EXPANSION JOINT AND CONSTRUCTION METHOD THEREOF
According to the present invention, an expansion joint structure includes: a left foundation part (110) and a right foundation part (120) which are spaced apart from each other to form a foundation part expansion part (130); a left concrete slab (210) and a right concrete slab (220) formed in upper parts of the left foundation part (110) and the right foundation part (120), respectively, to form a slab expansion part (230) which is longer than the foundation part expansion part (130); a high-softness concrete composition (300) filling the slab expansion part (230); a pair of fixing anchors (400) having a lower part buried in each of the left foundation part (110) and the right foundation part (120), and having an upper part buried in the high-softness concrete composition (300); a sliding pad (500) installed in a section between a pair of the fixing anchors (400) as well as installed in a structure, in which the pad is placed in common on an upper side of a right edge part of the left foundation part (110) and an upper side of a left edge part of the right foundation part (120), in order to prevent the high-softness concrete composition (300) from flowing down to the foundation part expansion part (130), and to form the high-softness concrete composition (300) and the left foundation part (110) and the high-softness concrete composition (300) and the right foundation part (120) in a non-junction structure; and a pavement part (600) placed in upper parts of the left concrete slab (210), the right concrete slab (220) and the high-softness concrete composition (300). Meanwhile, lower protruding parts (510) protruding downward are formed on a lower side of the sliding pad (500) at intervals from each other in a lateral direction.
본 발명의 신축이음구조물은 기초부신축부(130)가 형성되도록 상호 이격된 좌측기초부(110) 및 우측기초부(120); 기초부신축부(130)보다 긴 슬래브신축부(230)가 형성되도록 좌측기초부(110)와 우측기초부(120)의 상부에 각각 형성된 좌측콘크리트 슬래브(210) 및 우측콘크리트 슬래브(220); 슬래브신축부(230)에 충전되는 고연성 콘크리트 조성물(300); 하부는 좌측기초부(110) 및 우측기초부(120)에 각각 매립되고, 상부는 고연성 콘크리트 조성물(300)에 매립되도록 설치되는 한 쌍의 고정앵커(400); 고연성 콘크리트 조성물(300)이 기초부신축부(130)로 흘러내리는 것을 방지하고, 고연성 콘크리트 조성물(300)과 좌측기초부(110), 고연성 콘크리트 조성물(300)과 우측기초부(120)를 비접합 구조로 형성하기 위해, 한 쌍의 고정앵커(400)의 사이 구간에 설치됨과 아울러, 좌측기초부(110)의 우측 가장자리부 상면과 우측기초부(120)의 좌측 가장자리부 상면에 공통으로 올려지는 구조로 설치되는 슬라이딩패드(500); 좌측콘크리트 슬래브(210), 우측콘크리트 슬래브(220), 고연성 콘크리트 조성물(300)의 상부에 타설된 포장부(600);를 포함하되, 슬라이딩패드(500)의 하면에는 측방향을 따라 상호 간격을 두고, 하측으로 돌출된 하면돌부(510)가 형성된다.
