DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof having steps, such as an old existing new tiled roof (slate roof, asbestos slate roof, etc.) without removing the existing new tiled roof. It relates to a renovable roof renovation structure.

[0002]

2. Description of the Related Art In general, the renovation of a roof having steps such as an existing new tiled roof (flat tile) such as asbestos slate roofing material is performed by
After removing all existing new tiled roofs, or after placing rafters on existing new tiled roofs as new groundwork and forming a new groundwork with a baseboard laid on it, lay a new roof It was either structure. As another conventional structure, as shown in FIGS. 7A and 7B,
On the existing roof base α as shown in FIG.
As shown in FIG. 7B, the back material C is laid, and the roof material A is fixed by the fixing tool β as shown in FIG. 7B.

[0003]

However, in order to remove the existing new tiled roof and form a new roofing material, it is necessary to stop living for a long period of time, and the new tiled roof which has become waste And the total cost of renovation was enormous. In addition, if a new foundation is formed on an existing new tiled roof and a new roofing material is laid on it to renovate the roof, there is no need to stop living, and it will be significantly improved from the above. Although the construction time is long, the construction period is long, the necessary members are increased, and the cost is inevitably increased. In addition, special members for installing keraba, eaves, etc., and soundproofing materials must be added. In addition, asbestos slate roofs are vulnerable to external pressure, and the rafters do not evenly contact the overlapping areas, resulting in a lack of stability and damage to the overlap of the existing new tiled roof during renovation. In addition, as shown in FIG. 7 (b), a step γ is formed in the roofing material A, and a space a is formed between the backing material C and the existing roof foundation α. When people rise,
There was a disadvantage that the roofing material A was deformed (damaged).

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks, the present invention relates to a structure for repairing an existing roof base comprising a roof having an existing step, wherein a male-female connecting structure is provided at a side edge in a width direction. It is intended to provide a roof renovation structure in which a roofing material having a cushioning core material formed on the back surface of a roofing material formed on the existing roof foundation is provided.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a roof repairing structure according to the present invention. 1A is a cross-sectional view showing a construction state of a renovation structure of a new tiled roof according to the present invention, FIG. 1B is a cross-sectional view showing a roofing material A, and FIG. It is sectional drawing which shows the construction state of a structure. A is a roof material, B is a surface material, C is a back material,
D is a core material, α is an existing roof base, β is a fixture such as a nail, γ is a step, and a is a space.

As shown in FIG. 2, the existing roof base α is a rafter 1, a frame made of a ground board 1a, a waterproof sheet 2 (indicated by a two-dot chain line), and a roof 3 having a step γ. It consists of a wooden foundation composed of: Of course, as the frame of the existing roof base α, H-shaped steel, I-shaped steel, grooved steel, lightweight grooved steel, lip grooved steel, equilateral angle steel, unequal angle angle steel, square steel (square pipe), circular steel ( It is also possible to use a steel frame substrate using a circular pipe).

The new tile roof 3a is a flat tile such as a cement slate roof and an asbestos slate roof manufactured by autoclaving cement mixed with various minerals.

The new tiled roof 3a is an existing roofing material. The roof is damaged due to deterioration of aesthetics due to aging, the occurrence of rain leaks, or the like. The desired roof, etc.

The roof material A has a cross section in the width direction as shown in FIG. 1 (b), and the surface material B is made of, for example, a metal plate (color steel plate, copper plate, aluminum plate, titanium plate, stainless steel plate, sandwich steel plate). , A clad steel plate or the like), or a synthetic resin (plastic) or the like by roll forming, press forming, extrusion forming, or the like.

[0010] More specifically, the roofing material A is in the shape of a long plate, and the surface material B has one side edge in the width direction below the decorative surface 4.
That is, it is bent in a substantially U-shape on the back surface 5 side, and the step decorative surface 6 is formed.
And a male connecting portion 9 formed with an insertion edge 7, wherein a substantially U-shaped hooking groove 8 is formed from the decorative surface 4, the step decorative surface 6, and the insertion edge 7.

At the other end of the decorative surface 4, a fitting groove 10 which is bent upwardly of the decorative surface 4 and which fits into the insertion edge 7 having a substantially U-shaped cross section, Forming a fitting edge 11 whose tip is folded back into a U-shape, and a fixing piece 12 which is bent downward at the tip of the fitting edge 11 and bent outward in an L-shape substantially parallel to the decorative surface 4 to form an extension. The female connector 13 is formed.

The back material C is a metal material, asbestos paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb, Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper , Glass fiber non-woven fabric or the like, or a laminate of two or more kinds, or a sheet made of a waterproof treatment, a flame retardant treatment, or the like.

As the core material D, polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam (PEF),
A foam made of a synthetic resin foam such as a polystyrene foam or a urea foam, a fiber-based heat insulating material such as glass wool or rock wool, or the like, or a composite material of these.

Since the core material 3 is a material having cushioning properties (elastic deformation or plastic deformation), the roof material A
When fixing on the existing roof base α, the existing roof base α
The core material 3 is deformed in accordance with the step γ of the (newly-built tiled roof 3a) and is fixed in a state of closing the space a. Therefore, defects such as a decrease in heat insulation and a deformation (breakage) of the roofing material A when a person climbs on the roofing material A are eliminated.

The core material 3 has cushioning properties, but the roof material A
After the construction, the cushioning property is lost due to the contraction of the core member 3 due to the fixing force of the fixing member β, and the deformation is minimized by the external force of the roofing material A.

What has been described above is an embodiment of the roof renovation structure according to the present invention. The roofing material A as shown in FIGS. it can.

3 (a) to 3 (h) show a decorative material 4 and a roof material A in which a core material D is deformed.
(H) is the roofing material A from which the backing material C is deleted.

FIG. 5A shows a structure in which a waterproof sheet 2 is formed on an existing roof base α, and FIG. 5B shows a structure in which a roof material A without a back material C is applied.

FIG. 6 shows a structure in which the roofing material A without the backing material C is applied and the waterproof sheet 2 is formed on the existing roof foundation α.

[0020]

As described above, according to the roof repairing structure of the present invention, a new roofing material can be constructed without removing the existing roof base. There is no need to form a new roof base. Deformation (damage) of the roofing material and damage of the waterproof sheet can be prevented. In addition, since the roof material is formed by fitting the roof material to the existing roof base, heat insulation, waterproofness, airtightness, soundproofing, wind pressure resistance, and the like are improved. There are features and effects such as.
