Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method of constructing a parting wall in an attic mainly used in a condominium.

In conventional technical apartment houses, it is necessary to create fireproof divisions between each house, not only at the parting walls of the rooms but also at the attics. Generally, such fireproof divisions are constructed by pasting fireproof boards such as gypsum board on the parting wall, but in the past, the east side etc. were placed on the parting wall after constructing the roof frame. After the groundwork is constructed, such fireproof boards are attached to the surface by nailing or the like.

Problems to be Solved by the Invention As mentioned above, in the past, all construction work was done on-site, which required detailed work in a narrow attic, increasing the number of work hours and lengthening the construction period accordingly. There were some inconveniences. In particular, a construction method is used in which panels are fabricated in advance with field boards pasted on the surface of a triangular roof frame, and these panels are transported to the site and installed. As a result, the space in the attic was very small and dark, and in the summer it became extremely hot, making work even more difficult. Furthermore, since the ceiling of the alcove was lower than that of the other rooms, the structure was different in this area, increasing the number of parts and making the work even more complicated.

The present invention has been made with the object of eliminating the drawbacks of such conventional construction methods for alcove parting walls.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a method for constructing a parting wall in an attic by installing preformed parting wall panels on the parting wall. Correspondingly, the present invention is characterized in that an expansion panel is attached and installed in advance at the lower end of the parting wall panel.

In this invention, the parting wall panel includes not only a parting wall panel including an extended frame portion with a fireproof plate attached in advance, but also a parting wall panel including only a frame in front of the expanded frame portion.

Example Fig. 9 shows the construction status of the parting wall in the example. In the figure, (1) is the wall, and this wall (1)
