볼트몸체(130)는 일측면이 중심부를 향해 개구되어 'C'형상을 갖는 두꺼운 원반 모양으로, 외주면에 나사산(131)이 형성된다.Bolt body 130 is a thick disk shape having one side is opened toward the center of the 'C' shape, the thread 131 is formed on the outer peripheral surface.

도 4에 도시된 바와 같이, 볼트몸체(130)는 외주면의 일부에 형성된 개구(132)가 중심부의 삽입홀(133)과 연결 형성된다.As shown in FIG. 4, in the bolt body 130, an opening 132 formed in a portion of the outer circumferential surface is connected to the insertion hole 133 of the center portion.

한편, 볼트몸체(130)의 다른 일측 외주면에는 상기 삽입홀(133)까지 관통되는 나사홀(134)이 형성되고, 이 나사홀(134)에는 무두(headless)볼트(150)가 삽입 결합된다.On the other hand, the other one outer peripheral surface of the bolt body 130 is formed with a screw hole 134 that penetrates to the insertion hole 133, the headless bolt 150 is inserted and coupled to the screw hole 134.

무두볼트(150)는 후술하는 바와 같이 삽입홀(133)에 삽입되는 콘크리트 구조물(도 5의 2 참조)측 철골(도 5의 13 참조)을 볼트몸체(130)에 밀착 고정시키기 위한 고정수단으로서 기능한다.The tannery bolt 150 is a fixing means for tightly fixing the steel frame (see 13 in FIG. 5) side of the concrete structure (see 2 in FIG. 5) inserted into the insertion hole 133 to the bolt body 130. Function.

이를 위해 무두볼트(150)의 내측 일단부는 삽입홀(133)에 삽입되는 상기 철골을 가압하여 고정시키고, 외측의 타단부에는 회전 구동을 위해 6각의 렌치홈부(151)가 형성된다.To this end, the inner end of the tannery bolt 150 is fixed by pressing the steel frame inserted into the insertion hole 133, the other end of the hexagonal wrench groove 151 is formed for rotational drive.

이 렌치홈부(151)에 육각렌치(도면 미도시)를 삽입하여 회전시킴으로써 무두볼트(150)의 전후진 회전 구동을 달성한다.By inserting and rotating a hexagon wrench (not shown) into the wrench groove 151, forward and backward rotation driving of the tannery bolt 150 is achieved.

한편, 도 3에서, 너트몸체(140)는 볼트몸체(130)와 마찬가지로 일측면이 중심부를 향해 개구되어 'C'형상을 갖는 두꺼운 원반 모양을 갖는다.On the other hand, in Figure 3, the nut body 140 has a thick disk shape having a 'C' shape, one side is opened toward the center like the bolt body 130.

너트몸체(140)의 내주면에는 나사산(141)이 형성되어 상기 볼트몸체(130)의 외주면(131)과 나사결합된다.A thread 141 is formed on the inner circumferential surface of the nut body 140 to be screwed to the outer circumferential surface 131 of the bolt body 130.

너트몸체(140)는 내주면의 일측에 형성된 개구(142)가 외주면을 통해 외부와 연결된다.Nut body 140 has an opening 142 formed on one side of the inner peripheral surface is connected to the outside through the outer peripheral surface.

또한, 너트몸체(140)의 외주면에는 원주방향으로 복수의 개소에 회전조작을 위한 키홈(143)이 형성된다.In addition, a key groove 143 is formed on the outer circumferential surface of the nut body 140 for rotational operation at a plurality of locations in the circumferential direction.

키홈(143)에 키 스패너(도면 미도시)를 삽입하여 회전시킴으로써 볼트몸체(130)에 나사결합된 너트몸체(140)의 회전조작력을 높일 수 있다.By inserting and rotating a key spanner (not shown) in the key groove 143, it is possible to increase the rotational operation force of the nut body 140 screwed to the bolt body 130.

이상과 같이 구성되는 본 발명의 실시예에 따른 콘크리트 구조물용 난간대 어셈블리(10))의 설치과정을 설명하면, 먼저 도 5에 도시된 바와 같이, 일체로 형성된 난간 받침대(110)와 난간줄 걸이봉(120)을 콘크리트 구조물(2)의 상면에 세운 후 상기 콘크리트 구조물(2)로부터 돌출 형성되는 철골(13)이 상기 난간 받침대(110)의 유입로(111)를 지나 그 끝단의 걸림로(112)에 삽입되어 이를 통해 상부로 돌출되도록 한다.Referring to the installation process of the handrail assembly 10 for a concrete structure according to an embodiment of the present invention configured as described above, first, as shown in FIG. After placing 120 on the upper surface of the concrete structure 2, the steel frame 13 protruding from the concrete structure 2 passes through the inflow path 111 of the railing pedestal 110 and the end of the locking path 112. ) To protrude upward through it.

그리고, 도 6에 도시된 바와 같이, 난간 받침대(110) 상면에 볼트몸체(130)를 탑재하고 상기 걸림로(112)를 통해 돌출된 철골(13)이 볼트몸체(130)의 개구(132)를 지나 중심부의 삽입홀(133)에 삽입되도록 한다.And, as shown in Figure 6, mounting the bolt body 130 on the top surface of the railing pedestal 110 and the steel frame 13 protruding through the locking path 112 is the opening 132 of the bolt body 130 Pass through the insertion hole 133 of the center.

그리고 나서, 볼트몸체(130)의 일측면에 형성된 홀(134)에 육각렌치를 삽입 결합시켜 내부의 무두볼트(도 4의 150)를 회전구동시켜 상기 삽입홀(133)에 삽입된 철골(13)을 가압하여 상기 삽입홀(133) 면에 접촉 고정시킨다.Then, the hexagonal wrench is inserted into the hole 134 formed on one side of the bolt body 130 to drive the inner tannery bolt (150 of FIG. 4) to rotate the steel frame 13 inserted into the insertion hole 133. ) To press and fix the contact surface to the insertion hole 133.

이후, 도 7에 도시된 바와 같이, 볼트몸체(130)의 외주면에 너트몸체(140)를 나사결합시켜 회전시키면서 상기 너트몸체(140)의 바닥면이 난간 받침대(110)의 상면에 밀착 결합되도록 한다.Subsequently, as shown in FIG. 7, the bottom surface of the nut body 140 is tightly coupled to the top surface of the railing pedestal 110 while screwing and rotating the nut body 140 to the outer circumferential surface of the bolt body 130. do.

최종적으로는, 상기 너트몸체(140) 외주면의 키홈(143)에 결합되는 키 스패너(도면 미도시)를 이용하여 난간 받침대(110)에 대한 밀착력이 더욱 커지도록 한다.Finally, by using a key spanner (not shown) coupled to the key groove 143 on the outer circumferential surface of the nut body 140, the adhesion to the railing pedestal 110 is increased.

결과적으로, 콘크리트 구조물(2)에 고정된 철골(13)에는 무두볼트(도 4의 150)를 통해 볼트몸체(130)가 일체로서 결합되고, 이 볼트몸체(130)를 통해서는 너트몸체(140)가 나사결합하여 난간 받침대(110)의 상면을 가압, 콘크리트 구조물(2)의 상면에 밀착 고정시키게 된다.As a result, the bolt body (130) is integrally coupled to the steel frame (13) fixed to the concrete structure (2) through the tanned bolt (150 in Figure 4), through the nut body (140) through the bolt body (130) ) Is screwed to press the upper surface of the railing pedestal 110 to be fixed in close contact with the upper surface of the concrete structure (2).

이에 따라, 난간 받침대(110) 및 이와 일체로 결합되어 기립된 난간줄 걸이봉(120)은 단일의 철골(130)을 매개로 콘크리트 구조물(2) 상에 고정될 수 있다.Accordingly, the railing pedestal 110 and the railing bar hanger rod 120 that is integrally coupled to the railing pedestal 110 may be fixed on the concrete structure 2 via a single steel frame 130.

한편, 이상에서 설명된 콘크리트 구조물용 난간대 어셈블리(100)는 본 발명의 이해를 돕기 위한 일 실시예에 불과하므로 본 발명의 권리범위 내지 기술적 범위가 상기 설명된 바에 한정되는 것으로 이해되어서는 곤란하다.On the other hand, the handrail assembly 100 for concrete structures described above is only one embodiment for helping the understanding of the present invention, it is difficult to understand that the scope of the present invention to the technical scope is limited to those described above.

본 발명의 권리범위 내지 기술적 범위는 후술하는 특허청구범위 및 그 균등범위에 의해 정하여진다.The scope of the present invention is defined by the appended claims and their equivalents.
