  The present invention relates to a floor structure in which a finishing plate is provided on a floor slab.

  There is known a floor structure in which a mixed material layer is formed on a floor slab, and a finishing plate formed of stone or the like is disposed on the mixed material layer (see, for example, Patent Document 1). The mixed material is a so-called cement paste in which water and cement are mixed, and the mixed material layer is a so-called self-leveling layer.

JP 2001-132216 A (see paragraph 0002 etc.)

In the case of a conventional floor structure, the impact sound cannot be reduced because the floor slab and the finishing plate are joined by the mixed material layer.
The present invention provides a floor structure excellent in soundproofing performance.

Since the floor structure according to the present invention includes the floor slab, the rubber component provided on the surface of the floor slab, and the finish plate provided on the surface of the rubber component, the rubber component is provided. A floor structure excellent in soundproofing effect can be provided.
The floor structure according to the present invention includes a floor slab, a rubber component provided on the surface of the floor slab, a reinforcing base plate provided on the surface of the rubber constituent, and a finish plate provided on the surface of the reinforcing base plate. Therefore, the floor structure excellent in soundproofing effect can be provided by providing the rubber component.
Since the rubber component is composed of a plurality of rubber plates arranged at intervals in the direction along the surface of the floor slab, the floor structure can have spring performance and the floor structure can be made more easily swayed. In addition, the vibration reduction performance can be improved and a floor structure with a high soundproofing effect can be obtained.
A floor structure according to the present invention is a floor structure in which a plurality of floor panels are provided on the surface of a floor slab so as to be adjacent to each other with a gap forming a joint, and the joint is filled with a filler. The floor panel is provided on the back surface of the reinforcing base plate and the panel portion formed by adhering the surface of the reinforcing base plate and the back surface of the finish plate formed to the same size as the reinforcing base plate with an adhesive. The rubber component is composed of a plurality of rubber plates spaced from each other on the back surface of the reinforcing base plate, and the surface of the plurality of rubber plates and the back surface of the reinforcing base plate are Since it is bonded with an adhesive and the back surface of the plurality of rubber plates and the surface of the floor slab are bonded with the adhesive, the floor structure has spring performance, and the floor structure can be made a structure that is more easily shaken. Improves vibration reduction performance and is soundproof It can be a high floor structures.
Since the filler is a silicon-based sealant, the silicon-based sealant causes the movement of the one floor panel when a load is applied to the other floor panel adjacent to the other, while the other floor panel is adjacent to the other floor panel. The floor structure is excellent in following performance for following the floor panel, and in restoring performance for restoring the floor panel to the original position when the load on the floor panel is removed.
Since the adhesive that bonds the back of multiple rubber plates and the surface of the floor slab is a two-component adhesive consisting of a main agent and a curing agent, the adhesive flows into the gap between the rubber plate and the rubber plate. Since it becomes difficult to suppress the adhesion between the back surface of the reinforcing base plate and the surface of the floor slab due to the adhesive, the floor structure can be maintained in a structure that can be more easily shaken, the vibration reduction performance can be improved, and the floor structure with a high soundproofing effect. Become.
Since the rubber component is formed of rubber having an independent foam structure, the floor structure can be made to be more easily swayed, so that vibration reduction performance can be improved and a floor structure with a high soundproofing effect can be obtained.
Since the rubber component is made of rubber having a rubber hardness of 40 ° to 50 °, the floor structure can be made more easily swayed, so that the vibration reduction performance can be improved and a floor structure with a high soundproofing effect can be obtained.

It is the board | substrate multilayer structure formed in the rectangular shape of predetermined thickness by adhere | attaching.
The finishing plate 8 is a marble plate having a rectangular shape, for example, a square shape with a side length of 400 mm and a thickness of 3 mm.
The reinforcing base plate 6 is a tile plate formed in a rectangular shape, for example, a square shape with a side length of 400 mm and a thickness of 9 mm.
And the panel part 4 is a structure formed in the rectangle, for example, square shape whose length of one side is 400 mm, and thickness is 12 mm + (alpha) (layer thickness of the adhesive agent 7).

  As shown in FIG. 3 and FIG. 4, the rubber component 5 is configured by intermittently providing, for example, a plurality of rubber plates 5 </ b> A on the back surface 6 b of the reinforcing base plate 6. For example, the length of one side facing each other is the same as the length of one side of the back surface 6b of the reinforcing base plate 6, and the length of the other side facing each other is the length of one side of the back surface 6b of the reinforcing base plate 6 The back surface of the reinforcing base plate 6 is a rectangular rubber plate 5A that is shorter than the length and has a predetermined thickness (for example, 5 mm to 10 mm), and a plurality of rubber plates 5A are adjacent to each other with an interval c of 50 mm to 60 mm. 6b and the surface 5a of the rubber plate 5A are bonded with an adhesive 9.

For example, as shown in FIGS. 3 and 4, a rubber plate having a long side length a = 400 mm, a short side length b = 58 mm, and a thickness h = 5 mm is provided on the back surface 6b of one reinforcing base plate 6.

The floor panel 3 and the other floor panel 3 adjacent to each other have excellent tracking performance, and when the load on the floor panel 3 is removed, the floor panel 3 can be restored to its original position. Structure 1 is obtained. Further, a silicon-based sealing agent is preferable because it does not discolor the finishing plate 8 over time and is easy to clean.

  In other words, the floor structure 1 completed in this way is composed of a floor slab 2 and a rubber formed by a plurality of rubber plates 5A that are intermittently installed at intervals c in the direction along the surface 2a of the floor slab 2. The structure includes a component 5, a reinforcing base plate 6 provided on the surface 5 a of the rubber component 5, and a finishing plate 8 provided on the surface 6 a of the reinforcing base plate 6.

  In addition, in the above, in each board 5A; 6; 8 which comprises the floor panel 3, when the floor structure 1 is comprised, let the board surface near the floor slab 2 be a back surface, and the side far from the floor slab 2 The plate surface is described as the surface.

The measurement results of the performance test of the floor structure of Embodiment 1 are shown in FIGS.
In the test, a floor panel 3 having a square shape with a side of 400 mm and a rubber plate 5A arranged at a predetermined thickness as shown in FIG. 3 is vertically and horizontally placed on a floor slab 2 having a reinforced concrete structure with a thickness of 150 mm. The floor structure 1 is installed in three rows with a joint width of 3 mm apart, and a tapping machine (hammer hitting machine) (not shown) is installed at the center of the surface 8a of the finishing plate 8 of the floor structure 1 with a tapping machine. The surface impact sound level reduction amount was measured by striking the surface 8a of the finishing plate 8.

The test body 1 has a configuration in which a rubber plate (rubber hardness 45 °) formed of a hard rubber having a thickness of 10 mm is used as the rubber plate 5A.
The test body 2 has a structure using a rubber plate (rubber hardness 50 °, density 0.30 ± 0.03 g / cm ³ ) as a rubber plate 5A, which is called a 6 mm thick rubber sponge. is there.
The test body 3 has a structure using a rubber plate (rubber hardness 40 °, density 0.25 ± 0.03 g / cm ³ ) as a rubber plate 5A, which is called a 6 mm-thick rubber sponge. .
The test body 4 has a configuration in which a rubber plate (rubber hardness 45 °) formed of a hard rubber having a thickness of 5 mm is used as the rubber plate 5A.
The test body 5 has a structure using a rubber plate (rubber hardness 50 °, density 0.25 ± 0.03 g / cm ³ ) as a rubber plate 5A, which is called a 6 mm-thick rubber sponge. .
The test bodies 1 to 5 have the following configuration. The finish plate 8 was a marble plate, the reinforcing base plate 6 was a tile plate, and the adhesives 7 and 9 were epoxy adhesives. That is, the panel part 4 used the panel (Brand name "MT panel", the product made from ESGJAPAN) which laminated the marble board and the tile board. As described above, a two-component adhesive (trade name “Bond EMS20”, manufactured by Konishi Co., Ltd.) in which the main agent is an epoxy resin and the curing agent is a modified silicon resin as described above was used. As the filler 12, a silicon sealing agent (trade name “Sealant 45”, manufactured by Shin-Etsu Chemical Co., Ltd.) as described above was used.

  5 and 6, it can be seen that the floor structure 1 of Embodiment 1 is particularly excellent in reducing the floor impact sound level in the frequency band of 500 Hz or higher. In addition, when the rubber plate 5A is formed of a rubber having an independent foam structure, as in the case of the test bodies 2; 3; 5, the case of using a hard rubber (test body 1; 4). It was also found that the effect of reducing the floor impact sound level in the frequency band of 500 Hz or higher is enhanced. This is considered to be due to the fact that when hard rubber is used, the rubber hardness is large, so that the performance of reducing the floor impact sound level in the frequency band of 500 Hz or higher has been suppressed. On the other hand, when rubber with an independent foam structure is used, the rubber hardness is small and the structure easily shakes. Therefore, it is considered that the effect of reducing the floor impact sound level in the frequency band of 500 Hz or higher is increased. Further, even when a rubber plate made of a rubber having an independent foam structure is used, a structure made of soft rubber having a low rubber hardness like the test body 3 has a structure that easily shakes. Therefore, it is considered that the effect of reducing the floor impact sound level in the frequency band of 500 Hz or higher is enhanced.

In addition, when rubber with an independent foam structure is used, the adhesive 9 and the adhesive 10 are less likely to penetrate into the rubber, so that the rubber is prevented from being cured by the adhesive 9 and the adhesive 10. For this reason, the floor structure 1 can be easily shaken.
According to the first embodiment, since the rubber plate 5A formed of rubber having a rubber hardness of 40 ° to 50 ° is used as the rubber plate 5A, the floor structure 1 can be made to be more easily swayed, and the floor has a higher soundproofing effect. Structure 1 can be provided.

  When a one-component adhesive is used as the adhesive 10 that bonds the back surface 5b of the plurality of rubber plates 5A and the surface 2a of the floor slab 2, the adhesive 10 can easily enter the gap c (easily wrap around). The adhesive 10 may enter the space c, and the back surface 6b of the reinforcing base plate 6 and the surface 2a of the floor slab 2 may be bonded by the adhesive 10, and thus the back surface 6b of the reinforcing base plate 6 And the surface 2a of the floor slab 2 are bonded to each other by the adhesive 10, the floor structure 1 may become a structure that does not easily shake, and vibration reduction performance may be suppressed. On the other hand, according to the first embodiment, as the adhesive 10 for bonding the back surface 5b of the plurality of rubber plates 5A and the surface 2a of the floor slab 2, two liquids in which the main agent is composed of an epoxy resin and the curing agent is a modified silicon resin. Since the adhesive 10 is used, it is difficult for the adhesive 10 to flow into the interval c (difficult to wrap around), and the interval c can be maintained, and the back surface 6b of the reinforcing base plate 6 and the surface 2a of the floor slab 2 by the adhesive 10 can be maintained. Therefore, the floor structure 1 can be maintained in a structure that easily shakes, the vibration reduction performance can be improved, and the floor structure 1 having a high soundproofing effect can be provided.
