본 발명은 신축이음장치의 고무방수부재에 관한 것으로서, 보다 상세하게는 고가도로나 교량의 연결부에 장착되는 고무방수부재의 장착구조를 개선하여 설치 및 분해 작업이 용이하게 이루어질 수 있도록 하는 신축이음장치의 고무방수부재에 관한 것이다.The present invention relates to a rubber waterproof member of an expansion joint device, and more particularly, to an expansion joint device for improving the mounting structure of a rubber waterproof member mounted on a connection part of an overpass or a bridge so that installation and disassembly work can be easily performed. It relates to a rubber waterproof member.

일반적으로 다수의 교각을 가지는 비교적 길이가 긴 교량에는 온도 변화에 따른 교량의 팽창 및 수축에 대응하기 위하여 교량의 상판을 교량의 길이 방향으로 여러 개의 부분으로 나누고, 각 분할된 상판 슬래브 사이에는 신축 이음장치를 설치하게 된다. In general, in a relatively long bridge with a large number of bridges, the top plate of the bridge is divided into several parts in the longitudinal direction of the bridge to cope with the expansion and contraction of the bridge according to the temperature change, and the expansion joint between each divided slab slabs. You will install the device.

도 1 및 도 2에 도시된 바와 같이 종래의 교량용 신축이음장치는 분할된 교량 상판부의 대면하는 단부에 상호 맞물림 결합되도록 각각 설치되어, 온도 변화에 따라 신축 작용하는 상부 덮개판(101a)(101b)과, 그 상부 덮개판(101a)(101b)을 후타 콘크리트(105)에 결속하여 고정시키는 앙카 볼트(102)와, 앙카 볼트(102)와 후타 콘크리트(105)의 결속력 증대 및 후타 콘크리트(105)의 강도 보강을 위한 보강 철근(103)과, 상기 양측 후타 콘크리트(105)에 그 단부가 각각 고정되도록 설치된 우수 및 이물질 수거용 고무방수부재(104)로 구성되어 있다. 참조번호 106은 교량의 상판부 내부의 슬래브 철근을 나타낸다.As shown in FIGS. 1 and 2, the conventional expansion joint apparatus for bridges is respectively installed to be engaged with each other at the opposite ends of the divided bridge upper plate portions, and the upper cover plates 101a and 101b which expand and contract according to temperature changes. ), An anchor bolt 102 for binding and fixing the upper cover plates 101a and 101b to the futa concrete 105, an increase in the binding force between the anchor bolt 102 and the futa concrete 105, and the futa concrete 105 Reinforcement reinforcement (103) for reinforcing the strength of the) and the both sides of the futa concrete 105 is composed of a rubber waterproof member 104 for rainwater and foreign matter collection is installed so that the end is fixed respectively. Reference numeral 106 denotes slab reinforcing bars inside the upper plate of the bridge.

상기와 같은 종래 구조의 신축이음장치는 온도변화 등의 요임에 의해 교량의 길이가 변화되어 후타 콘크리트(105) 간의 간격이 변경되면 그 길이변화만큼 상부 덮개판(101a)(101b)이 신축량만큼 거동되어 그 길이를 보정하게 되는 것이다.In the conventional expansion joint device as described above, when the length of the bridge is changed due to the temperature change and the like, and the interval between the futa concrete 105 is changed, the upper cover plates 101a and 101b behave as much as the length change. The length is corrected.

또한, 각각의 후타 콘크리트(105) 사이에 볼트로 고정된 고무방수부재(104)는 후타 콘크리트(105) 간격의 신축량에 따라 굽혀지면서 상부 덮개판(101a)(101b)의 틈새로 유입되는 빗물이나 오염물질이 교량 내부로 스며들어 부식되어가 오염되는 것을 방지한다.In addition, the rubber waterproof member 104 bolted between each of the futa concrete 105 is bent in accordance with the amount of expansion and contraction of the futa concrete 105, rainwater flowing into the gap of the upper cover plate (101a, 101b) or Contaminants penetrate into the bridge and corrode to prevent contamination.

그러나, 상기와 같이 구성된 종래 구조의 고무방수부재(104)는 후타 콘크리 트(105)에 볼트로 체결되는 구조로 형성되어 볼트로 공구를 체결하는 작업공간이 협소하므로 설치 및 분해 작업시 작업에 어려움이 있다. However, the rubber waterproof member 104 of the conventional structure configured as described above is formed in a structure that is fastened to the futa concrete 105 with a bolt, so that the work space for fastening the tool with the bolt is narrow, so it is difficult to work during installation and disassembly work. There is this.
