However, since the arabesque described in Patent Document 1 follows the shape of the housing, the appearance design has to be “stepped” and has poor design.
On the other hand, the arabesque described in Patent Document 2 has a problem in that an increase in the number of parts is unavoidable and construction takes time. In addition, there is a problem that the support material and the like must be carried out separately from the roof construction in order to take it out from the wall.
And what can be said in common with such Patent Documents 1 and 2 is still inadequate in terms of improvement in design and versatility at the eaves.

  Therefore, the present invention has an object to provide an eaves structure of a building that can improve the design and versatility at the eaves, and can perform construction work quickly and easily, and can also finish makeup such as eaves ceilings. To do.

  The present invention has been proposed in view of the above, and on the back side of the roof base that supports the exterior structure, an eave ceiling support member that supports the decorative material is attached to at least one of the front side or the back side. Further, the present invention relates to an eaves-end structure of a building, characterized in that the front end of the eave ceiling support member is attached in an extending shape from the eave end of the roof base.

  Further, according to the present invention, in the eaves-end structure, the eave ceiling support member is disposed in an upwardly inclined shape, and a recess is formed at the tip of the roof base and the eave ceiling support member, and a water-impermeable material is disposed in the recess. We also propose an eaves structure for buildings, which is characterized by the formation of drainage.

The eaves-end structure of the building of the present invention has an eaves top support member that supports a decorative material on at least one of the front side and the back side of the roof base that supports various exterior structures, Since the top of the eaves top support member is attached in an extended form from the eaves end of the roof base, it is easier to construct a roof that has a sharper tip than a normal general roof. It is also possible to form a space that can be effectively used as rain eaves and sun shades in a predetermined area.

In the latter mode, as shown in the illustrated embodiment to be described later, the upper support member, which is a square pipe member, is assembled and tightened and connected to the support member of the exterior structure, which is a hat-like rod-shaped member. Also good.

  The communication support member connects (connects) the eaves support member and the upper support member, and is arranged in an inclined shape even if arranged in a substantially vertical shape. May be. This communication support member may be a single member, or may be a communication support member by combining a plurality of members that allow length adjustment, for example. Further, the communication support member is not limited to connecting the end portions of the upper support member and the eaves support member, and connects one or both middle portions of the length. Also good. For this reason, a plurality of communication support members may be provided. In that case, the number of connection points increases and the integrated strength is improved.

In addition, it is preferable that at least one of any of the support members is attached to the housing, but it is not necessarily attached directly to the driver, and may be attached via an auxiliary member.
As this auxiliary member, one end is connected to the support member directly or via another member, and the other end is attached to the housing (wall portion). The auxiliary member may be linear or curved. Further, the auxiliary members may be provided on all the support members or provided at regular intervals (for example, every other line). In addition, when providing such an auxiliary member, various decorative materials may be attached directly to the eaves top support member or the upper support member, or may be attached via the auxiliary member.
