  Hereinafter, the present invention will be described with reference to embodiments shown in the drawings. FIG. 1 is a sectional view showing a house having a floor structure according to an embodiment of the present invention, and FIG. 2 is a perspective view of a floor panel constituting a part of the floor structure of FIG. The floor structure according to the present embodiment can be used for either a detached house or an apartment house. In this embodiment, the floor structure will be described when used for a detached house. The floor structure 2 according to this embodiment is provided on a base floor 4 of a detached house 3A as shown in FIG. The detached house 3A is, for example, an outer heat insulation type house in which a ventilation layer 5 is formed on the inside of the wall and the inside of the roof of the house. ((B) of FIG. 1 shows the example which applied the floor structure 2 of a present Example to the apartment house 3B.) The basement floor 4 is a concrete floor by which the heat insulating material which is not shown in figure is arrange | positioned on the ground side. . A large number of floor panels 10 are laid on the upper surface of the base floor 4. The base floor 4 and the floor panel 10 have a double structure. As shown in FIG. 2, the floor panel 10 includes a flooring 12 that is cut to a predetermined size, and a cushioning material 11 that is bonded to the lower surface of the flooring 12 and has a ventilation gap S formed on the entire surface.

As shown in FIGS. 3 and 4, the cushion material 11 includes upper and lower mesh portions 20 and 21, and a plurality of support yarns 22 having upper and lower ends connected to the mesh portions 20 and 21, respectively. Yes. These mesh portions 20 and 21 and the support yarn 22 are made of a line material. The upper mesh portion 20 and the lower mesh portion 21 are formed with different mesh shapes. That is, as shown in FIG. 4, the upper and lower mesh portions 20 and 21 are formed in a rhombus shape in the upper mesh portion 20 and in a hexagonal shape in the lower mesh portion 21, respectively. The 21 meshes are matched so that they do not overlap. As shown in FIGS. 4 and 5, the support yarn 22 as the connecting yarn is knitted into the upper mesh portion 20 at the upper end and the lower mesh portion 21 at the lower end, and is connected side by side in a certain direction D1. That is, as shown in FIG. 3, the support yarns 22 are arranged in a reverse direction with respect to adjacent rows with the row 22F arranged side by side with the air gap S, and the upper and lower ends thereof are connected. As shown in A) and (B), the direction of inclination of the row 22F gradually changes as it progresses, and after passing through an upright state without inclination, that is, in a position where the upper and lower mesh portions 20, 21 overlap, The support yarn 22 is connected at right angles to the mesh portions 20 and 21 (see FIG. 5C), and returns to the original inclination direction again (see FIG. 5D). Thus, the change in the inclination direction is regularly repeated as the row 22F progresses. Thus, as shown in FIG. 3, in the support yarn 20, in a portion where the meshes of the upper and lower mesh portions 20 and 21 do not overlap, the vertical cross section perpendicular to the arrangement direction D <b> 1 repeats the V shape horizontally. It has a shape. The row 22F is advanced in a certain direction D1. For this reason, the support yarn 20 is a gap in which air is easy to flow in the direction D1 in which the support yarns 20 are arranged in a certain direction D1 while changing the direction of inclination sequentially according to the positions of the meshes where the upper and lower mesh portions 20, 21 are displaced. A ventilation path P is formed. The support yarns 22 are connected in a row. The yarn diameter, both end dimensions, and planting density of the support yarn 22 are preferably set so that the pressure resistance of the cushion material 11 is at least 500 kgf / m ² or more, and in this embodiment, 2,500 kgf / m ^2. It is set to become. The cushion material 11 is matched with the dimension of the flooring 12, and the length and breadth are cut into predetermined dimensions (for example, 300 mm × 300 mm, 600 mm × 600 mm, etc.) in advance.

  The material of the mesh portions 20 and 21 and the support yarn 22 in the cushion material 11 is composed of any one of organic fibers, inorganic fibers, a mixture of these organic fibers and inorganic fibers, or a blended fiber. Preferably, the cushion material 11 is made of any one of polyethylene, polypropylene, rayon, polyester, polyamide, aromatic polyamide, glass fiber, or carbon fiber. In this embodiment, polyester or nylon is used from the viewpoint of heat resistance, strength, and cost. Moreover, you may use a polypropylene from the point of lightweight and hardness. When the side surface becomes asymmetrical due to the cut, the cushion material 11 may be heat-treated and cured after melting. Moreover, you may make it harden the net | network part 21 of the cushion material 11 lower surface by heat-processing.

The support yarn 22 is knitted and connected to both net portions 20 and 21 by a double raschel knitting machine (not shown). For this reason, the cushion material 11 is a fiber structure (double raschel solid knitted fabric) having a three-dimensional structure constituted by two mesh portions 20 and 21 having front and back surfaces having a net structure and support yarns 22 connecting the both surfaces 20 and 21. ). In this embodiment, a three-dimensional structure having high support performance, structural stability, and low airflow resistance is formed, and as shown in FIGS. A truss structure in which the support yarn 22 is inclined in a direction opposite to the support yarn 22 arranged in the adjacent rows 22F and 22F is employed. The knitting of the cushion material 11 is warp knitted by a double raschel knitting machine (not shown), and the mesh portions 20 and 21 knitted by the chain knitting yarn and the insertion yarn are connected by the support yarn 22 whose direction is changed. It is like that. Since the cushion material 11 manufactured in this way forms a truss structure as a whole, when a load is applied in the thickness direction, the inclined portions in the opposite direction stick to each other so as to restrict the fall of the support yarn 22 to each other. Act on. For this reason, the shape and three-dimensional structure of the nets 20 and 21 are stable. As a result, although depending on the material, the pressure resistance in the thickness direction of the cushion material 11 was 2,500 kgf / m ² at a thickness of 1 cm, and excellent shape retention and elasticity could be realized. As described above, the floor panel 10 using the cushioning material 11 that can withstand a high load and has elasticity is capable of impact even if a light impact sound such as a tapping sound or a heavy impact sound such as a heavy fallen object is generated on the floor. It acts to attenuate and disperse sound energy instantaneously, and exhibits excellent performance as a soundproof floor. In addition, the air permeability of the cushion material 11 is as low as 100 Pa or less even at a wind speed of 5 m / sec, and the warm air can be evenly distributed over the entire surface of the cushion material 11. Good air blowing property can be ensured. The thickness of the cushion material 11 can be 1 to 3 cm depending on the design plan. Furthermore, since the support yarns 22 are knitted at a high density and the air gap is sufficiently secured in the knitting direction, the sound insulation performance is also improved.

  The non-breathable flooring 12 is cut to the same dimensions as the cushioning material 11, and the cushioning material 11 is bonded to the back surface of the flooring 12. The flooring 12 is configured by bonding a lower base material 25 and an upper finishing material 26 together. As the base material 25, a rigid panel is used in which a net of carbon fiber or glass fiber is applied and hardened with mortar. These rigid panels 25 exhibit strong support performance even with a thickness of several millimeters (3 to 4 mm). In the case of the base material 25 using carbon fiber, the carbon fiber has a far-infrared radiation function, and a warm-air guided to the cushion material 11 brings a far-infrared effect into the room. The base material 25 is not limited to the rigid panel, but a material having a far-infrared radiation function (for example, alumina, carbon, hydrotalcite, zeolite, carbon) on the lower surface of a wooden board or ceramic cement board. Coating a material having a far-infrared function of a wavelength of 4 to 1000 μm such as a fiber) or forming a sheet blended with a material having a far-infrared radiation function, and placing these sheets on the lower surface of a wood board or a ceramic cement board, You may make it laminate | stack. The finishing material 26 is appropriately selected and used according to the design plan, such as a wooden floor material, a ceramic tile or a carpet. The thickness of the floor panel 10 is set to 100 mm or less, and preferably 30 mm or less.

  In the house having the floor structure 2 according to this embodiment, the air conditioning unit 30 is connected as shown in FIGS. The air conditioning unit 30 guides the conditioned air into the room. One end of an exhaust pipe 32 is connected to the air-conditioning air outlet 31 of the air-conditioning unit 30. The exhaust pipe 32 is disposed on one side portion 4A of the base floor 4 and has a number of exhaust holes 33 and the other end 34 closed. When the air-conditioning air is led from the air-conditioning air outlet 31 of the air-conditioning unit 30 to the exhaust pipe 32, the air-conditioning air is exhausted from the exhaust hole 33 along the upper surface of the base floor 4. For this reason, when the floor panel 10 is placed on the upper surface of the base floor 4 with the cushioning material 11 facing downward and the ventilation path P is aligned with the exhaust direction of the exhaust hole 33, the air-conditioning air is guided to the ventilation path P. It has become. That is, the floor panel 10 is laid so that the air flow direction D <b> 1 of the ventilation path P of the cushion material 11 matches the air discharge direction from the exhaust hole 33. A sealing material (peripheral closing portion) 35 is bonded to the side surface (outer peripheral surface) of the cushion material 11 facing both side portions 4B and 4C adjacent to one side portion 4A of the base floor 4 and the side portion 4B of the base floor 4 is provided. 4C prevents air-conditioning air from leaking into the room. The side surface of the cushioning material 11 facing the exhaust pipe 32 facing the one side portion 4A of the base floor 4 is open and constitutes the air introduction opening portion 11A. The side surface of the cushioning material 11 facing the side portion 4D facing the one side portion 4A of the base floor 4 is open and communicates with the wall ventilation layer 5 of the outer heat insulating house to form an air discharge opening portion 11B. Yes. For this reason, the air-conditioning air from the air-conditioning unit 30 is led from the air-conditioning air outlet 31 to the cushion material 11 via the exhaust pipe 32, flows through the ventilation path P1 of the cushion material 11 along the ventilation direction D1, and discharges the air. It is discharged from the opening 11B to the wall ventilation layer 5. For this reason, the air-conditioning air flows uniformly over the entire floor panel 10 laid.

  Next, the operation of the floor panel 10 according to the above embodiment and the floor structure 2 using the floor panel 10 will be described. In the floor panel 10 according to the above embodiment, when the floor panel 10 is laid on the base floor 4, a layer of the cushion material 11 is formed between the base floor 4 and the floor material 12. This cushion material 11 layer is configured so that the support yarns 22 connected to the upper and lower mesh portions 20 and 21 are arranged in a row in a certain direction D1 while changing the direction in which the support yarns 22 are sequentially inclined. The support yarns 22 are supported in different directions. For this reason, the load is dispersed throughout and the occurrence of subduction is suppressed. Therefore, a comfortable walking sensation can be obtained. Moreover, since many support yarns 22 exist in the layer of the cushion material 11, the sound insulation performance is improved. Further, since the support yarn 22 is connected to the upper and lower mesh portions 20 and 21 arranged in a shifted manner, an air passage P through which air flows is formed in the direction D1 in which the support yarns 22 are arranged. For this reason, even if the floor receives an impact and generates an impact sound, the air that transmits the vibration wave due to the impact not only passes through the ventilation gap S between the support yarns but also diffuses through the ventilation path P. Can be attenuated, and soundproofing is improved. Further, the inclination of the support yarn 22 changes in small increments due to the shift of the mesh, and since the inclination direction is opposite to that of the adjacent rows 22F and 22F, the pressure resistance strength is improved. In other words, the vertical load applied to the floor panel 10 is supported by the structure of the assembly material in which the upper and lower mesh portions 20 and 21 are horizontal members and the support yarn row 22F is an oblique material and the two are combined. The pressure strength is improved. Therefore, not only the thickness of the cushion material 11 can be reduced, but also the material of the cushion material 11 can be a lightweight material.

Next, the operation of the floor structure 2 using the floor panel 10 according to the above embodiment will be described. In the floor structure 2 according to the above embodiment, when the warm air of the air-conditioning air sent from the air-conditioning unit 30 is guided to the exhaust pipe 32 from the air-conditioning air outlet 31, the cushion material 11 is released from the exhaust hole 33 of the exhaust pipe 32. The air is introduced into the air introduction opening 11A. The warm air further passes through the ventilation gap S mainly through the ventilation path P of the cushion material 11 laid down, and is discharged to the wall ventilation layer 5 from the air discharge opening 11B. It is discharged to the outside via. At this time, since the warm air of the air-conditioning air flows uniformly over the entire surface of the floor panel 10 laid out, the room is heated uniformly. Moreover, since the base material 25 of the floor material 12 of the floor panel 10 is composed of a rigid panel that is solidified and hardened with carbon fiber and zeolite aggregate, the far-infrared radiation effect is brought about by the carbon fiber and zeolite. As a result, the heating efficiency is improved and the heating of the entire room is made uniform. In addition, since the cushioning material 11 has a compressive strength set to 2500 kgf / m ² , it does not sink even when furniture is placed, and even when walking on the floor panel 10, sinking occurs. A comfortable walking sensation can be obtained. Further, tapping noises during walking and impact sounds when an object falls are absorbed by the cushion material 11, so that grooves are provided on the back surface of the floor panel or a flexible foamed resin sheet is laid as in the prior art. Sound insulation performance is improved compared to the case. Furthermore, since only the floor panel 10 at the target location can be replaced during repair or collection, maintainability is improved. Also, when installing the floor panel on the basement floor as in the past, it is not necessary to dispose support legs and support pillars, and the construction is completed simply by laying the floor panel 10 on the basement floor 4. Work efficiency and cost reduction can be achieved. Furthermore, since the air-conditioning air is discharged to the outside through the roof ventilation layer, it contributes to the melting of snow on the roof in the snowfall area.

  The present applicants actually manufactured a test body (three-dimensional solid net) I having a warp knitted and knitted solid truss structure as a cushioning material 11, and its pressure strength, compression elasticity. The coefficient was measured and evaluated according to JISK6385-2001.

The test body I was set to a thickness of 10 mm, a product basis weight of 665 g / m ² , and a test body size of 100 (l) × 100 (W) × 10 (t) mm.

  In addition, the ventilation resistance of the three-dimensional solid net was measured and evaluated in accordance with JIS B 9908. In the test body II, a three-dimensional solid net was laminated in layers. The size of the specimen II was 19 × 19 × 20 cm. As a result of measurement and evaluation, it was found that the pressure loss was 35 Pa at a wind speed of 5 m / sec and the ventilation load was low.

A test body III composed of a three-layer board was manufactured as the base material 25 of the flooring 12. In this test body III, the composition of the core layer board in the center is 55 wt% early-strength cement, 20 wt% pearlite, 3 wt% surface-treated carbon chopped fiber, 20 wt% synthetic zeolite, and 2 wt% cement admixture. The raw material with a blend composition of 65% by weight early cement, 30% by weight of synthetic zeolite, 3% by weight of surface-treated carbon chopped fiber, and 2% by weight of cement admixture was mixed with water, and the upper layer: core layer: lower layer = 1: 2: 1 A ceramic cement board with a thickness of 20 mm was produced. As a result of the measurement, the bending strength of the board after 2 weeks 350 kgf / cm ² (35 N / mm ² ), the compressive strength 800 kgf / cm ² (80 N / mm ² ), and the wavelength of the raw material powder by a spectrophotometer 4 to 1000 μm The emissivity (compared with a black body) was 70 to 90%, indicating that it has far-infrared radiation.

  A test body IV of a vinyl chloride resin floor material sheet was manufactured as the base material 25 of the floor material 12. In this test specimen IV, a composition comprising 44 wt% of vinyl chloride resin, 15 wt% of DOP plasticizer, 35 wt% of synthetic zeolite, 5 wt% of epoxy soybean oil, and 1 wt% of stabilizer was mixed at a temperature of 150 to 160 ° C. with a kneading mixer. The mixture was kneaded for 20 to 30 minutes, and then a vinyl chloride flooring sheet having a thickness of 3 mm was produced with a heating and rolling roller at 170 ° C. The measurement evaluation based on JISK7204 was a wear amount of 420 mg by a Taber tester (1000 g, 1000 revolutions). It was shown to have far-infrared radiation with a dimensional stability of 0.07 mm and an emissivity of 70 to 90% according to JISA5705 (treated at 70 ° C. for 24 hours).

  As a base material 25 of the flooring 12, a test body V was manufactured by coating a ceramic floor board on the back surface of a commercially available flooring material. In this test body V, a composition obtained by kneading 63 wt% early-strength cement, 5 wt% surface-treated carbon chopped fiber, 30 wt% synthetic zeolite, and 2 wt% cement admixture with water was placed on the back of a 12.3 mm-thick commercial flooring material. After 3 mm coating, it was dried. The far-infrared emissivity of the back coat layer was 70 to 90%.

Next, in order to evaluate the soundproof performance and heating performance of the floor structure 2, the following three types of floor structures were actually constructed and tested.
(1) Type A floor structure Two 10 mm thick cushioning materials used in the test body I described in Example 2 above are bonded to a concrete base floor (slab thickness 150 mm) to form a three-dimensional solid net with a thickness of 20 mm. Was laid with a floor area of 2.5 × 2.5 m (cushion material dimensions, 2,500 (l) × 2,500 (W) × 20 (t) mm). Next, the ceramic cement board having a thickness of 20 mm of the test body III described in Example 3 is disposed on the upper surface of the cushion material as the base material 25, and further, a nylon pile type having a thickness of 7 mm that is commercially available as the finishing material 26. A tile carpet was arranged on the upper surface of the ceramic cement board to make a floor structure having a floor height of 47.0 mm.
(2) Type B floor structure A 10 mm thick three-dimensional three-dimensional net is bonded to a concrete base floor (slab thickness of 150 mm) by bonding two 10 mm thick cushioning materials used in the specimen I described in Example 2 above. Was laid with a floor area of 2.5 × 2.5 m (cushion material dimensions, 2,500 (l) × 2,500 (W) × 20 (t) mm). Next, a PVC flooring sheet having a thickness of 3 mm of the test specimen IV described in Example 4 was used as the base material 25 and lined with a commercially available wooden flooring material having a thickness of 12.3 mm. The laminated base material 25 is disposed on the upper surface of the cushion material, and a nylon pile tile carpet having a thickness of 7 mm, which is commercially available as a finishing material 26, is disposed on the upper surface of the laminated wooden flooring material, The floor structure was 42.3 mm.
(3) Type C floor structure A two-ply 10 mm thick cushioning material used in the specimen I described in Example 2 above is bonded to a concrete base floor (slab thickness 150 mm) to form a three-dimensional solid network with a thickness of 20 mm. Was laid with a floor area of 2.5 × 2.5 m (cushion material dimensions, 2,500 (l) × 2,500 (W) × 20 (t) mm). Next, a flooring material having a thickness of 15.3 mm of the test body V described in Example 5 and coated with a ceramic cement-based board on the back surface is disposed on the upper surface of the cushion material as a base material 25, and further, a finishing material. A nylon pile tile carpet having a thickness of 7 mm, which is commercially available as No. 26, was placed on the upper surface of the flooring material coated on the back surface to form a floor structure having a floor height of 42.3 mm.
The soundproofing performance of types A to B was measured and evaluated by applying impact to the floor surface with a tapping machine and a bang machine, and impact sound attenuated in a corresponding room downstairs. The measuring method was implemented based on JISA1418 (measurement of the floor impact sound level in the building site). In addition, the floor sink test with furniture and the performance of walking feeling were also evaluated. The obtained results are shown in Table 1.

  From the results of Table 1, it was revealed that any of the types A to C has a high sound insulation effect against the floor light weight impact and the floor weight impact. Moreover, even if the furniture weight reached the load of 500 kg about type A and B, deep subduction was not seen in the range of subtraction amount of 0.5-1.0 mm. It became clear that both the feeling of walking and types A to C were comfortable.

Next, an experiment was conducted in which warm air was blown on the floor structure of types A to C and the floor structure of type C and the type D floor structure in which the back surface of the flooring material was not coated with the ceramic cement board. . The type D floor structure is as follows.
(4) Type D floor structure Two 10 mm thick cushioning materials used in the test specimen I described in Example 2 above are bonded to an existing concrete base floor (slab thickness 150 mm) to form a three-dimensional 20 mm thick A three-dimensional net was laid with a floor area of 2.5 × 2.5 m (size of cushion material, 2,500 (l) × 2,500 (W) × 20 (t) mm). Next, a commercially available flooring material is placed on the upper surface of the cushion material as the base material 25, and further, a 7 mm thick nylon pile tile carpet marketed as the finishing material 26 is coated with nothing on the back surface. A floor structure with a floor height of 27.0 mm was placed on the upper surface of a non-flooring material. That is, the type D floor structure does not include a far-infrared radiator.
In the hot air blowing experiment, a duct was connected to the casing discharge part of the air blower of the air conditioning unit, and hot air of 70 ° C. was blown from the duct to the cushion material for the type A to D floor structures. The temperature at a position 80 cm above the floor surface was measured by measuring the temperature continuously by connecting a K thermocouple and a globe-type thermometer to the data logger. Table 2 shows the results obtained in the steady state.

  From the results of Table 2, the thermocouple measurement temperature is in the range of 25.1 to 25.5 ° C. for the floor structures of types A to C having the far-infrared radiator on the base material 25 of the floor panel 10. On the other hand, Type D which does not have a far-infrared radiator has a difference of 23.8 ° C. and 1 ° C. or more. In the globe-type thermometer, the floor structures of types A to C having a far infrared radiator are in the range of 23.4 to 23.5 ° C., but do not have a far infrared radiator. Type D showed a difference of 23.2 ° C. and 0.2 or 0.3 ° C. From this, the effect of radiant heat by far infrared rays was recognized.

Furthermore, although the floor panel is configured by bonding the cushion material 11 and the floor material 12, the present invention is not limited to this, and the cushion material 11 and the floor material 12 are applied in separate processes without being bonded to each other. You may do it. It is preferable to bond both the floor material 12 and the cushion material 11 as one of the methods. Moreover, in the said Example, the cushion material 11 forms the mesh of the upper side net | network part 20 in a rhombus shape, and the shape of the lower side net | network part 21 in a hexagonal shape, respectively, and makes the shape of the upper and lower net | network parts 20 and 21 different. However, the present invention is not limited to this. Needless to say, the same mesh may be formed, the shape may be the same, and the sizes may be different. Further, in the above embodiment, the meshes of the upper and lower mesh portions 20 and 21 are not overlapped, but this is not limited to this, and the support yarns are sequentially changed in a certain direction between the upper and lower mesh portions. Needless to say, the upper and lower mesh portions may be arranged so as to overlap each other as long as they can be arranged side by side. Furthermore, in the said Example, the space | interval of the connection part with a net | network part of a support thread | strain is narrow in the space | interval with one connection part of the row | line | column which adjoins, the space | interval of the other row | line is widened, and the shape which repeats a cross-sectional V-shape horizontally However, the present invention is not limited to this, and a plurality of columns may be inclined in the same direction, and a plurality of adjacent columns may be inclined in the opposite direction. In addition, the cushion material 11 is arranged with the mesh portions 20 and 21 above and below, but is not limited to the mesh member, and as a top and bottom material to which the upper and lower ends of the support yarn are coupled, You may make it use the cloth-like material in which many small holes were formed.
