Description

本発明は、端部にベースプレートを備える鉄骨柱を、コンクリート構造物上に設置して、前記鉄骨柱のベースプレートと、前記コンクリート構造物に埋設したアンカー部材の露出部とを連結することによって、前記鉄骨柱を前記コンクリート構造部上に立設させて固定する鉄骨柱の固定方法及び固定構造に関する。   The present invention provides a steel column having a base plate at an end portion on a concrete structure, and connects the base plate of the steel column and an exposed portion of an anchor member embedded in the concrete structure, thereby The present invention relates to a steel column fixing method and a fixing structure in which a steel column is erected and fixed on the concrete structure portion.

従来の技術としては、例えば、図6(a)及び(b)に示されるように、アンカー部材12が、基礎天端面2aにおける鉄骨柱3のベースプレート4の設置予定箇所(当該設置予定箇所には、水平モルタル層15が設けられている)に、その雄ねじ部12aを上方に露出させた状態で設けられている基礎2(コンクリート構造物)において、アンカー部材12の雄ねじ部12aを、鉄骨柱3のベースプレート4のアンカー貫通孔13に挿通させた後、ナット14を雄ねじ部12aに螺合して、鉄骨柱3のベースプレート4を、水平モルタル層15上に締結固定することによって、鉄骨柱3のベースプレート4とアンカー部材12とを連結する構成が知られている(例えば、特許文献1参照)。   As a conventional technique, for example, as shown in FIGS. 6A and 6B, the anchor member 12 is installed at a place where the base plate 4 of the steel pillar 3 is installed on the base top end face 2 a ( In the foundation 2 (concrete structure) provided with the male screw portion 12a exposed upward in the horizontal mortar layer 15), the male screw portion 12a of the anchor member 12 is connected to the steel column 3 The base plate 4 of the steel column 3 is inserted into the anchor through hole 13 of the base plate 4, and the nut 14 is screwed into the male screw portion 12 a, and the base plate 4 of the steel column 3 is fastened and fixed on the horizontal mortar layer 15.

特開2003−184172号公報JP 2003-184172 A

しかしながら、上記従来技術によれば、基礎2を構築する際のコンクリート打設の衝撃によって、アンカー部材12が所定の位置から少しでもずれると、鉄骨柱3のベースプレート4を、コンクリート構造物2上の設置予定箇所に設置したとき、アンカー部材12の雄ねじ部12aを、鉄骨柱3のベースプレート4の貫通孔13に挿通させ難くなり、ベースプレート4とアンカー部材12との連結が困難となる場合がある。
そのため、従来技術においては、コンクリート構造物におけるアンカー部材の高い配置精度が要求されており、施工性を向上させるという点で改善の余地があった。
However, according to the above prior art, when the anchor member 12 is slightly displaced from a predetermined position due to the impact of the concrete placement when the foundation 2 is constructed, the base plate 4 of the steel column 3 is attached to the concrete structure 2.

Therefore, in the prior art, high placement accuracy of the anchor member in the concrete structure is required, and there is room for improvement in terms of improving workability.

本発明は、上記実情に鑑みてなされたものであって、コンクリート打設の衝撃によってアンカー部材が所定の位置より多少ずれた場合であっても、鉄骨柱のベースプレートとアンカー部材とを連結し易く、施工性の良い鉄骨柱の固定方法及び固定構造を提供するものである。   The present invention has been made in view of the above circumstances, and even when the anchor member is slightly deviated from a predetermined position due to the impact of concrete placement, it is easy to connect the base plate of the steel column and the anchor member. The present invention provides a method and structure for fixing a steel column with good workability.
