Description

앵커볼트{Anchor bolt}Anchor Bolt

본 고안은 앵커볼트에 관한 것으로서, 특히 큰 하중이 연속적으로 반복해서작용해도 기초로부터 뽑히지 않을 뿐 아니라 하중에 견디는 힘 또한 우수하며, 작동과정이 부드럽게 이루어지도록 한 앵커볼트에 관한 것이다.The present invention relates to anchor bolts, in particular, a large load is applied to the anchor bolt not only pulled out from the foundation, but also excellent in load-bearing force, and the operation process is made smoothly.

도 1은 종래기술에 따른 앵커볼트가 도시된 분해사시도이고, 도 2는 종래기술에 따른 앵커볼트가 도시된 사용상태도이다.1 is an exploded perspective view showing an anchor bolt according to the prior art, Figure 2 is a use state diagram showing the anchor bolt according to the prior art.

앵커볼트는 콘크리트나 철근콘크리트의 기초에 피고정물(구조물이나 기계 따위)을 정착시키는 것으로서, 도 1 및 도 2에서와 같이 상측에 나사부(11)가 형성되고 하단에 하측으로 갈수록 외주가 커지는 확장부(12)가 형성되는 볼트(10)와, 하측에 하단이 벌어질 수 있도록 다수의 절개부(21)가 형성되어 절개부(21)와 확장부(12)가 맞닿도록 상기 볼트(10)가 삽입되는 슬리브(20)와, 상기 볼트(10)의 나사부(11)와 결합되는 체결너트(30)로 구성된다.The anchor bolt is to fix the fixed object (such as a structure or a machine) on the foundation of concrete or reinforced concrete, as shown in Figs. 1 and 2, the screw 11 is formed on the upper side and the outer portion becomes larger toward the lower side at the bottom A bolt 10 having a 12 formed therein, and a plurality of cutouts 21 formed at the lower side thereof so that the bolts 10 are brought into contact with the cutout 21 and the extension 12. It consists of a sleeve 20 to be inserted, and a fastening nut 30 coupled to the threaded portion 11 of the bolt 10.

여기에서 상기 슬리브(20)는 그 내경이 확장부(12)의 최대외경에 비해 작도록 형성된다.Here, the sleeve 20 is formed such that its inner diameter is smaller than the maximum outer diameter of the extension 12.

따라서 기초(F)에 구멍(H)을 천공한 후 여기에 나사부(11)의 끝이 외부로 돌출되도록 볼트(10)를 끼운 다음 볼트(10)의 외주에 슬리브(20)를 끼우고 체결너트(30)를 나사부(11)와 결합시켜 조이면 볼트(10)는 직선 운동하며 그 확장부(12)가 슬리브(20)의 내부로 진입하게 되고, 슬리브(20)는 확장부(12)에 의해 절개부(21)를 기준으로 해 갈라지며 벌어져 구멍(H)에 밀착, 기초(F)에 고정된다.Therefore, after drilling the hole (H) in the base (F), the bolt 10 is inserted therein so that the end of the threaded portion 11 protrudes to the outside, and then the sleeve 20 is inserted in the outer circumference of the bolt 10 and the fastening nut When the 30 is coupled to the screw 11 and tightened, the bolt 10 moves linearly, and the extension 12 enters the inside of the sleeve 20, and the sleeve 20 is extended by the extension 12. It is divided based on the cutout portion 21, and is opened and adhered to the hole H and fixed to the base F.

그러나 종래기술의 앵커볼트는 슬리브(20)의 표면이 매끄럽도록 형성되었을 뿐 아니라 단순히 절개부(21)에 의해 벌어지는 부분의 작용으로 고정되기 때문에 큰 하중이 연속적으로 반복해서 작용할 경우, 즉 반복하중이 가해질 시 기초(F)로부터 뽑히게 되는 문제점이 있다.However, the anchor bolt of the prior art is not only smoothly formed on the surface of the sleeve 20, but also fixed simply by the action of the opening part by the incision 21, so that a large load is repeatedly operated, that is, repeated load. There is a problem that is drawn from the base (F) when this is applied.

또한 볼트(10)에 있어서, 그 확장부(12)를 제외한 나머지 부분의 외주가 동일하도록 형성되기 때문에 나사부(11)와 확장부(12) 사이의 목부에 하중에 집중적으로 작용해 그 작용하중이 최고조로 달하였을 시 목부가 변형, 즉 늘어나거나 끊어지게 되는 문제점이 있다.In addition, in the bolt 10, the outer periphery of the remaining portions except for the extension portion 12 is formed to be the same, so that the neck portion between the threaded portion 11 and the extension portion 12 is concentrated on the load and its working load is increased. When the peak is reached, there is a problem that the neck is deformed, that is, stretched or broken.

또한 슬리브(20)의 하단 내주면이 각지게 형성되기 때문에 슬리브(20)의 내부로 확장부(12)를 진입시킬 시 걸림작용에 의해 진입작동이 부드럽지 못해 많을 힘을 필요로 하는 문제점이 있다.In addition, since the lower inner circumferential surface of the sleeve 20 is formed at an angle, there is a problem in that a large amount of force is required because the entry operation is not smooth due to a locking action when the expansion part 12 enters the inside of the sleeve 20.

본 고안은 종래기술의 문제점을 해결하기 위해 안출된 것으로서, 슬리브에 턱을 형성함으로써 이 턱의 걸림작용으로 기초로부터 빠지는 것을 방지할 수 있고, 볼트의 외주를 크도록 형성되어 강도가 우수하며, 슬리브에 볼트의 진입을 유도할 수 있도록 경사를 형성함으로써 진입작동을 부드럽도록 한 앵커볼트를 제공하는 데 목적이 있다.The present invention has been devised to solve the problems of the prior art, by forming a jaw in the sleeve to prevent it from falling off the foundation due to the locking action of the jaw, formed to increase the outer circumference of the bolt is excellent in strength, the sleeve An object of the present invention is to provide an anchor bolt that softens the entry operation by forming a slope so as to induce the entry of bolts.

이하 첨부도면을 참조해 본 고안의 바람직한 실시예를 설명하되 편의상 종래기술과 동일 구성요소는 동일 도면부호를 사용하기로 한다.DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. For convenience, the same components as in the prior art will be denoted by the same reference numerals.

본 고안에 따른 앵커볼트가 도 3 내지 도 6에 도시되어 있다.An anchor bolt according to the present invention is shown in Figures 3 to 6.

도 3 내지 도 6에서와 같이 본 고안에 따른 앵커볼트는 상측의 외주에 나사부(11)가 형성되고 하단에 하측으로 갈수록 점차 외주가 커지는 확장부(12)가 형성되는 볼트(10)와, 기다란 파이프형상으로 형성되고 하측에 하단이 벌어질 수 있도록 다수의 절개부(21)가 형성되어 이 절개부(21)와 확장부(12)가 맞닿도록 내부로 상기 볼트(10)가 삽입되는 슬리브(20)와, 상기 볼트(10)의 나사부(11)와 나사 결합되는 체결너트(30)와, 상기 체결너트(30)의 풀림을 방지하는 평와셔(41) 및 스프링와셔(42)로 구성된다.3 to 6, the anchor bolt according to the present invention is the bolt portion 10 is formed on the outer periphery of the upper side and the expansion portion 12 is formed to gradually increase the outer periphery toward the lower side at the lower end, elongated A sleeve in which the bolt 10 is inserted into the pipe shape and a plurality of cutouts 21 are formed to have a lower end at the lower side thereof so that the cutout 21 and the expansion part 12 are in contact with each other ( 20), a fastening nut 30 screwed to the threaded portion 11 of the bolt 10, and a flat washer 41 and a spring washer 42 for preventing the fastening nut 30 from loosening. .

여기에서 상기 슬리브(20)는 그 내경이 확장부(12)의 최대외경, 즉 하단에 비해 작도록 형성된다.Here, the sleeve 20 is formed such that the inner diameter thereof is smaller than the maximum outer diameter of the extension 12, that is, the lower end thereof.

특히 본 고안에 있어서, 상기 볼트(10)는 나사부(11)와 확장부(12) 사이에서 나사부(11)와 확장부(12)를 일체로 연결하는 목부(101)가 나사부(11)의 외주(A)에 비해 그 외주(B)가 약간 크도록 형성되고, 상기 확장부(12)의 하단에는 이 하단과 동일한 외주를 갖는 소정 길이의 연장부(102)가 일체로 형성된다.In particular, in the present invention, the bolt 10 has a neck portion 101 which integrally connects the threaded portion 11 and the extended portion 12 between the threaded portion 11 and the extended portion 12 is the outer periphery of the threaded portion 11 The outer periphery B is formed slightly larger than (A), and an extension part 102 of a predetermined length having the same outer periphery as the lower end is integrally formed at the lower end of the extension part 12.

그리고 상기 슬리브(20)는 외주면에 외주방향을 따라 다수의 걸림턱부(111)가 형성되고, 하단의 내주면에는 하측으로 갈수록 내주가 점차 커지도록 내주방향을 따라 경사부(112)가 형성된다.In addition, the sleeve 20 has a plurality of locking jaw portions 111 formed on the outer circumferential direction along the outer circumferential surface, and an inclined portion 112 is formed along the inner circumferential direction on the inner circumferential surface of the lower portion so that the inner circumference gradually increases toward the lower side.

여기에서 상기 걸림턱부(111)는 "∨" 형상으로 형성되는 것으로서, 상기 슬리브(20)의 길이방향을 따라 배치되는 다수 개, 즉 3개를 1조로 한다.Here, the locking step 111 is formed in a "∨" shape, a plurality of dogs arranged along the longitudinal direction of the sleeve 20, that is, three in one set.

이러한 걸림턱부(111)는 재료를 절감하고자 내측에서 외측으로 공지의 프레스에 의해 눌러 찍음으로써 절곡시켜 외측으로 돌출되도록 형성되는 바, 이 걸림턱부(111)에 의해 슬리브(20)의 외주면에는 요철이 형성되고, 이로써 슬리브(20)는 자체두께의 변화 없이(원재료의 추가 없이) 자체강도가 향상된다.The locking jaw portion 111 is formed to be bent by pressing by pressing a press from the inside to the outside to reduce the material to protrude outwards, the outer circumferential surface of the sleeve 20 by the locking jaw portion 111 is uneven The sleeve 20 is thereby formed so that its strength is improved without changing its thickness (without addition of raw materials).

즉 상기 슬리브(20)의 자체두께와 걸림턱부(111)의 두께로 슬리브(20)의 전체두께가 두꺼워져 자체강도가 향상되는 결과를 얻을 수 있게 되는 것이다.That is, the entire thickness of the sleeve 20 is thickened by the thickness of the sleeve 20 and the locking jaw portion 111 so that the result is that the strength of the sleeve 20 is improved.

이 때 상기 걸림턱부(111)는 하측에서 상측으로 갈수록 오르막 경사지도록 형성된다.At this time, the locking jaw 111 is formed to be inclined uphill from the lower side to the upper side.

한편 상기 걸림턱부(111)는 다른 예로써 "―" 형상이나 "∪" 형상으로 형성될 수도 있다.On the other hand, the locking step 111 may be formed in a "-" shape or "∪" shape as another example.

상기에서와 같은 본 고안의 설치과정 및 그 작용을 살펴보면 아래와 같다.Looking at the installation process and the operation of the present invention as described above are as follows.

먼저 도 2에서와 마찬가지로 기초(도 2의 도면부호 F)에 구멍(도 2의 도면부호 H)을 천공한 후 여기에 나사부(11)의 끝이 외부로 돌출되도록 볼트(10)를 끼운 다음 볼트(10)의 외주에 슬리브(20)를 끼운다.First, as in FIG. 2, a hole (reference H in FIG. 2) is drilled in the base (F in FIG. 2), and then the bolt 10 is inserted so that the end of the threaded portion 11 protrudes outward, and then the bolt The sleeve 20 is fitted to the outer circumference of the 10.

이 때 슬리브(20)는 걸림턱부(111)가 하측에서 상측으로 갈수록 오르막 경사지도록 형성되므로 기초의 구멍에 이 구멍과 걸림됨이 없이 용이하게 끼워진다.At this time, the sleeve 20 is formed so that the locking step 111 is inclined uphill from the lower side to the upper side, it is easily inserted into the hole of the foundation without being caught with the hole.

다음 볼트(10)의 외주에 피고정물, 평와셔(41) 및 스프링와셔(42)를 순차적으로 끼운 후 볼트(10)의 나사부(11)에 체결너트(30)를 결합해 조인다.Next, the fixed object, the flat washer 41 and the spring washer 42 are sequentially inserted into the outer circumference of the bolt 10, and then the fastening nut 30 is coupled to the threaded portion 11 of the bolt 10.

따라서 볼트(10)는 체결너트(30)의 회전운동으로 직선 운동하며 그 확장부(12)가 슬리브(20)의 내부로 진입하게 된다.Accordingly, the bolt 10 linearly moves by the rotational movement of the fastening nut 30 and the extension 12 enters the inside of the sleeve 20.

이 때 슬리브(20)의 경사부(112)는 그 내부로 볼트(12)가 자연스럽게 진입할 수 있도록 확장부(12)를 안내한다.At this time, the inclined portion 112 of the sleeve 20 guides the expansion portion 12 so that the bolt 12 can naturally enter the inside.

이처럼 슬리브(20)의 내부로 확장부(12)를 진입시키면 확장부(12)에 의해 슬리브(20)는 절개부(21)를 기준으로 해 갈라지며 벌어져 구멍의 내주면에 밀착되고, 이에 본 고안은 기초(F)에 고정되며, 피고정물은 기초에 정착된다.As such, when the expansion portion 12 enters the inside of the sleeve 20, the sleeve 20 is separated and opened based on the cutout portion 21 by the expansion portion 12 to be in close contact with the inner circumferential surface of the hole. Is fixed to the foundation F, and the fixed object is fixed to the foundation.

상기의 상태에서 본 고안에 큰 하중이 반복적으로 연속해서 작용하면 본 고안은 기초로부터 뽑히는 힘을 받게 되나, 기초의 구멍에 걸림되는 걸림턱부(111)로 인해 본 고안은 기초로부터 뽑히는 것이 방지된다.In the above state, if a large load repeatedly acts on the present invention repeatedly, the present invention receives a force pulled from the foundation, but the present invention is prevented from being pulled from the foundation due to the locking jaw portion 111 caught in the hole of the foundation.

아울러 상기의 경우 목부(101)에 커다란 힘이 함께 작용하는데, 이 때 목부(101)는 그 외주가 나사부(11)에 비해 크도록 형성되므로 늘어나거나 끊어지는 등의 변형이 방지된다.In addition, in the above case, a large force acts together on the neck portion 101, at which time the neck portion 101 is formed so that its outer circumference is larger than that of the screw portion 11, so that deformation such as stretching or breaking is prevented.

또한 불가피하게 기초로부터 본 고안이 뽑히더라도 볼트(10)의 전체길이가 연장부(102)에 의해 길도록 형성된 탓에 이 연장부(102)의 길이에 상응해 뽑히는 시간이 지연된다.In addition, even if the present invention is inevitably pulled out from the foundation, the overall length of the bolt 10 is formed to be long by the extension 102, so that the time for pulling out corresponding to the length of the extension 102 is delayed.

이상에서 설명한 바와 같은 본 고안은 슬리브의 외주면에 절곡되어 돌출된 걸림턱부가 형성되기 때문에 자체두께의 변화 없이 자체강도를 향상시킬 수 있음은 물론 기초로부터 뽑히는 힘을 받을 시 구멍에 걸림되므로 이에 기초로부터 뽑히는 것을 방지할 수 있고, 하단의 내주면에 경사부가 형성되어 내부로 볼트가 자연스럽게 진입할 수 있도록 확장부를 안내하므로 작동관계가 부드러우며, 볼트의 목부가 나사부에 비해 외주가 크도록 형성되기 때문에 강도가 우수하고, 하단에 전체길이를 연장하는 연장부가 형성되어 불가피하게 뽑히게 될 경우 연장부의 길이에 상응해 뽑히는 시간을 지연할 수 있는 이점이 있다.The present invention as described above can be improved on its own strength without changing its thickness because it is formed on the outer circumferential surface of the sleeve and protrudes, so that it is caught in the hole when the force is pulled from the foundation. It can be prevented from being pulled out, and the slope is formed on the inner circumferential surface of the lower part to guide the expansion part so that the bolt can naturally enter the inside, so that the operating relationship is smooth, and because the neck of the bolt is formed so that the outer circumference is larger than the screw part, the strength is increased. Excellent, there is an advantage that can be delayed the time to be pulled corresponding to the length of the extension if the extension is formed to extend the entire length at the bottom inevitable.
