The steel floating roof type tank 1 is composed of a bottom plate 2, a side plate 3, a floating roof 5, a sealing device 8, and the like. In the case of the floating roof 5 having a single deck structure, a deck plate 6 of a thin steel plate, It is composed of a steel plate annular box pontoon 7 surrounding the outer periphery of the deck plate 6.
The pontoon 7 of the floating roof 5 is welded and erected on the inner peripheral edge of the pontoon bottom plate 7d in the vicinity of the joint portion between the annular outer rim plate 7a welded to the outer peripheral edge of the pontoon bottom plate 7d and the deck plate 6. An annular space formed by the annular inner rim plate 7b is erected at predetermined intervals with both ends of the plurality of bulkhead plates 7c abutting against the outer rim plate 7a and the inner rim plate 7b, respectively, and welded. After being fixed and partitioned, the top plate 7e passed from the outer rim plate 7a to the inner rim plate 7b is welded and fixed to form a plurality of box-shaped independent spaces. .

パネルや鋼板等の平板相互をT字型に当接する構造を有する鋼構造物の構築において、底板上で一方の平板(以下、立設板)と当接して直交する他方の平板(以下、直交立設板)とをT字型に組立て立設する作業は、重い当該立設板または直交立設材を転倒しないように支えながら組立てるので、人手を要するだけでなく、不安全であった。
例えば、浮屋根式タンク1の浮屋根5のポンツーン7を組立てる際には、前記直交立設板に相当するバルクヘッド7cを前記立設材に相当する外リム板7a又は内リム板7b鋼板に当接して立設する作業は、作業員が重いバルクヘッド7cが転倒しないよう支えながら行う力仕事であるうえ、取付位置や垂直度を調整しながら、仮付溶接して組立てる必要があり、人手を要するため、作業効率を上げるうえで課題となっていた。
また、大型のバルクヘッド7cを人力で支える作業は不安定かつ不安全であり、所定位置に適切に組立てるためには技量や時間を要していたばかりでなく、そのような大型のバルクヘッド7cを従来の重い治工具を使用して組立てる場合には、繁雑な作業を要していた。
In the construction of a steel structure having a structure in which flat plates such as panels and steel plates are in contact with each other in a T shape, the other flat plate (hereinafter referred to as orthogonal) is in contact with and orthogonal to one flat plate (hereinafter referred to as standing plate) on the bottom plate. The operation of assembling and erecting a standing plate) in a T-shape is not only safe, but also unsafe because it assembles while supporting the heavy standing plate or the orthogonal standing material so as not to fall.
For example, when the pontoon 7 of the floating roof 5 of the floating roof type tank 1 is assembled, the bulkhead 7c corresponding to the orthogonal standing plate is used as the outer rim plate 7a or the inner rim plate 7b steel plate corresponding to the standing member. The work of standing and abutting is a laborious work performed by an operator while supporting the heavy bulkhead 7c not to fall down, and it is necessary to assemble it by temporary welding while adjusting the mounting position and verticality. Therefore, it has been a problem in improving work efficiency.
In addition, the work of manually supporting the large bulkhead 7c is unstable and unsafe, and not only requires skill and time to properly assemble the large bulkhead 7c. When assembling using the conventional heavy jigs and tools, complicated work was required.

It does not relate to an assembly jig that is fixed to a panel material or a steel plate, etc., and does not relate to an assembly jig that supports a large panel material or a steel plate so as not to fall.

特許文献2「溶接継手の変形抑制部材とこの変形抑制部材を用いた変形抑制方法」は、鋼板組立時に使用する下向きコの字状の門形部材と楔状部材等で構成された溶接継手の変形抑制部材に関するものであるが、立設した鋼板が転倒しないように支持する部材に関するものではない。   Patent Document 2 “deformation restraining member of welded joint and deformation restraining method using this deformation restraining member” describes the deformation of a welded joint composed of a downward U-shaped gate-shaped member and a wedge-shaped member used at the time of assembling a steel plate. Although it is related to the suppressing member, it is not related to a member that supports the standing steel plate so as not to fall.

特許文献3「金属部材の結合方法および位置決め治具」は、挿通孔を有するメス部材と、該挿通孔に挿通されて摺動自在な軸部を有するオス部材とから構成される溶接前の金属部材の位置決め治具に関するものであり、くさび状の角矢やボルト等で鋼板に固定する組立治具に関するものではなく、立設した鋼板が転倒しないように支持する治具に関するものでもない。 Patent Document 3 “Metal Member Coupling Method and Positioning Jig” is a pre-weld metal composed of a female member having an insertion hole and a male member having a slidable shaft portion inserted through the insertion hole. The present invention relates to a member positioning jig, and does not relate to an assembly jig that is fixed to a steel plate with a wedge-shaped square arrow, bolt, or the like, nor is it related to a jig that supports a standing steel plate so as not to fall.
