Description

  The present invention relates to a unit type building.

  Conventionally, a unit building constructed by connecting a plurality of box-shaped room units manufactured in a factory is known.

  The box-type room unit usually has a frame in which pillars at four corners are connected by beams, and a wall panel or the like for partitioning the room is attached to the frame. Building a unit-type building using box-type room units can be done simply by transporting and connecting multiple room units manufactured in the factory to the work site. It is excellent in that it can be reduced and the construction period can be shortened.

  However, when building a building with multiple levels in the above unit building, the room units that form each level are integrated and the interior of the building is partitioned by pillars and panels, so a staircase that connects the levels is installed. In order to do this, it was necessary to install an external staircase or open the floor of a room unit at a specific location and install a staircase there.

  On the other hand, a construction method for a large hall building has been proposed in which a large interior space (a large hall) is constructed by surrounding a building with a box-shaped room unit (see, for example, Patent Document 1). According to the construction method of the hall building, the internal space can be formed in any size by forming a wide internal space by the unit group in which a plurality of room units are connected.
