일반적으로 셋트 앵커볼트는 콘크리트 바닥이나 또는 벽체에 매설구멍을 형성하고 그 매설구멍에 원추형의 확관너트가 결합되어 있는 나사봉이 끼워진 설치관을 투입하여 설치관의 하부에서 원추형의 확관너트를 나사봉으로 나사조임하는 방식에 의해 확관너트가 설치관의 하부 확관부를 확관시켜 확관부가 매설구멍에 밀착 고정되는 수단으로 설치관이 매설구멍에 나사봉이 고정 설치되도록 한 다음 외부로 돌출된 나사봉에 간판과 같은 부착물을 체결하게 된다.In general, a set anchor bolt forms a buried hole in a concrete floor or wall, and a screw rod fitted with a conical expansion nut is inserted into the buried hole, and a conical expansion nut of a conical pipe nut is installed at a lower part of the installation pipe. By means of screw tightening, the expansion nut expands the lower expansion part of the installation pipe so that the expansion pipe is tightly fixed to the buried hole so that the installation pipe can be fixed to the buried hole. The attachment will be fastened.

그러나 상기의 설치관은 하부 확관부만이 매설구멍의 일측에 밀착고정되므로 설치관의 고정상태가 약하여 부착물 설치 후 설치관이 유동되거나 분리 될 우려가 있는 등 이에 따른 신뢰도가 떨어지는 문제점이 있었다.However, the installation pipe has a problem that the reliability of the installation pipe is lowered because only the lower expansion pipe is fixed in close contact with one side of the buried hole.

본 고안은 이러한 문제점을 해결하기 위하여 설치관의 상·하부에 각각 확관부를 형성하여 나사봉의 몸체상부에 형성된 확관돌부 및 나사봉 하부에 나사결합되는 원추형의 확관너트에 의해 설치관 상·하부의 확관부가 매설구멍 내의 양측에 확관되어 밀착고정되게 한 수단으로 매설구멍에 투입되는 설치관이 안정적으로 견고한 고정상태를 유지할 수 있도록 한 셋트 앵커볼트를 제공함에 있다.In order to solve this problem, the present invention forms an expansion pipe at the upper and lower portions of the installation pipe, respectively, so that the expansion pipe protrusion formed at the upper portion of the body of the screw rod and the conical expansion nut screwed to the lower portion of the screw rod are installed in the upper and lower portions of the installation pipe. It is to provide a set anchor bolt to ensure that the installation pipe which is introduced into the buried hole by the means that the expansion pipe is expanded to both sides in the buried hole to maintain a stable and stable fixed state.

본 고안의 셋트 앵커볼트는 콘크리트 바닥이나 벽면에 형성되는 매설구멍에 투입되는 제1확관부가 형성되고 설치관의 상부는 외주면을 가압하여 내향된 환턱을 이루는 제2확관부가 형성되며, The set anchor bolt of the present invention is formed with a first expansion pipe is inserted into the buried hole formed in the concrete floor or wall surface and the upper portion of the installation pipe is formed with a second expansion pipe forming an inward inward pressure by pressing the outer peripheral surface,

상기 설치관에 관통상태로 끼워지는 나사봉의 하부에 원추형의 확관너트가 나사결합되어 제1확관부를 확관하게되고, 나사봉의 상부몸체에 확관돌부가 형성되어 제2확관부를 고정설치되고 나사봉의 상단돌출부에 부착물이 너트결합으로 체결되도록한 것을 특징으로 한다.A conical tube nut is screwed into the lower part of the screw rod inserted through the installation tube to expand the first expansion tube, and an expansion tube protrusion is formed on the upper body of the screw rod to fix and install the second expansion tube. The upper projection is characterized in that the attachment is fastened by the nut coupling.

이하 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

콘크리트에 형성된 매설구멍(40)에 투입되는 설치관(10)의 하부는 등간격으로 다수 절개된 제1확관부(12)가 형성되고, 제1확관부(12)의 일측 절개부분에 삽지홈(16)이 형성되어 나사봉(20)에 결합되는 확관너트(22)의 걸림돌기(22a)가 삽지안내 되게하며, 설치관(10)의 상부는 외주면을 내측으로 가압하여 내주벽이 내향 돌 출된 환턱으로 된 제2확관부(14)가 형성된다.The lower part of the installation pipe 10 which is inserted into the buried hole 40 formed in the concrete is formed with a plurality of first incisions 12 are cut at equal intervals, the insertion groove in one incision of the first expansion pipe 12 (16) is formed so that the engaging projection 22a of the expansion nut 22 coupled to the screw rod 20 is guided insertion, and the upper portion of the installation pipe 10 presses the outer circumferential surface inward so that the inner circumferential wall is inward stone. A second expanding portion 14 is formed with the exit ring.

상기 나사봉(20)의 하부는 원추형으로 확관너트(22)가 나사결합되고 그 확관너트(22) 일측에 걸림돌기(22a)가 형성되어 상기 삽지홈(16) 내에 끼워져서 걸림작용을 하게되며, 나사봉(20)의 상부몸체에 나사봉의 둘레를 감싸는 확관돌부(24)가 형성되고 확관돌부(24) 상부에 받침단턱(24a)이 형성되어 나사봉(20) 상부에 체결하는 너트(26)의 나사이동을 방지하는 역할을 하고 확관돌부(24) 하부는 경사단턱(24b)이 형성되어 제2확관부(14)에 받쳐지거나 하향진입할 수 있게 하는 역할을 한다.The lower portion of the screw rod 20 is conical in the expansion nut 22 is screwed and the engaging projection 22a is formed on one side of the expansion nut 22 is inserted into the insertion groove 16 to engage the action. The expansion pipe 24 is formed on the upper body of the screw rod 20 to surround the screw rod. A support step 24a is formed at the upper portion of the expansion pipe 24 to fasten the nut 26 to the upper portion of the screw rod 20. ) And prevents the screw movement of the lower part of the expansion pipe 24, the inclined stepped portion (24b) is formed to support the second expansion pipe 14 or to allow the downward entry.

상기와 같은 구성의 설치관(10) 내에 나사봉(20)이 관통상태로 끼워지되 설치관(10) 하부의 제1확관부(12)는 나사봉(20)에 결합된 확관너트(22)로 확관시키고 설치관(10) 상부의 제2확관부(14)는 나사봉(20)의 상부의 확관돌부(24)에 의해 확관되는 구성으로 되어 있다.The screw rod 20 is inserted into the installation pipe 10 having the above configuration, but the first expansion pipe portion 12 below the installation pipe 10 has an expansion nut 22 coupled to the screw rod 20. The 2nd expansion part 14 of the installation pipe 10 upper part is expanded by the expansion pipe protrusion 24 of the upper part of the screw rod 20, and is expanded.

상기 나사봉(20)의 상단부에 와셔(28) 및 부착물(30)을 끼워 너트(26)결합으로 체결하게 된다.The washer 28 and the attachment 30 are fitted to the upper end of the screw rod 20 to be fastened by the nut 26.

또, 상기 너트(26)는 도 7과 같이 너트(16) 외측에 커버(26a)가 형성되어 나사봉(20) 단부가 노출되지 않고 외관이 미려하게 할 수 있도록 한 것을 더 포함할 수 있다.In addition, the nut 26 may further include a cover 26a formed outside the nut 16 as shown in FIG. 7 so that the end of the screw rod 20 may not be exposed and the appearance may be beautiful.

이와 같이 된 본 고안은 도 4와 같이 설치관(10)에 나사봉(20)이 관통상태로 끼워지고 나사봉(20) 하부에 확관너트(22)가 결합되어 있는 셋트 앵커볼트를 콘크리트에 형성한 매설구멍(40)에 투입한 다음 나사봉(20) 상단에 돌출된 확관돌 부(24) 외측에 장착물(30)을 끼우고 확관돌부(24) 상부 받침단턱(24a)에 와셔(28)가 받쳐지도록 한 상태에서 너트(26)를 결합하여 긴밀히 체결한다.The present invention as described above forms a set anchor bolt in the concrete that the screw rod 20 is inserted into the installation pipe 10 in the penetrating state and the expansion nut 22 is coupled to the lower screw rod 20 as shown in FIG. After inserting into one of the buried holes 40, insert the fitting 30 on the outside of the expansion pipe portion 24 protruding from the top of the screw rod 20, washer (28) in the upper support step 24a of the expansion pipe protrusion 24 ) And tightly tighten the nut (26) in the support state.

이어서 도 5와 같이 받침단턱(24a)에 의해 더이상 나사이동되지 않고 고정된 상태의 너트(26)를 체결방향으로 계속 돌리게 되면 나사봉(20)이 회동함과 아울러 확관돌부(24) 하부의 경사단턱(24b)이 설치관(10)의 제1확관부(12)에 받쳐진 상태로 공회전 되면서 나사봉(20) 하부에 결합된 확관너트(22)가 나사이동하는 상승에 의해 제1확관부(12)를 외측으로 밀어내는 확관작용으로 매설구멍(40) 하부는 제1확관부(12)로 긴밀히 밀착고정된다.Subsequently, as shown in FIG. 5, when the nut 26 in the fixed state is no longer moved by the support step 24a and continues to be turned in the fastening direction, the screw rod 20 is rotated and the bottom of the expansion pipe 24 is inclined. As the stepped portion 24b is idly rotated while being supported by the first expansion portion 12 of the installation pipe 10, the expansion pipe nut 22 coupled to the lower portion of the screw rod 20 is screwed to move the first expansion pipe portion. The lower part of the embedding hole 40 is tightly fixed to the first expansion tube 12 by the expansion action of pushing (12) outward.

상기와 같이 설치관(10)의 제1확관부(12)가 매설구멍(40) 하부에 확관되어 더이상 확관진행이 중단됨과 아울러 확관너트(22)의 이동이 멈춰진 상태에서도 도 6과같이 너트(26)를 체결방향으로 계속 돌리게 되면 이와 연동되어 회동이 되는 나사봉(20)은 이동이 멈춰진 확관너트(22)의 나사부를 따라 나사봉(20)이 하부방향으로 나사이동하려는 힘이 발생하게되고 이러한 나사봉(20)이 너트(26)와 함께 결합된 와셔(28)가 장착물(30)을 밀착고정 할 때까지 하부이동에 의해 설치관(10)의 제2확관부(14)에 받쳐진 나사봉(20)의 확관돌부(24)가 경사단턱(24b)을 따라 하향 진입하여 확관돌부(24)의 가압력에 의해 설치관(10)에 내향돌출 환턱으로 형성된 제2확관부(14)를 외측으로 밀어내는 확관작용으로 매설구멍(40) 상부를 제2확관부(14)로 긴밀히 고정하게 된다.As described above, the first expansion part 12 of the installation pipe 10 is extended to the lower part of the buried hole 40 so that expansion of the expansion pipe is no longer stopped and the movement of the expansion nut 22 is stopped, as shown in FIG. 6. 26) If the screw rod 20 is continuously rotated in the fastening direction, the screw rod 20 that is rotated in conjunction with the screw rod 20 generates a force to move the screw rod 20 downward along the threaded portion of the expansion nut 22 where the movement stops. The screw rod 20 is supported by the second expansion portion 14 of the installation pipe 10 by moving downward until the washer 28 coupled with the nut 26 secures the attachment 30. The second expansion pipe portion 14 formed as an inwardly projecting round projection in the installation pipe 10 by the pressing force of the expansion pipe protrusion 24 is pushed downward along the inclined stepped portion 24b of the screw rod 20. The upper part of the buried hole 40 is tightly fixed to the second expansion part 14 by the expansion action of pushing the outwardly.

즉, 본 고안의 설치관(10)에 형성된 제1확관부(12) 및 제2확관부(14)가 매설구멍(40)의 상·하부 양측에 각각 밀착고정되는 수단으로 견고한 고정상태를 유지 할 수 있게 된다.That is, the first expansion part 12 and the second expansion part 14 formed in the installation pipe 10 of the present invention are firmly fixed to each of the upper and lower sides of the buried hole 40 to maintain a firm fixed state. You can do it.

상기에서 설명한 바와 같이 설치관(10)에 형성된 제1확관부(12)와 제2확관부(14)는 순차적으로 확관작용이 이루어질 수 있고 또는 동시에 확관작용이 이루어질 수 있는 것이므로 이를 본 고안에서는 한정하지 않는다.As described above, the first expansion unit 12 and the second expansion unit 14 formed in the installation pipe 10 may be expanded in sequence or may be expanded at the same time, which is limited in the present invention. I never do that.

이상에서 본 고안은 상기 실시예를 참고하여 설명하였지만 본 고안의 기술사상 범위내에서 다양한 변형실시가 가능함은 물론이다.Although the present invention has been described with reference to the above embodiment, various modifications can be made within the technical spirit of the present invention.

이와 같이 된 본 고안의 셋트 앵커볼트는 콘크리트 형성된 매설구멍에 투입되는 확관부가 형성되어 매설구멍 내의 상·하부 양측에 각각 확관되어 밀착고정하게 되므로 보다 안정적이고 견고한 고정상태를 유지할 수 있는 이점이 있다.The set anchor bolt according to the present invention has an advantage of maintaining a more stable and stable fixed state because expansion anchors are inserted into concrete-embedded holes and are expanded and fixed to each of the upper and lower sides of the buried holes. .
