Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an exterior wall structure that is renovated by attaching dry exterior wall materials to a newly installed rim on an existing exterior wall using special clips instead of nails. It is something.

[Conventional technology]

To renovate the exterior walls of an existing building or house, there are two methods: ■ A structure in which the entire exterior wall is removed and a new wall is formed; ■ A structure in which the existing exterior wall is used as a base and dry exterior wall materials are directly fixed to it with nails; ■The structure was one in which a wooden rim, consisting of a C-shaped channel, was fixed to the existing exterior wall using nails and anchor bolts, and dry exterior wall materials were fixed to this using nails, screws, etc.

[Problem that the invention seeks to solve]

However, the structure (2) had drawbacks such as huge costs, a long renovation period, and the need to stop living in the building. In addition, the structure (2) not only cannot be applied to concrete or the like and has poor workability, but also has the disadvantages of waterproofing, dew condensation, corrosion of fixings due to impermeability, and lack of heat insulation.

Furthermore, since the structure (2) usually uses a C-shaped channel, it was necessary to fix the part of the dry wall material in contact with one edge with tapping screws. As a result, the work efficiency was poor, and there were disadvantages such as the need to drill thick holes, especially for materials such as aluminum that expand due to heat. There was no large gap between them, and the function as an external heat insulating structure was poor.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention provides at least a vertical mounting part for the body rim, a fixed part for fixing the reinforcing/legged layer of the body rim, and a plurality of L-shaped mounting legs fixed to the fixed part. It is formed from a dry type exterior wall material and is attached to the outer edge of the dry wall material using the elasticity of a special lip, which shortens the construction period and reduces costs, and does not require any skill in construction. The present invention proposes a repaired exterior wall structure that can be installed without causing any change in the decorative surface even if it is significantly deformed by heat, such as a metal siding material made of aluminum.
