Description

本発明は、低温液化ガスタンク等の低温タンクの底版と側壁との間のコーナ部にメンブレンを固定するための低温タンクのコーナ部用メンブレンアンカーに関するものである。   The present invention relates to a membrane anchor for a corner portion of a low temperature tank for fixing a membrane to a corner portion between a bottom plate and a side wall of a low temperature tank such as a low temperature liquefied gas tank.

低温タンクとしての低温液化ガスタンクは、一般に、図3(イ)(ロ)にその一例の概略を示す如く、底版1と円筒型(厳密には多角筒状)の側壁2により円柱状の貯蔵空間3を形成して、該貯蔵空間3に低温液化ガス(図示せず)を貯蔵するようにしてある。又、上記底版1と側壁2は、液圧に耐えるようにコンクリート躯体としてあり、且つ上記底版1と側壁2の内面に、その内面全体を覆うように保冷材4を配置すると共に、該保冷材4の内側に、液密性を確保するための薄い金属製のメンブレン5a,5bを取り付けた構成としてある。   A low-temperature liquefied gas tank as a low-temperature tank is generally a cylindrical storage space that includes a bottom plate 1 and a cylindrical (strictly polygonal cylindrical) side wall 2 as shown schematically in FIG. 3 is formed, and a low-temperature liquefied gas (not shown) is stored in the storage space 3. The bottom plate 1 and the side wall 2 are made of concrete so as to withstand the hydraulic pressure, and the cold insulating material 4 is disposed on the inner surfaces of the bottom plate 1 and the side wall 2 so as to cover the entire inner surface, and the cold insulating material. 4, thin metal membranes 5 a and 5 b for securing liquid tightness are attached.

更に、たとえば、LNGの液化温度が約−162℃であるように、上記低温液化ガスタンクに貯蔵する低温液化ガスは、極低温となっているため、上記低温液化ガスタンクは、大きな熱収縮を許容できる構成とすることが求められる。そのために、上記メンブレン5a,5bは、ステンレス板によって上記貯蔵空間3の底部及び側壁部を多数に分割した形状に形成してあると共に、個々のメンブレン5a,5bにおける所要個所には、半径方向と周方向に延びるか、又は、互いに直交する2方向へ延びるコルゲーション(襞)6をそれぞれ設けてなる構成として、該コルゲーション6が変形することで、大きな熱収縮を吸収できるようにしてある。   Further, for example, the low-temperature liquefied gas stored in the low-temperature liquefied gas tank is extremely low so that the liquefaction temperature of LNG is about −162 ° C. Therefore, the low-temperature liquefied gas tank can tolerate large heat shrinkage. It is required to have a configuration. For this purpose, the membranes 5a and 5b are formed in a shape in which the bottom and side walls of the storage space 3 are divided into a large number by a stainless steel plate, and the required positions in the individual membranes 5a and 5b are arranged in the radial direction. The corrugation 6 extends in the circumferential direction or extends in two directions orthogonal to each other, and the corrugation 6 is deformed to absorb a large thermal contraction.

なお、上記メンブレン5a,5bは、上記躯体である底版1又は側壁2の対応する個所に、メンブレン5a,5bの熱をコンクリート躯体に伝熱させない断熱構造を有するメンブレンアンカー7を介して連結することで、上記したように底版1及び側壁2の内側に配置してある各メンブレン5a,5bに熱収縮が生じても、全体形状が変形しないようにしてある。   The membranes 5a and 5b are connected to corresponding portions of the bottom plate 1 or the side wall 2 which is the above-mentioned casing via a membrane anchor 7 having a heat insulating structure that does not transfer the heat of the membranes 5a and 5b to the concrete casing. Thus, as described above, even when the membranes 5a and 5b arranged inside the bottom plate 1 and the side wall 2 are thermally contracted, the overall shape is not deformed.

ところで、上記コンクリート躯体の底版1及び側壁2を有する形式の低温液化ガスタンクでは、一般に、図3(ロ)に示す如く、上記底版1と側壁2との間のコーナ部に、躯体の剛性を高めるためのハンチ構造部8、たとえば、底版1及び側壁2の内面より45度ずつ傾斜した傾斜面となるハンチ構造部8を設けるようにしてある。   By the way, in the low temperature liquefied gas tank of the type having the bottom plate 1 and the side wall 2 of the concrete case, generally, the rigidity of the case is increased at the corner portion between the bottom plate 1 and the side wall 2 as shown in FIG. For example, a haunch structure portion 8 having an inclined surface inclined by 45 degrees from the inner surfaces of the bottom plate 1 and the side wall 2 is provided.

したがって、上記ハンチ構造部8の内面にも、上記底版1及び側壁2の内面と同様にして、保冷材4とメンブレン5を取り付ける必要が生じる。この場合、上記ハンチ構造部8の内面に沿って配置するコーナ部のメンブレン5は、上記底版1の内面に配する底部のメンブレン5aと、側壁2の内面に配する側部のメンブレン5bのいずれに対しても45度ずつ傾斜した配置となる。   Therefore, it is necessary to attach the cold insulating material 4 and the membrane 5 to the inner surface of the haunch structure portion 8 in the same manner as the inner surfaces of the bottom plate 1 and the side wall 2. In this case, the corner portion membrane 5 arranged along the inner surface of the haunch structure portion 8 may be either a bottom membrane 5 a disposed on the inner surface of the bottom plate 1 or a side membrane 5 b disposed on the inner surface of the side wall 2. Is inclined by 45 degrees.

そのために、上記コーナ部のメンブレン5は、その下端部を、底版1の外周部におけるハンチ構造部8との境界部付近に配設したコーナ部用メンブレンアンカー9に取り付けて支持させるようにしてあり、且つ該コーナ部用メンブレンアンカー9に、底部のメンブレン5aの外周端部を取り付けることで、上記コーナ部のメンブレン5と底部のメンブレン5aの端部同士を、上記コーナ部用メンブレンアンカー9を介して位置固定してある。又、上記コーナ部のメンブレン5の上端部は、側壁2の下端部におけるハンチ構造部8との境界部付近に配設したコーナ部用メンブレンアンカー9に取り付けて支持させるようにしてあり、且つ該コーナ部用メンブレンアンカー9に、側部のメンブレン5bの下端部を取り付けることで、上記コーナ部のメンブレン5と側部のメンブレン5bの端部同士を、上記コーナ部用メンブレンアンカー9を介して位置固定できるようにしてある(たとえば、特許文献1参照)。これにより、各メンブレン5,5a,5bに熱収縮変形が生じる際にも、上記コーナ部のメンブレン5に浮き上がりが生じる虞を未然に防止できるようにしてある。   For this purpose, the membrane 5 of the corner portion is attached to and supported by a corner portion membrane anchor 9 disposed in the vicinity of the boundary between the outer peripheral portion of the bottom plate 1 and the haunch structure portion 8. Further, by attaching the outer peripheral end portion of the bottom membrane 5a to the corner portion membrane anchor 9, the end portions of the corner portion membrane 5 and the bottom portion membrane 5a are connected to each other via the corner portion membrane anchor 9. The position is fixed. Further, the upper end portion of the membrane 5 in the corner portion is attached to and supported by a corner portion membrane anchor 9 disposed in the vicinity of the boundary portion between the lower end portion of the side wall 2 and the haunch structure portion 8, and By attaching the lower end of the side membrane 5b to the corner membrane anchor 9, the ends of the corner membrane 5 and the side membrane 5b are positioned via the corner membrane anchor 9 above. It can be fixed (see, for example, Patent Document 1). Thereby, even when heat shrink deformation occurs in each of the membranes 5, 5 a, 5 b, it is possible to prevent the possibility that the membrane 5 at the corner portion is lifted.

上記コーナ部用メンブレンアンカー9としては、従来、図4(イ)(ロ)に示す如き構成のものが用いられてきている。   As the membrane anchor 9 for the corner portion, conventionally, one having a structure as shown in FIGS. 4 (A) and 4 (B) has been used.

すなわち、図4(イ)(ロ)に示したコーナ部用メンブレンアンカー9は、硬質発泡ポリウレタンフォーム(PUF)により矩形断面形状を有するブロック状に成形した基部保冷部材10の上面に、荷重を均一に分散させるための合板の如き板状部材11が全面に亘り一体に取り付けてある。更に、上記板状部材11の上側には、所要の高さ寸法を有し、上面の幅方向の中央部から一端部(図上左端部)までを上記板状部材11と平行な水平面部12aとし、且つ幅方向の中央部から他端部(図上右端部)までを他端側が高くなるように上記板状部材11に対して斜め45度の傾斜角度で傾斜させた傾斜面部12bとしてなる下端の開放された中空状のメンブレン支持金物12を、その内部空間に上記基部保冷部材10と同様の材質による上部保冷部材13を充填した状態で載置する。更に、上記基部保冷部材10及び板状部材11の幅方向両端部に上下方向に穿設してあるボルト孔14と、上記メンブレン支持金物12の幅方向両端面にそれぞれ取り付けたアングル材15に設けたボルト孔16に、低温液化ガスタンクのコンクリート躯体の所要個所に設置したアンカーボルト17をそれぞれ挿通させると共に、該各アンカーボルト17の先端部にナット18を螺着させて締めることで、上記基部保冷部材10及び板状部材11に、上記メンブレン支持金物12を連結してコーナ部用メンブレンアンカー9を形成すると同時に、該コーナ部用メンブレンアンカー9のコンクリート躯体への据付けを行うことができるようにしてある。   That is, the corner portion membrane anchor 9 shown in FIGS. 4 (a) and 4 (b) has a uniform load applied to the upper surface of the base cold insulation member 10 formed into a block shape having a rectangular cross-sectional shape by a hard foamed polyurethane foam (PUF). A plate-like member 11 such as a plywood for dispersion is integrally attached over the entire surface. Further, on the upper side of the plate-like member 11, a horizontal surface portion 12 a having a required height dimension and parallel to the plate-like member 11 from the center portion in the width direction of the upper surface to one end portion (left end portion in the drawing). In addition, the inclined surface portion 12b is inclined from the central member in the width direction to the other end portion (right end portion in the figure) at an inclination angle of 45 degrees with respect to the plate member 11 so that the other end side becomes higher. The hollow membrane support metal 12 with the lower end opened is placed in a state in which the inner space is filled with the upper cooling member 13 made of the same material as the base cooling member 10. Furthermore, the base cold-retaining member 10 and the plate-like member 11 are provided in bolt holes 14 drilled in the vertical direction at both ends in the width direction, and angle members 15 attached to the both ends in the width direction of the membrane support metal 12 respectively. Each of the bolt holes 16 is inserted with an anchor bolt 17 installed at a required portion of the concrete frame of the low-temperature liquefied gas tank, and a nut 18 is screwed to the tip of each anchor bolt 17 to be tightened. The membrane support metal 12 is connected to the member 10 and the plate-like member 11 to form the corner portion membrane anchor 9, and at the same time, the corner portion membrane anchor 9 can be installed on the concrete frame. is there.

したがって、上記構成としてあるコーナ部用メンブレンアンカー9を用いてコーナ部のメンブレン5の下端部を支持させる場合には、上記アンカーボルト17として、図4(イ)に示す如く、低温液化ガスタンクの底版1の外周部における上記ハンチ構造部8との境界部付近に予め垂直に設置したアンカーボルト17を用いることにより、上記コーナ部用メンブレンアンカー9を、メンブレン支持金物12の傾斜面部12bがハンチ構造部8側に位置するようにして底版1の外周部に据付ける。この状態にて、上記メンブレン支持金物12の傾斜面部12bの上側に、ハンチ構造部8の内面に沿って配設するコーナ部のメンブレン5の下端部を所要寸法重ねるよう配置して、溶接等により固定するようにしてある。又、上記メンブレン支持金物12の水平面部12aの上側には、底部のメンブレン5aの外周端部を所要寸法重ねるよう配置して、溶接等により固定するようにしてある。   Therefore, when supporting the lower end portion of the membrane 5 of the corner portion by using the membrane anchor 9 for the corner portion having the above-described configuration, the anchor bolt 17 is used as the bottom plate of the low temperature liquefied gas tank as shown in FIG. By using anchor bolts 17 installed in the vicinity of the boundary with the haunch structure portion 8 in the outer peripheral portion of 1 in advance, the inclined portion 12b of the membrane support metal 12 is used as the hunch structure portion. It is installed on the outer periphery of the bottom plate 1 so as to be positioned on the 8 side. In this state, the lower end portion of the membrane 5 of the corner portion disposed along the inner surface of the haunch structure portion 8 is arranged on the upper side of the inclined surface portion 12b of the membrane support metal piece 12 so as to overlap the required dimensions, and by welding or the like. It is supposed to be fixed. Further, on the upper side of the horizontal surface portion 12a of the membrane supporting metal 12, the outer peripheral end portion of the membrane 5a at the bottom portion is disposed so as to overlap with a required dimension, and is fixed by welding or the like.

更に、図示してないが、上記コーナ部用メンブレンアンカー9を用いてコーナ部のメンブレン5の上端部を支持させる場合は、上記アンカーボルト17として、予め低温液化ガスタンクの側壁2の下端部における上記ハンチ構造部8との境界部付近に水平に設置したアンカーボルト17を用いることにより、上記コーナ部用メンブレンアンカー9を、メンブレン支持金物12の傾斜面部12bがハンチ構造部8側となる下方に位置するように横向きの姿勢とした状態で上記側壁2の下端部に据付け、この状態にて、上記コーナ部用メンブレンアンカー9における上記メンブレン支持金物12の傾斜面部12bに、ハンチ構造部8の内面に沿って配設するコーナ部のメンブレン5の上端部を所要寸法重ねて配置して、溶接等により固定し、又、横向きとしてある上記メンブレン支持金物12の水平面部12aに、側部のメンブレン5bの下端部を所要寸法重ねて配置して、溶接等により固定するようにしてある。   Further, although not shown, when the upper end portion of the membrane 5 of the corner portion is supported using the membrane anchor 9 for the corner portion, the anchor bolt 17 is used as the anchor bolt 17 in advance at the lower end portion of the side wall 2 of the low temperature liquefied gas tank. By using anchor bolts 17 installed horizontally in the vicinity of the boundary with the haunch structure portion 8, the corner portion membrane anchor 9 is positioned below the inclined surface portion 12 b of the membrane support hardware 12 on the haunch structure portion 8 side. In this state, it is installed at the lower end of the side wall 2, and in this state, on the inclined surface portion 12 b of the membrane support metal 12 in the corner portion membrane anchor 9, on the inner surface of the haunch structure portion 8. The upper end portion of the membrane 5 of the corner portion disposed along the upper end portion is disposed so as to overlap with the required dimension, and is fixed by welding or the like. The horizontal portion 12a of the membrane support fittings 12 with the orientation and disposed to overlap the required dimensions lower end of the side of the membrane 5b, are to be fixed by welding or the like.

ところが、図4(イ)(ロ)に示した従来のコーナ部用メンブレンアンカー9は、コンクリート躯体への取付側となる基部保冷部材10が矩形断面形状として、平らな底面を備えた形状としてあって、水平又は垂直の平面に据付けることが前提とされていた。そのために、上記コーナ部用メンブレンアンカー9を低温液化ガスタンクの底版1の外周部における上記ハンチ構造部8との境界部付近に据付ける場合は、図3(ロ)及び図4(イ)に示す如く、該ハンチ構造部8における上記底版1側の端縁部となる内周側端部を所要寸法切り欠くように加工して、該切欠加工部分8aに上記コーナ部用メンブレンアンカー9を設置するための水平な底版1を露出させるようにする必要があり、又、上記コーナ部用メンブレンアンカー9を低温液化ガスタンクの側壁2の下端部における上記ハンチ構造部8との境界部付近に据付ける場合は、図3(ロ)に示す如く、該ハンチ構造部8における上記側壁2の端縁部となる上端部を所要寸法水平に切り欠くように加工して、該切欠加工部分8bに上記コーナ部用メンブレンアンカー9を設置するための垂直な側壁を露出させるようにする必要があることから、上記ハンチ構造部8を特殊な構造にする必要が生じ、そのための設計及び施工の手間が嵩んでいるというのが実状である。   However, the conventional membrane anchor 9 for the corner portion shown in FIGS. 4 (a) and 4 (b) has a shape in which the base cold insulation member 10 on the side to be attached to the concrete frame has a rectangular cross-sectional shape and a flat bottom surface. Therefore, it was assumed to be installed on a horizontal or vertical plane. Therefore, when installing the corner portion membrane anchor 9 near the boundary with the haunch structure portion 8 in the outer peripheral portion of the bottom slab 1 of the low temperature liquefied gas tank, it is shown in FIGS. 3 (b) and 4 (a). As described above, the inner peripheral side end portion which is the edge portion on the bottom plate 1 side in the haunch structure portion 8 is processed so as to be cut out with a required dimension, and the corner portion membrane anchor 9 is installed in the notched portion 8a. It is necessary to expose the horizontal bottom plate 1 for the purpose, and when the corner membrane anchor 9 is installed near the boundary with the haunch structure 8 at the lower end of the side wall 2 of the low temperature liquefied gas tank As shown in FIG. 3 (b), the upper end portion which is the edge portion of the side wall 2 in the haunch structure portion 8 is machined so as to be cut out in the required dimension horizontally, and the corner portion is formed in the notched portion 8b. Since it is necessary to expose the vertical side wall for installing the membrane anchor 9, it is necessary to make the haunch structure portion 8 a special structure, and the design and construction work therefor is increased. This is the actual situation.

そこで、本発明は、低温タンクの底版と側壁との間のコーナ部に設けるハンチ構造部を特殊な構造にすることなく、ハンチ構造部の内側に配するメンブレンの上端部と下端部の固定を行うことができるようにした低温タンクのコーナ部用メンブレンアンカーを提供しようとするものである。   Therefore, the present invention fixes the upper and lower ends of the membrane disposed inside the haunch structure without making the haunch structure provided in the corner between the bottom plate and the side wall of the cryogenic tank special. An object of the present invention is to provide a membrane anchor for a corner portion of a cryogenic tank that can be performed.

本発明は、上記課題を解決するために、請求項1に対応して、底版と側壁との間のコーナ部にハンチ構造部を有する低温タンクにおける上記底版とハンチ構造部のなす角、又は、上記側壁とハンチ構造部のなす角と対応する角度で屈曲する断面V字形状の基部保冷部材の上側に、荷重を均一に分散させるための板状部材を全面に亘り取り付け、更に、上記板状部材の上側に、所要の高さ寸法を有し且つ上面を幅方向の中央部で上記基部保冷部材と同様の角度で屈曲させてなる略M字形状のメンブレン支持金物を、内部に上部保冷部材を充填した状態で取り付けてなり、上記メンブレン支持金物の上面にコーナ部のメンブレンの端部と底部側又は側部側のメンブレンの端部を固定できるようにした構成とする。   In order to solve the above-mentioned problem, the present invention corresponds to claim 1, and an angle formed between the bottom plate and the haunch structure portion in a low temperature tank having a haunch structure portion at a corner portion between the bottom plate and the side wall, or A plate-like member for evenly distributing the load is attached to the entire upper surface of the base cold insulation member having a V-shaped cross section that is bent at an angle corresponding to the angle formed by the side wall and the haunch structure portion. On the upper side of the member, a substantially M-shaped membrane supporting hardware having a required height dimension and having the upper surface bent at the same angle as that of the base cooling member at the center in the width direction is provided inside the upper cooling member. The end of the corner of the membrane and the end of the bottom or side membrane can be fixed to the upper surface of the membrane support metal.

本発明の低温タンクのコーナ部用メンブレンアンカーによれば、以下のような優れた効果を発揮する。
(1)底版と側壁との間のコーナ部にハンチ構造部を有する低温タンクにおける上記底版とハンチ構造部のなす角、又は、上記側壁とハンチ構造部のなす角と対応する角度で屈曲する断面V字形状の基部保冷部材の上側に、荷重を均一に分散させるための板状部材を全面に亘り取り付け、更に、上記板状部材の上側に、所要の高さ寸法を有し且つ上面を幅方向の中央部で上記基部保冷部材と同様の角度で屈曲させてなる略M字形状のメンブレン支持金物を、内部に上部保冷部材を充填した状態で取り付けてなり、上記メンブレン支持金物の上面にコーナ部のメンブレンの端部と底部側又は側部側のメンブレンの端部を固定できるようにした構成としてあるので、低温液化ガスタンクの底版とハンチ構造部との間に形成されているV字形状の境界部に、上記基部保冷部材の屈曲部を嵌合させるように配置した状態で上記底版及びハンチ構造部への据付けを行うと、上記メンブレン支持金物の上面における幅方向中央部を挟んで一方の領域をハンチ構造部と平行に、又、他方の領域を底版と平行に配置させることができる。よって、上記メンブレン支持金物の上面におけるハンチ構造部と平行な領域には、上記ハンチ構造部の内側に配置するコーナ部メンブレンの下端部を、又、該メンブレン支持金物の上面における底版と平行な領域には、底部メンブレンの外周端部をそれぞれ取り付けて固定することができる。
(2)又、低温液化ガスタンクの側壁とハンチ構造部との間に形成されているV字形状の境界部に、上記基部保冷部材の屈曲部を嵌合させるように配置した状態で上記側壁及びハンチ構造部への据付けを行うと、この据付けによって横向き姿勢となる上記メンブレン支持金物の上面における幅方向中央部を挟んで一方の領域をハンチ構造部と平行に、又、他方の領域を側壁と平行に配置させることができる。よって、上記メンブレン支持金物の上面におけるハンチ構造部と平行な領域には、上記ハンチ構造部の内側に配置するコーナ部メンブレンの上端部を、又、該メンブレン支持金物の上面における側壁と平行な面部には、側部メンブレンの下端部を取り付けて固定することができる。
(3)したがって、低温タンクにおける底版とハンチ構造部との境界部、及び、側壁とハンチ構造部との境界部に据付けを行う際に、従来のコーナ部用メンブレンアンカーの設置時に要していたような上記ハンチ構造部を特殊な構造にするための加工を不要にできて、設計及び施工の手間の大幅な削減化を図ることができる。
According to the membrane anchor for the corner portion of the low temperature tank of the present invention, the following excellent effects are exhibited.
(1) A cross section that bends at an angle between the bottom plate and the haunch structure portion in a low-temperature tank having a haunch structure portion at a corner portion between the bottom plate and the side wall, or at an angle corresponding to the angle formed between the side wall and the haunch structure portion. A plate-like member for evenly distributing the load is attached to the entire upper side of the V-shaped base cold insulation member, and further, the upper side of the plate-like member has a required height dimension and the upper surface is wide. A substantially M-shaped membrane support metal bent at the same angle as the base cold insulation member at the center of the direction is attached in a state where the upper cold insulation member is filled inside, and a corner is formed on the upper surface of the membrane support metal. V-shaped formed between the bottom plate of the cryogenic liquefied gas tank and the haunch structure part because the end of the membrane and the end of the membrane on the bottom side or side part can be fixed. Border When the base plate and the haunch structure part are installed in a state where the bent part of the base cold insulation member is fitted to the part, one region sandwiching the central part in the width direction on the upper surface of the membrane support hardware Can be arranged in parallel with the haunch structure and the other region can be arranged in parallel with the bottom plate. Therefore, in the region parallel to the haunch structure portion on the upper surface of the membrane support metal fitting, the lower end portion of the corner membrane disposed inside the haunch structure portion, and the region parallel to the bottom plate on the upper surface of the membrane support metal fitting The outer peripheral end of the bottom membrane can be attached and fixed respectively.
(2) In addition, in the state where the bent portion of the base cooling member is fitted to the V-shaped boundary portion formed between the side wall of the cryogenic liquefied gas tank and the haunch structure portion, When installed on the haunch structure part, one region is parallel to the haunch structure part and the other region is a side wall across the central portion in the width direction on the upper surface of the membrane supporting metal that is placed in a lateral orientation by this installation. They can be arranged in parallel. Therefore, in the region parallel to the haunch structure part on the upper surface of the membrane support metal part, the upper end part of the corner membrane disposed inside the haunch structure part is also provided, and the surface part parallel to the side wall on the upper surface of the membrane support metal part Can be fixed by attaching the lower end of the side membrane.
(3) Therefore, when installing at the boundary portion between the bottom plate and the haunch structure portion and the boundary portion between the side wall and the haunch structure portion in the low temperature tank, it was necessary when installing the conventional membrane anchor for the corner portion. Such a process for making the haunch structure part into a special structure can be made unnecessary, and the labor for designing and construction can be greatly reduced.

以下、本発明を実施するための最良の形態を図面を参照して説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

図1(イ)(ロ)及び図2は本発明の低温タンクのコーナ部用メンブレンアンカーの実施の一形態を示すもので、硬質発泡ポリウレタンフォーム(PUF)により、幅方向中央部にて、低温液化ガスタンクにおける底版1とハンチ構造部8とがなす角(平面角)や、側壁2とハンチ構造部8がなす角(平面角)と対応するように、たとえば、低温液化ガスタンクの底版1と側壁2との間のコーナ部に底版1及び側壁2の内面よりそれぞれ45度ずつ傾斜した傾斜面となるようにハンチ構造部8が設けてある場合は、135度の角度で屈曲する断面V字形状のブロック状の基部保冷部材20を形成する。該基部保冷部材20の上面には、荷重を均一に分散させるための合板の如き板状部材21を全面に亘り一体に取り付ける。   1 (a), (b) and FIG. 2 show an embodiment of a membrane anchor for a corner portion of a low temperature tank according to the present invention, and the temperature is lowered at the center in the width direction by a rigid foamed polyurethane foam (PUF). For example, the bottom plate 1 and the side wall of the low temperature liquefied gas tank may correspond to the angle (plane angle) formed by the bottom plate 1 and the haunch structure portion 8 in the liquefied gas tank and the angle (plane angle) formed by the side wall 2 and the haunch structure portion 8. When the haunch structure portion 8 is provided at the corner portion between the bottom plate 1 and the inner surface of the side wall 2 so as to be inclined by 45 degrees, the V-shaped cross section is bent at an angle of 135 degrees.
