This application is based on Japanese Patent Application No. 2015-049037 filed with the Japanese Patent Office on Mar. 12, 2015, the entire content of which is hereby incorporated by reference.
The present invention relates to a waterproofing member and an exterior wall structure using the same.
For example, opening members such as a window sash and a door, as well as exterior wall materials and the like formed of a ceramic material such as cement are mounted to a building such as a house. In such a building, an opening is defined by a frame member such as a column member in a location where a window, an entrance, or the like is disposed, and this opening provides communication between the exterior side and the interior side. A wall backing member such as a furring strip is mounted to the frame member. As a result of mounting an exterior wall material to the building, the wall backing member is located between the frame member and the interior side of the exterior wall material.
The opening member includes an opening member body. The opening member body is disposed within the opening as a result of mounting the opening member to the frame member. Consequently, the opening member body enables opening and closing of the opening, in other words, a window, an entrance, or the like.
The exterior wall material is mounted to the wall backing member around the opening member, while the exterior wall materials are positioned in a state in which it is spaced apart from the opening member body at a certain interval. To mount the exterior wall material to the wall backing member in this manner, a securing member as disclosed in JP 2009-41181A may be used, for example. The securing member is provided with a securing portion capable of engaging the exterior wall material. The securing member is fixed to the wall backing member by being screwed to the wall backing member. A plurality of securing members are fixed to the wall backing member in this way, and the exterior wall material is secured to the securing portions, and thereby, the exterior wall material is mounted to the wall backing member while the exterior wall materials are positioned in the manner described above.
For such a building, waterproofing of the building is performed between the opening member and the exterior wall material in order to prevent the entry of rainwater or the like into the interior side. In general, such waterproofing is performed by filling between the opening member body and the exterior wall material with a caulking compound or the like after the exterior wall material has been mounted to the wall backing member (See JP 2009-41181A).
However, to perform accurate positioning of the exterior wall material by using the above-described conventional securing members, a high precision is required for the positions of the securing members relative to each other when the securing members are mounted to the wall backing member. At this time, separately mounting each of the securing members to the wall backing member tends to cause variations between the positions of the securing member relative to each other. To suppress such variations, each of the securing members needs to be carefully positioned and mounted to the wall backing member. Consequently, the above-described securing members and the exterior wall structure using the same increase the complexity of the operation of mounting the securing members and the exterior wall material to the wall backing member while positioning these components. Accordingly, installation requires a skilled technician and consumes a large amount of time, resulting in an increase in the cost required for the installation.
To waterproof the building, when filling between the opening member body and the exterior wall material with a caulking compound or the like after the exterior wall material has been mounted to the wall backing member, the number of steps required for the installation increases accordingly. Furthermore, the waterproofing capability tends to vary among locations filled with the caulking compound or the like. Accordingly, in waterproofing the building, the installation becomes complex, and a large amount of working time is needed.
The present invention has been made in view of the above-described conventional circumstances, and it is an object of the invention to provide a waterproofing member and an exterior wall structure that accurately position the exterior wall material, ensure the waterproofness of the building to which the opening member and the exterior wall material are mounted, and achieve easy installation.
In a waterproofing member for performing waterproofing of a building according to an aspect of the present invention, the building includes:
a frame member defining an opening that provides communication between an exterior side and an interior side;
an exterior wall material configured to be mounted on the exterior side of the frame member;
a wall backing member that is mounted to the frame member, and is located between the frame member and the exterior wall material; and
an opening member including an opening member body disposed in the opening.
The waterproofing member includes:
a fixing portion configured to be fixed to at least one of the wall backing member and the frame member at a time of installation when the waterproofing member is installed between the wall backing member and the exterior wall material;
a positioning portion joined to the fixing portion, and extending toward the exterior side so as to face an end face of the exterior wall material at the time of the installation;
a separating portion joined to the positioning portion, and extending toward the opening member body side so as to be located between the opening member body and the exterior wall material at the time of the installation;
a supporting portion joined to the separating portion, and facing the opening member body at the time of the installation;
a first seal portion provided on at least one of the fixing portion and the positioning portion, and coming into abutment with the exterior wall material at the time of the installation; and
a second seal portion provided on the supporting portion, and coming into abutment with the opening member body at the time of the installation.
With the waterproofing member according to the present invention, it is possible to accurately position the exterior wall material, ensure the waterproofness of the building to which the opening member and the exterior wall material are mounted, and achieve easy installation. According to an exterior wall structure using the waterproofing member according to the present invention, it is possible to accurately position the exterior wall material, ensure the waterproofness of the building to which the opening member and the exterior wall material are mounted, and achieve easy installation.
A waterproofing member according to an aspect of the present invention is a waterproofing member that is provided in a building to which an opening member and an exterior wall material are mounted, and waterproofs the building between the opening member and the exterior wall material.
The building includes a frame member defining an opening that provides communication between an exterior side and an interior side, and a wall backing member that is mounted to the frame member and is located between the frame member and the interior side of the exterior wall material,
wherein the opening member includes an opening member body disposed within the opening.
The waterproofing member includes: a fixing portion that is fixed to the wall backing member and is located between the wall backing member and the exterior wall material;
a positioning portion that extends continuously with the fixing portion toward the exterior side, and positions the exterior wall material by coming into abutment with an end face of the exterior wall material;
a separating portion that extends continuously with the positioning portion toward the opening member body side, and is located between the opening member body and the exterior wall material;
a supporting portion that is continuous with the separating portion and faces the opening member body;
a first seal portion that is provided on the fixing portion or the positioning portion to inhibit the entry of water by coming into abutment with the exterior wall material; and
a second seal portion that is provided on the supporting portion to inhibit the entry of the water by coming into abutment with the opening member body.
With the waterproofing member according to the present aspect, the fixing portion is fixed to the wall backing member in a state in which the second seal portion is brought into abutment with the opening member body. This enables positioning when the waterproofing member is fixed to the wall backing member. Then, in a state in which the waterproofing member is fixed to the wall backing member, an end face of the exterior wall material is brought into abutment with the positioning portion of the waterproofing member. Thereby, with this waterproofing member, it is possible to position the exterior wall material with the positioning portion, while defining the interval between the opening member body and the exterior wall material by the separating portion. Accordingly, with the waterproofing member, it is possible to position the exterior wall material easily and accurately, without requiring a skilled technician. Note that the exterior wall material that has been positioned by the waterproofing member in this manner is fixed to the wall backing member, for example, by means of a fastener such as a nail.
Also, with this waterproofing member, the first seal portion is provided on the fixing portion, and the second seal portion is provided on the supporting portion. Thus, with the waterproofing member, by simply fixing the fixing portion to the wall backing member and bringing the end face of the exterior wall material into abutment with the positioning portion in the above-described manner, it is possible to prevent the entry of water from between the waterproofing member and the exterior wall material with the first seal portion, and prevent the entry of water from between the waterproofing member and the opening member body with the second seal portion. Accordingly, with the waterproofing member, it is possible to omit filling a caulking compound or the like between the opening member body and the exterior wall material to waterproof the building, or reduce the number of filling locations even when partially filling a caulking compound or the like. Due to a reduced number of locations filled with a caulking compound or the like, it is also possible to suppress variations in the waterproofing capability among the locations filled with the caulking compound or the like. Consequently, with the waterproofing member, it is possible to easily waterproof the building.
Accordingly, with the waterproofing member according to the present aspect, it is possible to accurately position the exterior wall material, ensure the waterproofness of the building to which the opening member and the exterior wall material are mounted, and achieve easy installation.
Preferably, the separating portion is located on the interior side with respect to the outer surface of the exterior wall material. In this case, the separating portion does not protrude to the exterior side with respect to the exterior wall material, and therefore, the separating portion is less noticeable between the opening member body and the end face of the exterior wall material when the building is viewed from the exterior side. This enhances the aesthetic appearance of the building.
Preferably, the separating portion is formed flat. In this case, no projection or the like is formed on the separating portion, and therefore, the waterproofing member is formed easily. When a facing member that covers between the opening member body and the end face of the exterior wall material is mounted to the separating portion, the mounting of the facing member is facilitated. Furthermore, since the separating portion is flat, it is possible to enhance the aesthetic appearance of the building even without the above-described facing member mounted to the separating portion.
An exterior wall structure according the present aspect is an exterior wall structure for waterproofing a building between an opening member and an exterior wall material that are mounted to the building, by using a waterproofing member provided in the building.
The building includes a frame member defining an opening that provides communication between an exterior side and an interior side, and a wall backing member that is mounted to the frame member and is located between the frame member and the interior side of the exterior wall material,
wherein the opening member includes an, opening member body disposed within the opening.
The waterproofing member includes: a fixing portion that is fixed to the wall backing member and is located between the wall backing member and the exterior wall material;
a positioning portion that extends continuously with the fixing portion toward the exterior side, and positions the exterior wall material by coming into abutment with an end face of the exterior wall material;
a separating portion that extends continuously with the positioning portion toward the opening member body side, and is located between the opening member body and the exterior wall material;
a supporting portion that is continuous with the separating portion and faces the opening member body;
a first seal portion that is provided on the fixing portion or the positioning portion to inhibit the entry of water by coming into abutment with the exterior wall material; and
a second seal portion that is provided on the supporting portion to inhibit the entry of the water by coming into abutment with the opening member body.
For the exterior wall structure according to the present aspect, a waterproofing member having the above-described features is used. With this exterior wall structure, it is possible to position the exterior wall material easily and accurately. With this exterior wall structure, it is also possible to omit filling a caulking compound or the like between the opening member body and the exterior wall material to waterproof the building, or to reduce the number of filling locations even when partially filling a caulking compound or the like. Thereby, with this exterior wall structure, it is also possible to easily waterproof the building.
Accordingly, with the exterior wall structure according to the present aspect, it is possible to accurately position the exterior wall material, ensure the waterproofness of the building to which the opening member and the exterior wall material are mounted, and achieve easy installation.
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
An exterior wall structure according to the embodiment is used for a building 1 as a house shown in
As shown in
The building 1 is a wooden building, and includes frame members 13 shown in
The building 1 is constructed by assembling the frame members 13, the vertical furring strips 15a, the horizontal furring strips 15b and the like by a known construction technique. Note that a plurality of the frame members 13 are provided, and only one of the frame members 13 is shown in
In the building 1, the plurality of frame members 13 are assembled into a frame, thus defining a rectangular opening 19 as shown in
The window sash 3 shown in
As shown in
This exterior wall structure is installed by performing the following steps.
First, an opening member mounting step is performed in which the window sash 3 is mounted to the building 1. Specifically, the flange 3b is brought into abutment with the exterior side of the frame member 13, with the sash body 3a disposed within the opening 19. In this state, a nail 21 is inserted into each of the mounting holes 133, and the nails 21 are driven into the frame member 13 from the exterior side, thus fixing the flange 3b on the exterior side of the frame member 13. Here, as described above, each of the mounting holes 133 is formed at a position nearer to the sash body 3a than the distal end portion 134 of the flange 3b. Accordingly, the flange 3b is fixed on the exterior side of the frame member 13 at a position nearer to the sash body 3a than the distal end portion 134. After the flange 3b has been fixed to the frame member 13, a waterproof tape 23 is attached to the frame member 13. Additionally, the above-described waterproof sheet 17 is installed on the exterior side of the waterproof tape 23. Due to the above, waterproof treatment between the frame member 13 and the flange 3b is provided. Note that the flange 3b is fixed to the frame member 13 by means other than the nails 21, such as screws or the like.
Although not shown, a plurality of mounting holes are formed in the sash body 3a, and the sash body 3a is fixed to the frame member 13 also by means of mounting screws inserted through these mounting holes. To mount the window sash 3 to the building 1, a spacer member 25 is optionally provided as appropriate between the frame member 13 and the sash body 3a. In this way, the window sash 3 is provided in the building 1, thus completing the opening member mounting step.
Next, a waterproofing member mounting step is performed in which each of the first to fourth waterproofing members. 7 to 10 shown in
As shown in
The waterstop body 29 is formed of a metal plate extending from one end side to the other end side in the width direction and also extending in the longitudinal direction, and has an exterior face 290a and an interior face 290b as shown in
As shown in
As shown in
The separating portion 29c is bent at a substantially right angle toward the other end side of the waterstop body 29 from the end portion on the exterior side of the positioning portion 29b, and thereby extends in the width direction toward the other end side of the waterstop body 29 while being continuous with the positioning portion 29b. That is, as shown in
As shown in
The supporting portion 29d is bent at a substantially right angle toward the interior side from the end portion on the other end side of the separating portion 29c, and thereby extends toward the interior side while being continuous with the separating portion 29c. Note that the supporting portion 29d is alternatively formed by being bent toward the exterior side from the end portion on the other end side of the separating portion 29c
The first seal portion 31 and the second seal portion 33 are formed of an ethylene-propylene rubber (EPDM) having a rectangular shape. Note that the first seal portion 31 and the second seal portion 33 are not necessarily formed of EPDM, and are formed of a synthetic rubber or various materials capable of inhibiting the entry of water. In addition, the first seal portion 31 and the second seal portion 33 are formed of mutually different materials.
The length of the first and second seal portions 31 and 33 in the longitudinal direction is defined according to the length of the waterstop body 29 in the longitudinal direction. The first seal portion 31 is attached to the exterior face 290a of the fixing portion 29a. The first seal portion 31 is in contact with the positioning portion 29b, but is not bonded thereto. Consequently, the first seal portion 31 is located at a corner portion formed by the fixing portion 29a and the positioning portion 29b so as to be in contact with the fixing portion 29a and the positioning portion 29b.
When the first seal portion 31 is not bonded onto the positioning portion 29b as in this case, the lower end face of the exterior wall material 5 is positioned by being brought into direct contact with the flat positioning portion 29b while the first seal portion 31 is being compressed as shown in
However, in cases such as when positioning is not required to be accurate for the exterior wall material 5, it is possible to adopt a configuration in which the first seal portion 31 is bonded onto the positioning portion 29b.
The second seal portion 33 is provided on the supporting portion 29d by being attached to the supporting portion 29d. The second seal portion 33 is formed to be thinner than the first seal portion 31. Note that the second seal portion 33 is optionally formed to have the same thickness as that of the first seal portion 31, or is optionally formed to be thicker than the first seal portion 31.
To mount the first waterproofing member 7 to the building 1, first, the first waterproofing member 7 is disposed above the sash body 3a as shown in
Here, as described above, each of the mounting holes 290c is formed in the fixing portion 29a such that the distance from the outer surface 132 of the sash body 3a is farther than the distance from the end portion of the flange 3b. Accordingly, the fixing portion 29a is fixed to the horizontal furring strip 15b by the first mounting screws 35 at positions spaced farther away from the outer surface 132 than the end portion of the flange 3b, or in other words, at positions where the flange 3b is not present. Consequently, in this exterior wall structure, the distal ends of the first mounting screws 35 contact with neither the flange 3b, nor the waterproof tape 23 when the fixing portion 29a is fixed to the horizontal furring strip 15b.
By following the same procedure, the second waterproofing member 8 is fixed to the horizontal furring strip 15b below the sash body 3a as shown in
After completion of the waterproofing member mounting step, a caulking compound filling step for filling with a caulking compound 37 is performed. Specifically, the caulking compound 37 fills each of the gaps between the first waterproofing member 7 and the third waterproofing member 9, the gap between the third waterproofing member 9 and the second waterproofing member. 8, the gap between the second waterproofing member 8 and the fourth waterproofing member 10, and the gap between the fourth waterproofing member 10 and the first waterproofing member 7. Additionally, the caulking compound 37 also fills each of the gaps between the first and third waterproofing members 7 and 9 and the upper right corner portion of the sash body 3a, the gap between the second and third waterproofing members 8 and 9 and the lower right corner portion of the sash body 3a, the gap between the second and fourth waterproofing members 8 and 10 and the lower left corner portion of the sash body 3a, and the gap between the first and fourth waterproofing members 7 and 10 and the upper left corner portion of the sash body 3a. Furthermore, the caulking compound 37 also fills the upper end and the lower end of each of the third and fourth waterproofing members 9 and 10. Due to the above, the gap between the first waterproofing member 7 and the third waterproofing member 9, and the like are each closed with the caulking compound 37, thus preventing rainwater or the like from flowing into the interior side through the gap between the first waterproofing member 7 and the third waterproofing member 9, and the like.
Here, for example, the gap between the first waterproofing member 7 and the third waterproofing member 9 is closed not only by the caulking compound 37, but also by the second seal portion 33 of the third waterproofing member 9. The other gaps; including for example, the gap between the third waterproofing member 9 and the second waterproofing member 8, are also closed by the second seal portion 33 in the same manner. Consequently, with this exterior wall structure, it is possible, also by the second seal portion 33, to prevent rainwater or the like from flowing into the interior side through the gap between the first waterproofing member 7 and the third waterproofing member 9, and the like. Accordingly, although the entry of rainwater or the like into the interior side, for example, from the gap between the first waterproofing member 7 and the third waterproofing member 9 is fully prevented by filling with the caulking compound 37, the caulking compound filling step is not essential for this exterior wall structure, and is omissible. It is also possible to omit some of the locations filled with the caulking compound 37 during the caulking compound filling step.
Next, an exterior wall material mounting step is performed in which a plurality of exterior wall materials 5 are mounted to the building 1. Each of the exterior wall materials 5 is formed of a ceramic material. As such an exterior wall material 5, it is possible to use, for example, “MOEN EXCELARD (Japanese registered trademark)” manufactured by “NICHIHA CORPORATION”. As shown in
To mount the exterior wall material 5 to the building 1 above the sash body 3a, the lower end face of the exterior wall material 5 is brought into abutment with the positioning portion 29b of the first waterproofing member 7 as shown in
Then, for example, a plurality of nails 41 are driven into the exterior wall material 5 that has been positioned in the above-described manner from the outer surface 5a side of the exterior wall material 5, with a resin spacer member 39 interposed between the back surface 5b of the exterior wall material 5 and the horizontal furring strip 15b, and thus, the exterior wall material 5 is fixed to the horizontal furring strip 15b together with the spacer member 39. At this time, each of the nails 41 is driven into the exterior wall material 5 at a position spaced farther away from the outer surface 132 than the end portion of the first waterproofing member 7. Consequently, in this exterior wall structure, the first waterproofing member 7 is prevented from being damaged by the distal ends of the nails 41 when the exterior wall material 5 is fixed to the horizontal furring strip 15b. Note that the spacer member 39 is not necessarily formed of resin, and is formed of metal or wood, for example. In addition, the thickness of the spacer member 39 is adjustable as appropriate.
As a result of the lower end face of the exterior wall material 5 coming into abutment with the positioning portion 29b, the first seal portion 31 comes into abutment with the back surface 5b of the exterior wall material 5 while being compressed and deformed between the exterior wall material 5 and the fixing portion 29a of the first waterproofing member 7. Thus, the exterior wall material 5 is mounted to the building 1 above the sash body 3a. As a result of the exterior wall material 5 being mounted to the building 1 in this way, the fixing portion 29a is located between the exterior wall material 5 and the horizontal furring strip 15b. Accordingly, the fixing portion 29a is concealed from the exterior side by the exterior wall material 5. Further, the provision of the spacer member 39 between the back surface 5b of the exterior wall material 5 and the horizontal furring strip 15b allows the exterior wall material 5 and the horizontal furring strip 15b to be fixed in a state in which they are spaced apart from each other by an amount corresponding to the thickness of the spacer member 39. Specifically, in this exterior wall structure, the thickness of the spacer member 39 is set to about 5 mm, for example. Note that the number of the nails 41 required to fix the exterior wall material 5 to the building 1 can be changed as appropriate. In place of the nails 41, a plurality of screws can be used to fix the exterior wall material 5 to the horizontal furring strip 15b together with the spacer member 39.
Likewise, for the exterior wall material 5 disposed below the sash body 3a, the upper end face of the exterior wall material 5 is brought into abutment with the positioning portion 29b of the second waterproofing member 8. Consequently, the exterior wall material 5 is positioned below the sash body 3a in a state in which it is spaced apart from the outer surface 132 of the sash body 3a at the above-described interval W1. By fixing the exterior wall material 5 to the horizontal furring strip 15b by means of the nails 41 in this state, the exterior wall material 5 is mounted to the building 1 below the sash body 3a.
For the exterior wall material 5 disposed on the right side of the sash body 3a, the left end face of the exterior wall material 5 is brought into abutment with the positioning portion 29b of the third waterproofing member 9. Consequently, the exterior wall material 5 is positioned on the right side of the sash body 3a in a state in which it is spaced apart from the outer surface 132 of the sash body 3a at the above-described interval W1. For the exterior wall material 5 disposed on the left side of the sash body 3a, the right end face of the exterior wall material 5 is brought into abutment with the positioning portion 29b of the fourth waterproofing member 10. Consequently, the exterior wall material 5 is positioned on the left side of the sash body 3a in a state in which it is spaced apart from the outer surface 132 of the sash body 3a at the above-described interval W1. Note that the exterior wall materials 5 that are disposed on the right side and the left side, respectively, of the sash body 3a are mounted to the building 1 by means of known joint fittings (not shown). Consequently, in the building 1, the exterior wall materials 5 are mounted around the sash body 3a in a state in which they are spaced apart from the sash body 3a at the interval W1, thus completing the exterior wall material mounting step.
After completion of the exterior wall material mounting step, a facing member mounting step is performed in which a facing member 43 is mounted around the window sash 3 as shown in
A fixing portion 431a, as well as a first engaging portion 431b and a second engaging portion 431c are formed in the base member 431. A facing 432a is formed on the top member 432. Additionally, a first engaged portion 432b and a second engaged portion 432c are formed on the back surface side of the facing 432a of the top member 432.
The fixing portion 431a of the base member 431 is mounted to the separating portion 29c of the first waterproofing member 7 by means of a second mounting screw 45. Consequently, the base member 431 is disposed between the outer surface 132 of the sash body 3a and the lower end face of the exterior wall material 5 at a position located on the exterior face 290a side of the separating portion 29c. Note that the length of the second mounting screw 45 is adjusted such that the distal end does not come into contact with the waterproof tape 23 or the flange 3b when the fixing portion 431a is mounted to the separating portion 29c.
The top member 432 is assembled to the base member 431 by causing the first and second engaged portions 432b and 432c to be engaged with the first and second engaging portions 431b and 431c, respectively, of the base member 431. Thus, the top member 432 is disposed on the exterior side of the base member 431. Consequently, the facing 432a of the top member 432 covers the positioning portion 29b, the separating portion 29c, and the supporting portion 29d of the first waterproofing member 7, as well as a part of the exterior wall material 5.
The base member 431 and the top member 432 are also provided between the exterior wall material 5 and the sash body 3a below and to the right and left sides of the sash body 3a in the same manner, completing the facing member mounting step. Thus, the installation of the exterior wall structure is completed. Note that the facing member mounting step is not essential for this exterior wall structure, and is omissible.
The exterior wall structure that has been installed in the above-described manner includes the first to fourth waterproofing members 7 to 10. For each of the first to fourth waterproofing members 7 to 10, the second seal portion 33 is brought into abutment with the outer surface 132 of the sash body 3a. Consequently, with this exterior wall structure, it is possible to easily perform positioning at the time of fixing the first to fourth waterproofing members 7 to 10 to the vertical furring strip 15a and the horizontal furring strip 15b. Then, in a state in which the second seal portion 33 is brought into abutment with the outer surface 132, the fixing portion 29a is fixed to the vertical furring strip 15a and the horizontal furring strip 15b by means of the first mounting screws 35. At this time, with this exterior wall structure, the second seal portion 33 is attached to the outer surface 132 by using double-sided adhesive tape. Consequently, to fix the first to fourth waterproofing members 7 to 10 to the vertical furring strip 15a and the horizontal furring strip 15b by means of the first mounting screws 35, it is possible to suitably prevent the first to fourth waterproofing members 7 to 10 from being displaced from the vertical furring strip 15a and the horizontal furring strip 15b. Accordingly, with this exterior wall structure, it is possible to easily fix the first to fourth waterproofing members 7 to 10 to the vertical furring strips 15a and the horizontal furring strips 15b.
Also, in this exterior wall structure, in a state in which the first to fourth waterproofing members 7 to 10 are fixed to the vertical furring strip 15a and the horizontal furring strip 15b, the end faces of the exterior wall materials 5 are brought into abutment with the positioning portions 29b of the first to fourth waterproofing members 7 to 10. Consequently, with this exterior wall structure, the outer surface 132 of the sash body 3a and the exterior wall materials 5 are uniformly positioned at the interval W1 in the up-down direction of
Also, in this exterior wall structure, the first seal portion 31 is provided on the fixing portion 29a of each of the first to fourth waterproofing members 7 to 10, and the second seal portion 33 is provided on each of the supporting portions 29d. Consequently, by simply fixing the first to fourth waterproofing members 7 to 10 to the vertical furring strips 15a and the horizontal furring strips 15b and bringing the end faces of the exterior wall materials 5 into abutment with the positioning portions 29b in the above-described manner, it is possible, using the first seal portions 31, to prevent the entry of water into the interior side from between the first to fourth waterproofing members 7 to 10 and the exterior wall materials 5. Further, it is possible, using the second seal portions 33, to prevent the entry of water into the interior side from between the first to fourth waterproofing members 7 to 10 and the outer surface 132 of the sash body 3a. Accordingly, although filling with the caulking compound 37 is supplementally performed to waterproof the building 1, it is possible to reduce the number of locations filled with the caulking compound 37. Consequently, with this exterior wall structure, the waterproofing of the building 1 is easily achieved. Note that the caulking compound filling step is omissible for this exterior wall structure as described above. In this case, it is not necessary to fill with the caulking compound 37 to waterproof the building 1, making it possible to waterproof the building 1 more easily.
Accordingly, with the exterior wall structure according to the embodiment, it is possible to accurately position the exterior wall materials 5, ensure the waterproofness of the building 1 to which the window sash 3 and the exterior wall materials 5 are mounted, and achieve easy installation.
In particular, with this exterior wall structure, the interval from the outer surface 132 of the sash body 3a to the positioning portions 29b, or in other words, the interval between the outer surface 132 of the sash body 3a and the end faces of the exterior wall materials 5 is determined by the length of the separating portions 29c of the first to fourth waterproofing members 7 to 10 in the width direction. Accordingly, the interval between the outer surface 132 of the sash body 3a and the exterior wall materials 5 is easily set to a length other than the above-described interval W1, for example, by changing the length of the separating portions 29c in the width direction according to the shape of the facing member 43 or the design of the building 1.
Further, in this exterior wall structure, the waterproof tape 23 or the flange 3b is prevented from the damages caused by contacting with the distal ends of the first and second mounting screws 35 and 45 and the nails 41 when the first to fourth waterproofing members 7 to 10, the exterior wall materials 5 and the base members 431 of the facing member 43 are mounted. Accordingly, with this exterior wall structure, it is not necessary to perform an operation such as additionally filling with the caulking compound 37 to prevent the entry of water into the interior side from the gap in the waterproof tape 23 or the flange 3b that has been damaged by the first mounting screws 35 or the like. Therefore, it is possible to easily waterproof the building 1.
Furthermore, with this exterior wall structure, the facing member 43 is provided around the window sash 3, and therefore, the separating portions 29c of the first to fourth waterproofing members 7 to 10 and the like are concealed from the exterior side of the building 1 by the facings 432a of the top members 432.
In this exterior wall structure, the separating portions 29c are located on the interior side with respect to the outer surfaces 5a of the exterior wall materials 5 when the exterior wall materials 5 are mounted to the building 1. Accordingly, the separating portions 29c do not protrude to the exterior side with respect to the outer surfaces 5a of the exterior wall materials 5 between the outer surface 132 of the sash body 3a and the end faces of the exterior wall materials 5. Consequently, the facing member 43 does not unnaturally protrude to the exterior side when the facing member 43 is mounted, making it possible to enhance the aesthetic appearance of the building 1. Since the separating portions 29c do not protrude to the exterior side with respect to the outer surfaces 5a of the exterior wall materials 5, the separating portions 29c are less noticeable between the outer surface 132 of the sash body 3a and the end faces of the exterior wall materials 5 when the building 1 is viewed from the exterior side even if the facing member mounting step is omitted and the facing member 43 is not provided. Consequently, with this exterior wall structure, the aesthetic appearance of the building 1 is enhanced even if the facing member 43 is not provided.
Furthermore, the separating portion 29c is formed flat, and it is therefore possible to easily form the separating portion 29c, as well as the fixing portion 29a, the positioning portion 29b, and the supporting portion 29d on the waterstop body 29 by press working a metal plate. This makes it possible to reduce the manufacturing cost for the first to fourth waterproofing members 7 to 10 and hence the cost required to install the exterior wall structure.
Since the separating portion 29c is flat, the installation of the base member 431 is easier. In addition, it is possible to enhance the aesthetic appearance of the building 1 even if the facing member mounting step is omitted as described above.
Furthermore, in this exterior wall structure, as a result of the exterior wall materials 5 being mounted to the building 1, the first seal portions 31 are located between the back surfaces 5b of the exterior wall materials 5 and the fixing portions 29a of the first to fourth waterproofing members 7 to 10. Also, the supporting portion 29d is formed by being bent from the end portion of the other end side of the separating portion 29c toward the interior side. Thereby, with this exterior wall structure, the supporting portions 29d and the second seal portions 33 are not exposed on the exterior side when the first to fourth waterproofing members 7 to 10 are mounted around the sash body 3a. Accordingly, with the exterior wall structure, it is possible to enhance the aesthetic appearance of the building 1, and suitably prevent the first and second seal portions 31 and 33 from being degraded by ultraviolet radiation.
Although the present invention has been described above by way of an embodiment, the present invention is by no means limited to the above-described embodiment. Needless to say, modifications can be made as appropriate without departing from the scope and spirit of the invention.
For example, in the present embodiment, the exterior wall material and the waterproofing member are mounted by using the furring strip as the wall backing member. Alternatively, the exterior wall material and the waterproofing member are directly mounted to the frame member in an installation method that does not use a wall backing member.
For example, depending on the position at which the window sash 3 is provided in the building 1, the first waterproofing member 7 or the like is mounted in only one location such as above the sash body 3a. The exterior wall structure according to the embodiment is also used, for example, around a door of the building 1. In this case, a door is an example of the opening member according to the present invention. Furthermore, the exterior wall structure according to the embodiment is also used for a building other than the wooden building 1.
In the exterior wall structure according to the embodiment, the length of the waterstop body 29 of the first waterproofing member 7 in the longitudinal direction is defined according to the length of the sash body 3a in the left-right direction to be one long first waterproofing member 7. However, the present invention is not limited thereto, and the length of the waterstop body 29 in the longitudinal direction is alternatively formed to be shorter than the length of the sash body 3a in the left-right direction, and a plurality of short first waterproofing members 7 are disposed above the sash body 3a. The same applies to the second to fourth waterproofing members 8 to 10.
Furthermore, the waterstop body 29 is alternatively designed such that the length by which the positioning portion 29b extends to the exterior side is equivalent to the length of the exterior wall material 5 in the thickness direction, or longer than the length of the exterior wall material 5 in the thickness direction. In this case, depending on the length by which the positioning portion 29b extends to the exterior side, the exterior face 290a of the separating portion 29c and the outer surface 5a of each of the exterior wall materials 5 constitute substantially identical continuous surfaces, or the separating portion 29c protrudes to the exterior side by a certain amount with respect to the outer surface 5a of each of the exterior wall materials 5.
