Description

[Detailed description of the invention] [Industrial application field] The invention relates to a wooden sound-insulated heating floor.

[Prior Art] As shown in Fig. 1, there is a conventional method of heating floors, in which a joist (b) and a heat insulating material (e) are placed on a concrete floor base (11). And heating panel (A) is mounted on it via a plywood disc (a), on which carpet or carpet or wood board (c)
And the like. Here, (d) is a peg, and (e) is glass wool, rock wool or the like.

By the way, the top layer of the heating floor often used soft carpets on the surface, but this turned out to be a good hotbed such as fungi, and easily became a source of generation.

For this reason, the demand for sticking a wooden board on the top layer has arisen and it has come into practical use.However, floors with a wood board are generally severely cooled in winter, and a heating panel is interposed under the wooden board. Such a wooden heating floor resonated well with the floor impact noise, and thus had poor sound insulation performance downstairs.

That is, the impact applied to the wooden board (c) installed on the heating panel (A) propagates through the heating panel (A) and the waste board (a) through the solid and hardly attenuates through the joist (b). Since it propagates to the floor base (11), it is impossible to prevent impact noise downstairs.

If a buffer board (fiber board, foam synthetic resin board, etc.) is inserted between the wooden board (c) and the heating panel (A) in order to prevent such a shock, these materials have heat insulating properties. So the heating will not work.

The conventional method shown in FIG. 2 shows a direct bonding method, in which a plywood discarded plate (a) and a heating panel (A) are placed on a floor base (11).
And carpets, carpets, wooden boards (c), etc. are sequentially laid thereon.

In this case, the shock noise can be reduced to some extent by inserting a buffer plate between the discarding plate (a) and the floor base (11), but this still does not improve the adverse effect of the noise downstairs ( L-60 or higher: Sound insulation grade specified by JISA 1418 Value at a concrete floor thickness of 150 mm).

Then, when the buffer plate is inserted, the discard plate (a) and the floor base (11) are not directly attached, so that the entire panel is easily warped by the heat of the heating panel (A). Get out. This will also cause floor noise in the future.

As described above, since the conventional heating floor requires the heating panel (A) to be firmly fixed, the disposal plate (a) is always laid and nailed. Laying a buffer plate for the purpose of vibration isolation is difficult because the heating panel (A) is not firmly fixed and becomes unstable. If a buffer plate is laid under the discarding plate (a) to improve the sound insulation performance even a little, the discarding plate (a) is not fixed to the floor base, and the discarding plate (a) is heated by the heat of heating. The floor warps and the floor rises partially, causing floor noise and heat source failure.

Further, when the discarded plate (a) is directly fixed to the floor base (11) by nailing or the like, since the impact vibration of the upper part is transmitted directly through the nail, the noise generated on the downstairs becomes extremely large (sound insulation grade L-65). ).

Even if a buffer plate is inserted under the discarding plate (a) as described above, the discarding plate (a) is usually 910 x 1820 mm, so as to take a risk of warping and mitigate any noise. Since a large-sized plate is used, the impact vibration from the top spreads over the entire surface of the disc (a), the effect of preventing noise does not increase so much, and the sound insulation class is only L-60.

[Problem to be solved by the invention] In order to prevent the impact applied to the top of the wooden floor, use thick and heavy materials for the flooring,
A buffer plate having a spring constant appropriate for the floor material must be laid under the lower layer, and fixing means (for example, bolting, nailing, etc.) that easily transmit an impact directly to the floor base must be avoided.

In the heating floor using wood material as the top layer, the heating panel is laid under the wooden floor plate, but even if you try to insert a buffer plate between them for soundproofing, the buffer plate generally has good heat insulation properties The heat does not transfer to the upper wooden floorboards, so that the cushioning plates cannot be inserted between them.

On the other hand, a hot water panel used as one of the heating panels is a semi-rigid foam synthetic resin material plate, in which a synthetic resin pipe through which warm water passes is buried. If the material of the plate is made too soft, it tends to be deformed, which is likely to cause a failure such as water leakage. If a buffer plate is placed under the hot water panel, the hot water panel moves up and down, which also causes a failure. If you put a base board that will be a hard discard board under the hot water panel, it will not be soft and will be a strong floor, but it will be a wooden floor board from the top, then a hot water pipe made of semi-rigid foam resin, the bottom layer All layers are made of a hard material such as a hard base plate. In this case, the upper impact is easily transmitted to the lower layer. This is the same even when an electric heating panel is used instead of the hot water panel.

When the buffer is not inserted in this way, the sound insulation grade is L-
65.

By laying a buffer plate under the base plate, it is possible to reduce the impact sound to some extent without affecting the hot water panel. However, since the impact sound spreads over the entire base plate, the degree of reduction is limited to the sound insulation class L. At -60, this is still insufficient for soundproofing. In addition, when the base plate is a single plate and is not fixed to the floor base, it tends to warp due to heat from above, which causes floor noise.

It is an object of the present invention to provide a wooden heating floor having an improved floor impact sound preventing performance which improves the above points.

That is, conventional wooden floors are extremely cold, and if a heating panel is interposed on the lower surface of the wooden floor to form a heating floor, the wooden heating floor resonates well with the floor impact sound, and therefore the sound insulation performance downstairs is reduced. Although it was bad, the present invention improves this and provides a wooden heating floor with excellent floor impact noise prevention performance.

[Means for Solving the Problems] On a floor base (11) of a building, a sound insulating base plate (B) comprising a buffer base plate (1) and a slit base plate (3) cut out from a slit (4). And a soft sheet (5), a heating panel (A '), and a wooden floor decorative board (6) are sequentially laid on the slit base board (3). The above-mentioned wooden sound-insulating heating floor is characterized in that the wooden sound-insulating heating floor and the buffer plate (1) are constituted by small pieces or streaks of cushioning material.

[Operation] The wooden sound-insulated heating floor of the present invention has an effect of shock and vibration insulation by having a base plate with slits cut therein, so that the impact vibration does not spread to the whole base plate and the base plate has slits. Since the base plate is divided into small pieces by cutting, the warpage of the slit base plate due to the heat of the heating panel is reduced, so that the floor rises from the floor base even if the buffer plate is inserted in the bottom layer Can be prevented. As described above, the slit base plate is divided into small sections by slit cutting, so that it is possible to minimize the expansion of impact vibration from above, and the slit reduces the rigidity of this slit base plate, The buffer effect of the lowermost buffer mat can be improved.

There is a heating panel between the slit base plate and the wooden floor decorative panel, and a soft sheet is interposed on the lower surface.Therefore, the slit base panel and the wooden floor decorative panel do not directly and acoustically integrate, and the function of the slit is reduced. Hold.

In the small section of the slit base plate sandwiched between the soft sheet and the buffer plate, free vibration is further excited, and the impact vibration transmitted from the upper part is consumed as kinetic energy, and the impact vibration is further absorbed.

[Example] In the reference diagram of FIG. 3, the impact vibration applied to the wooden floor decorative panel (6) propagates to the lower heating panel (A '). A hot water panel used as one of the heating panels (A ') has a pipe (p) through which hot water passes,
It is made of a heat-insulating foam synthetic resin material. Since the heating panel (A ') receives a load from above at all times, a relatively semi-rigid material is used. The impact vibration transmitted to the heating panel (A ') is transmitted to the slit base plate (3) almost without being weakened due to the semi-rigid material.

5a and 5b show an embodiment of the present invention.

At this time, the slit base plate (3) is moved in one direction only, as shown in FIG. 4 (a), or in two directions (vertical / horizontal direction or oblique direction) as shown in FIGS. 4 (b) and 4 (c). Since the slit (4) is cut at the intersection, the impact vibration transmitted from above is prevented from expanding here. When the slit (4) is formed as shown in FIGS. 4 (b) and 4 (c), the rigidity of the plate is lower than that of the slit base plate (3) of FIG. 4 (a). Further, since the soft sheet (5) is provided on the slit base plate (3) and the cushioning plate (1) is provided on the lowermost layer, each single piece of the slit base plate (3) is easily vibrated, and the Can absorb shock.

Then, as shown in FIGS. 5a and 5b,
Heating panel (A), soft sheet (5), slit base plate (3) and buffer plate (1) on the lower surface of the wooden floor decorative plate (6)
A predetermined shape such as 910mm x 910mm or 910m
mx 1820mm.

This is laid smoothly on a floor base (11) [usually a concrete floor base, but may be a wooden floor base], and fixed to the floor base (11) with an adhesive.

When using nails, do not damage the heat source and use screw nails or barbed nails to avoid loosening later. The tip of the nail should be stopped at the slit base plate (3) so as not to reach the floor base (11). In order to prevent the wooden sound-insulated heating floor of the present invention from directly contacting the wall base (9), for example, a damping strip (2) is inserted in advance around the wall. (H) is a baseboard.

5a and 5b, as another example taking into account the dimensions, a plywood having a thickness of 9 to 12 mm is formed on a soft fiber board made of synthetic resin having a thickness of 5 mm as a buffer plate (1). It is attached as a base plate (3), and slits (4) having a width of 1 to 2 mm are cut in a width of 100 mm each in the vertical and horizontal directions, and a soft sheet (5) of 0.5 to 1 mm is arranged thereon. . Heating panel (A ') is 1-12mm thick, wood floor decorative panel on top layer (6)
Has a thickness of 5 to 20 mm.

The floor base (11) is made of concrete and has a thickness of 150 mm.
The above-mentioned sound insulation base plate (B) is laid thereon and fixed with an adhesive. Next, a heating panel (A ') [thickness 1 to 12 mm] is attached while connecting pipes, and is attached to the entire room. In addition, beneath the wall base (9), a 96 mm glass wool with a thickness of 10 mm is wrapped around the periphery as a vibration-damping strip (2) so that impact vibrations do not propagate to the wall base (9). It is effective.

The lowermost buffer plate (1) is a soft fiber board, a foamed synthetic resin board, a foamed synthetic resin chip board, a soft (foamed) rubber board, a soft (foamed) rubber chip board, a synthetic resin monofilament three-dimensional mesh, or the like. Combinations of more than one species are possible.

The thus-obtained wooden sound-insulated heating floor of the present invention had a sound insulation rating of L-55.

 The slit may be penetrating or semi-penetrating.

In the configuration of FIGS. 6a to 6d, a slit (4a) formed by cutting a slit (4) into a semi-through slit (1a) or a strip (1b) of a synthetic resin chip plate or a rubber chip plate as a buffer plate. A large number were used in parallel on the lower surface of the base plate (3).

By providing the slit base plate (3) with the slit (4) in this manner, the rigidity of the slit base plate (3) is reduced, and the impact vibration propagated from above is expanded to the slit base plate (3). To prevent.

As described above, a wooden floor decorative board (6) is attached to the slit base plate (3) for both nailing and bonding. However, if the slit base plate (3) is thinner than the above-described dimensions, the wooden base material is used for nailing. The floor panel (6) dances and nails are difficult to hit. When it is permissible to apply the wooden floor decorative board (6) only with the adhesive, the thickness of the slit base plate (3) can be as thin as about 2.5 mm to about 9 mm. Can be installed without dancing, and the sound insulation performance is further improved.

As the type of the heating panel (A '), the hot water panel uses hot water as a heat source, but an electric heating panel using electric resistance can also be applied.

As an example, the electric heating panel has a metal sheet adhered to one or both sides, a heater warms the metal sheet, and radiant heat from the heater heats the uppermost wooden floor decorative panel (6).

Since the slit base plate (3) is divided by the slits (4) and the size of each plate is reduced, the slit base plate (3) warps even if it is affected by some heat of the heating panel (A '). There is no harmful deformation that can cause peeling or gaps and cause floor noise.

That is, conventionally, as such a base plate material,
The size of 910 x 1820mm is used, so the warping force is quite large, but the semi-penetrating slit (4)
The warping force is considerably reduced only by putting in a pitch of 50 to 100 mm, and there is almost no risk of warping when a through slit is formed and the base material is separated by small pieces.

FIGS. 5a and 5b show a case in which a soft sheet (5) is interposed in an upper layer of a slit base plate (3) in which a slit (4) used as a sound insulating base plate (B) is cut. is there.

All are 1mm thick cloths as soft sheet (5) (use of woven or non-woven fabric containing air in fiber)
After using a latex rubber sheet and pasting it to the slit base plate (3) in advance, the slit (4 ') is cut. However, when the soft sheet (5) is to be pasted, there is no need to intentionally cut the slit (4 ').

The sound insulation grade of the wooden heating floor thus obtained is L-
It was 50.

As the soft sheet (5), a foamed synthetic resin sheet, a soft (foamed) rubber sheet (0.5 to 2.0 mm in thickness) and the like are also used.

Also, as shown in FIGS. 6c and 6d, on the lower surface of the semi-through slit base plate [9 mm thick], as a buffer plate, a thickness of 1 to 5 mm shown in FIG. A soft sheet (5) is placed on a slit base plate (3) on which small pieces (1a) or striped strips (1b) of a soft rubber chip plate are arranged.
[Thickness 0.5 to 1 mm], in the case where the heating panel (A ') and the wooden floor decorative panel (6) were sequentially mounted, the sound insulation class of the lightweight floor impact sound was L-45.

"Effects of the invention" This invention fixes a sound-insulating base plate consisting of a slit base plate with an adhesive or the like on a buffer plate laid on the floor base of the building, and then soft sheets, heating panels and wooden floors Because of the configuration of the wooden sound-insulating heating floor in which decorative panels are sequentially laid, the impact sound prevention performance is high, and it is possible to use a wooden floor decorative panel using a heating panel.

In particular, the heat insulation and vibration damping of the soft sheet make it difficult for heat to escape to the slit base plate, increasing the thickness of the slit base plate and increasing the pressure resistance of the heating floor. As the thickness can be reduced, the floor surface can be easily warmed up in a short time, improving the thermal efficiency of the heating panel and maintaining the sound insulation performance even when the heating panel is inserted into the floor by vibrating the soft sheet underneath. Can be done.

In addition, due to the soft sheet affixed on the slit base plate, due to the cushioning properties of the soft sheet, irregularities on the back of the heating panel provided on it and irregularities such as seams can be absorbed, and it fits tightly as floor material The performance is improved.

Furthermore, in the past, when a heating panel was used, the impact sound was loud, so carpets were used exclusively as floor finishes. And provide a hygienic environment free of mold.

The material constituting the wooden sound-insulated heating floor of the present invention can be prefabricated and factory-produced in advance, and the construction can be completed with the same number of man-hours and construction time as the conventional heating floor.

In addition, the sound insulation rating in the specification is based on JIS A 1419, Fig. 2
Nominal values in accordance with JIS, all converted to sound insulation grade of concrete floor (thickness: 159 mm), Japan Foundation for Construction Research.
