EXPANSION JOINT APPARATUS HAVING HIGH ELASTIC DUST INTRUSION PROTECTION UNIT
Disclosed is an extension joint device having a high elastic foreign material intrusion preventing unit. The extension joint device having a high elastic foreign material intrusion preventing unit according to an embodiment of the present invention comprises: a pair of finger joint plates disposed to face each other at the top of a bridge, and having a plurality of finger threads and finger grooves respectively formed continuously and repeatedly on surfaces facing each other, wherein finger threads facing each other are arranged in a staggered bolt shape; and a foreign material intrusion preventing unit coupled with each of the finger grooves, having both side surfaces formed in projection shapes closely placed on the finger grooves, maintained in a state of being closely placed on the bottom surfaces of the finger threads while the finger threads slide in the finger grooves during expansion and shrinkage of the bridge, and downwardly bent in accordance with a movement of the finger threads so as to prevent foreign materials from being fed to the bottom thereof. The foreign material intrusion preventing unit is made of a polyurethane resin, and additionally comprises 1-5 parts by weight of a cardanol-based epoxy resin with respect to 100 parts by weight of polyurethane resin.
고탄성 이물질 유입 방지유닛을 구비한 신축이음장치가 개시된다. 본 발명의 일 실시예에 따른 고탄성 이물질 유입 방지유닛을 구비한 신축이음장치는 교량의 상부에 상호 대향되게 마련되며, 상호 대향되는 일면에 각각 핑거산과 핑거홈이 연속하여 복수 개 반복 형성되며, 상호 대향되는 핑거산은 상호 엇갈려 있는 빗장형태로 배열되는 한 쌍의 핑거조인트판; 및 핑거홈에 각각 결합되고 양측면이 핑거홈에 밀착된 돌기형상을 가지며, 교량의 팽창 및 수축 시에 핑거산이 핑거홈 내에서 슬라이딩 이동하는 동안 핑거산의 하면에 밀착된 상태를 유지하면서 핑거산의 이동에 따라 하향 절곡되어 이물질이 하부로 유입되는 것을 방지하는 이물질 유입 방지유닛을 포함하며, 이물질 유입 방지유닛은 재질이 폴리우레탄 수지로서 폴리우레탄 수지 100 중량부를 기준으로 카다놀계 에폭시 수지를 1-5 중량부 추가로 포함한다.
