Description

  The present invention relates to a composite flooring. More specifically, the present invention relates to a composite floor material obtained by laminating a floor finishing material on a base material and a joining structure thereof.

  Conventionally, as a flooring material, for example, a wooden flooring material in which a plywood is used as a base material and a veneer is laminated on the surface is generally used as a so-called flooring material. The above-mentioned flooring material is widely used in living rooms and the like with the westernization of lifestyles, and is usually applied to floor bases using fixing means such as adhesives, nails, screws, and other construction members. Yes.

  On the other hand, it does not damage the ground floor on the rooftop of buildings such as houses, verandas, balconies, etc., and it can be laid with high accuracy, and the flooring can be easily replaced, and there is no peeling due to strong winds. A permeable floor material for roof balconies and a laying structure thereof have been proposed that are unlikely to cause steps or rattling on the walking surface.

  In Patent Document 1 below, in a permeable floor material for a roof balcony formed by bonding a porous ceramic plate to a semi-rigid resin base material, a semi-rigid resin base material is provided on one side of the small edge surface of the permeable floor material. The roof is characterized in that a porous ceramic plate is protruded from the small edge surface, retracted on the opposite side, and a notch is provided on the upper edge portion of the semi-rigid resin base material on the back side of the protruding portion. A water-permeable floor material for a balcony and its laying structure are disclosed.

And while permeable flooring for roof balconies can be placed with high precision without damaging the groundwork, it is easy to replace damaged flooring and improve workability and walkability. The effect that the floor material can be prevented from curling and lifting due to the negative pressure on the floor surface is described.

  By the way, the depletion of timber resources and the worldwide movement to protect resources have made it difficult to obtain Muku timber, and the price of plywood substrates produced from materials made by peeling Muku timber is also rising. In view of this, waste wood and sawdust from lumber mills and wood scraps from the construction process are crushed to obtain wood fibers, heated in the presence of adhesives, processed into wood fiber boards, and then used as a base material for construction It is also being used as.

  On the other hand, the method of placing and directly pasting the floor material directly on the floor base is being adopted not only for roof balconies described in Patent Document 1 but also for flooring of ordinary houses in recent years. Construction methods using the wood-based material made as a base material have been developed.
