Description

  The present invention relates to a space remodeling method and a space remodeling structure for a residential building in which a ceiling portion of a lower-floor residential part of a wooden existing residential building is raised to expand a residential space of the lower-floor residential part in the vertical direction.

  In recent years, with regard to residential buildings with two or more stories, residential buildings have been designed to provide a sense of openness by changing the interior space of the building and to provide a large storage space that is easy to use. When building a new building, various floors were developed by partially shifting the floor of each floor up and down to create an open atrium with a high ceiling and a storage cabinet with a low ceiling. (For example, refer to Patent Document 1).

On the other hand, remodeling that remodels the space inside an existing residential building is frequently performed according to changes in the lifestyle of residents living in residential buildings, changes in the number of residents, and the like (for example, Patent Document 2). And Patent Document 3).

  However, the conventional method of remodeling the interior space of an existing residential building is mainly intended to modify the floor plan, and the floor of each floor of the building is shifted up and down and re-installed. For example, it is difficult to meet the demand to newly provide a living part having a high ceiling height and an open space in an existing residential building by renovation.

  As a method of newly providing a living part with a high ceiling in an existing residential building, a part of the upper floor support beam is removed, and the upper floor member and lower floor supported by the floor support beam are removed. By removing the ceiling member and forming an opening, it is conceivable to provide an atrium from the lower floor to the upper floor, but especially in the case of wooden residential buildings, when the floor support beam is removed, The horizontal rigidity of the building may be reduced. In addition, without removing the floor support beam, the ceiling member of the lower floor supported by the floor support beam is placed as close as possible to the floor member of the upper floor, thereby raising the ceiling of the lower floor and It is conceivable to increase the ceiling height of the part, but the height that can raise the ceiling by this is only about 100 mm, so it is not possible to give the lower floor living part a sufficient open feeling, and the upper floor This tends to be an obstacle when installing equipment piping or the like between the floor member of the floor and the ceiling member of the lower floor.

  The present invention has been made by paying attention to such a conventional problem, and maintains an open lower-floor residential part with a high ceiling height and an open structure in a wooden existing residential building while maintaining the desired horizontal rigidity of the building. An object of the present invention is to provide a space reforming method and a space reforming structure for a residential building that can be efficiently provided.
