[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure for repairing an existing outer wall surface of a building or a structure with a new outer wall. More specifically, an existing old frame and a reinforcing plate for improving the strength of the existing outer wall surface are provided. The present invention relates to a refurbished structure in which a new outer wall made of drywall material is formed on the surface after improving the strength of the building.

[0002]

[Prior art]

 Conventionally, this type of outer wall renovation involves removing all existing old outer walls and forming a new outer wall on the existing base material such as the frame and furring strip, or directly on the existing outer wall material. Or, it was a general structure to attach a new outer wall through a new furring strip or a waterproof sheet.

[0003]

[Problems to be solved by the device]

 However, such renovation is only the technical idea of replacing the old outer wall with the new outer wall, or forming a new outer wall on the damaged existing outer wall to conceal the existing outer wall. The technical idea of reinforcing the existing frame or existing outer wall of an old building to improve its strength was not taken into consideration at all. For this reason, the structure of the building after the renovation is burdened, weak in strength, particularly inferior in earthquake resistance, and new outer walls fall off due to earthquakes, damage to the structure, collapse of the building, etc. Sometimes occurred.

[0004]

[Means for Solving the Problems]

 In order to eliminate such drawbacks, the present invention connects the base, girder, ridge girder or girder that constitutes the existing skeleton by connecting the existing skeleton before the renovation of the existing outer wall with the new outer wall. Two or more metal strip-shaped reinforcing plates to be reinforced are installed diagonally across from the existing outer wall surface and fixed to the existing frame to improve the strength of the entire building, and at the same time, the new outer wall is covered to cover the reinforcing plate. It proposes a repair structure for the formed outer wall.
