Description

연결부 강성이 증대된 아이빔 세그멘트 가설교량 연결방법{I-beam segment construction bridge connection method which increased in junction stiffness}I-beam segment construction bridge connection method which increased in junction stiffness}

본 발명은 연결부 강성이 증대된 I빔 세그멘트 가설교량 연결방법에 관한 것이다.The present invention relates to a method for connecting an I beam segment temporary bridge with increased joint stiffness.

일반적으로 우회용 가설교량이나 공사용 가설교량을 건설함에 있어, 수십 년간 사용하고 있는 기존의 가설교량의 I빔 세그멘트 연결방법은 도 1 내지 도 3에 도시된 바와 같이, I빔 세그멘트(10)의 상부플랜지(12) 상면에 복공판(14)이 거치 정착되는 관계로 I빔 세그멘트(10)의 연결 접합부(16)에서 복공판(14)의 돌출방지와 수평면 유지를 위해 상부플랜지(12)는 연결강판(18)과 고장력볼트(32)에 의한 연결이 불가하여 상부플랜지(12) 상면을 현장에서 용접(24) 접합하는 실정이었다.In general, in constructing a bypass bridge for construction or a construction bridge for construction, the I beam segment connection method of the existing construction bridge that has been used for decades is, as shown in Figures 1 to 3, the upper portion of the I beam segment (10) The upper flange 12 is connected to the upper flange 12 in order to prevent the protrusion of the double hole plate 14 and to maintain a horizontal plane at the connection junction 16 of the I-beam segment 10 because the double plate 14 is mounted on the upper surface of the flange 12. 18) and the high tension bolt 32 was not possible to connect the upper flange 12, the upper surface of the welding (24) in the field.

이와 같이 기존의 가설교량 I빔 세그멘트 연결 접합부(16)의 상부플랜지(12)는 현장 용접(24)접합, 복부(20)와 하부플랜지(22)는 연결강판(18)으로 연결 접합하니 연결 강성이 취약하여 응력도에 따른 I빔 세그멘트(10) 접합부를 고려할 때 연결 접합부(16)가 미리 고정되어 있어 현장여건에 따른 가설교량(B)의 설치가 곤란하고, 통수단면 확보를 위한 장경간 I빔 세그멘트(10)의 가설교량(B) 건설에는 많은 제약이 있었다.As such, the upper flange 12 of the existing temporary bridge I beam segment connection joint 16 is joined by field welding 24, and the abdomen 20 and the lower flange 22 are connected by a connecting steel plate 18. In view of the weakness of the I-beam segment 10 joint according to the stress level, the connection joint 16 is fixed in advance, so that it is difficult to install the temporary bridge B according to the site conditions. There were many restrictions on the construction of the temporary bridge B of the segment 10.

또한, 연결 접합부(16)의 연결 강성의 취약점을 극복하기 위해서는 필요 이상의 강재량이 소요되어 비경제적인 요인도 상존하고 있는 실정이다.In addition, in order to overcome the weakness of the connection stiffness of the connection joint 16, the amount of steel more than necessary is required, and the economical factors exist.

그런데, 강재 가설교량(B) 공사비가 손료로서 계산되고, 반복 사용되어야 하는 강재 가설교량(B)의 특성상 I빔 세그멘트(10)를 손상 없이 해체하여야 재사용이 가능하나, I빔 세그멘트 해체시 연결접합부 상부플랜지(12)의 용접(24) 접합부위로 인해 부득이하게 상부플랜지(12) 접합부를 용접으로 절단 및 해체함으로 인한 강재손상으로 강재의 재사용률이 줄어들어 항상 비경제적인 요인이 상존하고 있다.By the way, the construction cost of steel temporary bridge (B) is calculated as a waste, and due to the characteristics of the steel temporary bridge (B), which must be used repeatedly, the I beam segment 10 must be dismantled without damage to reuse it. Due to the welding 24 of the upper flange 12 inevitably due to the steel damage due to the cutting and dismantling of the upper flange 12 by welding, the reuse rate of the steel is always reduced and there are always economic factors.

따라서, 설치 해체시 I빔 세그멘트(10)의 모재를 손상하지 않은 연결접합 방법이 절실히 요구되고, 또한 I빔 세그멘트(10)의 연결 접합부(16)에서 복공판(14)의 돌출방지와 수평면을 유지하면서도 연결접합 강성이 증대되어 응력도에 따른 연결 접합부(16)를 고려하지 않고, 연결부 개소를 증대하여 장경간을 확보할 수 있는 연결접합 방법이 필요한 실정이다.Therefore, there is an urgent need for a connection bonding method that does not damage the base material of the I-beam segment 10 when dismantling the installation, and also prevents the protrusion of the perforated plate 14 and the horizontal plane from the connection junction 16 of the I-beam segment 10. However, the connection bonding stiffness is increased, and a connection bonding method capable of securing a long span by increasing the connection portion without considering the connection joint 16 according to the stress level is required.

이에, 본 발명은 상기한 바와 같은 제문제점을 해결하기 위해 안출된 것으로서, 기존의 I빔 세그멘트의 연결 접합 강성을 유지할 수 있으면서 가설교량 I빔 세그멘트의 상부플랜지에 거치되는 복공판이 I빔 세그멘트의 연결 접합부에서 돌출되지 않고 수평면을 유지하면서, I빔 세그멘트 가설교량을 설치 해체시 I빔 세그멘트의 모재의 손상이 없도록 한 연결부 강성이 증대된 I빔 세그멘트 가설교량 연결방 법을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, the connecting plate of the perforated plate mounted on the upper flange of the temporary bridge I-beam segment can maintain the connection stiffness of the existing I-beam segment connection of the I-beam segment The object of the present invention is to provide a method of connecting I beam segment temporary bridges with increased rigidity of the joints to prevent damage to the base material of the I beam segment when dismantling the I beam segment temporary bridges while maintaining the horizontal plane without protruding from the joints.

상기한 목적을 달성하기 위한 본 발명에 따른 연결부 강성이 증대된 I빔 세그멘트 가설교량 연결방법은 I빔 세그멘트를 연결 접합하여 설치하는 가설교량에 있어서, 상기 I빔 세그멘트의 연결 접합부 부근의 복부 상단 좌우면에 일자형 강판 또는 각형 강판을 연결접합용 보조플랜지로 용접 부착하고, 상기 I빔 세그멘트 연결접합용 보조플랜지 상하면에 연결 접합용 연결강판을 고장력볼트로 고정 접합함을 특징으로 한다.In order to achieve the above object, an I beam segment temporary bridge connecting method having increased joint stiffness according to the present invention is a temporary bridge for connecting and installing I beam segments, and the left and right upper abdomen in the vicinity of a connection joint of the I beam segment The steel plate or the square steel plate on the surface by welding attached to the auxiliary flange for the connection, characterized in that the fixed connection of the connection steel plate for connection bonding to the upper and lower surfaces of the auxiliary flange for the I-beam segment connection junction fixed with high-strength bolt.

이상에서 설명한 바와 같이, 본 발명에 따른 연결부 강성이 증대된 I빔 세그멘트 가설교량 연결방법은 I빔 세그멘트 가설교량의 I빔 세그멘트 연결 접합부 부근 복부 상단에 일자형 강판 또는 각형 강판을 연결접합용 보조 플랜지로 용접 부착하여 I빔 세그멘트 연결시 상부플랜지를 대신해서 연결강판과 고장력볼트로 연결 접합하면, 복공판의 돌출 우려 없이 수평면을 유지할 수 있고, 설치도 용이하고 해체시에는 I빔 세그멘트의 모재 손상이 전혀 없어 재활용 비율을 높이고 연결접합 강성을 하부플랜지와 동일하게 할 수 있어 I빔 세그멘트 연결부 개소를 증대할 수 있기 때문에 응력도에 기준으로 한 연결 접합부를 고려하지 않아도 되므로 장경간 가설교량이 가능한 장점이 있다.As described above, the method of connecting the I-beam segment temporary bridge with increased joint stiffness according to the present invention includes a straight steel plate or a square steel plate as an auxiliary flange for connection joint at the upper part of the abdomen near the I-beam segment connection joint of the I-beam segment temporary bridge. When I-beam segment is connected by welding, it is possible to maintain the horizontal plane without the risk of protruding the perforated plate by connecting the connecting steel plate and the high-tension bolt instead of the upper flange, and it is easy to install and there is no damage to the base material of the I-beam segment during disassembly. It is possible to increase the recycling rate and to make the connection joint stiffness the same as the lower flange, thereby increasing the I-beam segment connection point, so that it is not necessary to consider the connection joint based on the stress level, so there is an advantage in that it is possible to construct a long span bridge.
