  Hereinafter, modes for carrying out the present invention will be described.

(First embodiment)
An example of the first embodiment is shown in FIG. The joint structure of the outer wall material is formed by including the outer wall material 1 disposed adjacent to each other, the joint 3 formed between the end faces 2 of the outer wall material 1, and the joint material 4 disposed in the joint 3 There is.

  The outer wall material 1 is a so-called siding material, and can be exemplified as a ceramic-based siding material which is a cured product of a molding material containing cement. The outer wall material 1 may be a metal siding material, a resin siding material, or the like. The surface of the outer wall material 1 is provided with a concavo-convex pattern such as brick tone, wood grain tone and stone tone, and makeup by printing or painting. As shown in FIG. 2, the outer wall material 1 is formed in, for example, a rectangular flat plate shape. A receiving portion 11 is provided at the upper end of the outer wall material 1. The thickness of the receiving portion 11 is thinner than the thickness of the central portion of the outer wall material 1. The receiving portion 11 is formed biased to the back surface side in the thickness direction of the outer wall material 1. The receiving portion 11 is provided over the entire length of the outer wall material 1 in the lateral direction. In addition, an overlapping portion 15 is formed at the lower end of the outer wall material 1. The thickness of the overlapping portion 15 is thinner than the thickness of the central portion of the outer wall material 1. The overlapping portion 15 is formed to be biased to the surface side in the thickness direction of the outer wall material 1. The overlapping portion 15 is provided over the entire length of the outer wall material 1 in the lateral direction. On the rear side of the overlapping portion 15, a protrusion 13 is provided at the lower end of the outer wall material 1. The lower end surface of the projection 13 is located above the lower end surface of the overlapping portion 15. The protrusion 13 is provided over the entire length in the lateral direction of the outer wall material 1. The end surface 2 of the outer wall material 1 is a side end surface (lateral end surface) of the outer wall material 1. The end face 2 is formed to be flat over the entire length in the longitudinal direction of the outer wall material 1.

  The joint 3 is formed between the end faces 2 of the outer wall material 1 adjacent in the lateral direction. The width dimension of the joint 3 (the dimension between the facing end surfaces 2) can be 3 to 15 mm, but is not limited thereto. The joint 3 is formed over the entire length in the longitudinal direction of the outer wall material 1.

  As shown in FIG. 3, the joint material 4 is made of metal, and is formed, for example, by bending a metal plate. The joint material 4 preferably has high corrosion resistance, and is formed of, for example, a gal barium steel plate (registered trademark), an aluminum material, a fluorocarbon resin-based coated steel plate, or the like. The joint material 4 is formed to be long in the longitudinal direction, and the longitudinal dimension of the joint material 4 is preferably equivalent to the longitudinal dimension of the joint 3 or longer than the longitudinal dimension of the joint 3. The thickness (plate thickness) of the joint material 4 is preferably 0.3 to 2 mm, but is not limited thereto.

  The joint material 4 includes a closed portion 40, a support portion 41 and a fixing portion 42. The closing portion 40 closes the opening 30 of the joint 3. Accordingly, the width dimension (lateral dimension) of the closed portion 40 is formed to be the same as or slightly larger than the width dimension of the joint 3. The closed portion 40 is formed over the entire length of the joint material 4. The support portion 41 is provided at the lateral end of the blocking portion 40. The support portion 41 is formed to project rearward (rear surface side) of the closed portion 40. The support portion 41 is formed over the entire length of the joint material 4. One support portion 41 is provided at each of both lateral ends of the closing portion 40. The two support portions 41 are formed to face each other. The outer surface of each support portion 41 is formed as a contact portion 43. An angle (a recess angle) between each support portion 41 and the closing portion 40 is formed at an acute angle. It is preferable that the angles θ1 and θ2 between the support portion 41 and the blocking portion 40 be 60 to 85 °. When the angles θ1 and θ2 are less than 60 °, the blocking portion 40 is difficult to be supported by the support portion 41, and the joint material 4 is easily deformed. In addition, the width of the blocking portion 40 becomes too wide. When the angles θ1 and θ2 are larger than 85 °, the support portion 41 easily contacts the end face 2 of the outer wall material 1 at the surface, and the joint material 4 is attached to the edge 14 (surface side edge 12) of the outer wall material 1 It becomes difficult to make line contact. The angles θ1 and θ2 may be the same or different. The fixing portion 42 is provided at the rear end of the support portion 41 (the end not connected to the closing portion 40). The fixing portion 42 is formed in each of the support portions 41 one by one. The fixing portion 42 is formed over the entire length of the joint material 4. The tip of the fixing portion 42 (the end portion not connected to the support portion 41) protrudes outward (laterally) from the closing portion 40. The fixing portion 42 is formed to be parallel to the closing portion 40.

  FIG. 4 shows an outer wall provided with the outer wall material 1 and the joint material 4 described above.

  The outer wall material 1 is attached to the wall base 5 by a fastener 6. The wall base 5 is formed to include a waterproof wall 51 and a support 52. The waterproof wall 51 is formed by stacking concrete or many bricks, blocks and stones. The waterproof wall 51 has a high waterproof performance, and is formed so that almost no rainwater passes from the front surface (outside surface) to the back surface (interior surface). The support 52 is provided on the surface side (outdoor side) of the waterproof wall 51. As shown in FIG. 4C, the support 52 includes, for example, a plurality of vertical supports 520 and a fixed support 521. The longitudinal support 520 is formed to be long in the longitudinal direction. One end of the fixed support 521 is provided so as to protrude from the back of the vertical support 520. The other end of the fixed support 521 is fixed to the waterproof wall 51, whereby the support 52 is fixed to the prevention wall 51. The vertical support 520 and the fixed support 521 are made of metal such as steel, and examples thereof include a circular pipe, a square pipe, an L-shaped steel, a C-shaped steel, an H-shaped steel, a T-shaped steel, and a Z-shaped steel. In FIG. 1, the vertical support 520 is formed in a hat-like shape in cross section, and a mounting plate 522 is provided on the surface of the vertical support 520.

  The fastener 6 is made of metal such as stainless steel and, as shown in FIG. 5, is formed of a fixing plate 60, a mounting piece 61, an upward piece 62, a downward piece 63, and an abutting portion 64. The fixing plate 60 is formed in a flat plate shape, and a fixing hole 66 penetrating in the thickness direction is provided. The mounting piece 61 is formed to horizontally project forward at a longitudinal center of the fixing plate 60. The upward piece 62 is formed to project upward from the tip of the mounting piece 61. The upward piece 62 is provided over substantially the entire lateral length of the fastener 6. The downward piece 63 is formed to project downward from the tip of the mounting piece 61. Two downward pieces 63 are provided side by side in the lateral direction of the fastener 6. The abutments 64 are provided at both side ends of the fixing plate 60. The front surface of the contact portion 64 is located forward of the front surface of the fixing plate 60. Further, the front surface of the contact portion 64 is located rearward of the upward piece 62 and the downward piece 63.

  In the outer wall shown in FIGS. 1, 4A and 4B, the joint material 4 is attached to the surface of the vertical support 520. In this case, the fixing portion 42 of the joint material 4 is fixed to the vertical support 520 by a fixing tool such as a screw or a rivet or fixed by welding or the like. The joint material 4 is disposed long along the longitudinal direction of the longitudinal support 520. Further, the fastener 6 is attached to the vertical support 520 after the joint material 4 is attached. If there is a mounting plate 522, the fastener 6 is attached to the longitudinal support 520 via the mounting plate 522. In this case, two fasteners 6 are attached side by side so as to sandwich the joint material 4. Also, a plurality of fasteners 6 are attached side by side in the longitudinal direction. The distance between the longitudinally aligned fasteners 6 is substantially the same as the height dimension of the outer wall material 1. The side end of the joint 6 on the joint material 4 side is disposed on the surface of the fixing portion 42. The fasteners 6 are fixed by driving fasteners such as screws and rivets from the fixing holes 66 into the vertical support 520.

  Then, the plurality of outer wall materials 1 are fixed to the vertical support 520 by the fasteners 6 to form the outer wall. In this case, the receiving portion 11 of the outer wall material 1 disposed below the fastener 6 is hooked to the downward piece 63 of the fastener 6. Further, the projection 13 of the outer wall material 1 disposed on the upper side of the fastener 6 is placed on the mounting piece 61 of the fastener 6, and the projection 13 is hooked on the upward piece 62 of the fastener 6. In addition, the overlapping portion 15 of the upper outer wall material 1 is disposed on the surface side (front side) of the receiving portion 11 of the lower outer wall material 1. Thus, a plurality of outer wall materials 1 are attached side by side in the longitudinal direction.

  Also, a plurality of outer wall materials 1 are attached side by side in the lateral direction. In this case, the back surface of the outer wall material 1 contacts the front surface of the contact portion 64 of the fastener 6. Further, the outer wall members 1 adjacent in the lateral direction are arranged such that the end faces (side end faces) 2 face each other. Between the opposing end faces 2 is formed as a joint (longitudinal joint) 3. In the joint 3, the closed portion 40 and the support portion 41 of the joint material 4 are disposed. The blocking portion 40 is disposed so as to protrude from the opening 30 of the joint 3 to the outside of the joint 3. The blocking portion 40 protrudes about 2 mm from the joint 3. And the outer surface of the support part 41 which is the contact part 43 of the joint material 4 and the edge 14 of the outer wall material 1 are substantially in line contact. 1, the outer surface (contact portion 43) of the support portion 41 of the joint material 4 and the surface side edge 12 of the outer wall material 1 (the opening edge portion of the joint 3 and the corner portion on the surface side of the outer wall material 1) And are in line contact with each other. Here, the substantially linear contact may be not only in the case of accurate linear contact but also in discontinuous contact. That is, the substantially line contact means a state in which the outer surface of the support portion 41 and the edge 14 of the outer wall material 1 are not in plane contact with each other. The contact portion 43 of the joint material 4 and the surface side edge 12 of the outer wall material 1 make a substantially line contact along the longitudinal direction (longitudinal direction) of the joint 3 over the entire length of the joint 3. Of the two contact portions 43, one of the contact portions 43 is substantially in line contact with the surface side edge 12 of one of the outer wall members 1 of the outer wall members 1 adjacent in the lateral direction. The other contact portion 43 substantially contacts the surface side edge 12 of the other outer wall material 1 of the outer wall materials 1 adjacent in the lateral direction. Thus, the bonded structure of the outer wall material of the present embodiment is formed.

  In the present embodiment, the outer wall material 1 disposed adjacent to each other, the joint 3 formed between the end faces 2 of the outer wall material 1, and the joint material 4 disposed in the joint 3 are provided. The joint material 4 is made of metal and includes a contact portion 43. Further, the contact portion 43 is substantially in line contact with the surface side edge 12 of the outer wall material 1 along the joint 3. Thereby, in the present embodiment, since the joint material 4 is made of metal, deterioration with age can be less than that of a resin-made sealing material, and breakage of the joint material 4 hardly occurs. Moreover, since the joint material 4 is in approximate line contact with the surface-side edge 12 of the outer wall material 1 by the contact portion 43, rainwater is brought to the joint 3 by surface tension, capillary phenomenon, etc. It becomes easy to control staying. In addition, when the outer wall is viewed from the surface side, a gap is unlikely to be generated between the surface-side end edge 12 of the outer wall material 1 and the closed portion 40 of the joint material 4. Therefore, in the present embodiment, the waterproof performance and the designability of the outer wall are unlikely to be reduced. In the present embodiment, since the waterproof wall 51 is formed on the indoor side of the outer wall material 1, the waterproof property of the outer wall can be secured by the prevention wall 51.

  Further, in the present embodiment, the joint material 4 includes the closing portion 40 closing the opening 30 of the joint 3 and the support portion 41 projecting from the end of the closing portion 40 to the back surface side of the closing portion 40. In addition, the corner between the blocking portion 40 and the support portion 41 is formed at an acute angle. In addition, the outer surface portion of the support portion 41 functions as the contact portion 43. As a result, the support portion 41 of the joint material 4 is less likely to be in surface contact with the edge 14 of the outer wall material 1, and the contact portion 43 is more likely to substantially contact with the edge 14 of the outer wall material 1. Designability is unlikely to be impaired.

  The fastener 6 may be a long one as well as the short one as shown in FIG. As shown in FIG. 6, the long fastener 6 is a fixing plate 60 formed in a horizontally long shape, an abutting portion 64 provided forwardly projecting on the upper end of the fixing plate 60, and a front end on the lower end of the fixing plate 60. It has an upward piece 62 and a downward piece 63 which are provided to protrude. In the fixing plate 60, a plurality of fixing holes 66 penetrating in the thickness direction are formed side by side in the lateral direction. The upward pieces 62 and the downward pieces 63 are alternately arranged in the lateral direction. The upward piece 62 is formed to project upward. The downward piece 63 is formed to project downward.

  The long fasteners 6 are disposed between adjacent joint materials 4. The fasteners 6 are fixed by driving fasteners such as screws and rivets from the fixing holes 66 to the vertical support 520 of the wall base 5. If there is a mounting plate 522, the fastener 6 is attached to the longitudinal support 520 via the mounting plate 522. The outer wall material 1 disposed on the lower side of the fastener 6 is hooked to the downward piece 63 of the fastener 6 with the receiving portion 11 thereof. Further, the projection 13 of the outer wall material 1 disposed on the upper side of the fastener 6 is placed on the mounting piece 61 of the fastener 6, and the projection 13 is hooked on the upward piece 62 of the fastener 6. In addition, the overlapping portion 15 of the upper outer wall material 1 is disposed on the surface side (front side) of the receiving portion 11 of the lower outer wall material 1. Thus, a plurality of outer wall materials 1 are attached side by side in the longitudinal direction.

  The long fastener 6 can be attached to the wall base 5 while holding the outer wall material 1 over substantially the entire length in the lateral direction. Therefore, the long fastener 6 can attach the outer wall material 1 to the wall base 5 more firmly than the short fastener 6. The long fastener 6 is preferably applied to the outer wall material 1 attached to the high rise of the building. Further, in addition to being attached to the wall base 5 with the long fastener 6, it is preferable that the high-rise outer wall material 1 of the building is also fixed to the wall base 5 by fasteners such as screws and rivets.

Second Embodiment
An example of the second embodiment is shown in FIG. The joint structure of the outer wall material is different from the first embodiment in the shape of the joint material 4 and the contact structure of the contact portion 43 and the outer wall material 1.

  The joint structure of the outer wall material is formed by including the outer wall material 1 disposed adjacent to each other, the joint 3 formed between the end faces 2 of the outer wall material 1, and the joint material 4 disposed in the joint 3 There is.

  The outer wall material 1 and its end face 2 and joint 3 are formed in the same manner as in the first embodiment. The joint material 4 is formed in the same manner as the first embodiment except for the shape thereof.

  As shown in FIG. 8, the joint material 4 includes a closed portion 40, a support portion 41 and a fixing portion 42. The closing portion 40 closes the opening 30 of the joint 3. Accordingly, the width dimension (lateral dimension) of the closed portion 40 is formed to be the same as the width dimension of the joint 3. The closed portion 40 is formed over the entire length of the joint material 4. The support portion 41 is provided at the lateral end of the blocking portion 40. The support portion 41 is formed to project rearward (rear surface side) of the closed portion 40. The support portion 41 is formed over the entire length of the joint material 4. One support portion 41 is provided at each of both lateral ends of the closing portion 40. The two support portions 41 are formed to face each other. The boundary between each support portion 41 and the blocking portion 40 is formed as a contact portion 43. The contact portion 43 is formed linearly over the entire length of the joint material 4. An angle (a recess angle) between each support portion 41 and the closing portion 40 is formed at an acute angle. It is preferable that the angles θ1 and θ2 between the support portion 41 and the blocking portion 40 be 60 to 85 °. When the angles θ1 and θ2 are less than 60 °, the blocking portion 40 is difficult to be supported by the support portion 41, and the joint material 4 is easily deformed. In addition, the width of the blocking portion 40 becomes too wide. When the angles θ1 and θ2 become larger than 85 °, the support portion 41 easily contacts the end face 2 of the outer wall material 1 and the joint material 4 hardly contacts the end face 2 in line. The angles θ1 and θ2 may be the same or different. The fixing portion 42 is provided at the rear end of the support portion 41 (the end not connected to the closing portion 40). The fixing portion 42 is formed in each of the support portions 41 one by one. The fixing portion 42 is formed over the entire length of the joint material 4. The tip of the fixing portion 42 (the end portion not connected to the support portion 41) protrudes outward (laterally) from the closing portion 40. The fixing portion 42 is formed to be parallel to the closing portion 40. The joint material 4 in the second embodiment is formed to have a smaller size between the closed portion 40 and the fixed portion 42 than the joint material 4 in the first embodiment.

  The outer wall material 1 is attached to the wall base 5 by a fastener 6. The wall base 5 and the fastener 6 are formed in the same manner as in the first embodiment. Also, the fastener 6 and the joint material 4 are attached to the wall base 5 in the same manner as in the first embodiment. Further, in the same manner as in the first embodiment, the outer wall material 1 is attached to the vertical support 520 by the fastener 6 to form the outer wall.

  The plurality of outer wall materials 1 are attached side by side in the lateral direction. In this case, the back surface of the outer wall material 1 contacts the front surface of the contact portion 64 of the fastener 6. Further, the outer wall members 1 adjacent in the lateral direction are arranged such that the end faces (side end faces) 2 face each other. Between the opposing end faces 2 is formed as a joint (longitudinal joint) 3. In the joint 3, the closed portion 40 and the support portion 41 of the joint material 4 are disposed. The blocking portion 40 is disposed so as not to protrude from the opening 30 of the joint 3 to the outside of the joint 3. And the contact part 43 of the joint material 4 is substantially in line contact with the edge 14 of the outer wall material 1. In FIG. 7, the contact portion 43 of the joint material 4 and the end face 2 of the joint 3 of the outer wall material 1 are in substantially line contact with each other. The contact portion 43 of the joint material 4 and the end face 2 of the outer wall material 1 make a substantially line contact along the longitudinal direction (longitudinal direction) of the joint 3 over the entire length of the joint 3. Of the two contact portions 43, one of the contact portions 43 is substantially in line contact with the end face 2 of one of the outer wall members 1 of the outer wall members 1 adjacent in the lateral direction. The other contact portion 43 substantially contacts the end face 2 of the other outer wall material 1 of the outer wall materials 1 adjacent in the lateral direction. Thus, the bonded structure of the outer wall material of the present embodiment is formed.

  In this embodiment, as in the first embodiment, the outer wall material 1 disposed adjacent to each other, the joint 3 formed between the end faces 2 of the outer wall material 1, and the joint material 4 disposed in the joint 3 And The joint material 4 is made of metal and includes a contact portion 43. Further, the contact portion 43 is substantially in line contact with the opening edge portion of the joint 3 which is the edge 14 of the outer wall material 1, that is, the end face 2 along the joint 3. Thereby, in the present embodiment, since the joint material 4 is made of metal, deterioration with age can be less than that of a resin-made sealing material, and breakage of the joint material 4 hardly occurs. Moreover, since the joint material 4 is in line contact with the edge 14 of the outer wall material 1 by the contact portion 43, rainwater infiltrates from the joint 3 due to surface tension, capillary phenomenon, etc. as compared with the case of contact on the surface. It becomes difficult. Further, when viewed from the surface side of the outer wall, a gap does not easily occur between the end face 2 of the outer wall material 1 and the closed portion 40. Therefore, in the present embodiment, the waterproof performance of the outer wall is less likely to be degraded, and the designability is less likely to be degraded. In the present embodiment, since the waterproof wall 51 is formed on the indoor side of the outer wall material 1, the waterproof property of the outer wall can be secured by the prevention wall 51.

  Further, in the present embodiment, the joint material 4 includes the closed portion 40 which closes the opening 30 of the joint 3 and the support portion 41 which protrudes from the end of the closed portion 40 to the back surface side of the closed portion 40. Further, the corner between the blocking portion 40 and the support portion 41 is formed at an acute angle. Further, the boundary between the blocking portion 40 and the support portion 41 functions as the contact portion 43. As a result, the support portion 41 of the joint material 4 is less likely to be in surface contact with the edge 14 of the outer wall material 1, the contact portion 43 is more likely to substantially contact with the edge 14 of the outer wall material 1, and the waterproofness of the outer wall is improved. Hard to lose.

  As shown in FIG. 10, the joint material 4 includes a closed portion 40, a support portion 41, and a fixing portion 42. The closing portion 40 closes the edge 14 of the outer wall material 1 and the opening 30 of the joint 3. Accordingly, the width dimension (lateral dimension) of the closing portion 40 is formed larger than the width dimension of the joint 3. The closed portion 40 is formed over the entire length of the joint material 4. Folded portions 44 are provided at both ends of the blocking portion 40. The folded back portion 44 is formed to be folded back to the back surface side of the closed portion 40 from each of both ends of the closed portion 40. The folded back portion 44 is formed over the entire length of the joint material 4. The boundary between the blocking portion 40 and the folded back portion 44 is formed as a projecting portion 45. The projecting portions 45 are formed to project rearward from both ends of the closing portion 40. The protrusion 45 is formed over the entire length of the joint material 4. The tip of the projecting portion 45 is formed at an acute angle, and the tip is formed as a contact portion 43. The contact portion 43 is formed linearly over the entire length of the joint material 4. The support portion 41 is provided at the end of the folded back portion 44 (the end not connected to the closed portion 40). The support portion 41 is formed to project rearward of the folded portion 44. The support portion 41 is formed over the entire length of the joint material 4.
