본 발명은 쏘일네일의 두부보호 조임장치에 관한 것으로, 특히 그라우트체에 고정형성되어 외부로 돌출 형성된 쏘일네일에 대하여 외부환경으로 인한 부식과 침식을 방지하는 쏘일네일의 두부보호 조임장치에 관한 것이다.The present invention relates to a head protection tightening device of a soil nail, and more particularly to a head protection tightening device of a soil nail to prevent corrosion and erosion caused by the external environment with respect to the soil nail fixedly formed on the grout body.

일반적으로, 산악지형 등에 개설된 도로변에는 암벽, 암반, 토사 등을 포함한 경사지면이 많고, 이들 도로는 경사지면 으로부터 발생되는 사면 붕괴에 대하여 노출된다.In general, there are many sloped roads including rock walls, rocks, earth and sand, etc. on roadsides opened in mountainous terrain, and these roads are exposed to slope collapse generated from sloped roads.

이러한 사면 붕괴는 지진 또는 도로를 통해하는 차량 등에 의한 각종 충격 및 해빙기를 비롯한 풍우작용과 중력작용 등으로 그 지지기반이 약해짐에 따라 붕괴되는 현상이다.This slope collapse is a phenomenon that collapses as the support base weakens due to wind and gravitational action, such as various shocks and thawing by vehicles such as earthquakes or roads.

따라서, 이러한 사면 붕괴의 위험을 최소화하기 위해 사면을 일정각도로 경사지게 형성하고, 아울러 이 사면으로부터 도로로 낙석 및 토사가 흘러내리는 것을 방지하기 위해 다양한 형태의 사면안정공사가 실시되고 있는 실정이다.Therefore, in order to minimize the risk of the collapse of the slope to form a slope at an angle, and also to prevent the falling of the rock and soil from the slope from the slope of the various types of slope stabilization work is being carried out.

이러한 사면붕괴 현상을 방지하기 위한 사면안정공사는, 암반 등의 사면에서 붕괴 위험이 있는 부위 즉, 경사지면 상에 일정간격으로 3∼5m 정도의 깊이 또는 그 이상의 깊이로 삽입공을 다수 형성하고, 이 삽입공에 일정길이를 갖는 쏘일네일를 삽입하여 몰탈 등을 충진시켜 고정하는 것이다.Slope stabilization work to prevent such slope collapse phenomenon is to form a large number of insertion holes at a depth of about 3 to 5m or more at a predetermined interval on the slope, such as a rock, such as the risk of collapse on the slope, The nail is inserted into the insertion hole and filled with mortar or the like to fix it.

이와 같이 고정된 쏘일네일의 단부는 경사지면의 표면으로부터 돌출된 형상을 이루게 되고, 이 돌출된 쏘일네일의 단부에는 일정한 두께와 강성을 갖는 방사형의 지지판이 관통되어 위치되며, 이후 쏘일네일와 짝을 이루는 너트가 체결됨에 따라 상기한 지지판은 경사지면의 표면에 대향하여 밀착됨과 동시에 쏘일네일와 너트의 체결력에 대응하여 경사지면의 표면을 지지하게 된다.The ends of the fixed nails thus form a shape protruding from the surface of the inclined surface, the radial support plate having a constant thickness and stiffness is positioned through the end of the protruding soil nails, and then paired with the nails As the nut is fastened, the support plate is in close contact with the surface of the inclined surface and simultaneously supports the surface of the inclined surface in response to the fastening force of the nail and the nut.

이와 같은 종래 쏘일네일 연계 보강장치의 전형적인 일례가 도 1에 도시되어 있다.A typical example of such a conventional nail nail associated reinforcement is shown in FIG.

도 1에서 부재번호 1은, 경사지면 2는 삽입공, 3은 쏘일네일, 4는 그라우트, 5는 철근, 6은 지지판, 7은 너트를 각각 가리킨다.In Fig. 1, reference numeral 1 denotes an inclined surface 2, an insertion hole, 3 denotes a nail, 4 grout, 5 reinforcement, 6 a support plate, and 7 a nut.

상기와 같은 암반 등의 경사지면(1)에 삽입공(2)을 천공하고, 이 삽입공(2)에 쏘일네일(3)를 일정깊이로 삽입하여 몰탈 등으로 그라우팅(4)을 실시하여서 경사지면(1)에 대하여 쏘일네일(3)를 고정시키되, 이러한 각 쏘일네일(3)들을 연계고정하기 위하여 종방향 또는 횡방향으로 철근(5) 및 와이어 등을 연결하여 지지판(6)으로 밀착시킨 후, 너트(7)로서 조여 마찰력에 의해 각 쏘일네일 고정부위가 연계 고정되도록 함으로써, 쏘일네일 고정부위와, 쏘일네일과 쏘일네일 사이가 붕괴되는 것을 예방하는 것이다.The insertion hole 2 is drilled in the inclined surface 1 such as the rock, and the nail nail 3 is inserted into the insertion hole 2 to a predetermined depth, and the grouting 4 is performed by mortar or the like. Fixing the nail (3) to the ground (1), in order to connect the fixed each of these nail nails (3) by connecting the reinforcing bars (5) and wires in the longitudinal or transverse direction and in close contact with the support plate (6) Then, by tightening the nut 7 so that the respective nail nail fixing portions are fixedly connected by the frictional force, it is to prevent the collapse between the nail nail fixing portion, the soil nail and the nail.

그러나 상기와 같은 종래의 쏘일네일 연계 보강장치의 락볼트(레일)은 너트로 고정된 일부분이 외부로 돌출하여 설치가 되어 외부로부터의 습기나 기타 침식작용 등에 노출되어 쉽게 부식되는 문제점이 있었으며, 또한 이러한 부식에 의한 결과로 유지보수시 너트가 조여지거나 풀리지 않은 문제점과, 철근을 이용하여 지 지판을 지지하는 구조를 택해 철근 또한 부식으로 인해 부식된 부분이 이탈되어 철근의 지름이 작아지거나 끊어져 지지판에 작용하는 지지력이 상실되거나 불균형적으로 작용되는 문제점이 있었다.However, the rock bolt (rail) of the conventional nail nail associated reinforcement device is a part fixed by the nut is installed to protrude to the outside has a problem of being easily corroded by exposure to moisture or other erosion from the outside, and As a result of this corrosion, the nut is not tightened or loosened during maintenance, and the structure that supports the fingerboard by using reinforcing bars is selected. There was a problem that the supporting force is lost or acting disproportionately.

이에 본 발명은 상기와 같은 종래 기술의 문제점을 감안하여 안출한 것으로 외내부에 나사선을 형성하고 2개 1조로 이루어진 라이너 스크류를 쏘일네일이나 이형철근에 체결하여 상기 라이너 스크류의 외부를 상부가 막힌 캡 너트를 결합시켜 캡 너트를 회전시키게 되면 그라우트에 매입되어 고정된 쏘일네일이나 이형철근에 인장력을 가하게 하여 지압판고 경사지면에 지지력을 향상시키며, 캡 너트로 인해 부식과 침식을 방지할 수 있는 쏘일네일의 두부보호 조임장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the problems of the prior art as described above to form a screw thread on the outside and to fasten the liner screw consisting of two pairs of nail nails or deformed rebar to the outside of the liner screw cap closed When the cap nut is rotated by coupling the nut, it is embedded in the grout to apply tension to the fixed nail or deformed reinforcing bar to improve bearing capacity on the slope of the chiropractor, and to prevent corrosion and erosion by the cap nut. The purpose of the present invention is to provide a head protection tightening device.

상기한 목적을 달성하기 위하여 본 발명은 암반 등의 경사지면(1)에 삽입공(2)을 천공하고, 이 삽입공(2)에 쏘일네일(3)를 일정깊이로 삽입하여 몰탈 등으로 그라우팅(4)을 실시하여 경사지면(1)에 대하여 쏘일네일(3)를 고정시키되, 이러한 각 쏘일네일(3)들을 연계고정하기 위하여 종방향 또는 횡방향으로 철근(5) 및 와이어 등을 연결하여 지지판(6)으로 밀착시킨 후, 너트(7)로서 조여 마찰력에 의해 각 쏘일네일 고정부위가 연계 고정되도록 함으로써, 쏘일네일 고정부위와, 쏘일네일과 쏘일네일 사이가 붕괴되는 것을 예방하도록 하는 쏘일네일 연계 고정장치에 있어서,In order to achieve the above object, the present invention perforates the insertion hole (2) in the inclined surface (1), such as rock, and inserting the nail nail (3) to a predetermined depth in the insertion hole (2) grouting with mortar, etc. (4) to fix the nail (3) with respect to the inclined surface (1), to connect the reinforcing bars (5) and wires, etc. in the longitudinal or transverse direction in order to link each of the nail (3) After the tight contact with the support plate 6, by tightening with a nut (7) so that each of the fixed nail fixed portion is fixed by friction force, so that the nail nail to prevent the collapse between the nail and the fixed nail portion and the nail In the interlocking fixture,
