【考案の詳細な説明】[Detailed description of the invention]

【0001】[0001]

【考案の属する技術分野】[Technical field to which the invention belongs]

本考案はアース棒の改良構造に関するもので、とくに構造が単純で、操作が簡 便であり、銅皮管が破損するという問題を改良し、円錐形のヘッドを取り付けら れるという長所を持ち、生産コストを低減し、経済および実用効率を向上したも のを指す。 The present invention relates to an improved structure of the earth rod, which has the advantages that the structure is simple, the operation is simple, the problem of the copper skin tube being damaged is improved, and a conical head can be attached. It refers to products that have reduced production costs and improved economic and practical efficiency.

【0002】[0002]

【従来の技術】[Prior art]

従来のアース棒は1つの銅皮管2で覆われ、表面が磨かれたスチール棒1であ り、当該スチール棒2の前端は円錐形を呈し(図1を参照)、スチール棒1を直 接地中に打ち込むことができる。地質は砂土、花崗岩、石灰岩など多くの種類が あり、スチール棒1を固い地質に打ち込むと、スチール棒を覆う銅皮管2と地質 の間で抵抗力が発生し、銅皮管2が捲縮しやすく(図2を参照)、銅皮管2の誘 電効果を十分に発揮することができない。 A conventional earthing rod is a steel rod 1 covered with a single copper sheath tube 2 and having a polished surface. The front end of the steel rod 2 has a conical shape (see FIG. 1), and the steel rod 1 is straightened. Can be driven into the ground. There are many types of geology, such as sandy soil, granite, and limestone. When the steel rod 1 is driven into hard geology, resistance occurs between the copper sheath 2 covering the steel bar and the geology, and the copper sheath 2 is wound. It is easy to shrink (see FIG. 2), and the effect of inducing the copper sheath tube 2 cannot be sufficiently exhibited.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the invention]

本考案の主な目的は、従来のアース棒はアース効果を完全に発揮することがで きず、コストも高く、不便であるため、本考案では操作が簡単で、正確且つ簡単 に地中に埋め込むことができ、銅皮管が破損しにくく、アース効果を十分に発揮 できるアース棒を開発することである。 もう1つの目的は、スチール棒の先端にある円錐状ヘッドを取り外しできるよ うに設計して、加工操作を簡素化し、経済効果を高めることである。 The main purpose of the present invention is that the conventional earthing rod cannot fully exhibit the earthing effect, is expensive, and is inconvenient. The purpose is to develop an earth rod that can make the copper skin tube less susceptible to damage and exhibit a sufficient earth effect. Another objective is to design the conical head at the end of the steel bar so that it can be removed, simplifying the machining operation and increasing economic efficiency.

【0005】[0005]

【考案の実施の形態】[Embodiment of the invention]

図3に示す通り、本考案のアース棒におけるスチール棒1は表面に網状溝、交 叉溝、又はその他の形状を呈する溝11を有する。且つスチール棒1の一端には 円錐状ヘッド12があり、当該円錐状ヘッドの最大直径はスチール棒1を覆う銅 皮管の直径より大きい。 図4に示す通り、本考案のアース棒は、スチール棒1を先ず銅皮管2に嵌入す る。当該銅皮管2は延伸することで直径を小さくすることができる。スチール棒 上で銅皮管2を延伸し、銅皮管2の内径の一部がスチール棒1の溝11に深く入 り込むようにして、銅皮管2とスチール棒1を堅牢に付着させる(図5、図6を 参照)。 本考案のアース棒は、銅皮管2がスチール棒1外部に堅牢に付着しているため 、スチール棒を地中に打ち込む際に銅皮管2が破損して脱落したり、捲縮すると いう問題が発生しない。当該スチール棒1の円錐状ヘッド12は銅皮管2の外径 より大きいため、スチール棒1を地中に埋設するとき、銅皮管2と地表の摩擦は 発生しない。このため、銅皮管が破損して脱落したり、捲縮することはない。 本考案ではアース棒の製造を簡素化し、コストを低減するため、スチール棒1 と円錐状ヘッド12をそれぞれ作製し、最後に組み合わせる。図7と図8に示す 通り、スチール棒1の前端には、円錐状ヘッド12の傾斜度を持つ内孔121に 嵌入できる嵌入部分13がある。嵌入部分13の傾斜度も内孔121の内径と密 着するようサイズを設計する(ここではモース・テーパー(MORSE TAPER) の原理 を採用)。これにより、アース棒を地中に打ち込む際、嵌入部分13と内孔12 1は緊密に接触し、円錐状ヘッド12が移動したり、脱落する問題が発生しない 。 円錐状ヘッド12の最大直径は少なくともアース棒の外径より大きく、銅皮管 2の前端21が円錐状ヘッド12の端面122に入り込むため、従来のアース棒 の銅皮管前端が直接地面と接触し、捲縮するという問題は発生しない。これによ りアース棒の寿命を延ばすことができる。 このほか、スチール棒1と円錐状ヘッド12の固定を図9、図10のように設 計することもできる。つまり、スチール棒1の前端にねじ棒111を設置し、当 該ねじ棒111を円錐状ヘッド12内のねじ孔123にねじ入れるよう設計する 。この時も当該円錐状ヘッド12の最大直径を、スチール棒1を覆う銅皮管2の 外径より大きく設計する。 As shown in FIG. 3, the steel rod 1 in the ground rod of the present invention has a groove 11 having a net-like groove, a cross groove, or another shape on its surface. And at one end of the steel rod 1 there is a conical head 12 whose maximum diameter is larger than the diameter of the copper sheath covering the steel rod 1. As shown in FIG. 4, in the earth rod of the present invention, a steel rod 1 is first fitted into a copper sheath tube 2. The copper sheath tube 2 can be reduced in diameter by stretching. The copper skin tube 2 is stretched on the steel bar, and a part of the inner diameter of the copper skin tube 2 is inserted deeply into the groove 11 of the steel bar 1, so that the copper skin tube 2 and the steel bar 1 are firmly attached (see FIG. 5, see Figure 6). In the ground rod of the present invention, since the copper sheath tube 2 is firmly attached to the outside of the steel bar 1, when the steel bar is driven into the ground, the copper sheath tube 2 is damaged and falls off or is crimped. No problem. Since the conical head 12 of the steel rod 1 is larger than the outer diameter of the copper pipe 2, when the steel rod 1 is buried in the ground, no friction occurs between the copper pipe 2 and the ground. Therefore, the copper skin tube is not broken and falls off or crimped. In the present invention, the steel rod 1 and the conical head 12 are separately manufactured and finally combined to simplify the manufacturing of the ground rod and reduce the cost. As shown in FIGS. 7 and 8, at the front end of the steel bar 1, there is a fitting portion 13 that can be fitted into the inclined inner hole 121 of the conical head 12. The size of the fitting portion 13 is designed so that the inclination of the fitting portion 13 is also close to the inner diameter of the inner hole 121 (here, the principle of the Morse taper is adopted). Thus, when the ground rod is driven into the ground, the fitting portion 13 and the inner hole 121 are in close contact with each other, and there is no problem that the conical head 12 moves or falls off. The maximum diameter of the conical head 12 is at least larger than the outer diameter of the earth rod, and the front end 21 of the copper sheath tube 2 enters the end face 122 of the conical head 12, so that the front end of the copper sheath tube of the conventional earth rod directly contacts the ground. However, the problem of crimping does not occur. This can extend the life of the earth rod. In addition, the fixing of the steel bar 1 and the conical head 12 can be designed as shown in FIGS. That is, the screw rod 111 is installed at the front end of the steel rod 1, and the screw rod 111 is designed to be screwed into the screw hole 123 in the conical head 12. At this time, the maximum diameter of the conical head 12 is designed to be larger than the outer diameter of the copper sheath tube 2 covering the steel rod 1.

【考案の効果】[Effect of the invention]

本考案のアース棒は、スチール棒1の表面に溝11を有し、銅皮管2との密着 を高めるほか、円錐状ヘッド12とスチール棒1を分離することで、生産コスト を低減でき、地質により円錐状ヘッドの材質(金属やその他固い材料)を変更す ることができ、経済効果と実用性を向上することができる。 The earth rod of the present invention has a groove 11 on the surface of the steel rod 1 to increase the adhesion to the copper sheath tube 2 and to reduce the production cost by separating the conical head 12 and the steel rod 1. The material (metal or other hard material) of the conical head can be changed depending on the geology, and the economic effect and practicality can be improved.
