Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a repaired exterior wall structure in which a dry exterior wall material is attached 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, with the structure (■), the cost is enormous, the renovation period is long, and the residence must be stopped. There were drawbacks such as. 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, in the structure (■), the parts of the dry-type exterior wall material that came into contact with the rim were fixed using tapping screws. As a result, there were disadvantages such as poor working efficiency and the need to drill large holes, especially when the material expands due to heat, such as aluminum.

[Means for solving problems]

In order to eliminate such drawbacks, the present invention has a rim that is approximately U-shaped in cross section, and has locking grooves formed at a predetermined pitch in accordance with the width of the dry exterior wall material on the contact surface that contacts the dry exterior wall material. , which is elastically engaged and slid to hold and fix the fixed part of the dry exterior wall material with clips made of elastic material without detaching, thereby significantly shortening the construction period and reducing costs. In addition, we propose a repaired exterior wall structure that can be installed vertically and horizontally without causing any change in the decorative surface even if it is significantly deformed by heat, like metal siding made of aluminum.
