본 발명은 선박 또는 해양구조물에 사용되는 무관통 접지볼트에 관한 발명이다.The present invention relates to a non-penetrating ground bolt used in a ship or offshore structure.

먼저, 본 발명의 무관통 접지볼트는 머리부(100)와 몸체부(200), 드릴부(300)로 이루어진다.First, the non-penetrating ground bolt of the present invention is composed of a head portion 100, a body portion 200, and a drill portion 300.

이때, 머리부(100)와 몸체부(200), 드릴부(300)는 각각 별도로 형성되고, 머리부(100)는 일측에는 암나사부(120)가 형성된다.At this time, the head part 100, the body part 200, and the drill part 300 are formed separately, and the head part 100 has a female screw part 120 formed on one side thereof.

몸체부(200)은 접지부(210)와 기재 밀착부(220), 기재밀착 수나사부(230)로 이루어지며, 몸체부(200)의 중심을 관통하여 형성되는 관통부(240)가 형성된다.The body part 200 is composed of a ground part 210, a base material contact part 220, and a base material contact male screw part 230, and a through part 240 formed through the center of the body part 200 is formed. .

드릴부(300)는 수나사부(310)와 관통축부(320), 드릴 절삭날부(330)로 형성된다.The drill part 300 is formed of a male thread part 310, a through shaft part 320, and a drill cutting edge part 330.

드릴부(300)의 관통축부(320)가 몸체부(200)의 관통부(240)를 관통하고, 수나사부(310)가 머리부(100)의 암나사부(120)에 나사 체결되어 결합된다.The through-shaft part 320 of the drill part 300 passes through the through part 240 of the body part 200, and the male thread part 310 is screwed to the female thread part 120 of the head part 100 to be coupled. .

드릴부(300)의 관통축부(320)가 몸체부(200)의 관통부(240)를 관통하고, 수나사부(310)가 머리부(100)의 암나사부(120)에 나사 체결되어 일체로 결합하는 반면, 몸체부(200)는 드릴부(300)의 관통축부(320)에 밀착되어 끼움결합은 되나, 드릴부(300) 및 머리부와 일체로 체결되지 않으므로써, 토크렌치(미도시)등의 공지의 체결공구로 머리부(100)를 회전시키면 일체로 결합된 드릴부(300)의 드릴 절삭날부(330)가 기재를 절삭하며 파고들고, 일정깊이로 파고들게 되면, 몸체부(200)의 가재밀착 수나사부(230)가 관통된 구멍에 회전하며 안착되어 기재에 밀착되게 된다.The through-shaft part 320 of the drill part 300 passes through the through part 240 of the body part 200, and the male thread part 310 is screwed to the female thread part 120 of the head part 100 to be integrated. On the other hand, the body part 200 is in close contact with the through-shaft part 320 of the drill part 300 and is fitted, but it is not integrally fastened with the drill part 300 and the head, so that a torque wrench (not shown) When the head part 100 is rotated with a known fastening tool such as ), the drill cutting edge part 330 of the integrated drill part 300 cuts the base material and digs into it, and when it digs into a certain depth, the body part ( The crayfish close male screw portion 230 of 200) rotates and is seated in the through hole to be in close contact with the substrate.

이를 가능하게 하기 위해서는 드릴부(300)와 몸체부(200)의 회전속도가 달라야 하므로, 드릴부(300)와 몸체부(200)가 일체로 결합되어 동일한 회전속도로 회전하지 못하도록 각각 형성되어 밀착되도록 끼움 결합되므로써, 토크렌트 등으로 드릴부(300)와 머리부(100)를 기재에 밀착시키며 회전시키는 초기에는 몸체부(200)가 드릴부(300)의 관통축부(320)에 밀착되어 있으므로 거의 동일한 회전속도로 따라 회전하다가, 몸체부(200)의 기재밀착 수나사부(230)가 기재에 접촉되면서부터 드릴부(300)의 회전속도보다 줄어들게 되고, 기재밀착 수나사부(230)가 기재에 회전하며 파고들어 안착하여 기재와 결합하게 된다.In order to enable this, since the rotational speed of the drill part 300 and the body part 200 must be different, the drill part 300 and the body part 200 are integrally combined to prevent rotation at the same rotational speed. Since the body part 200 is in close contact with the through-shaft part 320 of the drill part 300 at the initial stage of rotation while the drill part 300 and the head part 100 are in close contact with the substrate by using a torque rental, etc. While rotating at approximately the same rotational speed, the rotational speed of the drill part 300 decreases as the base material-contacting male screw part 230 of the body part 200 comes into contact with the base material, and the base material-contacting male screw part 230 is applied to the base material. It rotates and digs into place to settle and bond with the substrate.

드릴부(300)와 머리부(100)를 토크렌치 등으로 1차적으로 회전하여 기재밀착 수나사부(230)이 안착되는 통공을 형성한 후, 기재밀착 수나사부(230)를 2차적으로 토크렌치 등으로 회전시켜 몸체부(200)가 기재에 더욱 밀착될 수 있도록 하기 위하여 몸체부(200)의 기재 밀착부(220)의 평면형상은 토크렌치의 소켓의 형상에 따라 다각형 등의 형상으로 형성될 수 도 있다.After the drill part 300 and the head part 100 are first rotated with a torque wrench, etc. to form a through hole in which the base material-contacting male screw part 230 is seated, the base-contacting male screw part 230 is secondarily tightened with a torque wrench. The planar shape of the base material contact part 220 of the body part 200 may be formed in a polygonal shape according to the shape of the socket of the torque wrench in order to rotate the body part 200 so that the body part 200 can be more closely attached to the base material. You can also.

선박, 해양구조물 등에 시공되는 접지볼트는 기재와 충분히 밀착되어 충분한 접지효과가 발현되면 되므로, 접지볼트의 결착강도는 외부 충격에 의해 기재로부터 탈락되는 것만 방지되는 정도로 충분하므로, 이 출원 발명의 몸체부에 형성된 기재 밀착 수나사부(230)가 드릴부(300)의 회전속도보다 줄어들어 충분히 밀착되는 정도로 접지 효과는 충분히 얻을 수 있는 것이다.Ground bolts installed in ships, offshore structures, etc. need to be sufficiently in close contact with the substrate to exhibit sufficient grounding effect, so that the bonding strength of the ground bolts is sufficient to prevent it from falling off from the substrate by external impact. The grounding effect can be sufficiently obtained so that the male screw portion 230 in contact with the substrate formed in is reduced than the rotational speed of the drill portion 300 and is sufficiently in close contact.

이때, 드릴부(300)가 파고드는 일정깊이가 깊어지면 기재에 균열이 일어날 가능성이 증가하므로, 드릴부(300)가 파고드는 일정깊이는 기재의 70%를 초과하지 않도록 드릴부(300)의 드릴 절삭날부(330)로부터 몸체부(200)의 기재 밀착부(220)까지의 길이는 기재의 70%를 초과하지 않도록 형성되는 것이 바람직하다.At this time, since the possibility of cracking in the base material increases when a certain depth in which the drill part 300 digs deepens, the certain depth in which the drill part 300 digs does not exceed 70% of the base material. It is preferable that the length from the drill cutting edge portion 330 to the substrate contact portion 220 of the body portion 200 is formed so as not to exceed 70% of the substrate.

실제로 이 출원 발명의 무관통 접지볼트를 선박의 기재에 시공했을 때, 몸체부(200)가 드릴부(300)의 관통축부(320)에 끼움되어 기재에 충분히 밀착되기 위해서는, 도면 3 및 4와 같이 관통축부(320)의 길이가 몸체부의 길이보다 길게 형성되는 것이 바람직하고, 그 길이는 2~4mm 정도 일 때, 구체적으로는 약 4mm 일 때, 충분한 결착강도를 얻을 수 있었다.In fact, when the non-penetrating ground bolt of the present invention is installed on the substrate of the vessel, the body portion 200 is fitted into the through shaft portion 320 of the drill portion 300 to sufficiently adhere to the substrate, as shown in FIGS. 3 and 4 As such, it is preferable that the length of the through shaft part 320 is formed longer than the length of the body part, and when the length is about 2 to 4 mm, specifically about 4 mm, sufficient binding strength could be obtained.

몸체부(200)의 기재밀착 수나사부(230)의 길이 역시 너무 길면 기재를 파고들어 안착되는 시공성능이 떨어지므로, 그 길이가 2~4mm 정도 일 때, 구체적으로는 약 4mm 일 때, 시공성능 및 결착강도가 제일 높았다.If the length of the male screw part 230 that adheres to the base material of the body part 200 is also too long, the construction performance to penetrate and settle the base material decreases, so when the length is about 2 to 4 mm, specifically about 4 mm, the construction performance And binding strength were the highest.

이러한 수치는 몸체부(200)와 머리부(100)와 드릴부(300)의 재질에 따라서도 영향을 받으며, 드릴부(300)는 재질의 경도가 낮아지면, 재질의 무름도가 커져 기재를 파고드는 드릴 성능이 떨어지므로, 드릴부(300)의 경도는 몸체부의 경도와 같거나 그보다 높은 재질로 형성되는 것이 바람직하다.These values are also affected by the material of the body part 200, the head part 100, and the drill part 300, and when the hardness of the material of the drill part 300 decreases, the softness of the material increases and Since the drilling performance is poor, it is preferable that the hardness of the drill part 300 is formed of a material equal to or higher than the hardness of the body part.

결착강도를 향상시키고, 몸체부(200)가 체결된 방향과 반대방향으로 풀리는 것을 방지하기 위하여 몸체부(200)의 기재밀착 수나사부(230)에는 나사산의 일측에 일방향 걸림돌기(231)를 형성할 수도 있다.In order to improve the bonding strength and prevent the body part 200 from being loosened in the direction opposite to the fastened direction, a one-way locking protrusion 231 is formed on one side of the screw thread in the male screw part 230 that adheres to the base material of the body part 200 You may.

아울러, 선박 및 해양구조물의 사용환경을 고려하여, 습기 등이 접촉되는 것을 방지하기 위하여 몸체부(200)의 기재 밀착부(220)와 기재 사이의 수밀패킹 안착부(250)에 수밀패킹이 구비되거나(미도시), 접지볼트를 시공한 후에 머리부(100)와 몸체부(200)의 접지부(210)를 덮는 실리콘 캡을 구비할 수도 있다(미도시).In addition, in consideration of the use environment of ships and offshore structures, a watertight packing is provided in the watertight packing seating part 250 between the base material contact part 220 of the body part 200 and the base material to prevent contact with moisture, etc. Alternatively, a silicon cap may be provided to cover the ground portion 210 of the head portion 100 and the body portion 200 after the ground bolt is installed (not shown).
