Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention renovates existing exterior walls formed by building or building exterior walls, for example, mortar walls and tile walls, by applying dry exterior wall materials to the walls or vertically. Related to the exterior wall structure.

[Conventional technology]

Conventionally, Japanese Patent Publication No. Sho 58-17869 is known as this kind of construction method. In other words, the foundation bone is extended vertically on the outer wall covered with the dry outer wall material and extends to the draining end of the existing wall, and the liner material is fixed to the base either directly or horizontally through the mounting base. Then, the starting material was fixed to this liner material, the first step of the new outer wall material was attached, and the outer wall was renovated by sequentially laying.

[Problems to be solved by the invention]

However, in the above method, the flatness and verticality of the existing outer wall are not considered at all, and the outer wall of the house after 3 to 20 years has undergone almost dimensional changes, and the unevenness of the decorative surface is remarkably apparent. If the base for repair is constructed as it is, there are disadvantages such as a new outer wall being curved, construction requiring a lot of time, and detaching after a while after construction.

[Means for solving the problem]

According to the present invention, in order to solve such a drawback, a body edge serving as a reference for verticality and flatness is arranged at a large pitch on a base such as a frame or an existing outer wall, and a hard spacer is provided between the body edge and the base. And a plurality of waist edges are arranged between the waist edges, and a soft film bag is placed between the base and the waist edge to adjust the flatness between the waist edge and the reference waist edge. Inject the plastic foam of the site foam into the bag, form it, apply dry exterior material to the new base with spacers interposed, and create a beautiful appearance even in a house with severe irregularities and between the base and the rim Randomly, the spacer can follow the gap,
In addition, since the desired vertical edge and flatness are always maintained at the desired edge, it is extremely easy to drive the edge of the fuselage onto the groundwork and to install a new outer wall. I do.
