Description

견고한 결합이 가능한 앵커볼트{Anchor bolt}Anchor bolts for tight coupling {Anchor bolt}

본 발명은 견고한 결합이 가능한 앵커볼트에 관한 것으로, 더욱 상세하게는 콘크리트 벽체나 바닥, 천장 등에 매설한 앵커볼트가 쉬 흔들리거나 빠지지 않도록 하여 상기 앵커볼트에 결합된 부착물이 안정적인 상태를 유지할 수 있도록 하기 위한 앵커볼트에 관한 것이다.The present invention relates to an anchor bolt that can be firmly coupled, and more particularly, to prevent anchor bolts embedded in concrete walls, floors, ceilings, etc. from being easily shaken or dropped so that attachments coupled to the anchor bolts can be maintained in a stable state. It relates to an anchor bolt for.

일반적으로 앵커볼트는 못이나 볼트 등 기타 체결수단들을 설치하기 곤란한 콘크리트 구조물 등에 부착물을 결합하기 위해 설치하는 것으로, 콘크리트 구조물에 구멍을 천공하고 상기 구멍에 원추형의 쐐기부와 나사부를 구비하는 볼트와, 절개부 사이에 확관부(擴管部)를 구비하는 확관파이프를 집어넣고 상기 확관파이프를 타격수단으로 밀어넣어 상기 확관부가 볼트의 쐐기부에 의해 확관, 즉 방사상으로 벌어지면서 콘크리트 구멍 속에 꽉 끼어 결합되도록 한다.In general, anchor bolts are installed to couple attachments to concrete structures, such as nails and bolts, which are difficult to install. Bolting holes in concrete structures and having conical wedges and threads in the holes, Insert an expansion pipe having an expansion pipe portion between the incisions and push the expansion pipe into the striking means so that the expansion pipe is secured into the concrete hole by expanding it radially by the wedge of the bolt. To be combined.

이때 볼트의 나사부만 콘크리트 구조물로부터 돌출되며, 상기 나사부에 부착물, 즉 형강, 빔(Beam), 캐링채널(Carrying channel), 브래킷(Bracket), 파이프, 와이어, 케이블 등이 결합되어 진다.At this time, only the threaded portion of the bolt protrudes from the concrete structure, and the attachment portion, that is, the beam, the beam, the carrying channel, the bracket, the pipe, the wire, the cable, and the like are coupled to the screwed portion.

따라서 앵커볼트와 콘크리트 구조물의 결합력에 의해 부착물의 안정적인 설치 여부가 결정되어 지는 것이어서, 보다 견고한 앵커볼트와 콘크리트 구조물 사이의 결합을 강화하기 위한 노력들이 진행되고 있다.Therefore, whether or not the stable installation of the attachment is determined by the coupling force of the anchor bolt and the concrete structure, efforts are being made to strengthen the coupling between the more secure anchor bolt and the concrete structure.

그러나 상기한 종래의 앵커볼트(1)는 [도 1]에 도시한 바와 같이 확관파이프의 일측, 즉 확관부만 볼트의 쐐기부에 의해 벌어지면서 쐐기부와 콘크리트 구멍 사이에 꼭 낀 상태로 앵커볼트가 빠지지 않도록 한다.However, the above-mentioned conventional anchor bolt 1 is anchored in a state sandwiched between the wedge portion and the concrete hole while the one side of the expansion pipe, that is, only the expansion pipe is opened by the wedge of the bolt as shown in FIG. Does not fall out.

그러나 이처럼 결합된 종래의 앵커볼트(1)는 확관부의 끝부분만 콘크리트 구멍에 박혀있는 상태여서 다른 부분은 콘크리트 구멍과의 이격에 의해 앵커볼트(1)를 잡고 흔들면 상하좌우로 흔들리게 된다.However, the conventional anchor bolt (1) coupled in this way is only the end of the expansion portion is embedded in the concrete hole so that the other part is shaken up, down, left and right when holding the anchor bolt (1) by the separation from the concrete hole.

또한, 앵커볼트(1) 중 한 지점만 콘크리트 구멍과 밀착된 구조여서 견고한 결합상태를 유지하지 못하는 단점을 갖는다.In addition, only one point of the anchor bolt (1) has a disadvantage in that the structure is in close contact with the concrete hole does not maintain a firm coupling state.

이처럼 불안정한 결합상태를 갖는 앵커볼트는 결국 불안정한 구조물의 부착으로 이어져 부착물의 낙하로 인한 사고의 우려가 높은 단점을 갖는 것이다.The anchor bolt having such an unstable coupling state has the disadvantage that there is a high risk of an accident due to the drop of the attachment, which eventually leads to the attachment of the unstable structure.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로, 본 발명은 앵커볼트가 콘크리트 구멍 속에 결합되도록 하되 앵커볼트의 확관부가 적어도 두 곳 이상 콘크리트 구멍 내측면에 밀착되도록 하고, 또 앵커볼트가 콘크리트 구멍 내측면에 박혀 쉬 이탈되지 않도록 하고, 콘크리트 구멍 속에서 흔들리거나 놀지 않도록 함으로써 부착물의 견고한 결합을 가능하게 함을 목적으로 한다.Therefore, the present invention was devised to solve the above problems, the present invention is to allow the anchor bolt is coupled in the concrete hole, but the expansion portion of the anchor bolt to be in close contact with the inner surface of the concrete hole at least two, and the anchor bolt Is to be embedded in the inner surface of the concrete hole so that it is not easily separated, and not to shake or play in the concrete hole, thereby enabling a firm coupling of the attachment.

이처럼 본 발명은 앵커볼트가 콘크리트 구멍 속에 결합 됨에 있어 앵커볼트 세 부분이 콘크리트 구멍 내측면에 밀착되어 앵커볼트가 콘크리트 구멍 속에서 흔들리거나 놀지 않게 되어 부착물의 견고한 결합을 가능하게 하는 효과를 갖는다.Thus, in the present invention, the anchor bolt is coupled in the concrete hole, the three parts of the anchor bolt is in close contact with the inner surface of the concrete hole has the effect that the anchor bolt does not shake or play in the concrete hole to enable a firm coupling of the attachment.

또한 본 발명은 앵커볼트의 뾰쪽한 경사돌기가 콘크리트 구멍 내측면에 이탈방향과 반대방향으로 박히는 구조여서 박혀 앵커볼트가 콘크리트 구멍으로부터 쉬 이탈되지 못하도록 하는 매우 유용한 발명인 것이다.In addition, the present invention is a very useful invention to prevent the anchor bolt from being easily separated from the concrete hole because the inclined protrusion of the anchor bolt is embedded in the concrete hole in the opposite direction to the separation direction.

이하 첨부된 도면에 의해 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

상기 결합보강부재(120)는 절개홈(124)를 구비하는 원통부(121)와, 상기 원통부(121)의 일측에 전방으로 연장되는 2~4개의 연장부(122)와, 상기 연장부(122)의 끝단에 형성된 경사돌기(123)로 구성되어 진다.The coupling reinforcing member 120 is a cylindrical portion 121 having a cutting groove 124, two to four extension portions 122 extending forward in one side of the cylindrical portion 121, and the extension portion It is composed of the inclined protrusion 123 formed at the end of the (122).

상기 연장부(122)는 확관파이프(130)가 작업자의 타격에 의해 후방, 즉 볼트(110)의 쐐기부(112)를 향해 밀릴 때 원통부(121)도 따라서 밀리도록 하기 위한 구성으로, 이를 가능하게 하기 위해 상기 연장부(122)의 끝단은 확관파이프(130)의 통공(131) 가장자리와 맞닿는 구조를 갖는다. 즉 연장부(122)의 끝단과 통공(131)의 가장자리의 높이는 일치되도록 함으로써 확관파이프(130)가 밀릴 때 결합보강부재(120)도 밀리도록 구성되어 진다.The extension portion 122 is configured to push the cylindrical portion 121 along the back when the expansion pipe 130 is pushed toward the wedge portion 112 of the bolt 110, that is, by the impact of the worker, this In order to enable the end portion of the extension 122 has a structure that abuts the edge of the through-hole 131 of the expansion pipe 130. That is, the height of the end of the extension portion 122 and the edge of the through hole 131 is matched so that the coupling reinforcing member 120 is pushed when the expansion pipe 130 is pushed.

따라서 결국 상기 결합보강부재(120)의 원통부(121) 역시 쐐기부(112)의 경사면을 타고 오르며 찢어지면서 확관, 즉 방사형으로 벌어지게 되고, 이로 인해 확관파이프(130)의 확관부(133) 중간 부분을 밀어올리면서 콘크리트 구멍 내측면에 밀착되도록 한다.Accordingly, the cylindrical portion 121 of the coupling reinforcing member 120 also rises and tears along the inclined surface of the wedge portion 112 and is widened in a radial manner, that is, the expansion portion 133 of the expansion pipe 130. While pushing up the middle part, it is pressed against the inner surface of the concrete hole.

이처럼 본 발명 앵커볼트(100)는 확관파이프(130)의 확관부(133)가 벌어지면서 끝 부분이 콘크리트 구멍 내측면에 밀착되어 지고, 결합보강부재(120)의 원통부(121)가 확관부(133) 중간 부분을 밀어올리면서 콘크리트 구멍 내측면에 밀착되는 구성이어서 종래 한 지점만 고정되던 기존 앵커볼트(1)에 비해 보다 안정적인 부착물의 고정이 가능한 것이다.As described above, the anchor bolt 100 of the present invention is the expansion portion 133 of the expansion pipe 130, the end portion is in close contact with the inner surface of the concrete hole, the cylindrical portion 121 of the coupling reinforcing member 120 is expanded portion (133) It is a configuration that is in close contact with the inner surface of the concrete hole while pushing up the middle portion, it is possible to fix the more stable attachment than the conventional anchor bolt (1) that was fixed only one point in the prior art.

더구나 본 발명 앵커볼트(100)는 확관파이프(130)의 통공(131) 가장자리 일측에 경사부(131a)를 형성하고, 결합보강부재(120)의 연장부(122) 끝단에는 외측으로 벌어진 구조의 경사돌기(123)를 형성함으로써 확관파이프(130)가 후방으로 밀릴 때 상기 경사돌기(123)가 경사부(131a)에 의해 방사형으로 벌어짐과 동시에 타고 들어올려지도록 구성함으로써 뾰쪽한 형상의 경사돌기(123)가 콘크리트 구멍의 내측면에 박힘과 동시에 밀착되어져 견고한 결합이 가능해진다.Moreover, the anchor bolt 100 of the present invention forms an inclined portion 131a at one side of the edge of the through-hole 131 of the expansion pipe 130, and the extension portion 122 of the coupling reinforcing member 120 is formed to be outward. When the expansion pipe 130 is pushed backward by forming the inclined protrusion 123, the inclined protrusion 123 is radially opened by the inclined portion 131a, and is configured to be lifted up at the same time so that the inclined protrusion (123) 123 is pushed into the inner surface of the concrete hole and at the same time tightly contacted to enable a firm coupling.

상기 경사돌기(123)는 확관파이프(130)의 절개부(132)에 의해 안내되어져 통공(131)의 중간부에 위치하게 된다.The inclined protrusion 123 is guided by the cutout 132 of the expansion pipe 130 to be positioned in the middle of the through hole 131.

이처럼 본 발명은 비록 한정된 실시예에 의해 설명되었으나, 본 발명은 이것에 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.As described above, the present invention has been described by means of a limited embodiment, but the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains to the technical spirit of the present invention and claims to be described below.
