Abstract

PURPOSE: To improve strength of the whole building, and shorten a construction period of repairing work by installing reinforcing materials from above an existing exterior wall, installing furring strips on them, and installing a new exterior wall material composed of a dry wall material on its furring strips. CONSTITUTION: Reinforcing materials 3 are installed on building frames 1 from outside of an existing exterior wall 2 by fixing tools α such as screws and anchor bolts, and the building frames 1 and the exterior wall 2 are reinforced. The reinforcing materials 3 are installed so as to cross each other, or are connected in a bracing shape to the mutual different building frames 1, and strength can be improved. Next, furring strips 4 are installed on the reinforcing materials 3, and a dry new exterior wall 5 composed of metallic siding or the like is also installed on it in order from below. The exterior wall is repaired without removing the existing exterior wall. Therefore, work is simplified, and cost can be reduced.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a structure for repairing an existing outer wall of a building or a structure with a new outer wall,
More specifically, the present invention relates to an outer wall refurbishment structure in which a new outer wall is formed after improving the strength of a building by arranging an old existing skeleton, a reinforcing material and a furring strip for improving the strength of the existing outer wall.

[0002]

2. Description of the Related Art Conventionally, as this kind of outer wall repair structure,
By removing all old exterior walls and forming a new exterior wall on the existing base material such as the frame and furring strip, directly on the existing exterior wall material, or through a new furring strip or tarpaulin. The structure to attach a new outer wall was common.

[0003]

However, in such a refurbishment structure, it is possible to replace an old existing outer wall with a new outer wall, or to form a new outer wall on a damaged existing outer wall.
It is only the technical idea of hiding the existing outer wall, and the technical idea of reinforcing the existing frame of the old building or the existing outer wall to improve the strength has not been taken into consideration at all. For this reason, the structure of the building after the renovation is burdened, weak in strength, particularly inferior in seismic resistance, new outer walls fall off due to an earthquake, damage to the structure, collapse of the building, etc. Sometimes occurred.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, the present invention provides a method of repairing an existing outer wall with a new outer wall.
A reinforcing material that reinforces the strength of the existing frame or existing outer wall is arranged from above the existing outer wall to improve the strength of the entire building, and a new outer wall is attached to the furring strip attached to the existing outer wall so as to cover the reinforcing material. We propose an outer wall repair structure that forms

It is composed of an H-shaped steel material or other steel frame base (not shown).

As shown in the figure, the existing outer wall 2 is composed of a mortar wall which is constructed by arranging wood slats, a waterproof sheet, a lath sheet and a mortar wall material in this order on the outer surface of the skeleton 1.
Or, provide a furring on the earthed wall or the body 1,
Tarpaulin, metal siding, ceramic siding,
It is composed of ALC panels, tiles, dry wall materials (not shown) such as PVC extrusion siding, and the like.

Reference numeral 3 is a reinforcing material, and as shown in FIG. 2, nails are provided on the existing outer wall 2 through the existing outer wall 2 to the frame 1.
It is attached by a fixing tool α such as a screw screw, a tex, an anchor, and an anchor bolt to improve the strength of the old frame 1 and the existing outer wall 2. It should be noted that one reinforcing member 3 is fixed to at least two or more different skeletons 1 and the skeletons 1 are connected to each other to improve strength.

As shown in FIG. 3 (a), the reinforcing member 3 is made of, for example, a narrow and long thin plate-shaped steel material, wood, a synthetic resin material, or a composite material thereof. As shown in b), it is preferable that the base portion and the eaves portion are continuously arranged all over the circumference of the building at an appropriate pitch.

Reference numeral 4 denotes a furring strip, which is the existing outer wall 2 or the existing outer wall 2.
It is arranged at a proper pitch on the skeleton 1 via the through holes and functions as a mounting base for the new outer wall 5. Also,
The furring strip 4 is provided along the vertical direction when the new outer wall 5 is stretched horizontally, and along the horizontal direction when stretched vertically. Further, by disposing the furring strip 4, an air layer is formed between the existing outer wall 2 and the new outer wall 5, and it is possible to prevent dew condensation by air-cycling this space.

Further, the furring strip 4 is not limited to wood as shown in the drawing, but is also an L-shaped angle bar made of steel, a Z-shaped bar,
It is also possible to use various shapes such as a hat bar.

Reference numeral 5 denotes a new outer wall, which is made of metal siding as shown in the figure, or ceramic siding, vinyl chloride extrusion siding, ALC panel, tile, and the like. Further, the new outer wall 5 is sequentially attached to the furring strip 4 via the fixture α, and further improves the design, heat insulation, soundproofing, waterproofing, fireproofing, vibration resistance, etc. of the outer surface of the building. It is a thing.

Next, a method of constructing the outer wall repair structure according to the present invention will be described. First, as shown in FIG. 2, the reinforcing material 3 as shown in FIG. 3A is arranged and fixed on the existing outer wall 2 made of a mortar wall at an appropriate pitch in succession from the base to the eaves. Then, as shown in FIG. 3B, the strength of the existing frame 1 and the existing outer wall 2 is reinforced.

Then, as shown in FIG. 1, the furring strips 4 are arranged along the vertical direction according to the pitch of the skeleton 1,
It is fixed via the fixing tool α. Further, the new outer wall 5 made of metal siding is sequentially attached to the furring strip 4 by using a fixing tool α such as a nail, and the construction is completed.

[0027]

As described above, according to the outer wall repairing structure of the present invention, a reinforcing material that solves the conventional drawbacks and reinforces the strength of the existing frame or existing outer wall is provided on the existing outer wall. Therefore, the strength of the entire building is improved and the structure is strong against earthquakes. Since it is not necessary to dismantle the existing outer wall, the number of construction steps can be omitted, the construction period can be greatly shortened, and there is no hindrance to living during construction. Since the new outer wall is formed directly on the furring strip arranged on the existing outer wall, the construction is simple and the cost can be saved. It has a double wall structure consisting of an existing outer wall and a new outer wall, and has a structure with excellent heat insulation, soundproofing, and fireproofing. Since the new outer wall is fixed directly to the existing frame, it will not fall off easily. Since an air layer is formed between the existing outer wall and the new outer wall via the furring strip, dew condensation can be prevented by using the air cycle. The furring strip and the new outer wall are also members that improve the strength of the body. There are characteristics and effects.
