Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for repairing an existing wall of a building or a structure with a new wall.

[0002]

2. Description of the Related Art Conventionally, as this kind of outer wall repair structure,
By removing all the old outer walls that have become old, a new outer wall is formed on the wall base material such as the existing frame or furring, or directly on the existing outer wall material, or by installing a new furring or tarpaulin. The structure in which a new outer wall is attached via a general structure was common.
There was also a structure in which a furring strip was fixed on an existing wall with a fixture such as a concrete anchor bolt, and a new wall was fixed to this furring strip for repair.

[0003]

However, in such a repair structure, the existing outer wall is removed, so that there is a drawback that the residence is interrupted during the repair work. In addition, the cost of the operation of disposing of the removed residual material of the existing outer wall is high, and the construction becomes large in scale, which may adversely affect people and the surrounding environment. In addition, in the refurbishment structure like this, since the existing wall is an inorganic wall, the fixture to fix the furring must be a concrete anchor bolt type fixture, and the construction order is to drill on the existing wall. Etc. to open the pilot hole, then drive the anchor and fasten the bolt to the anchor 3
It requires a stepwise procedure and has the drawback of being extremely inferior in workability.

[0004]

In order to eliminate such drawbacks, the present invention has a repair structure in which an existing wall is left as it is and a new wall is formed on the existing wall via a furring strip.
It is possible to live even during construction, no waste material is generated, cost can be kept to a minimum, and moreover, needle-like fasteners can be driven diagonally into the existing wall from above the furrow. Since the fixing strength (tensile force) can be improved and the furring strip can be fixed to the existing wall, the furring strip can be fixed in one procedure, and an outer wall repair structure having excellent workability is proposed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an outer wall repairing structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is an explanatory view showing a typical example of the above-mentioned repair structure, which is composed of an existing inorganic wall A, a furring strip B, a new wall C, and a fixture α.

The existing wall A is made of an inorganic material formed on an existing skeleton (not shown), for example, a mortar wall, a concrete wall, an ALC wall, a slate wall, a ceramic panel wall, etc. Of one or more types.

The furring strip B is attached to the existing wall A by a fixing tool α, and also functions as a mounting base of a new wall C described later, eliminating irregularities due to the surface pattern of the existing wall A, and the rising of the new wall. It is flat and improves aesthetics.

The shape of the furring strip B is, for example, an elongated body having a rectangular cross section as shown in FIG. As its material, various kinds of wood B1 as shown in FIG.
Alternatively, a composite material of wood B1 and various synthetic resin foams B2 as shown in FIG. 2 (b) can be used.

Further, as shown in FIG. 1, the furring strip B is along the vertical direction when the new wall C is a horizontally stretched wall material, and the new wall C is a vertically stretched wall material. In some cases, the existing wall A is continuously run at a fixed arbitrary pitch along the horizontal direction.
It is arranged on the entire surface and is fixed at an appropriate pitch by a needle-shaped fixing tool α.

As the needle-shaped fixture α, for example, screw screws, tex, hex, etc. other than the nails shown in the figure are used. Then, the fixing of the furring strip B to the existing wall A by the fixing tool α is driving in an oblique direction from the horizontal plane as shown in an enlarged view in FIG.

More specifically, as shown in FIG. 4 corresponding to the sectional view of FIG. 3, the fixture α is driven into the existing wall A at an angle of θ with respect to the horizontal line 1 indicated by the alternate long and short dash line. By driving the fixing tool α in an oblique direction, the frictional resistance between the fixing tool α and the existing wall A is increased with respect to the pulling force in the direction indicated by the arrow, which is improved. The connection force and integration can be strengthened.

In the upper part, the fixing tool α is tilted upward, and in the lower part, the fixing tool α is tilted downward, so that the vertical fixing directions are alternately reversed and fixed. Of course, if the angle θ is in the range of about 15 to 75 degrees (for example, 30 degrees, 60 degrees, etc.) other than 45 degrees, the connecting force is sufficiently strengthened.

In FIG. 4, the fixture α is tilted in the vertical direction. Of course, as shown in FIG. 5, the fixture α is tilted by an angle θ from the horizontal line 1 shown by the two-dot chain line. , The head α2 of the fixture α may be present at the circumference 2 (indicated by a chain double-dashed line) of the conical bottom surface generated when the head α2 of the fixture α is rotated with the tip α1 of the fixture α as the apex. If
It may be tilted in any direction (vertical, horizontal, etc.).

The new wall C is a metal siding material, a ceramic siding material, a vinyl chloride extruded siding material,
It is made of a dry board type outer wall material such as an ALC panel, a tile, a metal panel, etc., and in particular, as shown in FIG. 6, a surface material 3 made of a metal thin plate and a back material 4 made of a metal thin plate or a sheet-like material. Therefore, the metal siding sandwiching the core material 5 made of synthetic resin foam or gypsum board or the like is preferable because it is lightweight, has excellent strength, and is easy to construct.

The new wall C is sequentially fixed on the furring strip attached to the existing wall A by a fixing tool α such as a nail to improve the surface design of the building, the primary waterproofing and the heat insulating function. Is. Of course, the new wall C may be fixed by inclining the fixing tool α at an angle θ.

Next, a method of constructing the outer wall repair structure according to the present invention will be briefly described. First, the furring strip B made of wood B1 as shown in FIG. 2 (a) is fixed to the existing wall A by driving a fixture α made of nails diagonally as shown in FIG.
This work is performed at an appropriate pitch, and a furring strip is arranged on the entire surface of the repaired wall as shown in FIG. Finally, the new wall C made of metal siding is sequentially fixed to the furring strip B to complete the construction. Of course, draining material, torch material, projected corner material, entering corner material,
