3. Since the mounting work to the plate-like floor covering 10 and other floor covering height adjusting units 1 is simple, the work load is small.

  In Example 1, the floor covering material height adjusting unit 1 of the present embodiment was mounted on an existing plate-like floor covering 10 and a load resistance test was performed. As the plate-like floor covering 10, a trunk checker for a trunk room manufactured by Mizushima Kogyo Co., Ltd. was used. The plate-like floor covering material 10 is made of recycled polypropylene, and is formed in a square shape having a length and width of about 300 mm and a height of about 25 mm. In addition, a total of 100 cylindrical leg portions 102 are arranged at equal intervals on the back surface, 10 pieces in the vertical direction and 10 pieces in the horizontal direction.

  The floor covering material height adjusting unit 1 according to the first embodiment is made of recycled polypropylene as in the case of the plate-like floor covering material 10, and the height of the columnar leg 2 excluding the protrusions 4 is about 25 mm. . In this load-bearing test, this columnar leg 2 was attached to the cylindrical leg portion 102 of the plate-like floor covering 10 every five pieces in the vertical direction and five in the horizontal direction, for a total of 25 pieces. The height of the plate-like floor covering material 10 to which the floor covering height adjusting unit 1 was attached was 50.2 mm.

As shown in Table 1 below, a weight of 102.5 kg to 994.5 kg is placed on the plate-like floor covering 10 equipped with the floor covering height adjusting unit 1 and the floor covering height is measured.

Furthermore, when a 402.5 kg weight was placed, it shrank by 1.2 mm and the height was 49 mm.

  On the other hand, when a weight of 402.5 kg or more was placed, there was no change in the amount of change when a weight of 402.5 kg was placed. Therefore, the plate-like floor covering 10 equipped with the floor covering height adjusting unit 1 in this load bearing test has a limit value for the amount of shrinkage.

  In addition, after the load resistance test, although slight distortion could be visually confirmed on the bottom surface of the cylindrical leg portion 102 of the plate-like floor covering 10, the plate-like floor covering 10 was not damaged greatly. In addition, no distortion or breakage was observed on the floor covering height adjusting unit 1 side.

  As described above, the floor covering material height adjustment unit 1 and the floor covering material material 10 to which the floor covering material height adjustment unit 1 is attached in the first embodiment are slightly shrunk or distorted by the load. Etc. were on the plate-like floor covering 10 side. Further, it was found that the plate-like floor covering 10 is not damaged even when a load of about 1 ton is applied. Further, the columnar legs 2 in the load bearing test support every other cylindrical leg 102, but it was found that no distortion or breakage occurs even in this state. Therefore, it was found that the floor covering height adjusting unit 1 in Example 1 has sufficient strength to support the plate-like floor covering 10 in practical use.

  In addition, the floor covering material height adjusting unit 1 according to the present invention is not limited to the above-described embodiment, and can be appropriately changed.

  For example, the installation location of the plate-like floor covering material 10 is not limited to a trunk room, and may be, for example, a rooftop of a building or a floor surface of a veranda.

  Further, the plate-like floor covering 10 supported by the floor covering height adjusting unit 1 is not limited to a slat-like thing having air permeability, but includes various kinds such as a plate-like floor covering 10 for OA floor. The plate-like floor covering material 10 may be sufficient.
