Description

  The present invention relates to an outer wall joint structure.

  Patent Document 1 below discloses an outer wall joint structure in which a backup material is inserted into a vertical joint of an outer wall panel and filled with a sealing material.

JP 2003-239491 A

  In the outer wall joint structure of Patent Document 1 described above, when the outer wall panel moves during an earthquake or the like, the joint surface between the sealing material and the outer wall panel may break. In such a case, the water stop performance by the sealing material is deteriorated, and rainwater may enter the indoor side of the outer wall panel from the fractured joint surface.

  In view of the above facts, an object of the present invention is to provide an outer wall joint structure in which the water stop performance is hardly deteriorated even if a plate material constituting the wall moves.

The outer wall joint structure according to the first aspect includes a plate-like first outer wall material in which a groove portion having an inclined groove wall is formed along a side end surface, and a side end surface in which a protrusion engaging with the groove portion faces the side end surface. A plate-like second outer wall material formed along the elastic material, and arranged in a compressed state between the groove wall and the protrusion, and the first outer wall material and the second outer wall. A vertical joint water-stopping member that stops water between the outside and inside of the material,
It has.

  According to the outer wall joint structure of the first aspect, the groove wall of the groove formed along the side end surface of the first outer wall material is inclined. And the vertical joint water stop member comprised with the elastic material is compressed and arrange | positioned between this inclined groove wall and the protrusion formed along the side end surface of the 2nd outer wall material.

  As a result, when at least one of the first outer wall material or the second outer wall material moves in a direction in which the side end surfaces of the first outer wall member and the second outer wall member separate from each other (in the left-right direction when the first outer wall member is viewed from the front), or the side end surfaces of each other shift. In any case when moving in the direction (front-rear direction when the first outer wall material is viewed from the front), the compressed vertical joint water-stopping member approaches the original state, and the state in contact with the groove wall and the ridge is maintained. Therefore, a gap is hardly generated between the vertical joint water-stopping member, the groove wall, and the protrusion. For this reason, the water stop performance between the outer side and the inner side of the first outer wall material and the second outer wall material is unlikely to deteriorate. “Outside” refers to the outdoor space, and “inside” refers to the indoor space.

In the outer wall joint structure of the second aspect, a plate-like first outer wall material in which the groove portion is formed along the side end surface, and a protrusion that engages with the groove portion is formed along the side end surface facing the side end surface. A plate-like second outer wall material and an elastic material, and arranged in a compressed state between the side end surface of the first outer wall material and the side end surface of the second outer wall material, And a vertical joint water-stopping member that stops water between the outside and the inside of the outer wall material and the second outer wall material.

  According to the outer wall joint structure of the second aspect, a vertical joint water-stopping member made of an elastic material is compressed and disposed between the side end surface of the first outer wall member and the side end surface of the second outer wall member. Has been.

  Thereby, when at least one of the first outer wall member or the second outer wall member moves in a direction in which the side end surfaces of the first outer wall member and the second outer wall member separate from each other (left and right direction when the first outer wall member is viewed from the front), Since the state which contacted the side end surface of the 1st outer wall material and the side end surface of the 2nd outer wall material is maintained by approaching the original state, a vertical joint water stop member, the side end surface of the 1st outer wall material, and 2nd It is difficult for a gap to be formed between the side wall surfaces of the outer wall material. In addition, even when moving in the direction in which the side end faces deviate from each other (front-back direction when the first outer wall material is viewed from the front), the vertical joint water-stopping member is maintained in a compressed state. A gap is unlikely to occur between the side end surface of the first outer wall material and the side end surface of the second outer wall material. For this reason, the water stop performance between the outer side and the inner side of the first outer wall material and the second outer wall material is unlikely to deteriorate.

  The outer wall joint structure of the third aspect is disposed on a horizontal joint formed below the first outer wall member and the second outer wall member, receives the flowing water that has flowed through the vertical joint water-stopping member, and moves outward. A water receiving member is provided.

  According to the outer wall joint structure of the third aspect, rainwater that has flowed along the vertical joint water-stopping member at the vertical joint between the first outer wall member and the second outer wall member is received by the water receiving member, and the outside (outdoor side) ). This makes it difficult for rainwater that has flowed from the vertical joint to the horizontal joint to enter the inside (indoor side space) through the horizontal joint.

  In the outer wall joint structure of the fourth aspect, the water receiving member has a water receiving portion disposed on the indoor side of the vertical joint water-stopping member in plan view, and extends from both ends of the water receiving portion toward the outdoor side. A water guide portion.

  According to the outer wall joint structure of the fourth aspect, rainwater that flows along the vertical joint water-stopping member at the vertical joint between the first outer wall member and the second outer wall member is stopped by the water receiving portion. Moreover, the rainwater stopped by the water receiving part flows to the outdoor side of the horizontal joint along the water guiding part.

  Thereby, when there is a vertical joint further below the vertical joint between the first outer wall member and the second outer wall member, the rainwater stopped by the water receiving portion flows downward along the vertical joint. Or it flows to the outdoor side of the horizontal joint along the water guide.

  Moreover, when there is no vertical joint below the vertical joint between the first outer wall member and the second outer wall member, rainwater stopped by the water receiving portion flows to the outdoor side of the horizontal joint along the water guide portion.

  In the outer wall joint structure of the fifth aspect, the water receiving member has a bottom plate formed in a portion surrounded by the water receiving portion and the water guide portion, and is disposed on the outer surface of the water guide portion along the horizontal joint. The end surface of the horizontal joint waterproof member is abutted.

  According to the joint structure of the outer wall of the fifth aspect, since the bottom plate is formed on the water receiving member at the portion surrounded by the water receiving portion and the water guiding portion, it is difficult for rainwater to flow below the water receiving member. Thereby, the rainwater stopped by the water receiving part flows to the outdoor side along the water guiding part. Furthermore, since the end face of the horizontal joint water-stopping member is abutted against the outer surface of the water guide portion, rainwater that flows to the outdoor side along the water guide portion is suppressed from flowing from the outside of the water guide portion to the indoor side.

  According to the joint structure of the outer wall of the first aspect, the water stop performance is not easily lowered even if the plate material constituting the wall moves.

  According to the joint structure of the outer wall of the second aspect, the water stopping performance is not easily lowered even if the plate material constituting the wall moves.

  According to the outer wall joint structure of the third aspect, rainwater flowing from the vertical joint to the horizontal joint can be prevented from entering the indoor side from the horizontal joint.

  According to the outer wall joint structure of the fourth aspect, rainwater that has flowed from the vertical joint to the horizontal joint can flow to the lower vertical joint or the outdoor side of the horizontal joint.

  According to the outer wall joint structure of the fifth aspect, even when there is no vertical joint below the horizontal joint, rainwater flowing from the vertical joint to the horizontal joint can be prevented from entering the indoor side from the horizontal joint.

[First Embodiment]
(Outer wall joint structure)
The outer wall joint structure in the first embodiment is a waterproof structure applied to the vertical joint 20 and the horizontal joint 30 of the outer wall panel 12 constituting the wall body 10 shown in FIG.

  The outer wall panel 12 is an ALC (lightweight cellular concrete) plate, and is fixed to the building housing on the back side of the paper in FIG.

  The vertical joint 20 between the outer wall panels 12 adjacent to each other has a continuous joint configuration (through joint, joint joint) between the upper and lower outer wall panels 12, and at the intersection E <b> 1 of the vertical joint 20 and the horizontal joint 30. The sealing material 42 that stops the vertical joint 20 is used as a threading material, and the sealing material 44 that stops the horizontal joint 30 is pressed against and adhered to the sealing material 42.

  The sealing materials 42 and 44 are non-uniform sealing materials (elastic sealing) that stop the vertical joint 20 and the horizontal joint 30 at the portion closest to the outdoor side, respectively, and after the outer wall panel 12 is fixed to the building frame, caulking is performed. Filled with a gun. In the following description, the sealing materials 42 and 44 may be collectively referred to as a primary water blocking material 40. Further, as the material of the sealing materials 42 and 44, a resin such as silicon, modified silicon, or polyurethane is appropriately used.

(Vertical joint)
As shown in FIGS. 1 and 2, the vertical joint 20 is a joint between two outer wall panels 12 (outer wall panels 12 </ b> A and 12 </ b> B) that are adjacent to each other in the lateral direction while being fixed to a building frame (not shown). .

  As shown in FIG. 2, a groove 14 is formed on one side end surface of the outer wall panel 12, and a ridge (so-called fruit) 16 is formed on the other side end surface. The groove 14 and the protrusion 16 are formed along the side end surface from the upper end to the lower end of the outer wall panel 12.

  The groove wall 14A of the groove portion 14 is inclined in a direction away from each other toward the side end face 12E of the outer wall panel 12 from the groove bottom 14B. Further, the side walls 16A of the ridges 16 are inclined in directions away from each other toward the side end face 12E from the top face 16B.

  The outer wall panel 12 is fixed to a building housing (not shown), and is opposed to the outer wall panel 12A in the other outer wall panel 12B with respect to the groove portion 14 formed on the side end surface of one of the adjacent outer wall panels 12A. The ridge 16 formed on the side end surface to be engaged is disposed.

  As shown in FIG. 2, “engagement” refers to a state in which the side end faces 12E are in contact with each other, the groove wall 14A and the side wall 16A are in contact with each other, and the outer wall panels 12A and 12B are viewed from the front. It includes a state where a gap is opened between the outer wall panels 12A and 12B to such an extent that the strip 16 overlaps.

(Vertical joint waterproofing member)
In a state where the groove portion 14 and the protrusion 16 are engaged, a vertical joint water stop member 52 made of EPDM (ethylene propylene rubber) is held in a compressed state between the groove wall 14A and the side wall 16A. Yes. The state before compression is indicated by a broken line in FIG. Further, as the material of the vertical joint water-stopping member 52, various closed cell properties such as EPDM, CR (chloroprene) rubber, NR (natural rubber) rubber sponge, NBR (acrylonitrile, butadiene) rubber, etc. The elastic resin material can be used.

  The vertical joint water-stopping member 52 is disposed on the engagement surface between the groove wall 14A and the side wall 16A on the outdoor side (the arrow OUT side in FIG. 2) when viewed from the center line CL of the outer wall panel 12. Further, the above-described sealing material 42 (primary water blocking material 40) is disposed in the notch 18 formed further on the outdoor side than the engagement surface.

  As a result, the vertical joint 20 has a double waterproofing with the sealing material 42 as the primary waterproofing material 40 and the vertical joint waterproofing member 52 as the secondary waterproofing material on the outdoor side of the center line CL of the outer wall panel 12. A water structure is formed.

(Horizontal joint)
As shown in FIG. 1, the horizontal joint 30 is a joint between two outer wall panels 12 (for example, outer wall panels 12 </ b> A and 12 </ b> C) that are adjacent to each other in the vertical direction while being fixed to a building frame (not shown).

  3 shows the structure below the outer wall panels 12A and 12B in FIGS. 1 and 2, that is, the outer wall panels 12C and 12D and the inner structure of the horizontal joint 30 in a plan view. 4 is an exploded perspective view of the outer wall panels 12C and 12D, the internal structure of the horizontal joint 30, and the outer wall panel 12B. In FIG. 4, illustration of the outer wall panel 12A and the sealing material 42 is omitted.

(Water receiving member)
As shown in FIG. 3, a water receiving member 54 made of EPDM is disposed on the horizontal joint 30 so as to surround the vertical joint water-stopping member 52 from the indoor side and the side in a plan view. The water receiving member 54 is a horseshoe provided with a water receiving portion 54A disposed on the indoor side of the vertical joint water-stopping member 52, and a water guiding portion 54B extending from both ends of the water receiving portion 54A toward the outdoor side. It is a water stop member of shape. In FIG. 3, the boundary portion between the water receiving portion 54A and the water guiding portion 54B is represented by a two-dot chain line for convenience.

  The water receiving member 54 is formed by cutting a sheet-like EPDM into a horseshoe shape. As the material of the water receiving member 54, various closed cell resins such as EPDM, CR (chloroprene) rubber, NR (natural rubber) rubber sponge, NBR (acrylonitrile, butadiene) rubber, etc. Materials can be used.

  As shown in FIG. 4, the end face of the horizontal joint water-stopping member 56 disposed along the horizontal joint 30 is abutted against the outer surface of the water guide portion 54 </ b> B in the water receiving member 54. The front surface (outdoor side surface) of the water guiding portion 54B and the side surface (outdoor side surface) of the horizontal joint waterproofing member 56 are substantially flush with each other.

  Further, on the outdoor side of the water receiving member 54 and the horizontal joint water-stopping member 56, the above-described sealing material 44 (primary water-stopping material 40) is disposed. The sealing material 44 is an irregular sealing material (elastic sealing), and the water receiving member 54 and the horizontal joint water-stopping member 56 function as a backup material. In addition, the sealing material 44 and the horizontal joint waterproofing member 56 are arrange | positioned on the outdoor side rather than the centerline CL of the outer wall panel 12. FIG.

  Thereby, in the horizontal joint 30, the double sealant 44 is used as the primary waterproof material 40, and the horizontal joint waterproof member 56 is used as the secondary waterproof material on the outdoor side of the center line CL of the outer wall panel 12. A water stop structure is formed.

(Fireproof joint material)
The horizontal joint 30 is further provided with a fireproof joint material 60. The fireproof joint material 60 is a non-combustible material formed by using a rock wool heat insulating plate, a ceramic fiber blanket, or the like, and is disposed on the indoor side with respect to the water receiving member 54 and the horizontal joint waterproofing member 56.

(Action / Effect)
According to the outer wall joint structure in the first embodiment, as shown in FIG. 2, the seal material 42 is the primary water stop material 40 on the outdoor side of the center line CL of the outer wall panel 12 of the horizontal joint 30, and the vertical joint water stop is performed. A double water stop structure using the member 52 as the secondary water stop material is formed. Therefore, the water stop performance is high compared to the single water stop structure.

  In addition, the vertical joint water-stopping member 52 is held in a compressed state between the groove wall 14A and the side wall 16A in a state where the groove portion 14 and the protrusion 16 are engaged. For this reason, when the outer wall panels 12A and 12B move in a direction away relatively (L direction or R direction in FIG. 2), the vertical joint water-stopping member 52 approaches the original state so that the groove wall 14A and the side wall 16A The contact state is maintained. Further, when the outer wall panels 12A and 12B are moved in directions that are relatively displaced (the IN direction and the OUT direction in FIG. 2), the vertical joint water-stopping member 52 approaches the original state, thereby causing the groove wall 14A and the side wall 16A. The state in contact with is maintained. Thereby, even if outer wall panel 12A, 12B which forms the wall 10 moves, the water stop performance of the wall 10 does not fall easily.

  Further, in the wall body 10, there may be a gap having variation between the outer wall panels 12 adjacent in the lateral direction due to construction errors. The compressed vertical joint water-stopping member 52 can follow such a dimensional error.

  Further, according to the outer wall joint structure in the first embodiment, as shown in FIG. 3, the water receiving member 54 is disposed so as to surround the vertical joint water-stopping member 52 from the indoor side and the side in a plan view. Therefore, for example, rainwater (W1) that has entered the inside of the sealing material 42 (see FIGS. 1 and 2) and has flowed along the front side of the vertical joint water-stopping member 52 as shown in FIG. Is also suppressed (water stopped) to flow indoors.

Moreover, the rainwater stopped by the water receiving member 54 flows downward along the vertical joint between the outer wall panels 12C and 12D (W2). Furthermore, rainwater can also flow in the lateral direction along the space between the horizontal joint water-stopping member 56 and the sealing material 44 (W3).
Thus, the rainwater (W1) that has flowed through the vertical joint water-stopping member 52 is stopped by the water receiving member 54 at the horizontal joint 30 and hardly flows indoors.

  Moreover, in the outer wall joint structure in the first embodiment, the water receiving member 54 is formed by cutting a sheet-like EPDM into a horseshoe shape. Thus, by integrally molding the water receiving portion 54A and the water guiding portion 54B, the water-stopping property is enhanced as compared with the case where they are separately formed and bonded.

  Further, according to the outer wall joint structure in the first embodiment, as shown in FIG. 2, the outer wall panel 12 is an ALC plate, and is fixed to a building frame (not shown), and the groove portion 14 of one outer wall panel 12A. In contrast, the protrusion 16 of the other outer wall panel 12B is engaged and disposed (so-called real (sane) structure). Thereby, compared with the case where a wall is formed using the outer wall panel which is not provided with the groove part 14 or the protrusion 16, for example, there is no gap in front view and flame-shielding performance is high. Further, by engaging the groove portion 14 and the protrusion 16, it is easy to align the outer wall panels 12A and 12B in the front-rear direction (OUT direction and IN direction).

[Second Embodiment]
In the description of the second embodiment, components having the same configurations as those of the first embodiment are denoted by the same reference numerals and are appropriately omitted.

(Outer wall joint structure)
The outer wall joint structure in the second embodiment is a waterproof structure applied to the vertical joint 21 and the horizontal joint 31 of the outer wall panel 12 constituting the wall body 11 shown in FIG.

  The wall body 11 has a joint structure (horse joint) in which the vertical joint 21 is discontinuous between the upper and lower outer wall panels 12, and the horizontal joint 31 is stopped at the intersection E <b> 2 of the vertical joint 21 and the horizontal joint 31. A sealing material 44 for water is used as a threading material, and a sealing material 42 for water-stopping the vertical joint 21 is abutted and bonded to the sealing material 44.

(Vertical joint)
The configuration of the vertical joint 21 in the second embodiment is the same as the configuration of the vertical joint 20 in the first embodiment as shown in FIG.

(Horizontal joint)
6 shows the structure below the outer wall panels 12A and 12B in FIGS. 2 and 5, that is, the outer wall panel 12F and the inner structure of the horizontal joint 31 in a plan view. FIG. 7 is an exploded perspective view of the outer wall panel 12F, the internal structure of the horizontal joint 31, and the outer wall panel 12B. In FIG. 7, the outer wall panel 12A and the sealing material 42 are not shown.

(Water receiving member)
As shown in FIG. 7, the water receiving member 58 in the horizontal joint 31 is formed with a bottom plate 58C in a portion surrounded by the water receiving portion 58A and the water guiding portion 58B. The bottom plate 58C is a PP (polypropylene) or CR (chloroprene) sheet-like member, which is welded to the water receiving portion 58A and the water guiding portion 58B and bonded to the upper surface of the outer wall panel 12F using butyl tape. .

(Action / Effect)
In the outer wall joint structure in the second embodiment, as shown in FIG. 5, the vertical joint 21 has a discontinuous joint structure between the upper and lower outer wall panels 12. For this reason, the rainwater (W1) which flowed along the vertical joint water stop member 52 between the outer wall panel 12A (not shown) and the outer wall panel 12B shown in FIG. 7 cannot flow downward. For this reason, rainwater temporarily stays in the portion of the water receiving member 58 surrounded by the water receiving portion 58A and the water guiding portion 58B, but a bottom plate 58C is formed in the portion surrounded by the water receiving portion 58A and the water guiding portion 58B. Therefore, the staying rainwater is prevented from flowing more indoors than the water receiver 58A.

  Then, the rainwater flows laterally between the horizontal joint waterproof member 56 and the sealing material 44 (W3), is discharged downward from the end of the outer wall panel 12F (not shown), and finally the wall body 11. It is discharged to the outside from the bottom.

  Thus, in the outer wall joint structure in the second embodiment, by forming the bottom plate 58C on the water receiving member 58, the wall joint 11 in which the vertical joint 21 is discontinuous in the vertical direction as shown in FIG. It can be set as the structure which a water stop performance does not fall easily.

  The outer wall panel 12 in the first and second embodiments may be a part of a pillar. That is, the first outer wall material and the second outer wall material in the present invention refer to all exterior materials used for a vertical surface facing the outdoors.

  In the first and second embodiments, as shown in FIGS. 3 and 6, the water receiving members 54, 58 and the horizontal joint water-stopping member 56 are formed separately, and the horizontal joint water-stopping member 56 is watered. Although it arrange | positions against the receiving members 54 and 58, embodiment of this invention is not restricted to this. For example, the water receiving members 54 and 58 and the horizontal joint water-stopping member 56 may be bonded to each other or integrally formed as one member. In this way, no gap is formed between the water receiving members 54 and 58 and the horizontal joint water-stopping member 56, so that the water-stopping property at the horizontal joint 30 is improved.

  In the first and second embodiments, the outer wall panel 12 is an ALC plate, but the embodiment of the present invention is not limited to this. For example, a material having fire prevention performance such as ECP (extruded cement board) can be used. Since ECP is an unstitched structure, there is little deterioration due to intrusion of rainwater.

  Moreover, in the wall bodies 10 and 11 in 1st, 2nd embodiment, it is not necessary to apply the vertical joint water stop member 52 and the water receiving members 54 and 58 to all the vertical joints and all the horizontal joints. For example, the groove 14 and the ridge 16 may not be formed on an outer wall panel used for a portion joined to an orthogonal wall at the end of the wall 10 or an opening to which a window or an entrance is attached. In such a place, rainwater may be stopped by an irregular sealing material and a backer material arranged inside the irregular sealing material.

  Further, in the first and second embodiments, only the sealing material 42 is disposed in the cutout portions 18 of the vertical joints 20 and 21 shown in FIG. 2, but the embodiment of the present invention is not limited thereto, A backup material may be disposed on the indoor side of the sealing material 42. By disposing the backup material, the water stoppage by the sealing material 42 can be increased.

  Moreover, in 1st, 2nd embodiment, although the vertical joint water stop member 52 shown in FIG. 2 is arrange | positioned between the groove wall 14A and the side wall 16A, embodiment of this invention is not restricted to this, For example, like the vertical joint waterproofing member 53 shown in FIG. 8, you may arrange | position in the state compressed between each side end surface 12E of outer wall panel 12A, 12B.

  Even if the vertical joint waterproof member 53 is arranged in this way, when the outer wall panels 12A, 12B move in a direction away from each other (L direction or R direction in FIG. 8), the compressed vertical joint waterproof member 53 is provided. Since the state which contacted each side end surface 12E of outer wall panel 12A, 12B is maintained by approaching the original state, vertical joint water stop member 53 and each side end surface 12E of outer wall panel 12A, 12B There is no gap between them. Even when the outer wall panels 12A and 12B move in the direction in which the side end surfaces 12E deviate from each other (the IN direction and the OUT direction in FIG. 8), the compressed state of the vertical joint water-stopping member 53 is maintained. It is difficult for a gap to occur between the water stop member 53 and the outer wall panels 12A and 12B.
