Description

  The present invention mainly relates to a method for repairing an outer wall of a steel frame house.

  Conventionally, when renovating the outer wall of a steel-framed house that has been built many years after construction, a method of applying a new coating to the outer wall surface or a method of attaching a new outer wall panel on the existing outer wall panel is known. .

  However, in the method of applying paint, there is a limit to the kind of painting, and not only the design expression is limited, but also there is a drawback that it is necessary to take measures against paint scattering and odor countermeasures in the vicinity during painting work.

  On the other hand, the method of pasting the new outer wall panel on the existing outer wall panel is a state where the existing outer wall panel and the new outer wall panel are overlapped, so that the wall thickness is greatly overhanged, so that the window, shutter, drainer, There is a drawback in that special consideration is required for contact with other exterior members such as bags.

  As a method other than the above, there is a method in which an existing outer wall panel attached to an existing casing is removed and a new outer wall panel is attached to the existing casing. In this case, although the renovation work is larger than the above method, there is no need to consider measures for paint scattering and odor measures in the vicinity, and there is no need for special consideration when dealing with other exterior members. There is.

  However, the specifications of the outer wall panels have changed between the beginning of construction and the present, and the width dimensions of the existing outer wall panel and the new outer wall panel may be different. In such a case, when the new outer wall panel is attached to the existing case to which the existing outer wall panel has been attached, a displacement occurs between the end portion along the vertical direction of the new outer wall panel and the vertical member of the existing case. Thus, there is a problem that a member for supporting the end portion of the newly installed outer wall panel is lost, and the work of attaching the newly installed outer wall panel to the existing housing becomes complicated.

  In particular, since the outer wall panel having a complicated shape is attached to the truss having a complicated shape as disclosed in Patent Document 1, in the wife side outer wall portion of the house, a new outer wall panel is added to the existing truss. The mounting work was more complicated.
