Description

本発明は、フェンスなどの支柱パイプを基礎杭パイプに外挿して接続し、かつ固定する支柱パイプの固定構造に関する。   The present invention relates to a fixing structure of a supporting pipe that connects and fixes a support pipe such as a fence to an foundation pile pipe.

従来、杭パイプの上部に支柱パイプのような他のパイプを接続する構造として例えば特許文献１に記載された構造が知られている。これは、杭パイプの上部に接続されるパイプの下端部に、杭パイプの内径より小径の段付き小径部を形成し、この小径部を杭パイプの上部に差し込んで当該パイプを接続するものである。   Conventionally, for example, a structure described in Patent Document 1 is known as a structure in which another pipe such as a support pipe is connected to an upper portion of a pile pipe. This is to form a stepped small diameter part that is smaller in diameter than the inner diameter of the pile pipe at the lower end of the pipe connected to the upper part of the pile pipe, and connect this pipe by inserting this small diameter part into the upper part of the pile pipe. is there.

特開２０１１−１８２６４９JP2011-182649

特許文献１に記載の接続構造においては、上部のパイプが容易に上方へ抜けてしまうという課題がある。
したがって、本発明は、杭パイプの上部に外挿することにより支柱パイプを接続したら、そのままで上方へ確実に抜け止めされる支柱パイプの固定構造を提供することを目的としている。 In the connection structure described in Patent Document 1, there is a problem that the upper pipe easily comes out upward.
Therefore, an object of the present invention is to provide a fixing structure of a column pipe that can be reliably prevented from coming off as it is when the column pipe is connected by extrapolating the upper part of the pile pipe.

以下、添付図面の符号を参照して説明するが、本発明はこれに限定されるものではない。
上記課題を解決するための、本発明の支柱パイプの固定構造は、地上に固定される基礎杭パイプ１と、上方拡大の円錐台形状で、基礎杭パイプ１の上端にこれと同心的に固着されるテーパ駒４と、テーパ駒４の外周に巻き回され、下端が基礎杭パイプ１の上端に係止され、上端がテーパ駒４の上部外周に伸縮動可能に係止される楔ばね７と、下端部が、楔ばね７、テーパ駒４及び基礎杭パイプ１に外挿され、かつ下端が所定位置で下方向に止められ、基礎杭パイプ１と同心的に上方へ伸びる支柱パイプ８とを具備する。楔ばね７の上端部は、支柱パイプ８を外挿するとき、支柱パイプ８の内周に接触して下方へ圧縮されることによって支柱パイプ８の外挿を許容し、かつテーパ駒４の上部外周と支柱パイプ８の内周との間に介在することで、相互の接触抵抗により、支柱パイプ８を基礎杭パイプ１から上方へ抜け止め可能に構成される。 Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
In order to solve the above problems, the support structure of the pillar pipe of the present invention has a foundation pile pipe 1 fixed on the ground, and a truncated conical shape that expands upward, and is fixed concentrically to the upper end of the foundation pile pipe 1. A taper piece 4 wound around the outer periphery of the taper piece 4, a lower end is engaged with the upper end of the foundation pile pipe 1, and an upper end is engaged with the upper outer periphery of the taper piece 4 so as to be telescopically movable. A pillar pipe 8 whose lower end is extrapolated to the wedge spring 7, the taper piece 4 and the foundation pile pipe 1 and whose lower end is stopped downward at a predetermined position and extends upward concentrically with the foundation pile pipe 1; It comprises. When the support pipe 8 is extrapolated, the upper end portion of the wedge spring 7 contacts the inner periphery of the support pipe 8 and is compressed downward to allow the support pipe 8 to be extrapolated. By interposing between the outer periphery and the inner periphery of the support pipe 8, the support pipe 8 can be prevented from coming off from the foundation pile pipe 1 due to mutual contact resistance.

本発明の支柱パイプの固定構造においては、支柱パイプを杭パイプの上部に外挿するだけで容易に接続することができ、そのままで上方へ確実に抜け止めされる。   In the support structure of the support pipe according to the present invention, the support pipe can be easily connected only by extrapolating the support pipe to the upper part of the pile pipe, and it is reliably prevented from coming off as it is.

本発明に係る支柱パイプの固定構造を示す断面図である。It is sectional drawing which shows the fixing structure of the support pipe which concerns on this invention.

図面を参照して本発明の実施の形態を説明する。
図１において、基礎杭パイプ１は、下部が地中に打ち込まれ、やや上細りの上部が地上に起立している。基礎杭パイプ１は、中心にねじ孔２を有する蓋３で上端が閉じられる。 Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, the foundation pile pipe 1 has a lower portion driven into the ground, and a slightly upper upper portion standing on the ground. The foundation pile pipe 1 is closed at the upper end by a lid 3 having a screw hole 2 in the center.

上方拡大の円錐台形状のテーパ駒４が、基礎杭パイプ１の蓋３の上に、これと同心的に、ボルト５で固着される。テーパ駒４は、下端の外径が蓋３の外径よりやや小さく、中央にボルト孔６を有する。   An upwardly expanding truncated cone-shaped taper piece 4 is fixed on the lid 3 of the foundation pile pipe 1 with a bolt 5 concentrically therewith. The taper piece 4 has an outer diameter at the lower end slightly smaller than the outer diameter of the lid 3 and has a bolt hole 6 at the center.

テーパ駒４の外周に楔ばね７が巻き回される。楔ばね７は、テーパ駒４の外周に沿うように、その巻き直径が下方に向かって徐々に小さくなっている。楔ばね７の下端は、基礎杭パイプ１の蓋３の上に係止され、上端は、テーパ駒４の上部外周に伸縮できるように係止される。   A wedge spring 7 is wound around the outer periphery of the taper piece 4. The winding diameter of the wedge spring 7 gradually decreases downward along the outer periphery of the taper piece 4. The lower end of the wedge spring 7 is locked on the lid 3 of the foundation pile pipe 1, and the upper end is locked so that it can expand and contract on the upper outer periphery of the taper piece 4.

支柱パイプ８は、基礎杭パイプ１及びテーパ駒４の上端部の直径よりわずかに大きい内径を有する。支柱パイプ８は、下端部が、楔ばね７、テーパ駒４及び基礎杭パイプ１に外挿され、かつ下端がスペーサ９で下方向に止められ、基礎杭パイプと同心的に上方へ伸びる。支柱パイプ８の内周とテーパ駒４の上端部外周との間の隙間Ｓは、楔ばね７の直径より小さくなるように設定される。   The support pipe 8 has an inner diameter slightly larger than the diameters of the upper ends of the foundation pile pipe 1 and the taper piece 4. The column pipe 8 has a lower end portion that is extrapolated to the wedge spring 7, the taper piece 4, and the foundation pile pipe 1, and a lower end that is stopped downward by the spacer 9, and extends upward concentrically with the foundation pile pipe. A gap S between the inner periphery of the support pipe 8 and the outer periphery of the upper end of the taper piece 4 is set to be smaller than the diameter of the wedge spring 7.

基礎杭パイプ１上に楔ばね７とテーパ駒４を取り付けた状態で、上方から支柱パイプ８を外挿していくと、その下端部内周が楔ばね７に接触してこれを下方へ圧縮し、楔ばね７の上端部をテーパ駒４の小径部分まで押し下げつつ下降し、下端がスペーサ９に当接して止まる。   With the wedge spring 7 and the taper piece 4 mounted on the foundation pile pipe 1, when the support pipe 8 is extrapolated from above, the inner periphery of the lower end thereof contacts the wedge spring 7 and compresses it downward. The wedge spring 7 is lowered while pushing down the upper end portion of the wedge piece 7 to the small diameter portion of the taper piece 4, and the lower end comes into contact with the spacer 9 and stops.

この状態で、楔ばね７は復元し、テーパ駒４の上部外周と支柱パイプ８の内周との間に楔ばね７の上端部が介在する。テーパ駒４の上部外周と支柱パイプ８の内周との間に楔ばね７の上端部が噛み合うことで、支柱パイプ８を基礎杭パイプ１から上方へ抜け止めする。   In this state, the wedge spring 7 is restored, and the upper end portion of the wedge spring 7 is interposed between the upper outer periphery of the taper piece 4 and the inner periphery of the support pipe 8. The upper end of the wedge spring 7 meshes between the upper outer periphery of the taper piece 4 and the inner periphery of the support pipe 8, thereby preventing the support pipe 8 from coming off from the foundation pile pipe 1.

なお、基礎杭パイプ１は打ち込み式のものでなくても本発明を適用できる。基礎杭パイプ１上へのテーパ駒４の固定方法は、種々の公知のものを採用できる。支柱パイプ８の下端は、地面に突き付けてもよいし、基礎杭パイプ１の外周に固定された適宜の固定部材に突き付けてもよい。   In addition, even if the foundation pile pipe 1 is not a driving type, the present invention can be applied. As the fixing method of the taper piece 4 on the foundation pile pipe 1, various known methods can be adopted. The lower end of the support pipe 8 may be pressed against the ground or may be pressed to an appropriate fixing member fixed to the outer periphery of the foundation pile pipe 1.
