도시한 바와 같이 본 발명은 상부 바디(10)와 하부 바디(20)와 행거 연결구(40)의 결합으로 이루어지는 구성이다.As shown in the present invention, the upper body 10 and the lower body 20 and the hanger connector 40 is composed of a combination.

본 발명의 구성에서 상부 바디(10)와 하부 바디(20)는 상부와 하부에서 서로 대칭되는 형상으로 구비되는 구성이다.In the configuration of the present invention, the upper body 10 and the lower body 20 are configured to be symmetrical with each other in the upper and lower.

즉 상부 바디(10)와 하부 바디(20)는 외주연 단부가 서로 마주보는 방향으로 절곡되도록 하고, 상부 바디(10)의 상부면과 하부 바디(20)의 하부면은 길이의 중간 부위에서 동일 수직선상에 각각 볼트홀(11)(21)이 형성되도록 한다.That is, the upper body 10 and the lower body 20 is to be bent in the direction in which the outer periphery end facing each other, the upper surface of the upper body 10 and the lower surface of the lower body 20 is the same at the middle of the length The bolt holes 11 and 21 are formed on the vertical lines, respectively.

특히 하부 바디(20)의 볼트홀(21)에는 암나사가 형성되도록 한다.In particular, the female screw is formed in the bolt hole 21 of the lower body 20.

이러한 상부 바디(10)와 하부 바디(20)의 볼트홀(11)(21) 전방측의 서로 마주보는 외주연 단부에는 상호 대응되도록 상부 톱니(12)와 하부 톱니(22)가 형성된다.The upper teeth 12 and the lower teeth 22 are formed so as to correspond to each other at the outer circumferential ends of the bolt holes 11 and 21 of the upper body 10 and the lower body 20 facing each other.

다만 상부 바디(10)와 하부 바디(20) 중 하부 바디(20)는 상부 바디(10) 보다는 후방으로 연장되게 형성되도록 하고, 상부 바디(10)의 후단부측 하향 절곡 단부는 하부 바디(20)의 하부면 후단부측에 형성한 가이드홀(23)을 수직 관통하여 승강 가능하도록 일정 높이가 하향 연장되도록 하여 가이드(13)를 형성하도록 한다.However, the lower body 20 of the upper body 10 and the lower body 20 is formed to extend to the rear than the upper body 10, the rear end side of the lower bent end of the upper body 10 is the lower body 20 The guide 13 is formed by extending a predetermined height downward to vertically penetrate the guide hole 23 formed at the rear end of the lower surface of the bottom surface.

한편, 본 발명의 구성에서 상부 바디(20)의 상부면에는 볼트홀(11) 상단부측 주연부를 따라 일방향으로 경사지게 돌기들이 돌출 형성되도록 하여 회전 방지용 요철(14)이 형성되게 하는 것이 보다 바람직하다.On the other hand, in the configuration of the present invention, it is more preferable that the projections protrude from one side to be inclined in one direction along the periphery of the upper end of the bolt hole 11 so that the protrusions and protrusions 14 are formed to prevent rotation.

또한, 상부 바디(10)의 가이드(13)에는 상부측 판면을 일정 직경으로 수평 관통되도록 하여 또 다른 행거가 연결될 수 있도록 채널 고정홀(15)이 형성되도록 한다.In addition, the guide 13 of the upper body 10 allows the upper side plate to be horizontally penetrated to a predetermined diameter so that the channel fixing hole 15 is formed so that another hanger can be connected.

이와 같은 상부 바디(10)와 하부 바디(20)는 각 볼트홀(11)(21)을 통해 조정 볼트(30)의 결합에 의해 연결된다.The upper body 10 and the lower body 20 are connected by the coupling of the adjustment bolt 30 through the respective bolt holes (11, 21).

이때의 조정 볼트(30)는 상부 바디(10)의 상부로부터 볼트홀(11)을 관통하여하부 바디(20)의 볼트홀(21)에 나사 결합되면서 동시에 관통하도록 한다.At this time, the adjustment bolt 30 passes through the bolt hole 11 from the upper portion of the upper body 10 to be screwed into the bolt hole 21 of the lower body 20 to pass through at the same time.

조정 볼트(30)에 의해서는 상부 바디(10)와 하부 바디(20)간의 간극이 조절되므로 조정 볼트(30)의 조작에 의해 빔과의 결합력이 조정된다.Since the gap between the upper body 10 and the lower body 20 is adjusted by the adjusting bolt 30, the coupling force with the beam is adjusted by the manipulation of the adjusting bolt 30.

다만 하부 바디(20)의 하부로 하향 돌출되는 조정 볼트(30)에는 행거가 직접 연결될 수도 있으며, 상부 바디(10)에서 볼트홀(11)의 상부에서는 조정 볼트(30)의 머리부가 걸려지도록 한다.However, a hanger may be directly connected to the adjustment bolt 30 protruding downwardly from the lower body 20, and the head of the adjustment bolt 30 is caught in the upper portion of the bolt hole 11 in the upper body 10. .

한편, 조정 볼트(30)의 머리부는 저면으로 볼트홀(11) 상단의 주연부에 형성되도록 한 회전 방지용 요철(14)과 대응하도록 하는 요철이 형성되게 하는 것도 보다 바람직하다.On the other hand, the head portion of the adjustment bolt 30 is more preferably such that the concave-convex to correspond to the anti-rotation concave-convex 14 to be formed in the peripheral portion of the upper end of the bolt hole 11 to the bottom.

상기와 같은 구성에서 하부 바디(20)에는 하부면의 전방으로 행거 연결구(40)가 구비되도록 한다.In the above configuration, the lower body 20 is provided with a hanger connector 40 in front of the lower surface.

행거 연결구(40)는 다시 행거축(41)과 밴드형 행거(42)로서 이루어지는 구성으로서, 행거축(41)은 상단부가 하부 바디(20)의 하부면 전방에서 열쇠구멍 형상으로 형성한 축홀(24)보다는 외경이 크게 형성되도록 하여 하향 이탈이 방지되도록 하고, 하부는 축홀(24)을 관통하여 일정 높이로 하향 연장되도록 하며, 하부의 연장 부위에는 수평의 관통홀(310)이 형성되도록 한다.The hanger connector 40 is configured as a hanger shaft 41 and a band-shaped hanger 42, and the hanger shaft 41 has a shaft hole having an upper end formed in a keyhole shape in front of the lower surface of the lower body 20 ( The outer diameter is formed to be larger than the 24 to prevent the downward departure, the lower portion penetrates the shaft hole 24 and extends downward to a predetermined height, and the horizontal through hole 310 is formed in the extension portion of the lower portion.

이러한 행거축(41)에는 밴드형 행거(42)의 상단부가 볼트 체결되도록 한다.The upper end of the band-shaped hanger 42 is bolted to this hanger shaft 41.

밴드형 행거(42)는 일정 폭으로 이루어지는 밴드를 삼각형 형상으로 형성되도록 한 형상이며, 분리되도록 한 상단부는 볼트(43)에 의해서 행거축(41)에 회전 가능하게 축결합된다.The band-shaped hanger 42 is a shape in which a band having a predetermined width is formed in a triangular shape, and the upper end portion separated from the band-shaped hanger is rotatably coupled to the hanger shaft 41 by a bolt 43.

즉 밴드형 행거(42)의 분리된 양측 상단부 사이로 행거축(41)의 하단부가 삽입되도록 하여 이들 상단부와 행거축(41)의 하단부를 볼트(43)가 수평 관통되도록 하여 너트 체결에 의해 행거축(41) 상단부를 축으로 수직 방향으로 회전 가능하게 연결된다.That is, the lower end portions of the hanger shafts 41 are inserted between the separated upper end portions of the band-shaped hangers 42, and the upper end portions and the lower end portions of the hanger shafts 41 are horizontally passed through the bolts 43, and the hanger shafts are fastened by the nut. (41) The upper end is rotatably connected in the vertical direction about the axis.

다만, 밴드형 행거(42)를 볼트(43)에 체결되도록 하기 위하여 밴드형 행거(42)의 상단부 일측에는 나선을 형성한 너트가 일체로 형성되도록 하거나 별도로 너트(44)가 체결되도록 한다.However, in order to fasten the band-shaped hanger 42 to the bolt 43, a nut formed with a spiral is integrally formed at one side of the upper end of the band-type hanger 42 or the nut 44 is separately fastened.

상기한 구성에 따른 빔 클램프에 의한 작용에 대해 보다 상세하게 설명하면 다음과 같다.Referring to the action by the beam clamp according to the above configuration in more detail as follows.

도 4는 본 발명에 따른 빔 클램프를 설치한 구조를 도시한 단면도로서, 도시한 바와 같이 본 발명은 빔(50)의 플랜지부에 연결되는 구성이다.Figure 4 is a cross-sectional view showing a structure in which the beam clamp according to the present invention is installed, as shown in the present invention is connected to the flange portion of the beam 50.

본 발명에서 상부 바디(10)와 하부 바디(20)는 조정 볼트(30)를 이용하여 간극이 조절되도록 한다.In the present invention, the upper body 10 and the lower body 20 to adjust the gap by using the adjustment bolt 30.

상부 바디(10)와 하부 바디(20)는 상부 바디(10)의 후방측 가이드(13)가 하부 바디(20)의 가이드홀(23)을 관통하도록 하면서 조정 볼트(30)를 상부 바디(10)의 상부로부터 볼트홀(11)을 관통하도록 삽입한 후 하부 바디(20)의 볼트홀(21)에 나사결합되도록 하여 상호 연결되도록 한다.The upper body 10 and the lower body 20 allow the adjusting bolt 30 to pass through the upper body 10 while allowing the rear guide 13 of the upper body 10 to pass through the guide hole 23 of the lower body 20. Inserted to penetrate through the bolt hole 11 from the top of the) to be screwed into the bolt hole 21 of the lower body 20 to be connected to each other.

조정 볼트(30)는 하부 바디(20)의 볼트홀(21)에 나사 결합되면서 하부 바디(20)를 하향 관통하게 된다.The adjusting bolt 30 is screwed into the bolt hole 21 of the lower body 20 to penetrate downward through the lower body 20.

이때 상부 바디(10)와 하부 바디(20) 사이에는 빔(50)의 플랜지부가 삽입되도록 한다.At this time, the flange portion of the beam 50 is inserted between the upper body 10 and the lower body 20.

즉 빔(50)의 플랜지를 상부 바디(10)와 하부 바디(20)의 상부 톱니(12)와 하부 톱니(22) 사이로 삽입되도록 하면서 조정 볼트(30)에 근접 또는 접촉되도록 한다.That is, the flange of the beam 50 is inserted between the upper teeth 12 and the lower teeth 22 of the upper body 10 and the lower body 20 to be in close proximity or contact with the adjusting bolt 30.

이와 같이 빔(50)의 플랜지부가 상부 바디(10)와 하부 바디(20) 사이에 위치되도록 한 상태에서 조정 볼트(30)를 회전시켜 조정 볼트(30)와 나사 결합되어 있는 하부 바디(20)가 상승되도록 한다.As such, the lower body 20 which is screwed with the adjusting bolt 30 by rotating the adjusting bolt 30 in a state where the flange portion of the beam 50 is positioned between the upper body 10 and the lower body 20. Allow to rise.

하부 바디(20)가 비록 조정 볼트(30)와의 나사 결합에 의해 회전하기는 하나 상부 바디(10)는 후단부의 가이드(13)가 하부 바디(20)의 가이드홀(23)을 관통하도록 하고 있으므로 하부 바디(20)는 회전하지 않고 단지 조정 볼트(30)의 주면을 따라서 상승하게 된다.Although the lower body 20 rotates by screwing with the adjusting bolt 30, the upper body 10 allows the guide 13 of the rear end to penetrate the guide hole 23 of the lower body 20. The lower body 20 does not rotate but only rises along the major surface of the adjustment bolt 30.

하부 바디(20)가 상승되도록 하여 상부 바디(10)의 상부 톱니(12)와 하부 바디(20)의 하부 톱니(21)에 빔(50)의 플랜지부 상부면과 하부면이 압착되도록 한다.The lower body 20 is raised so that the upper and lower surfaces of the flange portion of the beam 50 are compressed to the upper teeth 12 of the upper body 10 and the lower teeth 21 of the lower body 20.

빔(50)의 플랜지부에 상부 바디(10)의 상부 톱니(12)와 하부 바디(20)의 하부 톱니(22)가 강력하게 압착되도록 하면 본 발명은 설치가 완료된다.If the upper teeth 12 of the upper body 10 and the lower teeth 22 of the lower body 20 are strongly compressed to the flange portion of the beam 50, the present invention is completed installation.
