In the present embodiment, four receiving hardware 6 are provided at 90 ° intervals in consideration of the provision of the movement adjusting means 8, but the number of installations is not limited if not considered. Moreover, although the metal receiver 6 is joined to the outer peripheral surface of the steel pipe 2, it may be joined to the inner peripheral surface. Moreover, you may set suitably the installation height with respect to the steel pipe 2 of the metal receiving object 6. FIG. In the present embodiment, these metal objects 6 are attached to the same height position of the upper end portion of the steel pipe 2.

各受け金物６は、鋼管２に接合されるＬ字型取付ブラケット１１と、Ｌ字型取付ブラケット１１上に設けられる係止部材１２とから構成される。Ｌ字型取付ブラケット１１は、鋼管２に溶接接合等される縦向き片１１ａと、縦向き片１１ａから横方向に折り返されて鋼管２から張り出される横向き片１１ｂとから構成される。また、係止部材１２は、横向き片１１ｂから立設される脚部１２ａと、脚部１２ａ上に形成されたＵ字形状の受け溝部１２ｂとから構成される。受け溝部１２ｂは、上向きに開放されるとともに、その溝方向が鋼管２の径方向に向けて配置される。この受け金物６は、Ｌ字型取付ブラケット１１のみ、あるいは係止部材１２とともに、工場などで鋼管２に一体的に取り付けられる。   Each bracket 6 is composed of an L-shaped mounting bracket 11 joined to the steel pipe 2 and a locking member 12 provided on the L-shaped mounting bracket 11. The L-shaped mounting bracket 11 includes a vertical piece 11 a that is welded to the steel pipe 2 and the like, and a horizontal piece 11 b that is folded back from the vertical piece 11 a in the horizontal direction and projects from the steel pipe 2. Further, the locking member 12 includes a leg portion 12a erected from the lateral piece 11b and a U-shaped receiving groove portion 12b formed on the leg portion 12a. The receiving groove portion 12 b is opened upward, and the groove direction is arranged toward the radial direction of the steel pipe 2. The receiving metal 6 is integrally attached to the steel pipe 2 at the factory or the like together with only the L-shaped mounting bracket 11 or the locking member 12.

鋼柱４には、これを受け金物６を介して既製コンクリート杭部材３に支持させるために、複数の各受け金物６の設置位置に対応させて当該鋼柱４からその径方向外方へ張り出して、複数の鋼製のブラケット７が一体的に接合される。これらブラケット７は、吊り下げられた鋼柱４が鋼管２内に挿入されていく過程で、鋼柱４に溶接接合等された基端とは反対側の先端が受け溝部１２ｂに挿抜自在に挿入される。これにより、受け金物６の受け溝部１２ｂでブラケット７が係止されて既製コンクリート杭部材３に対するその立ち角度がほぼ鉛直に保持されつつ、鋼柱４は、既製コンクリート杭部材３に仮固定される。本実施形態にあってはブラケット７は、鋼柱４の同一高さ位置から、互いに直角に４本設けられている。このブラケット７も、工場などで鋼柱４に一体的に取り付けられる。   In order to receive the steel pillar 4 on the ready-made concrete pile member 3 via the metal fitting 6, the steel pillar 4 protrudes outward in the radial direction from the steel pillar 4 in correspondence with the installation positions of the plurality of metal fittings 6. Thus, the plurality of steel brackets 7 are integrally joined. These brackets 7 are inserted into the receiving groove 12b so that the distal end opposite to the base end welded to the steel column 4 is inserted into the receiving groove 12b in the process of the suspended steel column 4 being inserted into the steel pipe 2. Is done. Thereby, the steel pillar 4 is temporarily fixed to the ready-made concrete pile member 3 while the bracket 7 is latched by the receiving groove part 12b of the receiving metal object 6 and the standing angle with respect to the ready-made concrete pile member 3 is kept substantially vertical. . In the present embodiment, four brackets 7 are provided at right angles to each other from the same height position of the steel column 4. This bracket 7 is also integrally attached to the steel column 4 at a factory or the like.

鋼柱４の位置を調整するためにブラケット７を水平方向および鉛直方向へ移動可能とする位置調整手段８は、９０°間隔で鋼管２に取り付けられた４つの各Ｌ字型取付ブラケット１１の横向き片１１ｂにそれぞれ形成された長穴１３と、各係止部材１２の脚部１２ａに形成され、各長穴１３に長さ方向に沿って移動自在に挿入される図示しないボルト部と、このボルト部を横向き片１１ｂに締着させる図示しないナットとから構成される。ナットによるボルト部の横向き片１１ｂに対する締着位置を調整することによって、ブラケット７を係止する係止部材１２を鉛直方向に移動させることが可能で、これにより鋼柱４の高さ位置が調整されるようになっている。   The position adjusting means 8 that enables the bracket 7 to be moved in the horizontal direction and the vertical direction in order to adjust the position of the steel column 4 is the lateral direction of each of the four L-shaped mounting brackets 11 attached to the steel pipe 2 at intervals of 90 °. A long hole 13 formed in each of the pieces 11b, a bolt portion (not shown) formed in the leg portion 12a of each locking member 12 and movably inserted in each long hole 13 along the length direction, and the bolt It is comprised from the nut which is not shown in figure which fastens a part to the horizontal piece 11b. By adjusting the fastening position of the bolt portion with respect to the laterally facing piece 11b by the nut, it is possible to move the locking member 12 that locks the bracket 7 in the vertical direction, and thereby the height position of the steel column 4 is adjusted. It has come to be.

他方、長穴１３について説明すると、鋼管２の直径方向に位置する一対の受け金物６の長穴１３の長さ方向が、隣接する他の一対の受け金物６の長穴１３の長さ方向と直交し、かつこれら他の一対の受け金物６の受け溝部１２ｂの溝方向と一致するように設定される。従って、鋼管２の直径方向に向かい合ういずれか一対の係止部材１２を長穴１３に沿って同一方向へ移動させると、これら係止部材１２に係止されたブラケット７が移動され、この際、他の一対の係止部材１２に係止されたブラケット７の移動が受け溝部１２ｂ内で許容されて、これにより鋼柱４の水平位置が調整されるようになっている。   On the other hand, when describing the long hole 13, the length direction of the long hole 13 of the pair of receiving hardware 6 positioned in the diameter direction of the steel pipe 2 is the length direction of the long hole 13 of the other adjacent pair of receiving metal objects 6. They are orthogonal to each other and are set so as to coincide with the groove directions of the receiving groove portions 12b of the other pair of receiving objects 6. Therefore, when any one pair of locking members 12 facing the diameter direction of the steel pipe 2 is moved in the same direction along the elongated holes 13, the brackets 7 locked to these locking members 12 are moved. The movement of the bracket 7 locked to the other pair of locking members 12 is allowed in the receiving groove 12b, whereby the horizontal position of the steel column 4 is adjusted.

さらに、ブラケット７位置よりも下方であって、鋼管２内に挿入される鋼柱４の下端部には、周方向に沿って適宜間隔を隔ててかつ同一高さ位置に、複数の支持金物９が一体的に接合される。支持金物９は既製コンクリート杭部材３側の鋼管２に設けるようにしてもよい。これら支持金物９は、鋼柱４から鋼管２へ向かって伸縮自在に設けられる。具体的には支持金物９は、鋼柱４に溶接接合等された筒状の雌ねじ部９ａと、この雌ねじ部９ａに螺合されるロッド状の雄ねじ部９ｂとから構成され、雄ねじ部９ｂを回転させると、鋼柱４と鋼管２との間で伸縮されるようになっている。各支持金物９の雄ねじ部９ｂの伸縮量を調整して鋼管２に当接させることにより、鋼柱４の下端部が鋼管２、ひいては既製コンクリート杭部材３に反力をとって固定され、これにより鋼柱４の倒れ方向への振れ動きが規制され、鋼柱４の仮固定の安定化が確保されるようになっている。   Further, a plurality of support hardwares 9 are provided below the bracket 7 position at the same height position at an appropriate interval along the circumferential direction at the lower end portion of the steel column 4 inserted into the steel pipe 2. Are integrally joined. The support metal 9 may be provided on the steel pipe 2 on the ready-made concrete pile member 3 side. These support hardwares 9 are provided so as to be extendable from the steel pillar 4 toward the steel pipe 2. Specifically, the support metal 9 is composed of a cylindrical female screw portion 9a welded to the steel column 4 and a rod-shaped male screw portion 9b screwed to the female screw portion 9a. When rotated, the steel pillar 4 and the steel pipe 2 are expanded and contracted. By adjusting the amount of expansion and contraction of the male threaded portion 9b of each support metal 9 and bringing it into contact with the steel pipe 2, the lower end of the steel column 4 is fixed to the steel pipe 2 and eventually to the ready-made concrete pile member 3 by fixing the reaction force. Thus, the swinging motion of the steel column 4 in the falling direction is regulated, and the stabilization of the temporary fixing of the steel column 4 is ensured.

次に、本実施形態にかかる鋼柱設置用治具５を用いたコンクリート杭と鋼柱の接合工法を図３に従って説明する。まず、工場等において、接合金物１０を一体的に備えて製造された既製コンクリート杭１の当該接合金物１０に、鋼管２を溶接などにより接合するとともに、鋼管２に、受け金物６のＬ字型取付ブラケット１１を溶接などにより予め一体的に接合する。この際、係止部材１２をＬ字型取付ブラケット１１に取り付けておいてもよい。本実施形態にあっては、係止部材１２は現場で取り付けられるようになっている。鋼管２へのＬ字型取付ブラケット１１の接合作業は、既製コンクリート杭１に鋼管２を接合する前でも、接合した後でもよい。   Next, a method for joining a concrete pile and a steel column using the steel column installation jig 5 according to the present embodiment will be described with reference to FIG.

The mounting bracket 11 is integrally joined beforehand by welding or the like. At this time, the locking member 12 may be attached to the L-shaped mounting bracket 11. In this embodiment, the locking member 12 is attached on site. The joining operation of the L-shaped mounting bracket 11 to the steel pipe 2 may be performed before or after the steel pipe 2 is joined to the ready-made concrete pile 1.

また、工場等において、鋼柱４にブラケット７の基端を溶接などにより予め一体的に接合する。さらに必要に応じて、鋼柱４に支持金物９の雌ねじ部９ａを溶接などにより予め一体的に接合する。これら接合作業を工場など設備の整った場所で行えば、受け金物６付きの既製コンクリート杭部材３およびブラケット７付きの鋼柱４を高い精度で高品質に製造することができる。   In addition, in a factory or the like, the base end of the bracket 7 is integrally joined to the steel column 4 in advance by welding or the like. Further, if necessary, the internal thread portion 9a of the support metal 9 is integrally joined to the steel column 4 in advance by welding or the like. If these joining operations are performed in a well-equipped place such as a factory, the ready-made concrete pile member 3 with the metal fitting 6 and the steel column 4 with the bracket 7 can be manufactured with high accuracy and high quality.

次いで、これら既製コンクリート杭部材３および鋼柱４を工場等から現場に搬入し、既製コンクリート杭部材３を、プレボーリング工法や中堀工法などの周知の埋め込み杭工法によって地盤面Ｇ付近に打設して埋設する。そして既製コンクリート杭部材３内方に、セメントミルクＣ１を充填し固化させる（図３（ａ）参照）。次いで、鋼管２内に滞留する土や杭周固定液の固化物などを除去し、セメントミルクＣ１頂面にコンクリート止め１４を、必要に応じてセットするとともに、鋼管２内面を洗浄する（図３（ｂ）参照）。   Next, these ready-made concrete pile members 3 and steel pillars 4 are brought into the field from a factory or the like, and the ready-made concrete pile members 3 are placed near the ground surface G by a well-known embedded pile method such as a pre-boring method or a Nakabori method. Buried. Then, cement milk C1 is filled inside the ready-made concrete pile member 3 and solidified (see FIG. 3A). Subsequently, the soil staying in the steel pipe 2 and solidified solids of the pile periphery fixing liquid are removed, and a concrete stopper 14 is set on the top surface of the cement milk C1 as necessary, and the inner surface of the steel pipe 2 is washed (FIG. 3). (See (b)).

次いで、揚重機等を用いて鋼柱４を既製コンクリート杭部材３上に吊り込む。この際、事前に係止部材１２をＬ字型取付ブラケット１１に取り付けておく。図示例にあっては、鋼柱４の上端に柱継ぎ手１５が設けられている。吊り込まれた鋼柱４は、順次下降され、鋼柱４の下端部が鋼管２内に挿入されつつ、ブラケット７先端が受け金物６の受け溝部１２ｂに挿入されて係止され、これにより鋼柱４は立ち角度を保って受け金物６に保持される。この際、必要に応じて、位置調整手段８により、ブラケット７を水平方向や鉛直方向へ移動させて鋼柱４の位置を微調整する。微調整が完了したら、ナットで係止部材１２の脚部１２ａをＬ字型取付ブラケット１１の横向き片１１ｂに締着させる。   Next, the steel pillar 4 is suspended on the ready-made concrete pile member 3 using a lifting machine or the like. At this time, the locking member 12 is attached to the L-shaped mounting bracket 11 in advance. In the illustrated example, a column joint 15 is provided at the upper end of the steel column 4. The suspended steel column 4 is sequentially lowered, and the lower end portion of the steel column 4 is inserted into the steel pipe 2 while the tip of the bracket 7 is inserted into the receiving groove portion 12b of the receiving hardware 6 and locked. The column 4 is held by the receiving metal 6 while maintaining a standing angle. At this time, the position adjusting means 8 finely adjusts the position of the steel column 4 by moving the bracket 7 in the horizontal direction or the vertical direction as necessary. When the fine adjustment is completed, the leg portion 12a of the locking member 12 is fastened to the laterally facing piece 11b of the L-shaped mounting bracket 11 with a nut.

その後、鋼柱４の各支持金物９をその雄ねじ部９ｂの伸張量を調節して鋼管２に当接させ、これにより鋼柱４が倒れ方向に振れ動くことを既製コンクリート杭部材３に反力をとって規制する。以上の作業は鋼柱４を揚重機等で吊り下げた状態で行われる。ブラケット７を受け金物６に係止させることで鋼柱４の既製コンクリート杭部材３に対する仮固定が完了したならば、揚重機等による鋼柱４の吊り下げ作業は終了し、鋼柱４は既製コンクリート杭部材３によって支持される（図３（ｃ）参照）。   After that, each supporting metal 9 of the steel pillar 4 is brought into contact with the steel pipe 2 by adjusting the extension amount of the male threaded portion 9b, whereby the steel pillar 4 swings in the falling direction and reacts against the ready-made concrete pile member 3. To regulate. The above operation is performed in a state where the steel column 4 is suspended by a lifting machine or the like. When the temporary fixing of the steel column 4 to the ready-made concrete pile member 3 is completed by locking the bracket 7 to the hardware 6, the suspension work of the steel column 4 by a lifting machine or the like is finished, and the steel column 4 is ready-made. It is supported by the concrete pile member 3 (see FIG. 3C).

次いで、円筒状の鋼柱４内方を通して、コンクリート止め１４上方にコンクリートＣ２を充填する。この際、支持金物９は、充填コンクリートＣ２内に埋設される。鋼柱４内に充填コンクリートＣ２がある程度進入してきたならば、鋼柱４内方を通してのコンクリートＣ２の充填作業を中止し、その後は、鋼柱４と鋼管２との間の隙間から既製コンクリート杭部材３内にコンクリートＣ２を充填する（図３（ｄ）参照）。最終的には、鋼管２天端から鋼柱４内にわたって予め設定された深さｈとなるように、鋼柱４内へのコンクリートＣ２の充填量が管理される。そして、既製コンクリート杭部材３内に充填したコンクリートＣ２が固化したならば、鋼柱４上に、柱継ぎ手１５を介して上方の鋼柱４を接合する（図３（ｅ）参照）。その後、図１に示すように、受け金物６およびブラケット７を埋設するように、土間コンクリートＣ３を打設する。これにより既製コンクリート杭部材３と鋼柱４との接合が完了する。   Next, the concrete C2 is filled above the concrete stopper 14 through the inside of the cylindrical steel column 4. At this time, the support metal 9 is embedded in the filled concrete C2. If the filled concrete C2 enters the steel column 4 to some extent, the filling operation of the concrete C2 through the inside of the steel column 4 is stopped, and thereafter, the ready-made concrete pile is inserted from the gap between the steel column 4 and the steel pipe 2. Concrete C2 is filled into the member 3 (see FIG. 3D). Finally, the filling amount of the concrete C2 into the steel column 4 is managed so that the depth h is set in advance from the top end of the steel pipe 2 to the inside of the steel column 4. And if the concrete C2 filled in the ready-made concrete pile member 3 solidifies, the upper steel pillar 4 will be joined on the steel pillar 4 via the pillar joint 15 (refer FIG.3 (e)). Thereafter, as shown in FIG. 1, the soil concrete C3 is placed so as to embed the metal receiving piece 6 and the bracket 7. Thereby, joining with the ready-made concrete pile member 3 and the steel pillar 4 is completed.

このようにして施工された既製コンクリート杭部材３と鋼柱４との接合構造にあっては、受け金物６にブラケット７を係止して既製コンクリート杭部材３に鋼柱４を仮固定した状態で、既製コンクリート杭部材３内から土間にわたって打設したコンクリートＣ３に、受け金物６およびブラケット７が埋設されることになる。図４に示すように、例えば受け金物６やブラケット７を撤去してしまった場合に比べて、これら受け金物６やブラケット７をコンクリートＣ３に埋設することにより、既製コンクリート杭部材３と鋼柱４の構造的連続性や接合剛性の向上に寄与させることができる。接合剛性が弱い場合には、この部分でピン接合Ｘとなり、鋼柱４が負担すべき曲げ応力Ｍが大きくなる（図４（ａ）参照）。これに比べて、受け金物６やブラケット７をコンクリートＣ３に埋設することにより接合剛性が向上すると、反曲点Ｙを上方に上げることになり、鋼柱４が負担すべき曲げ応力Ｍを低減することができ（図４（ｂ）参照）、鋼柱４のサイズダウンを達成することが可能となり、構造力学的性能を向上させることができる。   In the joint structure of the ready-made concrete pile member 3 and the steel column 4 thus constructed, the steel column 4 is temporarily fixed to the ready-made concrete pile member 3 by locking the bracket 7 to the metal fitting 6. Thus, the receiving metal 6 and the bracket 7 are buried in the concrete C3 that is placed from the ready-made concrete pile member 3 to the soil. As shown in FIG. 4, for example, compared with the case where the metal fitting 6 and the bracket 7 are removed, by embedding the metal fitting 6 and the bracket 7 in the concrete C3, the ready-made concrete pile member 3 and the steel column 4 are embedded. It is possible to contribute to the improvement of the structural continuity and bonding rigidity. In the case where the joining rigidity is weak, this portion becomes the pin joint X, and the bending stress M to be borne by the steel column 4 becomes large (see FIG. 4A). Compared to this, when the joint rigidity is improved by embedding the metal fitting 6 and the bracket 7 in the concrete C3, the inflection point Y is raised upward, and the bending stress M to be borne by the steel column 4 is reduced. (See FIG. 4B), it is possible to reduce the size of the steel column 4, and to improve the structural mechanical performance.

以上説明した本実施形態にあっては、既製コンクリート杭部材３の鋼管２に接合した受け金物６の受け溝部１２ｂに鋼柱４のブラケット７を係止させるだけで鋼柱４を既製コンクリート杭部材３に支持させて仮固定することができ、仮固定のための構造がきわめて簡単であるとともに、取り扱い性よく施工することができる。これにより、鋼柱４の既製コンクリート杭部材３に対する接合作業の施工性を向上することができる。また、受け金物６およびブラケット７を既製コンクリート杭部材３や鋼柱４に予め一体的に接合するようにしていて、この接合作業は工場等で行うことが可能であり、高品質の鋼柱設置用治具５を構成することができるとともに、高精度で接合された受け金物６およびブラケット７により現場施工性を向上できる。   In the present embodiment described above, the steel pillar 4 is made of the ready-made concrete pile member only by locking the bracket 7 of the steel pillar 4 to the receiving groove 12b of the metal fitting 6 joined to the steel pipe 2 of the ready-made concrete pile member 3. 3 and can be temporarily fixed, the structure for temporary fixing is very simple, and construction can be performed with good handling. Thereby, the workability of the joining operation | work with respect to the ready-made concrete pile member 3 of the steel pillar 4 can be improved. In addition, the bracket 6 and the bracket 7 are integrally joined to the ready-made concrete pile member 3 and the steel pillar 4 in advance, and this joining work can be performed in a factory or the like, and a high-quality steel pillar is installed. The work jig 5 can be configured, and on-site workability can be improved by the metal fitting 6 and the bracket 7 joined with high accuracy.

さらに、これら受け金物６やブラケット７を単にコンクリートＣ３中に埋設するだけで、構造強度を高く確保することができる。また、コンクリートＣ２中に埋設した支持金物９により、さらに強度を補うことができる。また、位置調整手段８による鉛直方向および水平方向への位置調整で、鋼柱４を既製コンクリート杭部材３に対して精度よく仮固定することができる。さらに、支持金物９で既製コンクリート杭部材３に対し鋼柱４を適切に支持することができ、鋼柱４の振れ動きを規制して仮固定の安定性を向上することができる。   Furthermore, high structural strength can be ensured simply by embedding these metal fittings 6 and brackets 7 in the concrete C3. Further, the strength can be further supplemented by the support metal 9 embedded in the concrete C2. Moreover, the steel column 4 can be temporarily fixed with respect to the ready-made concrete pile member 3 by the position adjustment to the vertical direction and horizontal direction by the position adjustment means 8 with high precision. Furthermore, the steel pillar 4 can be appropriately supported with respect to the ready-made concrete pile member 3 by the support hardware 9, and the swinging movement of the steel pillar 4 can be regulated to improve the stability of temporary fixing.
