Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to roof tiles, and particularly to a laminated roof tile comprising multiple layers of different materials.

[Prior Art] Clay, cement, etc. are widely used as materials for tiles, and these clay tiles and cement tiles are made of the single material mentioned above.

In addition, some asbestos slate roof tiles are known to have multiple layers, but this is simply a thin layer of acrylic silicone paint applied to the surface of the asbestos slate base material for coloring. is substantially made of a single material.

[Problems to be Solved by the Invention] However, these roof tiles each have a unique level of properties such as strength, weight, drainage, and heat insulation properties based on their materials.
There are limits to how much this can be changed.

For example, clay tiles and cement tiles must be heavy in order to obtain the necessary strength. This was a major obstacle to speeding up the process.

The present invention has been made in view of these problems, and has achieved a balance between the above-mentioned properties, in particular, enables significant weight reduction while maintaining sufficient strength, and also satisfies the requirements for water drainage, insulation, etc. The purpose is to provide a laminated tile that can be obtained.

[Means for Solving the Problems] In accordance with the above-mentioned objective, Kokuhatsu 1lJ1 proposes a roof tile consisting of multiple layers of different materials, that is, the present invention has a metal mesh body integrally incorporated in a biting shape. A laminated tile (Claim 1) characterized in that it comprises a core material layer, and a waterproof finishing material layer adhered to the surface side of the core material layer (Claim 1); The present invention relates to a laminated tile according to Claim 1 (Claim 2) which is formed by bonding foam material layers, and each of these is the gist of the present invention.

Here, the metal mesh is 1, for example, stainless steel wire mesh, general wire mesh (round, diamond, Kusombu, Kuko, welded wire mesh, etc.), lath (wire or metal lath, lath sheet, etc.)
1 expanded metal, woven wire mesh, non-ferrous wire mesh, etc. may be used. Of course, these wire diameters, plate thicknesses, details, etc. are selected depending on design conditions such as strength.

The core material layer mainly ensures structural strength together with the metal net, and may be made of, for example, Valve Cement 15 asbestos cement, reinforced plastic, especially FRP, or other materials.

In addition, materials such as synthetic rubber, vinyl chloride, asphalt, etc. can be used for the finishing layer. Specific examples include vulcanized or non-vulcanized rubber, vinyl chloride resin, and ethylene resin. Polymer roofing, asphalt felt, asphalt roofing and other materials can be bonded by pasting, painting or spraying.

Furthermore, the foam material layer is made of 1-foam urethane resin, which has high elasticity and water resistance, and it is convenient and excellent for manufacturing to spray it and attach it to J1i. In addition, thermosetting resins such as urea foam and phenol foam can also be used; the former has advantages in moldability to a uniform thickness, and the latter has advantages in flame retardancy. In addition.

Since expanded styrene resin and PVC foam are relatively heat-resistant, they should be used when the temperature rise of the foamed material layer is suppressed to within the safe operating temperature by the above-mentioned core material or the like.

Of course, the thickness and material of each of these layers are determined depending on the above-mentioned required level of strength, water resistance, heat insulation, etc., cost, ease of manufacture, and other design conditions.

[Function] With the above configuration, the core material layer containing the metal mesh mainly contributes to maintaining strength, the finishing material layer mainly contributes to drainage, and the foam material layer mainly contributes to heat insulation.

[Example] Each figure shows a different example, and first, Fig. 1 shows a cross-sectional view of a laminated tile of the present invention with a part thereof cut away.
The laminated tile 1 has a waterproof finishing material layer 4 adhered to the surface side of a core material layer 3 in which a metal mesh body 2 is integrally incorporated in a recessed manner, and a waterproof finishing material layer 4 is adhered to the back surface side of the core material layer 3. is formed by adhering the foam material layer 5.

In this example, these materials include stainless steel wire mesh for the metal mesh body 2, pulp cement for the core material layer 3, and pulp cement for the core material layer 3.
The finishing material layer 4 is made of synthetic rubber, and the foaming material layer 5 is made of sprayed foamed urethane resin. The thickness of each layer is 1, for example, the core layer 3 is 3 mm to 6 mm and 8 degrees, the finishing layer 4 is about 2 mm to 3 mm, and the foam layer 5 is about 5 mm to 10 mm.

Next, Fig. 2 and subsequent figures show examples of various types of roof tiles. First, Fig. 2 shows an example in which the present laminated tile 1 is adopted as a flat tile among Japanese tiles, and as shown in the figure, a metal mesh 2. Core material layer 3. Finishing material layer 4,
A foam material layer 5 is also provided. Further, in this example, the core material layer 3 and the finishing material layer 4 are formed into a dovetail shape at the edge portion 6 of the tile 1, and the end portions are treated.

Further, FIG. 3 shows a case in which it is adopted as a round tile among Japanese tiles, and is equipped with a metal mesh body 2, a core material layer 3, and a finishing material layer 4. In addition, in this example, the finishing material layer 4 is bonded so as to wrap around not only the front side of the core material layer 3 but also the back side thereof. Also, the foam material layer is omitted.

On the other hand, Figures 4 and 5 show examples in which this laminated tile l is used as an Okinawan tile. In the example in Figure 4, the metal net 2, core layer 3, finishing layer 4, and foam material! a5, of which the foam material layer is omitted in the example shown in FIG.

Although not shown in the drawings, this laminated tile can of course be used for other forms of ridge tiles (for example, keraba tiles, ridge tiles, ridge retainers, ridge tiles, eaves tiles, etc.).

Although the embodiments have been constructed as described above, the present invention is not limited to the specific shapes, structures, dimensions, materials, and numbers of the metal mesh, core material layer, finishing material layer, foam material layer, etc., as long as it does not contradict the gist of the invention. It goes without saying that the relationship between these and the form of the tiles can be changed in various ways and are not limited to the above embodiments.

[Effects of the Invention] Since the laminated tile of the present invention is constructed according to the above-mentioned gist, the core material layer containing the metal net body mainly provides strong fibers and is lightweight, while the finishing material layer This ensures water drainage, and if a foam layer is provided, the insulation can be further improved.

In this way, the laminated tile of the present invention allows each layer made of different materials to share a superior function, thereby achieving a perfect balance between strength, weight, water drainage, insulation, etc. as a whole. As a result, in particular, while maintaining sufficient strength and meeting the requirements such as drainage and insulation,
It is possible to achieve significant weight reduction.
