Description

本発明は、建入れ調整装置に関する。詳しくは、鋼管で囲まれた鉄骨柱の建入れを調整する建入れ調整装置に関する。   The present invention relates to a building adjustment apparatus. Specifically, the present invention relates to an erection adjustment device that adjusts the erection of a steel column surrounded by a steel pipe.

従来より、杭頭部に鋼管が嵌め込んで杭を打設し、この杭上に鉄骨柱の建方を行う場合がある。このような鉄骨の建方では、鉄骨柱の精度誤差を所定の範囲内に収めるために、建入れを調整する。   Conventionally, a steel pipe is fitted into a pile head and a pile is driven, and a steel column is erected on the pile. In such a steel frame construction, the construction is adjusted in order to keep the accuracy error of the steel column within a predetermined range.

具体的には、建入れ調整の対象となる鉄骨柱の柱頭部とこの鉄骨柱の周囲の柱の柱脚部との間にワイヤーを架け渡し、このワイヤーの途中にターンバックルまたはレバーブロックを取り付ける。そして、ターンバックルまたはレバーブロックを調整して、対象となる鉄骨柱の柱頭部から周囲の柱の柱脚部までの距離を調節することで、この対象となる鉄骨柱の建入れを調整する。   Specifically, a wire is bridged between the column head of the steel column that is the subject of building adjustment and the column base of the column around this steel column, and a turnbuckle or lever block is attached in the middle of this wire . The turnbuckle or lever block is adjusted to adjust the distance from the column head of the target steel column to the column base of the surrounding column, thereby adjusting the construction of the target steel column.

しかしながら、この手法では、ワイヤーを周囲の鉄骨柱の柱脚部に向かって架け渡すことになる。したがって、例えば駅のホーム上に鉄骨柱の建方を行う場合、駅の使用を継続しながら鉄骨建方を行うため、ワイヤーを架け渡すことができない、という問題があった。   However, in this method, the wire is bridged toward the column base of the surrounding steel column. Therefore, for example, when constructing a steel column on the platform of a station, there is a problem that the wire cannot be bridged because the steel frame is constructed while continuing to use the station.

そこで、例えば、鉄骨柱の柱脚部にエレクションピースを取り付けておき、上下のエレクションピースの間に歪み直し装置を設ける方法が提案されている（特許文献１、２参照）。
この提案によれば、鉄骨柱間にワイヤーを架け渡す必要がないため、駅の使用を継続しながら鉄骨建方を行うことができる。 In view of this, for example, a method has been proposed in which an erection piece is attached to a column base of a steel column and a distortion correcting device is provided between the upper and lower erection pieces (see Patent Documents 1 and 2).
According to this proposal, since it is not necessary to bridge the wire between the steel columns, the steel frame can be constructed while continuing to use the station.

しかしながら、上述の方法では、鉄骨柱にエレクションピースを溶接し、建入れの調整後にエレクションピースを撤去するため、手間がかかってしまい、施工コストが上昇する、という問題があった。また、エレクションピースの溶接により鉄骨柱の母材を傷めるおそれがあった。   However, the above-described method has a problem in that the erection piece is welded to the steel column and the erection piece is removed after adjustment of erection, which takes time and increases the construction cost. Moreover, there was a possibility that the base material of the steel column was damaged by welding of the erection piece.

本発明は、施工コストを低減しつつ、母材を極力傷めずに鉄骨柱の建入れを調整できる建入れ調整装置を提供することを目的とする。   An object of the present invention is to provide an erection adjustment device capable of adjusting the erection of a steel column without damaging the base material as much as possible while reducing the construction cost.

請求項１に記載の建入れ調整装置は、鋼管で囲まれた鉄骨柱の建入れを調整する建入れ調整装置であって、前記鋼管と前記鉄骨柱の側面との間に設けられた油圧ジャッキおよびサポートジャッキを備え、当該油圧ジャッキは、前記鋼管に反力をとって前記鉄骨柱の側面を押圧して、前記鋼管と前記鉄骨柱との間隔を調整することで、前記鉄骨柱の建入れを調整可能であり、前記サポートジャッキは、ロックナットを締め付けることにより、前記鋼管に反力をとって前記鉄骨柱の側面を支持して、前記鉄骨柱の建入れを保持することを特徴とする。 The erection adjustment device according to claim 1 is an erection adjustment device that adjusts the erection of a steel column surrounded by a steel pipe, and is a hydraulic jack provided between the steel pipe and a side surface of the steel column. And the support jack, the hydraulic jack takes a reaction force against the steel pipe, presses the side surface of the steel column, and adjusts the distance between the steel pipe and the steel column, thereby erection of the steel column The support jack supports the side surface of the steel column by holding a reaction force against the steel pipe by tightening a lock nut, and holds the steel column erection. .

この発明によれば、押圧機構により鉄骨柱の側面を押圧することで、鉄骨柱から周囲の鋼管までの距離を調節して、鉄骨柱の建入れを調整する。
よって、鉄骨柱間にワイヤーを架け渡す必要がないため、既存構造物の使用を継続しながら鉄骨建方を行うことができる。また、鉄骨柱に部材を溶接しないため、母材を極力傷めずに施工コストを低減できる。 According to this invention, the distance from the steel column to the surrounding steel pipe is adjusted by pressing the side surface of the steel column by the pressing mechanism, thereby adjusting the erection of the steel column.
Therefore, since it is not necessary to bridge the wire between the steel columns, the steel frame can be constructed while continuing to use the existing structure. Moreover, since the member is not welded to the steel column, the construction cost can be reduced without damaging the base material as much as possible.

本発明の建入れ調整装置は、前記鋼管に反力をとって前記鉄骨柱の側面を支持する支持機構をさらに備えることが好ましい。 It is preferable that the erection adjustment device of the present invention further includes a support mechanism that supports a side surface of the steel column by applying a reaction force to the steel pipe .

この発明によれば、押圧機構により鉄骨柱の建入れを調整した後、支持機構により鉄骨柱の側面を支持することで、鉄骨柱の建入れを保持できる。   According to this invention, after adjusting the erection of the steel column by the pressing mechanism, the erection of the steel column can be held by supporting the side surface of the steel column by the support mechanism.

本発明によれば、押圧機構により鉄骨柱の側面を押圧することで、鉄骨柱から周囲の鋼管までの距離を調節して、鉄骨柱の建入れを調整する。よって、鉄骨柱間にワイヤーを架け渡す必要がないため、既存構造物の使用を継続しながら鉄骨建方を行うことができる。また、鉄骨柱に部材を溶接しないため、母材を極力傷めずに施工コストを低減できる。   According to the present invention, by pressing the side surface of the steel column by the pressing mechanism, the distance from the steel column to the surrounding steel pipe is adjusted to adjust the installation of the steel column. Therefore, since it is not necessary to bridge the wire between the steel columns, the steel frame can be constructed while continuing to use the existing structure. Moreover, since the member is not welded to the steel column, the construction cost can be reduced without damaging the base material as much as possible.

次に、鉄骨梁４を設置し、その後、再度建入れの調整を行う。その後、押圧機構７０を受けプレート４０から取り外す。
次に、アンカーボルト１３を本締めして、鉄骨柱３のベースプレートと杭２の杭頭との隙間に無収縮モルタルを充填する。
この無収縮モルタルが硬化した後、建入れ調整装置３０を取り外す。 Next, the steel beam 4 is installed, and then the erection is adjusted again. Thereafter, the pressing mechanism 70 is removed from the receiving plate 40.
Next, the anchor bolt 13 is finally tightened, and the non-shrinking mortar is filled in the gap between the base plate of the steel column 3 and the pile head of the pile 2.
