PURPOSE:To reduce the transmission of floor impact noise downstairs by mounting a rigid panel to be crossed over the upper surfaces of bumping bearing members, to form them integrally to form a plate member, and by laying a heating panel member on the plate member. CONSTITUTION:On a floor bed 10, bumping bearing members 12 are laid at proper intervals. The bumping bearing members 12 are formed with oscillation controlling mats 16 to be arranged on bumping mats 14, and plate members 18 to be arranged on the mats 16, and to be crossed over the upper surfaces of the bumping bearing members 12 adjacent to each other, rigid panels 22 are mounted on, and they are integrally formed to form the plate members 18, and on the plate members, heating panel members 26 are laid. Then, even if a floor impact force is worked, the force is absorbed into the impact mats 14 of the bumping bearing members 12 and is hardly transmitted to the floor bed, and the reverberation of impact noise is diminished. As a result, the transmission of the impact noise downstairs at the time of floor impact can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heated floor structure in which a heating panel material containing an electric heating element is laid on a subfloor surface.

(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 this heating floor structure, as shown in FIG. 4, a power supply relay cord C for connecting an electric heating element built into the heating panel material a to a relay b connected to the power supply, Electrical wiring consisting of a sensor relay cord e for connecting the temperature sensor built into the heating panel material a to the controller d must be installed on the flooring f made of concrete floor slabs, etc. An under-floor space is provided by arranging a large g and a thick joist above f, and the above-mentioned electrical wiring is laid in the under-floor space.

(Problem to be Solved by the Invention) However, as described above, when the large pull g and joist thickness are placed on the floor base f made of a concrete floor slab, problems occur when a person walks on the floor finishing material. The floor impact force is large
Not only is it easy to transmit to the subfloor f through There was a problem in that the floor impact sound that occurred was felt to be noisy downstairs.

The present invention has been made in view of the above-mentioned problems, and is an object of the present invention to elastically and stably support a heating panel in a floor structure in which a heating panel with a built-in electric heating element is installed on the subfloor. The purpose is to reduce floor impact noise downstairs.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a structure in which the cushioning material layer is integrally connected with a rigid panel material, and a heating panel material is laid on the rigid panel material. When a floor impact force is applied, the entire heating panel material is moved up and down uniformly.

Specifically, the solution taken by the present invention is that a plurality of cushioning supporting members are laid on a subfloor made of a concrete floor slab or the like, and are made by laminating a layer of cushioning material on the lower surface of a board such as plywood.
A rigid panel material having dimensions larger than the cushioning support member and connecting and integrating the plate materials is laid on the cushioning support member, and an electric heating element is built in on the rigid panel material. The heating panel material is installed in an electrically connected state.

(Function) 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 impact force on the floor is transmitted through the heating panel material and the rigid panel material. When transmitted to the cushioning 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 dimensions larger than the cushioning support member is laid on top of the cushioning support member, the floor impact force transmitted to the heating panel material is dispersed by the rigid panel material. , is absorbed by the cushioning material layer through the plate material of the cushioning support member.

In addition, a rigid panel material that connects and integrates the boards is laid on top of the cushioning support member, so when a floor impact force is applied, each of the integrated boards will come together with the rigid panel material. As the cushioning material layer of each cushioning support member is compressed and restored as a whole, the heating panel material on the rigid panel material also moves up and down uniformly as a whole, and each heating panel material They do not move up and down individually.

In addition, damage to the electrical wiring is reduced because the various electrical wirings are not pulled due to the vibration of the heating panel material, and the power supply relay cord pulled out on the rigid panel and the panel lead wire provided on the heating panel material are Since the joints between electrical wirings, such as the joints with the electric wires, also move up and down uniformly on the rigid panel, the joints are also difficult to move.

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

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

The cushioning support member 12 includes a cushioning mat 1 as a cushioning material layer.
4, and a damping mat 1 placed on the buffer mat 14.
6, and a board 18 placed on the damping mat 16.
are integrated with adhesive or the like.

As the buffer mat 14, 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 vibration damping mat 16, a rubber mat can be used. , a mat made of asphalt, or a mat made of soft synthetic resin such as vinyl chloride, etc. can be used as appropriate, and the board material 18 may be a board material such as plywood, particle board, wood fiber board, or wood cement board, and rigid panel material described later. For installation, use nailing, gluing, etc., as appropriate.

In this case, the vibration damping mat 16 is provided to quickly reduce floor vibration caused by floor impact force on the lower surface of the board 8 and prevent floor impact noise from propagating.

Note that instead of the distribution mat 16 disposed between the buffer mat 14 and the plate material 18, 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, etc. may be provided alone, or an appropriate combination of the vibration damping mat 16 and the above-mentioned sound insulating material and reinforcing plate may be provided. Note that the vibration damping mat 16, sound insulation material, and reinforcing plate are used when the thickness of the floor base 10 is 15 mm.
If the thickness is 0 mm or less, the sound insulation performance of the subfloor 10 itself is low, so it is preferable to provide it, but in the case of the subfloor 10 with a thickness exceeding 150 mm, it is not necessarily necessary to provide it.

A wall joist 20 is laid on the flooring base 10 at an appropriate distance from the cushioning support member 12, and the bottom side and wall side of the floor joist 20 are coated with rubber, soft synthetic resin, etc. An elastic body 21 is provided to absorb vibrations.

The cushioning support members 12 are provided on the upper surfaces of adjacent cushioning support members 12 and on the upper surfaces of the cushioning support members 12 and the border joists 20.
A rigid panel material 22 having a larger dimension is placed astride a plurality of cushioning support members 12, and the rigid panel material 22 has a needle member 24 such as a screw nail.
It is integrated into the plate material 18 of the cushioning support member 12 by the needle member 24 alone or by the combination of the needle member 24 and an adhesive.

Thereby, the rigid panel material 22 connects and integrates the plate materials 18 of the cushioning support member 12.

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

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

The heating panel material 26 includes a core material 28 made of plywood or the like, and a heat insulating material 3 made of polyurethane foam, glass fiber mat, etc. arranged in a hollow part formed in the core material 28.
0 and an electric heating element 32 laid on the heat insulating material 30.
It is possible to use the following.

On both sides of the core material 28, there are provided real processed parts 28a made of male and female parts used for joining the heating panel materials 26 together, and on the upper surface of the core material 28, a wood decorative finishing material 34 is provided. It is glued together.

As the electric heating element 32, a sheet heating element or heater wire that generates heat directly when energized, a heat storage element that can be heated by energization and store thermal energy, etc. can be used alone or in combination as appropriate. The electric heating element 32 is connected via a power relay cord 38 to a relay 36 attached to a wall material 35 and electrically connected to a power source. Further, the electric heating elements 32 of adjacent heating panel members 26 are electrically connected to each other through a power supply cord 4o. In this case, power relay cord 3
8 is housed in a groove provided in the rigid panel 22, and the power supply cord 40 is housed in a notched recess provided on the back surface of the core material 28.

In the vicinity of the relay 36 in the wall material 35, there is a sensor for a sensor connected to a temperature sensor (not shown) that is disposed within the core material 28 of the heating panel material 26 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
Similarly to the power relay cord 38, the signal cord 44 is housed in a groove provided in the rigid panel 22, and the signal cord 44 is housed on the back side of the wall material 35.

Note that instead of the above embodiment, the power supply relay cord 28 and the sensor relay cord 42 are laid between the cushioning support members 12 on the lower side of the rigid panel 22, and through holes are provided in the rigid panel material 22. Alternatively, the cord may be passed through an opened cord pull-out hole (not shown) and connected to the electric heating element 32 and the temperature sensor, respectively.

Moreover, instead of the above embodiment, as the heating panel material 26,
A floor finishing material such as a carpet or a wooden flooring material may be laid on top of the heating panel material 26 by using a panel to which the wooden floor finishing material 34 is not attached.

As described above, since the cushioning support member 12 having the cushioning mat 14 is disposed under the heating panel material 26 via the embodied rigid panel material 22, the floor covering material is placed on the floor finishing material. 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 material 26 and the rigid panel material 22, the floor impact force is transferred to the cushioning mat 1 of the cushioning support member 12.
4, so it is difficult to be transmitted to the subfloor 10.

For this reason, the floor impact noise transmitted downstairs at the time of floor impact is reduced.

Further, the rigid panel material 22 is the plate material 1 of the cushioning support member 12.
8 are connected and integrated, so when a floor impact force is applied to the floor finishing material, the cushioning support part 112 uniformly compresses and restores itself as a whole, thereby reducing the impact on the floor. Only the portion of the cushioning support member 12 to which the force is applied will not be compressed or restored. Therefore, since the adjacent heating panel materials 26 do not move up and down individually, electrical wiring such as the power supply cord 40 installed between the heating panel materials 26 will not be damaged, and squeaks between the heating panel materials 26 will not be caused. does not occur.

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

Below, JIS-A-1 conducted to evaluate the present invention
The measurement results of floor impact sound measurement 1 novel by 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 10: 150 mm thick concrete floor slab Cushioning support member 12: Buffer mat: 25 mm thick, glass wool mat with density 64 kg/m3 Vibration 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 2
6: Core material: 15 mm thick plywood Insulating material: Polyurethane foam Electric heating element: Heater wire Next, as a comparative example, a heating floor structure shown in FIG. 4 and described below was prepared. That is, the same flooring f as in the specific example
Wooden joists are laid at 300mm intervals on top of the (150mm thick concrete floor slab) via large wires g, and a heat insulating material i made of glass wool mat is placed between the wood joists. A heating floor structure was prepared by laying heating panel material a similar to that in the specific example on top of joists.

The measurement results of light floor impact sound in the specific example and comparative example are as shown in FIG. In other words, the heated floor structure of the comparative example was L-62 and the floor impact noise was at a level that was noticeable, whereas the heated floor structure of the specific example was L-51 when walking on the floor of the upper floor. The level of the floor impact noise caused by the impact force on the lightweight floor surface that occurs in other areas is at a level that is not noticeable, and the concrete examples have extremely superior sound insulation performance against the lightweight floor impact noises compared to the comparative examples. I was able to confirm that

(Effects of the Invention) As explained above, according to the heating floor structure according to the present invention, a cushioning support member in which a cushioning material layer and plate materials such as plywood are laminated is laid on the underfloor surface, and the cushioning support member is placed on top of the cushioning support member. Since a rigid panel material having larger dimensions than the cushioning support member is laid down and a heating panel material is laid on top of the rigid panel material, the floor impact force transmitted to the heating panel material is absorbed by the rigid panel material. After being dispersed, it is absorbed by the cushioning material layer of the cushioning support member, so floor impact noise generated on the upper floor is difficult to be transmitted to the lower floor.

In addition, a rigid panel material that connects and integrates the boards is laid on top of the cushioning support member, so when a floor impact force is applied, each of the integrated boards will come together with the rigid panel material. As a result, each heating panel material also moves 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 There is no problem of damage or squeaks occurring between the heating panels and the dirt floor.

Therefore, according to the present invention, it is possible to reduce floor impact noise transmitted downstairs without causing damage to electrical wiring, damage to joints between electrical wiring, and generation of squeaks and squeaks.
