The attic below the sloped roof is sometimes used as an attic. In addition to the ventilation and lighting of the attic, in order to improve the livability of the attic, give accents to the sloped roof, and enhance the appearance of the house, sloped roofs are sometimes equipped with balconies leading to the attic. It is formed.

Conventionally, such a balcony has been formed by a notch provided in a sloped roof, but since the balcony is provided in a sloped roof, its floor body,
The construction of side walls, etc., becomes complicated, which causes a decrease in workability.

[0004] On the other hand, it is desired that the above-mentioned balcony for increasing the livability and comfort of the attic be formed with the simplest possible structure and excellent fireproof and waterproof properties. The inventor utilized a roof beam that forms the frame of the main body of the house and can support the floor of the attic, and also formed the floor with the same structure as, for example, a roof balcony provided on the roof of the house. The present invention was devised by focusing on the possibility of simplifying the structure of a balcony.

[0005] The present invention is based on the idea that a balcony floor is formed by attaching a large roof to the opposing sides of two roof beams parallel to the main roof and spanning a floor panel over the large roof. The purpose of the present invention is to provide a structure of a roof balcony that can form a balcony leading to a sloped roof with a simple configuration, improve workability, and improve the livability of the attic.

[0006]

[Means for Solving the Problems] The present invention provides a structure of a roof balcony in which a balcony leading to an attic is formed by a discontinuous part provided in a sloped roof. In addition to providing the discontinuous part of the sloping roof, a floor panel made of lightweight concrete is installed on the opposing sides of the roof beam, and is spanned over the large extension, and a waterproofing material is placed on the upper surface of the floor panel. An inner wall body that forms the floor of the balcony, has an opening leading to the attic on the roof beam on the upper side of the sloped roof, and connects the upper end of the discontinuous part of the sloped roof. An outer wall body connecting the lower end of the discontinuous part of the sloping roof is provided on the roof beam, while side walls connecting the lateral ends of the discontinuous part of the sloping roof are provided at both ends of the inner wall body and the outer wall body.

[0007]

[Function] A floor panel is attached to the facing sides of the roof beam, and a floor panel and a waterproof material are placed over the panel to form the floor of the balcony. Since the balcony is formed using roof beams capable of supporting the floor of the attic, the structure of the balcony can be simplified and construction efficiency can be improved. In addition, as the waterproof material, for example, a synthetic resin waterproof sheet such as vinyl chloride, or a synthetic rubber waterproof sheet is preferably used, which can improve the waterproofness of the balcony floor and also provide high heat insulation and nonflammability as a floor panel. Since lightweight concrete is used, it also helps improve fire resistance.

Furthermore, an inner wall body having an opening leading to the attic is provided on the roof beam on the upper side of the sloped roof, and an outer wall body is provided on the roof beam on the lower side of the sloped roof, while the inner wall body,
By providing side walls at both ends of the outer wall, the four walls of the balcony are formed.
