Description

  The present invention relates to a waterproof structure for an upper part of an outer wall and a waterproof unit, and particularly in a building having a gap between a plate-like member (for example, a nasal cover member) extending along an end of a roof and an upper part of an outer wall surface material. The present invention relates to a waterproof structure at an upper portion of an outer wall and a waterproof unit used in such a building.

  In a building such as a house, outside air is taken in from the eaves and the eaves to ventilate the attic space. When taking outside air from the eaves, as shown in Japanese Patent Application Laid-Open No. 2001-349023 (Patent Document 1), caulking is applied to the joint portion (that is, the eaves) between the eaves member such as an eaves board and the outer wall. ing.

  On the other hand, when taking in the outside air from the eaves, a parting material having a vent is provided at the joint between the eaves member and the outer wall. For example, in Japanese Patent Application Laid-Open No. 2009-102806 (Patent Document 2), in a building that does not have an eaves ceiling board, a cross-sectional groove type having ventilation holes so as to close an eaves ceiling space between an outer wall and a nasal cover. A parting edge panel is arranged. The parting edge panel is in contact with both the upper end surface of the outer wall and the back surface of the nose cover decorative plate.

  In addition, a water return material may be provided so that rainwater that enters the eaves space from the eaves vents does not enter the eaves space. For example, in Japanese Patent Application Laid-Open No. 2008-156897 (Patent Document 3), the water return material is disposed on the upper portion of the outer wall so as to protrude outward from the outer wall surface material. This water return material is fixed to the upper part of the outer wall by boltlessness by being sandwiched between water return fixing clips fitted between adjacent trunk edges.

The nasal concealment member 23 includes at least a nasal concealment base 231. The nasal concealment member 23 may further include an incombustible material 232 that is fixed to the outdoor surface (the outdoor side surface) of the nasal concealment base 231. The nasal concealment member 23 (nasal concealment base 231) extends in the spar direction in contact with the lower side of the eaves end side end surface 22 a of the plurality of rafters 22. In the present embodiment, a ventilation opening 20 is provided between the upper end surface 23c of the nasal concealment member 23 and the lower surface of the roof 21 (that is, the eaves side) for shed ventilation.

  The nasal cover member 24 is made of, for example, steel and is a decorative cover member that covers at least the surface 23 a of the nasal cover member 23. In the present embodiment, the nasal cover member 24 includes a vertical surface portion 241 disposed along the surface 23 a of the nasal cover member 23, and extends indoors from the lower end of the vertical surface portion 241, and the lower end surface 23 d of the nasal cover member 23.

The rising portion 243 is disposed at the position of the back surface 23b of the nose masking member 23 in the depth direction. The nose cover cover member 24 may further include an inclined portion 242 to which the ventilation member 25 is attached. The inclined portion 242 extends obliquely downward from the upper end portion of the vertical surface portion 241 to the outdoor side.

  As shown in FIGS. 1 and 2, in the present embodiment, a gap 70 is formed between the nose mask member 23 and the upper portion of the outer wall surface material 11 (outer wall portion 10). The depth dimension of the gap 70 is 5 mm or more, for example, 9 mm. The 1st draining member 3 and the 2nd draining member 5 are arrange | positioned in order to prevent that rainwater permeates into the cabin space from this gap 70.

  With reference to FIG. 2 and FIG. 3, the structural example of the 1st draining member 3 is demonstrated. FIG. 3 is a perspective view showing the first draining member 3. The first draining member 3 closes the gap 70 above. The first draining member 3 includes an upper shielding part 31, an upper contact part 32, and an edge part 33. The upper shielding part 31 extends to the back surface 23 b of the nose masking member 23 along the upper end surface 11 c of the outer wall surface material 11. The upper contact portion 32 is connected to the outdoor side end portion of the upper shielding portion 31 and extends in the vertical direction.

  The upper shielding part 31 is preferably arranged so as to cover the upper end surface 11c of the outer wall surface material 11, and in the present embodiment, covers the entire upper end surface 11c from one end to the other end in the depth direction. In addition, the preferable example of a shape of the upper side shielding part 31 in case the outer wall surface material 11 has the some cavity 15 penetrated to an up-down direction is mentioned later.

  The outdoor surface (surface on the outdoor side) of the upper contact portion 32 is in surface contact with the back surface 23 b of the nose mask member 23. As shown in FIG. 2, the upper abutting portion 32 may abut on the back surface 23 b of the nasal concealment member 23 via an elastic dry sealing material 34. In this case, the upper contact portion 32 may be formed as a leaf spring. It is desirable that the dry sealing material 34 is fixed to the outdoor surface of the upper contact portion 32 in advance.

  The edge portion 33 rises upward from the indoor side end portion of the upper shielding portion 31. As will be described later, the edge portion 33 is used for fixing the first draining member 3 by the fixing member 4.

  The upper shielding part 31 (main body), the upper contact part 32 and the edge part 33 of the first draining member 3 are formed, for example, by bending a single steel plate. Moreover, when the 1st draining member 3 is formed in piece shape, the 1st draining member 3 of several pieces is a clearance gap along the longitudinal direction (girder direction) of the upper end surface 11c of the outer wall surface material 11. Arranged without.

  With reference to FIG. 2, the structural example of the 2nd draining member 5 is demonstrated. The second draining member 5 closes the lower part of the gap 70. The second draining member 5 includes a lower shielding part 51 and a lower contact part 52. The lower shielding part 51 extends to the surface 11 a of the outer wall surface material 11 along the lower end surface 23 d of the nose masking member 23. The lower contact portion 52 is connected to the indoor side end portion of the lower shielding portion 51 and extends in the vertical direction. The indoor surface (indoor side surface) of the lower contact portion 52 is in surface contact with the surface 11 a of the outer wall surface material 11.

  In the present embodiment, the second draining member 5 has a substantially U-shaped cross section. Therefore, the lower shielding part 51 includes first and second shielding parts 511 and 512 that extend to the outer wall surface member 11 along the lower end surface 23 d of the nose masking member 23. The first shielding part 511 contacts the lower end surface 23 d of the nose masking member 23 and is connected to the upper end part of the lower contact part 52. The second shielding part 512 is located below the first shielding part 511 and is connected to the lower end part of the lower contact part 52. In addition, the 1st shielding part 511 and the 2nd shielding part 512 do not need to be parallel.

  In the present embodiment, the second draining member 5 is fixed below the nose cover member 23 by the connecting tool 80 such as a screw passing through the first shielding part 511. In this case, the length in the depth direction of the second shielding part 512 may be shorter than that of the first shielding part 511 in order to facilitate driving of the connector 80.

  The outdoor side end portion of the second draining member 5 is covered with the above-mentioned nose cover member 24. In this case, it is desirable that the second shielding portion 512 is in contact with the upper end portion of the rising portion 243 of the nasal concealing cover material 24.

  The lower shielding part 51 and the lower contact part 52 of the second draining member 5 are also formed by bending a single steel plate, for example. Moreover, when the 2nd draining member 5 is formed in piece shape, the 2nd draining member 5 of several pieces is a clearance gap along the longitudinal direction (girder direction) of the lower end surface 23d of the nose masking member 23. Arranged without.

  The fixing member 4 is fitted into the ventilation layer 12 of the outer wall portion 10 and fixes the first draining member 3 to the upper portion of the outer wall. The fixing structure of the first draining member 3 using the fixing member 4 will be described in detail later.

  Here, an example of a preferable shape of the upper shielding portion 31 of the first draining member 3 in the case where the outer wall surface material 11 has a plurality of cavities 15 will be described with further reference to FIG. FIG. 4 is a cross-sectional view showing a shape example of the first draining member 3. In FIG. 4, the outer wall surface material 11 is indicated by an imaginary line.

  When the thickness of the outer wall surface material 11 is large (for example, 25 mm or more), a plurality of cavities (hollow layers) 15 penetrating in the vertical direction are generated in the manufacturing process. In this case, on the upper end surface 11c of the outer wall surface material 11, as shown in FIG. 7, an opening 15a (hereinafter referred to as “small edge”) 15a of the cavity 15 is formed so as to be arranged in a line at a substantially central position in the depth direction. The In the case of such an outer wall surface material 11, when water is applied to the upper end surface 11 c, the water enters the cavity 15 from the small opening 15 a. Then, it leads to freezing and deterioration of the outer wall surface material 11. Further, when the (first) draining member is placed so as to completely cover the entire upper end surface 11c of the outer wall surface material 11, moisture in the cavity 15 cannot be released to the outside from the small opening 15a.

  Therefore, the upper shielding part 31 of the first draining member 3 of the present embodiment has an upper end contact part 311 and an upper end non-contact part 312 as shown in FIG. The upper end contact portion 311 contacts the outdoor side upper end portion of the outer wall surface material 11. The upper end non-contact portion 312 is arranged in a state of being floated from the upper end surface 11 c of the outer wall surface material 11 on the indoor side from the upper end contact portion 311.

  Specifically, a dry-type sealing material is provided on the back surface of the upper shielding portion 31 only on the outdoor side of the substantially central position of the portion (hereinafter referred to as “facing portion”) 310 facing the upper end surface 11c of the outer wall surface material 11. 35 is affixed. In this case, the dry seal material 35 attached to the facing portion 310 constitutes the upper end contact portion 311, and the portion of the facing portion 310 without the dry seal material 35 constitutes the upper end non-contact portion 312. The dry sealing material 35 is made of a compressible elastic body, and the material thereof is, for example, foam rubber. As the dry sealing material 35, for example, EPT SEALER (registered trademark) manufactured by Nitto Denko Corporation may be used. The dry sealing material 34 described above may also be the same material as the dry sealing material 35.

  Thus, by providing the dry sealing material 35 on a part of the lower surface of the upper shielding part 31, the upper shielding part 31 is formed to have a step within the thickness range of the outer wall surface material 11. It is desirable that the boundary of this step is located on the row of the small openings 15a appearing on the upper end surface 11c of the outer wall surface material 11. In other words, the upper shielding portion 31 prevents all the small openings 15 a of the cavity 15 from being blocked by the dry sealing material 35. Therefore, moisture in the cavity 15 can be appropriately released to the outside.

  The step boundary position is such that the space 60 between the upper end surface 11c of the outer wall surface material 11 and the upper shielding part 31 of the first draining member 3 and at least a part of the cavity 15 are in communication. As long as it is selected. For example, the dry sealing material 35 may not be covered at all on the small opening 15 a of the cavity 15.

  In the present embodiment, the dry sealing material 35 is also provided on the portion of the upper shielding portion 31 other than the facing portion 310, that is, on the lower surface of the portion facing the gap 70. The dry sealing material 35 may not be provided.

  As described above, the upper shielding portion 31 of the first draining member 3 extends from the indoor side toward the outdoor side so as to contact the back surface 23b of the nose-hidden member 23, and the lower shielding member 5 of the second draining member 5 is shielded. The part 51 extends toward the indoor side so as to come into contact with the surface 11a of the outer wall surface material 11 from the outdoor side. Therefore, the upper and lower sides of the gap 70 between the nasal concealing member 23 and the outer wall surface member 11 are closed from different directions by a set of waterproof units including the first draining member 3 and the second draining member 5. Can be removed. Therefore, even if rainwater enters into the gap 70 from between the second draining member 5 and the surface 11a of the outer wall surface material 11, the rainwater hits the upper shielding portion 31 of the first draining member 3, Rainwater can be prevented from entering the cabin space. Moreover, since the 2nd draining member 5 is arrange | positioned under the clearance gap 70, the beauty | look of a building can be maintained or improved.

  Further, in the present embodiment, the dry sealing material 35 provided on the facing portion 310 of the upper shielding portion 31 of the first draining member 3 contacts the outdoor side end portion of the upper end surface 11 c of the outer wall surface material 11. It touches. Therefore, it is possible to prevent rainwater that has entered the gap 70 from being applied to the upper end surface 11 c of the outer wall surface material 11.

  Further, when the outer wall surface material 11 is a so-called thick outer wall, at least a part of the small edge 15a of the upper end surface 11c is open (communication with the space 60). Therefore, even if the first draining member 3 is disposed so as to cover the upper end surface 11 c of the outer wall surface material 11, it is possible to ensure the function of discharging moisture from the small opening 15 a of the upper end surface 11 c of the outer wall surface material 11. As a result, freezing and deterioration of the outer wall portion 10 including the outer wall surface material 11 can be prevented.

  In addition, you may apply the 1st draining member 3 of the said shape also to the outer wall of the general thickness without the cavity 15. FIG. Even if the outer wall has such a general thickness, the first draining member 3 having a step in the depth direction is provided on the upper portion thereof, so that rainwater is absorbed from bubbles or the like of the upper end surface 11c. Can be prevented.

  In the unlikely event that rainwater enters the first draining member 3 due to deterioration of the dry sealing material 34 sandwiched between the upper contact portion 32 of the first draining member 3 and the back surface 23b of the nose cover member 23, etc. Even in such a case, rainwater can be returned at the edge 33. Therefore, it is also possible to prevent intrusion water from dripping onto the upper end surface 11 c of the outer wall surface material 11 from the indoor side end portion of the first draining member 3 through the space 60.

(First draining member fixing structure)
Next, the fixing structure of the first draining member 3 using the fixing member 4 will be described. First, an example of the structure of the fixing member 4 will be described with reference to FIGS. FIG. 5 is a perspective view showing the fixing member 4.

  The fixing member 4 includes a fitting part 41, a pressing part 42, and a locking part 43. The fitting portion 41 is fitted into the ventilation layer 12. The fitting portion 41 is inclined more than the abutting portion 411 that abuts against the back surface 11 b of the outer wall surface material 11, the lower end connecting portion 412 connected to the lower end of the abutting portion 411, and the indoor side end of the lower end connecting portion 412. And a leaf spring portion 413 extending upward. The abutting portion 411 is provided with a claw 414 for preventing removal after fitting. The leaf spring part 413 is biased in a direction away from the contact part 411. The fixing member 4 further includes an upper lid portion 44 extending from the upper end portion of the leaf spring portion 413 to the outdoor side.

  The pressing part 42 fixes the first draining member 3 to the upper end surface 11 c of the outer wall surface material 11 by pressing the upper part of the upper shielding part 31 of the first draining member 3 from above. The locking portion 43 is provided between the upper end portion of the contact portion 411 of the fitting portion 41 and the indoor side end portion of the pressing portion 42, and locks or holds the edge portion 33 of the first draining member 3. To do. The locking portion 43 has, for example, an inverted V-shaped groove.

  The installation method of the 1st draining member 3 using the fixing member 4 is demonstrated concretely using FIG. 6 and FIG. FIG. 6 is a diagram showing an assembly procedure of the first draining member 3 and the fixing member 4 according to the embodiment of the present invention. FIG. 7 is a perspective view showing an installation procedure of the first draining member 3 according to the embodiment of the present invention.

  First, referring to FIGS. 6A, 6 </ b> B, and 6 </ b> C, the edge 33 of the first draining member 3 is fitted into the groove of the locking portion 43 of the fixing member 4. Thereby, the first draining member 3 is locked or held by the fixing member 4. As shown in FIG. 7, a plurality of fixing members 4 are attached to one first draining member 3. In this state, the fitting portion 41 of the fixing member 4 is fitted into the ventilation layer 12. Specifically, the fixing member 4 is press-fitted between the trunk edges 16 arranged at intervals in the ventilation layer 12. Thereby, the contact part 411 of the fitting part 41 is press-contacted to the back surface 11b of the outer wall surface material 11, and the leaf | plate spring part 413 is press-contacted to the heat insulating material 13. FIG. The fixing member 4 is press-fitted until the bottom surface of the first draining member 3 (that is, the lower surface of the dry sealing material 35) is brought into contact with the upper end surface 11c of the outer wall surface material 11. When the fixing member 4 is sufficiently pushed in, the first draining member 3 is pressed from above by the pressing portion 42. Thereby, since the dry sealing material 35 below the first draining member 3 is compressed downward, water is stopped between the dry sealing material 35 and the upper end surface 11c of the outer wall surface material 11 without a gap.

  Further, when the fixing member 4 is sufficiently pushed in, the fixing member 4 is securely fixed to the ventilation layer 12 by the restoring force of the leaf spring portion 413. Moreover, since the nail | claw 414 which protrudes diagonally upward toward the outer wall surface material 11 side is formed in the contact part 411, the drop-out | falling upward is also prevented. FIG. 6C shows the shape of the fixing member 4 in a state where the first draining member 3 is attached to the upper end of the outer wall surface material 11 as shown in FIG.

  As described above, by using the fixing member 4, the first draining member 3 can be fixed to the upper portion of the outer wall portion 10 without bolts. The fixing member 4 may also be included in the waterproof unit.

(Modification of the first draining member)
The shape of the first draining member 3 is not limited to the above example. For example, it may be shaped like a first draining member 3A as shown in FIG. 8 or a first draining member 3B as shown in FIG.

  The first draining member 3A shown in FIG. 8 does not include the dry sealing material 35, and the upper shielding part 31 body forms a step. That is, the upper end contact portion 311 of the first draining member 3A is formed by a part of the facing portion 310 of the upper shielding portion 31 main body. In this case, the upper shielding portion 31 further includes a connecting portion 313 that connects the upper end contact portion 311 and the upper end non-contact portion 312 and extends in the vertical direction.

  The first draining member 3 </ b> B shown in FIG. 9 does not form a step within the thickness range of the outer wall surface material 11. The upper shielding part 31 of the first draining member 3B extends obliquely upward from the outdoor side end part to the indoor side end part. In this case, the upper end contact portion 311 of the first draining member 3B does not contact the upper end surface 11c of the outer wall surface material 11, but contacts the upper end corner portion on the outdoor side of the outer wall surface material 11 or the vicinity thereof. Yes. Thus, the upper end contact portion 311 only needs to be in contact with the outdoor side upper end portion of the outer wall surface material 11.

  In this case, when the fixing member 4 holding the first draining member 3 </ b> B is press-fitted into the ventilation layer 12, the upper end non-contact portion 311 is arranged along the longitudinal direction so that the upper end contact portion 311 does not float. For example, it is desirable to provide a plurality of legs (not shown). The first draining member 3A shown in FIG. 8 or the first draining member 3 shown in FIG. 4 is also placed on the upper end surface 11c of the outer wall surface material 11 on the upper end non-contact portion 312. A plurality of legs or the like may be provided.

  In addition, when the upper end surface 11c of the outer wall surface material 11 does not have the small opening 15a or the bubble, the facing portion 310 of the upper shielding portion 31 may not include the upper end non-contact portion 312. That is, the entire facing portion 310 may abut against the entire upper end surface 11 c of the outer wall surface material 11.

  Further, the first draining member 3 (3A, 3B) may include only the upper shielding part 31 without including the upper contact part 32 and the edge part 33.

(Modification of the second draining member)
The shape of the second draining member 5 is not limited to the above example. For example, it may be shaped like a second draining member 5A as shown in FIG. 10 or a second draining member 5B as shown in FIG.

  The second draining member 5A shown in FIG. 10 has a substantially L-shaped cross section. That is, the lower shielding part 51 and the lower contact part 52 of the second draining member 5A are the same as the upper shielding part 31 (main body) and the upper contact part 32 of the first draining member 3 shown in FIG. You may have the shape of. In this case, it is desirable that the lower shielding portion 51 of the second draining member 5 </ b> A is fixed in a state of being in contact with the lower end surface 23 d of the nose masking member 23. The lower shielding part 51 is connected to the lower end part of the lower contact part 52, for example.

  In this case, similarly to the upper contact portion 32 of the first draining member 3, the lower contact portion 52 of the second draining member 5A is also formed as a leaf spring, and its indoor surface (outdoor side surface). In addition, an elastic dry sealing material 53 may be adhered.

  The second draining member 5B shown in FIG. 11 is formed integrally with the nasal cover member 24A. The nose cover member 24A does not include, for example, the lower edge portion 242 and the rising portion 243 shown in FIG. 2, and the lower end portion of the vertical surface portion 241 has the outdoor side end of the lower shielding portion 51 of the second draining member 5B. The parts are connected. That is, the lower shielding part 51 of the second draining member 5B is disposed so as to cover the entire lower end surface 23d of the nose masking member 23. In this case, the lower shielding portion 51 may not be in contact with the lower end surface 23 d of the nose masking member 23.

  The second draining member 5B may be fixed below the nose cover member 23 without using a connector 80 such as a screw. The nasal concealment cover member 24A is fixed to the nasal concealment member 23 by, for example, passing a connector such as a screw through the vertical surface portion 241.

  Further, the second draining member 5 (5A, 5B) may also include only the lower shielding part 51 without including the lower contact part 52.

  In addition, although the waterproof structure of the outer wall upper part which concerns on the said embodiment demonstrated the eaves part of the building as an example, it can be applied also to the keraba part of a building. In this case, the “plate member” is a windbreak plate that extends in the gradient direction along the end of the roof 21. In this case, the ventilation opening for ventilation in the back of the hut may be provided between the nasal cover member or the eaves board and the outer wall surface material, that is, on the eaves side.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
