Description

앵커 볼트{ANCHOR BOLT}Anchor bolts {ANCHOR BOLT}

본 발명은 앵커 볼트에 관한 것으로, 더욱 상세하게는 단조를 통해 볼트부재의 구조를 개선하여 별도의 고정 슬리브를 사용하지 않아도 정착력을 확보할 수 있는 앵커 볼트에 관한 것이다.The present invention relates to an anchor bolt, and more particularly to an anchor bolt that can secure the fixing force without using a separate fixing sleeve by improving the structure of the bolt member through forging.

그리고, 본 발명은 고정 슬리브를 사용하되, 고정 슬리브가 앵커공에 정착되어 볼트부재의 정착력을 증대함으로써 설치 구조물을 효과적으로 지지할 수 있는 앵커 볼트에 관한 것이다.
In addition, the present invention relates to an anchor bolt using a fixed sleeve, which can effectively support the installation structure by fixing the fixed sleeve to the anchor hole to increase the fixing force of the bolt member.

일반적으로, 앵커볼트(Anchor Bolt)는 콘크리트로 된 건축물의 벽이나 바닥 또는 천정 등에 기계류와 프레임 및 철골 등의 중량을 가진 장비와 구조물 등을 설치할 때 고정력을 제공하기 위해 사용되고 있다.In general, anchor bolts (Anchor Bolt) is used to provide a fixed force when installing equipment and structures having a heavy weight, such as machinery, frames and steel frame, etc. on the wall or floor or ceiling of a concrete building.

이러한 앵커볼트의 작동원리는 볼트부재에 끼워진 확장 슬리브가 선단에 형성된 확대부에 의해 벌어지면서 콘크리트 기초의 구멍에 밀착되어 볼트부재를 고정시키게 되며, 상기 확장 슬리브를 벌어지도록 하는 방법에 따라 전용공구를 이용하여 슬리브를 강타하여 벌리는 타입과, 볼트부재의 나사부에 너트를 체결하여 조여줄 때 가해지는 힘에 의해 슬리브가 벌어지도록 하는 타입 등이 있다.The principle of operation of the anchor bolt is to expand the sleeve to the bolt member by the enlarged portion formed in the tip is in close contact with the hole of the concrete foundation to fix the bolt member, according to the method to open the expansion sleeve There is a type to be swung apart by using the sleeve, and a type to open the sleeve by the force applied when tightening and tightening the nut to the screw portion of the bolt member.

도 1은 종래의 앵커볼트의 일예에 대한 시공상태를 나타낸 단면도로서, 먼저 앵커볼트(10)는 볼트부재(11), 볼트부재(11)의 확경 헤드부(11a)에 결합되는 확장 슬리브(12), 볼트부재(11)의 나사부(11b)에 나사 체결되어 확장 슬리브(12)의 확장을 유도하는 너트(13)로 구성된다.1 is a cross-sectional view showing a construction state for an example of a conventional anchor bolt, first anchor bolt 10 is an expansion sleeve 12 is coupled to the bolt member 11, the expansion head portion 11a of the bolt member 11 ), The screw 13 is screwed to the threaded portion 11b of the bolt member 11 to induce expansion of the expansion sleeve 12.

이와 같은 구성의 앵커 볼트(10)의 시공 방법을 설명하면, 콘크리트 기초(1)에 드릴 등을 이용하여 앵커공(2)을 뚫고, 볼트부재(11)의 선단에 형성된 확경 헤드부(11a)의 외주면에 확장 슬리브(12)를 끼운 후 그 볼트부재(11)를 앵커공(2)에 삽입한다. 그 다음 볼트부재(11)를 타격하거나 너트(13)를 체결하면 확장 슬리브(12)의 슬롯(12a) 부위가 벌어지면서 변형되어 확장 슬리브(12)가 앵커공(2) 내주면에 밀착됨으로써 볼트부재(11)가 앵커공(2)에서 빠지지 않게 고정된다. 여기서 설치 대상의 프레임(3)을 너트(13)와 콘크리트 기초(1) 사이에 개재함으로써 앵커 볼트(10)를 통해 프레임(3)을 콘크리트 기초(1)에 설치하는 것이다.
Referring to the construction method of the anchor bolt 10 having such a configuration, the diameter of the enlarged head portion 11a formed at the tip of the bolt member 11 by drilling the anchor hole 2 using a drill or the like to the concrete foundation 1. Insert the expansion sleeve 12 to the outer peripheral surface of the bolt member 11 is inserted into the anchor hole (2). Then, when the bolt member 11 is hit or the nut 13 is fastened, the slot 12a portion of the expansion sleeve 12 is opened and deformed so that the expansion sleeve 12 comes into close contact with the inner circumferential surface of the anchor hole 2 so that the bolt member 11 is fixed not to fall out of the anchor hole (2). Here, the frame 3 is installed on the concrete foundation 1 via the anchor bolt 10 by interposing the frame 3 to be installed between the nut 13 and the concrete foundation 1.

한편, 종래 앵커 볼트(10)의 볼트부재(11)는 확장 슬리브(12)의 확장을 위하여 확경 헤드부(11a)의 단부로부터 일정 거리 이격된 둘레부에 환형의 턱(11c)이 형성될 수밖에 없으며, 이 턱(11c)으로 인하여 볼트부재(11)의 둘레부는 앵커공(2)의 내벽에 정착되지 못한다. 왜냐하면, 볼트부재(11)의 턱(11c)에 의해 나사부(11b)와 앵커공(2)의 내벽 사이에는 턱(11c)의 두께만큼 간극이 발생되기 때문이다.On the other hand, the bolt member 11 of the conventional anchor bolt 10 has an annular jaw (11c) is formed in the periphery spaced a predetermined distance from the end of the diameter expansion head portion (11a) for expansion of the expansion sleeve 12 No, the periphery of the bolt member 11 can not be fixed to the inner wall of the anchor hole (2) due to this jaw (11c). This is because a gap is generated between the threaded portion 11b and the inner wall of the anchor hole 2 by the thickness of the tuck 11c by the tuck 11c of the bolt member 11.

확장 슬리브(12)가 앵커공(2)에 정착되지만 확장 슬리브(12)만으로는 볼트부재(11)의 큰 정착력을 확보하지 못하며 또한 이 부분(확장 슬리브(12)를 제외한 나머지 부분)에서 앵커공(2)에 대한 정착력이 매우 약하여 볼트부재(11)가 앵커공(2)에서 빠지게 됨에 따라 별도의 고정 슬리브(14)를 사용할 수밖에 없는 문제점이 있다.The expansion sleeve 12 is fixed to the anchor hole 2, but the expansion sleeve 12 alone does not secure a large fixing force of the bolt member 11, and also the anchor hole in this portion (except for the expansion sleeve 12). As the fixing force for (2) is so weak that the bolt member 11 is removed from the anchor hole 2, there is a problem that the separate fixing sleeve 14 must be used.

한편, 고정 슬리브(14)는 앵커공(2)의 내벽에 밀착되어야만 볼트부재(11)를 앵커공(2)에 정착시킬 수 있는데, 외경이 앵커공(2)보다 크면 앵커공(2)에 삽입하는 것이 어렵기 때문에 앵커공(2)의 내경보다 작은 외경으로 형성되며, 따라서, 고정 슬리브(14)의 외주면과 앵커공(2)의 내벽간의 마찰력이 약하기 때문에 슬립이 발생되므로 앵커 볼트(10)의 정착력에 큰 도움을 주지 못하는 문제점도 있다.
On the other hand, the fixing sleeve 14 must be in close contact with the inner wall of the anchor hole (2) to fix the bolt member 11 to the anchor hole (2), if the outer diameter is larger than the anchor hole (2) to the anchor hole (2) Since it is difficult to insert, it is formed to an outer diameter smaller than the inner diameter of the anchor hole (2), and therefore, because the friction force between the outer circumferential surface of the fixing sleeve 14 and the inner wall of the anchor hole (2) is weak because slip is generated, the anchor bolt (10) There is also a problem that does not give a great help to the fixing power of).

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 별도의 고정 슬리브를 사용하지 않고 볼트부재를 앵커공의 내벽에 밀착시켜 큰 정착력을 발생토록 함으로써 앵커공에 견고하게 정착되는 앵커 볼트를 제공하려는데 목적이 있다.The present invention is to solve the problems described above, to provide an anchor bolt that is firmly fixed to the anchor hole by causing the bolt member to be in close contact with the inner wall of the anchor hole without generating a separate fixing sleeve to generate a large fixing force. There is a purpose.

본 발명의 다른 목적은 별도의 고정 슬리브를 사용하더라도 고정 슬리브가 앵커공에 간섭되지 않고 원활하게 삽입되고 너트 등의 체결시 고정 슬리브가 확장되어 앵커공에 대한 큰 정착력을 발생시키려는데 있다.Another object of the present invention, even if a separate fixing sleeve is used to smoothly insert the fixing sleeve without interfering with the anchor hole, and when the fastening of the nut or the like to expand the fixing sleeve to generate a large fixing force for the anchor hole.

볼트부재(110)는 일측에서부터 확경 헤드부(111), 정착부(112) 및 체결부(113)로 구성된다.The bolt member 110 is composed of a diameter-expansion head 111, the fixing unit 112 and the fastening portion 113 from one side.

확경 헤드부(111)는 확장 슬리브(120)가 결합 및 확장 슬리브(120)의 확장을 유도하는 것으로, 단부로 가면서 점진적으로 직경이 커지도록 즉 테이퍼 형태로 형성된다.The enlarged diameter head 111 is an expansion sleeve 120 is coupled to guide the expansion of the expansion sleeve 120, is formed in a tapered shape so that the diameter gradually increases toward the end.

정착부(112)는 확경 헤드부(111)의 일측 단부에서부터 형성되며 확경 헤드부(111)보다 큰 직경(앵커공(2)의 내경)으로 형성되어 외주면이 앵커공(2)에 밀착됨으로써 별도의 슬리브 없이 자체적으로 정착력을 발생한다.The fixing unit 112 is formed from one end of the diameter-diameter head portion 111 and is formed with a diameter larger than the diameter-diameter head portion 111 (the inner diameter of the anchor hole 2) so that the outer circumferential surface is in close contact with the anchor hole 2 to separate it. The fixing force itself occurs without the sleeve.

정착부(112)는 확경 헤드부(111)의 둘레부에 결합된 확장 슬리브(120)가 미끄러지지 않도록 턱(112a)을 사이에 두고 형성된다. 턱(112a)은 확장 슬리브(120)가 빠지지 않도록 확경 헤드부(111)에 대해 직각으로 형성된다.The fixing unit 112 is formed with the jaw 112a interposed therebetween so that the expansion sleeve 120 coupled to the circumference of the enlarged diameter head unit 111 does not slip. The jaw 112a is formed at a right angle with respect to the enlarged diameter head 111 so that the expansion sleeve 120 does not fall out.

체결부(113)는 정착부(112)에서부터 형성되며 둘레부에 나사선이 형성되어 너트(130)가 체결된다.The fastening part 113 is formed from the fixing part 112, and a screw line is formed at the circumference to fasten the nut 130.

이와 같은 구조의 앵커 볼트(100)는 다음과 같은 공정을 통해 단조 가공된다.The anchor bolt 100 of such a structure is forged by the following process.

(S10) 모재 준비.(S10) Base material preparation.

앵커 볼트의 제조를 위한 모재(A)로서 단면의 변화가 없는 길이가 긴 봉을 준비한다.
As a base material A for manufacture of an anchor bolt, the long rod which does not change a cross section is prepared.

(S20) 1차 단조.(S20) 1st forging.

모재(A)의 두부를 단조하여 확경 헤드부의 가공을 위하여 1차 단조한다. 1차 단조에 의해 모재(A)는 대경부(A-1)와 소경부(A-2)로 구성되며, 즉, 모재(A)의 두부를 1차 단조함으로써 최초 모재(A)보다 길이가 길어지면서 직경이 작은 소경부(A-2)가 만들어진다. 예를 들어, 상부와 하부 금형으로 구분되며, 상부 금형에 소경부(A-2)의 직경을 갖는 펀치가 구성됨으로써 소경부(A-2)를 만들 수 있다.Forging the head of the base material (A) and forging first for processing the diameter-diameter head. By primary forging, the base material A is composed of a large diameter part A-1 and a small diameter part A-2. That is, the length of the base material A is greater than that of the initial base material A by primary forging the head of the base material A. As it grows, a small diameter portion (A-2) having a small diameter is made. For example, a small diameter portion A-2 may be formed by being divided into an upper mold and a lower mold, and having a punch having a diameter of the small diameter portion A-2 in the upper mold.

(S30) 2차 단조.(S30) Secondary forging.

이어서, 정착부(112)의 형성을 위하여 펀치를 통해 소경부(A-2)와 대경부(A-1) 사이의 턱을 직각으로 형성하고, 중간부(정착부(112)를 형성하는 위치)를 확장시킴으로써 정착부(112)를 형성한다.Subsequently, a jaw between the small diameter portion A-2 and the large diameter portion A-1 is formed at a right angle through a punch to form the fixing portion 112, and the intermediate portion (the fixing portion 112 is formed). ), The fixing unit 112 is formed.

이때, 너트(130)가 체결되는 대경부(A-1)의 단부를 작은 직경으로 형성할 수 있으며, 이는 하부 금형의 형상을 통해 정착부(112)의 단조시 함께 형성할 수 있다.At this time, the end portion of the large diameter portion (A-1) to which the nut 130 is fastened may be formed in a small diameter, which may be formed together when forging the fixing unit 112 through the shape of the lower mold.

(S40) 3차 단조.(S40) 3rd forging.

(S30) 공정을 거친 재료를 헤드부(111)의 형상을 갖는 상부 금형에 셋팅한 후 펀치로 두부를 타격하면 소경부가 헤드부(111)의 형상으로 형성된다.
(S30) When the material passed through the process is set in the upper mold having the shape of the head portion 111 and hit the head with a punch, the small diameter portion is formed in the shape of the head portion 111.

(S50) 체결부 형성.(S50) fastening portion formation.

(S10) 공정 내지 (S40) 공정을 통해서는 나사선이 없는 형태이며, 정착부(112) 저부에 나사선을 가공하여 체결부(113)를 형성함으로써 볼트부재(110)의 제조가 완료된다.Through the steps (S10) to (S40), there is no screw thread, and the bolt member 110 is completed by forming the fastening part 113 by machining the screw thread on the bottom of the fixing part 112.

본 실시예에 의한 앵커 볼트(100)의 시공은 다음과 같다.Construction of the anchor bolt 100 according to this embodiment is as follows.

볼트부재(110)의 확경 헤드부(111)에 확장 슬리브(120)를 결합한 후, 이 조립체를 콘크리트 기초(1)의 앵커공(2)에 삽입한다. 이때, 확장 슬리브(120)는 확장되지 않은 상태이기 때문에 앵커공(2)에 삽입시 간섭을 일으키지 않는다.After coupling the expansion sleeve 120 to the enlarged head portion 111 of the bolt member 110, the assembly is inserted into the anchor hole (2) of the concrete foundation (1). At this time, since the expansion sleeve 120 is not expanded, it does not cause interference when inserted into the anchor hole (2).

콘크리트 기초(1)에 설치 대상의 프레임(3)을 앵커공(2)에서 돌출된 볼트부재(110)의 체결부(113)에 끼우고 너트(130)를 체결한다. 너트(130)가 체결됨에 따라 볼트부재(110)가 앵커공(2)의 외부로 이동하면서 확장 슬리브(120)가 확장되어 앵커공(2)의 내벽에 정착된다. 또한, 볼트부재(110)의 정착부(112)는 앵커공(2)의 내벽에 밀착되어 볼트부재(110)의 요동을 방지함으로써 확장 슬리브(120)에 의한 확장을 자연스럽게 돕는다.
The frame 3 to be installed on the concrete foundation 1 is inserted into the fastening part 113 of the bolt member 110 protruding from the anchor hole 2 and fastens the nut 130. As the nut 130 is fastened, the bolt member 110 moves to the outside of the anchor hole 2, and the expansion sleeve 120 is expanded to be fixed to the inner wall of the anchor hole 2. In addition, the fixing unit 112 of the bolt member 110 is in close contact with the inner wall of the anchor hole 2 to prevent the rocking of the bolt member 110 to help the expansion by the expansion sleeve 120 naturally.

<실시예 2><Example 2>

도 3과 도 4에서 보이는 바와 같이, 본 실시예에 의한 앵커 볼트(100)는, 콘크리트 기초(1)에 형성된 앵커공(2)에 삽입되는 볼트부재(110), 볼트부재(110)의 둘레부에 결합되는 확장 슬리브(120), 확장 슬리브(120)를 강제로 확장시키는 너트(130) 및 볼트부재(110)의 둘레부에 결합되며 앵커공(2)에 정착되는 고정 슬리브(140)로 구성된다.3 and 4, the anchor bolt 100 according to the present embodiment, the bolt member 110 is inserted into the anchor hole 2 formed in the concrete foundation 1, the circumference of the bolt member 110 Expansion sleeve 120 coupled to the portion, the nut 130 for forcibly expanding the expansion sleeve 120 and the fixed sleeve 140 is coupled to the circumference of the bolt member 110 and fixed to the anchor hole (2) It is composed.

볼트부재(110), 확장 슬리브(120), 너트(130)는 전술한 실시예 1과 동일하며, 본 실시예는 고정 슬리브(140)가 앵커공(2) 내벽에 정착되어 확장 슬리브(120)와 함께 큰 정착력을 발생할 수 있는 특징이 있다.The bolt member 110, the expansion sleeve 120, and the nut 130 are the same as in the first embodiment, and in this embodiment, the fixing sleeve 140 is fixed to the inner wall of the anchor hole 2 to expand the expansion sleeve 120. In addition, there is a characteristic that can generate a large fixing force.

고정 슬리브(140)는 외주면에 요철부(141)가 형성된다.The fixing sleeve 140 has an uneven portion 141 formed on the outer circumferential surface thereof.

요철부(141)는 도면에서 보이는 것처럼, 내주면은 평평하면서 외주면이 산과 골이 반복된 구조일 수 있고, 다르게는 내주면과 외주면 모두가 산과 골이 반복되는 구조일 수도 있다.As shown in the drawing, the uneven portion 141 may be a structure in which the inner circumferential surface is flat and the outer circumferential surface is a mountain and a valley, or, alternatively, both the inner and outer circumference may be a structure in which the mountain and the valley are repeated.

너트(130)를 체결하면 볼트부재(110)의 이동에 의해 고정 슬리브(140)가 압축되며, 이때, 요철부(141)가 접히면서 확장되어 앵커공(2)에 정착된다. 즉, 고정 슬리브(140)가 볼트부재(110)의 요동을 막는 것뿐만 아니라 앵커공(2)에 정착됨으로써 확장 슬리브(120)에 의한 정착력 이상의 정착력을 발생한다.
When the nut 130 is fastened, the fixing sleeve 140 is compressed by the movement of the bolt member 110. At this time, the uneven portion 141 is folded and expanded to be fixed to the anchor hole 2. That is, the fixing sleeve 140 not only prevents the rocking of the bolt member 110 but also is fixed to the anchor hole 2 to generate fixing force greater than the fixing force by the expansion sleeve 120.

요철부(141)는 고정 슬리브(140)의 외주면에 전체적으로 형성되거나 일부분에 1개 이상(도면에는 2개가 일정 간격을 두고 형성된 것으로 도시됨)이 형성될 수 있다.
The uneven portion 141 may be formed on the outer circumferential surface of the fixed sleeve 140 as a whole, or one or more portions (shown as two formed at regular intervals in the drawing) may be formed.
