BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, based on the drawings, the same reference numerals are used for members that are substantially the same as or correspond to those of the conventional example
BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of a vertical roof structure and a construction method according to the present invention will be described. FIG. 1 is a cross-sectional view showing the structure of a main part of the vertical roof structure of the present invention. In addition, also in this embodiment, it is assumed that the roofing material 2 is directly fixed to the field board 1 without using a member such as a hanging member or a rain gutter.

In the structure of the present invention, the roofing material 2 is formed with fitting portions 2a for the cover 10 on both sides thereof.
The roofing material 2 is fixed adjacently on the base plate 1, and the cover 10 is arranged between the roofing materials 2. The cover 10 is formed to have a concave cross section, and has a fitting portion 10a for fitting the roofing material 2 at the upper edge thereof.
The waterproof material, that is, the packing 4, is attached to the bottom of the cover 10 between the cover 2 and the roofing material 2.

The fitted portion 2a of the roofing material 2 is provided near the upper surface of the roofing material 2 as shown in FIG. Further, a packing insertion portion 2b is provided as a stepped portion below the fitted portion 2a, and the roofing material 2 is fixed on the field board 1 by a water blocking fixture 5 at the bottom surface thereof. The packing 4 is set between the back side of the cover 10 and the packing mounting portion 2b of the thatch material.

In the structure of the present invention, as shown in FIG. 2, the fitting portion 10a of the cover 10 is set to be wider than the fitted portion 2a of the roofing member 2 by the width δ in its free state. That is, the width δ functions as an error absorbing margin when the cover 10 is assembled and an absorbing margin of the blowing deformation of the roofing material 2. In addition, the cover 10 formed in such a wide width is elastically engaged with the fitted portion 2a by being incorporated into the fitted portion 2a of the roofing member 2.

When constructing the vertical roof of the present invention, the roofing material 2 is used.
Are arranged side by side on the base plate 1, and the bottom surface thereof is fixed on the base plate 1 by the water stop fixing tool 5. Then, as shown in FIG. 2, the cover 10 is pushed from above between the adjacent roofing members 2,
While pressing the packing 4 onto the bottom of the cover 10, the cover 10 is fitted with the packing insertion portion 2b formed as a step on the roofing material 2. In that case, when the cover 10 is pushed in, the cover 10 is once contracted and the fitting portion 10a is engaged with the fitted portion 2a of the roofing member 2.

As described above, in the structure of the present invention, the fitted portion 2a of the roofing material 2 is set above the roofing material 2, so that the cover 1
The fitting state with the fitting portion 10a of 0 can be visually and easily confirmed. Therefore, incomplete fitting can be prevented, so that water leakage can be effectively prevented.

Further, the inner surface of the cover 10, that is, the concave upper surface constitutes a trough portion 10b for rainwater of a normal degree, and the rainwater flows on the cover 10, so that the cover 1
The packing 4 set on the back side of 0 has little chance of contacting rainwater. Therefore, deterioration of the packing 4 due to rainwater is unlikely to occur. Further, since the packing 4 is not exposed to external light, it is not deteriorated by ultraviolet rays. And such packing 4
After being inserted and attached, the concave shape of the cover 10 and the packing 4 respectively realize a complete waterproof structure by primary and secondary waterproofing, so that water ingress into the cover 10 can be minimized. However, if there is a slight amount of water inside the cover 10, the water is drained through the preliminary gutter 2c.
By using a water stop fixing tool for the trough portion 2c, it is possible to prevent water from entering the base plate.

Further, since the fitting portion 10a functions as an error absorbing margin when the cover 10 is assembled, the assembly error can be absorbed and the assembling work can be performed easily and accurately.

[0019]

As described above, according to the present invention, in this type of vertical roof structure, the structure is simple, yet has extremely high waterproof performance, and the manufacturing cost and construction cost are effectively reduced. It has the advantage that it can be done.
