  However, in the structure of the conventional unit type building shown in patent document 1, since the structure of the building unit in which the window is installed becomes special, it is necessary to prepare special manufacturing equipment, and the manufacturing cost increases. There is a problem of end. Moreover, in the conventional structure, the window extended upward from the upper end of the building unit could not be provided.

  The objective of this invention is providing the unit type building which can provide the window which protruded upwards from the building unit, without using a special building unit.

In order to achieve this object, the unit type building of the present invention has the following configuration.
That is, with reference to the drawings, the unit building of the present invention includes a plurality of building units 10 and 20 each having a frame formed in a substantially rectangular parallelepiped shape from the pillars 21 at the four corners, the upper beam 22 and the lower beam 23. Among the plurality of building units, at least one building unit 20A provided with a roof 4 on the upper side includes an upper side of an intermediate position in the axial direction of the opposing upper beam 22 or the building. A portal frame 30 having a pair of bundle columns 31 fixed on the upper side of the columns 21 facing the outdoor side of the unit and a connecting beam 32 for connecting the upper ends of these bundle columns is provided. The window sash 6 is supported by the frame.

  Here, the portal frame is not limited to a single span composed of two (a pair) bundle pillars and a connecting beam erected between these bundle pillars. A plurality of spans composed of two or more connecting beams are also included. That is, as the portal frame, one end of another connecting beam is connected to the opposite side of the connecting beam in one (or both) of the pair of bundle pillars, and the other end of the connecting beam on the opposite side. May be supported by other bundle pillars.

According to the present invention, a gate-shaped frame is mounted on the upper beam or column of a building unit having a normal structure, and the window sash is supported by the gate-shaped frame, so that the building unit having a special structure is not used. A window protruding upward from the building unit can be provided. Therefore, normal equipment can be used as manufacturing equipment and materials for building units, and there is no need to use special transport means for transporting and installing building units to the construction site without causing an increase in manufacturing costs. Since it does not exist, the increase in construction cost can also be prevented.
And by installing a window sash that protrudes upward from the upper end of the building unit, a window with a large height, a window provided at a high position on the wall, etc. can be configured, and the daylighting can be improved. Even when the indoor floor position is increased, the installation position of the window can be increased in accordance with the height of the floor, and a feeling of openness in the room can be ensured.

At this time, in the unit type building of the present invention, an intermediate floor 25 is formed inside the building unit 20A in which the portal frame 30 is provided, and the window sash is formed on the upper side of the intermediate floor. It is preferable that the indoor side is a living room space S5, the lower side of the intermediate floor is a storage space or a blow-off space S3, and the window sash is supported on the upper side of the intermediate floor.
According to this configuration, when the living room space is provided on the upper side of the intermediate floor, the window sash is installed from the upper side of the intermediate floor to the height position corresponding to the ceiling height of the living room space, thereby increasing the height of the window. Can ensure a comfortable living environment. In addition, if the lower side of the intermediate floor is used as the storage space, the storage space can be effectively secured inside the building.
