Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an exterior wall renovation method.

[Conventional technology]

When finishing the walls of buildings, exterior wall materials such as tiles are often applied, but over many years, the tiles tend to peel off, creating a very dangerous situation.

To repair such walls, you can partially replace the old tiles with new tiles, or replace the tiles over the entire wall, but in either case, it takes a lot of time and effort. This results in high costs.

Therefore, in the past, a method was adopted in which the old tiles were left as they were and new exterior materials such as metal panels were placed on top of them at regular intervals.

[Problem that the invention seeks to solve]

Therefore, in the conventional method, the fallen tiles accumulate in the gap between the wall surface and the new exterior material, causing damage to the exterior material and the tiles falling from the gap, which is extremely dangerous.

An object of the present invention is to solve these conventional problems and provide a method for renovating an exterior wall without worrying about tiles falling off.

[Means for solving problems]

The exterior wall renovation method of the present invention covers the exterior wall surface with a protective tensioning member made of a sheet-like body such as a wire mesh, and presses the protective tensioning member against the exterior wall surface using a plurality of vertical members. Then, attach the new exterior wall panel to the vertical member.

[For production]

According to the method of the present invention, the outer wall surface is coated with a protective tensioning member, the protective tensioning member is held in a pressed manner on the outer wall surface by a plurality of vertical members, and a new Since the outer wall panel is attached, there is no possibility of peeling of the outer wall material or damage of the new outer wall panel due to the peeling, as in the conventional case, on the outer wall surface on which the outer wall material is disposed.

〔Example〕

Hereinafter, the present invention will be explained in detail based on drawings showing examples.

FIG. 1 shows a cross-sectional view of a wall renovated by the method of the invention. That is, it is a sectional view of a state in which a new exterior wall panel 4 is attached to an old exterior wall surface 3 between windows 1 and 2 arranged above and below. The outer wall surface 3 is formed by disposing a large number of outer wall materials 6 such as tiles on the frame 5 between the upper and lower windows 1.2.
