 without being restricted by the structure of the wall 1 and the construction method of the wall 1 .

The first vertical portion 11 is a plate-like body extending along the longitudinal direction of the wall 1 . The first vertical portion 11 is arranged along the surface of the base member 3 of the wall 1 . For example, as shown in FIG. 1, the first vertical portion 11 is arranged on the outer surface of the base member 3 or the spacer 7, and a fixing means such as a nail, a screw, or an adhesive penetrates through the first vertical portion 11. (not shown) may be fixed to the base member 3 or the spacer 7 . Further, the first vertical portion 11 may be sandwiched between the base member 3 and the spacer 7 and supported by the pressure received from the base member 3 and the spacer 7 , for example.
A lower end portion of the first vertical portion 11 may have a tapered portion 11t tapered downward. Moreover, it is preferable that the tapered portion 11t is tapered so as to move inward as it goes downward. This makes it easier to insert the inner member 10 of the ventilation member 100 between the base member 3 and the spacer 7 . Further, even when the inner member 10 of the ventilation member 100 is arranged between the base member 3 and the spacer 7, the ventilation space in the transition portion T from the outer surface of the base member 3 to the outer surface of the first vertical portion 11 is maintained. V can be secured.

The first vertical portion 11 has an inner vent hole 11 h arranged to face the air-permeable waterproof filter 26 . The inner vent 11h may be a slit extending vertically. The inner vent 11h may be formed by arranging a plurality of slits extending in the vertical direction side by side in the longitudinal direction of the ventilation member 100 . As a result, for example, even when the inner member 10 is directly fixed so that the inner surface of the first vertical portion 11 is in contact with the outer surface of the furring strip, the air inside the wall 1 is allowed to flow between the adjacent furring strips. Ventilation can be made to pass through the inner vent hole 11h from the vent space V formed between them and to the breathable waterproof filter 26 and the outer vent hole 24h.

The first vertical portion 11 may have a positioning stopper 11s protruding outward. The stopper 11s may be locked to the inner vent 11h. For example, as shown in FIGS. 4 and 5, the stopper 11s may be suspended between at least two inner vents 11h that are separated from each other in the longitudinal direction and locked to the inner vents 11h. A plurality of stoppers 11s are provided, for example, at intervals of several tens of centimeters along the longitudinal direction. As a result, for example, even if the spacer 7 is inserted into the gap G in a state where the ventilation member 100 assembled with the inner member 10 and the outer member 20 is attached to the wall 1, the position of the upper end of the spacer 7 is kept at a predetermined position. can be regulated by a stopper 11s so as not to go above the level of . Therefore, the inner vent 11h can be prevented from being blocked by the spacer 7, and ventilation from the inner vent 11h can be ensured.

The first horizontal portion 12 has a joined portion 12f at its outer end. The joined portion 12f is, for example, bifurcated into an upper portion and a lower portion toward the end portion of the first horizontal portion 12, as shown in FIG. Sawtooth notches are formed on the lower surface of the upper portion and the upper surface of the lower portion of the joined portion 12f, respectively. A joint portion 23f of the outer member 20, which will be described later, is engaged with this notch.

The second horizontal portion 23 is arranged at substantially the same level (position in the vertical direction) as the first horizontal portion 12 . The second horizontal portion 23 has a joint portion 23f that can be joined to the joint portion 12f at its inner end. Saw-toothed notches are formed on the upper and lower surfaces of the joint portion 23f. The inner member 10 and the outer member 20 can be assembled by engaging the joint portion 23f with the joined portion 12f of the inner member 10. As shown in FIG.

The second vertical portion 24 is positioned at the outer end of the ventilation member 100 . Inside the second vertical portion 24, an air-permeable waterproof filter 26 is arranged. The second vertical portion 24 is provided with an outside air vent 24h.

The outside vent 24h is a hole that serves as an outlet for air (ventilation) passing through the interior of the wall 1. As shown in FIG. The outside air vent 24h may be a slit extending vertically. The outer air vent 24 h may have a plurality of vertically extending slits arranged side by side in the longitudinal direction of the ventilation member 100 . The inner side of the outer vent 24h is closed by the ventilation waterproof filter 26. - 特許庁As a result, the air inside the wall 1 passes through the ventilation space V from the bottom to the top, exits the waterproof ventilation filter 26 from the inside to the outside, and flows through the outside vent 24h from the inside to the outside. You can walk away.

The third horizontal portion 25 supports the ventilation waterproof filter 26 from below.

The third horizontal portion 25 extends toward the first vertical portion 11 and has a tongue 27 that is elastically deformable so as to close the gap G between the third horizontal portion 25 and the first vertical portion 11. good. The tongue 27 elastically urges the first vertical portion 11 or the spacer 7 from the outside toward the inside to prevent a large amount of rainwater from entering the inside of the ventilation member 100 when subjected to wind pressure. and cover the gap G. The tongue 27 may be made of soft plastic such as soft vinyl chloride or thermoplastic elastomer. Since the third horizontal portion 25 has the tongue 27 in this way, it is possible to prevent rainwater, insects, and the like from entering the ventilation member 100 through the gap G. Further, as shown in FIG. 1, even if the upper portion of the spacer 7 is inserted into the gap G, the space between the inner end of the third horizontal portion 25 and the outer surface of the spacer 7 can be blocked. As a result, it is possible to prevent rainwater, insects, and the like from entering the interior of the ventilation member 100 . In addition, it is possible to prevent the material of the exterior material 6 having fluidity, such as mortar, from entering the inside of the ventilation member 100 at the time of construction on site. Therefore, it is possible to secure a ventilation path in the wall 1, as indicated by the white arrow in FIG.
As shown in FIG. 1, the tongue 27 may have a cross-section that draws a downwardly convex arc. As a result, even if the spacer 7 is inserted from below through the gap G of the ventilation member 100 after the inner member 10 and the outer member 20 are assembled, the space between the outer surface of the spacer 7 and the third horizontal portion 25 is maintained. can be blocked.

The breathable waterproof filter 26 is permeable to air and impermeable to water. The air-permeable waterproof filter 26 is, for example, a foam made of resin such as polyurethane having open cells. The ventilation waterproof filter 26 is fixed to the outer member 20 . The ventilation waterproof filter 26 may be adhered to the third horizontal portion 25 . Since the ventilation member 100 includes the ventilation waterproof filter 26, the air inside the wall 1 can be released to the outside of the wall 1, and water, insects, etc. Intrusion into the interior can be prevented.

The part to be joined 12f and the joining part 23f may have a snap-fit structure that can be joined with one covering the upper surface and the lower surface of the other. As a result, the entry path of rainwater or the like from the upper surface of the ventilation member 100 into the inside of the ventilation member 100 can be made long and narrow, so that the watertightness of the upper portion of the ventilation member 100 can be ensured, and the assembly of the outer member 20 to the inner member 10 can be facilitated. Easy to do. Specifically, for example, as shown in FIG. 1, the jointed portion 12f is a portion that is bifurcated into an upper portion and a lower portion toward the end portion of the first horizontal portion 12 . Sawtooth notches are formed on the lower surface of the upper portion and the upper surface of the lower portion of the joined portion 12f, respectively. In addition, serrated notches are formed on the upper and lower surfaces of the joint portion 23f. Then, when the joining portion 23f is inserted between the upper portion and the lower portion of the portion to be joined 12f, the joining portion 23f pushes the upper portion and the lower portion of the portion to be joined 12f apart vertically. When the joint portion 23f advances toward the inner member 10, the joint portion 12f returns elastically, and the notch of the joint portion 12f engages with the notch of the joint portion 23f. In this manner, the inner member 10 and the outer member 20 can be easily assembled simply by pushing the outer member 20 toward the inner member 10 . Note that the snap-fit structure is not limited to the specific structure shown in FIG.

A locking hole H capable of locking the locking projection 31 of the end cap 30 (see FIGS. 2 and 3) may be formed between the joined portion 12f and the joint portion 23f. Since the space formed between the joined portion 12f and the joining portion 23f is used as the locking hole H in this manner, additional processing for forming the locking hole H can be omitted.

As shown in FIGS. 2 and 3, the vent member 100 may include an end cap 30 having a locking projection 31. As shown in FIGS. The end caps 30 cover and block both end faces of the ventilation member 100, thereby protecting the wall 1 from intrusion of rainwater, insects, etc. from the end faces. 2 and 3, illustration of the end cap 30 provided on one side of the ventilation member 100 in the longitudinal direction is omitted. 2 and 3, the end cap 30 provided on the other side in the longitudinal direction of the ventilation member 100 is shown separated from the longitudinal end surface of the ventilation member 100 for convenience of explanation. The end caps 30 are provided at both longitudinal ends of the ventilation member.

The end caps 30 are provided so as to cover both longitudinal end surfaces of the ventilation member 100 . The end cap 30 has locking projections 31 that can be locked into locking holes H formed between the joined portion 12 f of the inner member 10 and the joint portion 23 f of the outer member 20 .
As described above, the end cap 30 has the locking protrusion 31 that can be locked into the locking hole H formed between the jointed portion 12f of the inner member 10 and the joint portion 23f of the outer member 20. , the joint structure of the inner member 10 and the outer member 20 can be used to easily attach to the ventilation member 100 .

The locking projection 31 may be provided at the center 30P of the end cap 30 in the inside-outside direction. 1 to 3, the locking hole H is formed in the outer member 20 at a distance D corresponding to the distance from the outer end 30e of the end cap 30 to the center 30P of the end cap 30 in the inside-outside direction. It may be provided at a position away from the outer end 20e. As a result, the end caps 30 can be made symmetrical in the inside-outside direction, so that one end cap 30 and the other end cap 30 of the ventilation member 100 can be a common component with the same structure. In addition, the end caps 30 can cover the end faces of the ventilation member 100 even if the end caps 30 are provided on either end face of the ventilation member 100 .
