前記従来の圧入装置の場合は、液圧ジャッキにより移動される移動部材とチャ ックベースとは、それらに設けられた凹球状支承面と凸球状支承面とにより相対 的に摺動自在に接合されているので、凹球状支承面と凸球状支承面とを、高精度 で切削加工することは困難であり、前記チャックベースには、ロッド嵌合用溝を 有する複数の係止片が、係止位置および開放位置に回動し得るように横軸により 枢着され、各係止片には、これを係止位置に向かって回動するように働く付勢部 材が係合されて、自動チャック装置が構成されているので、前記付勢部材の力が 強過ぎると、移動部材または支持部材に対し相対的に上昇移動する移送用ロッド の係合用膨出部に係止片が係合した状態で、自動チャック装置全体が持上げられ ていくので、このようなことがないように、付勢部材の力を小さくする必要があ り、そのため付勢部材の強さの設定が煩雑である。 In the case of the conventional press-fitting device, the moving member moved by the hydraulic jack and the chuck base are relatively slidably joined by the concave spherical bearing surface and the convex spherical bearing surface provided on them. Therefore, it is difficult to machine the concave spherical bearing surface and the convex spherical bearing surface with high accuracy.Therefore, the chuck base is provided with a plurality of locking pieces having rod fitting grooves. The automatic chucking device is pivotally mounted by a horizontal shaft so that it can be rotated to the open position, and each locking piece is engaged with a biasing member that works to rotate the locking piece toward the locking position. If the force of the urging member is too strong, the locking piece is engaged with the engaging bulge of the transfer rod that moves upward relative to the moving member or the supporting member. , The entire automatic chucking device will be lifted. As there is no such thing as, must reduce the force of the biasing member, is complicated intensity settings Therefore biasing member.

図面は、本考案の実施例を示すものであって、ケーソンからなる被圧入構造物 １の上部に複数の支持部材２が載置され、その支持部材２の上部にセンターホー ルジャッキからなる液圧ジャッキ３のシリンダ１７が載置され、前記液圧ジャッ キ３のピストン１８に、移動部材４を介して上部グリッパー６が載置されて固定 され、前記支持部材２内に下部グリッパー５が配置されている。 The drawings show an embodiment of the present invention, in which a plurality of supporting members 2 are placed on an upper portion of a press-fitted structure 1 made of a caisson, and a hydraulic pressure consisting of a center hole jack is placed on the upper portion of the supporting member 2. The cylinder 17 of the jack 3 is mounted, the upper gripper 6 is mounted and fixed to the piston 18 of the hydraulic jack 3 via the moving member 4, and the lower gripper 5 is arranged in the support member 2. ing.
【０００６】 前記下部グリッパー５および上部グリッパー６の構成について説明すると、下 側に向かって縮小する台形凹面７を有する円環状のグリッパーベース８における 前記台形凹面７に、下側に向かって縮小する台形外面９を有する複数（例えば４ 箇）のグリッパー１０における前記台形外面９が摺動自在に載置されている。The structure of the lower gripper 5 and the upper gripper 6 will be described. The trapezoidal concave surface 7 of the annular gripper base 8 having the trapezoidal concave surface 7 that shrinks downward is trapezoidal that shrinks downward. The trapezoidal outer surfaces 9 of a plurality (for example, four) of grippers 10 having outer surfaces 9 are slidably mounted.
【０００７】 隣り合うグリッパー１０の側部に設けられたばね嵌入孔１９に、拡開用ばね１ １の端部が嵌入され、前記グリッパーベース８の上端部に係合されると共に、各 グリッパー１０の上端部に対向する押下用係合部材１３の周囲に複数の上部ブラ ケット２０が固定され、前記グリッパーベース８の周囲に、各上部ブラケット２ ０の下部において下部ブラケット２１が固定され、前記上部ブラケット２０と下 部ブラケット２１とは押下用ばね１２を介して連結されている。An end portion of the expanding spring 11 is fitted into a spring fitting hole 19 provided at a side portion of the adjacent grippers 10, and is engaged with an upper end portion of the gripper base 8, and at the same time, each gripper 10 is A plurality of upper brackets 20 are fixed around the pressing engagement member 13 facing the upper end, and lower brackets 21 are fixed around the gripper base 8 at the lower part of each upper bracket 20. 20 and the lower bracket 21 are connected via a pressing spring 12.
【０００８】 断面円形の鋼製圧入用ロッド１６は、その長手方向に一定間隔で一体に設けら れた多数の係合用膨出部１４と、各係合用膨出部１４の上部に連設された台形外 面１５と、台形外面１５の上端部に連設された小径軸部２３とを備え、前記圧入 用ロッド１６は、支持部材２と液圧ジャッキ３と移動部材４と下部グリッパー５ および上部グリッパー６とに挿通され、前記圧入用ロッド１６の下部は、地盤に 埋設されると共に、圧入用ロッド１６の下端部にアンカー部材（図示を省略した ）が取付けられている。The steel press-fitting rod 16 having a circular cross section is provided continuously with a large number of engaging bulging portions 14 integrally provided at regular intervals in the longitudinal direction and the upper portions of the engaging bulging portions 14. A trapezoidal outer surface 15 and a small-diameter shaft portion 23 connected to the upper end of the trapezoidal outer surface 15, and the press-fitting rod 16 includes a support member 2, a hydraulic jack 3, a moving member 4, a lower gripper 5, and The lower part of the press-fitting rod 16 is inserted into the upper gripper 6 and is embedded in the ground, and an anchor member (not shown) is attached to the lower end of the press-fitting rod 16.
【０００９】 ケーソン等の被圧入構造物１を地盤に向かって鉛直方向に圧入する場合は、液 圧ジャッキ３を伸長させると、上部グリッパー６における各グリッパー１０は、 圧入用ロッド１６の係合用膨出部１４の下部に係合して、圧入用ロッド１６を押 上げようとするが、圧入用ロッド１６の下部が地盤に固定されていて、その圧入 用ロッド１６を押上げることができないので、被圧入構造物１が地盤に圧入され ていく。When the press-fitted structure 1 such as a caisson is press-fitted vertically toward the ground, when the hydraulic jack 3 is extended, each gripper 10 in the upper gripper 6 expands for engaging the press-fitting rod 16. It tries to push up the press-fitting rod 16 by engaging with the lower part of the outlet portion 14, but since the lower part of the press-fitting rod 16 is fixed to the ground, the press-fitting rod 16 cannot be pushed up. The press-fitted structure 1 is pressed into the ground.
【００１０】 また下部グリッパー５における各グリッパー１０は、圧入用ロッド１６におけ る台形外面１５および係合用膨出部１４により外向きに移動され、その係合用膨 出部１４を通過すると、押下用係合部材１３により押下げられて、係合用膨出部 １４の下面に対向する。このようにして、１サイクルを終了するので、液圧ジャ ッキ３の伸縮動作を反復して行なうことにより、被圧入構造物１を地盤に圧入し ていくことができる。Further, each gripper 10 in the lower gripper 5 is moved outward by the trapezoidal outer surface 15 of the press-fitting rod 16 and the engaging bulging portion 14, and when it passes through the engaging bulging portion 14, it is pressed down. It is pushed down by the engaging member 13 and faces the lower surface of the engaging bulging portion 14. Since one cycle is completed in this way, the structure 1 to be press-fitted can be press-fitted into the ground by repeatedly performing the expansion / contraction operation of the hydraulic jack 3.
【００１１】 また軟弱な地盤において、被圧入構造物１の沈下深度が大きくなると、被圧入 構造物１が突然沈下を起こすことがある。 この場合、下部グリッパー５および上部グリッパー６に油圧式クランプ装置を 組込んだ方式を採用すると、被圧入構造物１が突然沈下したとき、前記油圧式ク ランプ装置のロック状態の開放を自動的に行なうのが難しいので、種々のトラブ ルが発生する。 しかし、本発明の自動連続圧入装置の場合は、圧入用ロッド１６の形状と、下 部グリッパー５および上部グリッパー６におけるグリッパーベース８と、拡開用 ばね１１および押下用ばね１２と、押下用係合部材１３との機能で、下部グリッ パー５および上部グリッパー６ならびに液圧ジャッキ３は、被圧入構造物１と共 にスムーズに沈下する。Further, in soft ground, when the subsidence depth of the press-fitted structure 1 increases, the press-fitted structure 1 may suddenly settle. In this case, if a system in which a hydraulic clamp device is incorporated in the lower gripper 5 and the upper gripper 6 is adopted, when the press-fitted structure 1 suddenly sinks, the unlocked state of the hydraulic clamp device is automatically released. Because it is difficult to do, various traversals occur. However, in the case of the automatic continuous press-fitting device of the present invention, the shape of the press-fitting rod 16, the gripper base 8 in the lower gripper 5 and the upper gripper 6, the expanding spring 11 and the pressing spring 12, and the pressing member. With the function of the mating member 13, the lower gripper 5, the upper gripper 6 and the hydraulic jack 3 sink together with the press-fitted structure 1 smoothly.
