Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a heated floor structure, and in particular, a rigid heating panel material with a built-in hot water pipe is disposed between a floor base and a floor finishing material. Regarding the heated floor structure.

(Prior Art) The heated floor structure described above does not pollute the air and provides a uniform feeling of heating, so it has recently been widely used as a comfortable, sanitary, and highly safe heating method. .

In order for this heated floor structure to perform the above functions, it is required that the hot water pipes not be damaged by the load applied to the floor finishing material, and that the hot water pipes uniformly heat the floor finishing material. In order to meet these requirements, a heat dissipation plate made of an aluminum-plated steel plate or the like is usually disposed on the surface of the heating panel material in contact with the hot water pipe.

However, when heating floor panel materials such as those described above are laid directly on floor slabs of medium-to-high-rise residences, etc., when a person walks on the floor covering material, the floor impact force applied to the floor covering material is transmitted through the heating panel. In particular, when wood flooring is used as the floor finishing material, the floor impact force applied to the floor finishing material is transmitted to the heating panel material without being mitigated, causing floor impact noise to be heard downstairs. It feels even louder.

However, as shown in Fig. 3, a heating panel material C is placed on a subfloor a made of a concrete floor slab or the like through a rigid heat insulating material such as expanded polystyrene, and the heating panel material C is placed on top of the heating panel material C. A heated floor structure has also been proposed in which a floor finishing material d is laid down, but since the hard insulating material cannot absorb the floor impact force, the floor impact noise transmitted downstairs is not significantly reduced.

(Problems to be Solved by the Invention) Therefore, the present inventors interposed a cushioning material between the heating panel material and the floor base, and the cushioning material absorbs the floor impact force,
This was designed to reduce the floor impact noise transmitted downstairs.

However, when a cushioning material is interposed between the heating panel material and the flooring, only the cushioning material directly under the heating panel material to which the floor impact force was transmitted compresses or restores, so the joints between the heating panel materials The joints of the hot water pipes became loose or damaged, making it easy for hot water to leak, and the sides of the heating panels rubbed against each other, causing squeaks.

In view of the above, an object of the present invention is to reduce floor impact noise downstairs without causing damage to joints of hot water pipes or squeaks between heating panel members.

(Means for Solving the Problem) In order to achieve the above object, the invention of claim (1) provides a structure in which a rigid panel material is integrally connected on a cushioning material layer, and a heating device is provided on the rigid panel material. By laying the panel material, when a floor impact force is applied to the floor finishing material, the heating panel material as a whole is uniformly moved up and down.

Specifically, the solution taken by the invention of claim (1) is that a plurality of cushioning support members, each of which has board materials such as plywood laminated on top of a cushioning material layer, are laid on a subfloor made of a concrete floor slab or the like. , a rigid panel material having dimensions larger than the cushioning support member is integrated on the upper surface of the cushioning support member so as to connect the plate materials, and a rigid panel material having a built-in hot water pipe is mounted on the rigid panel material. A heating panel material is laid down, and a floor finishing material is laid on top of the heating panel material.

In addition, the invention of claim (2) provides a structure in which a board material such as plywood and a cushioning material layer in the cushioning support member are combined in order to improve the sound insulation properties of the cushioning support member or to impart rigidity to the cushioning support member itself. It is an integrally laminated structure with a damping material layer, a sound insulating material layer, or a reinforcing plate or a combination thereof interposed therebetween.

(Function) According to the configuration of the invention as claimed in claim (1), since the cushioning support member having the cushioning material layer is disposed between the floor base and the rigid panel material, the floor shock applied to the floor finishing material is When the force is transmitted to the cushioning support member through the heating panel material and the rigid panel material, the floor impact force is absorbed by the cushioning material layer of the cushioning support member.

In addition, since the rigid panel material is integrated on the top surface of the cushioning support member so as to connect the boards such as plywood, the impact force transmitted to the heating panel material is temporarily dispersed by the rigid panel material, and the cushioning support member As each rigid panel material vibrates together with the board material while being absorbed by the shock absorbing material layer through the plate material of the member, the shock absorbing material layer of each shock absorbing support member as a whole compresses and restores itself, and therefore the rigidity The heating panel material on the panel material also moves up and down uniformly as a whole, and each heating panel material does not move up and down individually.

According to the configuration of the invention as claimed in claim (2), if a damping material layer or a sound insulating material layer is interposed between the board material such as plywood and the buffer material layer and the layer is integrated, the impact transmitted to the board material such as plywood can be reduced. The vibration energy associated with the force is once attenuated by the damping material layer and the sound insulation material layer, and then absorbed by the cushioning material layer below, so it is possible to reduce the impact noise caused by the vibration of the plate material, and also to integrate them. By doing so, the impact force transmitted to the plate material acts uniformly on the cushioning material layer, and the absorption of impact force is made uniform.

In addition, if a reinforcing plate is interposed between the above-mentioned plate material and the cushioning material layer and the layers are integrated, the rigidity of the upper surface of the cushioning support member will be improved, making the integration with each rigid panel material even stronger. This makes it even more difficult for the heating panel materials to move up and down individually.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIGS. 1 and 2 show a heated floor structure according to an embodiment of the present invention, in which cushioning support members 2 are laid at appropriate intervals on a floor base 1 made of a concrete floor slab or the like.

Note that if a gap is provided between the cushioning support members 2 as described above, main piping for hot water, etc. can be arranged between the cushioning support members 2, but if piping is not required, the cushioning support members 2 can be spaced apart. The support members 2 may be laid against each other.

The cushioning support member 2 includes a cushioning mat 21 as a cushioning material layer.
, a damping mat 22 as a damping material layer arranged on the damping mat 21, and a plate material 23 arranged on the damping mat 22.
2 and the plate material 23 are integrated with adhesive or the like.

As the damping mat 21, an inorganic fiber mat such as glass wool or rock wool, a synthetic fiber mat such as polyester or polypropylene, or a foamed plastic mat such as foamed urethane or foamed polyethylene can be used as appropriate, and as the damping mat 22, a rubber mat can be used. , a mat made of asphalt, a mat made of soft synthetic resin such as vinyl chloride, etc. can be used as appropriate, and the board material 23 may be a board material such as plywood, particle board, wood fiberboard, or wood cement board, and a rigid panel material to be described later. For installation, use nailing, gluing, etc., as appropriate.

In this case, the vibration damping mat 22 is provided to quickly reduce floor vibration caused by floor impact force on the lower surface of the plate material 23 and to prevent floor impact sound from propagating.

Note that instead of the damping mat 22 disposed between the buffer mat 21 and the plate material 23, a sound insulating material made of a metal plate, a high-density resin mat mixed with an inorganic filler, etc., or a resin plate,
A reinforcing plate made of a metal plate, slate, or the like may be provided alone, or a suitable combination of the vibration damping mat 22 and the above sound insulating material and reinforcing plate may be provided. Note that the vibration damping mat 22, sound insulation material, and reinforcing plate are used when the thickness of the floor slab 1 is 15 mm.
If the thickness is 0 mm or less, the sound insulation performance of the floor slab 1 itself is low, so it is preferable to provide it, but in the case of a floor slab 1 with a thickness exceeding 150 mm, it is not necessarily necessary to provide it.

A rigid panel material 3 having a larger dimension than the cushioning support members 2 is placed on the upper surface of the adjacent cushioning support members 2 in a state spanning the plurality of cushioning support members 2, The rigid panel 3 is integrated with the plate material 23 of the cushioning support member 2 by a needle member 4 such as a screw nail alone or by a combination of the needle member 4 and an adhesive. Thereby, the rigid panel material 3 connects the plate materials 23 of the cushioning support member 2 to each other.

As the rigid panel material 3, plywood, particle board,
A wood board such as a wood cement board, a metal molded panel, or the like can be used.

A rigid heating panel material 5 is laid on the rigid panel material 3, and the heating panel material 5 is integrated with the rigid panel 3 by screw nails, tapping screws, or the like. The heating panel material 5 includes a heat dissipation plate 51 made of, for example, an aluminum-plated steel plate, a back material 52 made of an aluminum-plated steel plate, etc., and a heat dissipation plate 51 and a back material sandwiched between the heat dissipation plate 51 and the back material 52. A core material 53 made of particle board or the like, and a heat transfer plate 5 disposed in grooves provided at appropriate intervals on the upper part of the core material 53.
4 and a hot water pipe 55 that transmits heat to the heat dissipation plate 51 through the heating panel material 5. However, the heating panel material 5 is not limited to the structure described above, and the heating panel material 5 is not limited to the structure described above. A rigid material having a

A floor finishing material 6 is laid on the heating panel material 5, and as the floor finishing material 6, a wooden floor material, a carpet material, etc. can be used as appropriate. In addition, when using a wooden floor material as the floor finishing material 6, in order to prevent it from drying and shrinking due to the heat of the heating panel material 5, it is recommended to apply grooves 61, 61 on the lower surface to prevent warping. preferable.

As described above, since the cushioning support member 2 having the cushioning mat 21 is disposed under the heating panel 6 via the rigid panel 3 that is integrally connected, the floor covering material 6 is Even if a surface impact force is applied and the floor impact force is transmitted to the cushioning support member 2 via the heating panel 5 and the rigid panel 3, the floor impact force is absorbed by the cushioning mat 21 of the cushioning support member 2. Therefore, it is difficult to transmit to the subfloor 1. Therefore, when a floor impact occurs, the floor impact sound transmitted downstairs is reduced.

In addition, since the rigid panel material 3 is integrated with the plate material 23 of the cushioning support member 2 so as to connect the cushioning support members 2, when a floor impact force is applied to the floor finishing material 6, the cushioning The cushioning support member 2 is uniformly compressed and restored as a whole, and only the portion of the cushioning support member 2 to which the floor impact force is applied is not compressed or restored. Therefore, since the adjacent heating panels 5 do not move up and down individually, the joints in the hot water pipes 54 are not loosened or damaged, there is no hot water leakage, and squeaks between the heating panels 5 are not generated.

In addition, as shown in FIG. 2, the joint portion 5 between the heating panels 5
It is preferable to deviate the position of 6 from the position of the joint between the rigid panel members 3, since this makes it difficult for adjacent heating panels 5 to move up and down individually.

Furthermore, if a damping mat 21 or a sound insulating mat is interposed between the buffer mat 21 and the board material 23, the board material 23 can be
Since the vibration energy transmitted to the floor is converted into thermal energy and attenuated by the vibration damping mat 21 and the sound insulation mat, the floor impact sound transmitted to the lower floor is further reduced.

Below, JIS-A-1 conducted to evaluate the present invention
The n1 constant result of the floor impact sound measurement level based on 418 will be explained.

First, as a specific example, a heated floor structure having the same structure as the above example and having the specifications shown below was prepared.

Floor base 1: Concrete floor slab with a thickness of 150 mm Cushioning support member 2: Buffer mat: Glass wool mat with a thickness of 25 mm and a density of 64 kg/m3 Damping mat: 4 mm thick soft vinyl chloride mixed with inorganic filler Mat plate material: 5.5 mm thick plywood Rigid panel material 3: 12 mm thick plywood Heating panel material 5: Heat sink: 0.5 mm thick aluminum plated steel plate Back material: 0.3 mm thick aluminum plated steel plate core Material: 11mm thick particle board hot water pipe =
Pipe floor finishing material 6 with a diameter of 8 mm arranged in two rows: Plywood floor material with a thickness of 8.5 mm Next, as Comparative Example 1, a heated floor structure shown in FIG. 3 and described below was prepared.

Floor base a: Same structure as the specific example Insulating material b: 40 mm thick foamed polystyrene heat insulating material (product name: Nedafoam) Heating panel material C: Same structure as the specific example Floor finishing material d: Same as the specific example In addition, as Comparative Example 2, heating panel materials similar to those in the specific example were placed on the same flooring (concrete floor slab with a thickness of 150 mm) as in the specific example, and wooden joists were placed at intervals of 300 mm. A heating floor structure was prepared by laying the heating floor through the heating floor and laying the same floor finishing material as in the specific example on top of it.

The measurement results of lightweight floor impact sound in the specific example and comparative example 1.2 are as shown in FIG. In other words, the heated floor structure of Comparative Example 2 is L-72 and the floor impact noise is at a level that can be felt, while the heated floor structure of Comparative Example 1 is L-65 and the floor impact noise is at a level that is noticeable. Whereas,
The heated floor structure of Example 1 is such that the floor impact noise associated with the lightweight floor impact noise that occurs when walking on the upper floor in L-48 is at a level that does not bother you, and It was confirmed that the sound insulation performance of the example was extremely superior to that of Comparative Examples 1 and 2.

(Effects of the Invention) As explained above, according to the heating floor structure according to the present invention, a cushioning support member made of a cushioning material layer and laminated board materials such as plywood is laid on the subfloor surface, and the upper surface of the cushioning support member Since the rigid panel material is integrated with the plate material so as to connect the cushioning supporting members, and the heating panel material is laid on top of the rigid panel material, the floor impact force transmitted to the rigid heating panel is reduced. Since the noise is dispersed by the rigid panel material and absorbed by the cushioning material layer of the cushioning support member, the floor impact noise generated on the upper floor is difficult to be transmitted to the lower floor.

In addition, when a floor impact force is applied to the floor finishing material, since the heating panel material is supported by an integrated rigid panel material, each heating panel material moves up and down uniformly as a whole, and each heating panel material Since the panels do not move up and down individually, there is no problem of damage to the joints of the hot water pipes or of squeaks occurring between the heating panels and the dirt floor.

Therefore, according to the invention of claim (1), floor impact noise transmitted downstairs can be reduced without causing hot water leakage or squeak noise.

Further, according to the invention of claim 2, when a damping material layer or a sound insulating material layer is interposed between the board material of the cushioning support member and the buffer material layer and are integrated, vibration absorption of the board material is achieved. In addition to improving sound insulation performance, the integration of the cushioning material layer and board material equalizes the absorption of impact force, further reducing floor impact noise, and the use of reinforcing plates improves the rigidity of the cushioning support member. Since the joint part of the hot water pipe is improved, it is possible to further prevent damage and squeaks from occurring at the joint part of the hot water pipe.
