  Aluminum fences are strong and durable, but are more expensive than synthetic resin ones, and so far mainly used as rainwater drainage fences for large buildings such as public facilities, commercial facilities, and condominiums. It has been used, but recently, it is also being studied for use in eaves of detached houses, focusing on the design that the texture of aluminum materials brings about.

  The aluminum eaves can be installed using eaves eaves as well as the eave eaves made of synthetic resin, but unlike eave eaves made of synthetic resin, which is lightweight and elastic, Since it is heavier and harder than the resin one, it cannot be stably held at the installation position simply by engaging it with a plurality of eaves hooks. If the aluminum eaves are simply suspended by the eaves suspension, there is a risk that the eaves will hit the eaves during a strong wind and make an impact sound or be removed from the eaves suspension. If the eaves rods are screwed to the eaves rod suspensions in order to securely fix them at the installation positions, the work man-hours required for the installation become great.

  If you fix the aluminum eaves directly to the eaves without using the eaves hanger, the work of attaching the eaves hanger will be unnecessary and the number of parts will be reduced. The fixing position of the eaves must be specified precisely, and the person who supports the eaves horizontally at the fixed position and the person who screws the eaves must work together. Must be many. Since an aluminum eaves is heavy, one worker cannot fix it while supporting it along the eaves.

  Also, if the bent joints that are attached to the corners and corners along with the aluminum eaves and the fences that are installed along the wind at the edge of the roof are made of aluminum, the entire roof fence has a unified texture. The design is improved, however, if a special bent joint or a joint on the keraba side is molded, the processing cost is bulky and the construction cost around the eaves of the roof cannot be reduced.

  SUMMARY OF THE INVENTION In view of the above-described problems of the prior art, the present invention is capable of fixing an eave ridge made of a hard material, such as aluminum, to a predetermined position along the eave with a small number of work steps, and around the roof. It is an object of the present invention to construct an eaves-shell structure having a uniform design while reducing the processing cost of members.

In order to solve the above-mentioned problem, the eaves ridge structure of the present invention comprises an eaves ridge support member having a concave stepped portion at the top, a front surface portion, a bottom surface portion, and a rear surface portion, and is formed in a substantially U-shaped cross-sectional shape.
