Description
본 고안은 석재를 벽면에 부착하기 위해 벽면에 천공하는 앙카구멍을 상협하광한 형태로 천공하여 앙카볼트를 보다 견고하게 고정할 수 있도록 함을 목적으로 고안한 석재 고정용 앙카구멍 천공장치에 관한 것이다.The present invention relates to a stone anchoring hole hole drilling device designed for fixing the anchor bolt more firmly by drilling the anchor hole drilled on the wall surface in the form of a flat bottom to attach the stone to the wall surface. .
일반적으로 건축물의 외벽에 많이 부착하는 석재는 벽면에 앙카구멍을 천공하여 이에 고정한 앙카볼트에 의해 부착하게 되는 데 종래 벽면에 천공하는 앙카구멍은 도 5 와 같이 회전축에 취부한 바이트 팁의 정회전으로 상하의 구멍 직경이 동일하게 천공하므로 매설하는 앙카볼트가 쉽게 빠지게 되는 경우가 허다하여 작업시외벽의 석재가 떨어지게 되므로서 안전상 매우 위험을 초래하게 되는 폐단이 있었다.Generally, the stone that is attached to the outer wall of the building is attached to the wall by anchor bolt fixed to it by drilling the anchor hole on the wall, but the anchor hole drilled on the conventional wall surface by the forward rotation of the bite tip attached to the rotating shaft as shown in FIG. Since the hole diameters of the upper and lower holes are the same, the anchor bolts are often easily removed and the stone on the outer wall falls during operation, resulting in a very dangerous danger.
본 고안은 이와같은 점을 감안하여 고안한 것으로 앙카구멍을 천공하는 회전축을 일정한 깊이에 이르면 요동되게 회전시켜 상협하광한 앙카구멍을 형성하므로서 종래의 폐단을 해소한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been devised in view of the above, and solves the conventional discontinuity by forming an anchor hole with upper and lower beams by rotating the rotating shaft drilling the anchor hole to a certain depth, which will be described in detail according to the accompanying drawings.

에어의 구동력으로 회전하는 회전축(1)의 내부에 급수공(2)을 관통시키고 이의 외주 중간부에 스프링(3)을 관삽한 안내봉(4)을 매개로 승강자재되는 지지용 브라켓트(5)와 커버(6)를 설치한 통상의 천공장치에 있어서, 회전축(1)의 상부에 일정길이의 소경부(7)를 단입 형성하고, 회전축(1)과 접면하는 지지브라켓트(5)에 설치된 부시(8)의 하부에 볼시트(9)의 외면에서 회전자재되는 플렉시블한 지지볼(10)을 관통 설치하여서 됨을 특징으로 하는 것이다.A support bracket (5) which is provided with a lifting material through a guide rod (4) penetrating the water supply hole (2) inside the rotating shaft (1) rotated by the driving force of the air, and the spring (3) is inserted into the outer peripheral middle thereof. In a conventional drilling device provided with a cover 6, a bush is provided on the support bracket 5 which is formed by inserting a small diameter portion 7 having a predetermined length into the upper portion of the rotating shaft 1 and contacting the rotating shaft 1. It is characterized in that the lower part of the (8) through the flexible support ball 10 which is rotated on the outer surface of the ball seat (9).
도면중 미설명 부호 11은 볼시트(9)를 지지브라켓트(5)에 고정하는 보울트이고, 12는 회전축(1)의 하단에 설치한 바이트 팁이며, 13은 급수호스이고, 14는 패킹이며, 15는 석재에 천공된 앙카구멍이다.In the figure, reference numeral 11 is a bolt for fixing the ball seat 9 to the support bracket 5, 12 is a bite tip installed at the lower end of the rotating shaft 1, 13 is a water supply hose, 14 is a packing, 15 is the anchor hole drilled in the stone.
이와같이 된 본 고안은 앙카구멍(15)을 천공할 벽면에 회전축(1)하단의 바이트 팁(12)을 당접시킨 상태에서 공압으로 회전축(1)을 회전시켜 구멍을 천공하게 되면 회전축(1)의 바이트 팁(12)이 벽면속으로 들어감과 동시에 그 외주에 관삽한 캡(6)과 지지브라켓트(5)가 안내봉(4)을 매개로 회전축(1)을 따라 위로 서서히 상승되면서 앙카구멍(15)을 천공하게 되는 데 이때 회전축(1)은 지지브라켓트(5)의 부시(8)와 긴밀하게 접면되어 정속회전을 하게 되므로 앙카구멍(15)은 바이트 팁 (12)의 직경으로 상하가 일정한 크기로 뚫어지게 된다.The present invention has been made in such a way to rotate the rotating shaft (1) by pneumatic pressure in the state in which the bite tip 12 of the lower end of the lower end of the rotating shaft (1) in contact with the wall surface to drill the anchor hole (15) of the rotating shaft (1) As the bite tip 12 enters into the wall, the cap 6 and the support bracket 5 inserted into the outer circumference thereof are gradually raised upward along the rotation shaft 1 through the guide rod 4, and then the anchor hole 15 At this time, the rotating shaft (1) is in close contact with the bush (8) of the support bracket (5) is a constant speed rotation, so the anchor hole (15) is a constant size up and down by the diameter of the bite tip (12) It will be drilled into.
그런데 이같은 상태로 앙카구멍(15)이 천공되면서 지지브라켓트(5)가 상승하다가 회전축(1)의 상부에 단입상태로 형성한 소경부(7)에 도 2 와 같이 부시(8)가 위치하게 되면 회전축(1)의 외경과 일치하도록 형성된 지지브라켓트(5)의 부시(8)가 소경부(7)의 단입된 간격 만큼 회전축(1)과 이격되므로 회전축(1)을 전술한 상태와 같이 정속 회전하지 않고 이격부에 의거 사방으로 요동하게 되는 데 이때 부시(8)의 하방에는 플렉시블한 지지볼(10)이 당접되어 있고 당해 지지볼(10)은 지지브라켓트(5)에 보울트(11)로 고정된 볼시트(9)의 외면에 회전가능하게 접면되어 있으므로 회전축(1)이 소경부(7)에 의해 요동될 때 지지볼(10)에 의해 플렉시블한 지지상태에서 요동하게 됨에 따라 회전축(1)이 필요이상 요동되는 것을 방지하여 입구와 내부의 직경을 약간의 차이있게 천공할 수 있게 되는 것이다.However, when the anchor hole 15 is drilled in such a state, the support bracket 5 rises and the bush 8 is located in the small diameter portion 7 formed in the single-inserted state on the upper portion of the rotating shaft 1 as shown in FIG. 2. Since the bush 8 of the support bracket 5 formed so as to match the outer diameter of the rotating shaft 1 is spaced apart from the rotating shaft 1 by the interposed interval of the small diameter portion 7, the rotating shaft 1 is rotated at constant speed as described above. In this case, the flexible support ball 10 is abutted under the bush 8 and the support ball 10 is fixed to the support bracket 5 with the bolt 11. Since the rotary shaft 1 is foldably folded on the outer surface of the ball seat 9, the rotary shaft 1 is oscillated in a flexible support state by the support ball 10 when the rotary shaft 1 is rocked by the small diameter portion 7. This prevents the oscillation more than necessary, so that the diameter of the inlet and the inside is slightly You will be able to drill.
상기의 작용을 요약하면 천공초기에는 지지브라켓트(5)와 회전축(1)이 긴밀히 접면되어 정속 회전을 하므로서 앙카구멍을 상하가 일정한 직경으로 천공하게 되고 일정길이의 천공 후 지지브라켓트(5)가 소경부(7)에 위치되는 상태에서 요동되어 앙카구멍(15)의 내부를 입구보다 더 큰 직경으로 천공하게 되므로 도 4와 같이 입구가 협소하고 내부는 넓은형상의 앙카구멍(15)을 뚫을 수 있게 되는 것이다.In summary, in the beginning of the drilling, the support bracket (5) and the rotating shaft (1) are in close contact with each other to make constant rotation, so that the anchor hole is drilled up and down in a constant diameter, and the support bracket (5) is small after drilling of a certain length. In the state where it is located in the neck portion 7 is oscillated to drill the inside of the anchor hole 15 to a larger diameter than the inlet, so the inlet is narrow and the inside is wide as shown in FIG. It will be able to drill the anchor hole 15 of the shape.
이와같이 본 고안은 앙카구멍(15)을 입구가 좁고 내부는 넓은형상으로 형성한 것이므로 앙카보울트의 매설시 임의로 빠지지 않게 됨에 따라 석재를 견고하게 부착할 수 있는 등 그 효과가 매우 크다.In this way, the present invention is narrow in the opening of the anchor hole 15, the inside is wide Since it is formed in the shape, the effect is very large, such that the stone can be firmly attached to the anchor bolt when it is buried.
