Description

【考案の詳細な説明】本考案は液体等を貯蔵するタンクの底板構造に
関する。[Detailed Description of the Invention] The present invention relates to a bottom plate structure of a tank for storing liquid or the like.

従来のタンクの底板は第１図及び第２図に示し
たように平板を敷き並べ、互いに隣接する端部を
突合せ溶接（第２図のａ部）又は重ね隅肉溶接
（第２図のｂ部）してなる構造である。しかし、
この構造のタンクの底板は溶接による金が発生し
て底板全体が凹凸し、液深が上下した時凹凸部が
繰り返し応力を受ける欠点がある。 The bottom plate of a conventional tank is made of flat plates arranged in rows as shown in Figures 1 and 2, and the adjacent ends are butt welded (section a in Figure 2) or lap fillet welded (section b in Figure 2). The structure consists of but,
The bottom plate of a tank with this structure has the disadvantage that the entire bottom plate is uneven due to the generation of gold due to welding, and the uneven parts are subject to repeated stress when the liquid depth rises and falls.

本考案はこのような従来のタンクの底板構造の
欠点を改善する目的でなされたものである。すな
わち、本考案のタンクの底板は第３図及び第４図
に示したように断面がＬ型の短冊状薄板を並列に
配列し、互いに隣接する縁頂部を隅肉溶接してな
る構造であり、溶接による歪が発生しないので有
害な凹凸が発生しない。 The present invention has been made to improve the drawbacks of the conventional tank bottom plate structure. That is, the bottom plate of the tank of the present invention has a structure in which strip-shaped thin plates with an L-shaped cross section are arranged in parallel and the adjacent edge tops are fillet welded, as shown in FIGS. 3 and 4. Since no distortion occurs due to welding, harmful unevenness does not occur.

以下、本考案を具体的に説明する。 The present invention will be explained in detail below.

タンクの底板をコイル状で現地に搬入し、ロー
ル成型機でコイルを第５図の如くＬ型に成型す
る。次に、この成型された底板を第６図のとおり
に敷き並べ、敷き並べた底板の縁頂部と溶接す
る。 The bottom plate of the tank is delivered to the site in the form of a coil, and the coil is formed into an L-shape as shown in Figure 5 using a roll forming machine. Next, the molded bottom plates are laid out as shown in Fig. 6 and welded to the edge tops of the laid out bottom plates.

このように、本考案の場合にはＬ型に成型され
た底板の縁頂部（第４図のｂ部）を隅肉溶接する
ため、従来の平板の溶接にくらべ剛性が大きく、
溶接による凹凸の変形がほとんど生じない。その
ため貯蔵時の液深の上下による繰り返し応力を受
ける事がないのでタンクの底板として有利であ
る。又、第４図及び第５図にくめす如く縁頂部の
溶接が長く取れ自動溶接時には有利である。 In this way, in the case of the present invention, the top edge of the L-shaped bottom plate (section b in Figure 4) is fillet welded, so the rigidity is greater than conventional flat plate welding.
Almost no deformation of irregularities occurs due to welding. Therefore, it is advantageous as a bottom plate of a tank because it is not subjected to repeated stress due to the rise and fall of liquid depth during storage. Further, as shown in FIGS. 4 and 5, the welding at the top of the edge can be long, which is advantageous during automatic welding.
