DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction in which a plurality of building units each having a rectangular parallelepiped skeleton are combined vertically and horizontally and extend in the short side direction of the rectangular parallelepiped to divide the interior space of the building units into two. The present invention relates to a unit-type building provided with partition walls and a method of assembling the same.

The building unit is usually composed of pillars erected at the four corners, and ceiling beams and floor beams interconnecting the upper and lower ends of these pillars, and has long sides and short sides having different lengths. It has a rectangular parallelepiped frame having a rectangular planar shape. Floor materials, wall materials, and other necessary equipment members are attached to this framework in advance at a factory. According to such a unit-type building, a floor surface material or the like is attached to the building unit in advance. Therefore, there is an advantage that the construction period at the construction site can be significantly reduced.

When such a unit-type building is used as an apartment house having a plurality of dwelling units therein, a boundary wall having fire resistance is provided at a boundary portion between adjacent dwelling units. Here, the boundary wall is formed by installing a boundary wall panel in which a refractory surface material is attached to a square frame body facing each other (see Japanese Patent Application Laid-Open No. 8-177125). Such a boundary wall panel is designed on the assumption that an installation work on a building unit is performed in a factory.
