DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an eaves part which can form an eave-shaped roof projecting from an outer wall of a house with good workability and can reduce costs.

[0002]

2. Description of the Related Art In recent years, ancillary structures that protrude from the outer wall of a house are often used in order to increase a living area. As shown in FIGS. 5 and 6, such ancillary structures include upper cantilever beams a whose inner ends are bolted to lattice beams h arranged along the outer wall of the house and which are inclined outward and extend. The roof panel pr is attached to the eaves roof r, and the upper end of the outer wall panel pw which forms the outer wall of the attached structure is conventionally provided outward from the lattice beam h below the upper cantilever a. Front beam c at the outer end of the lower cantilever b projecting out
Was supported through.

[0003] On the other hand, in the eaves of a house roof, an eaves ceiling is usually formed by attaching an eaves base material such as a field edge for fixing an eaves ceiling material to a hanging tree hanging from a rafter.

[0004]

However, in the conventional structure using the upper and lower cantilever beams a and b in forming the accessory structure, it is troublesome to attach the upper and lower cantilever beams a and b. The outer wall panel supported by the outer end of the lower cantilever b because the lower cantilever b inclines outward and extends downward, as well as being inferior in workability and increasing the variety of members. It is necessary to prepare an external wall panel pw dedicated to an attached structure, for example, by reducing the height of the pw, which has caused an increase in cost.

In addition, a method of supporting the eaves ceiling via suspension trees,
When applied to the ancillary structure, the outer panel p
Since the eave ceiling d is formed at a position lower than the standard at the upper end of the w, it takes time and effort to adjust the length of the suspension tree, which is one of the causes of lowering workability.

According to the present invention, an eaves roof can be formed with good workability on the basis of bolting a cantilever beam having a substrate provided with a metal fitting for attaching a bark to an outer end portion to a beam material, and the cost can be reduced. It aims to provide an eaves structure that can be reduced.
