Description

Description: TECHNICAL FIELD The present invention relates to a heating floor structure in which a heating panel material containing an electric heating element is laid on a floor substrate.

(Prior Art) Since the above heating floor structure can obtain a uniform heating feeling without polluting the air, it is recently being widely used as a comfortable, hygienic, and highly safe heating means. .

In this heating floor structure, as shown in FIG. 4, a relay cord c for power supply for connecting the electric heating element built in the heating panel material a to the relay b connected to the power supply, Since it is necessary to dispose the electrical wiring including the sensor relay cord e for connecting the temperature sensor built in the heating panel material a to the controller d on the floor base f formed of the concrete floor slab or the like, the floor base An underfloor space is provided by arranging a large pull g and a joist h on top of f, and the above electrical wiring is laid in the underfloor space.

(Problems to be Solved by the Invention) However, when the large pull g and the joists h are arranged on the floor base f made of a concrete floor slab as described above, it occurs when a person walks on the floor finishing material. Floor impact is large
In addition to being easily transmitted to the underfloor f through the floor underfloor space, a horizontal continuous underfloor space is formed between the grabs g, so that floor impact sound easily spreads in the underfloor space in the horizontal direction. There was a problem that the floor impact sound that was generated was noisy downstairs.

The present invention has been made in view of the above problems, and elastically and stably supports a heating panel material in a floor structure in which a heating panel including an electric heating element is installed on a floor substrate. The purpose is to reduce the floor impact sound in the downstairs.

(Means for Solving the Problems) In order to achieve the above object, the present invention is to integrally connect a cushioning material layer with a rigid panel material, and to lay a heating panel material on the rigid panel material. When a floor impact force is applied, the heating panel material is moved up and down uniformly as a whole.

Specifically, the solution means taken by the present invention is to lay a plurality of cushioning support members formed by laminating a cushioning material layer on the lower surface of a plate material such as plywood on a floor base made of a concrete floor slab or the like,
On the cushioning support member, a rigid panel material having a size larger than that of the cushioning support member and for connecting and integrating the plate materials is laid, and an electric heating element is built on the rigid panel material. The heating panel material is laid in a state of being electrically connected.

(Operation) With the above configuration, since the cushioning support member having the cushioning material layer is disposed between the floor base and the rigid panel material, the floor impact force is buffered through the heating panel material and the rigid panel material. When transmitted to the flexible support member, the floor impact force is absorbed by the cushioning material layer of the cushioning support member. In this case, since a rigid panel material having a size larger than that of the cushioning support member is laid on the cushioning support member, the floor impact force transmitted to the heating panel material is dispersed by the rigid panel material, It is absorbed by the cushioning material layer through the plate material of the cushioning support member.

In addition, since a rigid panel material that connects the plate materials to each other and integrates them is laid on the cushioning support member, when the floor impact force is applied, each integrated plate material is uniform with the rigid panel material. Since the cushioning material layer of each cushioning support member is compressed or restored as a whole, the heating panel material on the rigid panel material moves up and down uniformly as a whole, and each heating panel material is individually It does not move up and down.

Furthermore, since the various electric wires are not pulled by the vibration of the heating panel material, the damage to the electric wires is reduced, and the relay cord for the power supply drawn on the rigid panel and the panel lead wire provided on the heating panel material are reduced. The joint between the electric wirings such as the joint and the like also moves up and down uniformly on the rigid panel, so that the joint is not easily damaged.

(Example) Hereinafter, the Example of this invention is described based on drawing.

1 and 2 show a heating floor structure according to an embodiment of the present invention, in which a cushioning support member 12 is laid at appropriate intervals on a floor base 10 made of a concrete floor slab or the like.

The cushioning support member 12 has a cushioning mat 14 as a cushioning material layer.
And a damping mat 16 arranged on the cushioning mat 14,
It is composed of a plate material 18 arranged on the vibration damping mat 16, and the cushioning mat 14, the vibration damping mat 16 and the plate material 18 are integrated by an adhesive or the like.

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 appropriately used as the cushioning mat 14, and a rubber mat is used as the vibration damping mat 16. , An asphalt mat, or a soft synthetic resin mat such as vinyl chloride can be used as appropriate, and the plate material 18 is a plate material such as plywood, particle board, wood fiber board or wood cement board, which is a rigid panel material described later. Those that can be attached by nailing, bonding, or the like can be used as appropriate. In this case, the damping mat
Reference numeral 16 is provided to promptly reduce floor vibration caused by floor impact force on the lower surface of the plate member 18 and prevent propagation of floor impact sound.

In addition, the damping mat disposed between the cushioning mat 14 and the plate material 18
Instead of 16, a sound insulating material made of a high density resin mat mixed with a metal plate or an inorganic filler, or a resin plate, a metal plate, a reinforcing plate made of a slate or the like may be provided alone. A combination of the vibration damping mat 16 and the sound insulating material and the reinforcing plate may be arranged. The damping mat 16,
It is preferable to provide the sound insulating material and the reinforcing plate because the sound insulation performance of the floor base 10 itself is low when the thickness of the floor base 10 is 150 mm or less, but in the case of the floor base 10 having a thickness exceeding 150 mm. Need not necessarily be provided.

The cushioning support member 12 is provided on the floor base 10 near the wall.
An appropriate joist 20 is laid at appropriate intervals, and an elastic body 21 made of rubber, soft synthetic resin, or the like for absorbing vibration is disposed on the lower side and the wall surface side of the joist 20. ing.

The upper surfaces of the adjacent cushioning support members 12 and the cushioning support members
A rigid panel material 22 having a size larger than that of the cushioning support member 12 is placed on the upper surfaces of the cushioning support member 12 and the joist 20 so as to straddle a plurality of cushioning support members 12.
Reference numeral 22 denotes a shock-absorbing support member 12 by a nail member 24 such as a screw nail or by a combination of the nail member 24 and an adhesive.
It is integrated with the plate material 18 of. As a result, the rigid panel member 22 connects the plate members 18 of the cushioning support member 12 and integrates them.

As the rigid panel material 22, plywood, particle board,
A wood board such as a wood cement board or a metal molded panel can be used.

A heating panel material 26 is laid on the rigid panel material 22 by bonding or the like.

As the heating panel material 26, a core material 28 made of plywood or the like, a heat insulating material 30 made of polyurethane foam or a glass fiber mat disposed in a hollow portion formed in the core material 28, and the heat insulating material 30 It is possible to use the one composed of the electric heating element 32 laid on the top.

On both sides of the core material 28 are provided actual processing parts 28a composed of male and female fruits used for joining the heating panel materials 26 to each other, and on the upper surface of the core material 28 is a wood decorative material 34. It is attached together.

As the electric heating element 32, a sheet heating element or a heater wire that directly generates heat when energized, or a heat storage element that is heated by energization and can store thermal energy can be used alone or in combination as appropriate. The electric heating element 32 is connected to a relay 36 attached to a wall member 35 and electrically connected to a power source through a relay cord 38 for the power source. In addition, the electric heating element of the adjacent heating panel material 26
The two 32 are electrically connected to each other through a power supply cord 40. In this case, the relay cord 38 for the power source is the rigid panel material 22.
The power supply cords 40 are housed in the notches provided in the back surface of the core material 28 in the grooves provided in the.

For a sensor connected to a temperature sensor (not shown) that is arranged in the core material 28 of the heating panel material 26 near the relay 36 in the wall material 35 and detects the internal temperature of the heating panel material 26. A relay cord 42 and a controller 46 provided with a signal cord 44 for controlling energization of the relay are attached. In this case, the sensor relay cord 42 is housed in the groove provided in the rigid panel member 22 like the power source relay cord 38, and the signal cord 44 is housed on the back surface side of the wall member 35.

Instead of the above embodiment, the power relay cord 28 and the sensor relay cord 42 are laid between the cushioning support members 12 below the rigid panel 22, and a through hole is provided in the rigid panel member 22. The cord lead-out hole (not shown) opened by the above may be penetrated and connected to the electric heating element 32 and the temperature sensor, respectively.

Further, in place of the above-mentioned embodiment, as the heating panel material 26, one having no wood floor finishing material 34 pasted on its surface is used.
A floor finishing material such as a carpet or a wooden floor material may be laid on the heating panel material 26.

As described above, since the cushioning support member 12 having the cushioning mat 14 is disposed below the heating panel material 26 via the integrated rigid panel material 22, the floor is placed on the floor finishing material. Even if an impact force is applied and the floor impact force is transmitted to the cushioning support member 12 via the heating panel material 26 and the rigid panel material 22, the floor impact force is absorbed by the cushioning mat 14 of the cushioning support member 12. It is hard to reach floor base 10. Therefore, the floor impact sound transmitted downstairs during floor impact is reduced.

Further, since the rigid panel material 22 connects and integrates the plate materials 18 of the cushioning support member 12, when the floor impact force is applied on the floor finishing material, the cushioning support member 12 becomes uniform as a whole. It is compressed or restored, and only the cushioning support member 12 at the site where the floor impact force is applied is not compressed or restored. For this reason, since the adjacent heating panel members 26 do not individually move up and down, the electric wiring such as the power supply cord 40 disposed between the heating panel members 26 is not damaged, and the squeak noise between the heating panel members 26 is not generated. Does not occur.

Further, since the cushioning support member 12 is laid in the underfloor space, the reverberation of the floor impact sound is reduced, and the noise downstairs due to the reverberation is also reduced.

Hereinafter, the measurement results of the floor impact sound measurement level according to JIS-A-1418 performed for evaluating the present invention will be described.

First, as a specific example, a heating floor structure having the same structure as that of the above embodiment and having the following specifications was prepared.

Floor base 10: Concrete floor slab with a thickness of 150 mm Buffer support member 12: Buffer mat: 25 mm thick, glass wool mat with a density of 64 kg / m ³ Damping mat: 4 mm thick soft vinyl chloride mixed with inorganic filler Mat: Board material: 5.5 mm thick plywood Rigid panel material 22: 12 mm thick plywood Heating panel material 26: Core material: 15 mm thick plywood Insulation material: Polyurethane foam Electric heating element: Heater wire Next, comparative example As a result, a heating floor structure shown in FIG. 4 and described below was prepared. That is, wood joists h are laid at intervals of 300 mm on a floor base f (concrete floor slab having a thickness of 150 mm) similar to that of the specific example with a large pull g, and a glass wool mat is provided between the wood joists h. A heating floor structure was prepared in which a heat insulating material i was arranged and a heating panel material a similar to the specific example was laid on the wooden joist h.

The measurement results of the lightweight floor impact sound in the specific example and the comparative example are as shown in FIG. That is, while the heating floor structure of the comparative example was at a level where the floor impact sound was annoying at L-62, the heating floor structure of the specific example was L-51 when walking on the floor of the upper floor. It is at a level where the floor impact sound due to the lightweight floor impact force generated in the above is not a concern, and the concrete example has extremely excellent sound insulation performance compared to the comparative example for the lightweight floor impact sound. I was able to confirm that

(Effects of the Invention) As described above, according to the heating floor structure of the present invention, the cushioning support member in which the cushioning material layer and the plate material such as plywood are laminated is laid on the floor substrate, and the cushioning support member is provided on the cushioning support member. Since a rigid panel material having a size larger than that of the cushioning support member is laid, and the heating panel material is laid on the rigid panel material, the floor impact force transmitted to the heating panel material is dispersed by the rigid panel material. After being made to move, since it is absorbed by the cushioning material layer of the cushioning support member, the floor impact sound generated on the upper floor is difficult to be transmitted to the lower floor.

In addition, since a rigid panel material that connects the plate materials to each other and integrates them is laid on the cushioning support member, when the floor impact force is applied, each integrated plate material is uniform with the rigid panel material. Vibration, the heating panel materials also move up and down uniformly as a whole, and each heating panel material does not move up and down individually, so various electrical wiring or joints between various electrical wiring are damaged. There is no problem that the heating panel materials generate bleeding noise between the heating panel materials.

Therefore, according to the present invention, it is possible to reduce the floor impact sound transmitted to the downstairs without damaging the electrical wiring, damaging the joint portion between the electrical wiring and squeaking noise.
