（従来の技術）
従来杭打用のハンマーとしては、８トン程度の鋼塊（モ
ンケン）が用いられている。しかしながら、従来のハン
マーにおいては、杭頭を打撃した際の衝撃が吸収されず
、大きな衝撃音が発生する為、騒音公害の原因となって
いた。(Prior Art) Conventionally, a steel ingot (monken) of about 8 tons is used as a hammer for pile driving. However, with conventional hammers, the impact when hitting the pile head is not absorbed and a large impact sound is generated, causing noise pollution.
（発明の構成）
この発明の杭打用ハンマーは、上下を閉塞し、底を板体
とし、周壁を柔軟材とした収容体内に、流動固形物を装
入して構成されている。(Structure of the Invention) The pile driving hammer of the present invention is constructed by charging a fluid solid material into a container whose top and bottom are closed, whose bottom is a plate, and whose peripheral wall is made of a flexible material.
前記板体は十分な強度、耐久性のある材質、通常は鋼板
が用いられ、前記杭打板に柔軟材製の周壁を連設して収
容体を構成する。前記柔軟材は、変形可能に編成された
網又は布を用い、ピストンによる加圧を行う場合は上部
も板体で閉塞する。The plate body is made of a material with sufficient strength and durability, usually a steel plate, and a peripheral wall made of a flexible material is connected to the piling plate to constitute the container. As the flexible material, a deformably knitted net or cloth is used, and when pressure is applied by a piston, the upper part is also closed with a plate.
前記流動固形物は、大きさを問わないのであって、粉体
ないし大塊を用いることができ、またその形状は球体の
地条面体とすることもできるが、実用上１ＣＩＩｌない
し数ｃｍ径の球体が適当である。また、材質としては鋼
が一般的であるが、その他の大比重の材質であれば用い
ることができる。The size of the fluidized solid does not matter, and it can be a powder or a large lump, and its shape can also be a spherical shape, but in practice it can be of a diameter of 1 cm to several cm. A sphere is suitable. Further, although steel is generally used as the material, any other material with a large specific gravity can be used.
前記流動固形物の総重量は、適宜選択して定めるものと
するが、杭に所定の衝撃力を与える必要上通常８１〜ン
以上は必要であろう。尚、流動固形物は、杭打時の衝撃
を吸収する必要上、２個以上とする。また流動固形物の
装入量は収容体の内容積の５０％ないし１００％程度が
適当である。The total weight of the fluidized solids shall be selected and determined as appropriate, but it will normally be required to be at least 81 mm in order to apply a predetermined impact force to the pile. Note that two or more fluid solids are required to absorb the impact during pile driving. Further, the amount of fluidized solid to be charged is suitably about 50% to 100% of the internal volume of the container.
この発明の杭打用ハンマーは、抗頭の打撃時に収容体が
幅方向にｌ膨大変形するが、その際に流動固形物が滑り
移動容易となるよう、流動固形物外周に油をイ」着して
おくことが望ましい。In the pile driving hammer of the present invention, oil is applied to the outer periphery of the fluid solid so that the container expands and deforms in the width direction when the pile head is hit, so that the fluid solid can easily slide and move. It is desirable to keep it.
（発明の作用）
この発明の杭打用ハンマーは、従来のモンケンと同様、
ワイヤーで吊り上げた後、急速落下させることにより、
又ルまピストンに連結して杭頭を打撃して杭を埋設する
ものである。ここで、打撃時の衝撃力は流動固形物の移
動によって吸収されるので騒音は低下する。更に収容体
が変形すれば、流動固形物の移動量が増して衝撃力はよ
り吸収されるので、騒音は一層低下する。(Action of the invention) The pile driving hammer of this invention is similar to the conventional MONKEN,
By hoisting it up with a wire and then dropping it rapidly,
It connects to a piston and hits the pile head to bury the pile. Here, since the impact force at the time of impact is absorbed by the movement of the fluid solid, the noise is reduced. Furthermore, if the container is deformed, the amount of movement of the fluid solids increases and the impact force is absorbed more, so that the noise is further reduced.
（実施例１） 以下この発明の実施例を図面に基いて説明する。(Example 1) Embodiments of the present invention will be described below with reference to the drawings.
鋼製の底板１に鉄筋ｗ４製の周壁２及び上板を連設して
構成された収容体３内に流動固形物として周面に油が付
着された１ｃａ＋径程度の鋼球４を８トンないし１０ｔ
−ン程度装入してこの発明の杭打用ハンマーが構成され
ている。前記収容体３は装入された鋼球４が容積のほぼ
１００％となる大きさとしてあり、前記鉄筋網は伸縮変
形可能に編成しである。8 tons of steel balls 4 having a diameter of about 1 ca + diameter and having oil attached to the circumferential surface as a fluid solid are placed in a container 3 consisting of a bottom plate 1 made of steel, a peripheral wall 2 made of reinforcing steel W4, and a top plate connected to each other. or 10t
The pile driving hammer of the present invention is constructed by charging approximately 1. The container 3 has a size such that the loaded steel balls 4 occupy almost 100% of its volume, and the reinforcing bar net is arranged to be expandable and deformable.
次に上記実施例に示す杭打用ハンマーの作用、効果を説
明する。Next, the functions and effects of the pile driving hammer shown in the above embodiment will be explained.
収容体３の上部を吊り上用ワイヤー５に連結し所定高さ
まで吊り上げた後、通常の要領で急速落下させて杭頭６
を打撃する。打撃時において、収容体３内の鋼球４は矢
示７方向へ滑り移動し、打撃時の衝撃ツノは吸収される
。然して従来のモンケンに比較して、騒音の発生は低減
する。After connecting the upper part of the container 3 to the lifting wire 5 and lifting it up to a predetermined height, it is rapidly dropped in the usual manner to reach the pile cap 6.
to hit. At the time of impact, the steel ball 4 within the container 3 slides in the direction of arrow 7, and the impact horn at the time of impact is absorbed. However, noise generation is reduced compared to conventional Monken.
上記実施例によれば、鋼球４の装入量を収容体３の内容
積のほぼ１００％としたので、打撃時において鋼球４が
跳ね上がることがなく、打撃効率の低下を可及的に防止
することができる。尚、この場合にａ３いても、モンケ
ンと同様の条件で用いた場合、打撃効率は２０％程度低
下するが、重量を増大さけたり又は高所から落下するこ
とによりカバーすることができる。According to the above embodiment, since the amount of steel balls 4 charged is approximately 100% of the internal volume of the container 3, the steel balls 4 do not jump up during impact, and the decrease in impact efficiency is minimized. It can be prevented. In this case, even if A3 is used, the hitting efficiency will decrease by about 20% when used under the same conditions as Monken, but this can be compensated for by avoiding an increase in weight or by falling from a high place.

に下向ぎの力を与えることができる。The pile driving hammer shown in this embodiment has a piston rod 1
2, and if the charged amount of steel balls 4 is 50% to 80%, the impact pressure due to the pressurization of the piston rod 12 and the static pressure due to the falling of the steel balls 4 will be reduced. This allows a downward force to be applied to the pile.
尚、この実施例においても、鎖線のように変形すること
、実施例１と同様である。Note that this embodiment is also similar to the first embodiment in that it is deformed as shown by the chain line.
