る。2. Description of the Related Art In recent years, for example, as shown in FIG. 5, an existing cement-based wall 1 is used to repair a wall by applying a repairing wall material 4a having a metal outer skin. Wall 1
An L-shaped angle material a called "cat" is fixed to the wall surface with bolts, and the angle material a is used to repair the C-shaped steel A
A is supported, and a drainage drain 6a is attached to the repair furring strip Aa, so that the lower part of the repair wall material 4a whose lower end is supported by the repair furring strip Aa is water-removed.

下するという問題があった。By the way, in such a repair structure, an angle member a for fixing the repair furring strip Aa is required separately, and in order to fix the angle member a, a fixing bolt for fixing the angle member a is provided inside the existing wall 1. When hitting the rebar, the position of the angle member a has to be shifted, the workability is greatly reduced, and the repair furring strip Aa supported by the angle member a is moved inside and outside according to the unevenness of the existing wall 1. The position is slid and changed to absorb the irregularities of the existing wall 1, and the outer surface of the repair furring strip Aa is flush with the mounting surface of the other furring strip and bolted. , It is necessary to fix it to the repair furring strip Aa, and the fixing direction is different, which leads to poor workability, and the use of the angle member a makes the existing wall 1 and the repair furring strip Aa different from each other. An unnecessary gap D is required between The outer surface position of use the wall member 4a is that unnecessarily protrude to the outside. Furthermore, drainage 6 with an approximately L shape
In the case of a, the cover c is indispensable on the bottom surface side, a space S for construction is required between the cover and the ground to which the cover c is attached, and the cover c is attached to the existing wall 1 in advance. It is necessary to fix the bracket e.
To fix the wall to the existing wall 1 and cover the bracket e.
There is a problem in that workability is deteriorated also in this point because work for fixing c is required.

The lower end of the vertically long repair furring Ab is placed on the installation piece 6b and fixed to the existing wall 1, and the repair wall 4a is fixed to the repair furring Ab to repair the existing wall. There is a configuration to do.

As a result, there is a problem in that a gap d is formed between the base drainer 6d and rainwater intrudes into this portion in the direction of arrow a, and insects enter the room.
