Description
본 발명은 교량의 콘크리트 상판에 있어서 단위 구간 사이의 간극에 누수가 발생하지 않고 이물질이 개재되지 않으며 기온에 따른 콘크리트 상판의 신축에 적응 할 수 있도록 한 교량의 신축연결장치에 관한 것이다.The present invention relates to a bridge connecting and extending the bridge so that no leakage occurs in the gap between the unit section in the concrete deck of the bridge, no foreign matter is interposed and can adapt to the expansion and contraction of the concrete deck according to the temperature.
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 발명은 이러한 점에 착안하여 설치 상태가 견고하고 설치 및 교체가 용이하며 도로 상판의 신축에 적절히 대응할 수 있는 교량의 신축연결장치를 제공하는데 목적을 두고 있다. 이러한 목적을 달성하기 위하여 일반도로와 달리 교량의 특수성을 고려하고 설치가 손쉬우며 배수가 용이하고 간극이 효과적으로 밀봉될 수 있는 구조가 바람직하다.SUMMARY OF THE INVENTION The present invention has been made in view of this point, and an object of the present invention is to provide a flexible connecting device for bridges that can be installed in a solid installation state, easy to install and replace, and appropriately cope with the expansion and contraction of a 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 발명은 기존 교량의 콘크리트층 및 아스팔트층의 일부를 절삭한 후 콘크리트층의 철근프레임에 장착한 후 아스콘으로 마감하여 매립하는 구조로 되어있다.The present invention has a structure of cutting a portion of the concrete layer and asphalt layer of the existing bridge and then mounted to the reinforcing frame of the concrete layer and then finished with ascon and landfill.
본 발명의 교량의 신축연결장치는 고정레일(1)과 고정금구(5), 그리고 신축연결재(10)로 구성된다. 다시 말해, 전면에는 결합홈(4)이, 배면에는 플렌지(3)와 고정홈(2)이 형성된 고정 레일(1)과, 고정홈(2)에 삽착되며 플렌지(3)의 상부 하단 즉 고정레일(1)의 배면에 있는 나사홈(1a)에, 단부에 나사산(7a)을 구비하고 있는 금구고정볼트(7)로 고정되고 배면에 볼트머리를 가진 한 쌍의 브라켓(6)이 결합된 고정금구(5)와 결합홈(4)에 삽착편(9)과 함께 끼워 지며 좌우에 결합편(11)과 파지편(12)이 지성된 V자형 신축연결재(10)가 유기적으로 결합된 구조이다. 즉, 도 3에 도시된 바와 같이 고정금구(5)에 연결된 브라켓(6)이 철근(17)과 용접되어 아스콘층(16)에 매립되며 상기 고정금구(5)는 그 중심을 관통하는 금구고정볼트(7)에 의하여 고정레일(1)의 하단부에 나사결합된다. 이와 같은 구조로 형성됨으로써 본 발명의 신축연결장치는 양 교량의 아스콘층(16)에 브라켓(6)이 고정되어 있는 고정금구(5)가 매립되고 이 고정금구(5)가 고정금구볼트(7)에 의해 고정레일(1)에 나사결착되므로 양 교량의 간극을 신축자재로이 연결하는 신축연결재(10)가 상기 고정레일(1)의 결합홈(4)에 삽착편(9)과 함께 결합볼트(8)에 압착되어 결합되어서 고정레일(1)과의 사이에 공간없이 확고하게 밀착고정되어 빗물 등이 스며들지 않고 제 기능을 확실히 발휘할 수 있다.The stretchable connecting device of the bridge of the present invention is composed of a fixed rail (1), a fixed bracket (5), and a flexible connecting member (10). In other words, the coupling groove (4) on the front, 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 the upper lower end of the flange (3) A pair of brackets 6 having a bolt head on the rear side are fixed to the screw groove 1a on the rear side of the rail 1 by a bracket fixing bolt 7 having a screw thread 7a at the end thereof. Fitted together with the insertion piece (9) in the fixing bracket (5) and the coupling groove (4), the structure of the organically coupled V-shaped elastic connector (10) consisting of the coupling piece 11 and the gripping piece (12) on the left and right to be. That is, as shown in FIG. 3, the bracket 6 connected to the fixing bracket 5 is welded with the rebar 17 to be embedded in the ascon layer 16, and the fixing bracket 5 penetrates the center thereof. It is screwed to the lower end of the fixing rail (1) by the bolt (7). By forming in such a structure, in the flexible connecting device of the present invention, the fixing bracket 5 in which the bracket 6 is fixed to the ascon layer 16 of both bridges is embedded and the fixing bracket 5 is fixed to the fixing bolt 7 Since the screw is fastened to the fixed rail (1) by means of expansion and contraction material (10) for connecting the gap between the two bridges with elastic materials, the coupling bolt (9) with the insertion piece (9) in the coupling groove (4) of the fixed rail (1) (8) is pressed and combined to be firmly fixed without space between the fixed rail (1), it is possible to reliably exert the function without the rain water.
교량의 구조에 따라 도 4와 같이 고정금구(5)의 브라켓(6)을 하나로 하여 말단을 하향 절곡한 구조를 취할 수도 있다. 신축연결재(10)는 상기 도 3에서와 동일하게 고정홈(2)에 삽착편(9)과 함께 삽착되어 고정레일(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.Depending on the structure of the bridge, as shown in FIG. The flexible connecting member 10 is inserted into the fixing groove 2 together with the insertion piece 9 in the same manner as in FIG. 3 and fastened to the coupling bolt 8 on the upper surface of the fixing rail 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 발명은 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).
