Description

흙막이 지지용 고강도 파일{A high-altitude file for surpporting the earth wall}A high-altitude file for sur- porting the earth wall,

본 발명은 흙막이 지지용 파일에 관한 것으로서, 보다 구체적으로는 터파기를 진행하기 위하여 시공된 흙막이 토류벽체를 지지해 주는 띠장이나 버팀보 등으로 사용되는 흙막이 지지용 고강도 파일에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a file for retaining soil, and more particularly, to a high strength file for retaining soil that is used as a wale or strut to support an earth retaining soil wall constructed to advance a wave.

종래 대한민국 등록특허공보 제10-1520771호에 개시되어 있는 개가착시설을 위한 브이자형 강판이 부착된 철근콘크리트 합성형 에이치 파일은 항타에 의한 근입이 용이하고 철근콘크리트의 합성으로 휨 강성이 뛰어난 것으로 알려져 있으나, 흙막이 토류벽체의 시공용으로는 적합하지만 띠장이나 버팀보로는 사용할 수 없었고, 철근콘크리트를 합성하기 위한 거푸집을 사용해야만 하며 철근콘크리트를 양생해야만 하는 것이어서 제조비용과 시간이 많이 소요되는 등의 문제점도 있었다.It is known that the reinforced concrete composite type H-file having a V-shaped steel plate for an interlocking facility disclosed in Korean Patent Registration No. 10-1520771 is easily inserted by horseshoe and has excellent flexural rigidity due to the synthesis of reinforced concrete However, it is suitable for the construction of the earth retaining wall structure, but it can not be used as a wale or strut, and it is necessary to use a formwork for synthesizing the reinforced concrete, and it is necessary to cure the reinforced concrete, .

또한, 대한민국 등록특허공보 제10-1674576호에 개시되어 있는 합성 에이치 파일을 이용한 흙막이 공법에 사용되는 합성 에이치 파일도 파일 상단에 결합된 캡 부재에 파일 드라이버를 고정하여 지반에 용이하게 근입할 수 있도록 해 줄수는 있지만 흙막이 토류벽체의 띠장이나 버팀보로는 사용할 수 없는 것이었다.In addition, a synthetic HIS file to be used in a retaining method using a synthetic HISP file disclosed in Korean Patent Publication No. 10-1674576 can also be used to fix a pile driver to a cap member coupled to the top of a file, But it could not be used as a wardrobe or stratum of the earthwalk.

그리고, 대한민국 등록특허공보 제10-1286396호에 개시되어 있는 가설용 변단면 에이치 파일은 길이방향으로 서로 다른 단면크기를 가지는 에이치 형강을 간편하게 연결시켜 줄 수 있도록 한쌍의 웨브 가이드 플레이트를 가지고, 소켓형 연결장치를 포함하는 것으로 흙막이 토류벽체를 시공하는데 사용될 수 있을 뿐 흙막이 토류벽체의 띠장이나 버팀보로는 사용할 수 없는 것이었다.In addition, the hypothetical cross-sectional H-ACT file disclosed in Korean Patent Publication No. 10-1286396 has a pair of web guide plates for easily connecting H-shape steel having different cross sectional sizes in the longitudinal direction, It can be used to construct the earth retaining wall structure by including the connecting device, and it can not be used as a welt or strut of the earth retaining wall structure.

또한, 종래의 흙막이 지지용 파일은 도 4에서 점선으로 도시되어 있는 바와 같이 강도가 부족한 것이어서 흙막이 토류벽체를 지지해 주는 띠장(a)이나 버팀보(b)로 사용하는 경우 많은 량의 띠장(a)과 버팀보(b)를 좁은 간격으로 설치해주어야만 했었기 때문에 시공비용이 많이들고, 시공기간이 길어지며, 터파기된 바닥으로 중장비를 이동시켜 주거나 이를 사용하여 작업하는 것에 많은 제약이 뒤따르는 등의 문제점이 있었다.In addition, as shown in FIG. 4, the conventional retaining pile has insufficient strength, so that when the retention wall is used as a wale (a) or a strut (b) for supporting the retaining wall, (B) have to be installed at a narrow interval. Therefore, the construction cost is increased, the construction period is lengthened, and the heavy equipment is moved to the floored floor, .

그리고, 종래 HPS 공법을 이용한 가시설 흙막이로 알려진 파일은 강관외측에 플랜지, 웹을 보강하여 개방형 횡단면을 갖는 에이치형강과 폐단면을 갖는 강관의 장점을 조합한 것이어서 구조적 강도가 커서 종래의 강관버팀보나 에이치 형강 버팀보에 비하여 최대 좌굴깊이를 증대시켜주고, 중앙말뚝 감소로 작업공간 확보가 용이한 장점이 있는 반면에 원형단면을 갖는 강관의 외측에 플랜지, 웹을 정확하게 용접하려면 고가의 대형제조 설비와 많은 제조공정과 많은 시간이 소요되어 비용이 많이들고 품질이 균일하게 대량생산 하기에 적합하지 않은 등의 문제점이 있었다. Also, a file known as a temporary cladding using a conventional HPS method is a combination of the advantages of H-shaped steel having an open cross-section and a steel pipe having a closed end surface by reinforcing a flange and a web outside the steel pipe, It has the advantage of increasing the maximum buckling depth as compared to the section steel bracket, and it is easy to secure the work space by reducing the center pile. However, in order to accurately weld the flange and the web to the outside of the steel tube having a circular cross section, It takes a long time to process and it is costly and the quality is not suitable for uniform mass production.

본 발명의 목적은 비교적 가격이 저렴하며 취급과 용접이 용이한 개방형 횡단면을 갖는 에이치형강을 기초로 하여 에이치형강의 웹과 플랜지들 사이에 보강부재를 마련하고 폐단면을 갖도록 마감함으로써 고강도를 발휘하며 보다 저렴한 비용으로 품질이 균일하게 대량생산할 수 있는 흙막이 지지용 고강도 파일을 제공하는데 있다.It is an object of the present invention to provide a reinforcement member between a web and flanges of a H-section steel and to finish with a closed end surface on the basis of H-section steel having a relatively low price and an open cross- Strength file for retaining soil that can be mass-produced uniformly in quality at a lower cost.

상기한 목적을 달성하기 위하여 본 발명은 에이치형강의 웹으로 양분되는 플랜지쪽 공간부 속에 연속되는 파형횡단면을 갖는 파형보강부재가 용접으로 고정되어 있으며, 상기 파형보강부재의 외측에는 상기 플랜지의 폭방향쪽 단부와 동일평면을 이루는 판상마감부재가 용접으로 고정되어 있고, 상기 에이치형강의 양단부가 이 양단부와 동일평면을 이루도록 절곡되어 있으며 용접으로 고정되는 상기 파형보강부재의 양측절곡단부로 폐쇄되어 있는 것을 기술적 요지로 한다.In order to attain the above object, the present invention is characterized in that a corrugated reinforcing member having a corrugated transverse cross section continuous to a flange-side space portion divided into a web of H-shape steel is fixed by welding, and on the outer side of the corrugated reinforcing member, And both end portions of the H-shaped steel are closed by both bent end portions of the corrugated reinforcing member which is bent so as to be flush with the both end portions and fixed by welding It is technically essential.

또한, 본 발명은 상기 판상마감부재에 하중분산 및 균열방지구멍이 형성된 것을 기술적 요지로 한다.Further, the present invention is characterized in that load distribution and crack preventing holes are formed in the plate finishing member.

이상 설명한 본 발명에 의한 흙막이 지지용 고강도 파일은 개방형 단면을 가진 에이치형강의 양측 및 단부쪽 공간부가 파형보강부재와 판상마감부재 및 상기 파형보강부재의 양측 절곡단부로 폐쇄형 단면을 갖는 구조로 이루어진 것이기 때문에 구조적 강도와 형태안정성 및 내하중성 그리고 내구성이 종래의 파일에 비하여 크게 향상시켜 줄 수 있어 터파기 공사현장에서 띠장이나 버팀보로 적용하는 경우 이들의 설치간격을 보다 더 넓혀줄 수 있게 되어서 파일의 사용 갯수를 감소시켜 주면서도 보다 견고하게 흙막이 토류벽을 지지해 줄 수 있게 되므로 공사비용과 시공기간을 크게 절감, 단축시켜줄 수 있을 뿐만 아니라 각종 중장비의 원활한 투입과 작업공간을 확보할 수 있으며, 안정성을 크게 향상시켜 산업재해를 예방할 수 있고, 보다 저렴한 비용으로 품질이 균일한 고강도 파일을 대량생산할 수 있는 등의 장점도 있다.The high-strength pile for retaining earth according to the present invention as described above has a structure in which both side and end side space portions of the H-shaped steel having an open cross-section have a closed cross-section by a corrugated finishing member and both bent ends of the corrugated reinforcing member The structural strength, shape stability, load-proofness and durability can be greatly improved as compared with the conventional file. Therefore, when the structure is applied as a wale or strut in a construction site, it is possible to widen the installation interval of the file. It is possible to support the earth retaining walls in a more rigid manner while reducing the number of use, thereby greatly reducing or shortening the construction cost and the construction period, securing the smooth installation of various heavy equipment and securing the work space, To prevent industrial accidents, It is possible to mass-produce high-strength files with uniform quality at a cost.
