Description

本発明は、建築物の鉄筋コンクリート造型枠材兼用断熱パネルや、内外装下地パネル、木構造の耐力壁兼用断熱パネル、床材、間仕切り、ドア、天井用パネル、屋根下地パネルなどに好適な断熱パネルに関するものである。   The present invention is a heat insulating panel suitable for use as a reinforced concrete frame material combined heat insulating panel for buildings, an interior / exterior ground panel, a wooden structure bearing wall combined heat insulating panel, a flooring, a partition, a door, a ceiling panel, a roof base panel, etc. It is about.

従来の断熱パネルは、素材がウレタンフォーム、押出し発泡ポリスチレンボード、発泡ポリフエノール樹脂などを芯材として、それに表面材を貼付した構造のものが多く、内外壁の断熱パネルや、間仕切り、ドア、天井用パネル等に使用されている。しかしながら、このような発泡樹脂を用いた断熱パネルは、断熱性に優れている反面、構造用材としては強度が低く、また可燃性であるため、建築物等に使用した場合は火災防止の観点から、消防法によって建築物の敷地面積や建築地域が規制される場合もあり、また使用する部位や範囲も限定される問題があった。 Many conventional thermal insulation panels are made of polyurethane foam, extruded polystyrene board, foamed polyphenol resin, etc. as a core material, and a surface material is affixed to them. The insulation panels on the inner and outer walls, partitions, doors, ceilings Used for panels. However, the heat insulation panel using such a foamed resin is excellent in heat insulation, but it has low strength as a structural material and is flammable, so when used for buildings, etc., from the viewpoint of fire prevention. In some cases, there are cases where the site area or building area of a building is regulated by the Fire Service Act, and the parts and range to be used are limited.

このため、上記規制を受ける場所では防火、耐火性を考慮して樹脂フォームに難燃材を添加した断熱パネルや、押出し発泡ポリスチレンボードの両面に石膏ボードを貼付した断熱パネル、あるいはイソシアヌレートフォームを芯材として、この表面に不燃紙などを貼付した断熱パネルが使用されているが、これらは防火耐火性が未だ充分ではなく、さまざまな消火設備の設置が必要とされている。 For this reason, in places subject to the above regulations, a heat insulating panel in which a flame retardant is added to a resin foam in consideration of fire prevention and fire resistance, a heat insulating panel in which a plasterboard is pasted on both sides of an extruded foamed polystyrene board, or an isocyanurate foam are used. Thermal insulation panels with non-combustible paper attached to the surface are used as the core material, but these are still not fireproof and fireproof, and it is necessary to install various fire extinguishing equipment.

また、樹脂フォームとして最も不燃性が高いものにフェノール樹脂フォームが知られているが、単独では芯材としての強度が劣り表面材との接着性も低いため、フェノール樹脂フォーム単独では断熱パネルの芯材としては利用できないという欠点を有している。 In addition, phenol resin foams are known as the most non-flammable resin foams. However, since the strength of the core material is poor and the adhesiveness to the surface material is low by itself, the phenol resin foam alone has the core of the heat insulation panel. It has the disadvantage that it cannot be used as a material.

この欠点を解消する手段として、断熱パネル等の芯材としてフェノール樹脂フォームとハニカム体との複合体を用いたものが開示されている（例えば特許文献１）。 As means for solving this drawback, there has been disclosed one using a composite of a phenol resin foam and a honeycomb body as a core material for a heat insulating panel or the like (for example, Patent Document 1).

しかしながら、この構造の断熱パネルは、パネル芯材と表面材との剥離強度がウレタンフォームの剥離強度と同等程度であり、また一般建築物にパネルだけで自立させて用いられる耐力外壁用パネルの圧縮強度、引張り強度、曲げ強度、剥離強度が充分得られない。また芯材としてハニカム体が組込まれているため、湾曲させることができず、建築物の曲面加工した外壁を形成することができないなどの問題があった。
特開平８−８２０２１号公報 However, the heat insulation panel with this structure has a peel strength between the panel core and the surface material that is comparable to the peel strength of urethane foam, and is a compression of a load-bearing outer wall panel that is used alone in a general building. Strength, tensile strength, bending strength, and peel strength cannot be obtained sufficiently. In addition, since the honeycomb body is incorporated as the core material, there is a problem that it cannot be curved and an outer wall obtained by processing a curved surface of a building cannot be formed.
JP-A-8-82021

以下本発明の断熱パネルについて図面を参照して説明する。図１は断熱パネル１を示すもので、芯材２に波形金属板３を用い、両面を硬質発泡樹脂フォーム４により積層し、熱硬化性樹脂５を含浸させて表面を発泡硬化させた無機質繊維シート６を、前記両硬質発泡樹脂フォーム４の表面に積層し、更にその表面にシート状の表面材７を貼付して一体化したものである。 The heat insulating panel of the present invention will be described below with reference to the drawings. FIG. 1 shows a heat insulating panel 1, an inorganic fiber using a corrugated metal plate 3 as a core material 2, laminated on both sides with a hard foamed resin foam 4, impregnated with a thermosetting resin 5 and foam-cured on the surface. A sheet 6 is laminated on the surfaces of the both hard foamed resin foams 4 and a sheet-like surface material 7 is stuck on the surface and integrated.

前記芯材２となる波形金属板３は波形の形状を有する金属板であれば何れのもでも良く、経済性の面から波形鋼板が望ましい。この波形金属板３は例えば図２に示すように、孔８を多数開孔した有孔の波形金属板３でも良い。この場合、加工する孔８の形状は円形が望ましいが、その他の形状でも良く、また孔の割合は強度が著しく低下しない程度が良い。また孔８の直径は１０ｍｍ程度のものをランダム加工したものが良い。 The corrugated metal plate 3 as the core material 2 may be any corrugated metal plate, and is preferably a corrugated steel plate from the viewpoint of economy. For example, as shown in FIG. 2, the corrugated metal plate 3 may be a perforated corrugated metal plate 3 having a large number of holes 8. In this case, the shape of the hole 8 to be processed is preferably a circular shape, but may be other shapes, and the ratio of the holes should be such that the strength is not significantly reduced. Further, the hole 8 preferably has a diameter of about 10 mm processed randomly.

また芯材２となる波形金属板３の両面に積層する硬質発泡樹脂フォーム４は、例えば硬質発泡ウレタン樹脂や硬質発泡フェノール樹脂フォーム、硬質発泡ポリスチレン樹脂フォーム、などの、発泡した硬質の樹脂であれば良い。また硬質発泡樹脂フォーム４の表面に積層する無機質繊維シート６としては、例えばグラスウールやロックウールなどの耐熱性の繊維シートを用いる。この無機質繊維シート６は、硬質発泡樹脂フォーム４を担持するだけでなく硬質発泡樹脂フォーム４や熱硬化性樹脂フォーム５が発泡する際に発生する発泡時の余剰な分解ガスを外へ逃がすための流路としての役割も果たす。 The rigid foamed resin foam 4 laminated on both surfaces of the corrugated metal plate 3 as the core material 2 may be a foamed rigid resin such as a rigid foamed urethane resin, a rigid foamed phenol resin foam, a rigid foamed polystyrene resin foam, or the like. It ’s fine. Moreover, as the inorganic fiber sheet 6 laminated | stacked on the surface of the hard foamed resin foam 4, heat resistant fiber sheets, such as glass wool and rock wool, are used, for example. This inorganic fiber sheet 6 not only carries the hard foamed resin foam 4 but also releases the excessive decomposition gas at the time of foaming generated when the hard foamed resin foam 4 and the thermosetting resin foam 5 foam. Also serves as a flow path.

またこの無機質繊維シート６の表面に含浸して発泡硬化させた熱硬化性樹脂フォーム５としては、接着性を有する例えば低発泡樹脂フォームが好ましい。この熱硬化性樹脂フォーム５は、液状の熱硬化性樹脂５Ａを塗布するか、あるいは粉体を散布して、これを加熱することにより液状化して無機質繊維シート６の表面から含浸して発泡することにより形成する。この熱硬化性樹脂フォーム５は、無機質繊維シート６に絡みながらここを貫通して硬質発泡樹脂フォーム４の表面に食い込むような形で発泡硬化しているので、釘やビスを取付ける場合に、確実に固定できるアンカー効果を生じる。 The thermosetting resin foam 5 impregnated on the surface of the inorganic fiber sheet 6 and foam-cured is preferably a low-foamed resin foam having adhesiveness. The thermosetting resin foam 5 is liquefied by applying a liquid thermosetting resin 5A or by spraying powder and heating it to impregnate from the surface of the inorganic fiber sheet 6 and foam. To form. This thermosetting resin foam 5 is foam-cured in such a way that it penetrates the inorganic fiber sheet 6 while penetrating the inorganic fiber sheet 6 and bites into the surface of the hard foamed resin foam 4, so that it is reliable when attaching nails and screws. This produces an anchor effect that can be fixed to.

このアンカー効果は、熱硬化性樹脂フォーム５の厚さが１ｍｍ以上あれば十分である。１ｍｍ未満では、アンカー効果が不十分で釘やビスが固定できない恐れがある。また断熱パネル全体の厚さに対する無機質繊維シート６の厚さの割合は、強度、断熱性とのバランスを考慮すると２〜１３％の範囲が好ましい。 The anchor effect is sufficient if the thickness of the thermosetting resin foam 5 is 1 mm or more. If it is less than 1 mm, the anchor effect is insufficient and the nail or screw may not be fixed. Moreover, the ratio of the thickness of the inorganic fiber sheet 6 with respect to the thickness of the whole heat insulation panel has the preferable range of 2 to 13% when the balance with intensity | strength and heat insulation is considered.

また熱硬化性樹脂フォーム５の表面に貼付するシート状の表面材７としては、例えば不燃紙や化粧紙などの紙類の他、アルミニュウム板やメッキ鋼板、着色した鋼板などの金属板、あるいは、壁クロスや天井クロス、フローリングクロスなど、模様を印刷した紙や布、合成樹脂などのシートを用いることができる。表面材として不燃紙や金属板を用いれば、防火、耐火性を向上させることができる。また表面材として金属板や、化粧紙を用いれば、鉄筋コンクリート造型枠用の残置型枠として、そのまま使用しても建物の外観塗装の必要がなく、工場での生産が可能である。また建築物の外壁面形成用の残置型枠として用いる表面材に、酸化チタンを塗布または含浸させれば、その還元作用により表面が清浄化され外観を長期間に亘って良好に保持することができる。 Further, as the sheet-like surface material 7 to be attached to the surface of the thermosetting resin foam 5, for example, paper such as non-combustible paper or decorative paper, an aluminum plate, a plated steel plate, a metal plate such as a colored steel plate, or Sheets such as wall cloth, ceiling cloth, flooring cloth, printed paper, cloth, and synthetic resin can be used. If nonflammable paper or a metal plate is used as the surface material, fire resistance and fire resistance can be improved. Further, if a metal plate or decorative paper is used as the surface material, it can be used as it is as a remaining mold for a reinforced concrete frame, and it is not necessary to paint the exterior of the building and can be produced in a factory. In addition, if titanium oxide is applied or impregnated on a surface material used as a remaining mold for forming the outer wall surface of a building, the surface can be cleaned by the reduction action and the appearance can be maintained well over a long period of time. it can.

また本発明の断熱パネル１の厚さは特に限定されないが外壁用など、強度や防火・耐火性が必要とされる用途に使用する場合には、全体の厚さが４０ｍｍ以上が好ましく、また床材、間仕切り、ドア、天井用パネル、屋根下地パネルとして用いる場合には３０ｍｍ程度の厚さで十分である。なお本発明では図３に示すように波形金属板３として孔８のない波形金属板３を用いても良い。また波形金属板３は１枚に限らず、複数枚設けて更に強度を向上させて構造でも良い。この場合、２枚の波形金属板３、３の間に硬質発泡樹脂フォームを介在させても良い Further, the thickness of the heat insulating panel 1 of the present invention is not particularly limited, but when used for an application such as an outer wall where strength, fire resistance and fire resistance are required, the total thickness is preferably 40 mm or more. When used as a material, partition, door, ceiling panel, roof base panel, a thickness of about 30 mm is sufficient. In the present invention, a corrugated metal plate 3 without holes 8 may be used as the corrugated metal plate 3 as shown in FIG. Further, the corrugated metal plate 3 is not limited to one, and a plurality of corrugated metal plates 3 may be provided to further improve the strength. In this case, a rigid foamed resin foam may be interposed between the two corrugated metal plates 3 and 3.

次に本発明の断熱パネル１の製造方法について説明する。図４に示すように、先ずシート状の表面材７の上に液状の熱硬化性樹脂５Ａを塗布するか粉体を散布する。次にこの上に無機質繊維シート６を重ねてから硬質発泡樹脂４Ａの粉体を重ね、更にこの上に有孔の波形金属板３を重ねて下部積層体を形成する。次に同様の工程で上部積層体を形成して、これを下部積層体の上に重ねて積層体９を形成する。 Next, the manufacturing method of the heat insulation panel 1 of this invention is demonstrated. As shown in FIG. 4, first, a liquid thermosetting resin 5A is applied on a sheet-like surface material 7 or powder is dispersed. Next, the inorganic fiber sheet 6 is overlaid thereon, the powder of the hard foamed resin 4A is overlaid, and the perforated corrugated metal plate 3 is overlaid thereon to form the lower laminate. Next, an upper laminated body is formed in the same process, and this is laminated on the lower laminated body to form the laminated body 9.

次にこの積層体９を加熱機構を備えたプレスの下型１０の上に載せ、周囲を金属製の枠状スペーサー１１で囲んでから、上型１２を被せて加熱加圧すると、硬質発泡樹脂４Ａと熱硬化性樹脂５Ａが発泡して、図１に示すように波形金属板３の両面に、硬質発泡樹脂フォーム４と、表面に熱硬化性樹脂フォーム５が含浸形成された無機質繊維シート６およびシート状の表面材７が一体となった断熱パネル１が形成される。 Next, this laminated body 9 is placed on a lower die 10 of a press equipped with a heating mechanism, and the periphery is surrounded by a metal frame spacer 11, and then the upper die 12 is covered and heated and pressurized, whereby a hard foamed resin is obtained. 4A and the thermosetting resin 5A are foamed, and as shown in FIG. 1, an inorganic fiber sheet 6 in which a hard foam resin foam 4 is impregnated and formed on both surfaces of a corrugated metal plate 3 and a thermosetting resin foam 5 is impregnated on the surface. And the heat insulation panel 1 with which the sheet-like surface material 7 was united is formed.

上記構成の断熱パネル１は図１に示すように、芯材２に波形金属板３を用い、この両側に硬質発泡樹脂フォーム４が設けられ、更にその外側に断熱性に優れた無機質繊維シート６が積層され、この表面に熱硬化性樹脂５Ａを含浸させて発泡硬化させた熱硬化性樹脂フォーム５が形成されているので、圧縮、引張、曲げ、剥離強度など強度が高く、しかも断熱性に優れている。また断熱パネル１は内部に余剰な分解ガス等が残留していないので、硬質発泡樹脂フォーム４が完全に且つ均一に発泡充填されているので強度が高い。また芯材２として有孔の波形金属板３を使用したものは、この両側の硬質発泡樹脂フォーム４が孔８を通して一体に形成されているので剥離強度が高い。 As shown in FIG. 1, the heat insulating panel 1 having the above configuration uses a corrugated metal plate 3 as a core material 2, a hard foamed resin foam 4 is provided on both sides thereof, and an inorganic fiber sheet 6 having excellent heat insulating properties on the outside thereof. Since the thermosetting resin foam 5 is formed by impregnating the surface with the thermosetting resin 5A and foamed and cured, it has high strength such as compression, tension, bending, and peeling strength, and is also heat insulating. Are better. Moreover, since the excessive decomposition gas etc. do not remain inside the heat insulation panel 1, the strength is high because the hard foamed resin foam 4 is completely and uniformly foam-filled. Also, the one using the perforated corrugated metal plate 3 as the core material 2 has high peel strength because the hard foamed resin foam 4 on both sides is integrally formed through the holes 8.

また本発明の断熱パネル１は芯材２に波形金属板３を使用しているので曲面加工も容易である。この場合、図５に示すように断熱パネル１の両面に所定の間隔でスリット１３を表面に対して垂直に入れる。この場合、外周側には線状のスリット１３を、内周側には逆Ｖ形状のスリット１３を予め入れておき、これを曲げることにより図６に示すように湾曲させて、曲面を形成することができる。このため残置型枠として、使用後に躯体に残置する鉄筋コンクリート造型枠材として用いると、容易に曲面加工したコンクリート壁面を形成することができる。またコンクリート壁面の両側が断熱材で被覆された状態となっているので、室内の結露を防止する効果も得ることができる。 Moreover, since the heat insulation panel 1 of this invention uses the corrugated metal plate 3 for the core material 2, curved surface processing is also easy. In this case, as shown in FIG. 5, slits 13 are vertically inserted on the both surfaces of the heat insulating panel 1 at a predetermined interval. In this case, a linear slit 13 is put on the outer peripheral side, and an inverted V-shaped slit 13 is put on the inner peripheral side in advance, and this is bent to form a curved surface as shown in FIG. be able to. For this reason, if it uses as a reinforced concrete formwork frame material left to a housing after use as a leaving mold, the concrete wall surface which carried out curve processing can be formed easily. In addition, since both sides of the concrete wall are covered with a heat insulating material, the effect of preventing indoor dew condensation can be obtained.

このため本発明の断熱パネル１を使用後に躯体に残置する鉄筋コンクリート造型枠材兼用断熱パネルや、内外装下地パネル、木構造の耐力壁兼用断熱パネル、床材、間仕切り、ドア、天井用パネル、屋根下地パネルなど多機能の目的に使用することができる。 For this reason, the reinforced concrete frame material combined heat insulation panel, the interior / exterior base panel, the wooden structure bearing wall combined heat insulation panel, the flooring, the partition, the door, the ceiling panel, the roof, which are left in the frame after using the heat insulation panel 1 of the present invention It can be used for multifunctional purposes such as a base panel.

シート状の表面材７として不燃紙を用い、この上に熱硬化性樹脂５Ａとして低発泡ウレタン樹脂液を塗布し、この上に無機質繊維シート６としてガラスチョップドストランドマットを単位面積重量が３００ｇ／ｍ２を重ね、この上に硬質発泡樹脂４Ａの粉体を単位面積当りの散布量が１０００ｇ／ｍ２となるように重ねてから波形金属板３として有孔の波形鋼板を重ねて下部積層体を形成する。次に同様の工程で上部積層体を形成して、これを下部積層体の上に重ねて積層体９を形成する。 Non-combustible paper is used as the sheet-like surface material 7, a low-foaming urethane resin liquid is applied thereon as the thermosetting resin 5 A, and a glass chopped strand mat is formed thereon as the inorganic fiber sheet 6 with a unit area weight of 300 g / m. 2 are stacked, and the powder of the hard foamed resin 4A is stacked thereon so that the spraying amount per unit area is 1000 g / m 2, and then the perforated corrugated steel plate is stacked as the corrugated metal plate 3 to form the lower laminate. Form. Next, an upper laminated body is formed in the same process, and this is laminated on the lower laminated body to form the laminated body 9.

次にこの積層体９を加熱機構を備えたプレスの下型１０の上に載せ、周囲を高さ５５ｍｍのアルミニウム製の枠状スペーサー１１で囲んでから、上型１２を被せて１７０℃で１０分間加熱加圧して図１に示す断熱パネル１を成型した。得られた断熱パネル１について表１に示す試験を行ない、その結果を表２に示した。また比較のために前記特許文献１に挙げた特開平８−８２０２号公報に記載の実施例を比較例として、表２に併記した。 Next, this laminated body 9 is placed on a lower mold 10 of a press equipped with a heating mechanism, and the periphery is surrounded by a frame spacer 11 made of aluminum having a height of 55 mm. A heat insulating panel 1 shown in FIG. The obtained heat insulation panel 1 was subjected to the tests shown in Table 1, and the results are shown in Table 2. For comparison, the examples described in JP-A-8-8202 listed in Patent Document 1 are also shown in Table 2 as comparative examples.

表２の結果から実施例の数値と比較例（特許文献１ 特開平８−８２０２号公報に記載の実施例）を比較した通り本発明の数値の方がはるかに高く多機能の断熱パネルとして汎用性が確認された。 From the results of Table 2, the numerical values of the present invention are much higher as compared with the numerical values of the examples and the comparative examples (examples described in Japanese Patent Laid-Open No. 8-8202), and are generally used as multifunctional heat insulation panels. Sex was confirmed.
