Description
본 발명은 교량용 신축이음장치 및 그 보수공법에 관한 것이다. 보다 구체적으로, 본 발명의 신축이음장치와 상기 신축이음장치 양 옆에 타설되어 신축이음장치를 교량 상판에 고정시키는 무수축콘크리트가 신축이음장치를 구성하고 있는 내부지지강재의 상부키로 분리되어 있어 상기 무수축콘크리트를 파쇄하지 않고 신축이음장치를 보수할 수 있는 교량용 신축이음장치 및 그 보수공법에 관한 것이다.The present invention relates to an expansion joint device for bridges and a repair method thereof. More specifically, the non-concrete concrete, which is placed on both sides of the expansion joint device and the expansion joint device of the present invention to fix the expansion joint device to the bridge top plate, is separated by an upper key of the inner supporting steel constituting the expansion joint device. The present invention relates to a bridge expansion joint device capable of repairing expansion joint devices without shredding non-concrete concrete, and a repair method thereof.
교량구조물은 온도변화와 하중에 따라 팽창하고 수축되므로 일정길이 이상으로 설치되는 교량의 상부구조물은 팽창·수축으로 인한 교량의 상부구조물의 손상을 막기 위해 적정한 간격을 두고 설치된다. 상기 교량의 상부구조물의 간격을 이어주는 장치가 교량용 신축이음장치이며 통상 교면에 일치하는 표면지지강재(11)와 일체화된 내부지지강재(12), 교량의 표면수 및 이물질이 신축이음장치를 통하여 교량의 하부로 흘러가지 못하도록 상기 내부지지강재 사이에 열융착 또는 접착재로설치되는 신축고무(13) 및 신축이음장치를 교량 상부구조물에 고정시키기 위해 신축이음장치 양 옆에 타설되는 무수축콘크리트(14)로 구성된다. 상기 종래의 신축이음장치는 도1A에 도시된 바와 같이 내부지지강재와 신축고무(13)가 교통하중, 교량의 신축 또는 이물질에 의해 상기 내부지지강재 및 무수축콘크리트보다 조기에 손상 탈락되어 우수 시에 신축이음장치에 유입된 표면수가 교량의 하부로 흘러 들어가 교량의 거더(16), 교좌장치(17) 및 교각(18)에까지 해로운 영향을 주게되는 문제점이 있다. 따라서 신축고무가 손상된 신축이음장치를 보수하기 위해 종래에는 신축이음장치 양 옆에 타설된 무수축콘크리트(14) 및 내부철근(15)을 모두 파쇄·절단한 뒤 신축이음장치 전체를 교체하기 때문에 교량용 신축이음장치의 보수작업공기가 길어지고 작업공정이 복잡하며 비경제적이라는 문제점이 있다. 또한 도1B에 도시된 바와 같이 내부지지강재(19)와 신축고무(13)가 서로 분리되어 있는 신축이음장치인 경우 신축이음장치를 보수하기 위해 양 옆에 설치되어 있는 무수축콘크리트를 파쇄하지 않아도 된다는 장점은 있으나 내부지지강재 사이에 설치되는 신축고무(13)를 신축이음장치의 옆에서 밀어 넣으면서 설치하기 때문에 교량 폭에 따라 보수작업에 어려움이 많다는 문제점이 있다.As the bridge structure expands and contracts according to temperature change and load, the upper structure of the bridge installed over a certain length is installed at appropriate intervals to prevent damage to the upper structure of the bridge due to expansion and contraction. The device that bridges the gap of the upper structure of the bridge is the expansion joint device for bridges, and the inner support steel 12, which is integrated with the surface support steel 11, which is generally matched to the bridge, the number of surfaces of the bridge and foreign matter through the expansion joint device Non-concrete concrete 14 which is placed on both sides of the expansion joint to fix the expansion rubber 13 and the expansion joint to be installed to the upper structure of the bridge by heat-sealing or adhesive material between the inner support steel to prevent flow to the lower portion of the bridge It is composed of In the conventional expansion joint device, as shown in FIG. 1A, the inner support steel and the elastic rubber 13 are damaged and dropped earlier than the inner support steel and the non-concrete concrete due to traffic load, expansion or contraction of a bridge, and the like. There is a problem in that the surface water introduced into the expansion joint device flows into the lower portion of the bridge and adversely affects the girder 16, the bridge device 17, and the bridge 18 of the bridge. Therefore, in order to repair the expansion joints in which the expansion rubber is damaged, conventionally, the expansion joints are replaced because all the expansion joints are replaced after crushing and cutting all the non-concrete concretes 14 and the inner reinforcing bars 15 placed on both sides of the expansion joints. There is a problem that the maintenance work air of the expansion joint device for long, the work process is complicated and uneconomical. In addition, as shown in FIG. 1B, in the case of the expansion joint device in which the internal support steel 19 and the expansion rubber 13 are separated from each other, the non-concrete concrete installed on both sides of the expansion joint device does not have to be broken. There is an advantage, but there is a problem in that it is difficult to repair work depending on the width of the bridge because it is installed while pushing the expansion rubber 13 installed between the inner support steel in the expansion joint.
본 발명의 목적은 신축이음장치와 상기 신축이음장치 양 옆에 타설되는 무수축콘크리트를 본 발명의 신축이음장치의 내부지지강재에 형성된 외주면 키 로 분리하여 무수축콘크리트를 파쇄하지 않고 신축이음장치를 보수할 수 있는 교량용 신축이음장치 및 그 보수공법을 제공하는 것이다.An object of the present invention is to separate the expansion joint device and the non-concrete concrete placed on both sides of the expansion joint device by the outer peripheral surface key formed on the inner support steel of the expansion joint device of the present invention to expand the expansion joint device without breaking the non-concrete concrete It is to provide a renovable expansion joint device for bridge and its repair method.
