折連支撐件10係鋼板製,形成連結於後述之起重裝置的被吊部。如第4、5圖所示,折連支撐件10係由:側面視時形成略三角形之一對的支撐板10a、10a;挾持於支撐板10a、10a間之平面視時為略正方形的被吊板10b;及挾持於支撐板10a、10a間,且連結於被吊板10b的上面以補強支撐板10a、10a與被吊板10b之間之補強板10c所形成。 The folding support 10 is made of a steel plate and forms a suspended portion that is coupled to a lifting device to be described later. As shown in FIGS. 4 and 5, the folding support 10 is composed of a pair of support plates 10a and 10a which are formed in a side view by a slight triangle when viewed from the side; the plane between the support plates 10a and 10a is slightly square. The hanging plate 10b is sandwiched between the support plates 10a and 10a, and is coupled to the upper surface of the suspended plate 10b to form a reinforcing plate 10c between the reinforcing support plates 10a and 10a and the suspended plate 10b.

如第4圖所示,支撐板10a、10a的一邊部係對應折連板9的彎曲形狀而彎曲,藉由熔接等安裝固定於折連板9的彎曲面。被吊板10b與補強板10c係藉由熔接等而互相連結的狀態下,如第5圖所示,藉由熔接、螺 鎖等安裝固定於支撐板10a、10a間。被吊板10b的外側端(側壁3側的一端)與支撐板10a、10a的外側端一致之狀態下,被吊板10b係被固定於支撐板10a、10a間。被吊板10b中,於折連板9的相反側,亦即朝向外槽的側壁3側,形成開口之缺口10d。缺口10d係成為連結於後述之起重裝置的被吊點。形成有缺口10d之被吊板10b係成為本發明中之被吊部。 As shown in Fig. 4, the one side portions of the support plates 10a and 10a are bent in accordance with the curved shape of the folding plate 9, and are fixed to the curved surface of the folding plate 9 by welding or the like. In a state in which the sling plate 10b and the reinforcing plate 10c are connected to each other by welding or the like, as shown in Fig. 5, by welding and snail The lock or the like is mounted and fixed between the support plates 10a and 10a. The outer end (the one end on the side of the side wall 3) of the suspended plate 10b is in a state of being aligned with the outer ends of the support plates 10a and 10a, and is fixed between the support plates 10a and 10a by the hanging plate 10b. In the suspended panel 10b, on the opposite side of the folding plate 9, that is, toward the side wall 3 side of the outer groove, an opening notch 10d is formed. The notch 10d is a suspended point that is connected to a lifting device to be described later. The suspended panel 10b having the notch 10d is a hanging portion in the present invention.

間隔維持件11係如第4、5圖所示,從折連板9的外周面向外側突出而設置。如第6圖所示,間隔維持件11係沿著折連板9的周方向,配設於等間隔地設置之折連支撐件10的各個之間,亦即成為被吊部之被吊板10b、10b之間。間隙維持件11係配設於相鄰之折連支撐件10、10間之略中央部,藉此,間隔維持件11亦沿著折連板9的周方向等間隔地設置。依此,間隔維持件11與折連支撐件10係沿著折連板9的周方向,互相等間隔地交互配置。 The spacers 11 are provided so as to protrude outward from the outer circumferential surface of the folding plate 9 as shown in Figs. 4 and 5 . As shown in Fig. 6, the spacers 11 are disposed along the circumferential direction of the folding plate 9 between the folded support members 10 which are disposed at equal intervals, that is, the suspended portions of the hanging portions. Between 10b and 10b. The gap maintaining member 11 is disposed at a substantially central portion between the adjacent folding supports 10 and 10, whereby the spacing maintaining members 11 are also provided at equal intervals along the circumferential direction of the folding plate 9. Accordingly, the spacers 11 and the folding support 10 are alternately arranged at equal intervals along the circumferential direction of the folding plate 9.

間隔維持件11係如第4、5圖所示,由例如與支撐板10a同樣地安裝於折連板9之一對鋼板(未圖示);挾持於該些鋼板間之H鋼11a;及貼設於H鋼11a的外端面之鋼板11b所形成。本實施型態中,如第4、5圖中實線及虛線所示,間隔維持件11係以折連板9的中心至間隔維持件11的外側端的距離,與折連板9的中心至形成被吊部之被吊板10b的外側端的距離成為相同長度之方式而配置。 The spacers 11 are attached to a pair of steel plates (not shown) of the folding plate 9 in the same manner as the support plates 10a, for example, as shown in Figs. 4 and 5; and the H steel 11a held between the steel plates; It is formed by the steel plate 11b attached to the outer end surface of the H steel 11a. In the present embodiment, as shown by the solid line and the broken line in FIGS. 4 and 5, the spacing maintaining member 11 is the distance from the center of the folding plate 9 to the outer end of the spacing maintaining member 11, and the center of the folding plate 9 is The distance between the outer ends of the suspended panels 10b of the suspended portion is set to be the same length.

亦即,形成被吊部之被吊板10b係以被吊板10b的外側端位於與折連板9形成同心圓形之一個圓的略圓周上(同一圓周上)之方式配置。並且,間隙維持件11係以間隙維持件11的外側端位於被吊板10b的外側端所形成之圓的略圓周上(同一圓周上)之方式配置。藉此,如後述之,藉由起重裝置吊起折連板9之際,即使折連板9因地震等的影響而於水平方向大幅位移,不僅是成為被吊部之折連支撐件10(被吊板10b),間隙維持件11亦與折連支撐件10一起碰撞於外槽的槽壁3,因而可使碰撞時的負擔分散。 That is, the suspended panel 10b forming the suspended portion is disposed such that the outer end of the suspended panel 10b is located on a substantially circumferential (same circumference) of a circle formed concentrically with the folding plate 9. Further, the gap maintaining member 11 is disposed such that the outer end of the gap maintaining member 11 is located on a substantially circumferential circumference (on the same circumference) of the circle formed by the outer end of the hanging plate 10b. As a result, as will be described later, when the folding plate 9 is lifted by the lifting device, even if the folding plate 9 is largely displaced in the horizontal direction due to the influence of an earthquake or the like, it is not only the folding support member 10 of the suspended portion. (The suspended plate 10b), the gap maintaining member 11 also collides with the folding support 10 to the groove wall 3 of the outer groove, so that the burden at the time of collision can be dispersed.

又,如第4、5圖中二點鎖鏈線所示,亦可將間隙維持件11的外側端以位於較被吊板10b的外側端更靠外側(外槽的側壁3側)之方式而形成配置。亦即,亦可以折連板9的中心至間隙維持件11的外側端的距離成為比折連板9的中心至被吊板10b的外側端的距離長之方式,形成配置間隙維持件11。此時,因藉由間隙維持件11可縮小外槽的側壁3與折連板9之間的實質的間隔,因此,藉由起重裝置吊起折連板9之際,即使折連板9因地震等的影響而於水平方向位移,亦可縮小位移量而緩和間隙維持件11碰撞外槽的側壁3之際的衝擊。 Further, as shown by the two-point chain line in FIGS. 4 and 5, the outer end of the gap maintaining member 11 may be located further outward than the outer end of the hanging plate 10b (the side of the side wall 3 of the outer groove). Form the configuration. In other words, the distance between the center of the folded plate 9 and the outer end of the gap maintaining member 11 may be set to be longer than the distance from the center of the connecting plate 9 to the outer end of the hanging plate 10b. At this time, since the gap between the side wall 3 of the outer groove and the folding plate 9 can be reduced by the gap maintaining member 11, the folding plate 9 is lifted even when the folding plate 9 is lifted by the lifting device The displacement in the horizontal direction due to the influence of an earthquake or the like can also reduce the displacement amount and alleviate the impact when the gap maintaining member 11 collides with the side wall 3 of the outer groove.

接著,如第7圖所示,於屋頂台架8上搭載內槽屋頂塊,組裝內槽屋頂(槽屋頂部)14。 Next, as shown in Fig. 7, an inner groove roof block is mounted on the roof gantry 8, and an inner tank roof (slot roof portion) 14 is assembled.

另外,將高處作業車(未圖示)開進基礎板1上。另外,為了於附腳台架6之下的環狀區域X形成環狀部16,將附 腳台架6的一部分施工。 In addition, a high-level work vehicle (not shown) is driven into the base plate 1. In addition, in order to form the annular portion 16 in the annular region X below the footrest 6, it will be attached. Part of the foot platform 6 is constructed.

另外,外槽的側壁3亦依序向上側積建,如第7圖所示,將外槽的側壁3施工至成為最終層之第九層(# 9)。又,在此時點,用於側壁3的形成之懸垂鷹架5係例如從第六層起維持於組裝在第七層以上之狀態而殘留。 Further, the side walls 3 of the outer tank are also sequentially stacked on the upper side, and as shown in Fig. 7, the side wall 3 of the outer tank is applied to the ninth layer (#9) which becomes the final layer. Moreover, at this point, the overhanging eagle 5 for forming the side wall 3 remains, for example, from the sixth layer while being assembled in the seventh layer or more.

接著,如第8圖所示,於折連板9上,從外槽的側壁3的內周面分離之狀態下,且在不與懸垂鷹架5干涉的高度,組裝起重裝置用鷹架17。起重裝置用鷹架17係沿著環狀地形成之折連板9的周方向而形成環狀,藉此,防止折連板9向半徑方向傾倒。另外,組裝起重裝置用鷹架17之際,在折連支撐件10支持起重裝置用鷹架17的略整體之狀態下,將傾倒防止材(未圖示)設於起重裝置用鷹架17與折連板9或內槽屋頂14之間。藉此,形成固定於折連板9或內槽屋頂14之起重裝置用鷹架17。本實施型態中,如第8圖所示,於外槽的側壁3的大約第四層(# 4)至第五層(# 5)對應之位置,組裝起重裝置用鷹架17。 Next, as shown in Fig. 8, the scaffolding plate 9 is assembled from the inner peripheral surface of the side wall 3 of the outer tub, and the scaffold for the lifting device is assembled at a height that does not interfere with the suspended scaffold 5. 17. The hoisting device 17 is formed in a ring shape along the circumferential direction of the folded-back plate 9 formed in an annular shape by the eagle frame 17, thereby preventing the folding plate 9 from falling in the radial direction. In addition, when the scaffolding support 10 is used to support the rig 1 of the hoisting device, the slanting prevention material (not shown) is placed on the hoist for the hoisting device. The frame 17 is interposed between the folding plate 9 or the inner groove roof 14. Thereby, the eagle frame 17 for the lifting device fixed to the folding plate 9 or the inner groove roof 14 is formed. In the present embodiment, as shown in Fig. 8, the gantry 17 for the lifting device is assembled at a position corresponding to the fourth layer (#4) to the fifth layer (#5) of the side wall 3 of the outer tub.

利用起重裝置用鷹架17,於側壁3的預定位置,本實施型態中係於第五層(# 5),以於側壁3的周方向等間隔的方式,設置複數個吊架台18(吊架部)。具體地,將吊架台18強固且可裝卸地締結固定於例如預先埋設於側壁3的錨板,藉以從側壁3朝向其內方以略水平地突出之方式設置。 In the present embodiment, the eagle frame 17 is attached to the fifth layer (#5) by the eagle frame 17 at the predetermined position of the side wall 3, and a plurality of hanger stations 18 are provided at equal intervals in the circumferential direction of the side wall 3. Hanger section). Specifically, the hanger table 18 is firmly and detachably attached to, for example, an anchor plate that is previously embedded in the side wall 3, so as to be provided to protrude slightly horizontally from the side wall 3 toward the inside thereof.

接著,分別於吊架台18與折連支撐件10的被吊板10b之間安裝起重裝置19。起重裝置19係如第9 圖所示,為中空式千斤頂,具有:耦合於吊架台18而被支持之千斤頂本體20a;上端部安裝於千斤頂本體20a,下端部安裝於折連支撐件10的被吊板10b之起重桿20;及用以將起重桿20的下端部安裝於被吊板10b的螺栓19a。又,第9圖中,為了容易觀看而省略了起重裝置用鷹架17的繪示。 Next, a lifting device 19 is attached between the hanger table 18 and the suspended panel 10b of the folding support 10, respectively. Lifting device 19 is like the ninth The figure shows a hollow jack having: a jack body 20a coupled to the hanger table 18; the upper end is mounted to the jack body 20a, and the lower end is attached to the lifting bar of the suspended plate 10b of the folding support 10 20; and a bolt 19a for attaching the lower end portion of the lifting rod 20 to the suspended plate 10b. Further, in Fig. 9, the illustration of the gantry 17 for the lifting device is omitted for easy viewing.

安裝起重裝置19之際,首先,使千斤頂本體20a耦合於吊架台18之上而固定狀態下,使起重桿20垂下,將起重桿20的下端部插入折連支撐件10的被吊板10b的缺口10d內。然後,藉由預先準備之螺栓19a將起重桿20的下端部固定於被吊板10b。 When the lifting device 19 is attached, first, the jack body 20a is coupled to the hanger table 18 in a fixed state, the lifting bar 20 is suspended, and the lower end portion of the lifting bar 20 is inserted into the folding support 10 to be suspended. Inside the notch 10d of the plate 10b. Then, the lower end portion of the mast 20 is fixed to the to-be-engaged plate 10b by the bolt 19a prepared in advance.

將複數個起重裝置19於外槽的側壁3的周方向以預定間隔設置,再分別將起重裝置19安裝於對應之折連支撐件10的被吊板10b之後,如第8圖所示,撤除屋頂台架8。藉此,成為槽構成構件的重量由複數個起重裝置19保持的狀態。 A plurality of lifting devices 19 are disposed at predetermined intervals in the circumferential direction of the side wall 3 of the outer tank, and the lifting device 19 is respectively attached to the suspended plate 10b of the corresponding folding support 10, as shown in FIG. , remove the roof gantry 8. Thereby, the weight of the groove constituent member is maintained by a plurality of lifting devices 19.

在此,如第8圖所示,吊架台18係設於對應側壁3的第五層(# 5)的位置,折連支撐件10係設於對應側壁3的第三層(# 3)的位置。起重桿20係形成為對應於吊架台18與折連支撐件10之間的長度之充分的長度。然而,如後述之,使起重裝置19驅動,使起重桿20上升之際,起重桿20係與位於其正上的懸垂鷹架5干涉。 Here, as shown in FIG. 8, the hanger table 18 is disposed at a position corresponding to the fifth layer (#5) of the side wall 3, and the folding support 10 is attached to the third layer (#3) of the corresponding side wall 3. position. The mast 20 is formed to a sufficient length corresponding to the length between the hanger table 18 and the folding support 10. However, as will be described later, when the lifting device 19 is driven to raise the mast 20, the mast 20 interferes with the overhanging eagle 5 located directly above it.

為了解決此問題,起重桿20係如第9圖所示,將複數個桿20b於長方向藉由螺鎖等可裝卸地連結而 藉以形成。 In order to solve this problem, the mast 20 is detachably coupled to the plurality of rods 20b in the longitudinal direction by a screw lock or the like as shown in FIG. By means of formation.

藉此,使起重桿20上升之際,藉由將突出於吊架台18上方的桿20b從其下側的桿20b分離,可防止起重桿20與懸垂鷹架5干涉。又,第8圖中的符號21係用以進行起重裝置19的各構成構件的吊起、垂降,將分離後之桿20b垂降的習知的懸吊天平,具有:天平棒21a及設於天平棒21a的一方的端部之重錘21b。懸吊天平21係藉由未圖示之吊車懸吊,藉此,控制升降、水平移動的各動作。 Thereby, when the lifting bar 20 is raised, the lifting bar 20 can be prevented from interfering with the overhanging eagle 5 by separating the rod 20b protruding above the hanger table 18 from the lower rod 20b. Further, reference numeral 21 in Fig. 8 is a conventional hanging balance for lifting and descending the respective constituent members of the lifting device 19, and the lever 20b is lowered, and has a balance bar 21a and The weight 21b provided at the end of one of the balance bars 21a. The suspension balance 21 is suspended by a crane (not shown), thereby controlling the respective movements of the lifting and the horizontal movement.

另外,如此的工程中,於基礎板1上並行地進行環狀部16的保冷工程及中央部的保冷工程。環狀部16的保冷工程中,如第9圖所示,於附腳台架6之下,底部冷熱阻抗緩和材22之上,組裝珍珠岩混凝土23a、23b、結構用輕量混凝土24,並於其之上安裝環狀板16a。環狀部16係最終地支持組裝後之內槽側板7。依此,環狀部16的環狀板16a係較厚地形成,另外,其保冷構造亦由混凝土塊等的硬質材料所形成。 Further, in such a project, the cold preservation project of the annular portion 16 and the cold preservation project at the center portion are performed in parallel on the base plate 1. In the cold preservation process of the annular portion 16, as shown in Fig. 9, under the footrest gantry 6, above the bottom cold heat and vibration absorbing material 22, perlite concrete 23a, 23b, lightweight concrete for structure 24 are assembled, and An annular plate 16a is mounted thereon. The annular portion 16 ultimately supports the assembled inner groove side panel 7. Accordingly, the annular plate 16a of the annular portion 16 is formed thickly, and the cooling structure is also formed of a hard material such as a concrete block.

接著,如第10圖所示,以起重裝置19吊起折連板9,藉此,使包含折連板9與被此支持之內槽屋頂14、內槽側板7、折連支撐件10、間隙維持件11、及起重裝置用鷹架17之槽構成構件Y上升。具體地,藉由使千斤頂本體20a正轉驅動,使起重桿20上升,與折連支撐件10一起舉重組裝途中的槽構成構件Y。 Next, as shown in Fig. 10, the folding plate 9 is lifted by the lifting device 19, whereby the inner panel 14 including the inner side groove 14, the inner groove side plate 7, and the folded support member 10 are supported. The gap maintaining member 11 and the groove forming member Y of the gantry 17 of the lifting device are raised. Specifically, the jack body 20a is driven to rotate forward, the jack 20 is raised, and the groove forming member Y in the middle of assembly is lifted together with the folding support 10.

在此,藉由起重裝置19吊起之折連板9係為了連接內槽屋頂14與內槽側板7,板厚係較內槽側板7 充分地厚而強度較高。依此,即使附加包含內槽側板7、內槽屋頂14,進一步地包含起重裝置用鷹架17的重量,亦不會屈曲。因此,下層側的內槽側板7係為了承受於槽完成後充填之內溶液之較大的液壓,板厚係較厚地形成,而上層側(特別是最上層)的內槽側板7係可承受內溶液之較小的液壓即可,板厚係較薄地形成。本實施型態中,因內槽側板7不屈曲,而可將內槽側板7形成上述之最佳設計,變得可輕量化及降低成本。 Here, the folding plate 9 hoisted by the lifting device 19 is for connecting the inner groove roof 14 and the inner groove side plate 7, and the plate thickness is compared with the inner groove side plate 7 Fully thick and strong. Accordingly, even if the inner groove side plate 7 and the inner groove roof 14 are additionally included, the weight of the gantry 17 for the lifting device is further included, and the buckling is not performed. Therefore, the inner groove side plate 7 on the lower layer side is formed to withstand a large hydraulic pressure of the solution after the completion of the groove, and the plate thickness is formed thickly, and the inner groove side plate 7 of the upper layer side (especially the uppermost layer) can withstand The smaller hydraulic pressure of the inner solution can be formed, and the thickness of the plate is formed thin. In the present embodiment, since the inner groove side plate 7 is not bent, the inner groove side plate 7 can be formed into the above-described optimum design, and the weight can be reduced and the cost can be reduced.

藉由起重裝置19使槽構成構件Y上升內槽側板7的大約一層分之後,於內槽側板的下方形成之空間,搬入次一層的內槽側板7,內槽側板7的搬入係經由設於側壁3的施工口4來進行。施工口4的周邊設有第一搬送裝置(未圖示),藉由第一搬送裝置,將內槽側板7依序從側壁3之外通過施工口4搬送至附腳台架6上。另外,附腳台架6上,沿著側壁3的周方向設有第二搬送裝置(未圖示)。第二搬送裝置係具有沿著側壁3的周方向之軌道(未圖示)等,將搬送至附腳台架6上的內槽側板7,再依序沿著側壁3的周方向搬送。 After the groove forming member Y is raised by about one layer of the inner groove side plate 7 by the lifting device 19, the space formed below the inner groove side plate is carried into the inner groove side plate 7 of the next layer, and the loading of the inner groove side plate 7 is set. This is carried out at the construction port 4 of the side wall 3. A first conveying device (not shown) is provided around the construction port 4, and the inner groove side plate 7 is sequentially conveyed from the outside of the side wall 3 through the construction port 4 to the footrest frame 6 by the first conveying device. Further, a second conveying device (not shown) is provided on the foot stand 6 along the circumferential direction of the side wall 3. The second conveying device has a rail (not shown) or the like along the circumferential direction of the side wall 3, and is conveyed to the inner groove side plate 7 on the footrest 6 and sequentially conveyed along the circumferential direction of the side wall 3.

接著,將第二搬送裝置搬送來之內槽側板7立設於附腳台架6上,於被舉起之內槽側板7的下方配置成圓環狀。然後,如第11圖所示,將橫方向相鄰之內槽側板7一體地熔接,並且將上下排列之內槽側板7彼此一體地熔接,藉以將內槽側板7形成一體的圓筒狀。亦即,於成為最上層之第九層(# 9)的內槽側板7之下,安裝第八層 (# 8)的內槽側板7。 Next, the inner groove side plate 7 that has been transported by the second conveying device is erected on the foot stand 6, and is disposed in an annular shape below the raised inner side plate 7. Then, as shown in Fig. 11, the inner groove side plates 7 adjacent in the lateral direction are integrally welded, and the inner groove side plates 7 arranged up and down are integrally welded to each other, whereby the inner groove side plates 7 are formed into an integral cylindrical shape. That is, the eighth layer is installed under the inner groove side plate 7 which becomes the ninth layer (#9) of the uppermost layer. (#8) The inner groove side plate 7.

又,亦可將複數個內槽側板7彼此預先於外槽的側壁3之外橫向連結,將其送進側壁3內,形成環狀之後,再將上下排列之內槽側板7彼此熔接。如此,將複數個內槽側板7的橫向的連結於作業空間的限制較少的側壁3之外進行,藉此,熔接作業變得容易,而可效率良好地組裝內槽。 Further, a plurality of the inner groove side plates 7 may be laterally connected to each other in advance of the outer side wall 3 of the outer groove, and fed into the side wall 3 to form a ring shape, and then the inner groove side plates 7 arranged up and down are welded to each other. In this manner, the lateral direction of the plurality of inner-groove side plates 7 is connected to the outside of the side wall 3 having a small restriction on the working space, whereby the welding work can be easily performed, and the inner grooves can be efficiently assembled.

如此地進行舉起,則如第11圖所示,起重裝置19的起重桿20的上端係從吊架台18向上方突出。若起重桿20更上升至其之上,則會與位於其正上方的懸垂鷹架5干涉。對此,在進行內槽側板7彼此的熔接等之期間,構成起重桿20之複數個桿20b之中,將從吊架台18向上方突出之桿20b拆除。拆除後之桿20b係藉由予先設置於起重裝置用鷹架17的頂部之吊架(未圖示),垂降至內槽屋頂14上。桿20b的拆除係利用起重裝置用鷹架17而進行。另外,為了使起重裝置用鷹架17不干涉懸垂鷹架5,藉由吊天平21依序將起重裝置用鷹架17的上部側撤除。 When lifted in this manner, as shown in Fig. 11, the upper end of the lifting bar 20 of the lifting device 19 protrudes upward from the hanger base 18. If the lifting bar 20 rises above it, it will interfere with the overhanging eagle 5 located directly above it. On the other hand, during the welding of the inner-groove side plates 7 and the like, among the plurality of rods 20b constituting the mast 20, the rods 20b projecting upward from the hanger table 18 are removed. The detached rod 20b is lowered onto the inner tank roof 14 by a hanger (not shown) previously provided on the top of the gantry 17 for the hoisting device. The removal of the rod 20b is performed by the scaffold 17 using a lifting device. Further, in order to prevent the hoisting device 17 from interfering with the overhanging eagle frame 5, the hoisting device 21 sequentially removes the hoisting device 17 from the upper side of the eagle frame 17.

接著,藉由起重裝置19使槽構成構件Y上升內槽側板7的大約一層分,於內槽側板7的下方形成之空間,搬入再次一層的內槽側板7。與前述第八層(# 8)的內槽側板7的安裝同樣地,如第12圖所示,安裝第七層(# 7)的內槽側板7。此時,亦拆除從吊架台18向上方突出之桿20b,藉由懸吊天平21垂降於內槽屋頂14上。 Then, the lifting device 19 raises the groove forming member Y by about one layer of the inner groove side plate 7, and the space formed below the inner groove side plate 7 carries the inner groove side plate 7 of the other layer. Similarly to the mounting of the inner groove side plate 7 of the eighth layer (#8), as shown in Fig. 12, the inner groove side plate 7 of the seventh layer (#7) is attached. At this time, the rod 20b protruding upward from the hanger table 18 is also removed, and the suspension balance 21 is lowered onto the inner tank roof 14.

如此地安裝第九層(# 9)至第七層(# 7)的內 槽側板7之後,如第13圖所示,拆除側壁3的內周面側的懸垂鷹架5。通常,安裝第九層(# 9)至第七層(# 7)的內槽側板7之期間,外槽的側壁3係完成至成為最上層之第九層(# 9)。依此,可拆除用以形成側壁3的模板等,因而可撤除位於側壁3的內周面側的懸垂鷹架5。又,關於側壁3的外周面側的鷹架等,因其後的工程尚需使用,因此不撤除而保留。 Install the ninth layer (# 9) to the seventh layer (# 7) in this way After the groove side plate 7, as shown in Fig. 13, the overhanging eagle 5 on the inner peripheral surface side of the side wall 3 is removed. Usually, during the installation of the inner groove side plates 7 of the ninth layer (#9) to the seventh layer (#7), the side walls 3 of the outer grooves are completed to the ninth layer (#9) which is the uppermost layer. According to this, the template or the like for forming the side wall 3 can be removed, and thus the overhanging eagle 5 located on the inner peripheral side of the side wall 3 can be removed. Further, the scaffold or the like on the outer peripheral surface side of the side wall 3 is required to be used for the subsequent work, and therefore it is retained without being removed.

接著,為了進行起重裝置19的移位重設,如第13圖所示,於外槽的側壁3的頂部,設置第二吊架台25。另外,暫時地將槽構成構件Y(亦包含第八層、第七層的內槽側板7等)下降而降下於附腳台架6上。 Next, in order to perform displacement resetting of the lifting device 19, as shown in Fig. 13, a second hanger table 25 is provided at the top of the side wall 3 of the outer tub. Further, the groove constituent member Y (including the eighth groove, the inner groove side plate 7 of the seventh layer, and the like) is temporarily lowered and lowered on the foot stand 6.

接著,如第9圖所示,利用懸吊天平21、吊車等,將起重裝置19的起重桿20暫時從折連支撐件10的被吊板10b拆除。另外,將起重裝置19的千斤頂本體20a從吊架台18拆除。藉此,起重裝置19係從外槽的側壁3與折連板9之間拆除。再者,將吊架台18從側壁3拆除。 Next, as shown in Fig. 9, the lifting bar 20 of the lifting device 19 is temporarily removed from the suspended plate 10b of the folding support 10 by means of a suspension balance 21, a crane or the like. Further, the jack body 20a of the lifting device 19 is detached from the hanger table 18. Thereby, the lifting device 19 is removed from between the side wall 3 of the outer tank and the folding plate 9. Furthermore, the hanger table 18 is removed from the side wall 3.

然後,將起重裝置19的千斤頂本體20a安裝於第13圖所示之第二吊架台25。另外,先前的工程中,為了不干涉懸垂鷹架5而暫時地拆除起重桿20的上部側,並垂降置於內槽屋頂14上。然而,藉由撤除側壁3的內周面側的懸垂鷹架5而可自由地延伸起重桿20,因此,再次將垂降置於內槽屋頂14上的桿20b安裝於起重桿20而增長起重桿20。本實施型態中,如第13圖所示,為了使起重桿20從成為外槽的側壁3的最上層之第九層(# 9)垂降 至第五層(# 5),因而更附加補充另外準備的預備的桿20b以將起重桿20調整為預定的長度。 Then, the jack body 20a of the lifting device 19 is attached to the second hanger table 25 shown in Fig. 13. Further, in the prior art, the upper side of the mast 20 was temporarily removed in order not to interfere with the overhanging eagle 5, and the sag was placed on the inner trough roof 14. However, the hoisting rod 20 can be freely extended by removing the overhanging eagle 5 on the inner peripheral surface side of the side wall 3, and therefore, the rod 20b on which the sag is placed on the inner tank roof 14 is attached to the lifting rod 20 again. Increase the lifting rod 20. In the present embodiment, as shown in Fig. 13, in order to cause the lifting bar 20 to descend from the ninth layer (#9) which is the uppermost layer of the side wall 3 which becomes the outer groove Up to the fifth layer (#5), it is thus additionally supplemented with a separately prepared preliminary rod 20b to adjust the lifting rod 20 to a predetermined length.

如此,將起重桿20調整為預定的長度之後,將起重桿20的下端側再次插入折連支撐件10的被吊板10b的缺口10d內。然後,藉由螺栓19a將起重桿20的下端部固定於被吊板10b。藉此,位移起重裝置19。如此地完成起重裝置19的移位重設之後,如第13圖所示,撤除起重裝置用鷹架17。 In this manner, after the lifting bar 20 is adjusted to a predetermined length, the lower end side of the lifting bar 20 is again inserted into the notch 10d of the hanging plate 10b of the folding support 10. Then, the lower end portion of the mast 20 is fixed to the to-be-engaged plate 10b by the bolt 19a. Thereby, the lifting device 19 is displaced. After the shift reset of the lifting device 19 is completed in this manner, as shown in Fig. 13, the crane 17 for the lifting device is removed.

接著,如第14圖所示,以起重裝置19吊起折連板9,使槽構成構件Y上升內槽側板7的大約一層分。 Next, as shown in Fig. 14, the folding plate 9 is lifted by the lifting device 19, and the groove constituent member Y is raised by about one layer of the inner groove side plate 7.

接著,於內槽側板7的下方形成之空間,搬入再次一層的內槽側板7,以下,與前述第八層(# 8)、第七層(# 7)的內槽側板7的安裝同樣地,如第15圖所示,安裝第六層(# 6)的內槽側板7。 Then, the space formed below the inner groove side plate 7 is carried into the inner groove side plate 7 of the other layer, and is similarly attached to the inner groove side plate 7 of the eighth layer (#8) and the seventh layer (#7). As shown in Fig. 15, the inner groove side plate 7 of the sixth layer (#6) is installed.

接著,於內槽屋頂14之上安裝外槽屋頂26。外槽屋頂26的安裝係於內槽屋頂14上安裝多數個管道型鋼等所成之連結材(未圖示),並於這些連結材安裝外槽屋頂26而進行。 Next, an outer trough roof 26 is installed over the inner trough roof 14. The attachment of the outer tank roof 26 is performed by attaching a plurality of joints (not shown) formed of a plurality of duct steels to the inner tank roof 14, and attaching the outer tank roof 26 to the joints.

另外,對於外槽的側壁3的內周面,開始貼設側部襯料(未圖示)之作業。 Moreover, the operation of attaching a side lining (not shown) to the inner peripheral surface of the side wall 3 of the outer tank is started.

以下,依序反覆進行藉由起重裝置19之槽構成構件Y的上升、對於內槽側板7(槽構成構件Y)的下方之次一層的內槽側板7的搬入、及搬入之內槽側板7對於的槽構成構件Y(內槽側板7)的安裝,如第16圖所示,將 內槽側板7安裝至最下層的第一層(# 1)為止。藉此完成內槽的側壁。 In the following, the rise of the groove constituent member Y by the lifting device 19, the loading of the inner groove side plate 7 of the next layer below the inner groove side plate 7 (the groove forming member Y), and the insertion of the inner groove side plate are sequentially performed. 7 The installation of the groove constituting member Y (the inner groove side plate 7), as shown in Fig. 16, will The inner groove side plate 7 is attached to the first layer (#1) of the lowermost layer. Thereby the side walls of the inner tank are completed.

又,如此的各層的內槽側板7的安裝之際,亦即,吊起槽構成構件Y,其下方成為空間之期間,有別於內槽側板7的搬入,將各種資材27搬入至側壁.3內的基礎板1上。另外,於外槽屋頂26之上組裝設置作業鷹架28。 Moreover, when the inner-groove side plate 7 of each layer is attached, that is, the groove-constituting member Y is lifted, the space below the space is formed, and the inner-groove side plate 7 is carried in, and the various materials 27 are carried into the side wall. 3 on the base board 1 inside. In addition, an operating scaffolding 28 is assembled on the outer trough roof 26.

接著,如第17圖所示,撤除附腳台架6,使槽構成構件Y的下方成為空間。然後,藉由起重裝置19將槽構成構件Y降下,並將外槽屋頂26的屋頂骨12的外周端連結固定於外槽的側壁3的頂部內周面埋設的安裝端。 Next, as shown in Fig. 17, the foot stand 6 is removed, and the lower portion of the groove forming member Y becomes a space. Then, the groove constituting member Y is lowered by the lifting device 19, and the outer peripheral end of the roof bone 12 of the outer tank roof 26 is joined and fixed to the mounting end of the top inner peripheral surface of the side wall 3 of the outer tank.

接著,將連結外槽屋頂26與內槽屋頂14之間的連結材(未圖示)除去,解除其之間的連結。 Next, the connecting material (not shown) connecting the outer tank roof 26 and the inner tank roof 14 is removed, and the connection therebetween is released.

接著,如第18圖所示,藉由起重裝置19再次將槽構成構件Y降下,將內槽側板7的最下層的下端部降至環狀部16上。然後,將內槽側板7的最下層的下端部安裝於基礎板1所設置之內槽錨箍2。 Next, as shown in Fig. 18, the groove constituting member Y is lowered again by the lifting device 19, and the lower end portion of the lowermost layer of the inner groove side plate 7 is lowered to the annular portion 16. Then, the lower end portion of the lowermost layer of the inner groove side plate 7 is attached to the inner groove anchor 2 provided in the base plate 1.

接著,從折連板9除去折連支撐件10,再者,對應必要的情況,除去間隙維持件11。 Next, the folding support 10 is removed from the folding plate 9, and the gap maintaining member 11 is removed as necessary.

之後,進行外槽的側壁3的拉緊工程。另外,對於貼設在外槽的側壁3的內周面之側部襯料(未圖示),噴附冷熱阻抗緩和材之聚氨酯發泡材(PUF)。再者,將起重裝置19、第二吊架台25等撤除。然後,封閉施工口4,設置未圖示的泵筒並且灌水,實施耐壓、氣密試驗。 最後,於內槽與外槽之間填充珍珠岩等的保冷材(未圖示),進行外槽間保冷工程。在進行塗裝工程、配管保冷工程之後,完成圓筒型槽100。 Thereafter, the tensioning of the side wall 3 of the outer tank is performed. Further, a urethane foam (PUF) of a cold heat-resistance-reducing material is sprayed on a side lining (not shown) attached to the inner peripheral surface of the side wall 3 of the outer tub. Furthermore, the lifting device 19, the second hanger table 25, and the like are removed. Then, the construction port 4 is closed, a pump cylinder (not shown) is installed and water is poured, and a pressure resistance and airtightness test are performed. Finally, a cold-retaining material (not shown) such as perlite is filled between the inner tank and the outer tank, and the outer tank is kept cold. After the coating work and the piping cold preservation project, the cylindrical tank 100 is completed.

構築如此構成的圓筒型槽100之際,特別是在藉由起重裝置19使槽構成構件Y舉起之間,或使之懸垂之間,若發生地震或強風等,會有內槽屋頂14、外槽屋頂26等在外槽內於水平方向大幅位移的可能性。然而,本實施型態中,如第4至6圖所示,於折連板9的外周面設有間隙維持件11。藉此,即使折連板9(槽構成構件Y)於水平方向位移,因不僅是成為被吊部之折連支撐件10(被吊板10b),間隙維持件11亦碰撞外槽的側壁3,因而可使碰撞時的負擔分散。 When the cylindrical groove 100 having the above-described configuration is constructed, particularly between the lifting of the groove forming member Y by the lifting device 19 or between the suspensions, if an earthquake or strong wind occurs, there is an inner groove roof. 14. The possibility that the outer trough roof 26 and the like are largely displaced in the horizontal direction in the outer tank. However, in the present embodiment, as shown in Figs. 4 to 6, the gap maintaining member 11 is provided on the outer peripheral surface of the folding plate 9. Thereby, even if the folding plate 9 (the groove forming member Y) is displaced in the horizontal direction, the gap maintaining member 11 also collides with the side wall 3 of the outer groove because the folding support member 10 (the hanging plate 10b) is not the hanging portion. Therefore, the burden at the time of collision can be dispersed.

依此,若依據本實施型態的圓筒型槽的構築方法,即使於舉起時,折連板9(槽構成構件Y)因地震等於水平方向位移,間隙維持件11係與折連支撐件10一起碰撞外槽的側壁3,因而可使碰撞時的負擔分散。可防止因負擔集中造成之外槽的側壁3的破壞。 According to this, according to the construction method of the cylindrical groove of the present embodiment, even when the lifting, the folding plate 9 (the groove forming member Y) is displaced in the horizontal direction due to the earthquake, the gap maintaining member 11 and the folding support are supported. The pieces 10 collide with the side wall 3 of the outer groove together, so that the burden at the time of collision can be dispersed. It is possible to prevent the destruction of the side wall 3 of the groove due to the concentration of the load.

另外,將間隙維持件11分別配置於相鄰之折連支撐件10、10間。亦即,折連支撐件10係位於相鄰之間隙維持件11、11間。依此,折連板9(槽構成構件Y)於水平方向位移,碰撞側壁3之際,可藉由相鄰之間隙維持件11、11來保護位於其之間的折連支撐件10,防止起重裝置19與被吊板10b(被吊部)之間損傷。 Further, the gap maintaining members 11 are disposed between the adjacent folding supports 10 and 10, respectively. That is, the folding support 10 is located between the adjacent gap maintaining members 11, 11. Accordingly, the folding plate 9 (the groove forming member Y) is displaced in the horizontal direction, and when the side wall 3 is collided, the adjacent supporting members 10, 11 can be used to protect the folding support 10 between them The lifting device 19 is damaged between the suspended plate 10b and the suspended portion 10b.

另外,以折連部9的中心至間隙維持件11 的外側端的距離成為大於折連部9的中心至被吊板10b(折連支撐件10)的外側端的距離的長度之方式,配置間隙維持件11。藉此,與側壁3的碰撞之際,間隙維持件11必定會碰撞側壁3,因而可確實地防止起重裝置19與被吊板10b(被吊部)之間損傷。 In addition, the center of the folded portion 9 to the gap maintaining member 11 The gap support member 11 is disposed such that the distance of the outer end is greater than the length of the center of the folded portion 9 to the outer end of the hanging plate 10b (the folded support 10). Thereby, the collision maintaining member 11 necessarily hits the side wall 3 at the time of collision with the side wall 3, so that damage between the lifting device 19 and the suspended plate 10b (the suspended portion) can be surely prevented.

另外,將複數個被吊板10b(折連支撐件10)的外側端配置於同一圓周上,並將間隙維持件11的外側端配置於與被吊板10b的外側端形成之圓周為同一圓周上。藉此,與側壁3的碰撞之際,相鄰之間隙維持件11與折連支撐件10大約同時地與側壁3碰撞,因而可提高碰撞時的負擔分散效果。 Further, the outer ends of the plurality of suspended plates 10b (the folded support members 10) are disposed on the same circumference, and the outer ends of the gap maintaining members 11 are disposed on the same circumference as the circumference formed by the outer ends of the suspended plates 10b. on. Thereby, the collision between the adjacent gap maintaining member 11 and the folding support 10 collides with the side wall 3 at the same time as the collision with the side wall 3, so that the burden dispersion effect at the time of collision can be improved.

另外,以折連部9的中心至間隙維持件11的外側端的距離成為大於折連部9的中心至被吊板10b(折連支撐件10)的外側端的距離的長度之方式,配置間隙維持件11的情況時,藉由間隙維持件11可縮小外槽的側壁3與折連板9之間的實質的間隔。依此,即使折連板9因地震等的影響而於水平方向位移,亦可縮小折連板9的位移量。藉此,可緩和間隙維持件11碰撞外槽的側壁3之際的衝擊,防止外槽的側壁3的損傷。另外,亦可確實地防止起重裝置19與被吊板10b(被吊部)之間損傷。 Further, the distance between the center of the folded portion 9 and the outer end of the gap maintaining member 11 is set to be larger than the length of the center of the folded portion 9 to the outer end of the hanging plate 10b (the folded support 10). In the case of the member 11, the substantial spacing between the side wall 3 of the outer groove and the folding plate 9 can be reduced by the gap maintaining member 11. According to this, even if the folding plate 9 is displaced in the horizontal direction due to the influence of an earthquake or the like, the displacement amount of the folding plate 9 can be reduced. Thereby, the impact when the gap maintaining member 11 collides with the side wall 3 of the outer tub can be alleviated, and the damage of the side wall 3 of the outer tub can be prevented. Further, it is possible to surely prevent damage between the lifting device 19 and the suspended plate 10b (the suspended portion).

另外,組裝折連板9之工程中,於預先組裝之內槽側板7的上側安裝折連板9。若於最初將向高度方向彎曲之折連板9組裝成圓環狀,則藉此,將可容易地將不向高度方向彎曲之內槽側板7組裝成圓環狀,而於之後 再將折連板9安裝於內槽側板7。依此,折連板9的組裝可變得容易。 Further, in the process of assembling the folding plate 9, the folding plate 9 is attached to the upper side of the pre-assembled inner groove side plate 7. When the connecting plate 9 which is bent in the height direction is initially assembled into an annular shape, the inner groove side plate 7 which is not bent in the height direction can be easily assembled into an annular shape, and thereafter The folding plate 9 is attached to the inner groove side plate 7. Accordingly, the assembly of the flaps 9 can be facilitated.

另外,於折連板9的下側安裝內槽側板7以組裝金屬製的內槽之工程中,進行:於吊架台18垂吊起重裝置19,舉起槽構成構件Y之處理;以及在吊架台18的上方設置第二吊架台25並位移起重裝置19,在其狀態下舉起槽構成構件Y之處理。在任一處理中,藉由設置間隙維持件11,可防止內槽屋頂側或外槽等損壞。 Further, in the process of attaching the inner groove side plate 7 to the lower side of the connecting plate 9 to assemble the inner groove of the metal, the lifting device 19 is suspended from the hanger table 18, and the processing of the groove forming member Y is lifted; A second hanger table 25 is disposed above the hanger table 18 and the lifting device 19 is displaced, and the process of lifting the groove forming member Y is performed in this state. In any of the processes, by providing the gap maintaining member 11, damage to the roof side or the outer groove of the inner groove can be prevented.
