In the outer wall structure arranged on the outer wall surface and attached to the outer wall surface, a first locking portion having a folded piece portion facing the outer wall surface at a side end of one panel member of the right and left adjacent panel members. And forming a second locking part having an outer opening-shaped vertical groove having a pair of inner flanges at the side end of the other panel member corresponding to the first locking part, The tip end of the folded piece portion of the first engaging portion 5 is engaged with one of the inner flanges of the second engaging portion from the inside, and the base end portion of the folded piece portion of the first engaging portion is fixed. The other inner flange of the second locking portion is brought into contact with the inner flange from the outside to connect the adjacent panel members in a state where the outer opening of the concave groove is covered, and 2 The attachment piece provided on the locking portion is attached to the outer wall surface via the furring strip, and the first lid member is fitted to the outer half portions of the upper and lower ends of the panel member to cover the outer half portion. At the same time, only the inner half of the upper end is covered with the second cover member whose outer end covers the inner end of the first cover member on the upper end side.

[Action]

According to the above-mentioned structure, since a gap is provided between the upper and lower panel members and the lower part of the panel member is opened, the hollow portion between the panel member and the outer wall surface is communicated with the outside. The hollow portion and the outside are always in an equal pressure state, and even if a wind pressure acts on this panel, the panel does not exert much pressure. Further, since the lower end of the panel member is open, even when rainwater enters the exterior panel material, the rainwater is discharged from below.

By abutting, the plurality of panel members 3 ... Are connected in the lateral direction.

As a result, the outer opening 45 of the groove 7 is covered without using a separate member such as a decorative material.

Then, the attachment piece 6 of the second locking portion 8 is attached to the outer wall surface 2 by a fastener 16 such as a screw via the furring strip 15 fixed to the outer wall surface 2.

Therefore, at least a hollow portion 17 corresponding to the width dimension of the furring strip 15 is formed between each panel member 3 ... And the outer wall surface 2.

Incidentally, as shown in FIG. 4, it is also preferable to form a protruding piece 44 at the tip of the inner flange 9 of the second locking portion 8 in order to prevent disengagement.

Then, the panel members 3 are arranged side by side in the lateral direction, and are attached to the outer wall surface 2 with a gap 18 provided between them.
In this case, the upper end 19 is covered and the lower end 20 is opened.

That is, the first lid members 21, 21 having an L-shaped cross section are fitted to the outer half portions (outer than the inner collar 9) of the upper end 19 and the lower end 20 of the panel member 3 to cover the outer half portions. .

Further, only the inner half of the upper end 19 of the panel member 3 is covered by the second cover member 22 whose outer end covers the inner end of the first cover member 21 on the upper end 19 side.

The second cover member 22 includes a vertical wall 24, an inward horizontal wall 25 connected to the lower end of the vertical wall 24, and an outward horizontal wall 26 continuously provided near the lower end of the vertical wall 24. The inner horizontal wall 25 is made of a mold material and is fixed to the upper surface 34 of the furring strip 15 by a fixing tool 16 such as a screw, and the outer horizontal wall 26 is covered by the first cover member 21. The upper end except the cover is covered. That is, the horizontal wall 26 is set to project slightly outward from the inner flange 9 in plan view, and the hanging piece 35 of the horizontal wall 26 contacts the first lid member 21. Further, a blocking member 36 such as EPT sponge is interposed between the second cover member 22 and the exterior panel 1. The second cover member 22 also covers the concave groove 7.

Therefore, the hollow portion 17 between the panel members 3 ... And the outer wall surface 2 is communicated with the outside, and the hollow portion 17 and the outside are always in an equal pressure state.

Further, the concave groove 23 formed by the engaging portions 5 and 8 is open without being covered at the upper and lower sides.

The furring strip 15 is a long body having a downwardly opening concave groove portion 27 in cross-sectional shape and a hanging piece 28 to which the mounting piece 6 is attached, and is a rigid body that is installed in an outer wall 29. The first bracket 31 made of an angle member fixed to the edge 30 and the second bracket 32 made of an angle member fixed to the first bracket 31 are attached to the rigid furring strip. Reference numeral 33 denotes a fixing tool composed of bolts and nuts for fixing the furring strip 15 and the second bracket 32, and the head portion of the nut is inserted into the concave groove portion 27 of the furring strip 15.
