Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit with a balcony and a unit construction method for installing the building unit.

[0002]

2. Description of the Related Art Many multi-story houses such as two-story houses have a balcony on the upper floor. A balcony generally has no roof or ceiling, but it is a floor part that protrudes from the outer wall of the upper floor of the building as an extension of indoor life.Normally, handrails are provided along the three side edges of the floor part to prevent falling. Has been. Further, as one method for increasing the industrial production rate of a building, for example, a unit building method is known as described in JP-A-55-152236. A unit building is a building in which one building is divided into several units in advance and produced in a factory, and these are constructed / assembled at a construction site. As a unit that constitutes a unit building, there are a building unit that constitutes each room portion such as a living room, a dining room, and a bedroom, a roof unit that constitutes a roof portion of the building, and a balcony unit that constitutes a balcony. These units are produced in advance in a factory, transported to a construction site, and constructed and assembled. The assembly is carried out by first installing the building units on a foundation and then installing a correspondingly sized roof unit on top of each installed building unit. In particular, for the construction of a two-story unit building, multiple building units are combined vertically and horizontally, a balcony unit is also installed if necessary, and a roof unit is installed on top of the building unit on the upper floor. Is done.

[0003]

By the way, in the prior art,
Regardless of the size of the unit, one functional element is configured as one unit. For example, the building unit is unitized so as to form only the room part, the roof unit only the roof part, and the balcony unit only forms the balcony, and only the predetermined functions are satisfied. Therefore, the total number of units has increased, and the number of man-hours for on-site construction such as raising and lowering the units has increased. In addition, when installing a cantilever balcony unit that can be supported by a cantilever, there is no lower-floor building unit to support, so there was a problem in construction safety.

The present invention has been made against such a background, and provides a building unit with a balcony and a unit construction method which can reduce the number of man-hours for on-site construction, and can also secure work safety and structural stability. It is intended to be provided.

[0005]

In order to solve the above problems, a building unit with a balcony according to claim 1 has a room portion on a part of an upper surface of a floor panel in which joists are assembled to form a floor framework. And a cantilever balcony provided with a handrail and a waterproof floor is provided on at least a part of the remaining part.

Further, in the building unit with a balcony according to a second aspect of the present invention, on the lower surface of the floor panel, a linear portion corresponding to directly above the wall panel of the lower-floor building unit to be arranged immediately below is provided in the upper and lower buildings. A head joint for connecting the units is provided, and at least one of the head joints is provided in a linear portion corresponding to immediately below the boundary line between the room portion and the cantilever balcony or in the vicinity thereof. .

Still further, in the unit construction method according to claim 3, the building unit with a balcony according to claim 1 and the narrow building unit having a width narrower than the width of the building unit with a balcony are provided under the same structure. It is characterized in that the floor panel of the building unit with a balcony and the floor panel of the narrow building unit is bolted together while being fixedly mounted on the upper part of the story building unit.

[0008]

According to the structure of the present invention, since the cantilever balcony is integrally formed on the upper surface of one floor panel constituting the building unit, the cantilever balcony can be assembled only by assembling the building unit on site. Is completed. The upper surface of the floor panel of the cantilevered balcony is exposed to wind and rain, so it must be waterproof. However, if the waterproof layer is formed in the factory in advance, it is not necessary to carry out the waterproofing work on site. If there is no choice but to reduce the width of the building unit with balcony due to road transportation obstacles, a narrow building unit corresponding to the shaved room will be manufactured separately and the lower floor will be constructed locally. The building unit with a balcony and the narrow building unit are installed adjacent to each other on the same building unit to be installed. The structural stability can be ensured by connecting the building unit with a balcony and the narrow building unit to each other by the bolt connection between floor panels in addition to the normal wall panel connection.
