Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit roof material for roofing a roof and a roof plate structure thereof.

[0002]

2. Description of the Related Art Conventionally, a roofing material for roofing is made of a simple plate material, and a required number of sheets and a required portion thereof are stacked to form a roofing sheet (roofing). That is, the degree of overlap depends on the intuition of the builder, and requires skill to carry out the work without rain leakage.

SUMMARY OF THE INVENTION In view of such circumstances, it is an object of the present invention to provide a unitized roofing material having a simple structure and capable of uniform construction.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a rectangular plate-like projection is formed on one surface of a rectangular plate, and both side edges of the projection have the rectangular shape. They are on the same length inside from the side edges of the plate, and one long side of the protrusion matches one long side of the rectangular plate, and the short side of the protrusion is three minutes of the short side of the rectangular plate. That is, the roofing material has a length of 2.

Further, as an invention using the roofing material having this structure, the roofing materials are arranged vertically and horizontally with the projecting portion of the roofing material on the lower side, and the downward vertical direction is the one long side of the roofing material. It is on the lower side, and it is on the same axis with one-third overlapping on the upper surface of the lower roof material. On the other hand, in the lateral direction, one of the adjacent roof materials is the other, the third of its short side. Of the roof plate which is vertically offset by 1 and is inserted between the side portions of the adjacent upper and lower roof members and is in contact with the protruding side edge of the roof member ( That is the structure.

The roofing material may be any weather-proof fiber reinforced plastic plate (FRP plate), metal plate, ceramic plate, or synthetic plate thereof, as long as it conforms to the building standard. The protrusion may be integrally formed with the rectangular plate by resin molding or the like.

[0007]

In the construction of the roofing material thus constructed, the long side or the short side of the projection is used as a reference for stacking or inserting. That is, in the stacking in the vertical direction, the work is performed so that the long side of the rectangular roof plate of the upper roof material coincides with the long side of the lower roof material. On the other hand, in the horizontal insertion, while inserting the rectangular plate side portion of the adjacent roof material into the side gap of the upper and lower roof material rectangular plates caused by the presence of the protrusion,
Construction is performed so that the upper long sides of the adjacent roofing material rectangular plates coincide with the upper long sides of the roof plate projections in which the side gaps are formed.

In the construction state, the upper roof material overlaps the lower roof material in the vertical direction, so that rainwater flows smoothly downward. In addition, since the rectangular plate abuts the protrusion in the lateral roof material overlapping portion, a waterproof effect can be obtained by the abutting, and the water leakage prevention by stacking is further improved.

[0009]

EXAMPLE As shown in FIG. 5A, the long side: 450 mm,
Short side: 240 mm on one side of the rectangular plate 1a, which is also rectangular,
A roofing material 1 having a protrusion 1b having a long side of 370 mm and a short side of 160 mm is manufactured by FRP integral molding.

Both side edges of the projection 1b are located 40 mm inside from the side edges of the rectangular plate 1b, and one long side of the projection 1b coincides with one long side of the rectangular plate 1a.
The protrusion 1b has a thickness of 10 mm, and the rectangular plate 1a has a thickness of 9 mm. Due to this difference of 1 mm, the other roof material 1 of the roof material 1 described later and the space t between the side parts (see FIG. 3) The insertion can be done smoothly.

Auxiliary roofing material 2 for the eaves and the bare wood portion
As shown in Fig. 2 (b), made of FRP, long side: 450 m
A plate-like body with m, short side: 160 mm, and thickness: 9 mm is manufactured.

To roof the roof R shown in FIG. 1 with the roof materials 1 and 2, the following procedure is performed, which will be described with reference to FIGS. 2 to 4. It should be noted that FIGS. 3 and 4 are from below, and the dash (1 ′, 1a ′, 1b ′) is attached to one roof material 1 that is adjacent in the lateral direction.

First, as shown in FIGS. 2 and 3, in the vertical direction, the lower long side of the upper roofing material 1 is aligned with the upper long side of the protrusion 1b of the lower roofing material 1. Overlap one-third for construction. On the other hand, in the lateral direction, the side gap t between the upper and lower rectangular plates 1a of the roof material caused by the presence of the protrusion 1b.
The rectangular plate 1a side part of the adjacent roofing material 1 is inserted into, and the upper long side of the adjacent roof plate rectangular plate 1a is matched with the upper long side of the roof plate 1 protrusion 1b forming the side gap t. Install as you would.

Further, the eaves or the bare wood portion is an auxiliary roof material 2
Insert and stack in the same manner.

The roof plate R thus constructed is constructed from the lower side (eave side), and the roofing materials 1 and 2 are fixed to the field material 3, the dead wood or the like at appropriate points with nails c, screws or the like. A waterproof seal or an adhesive may be interposed between the overlapping portions.

It is preferable that a plurality of such roofing materials 1, for example, one vertical row be integrated in advance in a factory or the like, and that they be transported to the site for construction, and the number of one unit is easy to carry and work. Take into consideration and select appropriately. As shown in FIGS. 3 and 4, the unitization is performed by striking (screwing) the nail c or the screw so as not to penetrate the overlapping portion.

In the construction state shown in FIG. 1, in the vertical direction,
Since the roof material 1 on the upper side overlaps with the roof material 1 on the lower side, rainwater flows smoothly downward. Further, in the lateral roofing material 1 overlapping portion (see FIG. 4), since the rectangular plate 1a abuts on the protruding portion 1b, a waterproof effect can be obtained by the abutting, and water leakage prevention by stacking is further improved. I am letting you.

Needless to say, the respective dimensions of the roofing material 1 are not limited to those in the embodiment, and may be appropriately determined in consideration of manufacturability, transportability and the like.

[0019]

Since the present invention is constructed as described above and has a simple structure and is capable of performing uniform construction, it is possible to carry out roofing at a low cost.

In addition, in stacking roofing materials, it is safe to check the long and short sides of the rectangular projection at the required position (one-third cutout, etc.) of the required size relative to the rectangular plate. Since it can be installed, there is also an advantage that no skill is required for the installation.
