Description

시트파일 제조장치 및 그에 따른 시트파일{Steel sheet pile manufactory and accordingly steel sheet pile}Sheet pile manufacturing apparatus and sheet pile accordingly {Steel sheet pile manufactory and accordingly steel sheet pile}

본 고안은 시트파일 제조장치 및 그에 따른 시트파일에 관한 것으로, 보다 상세하게는 토목·건축 공사에서 지반에 타설하여 흙막이, 물막이 등을 포함하는 막이용으로 사용되는 시트파일 제조장치 및 그에 따른 시트파일에 관한 것이다.The present invention relates to a sheet pile manufacturing apparatus and a sheet pile according thereto, and more particularly, to a sheet pile manufacturing apparatus and sheet file according to the ground used in civil engineering and construction works used for membranes including soil, water, etc. It is about.

일반적으로 시트파일은 토목·건축 공사에서 물막이·흙막이 등을 위해 박는 강판으로 된 말뚝으로서, 수압 및 토압에 의한 휨이 방지되도록 단면형상이 절곡형성되고, 연속하여 설치되는 시트파일은 단부를 용접 혹은 나사결합 등의 체결수단으로 서로 결속하게 된다.Generally, the pile pile is a steel plate piled for water or soil in civil engineering and construction work, and the cross section is bent to prevent bending due to water pressure and earth pressure. It is bound to each other by a fastening means such as screwing.

예컨대, 시중에 유통되는 대부분의 시트파일이 규격화된 길이 및 폭, 절곡형상으로 제작됨에 따라 시공구간의 폭과 하중 등의 시공조건을 고려하여 그에 적합한 시트파일을 수량구매하여 시공하게 된다.For example, as most sheet piles in the market are manufactured in a standard length, width, and bend shape, the sheet piles are purchased in quantity in consideration of construction conditions such as width and load of construction sections.

하지만, 토목·건축 기초공는 환경적 변화가 다양하여 도로공사와 같은 소규모공사에서부터 해양교량건설과 같은 대규모의 공사에 이르기까지 그 범위가 매우 광범위하나, 규격화된 시트파일의 사용으로 인하여 연속시공후 시공범위를 벗어날 경우 절단하여 폐기하거나 겹쳐지도록 시공하므로 재료비손실로 인해 시공원가상승을 초래하였다.However, civil engineering and construction foundations vary widely in environment, ranging from small-scale construction such as road construction to large-scale construction such as offshore bridge construction.However, due to the use of standardized sheet piles, the scope of construction after continuous construction If it escapes, it is cut and discarded or overlapped, resulting in an increase in city park due to material cost loss.

뿐만 아니라, 해양교량건설과 같이 대규모 토목공사 현장에서 수십미터에서 수백미터에 걸쳐 물막이를 위한 시트파일을 설치해야함에도 불구하고, 시트파일의 폭이 1m이하의 소형사이즈로 규격화되어 생산됨에 따라 시트파일의 설치개수가 증가됨은 물론 시트파일간에 접합해야 할 부분이 함께 증가되어 공사기간이 지연되는 폐단이 따랐다.In addition, despite the need to install sheet piles for water barriers from tens of meters to hundreds of meters in large-scale civil engineering works such as offshore bridge construction, the width of sheet piles has been reduced to 1m and smaller. In addition to the increase in the number of installations, the parts to be joined between the seat piles increased together, resulting in a delay in the construction period.

이에 따라 본 고안은 상기한 문제점을 해결하기 위해 착안 된 것으로서, 보다 상세하게는 시트파일의 시공에 따른 작업성 및 공사기간을 단축시키고, 불필요한 재료비의 추가 손실을 방지하여 시공원가절감을 도모하기 위한 시트파일 제조장치 및 그에 따른 시트파일을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention was conceived to solve the above problems, and more specifically, to reduce the workability and construction period due to the construction of the sheet pile, and to prevent the additional loss of unnecessary material costs, thereby promoting city park reduction.

Located adjacent to the rollers 30 and 30 ', the steel sheet S is bent to form a recessed arch portion S2 as shown in FIG. 1A, and then, when the steel sheet S enters a half position, 1 As shown in (b), the roller 30 'positioned at the rear of the lower roller 30 in the lowered state is lifted and disposed in a triangular structure with the pair of upper rollers to protrude the arch portion S1. Will form.

그리고, 절곡각도 및 강판의 두께, 길이에 따라 상부롤러(20)(20')와 하부롤러(30)(30') 사이의 간격 및 이격거리가 제어박스에 의해 자동으로 조절되어 원하는 사이즈의 시트파일을 제조하게 된다.And, according to the bending angle and the thickness and length of the steel sheet, the distance and the separation distance between the upper rollers 20, 20 'and the lower rollers 30, 30' is automatically adjusted by the control box to the sheet of the desired size. The file will be manufactured.

이처럼, 돌출아치부(S1)와 함몰아치부(S2)로 구성된 시트파일이 상기한 바와 같이 단일의 절곡공정을 통하여 가공됨에 따라 생산성이 크게 향상되는 이점이 있다.As such, as the sheet pile composed of the protruding arch portion S1 and the recessed arch portion S2 is processed through a single bending process as described above, the productivity is greatly improved.

한편, 시트파일의 사이즈에 따라 강판(S)의 투입위치 및 배출위치가 가변되도록 공급ㆍ배출컨베이어(10)(40)의 높낮이를 조절하기 위한 실린더가 추가로 더 구비되는 것이 바람직하다.On the other hand, it is preferable that a cylinder for adjusting the height of the supply / discharge conveyors 10 and 40 is further provided so that the input position and the discharge position of the steel sheet S may vary according to the size of the sheet pile.

상기한 시트파일 제조장치를 통하여 제조된 시트파일은 단면형상이 강판(S)의 중심을 기준으로 일측은 볼록하게 돌출된 돌출아치부(S1)와, 다른 일측은 오목하게 함몰된 함몰아치부(S2)로 형성된다. 이에 시트파일을 흙막이, 물막이 등을 포함하는 막이용으로 지반에 시공시 돌출아치부(S1)와 함몰아치부(S2)가 힘살역할을 수행하여 수압 및 토압에 의해 쉽게 휘어지는 문제점이 해소된다.The sheet pile manufactured by the sheet pile manufacturing apparatus has a cross-sectional shape projecting arch portion S1 protruded convexly based on the center of the steel sheet S, and a recessed arch portion recessed in the other side ( S2). In this case, the projected arch portion S1 and the recessed arch portion S2 act as a force force when the sheet pile is used for the construction including the soil barrier, the water barrier, and the like, and thus the problem of being easily bent by water pressure and earth pressure is eliminated.

본 고안에 따른 변형예로서, 상기 돌출아치부(S1)와 함몰아치부(S2)는 단부에 절곡판(S3)이 형성되고, 절곡판(S3)은 상호 역방향으로 절곡형성된다. 절곡판(S3)은 별도의 프레스장치를 사용하여 돌출아치부(S1)와 함몰아치부(S2)의 단부를 도 3a처럼 절곡하여 형성하고, 이때 절곡판(S3)는 평판 혹은 후크형태로 절곡되어 시트파일을 연속적으로 시공시 도 3b와 같이 서로 맞물려 결속력이 향상된다. As a modification according to the present invention, the protruding arch portion S1 and the recessed arch portion S2 are formed at the end with a bending plate S3, and the bending plate S3 is bent in a reverse direction to each other.
