Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit-type house, and more particularly, to a unit-type house in which a plurality of building units, each having a temporary column in one corner, are combined around the temporary column to secure an indoor space. Regarding

[0002]

BACKGROUND ART A unit-type house constructed by combining a plurality of box-shaped building units has been conventionally known. Further, as one of the construction methods for constructing this unit-type house, there is a construction method that secures a wider indoor space by removing a pillar that should originally be arranged in the center of the indoor space. More specifically, after a plurality of building units in which temporary columns are temporarily installed in one corner are connected around the temporary columns, the temporary columns are removed from the corners that are the connecting portions to secure an indoor space without columns.

[0003]

By the way, in a house constructed by this construction method, due to its structure, a bending (stress) occurs at the connecting portion where the temporary column is temporarily installed. Therefore, various measures have been taken to prevent the concentration of stress that causes the bending by providing a reinforcing beam or the like that straddles each building unit in order to suppress the bending that occurs in the connecting portion. An object of the present invention is to provide a unit-type house that can further suppress the influence of bending caused by removing columns from the indoor space.

[0004]

In order to solve the above problems, the present invention has the following configuration. That is, the unit-type house of the present invention is a room without a pillar formed by connecting a plurality of building units in which a temporary pillar is temporarily installed at one corner around the temporary pillar, and then removing the temporary pillar from the corner portion that is the connecting portion. In a unit-type house that secures a space, at least one of the ceiling surface and the floor surface of the connection portion where the temporary columns are temporarily installed has an opening portion formed between the building units, and the opening portion is formed in the opening portion. Is characterized in that a panel for closing the opening is provided.

The size of the opening may be set so that the beam of each building unit faces the inside thereof. A wooden frame supported by the beams of the building units may be provided at the edge of the opening, and the panel may be fixed in the opening through the wooden frame.

Further, it is possible to adopt a structure in which a reinforcing tape is attached to the boundary between the opening and the panel in a state where the panel is provided in the opening. Further, a wallpaper may be provided on the front surface side of the panel.

According to the unit-type house of the present invention thus constructed, an opening extending over each building unit is formed on at least one of the ceiling surface and the floor surface of the connecting portion where the temporary columns are temporarily installed. Therefore, the concentration of stress acting on the ceiling surface or the floor surface, which is the connecting portion, is avoided by the opening. Moreover, since the panel is provided in the opening, the step between the building units, that is, the construction error is apparently minimized. Further, when the wallpaper (cloth) is attached, the extension of the wallpaper at the connecting portion is also suppressed.

Further, if the panel is fixed via the beam of each building unit and the wooden frame supported by the beam, the panel can be more surely supported in the opening. Further, if a reinforcing tape is attached on the boundary between the panel and the opening, the joint between the panel and the opening is covered with the reinforcing tape,
It is easy to obtain a sense of unity between the panel and the ceiling surface or the panel and the floor surface. Further, the extension of the wallpaper on the boundary line is also suppressed by the reinforcing tape.
