Description

【０００１】
【発明の属する技術分野】
本発明は、地面に杭を打ち込み、これにロープを掛けて引っ張る時に使用する杭と、地面に柱を立てる時に使用する、柱立て台に関するものである。
【０００２】
【従来の技術】
先ず従来の杭の場合は、図３（イ）に示す如く、上部を輪にした鉄の棒を、地面に打ち込むか、図３（ロ）に示す如く、棒の部分を螺旋状にしたものを、地面に捩じ込んで、輪にロープを掛けて、テント等を引っ張っている。
【０００３】
次に従来の柱立て台は、図４（イ）に示す如く、中心に穴があいた台をコンクリートで作り、これを地面に置いて、穴の中に旗竿を立てたり、柱を立てて物干し台にしている。このコンクリートの台は重いので、持ち運びし易くする為に、同じ形の台をポリ容器で作り、使用する時に中に水を入れたり、又は図４（ロ）に示す如く鉄板に鉄のパイプを溶接した台を作り、これに傘の柄を差込んで、ビーチパラソル立て等にしている。
【０００４】
【発明が解決しようとする課題】
先ず従来の棒状の杭は抜け易く、螺旋状の杭は高価なので、本発明は、安くて抜け難い杭を提供しようとするものである。
【０００５】
次に従来の柱立て台は、コンクリートの台は重くて運搬し難く、ポリ容器の台や鉄製の台も、かさ張って運搬し易いとは言えない。この為本発明は、軽くて運搬し易い柱立て台を、提供しようとするものである。
【０００６】
【課題を解決するための手段】
ここで本出願人は先に、平鋼を捩った時に、ねじりピッチがどこも均一で真っ直ぐにねじる方法を発明し、特願平 9-12306号により出願済みである。本発明はこの方法により製作したねじり平鋼をアンカーとして使用し、地面に捩じ込む事にした。
【０００７】
先ず杭として使用するアンカーは、図１（イ）に示す如く、平鋼を捩った、ねじり平鋼の上部に鉄棒が通る穴をあけ、棒を穴に差込んで、ねじり平鋼を回して地面に捩じ込み、穴にロープを通して引っ張れば、安くて抜け難い杭になる。
【０００８】
次に柱立て台として使用するアンカーは、図２に示す如く、ねじり平鋼にパイプを接続して溶接し、パイプの上部に、鉄棒が通る穴を貫通し、棒を穴に差込んで回せば、ねじり平鋼は簡単に地面に捩じ込まれて行く。尚この場合、ねじり平鋼とパイプの間に鉄の鍔を溶接すれば、これ以上捩じ込まれないので位置が決まり、パイプが傾くのを防ぐ効果がある。このようにして地面に立てたパイプは、抜け難く、倒れ難くい為、これに柱を差込んで立てればよい。このようにすれば、軽くて運搬し易い柱立て台が出来る。
【０００９】
【発明の実施の形態】
先ず杭として使用するアンカーを、図１（イ）に示すと、長いねじり平鋼を、適当に切断したねじり平鋼（１）を用意し、一方の先端近くに鉄棒が通る穴（２）をあけ、もう一方の先端を、地面にぬかり易いように少し尖らせると、従来の杭に代わり使用出来るアンカーになる。又は図１（ロ）に示す如く、平鋼の部分を少し残して、その先を捩じったねじり平鋼（１’）を用意し、平鋼の部分に鉄棒が通る穴（２）をあけ、ねじり平鋼の先を少し尖らせても良い。このアンカーの使用法は、適当な鉄棒を穴に差込んで回せば、地面に捩じ込まれるので、穴にロープを通して引っ張る事が出来る。
【００１０】
次に柱立て台として使用するアンカーを、実施例として図２に示すと、ねじり平鋼の幅とほぼ同じ直径のパイプ（３）を用意し、パイプの端に平鋼の厚みの幅の切込みを入れる。そしてこの切込みに、図１（ロ）に示したねじり平鋼（１’）を差込んで溶接し、先端を少し尖らせる。そしてパイプの先端近くに、鉄棒を差込む穴（２）を貫通し、次にその付近に別の穴を開け、穴にナット（４）を溶接して蝶ボルト（５）を取り付ける。最後に鉄板で鍔（６）を作り、ねじり平鋼とパイプの間に溶接すれば、従来の柱立て台に代わり使用出来るアンカーになる。
【００１１】
このアンカーの使用法は、アンカーを地面に立て、適当な鉄棒を穴に差込んで回せば、アンカーは鍔の所まで捩じ込まれて立てる事が出来る。そこで柱を、アンカーのパイプに挿入して立て、蝶ボルトで絞めば動かなくなる。この柱は、「従来の技術」の項で例を示した如く、旗竿であれば旗立になり、柱を立てれば物干し台になり、傘の柄であればビーチパラソル立てにする事が出来るし、その他柱を立ててテントを張る事も出来る。
【００１２】
【発明の効果】
以上のように、本発明のアンカーは、ねじり平鋼を使用しているので、地面に捩じ込むと、容易に抜けないし、一方抜く時は鉄棒を差込んで回せば、簡単に抜く事が出来る特徴がある。その上製作が簡単なので安く出来、持ち運びが容易で、誰でも楽に使用する事が出来る特徴がある。

BACKGROUND OF THE INVENTION
The present invention relates to a pile that is used when a pile is driven into the ground and a rope is hooked on the pile, and a pole stand that is used when a column is raised on the ground.
[0002]
[Prior art]
First, in the case of a conventional pile, as shown in FIG. 3 (a), an iron rod with a ring at the top is driven into the ground, or as shown in FIG. Is screwed into the ground, a rope is hung on the wheel, and a tent is pulled.
[0003]
Next, as shown in Fig. 4 (a), the conventional pole stand is made of concrete with a hole in the center, placed on the ground, and a flag pole is set up in the hole, or a pillar is set up and dried. It is on the table. Since this concrete base is heavy, to make it easy to carry, make the same shape base with a plastic container and put water inside when you use it, or put an iron pipe on the iron plate as shown in Fig. 4 (b) A welded base is made, and an umbrella handle is inserted into it to make a beach umbrella stand.
[0004]
[Problems to be solved by the invention]
First, since the conventional bar-shaped pile is easy to come out and the spiral pile is expensive, the present invention is intended to provide a pile that is cheap and difficult to remove.
[0005]
Next, in the conventional column stand, the concrete base is heavy and difficult to carry, and it cannot be said that the plastic container stand and the iron stand are bulky and easy to carry. Therefore, the present invention intends to provide a column stand that is light and easy to carry.
[0006]
[Means for Solving the Problems]
Here, the present inventor has previously invented a method of twisting a flat steel bar with a uniform twist pitch everywhere and has been filed in Japanese Patent Application No. 9-12306. In the present invention, the twisted flat bar manufactured by this method is used as an anchor and screwed into the ground.
[0007]
First, as shown in Fig. 1 (a), the anchor to be used as a pile is a flat steel twisted hole. A hole through which a steel bar passes is formed at the top of the twisted flat bar, and the bar is inserted into the hole. If it is screwed into the ground and pulled through the rope through the hole, it will become a cheap and difficult to pull out pile.
[0008]
Next, as shown in Fig. 2, the anchor to be used as a column base is welded by connecting a pipe to a twisted flat bar, passing through a hole through which a steel bar passes, and inserting the bar into the hole. For example, twisted flat bars are easily screwed into the ground. In this case, if an iron rod is welded between the twisted flat bar and the pipe, it is not screwed any further, so that the position is determined and the pipe is prevented from being inclined. Since the pipe standing on the ground in this way is difficult to pull out and toppling over, it is only necessary to insert a pillar into the pipe. In this way, a column stand that is light and easy to carry can be obtained.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
First, the anchor to be used as a pile is shown in Fig. 1 (a) . Prepare a long torsion flat bar and an appropriately cut torsion flat bar (1), and make a hole (2) through which an iron bar passes near one end. Opening and sharpening the other tip a little so that it can easily get wet, it becomes an anchor that can be used instead of a conventional pile. Alternatively, as shown in Fig. 1 (b), prepare a twisted flat bar (1 ') with a little part of the flat bar and twist the tip of the flat bar. You may drill a little and sharpen the tip of the twisted flat bar. The anchor can be used by inserting a suitable iron bar into the hole and turning it so that it can be screwed into the ground and pulled through the hole through the rope.
[0010]
Then the anchor to be used as a pillar pin stand and shown in FIG. 2 as an actual施例, of approximately the same diameter as the width of the twisted flat bar prepared pipe (3), the width of the thickness of the flat steel the end of the pipe Make a cut. Then, the twisted flat bar (1 ′) shown in FIG. 1 (b) is inserted into this cut and welded, and the tip is sharpened slightly. Then, the hole (2) into which the iron bar is inserted passes through near the tip of the pipe, then another hole is opened in the vicinity thereof, and the nut (4) is welded to the hole to attach the butterfly bolt (5). Finally, if the iron plate is used to make a ridge (6) and weld it between the twisted flat bar and the pipe, it becomes an anchor that can be used in place of the conventional column stand.
[0011]
This anchor can be used by standing the anchor on the ground, inserting a suitable iron rod into the hole and turning it, and then the anchor can be screwed up to the saddle. So, if you insert the pillar into the anchor pipe and stand up and tighten it with a wing bolt, it will stop moving. This pillar can be used as a flag stand if it is a flagpole, as a clothesline if it is set up as a pole pole, or as a beach umbrella stand if it is an umbrella design However, you can also set up a tent with a pillar.
[0012]
【The invention's effect】
As described above, since the anchor of the present invention uses a twisted flat bar, it cannot be easily pulled out when screwed into the ground. On the other hand, it can be easily pulled out by inserting and turning a steel bar. There are features that can be done. In addition, since it is easy to manufacture, it is cheap, easy to carry, and anyone can use it easily.
