Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an attached structure and an extension structure for expanding the internal space of an existing building using the attached structure.

[0002]

[Prior Art] I want to make my room larger as I can afford my life.
There is a strong demand to make it wider. In addition, a large living space is required inside the building due to the increase in the number of people living together for two generations due to the arrival of an aging society. In this case, in terms of cost or effective use of resources, it is recommended to add or renovate the house instead of rebuilding it.

In response to this, various attached structures and extension structures have been proposed. In Japanese Utility Model Laid-Open No. 58-39948, a member for forming an additional space is formed into a panel such as a sleeve panel, and a mounting frame having a groove structure is used to mount these members on an existing building. The technical idea of using a mounting frame provided with a groove structure for mounting a support pillar for extension is also disclosed in Japanese Patent Laid-Open No. 61-221433.

Further, Japanese Patent Application Laid-Open No. 54-102011 discloses a technical concept of an extension construction method in which each unitized portion of the extension structure portion is assembled in a fixed procedure to obtain an extension space. Further, the technical idea common to the extension is also disclosed in the structures in the unit houses described in JP-A-59-106644 and JP-A-6-42052.

By the way, it has been paid attention that an attached structure such as a sunroom or an accessory room is stored separately from the existing part in order to simplify the construction, and when viewed from the inside, the extension part is added to the existing part. It is difficult to have a feeling that the existing space has been expanded because it is felt. This is probably because interior materials such as inner wall materials are discontinuous from the existing part to the extension part.

[0006]

SUMMARY OF THE INVENTION According to the present invention, an existing structure and an expanded space are integrally continuous as seen from the inside, and an expanded structure that strongly gives the feeling that the existing space is expanded, and such an expanded space can be easily obtained. The challenge is to provide structures.
