Description

  The present invention relates to a floor panel that is disposed, for example, under a washing machine or a dishwasher and can effectively suppress vibration thereof.

  In industrialized houses, floor panels manufactured in advance at a factory are used as flooring materials. The floor panel has, for example, a substantially rectangular shape in plan view with a standardized dimension, and is laid down on a horizontal material such as a large pull to constitute a continuous floor. A general floor panel includes a plurality of joists arranged in parallel and a plate-like floor base material disposed thereon (see, for example, Patent Document 1 below).

  However, the floor panel as described above cannot sufficiently absorb vibrations of a vibrator placed thereon, such as a washing machine or a dishwasher. For this reason, the vibration of the washing machine arranged in the washroom may propagate to the living room or the first-floor bedroom through the floor panel. In particular, in recent years, since washing machines, dishwashers, and the like are sometimes operated using inexpensive late-night power, it is strongly desired that the floor panel itself has a performance of absorbing sufficient vibration. .

  The present invention has been devised in view of the above problems, and has as its main object to provide a floor panel having excellent vibration absorption performance.

  The present invention is a floor panel used for constituting a floor of a building, and includes a floor structure material and a floor finishing base material arranged on the upper side of the floor structure material, At least a part thereof includes a movable part supported on the floor structure material so as to be movable in the vertical direction and the horizontal direction via a vibration absorber.

  In the floor panel of the present invention, the floor finishing base material includes a fixed portion fixed to the floor structure material so as to be immovable, and the fixed portion is provided around the movable portion with a gap therebetween. It is desirable.

  In the floor panel of the present invention, the vibration absorber includes a first absorber and a second absorber, and the first absorber has the movable portion in a first vertical load range that acts on the movable portion. Preferably, the second absorbent body supports the movable part together with the first absorbent body when the second absorbent body is in a second vertical load range that is larger than the first vertical load range.

  In the floor panel of the present invention, in a state where a vertical load is not applied to the movable part, the upper surface of the second absorbent body is separated from the movable part and positioned below the upper surface of the first absorbent body. It is desirable.

  In the floor panel of the present invention, the first absorbent body is provided on the outer peripheral side of the movable part, and the second absorbent body is provided on the inner peripheral side of the movable part with respect to the first absorbent body.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a partial perspective view of a floor F of a building. The floor F is formed of, for example, a plurality of floor panels 1, 101, 102. Each of the floor panels 1, 101, 102,... Constitutes a continuous floor surface, for example, by being arranged on a horizontal material such as a large pull a. The floor panel 1 of this embodiment is suitably used as a floor of a house, for example, and can be suitably implemented as a floor panel for placing a vibrating body b such as a washing machine or a dishwasher. The other floor panels 101 and 102 are existing floor panels and have the same configuration as the conventional one.

  The floor panel 1 of the present embodiment is, for example, a substantially rectangular panel body in plan view, and is preferably made in advance at a factory or the like. The floor panel 1 is preferably dimensioned so that it can be used in combination with other existing floor panels 101, 102, for example. Although the floor panel 1 of this embodiment is made into square shape, it is not limited to such a shape.

  FIG. 2 shows an exploded perspective view of the floor panel 1. FIG. 3 shows an end view taken along line AA. As shown in FIGS. 2 and 3, the floor panel 1 includes a floor structure material 2 and a floor finishing base material 3 disposed thereon.

  The floor structure material 2 includes, for example, a bottom plate 5 made of plywood and the like, and a frame member 6 fixed to the upper surface of the bottom plate 5 and its periphery.

  The bottom plate 5 has, for example, a rectangular shape that is equal to the outer dimension of the floor panel 1. The frame member 6 is made of, for example, a wood-based square member, and is fixed to the upper surface and the outer peripheral portion of the bottom plate 5. In the present embodiment, frame members 6 and 6 are arranged in parallel on each side of the bottom plate 5. Thereby, the floor structure material 2 is formed with a concave portion 11 having a rectangular shape in plan view surrounded by the frame material 6. The thickness and material of each member can be selected so that the floor structure material 2 can exhibit bending rigidity and torsional rigidity required as a flooring material. However, the specific specification of the floor structure material 2 is not limited to such an embodiment.

  The floor finishing base material 3 forms a base of the floor surface, and a floor finishing material (not shown) such as a flooring material or a resin carpet is attached to the upper surface thereof.

  At least a part of the floor finishing base material 3 has a movable portion 8 supported on the floor structure material 2 via a vibration absorber 9 so as to be movable in the vertical and horizontal directions. As a preferable aspect, the floor finishing base material 3 of the present embodiment includes a movable portion 8 and a fixed portion 7 that is fixed to the floor structure material 2 so as to be immovable. The fixing portion 7 of the present embodiment is fixed to the upper surface of the frame member 6 of the floor structure material 2 with a screw or an adhesive.

  The movable portion 8 is made of, for example, a substantially rectangular plywood in plan view, and is disposed in the concave portion 11 of the floor structure material 2. A vibration absorber 9 is disposed between the movable portion 8 and the floor structure material 2. Thereby, the movable part 8 is distribute | arranged without contacting the bottom plate 5 of the floor structure material 2 in the up-down direction. Similarly, the movable part 8 is arranged without making direct contact with the frame member 6 of the floor structure material 2 in the horizontal direction.

  FIG. 4 shows a partially enlarged view of FIG. As shown in FIG. 4, the vibration absorber 9 includes, for example, a massive rubber-like elastic body and is fixed to the floor structure material 2. The vibration absorber 9 is fixed in the recess 11 and on the upper surface of the bottom plate 5. The vibration absorber 9 is fixed to the bottom plate 5 with, for example, screws 18. Instead of screws, an adhesive may be used. Similarly, the vibration absorber 9 and the movable portion 8 are fixed using, for example, an adhesive.

  As shown in FIG. 3, in the present embodiment, a plurality of vibration absorbers 9 are provided, but the present invention is not limited to such a mode. The vibration absorber 9 is not limited to a rubber-like elastic body. For example, various materials can be used as long as they can convert vibration energy into heat energy, such as a resin, an elastomer, a spring material, or a composite thereof. Can be employed.

  The floor panel 1 configured as described above is used as a vibration-proof panel that does not transmit vibration generated by the vibrating body b such as a washing machine or a dishwasher to other panels. That is, in a preferred embodiment, the vibrating body b is placed on the movable part 8. The vibration generated by the vibrating body b is transmitted to the movable portion 8. Since the movable part 8 is supported so as to be movable in the vertical direction and the horizontal direction with respect to the floor structure material 2, a part of the vibration of the movable part 8 is thermal energy when the vibration absorber 9 is compressed or sheared. In addition to being absorbed, the transmission of vibration to the floor structure material 2 is reduced. Therefore, the floor panel 1 of the present embodiment suppresses the propagation of vibration (fixed propagation sound) of the vibrating body b, and the vibration transmission to the bedroom or living room is mitigated.

  In order to exhibit the above-described effects more effectively, the vibration absorber 9 is provided on the outer peripheral side of the movable part 8 (in the case where the movable part 8 is rectangular, as shown in FIG. Are preferably provided at each corner).

  The movable portion 8 can move in the horizontal direction within the range of the gap between the fixed portion 7 and the movable portion 8. Therefore, the momentum of the movable portion 8 can be adjusted by regulating the horizontal distance d1 of the gap. This is useful for effectively preventing, for example, the movable part 8 from being damaged by vibration or the like when the floor panel 1 is transported. The distance d1 of the gap can be appropriately determined according to the target vibrating body b, but is preferably about 5 to 15 mm, for example.

  Further, in order to prevent foreign matter from entering from the gap between the fixed portion 7 and the movable portion 8, it is desirable that a packing 10 that can be elastically deformed following the displacement of the movable portion 8 is attached to the gap. .

  In the above embodiment, the floor finishing base material 3 is composed of the fixed portion 7 and the movable portion 8. However, in other embodiments of the present invention, the floor finishing base material 3 is entirely formed of the movable portion 8. Can be done. Thereby, the area of the movable part 8 becomes large, for example, a larger washing machine etc. can be set | placed on it.

  FIG. 5 shows a floor panel 1 according to another embodiment of the present invention, in which (a) is a plan view thereof and (b) is an end view taken along line BB of (a). For elements not specifically described in this embodiment, the description of the previous embodiment can be applied as it is. Further, related or common elements are denoted by the same reference numerals as in the previous embodiment. As shown in FIG. 5, the floor panel 1 of this embodiment includes a first absorber 15 and a second absorber 16 as the vibration absorber 9.

  The first absorber 15 supports the movable part 8 in a first vertical load range that acts on the movable part 8. On the other hand, the second absorbent body 16 can support the movable portion 8 together with the first absorbent body 15 when the second vertical load range is larger than the first vertical load range.

  When the vibrating body b is a washing machine, the weight varies greatly between when the washing machine is large and small, or when the amount of laundry is large and small, for example. Since the vibration energy is proportional to the mass of the vibrating body, it is desirable to increase the vibration absorption effect accordingly when the weight of the vibrating body increases. In this embodiment, when the load acting on the movable part 8 is small (first vertical load range), the first absorber 15 absorbs vibration, while the load acting on the movable part 8 is large (second Vertical load range), both the first absorber 15 and the second absorber 16 can absorb vibration. Thereby, according to the increase in the applied load to the movable part 8, vibration absorption performance can also be improved.

  Such an action can be realized using various methods. An example is shown in FIG. In this embodiment, when the lower surface of the movable part 8 is substantially horizontal and nothing is placed on the movable part 8, the upper surface of the first absorber 15 is higher than the upper surface of the second absorber 16. positioned. The upper surface of the first absorber 15 is fixed to the lower surface of the movable portion 8, while the upper surface of the second absorber 16 is located below the upper surface of the first absorber 15. Thereby, the second absorbent body 16 is separated from the lower surface of the movable portion 8.

  FIG. 6A shows a cross-sectional view of the floor panel when a load in the first vertical load range is applied to the movable portion 8. As shown in FIG. 6A, in the first vertical load range, even if the first absorber 15 is compressively deformed, the upper surface of the second absorber 16 is separated from the movable portion 8.

  FIG. 6B shows a cross-sectional view of the floor panel when a load in the second vertical load range is applied to the movable portion 8. As shown in FIG. 6B, in the second vertical load range, the first absorbent body 15 is further compressed, and the second absorbent body 16 and the movable portion 8 come into contact with each other. Thereby, the movable part 8 is supported by both the 1st absorber 15 and the 2nd absorber 16, and a more suitable vibration absorption effect is acquired.

  The first absorber 15 is desirably provided on the outer peripheral side of the movable portion 8 with respect to the second absorber 16 as in the present embodiment. In this embodiment, the first absorbent body 15 is compressed and deformed to a greater extent than the second absorbent body 16, and therefore can generate a larger vertical reaction force than the second absorbent body 16. This is useful for suppressing the rotational moment of the movable portion 8 around the horizontal axis more effectively and suppressing the vibration of the vibrating body b.

  In the present embodiment, the same vibration absorber is employed for the first absorber 15 and the second absorber 16. Thereby, productivity of the floor panel 1 and maintenance at the time of vibration absorber replacement | exchange are improved. Different vibration absorbers may be used for the first absorber 15 and the second absorber 16 as necessary.

  On the other hand, the bottom surface 12 of the concave portion 11 of the floor structure material 2 is positioned lower than the first bottom surface 13 to which the first absorber 15 is fixed and the second bottom surface 16 to which the second absorber 16 is fixed. A second bottom surface 14. Thereby, the upper surface of the first absorber 15 can be positioned higher than the upper surface of the second absorber 16.

  As another embodiment, the first absorbent body 15 and the second absorbent body 16 may be different from each other in composition and thickness. As still another embodiment, the lower surface of the movable part 8 is formed non-flat, only the movable part 8 and the first absorber 15 are in contact with each other in the first vertical load range, and the movable part is in the second vertical load range. 8 may be configured such that both the first absorber 15 and the second absorber 16 are in contact with each other. These can be employed in various combinations.

  FIG. 7 shows a floor panel 1 according to still another embodiment of the present invention, in which (a) is a plan view thereof and (b) is an end view taken along the line CC of (a). For elements not specifically described in this embodiment, the description of the previous embodiment can be applied as it is. Further, related or common elements are denoted by the same reference numerals as in the previous embodiment.

  As shown in FIG. 7, in the floor panel 1 of this embodiment, the vibration absorber 9 (the first absorber 15 and the second absorber 16) is continuous in an annular shape. In such an embodiment, the movable portion 8 can be supported in a wider range and large vibration energy can be effectively absorbed.

  As mentioned above, although especially preferable embodiment of this invention was explained in full detail, this invention is not limited to embodiment of illustration, It can deform | transform and implement in a various aspect.
