FIG.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a building 1 having an exterior wall structure 10 of the present invention.

The building 1 can be, for example, an industrialized house having a steel framework. For industrialized houses, for example, there is a lower structure such as a reinforced concrete foundation, and an upper structure that has a frame structure composed of framework members such as columns and beams, and is provided above the lower structure. and consists of The lower structure is installed on the ground and supports the upper structure. In addition, the frame members that constitute the frame frame can be standardized (standardized) in advance. In that case, they are manufactured in advance at a factory and then brought to the construction site and assembled.

The building 1 is constructed based on predetermined planar modules. A plane module means a basic dimension that serves as a design standard in construction, and the building 1 is constructed so that plane dimensions such as the center-to-center distance between adjacent pillars are integral multiples of the plane module. In other words, the foundation beams of the foundation and the pillars and beams of the upper structure are placed on virtual reference lines (hereinafter simply referred to as "reference lines") arranged in a grid pattern at the same pitch as the planar module in plan view. are arranged so that the central positions of the respective members coincide with each other. The installation reference of the frame supporting the panel members 20 and 30 constituting the exterior wall structure 10 basically coincides with the reference line of the frame (structural members supporting the panel members) based on the plane module.

As shown in FIG. 1, the outer wall structure 10 of the present embodiment that constitutes the outer wall of the building 1 includes a plurality of rectangular plate-like (panel-like) panel members 20 and 30 (outer wall panels) arranged vertically and horizontally. It has Further, the outer wall structure 10 includes a plurality of panel members 20 and 30 having different distances from the installation reference M of the frame supporting the panel members 20 and 30 to the outdoor surfaces of the panel members 20 and 30 . In this example, the plurality of panel members 20 and 30 have a first panel member 20 and a second panel member 30 with different thicknesses. Specifically, the outer wall structure 10 of this example includes a first panel material 20 having a large thickness and a second panel material 30 having a thickness smaller than that of the first panel material 20 . As the first panel member 20 and the second panel member 30 of this example, for example, a lightweight cellular concrete (ALC) panel, a PC concrete panel, an extruded cement board, or the like can be used, but not limited thereto. Note that the panel members 20 and 30 forming the outer wall structure 10 may all have the same thickness. By doing so, the manufacturing and construction management of the panel members 20 and 30 are facilitated. In that case, by arranging the panel materials 20 and 30 so that the distance from the installation reference M of the frame supporting the panel materials 20 and 30 to the indoor surface of the panel materials 20 and 30 is different, the panel The distances to the outdoor surface of the timbers 20, 30 are also arranged differently.

In the outer wall structure 10, the first panel material 20 and the second panel material 30 are attached directly to structural members such as beams that constitute the skeleton of the building 1, or indirectly via connection members, etc., and are attached to the structure. It is supported by members (framework). In addition, the first panel material 20 and the second panel material 30 that constitute the exterior wall structure 10 are determined from the installation reference M (see FIG. 5) of the frame supporting the first panel material 20 and the second panel material 30. , 30 to the rear surfaces 20b, 30b (indoor-side surfaces) (the distances in the thickness direction of the panel materials 20, 30) are constant. In this way, by installing the first panel material 20 and the second panel material 30 at the same distance from the installation reference M of the frame, the mounting structure of the panel materials 20 and 30 to the frame and the indoor side of the panel materials 20 and 30 It becomes difficult to complicate the arrangement of the heat insulating material and the inner wall.

In this example, the back surface 20b (indoor surface) of the first panel member 20 and the back surface 30b (indoor surface) of the second panel member 30 are positioned on the same plane. Therefore, when the first panel member 20 and the second panel member 30 are arranged side by side vertically or horizontally, the outer surface 20a (outdoor surface) of the first panel member 20 is the outer surface of the second panel member 30. It is arranged so as to protrude outward in the thickness direction from the surface 30a (outdoor surface). That is, the outer surface 20a of the first panel member 20 is located outside in the thickness direction by the difference in thickness between the first panel member 20 and the second panel member 30 .

The method of attaching the first panel member 20 and the second panel member 30 to the building frame is not particularly limited. The first panel material 20 and the second panel material 30 can be configured to be indirectly fixed to and supported by the building frame via connection hardware fixed to structural members such as beams.

In the exterior wall structure 10, a joint portion 40 is formed between two panel members 20 and 30 adjacent to each other in the vertical and horizontal directions. 50 is cast.

Here, in the case of the exterior wall structure 10 of this example in which the first panel members 20 and the second panel members 30 having different thicknesses are mixed, the first panel members 20 are arranged adjacent to each other vertically or horizontally as the joint portion 40. A first joint portion 41, a second joint portion 42 where the second panel members 30 are arranged adjacent to each other, and a third joint portion 43 where the first panel member 20 and the second panel member 30 are arranged adjacent to each other. becomes.

2 is an enlarged sectional view showing the first joint portion 41, FIG. 3 is an enlarged sectional view showing the second joint portion 42, and FIG. 4 is an enlarged sectional view showing the third joint portion 43. It is a cross-sectional view shown in FIG.

In this embodiment, in any of the first joint portion 41, the second joint portion 42, and the third joint portion 43, the ceiling 50 is provided from the installation reference M of the frame supporting the panel members 20 and 30 to the ceiling 50. It is constructed such that the distance in the thickness direction to the placement position of is substantially constant. That is, in the outer wall structure 10, regardless of the thickness of the panel members 20 and 30, the placement position of the sealing 50 is substantially constant from the installation reference M in the panel thickness direction in any region of the joint portion 40. ing. Here, the term “substantially constant” is not limited to the case where the distance in the thickness direction from the installation reference M of the frame supporting the panel members 20 and 30 to the placement position of the ceiling 50 is completely the same. It means that the panel member 30 having the smallest thickness among the panel members 20 and 30 constituting the structure 1 has a thickness difference of 10% or less and 10 mm or less. The difference is preferably 5% or less and 5 mm or less, more preferably 1% or less and 1 mm or less.

Sealing pockets 21, which are concave portions for driving sealing 50, are formed in the top, bottom, left, and right end faces 20c (edge faces) of the first panel member 20. As shown in FIG. In this example, the shape of the sealing pocket 21 of the first panel member 20 is the same on all the top, bottom, left, and right end faces 20c, but the shape of the sealing pocket 21 is not limited to this, and can be changed as appropriate.

Similarly, sealing pockets 31 are formed on the top, bottom, left, and right end faces 30c of the second panel member 30. As shown in FIG. In this example, the shape of the sealing pocket 31 of the second panel member 30 is the same on all the top, bottom, left, and right end faces 30c. The shape of the sealing pocket 31 of the second panel material 30 is different from the shape of the sealing pocket 21 of the first panel material 20 .

The sealing pockets 21, 31 of the first panel member 20 and the second panel member 30 extend linearly along the longitudinal direction of the upper, lower, left, and right end faces 20c, 30c. The cross section (the section perpendicular to the longitudinal direction) is constant over the entire length of each end face 20c, 30c. Each sealing pocket 21, 31 is formed of a notch-like concave portion that opens to the outer surfaces 20a, 30a and the end faces 20c, 30c of the panel members 20, 30, respectively.

The sealing pockets 21, 31 extend from the outer surfaces 20a, 30a of the panel materials 20, 30 toward the back surfaces 20b, 30b and terminate at intermediate portions in the thickness direction.

As shown in FIGS. 2 and 4, the sealing pocket 21 of the first panel member 20 has an obliquely inclined bottom surface 21a, and the depth of the sealing pocket 21 gradually increases toward the opposing panel members 20 and 30. is configured to be With such a configuration, the thickness of the sealing 50 can be sufficiently secured even when the sealing 50 is arranged adjacent to the second panel member 30 having a small thickness as shown in FIG. As a result, even at the joint portion 43 between the panel members 20 and 30 having different thicknesses, deterioration of the sealing performance can be more reliably suppressed. The bottom surface 31 a of the sealing pocket 31 of the second panel member 30 is parallel to the outer surface 30 a and the back surface 30 b of the second panel member 30 . The shape of each sealing pocket 21 is not limited to the illustrated example, and can be changed as appropriate.

As shown in FIG. 4, the distance (depth) D1 from the outer surface 20a of the first panel member 20 to the deepest portion 21b of the bottom surface 21a of the sealing pocket 21 is equal to the distance (depth) D1 from the outer surface 30a of the second panel member 30 to the sealing pocket. 31 to the deepest portion 31b (depth) D2.

Figures 5 and 6 each show an example of an external floor 60 connection projecting from an external wall, such as a veranda, roof balcony or the like. The external floor 60 protrudes outward from the outer surfaces 20a, 30a of the panel members 20, 30 in the exterior wall structure 10 and extends in the horizontal direction.

The external floor 60 shown in FIG. 5 includes a floor panel member 61 made of an ALC panel or the like, a panel member 62 placed over the upper surface of the floor panel member 61, and an upper portion of the panel member 62 (the outermost layer of the external floor 60). It has a waterproof layer 63 provided on.

The waterproof layer 63 includes a substantially flat bottom portion 63a and rising portions 63b that protrude upward from the outer edge of the bottom portion 63a. In this example, the upper end 63c of the rising portion 63b on the outer wall side (on the side of the panel members 20, 30) of the waterproof layer 63 is formed by the first panel member 20 having a large thickness and the second panel member 30 having a small thickness, which are vertically adjacent to each other. It is arranged in the joint part 40 (the third joint part 43) between. A seal 50 is cast in the joint portion 40 so as to cover the upper end 63c of the rising portion 63b.

Here, in FIG. 5, the distance from the installation reference M of the beam 64 constituting the frame to the placement position of the sealing 50 in the joint portion 40 (the first joint portion 41, the second joint portion 42, and the third joint portion 43) The distance L1 (the distance in the thickness direction of the panel materials 20 and 30) is substantially constant regardless of the thickness of the panel materials 20 and 30. As shown in FIG.

The first panel member 20 is attached to a connection member 65 fixed to the top surface of the beam 64 . The connection member 65 of this example has a horizontal plate portion 65a and a vertical plate portion 65b. The first panel member 20 is supported from below by being placed on the upper surface of the horizontal plate portion 65a of the connection member 65, and is supported from the indoor side by the vertical plate portion 65b that contacts the back surface 20b of the first panel member 20. be.

The second panel material 30 of this example functions as a waterproof base material. The second panel material 30 is placed on the upper surface of the floor panel material 61 and connected to the beams 64 via the connecting members 66 . The connection members 65 and 66 may be members formed by bending metal plates or joining them by welding or the like, but the connection members 65 and 66 are not limited to this. Alternatively, the panels 20 , 30 may be attached directly to the beams 64 .

Although not particularly limited, the waterproof layer 63 includes, for example, a waterproof steel plate as a metal plate material formed by bending or the like, and a waterproof sheet attached to the surface along the shape of the waterproof steel plate. can be formed with

In this example, the end portion of the waterproof steel plate forming the upper end 63c of the rising portion 63b on the outer wall side of the waterproof layer 63 is the joint bottom of the third joint portion 43 between the first panel member 20 and the second panel member 30. A sealing 50 is placed in the third joint portion 43 so as to cover the upper end 63c from the outside.

As shown in FIG. 5, the upper end 63c of the rising portion 63b of the waterproof layer 63 is arranged in the joint portion 40 between the vertically adjacent panel members 20 and 30, so that the thickness of the panel members 20 and 30 is reduced. The difference does not affect the position of the upper end 63c of the rising portion 63b of the waterproof layer 63. FIG. As a result, the members constituting the waterproof layer 63 do not have a complicated shape, and the shape can be made simple, and workability can be improved. Moreover, since it is not necessary to cut and engrave the outer surfaces 20a, 30a of the panel members 20, 30 in order to arrange the upper end 63c of the rising portion 63b of the waterproof layer 63, construction is further facilitated.

The external floor 70 shown in FIG. 6 includes a floor panel member 71 made of an ALC panel or the like, a panel member 72 placed over the upper surface of the floor panel member 71, and an upper portion of the panel member 72 (outermost layer of the external floor 70). It has a waterproof layer 73 provided on. The floor panel member 71 of this example is arranged so as to abut against the outer surface 30a of the second panel member 30, but is not limited to this. , 30 (downward end surfaces 20c, 30c) from below.

As shown in FIG. 6, the first panel member 20 that constitutes the outer wall is attached to a connecting member 75 fixed to the upper surface of the beam 74 . Note that the first panel material 20 having a greater thickness than the second panel material 30 may be used instead of the second panel material 30 shown in FIG. In this case, the carving depth D3 (the depth from the outer surface 20a) of the recess 32 provided in the outer surface 20a of the first panel member 20 is larger than that of the second panel member 30 by the thickness.

The waterproof layer 73 includes a bottom portion 73a and rising portions 73b that protrude upward from the outer edge of the bottom portion 73a. In this example, the upper end 73c of the rising portion 73b on the outer wall side (on the side of the panel members 20 and 30) is arranged in the middle portion of the second panel member 30 in the vertical direction. Specifically, the upper end 73c of the rising portion 73b is arranged in a horizontal recess 32 (groove) formed in the outer surface 30a of the second panel member 30, and the upper end 73c of the rising portion 73b is positioned in the recess 32. A sealing 50 is cast so as to cover it. The engraving depth D3 from the outer surface 30 a of the second panel material 30 to the recess 32 is the same as the depth D2 of the sealing pocket 31 of the second panel material 30 . When the recess 32 is formed in the outer surface 20a of the first panel material 20, the depth D3 of engraving from the outer surface 20a is the same as the depth D1 of the sealing pocket 21 of the first panel material 20.

Here, in FIG. 6, the distance in the thickness direction of the panel materials 20, 30 from the installation reference M of the beam 74 that constitutes the frame to the placement position of the ceiling 50 in the recess 32 where the upper end 73c of the rising portion 73b is arranged L2 is substantially constant regardless of the thickness of the panel members 20 and 30. Further, the distance L2 is the same as the distance L1 to the placement position of the sealing 50 in the joint 40 (the first joint 41, the second joint 42 and the third joint 43) between the panel members 20 and 30. is.

Thus, in this example, in the thickness direction of the panel members 20 and 30, the placement position of the sealing 50 in the recess 32 where the upper end 73c of the rising portion 73b of the waterproof layer 73 is arranged is between the panel members 20 and 30. It matches the placement position of the joint portion 40 . With such a configuration, there is no difference in level between the sealings 50, so the shape of the member that constitutes the rising portion 73b of the waterproof layer 73 can be simplified. In addition, since there is no step between the ceilings 50 and the shape of the member constituting the rising portion 73b is simplified, the surface where the ceiling is placed does not move in and out, and workability is improved.

Figures 7 and 8 show examples of eaves 80 and 90, respectively, protruding from the outer wall. The eaves 80, 90 protrude outward from the outer surfaces 20a, 30a of the panel members 20, 30 in the outer wall structure 10 and extend in the horizontal direction.

The eaves section 80 shown in FIG. 7 includes eaves slabs 81 connected via connecting members 85 to beams 84 that constitute the frame. Further, the outer surface 20a of the first panel member 20 on which the eaves 80 is provided is provided with a notch 23 into which the eaves slab 81 can be inserted. The depth D4 of the notch 23 is formed according to the surface of the sealing 50 of the joint portion 40 between the panel members 20 and 30 regardless of the thickness of the panel members 20 and 30 . That is, the distance L3 in the thickness direction of the panel materials 20, 30 from the installation reference M of the beam 84 constituting the frame to the bottom surface 23a of the notch 23 is substantially constant regardless of the thickness of the panel materials 20, 30. be. Further, the distance L3 is approximately the distance L1 to the placement position of the sealing 50 in the joint portion 40 (the first joint portion 41, the second joint portion 42 and the third joint portion 43) between the panel members 20 and 30. constant.

In this example, by arranging the eaves slab 81 so as to be inserted into the notch 23, the gap between the wall parting part of the eaves part 80 and the outer wall (the outer surface 20a of the first panel member 20 and the eaves slab 81) can be eliminated, the members of the eaves 80 can be simplified, the design can be improved, and the workability of the eaves 80 can be improved.

In addition, in the eaves part 80, by providing the notch 23 in the outer surface 20a of the first panel member 20, the second panel member 30 having a small thickness is arranged adjacent to the left and right of the first panel member 20. However, the shape of the end portion of the eaves slab 81 can be accommodated in a straight line. Therefore, it is possible to simplify the shape of the eaves slab 81, improve the design, and improve the workability.

The eaves part 90 shown in FIG. 8 shows the case where the outer surfaces 20a, 30a of the panel materials 20, 30 are not provided with the cutouts 23. As shown in FIG. The eaves section 90 includes an eaves slab 91 connected via a connection member 95 to a beam 94 that constitutes the building frame.

In the case of this example, especially in the joint portion 40 between the panel members 20 and 30, a gap is likely to be formed between the end portion of the eaves slab 91 and the surface of the joint portion 40 on which the sealing 50 is placed. It is preferable to dispose a parting material (decorative member) that fills the gap. That is, it is preferable that the parting material corresponding to the surface shape of the outer wall is arranged in the portion where the eaves 90 protruding from the outer wall is provided. According to this, the unevenness corresponding to the shape of the outer surfaces 20a, 30a of the panel members 20, 30 in the eaves part 90 and the gap between the eaves slab 91 can be made inconspicuous, and the design can be improved. can be done.

As described above, in the outer wall structure 10 of the present embodiment, the sealing 50 of the joint portion 40 is placed at a substantially constant thickness direction distance from the installation reference M regardless of the thickness of the panel members 20 and 30. It is configured to be As described above, since the placement position of the sealing 50 is aligned regardless of the thickness of the panel materials 20 and 30, the installation (placement) of the sealing 50 of the joint portion 40 is facilitated, and workability is improved. In addition, even between the panel materials 20 and 30 having different thicknesses, no step is formed on the surface where the sealing 50 is placed, so deterioration of the appearance design and deterioration of the sealing performance (waterproof performance) can be suppressed. Furthermore, since no step is formed on the surface on which the sealing 50 is placed, it is possible to secure the sealing performance while suppressing the amount of the sealing 50 to be placed and reducing the cost.

Further, in the exterior wall structure 10 of the present embodiment, as shown in FIG. A protruding portion (exposed portion 20d) of the end face 20c (edge face) of the material 20 facing the second panel member 30 is exposed to the outside (see FIG. 4). By protruding a portion (exposed portion 20d) of the end surface 20c of the first panel member 20 and making it visible from the outside in this way, the thickness of the first panel member 20 is expressed, and the exterior wall structure 10 is made to have a heavy weight. It can give a sense of quality and luxury, and enhance the design.

As described above, according to the exterior wall structure 10 of the present embodiment, by arranging the panel materials 20 and 30 having different thicknesses side by side, the design is enhanced, the construction of the sealing 50 of the joint portion 40 is facilitated, and It is also possible to suppress deterioration in designability and sealing performance.

The internal corner wall structure according to the present invention is not limited to the configuration of the embodiment described above, and can be realized by various configurations without departing from the scope of the claims. . For example, although the exterior wall structure 10 including two types of panel members 20 and 30 having different thicknesses has been described in the above embodiment, it may be configured to include three or more types of panel members having different thicknesses. In the above embodiment, the back surfaces 20b and 30b of the panel members 20 and 30 are all arranged on the same plane. The positions of the back surfaces 20b and 30b of the panel members 20 and 30 may be shifted in the thickness direction of the panel members 20 and 30, as long as they are arranged in such a manner.
