Description

この発明は、Ｈ型鉄骨のウェブの両側面に添わせる一対の矩形のスプライス板を、上部フランジの下部に横長に配置して仮止めする作業用の治具に関する。   The present invention relates to a working jig for temporarily fixing a pair of rectangular splice plates attached to both side surfaces of an H-shaped steel frame web in a horizontally long manner at the lower portion of an upper flange.

Ｈ型鉄骨の端部同士をボルト接合する場合、両鉄骨のウェブ間を接続するために、矩形の一対のスプライス板が、ウェブの両側面に添わされる。スプライス板とウェブのボルト締め作業は、建設現場において行われるが、鉄骨には予め加工場においてスプライス板が仮止めされ、建設現場に搬入される。
加工場におけるＨ型鉄骨に対するウェブ接続用スプライス板の仮止め作業は以下のように行われる。まず、フランジを水平に配置して置かれたＨ型鉄骨のウェブの両側面に、短冊形鉄板からなるの２枚のスプライス板を添わせ、その上隅部のボルト挿通孔にボルトを挿通してスプライス板を自由に枢止する。この自由枢止状態においては、スプライス板の上部短辺がウェブの端縁から斜め下方へ突出し、スプライス板が縦長にやや傾いた状態で吊り下げられる形となる。その後、当該スプライス板を上方回転させることにより、上部フランジの下面に沿って横長に配置した位置で前記ボルトにて仮止めする。なお、出願人において、上記のようなウェブ接続用スプライス板の仮止め技術に関する先行技術文献は見出せなかった。 When bolting the ends of H-shaped steel frames, a pair of rectangular splice plates are attached to both sides of the web in order to connect the webs of both steel frames. The bolting operation of the splice plate and the web is performed at the construction site, but the splice plate is temporarily fixed to the steel frame in advance at the processing site and is carried into the construction site.
The temporary fixing operation of the splice plate for web connection to the H-shaped steel frame at the processing site is performed as follows. First, two splice plates made of strip-shaped iron plates are attached to both sides of an H-shaped steel web placed with the flanges placed horizontally, and bolts are inserted into the bolt insertion holes in the upper corners. To freely pivot the splice plate. In the free pivoting state, the upper short side of the splice plate protrudes obliquely downward from the edge of the web, and the splice plate is suspended in a vertically inclined state. Thereafter, the splice plate is rotated upward to temporarily fix the splice plate with the bolt at a position arranged horizontally along the lower surface of the upper flange. The applicant could not find any prior art documents related to the temporary fixing technology of the splice plate for web connection as described above.

しかしながら、大型の鉄骨を取り扱う鉄骨加工現場にあって、一人で上記スプライス板の装着、固定作業を行うのは極めて作業効率が悪く、作業者にとって重労働となるという問題点がある。
したがって、この発明は、Ｈ型鉄骨のウェブの両側面に添わせる一対の矩形のスプライス板を、上部フランジの下部に横長に配置して仮止めする作業を作業者に対する比較的小さい負担で、効率よく、簡単に行うことができる小型軽量な、治具を提供することを課題としている。 However, in a steel processing site where large steel frames are handled, there is a problem that it is extremely inefficient to perform the work of attaching and fixing the splice plate alone, and it becomes a heavy labor for the operator.
Therefore, according to the present invention, a pair of rectangular splice plates to be attached to both sides of the H-shaped steel web are placed horizontally in the lower part of the upper flange and temporarily fixed with a relatively small burden on the operator. It is an object to provide a small and light jig that can be easily and easily performed.

上記課題を解決するため、この出願の発明においては、ボルトＢの頭部に嵌合する係合部２と、この係合部２から、ウェブ２３上に自由枢止状態にあるスプライス板２４の板面に沿って伸びる第１の杆部３と、第１の杆部３の端からスプライス板２４側へ直角に伸び、スプライス板２４の上部短辺２４ｃに当接可能に配置される押圧部４と、押圧部４から第１の杆部３と反対方向へ伸びる第２の杆部５とを具備させて、Ｈ型鉄骨２１のウェブ２３にスプライス板２４を装着、仮止めする治具１を構成する。押圧部４をスプライス板２４の上部短辺２４ｃに当接させた状態で、第２の杆部５の端部を下方へ押し回すことにより、スプライス板２４を上方回転させ、仮止め位置に配置した状態で、ボルトＢにナットを螺合して仮締め作業を可能とする。   In order to solve the above-mentioned problem, in the invention of this application, the engagement portion 2 fitted to the head of the bolt B, and the splice plate 24 in a free pivot state on the web 23 from the engagement portion 2. A first flange portion 3 extending along the plate surface, and a pressing portion that extends perpendicularly from the end of the first flange portion 3 toward the splice plate 24 and is disposed so as to be able to contact the upper short side 24c of the splice plate 24 4 and a second flange 5 extending from the pressing portion 4 in the opposite direction to the first flange 3, and a jig 1 for attaching and temporarily fixing the splice plate 24 to the web 23 of the H-shaped steel frame 21. Configure. In a state where the pressing portion 4 is in contact with the upper short side 24c of the splice plate 24, the end portion of the second flange portion 5 is pushed downward to rotate the splice plate 24 upward, and is disposed at the temporary fixing position. In this state, a nut is screwed onto the bolt B to allow a temporary fastening operation.

フランジ２２を水平に配置して置かれたＨ型鉄骨２１のウェブ２３に、縦長矩形の２枚のスプライス板２４を、その上隅部に挿通されたボルトＢにて枢止することにより、上部短辺２４ｃをウェブ２３の端縁から斜め下方へ突出させた自由枢止状態に接続した後、この出願の発明に係る仮止め用治具１を用いて、スプライス板２４を上方回転させ、上部フランジ２２の下面に沿って横長に配置する。この状態で、ボルトＢにナットを締め付けてスプライス板を仮止めする。仮止め用治具１を用いれば、作業者に対する比較的小さい負担で、効率よく、簡単に仮止め作業を行うことができるという効果を有する。   The web 23 of the H-shaped steel frame 21 in which the flange 22 is placed horizontally is pivoted with two vertically long rectangular splice plates 24 with bolts B inserted through the upper corners thereof. After connecting the short side 24c to the free pivoting state in which the short side 24c protrudes obliquely downward from the edge of the web 23, the splice plate 24 is rotated upward using the temporary fixing jig 1 according to the invention of this application, It is arranged horizontally along the lower surface of the flange 22. In this state, a nut is fastened to the bolt B to temporarily fix the splice plate. If the temporary fixing jig 1 is used, the temporary fixing operation can be performed efficiently and easily with a relatively small burden on the operator.
