Description

The present invention relates to a building extension method using a framework wall structure (hereinafter referred to as “ building extension method using a framework wall structure ”) .

  In recent years, the number of buildings has been increased for the reasons that the durability of the buildings has improved and the buildings can be shared between generations.

  For these reasons, various methods for extension of buildings have been proposed (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 06-57966

  However, in such a conventional building extension method, the target building is a building having a frame structure that mainly supports the load of the building body with column beams.

  On the other hand, buildings with a framed wall structure (so-called two-by-four buildings) that mainly support the load of the building body with walls are often implemented due to advantages such as superior seismic performance compared to buildings with a frame structure.

  Nonetheless, I have not heard of an extension method that can accommodate buildings with this framework wall structure.

  Accordingly, an object of the present invention is to provide an extension method that can be applied to a building having a framed wall structure.

  In order to achieve the above object, the method for extending a building with a frame wall structure according to the present invention is a method for extending a building with a frame wall structure, in which an existing wall surface of the building is provided with an opening communicating with the extended portion. An additional foundation is continuously placed on the ground of the extension part of the building, and at least two vertical members are erected on the additional foundation, and a horizontal member is installed between the vertical members. And the horizontal member is fixed to an upper portion of the portion that becomes the opening of the building, and then the opening is provided.

  Here, after placing the additional foundation, a floor panel frame member may be installed on the upper surface of the additional foundation, and the vertical member may be erected on the upper surface of the floor panel frame member.

  The vertical member may be a sleeve wall panel frame member.

  Furthermore, the horizontal member may be a structural beam.

  In such an extension method of a building using the frame wall structure of the present invention, when an opening communicating with the extension part is provided on the existing wall surface of the building, an additional foundation is made continuous with the existing foundation on the ground of the extension part of the building. At least two vertical members are erected on an additional foundation, a horizontal member is installed and supported between these vertical members, and the horizontal member is fixed to the upper part of the building opening. Then, the opening is provided.

  Because of this structure, the horizontal member supported by the vertical member can support the load on the upper part of the opening of the extension of the building, so a building with a framed wall structure that could not be handled by the conventional method of building extension It can correspond to the extension of the.

  Here, after placing the additional foundation, when the floor panel frame material is installed on the upper surface of the additional foundation and the vertical member is erected on the upper surface of the floor panel frame material, the floor of the extension part can be easily constructed. In addition, the vertical member that supports the horizontal member can be erected firmly and easily so that the horizontal member can support the load on the upper part of the extension part of the building.

  In addition, when the vertical member is a sleeve wall panel frame material, it is not necessary to retrofit the sleeve wall panel frame material particularly when expanding a relatively small space such as expanding the bathroom or providing a storage space. Workability is good.

  Further, when the horizontal member is a structural beam, the ceiling portion of the extension part can be easily provided so as to ensure durability and waterproofness by connecting to the structural beam, and the workability is good.
