본 발명은 앵커볼트 결합용 슬리브관의 구조에 관한 것으로서, 더욱 상세하게는 벽이나 천장에 뚫려진 구멍에 끼워진 원통형 슬리브관의 내부 상측에는 요철부가 형성되고 슬리브관의 상부에 결합되는 원추형 쐐기에도 요철부가 형성되어 쐐기가 슬리브관에 결합되었을 때 요철부들의 마찰력에 의하여 쐐기의 이탈이 방지됨에 따라 슬리브관이 구멍에서 이탈되지 않도록 하여 작업장의 안전사고를 미연에 방지할 수 있도록 한 발명에 관한 것이다.The present invention relates to a structure of an anchor bolt coupling sleeve tube, and more particularly, an uneven portion is formed on an inner upper side of a cylindrical sleeve tube inserted into a hole drilled in a wall or a ceiling, and a concave-shaped wedge is coupled to an upper portion of the sleeve tube. When the wedge is formed is coupled to the sleeve tube and the wedge is prevented from being separated by the frictional force of the uneven portion relates to the invention to prevent the safety accident of the workplace in advance by preventing the sleeve tube from being separated from the hole.

일반적으로 PC 강선의 상부에 나선부가 형성된 앵커볼트를 벽이나 천장에 고정시켜 각종 구조물이 매달을 수 있도록 하는 어스앵커공법(Earth-Anchor Method)은 주로 슬리브관을 천장에 뚫려진 구멍에 삽입하여 모르타르로 그라우팅하여 굳힌 다음 슬리브관의 하부에 앵커볼트를 나사 결합하여 사용할 수 있도록 구성되어 있다.In general, the Earth-Anchor Method, which fixes the anchor bolts formed with a spiral part on the upper part of the PC steel wire to the wall or the ceiling, to allow various structures to be suspended, mainly inserts the sleeve tube into the hole drilled in the ceiling and then mortar. It is configured to be used by screwing the anchor bolt in the lower part of the sleeve after hardening by grouting.

근래에는 슬리브관을 모르타르로 그라우팅하여 굳히지 않고, 도 1에서 도시한 바와 같이 절취홈(12)이 형성된 슬리브관(10)의 상부에 원추형 쐐기(20)를 끼운 다음 슬리브관(10)의 하부를 타격하면 테이퍼형 쐐기(20)에 의하여 슬리브관(10)의 상부가 절취홈(12)을 따라 벌어지면서 구멍에 밀착되어 슬리브관(10)이 구멍의 내부에 고정되는 공법을 주로 사용하였다.Recently, the sleeve tube is not hardened by grouting with a mortar, and as shown in FIG. 1, the conical wedge 20 is inserted into the upper portion of the sleeve tube 10 having the cut groove 12 formed therein, and then the lower portion of the sleeve tube 10. When hitting the upper portion of the sleeve tube 10 by the tapered wedge 20 along the cutting groove 12 is in close contact with the hole was used mainly the method in which the sleeve tube 10 is fixed to the inside of the hole.

그러나, 전술한 바와 같이 원추형 쐐기(20)를 이용하여 슬리브관(10)의 상부를 확장시키는 경우에는 슬리브관(10)과 쐐기(20) 사이에 마찰력이 약하기 때문에 앵커볼트(30)에 매달린 구조물의 중량이 무겁거나 앵커볼트(30)에 구조물을 장착하는 과정에서 사소한 충격이라도 발생되면 쐐기(20)가 슬리브관(10)에서 이탈됨과 동시에 슬리브관(10)이 구멍에서 이탈되면서 구조물과 함께 낙하되는 등의 폐단이 발생되었다.However, when the upper portion of the sleeve tube 10 is expanded by using the conical wedge 20 as described above, because the friction force between the sleeve tube 10 and the wedge 20 is weak, the structure suspended on the anchor bolt 30 If the weight of the heavy or even a slight impact occurs in the process of mounting the structure to the anchor bolt 30, the wedge 20 is released from the sleeve tube 10 and at the same time the sleeve tube 10 is separated from the hole and falls with the structure Such as discontinuation occurred.

이와 같이 슬리브관(10)이 구멍에서 이탈되면서 구조물이 낙하되는 경우에는 작업의 효율이 현저하게 저하되었을 뿐 아니라 작업자들이 안전사고를 당하는 등의 문제점이 발생되었으므로 강한 충격에서도 쐐기(20)가 이탈되지 않고 구조물의 하중을 안정적으로 지탱할 수 있는 견고한 구조를 갖는 슬리브관(10)의 제안이 절실히 요구되었다.In this way, when the sleeve tube 10 is separated from the hole and the structure falls, not only the work efficiency is significantly lowered, but also the workers are in a safety accident, so that the wedge 20 is not separated even in a strong impact. There is an urgent need for a proposal of a sleeve tube 10 having a rigid structure capable of stably supporting a load of a structure without the need.

본 발명은 상기한 문제점을 감안하여 창안한 것으로서, 그 목적은 천장에 뚫려진 구멍에 끼워진 원통형 슬리브관의 내부 상측에 쐐기가 결합되었을 때 요철부들의 마찰력에 의하여 쐐기의 이탈이 방지됨에 따라 슬리브관이 구멍에서 이탈되지 않도록 하여 작업장의 안전사고를 미연에 방지할 수 있는 앵커볼트 결합용 슬리브관의 구조를 제공함에 있는 것이다.The present invention has been made in view of the above-mentioned problems, and its object is that the sleeve is prevented from being detached from the wedge by the frictional force of the uneven portions when the wedge is coupled to the inner upper side of the cylindrical sleeve tube inserted into the hole drilled in the ceiling. It is to provide a structure of the anchor bolt coupling sleeve tube that can prevent the safety accident of the workplace in advance to prevent the deviation from this hole.

상기한 목적을 달성하기 위한 본 발명의 특징은, 벽이나 천장에 뚫려진 구멍(1)에 끼워지는 원통형 슬리브관(10)의 상부에는 절취홈(12)이 형성되어 슬리브 관(10)의 상부에 결합되는 원추형 쐐기(20)에 의하여 슬리브관(10)의 상부가 절취홈(12)을 따라 벌어지면서 구멍(1)에 밀착되어 고정되고, 슬리브관(10)의 내부 하측에는 나선부(13)가 형성되어 앵커볼트(30)의 상부 나선부(31)가 나사 결합되는 구조의 슬리브관에 있어서, 상기 슬리브관(10)의 내부 상측에는 요철부(11)가 형성되고, 쐐기(20)의 외주면에도 요철부(21)가 형성되어 슬리브관(10)에 쐐기(20)가 결합되면 요철부(11)(21)들의 마찰력에 의하여 쐐기(20)가 슬리브관(10)에서 이탈되지 않도록 한 것을 특징으로 하는 앵커볼트 결합용 슬리브관의 구조에 의하여 달성될 수 있는 것이다.Features of the present invention for achieving the above object, the upper portion of the sleeve sleeve 10 is formed with a cutting groove 12 is formed in the upper portion of the cylindrical sleeve tube 10 fitted in the hole 1 drilled in the wall or ceiling An upper portion of the sleeve tube 10 is fixed to the hole 1 by being squeezed along the cutout groove 12 by a conical wedge 20 coupled to the spiral portion 13. In the sleeve tube having a structure in which the upper spiral portion 31 of the anchor bolt 30 is screwed, the uneven portion 11 is formed on the inner upper side of the sleeve tube 10, the wedge 20 Uneven portion 21 is also formed on the outer circumferential surface of the wedge 20 is coupled to the sleeve tube 10 so that the wedge 20 is not separated from the sleeve tube 10 by the frictional force of the uneven portion (11) (21) What can be achieved by the structure of the anchor bolt coupling sleeve tube characterized in that one.

이하, 상기한 목적을 달성하기 위한 바람직한 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

도 2 내지는 도 4에서 도시한 바와 같이, 벽이나 천장에 뚫려진 구멍(1)에는 원통형 슬리브관(10)이 끼워져 있고, 슬리브관(10)의 상부에는 사방으로 트여진 절취홈(12)이 형성되어 있다.2 to 4, a cylindrical sleeve tube 10 is fitted into the hole 1 drilled in the wall or ceiling, and a cutout groove 12 extending in all directions is formed in the upper portion of the sleeve tube 10. As shown in FIG. Formed.

상기 슬리브관(10)의 상부에는 역 사다리꼴을 이루는 원추형 쐐기(20)가 결합되어 있고, 구멍(1)의 하부로 돌출되는 슬리브관(10)을 타격하면 원추형 쐐기(20)에 의하여 슬리브관(10)의 상부가 절취홈(12)을 따라 외측으로 벌어지면서 구멍(1)에 밀착되어 견고하게 고정된다.An upper trapezoidal cone shaped wedge 20 is coupled to the upper portion of the sleeve tube 10, and when hitting the sleeve tube 10 protruding to the lower portion of the hole 1, the sleeve tube 10 is formed by the conical wedge 20. The upper part of 10) is tightly fixed to the hole 1 while being opened outward along the cutting groove 12.

상기 슬리브관(10)의 내부 하측에는 나선부(13)가 형성되어 있고, 나선부 (13)에는 앵커볼트(30)의 상부에 형성된 나선부(31)가 나사 결합되어 앵커볼트(30)의 하부에 각종 구조물(40)을 장착하여 매달려지도록 할 수 있는 것이다.The spiral portion 13 is formed on the inner lower side of the sleeve tube 10, and the spiral portion 31 formed on the upper portion of the anchor bolt 30 is screwed to the spiral portion 13 to form the anchor bolt 30. The various structures 40 can be mounted on the lower side to be suspended.

물론, 전술한 구조로 이루어진 슬리브관(10)은 이미 알려진 공지의 기술사상이다. 그러나, 본 발명에 있어서 가장 중요한 특징은 상기 슬리브관(10)과 쐐기(20)에 요철부(11)(21)들이 각각 형성되어 마찰력을 최대한 높여줄 수 있도록 한 것에 있다.Of course, the sleeve tube 10 having the above-described structure is a known art. However, the most important feature in the present invention is that the uneven parts 11 and 21 are formed in the sleeve tube 10 and the wedge 20 so as to increase the friction force as much as possible.

즉, 상기 슬리브관(10)의 내부 상측에는 요철부(11)가 형성되어 있고, 쐐기(20)의 외주면에도 요철부(21)가 형성되어 있다.That is, the uneven portion 11 is formed on the inner upper side of the sleeve tube 10, and the uneven portion 21 is formed on the outer circumferential surface of the wedge 20.

따라서, 슬리브관(10)의 상부에 역 사다리꼴을 이루는 원추형 쐐기(20)를 삽입하여 구멍(1)의 하부로 돌출되는 슬리브관(10)을 타격하면 원추형 쐐기(20)에 의하여 슬리브관(10)의 상부가 절취홈(12)을 따라 외측으로 벌어지면서 구멍(1)에 밀착되어 견고하게 고정된다.Therefore, inserting a conical wedge 20 forming an inverted trapezoid on the upper portion of the sleeve tube 10 and hitting the sleeve tube 10 protruding to the lower portion of the hole 1, the sleeve tube 10 by the conical wedge 20 The top of the) is opened to the outside along the cutting groove 12 to be in close contact with the hole (1) is firmly fixed.

이때, 슬리브관(10)과 쐐기(20)에 형성된 요철부(11)(21)들 사이에는 강한 마찰력이 발생되어 앵커볼트(30)의 하부에 구조물(40)을 설치하는 과정에서 충격이 발생되더라도 쐐기(20)가 슬리브관(10)에서 이탈되지 않는 것이므로 구조물(40)의 낙하가 방지되어 안전한 작업을 수행할 수 있는 등의 이점이 있는 것이다.At this time, a strong friction force is generated between the uneven parts 11 and 21 formed in the sleeve tube 10 and the wedge 20, and an impact occurs in the process of installing the structure 40 in the lower portion of the anchor bolt 30. Even if the wedge 20 is not to be separated from the sleeve tube 10, the fall of the structure 40 is prevented to have the advantage of being able to perform a safe operation.

한편, 상기 슬리브관(10)과 쐐기(20)에 형성된 요철부(11)(21)들은 그 단면 형상이 역삼각형 모양의 링형 돌기(11a)(21a)들이 상하 연속 형성되어 링형 돌기(11a)(21a)들이 일단 결합되면 걸림 작용과 강한 마찰력에 의하여 쐐기(20)가 슬리브관(10)에서 이탈되지 않도록 구성되어 있다.On the other hand, the uneven parts 11 and 21 formed in the sleeve tube 10 and the wedge 20 are ring-shaped protrusions 11a and 21a of an inverted triangular shape in cross-section and are continuously formed up and down to form a ring-shaped protrusion 11a. Once the 21a is coupled, the wedge 20 is configured not to be separated from the sleeve tube 10 by the locking action and the strong frictional force.

그러나, 경우에 따라서는 도 5에서 도시한 바와 같이 상기 슬리브관(10)과 쐐기(20)에 격자형의 홈들로 구성된 널링(11b)(21b)들을 각각 형성하여 요철부(11)(21)들을 형성할 수 있는 것이므로 본 발명에서는 요철부(11)(21)의 형상에 국한되는 것은 아니다.However, in some cases, as shown in FIG. 5, the knurled portions 11b and 21b formed of lattice grooves are formed in the sleeve tube 10 and the wedge 20, respectively, so that the uneven portions 11 and 21 are formed. The present invention is not limited to the shape of the uneven parts 11 and 21 in the present invention.

또한, 도 2∼도 4에 도시된 바로는 위가 넓고 아래로 갈수록 폭이 좁아지는 원추형 쐐기(20)를 슬리브관(10)의 상부에 결합하여 구멍(1)의 하부로 돌출되는 슬리브관(10)을 타격하여 쐐기를 고정시킬 수 있도록 구성되어 있으나, 도 6a에서 도시한 바와 같이 위가 좁고 아래로 갈수록 폭이 넓어지는 원추형 쐐기(20)를 슬리브관(10)의 하부로부터 상부에 결합하여 공구를 사용하여 쐐기(20)의 하부를 타격하면 도 6b에서 도시한 바와 같이, 슬리브관(10)의 내부 상측에 형성된 경사면(14)에 쐐기(20)가 접촉되어 쐐기(20)가 고정되도록 할 수도 있다.In addition, the bar shown in Figures 2 to 4 is coupled to the upper portion of the sleeve tube 10, the conical wedge 20 is wider and narrower toward the bottom of the sleeve tube (protruding to the lower portion of the hole 1) 10) but is configured to be fixed to the wedge, but as shown in Figure 6a by narrowing the conical wedge 20, the upper narrower and wider toward the lower side by combining from the bottom of the sleeve tube 10 to the top When the bottom of the wedge 20 is hit by using a tool, as shown in FIG. 6B, the wedge 20 contacts the inclined surface 14 formed on the inner upper side of the sleeve tube 10 so that the wedge 20 is fixed. You may.

이때, 슬리브관(10)의 요철부(11)는 경사면(14)에 형성되어 쐐기(20)의 외주면에 형성된 요철부(21)와 접촉되면서 강한 마찰력을 형성할 수 있도록 구성되어 있다.At this time, the uneven portion 11 of the sleeve tube 10 is formed on the inclined surface 14 is configured to form a strong friction while being in contact with the uneven portion 21 formed on the outer peripheral surface of the wedge 20.
