Abstract

PURPOSE:To prevent deflection, pressure, and joint space from being generated, by setting a buffer body integrally on the side end section of floor tiles made of synthetic resin or rubber, and by absorbing the expansion and contraction of a heated floor which are generated due to the change of a temperature. CONSTITUTION:On the bottom surface 7 of a mold 3 consisting of the bottom surface 7 coinciding with the plane shape of floor tiles 1, and a separated section 5 having a tapered surface 4, the floor tiles 1 are mounted, and into the separated section 5 and a space 2', liquid-like substance 2 for a buffer body is injected and is solidified. The buffer body 2 is joined to a degree compressed slightly, and is arranged on a heated floor by using adhesives if required, and the floor is finished. Then, the expansion and contraction of the floor tiles 1 which are generated due to the change of a temperature are absorbed by the buffer body 2. Accordingly, warp projection and joint gap are prevented from being generated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a synthetic resin floor tile, particularly to a synthetic resin floor tile that can be laid on a heated floor.

[Prior Art] Recently, heating floors that heat indoor spaces from the floor have been increasing in Japan as well. As such a heating floor, one in which a pipe is embedded in a concrete slab and a heating medium is circulated through the pipe, or one in which a heater is embedded in a panel of a predetermined size is used. These heating floors cannot be used as they are, and floor finishing materials are laid on top of them. Carpet tiles and the like are used as these floor finishing materials, but carpet tiles have the drawbacks of being expensive, difficult to clean, and undesirable from a sanitary standpoint, such as the generation of dust mites. Therefore, from this point of view, it is desirable to use synthetic resin floor tiles.

However, when the heating floor is heated, the surface temperature is 60-70℃.
Temperature changes are extremely large, with temperatures reaching below 0°C in some places when no heat is being passed through. As a result, the synthetic resin floor tiles that are pasted on top of them are also affected by such temperature changes, and when heated, they expand, causing warping and upheavals, while at extreme temperatures, they contract, causing joint gaps. There was a problem and it needed to be solved.

[Objective] The object of the present invention is to provide a synthetic resin floor finishing material that does not warp, push up, or cause joint gaps even under wide temperature changes in heated floors.

[Structure] The floor finishing material for a heated floor of the present invention is characterized in that a buffer body is integrally provided at the side end of a floor tile made of synthetic resin or rubber. The floor covering material may be manufactured by any method, but advantageously, the method described above is used. That is, the floor tile is preferably placed face down on the bottom of a mold consisting of a bottom that matches the planar shape of the floor tile and a partition having a tapered surface that slopes upward from the edges of the bottom. The space formed by the side end surface of the tile and the tapered surface is filled with a liquid buffer composition, and the composition is cured and simultaneously integrated with the floor tile to produce a floor finishing material for heating floors. It is convenient to do so.

There are no particular restrictions on the dimensions of synthetic resin or rubber floor tiles, but they are usually 30 to 50 square inches in size and 2 to 7 meters thick, especially 4 to 6 meters thick. use. The material of the floor tile can be conventionally used synthetic resin-based materials or various rubber-based materials, but it is preferable to use a heat-resistant composition in view of the fact that it will undergo a lot of heat history. For this purpose, a stabilizer suitable for heat resistance may be added, or a relatively heat-resistant or heat-stable resin or rubber may be selected. In some cases, a filler with good heat dissipation properties, such as metal powder, may be added to prevent heat accumulation in the floor covering material.

The floor tile may have a single layer structure, but a layered structure may also be used. The surface layer should have a high resin content in consideration of abrasion resistance and stain resistance, and the lower layer should have a high specific gravity and a large amount of filler to improve placement.One surface layer should be approximately 0.
．． The thickness of the lower layer is preferably about 1.5 to 5 nm.

Any material capable of absorbing the expansion and contraction caused by temperature changes in the floor tile can be used as the buffer. Generally, an elastic body is preferred, and a foamed body having elasticity is most preferred, and one having a Shore hardness C of about 25 to 65 degrees is particularly preferred. If the cushioning material is not a foam, natural or synthetic rubber, which itself has cushioning properties, is used; however, in the case of a foam, rubber foam, polyurethane foam, polyvinyl chloride foam, Synthetic resin foams such as polyethylene foams can be used.

Of course, the structure of the shock absorbers may be such that adjacent shock absorbers come in contact with each other with smooth surfaces, but it is also possible to make the contact surfaces convex and concave to further prevent joint gaps in the floor finishing material. .

Further, it is preferable that the foam has a surface skin layer because the foam can be made more resistant to wear.

The width Q of the buffer body depends on various conditions, but it is usually sufficient if it is about 1 to 5 IIW11.

Of course, the floor finishing material of the present invention can be manufactured by applying an adhesive to the side surface of the floor tile and bonding the cushioning material, but it is also possible to manufacture the cushioning material and bonding it to the floor tile at the same time. is preferred.

To explain the present invention with reference to the drawings, FIG. 1 is a plan view of the floor finishing material of the present invention, and FIG. 2 is an example of a sectional view taken along line A-A' in FIG. The shape can take various shapes as shown in FIGS. 3-5.

Figures 3-5 are models illustrating the method for manufacturing the floor covering of the present invention.

The floor tile 1 is placed on the bottom surface 7 of a mold 3 consisting of a bottom surface 7 that matches the planar shape of the floor tile 1, and a partition portion 5 and/or a step portion 6 having a tapered surface 4 that slopes upward from the side edge of the bottom surface 7.
is preferably placed with its surface facing down, and a liquid buffer composition is placed in the space 2' formed by the side surface of the floor tile 1 and the partition section 5 and/or step section 6 having the tapered surface 4. The floor finishing material of the present invention can be applied by solidifying the composition (including foaming and solidifying) and simultaneously integrating it with the floor tile.

If the buffer is a foam, any foamable or foam-containing composition can be used as the composition.

If the mold is provided with a partition or a step, positioning of the floor tiles when placing them in the mold is easy, and manufacturing efficiency can be significantly improved.

In addition, when used as a floor finishing material, the cushioning body has the taper or step difference, so even when the floor tile expands greatly, the cushioning body has the effect that there is room for deformation and it does not protrude from the spherical surface. .

[Eco-application of the floor finishing material of the present invention] The cushioning body of the floor finishing material is joined to the extent that it is slightly compressed, and if necessary, it is lined up on the heated floor using an adhesive to finish the floor.

[Effects] By using the floor finishing material of the present invention, the synthetic resin tile finished surface formed on the heated floor will not warp, push up, or have joint gaps.
