Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a synthetic resin floor tile used as a floor finishing material.

2. Description of the Related Art Conventionally, synthetic resin tiles represented by P tiles have often been used as floor finishing materials on the floor of offices.
These conventional tiles are adhesively fixed to a floor base with an adhesive before use. Most of these floor tiles have a thickness of 2.0 to 2.5 mm and a size of 30 cm square. On the other hand, in recent years, there has been an increase in the use of so-called floor tiles that do not require the use of an adhesive. Unlike the conventional tiles described above, this tile is basically as thick as 4 to 8 mm, and the size is about 50 cm (however, this is not a limitation of the present invention). By increasing the weight, suppress warpage and slippage,
It has a laying property. The number of such fixed tiles is increasing for the following reasons.

First of all, the above-mentioned conventional tiles adhere to the floor base with an adhesive, which makes it difficult to partially repair or replace them. Further, even in the case where the entire surface is replaced, a large amount of time and cost are required for the peeling work and the subsequent repair of the base. These problems are easily solved by using laid tiles.

Second, the increase in free access floors is remarkable with the spread of office equipment and office automation equipment. The free access floor is for accommodating the wiring of OA equipment and the like, and for facilitating the wiring change. A detailed description of this free access floor is omitted because it is not directly related to the present application, but a floor finish material is attached or placed (layed down) on the floor plate for use. However, this floorboard requires leveling, and conventionally, the floorboard was placed after adjusting the level with an adjusting screw attached to a column supporting the floorboard. However, recently, for ease of work, the floor plate is placed, and then the adjusting screw is turned through a hole provided in the floor plate to raise the level. If this method is used, it is not possible to attach the floor finish material to the floorboard in advance, and it is also required that the floor finish material can be easily attached and removed when changing the wiring. Therefore, a floor-laying type floor finish material is inevitably used. Has reached.

As mentioned above, the floor tiles are used in various places because they are easy to put on and take off, but the thickness is different from the pasting type tiles, so the first tile should be taken out when repairing or changing wiring. However, there is a problem that it is difficult to attach the tile to be inserted at the end. The reason is that the corner of the tile side edge collides with the side edge of another adjacent tile (see FIG. 3). In addition, dust is clogged between the tiles, and when the tile is taken out, the dust falls as it is and gets stuck on the base, that is, when the tile is reattached, the dust accumulated on the tile side edge raises the appearance and Not safe.

DISCLOSURE OF THE INVENTION Problem to be Solved by the Invention The present invention solves the above-mentioned drawbacks of conventional floor tiles, and provides a floor tile that can be easily attached and detached and that can prevent lifting of the joint portion due to dust accumulated on the joint portion. The purpose is to

The present invention is a soft or semi-rigid synthetic resin floor tile, in which at least two sides of the four sides of the tile are cut out at the corners on the back side over the entire length of the side to form a tapered surface. It is characterized by

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a side view showing an embodiment of the present invention, and FIG. 2 is a bottom view thereof. The tile 1 is made of a soft or semi-hard synthetic resin. Here, soft or semi-rigid refers to hardness that allows the tile to be easily bent during normal construction. The tile 1 has a two-layer structure including a front surface layer 2 and a back surface layer 3. The surface layer has a large amount of resin and is rich in stain resistance and abrasion resistance. The back surface layer has a large amount of filler, and thus has a large specific gravity and is excellent in laying property and dimensional stability. The thickness ratio between the front surface layer and the back surface layer is about 1: 5,
The total thickness is about 7 mm and the length of one side is about 50 cm. At least two sides of the four sides AB, BC, CD, DA of the tile 1 (corner AB, CD, in the drawing) on the back surface side, that is, the corners where the back surface 31 of the tile and the side surface 4 intersect. Cut out along the entire length of the side, from the back surface 31 to the side surface 4
The taper surface 5 is formed so as to face (and vice versa). The size of the tapered surface (notch degree) is not particularly limited, but if it is made too large, it may cause walking, movement of articles, etc.
Since the side edges may be recessed due to the load during use,
It is recommended that the side surface should be cut in half or less of the total thickness, and the back surface should be cut in the range of 5 mm or less from the edge toward the inside.

The tapered surface is provided on at least two sides of the four sides of the square tile. When it is provided on two sides, it is provided on two adjacent sides or two opposite sides. And in these cases, the effect of the tapered surface can be sufficiently exerted by paying a little attention during the construction. That is, if the two sides are opposed to each other, the lines are checkered, and if the two sides are adjacent to each other, the sides are not adjacent to each other. Of course, it may be provided on all three sides or all four sides. In the case of 3 sides, either a sink or a checkered floor may be used, and when a taper surface is provided on 4 sides, it can be laid randomly without paying attention to the direction.

Examples of the method of forming the taper include a method of cutting a corner with a blade such as a plane, a casting method, and a pressing method.

Effect of the Invention According to the present invention, when the first tile is lifted during partial repair or wiring change, the side edge of the lower surface is cut out and a tapered surface is formed so that it hits the side edge of another adjacent tile. It can be lifted smoothly without Also, when it is inserted in reverse, it can be easily replaced.
Furthermore, when the tile is returned to its original state, the space formed by the tapered surface and the ground becomes a dust accumulation, and the side edge of the tile does not float up due to the dust accumulated in the joint.
