Description

  The present invention relates to a roof structure of a unit type building.

  2. Description of the Related Art Conventionally, a unit type building constructed by combining a plurality of box-shaped building units manufactured at a factory at a construction site is known as one of housing structures. The building unit is composed of four columns erected at the four corners, and ceiling beams and floor beams that connect the upper ends and lower ends of these columns, respectively.

  When a balcony is provided on the top floor of a unit type building configured in this way and an eave is to be provided above the balcony, a method of extending the roof panel so that the end of the roof covers the top of the balcony (For example, refer to Patent Document 1).

JP 2011-236700 A

However, if the eaves are formed above the balcony by extending the roof panel, the eaves of the balcony and other roof panels will invade the adjacent land when the distance from the adjacent land is narrow, such as in urban residential areas. This is not preferable.
In response to this, for example, only the roof panel above the balcony is extended to form an eave, and the roof panel in the other part does not invade the adjacent land, ensuring a hut space without changing the slope. On the other hand, when forming with eaves-down suppressed, a roof structure is conceivable in which a gap is formed between the end of the roof panel and the building, and a curtain plate having a large finding width is provided to cover the gap.

By configuring the roof structure in this way, it is possible to prevent the eaves from entering the adjacent land while providing eaves above the balcony, but the eaves consisting only of the end of the roof panel on the balcony side, and others The design will differ depending on the eaves made of the curtain, and the aesthetics will be impaired.
And since the eaves on the balcony side are not supported by the bundle, there is also a problem of lack of stability.

  Furthermore, such a problem becomes conspicuous in the eaves portion in two directions that form a right angle, such as a protruding corner portion or a corner portion of the roof.

  Therefore, the present invention provides a roof structure that can stabilize the eaves and the eaves of the entrance corner and the entrance corner of the unit type building while maintaining the beauty of the entire roof without allowing the eaves to enter the adjacent land.
