DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor material used for repairing, for example, a conventional tatami floor to a flooring floor or the like and a method of constructing the floor material.

[0002]

2. Description of the Related Art Conventionally, as a method of repairing a conventional tatami floor to a flooring floor or the like, a simple method of removing an existing tatami floor and directly installing flooring such as flooring or carpet on a slab, In some cases, all of the flooring material, including slabs and joists, is removed and rebuilt from the flooring material.

[0003]

As described above, in the case of the conventional flooring material and its construction method, the former can shorten the construction period and can perform repair work at low cost. Because the difference in thickness between the tatami mat and the newly installed floor material, and a step between the sill (tatami mat) and the floor surface,
When entering and exiting the room, there was a problem that the threshold was obstructed and the livability deteriorated. In addition, flooring and carpet have poor sound insulation performance (sound insulation performance) as compared with conventional tatami mats, so that there is a possibility that a new noise problem may occur on downstairs.

On the other hand, in the case of the latter, the floor surface is adjusted to the height of the sill in order to redo the entire floor, and a material having high sound insulation performance is used for the floor material, and a rubber cushion or the like is provided between the floor material and the joist. Although the above-described inconvenience does not occur by interposing, the construction period becomes longer and the cost increases. In particular, in a house with a resident, if the construction period is long, the resident is forced to have an inconvenient life.

According to the present invention, it is possible to provide a sound insulation performance equal to or higher than that of a conventional tatami floor without deteriorating a walking feeling and a level difference from a sill, and to easily perform construction in a short period of time. It is an object of the present invention to provide a floor material and a method of constructing the floor material.

[0006]

The flooring material of the present invention is a flooring material to be laid on a slab, in which, in order from the bottom, a foamed plastic base material, a support material and a sound-insulating floor finish material are laminated. It is characterized in that it is configured to be approximately the thickness of a tatami mat.

[0007] According to this configuration, the impact sound (light floor impact sound and heavy floor impact sound) generated on the upper surface of the floor finishing material, that is, the floor surface, is mainly generated by the foamed plastic base material and the sound insulating floor finishing material. Since it is attenuated, it has a sound insulation performance equal to or higher than that of a conventional tatami (straw tatami) having an air layer and being heavy. In addition, by using foamed plastic base material, it is higher than conventional tatami mats (1.5 times)
Heat retention performance can be obtained. Further, even if a plastic base material having flexibility is laminated due to the rigidity of the support material, extreme sinking of the floor is prevented, and walking feeling is not impaired. Furthermore, since the flooring material itself is laid on the slab, construction can be performed easily and in a short period of time. In addition, since the whole is configured to have a thickness of approximately tatami, no step is formed between the tatami mat and the existing Japanese-style room even if the tatami mat is constructed. In addition, these floor components may be configured integrally by bonding or the like, or may be configured separately.

In this case, the foamed plastic base material is
It is preferable that the lower high foamed plastic base material and the upper low foamed plastic base material are stacked and laminated.

[0009] According to this structure, the heavy floor impact sound can be mainly attenuated by the high foamed plastic base material, and the lightweight floor impact sound can be mainly attenuated by the low foamed plastic base material. Therefore, sound insulation performance can be improved as a whole. In order to further enhance the sound insulation performance, it is preferable that the high foamed plastic base material is thicker than the low foamed plastic base material in order to concentrate the light floor impact sound.

In these cases, it is preferable that a hook-and-loop fastener is interposed between the support member and the sound-insulating floor finishing material.

According to this configuration, even if the support material and the sound-insulating floor finishing material are formed separately, the support material after the construction and the vibration-proofing mat are integrated, so that the sound-insulating floor finishing material is used. Can be prevented from partially floating. When the sound-insulating floor finishing material is formed in a panel shape,
Since the positional displacement of the sound-insulating floor finishing material at the time of laying is prevented, construction and replacement can be performed easily and quickly.

In the first or second aspect, it is preferable that the sound-insulating floor finishing material is formed by laminating a lower sound insulating material and an upper finishing material.

According to this configuration, even when the same finishing material is used, the sound insulating performance can be adjusted for each construction site by selecting the sound insulating material. Further, the floor pattern can be changed simply and at low cost only by changing the finishing material.

In this case, it is preferable that a hook-and-loop fastener is interposed between the supporting material and the sound insulating material and between the sound insulating material and the finishing material.

According to this configuration, it is possible to prevent the floor finishing material from partially floating. Further, when the floor finishing material is formed in a panel shape, misalignment of the floor finishing material at the time of laying is prevented, so that the construction can be performed easily and quickly. Further, the replacement of the finishing material is facilitated, and the sound insulating material and the finishing material can be removed, and this part can be replaced with an alternative sound insulating finishing material.

The method for constructing a flooring material according to the present invention is a method for constructing a flooring material having a laminated structure having a thickness of substantially all tatami mats, wherein a panel-like plastic substrate is laid on a slab. A material laying process, a support material laying process of laying a panel-shaped support material having a size different from that of the plastic base material on the plastic base material, and a panel shape of a size different from the support material on the support material And a step of laying the sound-insulating floor finishing material.

According to this configuration, since the constituent members of the flooring material are different in size, the joints do not overlap each other in the process of laying down these members in order. For this reason, even if these constituent members are formed in a size (panel shape) that is easy to carry or carry in, and they are laid, they will not impair the sound insulation performance and walking sensation. Also,
With this laminated structure, sound insulation performance can be made equal to or more than that of a tatami mat, and construction can be performed easily and in a short period of time. In addition, since construction can be performed without using nails or the like, noise during construction can be reduced.

[0018] Further, another construction method of a floor material according to the present invention is a construction method of a floor material having a laminated structure having a thickness of substantially tatami, wherein a panel-like plastic base material is placed on a rough plate. A base material laying process of laying down the material, a support material laying process of laying a panel-like support material having a size different from that of the plastic base material on the plastic base material, and a size different from the support material on the support material A sound insulating material laying step of laying a panel-like sound insulating material, and a finishing material laying step of laying a floor finishing material on the sound insulating material.

According to this configuration, since the constituent members of the flooring material are different in size, the joints do not overlap with each other in the process of laying them in order. For this reason, these components are formed in a size that is easy to carry or carry in,
Even if this is laid, the sound insulation performance and walking feeling are not impaired. Further, the floor pattern can be easily changed simply by changing the finishing material.
