[0092]

2. Description of the Related Art The floors of buildings other than houses are required to have a rather permanent durability, and the safety, comfort, and habitability of a user of the building tend to be overlooked. However, recently, consumers' needs for improving the living environment have been diversified, and it has been required to provide a more comfortable floor environment according to the difference in use.

With the aging society, local governments are constructing medical and welfare facilities. Facilities used for this purpose are used to accommodate, care for, and examine physically challenged people (patients and the elderly), but the elderly are susceptible to fracture when falling due to their fragile bones. There's a problem. In order to suppress the occurrence of such accidents in advance and reduce the number of occurrences, there is a strong demand for cushioning performance as floor performance and safety in a fall collision. Also, considering that healthy people such as doctors and nurses work, floor hardness that makes healthy people less tired is also required.

Further, floors of education and welfare facilities such as schools, kindergartens and nursery schools need to have a cushioning structure and a floor structure having safety at the time of falling collision. Gymnasium floors are used under intense exercise conditions, so the materials and structures used in them need to have high durability, elasticity, cushioning, and resilience in consideration of exercise functionality and safety. For this reason, JIS A 6519 defines optimum conditions for the hardness and elasticity of the gymnasium floor. According to this JIS, a 5 kg weight is freely dropped from a height of 80 cm and collides with a floor via a rubber spring to obtain vibration, floor displacement and deformation energy of the floor, and to measure cushioning and elasticity. According to this rule, the elasticity is 0.0 to 1.378 at the maximum, -0.2 to 1.378 at the minimum,
The head impact force when falling during exercise is 100 G or less. It is clear that if the value is out of the range of the standard value, the rate of occurrence of injury accidents during exercise such as Achilles key cutting, flesh breaking, and misalignment increases.

Further, with the two-day work week and the reduction of working hours, school gymnasiums are often used for local residents for multiple purposes. In winter, it is becoming indispensable to heat school gymnasiums. . However, in many cases, the gymnasium does not have any thermal insulation, and even if a heating facility is introduced, it is not efficient because it is not heat-insulated, and its function cannot be fully demonstrated. . Heating in the gymnasium is gradually improving, but the main method is radiation heating. However, in a building with a high ceiling, such as a gymnasium,
There are problems that it takes time to warm up, only the ceiling warms up, dew condensation occurs on the ceiling surface, the peripheral part of the facility and the wall are warm, but the central part does not. From the above situation, the heating equipment is not used even if it is present.

Floor heating is becoming increasingly popular, especially in ordinary houses, as a method of heating head and foot heat, which improves comfort in a living environment and reduces heating costs. However, the current method was developed for relatively small floors, such as general houses, and for floors with a large area, such as a gymnasium, where intense exercise is performed, strength and durability, pipe breakage, water leakage Cannot be used due to problems such as lack of elasticity. The method of embedding a hot water pipe in a concrete floor slab is suitable for large-area floors, but cannot be applied to floors requiring elasticity and cushioning properties, such as a gymnasium, because they are too hard.

Further, in recent years, the population has been concentrated in urban areas, and the construction of a gymnasium on the upper floor has been considered. However, at present, soundproofing of the floor and development of soundproofing materials and structures for reducing the impact sound of heavy floors are sufficient. Construction is not progressing.

As described above, the floor structure is required to have different performance depending on its use, but at present, such a need has not been met.

[0099]

SUMMARY OF THE INVENTION The present invention relates to a floor structure having floor performance such as cushioning, elasticity, soundproofing and floor heating.

[0010]

[Means for Solving the Problems] Floors of facilities for education, medical care, welfare and the like are required to have appropriate elasticity, cushioning property, and safety at the time of a fall collision suitable for the purpose of use. For that purpose, a floor structure having floor performance such as elasticity and cushioning that is suitable for floor use is required. As a method thereof, it is effective to provide the floor with cushioning properties and adjust the floor hardness. A rubber chip panel composed of rubber chips and small pieces of wood is a material whose elasticity, cushioning property and hardness can be adjusted by changing the compounding ratio, specific gravity, and thickness. When applied to various floor structures using this, it is possible to propose a floor structure suitable for the purpose of use. The rubber chip panel can be grooved at the time of hot-press molding, and a floor heating function can be provided by laying a hot water pipe in the groove. Therefore, the floor structure and floor heating have a large area such as gymnasiums, schools, kindergartens, and welfare facilities, and the floor structure does not lack the cushioning and resilience properties that make up the elasticity, and the impact force when falling is reduced. Structure. In order to complete the structure, bundles, pulls, and joists are sequentially assembled on a base, and a floor structure with a base material and a finishing material laid on the joists, a structural plywood and a rubber chip and a wood piece on it. It is necessary to construct a rubber chip panel made of the above, and further lay a finishing floor material thereon. At that time, in order to satisfy performances suitable for various floor uses, it is important to select rubber chip panels having appropriate specific gravities, compounding ratios and different thicknesses.
In addition, in order to provide a floor heating function, a grooved panel (thickness 12 to 10) in which a hot water pipe can be embedded in a rubber chip panel is used.
25 mm) is required, and the hot water pipe is fitted with a pipe having a thickness of 9 to 17 mm in the groove of the rubber chip panel. Further, in order to efficiently transmit the temperature of the hot water to the floor, a heat radiating plate (thickness: 50 μm) made of aluminum having good heat conductivity is bonded onto the rubber chip panel. Next, a floor finishing material is bonded onto the heat sink to complete the floor structure.

[0011]

Floor structure of the action of the present invention is a rubber tip panel of rubber chips and wood pieces between the floor structure and the floor covering up material is interposed, appropriate elasticity as floor motor functionality, floor safety
The present invention relates to a floor structure having a moderate cushioning property as a property and a hardness at the time of a fall collision. Therefore, the rubber chip panel made of rubber chips and wood chips used for that purpose has elasticity, depending on the specific gravity, thickness and the mixing ratio of the raw materials.
Since the values such as the buffering property are different, it is necessary to select a panel suitable for the required floor use, and the values are as shown in Tables 1 and 2 below. In addition, the compounding ratio of Table 2 shows rubber chip: woody piece: adhesive (weight ratio). From this value, a panel can be arbitrarily selected according to the configuration of the floor base. It is also possible to form a groove on the upper surface side of this rubber chip panel , attach a hot water pipe, and provide a floor heating function. This is because the rubber chip panel is a resilient material,
This is because there is no damage to the hot water pipe even under conditions such as intense exercise. The heat sink is placed for the purpose of improving the heat conduction from the hot water pipe and heating the floor uniformly,
Since the temperature difference between the pipe and the pipe is about 3 to 4 ° C., it is determined whether or not the heat radiating plate is arranged depending on the floor area, weather conditions and the like. There is no change in elasticity and cushioning property depending on the presence or absence of the heat sink. Also, the rubber chip panel, as described above,
Since it has the effect of alleviating various impact forces applied to the floor, the generation of sound due to heavy floor impact is suppressed. As a result, an improvement amount of 5 to 10 dB is obtained, and the floor noise on the floor of the gymnasium on the floor is reduced.
