Abstract

PURPOSE: An anchor bolt fixable by nut fastening is provided to reduce working hours, to improve working condition and to reduce neglect accident since the fixing of an anchor bolt is possible with only nut fastening by the preventing of the no-load operation of an expanded pipe, a bolt and a reinforcing member. CONSTITUTION: An anchor bolt fixable by nut fastening comprises a bolt(110) and an expanded member(130). The bolt is inserted into the hole of a concrete structure. A screw(111) is formed on one side of the bolt and a wedge(112) is formed on the other side of the bolt. The expanded member comprises an expanded pipe(132), which can be expanded by a cutting part(131). A protrusion(140) is formed on the wedge of the bolt. Since the cutting part is blocked by the protrusion and the no-load operation of the expanded member is prevented in fastening a nut, the expanded member is expanded by only the fastening of the nut and is fixed to a concrete hole.

Description

너트조임에 의해 고정가능한 앵커볼트{Anchor bolt}Anchor bolt fixable by tightening nut {Anchor bolt}

본 발명은 앵커볼트에 관한 것으로, 더욱 상세하게는 앵커볼트를 콘크리트 벽체나 바닥, 천장 등에 고정함에 있어 타격을 가하지 않고 너트조임에 의해서 고정이 가능하도록 하기 위한 앵커볼트에 관한 것이다.The present invention relates to anchor bolts, and more particularly, to anchor bolts to be fixed by tightening nuts without applying a blow to fixing the anchor bolts to concrete walls, floors, ceilings and the like.

일반적으로 앵커볼트는 못이나 볼트 등 기타 체결수단들을 설치하기 곤란한 콘크리트 구조물 등에 부착물을 설치할 수 있도록 하기 위한 것으로, 원추형의 쐐기부와 나사부를 구비하는 볼트와, 상기 볼트의 외측에 끼워진 절개된 확관부를 구비하는 확관부재로 이루어진다.In general, the anchor bolt is to be able to install the attachment to a concrete structure, such as nails or bolts and other fastening means difficult to install, a bolt having a conical wedge portion and a screw portion, and the cut-out expansion portion fitted to the outside of the bolt It consists of an expansion member having a.

상기와 같은 앵커볼트의 결합방법은 콘크리트 구조물에 앵커볼트와 거의 동일한 직경의 구멍을 천공한 후, 상기 구멍에 앵커볼트를 억지끼움식으로 삽입하고 상기 확관부재를 타격구로 타격함으로써 확관부가 쐐기부의 외측면을 타고 오르면서 벌어지게 한다. 결국 상기 벌어진 확관부재의 직경이 콘크리트 구멍의 직경보다 더 커지게 되면서 앵커볼트는 콘크리트 구멍 속에 꽉 끼어 이탈되지 않게 되는 것 이다.As described above, the anchor bolt coupling method drills a hole having a diameter substantially the same as that of the anchor bolt in the concrete structure, and then inserts the anchor bolt into the hole by force fitting and hits the expansion member with a blow hole so that the expansion portion is wedge portion. Climb up as you climb the outside. As a result, the diameter of the expanded expansion member becomes larger than that of the concrete hole, so that the anchor bolt is tightly sandwiched in the concrete hole so as not to be separated.

이렇게 앵커볼트가 고정되면 와셔와 너트를 볼트에 끼워 조임으로써 작업이 완료되어 진다.When anchor bolt is fixed like this, work is completed by tightening washer and nut by bolt.

그러나 종래의 앵커볼트는 확관부재를 타격구로 타격하여야만 콘크리트 구멍 속에 고정될 수 있는 구조여서 타격에 의한 큰 소음이 발생하는 문제가 발생하고, 이로 인해 민원제기의 대상이 되는 등의 단점을 갖는다.However, the conventional anchor bolt is a structure that can be fixed in the concrete hole only by hitting the expansion member with the blow hole, so that a problem occurs that a large noise caused by the blow, which is a target of the complaint complaints.

또 작업자가 타격함에 있어 두 손을 사용하여야 하므로 안정적인 몸의 지탱이 곤란하고, 타격시 손을 때리거나 공구의 튀어오름 등의 현상으로 항상 안전사고의 우려가 큰 단점을 갖는 것이다.In addition, it is difficult to support a stable body because the worker has to use both hands when hitting, and there is always a risk of a safety accident due to the phenomenon such as hitting a hand or jumping of a tool when hitting.

또한 종래의 앵커볼트는 타격에 의한 고정 후에 다시 너트로 조이는 이중작업을 하므로 작업시간이 길어지는 단점을 갖는다.In addition, the conventional anchor bolt has a disadvantage that the work time is long because the double work is tightened again with a nut after fixing by hitting.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 본 발명은 볼트의 쐐기부에는 걸림돌기를 형성하고 상기 걸림돌기에 확관부재의 절개부가 걸려서 확관부재의 헛돎을 방지하도록 함으로써 볼트에 나사결합되는 너트의 조임만으로도 확관부재가 확관되도록 하여 콘크리트 구멍 속에 고정가능하도록 하 는 너트조임에 의해 고정가능한 앵커볼트를 제공하는 데 그 목적이 있다.Therefore, the present invention has been made to solve the above problems, the present invention is to form a locking projection on the wedge of the bolt and screwed to the bolt by preventing the waste of the expansion member is caught by the cutout of the expansion member to the locking projection The purpose of the present invention is to provide an anchor bolt that can be fixed by tightening a nut that allows the expansion member to be expanded by tightening the nut so that the expansion member can be fixed in the concrete hole.

또한, 본 발명은 상기 걸림돌기를 구비하는 볼트와 확관부재 사이에 경사돌기를 구비하는 결합보강부재를 형성하되, 상기 결합보강부재의 일측에도 삽입홈을 형성하여 상기 삽입홈이 볼트의 걸림돌기에 걸려 헛돎을 방지하면서 경사돌기가 확관부재의 통공을 통해 확관부재 밖으로 돌출되면서 콘크리트 구멍 내벽에 박히도록 하여 고정되도록 하는 너트조임에 의해 고정가능한 앵커볼트를 제공하는 데 그 목적이 있다.In addition, the present invention forms a coupling reinforcing member having an inclined protrusion between the bolt and the expansion member having the locking projection, the insertion groove is formed on one side of the coupling reinforcing member, the insertion groove is caught in the locking projection of the bolt It is an object of the present invention to provide an anchor bolt that can be fixed by tightening a nut to be fixed while being inclined to be projected out of the expansion member through the through-hole of the expansion member while being prevented.

또한, 본 발명은 상기 쐐기부의 끝단 가장자리에 일정간격으로 돌출된 볼트헛돎방지돌기를 형성함으로써 너트조임에 의해 고정가능한 앵커볼트를 제공하는 데 그 목적이 있다.In addition, an object of the present invention is to provide an anchor bolt that can be fixed by tightening a nut by forming a bolt bolt prevention protrusion protruding at a predetermined interval on the end edge of the wedge portion.

이처럼 본 발명은 확관부재와 볼트, 결합보강부재의 헛돎을 방지함으로써 너트조임만으로도 앵커볼트의 고정이 가능하게 되어 작업시간의 단축, 작업환경의 개선, 안전사고를 줄일 수 있는 매우 유용한 발명인 것이다.Thus, the present invention is a very useful invention that can be fixed by anchor bolts only by tightening the nut by preventing the waste of the expansion member and bolt, the coupling reinforcing member to shorten the working time, improve the working environment, safety accidents.

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.

본 발명에 따른 너트조임에 의해 고정이 가능한 앵커볼트(100)는 콘크리트 구조물(A)의 구멍에 끼워져 결합되며, 일측에 나사부(111)와 타측에 쐐기부(112)를 구비하는 볼트(110)와, 일측에 절개부(131)에 의해 확관이 가능한 확관부(132)를 구비하는 확관부재(130)로 구성된 앵커볼트에 있어서, 상기 볼트(110)의 쐐기부(112)에는 걸림돌기(140)를 형성하고, 상기 걸림돌기(140)에 확관부재(130)의 절개부(131)가 걸려서 확관부재(130)의 헛돎을 방지하도록 함으로써 볼트(110)에 나사결합되는 너트(B)의 조임만으로도 확관부재(130)가 확관되도록 하여 콘크리트 구멍 속에 고정가능하도록 구성되어 진다.Anchor bolt 100 that can be fixed by tightening the nut according to the present invention is fitted into the hole of the concrete structure (A) is coupled, the bolt 110 having a threaded portion 111 and the wedge portion 112 on one side. And, in the anchor bolt consisting of an expansion member 130 having an expansion pipe 132 which can be expanded by the incision 131 on one side, the wedge portion 112 of the bolt 110, the locking projection 140 ) And tightening of the nut (B) screwed to the bolt (110) by preventing the bulge of the expansion member 130 is caught by the cutout 131 of the expansion member 130 to the locking projection 140. Only by expanding the expansion member 130 is configured to be fixed in the concrete hole.

또 상기 걸림돌기(140)를 구비하는 볼트(110)와 확관부재(130) 사이에 경사돌기(121)를 구비하는 결합보강부재(120)를 형성하되, 상기 결합보강부재(120)의 일측에도 삽입홈(125)을 형성하여 상기 삽입홈(125)이 볼트(110)의 걸림돌기(140)에 걸려 헛돎을 방지하면서 경사돌기(121)가 확관부재(130)의 통공(133)을 통해 확관부재(130) 밖으로 돌출되면서 콘크리트 구멍 내벽에 박히도록 하여 고정되도록 구성된다.In addition, a coupling reinforcing member 120 having an inclined protrusion 121 is formed between the bolt 110 having the locking protrusion 140 and the expansion member 130, and on one side of the coupling reinforcing member 120. The inclined protrusion 121 is expanded through the through hole 133 of the expansion member 130 while the insertion groove 125 forms the insertion groove 125 to prevent the waste from being caught by the locking protrusion 140 of the bolt 110. The member 130 is configured to be fixed by being projected out of the concrete hole inner wall.

이때 상기 결합보강부재(120)의 삽입홈(125)은 보통 2~4개로 형성되는데, 이때 상기 삽입홈(125)은 경사돌기(121)와 동일한 일직선상에 위치하게 된다.At this time, the insertion groove 125 of the coupling reinforcing member 120 is usually formed of 2 to 4, wherein the insertion groove 125 is positioned on the same line as the inclined protrusion 121.

즉 콘크리트 구조물(A)의 구멍에 앵커볼트(100)를 밀어 넣은 후, 너트(B)로 조이는 경우 상기 결합보강부재(120)의 경사돌기(121)가 확관부재(130)의 절개부(131)에 안내되어 상기 절개부(131)의 일단에 형성된 통공(133)의 경사면(134)을 타고 구멍 내벽에 박히도록 상기 삽입홈(125)과 절개부(131)는 동일선상에 위치하게 되며, 이로 인해 상기 볼트(110)의 쐐기부(112)에 돌출형성된 걸림돌기(140)는 상기 삽입홈(125)과 절개부(131)에 자리를 잡게 되는 것이다.That is, when the anchor bolt 100 is pushed into the hole of the concrete structure A, the inclined protrusion 121 of the coupling reinforcing member 120 is cut off 131 of the expansion member 130 when tightened with the nut B. The insertion groove 125 and the cutout 131 are positioned on the same line so as to be guided to the inner wall of the hole through the inclined surface 134 of the through hole 133 formed at one end of the cutout 131. As a result, the locking protrusion 140 protruding from the wedge portion 112 of the bolt 110 is positioned in the insertion groove 125 and the cutout portion 131.

이처럼 볼트(110)의 나사부(111)에 너트(B)를 체결하여 조이는 경우, 확관부재(130)는 점차 뒤로 밀리게 되고, 따라서 통공(133)의 경사면(134)에 얹어져 있던 결합보강부재(120)의 경사돌기(121)는 점차 벌어지면서 확관부재(130) 밖으로 돌출되어진다.As such, when tightening and tightening the nut B to the threaded portion 111 of the bolt 110, the expansion member 130 is gradually pushed back, so that the coupling reinforcement member that was placed on the inclined surface 134 of the through hole 133 Inclined projection 121 of 120 is gradually extended to protrude out of the expansion member 130.

결국 이렇게 돌출된 경사돌기(121)는 콘크리트 구멍 내벽에 박히게 되어 확관부재(130)와 결합보강부재(120)는 헛돌지 않게 되고, 결국 볼트(110)는 걸림돌기(140)에 의해 확관부재(130)와 결합보강부재(120)에 걸리게 되어 헛돌지 않게 된다. 이처럼 볼트(110)의 걸림돌기(140)는 확관부재(130)와 결합보강부재(120)의 헛돎을 방지하면서, 동시에 확관부재(130)와 결합보강부재(120)에 의해 볼트(110)가 헛도는 것도 방지하는 구성이다.As a result, the inclined protrusion 121 protruded is embedded in the inner wall of the concrete hole, so that the expansion pipe member 130 and the coupling reinforcing member 120 are not in vain, and the bolt 110 is expanded by the locking protrusion 140. 130) and is coupled to the reinforcing member 120 is not in vain. As such, the locking protrusion 140 of the bolt 110 prevents waste of the expansion member 130 and the coupling reinforcing member 120, and at the same time, the bolt 110 is formed by the expansion member 130 and the coupling reinforcing member 120. It is the structure which prevents a waste.

이로 인해 본 발명은 너트(B)의 조임만으로도 콘크리트 구멍 속에 본 발명 앵커볼트(100)를 고정시킬 수 있는 것이다.For this reason, the present invention can fix the present invention anchor bolt 100 in the concrete hole only by tightening the nut (B).

대개 앵커볼트(100)가 삽입되어 고정되는 콘크리트 구멍은 앵커볼트(100)의 직경과 거의 차이가 없이 뚫게 되고, 또 시멘트 가루 등에 의해 앵커볼트(100)가 한번 삽입되면 그 안에서 쉬 헛돌지 않는다.In general, the anchor bolt 100 is inserted into the concrete hole is fixed is almost no difference with the diameter of the anchor bolt 100, and once the anchor bolt 100 is inserted by cement powder or the like does not easily turn in it.

그러나 본 발명은 콘크리트 구멍 안에서 혹시라도 모르는 볼트(110)의 헛돎을 방지하기 위해 상기 쐐기부(112)의 끝단 가장자리에 일정간격으로 돌출된 볼트헛돎방지돌기(150)를 형성할 수도 있다. 상기 볼트헛돎방지돌기(150)는 콘크리트 구멍에 앵커볼트(100)가 삽입되면 내벽에 길이방향의 미세한 홈을 내면서 박히는 구조여서 볼트(110)가 구멍 속에서 헛도는 것을 방지할 수 있게 된다.However, in the present invention, in order to prevent any misunderstanding of the bolt 110 in the concrete hole, the bolt misalignment prevention protrusion 150 protruding at a predetermined interval may be formed at the end edge of the wedge 112. When the bolt bolt prevention protrusion 150 is inserted into the concrete hole while the anchor bolt 100 is inserted into the inner wall while making a fine groove in the longitudinal direction to prevent the bolt 110 is lost in the hole.

또한, 본 발명은 상기 걸림돌기(140)를 삽입홈(125)에만 위치하도록 돌출형성하고, 상기 삽입홈(125)의 상부에 연장·돌출된 안내돌기(126)를 형성하되, 상기 안내돌기(126)는 확관부재(130)의 절개부(131)에 안내되도록 구성할 수 있다.In addition, the present invention is formed so as to project the locking projection 140 is located only in the insertion groove 125, to form a guide protrusion 126 extending and protruded on the upper portion of the insertion groove 125, the guide projection ( 126 may be configured to be guided to the cutout 131 of the expansion member (130).

즉 상기 안내돌기(126)는 볼트(110)가 콘크리트 구조물(A)의 구멍에서 헛도는 것을 방지할 뿐더러 상기 볼트(110)를 너트(B)로 조여 구멍에 결합하는 경우, 상기 확관부재(130)와 함께 결합보강부재(120)도 쐐기부(112)에 의해 확관, 즉 방사상으로 벌어져 구멍에 박히게 되는데, 이때 상기 안내돌기(126)의 끝단도 상방으로 들려 구멍 내벽에 박히게 되므로 본 발명 앵커볼트(100)는 더욱 견고하게 고정되는 것이다.That is, the guide protrusion 126 not only prevents the bolt 110 from screwing in the hole of the concrete structure A, but also tightens the bolt 110 with the nut B to be coupled to the hole. 130, together with the reinforcing reinforcing member 120 is also widened by the wedge portion 112, that is, the radially open and become lodged in the hole, the end of the guide projection 126 is also lifted upwards to be lodged in the inner wall of the anchor anchor of the present invention The bolt 100 is more firmly fixed.
