Description

The present disclosure relates to an eaves structure and a method for exchanging eaves parapets.

Conventionally, there is known an eaves structure in which a plurality of eaves parapets are arranged side by side along the eaves in a fascia portion of the eaves of a roofing material such as the roof of a building (see, for example, Patent Document 1-4).

In the eaves structure described in Patent Document 4, a beam is arranged along the eaves at a position below the eaves, and a plurality of arms extending from the beam to the front of the eaves are provided at predetermined intervals in the direction along the eaves. A fixing bracket is provided at the tip of each arm. Then, a plurality of eaves parapets arranged side by side along the eaves are fixed to the fixing bracket.

Japanese Unexamined Patent Publication No. 2002-106129 Jitsukaihei 6-44898 Gazette Japanese Unexamined Patent Publication No. 2002-106128 Japanese Unexamined Patent Publication No. 2015-221988

By the way, there are a plurality of eaves parapets having different shapes depending on the specifications of the building, and the shapes of the fixing brackets also have different shapes so as to be able to abut on the inner surface thereof according to the shape of each eaves parapet. ..
Therefore, in the past, when replacing the eaves parapet for remodeling a building or the like, in order to support the new eaves parapet with the existing fixing bracket, it was necessary to replace the eaves parapet with the same shape as the existing eaves parapet.

However, as new specifications of buildings are developed year by year and eaves parapets and fixing brackets of different shapes are manufactured accordingly, the types of eaves parapets required for replacement also increase year by year, leading to cost increases.

The present disclosure has been made in view of such conventional problems, and an object of the present invention is to provide an eaves structure and a method for exchanging eaves parapets, which can be shared with fixed brackets and eaves parapets.
