[Prior Art] Conventionally, it has been desired to effectively utilize the space under the eaves that is formed under the roof that protrudes from the building body toward the eaves. Overhanging structures are formed in buildings, and these overhanging structures are used to widen the indoor space of buildings. When forming an overhanging structure, auxiliary pillars are erected at the eaves of the roof, or auxiliary beams are installed horizontally protruding toward the outdoors from the roof beams that support the eaves of the roof. External wall panels are vertically installed downward from the tips of beams to form overhanging structures.

0003

[Problem to be Solved by the Invention] However, in the conventional example as described above, when the auxiliary beam is installed horizontally protruding from the roof beam, the eave part of the roof is also changed according to the construction state of the auxiliary beam. There was a problem that the shape of the roof was different from other parts, resulting in a poor appearance.Additionally, if auxiliary pillars were installed, the number of construction steps would increase.

The purpose of the present invention is to solve the above-mentioned problems, and it is possible to partially protrude the main body of the building to form an overhanging structure without changing the shape of the auxiliary pillars or the roof. The aim is to provide a structure for the eaves of a building that can increase the space available.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an auxiliary beam 2 that projects diagonally downward from a roof beam 1 that supports the eaves of the roof of a building toward the eaves. An under-eave front beam 3 is provided at the tip of the beam 2, and an external wall panel 4 is vertically disposed downward from the under-eave front beam 3 to form an overhanging structure 6 that partially protrudes from the building body 5 to the outside. A space a within the overhanging structure 6 and an indoor space b within the building body 5 are communicated with each other.

[0006]

[Operation] Therefore, the overhanging structure 6 can be formed using the auxiliary beam 2 that projects obliquely downward from the roof beam 1, and it is possible to change the shape of the eaves of the roof. The overhang structure 6 can be formed in a part of the building body 5, and the indoor space b can be expanded by forming the overhang structure 6 without making any major construction changes.
