FIG. 4A is a longitudinal sectional view of the metal siding used in this structure, and FIGS. 4B and 4C are enlarged views of the upper and lower portions of the metal siding.

  Between the beam 1 and the base 2 (or between the beams), columns 3a and 3b and an inter-column 3c (hereinafter, the inter-column may also be simply referred to as a column) are erected. A metal siding 10 as a face material is fastened to the beam 1, the base 2, and the pillars 3a, 3b, or 3c by screws 4.

  The bonding adhesive 5 is filled in the horizontal joint portion of the metal siding 10. The horizontal joint has a combined shape and is continuously provided in the entire joint area in the horizontal direction.

  Reference numeral 6 denotes a hole-down hardware, and 7 denotes a battledore bolt.

  In this embodiment, the metal siding 10A on the upper half of the metal siding 10 cut in the horizontal direction is arranged at the lowermost stage, and the metal siding 10B on the lower half of the cut is placed on the uppermost stage. Has been placed.

  This metal siding 10 is a real double-sided steel sheet sandwich panel, and includes a first metal plate (steel plate) 11 constituting a front surface, a second metal plate (steel plate) 12 constituting a rear surface, and a first metal plate 11. It has the heat insulating material 13 which consists of foaming synthetic resins, such as a foaming polyurethane foam, provided integrally with the 2nd metal plate 12. As shown in FIG.

  As shown in FIG. 3, a convex portion 10a is formed at the upper end of the metal siding 10 so as to reduce the thickness, and a concave portion 10b into which the convex portion 10a can be inserted is formed at the lower end surface. The upper end sides of the metal plates 11 and 12 also cover the front and rear surfaces of the convex portion 10a, respectively. Moreover, the lower end side of each metal plate 11, 12 wraps around into the recess 10 b from the front side and the rear side of the metal siding 10. A rubber packing 10c is provided on the back end surface of the recess 10b.

  The protruding height of the convex portion 10a is larger than the concave depth of the concave portion 10b (depth to the rubber packing 10c). Therefore, the metal sidings 10 and 10 are made to engage with each other so that the convex portion 10a and the concave portion 10b are engaged. When mounting is performed, a gap is generated between the shoulder portion of the convex portion 10 a of the lower metal siding and the lower end surface of the upper metal siding 10. This gap is exposed on the front side of the wall surface as a concave groove extending in the horizontal direction.

When constructing an outer wall using this metal siding 10, first, a moisture permeable waterproof sheet 9 is stretched across a plurality of pillars 3 a, 3 b, 3 c, and a plurality of metal sidings are placed on the front surface of the moisture permeable waterproof sheet 9. 10 are arranged in multiple rows in the vertical direction and in multiple rows in the horizontal direction, and each metal siding 10 is fixed to the pillars 3 a, 3 b, 3 c, the beam 1 and the base 2 with screws 4. When the metal sidings 10 are sequentially stacked from the lower stage to the upper stage, the upper metal siding 10 or the concave part 10b of the 10B is inserted into the convex part 10a of the lower metal siding 10 (or 10A).

The adhesive 5 is filled densely continuously from one end side to the other end side of the metal sidings 10, 10A, 10B in the concave grooves between the metal sidings. The cured product of the adhesive 5, the tensile modulus is of 5 kg / cm ² or more for example 5~20000kg / cm ² as high hardness.

  Although not shown between horizontal metal sidings adjacent to each other in the horizontal direction, a backup material made of expanded polystyrene or the like and an epoxy-based bonding adhesive are interposed between both the end surfaces. Then, tape is applied across both metal sidings.

Thereafter, a finishing material is applied to the metal siding 10, 10A, 10B or finished by tiling.
When tiled, the number of vertical cuts is reduced when it is stretched horizontally compared to when the same size metal siding (face material) is stretched vertically. Although the tile exhibits strength for horizontal cuts, it is easy to break for vertical cuts, so that the strength as a tile construction structure is increased.

  In the outer wall of this building, the metal siding 10, 10A or 10B adjacent in the vertical direction is joined by the adhesive 5 having high rigidity, so that the wall has high rigidity.

  Therefore, the outer wall has a sufficiently high wall magnification of 3 times or more without necessarily providing a brace. Moreover, in this outer wall, since each metal siding 10, 10A, 10B is equipped with the metal plates 11, 12, the curvature by a time-dependent change is also prevented and the beautiful external appearance is maintained over a long period of time.

  Although the actual sandwich panel is used in the embodiment of FIGS. 1 to 4, other metal siding may be used.

  For example, an interlaced double-sided steel sheet sandwich panel 20 shown in FIG. 5 (a) may be used.
