Description

本発明は、コンクリート製筒状壁の壁内周面を覆う複数の金属製ライナープレートを、そのプレート側辺部を前記筒状壁に埋設固定してある複数の金属製アンカー部材のプレート固定部に溶接して固定するために、前記アンカー部材の複数を前記筒状壁のコンクリート打設用型枠の内側に仮固定しておき、前記型枠の内側にコンクリートを打設した後、前記型枠を撤去して、前記複数のアンカー部材を、前記プレート固定部を前記壁内周面側に臨ませて、前記筒状壁に埋設固定するアンカー部材固定方法に使用するアンカー部材連結体に関する。   The present invention provides a plate fixing portion of a plurality of metal anchor members in which a plurality of metal liner plates covering the wall inner peripheral surface of a concrete cylindrical wall are fixedly embedded in the cylindrical wall. A plurality of anchor members are temporarily fixed inside a concrete casting mold of the cylindrical wall, and concrete is placed inside the mold, and then the mold is fixed. The present invention relates to an anchor member coupling body used for an anchor member fixing method in which a frame is removed and the plurality of anchor members are embedded and fixed in the cylindrical wall with the plate fixing portion facing the wall inner peripheral surface.

例えば、ドーム屋根の上面側を構成する上部屋根材と筒状外周壁と外底板とを一体に備えた金属製外槽の内側に、ドーム屋根の下面側を構成する下部屋根材と筒状内周壁と内底板とを一体に備えた金属製内槽を設けるとともに、外槽と内槽との間に断熱層を設けて貯留槽を構成し、内槽の内側を低温液化ガスの貯留部に形成してある低温液化ガス貯留設備においては、外槽の外周側を囲む防液堤としてのコンクリート製筒状壁を設けて、この筒状壁で外槽の強度を補強できるように、外槽の筒状外周壁を、筒状壁の内周側に壁内周面を覆うように固定してある複数の金属製ライナープレートで構成してある。
上記アンカー部材固定方法は、これら複数のライナープレートを筒状壁の壁内周面側に固定するための金属製アンカー部材を筒状壁に埋設固定する方法であり、従来、アンカー部材の筒状壁に対する固定位置を位置決めしておけば、プレート固定部の壁内周面に沿う回転姿勢にかかわらず、プレート側辺部のプレート固定部に対する溶接長さを確保できるように、プレート固定部の形状が筒状壁に埋設するアンカー軸と同芯状の略円形に形成してあるアンカー部材を使用している（例えば、特許文献１参照）。 For example, inside the metal outer tub that is integrally provided with the upper roof material that forms the upper surface side of the dome roof, the cylindrical outer peripheral wall, and the outer bottom plate, the lower roof material that forms the lower surface side of the dome roof and the cylindrical inner In addition to providing a metal inner tank with a peripheral wall and an inner bottom plate integrally, a storage tank is formed by providing a heat insulating layer between the outer tank and the inner tank, and the inside of the inner tank serves as a cryogenic liquefied gas storage section. In the low-temperature liquefied gas storage facility that is formed, the outer tank is provided with a concrete cylindrical wall as a liquid barrier surrounding the outer peripheral side of the outer tank so that the strength of the outer tank can be reinforced by this cylindrical wall. This cylindrical outer peripheral wall is constituted by a plurality of metal liner plates fixed to the inner peripheral side of the cylindrical wall so as to cover the inner peripheral surface of the wall.
The anchor member fixing method is a method of embedding and fixing a metal anchor member for fixing the plurality of liner plates to the inner peripheral surface side of the cylindrical wall in the cylindrical wall. If the fixing position with respect to the wall is positioned, the shape of the plate fixing part can be secured so that the welded length of the plate side part to the plate fixing part can be secured regardless of the rotational posture along the wall inner peripheral surface of the plate fixing part. Uses an anchor member formed in a substantially circular shape concentric with an anchor shaft embedded in a cylindrical wall (see, for example, Patent Document 1).

上記従来技術によれば、プレート固定部がプレート側辺部に沿って長い形状のアンカー部材を使用する場合に必要となる手間、つまり、プレート側辺部の溶接長さを確保できるように、プレート固定部の壁内周面に沿う回転姿勢をその長手方向がプレート側辺部に沿うように調整する手間を省ける利点があるものの、プレート固定部の形状を略円形に形成してあるために、プレート固定部の形状がプレート側辺部に沿って長い形状のアンカー部材に比べて材料の無駄が多くなる欠点がある。
本発明は上記実情に鑑みてなされたものであって、アンカー部材を型枠に仮固定する手間を特に増やすことなく、アンカー部材の材料の無駄を減らせるようにすることを目的とする。 According to the above-described conventional technology, the plate fixing portion is required to use the long-shaped anchor member along the plate side portion, so that the plate length can be secured so that the weld length of the plate side portion can be secured. Although there is an advantage of omitting the trouble of adjusting the rotation posture along the inner peripheral surface of the fixing portion so that the longitudinal direction thereof is along the side portion of the plate, the shape of the plate fixing portion is formed in a substantially circular shape, There is a disadvantage that the waste of material is increased as compared with an anchor member having a plate fixing portion that is long along the side of the plate.
The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce waste of the material of the anchor member without particularly increasing the labor for temporarily fixing the anchor member to the mold.

〔作用及び効果〕
プレート固定部の形状を略円形に形成してあるアンカー部材に比べて材料の無駄が少ない形状のプレート固定部、つまり、プレート側辺部に沿って長い形状のプレート固定部を備えたアンカー部材を使用して、そのアンカー部材の複数を、それらのプレート固定部の姿勢をプレート側辺部に沿う姿勢に保持可能に、予め、互いに連結しておき、そのアンカー部材の複数を互いに連結するアンカー部材連結体を、それらのプレート固定部の姿勢がプレート側辺部に沿うように、型枠に仮固定しておくので、アンカー部材毎に、そのプレート固定部の壁内周面に沿う回転姿勢を長手方向がプレート側辺部に沿うように調整する手間を省きながら、プレート側辺部の溶接長さを確保できる姿勢で、複数のアンカー部材を型枠に仮固定しておくことができるようになり、アンカー部材を型枠に仮固定する手間を特に増やすことなく、アンカー部材の材料の無駄を減らせる。 [Action and effect]
Compared to an anchor member in which the shape of the plate fixing portion is formed in a substantially circular shape, a plate fixing portion having a shape with less waste of material, that is, an anchor member provided with a plate fixing portion having a long shape along the side portion of the plate. The anchor members that are connected to each other in advance so that a plurality of the anchor members can be held in a posture along the side portions of the plates, and the plurality of the anchor members are connected to each other. Since the connection body is temporarily fixed to the mold so that the posture of the plate fixing portion is along the side portion of the plate, the rotation posture along the inner peripheral surface of the plate fixing portion is set for each anchor member. It is possible to temporarily fix a plurality of anchor members to the formwork in a posture that can secure the welding length of the plate side portion while omitting the adjustment of the longitudinal direction along the plate side portion. Kill As will, without increasing in particular the need to temporarily fix the anchor member in a mold, Heraseru waste anchor member material.

また、アンカー部材の複数を可撓性を備えた索状部材で連結してあるので、索状部材を屈曲させて、アンカー部材連結体をコンパクトに折り畳んだ姿勢に保持することができ、アンカー部材連結体の保管や運搬などにおける取り扱いが容易になる。   In addition, since a plurality of anchor members are connected by a flexible cord-like member, the anchor-like member can be bent and held in a compactly folded posture. Handling in storage and transportation of the linked body becomes easy.
