を二重にライニングした構造のライニング貯槽に
関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a lined storage tank, such as a large concrete storage tank, which has a structure in which the surface of a concrete wall is double-lined with a metal lining plate and a shield plate.
コンクリート貯槽の壁面を金属ライニングした

Lined storage tanks, in which the walls of concrete storage tanks are lined with metal, are widely used, for example, in facilities that handle radioactive waste liquid related to nuclear power plants or in general chemical plants.

を二重にライニングしたライニング貯槽の構造を
説明する。 Below, referring to Figure 1, we will explain how concrete walls used in nuclear fuel storage pools or radioactive waste liquid storage tanks in nuclear power plant facilities are double-lined with stainless steel lining plates and carbon steel shield plates. The structure of the lined storage tank will be explained.
すなわち、第１図はライニング貯槽の要部のみ

なお、図中符号６は鉄筋を示している。 That is, FIG. 1 partially shows only the essential parts of the lining storage tank, and as is clear from FIG. It covers the entire surface as if it were a single board. Here, lining board 1 has a single size of 1.5m x 3
2 m x 6 m, etc., and are fixed by welding via the backing metal 3 as described above when welding the lining plates 1 together. Therefore, the backing metal 3 is fixed to the concrete 7 with the anchor bolts 5 via the base material 4.
Note that the reference numeral 6 in the figure indicates a reinforcing bar.
しかし通常のライニング板については接続部の
溶接線の他に第１図ロに示したようにライニング
板１に孔１０を開け栓溶接１１によつてシールド
板２と溶接されてライニング板１のふくらみを防
止している。 However, in the case of a normal lining plate, in addition to the weld line at the connection part, a hole 10 is made in the lining plate 1 and the shield plate 2 is welded by plug welding 11 as shown in FIG. is prevented.
第１図イ，ロにおけるシールド板２は通常安価
で加工性の良い炭素鋼を使用しており、ライニン
グ板１と材質が異る場合が殆んどである。そのた
め栓溶接部１１は異材溶接となり溶接が困難にな
る欠点があつた。 The shield plate 2 shown in FIGS. 1A and 1B is usually made of carbon steel, which is inexpensive and has good workability, and is almost always made of a different material from the lining plate 1. As a result, the plug welded portion 11 is welded with different materials, which has the drawback of making welding difficult.
またシールド板２をライニング板１と同材質の
たとえばステンレス鋼とするには大変高価なもの
となり、産業上からも合理的でない。 Furthermore, if the shield plate 2 is made of the same material as the lining plate 1, such as stainless steel, it will be very expensive and not industrially reasonable.

複雑で手間を要するなどの欠点があつた。 Furthermore, for other methods such as providing a backing metal 3 on the plug welded part 11 as shown in FIG.
In addition, it is necessary to provide a base material 4, which requires cutting the shield plate 2 into thin pieces, which is complicated and time-consuming.

The present invention was made in order to eliminate the drawbacks of the conventional lined storage tank described above, by making holes in the shield plate and welding studs made of the same material as the lining plate directly to the lining plate. An object of the present invention is to provide a lining storage tank which enables effective fixing of a lining plate with good weldability by closing with a washer.

That is, the present invention provides a lined storage tank in which a concrete wall is double lined with a lining plate and a shield plate, in which a stud made of the same material as the lining plate is connected to the back side of the lining plate,
This lining storage tank is characterized in that a washer is provided on the stud, and the washer and the shield plate are fixed by welding.
以下、第２図により本考案の一実施例を説明す

る。 In FIG. 2, studs 8 made of the same material as the lining plate 1 are welded and fixed to the back surface of the lining plate 1. Next, the shield plate 2 in which the through holes 10 have been previously opened is brought into contact with the back surface of the lining plate 1, and at this time, the through holes 10 are inserted into the studs 8. Then, a washer 9 having a shape slightly larger than the outer diameter of the stud 8 and whose outer periphery is slightly larger than the through hole 10 of the shield plate 2 is inserted into the stud 8. A through hole 12 into which the stud 8 is inserted is provided in the center of the washer 9. The vicinity of the through hole 12 provided in the washer 9, the side surface of the stud, the outer peripheral surface of the washer 9, and the shield plate 2 are each watertightly welded and fixed.
なお、スタツド８の上方にはねじ８ａが加工し

2, and extend a screw 8b on the surface of the stud 8 to a length that will be screwed into it. After welding the stud 8 and the lining plate 1, screw the washer 9 into the stud 8 and connect the shield plate 2 and the lining. After the plates 1 are brought into close contact with each other, the inner and outer circumferential surfaces of the washer 9 may be welded, respectively.
さらにスタツド８は一端にねじ加工して、セパ

案の変形とすることができる。 Further, the stud 8 is threaded at one end to be fastened to the separator, but it is also possible to use an ordinary stud dowel or anchor bolt as a modification of the present invention.
本考案によれば次のような効果がある。 The present invention has the following effects.
(1) 栓溶接の為の孔開け加工はライニング板に加
工する必要がないので加工のためにライニング
板を移動することがなくライニング板の表面に
傷をつけるなどの不都合を避けることができ
る。(1) Holes for plug welding do not require processing on the lining plate, so there is no need to move the lining plate for processing, and inconveniences such as damage to the surface of the lining plate can be avoided.
(2) ステンレス鋼のライニング板に対する孔開け
より炭素鋼のシールド板に対する孔開け加工は
より容易であり孔開け加工時間は少くて良い。(2) Drilling holes in a carbon steel shield plate is easier than drilling holes in a stainless steel lining plate, and requires less time for drilling holes.
(3) 栓溶接による溶接部分がライニング板を貫通
してないので溶接の欠陥によつてライニング貯
槽内の液体が外部へ漏れる等の不具合が発生し
ない。(3) Since the welded part by plug welding does not penetrate the lining plate, problems such as leakage of liquid in the lining storage tank to the outside due to welding defects will not occur.
(4) ライニング板表面上に溶接部が現れないので
グラインダーで溶接部の表面を平滑に仕上げた
りする必要がなく、外観がよく手間がかからな
い。(4) Since the welds are not visible on the surface of the lining plate, there is no need to grind the surface of the welds to a smooth finish, resulting in a good appearance and less hassle.
(5) ライニング板とスタツドは同材質とすること
により溶接性の良いものとなり溶接が容易にで
きる。(5) By making the lining plate and the studs the same material, they have good weldability and can be easily welded.
(6) 栓溶接の有する個所に裏当金を設けるものに
比較しては下地材の構造が簡略化され栓溶接の
個所や位置は任意に選択できる。(6) Compared to the case where a backing metal is provided at the location of plug welding, the structure of the base material is simplified, and the location and location of plug welding can be selected arbitrarily.
(7) スタツドをセパレータ用金具と兼用できるた
め、製作費用が安価となりかつライニング板を
直接固定する為機能的にも優れたものとなる等
の多大な効果がある。(7) Since the studs can also be used as separator fittings, the manufacturing cost is low, and since the lining plate is directly fixed, the studs are functionally superior and have great effects.
