일반적으로 앵커볼트는 건축물의 콘크리트 벽체나 바닥 또는 천정등에 어떠한 물체를 고정시키기 위해 사용되는 것으로, 근래 널리 사용되고 있는 앵커볼트는 도 1a와 도 1b에 도시된 바와 같이 나사부(1),멈춤턱부(2),연결부(3) 및 확장부(4)를 일체로 구비하는 볼트부재(5)와; 다수개의 절개부(6) 및 걸림돌기(7)를 구비하여 볼트부재(5)의 연결부(3)에 끼워지는 슬리브(8)로 구성된다. 이때, 슬리브(8)와 나사부(1),멈춤턱부(2),확장부(4)의 외경은 동일한 직경으로 형성된다.In general, the anchor bolt is used to fix any object on the concrete wall or floor or ceiling of the building, the anchor bolt that is widely used in recent years, as shown in Figure 1a and Figure 1b (1), stop jaw (2) ), A bolt member 5 having a connecting portion 3 and an expansion portion 4 integrally; It is composed of a sleeve (8) having a plurality of cutouts (6) and engaging projections (7) fitted to the connecting portion (3) of the bolt member (5). At this time, the outer diameters of the sleeve 8, the threaded portion 1, the stopping jaw portion 2, and the expanded portion 4 are formed to the same diameter.

그러나, 이와 같이 구성된 종래의 앵커볼트는 슬리브(8)가 빠지는 것을 방지하는 멈춤턱부(2)가 볼트부재(5)에 일체로 형성되고 또한 구조적으로 슬리브(8)와 확장부(4) 및 멈춤턱부(2)의 외경이 동일한 직경으로 형성되었기 때문에, 조립시 슬리브(8)를 외측으로 벌려서 연결부(3)에 끼운 후 다시 슬리브(8)를 원상태로 오므려야 하는 불편함으로 인해 슬리브(8)의 조립성이 떨어지는 문제점이 있었다.However, in the conventional anchor bolt configured as described above, the stopping jaw portion 2 which prevents the sleeve 8 from being pulled out is integrally formed on the bolt member 5, and structurally, the sleeve 8 and the expansion portion 4 and the stopping portion are stopped. Since the outer diameter of the jaw portion 2 is formed with the same diameter, the sleeve 8 is uncomfortable due to the inconvenience of having to open the sleeve 8 outward and insert it into the connecting portion 3 and then retract the sleeve 8 to its original state during assembly. There was a problem of poor assembly.

본 고안의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해 안출한 것으로, 조립시 슬리브를 벌리지 않고도 연결부에 간단하게 끼울 수 있도록 슬리브의 조립구조를 개선하여 슬리브의 조립성을 향상시킬 수 있도록 한 앵커볼트를 제공하는 데 있다.An object of the present invention is to solve the conventional drawbacks as described above, to improve the assembly of the sleeve to improve the assembly structure of the sleeve so that it can be easily fitted to the connecting portion without opening the sleeve during assembly. To provide anchor bolts.

상기 목적을 달성하기 위해 본 고안은 볼트부재의 나사부를 통해 연결부에 직접 슬리브를 끼울 수 있도록 나사부의 외경을 연결부의 외경과 동일하게 형성하고, 상기 연결부에 슬리브를 끼운 상태에서 멈춤링을 나사부에 끼워 가압하여 고정시킨 것이다.In order to achieve the above object, the present invention forms the outer diameter of the screw portion equal to the outer diameter of the connecting portion so that the sleeve can be directly fitted to the connecting portion through the screw portion of the bolt member, and the stop ring is inserted into the screw portion while the sleeve is fitted to the connecting portion.

본 고안의 앵커볼트는 도 2 내지 도 4에 도시되는 바와 같이, 나사부(11),연결부(12) 및 확장부(13)를 일체로 구비하는 볼트부재(10)와; 다수개의 절개부(21) 및 걸림돌기(22)를 구비하여 볼트부재(10)의 연결부(12)에 끼워지는 슬리브(20)로 구성되는 앵커볼트에 있어서, 상기 나사부(11)의 외경을 연결부(12)의 외경과 동일하게 형성하여 이 나사부(11)로 슬리브(20)를 끼워 연결부(12)에 위치시키고, 상기 슬리브(20)와 동일한 외경으로 형성된 멈춤링(30)을 나사부(11)에 끼워 가압하여 고정시킨 것을 그 기술적 구성상의 특징으로 한다.The anchor bolt of the present invention, as shown in Figure 2 to 4, the bolt member 10 having a screw portion 11, the connection portion 12 and the expansion portion 13 integrally; In the anchor bolt consisting of a sleeve 20 is provided with a plurality of cutouts 21 and the engaging projection 22 to be fitted to the connecting portion 12 of the bolt member 10, the outer diameter of the screw portion 11 connecting portion It is formed in the same diameter as the outer diameter of (12), the sleeve 20 is sandwiched with the threaded portion 11 and positioned in the connecting portion 12, and the stop ring 30 formed with the same outer diameter as the sleeve 20 is threaded portion 11 It is characterized by the technical configuration of the clamped and fixed to the.

상기 볼트부재(10)는 나사부(11)와 연결부(12) 및 확장부(13)를 일체로 구비하는 것으로, 이때 나사부(11)는 슬리브(20)가 용이하게 끼워지도록 연결부(12)의 외경과 동일하게 형성된다.The bolt member 10 is provided with a threaded portion 11, the connection portion 12 and the expansion portion 13 integrally, wherein the threaded portion 11 is the outer diameter of the connection portion 12 so that the sleeve 20 is easily fitted Is formed the same as

따라서 본 고안에서는 조립시 종래와 같이 슬리브(20)를 벌리지 않고서도 나사부(11)로 슬리브(20)를 간단하게 끼워 연결부(12)에 조립할 수 있다.Therefore, in the present invention, the sleeve 20 may be easily fitted into the connecting portion 12 by screwing the screw 11 without opening the sleeve 20 as in the prior art.

상기 멈춤링(30)은 연결부(12)에 끼워진 슬리브(20)가 빠지는 것을 방지하는 것으로, 이러한 멈춤링(30)은 나사부(11)로 끼워져 나사부(11)와 연결부(12)의 경계면인 나사부(11) 하부에 위치되어 외부에서 기계적인 힘으로 가압함에 의해 나사부(11)에 일체형으로 간단하게 고정된다. 이때, 멈춤링(30)의 외경은 슬리브(20)의 외경과 동일하게 형성된다.The stop ring 30 is to prevent the sleeve 20 fitted into the connecting portion 12 is pulled out, this stop ring 30 is fitted into the threaded portion 11, the threaded portion that is the interface between the threaded portion 11 and the connection portion 12 (11) It is located at the bottom and is simply fixed integrally to the threaded portion 11 by pressurizing with mechanical force from the outside. At this time, the outer diameter of the stop ring 30 is formed the same as the outer diameter of the sleeve (20).

이와 같이 구성된 본 고안은 조립시 슬리브(20)를 벌리지 않고서도 나사부 (11)로 슬리브(20)를 간단하게 끼워 연결부(12)에 위치시킨 후, 나사부(11)에 멈춤링(30)을 끼운 상태에서 외부에서 간단하게 기계적인 힘으로 가압하여 고정시킬 수 있으므로 슬리브(20)의 조립성을 향상시킬 수 있는 장점이 있다.According to the present invention configured as described above, the sleeve 20 is simply inserted into the connection part 12 by the screw part 11 without opening the sleeve 20 during assembly, and then the stop ring 30 is inserted into the thread part 11. Since the state can be fixed by simply pressing the mechanical force from the outside there is an advantage that can improve the assembly of the sleeve (20).

이하에서는 본 고안의 앵커볼트를 콘크리트 바닥에 고정시키는 방법을 도 4를 참조하여 설명한다.Hereinafter, a method of fixing the anchor bolt of the present invention to the concrete floor will be described with reference to FIG. 4.

먼저 도 4에서와 같이 볼트부재(10)를 삽입하기 위한 구멍(41)을 콘크리트 바닥(40)에 형성한다. 이때, 구멍(41)은 슬리브(20)와 확장부(13) 및 멈춤링(30)의 외경과 같은 크기로 형성하되, 구멍(41)의 깊이는 정확하게 형성할 필요 없이 규정치 이상만 되면 삽입하는데 문제가 없다.First, as shown in FIG. 4, a hole 41 for inserting the bolt member 10 is formed in the concrete floor 40. At this time, the hole 41 is formed in the same size as the outer diameter of the sleeve 20, the expansion portion 13 and the stop ring 30, the depth of the hole 41 need not be formed accurately, but inserts as long as it exceeds the prescribed value No problem.

상기 구멍(41)에 볼트부재(10)를 삽입할 때는 망치등으로 살짝 두드리면 되는데, 슬리브(20)의 걸림돌기(22)가 구멍(41)의 크기보다 조금 더 돌출되어 있으므로 손으로는 밀어 넣을 수가 없고 망치등으로 가볍게 타격하면 멈춤링(30)이 슬리브(20)를 밀고 들어가므로 걸림돌기(22)가 구멍(41)의 내벽을 조금씩 긁으면서 삽입된다. 이때 볼트부재(10)를 삽입하는 깊이는 고정되었을 때의 필요한 길이보다 조금 더 삽입한다.When the bolt member 10 is inserted into the hole 41, a tap or the like may be used. However, since the locking protrusion 22 of the sleeve 20 protrudes a little more than the size of the hole 41, it is pushed by hand. If you can not hit lightly with a hammer or the like, the stop ring 30 is pushed into the sleeve 20, so that the engaging projection 22 is inserted while scratching the inner wall of the hole 41 little by little. At this time, the depth to insert the bolt member 10 is inserted a little more than the required length when fixed.

상기와 같은 상태에서 나사부(11)에 조임너트(50)를 체결하여 조이면 볼트부재(10)가 외부로 빠지면서 고정되는데, 이때 슬리브(20)는 걸림돌기(22)에 의해 구멍(41)의 내벽에 견고하게 고정되어 외부로 빠져나올 수 없는 상태이므로 조임너트(50)를 조이면 볼트부재(10)만이 외부로 서서히 빠져나온다.When the fastening nut 50 is tightened by tightening the fastening nut 50 in the above state, the bolt member 10 is fixed while being pulled out, and the sleeve 20 is fixed to the inner wall of the hole 41 by the locking protrusion 22. Since it is in a state that is firmly fixed to and cannot escape to the outside, tightening the tightening nut 50 only the bolt member 10 is gradually released to the outside.

따라서 다수개의 절개부(21)가 형성된 슬리브(20)의 하단이 확장부(13)에 의해 확장되면서 구멍(41)의 내벽에 강하게 밀착되므로 앵커볼트가 구멍(41)에 완전히 고정되는 것이다.Therefore, the lower end of the sleeve 20 in which the plurality of cutouts 21 are formed is strongly adhered to the inner wall of the hole 41 while being expanded by the expansion part 13 so that the anchor bolt is completely fixed to the hole 41.

이상에서 살펴본 바와 같이 본 고안의 앵커볼트는 조립시 슬리브를 벌리지 않고 나사부를 통해 연결부에 슬리브를 간단하게 직접 끼운 후, 슬리브가 빠지지 않도록 나사부에 멈춤링을 끼운 상태에서 간단하게 가압하여 고정시키므로 슬리브의 조립성을 향상시킬 수 있는 매우 유용한 고안이다.As described above, the anchor bolt of the present invention simply inserts the sleeve directly into the connecting portion through the screw portion without opening the sleeve when assembling, and then simply presses and fixes the screw in the state where the stop ring is inserted to prevent the sleeve from being pulled out. It is a very useful design that can improve the assembly.
