Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile to be roofed on a roof of a house or the like, and more particularly to a tile having a structure for stabilizing a stacked state when a large number of tiles are stacked.

[0002]

2. Description of the Related Art Conventionally, tiles of various shapes have been manufactured by molding a composition obtained by mixing cement, aggregate, synthetic fiber or asbestos and water with a forming method such as papermaking, dewatering press or extrusion. Have been. The manufactured tiles are stored or transported in a state where a plurality of tiles are stacked and packed, and placed on roofing material on the roof base surface in a state where four to five tiles unpacked at the construction site are stacked. I took it out one by one and laid it.

[0003] For example, in the case of tiles having different thicknesses of the tile body depending on the location, when storing or transporting the tiles, if a large number of tiles are stacked, the stacked tiles become inclined and unstable. There is a risk that a troublesome work of stacking a large number of broken roof tiles again due to crushing during transport and complicating the work is required. In the worst case, there is a risk that the roof tiles may be damaged.

Therefore, as described in Japanese Patent Application Laid-Open No. 4-350241, a projection is provided on the back surface of a tile body, and the projection is brought into contact with the surface of a lower tile to make the upper and lower tiles parallel. By holding the tiles vertically stacked so that their edges are aligned vertically with respect to the mounting surface, it is possible to prevent load collapse during transportation However, in the case of tiles that have been painted and painted with glaze applied to the surface of the tiles, when a large number of tiles are stacked and placed on a steeply inclined roof foundation, Tiles stacked along the slope of the roof ground surface could be rubbed and slipped down by the vibration of walking. For this purpose, a wooden bar was provided horizontally on the roof base to prevent the tiles from sliding down.

[0005]

However, according to the construction method in which a wooden bar is provided horizontally on a roof base surface and a large number of tiles are temporarily placed in a state of being stacked thereon, the slip prevention can be eliminated. However, it is troublesome to fix the wooden bar by nailing it to the base of the roof before installing the tile, or to remove the wooden bar after installing the tile, and to remove the nail hole after removing the wooden bar. It was necessary to cover the device with a silicon sealer.

The present invention has been made in view of such circumstances, and when a plurality of tiles are temporarily stacked on a roof base surface in a vertically stacked state to perform the tile laying work, the tiles slide on the roof base surface. It is intended to provide a roof tile capable of preventing the occurrence of the roof tile.

[0007]

In order to achieve the above object, a tile according to the present invention is a tile having a support portion formed on the back surface of the tile, and at least the support portion on the back surface of the tile. Is covered with a plastic foam layer.

In the present invention, the plastic foam layer is not particularly limited, and examples thereof include foamed polyethylene, foamed polyurethane, foamed neoprene rubber, and the like having a slip preventing function.

In order to cover the support portion on the back surface of the tile with a plastic foam layer, besides a method of applying a foamable resin to the support portion and foaming, a conventionally known foam plastic tape base is used. There is a method in which an adhesive tape having an adhesive layer provided on one side of a material is attached to a support.

As the base material of the pressure-sensitive adhesive tape, a tape-shaped material having a slip-preventing function of foamed plastic such as foamed polyethylene or polyurethane or foamed rubber such as neoprene rubber can be used. An adhesive or a rubber-based adhesive such as butyl rubber can be used.

In the present invention, the support portion on the back surface of the tile is not particularly limited, and includes, for example, a protrusion protruding in the middle between the edges of the back surface of the tile body. When a plurality of tiles are stacked one on top of the other, these projections are supported by the projections so that the upper and lower tiles are spaced at a fixed interval, and their edges are substantially aligned with the mounting surface on a vertical plane. preferable.

[0012]

In the roof tile according to the present invention, since the support portion is covered with the plastic foam layer, the support portion is protected by the plastic foam layer. Work on the roof even if it is temporarily placed on the roof base of a sloping roof with multiple tiles stacked vertically, supported on the lower tile surface or the roof base through the plastic foam layer Tiles do not slip and fall inside.

[0013]

Next, embodiments of the present invention will be described in detail with reference to the drawings. 1 is a rear view of a tile according to the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, FIG. 3 is a sectional view taken along line BB of FIG. 1, and FIG. FIG. 5 is a cross-sectional view showing a use mode of the tile of the present invention shown in FIGS.
