Description

  The present invention relates to a floor covering material used by laying on a floor such as a veranda, a balcony, or a rooftop.

  Conventionally, the technology for laying floor materials on verandas, balconies, rooftops, etc. to form decks is to fix a plurality of fixed substrates with locking grooves on joists and cut them according to the dimensions of the balcony. A structure has been proposed in which the protrusion on the back side of the long deck material is press-fitted into the locking groove of the fixed substrate.

  On the other hand, in recent years, as described in Patent Document 1, for example, a hard synthetic resin is molded into a rectangular shape as a flooring material configured to lay a flooring material on a concrete slab and cover the floor surface. There is a floor material in which a plurality of legs are integrally formed to form a drainage space between the back side and the slab surface, and a surface material such as resin or tile is locked and fixed or integrated on the upper surface A unit-type floor decorative material having a molded structure has also been put into practical use.

When such a unit-type floor decorative material is laid outside such as a balcony or a veranda, if the wind blows into the lower surface side of the floor decorative material, the entire floor decorative material may swell. Thus, in order to eliminate such rolling-up, for example, as described in Patent Document 2, when a floor surface is formed by laying a tile unit, water permeability is applied to at least a part of the periphery of the floor surface. A tile unit laying structure in which a resin floor mat having an opening is laid to reduce the influence of wind has also been proposed.
