일반적으로 보강토 옹벽은 도1에 도시된 바와 같이 전면판(11), 보강재(12), 뒤채움 흙으로 구성되는데, 여기서 보강토 옹벽의 벽체를 구성하는 전면판(11)은 뒷채움 흙의 유실을 방지하고, 보강재(12)를 연결시키며, 구조물의 외관상 시각적 효과를 높혀 주는 기능을 한다. 일반적으로, 전면판(11)의 종류로는 프리캐스트 콘크리트 판(Precast Concrete Panel), 금속재 전면판, 그리고 합성수지 전면판과 같은 것이 있다.In general, the reinforcement earth retaining wall is composed of the front plate 11, the reinforcement 12, the backfilling soil, as shown in Figure 1, wherein the front plate 11 constituting the wall of the reinforcement earth retaining wall to prevent the loss of backfilling soil And, connecting the reinforcing material 12, and serves to increase the visual effect of the structure. In general, types of the front plate 11 include a precast concrete panel, a metal front plate, and a synthetic resin front plate.
또한, 보강토 공법에 사용되는 보강재(12)는 지반의 인장강도를 보강하기 위해 사용되며, 보강재(12)는 지반과의 접촉면에서의 마찰력에 의해 인발에 대하여 저항함으로써, 그 기능이 이루어진다. 이러한 보강재(12)의 종류로는 일반적으로 토목 섬유 보강재, 스트립 형태의 보강재, 그리고 강재 보강재 등이 있다. 이러한 보강재(12) 중 본 발명은 강재 보강재를 개량한 것이다.In addition, the reinforcing material 12 used in the reinforcement earth method is used to reinforce the tensile strength of the ground, the reinforcing material 12 by the frictional force on the contact surface with the ground, the function is achieved. Types of such reinforcement 12 are generally geotextile reinforcement, strip-shaped reinforcement, and steel reinforcement. Of these reinforcement 12, the present invention is an improvement of the steel reinforcement.
도1에 도시된 일반적인 보강토 옹벽에 있어서, 보강토 옹벽의 안정성은 뒷채움부의 예상 파괴면 뒤에 위치한 길이
그러므로, 충분한 마찰력을 확보하기 위해서는 강재 보강재의 폭을 넓게 하고 유효길이(
따라서, 본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 본 발명은 강재 보강재의 양 측면을 절곡하여 요철 형태로 다수개의 돌출부를 형성함으로써, 보강재의 인발저항력을 크게 향상시킨 보강토 옹벽용 보강재를 제공하는데 그 목적이 있다.Therefore, the present invention has been made in order to solve the problems of the prior art as described above, the present invention by bending both sides of the steel reinforcement to form a plurality of protrusions in the form of concave-convex, reinforcement to significantly improve the pull resistance of the reinforcement The purpose is to provide a reinforcement for the retaining wall.

상기 목적을 달성하기 위한 본 발명은 지반 보강용 강재 보강재에 있어서, 상기 강재 보강재의 길이 방향의 양측면이 요철 형태의 다수개의 돌출부가 형성된 것을 특징으로 한다.The present invention for achieving the above object is characterized in that in the steel reinforcing material for ground reinforcement, both side surfaces in the longitudinal direction of the steel reinforcing material is formed with a plurality of protrusions of the uneven shape.
이하, 첨부된 도2 이하를 참조하여 본 발명의 실시예를 상세히 설명하기로 한다.Hereinafter, embodiments of the present invention will be described in detail with reference to FIG. 2.
도2는 본 발명에 따른 개량된 보강토 옹벽용 강재 보강재의 외관도로서, 13은 강재 보강재, 14는 돌출부를 각각 나타낸다.2 is an external view of an improved reinforcement earth retaining wall steel reinforcement according to the present invention, 13 is a steel reinforcement, 14 is a projection.
본 발명의 출원인은 일반적으로 흙과 보강재 사이의 마찰이 흙의 내부 마찰각보다 작아 흙과 접할 수 있는 부분이 있으면 마찰 저항이 커진다는 점에 착안하여 본 발명의 개량된 강재 보강재를 개발하였다.Applicants of the present invention have developed the improved steel reinforcement of the present invention in the light of the fact that the friction between the soil and the reinforcing material is less than the internal friction angle of the soil, the frictional resistance increases if there is a part that can contact the soil.
즉, 도2에 도시된 바와 같이 일반적인 강재 보강재(13)의 길이 방향의 양 측면이 요철 형태가 되도록 다수개의 돌출부(14)를 형성한다. 이와 같이 강재 보강재(13)의 길이 방향의 양 측면에 요철 형태의 돌출부(14)들을 형성하면 돌출부와 돌출부 사이에 흙이 체워져 결국 흙과 흙이 접촉되므로 이때의 마찰 저항은 요철이 없는 경우의 마찰저항보다 훨씬 커지게 된다.That is, as shown in FIG. 2, a plurality of protrusions 14 are formed such that both side surfaces of the general steel reinforcement 13 in the longitudinal direction are in the form of irregularities. As such, when the protrusions 14 having concave-convex shapes are formed on both side surfaces of the steel reinforcement 13 in the longitudinal direction, the soil is filled between the protrusions and the protrusions, and thus the soil and the soil are in contact with each other. It is much larger than the frictional resistance.
도2에 도시된 본 발명의 강재 보강재의 요철 형태는 직각을 이루도록 성형된 것이지만, 이와 같은 요철 형태는 동일한 목적을 이루면서도 다양한 형태를 가질 수 있다는 것은 자명한 것이므로, 본 발명의 권리 범위가 도면에 도시된 것에 한정되는 것은 아니다.Although the uneven form of the steel reinforcement of the present invention shown in Figure 2 is formed to form a right angle, it is obvious that such uneven form can have a variety of forms while achieving the same purpose, the scope of the present invention in the drawings It is not limited to what is shown.
도3은 본 발명에 따른 강재 보강재의 돌출부를 변형하여 인발저항력을 더욱 향상시킨 것이다.Figure 3 is to further improve the pull resistance by modifying the protrusion of the steel reinforcement according to the present invention.
도3에서 볼 수 있는 바와 같이 전면판 방향의 강재 보강재의 각 돌출부 전단을 강재 보강재의 평면과 수직 방향으로 소정의 각을 이루도록 형성하였다. 이와 같이 보강재를 형성할 경우 보강재의 인발저항력은 더욱 향상된다.As shown in FIG. 3, the front end of each protrusion of the steel reinforcement in the front plate direction was formed to have a predetermined angle in a direction perpendicular to the plane of the steel reinforcement. When the reinforcing material is formed in this way, the pullout resistance of the reinforcing material is further improved.
상기와 같이 이루어지는 본 발명의 효과를 살펴보면 아래와 같다.Looking at the effects of the present invention made as described above are as follows.
본 발명의 강재 보강재는 보강재의 양 측면을 요철 형태로 다수개의 돌출부를 형성함으로써, 보강재의 인발저항력이 크게 향상되고, 보강재의 측면에 요철모양을 만드는 작업은 공정이 비교적 단순하고 연속적이므로 자동화 할 수 있어서 보강재 제작단가는 크게 상승되지 않으며 보강재 소요 단면적이 감소하여 재료소비가 적고 보강재의 중량이 줄어서 취급이 용이하므로, 경제적이고 보강성이 탁월한 효과가 있다.Steel reinforcement of the present invention by forming a plurality of protrusions on both sides of the reinforcement in the form of irregularities, the pullout resistance of the reinforcement is greatly improved, the operation of making the irregularities on the side of the reinforcement can be automated because the process is relatively simple and continuous In this case, the manufacturing cost of the reinforcing material is not greatly increased, and the required cross-sectional area of the reinforcing material is reduced, so that the material consumption is low and the weight of the reinforcing material is reduced, so that it is easy to handle, so it is economical and has excellent reinforcing effect.
