Description
【考案の詳細な説明】 本考案は杭打機のリーダに関するものである。[Detailed explanation of the idea] The present invention relates to a leader for a pile driver.
第１図は従来の杭打機の全体正面図を表わすもので、こ
れに示される形式の杭打機は本体１、リーダ２、ガイド
パイプ３、モンケン６等より構成される。FIG. 1 shows an overall front view of a conventional pile driver, and the type of pile driver shown in this figure is composed of a main body 1, a leader 2, a guide pipe 3, a control lever 6, and the like.
杭７はガイドパイプ３を案内にして、モンケン６を落下
させ、その衝撃によって打設される。The pile 7 is driven by the impact of dropping the Monken 6 using the guide pipe 3 as a guide.
ところがガイドパイプ３は杭打機の安定を計るため中空
パイプを使用し、重量を軽減しである。However, the guide pipe 3 uses a hollow pipe in order to stabilize the pile driver and reduce its weight.
しかしながら杭７を打設するとき、モンケン６に装着さ
れている案内金６ａによって、ガイドパイプ３は、杭７
の反力が大きくなる下部で変形や損傷が激しく、その補
修には多くの時間を費したり、作業の能率を著しく低下
させるため改善が望まれていた。However, when driving the pile 7, the guide pipe 3 is moved to the pile 7 by the guide metal 6a attached to the Monken 6.
The lower part, where the reaction force is greater, is severely deformed and damaged, and repairs are time-consuming and significantly reduce work efficiency, so improvements have been desired.
本考案は、上記不都合を解消するためになされたもので
あって、ガイドパイプ３の中空部にセメントモルタル等
の固形材を充填して防止するものである。The present invention has been made to solve the above-mentioned disadvantages, and is prevented by filling the hollow portion of the guide pipe 3 with a solid material such as cement mortar.
次に本考案の一実施例を第２図乃至第４図により説明す
る。Next, one embodiment of the present invention will be described with reference to FIGS. 2 to 4.
第２図は本考案の杭打機の全体正面図を表わし、符号１
〜７で示すものは第１図記載のものと同様である。Figure 2 shows an overall front view of the pile driver of the present invention, and is denoted by reference numeral 1.
Those indicated by 7 to 7 are the same as those shown in FIG.
本実施例のリーダ２の長さ１５ｍに対し、ガイドパイプ
３の変形の激しい下部７ｍの長さにわたり、ガイドパイ
プ３の中空部にセメントモルタル８を充填したものであ
る。The hollow part of the guide pipe 3 is filled with cement mortar 8 over the length of the lower part of the guide pipe 3, which is 7 m long, where the deformation is severe, compared to the length of the leader 2 of this embodiment, which is 15 m.
第３図および第４図は第２図Ａ部詳細図を表わす。3 and 4 show detailed views of section A in FIG. 2.
案内爪４は上部リーダ２ａ、中間リーダ２ｂ。The guide claws 4 include an upper leader 2a and an intermediate leader 2b.
下部リーダ２ｃを結合するとき、その両者を確実に案内
結合するためのもので、ガイドパイプ３ａｔ３ｂの下端
部に圧入固定してあり、該案内爪４の嵌入化を残してセ
メントモルタル８を充填する。When connecting the lower leader 2c, it is used to guide and connect the two reliably, and is press-fitted and fixed to the lower end of the guide pipe 3at3b, and the cement mortar 8 is filled with the guide claw 4 left in place. .
下部ガイドパイプ３ｃの下端部には、セメントモルタル
８の流出を防止するための塞ぎ板５を設けである。A closing plate 5 is provided at the lower end of the lower guide pipe 3c to prevent the cement mortar 8 from flowing out.
以上のような構成であって、これにより杭７を打設する
ときの反力を大きく受けるリーダ２の下部を補強するこ
とができこの結果、杭打機の安定をそこなうことなく、
リーダ２の寿命を延長させ、材料費の低減等に著しい効
果がある。With the above configuration, it is possible to reinforce the lower part of the leader 2 which receives a large reaction force when driving the pile 7, and as a result, without impairing the stability of the pile driver,
This has a significant effect on extending the life of the reader 2 and reducing material costs.
尚セメントモルタルを充填する長さは、リーダの使用目
的、型式、全高などに応じて適宜選定すればよく、充填
材についても本実施例に限定されるものでなく、例えば
硬質プラスチック等を使用しても良い。The length to be filled with cement mortar may be appropriately selected depending on the purpose of use, model, overall height, etc. of the reader, and the filling material is not limited to this example. For example, hard plastic or the like may be used. It's okay.
