Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a unit building with a balcony.

[0002]

2. Description of the Related Art As one method for increasing the industrial production rate of buildings, a unit building method is known. The unit building is a building of a system in which one building is divided into several units in advance to be factory-produced, and these are constructed and assembled at a construction site. The units that make up the unit building include a building unit that makes up each room part, such as a living room, a dining room, and a bedroom, and a roof unit that makes up the roof part of the building. These units are produced in a factory in advance, transported to a construction site, and constructed and assembled. Assembly is
First, a building unit is installed on a foundation, and then a roof unit of a corresponding size is installed on top of each installed building unit.

[0003] By the way, conventionally, one of the lower building units constituting the lower floor portion of the building is assembled so as to protrude from the upper floor building unit constituting the upper floor portion of the building. There is also known a unit building with a balcony in which a roof unit is mounted on a building unit on the lower floor and a balcony unit is mounted on the roof unit (for example, Japanese Patent Laid-Open No. 61-1029).
No. 31, publication). As described above, in a conventional unit building with a balcony, one balcony unit is mounted on one building unit. Therefore, when installing a balcony unit twice as large as the protruding lower-floor building unit, as shown in FIG. 8, two lower-floor building units 200 are arranged side by side to protrude from the upper-floor building unit 100. Assembled in a state where
One balcony unit 300 is placed on each of the two lower building units 200 projecting side by side,
Two balcony units 300 were connected.

[0004]

However, in a conventional unit building with a balcony, as described above, the work is increased because two separate balcony units 300 are attached, and the number of on-site work steps and work time are increased. There is a problem of increasing. Also, if there is no roof on the lower side, rainwater may leak from the connected place,
This part had to be connected watertight, which was inconvenient.

[0005] The present invention has been made in view of the above circumstances, and has as its object to provide a unit building with a balcony that does not require the connection of a balcony unit.

[0006]

According to a first aspect of the present invention, there is provided an image forming apparatus, comprising: a plurality of lower building units constituting a lower floor portion of a building; And that one balcony unit is placed in a state of straddling over a plurality of the protruding lower-floor building units. Features.

According to a second aspect of the present invention, there is provided the unit building with a balcony according to the first aspect, wherein a connecting beam having a lower flange at a lower edge portion on the indoor side of the balcony unit is provided with the lower flange. At least one building unit on the upper floor is mounted on the upper surface of the lower flange so as to protrude toward the indoor side.

[0008]

According to the structure of the first aspect, a plurality of lower-floor building units are arranged and assembled so as to protrude from the upper-floor building units. Since one balcony unit is placed in a state of straddling, there is no seam in this balcony unit. Therefore, there is no need to connect a balcony unit as in the related art, and the number of on-site work steps and work time are reduced. Further, since there is only one balcony unit, it is possible to prevent rainwater from leaking from the floor without providing a roof unit below the balcony unit.

According to a second aspect of the present invention, a connecting beam having a lower flange at a lower edge portion is provided on the indoor side of the balcony unit used in the first aspect of the present invention so that the lower flange projects toward the indoor side. Since at least one upper-floor building unit is mounted on the upper surface of the lower flange, the upper-floor building unit and the balcony unit are firmly connected by connecting beams and do not separate. Also,
Since it can be firmly connected and fixed in this way, waterproofing during this time can be completed.

[0010] Further, by mounting the building unit on the upper floor on the upper surface of the lower flange of the connecting beam, the building unit on the upper floor can be kept in a stable state even before the connection work, so that workability and safety are improved. I do.
