Description
본 고안은 셋트 앙카볼트의 개량 고안에 관한 것으로서, 보다 구체적으로는 한 셋트의 앙카볼트를 구성하는 각 부속들의 결합을 보다 용이하게 할 뿐 만 아니라, 앙카볼트의 설치시 설치관과 확관너트간의 미끄러짐을 방지하여 앙카볼트의 설치가 보다 견고하고 신속하게 이루어질 수 있도록 한 것이다.The present invention relates to an improved design of a set anchor bolt, and more specifically, to facilitate the coupling of the parts constituting a set of anchor bolts, as well as to slip between the installation pipe and the expansion nut when installing the anchor bolt. By preventing the installation of anchor bolts to be made more robust and faster.
일반적으로 셋트 앙카볼트란 첨부도면 도 5와 같이 콘크리트 바닥이나 또는 벽체에 앙카 설치공(40)을 형성한 후 이 설치공(40)에 설치관(10')을 끼운 볼트(20')를 거꾸로 투입하여 지상으로 노출된 볼트(20')의 나사부(202')에 고정할 피고정체(50)의 결합부를 끼운 후 외부로 노출된 볼트(20')의 나사부(202')에 너트(30')를 체결하게되면, 너트(30')를 조임에 따라서 볼트(20')가 지상으로 인출되면서, 원추형으로 된 볼트(20')의 머리부분이 설치관(10')의 하단부에 형성된 확관부(10a')를 확관시킴으로서, 설치공(40) 내부의 설치관(10')이 확관되면서 고정되어 피고정체(50)의 고정이 이루어지게 하는 것이다.In general, the set anchor bolt is attached to the anchor hole (40) on the concrete floor or wall as shown in Figure 5, and then the mounting hole (40 ') to the mounting pipe (10') inverted bolt 20 ' Insert the coupling portion of the fixed body 50 to be inserted into the screw portion 202 'of the bolt 20' exposed to the ground, and then attach the nut 30 'to the threaded portion 202' of the bolt 20 'exposed to the outside. When tightening the nut 30 ', the bolt 20' is pulled out to the ground as the nut 30 'is tightened, and the expansion part formed at the lower end of the installation pipe 10' with the head of the bolt 20 'made of a conical shape. By expanding the 10a ', the installation pipe 10' inside the installation hole 40 is fixed while being secured so that the fixed body 50 is fixed.
그러나 상기와 같은 종래의 셋트 앙카볼트는 설치관에 끼워지는 볼트의 머리부분을 원추형으로 형성하여 이를 설치공에 내부로 투입하므로서 볼트의 나사부분이 설치공 외부로 돌출되기때문에, 피고정체를 고정하기 위하여 볼트에 너트를 체결하게되면, 볼트의 나사부가 외부로 노출되어 미관상 보기가 좋지 않고 외부 영향으로 인해 볼트의 나사부에 형성된 나사산이 손상될 경우에는 너트를 다시 풀기가 어렵기 때문에 피고정체의 이동이나 교체를 위해서 앙카볼트를 해체하기가 매우 힘든 문제점이 있었다.However, the conventional set anchor bolt as described above forms the head portion of the bolt that is fitted to the installation pipe into a conical shape and inserts it into the installation hole, so that the screw portion of the bolt protrudes out of the installation hole, thereby fixing the fixed body. In order to fasten the nut to the bolt, the screw part of the bolt is exposed to the outside, so it is difficult to see aesthetically, and if the thread formed on the screw part of the bolt is damaged due to external influence, it is difficult to loosen the nut again. It was very difficult to dismantle the anchor bolt for replacement.
또한, 피고정체의 고정부 외부에서 너트를 조였을때, 설치관과 원추형의 볼트 머리부분에 미끄러짐이 발생하여 너트와 볼트가 같이 회전하게되면, 너트를 회전시킴에도 불구하고 볼트가 조여지지 않아서 볼트에 의한 설치관의 확관이 이루어지지 못하는 문제점등이 있었다.In addition, when the nut is tightened from the outside of the fixed part of the fixed body, when the nut and the bolt are rotated together due to slippage between the mounting tube and the conical bolt head, the bolt is not tightened even though the nut is rotated. There was a problem that can not be expanded by the installation pipe.
그리하여 최근에는 볼트와 너트의 위치가 반대로 되어 설치관의 상부에서 볼트가 끼워지고, 하부에는 확관너트를 구비하여 확관너트에 의해 설치관의 확관부가 확관되게 하는 셋트 앙카볼트가 개발되어 상용화되고 있으며, 본원 출원인 역시 이러한 앙카볼트의 개량 고안을 출원하여 실용신안 등록 제241919호로 등록 받은 바 있다.Therefore, recently, a set anchor bolt has been developed and commercialized, in which the bolt and nut are reversed and the bolt is fitted at the upper part of the installation pipe, and the expansion nut is provided at the lower part so that the expansion part of the installation pipe is expanded by the expansion nut. In addition, the applicant of the present application has also been applied for such an improved design of the anchor bolt and registered as Utility Model Registration No. 241919.
그러나, 위와 같은 셋트 앙카볼트의 개량 고안들은 확관너트와 설치관간의 미끄러짐을 방지하기 위하여 요철면을 형성하거나 또는 설치관에 장홈을 형성하고 확관너트에는 돌기를 형성하여 설치관에 확관너트를 끼워서 결합하는 방식 등이 적용되었으나, 전자와 같이 요철면을 형성하는 경우에는 미끄럼을 방지하는 효과가 부족하였으며 후자와 같이 설치관에 형성된 장홈과 확관너트에 형성된 돌기를 이용해 확관너트를 설치관에 결합하는 경우에는 설치관이 자체의 강도로 인해 신축성이부족하기 때문에, 설치관의 장공에 확관너트의 돌기를 결합하기 위해서는 일단 설치관의 확관부를 강제로 확관시킨 후 확관너트의 돌기를 설치관의 장공에 끼우고, 다시 확관부를 수축시켜야 하기 때문에 생산과정에서 생산능률이 다소 떨어지는 문제점이 있었다.However, the improved designs of the above set anchor bolts form an uneven surface to prevent slippage between the expansion nut and the installation pipe, or form a long groove in the installation pipe and form a protrusion in the expansion nut to insert the expansion nut into the installation pipe. In the case of forming the uneven surface like the former, the effect of preventing slipping is insufficient, and when the expansion nut is combined with the installation pipe by using the long groove formed in the installation pipe and the protrusion formed in the expansion nut as in the latter Since the installation pipe lacks elasticity due to its strength, in order to combine the projection of the expansion nut into the hole of the installation pipe, the expansion pipe of the installation nut is forced to expand first, and then the projection of the expansion nut is There was a problem in that the production efficiency was somewhat lowered during the production process because it had to be fitted .
본 고안은 상기와 같은 종래의 문제점을 해소하기 위하여 안출한 것으로서, 설치관의 하단부에는 하향으로 돌출된 다수의 걸림편을 형성하고, 확관너트의 외주면에는 설치관에 형성된 걸림편이 끼워지는 걸림홈부를 형성하여 앙카볼트 셋트의 결합이 보다 용이하게 함과 동시에, 앙카볼트의 설치시에 확관너트와 설치관간의 미끄러짐을 확실하게 방지할 수 있게 한 것으로서 이를 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.The present invention has been made in order to solve the conventional problems as described above, the lower end of the installation pipe to form a plurality of locking pieces protruding downward, the locking groove portion is fitted into the locking piece formed in the installation pipe on the outer peripheral surface of the expansion nut Forming the anchor bolt set more easily and at the same time, it is possible to reliably prevent the slip between the expansion nut and the installation pipe when installing the anchor bolt as described in more detail by the accompanying drawings as follows. .

In the conventional set anchor bolt configured to fasten the expansion nut 30 to the threaded portion 202 of the
설치관(10)의 확관부(10a)에는 하향으로 돌출 되어 탄력성을 가지며, 하단부에 걸림턱(104a)을 형성한 다 수개의 걸림편(104)을 형성하고,The expansion pipe portion 10a of the installation pipe 10 has downward elasticity and has a plurality of locking pieces 104 having a locking jaw 104a at the lower end thereof.
확관너트(30)의 외주면에는 설치관(10)에 형성된 걸림편(104)이 끼워지는 걸림홈부(302)를 형성한 구조이다.On the outer circumferential surface of the expansion pipe nut 30, a locking groove 302 into which the locking piece 104 formed in the installation pipe 10 is fitted is formed.
이와 같이 된 본 고안은 설치관(10)에 확관너트(30)를 결합하기가 용이하여 셋트 앙카볼트의 결합이 보다 수월하게 이루어질 뿐 만 아니라, 설치관(10)의 걸림편(104)과 확관너트(30)의 걸림홈부(302)에 의해 결합이 견고하게 이루어지기 때문에, 셋트 앙카볼트의 설치를 위해 볼트(20)를 회전시키는 과정에서 확관너트(30)와 설치관(10)간의 미끄러짐을 방지하여 앙카볼트의 신속하고 견고한 설치가 이루어질 수 있게 되는데, 이러한 본 고안 바람직한 실시예를 첨부도면에 의하여 설명하면 다음과 같다.The present invention, as described above, is easy to combine the expansion nut 30 to the installation pipe 10, the coupling of the set anchor bolt is made easier, as well as the locking piece 104 and expansion pipe of the installation pipe 10 Since the coupling is secured by the locking groove 302 of the nut 30, the sliding between the expansion nut 30 and the installation pipe 10 is prevented in the process of rotating the bolt 20 for installation of the set anchor bolt. It is possible to prevent the fast and secure installation of the anchor bolt, it will be described by the accompanying drawings a preferred embodiment of the present invention as follows.
먼저 첨부도면 도 1은 본 고안의 사시도로서, 도면에서와 같이 설치관(10)에는 하단에서 상향으로 절개부(102)를 형성한 확관부(10a)를 형성하되, 각 절개부(102) 사이에는 하향으로 돌출 되게 다수의 걸림편(104)이 형성된다.1 is a perspective view of the present invention, as shown in the installation pipe 10 to form an expansion tube (10a) formed in the incision 102 from the bottom upward, but between each incision 102 A plurality of engaging pieces 104 are formed to protrude downward.
이러한 걸림편(104)은 설치관(10)을 제조할 때, 설치관(10)의 외벽을 잘라내서 형성하거나 또는 걸림편(104) 부분만을 별도 제작하여 이를 설치관(10)의 저면에 용착하게 되는데, 구체적인 생산방법은 제품의 생산단가에 따라 다양하게 변경될 수 있으므로 이에 대한 구체적인 설명은 생략한다.When the catching piece 104 is manufactured by installing the installation pipe 10, it is formed by cutting the outer wall of the installation pipe 10, or by manufacturing only the portion of the catching piece 104 to be welded to the bottom surface of the installation pipe (10) The specific production method may be variously changed according to the production cost of the product, and thus a detailed description thereof will be omitted.
한편, 설치관(10)의 확관부(10a) 하단에 형성된 걸림편(104)은 그 형태가 가늘고 긴 막대형상으로 이루어져 있어서, 설치관(10)과 동일한 재질로 일체화되어있더라도 어느 정도의 탄력성을 발휘할 수 있기 때문에 원추형으로 된 확관너트(30)를 설치관(10)의 확관부(10a)에 억지끼움하는 경우에는 걸림편(104)이 외향으로 벌어졌다가, 확관너트(30)가 확관부(10a)내로 완전히 투입되면, 걸림편(104) 하단의 걸림턱(104a)이 확관너트(30)의 하단부에 걸리면서 설치관(10)과 확관너트(30)의 결합이 이루어지므로서 결합과정을 보다 신속하고 편리하게 수행할 수 있게 되는 것이다.On the other hand, the engaging piece 104 formed on the lower end of the expansion pipe portion 10a of the installation pipe 10 is made of a thin long rod shape, even if integrated with the same material as the installation pipe 10 to some degree of elasticity In order to exert the conical expansion nut 30 into the expansion pipe portion 10a of the installation pipe 10, the locking piece 104 is opened outward, and the expansion nut 30 is expanded. When fully inserted into (10a), while the engaging jaw (104a) of the lower end of the engaging piece 104 is caught in the lower end of the expansion nut 30, the coupling pipe 10 and the expansion nut 30 is made to combine the coupling process It will be faster and easier to perform.
아울러, 확관너트(30)의 외주면에는 설치관(10)에 형성된 걸림편(104)이 끼워지는 걸림홈부(302)가 형성되어 있어서, 설치관(10)과 확관너트(30)를 결합하게되면, 설치관(10)의 걸림편(104)이 확관너트(30)의 걸림홈부(302)내에 투입되므로서 설치관(10)에 결합된 확관너트(30)가 회전하는 것을 방지하기 때문에, 첨부도면 도 4와 같이 앙카볼트를 설치할 때, 확관너트(30)와 체결되는 볼트(20)를 회전시키는 과정에서 설치관(10)과 확관너트(30)간의 미끄러짐으로 인한 확관너트(30)의 회전을 방지할 수 있게되어 앙카볼트의 설치가 보다 신속하고 간편하게 이루어질 수 있게 되는 것이다.In addition, the outer circumferential surface of the expansion nut 30 is formed with a locking groove 302 into which the locking piece 104 formed in the installation tube 10 is fitted, so that when the installation tube 10 and the expansion nut 30 are combined, Since the locking piece 104 of the installation pipe 10 is inserted into the locking groove 302 of the expansion nut 30 to prevent the expansion nut 30 coupled to the installation pipe 10 from rotating, When the anchor bolt is installed as shown in FIG. 4, the expansion nut 30 is rotated due to slippage between the installation pipe 10 and the expansion nut 30 in the process of rotating the bolt 20 fastened to the expansion nut 30. Being able to prevent the installation of the anchor bolt will be made more quickly and simply.
한편, 본 고안의 도면에서 설치관(10)의 하단부에 형성되는 걸림편(104)의 숫자는 3개로 도시되어있으나 이에 한정하는 것은 아니며, 적절한 탄력성을 가지고 설치관(10)의 확관부(10a)에 결합된 확관너트(30)가 임의로 분리되지 않을 정도의 결합력을 유지할 수 있는 범위 내에서 걸림편(104)의 숫자는 변경될 수 있음을 미리 밝혀두는 바이다.On the other hand, the number of the engaging piece 104 is formed in the lower end of the installation pipe 10 in the drawings of the present invention is shown as three, but is not limited to this, the expansion portion 10a of the installation pipe 10 with an appropriate elasticity Note that the number of the engaging pieces 104 can be changed in advance within the range in which the expansion nut 30 coupled to the coupling nut 30 can maintain the coupling force such that the expansion nut 30 is not separated.
상술한 바와 같이 본 고안은 앙카볼트를 구성하는 설치관과 확관너트의 결합을 보다 신속하고 간편하게 수행할 수 있으므로 앙카볼트의 생산과정에서 셋트의 구성이 용이하여 생산능률을 향상시킬 수 있을 뿐 만 아니라, 간단하면서도 견고한 결합을 통해 설치관과 확관너트의 미끄러짐을 방지하므로서 앙카볼트의 시공성을 크게 향상시킬 수 있는 이점이 있다.As described above, the present invention can perform the combination of the installation pipe and the expansion nut constituting the anchor bolt more quickly and simply, so that the configuration of the set is easy in the production process of the anchor bolt, thereby improving the production efficiency as well. In addition, it is possible to greatly improve the constructability of the anchor bolt by preventing slippage of the installation pipe and expansion nut through a simple and solid coupling.
