[0002]

2. Description of the Related Art Conventionally, as shown in FIGS.
There is an outer wall construction structure 8 in which a plurality of outer wall plates having a four-sided consensus structure are constructed in a horse riding joint shape. That is, the outer wall plate 2 is
It has an upper lower nut 210, a lower upper nut 220, and lateral lower nuts 240 and lateral upper nuts 230 provided on the left and right (see FIG. 11). Then, the lower solid 220 of the upper outer wall plate 2 is superimposed on the upper solid 210 of the lower outer wall plate 2, and the horizontal solid 230 of the right outer wall plate 2 is placed on the horizontal lower solid 240 of the left outer wall plate 2. Build in layers. Then, in the outer wall construction structure 8, as shown in FIG. 20, the vertical joints 27 formed between the left and right outer wall plates 2 are not continuous in a straight line, and the left and right positions are staggered. It is a horse riding joint.

In the outer wall construction structure 8 shown in FIG.
As shown in FIG. 22, fastening fittings 9 are arranged at the upper end and the lower end of the vertical joint 27 to fix each outer wall plate 2 to a base material 3 such as a furring strip. As shown in FIG. 23, the fastening fitting 9 includes a base plate portion 91 that abuts the back side surface 26 of the outer wall plate 2, a support portion 92 that is erected horizontally in front of the base plate portion 91, and the support member. Upper plate locking portion 93 bent obliquely upward from the front end portion of the portion 92, lower plate locking portion 94 bent obliquely downward from the front end portion of the support portion 92, the upper plate locking portion 93 and the lower plate The front flat plate portion 97 is provided continuously between the front end portions of the locking portion 94.

And, the above-mentioned fastening metal 9 is shown in FIG.
As shown in FIG. 22, the upper and lower outer wall plates 2 are fixed to the base material 3. That is, the fastening metal 9 is the lower plate locking portion 9
4 is locked to the upper side portion 21 of the lower outer wall plate 2, the upper outer wall plate 2 is supported by the support portion 92, and the upper plate locking portion 93 is locked to the lower side portion 22 of the upper outer wall plate 2. In this state, it is fixed to the base material 3 with screws 4.

Further, as shown in FIG. 21 and FIG. 22, caulking material 29 is cast on the upper base 210 and the lower base 240 of the outer wall plate 2. From the top of the caulking material 29, the lower solid 220 and the lateral solid 2 of the other outer wall plate 2
30 overlap and press the caulking material 29. This prevents the inflow of water from the vertical joints 27 or the horizontal joints 270 into the outer wall construction structure 8.

[0006]

However, although the caulking material 29 is placed in the outer wall construction structure 8, it is difficult to reliably prevent water from entering due to the following problems. There is. This problem will be described with reference to FIGS.

Incidentally, FIG. 24 shows a state in which the periphery of the lower end portion of the vertical joint 27 is viewed from the front (front side). In FIG. 24, the contour of the rear portion of each outer wall plate 2 is a portion that cannot actually be seen from the front and is shown by a broken line. The rear part of the outer wall plate, which is outlined by the broken lines with a _{1 to} c ₁ , is integrated with the front part of the outer wall plate, which is shown with the solid lines with a _{2 to} c ₂ , respectively. ing. Further, reference numeral 2a~2c respectively represent an outer wall plate having a contour a ₂ to c ₂ outline a ₁ to c ₁ and the front portion of the rear portion.

As shown in FIGS. 22 and 24, in the outer wall construction structure 8, the rainwater 6 may enter the vertical joints 27. The rainwater 6 that has infiltrated the vertical joint 27 is prevented from moving in the left-right direction (rightward in FIGS. 22 and 24) by the caulking material 29 that is cast on the horizontal bottom 24, and the outer wall construction structure 8 Intrusion into the interior is prevented. However, the rainwater 6 falls down along the vertical joints 27. Then, the rainwater 6 reaches the front flat plate portion 97 of the fastening fitting 9 arranged at the lower end portion of the vertical joint 27.

When the flow rate of the rainwater 6 reaching the front flat plate portion 97 is small, most of it is the vertical joint 27.
Is discharged to the front from the upper side portion 21 of the outer wall plate 2 existing below. However, when the flow rate of the rainwater 6 is large, the pressure of the rainwater 6 that has fallen along the vertical joint 27 is increased at the upper side portion 21 of the lower outer wall plate 2 and a force for flowing in the left-right direction is generated. work. Therefore, a part of the rainwater 6 is, as shown in FIGS. 22 and 24, the front flat plate portion 97.
May flow to the left and right along the front surface of the outer wall plate 2, fall from the side end portion 99 to the upper side portion 21 of the lower outer wall plate 2, and may further penetrate into the back side of the outer wall plate 2.

A part of the rainwater 6 that has moved left and right along the front flat plate portion 97 rides over the upper plate locking portion 93 and reaches the upper portion of the support portion 92 and further to both side end portions 99 thereof. Moving. And this rainwater 6 is also the above-mentioned fastening metal 9
It penetrates into the back side of the outer wall plate 2 from the side end 99 of the. This may lead to corrosion and deterioration of the outer wall plate 2 and the base material 3.

The present invention has been made in view of the above conventional problems, and it is possible to reliably prevent water from being flooded in an outer wall construction structure in which a plurality of outer wall plates having a four-sided joint structure are constructed in a horse riding joint shape.
