Field of the Invention The present invention relates to a connecting structure of a building unit for connecting two building units arranged side by side in a horizontal direction and a connecting structure of a building unit for connecting two building units stacked vertically.

[0002]

2. Description of the Related Art In recent years, in order to increase the rate of industrialization and shorten the construction period on site, box-shaped building units manufactured in advance in a factory are transported to the site, and these building units are assembled on a foundation at the site. The unit construction method used is often used. A building unit used in this unit construction method is manufactured by assembling a ceiling surface material, a wall material, and the like in a framework including columns and beams, and is arranged at a predetermined position on a foundation at a construction site. After this, a ceiling joint panel that straddles these two building units is placed between the ceiling panels of the two building units that are horizontally adjacent to each other.
The ceiling panels were connected to each other. Similarly, a wall joint panel connecting the wall materials is installed between the wall materials of the adjacent building units to connect the wall materials.

[0003]

However, in order to improve the heat insulation and airtightness of the joint between the two building units by using the ceiling joint panel and the wall joint panel, the ceiling joint panel, the ceiling panel, and the wall joint are required. The panel and the wall material had to be joined together in an airtight manner, and the joining work on the construction site, such as processing for site adjustment, was complicated.

[0004] It is an object of the present invention to provide a connecting structure of building units that can ensure heat insulation and airtightness at a joint portion between two building units without requiring any special operation.

[0005]

The present invention will be described with reference to the drawings. The present invention relates to a connecting structure of building units for connecting two building units 10 arranged side by side in a horizontal direction, wherein the building units are four-sided. Pillars 21, these four pillars 21
And a lower beam (24, 25) connecting the lower ends of the four pillars, and a ceiling surface mounted on the upper part of the frame. Material 31 and between the two building units,
A ceiling joint panel 41 that connects the ceiling panels of each building unit is installed across these building units, and between the upper beams of the building units facing each other on the upper surface side of the ceiling joint panel. It is characterized in that a ceiling heat insulating material 42 extending over the upper beam is provided.

In the present invention, since the ceiling heat insulating material is installed across the upper beams facing each other between the two building units, the ceiling heat insulating material is installed together with the ceiling joint panel between these upper beams. Therefore, sufficient heat insulation and airtightness can be ensured at the joints of the building units without any special work. In addition, if a low-density material such as a porous material is used as the ceiling heat insulating material, sound absorption is high, so that the sound insulation of the joints of the building units can be improved. Further, since the ceiling heat insulating material is disposed over the upper beam, the ceiling heat insulating material can be easily installed without interfering with the ceiling face materials assembled in the framework and the ceiling joint panel connecting them. When installing the ceiling heat insulating material, if one end is fixed to the upper surface side of the ceiling surface material of one building unit in advance, after the building unit is arranged, the other end side is put on the upper beam of the two building units from above.

[0009] The above-mentioned sound insulation sheet may be interposed between the ceiling joint panel and the upper beam.
It is desirable to be interposed between the ceiling insulation and the upper beam.

In this way, the sound insulation sheet can be easily constructed simply by sandwiching it between the ceiling heat insulating material and the upper beam.
Also, since the sound insulation sheet is located above the upper beam,
Since there is no risk of being exposed and the dimensions do not have to be strictly formed, it can be easily manufactured. Furthermore, since the sound insulation sheet can be installed from above the upper beam together with the ceiling insulation,
Installation is easier than mounting from below.
