Description

[Detailed Description of the Invention] The present invention relates to an improvement of a floor panel for a floating floor using a particle board made by compressing wood chips together with a synthetic resin and molding it into a plate shape.

Particle board is susceptible to dimensional changes due to humidity or dryness, so when used as a floor panel for a floating floor that requires high dimensional accuracy, it is necessary to devise measures to prevent it from being affected by humidity or dryness. Normally, a moisture-proof synthetic resin board that also improves strength is bonded to the front and back sides, which occupy most of the total surface area.
Even if the peripheral side is moisture-proofed to some extent, if an engagement hole is drilled on the back side of the panel into which the engagement protrusion of the support leg is inserted, the influence of moisture and dryness from this engagement hole will be surprisingly large. There are things that cannot be ignored.

Therefore, the present invention has been developed by inserting a cap with a flange made of rubber or soft synthetic resin into the engagement hole into which the engagement protrusion of the support leg is inserted. In addition to being able to prevent this, it also buffers the contact between the panel and the support legs when the panel is laid as a bridge on the support legs, and also provides a low-cost floor panel for floating floors that does not easily fall off due to vibrations such as earthquakes. It is intended to be provided to

Hereinafter, an example of the implementation of the present invention will be explained based on the drawings.The panel 1 is made by compressing wood chips together with synthetic resin and molding it into a plate shape, and moisture-proof synthetic resin plates 2 are attached on the front and back sides as in conventional products. They are glued together and a carpet material 3 is further pasted on the front side. A moisture-proof tape 4 is adhered to the circumferential side of the panel body 1, and an engaging hole 7 into which the engaging protrusion 6 of the support leg 5 is inserted is bored on the back side. Insert cap 8.

The cap 8 is made of rubber or a soft synthetic resin material with flexible elasticity and is molded to tightly fit into the engagement hole 7, and further covers the mouth edge of the engagement hole 7 and extends to the back side of the panel body 1. It is made by integrally forming the tsuba described above.

The moisture-proof tape 4 is made of a synthetic resin film such as polyethylene or polypropylene, metal foil such as aluminum, or moisture-proof paper such as kraft paper, and is adhered to the peripheral side of the panel body 1. . The moisture-proof tape 4 may be coated with adhesive in advance, but in the case of films made of synthetic resins such as polyethylene or polypropylene, the panel body can be bonded by heating with a hot trowel without having to coat the adhesive. Can be attached to the peripheral side. In addition, this moisture-proof tape 4 covers the peripheral side of the panel body to improve the appearance and increase the product value.
It is desirable to color the material so that it is opaque and has a metallic luster.

Then, the cap 8 is fitted into the engagement hole 7 on the back side of the panel main body 1, and the panel is placed across the support legs 5 arranged at equal intervals vertically and horizontally, and the cap 8 is The explanation will be made by fitting the engagement protrusion 6 of the support leg 5 into the fitted engagement hole 7.

In this way, the present invention creates engagement holes for drying the engagement protrusions of the support legs on the back side of the panel body, which is formed by compressing wood chips together with synthetic resin into a plate shape, and fills the engagement holes with rubber. Alternatively, a cap having a crocodile molded from a soft synthetic resin material is fitted into the cap, so that it is possible to eliminate the influence of moisture and dryness from the engagement hole of the panel body, and also to buffer the contact between the panel and the supporting legs.
In addition, it becomes possible to prevent it from falling off due to vibrations such as earthquakes. That is, during manufacturing or on-site processing, the effects of moisture and dryness from the engagement hole can be eliminated by simply inserting the cap into the engagement hole, which can be provided easily and at low cost.

The cap's brim cushions the contact between the panel and the support legs when the panel is laid on the support legs, improving walkability and livability.
Moreover, since it also serves as a non-slip member, there is no risk that the floor panel will easily fall off the support legs due to vibrations such as an earthquake.

Therefore, the intended purpose can be achieved.
