도 2는 본 발명에 따른 록볼트용 고정장치의 분해사시도이고, 도 3의 (a)와 (b)는 본 발명에 따른 록볼트용 고정장치의 사용상태를 보인 요부 단면도이며, 도 4는 본 발명에 따른 록볼트용 고정장치의 다른 설치상태를 보인 요부 단면도이고, 도 5는 본 발명에 따른 록볼트용 고정장치가 설치된 단면도이다.Figure 2 is an exploded perspective view of the fixing device for rock bolts according to the present invention, Figure 3 (a) and (b) is a sectional view showing the main portion showing the state of use of the fixing device for rock bolts according to the invention, Figure 4 Fig. 5 is a cross-sectional view showing main parts showing another installation state of the fixing device for the rock bolt according to the present invention, and FIG.

먼저, 고정장치(1)는 크게 나누어 천공구멍(40) 속으로 삽입 고정되는 록볼 트부재(30)의 선단에 결합되어지는 고정부재(10)(10')와, 상기 고정부재(10)(10')의 외주연에 체결되어 천공구멍(40)으로부터 록볼트부재(30)의 이탈을 방지하는 걸림수단(20)으로 구분된다.First, the fixing device 1 is largely divided into fixing members 10 and 10 ′ coupled to the front end of the rock bolt member 30 to be inserted into and fixed into the drilling hole 40, and the fixing member 10 ( 10 ') is divided into a locking means 20 which is fastened to the outer circumference of the 10 &quot; to prevent the lock bolt member 30 from being separated from the boring hole 40.

상기 고정부재(10)(10')는 수지재질의 반원통형상으로서 2개 1조로 형성되어 이들의 결합시 하나의 원통형상을 구성하게 되는데, 상기 고정부재(10)(10')의 내주연에 이형철근이나 나사봉 등으로 된 록볼트부재(30)의 돌기부(31)가 걸려 결합되는 체결턱(11)(11')이 다수 형성된다. The fixing members 10 and 10 'are formed of two semi-cylindrical shapes of a resin material to form one cylindrical shape when they are combined, and the inner circumference of the fixing members 10 and 10' is fixed. A plurality of fastening jaws (11, 11 ') is formed in which the projections 31 of the lock bolt member 30 made of a deformed reinforcing bar or a screw rod is engaged.

이때, 이형철근으로 된 록볼트부재(30)의 돌기부(31)가 도 3의 (a)와 같이 링형상으로 일정할 경우에는 두 고정부재(10)(10')의 체결턱(11)(11')을 상호 대향되게 형성하는 반면, 도 3의 (b)와 같이 록볼트부재(30)의 돌기부(31)가 엇갈려 형성된다.At this time, when the protrusion part 31 of the rock bolt member 30 made of a deformed steel bar is constant in a ring shape as shown in FIG. 3 (a), the fastening jaws 11 of the two fixing members 10, 10 '( 11 ') are formed to face each other, and the protrusions 31 of the lock bolt member 30 are alternately formed as shown in FIG.

그리고, 상기 고정부재(10)(10')의 외주연에는 양단부의 직경보다 다소 작은 소정 직경의 착설홈(12)(12')이 마련된다.And, on the outer periphery of the fixing member (10, 10 ') is provided a mounting groove 12, 12' of a predetermined diameter slightly smaller than the diameter of both ends.

또한, 두 고정부재(10)(10')가 상호 면접되는 양측에는 소정 높이의 끼움돌기(13)(13')와, 상기 끼움돌기(13)(13')가 삽입되는 고정공(14)(14')이 서로 반대되는 위치에 함께 마련되어 두 고정부재(10)(10')가 결합되었을 때 다른 고정부재(10)의 끼움돌기(13)는 또 다른 고정부재(10')의 고정공(14')에 결합되고, 또 다른 고정부재(10')의 끼움돌기(13')는 다른 고정부재(10)의 고정공(14)과 결합된다. 이때, 도 2와 같이 두 고정부재(10)(10') 중 하나의 고정부재(10')를 돌리더라도 끼움돌기(13)(13')와 고정공(14)(14')이 서로 결합되도록 함이 중요하다.In addition, the fitting protrusions 13 and 13 'having a predetermined height and the fixing holes 14 into which the fitting protrusions 13 and 13' are inserted at both sides where the two fixing members 10 and 10 'are mutually interviewed. 14 'are provided together at opposite positions, and when the two fixing members 10 and 10' are combined, the fitting protrusion 13 of the other fixing member 10 is fixed to another fixing member 10 '. 14 ', the fitting protrusion 13' of the other fixing member 10 'is coupled to the fixing hole 14 of the other fixing member 10. At this time, the fitting protrusions 13 and 13 'and the fixing holes 14 and 14' are coupled to each other even if one of the two fixing members 10 and 10 'is rotated. It is important to make sure.

그리고, 한쌍의 고정부재(10)(10') 중 어느 하나의 고정부재(10)의 단부에 선단으로 갈수록 첨예해지는 원추형상의 뾰족부(15)를 형성하여 천공구멍(40)으로의 삽입을 매우 용이하게 한다.Then, at the end of any one of the pair of fastening members 10, 10 ', a conical pointed portion 15 is sharpened toward the tip to be inserted into the drilling hole 40. To facilitate.

상기 끼움돌기(13)(13')와 고정공(14)(14')이 구비된 두 고정부재(10)(10')의 양측에 이형철근과 같은 록볼트부재(30)의 리브(32)가 안착되는 안착홈(16)(16')을 각각 형성한다. Ribs 32 of the rock bolt member 30, such as a deformed rebar, on both sides of the two fixing members 10, 10 'provided with the fitting protrusions 13, 13' and fixing holes 14, 14 '. ) Respectively form the seating grooves 16 and 16 '.

상기 걸림수단(20)은 금속판(22)을 원통형상으로 말아 그 내주연이 고정부재(10)(10')의 착설홈(12)(12')에 면접 밀착되게 하는 것으로서, 상기 걸림수단(20)의 여러 개소에 일부를 절단한 다음, 그 외측방으로 절곡시킴으로써 천공구멍(40)과 대응되는 걸림돌기(21)가 형성된다. 이때, 상기 걸림수단(20)의 걸림돌기(21)가 비스듬히 기울어진 상태를 유지하게 되므로 천공구멍(40)으로의 삽입시에는 다소 탄압된 상태로 그 진입이 매우 용이한 반면, 천공구멍(40)으로부터 록볼트부재(30)를 후퇴시킬 시에는 상기 천공구멍(40)의 내벽에 걸림수단(20)의 걸림돌기(21)가 걸려 빠지지 않게 된다.The locking means 20 is to roll the metal plate 22 in a cylindrical shape so that its inner circumference is in close contact with the mounting grooves 12 and 12 'of the fixing members 10 and 10'. A part of the part 20 is cut and then bent outwardly to form a locking projection 21 corresponding to the drilling hole 40. At this time, the locking projection 21 of the locking means 20 is maintained at an inclined state so that when the insertion into the drilling hole 40 is slightly suppressed, its entry is very easy, while the drilling hole 40 At the time of retreating the lock bolt member 30, the locking projection 21 of the locking means 20 is not caught by the inner wall of the drilling hole 40.

그리고, 상기 상기 걸림수단(20)의 걸림돌기(21)는 금속판(22)이 원통으로 절곡되었을 때 방사상으로 균일하게 돌출됨으로써, 상기 걸림수단(20)이 천공구멍(40) 내부의 정중앙에 위치하게 된다.In addition, the locking protrusion 21 of the locking means 20 is radially uniformly protruded when the metal plate 22 is bent in a cylinder, so that the locking means 20 is located at the center of the inside of the drilling hole 40. Done.

한편, 상기 고정부재(10)(10')의 착설홈(12)(12') 양측에 걸림수단(20)의 금속판(22) 양측단부를 끼워 이의 벌어짐을 방지할 수 있게 끼움홈(17)(17')을 형성함이 바람직하다.On the other hand, the fitting groove (17) to insert the both ends of the metal plate 22 of the locking means 20 on both sides of the mounting grooves 12, 12 'of the fixing member (10) (10'). It is preferable to form (17 ').

상기와 같이 구성된 록볼트용 고정장치(1)의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the action and effect of the lock bolt fixing device 1 configured as described above in detail as follows.

먼저, 도 2에 도시된 바와 같이 하나의 고정부재(10) 내주연에 록볼트부재(30)의 단부를 결합시키는데, 이때 상기 록볼트부재(30)의 돌기부(31)가 고정부재(10)의 체결턱(11)에 걸리도록 결합한다. First, as shown in FIG. 2, the end of the lock bolt member 30 is coupled to the inner circumference of one fixing member 10, wherein the protrusion 31 of the lock bolt member 30 is fixed to the fixing member 10. It is coupled to be caught in the fastening jaw (11).

그런 다음, 상기 록볼트부재(30)가 설치되어진 고정부재(10)에 또 하나의 고정부재(10')를 상호 결합시키게 되는데, 이때 도 3의 (a)와 같이 록볼트부재(30)의 돌기부(31)가 링형상으로 일정할 경우에는 두 고정부재(10)(10')의 체결턱(11)(11')이 상호 대향되게 고정부재(10')를 결합한다.Then, another fixing member 10 'is coupled to the fixing member 10 on which the lock bolt member 30 is installed. In this case, the lock bolt member 30 of FIG. When the protrusions 31 are fixed in a ring shape, the fixing jaws 11 and 11 'of the two fixing members 10 and 10' are coupled to each other so that the fixing members 10 'are opposed to each other.
