In this unit building, when building a building using a plurality of building units formed by joining a plurality of upper beams, lower beams and columns to each other in a substantially box shape, the plurality of building units are spaced apart from each other. The connecting beam is stretched between the building units that are spaced apart from each other, and the floor frame is installed on the connecting beam. Therefore, according to the above-mentioned conventional unit building, a building space is formed even between the building units that are spaced apart from each other, and columns, beams, etc. of adjacent building units do not overlap each other, and structural waste is eliminated. You can get a unit building.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional unit building,
It is necessary to use a connecting beam for the construction of the floor frame,
Its processing and attachment work are required. Further, since the floor frame is installed on the joint beam, the floor surface level is raised by the height of the joint beam to increase the height, and accordingly, the ceiling height of the space above the floor decreases.

An object of the present invention is to further simplify the structure of a unit building and form a large building space.

[Means for Solving the Problems] In the present invention, when a building is constructed by using a plurality of building units formed by joining a plurality of upper beams, lower beams and columns and having a substantially box shape, In a unit building in which a plurality of building units are arranged at intervals, a floor frame is arranged between the upper beams of the building units that are spaced apart from each other, and both side portions of the floor frame correspond to the corresponding building units. Is supported on the upper ends of at least two pillars.

[Operation] According to the present invention, a unit space is formed in which a building space is formed between building units that are spaced apart from each other, and columns, beams, and the like of adjacent building units do not overlap each other, and structural waste is eliminated. Obtainable.

Here, each side of the floor frame is directly supported by the upper ends of at least two columns of the corresponding building unit. Therefore, an intervening structure such as a connecting beam for supporting the floor frame on the building unit is not required.

Further, since the floor frame does not have the above-mentioned intervening structure, the floor level is not lifted by the presence of the intervening structure, and the floor level is as low as the upper end of the upper beam of the corresponding building unit. The ceiling height can be set high.

That is, it is possible to further simplify the structure of the unit building and form a large building space.
