Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIGS. 1, 2, and 3, in the outer wall structure according to this embodiment, the vertical joint formed between the small openings (left and right side portions) 1 a of the outer wall panel 1 adjacent to the left and right, The joint cover 2A according to this embodiment is attached. The outer wall panel 1 is composed of a sandwich panel in which a heat insulating material 11 as a core material made of foamed plastic or the like is sandwiched between an indoor metal plate 12 and an outdoor metal plate 13. In the small edge 1a of the outer wall panel 1 made of this sandwich panel, the heat insulating material 11 is exposed. Moreover, the said outer wall panel 1 is fixed to the trunk edge 3 which consists of channel steel, for example using the drill screw 31. FIG. In addition, the said heat insulating material 11 may have other characteristics, such as fire resistance.

  Further, uneven portions are formed at the upper end portion and the lower end portion of the outer wall panel 1. As for the outer wall panel 1 arrange | positioned up and down, the movement of the direction orthogonal to an outer wall surface is controlled by fitting the said uneven | corrugated | grooved part mutually. Further, the head of the drill screw 31 screwed into the upper end side of the lower outer wall panel 1 is hidden on the lower end side of the upper outer wall panel 1 by the fitting of the unevenness.

  The joint cover 2 </ b> A is inserted into the joint and has a locking member 21 a having a locking piece portion 21 a that is locked to each small opening 1 a, and is positioned on the outdoor side of the locking member 21 to cover the joint. A main body member 22. The locking member 21 and the main body member 22 are made of metal, for example.

  Further, as shown in FIG. 4A, the locking member 21 and the main body member 22 have surface portions 21b and 22a that are orthogonal to the depth direction of the joint, and the both surface portions 21b and 22a are screws. 24 is fixed. The screw 24 is screwed into the through hole 21e of the surface portion 21b of the locking member 21, and is inserted into an insertion hole (not shown) formed in the surface portion 22a of the main body member 22. For example, a rubber packing may be provided between the head of the screw 24 and the surface portion 22 a of the main body member 22.

  The locking member 21 has a length of about 50 mm, for example, and the width of the surface portion 21b of the locking member 21 is about 25 mm, for example. The main body member 22 has a length of about 1030 mm in consideration of the area of the joint portion, for example, because the length of the outer wall panel 1 is about 1000 mm. Of course, these dimensions are examples and are not limited to such dimensions. Further, for example, four locking members 21 are provided on the main body member 22, but the number is not limited thereto.

  As shown in FIG. 4B, the locking member 21 has a concave portion 21c in which the surface portion 21b is formed on the outdoor side and the indoor side is opened. The locking piece portion 21a is formed by obliquely bending a portion extending from the side plate portion forming the concave portion 21c. Further, the stopper member 21 is formed with four stopper portions 21 d for preventing rotation with respect to the main body member 22. In the stopper portion 21d, for example, a part of the side plate portion forming the concave portion 21c (a portion on the side opposite to the side on which the locking piece portion 21a is formed) protrudes in a direction orthogonal to the surface portion 21b. It is formed by cutting and bending a single plate. Further, the side plate portion forming the concave portion 21c is formed substantially orthogonal to the surface portion 21b.

  Further, the locking member 21 has elasticity, and the distance between the distal end portions of the locking piece portions 21a in the natural state is wider than the width of the joint and gradually increases toward the outdoor side. It is formed as follows. And the space | interval of the front-end | tip part of the said locking piece part 21a becomes narrow at the time of the insertion to the said joint, and if it enters in a joint, it will expand with elasticity. When the locking member 21 enters the joint and expands, the heat insulating material 11 of the fore edge 1a is pushed and deformed by the locking piece portion 21a, and the locking piece portion 21a is deformed by the metal plate on the outdoor side. It will be caught on the edge of 13.

  The main body member 22 faces the surface portion 21b of the locking member 21, and is positioned between the four stopper portions 21d and the surface portion 22a of the outer wall panel 1 beyond the stopper portion 21d. It consists of the overhang | projection site | part 22b located in the outdoor side.

  The main body member 22 also has elasticity, and the position of the edge of the overhanging portion 22b is in a natural state and is located on the indoor side (back side) from the tip of the locking piece portion 21a. For this reason, when the locking member 21 is mounted in the joint, the edge of the metal plate 13 on the outdoor side is sandwiched between the edge of the overhanging portion 22b and the tip of the locking piece 21a. (See FIG. 2). Further, a warped portion 22c bent toward the outer wall panel 1 is formed on the edge side of the overhanging portion 22b so that the edge surface of the overhanging portion 22b is not exposed to the outside.

  Further, as shown in FIG. 3, the warped portion 22c is not formed on one end side (for example, the lower end side) of the main body member 22 in the longitudinal direction, and the width is narrowed. The joint covers 2A adjacent to each other in the vertical direction can be easily connected to each other.

  If it is said structure, since the said joint cover 2A will be latched by the said locking piece part 21a by inserting the said locking member 21 in a joint, it is excellent in the workability | operativity of attachment. Moreover, since the joint cover 2A is not fastened to the trunk edge or the pillar with a screw, a water stop treatment is not necessary. Further, since the joint cover 2A is not fastened to the outer wall panel 1 with screws, the joint cover 2A is hardly damaged by the displacement of the outer wall panel 1. Moreover, since it has the said recessed part 21c, as shown in FIG. 1, it becomes possible to provide the fireproof material 6 in this recessed part 21c, and to aim at fire prevention of the joint of an outer wall. Instead of forming the refractory material 6 as a piece and placing it in each concave portion 21c, the refractory material 6 may be formed long and provided over the plurality of concave portions 21c. Moreover, you may provide a refractory material also between the said edge 1a.

  When the main body member 22 includes the surface portion 22a and the overhanging portion 22b, the locking member 21 and the main body member 22 can be coupled with the surface portions 21b and 22a facing each other. Misalignment between the stop member 21 and the main body member 22 is less likely to occur. In addition, the degree of dent of the surface portion 22a can be reduced with respect to the overhanging portion 22b of the main body member 22 to improve the appearance of the outer wall. Since the locking member 21 has the concave portion 21c, it is easy to reduce the degree of depression of the surface portion 22a of the main body member 22.

  Further, in the joint cover 2 </ b> A, the main body member 22 can be detached from the locking member 21 by operating the screw 24. Thus, even when the joint cover 2A is misplaced, the locking member 21 can be easily removed from the joint, and maintenance is facilitated. It is also possible to adjust the distance between the main body member 22 and the locking member 21 using the screw 24.

  If the stopper member 21 d that prevents the locking member 21 from rotating with respect to the main body member 22 is formed, the locking member 21 can be moved when the locking member 21 and the main body member 22 are connected by a screw 24. It is possible to prevent idling.

  FIG. 5 shows a joint cover 2 according to another embodiment. Differences from the joint cover 2A will be mainly described.

As described above, the joint cover 2 can be easily manufactured when the engagement member 21 and the main body member 22 are joined by the rivet 23 or the like. Further, if the engagement member 21 and the main body member 22 are joined by the rivet 23, the stopper portion 21d is not particularly necessary.

  Next, based on FIG. 6, the outer wall structure serving as a protruding corner using the joint cover 2A will be described. In this outer wall structure, the joint cover 2A is provided at a joint formed between the fore edge 4a of the outer wall panel 4 forming the corner portion provided at the protruding corner portion and the fore edge 1a of the outer wall panel 1 positioned adjacent thereto. In addition, a protruding portion 4b to which the locking piece portion 21a of the locking member 21 is locked is formed on the small edge 4a of the outer wall panel 4 forming the corner portion. The small edge 4a is made of, for example, a metal plate and does not deform even when pressed by the locking piece portion 21a. The tip of the locking piece portion 21a is a corner portion where the protruding portion 4b and the small edge 4a intersect. Will be located. The outer wall panel 4 is fixed to the column 5 with a drill screw 41, and the outer wall panel 1 is fixed to the column 5 with a drill screw 31.

  In this way, joint processing using the joint cover 2A can be performed at the corner of the outer wall. In addition, the said joint of the outer wall structure used as a protrusion corner can also be plugged up using the said joint cover 2 instead of the said joint cover 2A.

  Next, based on FIG. 7 and FIG. 8, the joint cover 2 </ b> B of another embodiment and an outer wall structure serving as a corner using the joint cover 2 </ b> B will be described. Adjacent outer wall panels 1 forming the outer wall structure serving as the corner of entry intersect, for example, at 90 degrees, and the extension line of the end face of the outer edge panel 1a of one outer wall panel 1 is an abbreviation of the outer edge panel 1a of the other outer wall panel 1. It is provided so as to be located on the center side.

  On the front end side of one locking piece portion 21a in the joint cover 2B, a warping portion 21f that wraps and locks from the outdoor surface side of the outer wall panel 1 toward the small edge is formed. In this example, the one locking piece portion 21a protrudes in the indoor direction with respect to the surface portion 21b of the locking member 21, and the warped portion 21f is folded at the tip of the one locking piece portion 21a. . In addition, the locking member 21 has the other locking piece in a state where the warped portion 21f pierces the small edge 1a and the bent bending start portion of the warped portion 21f is caught on the edge of the metal plate 13 on the outdoor side. The tip of the portion 21 a is formed so as to hit the edge of the metal plate 13 on the outdoor side of the other outer wall panel 1. In the main body member 22 of the joint cover 2B, one overhanging portion 22b and the other overhanging portion 22b are formed in an intersecting manner. Thus, joint processing using the joint cover 2B can be performed at the corners of the outer wall.

  In the joint cover 2B, the locking member 21 and the main body member 22 are connected to each other by a screw 24 so as to be separable. However, like the joint cover 2, the surface portions 21b and 22a are joined to each other by a rivet 23. May be. However, as shown in FIG. 7, in the joint cover 2B, the locking member 21 and the main body member 22 can be inserted into the joint with a gap therebetween, so the warped portion 21f It becomes easy to hook on the edge of the metal plate 13 on the outdoor side.
