DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for horizontal or vertical roofing of a metal roof slab on a roof slab laid on an existing roof.

[0002]

2. Description of the Related Art When rebuilding an existing roof, if all the shingles are peeled off and replaced, it takes a lot of trouble and it is difficult to replace the roof while using the building. Therefore, a method of laying a new roof shingle on an existing roof shingle as it is has been adopted. A thin metal shingle is placed on the existing shingle and a nail penetrates the existing shingle.
When fixing metal shingle to rafters with fasteners such as screws,
Metal shingles can be newly installed without increasing the thickness of the roof.

As shown in FIG. 1, for example, an existing roof is provided with a plurality of wooden boards 2 serving as a roof base along a sloped roof of a main house 1, and rafters 3 are provided between adjacent wooden boards 2. Are provided in the base structure. The existing shingle 10 is made of wood wool 2
It is arranged on the upper side and is fixed to the rafter 3 by the existing screw 11. The existing shingles 10 on the upper and lower tiers are connected to each other by existing hangers 12, and the existing shingles 15 on the eaves side are provided with the existing eaves arabesque 15 by using existing fasteners 16 such as screws and nails. It is stuck to. When laying the new metal shingle 20, a metal shingle used on the eaves side is cut at a construction site to prepare an adjustment plate 24 having a required effective length. The adjusting plate 24 is superimposed on the existing metal roof plate 14 so as to wrap the existing eaves arabesque 13, and the new screw 22
And is fixed to the rafter 3. Newly installed metal shingle 20 on the upper side
Is fixed to the rafter 3 with the new screws 22 after being meshed with the adjusting plate 24 via the new hanging members 23. Similarly, the new metal roof plate 20 on the upper stage side is meshed with the new metal roof plate 20 and fixed to the rafter 3. In addition, as the new metal roofing plate 20, a material which is lined with a foamed resin or the like as a heat insulating / waterproof backing 29 as necessary is used.

[0004]

When the existing roof is laid with the new metal roof plate 20, a new metal roof plate 20 having the same working width L as that of the existing roof plate 10 is required. Therefore, it is required to prepare metal roofing sheets 20 having various sizes according to the existing roofing sheet 10. Also,
Since the new metal shingle 20 is provided so as to cover the joints of the existing shingles 10 and 10 connected by the existing suspension 13, the newly laid metal shingles 20 on the second and subsequent tiers are swelled like a drum. It gives a poor finish. Adjustment plate 2 for eaves side
No. 4 needs to be prepared by cutting a metal shingle according to the dimensions of the existing roof to be constructed. By shifting the overlapping portion between the adjusting plate 24 and the upper-side metal roofing plate 20, cutting processing can be omitted in some cases, but the degree of freedom of construction is reduced by that much. The present invention has been devised to solve such a problem, and by arranging the base material of the new shingle on the existing shingle, the shape and dimensions of the existing shingle are not affected. The purpose is to lay a new roof slab with a high degree of freedom and to build a roof with a good-looking construction finish.

[0005]

According to the roof repair method of the present invention, in order to achieve the object, a new metal rafter is arranged on an existing shingle along an inclined surface of a roof, and a space between adjacent new metal rafters is provided. A panel-shaped foamed resin molded article is laid on the new roof, and the new metal rafter is fixed to the existing rafter with a fastener penetrating the existing roof plate.The lower eaves of the existing eaves arabesque and the new metal rafter and the panel-shaped foamed resin molded article are fixed. After installing the new eaves arabesque so that it wraps around it, fit the lower side of the new eaves arabesque to the new eaves arabesque, fix the upper side to the new metal rafters, and lower the lower side of the upper metal roof plate. It is characterized in that it meshes with a newly-installed metal roof plate on the lower side via a newly-installed suspension, and the upper side is fixed to the newly-installed metal rafter. As the new metal rafter, it is preferable to use a hollow aluminum extruded profile which is lightweight, excellent in strength and corrosion resistance.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In a construction method according to the present invention, a new rafter 31 is formed along an inclined surface of a roof as shown in FIG.
Place it on zero. As the new rafter 31, it is preferable to use a hollow aluminum extruded shape excellent in corrosion resistance and strength in order to reduce the weight on the roof. The new rafter 31 is fixed to the existing rafter 3 with a screw 35 having a leg length reaching the existing rafter 3 or a stopper. An anchor bolt, a screw, a nail, or the like can be used for an existing roof base such as an existing wooden rafter 3, a concrete base, or a hard wood cement board. Between the new rafters 31, a new hard foamed resin molded body 36, which is lightweight and has excellent heat insulation and sound insulation properties, is laid. As described above, when the new rafter 31 and the new hard foamed resin molded body 36 are used in combination, an increase in the thickness of the roof can be suppressed. A new metal shingle 30 is laid on the basis of the new hard foamed resin molded body 36. Since a substantial roof base surface is newly formed by the newly-formed hard foamed resin molded body 36, it is not affected by the shape and the size of the existing roofing sheet 10, and a horizontal roofing or vertical roofing method is used as follows. A new metal shingle 30 can be laid.

In the horizontal roofing method, a new eaves arabesque 37 is first arranged so as to wrap around the lower end of the existing eaves arabesque 15 and the new rafter 31. As the new eaves arabesque 37, for example, an extruded aluminum material that is lightweight and has excellent corrosion resistance is used, and the upper side is fixed to the new rafter 31 with fasteners such as screws 38 and bolts. New metal roof 3 located on the eaves side
4 is fitted to the new eaves arabesque 37, and the upper side of the new metal roof plate 34 is fixed to the new rafter 31 with new fasteners such as screws 32 and bolts. The lower end portion of the upper-side new metal roof plate 30 is engaged with the new metal roof plate 34 fixed to the new rafter 31 via the new suspension element 33. The new metal roof plate 30 is fixed to the new rafter 31 with the new screws 32 on the upper side. Further, similarly, the lower-side new metal roof plate 30 of the upper-stage new metal roof plate 30 is also meshed with the lower-side new metal roof plate 30, and the upper-side side is fixed to the new rafter 31. As the new metal roofing plates 34 and 30, those having a backing 39 such as a foamed resin on the inner surface can be used. In addition, new metal roof plates 34 and 30 in which the suspension 33 is integrated.
Using not only improves workability, but also builds a roof with greater resistance to wind pressure.

In this manner, the new metal roofing plates 30, 34 are mounted on the existing roofing plate 10 in the ridge direction, and the entire roof is laid horizontally. The laid new metal shingle 30 is connected to the existing roof shingles 1 on the upper and lower tiers via the existing hangers 13 as shown in FIG.
The roof plate is not pushed up by the connecting portion of 0 and deformed into a drum shape, and has a flat surface. Therefore, the finish of the construction is good. Further, it is not necessary to cut the metal roof shingle at the work site so that the adjusting plate 24 having the effective working width peculiar to the eaves side is obtained, and the new metal roof shingle 34 having a predetermined length is not required.
Because it can be used on the eaves side, workability is also improved. Moreover, without being affected by the working width L of the existing shingle 10,
Because it can set the working width L ₁ of the new metal roof plate 30, lateral葺又that meet customer needs becomes possible Tate葺.

[0009]

As described above, according to the roof repair method of the present invention, a metal rafter is newly provided on an existing shingle,
A foamed resin molded article is laid between adjacent metal rafters to form a substantially new roof base surface, and a new metal roof plate is laid on the base surface. This laying work is the same as the roofing work for a conventional new house, and cutting work and shape correction at the work site are not required, so that it is possible to lay a new metal shingle with good workability. . In addition, since the laid new metal roof slab does not deform like a drum as in the conventional case, the finish of the construction is good.
