The filling work of the caulking materials 109 and 110 is a work at a high place, and particularly when the caulking material 110 is filled between the rear end portion of the upper cover 108 and the surface u of the outer wall material, the filling work is performed from above. The work efficiency is poor. Further, since the filled caulking material 110 is directly exposed to rainwater and deteriorates quickly, the rainwater infiltrates into the upper cover 108 due to the deterioration and flows down below the holder 100. In addition, it is necessary to repair frequently every time there is deterioration, and the repair work is also a work from above, and the workability is remarkably poor. Further, since the holder 100 is attached to the surface u of the outer wall material, the holder 100 and the upper cover 108 greatly protrude from the surface u of the outer wall material, and the appearance of the entire eaves is deteriorated.

INDUSTRIAL APPLICABILITY According to the present invention, the outer wall material can be efficiently filled and repaired, and the outer wall material can be provided with a good-looking eaves in which the holder and the upper cover do not protrude greatly from the surface of the outer wall material. The purpose is to allow the eaves plate to be repaired or replaced without peeling.

The eaves according to the present invention have an eaves plate, a holder for holding the rear end portion of the eaves plate, and an upper cover covered on the holder. The front end of the upper cover is supported on the rear end of the eaves plate, and the rear end is connected to the front end of the second cover via a separable connection.

To install the eaves in a building, the holder is attached to the ground below the outer wall of the building, the holder is made to hold the rear end of the eaves plate, and the holder is covered with an upper cover. The front end of the top cover is supported on the rear end of the eaves plate, and the rear end is screwed and fixed to the base of the outer wall of the building. An outer wall material that covers the base of the outer wall of the building is layered on the rear end of the upper cover. The front surface of the gap between the upper surface of the upper cover and the lower end surface of the outer wall material is open, and the gap is filled with caulking material from the open portion. The work of filling the gap with the caulking material and the work of repairing the deteriorated caulking material can be performed efficiently because the work is performed from the front. The holder and top cover are half-buried in the outer wall material and do not protrude more than the surface of the outer wall material, resulting in a good-looking eaves. Further, by separating the first cover portion from the second cover portion at the connecting portion, the eaves plate can be easily repaired or replaced.

The connection portion may have various forms, but in order to facilitate the separation work, the rear end portion of the first cover portion is engaged in the concave groove provided in the front end portion of the second cover portion. It is desirable to have a configuration that is suitable for this.

The top cover preferably has a strip-shaped trailing edge at the trailing edge, the trailing edge of which is stacked and screwed onto the ground below the outer wall of the building. According to this embodiment, even if the caulking material deteriorates, rainwater does not enter the inside of the upper cover from the rear end portion of the upper cover.
