Description

【0001】
【発明の属する技術分野】
この発明は、床暖房パネル用積層体および該積層体を裏面に収容した床暖房パネルに関する。
【0002】
【従来の技術】
裏面側にヒーターなどの発熱器材層を収容するための収容凹部を形成した床暖房用パネルの該収容凹部内に、例えば自己温度制御特性を有する面状発熱体(PTCヒーター)などからなる発熱器材層と硬質発泡ウレタンのような断熱層とを積層状態に収容した床暖房パネルは知られている(特開2001−355862号公報など参照)。発熱器材層とウレタン発泡断熱層とを型内ウレタン発泡成形などにより一体に積層成形することも行われる。この形態の床暖房パネルはそれ自体が断熱層を有していることから、根太の上に敷設された捨貼合板などの床下地材の上に、断熱性シートなどの断熱材を敷設することなく、直接敷設していくことができるので、短時間で効率よく床暖房フロアを施工することのできる利点がある。
【0003】
【発明が解決しようとする課題】
上記した発熱器材層と断熱層としての樹脂発泡体層との積層体を型内発泡成形により製造した場合、発泡層の一方の面は発熱器材層により被覆されているが、他方の面は発泡層そのものが露出している。そのために、成形後に脱型して放置しておくと、積層体の一方の面側と他方の面側とで熱収縮の程度に違いが生じ、放置しておく環境によっては、積層体に反りが生じる場合がある。このような反りの生じた製品は、その反り量が基準値を超えた場合に、不良品として廃棄される。
【0004】
脱型後すぐに、積層体にまだ反りの生じない状態で、床暖房用パネル裏面の収容凹部内に挿入し、接着剤により一体化する場合もある。この場合でも、周囲の環境によっては、同じ理由から積層体に反りが生じることがあり、反りに引きずられて床暖房用パネルそのものに反りが発生することが起こり得る。図7は、捨貼合板などの床下地材1の上に敷き詰めた床暖房用パネル2が、当初は平坦であったものが、積層体6の反りが原因となって、経時的に反りが発生してしまった状態を模式的に示している。なお、図7において、3は裏面側に発熱器材層を収容するための収容凹部を形成した床暖房用パネル基材であり、その収容凹部内に、例えば自己温度制御特性を有する面状発熱体(PTCヒーター)などからなる発熱器材層4と硬質発泡ウレタンのような断熱層5とを積層した積層体6が収容されて、床暖房用パネル2が構成されている。このような状態となると、歩行者が歩くときの押圧力により、床面が上下動するようになり、それにより、いわゆる床鳴りが発生する。
【0005】
本発明は上記のような事情に鑑みてなされたものであり、発熱器材層と断熱層としての樹脂発泡体層とを一体に積層成形した積層体に、経時的に反りが生じるのを抑制できるようにし、それにより、該積層体を収容した床暖房用パネルに反りが発生するのを防止して、暖房フロアで床鳴りを発生するのを阻止できるようにした床暖房パネル用積層体、および該積層体を収容した床暖房パネルを提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明による床暖房パネル用積層体は、裏面側に収容凹部が形成された床暖房用パネル基材の前記収容凹部内に収容される床暖房パネル用積層体であって、発熱器材層と断熱層としての樹脂発泡体層と樹脂発泡体層の裏面を覆う被覆層とが、この順で一体に積層成形されていることを特徴とする。
【0007】
この構成の床暖房パネル用積層体は、断熱層である樹脂発泡体層の一方の面は発熱器材層により覆われており、他方の面は被覆層により覆われていて、4周囲を除き、発泡層そのものは露出していない。そのために、発泡層の表裏面での熱収縮割合はほぼ同じ程度となり、熱収縮の差に起因して反りが発生するのを大きく抑制することができる。それにより、経時的に反りが発生して不良品化するのを阻止することができる。
【0008】
前記床暖房パネル用積層体は種々の方法で作ることができるが、製造の容易性や高い断熱性が確保できることなどの理由から、成形型枠内の一方に発熱器材層を配置し他方に被覆層を配置し、その状態でその間に発泡性ウレタン樹脂を注入して発泡させて、一体に積層成形したものであることは、特に好ましい態様である。
【0009】
本発明において、発熱器材層は任意のものでよく、従来のこの種床暖房パネル内に収容して用いられる発熱器材層をすべて用いることができる。例えば、少なくとも均熱層としてのアルミ箔層とPTCヒーターの層を備えており、必要に応じてPTCヒーターの両面をPETフィルムのような樹脂フィルムでさらに覆うようにしたもの、あるいは、少なくとも均熱層としてのアルミ箔層とそこに融着した線ヒーターとからなる層を備えるものなどは、好ましい層構造である。もちろん、いずれの層構造においても、ヒーターへの導電線およびコネクタ類が従来のこの種積層体と同様にして取り付けられる。
【0010】
本発明において、被覆層は樹脂発泡体層の裏面を覆いかつ被覆した樹脂発泡体面の熱挙動を抑制できるものであれば任意であるが、クラフト紙やPETフィルムのような樹脂フィルムなどが好適である。もちろん、一体成形時での発泡性樹脂の発泡成形条件、および表面側に積層一体化する発熱器材層の持つ熱挙動特性などによって、樹脂発泡体の裏面側に積層する被覆層が備えるべき最適な物性値(経時的に反りを生じさせない最適な物性値)は相違するので、状況に応じて、種類や厚みなども含め最適な物性値を持つ被覆層を実験的に選定することが推奨される。
【0011】
本発明は、また、上記のような床暖房パネル用積層体を基材の裏面側に形成した収容凹部内に収容してなる床暖房パネルをも開示する。床暖房パネル用基材は、従来のフローリングで使用されている床材の裏面に前記積層体が収容できるだけの凹部が形成されたものであれば、基本的に使用可能である。もちろん、必要な場合には、配線用の切り欠き、コネクターを収容する空所などが形成される。必須ではないが、合板やMDFのような木質繊維板である基部の表面に突板などの化粧材が貼り付けられることは好ましく、また、基部の周囲には実が形成されることが好ましい。化粧材には好ましくは疑似溝が形成される。
【0012】
【発明の実施の形態】
以下、図面を参照しながら、本発明を実施の形態に基づき説明する。図1は本発明による床暖房パネル用積層体の一例を示す斜視図であり、図2はその一部を分解した状態で示す図である。床暖房パネル用積層体10は、発熱器材層20と、断熱層としての樹脂発泡体層30と、樹脂発泡体層30の裏面を覆う被覆層40とが、この順で一体に積層成形されて構成されている。
【0013】
発熱器材層20は、従来の床暖房における発熱器材層として用いられているものを任意に用いうるが、この例では、均熱層としてのアルミ箔(0.1mm厚程度のもの)21、不織布22、PETフィルム23、PTCヒーター24、PETフィルム25、とをこの順で積層したものを用いている。アルミ箔に線ヒーターを融着した形態のものであってもよい。なお、発熱器材層20には、電気的結線を行うためのオスコネクタ26、メスコネクタ27が適宜の方法により取り付けられる。
【0014】
樹脂発泡体層30は、この例では硬質発泡ウレタンを用いているが、発泡スチロールのようなものであってもよい。被覆層40は、樹脂発泡体層30の裏面を覆いかつ被覆した樹脂発泡体面の熱挙動を抑制できるものであれば任意である。この例では、75g/m程度のクラフト紙を用いているが、PETフィルムのような樹脂フィルムであってもよい。
【0015】
上記した発熱器材層20、樹脂発泡体層30および被覆層40は、適宜の方法により一体に積層されて床暖房パネル用積層体10とされる。好ましくは、図3に示すように、成形型枠7の底面側に発熱器材層20を配置し、蓋8側に被覆層40を配置した状態で、その間に発泡性ウレタン樹脂を注入してウレタン発泡を行い、発泡したウレタン層(樹脂発泡体層30)の表面と裏面に、発熱器材層20と被覆層40とを一体に積層させる。本発明による床暖房パネル用積層体10は、断熱層である樹脂発泡体層30の一方の面は発熱器材層20により覆われており、他方の面は被覆層40により覆われているので、樹脂発泡体層30の表裏面での熱収縮割合はほぼ同じ程度とすることができ、熱収縮の差に起因して床暖房パネル用積層体10に反りが発生するのは実質的に抑制される。発泡スチロールを樹脂発泡体層30として用いる場合には、発熱器材層20と被覆層40とを接着剤により貼り付け一体化するようにしてもよい。
【0016】
本発明による床暖房パネル用積層体10を、図4に示すように、床暖房用パネル基材50の裏面側に形成した収容凹部51内に収容することにより、本発明による床暖房用パネル60が形成される。床暖房用パネル基材50としては、従来のフローリングで使用されているこの種の基材を任意に用いることができる。この例において、平板状のMDFの裏面をくり抜いて前記収容凹部51を形成するとともに、その周囲には、前記オスコネクタ26およびメスコネクタ27を収容するための空所52、53が形成され、また、4周の木口部には実加工54が施されている。床暖房用パネル基材50表面側には突板などの化粧材55が貼り付けられ、そこには疑似溝56が形成されている(図5a参照)。
【0017】
収容凹部51の大きさと深さは、その内部に床暖房パネル用積層体10が隙間のない状態で収容される大きさと深さであり、図4aに示すように、収容凹部51の内部に接着剤Sを塗布した後、接着剤Sが未硬化の状態で、その内部に床暖房パネル用積層体10を挿入し接着剤を硬化させる(図4b)。図5は硬化後の状態(すなわち、本発明による床暖房パネル60)を示しており、図5bの断面図に示すように、床暖房パネル用積層体10は、その裏面が床暖房用パネル基材50の裏面と同じ平面をなすようにして収容凹部51内に収容され、床暖房用パネル基材50と接着剤により一体化している。
【0018】
図6は、上記のようにして形成した床暖房パネル60を、従来と同じようにして、捨貼合板などの床下地材1の上に敷き詰めた状態を示している。床暖房パネル用積層体10に反りが発生するのが抑制されており、結果として、床暖房パネル60に経時的に反りが発生することはないので、図示のように、床下地材1と床暖房パネル60の裏面との間に隙間が生じることはなく、歩行者が歩くときの押圧力により、床鳴りが発生するようなことはない。
【0019】
【発明の効果】
本発明によれば、床暖房パネル用積層体に反りが生じるのが抑制されており、結果として、床暖房パネルに経時的に反りが生じることもない。そのために、床下地材の上に床暖房パネルを直接的に配置してフローリングを施工しても、隙間が発生することはなく、歩行者が歩くときの押圧力により床鳴り現象が起こるのを長期間にわたって、阻止することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor heating panel laminate and a floor heating panel in which the laminate is housed on a back surface.
[0002]
[Prior art]
A heating element made of, for example, a sheet heating element (PTC heater) having a self-temperature control characteristic, is provided in the accommodation recess of the floor heating panel having an accommodation recess for accommodating a heating element layer such as a heater on the back side. A floor heating panel in which layers and a heat insulating layer such as hard foamed urethane are accommodated in a stacked state is known (see Japanese Patent Application Laid-Open No. 2001-355882). The heat generating material layer and the urethane foam heat insulating layer may be integrally laminated and molded by in-mold urethane foam molding. Since the floor heating panel of this form itself has a heat insulating layer, without laying a heat insulating material such as a heat insulating sheet on a floor base material such as a discarded laminate laid on the joist. Since the floor heating floor can be laid directly, there is an advantage that the floor heating floor can be efficiently constructed in a short time.
[0003]
[Problems to be solved by the invention]
When a laminate of the above-described heating device layer and a resin foam layer as a heat insulating layer is manufactured by in-mold foam molding, one surface of the foam layer is covered with the heating device layer, while the other surface is foamed. The layer itself is exposed. Therefore, if the mold is removed from the mold and left to stand, the degree of heat shrinkage will be different between one side and the other side of the laminate, and depending on the environment in which the laminate is left, the laminate may warp. May occur. A product having such a warp is discarded as a defective product when the warp amount exceeds a reference value.
[0004]
Immediately after the mold is released, the laminate may be inserted into the accommodation recess on the back surface of the floor heating panel in a state where warpage has not yet occurred, and integrated with an adhesive. Even in this case, depending on the surrounding environment, the laminate may be warped for the same reason, and the floor heating panel itself may be warped due to the warpage. FIG. 7 shows that the floor heating panel 2 laid on the floor base material 1 such as a laminating plate was initially flat, but warpage occurs over time due to the warpage of the laminate 6. The state which has been done is shown typically. In FIG. 7, reference numeral 3 denotes a floor heating panel base material having a housing recess formed on the back side for housing the heating equipment layer, and a planar heating element having, for example, self-temperature control characteristics in the housing recess. (A PTC heater) or the like, and a laminated body 6 in which a heat-generating material layer 4 made of a material such as a hard urethane foam and a heat-insulating layer 5 are laminated are accommodated, and the floor heating panel 2 is configured. In such a state, the floor surface moves up and down due to the pressing force when the pedestrian walks, thereby causing floor noise.
[0005]
The present invention has been made in view of the above circumstances, and it is possible to suppress the occurrence of warpage over time in a laminate obtained by integrally laminating a heating element layer and a resin foam layer as a heat insulating layer. As a result, the floor heating panel laminate in which the floor heating panel containing the laminate is prevented from warping and the floor floor can be prevented from generating noise on the heating floor, and It is an object of the present invention to provide a floor heating panel containing the laminate.
[0006]
[Means for Solving the Problems]
The floor heating panel laminate according to the present invention is a floor heating panel laminate housed in the housing recess of the floor heating panel base material having a housing recess formed on the back surface side, wherein the heating device material layer and the heat insulating material are insulated. A resin foam layer as a layer and a coating layer covering the back surface of the resin foam layer are integrally laminated and formed in this order.
[0007]
In the floor heating panel laminate of this configuration, one surface of the resin foam layer, which is a heat insulating layer, is covered by a heating material layer, and the other surface is covered by a covering layer, except for 4 surroundings, The foam layer itself is not exposed. Therefore, the heat shrinkage ratio between the front and back surfaces of the foam layer is substantially the same, and the occurrence of warpage due to the difference in heat shrinkage can be greatly suppressed. As a result, it is possible to prevent the occurrence of warpage over time and defective products.
[0008]
The floor heating panel laminate can be made by various methods, but for reasons such as ease of production and high heat insulation, a heating material layer is arranged on one side of the forming mold and covered on the other side. It is a particularly preferred embodiment that the layers are arranged, and in that state, a foamable urethane resin is injected between the layers, foamed, and integrally laminated and molded.
[0009]
In the present invention, the heating device layer may be any layer, and all the heating device layers used in the conventional floor heating panel of this type can be used. For example, at least an aluminum foil layer as a heat equalizing layer and a layer of a PTC heater are provided, and both surfaces of the PTC heater are further covered with a resin film such as a PET film, if necessary. A layer having a layer composed of an aluminum foil layer as a layer and a wire heater fused thereto is a preferable layer structure. Of course, in any of the layer structures, the conductive wires and connectors to the heater are attached in the same manner as a conventional laminate of this type.
[0010]
In the present invention, the coating layer is optional as long as it covers the back surface of the resin foam layer and can suppress the thermal behavior of the coated resin foam surface, but a resin film such as kraft paper or a PET film is preferable. is there. Of course, depending on the foam molding conditions of the foamable resin at the time of integral molding and the thermal behavior characteristics of the heating material layer laminated and integrated on the front side, etc., the optimal coating layer to be laminated on the back side of the resin foam should be provided. Since the physical properties (optimal physical properties that do not cause warpage over time) are different, it is recommended to experimentally select a coating layer having the optimal physical properties including the type and thickness according to the situation. .
[0011]
The present invention also discloses a floor heating panel in which the laminate for a floor heating panel as described above is accommodated in an accommodation recess formed on the back surface side of the base material. The floor heating panel base material can be basically used as long as a concave portion capable of accommodating the laminate is formed on the back surface of the floor material used in the conventional flooring. Of course, if necessary, a notch for wiring, a space for accommodating the connector, and the like are formed. Although not essential, it is preferable that a decorative material such as a veneer is attached to the surface of the base which is a wood fiber board such as plywood or MDF, and that a fruit is preferably formed around the base. A pseudo groove is preferably formed in the decorative material.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a perspective view showing an example of a laminate for a floor heating panel according to the present invention, and FIG. 2 is a view showing a partially exploded state thereof. The floor heating panel laminate 10 is formed by integrally laminating a heating element layer 20, a resin foam layer 30 as a heat insulating layer, and a coating layer 40 covering the back surface of the resin foam layer 30 in this order. It is configured.

As the heating device layer 20, any one used as a heating device layer in conventional floor heating can be used arbitrarily. In this example, an aluminum foil (of about 0.1 mm thickness) 21 as a heat equalizing layer, a nonwoven fabric 22, a PET film 23, a PTC heater 24, and a PET film 25 are laminated in this order. A form in which a wire heater is fused to an aluminum foil may be used. Note that a male connector 26 and a female connector 27 for performing electrical connection are attached to the heating element layer 20 by an appropriate method.
[0014]
In this example, the resin foam layer 30 is made of hard urethane foam, but may be made of styrene foam. The coating layer 40 is optional as long as it covers the back surface of the resin foam layer 30 and can suppress the thermal behavior of the coated resin foam surface. In this example, kraft paper of about 75 g / m 2 is used, but a resin film such as a PET film may be used.
[0015]
The heating element layer 20, the resin foam layer 30, and the coating layer 40 are integrally laminated by an appropriate method to form the floor heating panel laminate 10. Preferably, as shown in FIG. 3, the heating element layer 20 is disposed on the bottom side of the mold 7, and the covering layer 40 is disposed on the lid 8, and a foamable urethane resin is injected therebetween to form the urethane. The heating device layer 20 and the coating layer 40 are integrally laminated on the front and back surfaces of the foamed urethane layer (resin foam layer 30). In the floor heating panel laminate 10 according to the present invention, one surface of the resin foam layer 30 which is a heat insulating layer is covered with the heating material layer 20 and the other surface is covered with the covering layer 40. The heat shrinkage ratio on the front and back surfaces of the resin foam layer 30 can be substantially the same, and the occurrence of warpage in the floor heating panel laminate 10 due to the difference in heat shrinkage is substantially suppressed. You. When styrene foam is used as the resin foam layer 30, the heating element layer 20 and the covering layer 40 may be bonded and integrated with an adhesive.
[0016]
As shown in FIG. 4, the floor heating panel laminate 60 according to the present invention is housed in the housing recess 51 formed on the back surface side of the floor heating panel base material 50, as shown in FIG. Is formed. As the floor heating panel base material 50, this type of base material used in conventional flooring can be arbitrarily used. In this example, the accommodation concave portion 51 is formed by hollowing out the back surface of the flat MDF, and cavities 52 and 53 for accommodating the male connector 26 and the female connector 27 are formed around the concave portion. The actual processing 54 is applied to the four corners of the opening. A decorative material 55 such as a veneer is adhered to the surface side of the floor heating panel base material 50, and a pseudo groove 56 is formed therein (see FIG. 5A).
[0017]
The size and depth of the housing recess 51 are the size and depth at which the floor heating panel laminate 10 is housed without any gap therein, and the housing recess 51 is bonded inside the housing recess 51 as shown in FIG. After applying the agent S, the floor heating panel laminate 10 is inserted into the uncured state of the adhesive S and the adhesive is cured (FIG. 4B). FIG. 5 shows the state after curing (that is, the floor heating panel 60 according to the present invention). As shown in the cross-sectional view of FIG. It is housed in the housing recess 51 so as to form the same plane as the back surface of the material 50, and is integrated with the floor heating panel base material 50 by an adhesive.
[0018]
FIG. 6 shows a state in which the floor heating panel 60 formed as described above is laid on the floor base material 1 such as a laminating plate in the same manner as in the related art. The occurrence of warpage in the floor heating panel laminate 10 is suppressed, and as a result, the floor heating panel 60 does not warp over time. There is no gap between the heating panel 60 and the rear surface, and floor noise does not occur due to the pressing force when the pedestrian walks.
[0019]
【The invention's effect】
According to the present invention, the occurrence of warpage in the floor heating panel laminate is suppressed, and as a result, the floor heating panel does not warp over time. Therefore, even if the floor heating panel is directly placed on the floor base material and the flooring is constructed, no gap is generated, and the floor squealing phenomenon occurs due to the pressing force when the pedestrian walks. It can be blocked for a long time.
