Description

사면보강공사용 네일앵커{Anchor-nail Device for Slope-reinforcement-construction}Nail Anchor for Slope Reinforcement {Anchor-nail Device for Slope-reinforcement-construction}

본 발명은 사면보강공사용 네일앵커에 관한 것으로, 더욱 상세하게는 네일앵커 이형철근의 가공을 더욱 편리하게 하고, 결합부위의 강도를 더욱 보완하여 네일앵커의 생산성과 강성을 더욱 향상시킨 사면보강공사용 네일앵커에 관한 것이다.The present invention relates to a nail anchor for slope reinforcement, and more particularly, to facilitate the processing of the nail anchor deformed reinforcing bar, and to further enhance the strength of the coupling portion to improve the productivity and rigidity of the nail anchor for nail reinforcement It is about anchors.

산업이 발전함에 따라 기반도로나 단지조성 등 산지와 같은 사면을 개발하는 것은 불가피한 실정으로, 현재 사면의 슬라이딩 현실은 시간과 장소에 관계없이 끊임없이 발생하고 있으며, 생명과 재산을 위협하는 주변요소로서 작용을 하고 있다.As the industry develops, it is inevitable to develop slopes such as mountain roads such as foundation roads and complexes. Currently, the sliding reality of slopes is constantly occurring regardless of time and place, and acts as a threat to life and property. Doing

이러한 이유에서 사면의 붕괴나 슬라이딩을 억제하기 위한 안정공법으로 가장 널리 이용되고 있는 것이 소일네일링(soil-nailing)공법이다.For this reason, the soil-nailing method is most widely used as a stabilization method for suppressing the collapse and sliding of the slope.

여기서, 소일네일링이라 함은 원지반에 보강재(네일구조체)를 설치하여 원지반 강도를 최대한 이용하면서 복합보강지반을 형성함으로써, 지반의 전단 및 인장강도를 증가시켜 변위를 억제시키고 지반의 이완을 방지시키는 공법이다.Here, the soil nailing is to install a reinforcement (nail structure) on the ground to form a composite reinforcement while maximizing the strength of the ground, thereby increasing the shear and tensile strength of the ground to suppress displacement and to prevent ground loosening It is a construction method.

즉, 소일네일링 공법의 기본 설계개념은 네일구조체에 의해 보강된 영역의 토괴가 마치 일체화된 옹벽과 같은 작용을 한다는 것에 의해 보강토 벽체가 가정할 수 있는 어떠한 경사면에 대해서도 안정을 유지한다는 것에 있는 것이다.In other words, the basic design concept of the soil nailing method is that the ingot of the area reinforced by the nail structure maintains stability on any slope that the reinforced earth wall can assume by acting as an integrated retaining wall. .

이러한 소일네일링은 가시설 흙막이 구조물, 기초 터파기 등에 사용되어 왔으나 근래에 들어 도로의 사면보강, 철도, 댐, 터널 갱구부 등의 암반보강 등 그 적용대상이 한층 넓어지고 있는 실정이다.Such small nailing has been used for temporary earthquake structures, foundation burrows, etc., but in recent years, its application has been expanded to include slope reinforcement of roads, rock reinforcement of railways, dams, and tunnel shafts.

그러나, 이러한 소일네일링은 토반에 유용하게 발명된 것을 암반에 접목시킨 것인데, 각종 사면의 암반구조는 토반과 달라 절리가 많은 암반, 공동층이 많은 암반, 단층의 영향을 받아 열변질화 되어 취약한 암반, 발파의 영향으로 불연속면이 발달되어 모암과 분리된 암반등 많은 사면은 구조가 불안정하여 기존 네일구조체만으로 암반사면을 보강시키는 것은 무리가 따를 수 있는 문제점이 있다.However, this small nailing is to combine the invention that is useful to the soil bedrock, and the rock structure of the various slopes are different from the soil bed, the rock is a lot of joints, rock with a large number of co-layers, weakened due to heat deterioration under the influence of monolayer In addition, many slopes, such as rocks separated from the mother rock due to the development of discontinuities due to blasting, are unstable in structure, and reinforcement of rock slopes using only existing nail structures has a problem that can be followed.

이에 본 출원인은 간단한 공법 및 장치에 의해 네일선단이 시공시 모반에 정착되도록 하여 사면보강을 향상시키는 네일앵커(출원번호 10-2002-0072035)를 출원한 바 있다.The present applicant has applied for a nail anchor (application number 10-2002-0072035) to improve the slope reinforcement by allowing the nail tip to be fixed to the birthmark during construction by a simple method and device.

이것은 소일네일을 모반에 정착시키기 위하여 사면보강공사용 천공홀(미도시)에 지지고정되는 앵커블레이드(1)가 포함된 앵커몸체(2)와: 이 앵커몸체와 나사결합되는 나합부(3)를 갖는 네일(4)로서 이형철근과: 상기 나사결합에 의한 이 이형철근의 전진으로 상기 앵커블레이드(2)를 확장시키는 테이퍼몸체(5)로 이루어지고, 이 테이퍼몸체(5)를 전진시키기 위해 이형철근과 간섭되도록 이형철근의 외주와 테이퍼몸체(5)의 관통홀에 서로 맞물리는 테이퍼면(6)이 형성된 것이다.This includes an anchor body (2) including an anchor blade (1) that is fixed to a drill hole (not shown) for slope reinforcement for fixing the nail to the birthmark; and a screwed portion (3) screwed with the anchor body. And a deformed rebar as a nail 4 having: a tapered body 5 which extends the anchor blade 2 by advancing the deformed rebar by the screw coupling, and releases to advance the tapered body 5. A tapered surface 6 is formed to engage each other in the outer circumference of the deformed steel bar and the through hole of the tapered body 5 so as to interfere with the reinforcing bar.

또한, 이를 수행하기 위한 앵커몸체(2)에는 앵커블레이드(1)의 확장을 위해 굴복이 용이하게 유도하는 좁은 두께로 변형유도넥(7)이 형성되어 있으며, 네일(4)의 회전시 앵커몸체(2)의 회전이 방지되도록 천공홀에 압착되는 쐐기돌기(8)가 형성되어 있다.In addition, the anchor body (2) for performing this is formed with a deformation guide neck (7) in a narrow thickness to easily guide the bowing for expansion of the anchor blade (1), the anchor body during the rotation of the nail (4) A wedge 8 is pressed into the drilled hole so as to prevent rotation of (2).

이러한 네일앵커를 통해 간단한 시공으로 그라우팅 시공 전에 네일앵커가 모반에 정착되며, 앵커블레이드를 통해 정착력이 증가되어 사면보강력이 향상될 수 있는 것이 확인되었다.It was confirmed that the nail anchor is fixed to the birthmark before the grouting construction by simple construction through such a nail anchor, and the anchoring blade can increase the fixing force and improve the slope reinforcement.

따라서, 간단한 시공을 통한 사면보강공사가 수행되며, 뒤이어 고려될 수 있는 사항이 이러한 네일앵커의 생산성과 강성 보강 등의 기능향상이다.Therefore, the slope reinforcement work is carried out through a simple construction, and the matters that can be considered afterwards are functional enhancements such as productivity and rigidity reinforcement of the nail anchor.

예를 들어, 네일앵커의 제작 생산성을 더욱 향상시키기 위하여는 그 가공공정의 축소나 재료투입의 절감을 들 수 있다.For example, in order to further improve the production productivity of the nail anchor, it is possible to reduce the processing process and reduce the material input.

그러나, 상기 네일앵커의 이형철근의 치수나 재질 등은 규격화되어 있으므로, 생산성을 향상시키기 위하여는 그 가공공정의 개선이 요구된다.However, since the dimensions, materials, and the like of the deformed rebar of the nail anchor are standardized, improvement of the processing process is required to improve productivity.

또한, 상기 네일(4)과 테이퍼몸체(5)의 간섭을 제공하는 테이퍼면(6)은 연장된 면을 제공하여 절곡단면에 따른 굴복취약점을 보완시키고 있지만, 만약 이형철근의 굴복이 진행된다면 상기 테이퍼면에 이웃된 지점에서 굴복이 진행될 것으로, 이 부위는 강성취약점이 될 수 있는 우려가 있다.In addition, the tapered surface 6 providing interference between the nail 4 and the tapered body 5 provides an extended surface to compensate for the weakness of bowing according to the bent section, but if the bowing of the deformed steel is in progress, The yielding will proceed at a point adjacent to the tapered surface, and there is a concern that this part may become a rigid vulnerability.

이에 본 발명은 상기 문제점을 개선하기 위하여 안출된 것으로, 네일앵커 이형철근의 가공을 더욱 편리하게 하고, 결합부위의 강도를 더욱 보완하여 네일앵커의 생산성과 강성을 더욱 향상시킨 사면보강공사용 네일앵커를 제공함에 그 목적이 있는 것이다.Accordingly, the present invention has been made in order to improve the above problems, to make the nail anchor deformed reinforcing bar more convenient, and to further enhance the strength of the joint portion of the slope reinforcement nail anchor for further improving the productivity and rigidity of the nail anchor The purpose is to provide.

예시도면 도 3 내지 도 5 는 본 발명에 따른 사면보강공사용 네일앵커를 나타낸 설명도로서, 본 발명은 소일네일을 모반에 정착시키기 위하여 사면보강공사용 천공홀(9)에 지지고정되는 앵커블레이드(1)가 포함된 앵커몸체(2)와, 이 앵커몸체(2)와 나사결합되는 네일(4)로서 이형철근과, 상기 나사결합에 의한 이 이형철근의 전진으로 상기 앵커블레이드(1)를 확장시키는 테이퍼몸체(5)로 이루어지고, 이 테이퍼몸체(5)를 전진시키기 위해 이형철근과 테이퍼몸체(5)의 관통홀에는 서로 간섭되도록 맞물리는 테이퍼면(6)이 형성된 사면보강공사용 네일앵커에 있어서: 상기 네일(4)로서 강봉에 돌출턱(12)이 연속적으로 형성된 이형철근의 강봉(10)에 균일한 강성이 보유되게 강봉(10)의 외주연장선상으로 나합부(14)가 형성되고, 이 나합부(14)와 나사결합되는 나합관통홀(16)이 앵커몸체(16)에 형성됨과 더불어, 상기 테이퍼몸체(5)에는 상기 강봉(12) 외주면과 일체선상으로 연장된 단부를 갖는 네일(4)과 간섭되어 테이퍼몸체(5)가 앵커몸체(2)와의 나사결합시 전진되도록 간섭부(18)가 형성된 것을 특징으로 하는 사면보강공사용 네일앵커이다.Exemplary drawings Figures 3 to 5 are explanatory views showing a nail anchor for slope reinforcement according to the present invention, the present invention is anchor blade (1) that is fixed to the perforated hole for slope reinforcement for fixing the nail to the birthmark (1) Anchor body (2) including a), the nail (4) screwed with the anchor body (2) to expand the anchor blade (1) by the advance of the deformed reinforcement, and the deformed reinforcement by the screw coupling In the reinforcement nail anchor for tapered body (5), the tapered surface (6) having a tapered surface (6) is formed so as to interfere with each other in the through-holes of the deformed steel and the tapered body (5) to advance the tapered body (5) : The nail 4 is formed on the outer circumferential line of the steel bar 10 so as to retain uniform stiffness on the steel bar 10 of the deformed steel bar in which the protruding jaw 12 is continuously formed on the steel bar as the nail 4. Screw tube screwed with this screw 14 The barrel hole 16 is formed in the anchor body 16, and the tapered body 5 has a tapered body 5 because the tapered body 5 interferes with the nail 4 having an end extending in an integral line with the outer circumferential surface of the steel bar 12. Slope reinforcement nail anchor is characterized in that the interference portion 18 is formed so as to advance when screwing with the anchor body (2).

즉, 먼저 본 발명은 네일(4) 전체에 있어서 균일한 강성이 보유되게 네일에 균일한 직경이 유지되도록 한 것이며, 특히 앵커몸체(2)와 네일(4) 결합부에 부여되는 균일한 직경이다.That is, the present invention is to maintain a uniform diameter on the nail so as to maintain a uniform stiffness throughout the nail (4), in particular a uniform diameter applied to the anchor body 2 and the nail (4) coupling portion .

이를 기본조건으로 네일(4)과 앵커몸체(2)의 나사결합이 수행되어야 할 것이 또 다른 조건이며, 이러한 균일한 직경을 보유한 네일(4)과 테이퍼몸체(5)를 간섭시켜 네일(4)과 앵커몸체(2)의 나사결합으로 테이퍼몸체(5)를 전진시킬 것이 또 부가된 조건이다.Another condition is that the screwing of the nail 4 and the anchor body 2 should be performed as a basic condition, and the nail 4 having the uniform diameter interferes with the nail 4 and the taper body 5. It is an additional condition that the tapered body 5 is advanced by screwing together with the anchor body 2.

이를 달성하기 위하여, 먼저 네일(4)인 이형철근의 선단에 강봉의 외주선상에 연장되어 나합부(14)가 형성된다.In order to achieve this, first, the screw portion 14 is formed by extending on the outer circumferential line of the steel bar at the tip of the deformed rebar, which is the nail 4.

이형철근은 강봉(10)과 돌출턱(12)으로 이루어지며, 상기 돌출턱(12)은 이종부재의 결합, 예를 들어, 철근과 콘크리트의 결합을 위해 형성된 마찰부재이며, 후술되는 설명에서 상기 돌출턱(12)은 마찰부재와는 다른 역할을 하게 된다.The deformed reinforcing bar is made of a steel bar 10 and the protrusion jaw 12, the protrusion jaw 12 is a friction member formed for the coupling of dissimilar members, for example, the reinforcing bar and concrete, in the following description Protruding jaw 12 is to play a different role than the friction member.

상기 나합부(14)를 이루는 강봉(10)의 나사선은 일반적인 가공, 예를 들어 이형철근 간의 커플링 결합을 위해 수행되는 불림나사가공 등으로 수행될 수 있다.The screw thread of the steel bar 10 forming the screwing part 14 may be performed by a general screw, for example, a so-called screw process performed for coupling coupling between deformed bars.

이 나합부(14)와 나합되는 나합관통홀(16)이 앵커몸체(2)에 형성되며, 이에 의해 강봉(10) 직경의 연장되어 나사선이 형성되어 강봉(10)의 균일한 강성이 보유된다.A screw through hole 16, which is screwed with the screwed portion 14, is formed in the anchor body 2, thereby extending the diameter of the steel rod 10 to form a screw thread, thereby maintaining uniform rigidity of the steel rod 10. .

다음으로, 앵커몸체(2)와 이형철근이 나합되면서 그 전진력으로 테이퍼몸체(5)를 전진시켜 앵커블레이드(1)를 확장시켜야 하는데, 상기 나합부(14)가 강봉(10)에 연장되어 형성되므로, 종래와 같은 간섭부재인 테이퍼면의 형성을 기대할 수 없고, 이에 대체하는 간섭부(18)가 형성될 것이 필요한다.Next, as the anchor body 2 and the deformed steel are joined together, the tapered body 5 must be advanced by the forward force thereof to expand the anchor blade 1, and the threaded portion 14 is extended to the steel rod 10. Since it is formed, the formation of the tapered surface which is the conventional interference member cannot be expected, and it is necessary to form the interference portion 18 to replace it.

본 발명은 이 간섭부(18)에 따라 크게 두가지 실시예로 구분되며, 하나는 나사결합에 의한 간섭부이고, 다른 하나는 이형철근의 돌출턱을 이용한 간섭부이다.The present invention is largely divided into two embodiments according to the interference portion 18, one of which is an interference portion by screw coupling, and the other is an interference portion using a protruding jaw of a deformed steel bar.

먼저, 나사결합에 의한 간섭부를 예시도면 도 3 및 도 5 에 의거하여 좀 더 상세히 설명하면, 제 1 실시예로서 상기 간섭부(18)는 상기 테이퍼몸체(5)에 나합관통홀(20)이 형성되고, 이형철근의 강봉(10) 외주면에는 상기 나합부(14)에 연장되어 상기 나합관통홀(20)에 나합되는 테이퍼몸체 나합부(22)가 형성된 것을 특징으로 한다.First, the interference part by screw coupling will be described in more detail with reference to FIGS. 3 and 5. As a first embodiment, the interference part 18 includes a screw through hole 20 in the tapered body 5. The tapered body screwing portion 22 is formed on the outer circumferential surface of the steel bar 10 of the deformed steel bar and extends to the screwing portion 14 to be screwed into the screwing through hole 20.

이것은 테이퍼몸체(5)에 상기 나합부(14)에 나합되면서 관통되어 앵커몸체(2)의 나합관통홀(16)과 나합되기 위한 별도의 나합관통홀(20)이 형성되고, 상기 나합부(14)는 테이퍼몸체(5)와의 간섭을 위해 연장되어 테이퍼몸체 나합부(22)로서 형성되어 있다.It is penetrated into the tapered body 5 while being screwed to the screwed portion 14 to form a separate screwed through hole 20 to be screwed with the screwed through hole 16 of the anchor body 2, and the screwed portion ( 14 extends for interference with the tapered body 5 and is formed as a tapered body screwing portion 22.

따라서, 테이퍼몸체 나합부(22)의 끝선까지 테이퍼몸체(5)를 나합시키게 되면, 그 끝단에서 테이퍼몸체(5)는 이형철근에 고정되어 일체화 되고, 이 테이퍼몸체(5)가 고정된 네일(4)과 앵커몸체(2)를 나사결합하며, 그 결합은 앵커블레이드(1)가 확장되기 전의 위치에 고정한다.Therefore, when the tapered body 5 is screwed to the end of the tapered body screwing portion 22, the tapered body 5 is fixed to the deformed reinforcing bar at the end thereof, and is integrated with the nail (to which the tapered body 5 is fixed). 4) and the anchor body (2) is screwed, the coupling is fixed to the position before the anchor blade (1) is expanded.

따라서, 상기 돌출턱(12)과 간섭턱(28)은 종래의 테이퍼면을 대체하며 그 결합은 종래와 마찬가지이다.Thus, the projection jaw 12 and the interference jaw 28 replace the conventional tapered surface and the combination thereof is the same as before.

즉, 네일(4)을 테이퍼몸체(5)에 관통시키고 그 선단의 나합부(14)를 앵커몸체(2)와 결합하고, 이때 그 결합은 앵커블레이드(1)가 확장되기 전의 위치에 고정한다.That is, the nail 4 is penetrated through the tapered body 5 and the screwed portion 14 of the tip thereof is coupled with the anchor body 2, and the coupling is fixed at the position before the anchor blade 1 is expanded. .

다음으로, 이것을 천공홀(9)에 삽입하고 네일(4)을 회전시키게 되면 그 나합에 의해 테이퍼몸체(5)가 전진되면서 앵커블레이드(1)가 확장되어 모반에 정착되는 것이다.Next, when this is inserted into the drilling hole 9 and the nail 4 is rotated, the tapered body 5 is advanced by the screwing, and the anchor blade 1 is expanded to be fixed to the birthmark.

상술된 바와 같이 본 발명에 따르면 강봉의 외주면과 동일선상으로 나합부가 형성되어 강봉의 균일한 강성이 보유될 수 있는 것이며, 테이퍼면의 가공에 비해, 간섭부의 가공이 용이한 것으로, 그 공정의 용이성에 따른 네일앵커의 생산성이 향상되는 효과를 얻게 된다.As described above, according to the present invention, a screwed portion is formed in the same line as the outer circumferential surface of the steel rod, so that uniform rigidity of the steel rod can be retained, and the processing of the interference portion is easier than that of the tapered surface. The productivity of the nail anchor is improved according to the ease.
