Description
본 고안은 교량의 콘크리트 상판에 있어서 단위 구간 사이의 간극에 있어서,단위 구간 사이의 간극에 누수가 발생하지 않고 이물질이 개재되지 않으며 기온에 따른 콘크리트 상판의 신축에 적응 할 수 있도록 한 교량의 신축연결부에 관한 것이다.The present invention is the expansion joint of the bridge that can be adapted to the expansion of the concrete deck according to the temperature in the gap between the unit sections in the concrete deck of the bridge, no leakage occurs in the gap between the unit sections, foreign matter intervening It is about.
알려진 바와 같이 콘크리트는 기온에 따라 신장 및 수축이 크며 이에 대응하기 위하여 단위 구간 사이에 최대 5cm, 통상 2-3cm의 신축간격을 두고 있다. 그러나 단위 구간 사이의 간극에 빗물이 스며들거나 토사 등 이물질이 개재되면 단위 콘크리트 구간의 신축작용에 무리가 따른다. 특히, 겨울철에는 도로에 염화마그네슘을 살포하므로 간극을 통하여 유입되는 눈 녹은 물이 교량을 부식 시킬 뿐만 아니라 교각에 흘러내려 외관을 더럽히게 된다.As is known, concrete has a large elongation and contraction according to temperature, and has a stretching interval of up to 5 cm, usually 2-3 cm, between unit sections. However, when rainwater enters the gap between the unit sections or foreign matter such as earth and sand intervenes, it is difficult to stretch the unit concrete section. Particularly, in winter, magnesium chloride is sprayed on the road, and the snow melted inflow through the gap not only corrodes the bridge, but also flows into the bridge to pollute the exterior.
본 고안은 이러한 점에 착안하여 설치 상태가 견고하고 설치 및 교체가 용이하며 도로 상판의 신축에 적절히 대응할 수 있는 교량의 신축연결부를 제공하는데 목적이 있다. 이러한 목적을 달성하기 위하여 일반도로와 달리 교량의 특수성을 고려하고 설치가 손쉬우며 배수가 용이하고 간극이 효과적으로 밀봉될 수 있는 구조가 바람직하다.The present invention has been made in view of this point, and the purpose of the installation is solid, easy to install and replace, and to provide a flexible connection of the bridge that can respond appropriately to the construction of the road deck. In order to achieve this purpose, unlike the general road, it is preferable to consider the specificity of the bridge, easy installation, easy drainage, and a structure that can effectively seal the gap.

본 고안은 기존 교량의 콘크리트층 및 아스팔트층의 일부를 절삭한 후 콘크리트층의 철근프레임에 장착한 후 아스콘으로 마감하여 매립하는 구조로 되어있다.The present invention has a structure in which a portion of the concrete layer and asphalt layer of the existing bridge is cut and then mounted on the reinforcing frame of the concrete layer and then finished with ascon and landfilled.
본 고안은 고정레일(1)과 고정금구(5), 신축연결재(10)로 구성된다. 전면에는 결합홈(4)이, 배면에는 플렌지(3)와 고정홈(2)이 형성된 고정 레일(1)과, 고정홈(2)에 삽착되며 플렌지(3)에 금구고정볼트(7)로 고정되고 배면에 볼트머리를 가진 한 쌍의 브라켓(6)이 결합된 고정금구(5), 결합홈(4)에 삽착편(9)과 함께 끼워 지며 좌우에 결합편(11)과 파지편(12)이 형성된 V자형 신축연결재(10)가 유기적으로 결합된 구조이다.The present invention is composed of a fixed rail (1) and a fixed bracket (5), stretchable connecting member (10). The coupling groove (4) on the front, and the fixed rail (1) formed with the flange (3) and the fixing groove (2) on the back, and is inserted into the fixing groove (2) and fastening bolts (7) to the flange (3) A fixed bracket (5), which is fixed and has a pair of brackets (6) having a bolt head on the back, is fitted together with the insertion piece (9) in the coupling groove (4), and the coupling piece (11) and the grip piece (left and right) 12) is a structure in which the V-shaped stretching connector 10 is organically bonded.
교량의 구조에 따라 도 4와 같이 고정금구(5)의 브라켓(6)을 하나로 하여 말단을 하향 절곡한 구조를 취할 수 있다. 신축연결재(10)는 고정홈(2)에 삽착편(9)과 함께 삽착되어 고정제일(1)의 상면에서 결합볼트(8)로 체결된다. 브라켓(6)의 볼트머리는 철근프레임(14)에 용접된 가로철근(17)에 파지되며 조립이 끝난 후 아스콘층(16)으로 마감처리된다. 도면 중 미설명부호 13은 콘크리트층, 14는 철근프레임, 15는 아스팔트층, 16은 아스콘층, 17은 가로철근이다.According to the structure of the bridge, as shown in FIG. 4, the bracket 6 of the fixing bracket 5 can be taken as a structure in which the end is bent downward. The elastic connector 10 is inserted into the fixing groove 2 together with the insertion piece 9 and fastened to the coupling bolt 8 on the upper surface of the fixing first 1. The bolt head of the bracket 6 is gripped by the rebar 17 welded to the reinforcing frame 14 and finished with the ascon layer 16 after the assembly is completed. In the drawings, reference numeral 13 denotes a concrete layer, 14 a reinforcement frame, 15 an asphalt layer, 16 an ascon layer, and 17 a horizontal rebar.
본 고안은 교량의 철근 프레임의 구조를 이용하여 고정되며 브라켓에 의하여 고정금구 및 고정레일이 견고히 결합되고 V자형 신축연결재(10)가 손쉽게 결합 및 해체 될 수 있는 구조를 갖는다. 신축연결부재(10)의 V자형 형태에 의하여 기후변화에 따른 신축이 원활하고 외관이 깔끔히 처리된다.The present invention is fixed using the structure of the reinforcing frame of the bridge, and the fixing bracket and the fixed rail is firmly coupled by the bracket and has a structure that can be easily coupled and disassembled V-shaped elastic connector (10). Due to the V-shaped shape of the elastic connection member 10, the expansion and contraction according to the climate change is smooth and the appearance is neatly processed.
