Description

[Detailed description of the invention] This invention relates to an exterior wall structure, and aims to provide an exterior wall structure that is easy to construct, has a long waterproof life, and is highly reliable.

An embodiment of this invention will be explained based on FIGS. 1 to 3.

That is, as shown in FIGS. 1 and 2, this outer wall structure has an upper part 1 shaped like a flat plate, a lower part 2 bent outward and downward in a Z-shape, and a lower end 3 of the upper part 1 extending inward and upward. The above-mentioned upper part 1 of the water section 4, which is bent in the following manner, is held between the exterior material 6 of the second floor exterior wall panel 5 and its lower frame material 7.

In addition, since the exterior wall panel 5 has the exterior material 6 attached at a position set back from the lower end surface of the lower frame material 7, the lower frame material 7 is formed to protrude downward from the lower end surface of the exterior material 6. As a result, a vertical curtain insertion space 19 is created between the lower part 2 of the water section 4, that is, the part bent outward and downward, and the lower frame member 7.

A waterproof caulking material 8 is provided in this insertion space 19.
At the same time, the upper end 9 of the curtain plate 11 with the upper end 9 bent outward and downward and the lower end 10 bent inward and upward is pressed into the caulking material 8 from below. The lower part 12 is the exterior material 14 of the wall panel 13 on the first floor.
15 plywood and 1 adhesive waterproof rubber asphalt sheet
6 and fixed with nails 17.

Note that the outer wall panels 5 and 13 on the first and second floors are connected via beams 18.

In addition, in this embodiment, the water section 4 and the curtain plate 11
Both are formed by bending galvanized steel plates, and are painted in the same color as the exterior materials 6 and 14.

In addition, the water section 4 is assembled into the outer wall panel 5 when the outer wall panel 5 is assembled in the factory, and is strongly bonded to the lower frame material 7 and the exterior material 6 using epoxy adhesive or the like.
Smooth transmission of structural strength forces.

Because of this structure, when constructing this curtain board 11, after installing the first and second floor exterior wall panels 13 and 5, the difference between the lower frame material 7 and the water section 4 of the second floor exterior wall panel 5 must be adjusted. Fill the caulking space 19 with caulking material 8, insert the upper end 9 of the curtain plate 11 from below, and secure the lower part 12 with nails 17.
It can be easily installed by simply fixing it to the outer wall panel 13 of the floor as shown in FIG.

In addition, caulking material 8 and rubber asphalt sheet 1
According to 6, rainwater is divided into curtain board 11, water section 4 questions, and curtain board 1.
1 and the outer wall panel 13 and can be prevented from entering the wall.

Moreover, since the caulking material 8 is filled inside the water segment 4, it is not directly exposed to sunlight or the outside air, and therefore, it is less likely to deteriorate and has improved durability.

Further, since the rubber asphalt sheet 16 is placed inside the part fixed by the nails 17 of the lower part 12, rainwater etc. will not seep through the nail holes, and caulking can be omitted.

Moreover, since this rubber asphalt sheet 16 is also disposed on the back side of the curtain plate 11 and is not exposed to the outside, the rate of deterioration can be reduced and the waterproof life can be extended.

Furthermore, since the water strips 4 and the curtain plates 11 can be produced in a factory, they are of stable quality and highly reliable, and work losses such as on-site rework are eliminated, making it possible to improve construction efficiency.

Further, since the water strip 4 and the curtain plate 11 are finished in the same color as the exterior materials 6 and 14, the connecting portions are not noticeable and the appearance is excellent.

Furthermore, since the lower end 10 of the curtain plate 11 is bent inwardly and upwardly, this lower end 10 functions as a water cutter, and therefore there is no need to separately attach a water cutter plate below the curtain plate 11.

Moreover, since the lower end 3 of the water section 4 is bent inward and upward, and the upper end 9 of the curtain plate 11 is bent outward and downward,
When fixing the lower part of the curtain board 11 to the lower floor exterior wall panel 13,
Even if you accidentally shift the curtain plate 11 downward, the lower end 3 of the water section 4
can lock the upper end 9 of the curtain plate 11 and prevent it from coming out from the curtain plate insertion space 19.

As described above, this exterior wall structure is easy to construct,
Moreover, the effect of having a long waterproof life and excellent reliability can be obtained.
