In FIGS. 1 and 2, a vertical trunk edge 18 is fixed to a surface of a building wall 17 or the like at a desired interval by an anchor bolt or the like. Is fixed by the fixing means 19. At this time, it is preferable to interpose the spacer 20 so as to absorb the unevenness of the wall 17. Further, when the temporary receiving member 21 for locking the exterior panel 5 is fixed by the fixing means 19 also in the lateral direction, the operation is facilitated. The temporary receiving member 21 is formed by assembling a receiving frame 21a and a locking plate 21b with screws 21c, for example.

At this time, it is preferable that the lower surface of the upper end piece 3a of the upper connection portion 3 be locked to the locking plate 21a of the temporary receiving member 21. In addition, the side edges 2 of the exterior panel 5 located vertically are communicated with each other in the vertical direction.

Is fixed to the building with the ridge 13 provided with the draining portion 16. That is, as shown in FIG.
The rear surface portion 2d is opposed to the vertical barrel edge 18, the packing material 15 of the pressing edge 13 is faced within the facing interval, and fastening means 22 such as a screw passed through the pressing edge 13 is attached to the vertical barrel edge 18. By screwing in, the rear surface 2 d of the exterior panel 5 is sandwiched between the vertical rim 18. At this time, as described above, the hanging piece 4d
The standing piece 3b overlaps with the standing piece 3b to increase the thickness, but a draining portion 16 is formed in a shape corresponding to the pressing edge 13, and the overlapped portion is loosely fitted in the draining portion 16. Therefore, the ridge 13 does not rise at the overlapped portion. Moreover, the packing material 15 having elasticity is provided on the pressing edge 13,
Since the draining portion 16 is provided, it is possible to reliably prevent rainwater from entering. Since the draining portion 16 is provided with an outward downward slope, rainwater that has been prevented from entering by the packing material 15 can be guided to the outside of the exterior panel 5 by the external gradient of the draining portion 16.

で、雨水が浸入し難い構造となる。The vertical joint 23 has a narrow entrance, that is, the interval between the side plates 2a of the exterior panel 5 adjacent to the left and right is narrower than the interval between the side surfaces 2c. More precisely, the rib 1 of the ridge 13
3b is smaller than the interval. Therefore, the airflow entering from the entrance of the vertical joint 23 temporarily widens between the ribs 13 b on the front side of the ridge 13. Next, the widened airflow is applied to the ribs 13.
After the width has been reduced in the gap between the front end 2b and the front surface 2b, the width is increased again in the space between the rib 13b and the side surface 2c. Therefore, in the vertical joint 23, the pressure increases toward the inside, and becomes almost equal to or slightly higher than the atmospheric pressure. Therefore, the structure is such that rainwater does not easily enter.

Can be adjusted.

が可能である。On the other hand, also in the horizontal joint section 6, the distance between the entrances of the horizontal joint section 6, that is, the exterior panel 5 located on the lower side is used.
The distance between the upper end piece 3a and the lower end piece 4a of the exterior panel 5 located on the upper side is smaller than the distance between the horizontal piece 4c and the upper end piece 3a that continue via the standing piece 4b. A communication port 11 is provided at an end of the standing piece 4b, and communicates with a large space on the back side of the face plate 1. Therefore, also in the horizontal joint part 6,
The air flow repeats narrowing and widening, and the pressure increases as it goes inward, and becomes almost equal to or slightly higher than the atmospheric pressure. Therefore, the structure is such that rainwater does not easily enter. Further, the width of the horizontal joint portion 6 can be adjusted within the overlapping range of the standing piece 3b of the exterior panel 5 located on the lower side and the hanging piece 4d of the exterior panel 5 located on the upper side.

a and 10b have the effect of preventing the rainwater in the horizontal joints 6 from flowing down into the vertical joints 23 and blocking the air (wind) moving at high speed in the horizontal joints 6. Is located in the area of the "blocked air pocket"
Moreover, since the pressure is surely higher than the atmospheric pressure, the pressure in the internal space of the exterior panel 5 is increased. In addition, since the water avoiding member 12 is mounted on the upper surface of the horizontal piece 4c, the splash of rainwater may temporarily collect on the upper surface of the lower end piece 4a and inside the convex groove 7, but the outer panel 5 It does not reach the interior space directly.

Provided is an exterior structure of a building in which an exterior panel provided with a lower connection portion having a substantially S-shaped cross section at a lower edge thereof is disposed in a vertical direction and a horizontal direction,
Since the air pressure applied to the face plate was introduced to the rear of the face plate through the communication port provided in the lower connection part through the communication port, the air pressure behind the exterior panel was made almost equal to or slightly higher than the atmospheric pressure,
It is difficult for rainwater to enter from each joint. In addition, since the packing material provided on the ridge is not exposed to the outside, it is not directly exposed to ultraviolet rays or the like, the deterioration is moderate, the service life is significantly increased, and the practical value is extremely high. Further, since the drainage portion is provided on the ridge, the sprayed rainwater can be guided to the outside, so that the rain finish is good.
