Further, the structure of (3) is not only difficult to apply to concrete or the like and is inferior in workability, but also has disadvantages such as waterproofness, dew condensation, corrosion of a fixture due to impermeability, and lack of heat insulation.
Further, in the structure of (3), the dry outer wall material is fixed by tapping screws at the portion in contact with the furring strip. As a result, the work efficiency is poor, and there is a disadvantage that it is necessary to form a large fool hole especially when the expansion is large due to heat such as aluminum. Therefore, a structure for fixing the dry outer wall material by using a slidable clip on the furring strip has been developed. However, in this case, the dry outer wall material also slides at the same time as the clip.Therefore, the dry outer wall material must be molded precisely in order to make the joints of the dry outer wall material with a fixed joint width when connected to each other. I had to do it. That is, when the dry type outer wall materials are abutted in the longitudinal direction or connected by using an accessory such as a joiner, if a plurality of dry type outer wall materials are arranged, molding errors are accumulated and the joints are not aligned.

できる。等の特徴がある。As described above, according to the repaired outer wall structure according to the present invention,
Since the dry type outer wall material is fixed through the elastic clip that slides easily without using nails, the construction time can be greatly shortened and the cost can be reduced. Since the clip is elastically locked to the furring strip, it merely pushes and engages, and does not disengage. Since the clip has a structure for fixing the dry outer wall material and is fixed to the furring strip, the clip also functions as a positioning stopper for the dry outer wall material and can be fixed without accumulating molding errors of the dry outer wall material. Since the structure is fixed to the furring strip by the elasticity of the clip, the dry outer wall material is prevented from swelling due to the deformation after the construction, and the dry outer wall material can be prevented from coming off. The furring strip acts as a raising material, a ventilation space can be formed between the existing outer wall and the new outer wall, and heat insulation and dew condensation prevention can be achieved. Since the furring strip has a straight shape and a clip that is sandwiched between the furring strips is locked, it can be installed regardless of vertical or horizontal tension. There are features such as.
