DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing material for tile-roofing and vertical roofing, and more particularly, to simultaneously and integrally fulfill a waterproof function, a protective function and a decorative function. The present invention relates to a roofing material for tile rod roofing and standing roof roofing, which simultaneously and integrally satisfies the functions of heat insulation and sound insulation.

[0002]

2. Description of the Related Art FIG. 13 is an external perspective view including a partially broken cross section of a roof using a conventional tile rod roofing material, FIG. 14A is an enlarged perspective view of components of a joint portion, and FIG. () Is an enlarged side sectional view of the joint after completion of the construction. 13 and 14
As shown in (A) and (B), a roof using a tiled roofing material for a general house or the like is obtained by fixing a base plate 102 on a purlin material 101, pasting an asphalt roofing 103 thereon, and forming a roof. Roof roofing material 1 made of metal rectangular tiles along the slope
04, and the roof 105 is sequentially roofed with a gap between the hanging elements 105.

[0003] Next, a hook 105 is inserted through the gap, and further through a core 106, a nail 107 is used for the field board 1.
02 and the purlin 101 are nailed and fixed, and further covered with a cap 108, and both ends of the cap 108 are bent inward to complete waterproofing, and are sequentially roofed. 109 is an eaves arabesque.

By the way, in the conventional construction method, it is necessary to perform waterproofing work (for example, asphalt roofing 103) on the groundwork before performing the roofing work, and the roofing work and the waterproofing work are performed completely independently. Was. Here, the purpose of the waterproofing work is to secure the waterproofing function, and the purpose of the roofing work is to make the appearance beautiful together with the prevention of rain leakage and the protection of the building and the waterproof layer (protection and makeup function).
When performing the roofing work, holes are made in the waterproof layer completed by the waterproofing work, and anchor screws, nails, and the like are driven in to fix the metal sheet roof material.

[0005]

However, if the waterproofing work and the roofing work are performed independently as described above, holes are formed in the waterproof layer once completed, so that the waterproof function becomes insufficient. As a result, there is a risk that rain will leak from the roof due to aging. Further, if the waterproofing work and the roofing work are independent constructions as in the conventional construction method, the construction cost related to the roof tends to be bulky and the construction period tends to be long.

Further, a gap may be formed between the nail 107 and the purlin 101 and the asphalt roofing 103 due to aging or salt damage, and rainwater or the like may leak into the attic. In addition, since the conventional roofing material of a tile rod has many joints, a large amount of rain leaks from the joints. This tendency of leaking is remarkable especially at a portion where a roof gradient is gentle, a ridge portion, a valley portion, a curved surface portion, a rising edge portion, and the like. FIG. 13 shows specific locations where rain leakage is likely to occur. Also, metal sheet roofing has the disadvantage that it absorbs solar heat in the summer and is thick inside the room, and in the winter it emits indoor temperature and is cold and has no heat insulation. The disadvantage is that the soundproofing effect is low.

Accordingly, an object of the present invention is to provide a waterproof function and a protection function.
It is an object of the present invention to provide a roofing material that simultaneously and integrally fulfills a makeup function. Further, another object of the present invention is to provide a roofing material for a tile rod that simultaneously and integrally satisfies a waterproof function, a protection / makeup function, and a heat insulation / soundproof function.

[0008]
