Description

  The present invention relates to a building unit constituting a unit-type building, and relates to a building structure type building unit in which a frame and a column are used to secure the necessary strength of the building.

  Conventionally, for example, as shown in FIG. 8A, a box-type unit building has a building unit 100D as a unit structure, and a plurality of building units 100D assembled at a factory or the like are carried into a construction site and installed. Built in. In order to ensure the required strength, the building unit 100D has a lower beam set framed in a long rectangle with lower beams 11d, 12d, 13a, and 14a and an upper beam framed in a long rectangle with upper beams 15d, 16d, 17a, and 18a. A cubic frame structure is provided, which includes a set and four columns 19d, 20a, 21a, and 22a that are erected at the four corners of the lower beam set and support the four corners of the upper beam. In addition, although not shown in the figure, each surface member of a floor, a wall, and a ceiling is attached to a predetermined portion of each frame configured by framing.

  In a two-story unit type building in which such building units are stacked, a technique of providing windows and balconies on the second floor part has been proposed (see Patent Document 1). In this unit type building, a large opening is formed in the outer wall by joining a balcony unit to the wall surface of the building unit on the second floor.

  However, since such a building unit has four pillars 19d, 20a, 21a, and 22a as shown in FIG. 8A, two or more adjacent wall surfaces 32a, as shown in FIG. When a large opening 70D extending over 33a is formed, the corner column 19d is exposed. Therefore, a large opening cannot be formed in the corner portion. Further, if the pillar 19d is removed, there is a problem that the required strength of the building cannot be secured, and in particular, the building units cannot be stacked.

Therefore, like the building unit 100E which omits the floor, wall, and ceiling members in FIG. 9, a reinforcing column 90E is provided between the lower beam 12e and the upper beam 16e on the side of the building unit, By installing reinforcing columns 90E ′ between the lower beam 11e and the upper beam 15e so as to avoid the openings, it is possible to maintain a certain level of strength even if the column at the corner portion is removed. As shown by the alternate long and short dash line, a method of providing a large opening 70E extending over two or more adjacent wall surfaces can be considered.

  However, in the method of installing the reinforcing columns 90E and 90E ′ described above, when the building unit 100D is stacked on the upper floor as shown in FIG. 10, the reinforcing columns 90E and 90E ′ on the first floor and the column 19d on the upper floor corner portion are used. Are not installed on the same axis and have a deviation, so that the strength for supporting the weight of the upper floor is insufficient and the structure is unstable. Further, as shown in FIG. 11, when the building unit 100C having the lower beams 12c and 14c and the upper beams 16c and 18c shorter than the upper beams 16e and 18a of the building unit 100E are stacked on the upper floor, The reinforcing pillars 90E and 90E 'and the upper floor corner column 19c are not installed on the same axis, and the first floor corner column 22a and the upper floor corner column 22c are not installed on the same axis. For this reason, there is a problem that the strength for supporting the weight of the upper floor is insufficient and the structure is unstable.

  In view of the above problems, an object of the present invention is to provide a building unit that can ensure necessary strength even when stacked, and that a pillar is not exposed to the outside even if an opening is provided in a corner portion. .

The present invention is a building unit that can be stacked, and is disposed along the upper and lower edges of the outer wall of the corner region so as to support the main frame having a frame structure and the outer wall of the corner region where the opening is provided. An auxiliary frame supported by the main frame in a cantilevered manner and an outer wall attached to the outside of the main frame and the auxiliary frame. The outer wall has an opening in the corner area, and the column is arranged to be shifted from the opening. It is characterized by being.
Here, the “frame structure type building unit” refers to a building unit in which beams and columns are framed, and necessary surface members are attached to positions on the floor, wall, and ceiling, respectively.

  The auxiliary frame is configured in an L shape so as to follow one short wall surface of the building unit and a part of one long wall surface adjacent to the short wall surface, or both of the short wall surface of the building unit and the one adjacent thereto. It is desirable to form a U-shape along a part of the long wall surface. The main frame is preferably configured in a substantially rectangular parallelepiped shape.

  According to the present invention, when the same building unit is stacked, the main frame made of a frame structure ensures the structural strength of each building unit, and the main frame pillar on the first floor and the main frame on the upper floor Since the pillars are installed on the same axis, the necessary strength of the entire unit type building can be secured. Further, the pair of upper and lower auxiliary frames are supported in a cantilever manner, and there are no columns between them. Therefore, even if an opening is provided in the corner portion of the outer wall, the columns are not exposed outside.

  If an L-shaped auxiliary frame is used, the pillars are not exposed to the outside even if openings corresponding to the two side surfaces are provided. Further, if a U-shaped auxiliary frame is used, the pillar is not exposed to the outside even if openings corresponding to the three side surfaces are provided. Furthermore, if the main frame is configured in a substantially rectangular parallelepiped shape, the required strength can be effectively ensured.
