Description

축부재 연결부의 좌굴방지용 이중 소켓형 축부재 연결구조 및 연결방법{Double socket type shaft member connection structure and connection method for preventing buckling of shaft member connection part}Double socket type shaft member connection structure and connection method for preventing buckling of shaft member connection part}

본 발명은 축부재 연결부의 좌굴방지용 이중 소켓형 축부재 연결구조 및 연결방법에 관한 것으로, 특히 강관 버팀보 축부재 간의 연결강도를 높여 효과적으로 좌굴을 방지하고, 사용 후 해체도 용이한 축부재 연결부의 좌굴방지용 이중 소켓형 축부재 연결구조 및 연결방법에 관한 것이다.The present invention relates to a double socket-type shaft member connection structure and connection method for preventing buckling of shaft member connections, and in particular, by increasing the connection strength between steel pipe support shaft members, effectively preventing buckling, and buckling of shaft member connections that are easy to dismantle after use. It relates to a double socket type shaft member connection structure and connection method for prevention.

일반적으로 지중 철근 콘크리트 구조물을 시공하려면 해당 지반의 시공경계를 따라 일정한 간격으로 H빔을 설치하고, 인접한 H빔 사이에 토류판을 설치하면서 일정한 심도마다 띠장을 부착하여 H빔과 토류판을 안정시킨다.In general, in order to construct an underground reinforced concrete structure, H beams are installed at regular intervals along the construction boundary of the ground, and earth plates are installed between adjacent H beams, and wales are attached at regular depths to stabilize the H beams and earth plates.

마주보는 토류판의 띠장은 버팀보로 버티고, 코너측 띠장은 스트럽트로 보강하여 토류판 전체를 안정시킨다. The wale of the facing earth plate is supported by a buttress, and the corner side wale is reinforced with struts to stabilize the entire earth plate.

이때, 상기 띠장과 버팀보, 스트럽트의 소재는 H빔이다.At this time, the material of the wale, the strut, and the strut is an H-beam.

스트럽트는 띠장과 버팀보에 비해 짧은 게 일반적이므로 단척 H빔 2개를 연결하는 경우가 매우 드물지만, 특히 버팀보는 길이가 정해진 규격장의 H빔 1개로는 부족한 경우가 흔하다.Since struts are generally shorter than wales and braces, it is very rare to connect two short H-beams, but in particular, one H-beam of a standard length with a fixed length is often insufficient for struts.

이런 경우, 버팀보는 단면이 동일한 규격의 H빔을 필요한 길이가 되도록 연결한다.In this case, the struts connect H-beams of the same size to the required length.

연결은 특수 설계한 연결구에 H빔의 연결단을 끼우고 체결하거나, H빔의 양측 플랜지와 웨브의 안팎에 강판을 대고 체결하는 비용접식이다. The connection is a non-welding method in which the connection end of the H-beam is inserted into a specially designed connector and fastened, or the flange on both sides of the H-beam and the steel plate are applied to the inside and outside of the web.

등록특허 제10-0733719호와 등록특허 제10-0945049호, 공개실용신안 제20-2012-0006727호가 대표적인 데, 문제는 강판과 비체결식으로는 2개의 H빔을 좌굴되지 않도록 연결할 수 없다는 점이다.Registered Patent No. 10-0733719, Registered Patent No. 10-0945049, and Utility Model Publication No. 20-2012-0006727 are typical examples. The problem is that two H-beams cannot be connected without buckling by using a steel plate and non-joint type .

또, 지하구조물의 규모에 따라 띠장과 버팀보의 길이 변경이 불가피한 경우가 흔하며, 앞서 시공한 지하구조물 공사에 투입했다 철거한 띠장과 버팀보를 후시공 지하구조물 구축용 토류판에 재사용할 때 토류판의 설계장 보다 짧으면 덧붙여 길이를 맞추고, 길면 남는 부분을 절단하여 설계장에 맞춰야 한다. In addition, depending on the size of the underground structure, it is common to change the length of the wale and braces, and when the strips and braces removed after being put into the previously constructed underground structure are reused for the earth plate for the construction of the post-construction underground structure, the design of the earth plate If it is shorter, the length must be added, and if it is longer, the excess part must be cut to fit the design.

문제는 버팀보의 길이조정이 번거롭고, 별도의 비용도 발생하며, 연결용 강판과 H빔 연결단의 볼트-너트 체결개소가 많아 연결과 해체에 오랜 시간이 걸리는 문제가 있다.The problem is that it is cumbersome to adjust the length of the brace, additional costs are incurred, and there are many bolt-nut fastening places between the steel plate for connection and the H-beam connection end, so it takes a long time to connect and dismantle.

As shown in these drawings, the connecting ends of the two shaft members P1 and P2 having the same pipe diameter are butted in the axial direction, and the anti-buckling sheet 50 is covered on the outer surface of the connecting ends of the shaft members.

좌굴방지시트(50)는 원주방향측 양쪽 단부(51, 52)를 겹쳐서 틈을 없앤다.The anti-buckling sheet 50 overlaps both ends 51 and 52 in the circumferential direction to eliminate a gap.

이때, 좌굴방지시트(50)는 양측 축부재(P1, P2)의 연결단부가 절반씩 차지하도록 씌워서 균형을 맞춘다.At this time, the anti-buckling sheet 50 is balanced by covering the connecting ends of the shaft members P1 and P2 on both sides to occupy half of each.

상기 좌굴방지시트(50)의 중간에 복부소켓(10)을 씌우고, 오므려뜨린 상태에서 뿔(11, 12)을 포위하도록 테(30)를 씌운다.The abdominal socket 10 is covered in the middle of the anti-buckling sheet 50, and the frame 30 is covered so as to surround the horns 11 and 12 in a folded state.

이어서, 쐐기공(31)에 쐐기(40)를 박는다. Then, the wedge 40 is driven into the wedge hole 31.

쐐기(40)가 박히면서 그 쪽 뿔(12)을 반대편 뿔(11)쪽으로 밀어낸다. As the wedge 40 is driven, it pushes the horn 12 toward the opposite horn 11.

이에 복부소켓(10)이 축경되면서 좌굴방지시트(50)와 축부재(P1, P2)의 연결단부를 최대한 옥죈다. Accordingly, while the diameter of the abdominal socket 10 is reduced, the connecting ends of the anti-buckling sheet 50 and the shaft members P1 and P2 are clamped as much as possible.

그리고, 좌굴방지시트(50)의 양단부에 단부소켓(20(20a)을 씌우고, 상기한 바와 같은 방법으로 뿔(11a, 12a)에 테(30a)를 씌워 가둔 다음에 쐐기공(31)에 쐐기(40a)를 박아 단부소켓(20, 20a)을 옥죄면 2개의 축부재(P1, P2)는 좌굴되지 않도록 공고하게 연결된다.In addition, the end sockets 20 (20a) are covered on both ends of the anti-buckling sheet 50, and the horns 11a and 12a are covered with frames 30a in the same manner as described above, and then wedged in the wedge hole 31 When the end sockets 20 and 20a are clamped by driving (40a), the two shaft members P1 and P2 are firmly connected so as not to buckle.

사용 후 축부재(P1, P2)를 철거하고, 수송 또는 보관 편의를 고려하면 테(30, 30a)에서 쐐기(40, 40a)를 뽑아 분리한다. After use, the shaft members P1 and P2 are removed, and the wedges 40 and 40a are removed and separated from the frames 30 and 30a in consideration of transportation or storage convenience.
