In the above figures, (1) is a pressure vessel wall, (2) is a backing plate, (3) is the pressure vessel wall (1), a fillet weld that joins the backing plate (2), (4) shows a butt-welded portion that joins the pressure vessel wall body (1).
次に作用について説明する。Next, the operation will be described.
従来の圧力容器は折り曲げた鋼板を溶接接合して製作さ
れていた。この突き合わせ溶接の位置は特に考慮せず
に、例えば第４図の例に示すように十分な溶接強度を有
する方法をとっていた。A conventional pressure vessel is manufactured by welding and joining bent steel plates. The position of this butt welding was not particularly considered, and a method having sufficient welding strength was adopted as shown in the example of FIG. 4, for example.
従来は第４図に示される様に、圧力容器壁体(1)の接合

め、容器製作時の溶接作業の手間がかかる、また、当て
板(2)の分だけ、材料が多く必要であるなどの問題点が
あった。Conventionally, as shown in FIG. 4, since the pressure vessel is reinforced by joining the backing plate (2) to the joint portion of the pressure vessel wall body (1), it takes a lot of time and labor for welding when producing the vessel. Also, there is a problem that a large amount of material is required for the backing plate (2).
この考案は、上記の様な問題点を解消するためになされ
たもので、当て板(2)を使用して容器を補強しなくて
も、充分強度のある矩形圧力容器を得ることを目的とす
る。The present invention has been made to solve the above problems, and an object thereof is to obtain a rectangular pressure vessel having sufficient strength without reinforcing the vessel by using a backing plate (2). To do.
この考案に係る矩形圧力容器は、コーナー間の応力の最
も小さい箇所を選んで突き合わせ溶接をしたものであ
る。In the rectangular pressure vessel according to the present invention, butt welding is performed by selecting the place where the stress between the corners is the smallest.
この考案における矩形圧力容器は、コーナー間の応力の
最も小さい箇所を選んで突き合わせ溶接することによ
り、溶接部にかかる応力を小さくする。In the rectangular pressure vessel according to the present invention, the stress applied to the welded portion is reduced by selecting and butt-welding the place where the stress between the corners is the smallest.
以下、この考案の一実施例を図について説明する。第１
図は、この考案の一実施例である矩形圧力容器の水平方
向の断面を示す図である。An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 is a diagram showing a horizontal cross section of a rectangular pressure vessel according to an embodiment of the present invention.
第１図において、(1)は圧力容器壁体、(4)は圧力容器壁
体(1)を接合している突き合わせ溶接部を示すものであ
る。このようにして矩形圧力容器(5)が製作される。In FIG. 1, (1) shows a pressure vessel wall body, and (4) shows a butt welding portion joining the pressure vessel wall body (1). In this way, the rectangular pressure vessel (5) is manufactured.
第１図において、大気圧以上の媒体を封入したときの矩
形圧力容器(5)の一辺Ａに加わる荷重は、第２図に示す
ように等分布荷重となる。ｗは媒体の圧力である。In FIG. 1, the load applied to one side A of the rectangular pressure vessel (5) when a medium at atmospheric pressure or higher is enclosed becomes a uniformly distributed load as shown in FIG. w is the pressure of the medium.
また、第３図にこのときの辺Ａに加わる曲げモーメント
の分布を示す。辺Ａの長さがの場合、主要な点での曲
げモーメント及び曲げモーメントが零となる点の位置は
図のようになる。Further, FIG. 3 shows the distribution of the bending moment applied to the side A at this time. When the length of the side A is, the bending moment at the main points and the positions of the points where the bending moment becomes zero are as shown in the figure.
したがって、第３図において曲げモーメントが零となる
点、つまりＰまたはＱ、が最も容器に加わる応力の小さ
い点となる。Therefore, in FIG. 3, the point where the bending moment becomes zero, that is, P or Q is the point where the stress applied to the container is the smallest.
よって、この点またはこの近傍、すなわちコーナー端か
ら辺Ａの長さ約５分の１だけ辺Ａの中央寄りの位置を突
き合わせ溶接部(4)にすれば、溶接部(4)に加わる応力を
最も小さくすることができる。その結果、圧力容器の弱
点部である接合部の強度を相対的に高めることができる
ので矩形圧力容器(5)の信頼性を高くすることができ
る。Therefore, if the butt-welding portion (4) is located at or near this point, that is, the position near the center of the side A by about 1/5 of the length of the side A from the corner end, the stress applied to the welding portion (4) is reduced. Can be the smallest. As a result, the strength of the joint, which is the weak point of the pressure vessel, can be relatively increased, and the reliability of the rectangular pressure vessel (5) can be increased.
なお、上記実施例では、圧力容器壁体(1)を突き合わせ
溶接した例を示したが、圧力容器壁体(1)を溶接部で重
ね合わせ、この部分をスミ肉溶接しても上記実施例と同
様の効果を奏する。In the above embodiment, the pressure vessel wall body (1) was shown as an example of butt welding, but the pressure vessel wall body (1) is overlapped at the welded portion, and even if this portion is fillet welded Has the same effect as.
以上の様に、この考案によれば、応力の最も小さい箇所
を溶接部としたため、溶接部にかかる応力を小さくする
ことができ、簡単な構成で信頼性の高い矩形圧力容器が
得られるという効果がある。As described above, according to the present invention, since the portion with the smallest stress is the welded portion, the stress applied to the welded portion can be reduced, and a highly reliable rectangular pressure vessel can be obtained with a simple configuration. There is.
