JP 2003-328529 A

  By the way, in the above-mentioned waterproofing member, since the waterproofing material is configured to be in contact with the back surface of the outer wall member, it does not easily deteriorate over time as compared with the exposed caulking material, but because the waterproofing material is used for a long period of time, the waterproofing material has a small amount. Deterioration over time. For this reason, there is still room for improvement in the above-mentioned waterproof member in terms of waterproofness.

  The present invention has been made in view of the above, and can further improve waterproofness, and satisfactorily prevent water that has entered from a joint portion from coming into contact with a member provided inside an outer wall member. It is one of the purposes.

  The waterproof member of the outer wall member of the present invention employs the following means in order to achieve the above object.

According to a preferred embodiment of the waterproofing member of the outer wall member according to the present invention, the waterproofing member of the outer wall member used for the outer wall member attached in a state where the end portions are in contact with each other, and is configured to be elongated. The base portion is configured to be attached to a member disposed inside the outer wall member so that the longitudinal direction is along the joint portion of the adjacent outer wall member, and the back surface of each of the two outer wall members forming the joint portion is contacted. A contact portion having a seal portion configured to be in contact with, and arranged to be bent and inclined with respect to the substrate portion, to connect the substrate portion and the contact portion, and to form the contact portion via the seal portion. An elastic portion that elastically urges the rear surface of the outer wall member. Here, the “member disposed inside the outer wall member” in the present invention typically corresponds to a main pillar, a stud, and a corner post, but is attached and fixed to the main pillar, a stud, and a corner post. This is a concept that includes the torso.

  According to the present invention, the abutting portion is configured to be abutted against the back surface of the outer wall member in a state of being elastically urged by the elastic portion. Good contact with the outer wall member can be maintained. This makes it possible to further improve the waterproofness at the joint of the outer wall member.

According to a preferred embodiment of the waterproof member of the outer wall member according to the present invention, the board portion has an attaching portion attached to a member disposed inside the outer wall member. The elastic portion is formed by bending both end portions extending from the substrate portion in the same direction as the inclined portion with respect to the substrate portion. The dimension from the substrate portion to the portion where the seal portion contacts the back surface of the outer wall member is set to be larger than the size between the member disposed inside the outer wall member and the back surface of the outer wall member. I have. Here, the “both ends extending from the substrate” in the present invention correspond to both ends along the longitudinal direction of the substrate. In the present invention, the “bending process” may be a mode in which both end portions extending from the substrate portion are bent in a direction approaching each other or a mode in which the both end portions are bent in a direction away from each other.

According to this embodiment, both ends extending from the substrate portion are bent, and the dimension from the substrate portion until the seal portion comes into contact with the back surface of the outer wall member is determined by a member disposed outside the outer wall member and the outer wall member. Since the configuration is only set so as to be larger than the dimension between the rear surface and the rear surface, the configuration in which the contact portion having the seal portion elastically contacts the rear surface of the outer wall member can be easily secured. Further, it is possible to reduce the distance between the rear surface of the abutment portion and the outer wall member having a sealing portion by the elastic unit, it is possible to reduce the thickness of the person the seal portion. As a result, the amount of the relatively expensive waterproof material can be reduced, which can contribute to cost reduction.

  According to a further aspect of the waterproofing member of the outer wall member according to the present invention, the elastic portion bends both side ends of the substrate portion so that a cross-sectional shape in a cross section perpendicular to the longitudinal direction of the substrate portion is substantially V-shaped. It is constituted by processing. According to this embodiment, since the substrate portion is merely bent in a substantially V shape, the elastic portion can be more easily secured.

According to a preferred embodiment of the waterproofing member of the outer wall member according to the present invention, the elastic portion is formed by bending the both end portions of the substrate portion a plurality of times in an inclined manner with respect to the substrate portion.

  According to this embodiment, when the outer wall member is attached to the member disposed inside the outer wall member in a state where the outer wall member is in contact with the contact portion, the elastic portion is elastically deformed at a plurality of locations. That is, the restoring force due to the elastic deformation at a plurality of locations acts on the contact portion. Thereby, even if aging occurs in any of the bent portions of the elastic portion, the restoring force of the remaining bent portion can be applied to the contact portion. As a result, the waterproof property at the joint of the outer wall member can be further improved.

According to a further aspect of the waterproof member of the outer wall member according to the present invention, the seal portion is configured to be in surface contact with the back surface.

According to this embodiment, the seal portion can be reliably brought into contact with the back surface of the outer wall member by surface contact. Thereby, waterproofness can be further improved.

According to a further embodiment of the waterproof member outer wall member according to the present invention, the sealing portion is constituted by an elastic body. According to this embodiment, in addition to the elastic force of the elastic portion, the contact of the seal portion with the back surface of the outer wall member can be maintained by the elastic force of the seal portion itself. This makes it possible to further improve the waterproofness at the joint of the outer wall member.

  ADVANTAGE OF THE INVENTION According to this invention, waterproofness can be improved further and the water which invaded from the joint part can be favorably prevented from contacting the member arrange | positioned inside an outer wall member.

  Next, the best mode for carrying out the present invention will be described using an embodiment.

  As shown in FIG. 1, the waterproof member 1 according to the embodiment of the present invention includes a main body 12 and a pair of seals 22 made of a waterproof material attached to the main body 12. The main body 12 is formed by bending a long resin or a steel plate, preferably a long spring steel material (SUP material).

  As shown in FIGS. 1 and 2, the main body 12 includes a substrate 13 and a pair of elastic portions 14 provided on both sides of the substrate 13 (in the left-right direction in FIGS. 1 and 2). And a pair of flange portions 15 provided at one end of the pair of elastic portions 14, and the cross-sectional shape in a direction perpendicular to the longitudinal direction is configured as a hat shape. The substrate portion 13 is formed in a flat plate shape, and the substrate portion 13 and the pair of elastic portions 14 form a concave portion 12a. The plane opposite to the side on which the pair of elastic portions 14 extend (opposite to the concave portion 12a) among the planes forming the substrate section 13 is the mounting surface 13a to be attached to the body edge 52 described later. . The pair of flange portions 15 are configured to project in a direction perpendicular to the longitudinal direction with the concave portion 12a interposed therebetween, that is, to extend in a direction away from each other. Note that the pair of flange portions 15 are configured to be parallel to the substrate portion 13. The pair of flange portions 15 is an example of a “contact portion”.

  In the present embodiment, the pair of seal portions 22 are made of, for example, an elastic foamed resin such as EPDM sponge or vinyl chloride. The seal portion 22 is formed in a substantially rectangular parallelepiped as shown in FIG. 1, and is attached and fixed to each of the pair of flange portions 15 as shown in FIGS. A plane opposite to the plane that contacts the flange section 15 (the side opposite to the plane that contacts the flange section 15) of the planes forming the seal section 22 corresponds to the outer wall panel 32 and the output wall described later. A pair of contact surfaces 22a that contact the corner members 34 are formed.

  As shown in FIG. 2, the waterproof member 1 thus configured has a distance (hereinafter, referred to as “height h”) from the mounting surface 13 a of the substrate portion 13 to the contact surfaces 22 a of the pair of seal portions 22. The gap is set to be slightly larger than a gap CL (see FIG. 4) having a predetermined size formed between the panel 32 and the corner material 34 and the body edge 52.

  Next, a description will be given of waterproofing at the joint between the outer wall members 30 using the waterproofing member 1 thus configured. In the present embodiment, a description will be given of waterproofing at a joint J formed along the vertical direction among joints between the outer wall panel 32 and the corner material 34 as a joint between the outer wall members 30. Note that the corner material 34 is configured as a member that covers a corner (corner) formed by the outer wall members 30 intersecting at a predetermined angle (for example, 90 degrees), and has a substantially L-shaped cross section. It has a shape. In addition, as shown in FIG. 4, chamfering is performed on the outdoor side corners of the fore edge portions 32a and 34a constituting the joint J between the outer wall panel 32 and the corner material 34. By performing the chamfering process, the design of the appearance when the outer wall panel 32 and the corner material 34 are fastened to the body edge 52 is improved. Hereinafter, for convenience of description, the upper direction in FIG. 3 is defined as “upper” or “upper”, and the lower direction in FIG. 3 is defined as “lower” or “lower”.

  First, the waterproof member 1 is attached and fixed to the rim 52 attached and fixed to the front side (outdoor side) of the corner post 72 arranged at the corner of the building. Here, the waterproof member 1 is attached and fixed such that the longitudinal direction of the waterproof member 1 is along the longitudinal direction of the trunk edge 52 as shown in FIG. More specifically, as shown in FIG. 4, the waterproof member 1 is configured such that the mounting surface 13 a of the substrate portion 13 abuts on the body edge 52, and the abutting surface of one of the pair of seal portions 22. 22a is attached to the back surface (indoor side surface) of the outer wall panel 32, and the contact surface 22a of the other seal portion 22 is attached to the back surface (indoor side surface) of the corner material 34. That is, in the waterproof member 1, the substrate 13 is arranged at a position facing the joint J between the outer wall panel 32 and the corner material 34, and the pair of seals 22 are arranged on both sides of the joint J. Is fixed to the waist edge 52. At this time, the concave portion 12a, the pair of flange portions 15, the pair of seal portions 22, and the back surface of the outer wall panel 32 and the corner material 34 constitute a drain groove 40 for flowing water that has entered from the joint portion J downward. You. The attachment of the waterproof member 1 to the body edge 52 is performed by using, for example, an adhesive, a double-sided tape, a nail, or the like. The waist edge 52 is an example of a “member disposed inside the outer wall member”.

  Then, as shown in FIG. 3, the outer wall panel 32 and the corner material 34 are fastened to the corner pillar 72 via the trunk edge 52 by an appropriate method using the support fittings 62 and 64. The outer wall panel 32 and the corner material 34 are attached so that a gap CL having a predetermined dimension is provided between the outer wall panel 32 and the corner member 34 as shown in FIG. The gap CL is provided in order to ensure ventilation and drainage between the outer wall panel 32 and the corner material 34 and the body edge 52.

  Here, since the height h of the waterproof member 1 is set to be a value slightly larger than the gap CL, the outer wall panel 32 and the corner material 34 are brought into contact with the pair of seal portions 22 so that the body is closed. When attached to the edge 52, the concave portion 12a is slightly opened, that is, the pair of elastic portions 14 are elastically deformed in the falling direction (from the two-dot chain line to the solid line in FIG. 4). As a result, a restoring force is generated due to the elastic deformation of the pair of elastic portions 14, and the pair of seal portions 22 are elastically urged against the back surfaces of the outer wall panel 32 and the corner material 34 by the restoring force. For this reason, even if the seal part 22 deteriorates over time, it is possible to maintain good contact of the seal part 22 with the outer wall panel 32 and the back surface (indoor screen) of the corner material 34. As a result, the waterproof property at the joint J is further improved.

  In addition, since the pair of flange portions 15 are configured to be parallel to the substrate portion 13, the contact surfaces 22a of the pair of seal portions 22 and the outer wall panel 32 and the corner material 34 are surely brought into surface contact. Can be done. Thereby, the waterproofness at the joint J is further improved. As described above, since the waterproof property at the joint J is further improved, the step of filling the joint J with the caulking material can be omitted. In addition, since the pair of seal portions 22 themselves also have elasticity, when the pair of seal portions 22 abut against the outer wall panel 32 and the back surface of the corner material 34, the pair of seal portions 22 are compressed and deformed. Due to the restoring force due to the compressive deformation, the adhesion of the pair of seal portions 22 to the outer wall panel 32 and the back surface (indoor side surface) of the corner material 34 is improved. The water that has entered from the joint J flows downward along the drain groove 40 and is discharged to the outside. Therefore, it is possible to satisfactorily prevent the water that has entered from the joint J from coming into contact with the members disposed inside the outer wall panel 32 and the corner material 34 such as the rim 52.

  In the present embodiment, the pair of flange portions 15 are configured to be parallel to the substrate portion 13, but the present invention is not limited to this. For example, as exemplified in the waterproofing member 101 of the modified example in FIG. 5, the virtual extension line VL1 of the pair of flange portions 115 and the virtual line VL1 of the substrate portion 113 are larger than the included angle α formed by the pair of elastic portions 114 and the substrate portion 113. The pair of flange portions 115 may be inclined with respect to the substrate portion 13 so that the included angle β formed by the virtual extension line VL2 is larger.

  According to this configuration, when the outer wall panel 32 and the corner material 34 are attached to the body edge 52, the pair of elastic portions 114 and the pair of flange portions 115 have a pair of flanges 115 in the direction in which the included angles α and β increase. The elastic portion 114 and the pair of flange portions 115 are elastically deformed. That is, the restoring force due to the elastic deformation of both the pair of elastic portions 114 and the pair of flange portions 115 acts on the pair of seal portions 122. Accordingly, even if one of the pair of elastic portions 114 and the pair of flange portions 115 is deteriorated due to aging, the other restoring force of the pair of elastic portions 114 and the pair of flange portions 115 acts on the pair of seal portions 122. be able to. As a result, the waterproof property at the vertical joint J between the outer wall panel 32 and the corner material 34 can be further improved.

In this embodiment and above modification, the main body portion 12, 112 is the substrate portion 13, 113, a configuration having a pair of resilient portions 14, 114 and a pair of flange portions 15, 115, Reference Example 6 As shown in the example of the waterproof member 201, the main body portion 212 has only the substrate portion 213 and the pair of elastic portions 214, that is, the cross-sectional shape in the direction perpendicular to the longitudinal direction of the main body portion 212 is substantially V-shaped. A configuration is possible . According to this configuration, since the steel plate is merely bent in a substantially V shape, the waterproof member 201 can be configured more easily .

In the present embodiment and the above-described modifications, the present invention is applied to waterproofing between the outer wall members 30 in a mode in which the outer wall panel 32 and the corner material 34 are in contact with each other. However, the present invention is not limited to this. For example, the present invention can be applied to waterproofing between the outer wall members 30 in a mode in which the joint J between the outer wall panel 32 and the corner material 34 is filled with a caulking material. In this case, the waterproof member 301 of the reference example illustrated in FIG. 7 can be used. The waterproof member 301 of the reference example has the same configuration as the waterproof member 1 of the present embodiment except that it has a protrusion 316. That is, in the waterproof member 301 of the reference example, as shown in FIG. 7, a protruding portion 316 that protrudes in a direction perpendicular to the substrate portion 313 is provided at the center of the substrate portion 313.

The waterproof member 301 of the reference example thus configured is attached to the body edge 52, and the outer wall panel is arranged so that the back surfaces (indoor side surfaces) of the outer wall panel 32 and the corner material 34 come into contact with the pair of seal portions 322 of the waterproof member 301. 32 and the corner material 34 are fastened to the rim 52. At this time, the protrusion 316 of the waterproof member 301 is fastened so as to be sandwiched between the outer wall panel 32 and the small edge portions 32a and 34a of the corner material 34. As a result, the joint groove 90 is formed by the front edge portions 32 a and 34 a of the outer wall panel 32 and the corner material 34 and the protrusion 316. By filling the joint groove 90 with the caulking material 92, the joint J between the outer wall panel 32 and the corner material 34 is sealed. The fore-edge surfaces 32a and 34a are examples of "each side surface of the outer wall member". The joint groove 90 is an example of a “region for filling a sealing material”, and the caulking material 92 is an example of a “sealing material”.

  Also in this configuration, by setting the height h of the waterproof member 301 to be a value slightly larger than the gap CL, the pair of seal portions 322 can be separated from the outer wall panel 32 by the restoring force due to the elastic deformation of the pair of elastic portions 314. And it can elastically urge the back surface of the corner material 34. Therefore, even if the caulking material 92 deteriorates over time, it is possible to satisfactorily prevent water that has entered from the joint J from coming into contact with the rim 52. Further, even if the seal portion 322 deteriorates over time, the contact of the seal portion 322 with the outer wall panel 32 and the back surface (indoor screen) of the corner material 34 can be favorably maintained. Water resistance can be further improved.

In the present embodiment and the above-described modified examples and reference examples, the pair of elastic portions 14, 114, 214, 314 are bent at an inclination angle in a direction away from each other, but the waterproof member of the modified example of FIG. As shown in the example 401, the pair of elastic portions 14, 114, 214, 314 may be bent at an inclination angle in a direction approaching each other. As shown in the reference example of FIG. 8B, the pair of flange portions 415 may not be provided. In this case, the pair of seal portions 422 are attached to the pair of elastic portions 414.

In the present embodiment and the above-described modified examples and reference examples , the pair of flange portions 15, 115, 315, and 415 are configured to extend in a direction away from each other. As such, the pair of flange portions 515 may be configured to extend in a direction approaching each other.

In the present embodiment and the modified examples and the reference examples described above, the seal portions 22, 122, 222, 322, 422, and 522 are provided, but the seal portions 22, 122, 222, 322, 422, and 522 are not provided. Is also good. In this case, at least a part of the pair of flange portions 15, 115, 315, 415, 515 or the pair of elastic portions 14, 114, 214, 314, 414, 515 is formed on the back surface of the outer wall panel 32 and the corner material 34 (inside of the indoor). ). The pair of flange portions 15, 115, 315, 415, 515 and the pair of elastic portions 14, 114, 214, 314, 414, 515 are in surface contact with the back surface (indoor side surface) of the outer wall panel 32 and the corner material 34. It is desirable to be configured to be able to do so.

In the present embodiment and the above-described modified example, the configuration is such that the elastic force is urged to the seal portion 22 by bending the main body portion 12, but as illustrated in the waterproof member 601 of the reference example in FIG. Alternatively, a pair of seal portions 622 may be attached to the main body portion 612 having a flat plate shape via a pair of spring members 80. Note that a leaf spring can be used as the spring member 80.
