본 발명은 벽강관 말뚝의 광폭형 이음새에 관한 것으로서, 특히 벽강관의 일측 또는 타측에 U형 리브를 용접한 후 이음새를 형성함으로써 벽강관 사이의 연결 폭을 대폭 증가시킴으로써 벽강관 말뚝의 소요 개수를 감소시킴에 따라서 시공 공 기가 단축되고 공사비 등이 절감되는 효과를 갖는 벽강관 말뚝의 광폭형 이음새에 관한 것이다. The present invention relates to a wide type seam of the wall steel pipe pile, in particular, by welding the U-shaped ribs on one side or the other side of the wall steel pipe to form a seam, thereby greatly increasing the connection width between the wall steel pipe pile required number of The present invention relates to a wide type joint of a wall steel pipe pile having an effect of shortening construction air and reducing construction cost according to the reduction.

일반적으로 벽강관 말뚝의 이음새는 벽강관 말뚝을 서로 연결하여 벽체를 형성할 때 연결고리 역할을 하는 것으로 지반에 항타되어 설치된 벽강관 말뚝에 의해 형성된 벽체는 차수(遮水) 및 토사유출(土沙流出)을 방지할 수 있다.In general, the joints of the wall steel pipe piles act as a connecting link when the wall steel pipe piles are connected to each other to form a wall. The wall formed by the wall steel pipe piles installed and driven on the ground has a degree of drainage and soil discharge. Can prevent the emergence.

종래의 벽강관 말뚝은 이음새의 형태에 따라 P-P형, P-T형, L-T형 등이 있으며, 이음새를 벽강관의 일측 또는 양측에 전길이에 걸쳐 용접하여 상호 연결될 수 있는 벽강관 말뚝으로 사용하였다. Conventional wall steel pipe piles are P-P type, P-T type, L-T type, etc. according to the shape of the seam, and the seams were used as wall steel pipe piles that can be interconnected by welding the entire length to one or both sides of the wall steel pipe.

도1에 예시된 바와 같이, P-P형 벽강관 말뚝은 주로 틈새가 있는 P형 이음새(2, 2a)인 개수관을 벽강관(1, 1a)에 각각 용접한 후 P형이음새(2, 2a)를 상호 결합하여 이를 연결하는 방식으로 시공하였다. As illustrated in Fig. 1, the PP-type wall steel pipe piles are mainly welded to the wall steel pipes 1 and 1a, respectively, to the P-shaped seams 1 and 1a, respectively, with P-shaped seams 2 and 2a having a gap therebetween. It was constructed in such a way that they are connected to each other by connecting them.

도2에 예시된 바와 같이, P-T형 벽강관 말뚝은 P형 이음새(4)인 개수관과 T형 이음새(4a)인 T형 바를 벽강관(3,3a)에 각각 용접하여 이를 결합시켜 상호 연결하는 방식으로 시공하였다.As illustrated in FIG. 2, the PT-type wall steel pipe piles are connected to each other by welding the water pipes of the P-shaped seams 4 and the T-shaped bars of the T-shaped seams 4a to the wall steel pipes 3 and 3a, respectively. It was constructed in the way.

도3에 예시된 바와 같이, L-T형 벽강관 말뚝은 벽강관(5, 5a)에 ㄱ형강을 용접하여 L형 이음새(6)를 형성하고 T형 바를 용접하여 T형 이음새(6a)를 형성한 후 상호 결합시켜 연결하는 방식으로 시공하였다.As illustrated in FIG. 3, the LT-type wall steel pipe pile is formed by welding the a-beam to the wall steel pipes 5 and 5a to form the L-shaped joint 6, and by welding the T-shaped bar to form the T-shaped joint 6a. It was then constructed by coupling to each other.

이와 같은 기존의 벽강관 말뚝 구조체는 강널말뚝(물막이 흙막이 등을 위해 강판으로 된 말뚝)에 비해 단면성능이 뛰어나 구조적으로 우수한 연결구조이나 개수관의 틈새를 절단하는 공정과, 개수관, T형바, ㄱ형강으로 이루어진 이음새를 벽 강관에 용접하는 공정이 추가적으로 필요하였다. This conventional wall steel pipe pile structure has a superior cross-sectional performance compared to steel sheet piles (a pile made of steel sheet for water barriers, etc.), and has a structurally superior connection structure or a process of cutting gaps in water pipes, water pipes, T-shaped bars, An additional process of welding seams consisting of a-beams to wall steel pipes was needed.

또한, 이러한 용접공정들은 대부분 수작업으로 이루어지므로 시간이 많이 소요되었을 뿐만 아니라 비용도 많이 드는 단점이 있었다.In addition, these welding processes are not only time-consuming but also costly because they are mostly made by hand.

아울러, 벽강관의 이음새 폭이 벽강관의 폭에 비해 작아서 다수의 벽강관을 사용하여야 하므로 시공시간이 많이 소요되는 문제점이 있었다.In addition, since the seam width of the wall steel pipe is smaller than the width of the wall steel pipe, a large number of wall steel pipes must be used.

본 발명은 상기의 종래 문제점을 개선하기 위해 개발된 것으로서, 본 발명의 목적은 벽강관 말뚝 이음새의 개수를 감소시킬 수 있는 벽강관 말뚝의 광폭형 이음새를 제공하고자 하는 것이다.The present invention was developed to improve the above-mentioned conventional problem, and an object of the present invention is to provide a wide type of seam pipe piles that can reduce the number of wall pipe pile seams.

본 발명의 다른 목적은 기존의 강관 말뚝 이음새의 간격을 크게 증가시킬 수 있는 벽강관 말뚝의 광폭형 이음새를 제공하고자 하는 것이다.Another object of the present invention is to provide a wide seam of the wall steel pipe pile that can greatly increase the spacing of the existing steel pipe pile seams.

본 발명의 더욱 다른 목적은 시공 공기를 단축시키고 시공비를 감소시킬 수 있는 벽강관 말뚝의 광폭형 이음새를 제공하고자 하는 것이다.A further object of the present invention is to provide a wide seam of wall pipe piles which can shorten the construction air and reduce the construction cost.

본 발명의 이와 같은 목적은 벽강관(10, 10a)과, This object of the present invention is the wall steel pipe (10, 10a),

이 벽강관(10,10a)의 양측 대향위치에 전체 길이방향으로 용접되어 돌출되는 U형 리브(11, 11a)와, U-shaped ribs 11 and 11a which are welded and protruded in the entire longitudinal direction at opposite sides of the wall steel pipes 10 and 10a, and

U형 리브(11, 11a)의 양측에 전체 길이방향으로 용접되어 벽강관(10, 10a)을 상호 연결시켜주는 이음새로 구성함으로써 달성된다.It is achieved by constructing a seam that is welded to both sides of the U-shaped ribs 11 and 11a in the entire longitudinal direction to interconnect the wall steel pipes 10 and 10a.

U형 리브(11, 11a) 양측에 각각 용접되는 이음새는 L형 이음새(13, 17)와 T 형 이음새(14, 18)로 각각 상이하게 구성되는 것이 바람직하다.The joints welded to both sides of the U-shaped ribs 11 and 11a are preferably composed of L-shaped joints 13 and 17 and T-shaped joints 14 and 18, respectively.

이와 달리, U형리브(11, 11a)의 양측에 용접되는 이음새는 L형 이음새(13) 또는 T형 이음새(14) 중 한 형태의 이음새 만으로 구성될 수도 있다.Alternatively, the seams welded to both sides of the U-shaped ribs 11 and 11a may consist of only one type of seam of the L-shaped seam 13 or the T-shaped seam 14.

상기와 같이 구성된 벽강관 말뚝의 광폭형 이음새는 L형 이음새(13)에 T형 이음새(18)를 상호 결합시켜 벽강관 말뚝이 연결되어 벽면형태를 이룸으로써 차수성을 갖는 구조물을 이룬다.The wide-type joint of the wall steel pipe piles configured as described above is coupled to the T-shaped seam 18 to the L-shaped seam 13 to form a structure having a water order by connecting the wall steel pipe piles to form a wall surface.

이하, 첨부도면을 참조하여 본 발명의 광폭형 벽강관 이음새를 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in more detail the wide-wall steel pipe joint of the present invention.

도4에 분해 사시도로, 도5에 결합평면도로, 도6에 확대도로 예시된 바와 같이, 본 발명의 벽강관 말뚝은 벽강관의 양측에 U형 리브가 돌출되어 형성되고, 돌출된 U형 리브에 다시 이음새가 형성되어 벽강관과 벽강관 사이의 연결부 폭이 종래에 비해 크게 확장된 것이 특징이다. 도면에서는 간략한 설명을 위해 상호 연결되는 벽강관의 일측에만 U형 리브가 돌출형성된 것으로 도시하였으나, 실제로는 양측에 U형리브가 설치된 것이다. As illustrated in the exploded perspective view in Figure 4, the coupling plan view in Figure 5, the enlarged view in Figure 6, the wall steel pipe pile of the present invention is formed by protruding U-shaped ribs on both sides of the wall steel pipe, the protruding U-shaped rib A seam is formed again, so that the width of the connection portion between the wall steel pipe and the wall steel pipe is greatly enlarged compared with the conventional art. In the drawings, for the sake of brevity, only one side of the mutually connected wall steel pipes is formed as protruding U-shaped ribs.

본 발명의 광폭형 벽강관 말뚝 이음새는 벽강관(10, 10a)과, 이 벽강관(10, 10a)의 양측에 전체 길이방향으로 용접된 U형 리브(11, 11a)와, 이 U형 리브(11, 11a)의 길이방향으로 L형 이음새(12) 및 T형 이음새(12a)를 각각 용접하여 L형 이음새(12)와 T형 이음새(12a)를 상호 결합시켜 연결할 수 있게 구성된다.The wide wall steel pipe pile joint of the present invention includes wall steel pipes 10 and 10a, U-shaped ribs 11 and 11a welded to both sides of the wall steel pipes 10 and 10a in the entire longitudinal direction, and the U-shaped ribs. The L-shaped seam 12 and the T-shaped seam 12a are welded in the longitudinal direction of (11, 11a), respectively, so that the L-shaped seam 12 and the T-shaped seam 12a are connected to each other.

미설명 부호 15, 15a, 16, 17은 U형 리브(11, 11a), L형 이음새(12), T형 이음새(12a)의 용접부이다.Reference numerals 15, 15a, 16, and 17 denote welding portions of the U-shaped ribs 11, 11a, the L-shaped seam 12, and the T-shaped seam 12a.

U형 리브(11)와 U형리브(11a)는 벽강관(10, 10a)의 양측에 각각 대칭으로 또는 비대칭으로 형성될 수 있다. 이는 대칭으로 U형리브가 형성된 후 이음새가 설치된 벽강관 말뚝을 상호 연결하여 일직선의 벽체를 형성하거나 비대칭으로 형성된 U형 리브에 이음새를 설치하여 소정 각도를 이루는 벽체의 연결부를 형성하기 위한 것이다.The U-shaped ribs 11 and the U-shaped ribs 11a may be formed symmetrically or asymmetrically on both sides of the wall steel pipes 10 and 10a, respectively. This is to form a wall of straight line by connecting the wall steel pipe piles with seams provided with symmetrical U-shaped ribs, or by installing seams on U-shaped ribs formed asymmetrically to form a wall at a predetermined angle.

본 발명의 광폭형 벽강관 말뚝 이음새는 벽강관(10, 10a)과 L형 및 T형 이음새(12, 12a) 사이에 U형 리브(11, 11a)를 각각 형성함으로써 벽강관 말뚝의 연결 폭이 종래의 이음새로 연결된 벽강관 말뚝 보다 더욱 크게 증대되므로 지반에 항타되어 벽체를 형성할 때 자연히 벽강관 말뚝의 사용 개수가 감소된다. The wide-walled pipe pile seams of the present invention are formed by forming U-shaped ribs 11 and 11a between the wall steel pipes 10 and 10a and the L- and T-shaped seams 12 and 12a, respectively, so that the connection width of the wall steel pipe piles is increased. Since the steel pipe pile is connected to a larger seam than a conventional seam, the number of use of the steel pipe pile is naturally reduced when the wall is driven to form a wall.

상기 벽강관 말뚝은 계속하여 상호 연결되도록 벽강관(10, 10a)의 일측에 L형 이음새(12)가 그리고 벽강관(10, 10a)의 타측에 T형 이음새(12a)가 용접되는 것이 바람직하다. 이와 달리 벽강관(10, 10a)의 양측에 L형 이음새(12) 또는 T형 이음새(12a)가 용접되어 상호 연결될 수 있다. 이들 이음새는 벽강관 말뚝의 일체성 및 차수성을 달성하기 위해 벽강관 길이방향으로 전체길이에 걸쳐 용접된다.The wall steel pipe pile is preferably welded to the L-shaped seam 12 on one side of the wall steel pipe (10, 10a) and the T-shaped seam (12a) on the other side of the wall steel pipe (10, 10a) to be continuously interconnected. . Alternatively, L-shaped seams 12 or T-shaped seams 12a may be welded to both sides of the wall steel pipes 10 and 10a to be interconnected. These seams are welded over the entire length of the wall steel pipe longitudinally to achieve integrity and orderability of the wall steel pipe piles.

이와 같이 벽강관의 길이방향으로 용접된 U형 리브(11, 11a)와 L형 이음새(12)에 T형 이음새(12a)가 용접되어 연결될 벽강관 사이의 폭이 크게 증대된 벽강관 말뚝의 이음새를 결합시켜 벽강관(10, 10a)이 상호 연결되게 함으로써 본 발명의 벽강관 말뚝의 광폭형 이음새에 의해 벽면형태를 이루어 항만구조물, 교각기초, 방파제 등의 다양한 지중벽체 또는 기초 구조물이 형성된다.Thus, the seam of the wall steel pipe pile which has greatly increased the width between the U-shaped ribs 11 and 11a welded in the longitudinal direction of the wall steel pipe and the T-shaped seam 12a to the L-shaped seam 12 to be welded and connected. By combining the wall steel pipe (10, 10a) to be interconnected to form a wall surface by the wide-type seams of the wall steel pipe pile of the present invention to form a variety of underground walls or foundation structures such as port structures, bridge foundations, breakwaters.

이하, 상기와 같이 구성된 본 발명의 벽강관 말뚝 광폭형 이음새의 설치작업 을 설명한다.Hereinafter, the installation work of the wall steel pipe pile wide type joint of the present invention configured as described above.

U형 리브(11, 11a)와 L형 이음새(12) 또는 U형 리브(11, 11a)와 T형 이음새(12a)가 벽강관(10, 10a)에 용접되어 이루어진 벽강관 말뚝을 지반으로 항타시켜 설치한다.The U-shaped ribs 11 and 11a and the L-shaped seam 12 or the U-shaped ribs 11 and 11a and the T-shaped seam 12a are welded to the wall steel pipes 10 and 10a. Install it.

그리고, 예컨대 L형 이음새(12)가 형성된 벽강관 말뚝이 지반으로 타입되어 설치된 경우, T형 이음새(12a)가 용접된 벽강관 말뚝을 L형 이음새(12)에 결합시켜 항타시킴으로써 벽강관 말뚝이 상호 연결되고, 이 벽강관의 타측에 용접된 L형 이음새(12)에 또다른 벽강관의 T형 이음새(12a)를 순차적으로 계속 연결함으로써 벽강관 말뚝이 벽면형태를 이루게 한다.And, for example, when the wall steel pipe pile formed with the L-shaped seam 12 is installed as a ground type, the wall steel pipe pile is interconnected by coupling the steel pipe pile welded by the T-shaped seam 12a to the L-shaped seam 12 to drive it. By continuously connecting the T-shaped seams 12a of another wall steel pipe to the L-shaped seams 12 welded to the other side of the wall steel pipe, the wall steel pipe piles form a wall shape.

이와 같이 구성되어 지반에 항타되어 연결되도록 설치된 벽강관 말뚝은 항만구조물, 교각기초, 방파제 등의 지중벽체 또는 기초 구조물을 연속적으로 형성할 수 있다.The steel pipe piles constructed as described above and installed to be driven and connected to the ground may continuously form underground walls or foundation structures such as port structures, bridge foundations, and breakwaters.

본 발명의 벽강관 말뚝의 광폭형 이음새는 통상의 벽강관 말뚝의 양쪽 대향 위치에 대칭으로 U형 리브를 용접하여 벽강관 말뚝의 이음새 폭을 크게 확장하여 벽강관의 사용 개수를 감소시키는 효과, 벽강관 말뚝 사용 개수의 감소에 따른 공기 단축효과, 및 시공비가 감소되는 효과는 물론 설치작업성이 개선된 효과를 갖는 유용한 발명이다.The wide seam of the wall steel pipe pile of the present invention is effective to reduce the number of use of the wall steel pipe by greatly expanding the seam width of the wall steel pipe pile by welding the U-shaped ribs symmetrically on both opposite positions of the conventional steel pipe pile It is a useful invention having the effect of reducing the air shortening effect, and the construction cost is reduced, as well as the installation workability is improved according to the number of steel pipe piles used.
