Description
本考案は、農作業や土木作業等に使用する様々な杭を打ち込む杭打器に関するものである。 The present invention relates to a pile driving device for driving various piles used for agricultural work or civil engineering work.
長い杭を地面に打ち込む場合には、槌等を使用すると脚立等の足場が必要であったり、まっすぐに杭を打ち込みにくいこと等が考えられる。
そこで、長い杭を打つ場合には、特許文献１に示すように、地面に立てた杭の上に細長い円筒状の本体を被せた状態で該本体を上下に動かして、杭の頭部を前記本体に設けられた平坦な天井部で打撃して杭を地面に打ち込む杭打器を使用すると便利である。
When driving a long pile into the ground, it is possible that a scaffold such as a stepladder is necessary or that it is difficult to drive the pile straight up.
Therefore, when hitting a long pile, as shown in Patent Document 1, the main body is moved up and down in a state where an elongated cylindrical main body is put on a pile standing on the ground, and the head of the pile is It is convenient to use a pile driver that strikes a flat ceiling provided on the main body and drives the pile into the ground.
このような従来の杭打器では、前記杭打器によって杭を打撃する時の労力を省くために、前記杭打器を重くする重り部材が前記本体に直接取り付けられている。 In such a conventional pile driver, a weight member that makes the pile driver heavy is attached directly to the main body in order to save labor when hitting the pile with the pile driver.
しかしながら、前記重り部材が前記本体に直接取り付けられているので、例えば、特に長い杭を前記本体に出し入れする場合や、前記杭打器を大きく振りかぶって杭を打つ場合等、前記本体を持ち上げる時に記杭打器の重心が高くなり、ぐらついて作業しにくいという問題がある。
また、前記本体に直接取り付けられた重り部材の位置を低くして前記杭打器の重心を低くするために、前記本体を長くすると、前記本体に杭を出し入れしにくいという問題が生じる。
However, since the weight member is directly attached to the main body, for example, when the main body is lifted, for example, when a long pile is put in and out of the main body, or when the pile is driven by swinging the pile driver greatly. There is a problem that the center of gravity of the pile driver becomes high and it is difficult to work by wobbling.
Moreover, if the length of the main body is lowered in order to lower the position of the weight member directly attached to the main body and lower the center of gravity of the pile driving device, there arises a problem that it is difficult to put the pile in and out of the main body.
本考案は、上記課題に鑑みてなされたものであり、長い杭を打つ場合であっても杭を出し入れしやすく、かつ重心が低く安定して杭打ち作業ができる杭打器を提供することを主な目的とする。 The present invention has been made in view of the above problems, and provides a pile driving device that is easy to put in and out a pile even when hitting a long pile, and has a low center of gravity and can stably perform pile driving work. Main purpose.
すなわち、本考案に係る杭打器は、先端から地面に打ち込む杭の基端を打撃する打撃部材と、該打撃部材の周縁部から伸びて杭の基端部にその軸方向に沿って進退可能に外側から嵌り込む筒状の本体と、該本体における前記打撃部材とは反対側の軸方向に、該本体と離間して設けられた重り部材とを具備したものである。 That is, the pile driving device according to the present invention is a striking member that strikes the base end of a pile driven into the ground from the tip, and extends from the periphery of the striking member and can advance and retreat along the axial direction to the base end of the pile. A cylindrical main body fitted into the main body from the outside, and a weight member provided apart from the main body in the axial direction of the main body opposite to the striking member.
このように構成した杭打器であれば、地面に杭を打ち込む場合に、前記杭打器を重くする前記重り部材が前記本体よりも下側に離間して配置されているので、前記本体への杭の出し入れしやすさを保ったまま杭打器の重心を低くすることができる。 In the case of a pile driver configured in this way, when the pile is driven into the ground, the weight member that makes the pile driver heavy is arranged at a lower side than the main body. The center of gravity of the pile driver can be lowered while maintaining ease of loading and unloading the pile.
前記重り部材に、前記本体と同軸の、杭が通る貫通孔と、該貫通孔に杭を側方から出し入れ可能な切り欠きとが形成されていれば、前記杭打器に杭を出し入れしやすい。
また、地面に杭を打つ場合に、前記本体だけでなく、前記本体よりも地面に近い前記重り部材に形成された前記貫通孔にも杭が通るので、この貫通孔の内側周面によって、前記杭打器が杭の軸から逸れにくくなり、前記本体を高く持ち上げて杭を打つ場合であっても、前記杭打器を杭に沿って動かして確実に打撃部で杭の基端を打撃することができる。
If the weight member is formed with a through hole that is coaxial with the main body and through which the pile passes and a notch that allows the pile to be taken in and out from the side, the pile is easily put in and out of the pile driver. .
Further, when hitting a pile on the ground, the pile passes not only through the main body but also through the through hole formed in the weight member closer to the ground than the main body. Even when the pile driver is difficult to escape from the axis of the pile and the main body is lifted high and the pile is hit, the pile hitter is moved along the pile to reliably hit the base end of the pile at the hitting portion. be able to.
具体的な実施態様としては、前記杭打器が、前記本体に対して前記重り部材を固定する支持部材をさらに具備したものが挙げられる。 As a specific embodiment, the pile driver further includes a support member that fixes the weight member to the main body.
前記支持部材の全部又は一部が手で握ることができる太さの棒状のものであれば、杭を打つ時に該支持部材を掴んで作業できるので、より杭打ち作業がしやすい。 If all or a part of the support member has a rod-like shape that can be grasped by hand, the support member can be gripped and operated when the pile is driven, so that the pile driving operation is easier.
前記杭打器が、前記本体部における前記打撃部材とは反対側の端面から軸方向に延伸するガイド部材をさらに具備したものであり、前記ガイド部材は前記重り部材の前記きり欠きと同じ方向に向かって開いた、側面から杭を出し入れ可能なスリットが設けられた部分筒状をなし、その内側周面が前記本体の前記進退動作を補助的に案内する案内面となっているものであれば、前記重り部材に形成された前記貫通孔の内側周面と同様に、この案内面によっても、前記杭打器が杭の軸からより逸れにくくすることができるので、前記杭打器をより杭に沿って動かしやすくなる。
また、杭を前記本体に入れるときに前記スリットから杭を出し入れることができるので、杭を前記本体に出し入れしやすい。
The pile driver further includes a guide member extending in an axial direction from an end surface of the main body portion opposite to the striking member, and the guide member is in the same direction as the notch of the weight member. As long as it has a partial cylindrical shape with slits that can be taken in and out from the side, and the inner peripheral surface is a guide surface that assists the advance / retreat operation of the main body. As with the inner peripheral surface of the through-hole formed in the weight member, this guide surface can also make the pile driving device more difficult to deviate from the axis of the pile. It becomes easy to move along.
Moreover, since a pile can be taken out and put in from the said slit when putting a pile into the said main body, it is easy to put a pile into and out of the said main body.
前記杭打器の具体的な実施態様としては、前記本体の形状が円筒状であるものが挙げられる。 As a concrete embodiment of the pile driver, one in which the shape of the main body is cylindrical can be mentioned.
本考案に係る杭打器によれば、地面に杭を打ち込む場合に、前記杭打器を重くする前記重り部材が前記本体よりも下側に離間して配置されているので、前記本体への杭の出し入れしやすさを保ったまま杭打器の重心を低くすることができる。 According to the pile driving device according to the present invention, when the pile is driven into the ground, the weight member that makes the pile driving device heavy is arranged at a lower side than the main body. The center of gravity of the pile driver can be lowered while maintaining ease of loading and unloading the pile.
以下に、本考案の実施の形態を図面を用いて説明する。
本実施形態に係る杭打器１は、例えば、農作業に使用される杭Ａを地面に打ち込むものである。
Embodiments of the present invention will be described below with reference to the drawings.
The pile driving device 1 according to the present embodiment drives, for example, a pile A used for farm work into the ground.
前記杭打器１は、図１に示すように、先端から地面に打ち込む杭Ａの基端を打撃する打撃部材１１と、該打撃部材１１の周縁部から伸びて杭Ａの基端部に進退可能に外側から嵌り込む筒状の本体１２と、前記杭打器１に取り付けられ該杭打器１を重くする重り部材１３と、該重り部材１３を前記本体１２に対して固定する支持部材１４とを具備したものである。 As shown in FIG. 1, the pile driving device 1 has a striking member 11 that strikes the base end of a pile A driven into the ground from the front end, and extends from the peripheral portion of the striking member 11 to advance and retreat to the base end portion of the pile A. A cylindrical main body 12 that can be fitted from the outside, a weight member 13 that is attached to the pile driving device 1 and makes the pile driving device 1 heavy, and a support member 14 that fixes the weight member 13 to the main body 12. Are provided.
前記杭打器１は、図１から図５に示すように、前記本体１２における前記打撃部材１１とは反対側の端面から軸方向に延伸したガイド部材１５をさらに具備したものである。 As shown in FIGS. 1 to 5, the pile driving device 1 further includes a guide member 15 extending in the axial direction from an end surface of the main body 12 opposite to the striking member 11.
前記打撃部材１１は、例えば、円盤状の鋼材である。
前記本体１２は、例えば、細長い円筒状の筒状体１２１であり、前記打撃部材１１は、例えば、この筒状体１２１の天蓋としてはめ込まれている。
The hitting member 11 is, for example, a disk-shaped steel material.
The main body 12 is, for example, an elongated cylindrical tubular body 121, and the hitting member 11 is fitted as a canopy of the tubular body 121, for example.
前記重り部材１３は、前記杭打器１全体を重くするものであり、例えば、直方体状の鋼材である。
前記重り部材１３には、前記本体１２の軸線上に、杭Ａが通る、例えば、円筒状の貫通孔１３Ｈが形成されており、この貫通孔１３Ｈに向かって該重り部材１３の側方から、前記貫通孔１３Ｈに杭Ａを出し入れ可能な切り欠き１３Ｓが形成されている。
The said weight member 13 makes the said pile driving device 1 whole heavy, for example, is a rectangular parallelepiped steel material.
The weight member 13 is formed with, for example, a cylindrical through hole 13H through which the pile A passes on the axis of the main body 12, and from the side of the weight member 13 toward the through hole 13H, A notch 13S into which the pile A can be taken in and out is formed in the through hole 13H.
前記支持部材１４は、例えば、前記本体１２に対して前記重り部材１３を該本体１２における前記打撃部材１１とは反対側の軸方向に、該本体１２と離間して固定するものである。
前記支持部材１４は、例えば、その全体が手で持つことができる太さのものであり、例えば円柱状の棒である。
For example, the support member 14 is configured to fix the weight member 13 to the main body 12 so as to be separated from the main body 12 in the axial direction of the main body 12 opposite to the striking member 11.
The support member 14 is of a thickness that can be held by hand as a whole, for example, a cylindrical rod.
前記支持部材１４は、例えば、前記筒状体１２１の側面に、前記筒状体１２１の軸方向に沿って該筒状体１２１を外側から挟むように、例えば、２本固定されており、前記筒状体１２１の軸方向において前記打撃部材１１とは反対側に伸びた先端部で前記重り部材１３を固定するものである。
本実施形態では、図１から図５に示すように、前記支持部材１４の一部が、前記筒状体１２１に固定されている部分で分岐している。
該分岐した支持部材１４の一方は、例えば、前記筒状体１２１に沿ってその軸方向に前記重り部材１３まで伸びており、他方は、例えば、前記筒状体１２１の軸方向に対して直角方向に、例えば、腕が入る程度の距離だけ前記筒状体１２１から離間した後、前記筒状体１２１の軸方向に沿って重り部材側に折れて、前記筒状体１２１と平行に重り部材１３まで伸びている。
これら分岐した支持部材１４は、前記重り部材１３と接する位置で再び合流するように構成されている。
For example, two supporting members 14 are fixed to the side surface of the cylindrical body 121, for example, so as to sandwich the cylindrical body 121 from the outside along the axial direction of the cylindrical body 121. The weight member 13 is fixed by a tip portion extending on the opposite side to the striking member 11 in the axial direction of the cylindrical body 121.
In the present embodiment, as shown in FIGS. 1 to 5, a part of the support member 14 is branched at a portion fixed to the cylindrical body 121.
One of the branched support members 14 extends, for example, to the weight member 13 in the axial direction along the cylindrical body 121, and the other is, for example, perpendicular to the axial direction of the cylindrical body 121. For example, after being separated from the cylindrical body 121 by a distance that allows an arm to enter, the weight member is bent along the axial direction of the cylindrical body 121 to the weight member side and parallel to the cylindrical body 121. It extends to 13.
The branched support members 14 are configured to join again at a position in contact with the weight member 13.
前記ガイド部材１５は、例えば、図２に示すように、杭Ａを側方から出し入れ可能なスリットＳが形成された部分筒状のものである。
このスリットＳは、前記重り部材１３に形成された切り欠き１３Ｓと同じ方向に開口するものである。
For example, as shown in FIG. 2, the guide member 15 has a partial cylindrical shape in which a slit S through which the pile A can be taken in and out is formed.
The slit S opens in the same direction as the notch 13S formed in the weight member 13.
また、前記ガイド部材１５は、その内側周面が本体１２の前記進退動作を補助的に案内する案内面となっているものである。
前記ガイド部材１５は、例えば、円筒状の筒を軸方向に沿って半分に割ったような形状をしている。
前記ガイド部材１５の軸方向の長さは、特に限定されないが、例えば、図２に示すように前記筒状体１２１よりも短いものであっても良い。
Further, the guide member 15 has an inner peripheral surface serving as a guide surface for assisting in the advance / retreat operation of the main body 12.
The guide member 15 has, for example, a shape obtained by dividing a cylindrical tube in half along the axial direction.
The length of the guide member 15 in the axial direction is not particularly limited. For example, the guide member 15 may be shorter than the cylindrical body 121 as shown in FIG.
このように構成された杭打器１を用いて杭Ａを打つ手順を以下に説明する。
まず、杭Ａを打ち込みたい場所に仮打ちして自立させる。
次に、前記杭打器１の支持部材１４を手で持って、前記杭打器１を持ち上げ、杭Ａの基端部を前記筒状体１２１の内部に差し込む。
このとき、杭Ａの基端、すなわち杭頭が前記ガイド部材１５の内側周面に沿って前記筒状体１２１に入るように、前記ガイド部材１５に形成された前記スリットＳから杭Ａを入れるとよい。
The procedure for hitting the pile A using the pile driver 1 configured in this way will be described below.
First of all, the pile A is provisionally struck to the place where it is desired to be driven, and is made independent.
Next, the support member 14 of the pile driver 1 is held by hand, the pile driver 1 is lifted, and the base end portion of the pile A is inserted into the cylindrical body 121.
At this time, the pile A is inserted from the slit S formed in the guide member 15 so that the base end of the pile A, that is, the pile head enters the cylindrical body 121 along the inner peripheral surface of the guide member 15. Good.
杭Ａの角度を確認した後、前記支持部材１４を持って前記杭打器１を杭Ａに沿って持ち上げ、前記支持部材１４を持ったまま前記杭打器１を自由落下させる、又は加速度をつけながら落として、打撃部材１１で杭頭を打撃し、杭Ａを打ち込む。
前記杭打器１を持ち上げて落とす動作を繰り返して、杭Ａを打ち込みたい深さまで打ち込む。
このようにして杭Ａを目的の深さまで打ち込んだ後、前記支持部材１４を持って前記杭打器１を持ち上げ、杭Ａの基端部からはずす。
このとき、前記ガイド部材１５に形成された前記スリットＳから杭Ａを出すとよい。
After confirming the angle of the pile A, the pile driving device 1 is lifted along the pile A by holding the support member 14, and the pile driving device 1 is dropped freely while holding the support member 14, or acceleration is increased. While being attached, the pile head is hit with the hitting member 11 and the pile A is driven.
The operation of lifting and dropping the pile driver 1 is repeated, and the pile A is driven to a depth where it is desired to be driven.
After driving the pile A to a desired depth in this way, the pile driving device 1 is lifted by holding the support member 14 and removed from the base end portion of the pile A.
At this time, the pile A may be taken out from the slit S formed in the guide member 15.
本実施形態に係る杭打器１によれば、前記筒状体１２１と前記重り部材１３とが棒状の支持部材１４を介して離間して固定されており、杭Ａを打つ地面に打ち込む場合に、前記重り部材１３が前記筒状体１２１よりも下側になるように固定されているので、前記筒状体１２１への杭Ａの出し入れしやすさを保ったまま、前記杭打器１の重心を低くすることができる。 According to the pile driving device 1 according to the present embodiment, when the cylindrical body 121 and the weight member 13 are spaced apart and fixed via a rod-like support member 14 and driven into the ground where the pile A is driven. Since the weight member 13 is fixed so as to be lower than the cylindrical body 121, the pile driving device 1 of the pile driving device 1 is maintained while maintaining ease of loading and unloading the pile A into the cylindrical body 121. The center of gravity can be lowered.
前記ガイド部材１５に前記スリットＳが形成されているので、杭Ａを前記筒状体１２１に差し込むときに、このスリットＳから杭Ａを入れることで、杭Ａを前記ガイド部材１５の内側周面に沿ってスムーズに前記筒状体１２１に差し込むことができ、杭Ａを差込みやすい。 Since the slit S is formed in the guide member 15, when the pile A is inserted into the cylindrical body 121, the pile A is inserted from the slit S so that the pile A is connected to the inner peripheral surface of the guide member 15. Can be smoothly inserted into the cylindrical body 121 and the pile A can be easily inserted.
また、前記筒状体１２１から打設し終わった杭Ａを出すときにも前記ガイド部材１５に形成された前記スリットＳから杭Ａを出すことで、前記杭打器１を持ち上げる高さを低く抑えることができる。 Further, when the pile A that has been driven from the cylindrical body 121 is taken out, the pile A is lifted from the slit S formed in the guide member 15 so that the height of lifting the pile driver 1 is lowered. Can be suppressed.
前記ガイド部材１５の内側周面が前記本体１２の前記進退動作を補助的に案内する案内面となっており、この案内面を杭Ａに沿わせて前記杭打器１を動かすことができるので、前記杭打器１が杭Ａの軸から逸れにくくなり、前記杭打器１を大きく振りかぶって杭Ａを打つ場合であっても、前記杭打器１を杭Ａに沿って動かして確実に打撃部材１１で杭Ａの基端を打撃することができる。
前記重り部材１３に、前記ガイド部材１５に形成された前記スリットＳと同じ方向に開口した、杭Ａを側方から出し入れ可能な前記切り欠き１３Ｓが形成されているので、前記重り部材１３が前記筒状体１２１と離間して配置されていても、前記杭打器１に杭Ａを出し入れしやすい。
前記筒状体１２１から離間して設けられた前記重り部材１３に形成された前記貫通孔１３Ｈの内側周面を杭Ａに沿わせて前記杭打器１を動かすことができるので、前記杭打器１を杭Ａの軸からより逸れにくくすることができる。
The inner peripheral surface of the guide member 15 serves as a guide surface that assists in the advance / retreat operation of the main body 12, and the pile driver 1 can be moved along the guide surface along the pile A. Even if the pile driver 1 is less likely to deviate from the axis of the pile A and the pile driver 1 is shaken largely and hits the pile A, the pile driver 1 is moved along the pile A reliably. The base end of the pile A can be hit with the hitting member 11.
The weight member 13 is formed with the notch 13S that opens in the same direction as the slit S formed in the guide member 15 and allows the pile A to be taken in and out from the side. Even if the pile body 121 is disposed apart from the cylindrical body 121, the pile A can be easily put in and out of the pile driver 1.
Since the pile driving device 1 can be moved along the inner circumferential surface of the through-hole 13H formed in the weight member 13 provided away from the cylindrical body 121 along the pile A, the pile driving The vessel 1 can be made more difficult to escape from the axis of the pile A.
前記筒状体１２１が円筒状のものであるので、杭Ａが前記筒状体１２１の内部に引っかかりにくく、杭Ａを打つ時に杭Ａに沿って前記杭打器１を動かしやすい。 Since the cylindrical body 121 is cylindrical, the pile A is not easily caught inside the cylindrical body 121, and the pile driver 1 can be easily moved along the pile A when the pile A is hit.
前記筒状体１２１に対して重り部材１３を固定する前記支持部材１４の全部が手で握れる太さの棒状のものであるので、地面に杭Ａを打つ場合に、前記杭打器１を上下動しやすい、また仮打ちした杭Ａに前記杭打器１を設置する時や、打設した杭Ａから前記杭打器１を外す時等に前記杭打器１を持ち上げやすい。
また、前記支持部材１４全部が手で握れる太さの棒状のものであるので、地面に杭Ａを打つ場合に、前記重り部材１３付近、すなわち前記杭打器１の下端を持って、前記杭打器１を高く持ち上げることができ、農作業等に使用される２．５ｍ程度の特に長い杭Ａであっても、脚立等を使用することなく簡単に打設することが可能である。
Since all of the support member 14 that fixes the weight member 13 to the cylindrical body 121 is a rod-shaped member that can be grasped by hand, when the pile A is hit on the ground, the pile driver 1 is moved up and down. The pile driver 1 can be easily lifted when the pile driver 1 is installed on the pile A which is easily moved or when the pile driver 1 is removed from the pile A which has been installed.
In addition, since the support member 14 is a rod-shaped member that can be grasped by hand, when the pile A is hit on the ground, the pile member 1 is held near the weight member 13, that is, the lower end of the pile driver 1. The hitting device 1 can be lifted high, and even a particularly long pile A of about 2.5 m used for farm work or the like can be easily placed without using a stepladder or the like.
前記支持部材１４の一部が前記筒状体１２１から、例えば、腕が入る程度の距離だけ外側に離れた場所にも配置されているので、前記支持部材１４を持ちやすく、前記杭打器１を操作しやすい。 Since a part of the support member 14 is also arranged at a position away from the cylindrical body 121 by, for example, a distance that allows an arm to enter, the support member 14 can be easily held, and the pile driver 1 Easy to operate.
なお、本考案は本実施形態に限られない。
例えば、本実施形態では、前記杭打器１を使用する前に杭Ａを仮打ちしたが、本考案にかかる杭打器１によれば、杭Ａを仮打ちしない方法でも杭Ａを打設できる。
この場合には、前記杭打器１を地面に寝かせた状態で、杭Ａの基端部を前記本体１２に差し込む。
次に、杭Ａを打設したい場所に杭Ａの先端をあて、ここを支点として前記杭打器１の前記重り部１３に近い部分の前記支持部材１４を持って前記杭打器１をひっぱり起こす。
The present invention is not limited to this embodiment.
For example, in the present embodiment, the pile A is provisionally struck before the pile driver 1 is used. However, according to the pile driver 1 according to the present invention, the pile A is also driven by a method in which the pile A is not provisionally struck. it can.
In this case, the base end portion of the pile A is inserted into the main body 12 with the pile driver 1 laid on the ground.
Next, the tip of the pile A is applied to a place where the pile A is to be placed, and the pile driving device 1 is pulled by holding the support member 14 near the weight portion 13 of the pile driving device 1 with this point as a fulcrum. Wake up.
前記杭打器１をまっすぐに立てた後は、前述した方法と同じように、杭Ａに沿って前記杭打器１を上下動させて前記打撃部材１１で杭頭を打撃して杭Ａを打ち込み、前記杭打器１を外せば、打設が完了する。
このような打設方法の場合にも、前記重り部材１３が地面に近い場所にあることで、杭Ａを差し込んだ前記杭打器１をひっぱり起こす時に、より軽い力で簡単に起こすことができる。
