Abstract

[Problem] To improve the connection strength in a folded portion formed by folding a portion of a resin plate. [Solution] This resin plate comprises a resin plate body, a fold formed in the plate body, and a folded portion formed by folding a portion of the plate body along the fold. The fold comprises a high-density portion and a low-density portion, and the high-density portion and the low-density portion are disposed alternately in the direction in which the fold extends. In addition, the high-density portion is formed so that the prescribed unit density is higher than the density in portions outside of the fold, and the low-density portion is formed so that the prescribed unit density is lower than the density in the high-density portion.

Description

樹脂プレート及び樹脂プレートの製造方法、樹脂プレートを用いた断熱材ユニットResin plate, resin plate manufacturing method, and heat insulation unit using resin plate
　本発明は、被折曲部を有する樹脂プレートに関し、より詳細には、断熱材ユニットのガイドプレートに関する。 The present invention relates to a resin plate having a bent portion, and more particularly to a guide plate for a heat insulating material unit.
　例えば、一枚の板状プレートの一部を折り曲げて被折曲部を構成することができる。このとき、プレートに形成された折り曲げ線に沿って板状プレートの一部を折り曲げるが、折り曲げ線を介した被折曲部の連結強度が低いと、折り曲げて被折曲部を回動させているうちに破断したり、被折曲部に引っ張り力を加えると破断したりしてしまうことがある。 For example, a bent portion can be formed by bending a part of one plate-like plate. At this time, a part of the plate-like plate is bent along the fold line formed on the plate, but if the connection strength of the bent portion through the fold line is low, the bent portion is bent and rotated. It may break while it is broken, or it may break if a tensile force is applied to the bent part.

（第１実施形態）
　図１から図８は、第１実施形態を示す図である。図１は、被折曲部１１０を有する樹脂プレートの構成図である。図１に示すように、本実施形態の樹脂プレートは、樹脂製の一枚のプレート体１００で構成され、プレート体１００の一部を折り曲げ部１２０に沿って折り曲げることで、被折曲部１１０が形成される。 (First embodiment)
1 to 8 are diagrams showing a first embodiment. FIG. 1 is a configuration diagram of a resin plate having a bent portion 110. As shown in FIG. 1, the resin plate of the present embodiment is composed of a single plate body 100 made of resin, and a bent portion 110 is formed by bending a part of the plate body 100 along a bent portion 120. Is formed.
　プレート体１００は、塩化ビニル樹脂、ＰＥＴ樹脂、アクリル樹脂、ＰＰ樹脂、ポリカーボネイトなどの樹脂材で構成されている。プレート体１００は、Ｙ方向の長さがＨ１、Ｘ方向の幅がＨ２（Ｘ方向）、Ｚ方向の厚さ（板厚）がＤの矩形状に形成されている。なお、プレート体１００の形状は、矩形状など四角形に特に限らず、多角形状や円形状で構成されることも可能であるし、平板状や湾曲形状など波形板状などで構成され得る。 The plate body 100 is made of a resin material such as vinyl chloride resin, PET resin, acrylic resin, PP resin, or polycarbonate. The plate body 100 is formed in a rectangular shape having a length in the Y direction H1, a width in the X direction H2 (X direction), and a thickness (plate thickness) in the Z direction D. The shape of the plate body 100 is not particularly limited to a quadrangle such as a rectangular shape, and may be a polygonal shape or a circular shape, or may be a corrugated plate shape such as a flat plate shape or a curved shape.
　折り曲げ部１２０は、プレート体１００のＸ方向の一端から他端にかけて延設されており、折り曲げ部１２０の長さは、プレート体１００の幅Ｈ２と同じ（又は略同じ）である。また、折り曲げ部１２０は、プレート体１００のＹ方向の一端から所定距離Ｈ３、内側に位置してプレート体１００に形成されている。なお、折り曲げ部１２０の長さは、プレート体１００の幅Ｈ２よりも短く構成することも可能である。 The bent portion 120 is extended from one end to the other end of the plate body 100 in the X direction, and the length of the bent portion 120 is the same (or substantially the same) as the width H2 of the plate body 100. Further, the bent portion 120 is formed on the plate body 100 so as to be located at a predetermined distance H3 from one end of the plate body 100 in the Y direction. The length of the bent portion 120 can be configured to be shorter than the width H2 of the plate body 100.
　折り曲げ部１２０は、一枚のプレート体１００を被折曲部１１０と被折曲部１１０以外の領域に区画し、被折曲部１１０を表面１０２側に折り曲げるための折り曲げ線（具体的には、折り曲げ線は、線状であり、例えば直線状や円弧状など曲線状や波線状で構成され得る）である。つまり、折り曲げ部１２０は、プレート体１００のＸ－Ｙ平面において、表面１０１側が山、表面１０２側が谷となる折り曲げ線として形成される。ここで、折り曲げ部１２０が形成されるプレート体１００の位置（所定距離Ｈ３）は、任意に設定することができる。また、折り曲げ部１２０は、プレート体１００に一又は複数形成され得る。 The bending portion 120 divides one plate body 100 into a region other than the bent portion 110 and the bent portion 110, and a bending line (specifically, a bending line for bending the bent portion 110 to the surface 102 side). The fold line is linear, and can be configured to be curved or wavy, for example, linear or arcuate). That is, the bent portion 120 is formed as a fold line in the XY plane of the plate body 100 where the surface 101 side is a peak and the surface 102 side is a valley. Here, the position (predetermined distance H3) of the plate body 100 where the bent part 120 is formed can be arbitrarily set. Further, one or a plurality of bent portions 120 may be formed on the plate body 100.
　被折曲部１１０は、折り曲げ部１２０を連結部として折り曲げ自在に回動することができる。図２は、プレート体１００の一部を折り曲げて形成された被折曲部１１０の態様を示す図である。図２に示すように、被折曲部１１０は、プレート体１００の表面１０２を内側として折り曲げることができ、フラットな状態（Ｙ方向と水平な状態、例えば、０度）から屈曲させた状態（Ｚ方向と水平な状態、例えば、９０度）までの範囲で、折り曲げ自在に回動させることができる。 The bent portion 110 can be bent so that the bent portion 120 can be bent. FIG. 2 is a diagram showing an aspect of the bent portion 110 formed by bending a part of the plate body 100. As shown in FIG. 2, the bent portion 110 can be bent with the surface 102 of the plate body 100 as an inner side, and is bent from a flat state (a state parallel to the Y direction, for example, 0 degrees) ( It can be freely bent and rotated within a range up to 90 degrees (for example, 90 degrees) with respect to the Z direction.
　図３は、本実施形態の折り曲げ部１２０のＸ－Ｚ断面図である。折り曲げ部１２０は、高密度部１２１と低密度部１２２とを含んで構成されており、高密度部１２１と低密度部１２２とが折り曲げ部１２０が延びる方向（Ｘ方向）において交互に複数並んで配置されている。図３の例で示す折り曲げ部１２０は、例えば、プレス加工（例えば熱圧加工を含む）で形成することができる。 FIG. 3 is an XZ sectional view of the bent portion 120 of the present embodiment. The bent portion 120 includes a high density portion 121 and a low density portion 122, and a plurality of high density portions 121 and low density portions 122 are alternately arranged in the direction (X direction) in which the bent portion 120 extends. Has been placed. The bending part 120 shown in the example of FIG. 3 can be formed by, for example, pressing (including hot pressing).
　高密度部１２１は、プレート体１００の表面１０１から凹んだ深さｄ１を有する凹部である。また、低密度部１２２は、プレート体１００の表面１０１から凹んだ深さｄ１よりも深い深さｄ２を有する凹部である。ここで、図３の例では、低密度部１２２は、表面１０１から表面１０２まで貫通する切り欠き部として形成されている。したがって、図３の低密度部１２２の密度ａ１は、プレート体１００の厚さ方向の密度ｂに対して０となっており、プレス加工によって打ち抜き成形される。低密度部１２２の深さｄ２は、プレート体１００の厚さＤと同じとなっている。 The high density portion 121 is a recess having a depth d1 that is recessed from the surface 101 of the plate body 100. The low density portion 122 is a recess having a depth d2 that is deeper than the depth d1 that is recessed from the surface 101 of the plate body 100. Here, in the example of FIG. 3, the low density portion 122 is formed as a cutout portion penetrating from the surface 101 to the surface 102. Therefore, the density a1 of the low density portion 122 in FIG. 3 is 0 with respect to the density b in the thickness direction of the plate body 100, and is stamped and formed by pressing. The depth d2 of the low density portion 122 is the same as the thickness D of the plate body 100.
　一方、高密度部１２１は、プレス加工によって表面１０１からＺ方向に深さｄ１圧縮されて形成される。高密度部１２１の所定単位当たり（例えば、単位体積あたり）の密度ａが折り曲げ部１２０以外の密度、例えば、折り曲げ部１２０が形成されないプレート体１００の密度ｂよりも高く形成されている。 On the other hand, the high density portion 121 is formed by being compressed by the depth d1 from the surface 101 in the Z direction by pressing. The density a per predetermined unit (for example, per unit volume) of the high-density portion 121 is higher than the density other than the bent portion 120, for example, the density b of the plate body 100 where the bent portion 120 is not formed.
　図３に示す高密度部１２１の他の成形例として、例えば、切削加工により高密度部１２１に対応する領域を表面１０１から深さｄ１未満の所定深さまで切削し、その後プレス加工で高密度部１２１に対応する領域を深さｄ１まで圧縮することができる。 As another molding example of the high density portion 121 shown in FIG. 3, for example, a region corresponding to the high density portion 121 is cut from the surface 101 to a predetermined depth less than the depth d1 by cutting, and then the high density portion is pressed. The region corresponding to 121 can be compressed to a depth d1.
　次に、図４は、折り曲げ部１２０の変形例を示す図であり、図３の例に対して低密度部１２２がプレート体１００の厚さ方向に貫通していない態様を示している。図４に示すように、低密度部１２２は、表面１０１から深さｄ３を有する凹部として形成されている。このとき、低密度部１２２は、低密度部１２２に対応する領域を表面１０１から深さｄ３で切削して形成することができる。 Next, FIG. 4 is a view showing a modified example of the bent portion 120, and shows a mode in which the low density portion 122 does not penetrate in the thickness direction of the plate body 100 with respect to the example of FIG. 3. As shown in FIG. 4, the low density portion 122 is formed as a recess having a depth d <b> 3 from the surface 101. At this time, the low density portion 122 can be formed by cutting a region corresponding to the low density portion 122 from the surface 101 at a depth d3.
　図４の例において、高密度部１２１は、図３の例と同様に、厚さ方向に圧縮されてプレート体１００の密度ｂよりも高い密度ａに形成されるが、低密度部１２２が厚さ方向に圧縮されないように（低密度部１２２の密度ａ１がプレート体１００の密度ｂと同じに）成形したり、低密度部１２２の密度ａ１が高密度部１２１の密度ａよりも低い密度となるように厚さ方向に圧縮して成形したりすることができる。 In the example of FIG. 4, the high density portion 121 is compressed in the thickness direction and formed to a density a higher than the density b of the plate body 100 as in the example of FIG. 3, but the low density portion 122 is thick. It is molded so that it is not compressed in the vertical direction (the density a1 of the low density portion 122 is the same as the density b of the plate body 100), or the density a1 of the low density portion 122 is lower than the density a of the high density portion 121. It can be formed by being compressed in the thickness direction.
　このように本実施形態の高密度部１２１は、所定単位当たりの密度ａが折り曲げ部１２０以外の密度ｂよりも高く形成され、低密度部１２２は、所定単位当たりの密度ａ１が高密度部１２１の密度ａよりも低く形成される。低密度部の密度ａ１は、０≦ａ１＜ａの範囲となる。密度ａ１が「０」とは、貫通した状態（樹脂が存在しない状態）を示している。なお、折り曲げ部１２０は、被折曲部１１０の折り曲げ方向とは逆の表面１０１側から上述したプレス加工又は／及び切削加工が施されて形成されている。 As described above, the high density portion 121 of the present embodiment is formed such that the density a per predetermined unit is higher than the density b other than the bent portion 120, and the low density portion 122 has the density a 1 per predetermined unit of the high density portion 121. It is formed lower than the density a. The density a1 of the low density portion is in the range of 0 ≦ a1 <a. A density a1 of “0” indicates a penetrated state (a state where no resin is present). The bent portion 120 is formed by performing the above-described pressing or / and cutting from the surface 101 side opposite to the bending direction of the bent portion 110.
　そして、図３及び図４に示すように、一の高密度部１２１は、Ｘ方向に長さＡを有し、一の低密度部１２２は、Ｘ方向に長さＢを有している。複数の高密度部１２１の長さＡの合計値Ａ_ｔｏｔａｌと、複数の低密度部１２２の長さＢの合計値Ｂ_ｔｏｔａｌとの合算値が、折り曲げ部１２０のＸ方向長さＨ２となる。したがって、合計値Ａ_ｔｏｔａｌは、折り曲げ部１２０のＸ方向の全長Ｈ２に対して高密度部１２１が配置される領域であり、合計値Ｂ_ｔｏｔａｌは、折り曲げ部１２０のＸ方向の全長Ｈ２に対して低密度部１２２が配置される領域となる。 3 and 4, one high density portion 121 has a length A in the X direction, and one low density portion 122 has a length B in the X direction. The total value of the total value A_total of the lengths A of the plurality of high-density portions 121 and the total value B_total of the lengths B of the plurality of low-density portions 122 is the length H2 of the bent portion 120 in the X direction. Therefore, the total value A_total is a region where the high-density portion 121 is disposed with respect to the total length H2 of the bent portion 120 in the X direction, and the total value B_total is a low density with respect to the total length H2 of the bent portion 120 in the X direction. This is an area where the part 122 is arranged.
　図５は、折り曲げ部１２０に沿って折り曲げられる被折曲部１１０と折り曲げ部１２０を構成する高密度部１２１の変形状態を説明するための図である。図５（ａ）に示すように、被折曲部１１０を折り曲げ部１２０に沿って表面１０２側に折り曲げていない状態では、Ｙ方向における折り曲げ部１２０の幅はＰである。 FIG. 5 is a diagram for explaining a deformed state of the bent portion 110 that is bent along the bent portion 120 and the high-density portion 121 that constitutes the bent portion 120. As shown in FIG. 5A, the width of the bent portion 120 in the Y direction is P when the bent portion 110 is not bent along the bent portion 120 toward the surface 102.
　次に、図５（ｂ）に示すように、被折曲部１１０を折り曲げ部１２０に沿って表面１０２側に折り曲げると、高密度部１２１は伸長して変形する。表面１０１側における高密度部１２１は、幅Ｐよりも長くなる。また、図５（ｃ）に示すように被折曲部１１０をＹ方向に対して垂直となるまで折り曲げると、高密度部１２１はさらに伸長して変形する。表面１０１側における高密度部１２１の長さは、図５（ｂ）の長さよりもさらに長くなる。 Next, as shown in FIG. 5B, when the bent portion 110 is bent along the bent portion 120 toward the surface 102, the high-density portion 121 expands and deforms. The high density portion 121 on the surface 101 side is longer than the width P. Further, as shown in FIG. 5C, when the bent portion 110 is bent until it is perpendicular to the Y direction, the high-density portion 121 is further expanded and deformed. The length of the high density portion 121 on the surface 101 side is further longer than the length of FIG.
　本実施形態の被折曲部１１０を有する樹脂プレートは、高密度部１２１と低密度部１２２とが交互に並んで配置されることで、被折曲部１１０を折り曲げ自在に回動させ易くしつつ、高密度部１２１の密度が高いので、折り曲げ部１２０を介した被折曲部１１０の連結強度を向上させることができる。 In the resin plate having the bent portion 110 according to the present embodiment, the bent portion 110 can be bent and easily rotated by arranging the high density portions 121 and the low density portions 122 alternately. However, since the density of the high-density part 121 is high, the connection strength of the bent part 110 via the bent part 120 can be improved.
　次に、上述した本実施形態の樹脂プレートの使用例について説明する。例えば、炉などの断熱構造体の表面に配置される断熱材ユニットのガイド部材に、本実施形態の樹脂プレートを適用することができる。 Next, a usage example of the resin plate of this embodiment described above will be described. For example, the resin plate of this embodiment can be applied to a guide member of a heat insulating material unit disposed on the surface of a heat insulating structure such as a furnace.
　図６は、本実施形態の樹脂プレートを有する製品として、樹脂プレートを用いた断熱材ユニット３００の構成例を示す図である。図６に示すように、断熱材ブロック２００は、長尺状の断熱シートを幾層にも折り畳んでブロック状に成形したものである。断熱材ブロック２００の上面には、ブロック状に折り畳まれた断熱材を束ねて固定するための固定部材２０１が設けられている。 FIG. 6 is a diagram showing a configuration example of a heat insulating material unit 300 using a resin plate as a product having the resin plate of the present embodiment. As shown in FIG. 6, the heat insulating material block 200 is formed by folding a long heat insulating sheet into several layers. On the upper surface of the heat insulating material block 200, a fixing member 201 for bundling and fixing the heat insulating material folded in a block shape is provided.
　断熱材ブロック２００を構成する断熱シートは、Ｘ方向に所定の幅を有しおり、幾層にも折り畳まれた断熱材ブロック２００は、立方体又は直方体の形状に成形されている。なお、断熱シートとしては、例えば、ニチアス株式会社のセラミックファイバーブランケット、ＡＥＳブランケットなどを用いることができるが、これに限るものではない。 The heat insulating sheet constituting the heat insulating material block 200 has a predetermined width in the X direction, and the heat insulating material block 200 folded in several layers is formed into a cubic or rectangular parallelepiped shape. In addition, as a heat insulation sheet, for example, a ceramic fiber blanket, an AES blanket, etc. manufactured by NICHIAS Corporation can be used, but not limited thereto.
　被折曲部１１０を有する樹脂プレートは、断熱材ブロック２００の左右側面にそれぞれ設けられ、断熱材ブロック２００が一対の樹脂プレートで挟持されるように配置される。断熱材ブロック２００は、一対の樹脂プレートによって挟持される方向に圧縮することができる。このとき、被折曲部１１０は、樹脂プレートが当接する断熱材ブロック２００の側面から断熱材ブロック２００の当該側面に隣接する一面に向かって、すなわち、断熱材ブロック２００の側面の下端から断熱材ブロック２００の底部に向かって、延びるように折り曲げられている。 The resin plates having the bent portions 110 are provided on the left and right side surfaces of the heat insulating material block 200, respectively, and are arranged so that the heat insulating material block 200 is sandwiched between a pair of resin plates. The heat insulating material block 200 can be compressed in the direction sandwiched between the pair of resin plates. At this time, the bent portion 110 extends from the side surface of the heat insulating material block 200 with which the resin plate abuts toward one surface adjacent to the side surface of the heat insulating material block 200, that is, from the lower end of the side surface of the heat insulating material block 200. It is bent so as to extend toward the bottom of the block 200.
　断熱材ブロック２００は、一対の樹脂プレートの外側から複数の拘束バンドＫＢで周囲が拘束され、圧縮されている。Ｘ－Ｚ平面と略平行に断熱材ブロック２００及び樹脂プレートの周囲を拘束する拘束バンドＫＢと、Ｙ－Ｚ平面に略平行に断熱材ブロック２００及び樹脂プレートの周囲を拘束する拘束バンドＫＢと、が設けられている。 The periphery of the heat insulating material block 200 is constrained and compressed by a plurality of restraining bands KB from the outside of the pair of resin plates. A restraining band KB for restraining the periphery of the heat insulating material block 200 and the resin plate substantially parallel to the XZ plane; and a restraining band KB for restraining the periphery of the heat insulating material block 200 and the resin plate substantially parallel to the YZ plane; Is provided.
　本実施形態の断熱材ユニット３００は、断熱材ブロック２００と、断熱材ブロック２００を左右側面が挟み込む一対の樹脂プレートと、樹脂プレートの外側から断熱材ブロック２００を上下左右方向から圧縮する拘束バンドＫＢとを含んで構成されている。 The heat insulating material unit 300 of the present embodiment includes a heat insulating material block 200, a pair of resin plates that sandwich the heat insulating material block 200 between the left and right side surfaces, and a restraining band KB that compresses the heat insulating material block 200 from the upper, lower, left, and right directions from the outside of the resin plate. It is comprised including.
　図７は、図６に示した断熱材ユニット３００が断熱構造体に適用される一例を示す図である。断熱材ユニット３００は、例えば、断熱構造体の表面にライニングされる。断熱構造体の一例として、図７の例では、断熱構造体の表面を構成する耐火レンガＲｅ１と、耐火レンガＲｅ１を設置面として断熱材ユニット３００が配置される設置空間Ｓを形成する耐火レンガＲｅ２と、を含んで構成されている。 FIG. 7 is a diagram showing an example in which the heat insulating material unit 300 shown in FIG. 6 is applied to a heat insulating structure. The heat insulating unit 300 is lined, for example, on the surface of the heat insulating structure. As an example of the heat insulating structure, in the example of FIG. 7, the refractory brick Re1 that forms the surface of the heat insulating structure and the refractory brick Re2 that forms the installation space S in which the heat insulating material unit 300 is disposed using the refractory brick Re1 as the installation surface.

　耐火レンガＲｅ２は、耐火レンガＲｅ１から垂直方向に延びるように配置され、一対の耐火レンガＲｅ２間に、設置空間Ｓが形成される。設置空間ＳのＺ方向の幅は、断熱材ユニット３００のＺ方向の幅に対応しており、断熱材ユニット３００のＹ方向の長さは、設置空間ＳのＹ方向長さに対応している。 The refractory brick Re2 is disposed so as to extend in the vertical direction from the refractory brick Re1, and an installation space S is formed between the pair of refractory bricks Re2. The width of the installation space S in the Z direction corresponds to the width of the heat insulating material unit 300 in the Z direction, and the length of the heat insulating material unit 300 in the Y direction corresponds to the length of the installation space S in the Y direction. .
　そして、図７に示すように、固定部材２０１側を設置空間Ｓへの設置方向として、断熱材ユニット３００が設置空間Ｓ内に挿入され、断熱構造体の表面にライニングされる。したがって、設置空間Ｓ内に挿入された断熱材ユニット３００の底部側、すなわち、樹脂プレートの被折曲部１１０は、設置空間Ｓに対して露出している。なお、耐火レンガＲｅ１に固定部材２０１を固定するように設置空間Ｓに断熱材ユニット３００を配置することもできる。 Then, as shown in FIG. 7, the heat insulating material unit 300 is inserted into the installation space S with the fixing member 201 side as the installation direction in the installation space S, and is lined on the surface of the heat insulation structure. Therefore, the bottom side of the heat insulating material unit 300 inserted into the installation space S, that is, the bent portion 110 of the resin plate is exposed to the installation space S. In addition, the heat insulating material unit 300 can also be arrange | positioned in the installation space S so that the fixing member 201 may be fixed to the refractory brick Re1.
　図８は、図７に示した断熱構造体に断熱材ユニット３００を配設する際の作業工程を示す図である。まず、作業員は、断熱構造体の設置空間Ｓに断熱材ユニット３００を挿入する。このとき、断熱材ユニット３００は、Ｚ方向左右に配置されている樹脂プレートが、耐火レンガＲｅ２と断熱材ブロック２００との間に位置するように、設置空間Ｓ内に挿入される。 FIG. 8 is a diagram showing an operation process when the heat insulating material unit 300 is disposed in the heat insulating structure shown in FIG. First, the worker inserts the heat insulating material unit 300 into the installation space S of the heat insulating structure. At this time, the heat insulating material unit 300 is inserted into the installation space S so that the resin plates arranged on the left and right in the Z direction are located between the firebrick Re2 and the heat insulating material block 200.
　次に、作業員は、設置空間Ｓ内に挿入された断熱材ユニット３００の拘束バンドＫＢを切断して取り除く。拘束バンドＫＢを取り除くと、圧縮されていた断熱材ブロック２００は、上下左右方向それぞれに膨張する。断熱材ブロック２００がＺ方向左右に膨張することで、各樹脂プレートは、耐火レンガＲｅ２に対して押圧され、断熱材ブロック２００と耐火レンガＲｅ２との間に挟まれる。このように、被折曲部１１０を除く断熱材ブロック２００と耐火レンガＲｅ２との間に挟まれるプレート体１００の領域が、ガイド部材（ガイド面）として構成される。 Next, the worker cuts and removes the restraining band KB of the heat insulating material unit 300 inserted in the installation space S. When the restraining band KB is removed, the compressed heat insulating material block 200 expands in the vertical and horizontal directions. As the heat insulating material block 200 expands left and right in the Z direction, each resin plate is pressed against the refractory brick Re2, and is sandwiched between the heat insulating material block 200 and the refractory brick Re2. Thus, the area | region of the plate body 100 pinched | interposed between the heat insulating material block 200 except the bent part 110, and the refractory brick Re2 is comprised as a guide member (guide surface).
　一方、断熱材ブロック２００がＹ方向上下に膨張することで、断熱材ブロック２００の底部側に位置する各樹脂プレートの被折曲部１１０が、設置空間Ｓに対してＺ方向外側に押圧される。このため、Ｚ方向に略平行に延びるように配置されていた被折曲部１１０は、断熱材ブロック２００の底部から離れる方向に傾斜する。 On the other hand, when the heat insulating material block 200 expands vertically in the Y direction, the bent portion 110 of each resin plate positioned on the bottom side of the heat insulating material block 200 is pressed outward in the Z direction with respect to the installation space S. . For this reason, the bent portion 110 arranged so as to extend substantially parallel to the Z direction is inclined in a direction away from the bottom of the heat insulating material block 200.
　被折曲部１１０は、設置空間Ｓ内に配置されたガイド部材（樹脂プレート）を取り除く（引き抜く）ために作業員によって把持される（即ち、被折曲部１１０は把持可能な把持部として機能する）。二点鎖線で示すように、作業員は、被折曲部１１０を掴んで設置空間Ｓの外側に向かって引き抜くことができる。このとき、耐火レンガＲｅ２に当接する樹脂プレートの表面１０１は、摩擦係数が小さいため、容易に引き抜くことができる。 The bent portion 110 is gripped by an operator in order to remove (pull out) the guide member (resin plate) disposed in the installation space S (that is, the bent portion 110 functions as a grippable gripping portion. To do). As indicated by a two-dot chain line, the worker can grasp the bent portion 110 and pull it out of the installation space S. At this time, the surface 101 of the resin plate that comes into contact with the refractory brick Re2 can be easily pulled out because the coefficient of friction is small.
　例えば、摩擦係数が大きいガイド部材を使用すると、ガイド部材が設置空間Ｓ内で耐火レンガＲｅ２に押圧されているため、設置空間Ｓからガイド部材を引き抜こうとすると、折り曲げ部１２０に過度の引っ張り力が加わり、被折曲部１１０との連結部（例えば、高密度部１２１）が破断してしまうおそれがある。また、断熱材ブロック２００との間でも摩擦係数が大きくなり、設置空間Ｓからガイド部材を引く抜く際に、断熱材ブロック２００も設置空間Ｓ内から外側に飛び出てしまうおそれがあり、作業性が低下する。 For example, when a guide member having a large friction coefficient is used, the guide member is pressed against the refractory bricks Re2 in the installation space S. Therefore, when the guide member is pulled out of the installation space S, an excessive tensile force is applied to the bent portion 120. In addition, there is a possibility that the connecting portion (for example, the high density portion 121) with the bent portion 110 may be broken. In addition, the coefficient of friction increases with the heat insulating material block 200, and when the guide member is pulled out of the installation space S, the heat insulating material block 200 may also jump out of the installation space S, and workability is improved. descend.
　本実施形態の断熱材ユニット３００は、表面１０１及び表面１０２の摩擦係数が小さい樹脂プレートをガイド部材として使用しているため、折り曲げ部１２０に過度の引っ張り力が加わることを抑制しつつ、断熱材ブロック２００の設置作業性を向上させることができる。 Since the heat insulating material unit 300 of the present embodiment uses a resin plate having a small coefficient of friction between the surface 101 and the surface 102 as a guide member, the heat insulating material is suppressed while applying an excessive tensile force to the bent portion 120. The installation workability of the block 200 can be improved.
　なお、図７及び図８に示した断熱構造体を一例として、断熱材ユニット３００の設置方法を説明したが、例えば、耐火レンガＲｅ２で設置空間Ｓを区画せずに、断熱材ユニット３００同士を直接隣接させてライニングすることもできる。このような場合であっても、断熱材ブロック２００の設置作業性を向上させることができる。 In addition, although the installation method of the heat insulating material unit 300 was demonstrated taking the heat insulation structure shown in FIG.7 and FIG.8 as an example, for example, without partitioning the installation space S by the refractory bricks Re2, the heat insulating material units 300 may be connected to each other. It can also be lined directly adjacent. Even in such a case, the installation workability of the heat insulating material block 200 can be improved.
