Description

施工性に優れ、暖房効率の良い暖房床構造とその施工方法を提供する。   To provide a heated floor structure with excellent workability and high heating efficiency and its construction method.

集合住宅その他において、遮音性等の面から、床スラブ上に複数の支持具を用いて、その上部に床構造を構成する2重床(乾式2重床とも称される)が採用されてきた。この様な2重床での床暖房に於いては、構成材料に与える温度変化が大きく、構成材料の寸法変化も大きくなる為、支持具上にパーティクルボード等の下地材と合板等の捨て張り材を敷き並べる等の寸法変化対策をしてから、温水パイプを挿入した床暖房パネルと床仕上げ材を敷設することにより施工されてきた。こうした従来技術において、遮音性、施工性、断熱性等の性能の改善を目的とした種々の試みがなされてきた。   In apartment houses and others, a double floor (also referred to as a dry double floor) that uses a plurality of supports on the floor slab and forms a floor structure on the floor slab has been adopted in terms of sound insulation and the like. . In such floor heating with double floors, the temperature change applied to the component material is large, and the dimensional change of the component material is also large. Therefore, the base material such as particle board and plywood are thrown away on the support. After taking measures against dimensional changes such as laying materials, it has been constructed by laying floor heating panels and floor finishes with hot water pipes inserted. In such conventional techniques, various attempts have been made to improve performance such as sound insulation, workability, and heat insulation.

例えば、捨て張り材の代わりに繊維板層とアスファルト層とを張り合わせた二層で構成される断熱遮音シートを用いて暖房温水マットを敷設する技術がある。そして、この技術で使用する暖房温水マットは、所定間隔毎に暖房温水マットの厚みと同じ深さのスリット内に設けた小根太に床材を釘打ちする構造としたものがある(特許文献1参照)。   For example, there is a technique of laying a heating and hot water mat using a heat insulating sound insulation sheet composed of two layers in which a fiberboard layer and an asphalt layer are bonded to each other in place of a discarded tension material. And the heating hot water mat used by this technique has a structure which nails a floor material to the small joist provided in the slit of the same depth as the thickness of the heating hot water mat for every predetermined interval (patent document 1). reference).

この特許文献1では二層構造の断熱遮音シートが必須であり、重量が増大すること、シート設置の手間が生ずることに加え、床暖房パネルに小根太を設けるので、更に手間と費用が必要となる。   In this patent document 1, the heat insulation sound insulation sheet of a two-layer structure is essential, and in addition to the increase in weight and the trouble of installing the sheet, since the floor heating panel is provided with a small joist, further labor and cost are required. Become.

別の試みとしては、捨て張り材や断熱遮音シート、小根太を用いない技術もある(特許文献2参照)。この技術では、小根太を挿入する手間やコストは省略できるものの、床仕上げ材は床暖房パネルに釘打ち出来ないことから該床暖房パネルに接着する必要がある。しかし、床仕上げ材を床暖房パネルに接着すると、床仕上げ材を張り替える際には、床仕上げ材が旨く剥離出来ず、床暖房パネルを損傷してしまうので、結局は床仕上げ材と共に、床暖房パネルをも同時に剥離してしまわなければならず、床暖房パネルの再使用が不可能となる。このため、必要以上に大きな工事となり、時間やコストのかかるものになってしまうという大きな支障が生ずる。また、床暖房パネルは、下地材(ベース板)上に隙間を開けて敷設するので、断熱性能が劣るものになってしまう。   As another attempt, there is a technique that does not use a litter material, a heat insulating sound insulation sheet, or a small joist (see Patent Document 2). In this technique, the labor and cost of inserting the small joists can be omitted, but the floor finish cannot be nailed to the floor heating panel, so it is necessary to adhere to the floor heating panel. However, if the floor finish is bonded to the floor heating panel, the floor finish cannot be peeled off properly when the floor finish is replaced, resulting in damage to the floor heating panel. The heating panel must be peeled off at the same time, making it impossible to reuse the floor heating panel. For this reason, the construction becomes larger than necessary, resulting in a great trouble that it takes time and cost. Moreover, since the floor heating panel is laid with a gap on the base material (base plate), the heat insulation performance is inferior.

本発明によれば、床暖房において、床暖房パネルを下地材に接着して、熱による寸法変化を制御することで捨て張り材の省略を可能とすると共に、発泡合成樹脂からなる基板の上面に、該基板の厚みより薄い床仕上材止着部を一体成形又は挿入により埋設した簡易な床暖房パネルを用いる故に、安価で製造が容易である。当該床暖房パネルを用い、該床暖房パネルを下地材に接着して実質隙間なく敷設し、本発明の暖房床構造は、施工性がよく、しかも強度に優れ、暖房効率が良好な暖房床構造を提供することができる。   According to the present invention, in floor heating, the floor heating panel is bonded to the base material, and the dimensional change due to heat is controlled, so that it is possible to omit the discarded tension material, and on the upper surface of the substrate made of foamed synthetic resin. Since a simple floor heating panel in which a floor finishing material fixing portion thinner than the thickness of the substrate is embedded by integral molding or insertion is used, it is inexpensive and easy to manufacture. Using the floor heating panel, the floor heating panel is bonded to the base material and laid without substantial gaps, and the heating floor structure of the present invention has good workability, excellent strength, and good heating efficiency. Can be provided.

更に、本発明の暖房床を施工後、リフォーム等で床仕上材を交換する場合には、床仕上材のみの剥離、張替えが容易に可能で、床仕上材の下部に敷設されている床暖房パネルに損傷を与えることなく、床暖房パネルをそのまま再使用できるという大きな効果を奏する。また、発泡合成樹脂製基板の表面に非発泡合成樹脂製シートを積層する際、シートの構成成分が発泡合成樹脂製基板と同じ系統の合成樹脂である場合には、両者の積層が容易でかつ床暖房パネルの強度が優れたものとなる。   Furthermore, when replacing the floor finishing material by renovation etc. after constructing the heating floor of the present invention, only the floor finishing material can be easily peeled off and replaced, and the floor heating laid at the bottom of the floor finishing material There is a great effect that the floor heating panel can be reused as it is without damaging the panel. In addition, when laminating a non-foamed synthetic resin sheet on the surface of a foamed synthetic resin substrate, if the component of the sheet is a synthetic resin of the same system as the foamed synthetic resin substrate, both can be easily laminated and The strength of the floor heating panel will be excellent.

本発明の床構造に用いる下地材としては、床の荷重を支えることができるものであれば特に限定はないが、用いることができる材料としては例えば、パーティクルボード、木毛繊維板、合板等を用いることができる。厚さは床の荷重を支えることができれば特に限定はないが、具体的には12mm〜36mm程度が例示できる。   The base material used in the floor structure of the present invention is not particularly limited as long as it can support the load on the floor, but examples of the material that can be used include particle board, wood fiberboard, and plywood. Can be used. The thickness is not particularly limited as long as it can support the load on the floor, but specifically, about 12 mm to 36 mm can be exemplified.

下地材を支持具を用いて設置する場合、支持具は高さ調整ができるものが好ましい。下地材は高さ調整できる支持具を用いて設置する場合、適宜隙間を設けておくとドライバー等を挿入させて支持具の軸部を回転させて微妙な高さ調整が出来るので好ましい。   When the base material is installed using a support, it is preferable that the support can be adjusted in height. When the base material is installed using a support whose height can be adjusted, it is preferable that a gap be provided as appropriate, since a screw or the like can be inserted and the shaft portion of the support can be rotated to finely adjust the height.

支持具はスラブに床の荷重を伝える脚部と、下地材の荷重を受ける板支持部を設けておくことが好ましい。また脚部と板支持部の間には軸部を設けておくことが好ましい。
脚部、板支持部、軸部のいずれかにねじ構造等による高さ調整ができる構造を設けておくことでレベル調整が可能となり、下地材ひいては暖房床の不陸を容易に調整することが可能となる。支持具を用いて2重床となすことで遮音性が向上し好ましい。この場合、支持具例えばゴム製の脚部を用いることにより脚部に緩衝機能を設けることによりさらに本願発明の床構造の遮音性が高めることができるので好ましい。
It is preferable that the support is provided with a leg portion that transmits the load of the floor to the slab and a plate support portion that receives the load of the base material. Moreover, it is preferable to provide a shaft part between the leg part and the plate support part.
It is possible to adjust the level by providing a structure that can adjust the height by screw structure etc. in any of the leg part, plate support part, shaft part, and it is possible to easily adjust the base material and thus the unevenness of the heating floor It becomes possible. Using a support to form a double floor is preferable because sound insulation is improved. In this case, it is preferable to use a support, for example, a rubber leg, to provide a cushioning function for the leg, since the sound insulation of the floor structure of the present invention can be further improved.

下地材と板支持部はビス又は釘にて固定するのが好ましい。また、下地材は固定する前に両面粘着テープ等で支持具の板支持部に仮止めしておくと下地材の設置や、高さ調整を容易行うことができる。    The base material and the plate support are preferably fixed with screws or nails. In addition, if the base material is temporarily fixed to the plate support portion of the support with a double-sided adhesive tape or the like before fixing, the base material can be easily installed and the height can be adjusted.

床暖房パネルは、発泡合成樹脂からなる基板の上面に、該基板の厚みより薄い床仕上材止着部を一体成形又は挿入により面一に埋設し、かつ、熱媒体配管を嵌挿したものを用いることができる。   In the floor heating panel, a floor finishing material fastening portion thinner than the thickness of the substrate is embedded on the top surface of the substrate made of foamed synthetic resin in a single surface by integral molding or insertion, and a heat medium pipe is inserted. Can be used.

また後述する非発泡合成樹脂製シートをその表面に設け、該シート表面と床仕上材止着部を面一に埋設する事も可能である。   Further, a non-foamed synthetic resin sheet, which will be described later, can be provided on the surface, and the sheet surface and the floor finishing material fixing portion can be embedded in the same plane.

基板を構成する発泡合成樹脂は、オレフィン系合成樹脂発泡体、スチレン系合成樹脂発泡体、ウレタン系合成樹脂発泡体等を用いることができる。オレフィン系合成樹脂発泡体としてはポリエチレン、ポリプロピレン等をあげることができ、スチレン系合成樹脂発泡体としてはポリスチレン等をあげることができ、ウレタン系合成樹脂発泡体としてはポリウレタン等をあげることができる。   As the foamed synthetic resin constituting the substrate, an olefin-based synthetic resin foam, a styrene-based synthetic resin foam, a urethane-based synthetic resin foam, or the like can be used. Examples of the olefin-based synthetic resin foam include polyethylene and polypropylene, examples of the styrene-based synthetic resin foam include polystyrene and the like, and examples of the urethane-based synthetic resin foam include polyurethane.

これらの内、コストや断熱性の点から、スチレン系合成樹脂発泡体からなる基板を用いるのが最も好ましい。スチレン系合成樹脂発泡体としてポリスチレン系合成樹脂発泡体が好ましく、発泡倍率としては、3〜30倍程度、さらに好ましくは5〜20倍程度が好ましい。   Among these, it is most preferable to use a substrate made of a styrene synthetic resin foam from the viewpoint of cost and heat insulation. As the styrene synthetic resin foam, a polystyrene synthetic resin foam is preferable, and the expansion ratio is preferably about 3 to 30 times, more preferably about 5 to 20 times.

床暖房パネルは、こうした発泡合成樹脂からなる基板の上面には、基板の厚みより薄い床仕上材止着部が、一体成形により基板の上面と面一に埋設されているものを用いることができる。あるいは、基板の上面に凹部あるいは凹溝を設け、床仕上材止着部を、これら凹部あるいは凹溝中に挿入し、嵌合、接着等により基板の上面と面一に埋設固定されたものを用いることができる。   In the floor heating panel, a floor finishing material fixing portion thinner than the thickness of the substrate is embedded on the upper surface of the substrate made of the synthetic foam resin so as to be flush with the upper surface of the substrate by integral molding. . Alternatively, a concave or concave groove is provided on the upper surface of the substrate, and a floor finish fixing part is inserted into the concave or concave groove, and is embedded and fixed flush with the upper surface of the substrate by fitting, bonding, etc. Can be used.

床仕上材止着部の形状としては、発泡合成樹脂からなる基板との固定を確実にするために、それぞれに予め設けられた凹凸による嵌合構造を有していることが好ましい。   As the shape of the floor finishing material fixing portion, it is preferable to have a fitting structure with concavities and convexities provided in advance in order to ensure fixation with the substrate made of foamed synthetic resin.

本発明において、床暖房パネルの基板として、スチレン系合成樹脂発泡体を使用する場合、スチレン系合成樹脂発泡体の内でも、ビーズ法によるスチレン系合成樹脂発泡体、すなわち型内発泡成形法によるスチレン系合成樹脂発泡体が最も好ましい。型内発泡成形法によると、基板の厚みより薄い床仕上材止着部を、一体成形により基板の上面と面一に埋設固定するのを容易に行うことができ好ましい。   In the present invention, when a styrene synthetic resin foam is used as a substrate for a floor heating panel, among styrene synthetic resin foams, a styrene synthetic resin foam by a bead method, that is, styrene by an in-mold foam molding method. A synthetic resin foam is most preferred. According to the in-mold foam molding method, it is preferable that the floor finishing material fixing portion thinner than the thickness of the substrate can be easily embedded and fixed flush with the upper surface of the substrate by integral molding.

すなわち、成形型内に床仕上材止着部を固定して、予備発泡スチレン系合成樹脂粒子(ビーズ)を充填し、水蒸気等の熱媒を型内に導入して一体成形すれば、接着剤等を使用しなくとも、床仕上材止着部は基板と強固に一体となる。このため、床暖房パネルの全体の強度が高くなり、遮音性能や断熱性の面でも好ましく、成形性も良好であるので工業的に有利である。   That is, fixing the floor finishing material fixing part in the mold, filling the pre-expanded styrene synthetic resin particles (beads), introducing a heat medium such as water vapor into the mold and integrally molding the adhesive, Even if it is not used, the floor finishing material fixing portion is firmly integrated with the substrate. For this reason, the intensity | strength of the whole floor heating panel becomes high, is preferable also from the surface of sound-insulation performance and heat insulation, and since a moldability is also favorable, it is industrially advantageous.

この場合も床仕上材止着部には合成樹脂発泡体との接合をより確実にするため、合成樹脂発泡体と接合する部分に凹凸を設けておくことが好ましい。   Also in this case, it is preferable that the floor finishing material fastening portion is provided with unevenness in the portion to be joined to the synthetic resin foam in order to ensure the joining with the synthetic resin foam.

床仕上材止着部の材質としては、木材、合成木材等を用いることができる。合成木材は、断熱性能や耐湿性が良好であり好ましく、また、木材はくぎ抜き強度に優れているので好ましい。合成木材としては、一般に合成木材として使用されているものは使用可能である。特に、低発泡倍率の発泡合成樹脂製の合成木材が好ましく使用できる。低発泡倍率の発泡合成樹脂としてはスチレン系合成樹脂やABS樹脂をあげることができるが、スチレン系合成樹脂がコストや断熱性の点で好ましい。その内でもポリスチレン樹脂が好ましい。スチレン系合成樹脂やABS樹脂を用いる場合の発泡倍率としては、1.3〜10倍程度、さらに好ましくは1.5〜3倍程度が好ましいが、基板の発泡倍率より低いことが好ましい。   As the material for the floor finishing material fastening portion, wood, synthetic wood or the like can be used. Synthetic wood is preferable because of its good heat insulation performance and moisture resistance, and wood is preferable because of its excellent nail-breaking strength. As synthetic wood, what is generally used as synthetic wood can be used. In particular, synthetic wood made of foamed synthetic resin having a low foaming ratio can be preferably used. Examples of the foamed synthetic resin having a low expansion ratio include styrene-based synthetic resins and ABS resins, but styrene-based synthetic resins are preferable in terms of cost and heat insulation. Among them, polystyrene resin is preferable. When the styrene synthetic resin or ABS resin is used, the expansion ratio is preferably about 1.3 to 10 times, more preferably about 1.5 to 3 times, but is preferably lower than the expansion ratio of the substrate.

合成樹脂製の床仕上材止着部は、型内発泡成形法あるいは押出し成形法により製造することができるが、押出し成形法により製造するのが効率的で好ましい。   The synthetic resin floor finishing material fixing portion can be manufactured by an in-mold foam molding method or an extrusion molding method, but it is efficient and preferable to manufacture by a extrusion molding method.

床仕上材止着部の厚みは、5mm〜34mm程度、幅は、25mm〜65mm程度が例示でき好ましい。基板に設ける箇所は、基板上に筋状に設けていても良く、規則的に部分的に設けていても良い。部分的に設ける場合は、筋状である必要はなく、方形、丸形等特に限定されない。   The thickness of the floor finishing material fastening portion is preferably about 5 mm to 34 mm, and the width is preferably about 25 mm to 65 mm. The portions provided on the substrate may be provided in a streak pattern on the substrate or may be provided regularly and partially. When partially provided, it is not necessary to have a streak shape, and there is no particular limitation such as a square shape or a round shape.

床暖房パネルを構成する基板の上面には、床仕上材止着部が埋設されるほか、基板の上面には熱媒体配管を嵌挿するためのU字溝を設けている。熱媒体配管は、温湯等の熱媒体を循環させて、暖房に供することができるが、熱媒体配は電気による発熱体であっても構わない。   A floor finishing material fixing portion is embedded on the upper surface of the substrate constituting the floor heating panel, and a U-shaped groove for inserting the heat medium pipe is provided on the upper surface of the substrate. The heat medium pipe can circulate a heat medium such as hot water to be used for heating, but the heat medium distribution may be an electric heating element.

床暖房パネルの厚さは12mm〜36mm程度である。床暖房パネルの大きさは、施工する場所の広さや施行方法に応じて種々のものが使用でき特に限定はできないが、例えば、150mm×230mm程度のものから1170mm×2580mm程度の大きさのものが好適に用いることができる。   The thickness of the floor heating panel is about 12 mm to 36 mm. There are various types of floor heating panels that can be used depending on the size of the place of construction and the method of implementation, and there is no particular limitation. For example, the floor heating panel has a size of about 150 mm × 230 mm to about 1170 mm × 2580 mm. It can be used suitably.

本発明における床暖房パネルは、基板の片表面又は両表面に、非発泡合成樹脂製シートを積層することができる。非発泡合成樹脂製シートを積層することで、表面強度が向上するとともに、床暖房パネル全体としての圧縮強度等の各種強度も向上するので特に好ましい。   The floor heating panel in the present invention can be laminated with a non-foamed synthetic resin sheet on one or both surfaces of the substrate. Laminating non-foamed synthetic resin sheets is particularly preferable because surface strength is improved and various strengths such as compressive strength of the entire floor heating panel are also improved.

非発泡合成樹脂製シートとしては特に限定はなく、具体的にはスチレン系樹脂、ABS樹脂、アクリル樹脂、ポリオレフィン樹脂をあげることができる。   The non-foamed synthetic resin sheet is not particularly limited, and specific examples include styrene-based resins, ABS resins, acrylic resins, and polyolefin resins.

非発泡合成樹脂製シートとしては、基板と構成成分が同じ系統の成分を含有する合成樹脂からなるシートを使用するのが好ましい。例えば、基板が、スチレン系合成樹脂発泡体である場合に、スチレン系合成樹脂であることが好ましい。   As the non-foamed synthetic resin sheet, it is preferable to use a sheet made of a synthetic resin containing components of the same component as the substrate. For example, when the substrate is a styrene synthetic resin foam, it is preferably a styrene synthetic resin.

スチレン系合成樹脂シートとしてはハイインパクトポリスチレン樹脂製シートが好ましく用いることができる。   As the styrene synthetic resin sheet, a high impact polystyrene resin sheet can be preferably used.

このように、基板と構成成分が同じ系統の成分を含有する非発泡合成樹脂製シートを使用することにより、基板と非発泡合成樹脂製シートの積層が容易で、例えば熱接着が可能となり、接着剤量の減少あるいは省略が出来ると共に、接着強度も高いものが容易に得られる。   In this way, by using a non-foamed synthetic resin sheet containing components of the same system as the substrate and constituent components, it is easy to laminate the substrate and the non-foamed synthetic resin sheet, for example, thermal bonding becomes possible, The amount of the agent can be reduced or omitted, and the adhesive strength can be easily obtained.

非発泡合成樹脂製シートの表面に、熱伝導性の良好な伝導層を設けておくと、熱伝導を高めたり、表面へ熱がより均一に伝わり仕上げ材表面の温度分布が少なくなるので好ましい。伝導層としては金属製の薄膜が好ましい。その際、予めシート表面に金属薄膜を設けておくと、施行時に熱伝導性を向上する手間を省くことができる。また、金属薄膜を設ける方法としては金属の蒸着による方法によれば、金属箔等からなる伝導層を別途積層する手間を省略することができる。この非発泡合成樹脂製シートへ伝導層を設ける場合、積層しようとする基板とは、反対側の表面に設けるのが、基板との接着性を低下させないで熱伝導を高めるのに好ましい。   It is preferable to provide a conductive layer having good thermal conductivity on the surface of the non-foamed synthetic resin sheet, because heat conduction is increased or heat is more uniformly transferred to the surface and the temperature distribution on the surface of the finished material is reduced. A metal thin film is preferred as the conductive layer. At that time, if a metal thin film is provided on the surface of the sheet in advance, it is possible to save the trouble of improving the thermal conductivity at the time of enforcement. In addition, as a method of providing a metal thin film, according to a method by metal vapor deposition, the labor of separately laminating a conductive layer made of a metal foil or the like can be omitted. When the conductive layer is provided on the non-foamed synthetic resin sheet, it is preferable to provide the conductive layer on the surface opposite to the substrate to be laminated in order to increase the heat conduction without deteriorating the adhesion to the substrate.

また、非発泡合成樹脂製シートと伝導層を別々に設けてもかまわない。例えば、非発泡合成樹脂製シートを基板の裏側および又は表側に設けさらに伝導層を表側に設けても構わない。また、伝導層となる金属薄膜だけを基板表面に設けても構わない。   Further, a non-foamed synthetic resin sheet and a conductive layer may be provided separately. For example, a non-foamed synthetic resin sheet may be provided on the back side and / or the front side of the substrate, and a conductive layer may be provided on the front side. Moreover, you may provide only the metal thin film used as a conductive layer on the substrate surface.

床暖房パネルの表面に設けられたU字溝中には、熱媒体配管を嵌挿して配置する。温湯等の熱媒体を循環させて、暖房に供する熱媒体配管としては、金属製、合成樹脂製等、通常床暖房に用いることができるものであれば特に限定なく用いることができる。金属製パイプとしては、ステンレス、銅、が用いることができ、合成樹脂製パイプとしてはポリオレフィン製パイプを用いることができる。ポリオレフィン製パイプとしては、ポリエチレン製パイプがもっぱら多用されており好ましい。これらパイプをパネルに設けられているU字溝に嵌挿して配置することができる。   In the U-shaped groove provided on the surface of the floor heating panel, a heat medium pipe is inserted and arranged. As the heat medium pipe for circulating the heat medium such as hot water to be used for heating, there can be used without particular limitation as long as it can be used for normal floor heating such as metal or synthetic resin.

本発明においては、スラブ上に下地材を敷設し、該下地材上に、床仕上材止着部を一体成形又は接着により面一に埋設し、かつ、熱媒体配管を嵌挿した基板からなる床暖房パネルを接着により敷設し、下地材と床暖房パネルとの熱による寸法変化を抑止させ、更に、該床暖房パネル上に、床仕上材を敷設することにより、本発明の暖房床構造は形成することができる。また、スラブ上に配置した支持具上に下地材を敷設して2重床構造暖房床構造となす事も可能である。

In the present invention, the base material is laid on the slab, and the floor finishing material fixing portion is embedded on the same surface by integral molding or adhesion, and the heat medium pipe is inserted into the base material. By laying the floor heating panel by bonding, suppressing the dimensional change due to heat between the base material and the floor heating panel, and further laying the floor finishing material on the floor heating panel, the heating floor structure of the present invention is Can be formed. Moreover, it is also possible to construct a double floor structure heating floor structure by laying a base material on a support member arranged on a slab.

以下、本発明を図面に基づいて説明する。   Hereinafter, the present invention will be described with reference to the drawings.

図1は本発明の床構造の一例を示す断面図である。集合住宅等の床スラブ1上に、複数個の支持具2を立設させ、パーティクルボードである下地材3を敷設している。この下地材3は支持具2の軸部2aに螺着された板支持部2bに架設させる形となしている。支持具2の軸部2aは、脚部2c上に設置されている。下地材3は設置の際、支持具2の上に隙間なく敷き詰めることはせず、適宜隙間を設けている。下地材3は、支持具2の板支持部2bに仮止めしてた後、高さ調整後、ビス又は釘にて固定している。   FIG. 1 is a cross-sectional view showing an example of the floor structure of the present invention. A plurality of supports 2 are erected on a floor slab 1 such as an apartment house, and a base material 3 that is a particle board is laid. The base material 3 is formed on a plate support portion 2b that is screwed to the shaft portion 2a of the support 2. The shaft 2a of the support 2 is installed on the leg 2c. When the base material 3 is installed, the base material 3 is not spread on the support 2 without a gap, and a gap is provided as appropriate. After the base material 3 is temporarily fixed to the plate support portion 2b of the support 2, the height is adjusted and then fixed with screws or nails.

上記のごとく設置した下地材3の上に、床暖房パネル4を実質隙間なく接着により敷設する。実質的に隙間なく敷設することにより、発泡合成樹脂からなる基板を構成要素とする床暖房パネル4の本来の断熱性能を、充分に発揮させることが出来る。この敷設では、下地材3と床暖房パネル4とを接着することで、床暖房パネル4の温度変化による寸法変化と、下地材3の温度変化による寸法変化とによる影響を最小限に抑えて、捨て張り材の省略による弊害を解消することが可能となる。   On the base material 3 installed as described above, the floor heating panel 4 is laid by adhesion without substantial gaps. By laying substantially without any gap, the original heat insulation performance of the floor heating panel 4 having a substrate made of foamed synthetic resin as a constituent element can be sufficiently exhibited. In this laying, by bonding the base material 3 and the floor heating panel 4, the influence of the dimensional change due to the temperature change of the floor heating panel 4 and the dimensional change due to the temperature change of the base material 3 is minimized, It is possible to eliminate the harmful effects caused by the omission of the discarding material.

図1で使用している床暖房パネル4は発泡ポリスチレン樹脂製の基板4aで形成(発泡倍率は、例えば10倍程度)されており、基板4aの表面には、嵌合構造を設けた合成木材(発泡倍率2倍程度の発泡ポリスチレン樹脂)からなる仕上材止着部5を一体成形により基板4aの表面と面一に埋設して存在させている。又は、基板4aの上面に、基板4aの厚さよりも浅い深さの凹溝4c(図2参照)を設け、凹溝4cの深さと同じ厚みの床仕上材止着部5を、該凹溝4cに挿入し、必要により接着等により止着し、基板4aの表面と面一に埋設して存在させることもできる。   The floor heating panel 4 used in FIG. 1 is formed of a foamed polystyrene resin substrate 4a (foaming magnification is about 10 times, for example), and a synthetic wood provided with a fitting structure on the surface of the substrate 4a. The finishing material fastening portion 5 made of (foamed polystyrene resin having a foaming ratio of about 2 times) is embedded and is flush with the surface of the substrate 4a by integral molding. Alternatively, a concave groove 4c (see FIG. 2) having a depth shallower than the thickness of the substrate 4a is provided on the upper surface of the substrate 4a, and the floor finish material fixing portion 5 having the same thickness as the depth of the concave groove 4c is provided in the concave groove. It can also be inserted into 4c, fastened by adhesion or the like, if necessary, and embedded in the surface of the substrate 4a.


図2では、表面に熱媒体配管6を嵌挿するU字溝7を形成した基板4aの表面に、その表面形状に沿って、非発泡合成樹脂製シート4bを積層している。また、U字溝7を形成した基板4aの表面とは反対の面(図3参照)あるいは両面に非発泡合成樹脂製シート4bを積層してもかまわない。また、図4に示すようにU字部分を避けて設けることも可能である。

In FIG. 2, a non-foamed synthetic resin sheet 4 b is laminated along the surface shape of the substrate 4 a having a U-shaped groove 7 into which the heat medium pipe 6 is inserted. Further, a non-foamed synthetic resin sheet 4b may be laminated on the surface opposite to the surface of the substrate 4a on which the U-shaped groove 7 is formed (see FIG. 3) or on both surfaces. Further, as shown in FIG. 4, it is possible to avoid the U-shaped portion.

図3ではU字溝7と反対側の面(裏面)に非発泡合成樹脂製シート4bを積層した場合の例である。更には、基板4aの上の表面にも非発泡合成樹脂製シート4bを積層することも出来る。    FIG. 3 shows an example in which a non-foamed synthetic resin sheet 4 b is laminated on the surface (back surface) opposite to the U-shaped groove 7. Furthermore, a non-foamed synthetic resin sheet 4b can also be laminated on the surface of the substrate 4a.

図3では、基板4aのU字溝7内に熱媒体配管6を嵌挿した後、基板4aの表面に、アルミ箔等の金属箔からなる伝導層8を貼着し、熱伝導性の均一化と効率を高めた例である。このように伝導層8を有する床暖房パネル4を採用するのが好ましい。図3では、伝導層8を熱媒体配管6の上から貼着した例を示したが、基板4aの表面に設けられたU字溝7内を含め、基板4aの表面に伝導層8を貼着した後、伝導層8が貼着されたU字溝7内に熱媒体配管6を嵌挿する態様も実施できる。   In FIG. 3, after the heat medium pipe 6 is inserted into the U-shaped groove 7 of the substrate 4a, a conductive layer 8 made of a metal foil such as an aluminum foil is pasted on the surface of the substrate 4a to make the heat conductivity uniform. This is an example of improving efficiency and efficiency. Thus, it is preferable to employ the floor heating panel 4 having the conductive layer 8. Although FIG. 3 shows an example in which the conductive layer 8 is attached from above the heat medium pipe 6, the conductive layer 8 is attached to the surface of the substrate 4a including the inside of the U-shaped groove 7 provided on the surface of the substrate 4a. After attaching, the aspect which inserts the heat carrier piping 6 in the U-shaped groove 7 to which the conductive layer 8 was stuck can also be implemented.

U字溝7内に伝導層8を貼着する実施態様は、伝導層8の貼着に手間が掛かるが、熱媒体配管6と伝導層8との接触面積が大きくなるので、熱媒体配管6からの熱を、効率よく伝導層8に伝達させることができ、更に、均一な温度分布を得る上でも好ましい。   In the embodiment of attaching the conductive layer 8 in the U-shaped groove 7, it takes time to attach the conductive layer 8, but the contact area between the heat medium pipe 6 and the conductive layer 8 becomes large. Can be efficiently transferred to the conductive layer 8, and it is also preferable for obtaining a uniform temperature distribution.

床暖房パネル4の上には、床仕上材9が敷設される。床仕上材9は、床暖房パネル4に埋設された床仕上材止着部5に釘等で止着することにより、本発明の暖房床構造となる。   A floor finishing material 9 is laid on the floor heating panel 4. The floor finishing material 9 is fixed to the floor finishing material fixing portion 5 embedded in the floor heating panel 4 with a nail or the like, thereby forming the heating floor structure of the present invention.

図4は、本発明で使用する床暖房パネル4の他の実施態様を示すものであって、基板4aのU字溝7を除いた表面部分のみに非発泡合成樹脂製シート4bを積層し、該U字溝7内に熱媒体配管6を嵌挿した例である。床仕上材止着部5の頂面は、非発泡合成樹脂製シート4bを積層した基板4aの表面と面一になるように一体成形又は挿入により埋設されている。そして、更に、熱媒体配管6、非発泡合成樹脂製シート4b、床仕上材止着部5の上面には、伝導層8が貼着された構成の床暖房パネル4を例示している。   FIG. 4 shows another embodiment of the floor heating panel 4 used in the present invention, in which a non-foamed synthetic resin sheet 4b is laminated only on the surface portion excluding the U-shaped groove 7 of the substrate 4a. In this example, the heat medium pipe 6 is inserted into the U-shaped groove 7. The top surface of the floor finishing material fastening portion 5 is embedded by integral molding or insertion so as to be flush with the surface of the substrate 4a on which the non-foamed synthetic resin sheet 4b is laminated. Further, the floor heating panel 4 having a configuration in which the conductive layer 8 is adhered to the upper surfaces of the heat medium pipe 6, the non-foamed synthetic resin sheet 4 b, and the floor finishing material fixing portion 5 is illustrated.
