特開平06−313357号公報
For installation of floor finishing materials (building materials) such as carpets on the floors of living rooms, metal foil underlay sheets (heated members) coated with hot-melt adhesive (hot-melt adhesive) on both sides After placing the floor finishing material such as carpet on the underlaying sheet (surface to be attached) and laying the flooring material on the flooring sheet, it is guided to the metal foil by irradiating the underlaying sheet from the surface of the flooring material. There has been proposed a “building material pasting method” in which an underlay sheet is heated by an electric current to melt a hot-melt adhesive on the surface thereof and adhere a floor finish (see Patent Document 1). Construction using hot-melt adhesive can be re-covered by the fact that the curing time of the adhesive is instantaneous and the workability is excellent, there is no generation of harmful substances such as formaldehyde, and the hot-melt adhesive is remelted. There are advantages such as what you can do.
Japanese Patent Laid-Open No. 06-313357

昨今は、フローリングの施工においても、ホットメルト接着剤を使用して床下地材にフローリングを接着する各種の方法が採用されている。フローリング施工においては、仕上材であるフローリングの種類がデザイン等により多種に及ぶため、被加熱部材およびホットメルト接着剤が予め付設された床下地材を使用するのが望ましい。すなわち、斯かるフローリング施工においては、床下地材として、例えば、その表面に被加熱部材である帯状の鋼製シートが一定間隔で配置され且つ鋼製シートの表面にホットメルト接着剤が貼付された床下地材を使用すると共に、床下地材の上にフローリングを配置した後、フローリング表面から鋼製シートを電磁誘導加熱し、鋼製シート表面のホットメルト接着剤を溶融することにより、床下地材にフローリングを接着する。   In recent years, various methods of bonding a flooring to a floor base material using a hot melt adhesive have been adopted in the construction of flooring. In flooring construction, the flooring material, which is a finishing material, varies depending on the design and the like. Therefore, it is desirable to use a floor base material provided with a member to be heated and a hot melt adhesive in advance. That is, in such flooring construction, for example, a strip-shaped steel sheet, which is a heated member, is arranged at regular intervals on the surface of the floor base material, and a hot melt adhesive is attached to the surface of the steel sheet. After using the floor base material and placing the flooring on the floor base material, the steel sheet is electromagnetically heated from the flooring surface to melt the hot melt adhesive on the surface of the steel sheet. Adhere the flooring.

ところで、上記の様なフローリング施工においては、所要時間電磁誘導加熱しているにも拘わらず、鋼製シート表面のホットメルト接着剤が部分的に溶融せず、フローリングが必ずしも鋼製シート全体に亘って接着していない場合がある。そして、斯かる問題について種々検討したところ、フローリングは平坦性が低く、床下地材に対する不陸状態が部位によって異なることに起因することが確認された。すなわち、床下地材の上に配置した場合、床下地材の鋼製シートとフローリングとの間に微小な隙間が生じ、かつ、これら隙間の大きさが一様でないため、電磁誘導によって鋼製シートに生じる誘導電流(うず電流)が不均一となり、鋼製シート全体が均一に加熱されないと言う問題がある。勿論、磁力線をより長時間照射するならば、ホットメルト接着剤を完全に溶融させ得るが、過剰な磁力線の照射により床下地材の基材を損傷すると言う問題がある。   By the way, in the flooring construction as described above, the hot melt adhesive on the surface of the steel sheet is not partially melted despite the electromagnetic induction heating for the required time, and the flooring does not necessarily extend over the entire steel sheet. May not adhere. As a result of various investigations on such a problem, it was confirmed that the flooring has low flatness, and the unevenness with respect to the floor base material varies depending on the part. That is, when arranged on the floor base material, a minute gap is generated between the steel sheet of the floor base material and the flooring, and the size of these gaps is not uniform. Inductive current (eddy current) generated in the steel becomes non-uniform, and the entire steel sheet is not heated uniformly. Of course, if the magnetic field lines are irradiated for a longer time, the hot melt adhesive can be completely melted, but there is a problem that the base material of the floor base material is damaged by the irradiation of the excessive magnetic field lines.

本発明は、上記の実情に鑑みてなされたものであり、その目的は、電磁誘導加熱によりホットメルト接着剤を溶融させてフローリングを貼り付けるための床下地材であって、より短時間で確実にフローリングを接着でき、一層効率的にフローリングを敷設できる床下地材、および、当該床下地材を使用したフローリングの施工方法を提供することにある。   The present invention has been made in view of the above circumstances, and an object of the present invention is a floor base material for melting a hot melt adhesive by electromagnetic induction heating and attaching a flooring, which can be reliably performed in a shorter time. It is intended to provide a floor base material that can adhere flooring to the floor and lay the flooring more efficiently, and a flooring construction method using the floor base material.

上記の課題を解決するため、本発明は、床下地材の基材表面に配置する帯状の金属製被加熱部材に多数の小孔を長さ方向に沿って多数設け、電磁誘導によって金属製被加熱部材に生じる誘導電流を各小孔の周囲に集中させることにより、金属製被加熱部材において略均一な加熱を可能にした。   In order to solve the above-mentioned problems, the present invention provides a large number of small holes along the length direction in a strip-shaped metal heating member disposed on the base material surface of a floor base material, and the metal coating by electromagnetic induction. By concentrating the induced current generated in the heating member around each small hole, the metal heated member can be heated substantially uniformly.

すなわち、本発明は2つの要旨から成り、その第1の要旨は、電磁誘導加熱によって表面にフローリングを貼り付けるための床下地材であって、基材表面に帯状の金属製被加熱部材が一定間隔で平行に配置され且つ当該金属製被加熱部材の表面にホットメルト接着剤が貼付されて成り、前記金属製被加熱部材には、その幅方向の略中央に且つ長さ方向に沿って多数の小孔が設けられていることを特徴とする床下地材に存する。   That is, the present invention comprises two gist, the first gist is a floor base material for attaching a flooring to the surface by electromagnetic induction heating, and a belt-like metal heated member is fixed on the surface of the base material. The metal heated members are arranged in parallel at intervals and a hot melt adhesive is applied to the surface of the metal heated member. A large number of the metal heated members are arranged substantially in the center in the width direction and along the length direction. The floor base material is characterized by being provided with small holes.

また、本発明の第2の要旨は、上記の床下地材を使用したフローリングの施工方法であって、床下地材の表面にフローリングを配置し、フローリング表面の金属製被加熱部材に相当する部位に磁力線を照射して金属製被加熱部材を誘導加熱し、金属製被加熱部材表面のホットメルト接着剤を溶融することにより、床下地材にフローリングを接着することを特徴とするフローリングの施工方法に存する。   Further, the second gist of the present invention is a flooring construction method using the above-mentioned floor base material, wherein the flooring is disposed on the surface of the floor base material, and the portion corresponding to the metal heated member on the floor surface A flooring construction method characterized by adhering a flooring material to a floor base material by inductively heating a metal heated member by irradiating a magnetic field line to the surface and melting a hot melt adhesive on the surface of the metal heated member Exist.

本発明によれば、フローリングの表面側から電磁誘導加熱した場合、金属製被加熱部材の幅方向の略中央に且つ長さ方向に沿って設けられた多数の小孔に誘導電流を集中させ、金属製被加熱部材をその全面に亘って略均一に加熱でき、ホットメルト接着剤を略均等に溶融させることが出来るため、より短時間で確実にフローリングを接着でき、そして、再施工などの必要がなく、一層効率的にフローリングを敷設できる。   According to the present invention, when electromagnetic induction heating is performed from the surface side of the flooring, the induced current is concentrated in a large number of small holes provided in the approximate center in the width direction and along the length direction of the metal heated member, The metal heated member can be heated almost uniformly over the entire surface, and the hot melt adhesive can be melted almost evenly, so that the flooring can be securely bonded in a shorter time, and reworking is required. The flooring can be laid more efficiently.

先ず、本発明の床下地材について説明する。本発明の床下地材は、いわゆる捨て貼り工法あるいは置き床工法によってフローリングを施工する際、床組の上に貼設され且つ電磁誘導加熱によって表面にフローリングを貼り付けるために使用される。本発明の床下地材は、図1に符号(1)で示す様に、基材表面に帯状の金属製被加熱部材(2)が一定間隔で平行に配置され且つ当該金属製被加熱部材の表面にホットメルト接着剤が貼付されて成る。   First, the floor base material of the present invention will be described. The floor base material of the present invention is used to paste a flooring onto a floor assembly and to apply the flooring to the surface by electromagnetic induction heating when the flooring is applied by a so-called discarding or placing floor method. In the floor base material of the present invention, as indicated by reference numeral (1) in FIG. 1, strip-shaped metal heated members (2) are arranged in parallel at regular intervals on the substrate surface, and the metal heated members A hot melt adhesive is stuck on the surface.

床下地材(1)の基材(金属製被加熱部材(2)以外の面材)は、通常、ベニヤ等の構造用合板やパーティクルボードによって構成される。床下地材(1)の基材は、施工性の観点から、通常は平面形状を長方形に形成され、幅が600〜1200mm程度、長さが1800〜2500mm程度に設計される。床下地材(1)の基材の厚さは、構成材料にもよるが、一般的には9〜20mm程度である。   The base material of the floor base material (1) (a face material other than the metal heated member (2)) is usually constituted by a structural plywood such as veneer or a particle board. From the viewpoint of workability, the base material of the floor base material (1) is usually designed to have a rectangular planar shape, a width of about 600 to 1200 mm, and a length of about 1800 to 2500 mm. The thickness of the base material of the floor base material (1) is generally about 9 to 20 mm, although it depends on the constituent materials.

また、床下地材(1)の基材としては、温水を通水可能に構成された構造体である次の様な床暖房用温水マットを使用することも出来る。すなわち、床暖房の施工に適用される床下地材(1)においては、図3に示す様に、基材として、一定間隔で平行に小根太(12)が配列された板状の発泡樹脂成形体(11)に通水パイプ(13)を埋設して成る床暖房用温水マットが使用される。そして、斯かる床下地材(1)において、ホットメルト接着剤が貼付された金属製被加熱部材(2)は小根太(12)の表面に配置される。   Moreover, as a base material of the floor base material (1), the following warm water mat for floor heating, which is a structure configured to allow warm water to flow, can be used. That is, in the floor base material (1) applied to the construction of floor heating, as shown in FIG. 3, as a base material, a plate-like foamed resin molding in which small joists (12) are arranged in parallel at regular intervals A hot water mat for floor heating is used, in which a water passage pipe (13) is buried in the body (11). In such a floor base material (1), the metal heated member (2) to which the hot melt adhesive is applied is arranged on the surface of the small joist (12).

具体的には、図3に示す床下地材(1)は、複数の板状の発泡樹脂成形体(11)と、発泡樹脂成形体(11)の間に一定間隔で介装された小根太(12)と、発泡樹脂成形体(11)の表層近傍に埋設された通水パイプ(13)と、発泡樹脂成形体(11)の表面に貼着された熱拡散用のアルミニウム箔(14)とから主として構成され、かつ、小根太(12)の表面に帯状の金属製被加熱部材(2)が貼付けられ且つ当該金属製被加熱部材の表面にホットメルト接着剤が貼付された構造を有する。床下地材(1)の基材が上記の様な床暖房用温水マットによって構成されている場合には、床暖房用の床を簡単に施工することが出来る。   Specifically, the floor base material (1) shown in FIG. 3 includes a plurality of plate-like foamed resin molded bodies (11) and small joists disposed at regular intervals between the foamed resin molded bodies (11). (12), a water pipe (13) embedded in the vicinity of the surface layer of the foamed resin molded body (11), and an aluminum foil for heat diffusion (14) adhered to the surface of the foamed resin molded body (11) And has a structure in which a band-shaped metal heated member (2) is attached to the surface of the small joist (12) and a hot melt adhesive is attached to the surface of the metal heated member. . In the case where the base material of the floor base material (1) is constituted by the hot water mat for floor heating as described above, the floor heating floor can be easily constructed.

床下地材(1)の上に貼り付けるフローリング(4)(図4参照)としては、マトア、チーク、オーク、ナラ、サクラ、ヒノキ、メープル、ウリン等の各種天然木材を少なくとも表面に使用した床仕上材が使用される。通常、フローリング(4)は、平面形状を細長の長方形に形成され、フローリング(4)の寸法仕様は、長さが900〜2000mm程度、幅が150〜350mm程度、厚さが3〜15mm程度とされる。   Flooring (4) (see Fig. 4) to be affixed on the floor base material (1) is a floor using at least the surface of various kinds of natural wood such as matoa, teak, oak, oak, cherry, cypress, maple and urine. Finishing material is used. In general, the flooring (4) is formed in an elongated rectangular plane shape, and the dimensions of the flooring (4) are about 900 to 2000 mm in length, about 150 to 350 mm in width, and about 3 to 15 mm in thickness. Is done.

図1に示す様に、床下地材(1)に配置される金属製被加熱部材(2)は、その幅を20〜60mm程度、厚さを0.1〜3mm程度に設計された例えば鋼製の薄板であり、斯かる薄板は、フローリング(4)を配置した際に当該フローリングの幅方向に薄板の長さ方向が沿う様に床下地材(1)の表面に例えば各種接着剤によって貼着される。金属製被加熱部材(6)を構成する金属としては、上記の鋼を含む鉄の他、アルミニウム合金、コバルト、ニッケル等の金属が挙げられる。各金属製被加熱部材(6)の配列ピッチは、例えば150〜650mmとされる。   As shown in FIG. 1, the metal heated member (2) arranged on the floor base material (1) is designed to have a width of about 20 to 60 mm and a thickness of about 0.1 to 3 mm, for example, steel. The thin plate is made of, for example, various adhesives on the surface of the floor base material (1) so that when the flooring (4) is arranged, the length direction of the thin plate is along the width direction of the flooring. Worn. As a metal which comprises a metal to-be-heated member (6), metals, such as aluminum alloy, cobalt, nickel other than iron containing said steel, are mentioned. The arrangement pitch of the metal heated members (6) is, for example, 150 to 650 mm.

金属製被加熱部材(2)の表面に貼付されるホットメルト接着剤としては、一般的にはポリエチレン、ポリイソブチレン、ポリアミド、酢酸ビニル−エチレン共重合体などの公知の各種熱可塑性樹脂が使用される。なお、上記の床下地材(1)としては、工場での加工により金属製被加熱部材(2)が予め付設されたものを使用してもよいが、現場施工により金属製被加熱部材(2)を付設したものでもよく、また、ホットメルト接着剤も、現場施工により金属製被加熱部材(2)の表面に貼付されてもよい。   As the hot melt adhesive to be applied to the surface of the metal heated member (2), various known thermoplastic resins such as polyethylene, polyisobutylene, polyamide, vinyl acetate-ethylene copolymer are generally used. The In addition, as said floor base material (1), you may use what the metal heated member (2) was previously attached by the process in a factory, However, Metal heated member (2 by site construction) ) Or a hot melt adhesive may be attached to the surface of the metal heated member (2) by on-site construction.

本発明においては、基材表面の各金属製被加熱部材(2)をそれぞれに均一に加熱するため、図1に示す様に、金属製被加熱部材(2)には、その幅方向の略中央に且つ長さ方向に沿って多数の小孔(3)が設けられる。上記の様に特定の位置に小孔(3)が設けられた金属製被加熱部材(2)においては、誘導加熱のための磁力線を照射した場合、当該金属製被加熱部材に発生する誘導電流(うず電流)を各小孔(3)の周囲に集中させることが出来る。   In the present invention, in order to uniformly heat each metal heated member (2) on the surface of the base material, as shown in FIG. A large number of small holes (3) are provided in the center and along the length direction. In the metal heated member (2) provided with the small hole (3) at a specific position as described above, when the magnetic field lines for induction heating are irradiated, the induced current generated in the metal heated member (Eddy current) can be concentrated around each small hole (3).

小孔(3)の形状は、それぞれの開口面積が略同一である限り、四角形、五角形などの多角形の他、適宜の形状に設計できるが、通常、加工性を高める観点から、図示する様な円形、または、長方形の各短辺を半円弧に形成した様な長円形に設計される。小孔(3)の大きさは、図示する様な円形の場合、直径で20mm以下の大きさ、好ましくは直径で1〜15mmの大きさとされる。   The shape of the small hole (3) can be designed to have an appropriate shape in addition to a polygon such as a quadrangle and a pentagon as long as the respective opening areas are substantially the same. It is designed to be a round shape or an oval shape in which each short side of a rectangle is formed into a semicircular arc. In the case of a circular shape as shown in the drawing, the small hole (3) has a diameter of 20 mm or less, preferably 1 to 15 mm in diameter.

小孔(3)の大きさを上記の範囲に設定する理由は次の通りである。すなわち、直径が20mmを越える場合は、小孔(3)の中央に相当する部位のホットメルト接着剤を完全に溶融できない恐れがあるので好ましくない。一方、直径が1mm未満の場合は、加工性が低下し、製造コストが上昇する。なお、小孔(3)の形状が円形以外の場合の大きさは、その開口面積に相当する面積の円形を想定し、その直径を上記の基準に照らして決定できる。   The reason for setting the size of the small hole (3) in the above range is as follows. That is, when the diameter exceeds 20 mm, the hot melt adhesive at the portion corresponding to the center of the small hole (3) may not be completely melted, which is not preferable. On the other hand, when the diameter is less than 1 mm, the workability is lowered and the manufacturing cost is increased. The size of the small hole (3) when the shape is other than a circle can be determined by assuming a circle having an area corresponding to the opening area and the diameter in light of the above criteria.

上記の小孔(3)は、電磁誘導加熱によって金属製被加熱部材(2)を均一に加熱するため、金属製被加熱部材(2)に対し、幅方向の略中央であって且つ長さに沿って一定の配列ピッチで設けられていることが重要である。そして、金属製被加熱部材(2)の全体をより一層均一に加熱するには、図2に示す様に、小孔(3)の配列ピッチ(各小孔の中心間の距離)(L)が金属製被加熱部材の幅(W)以下となる様に設定される。すなわち、図2において、L≦Wの関係を満たす様に小孔(3)が設けられる。上記の様に特定の関係を満たす様に小孔(3)を配列した場合には、各小孔(3)間において加熱されない部位が生じるのを防止でき、幅方向および長さ方向に亘って金属製被加熱部材(2)を均一に加熱できる。   The small hole (3) is substantially the center in the width direction and is long with respect to the metal heated member (2) in order to uniformly heat the metal heated member (2) by electromagnetic induction heating. It is important that they are provided at a constant arrangement pitch along. And in order to heat the whole metal to-be-heated member (2) more uniformly, as shown in FIG. 2, the arrangement pitch of the small holes (3) (distance between the centers of the small holes) (L) Is set to be equal to or less than the width (W) of the metal heated member. That is, in FIG. 2, a small hole (3) is provided so as to satisfy the relationship of L ≦ W. When the small holes (3) are arranged so as to satisfy the specific relationship as described above, it is possible to prevent a portion not heated between the small holes (3) from being generated, and to extend in the width direction and the length direction. The metal heated member (2) can be heated uniformly.

次に、上記の床下地材(1)を使用した本発明に係るフローリングの施工方法について説明する。本発明の施工方法では、先ず、一般的な従来の下地材と同様に、根太などの横架材を含む床組の上に、釘などの固定材を使用して下地材(1)を貼設する。次いで、図4に示す様に、床下地材(1)の表面にフローリング(4)を配置する。その際、床下地材(1)に対し、金属製被加熱部材(2)の長さ方向とフローリング(4)の長さ方向とが直交する様にフローリング(4)を配置する。   Next, the flooring construction method according to the present invention using the floor base material (1) will be described. In the construction method of the present invention, first, a base material (1) is pasted on a floor set including a horizontal member such as a joist using a fixing material such as a nail, like a general conventional base material. Set up. Next, as shown in FIG. 4, the flooring (4) is disposed on the surface of the floor base material (1). At that time, the flooring (4) is arranged so that the length direction of the metal heated member (2) and the length direction of the flooring (4) are orthogonal to the floor base material (1).

また、上記の様にフローリング(4)を配置すると共に、フローリング(4)の表面の金属製被加熱部材(2)に相当する部位に磁力線を照射して金属製被加熱部材(2)を誘導加熱し、金属製被加熱部材(2)表面のホットメルト接着剤を溶融することにより、床下地材(1)にフローリング(4)を接着する。具体的には、フローリング(4)の接着作業においては、フローリング(4)表面の金属製被加熱部材(2)に相当する位置に電磁誘導加熱装置(5)の加熱コイル装置(52)を押し当て、加熱コイル装置(52)に発生した磁力線によって金属製被加熱部材(2)を電磁誘導加熱し、その表面のホットメルト接着剤を溶融させてフローリング(4)を貼り付ける。   In addition, the flooring (4) is disposed as described above, and the metal heated member (2) is induced by irradiating the magnetic field lines on the surface of the flooring (4) corresponding to the metal heated member (2). The flooring (4) is bonded to the floor base material (1) by heating and melting the hot melt adhesive on the surface of the metal heated member (2). Specifically, in the bonding work of the flooring (4), the heating coil device (52) of the electromagnetic induction heating device (5) is pushed to a position corresponding to the metal heated member (2) on the surface of the flooring (4). The metal heated member (2) is electromagnetically heated by the magnetic field lines generated in the heating coil device (52), the hot melt adhesive on the surface thereof is melted, and the flooring (4) is attached.

上記の加熱操作に使用される電磁誘導加熱装置(5)は、基本的な回路構成は特開2000−220288号公報などに開示されている様に公知であり、磁力線を発生させる電源ユニット、発振制御回路、増幅器などを含む高周波発生器としての電磁誘導加熱装置本体(51)と、内部にコイルが設けられた磁界発生器としての加熱コイル装置(52)とを高周波電力供給用のケーブル(53)で接続して構成される。そして、加熱コイル装置(52)のコイルを導電性材料に近接させると共に、電磁誘導加熱装置本体(51)から加熱コイル装置(52)に高周波電力を供給し、コイルに発生させた磁力線(交番磁界)を導電性材料に透過させることにより、導電性材料に誘導電流を発生させて当該導電性材料を発熱させる様になされている。   The electromagnetic induction heating device (5) used for the above heating operation is known as the basic circuit configuration disclosed in Japanese Patent Application Laid-Open No. 2000-220288, etc. An electromagnetic induction heating device main body (51) as a high frequency generator including a control circuit, an amplifier and the like, and a heating coil device (52) as a magnetic field generator provided with a coil therein are connected to a high frequency power supply cable (53 ) And connected. And while making the coil of a heating coil apparatus (52) adjoin to an electroconductive material, high frequency power is supplied to a heating coil apparatus (52) from an electromagnetic induction heating apparatus main body (51), and the magnetic force line (alternating magnetic field) which generate | occur | produced in the coil ) Through the conductive material, an induced current is generated in the conductive material to cause the conductive material to generate heat.

また、上記の電磁誘導加熱装置(5)は、フローリング(4)の貼付け施工をより効率的に行うため、図示する様な架台(6)に搭載されていてもよい。例えば、架台(6)は、2段の棚状に組み立てられた枠組構造体であり、下段の棚板部分に電磁誘導加熱装置本体(51)を載せる様になされている。架台(4)に電磁誘導加熱装置(5)を搭載した場合には、ホットメルト接着剤を硬化させる際にフローリング(4)を押え付けるための荷重手段としても利用できる。なお、架台(6)は、上段が天板により平坦面に形成され、フローリング(4)に対する荷重が足りない場合には別途に錘を積載可能に構成されていてもよい。   The electromagnetic induction heating device (5) may be mounted on a gantry (6) as shown in order to more efficiently apply the flooring (4). For example, the gantry (6) is a frame structure assembled in a two-stage shelf shape, and is configured such that the electromagnetic induction heating device main body (51) is placed on a lower shelf plate portion. When the electromagnetic induction heating device (5) is mounted on the gantry (4), it can be used as a load means for pressing the flooring (4) when the hot melt adhesive is cured. Note that the gantry (6) may be configured such that an upper stage is formed on a flat surface by a top plate and a weight can be separately loaded when the load on the flooring (4) is insufficient.

上記の様に金属製被加熱部材(2)表面のホットメルト接着剤を溶融させた後は、溶融したホットメルト接着剤に相当する部位を上記の架台(6)等によりフローリング(4)の表面から押え付けた状態において、ホットメルト接着剤を硬化させることにより、床下地材(1)にフローリング(4)を接着することが出来る。上記の架台(6)を利用した場合は、ホットメルト接着剤を硬化させる間、次に処理すべきホットメルト接着剤の溶融作業を行うことが出来、一層効率的である。そして、フローリング(4)の長さ方向に沿って各金属製被加熱部材(2)表面のホットメルト接着剤を加熱溶融して硬化させる上記の様な作業を順次に繰り返すことにより、居室の床全体にフローリング(4)を敷設することが出来る。   After the hot-melt adhesive on the surface of the metal heated member (2) is melted as described above, the portion corresponding to the melted hot-melt adhesive is placed on the surface of the flooring (4) by the above-described gantry (6) or the like. The flooring (4) can be bonded to the floor base material (1) by curing the hot melt adhesive in a state where the floor is pressed. When the above gantry (6) is used, the hot melt adhesive to be processed next can be melted while the hot melt adhesive is cured, which is more efficient. Then, by repeating the above-described operation for heating and melting the hot-melt adhesive on the surface of each metal heated member (2) along the length direction of the flooring (4), the floor of the living room is repeated. Flooring (4) can be laid throughout.

本発明は、小孔の開いた導電性材料に磁力線を照射した場合に小孔の周囲に誘導電流が集中して発生する現象を利用したものであり、上述した様に、本発明の床下地材(1)は、基材表面に配置された帯状の金属製被加熱部材(2)に対し、その幅方向の略中央に且つ長さ方向に沿って多数の小孔(3)が設けられているため、電磁誘導によって金属製被加熱部材(2)に生じる誘導電流を各小孔(3)の周囲に集中させることが出来、床下地材(1)に対するフローリング(4)の不陸状態にさほど影響されることなく、金属製被加熱部材(2)の全体に亘って略均一に加熱することが出来る。従って、本発明の床下地材(1)及び当該床下地材を使用した施工方法によれば、金属製被加熱部材(2)表面のホットメルト接着剤を略均等に溶融させることが出来、より短時間で確実にフローリングを接着でき、そして、再施工などの必要がないため、一層効率的にフローリングを敷設できる。   The present invention utilizes a phenomenon in which induced currents are concentrated around a small hole when a magnetic field is irradiated on a conductive material having a small hole. The material (1) is provided with a large number of small holes (3) along the length direction at the approximate center in the width direction with respect to the band-shaped metal heated member (2) disposed on the surface of the base material. Therefore, the induction current generated in the metal heated member (2) by electromagnetic induction can be concentrated around each small hole (3), and the flooring (4) is not flat against the floor base material (1). It is possible to heat the metal heated member (2) substantially uniformly without being greatly affected by it. Therefore, according to the floor base material (1) of the present invention and the construction method using the floor base material, the hot-melt adhesive on the surface of the metal heated member (2) can be melted substantially evenly. The flooring can be securely bonded in a short time, and the flooring can be laid more efficiently because there is no need for re-construction.

因に、幅50mm、厚さ1mmで且つ表面にホットメルト接着剤が貼付された金属製被加熱部材(2)を予め配置して成る床下地材(1)に対し、厚さ5.5mmのフローリング(4)を重ね、電磁誘導加熱によりホットメルト接着剤を溶融させた後、ホットメルト接着剤の硬化前に直ちにフローリング(4)を剥がし、金属製被加熱部材(2)表面におけるホットメルト接着剤の溶融状態を確認した。金属製被加熱部材(2)は、直径5mmの円形の小孔(3)が35mmの配列ピッチで設けられたものと、小孔(3)が設けられていないものとを2本平行に配置し、電磁誘導加熱においては、加熱出力1100Wの電磁誘導加熱装置(5)を使用し、2本の金属製被加熱部材(2)とも各々6秒づつ磁力線を照射した。その結果、小孔(3)のない金属製被加熱部材(2)においては、ホットメルト接着剤の溶融部分が不連続であったのに対し、小孔(3)が設けられた金属製被加熱部材(2)においては、ホットメルト接着剤の溶融部分が各小孔(3)を中心に拡がり且つ金属製被加熱部材(2)の長さ方向に連続して金属製被加熱部材(2)の全面に及んでいたのが確認された。   Incidentally, the thickness of 5.5 mm with respect to the floor base material (1) in which the metal heated member (2) having a width of 50 mm and a thickness of 1 mm and having a hot melt adhesive applied to the surface is arranged in advance. After the flooring (4) is stacked and the hot melt adhesive is melted by electromagnetic induction heating, the flooring (4) is immediately peeled off before the hot melt adhesive is cured, and the hot melt adhesion on the surface of the metal heated member (2) is performed. The molten state of the agent was confirmed. In the metal heated member (2), two circular holes (3) having a diameter of 5 mm are provided in parallel with an arrangement pitch of 35 mm, and those having no small holes (3) are arranged in parallel. In the electromagnetic induction heating, an electromagnetic induction heating device (5) having a heating output of 1100 W was used, and the two metal heated members (2) were each irradiated with magnetic field lines every 6 seconds. As a result, in the metal heated member (2) without the small holes (3), the melted portion of the hot melt adhesive was discontinuous, whereas the metal coated member with the small holes (3) was provided. In the heating member (2), the melted portion of the hot melt adhesive spreads around each small hole (3) and continuously in the length direction of the metal heated member (2). ) Was confirmed to cover the entire surface.
