Description

다주형으로 구성된 육교{an overpass}Overpass consisting of multiple columns {an overpass}

본 발명은 다주형(병열주행)으로 구성된 육교에 관한 것으로, 상세하게는 육교을 구성함에서 있어, 복수개로 된 주형를 결합하여 하나의 주형으로 구성하고, 그 상측으로 상자형교를 결합하여 육교로 사용할 수 있도록 한 것이다.The present invention relates to an overpass composed of multi-templates (parallel running), and in detail, the overpass is configured, and a plurality of molds are combined to form a single mold, and a box-type bridge can be combined to be used as an overpass. It would be.

육교의 주형은 육교계획을 하거나 육교를 채용하는 경우 여러가지 형식이 존재할 수 있으나, 시공이 편리하고 경제적인 주형을 이용한 형식을 보편적으로 채용하고 있다.There are various forms of overpass molds when overpass plans or overpasses are employed, but they are commonly adopted using convenient and economical molds.

상기의 주형을 이용한 강교형식으로는 양측으로 마주하는 한개의 주형 상측에 개단면판 형교(플레이트 거더교 또는 I형교)와 폐단면판 형교(박스 거더교 또는 상자형교)로 된 형교를 결합하여 구성되며, 개단면교에 비하여 폐단면교가 그 특성상 비틈강성이 크며, 개단면교에 필요한 여러가지 보강부재(수평, 수직 브레이싱 등)가 생략되어질 수 있고, 이에 따른 시공의 편이성 및 시공오차를 최소화 할 수 있어, 폐다면교가 많이 활용되고 있다.The steel bridge type using the above-mentioned mold is composed of a single cross-section bridge bridge (plate girder bridge or I-beam bridge) and a closed cross-section bridge bridge (box girder bridge or box bridge bridge) on the upper side of one mold facing each side. Compared to the cross-section bridge, the closed cross-section bridge has a large gap stiffness, and various reinforcing members (horizontal, vertical bracing, etc.) required for the open cross-section bridge can be omitted, thereby minimizing construction convenience and construction errors. Multifaceted bridges are used a lot.

그러나 상기의 1개의 주형으로 이루어진 단주형 육교는, 시공하고자 하는 육교의 교폭이 클 경우, 단주형 상자형 육교는 강주형의 단면이 크게 되어, 한개의 주형으로는 육교의 자체하중이나 편재되는 하중을 감당하기 어렵워, 설치된 육교가 흔들거리나거 뒤틀림이 심하여, 안전상의 문제점으로 인해 잦은 보수와 재 설치로 많은 경제적 손실을 발생 시키며, 육교를 시공하거나 보수하는 작업시간이 많이 소요되어, 많은 설치비로 인하여, 경쟁력을 가지지 못하는 문제점이 있었다.However, in the case of the above-mentioned single column type overpass consisting of one mold, if the bridge width of the overpass is intended to be large, the single column type box overpass has a large cross section of the steel casting type, and one mold carries the self-load or ubiquitous load of the overpass. Because it is difficult to handle, the installed overpass is shaken or warped, causing frequent economic loss due to frequent maintenance and re-installation due to safety problems, and it takes a lot of work time to construct or repair overpass. However, there was a problem of not being competitive.

본 발명은 상기의 문제점을 감안하여, 구별되어 있는 2개의 주형을 지면에 설치하여 상측에서 거더 받침대와 거더로 결합하고 상판을 형성하여, 육교를 구성하므로, 설치되는 육교의 유효 플랜지 면적은 넓히고 육교에 설치되는 플랜지의 두께를 줄일 수 있도록 발명된 것으로, 첨부된 도면에 의해 상세하게 설명하면 다음과 같다.In view of the above problems, the present invention installs two distinct molds on the ground, combines the girder pedestal and the girder from the upper side, forms a top plate, and constitutes an overpass, so that the effective flange area of the overpass installed is wide and overpass Invented to reduce the thickness of the flange to be installed in, described in detail by the accompanying drawings as follows.

분리되어 있는 2개의 주형(1)(1')(2)(2')을 양측으로 형성하여 중간에 만곡형 거더 받침대(3)(3')를 형성하여, 거더 받침대(3)(3') 상측 상측으로 거더(4)(4')를 각각 형성하여 다주영(5)으로 구성하고, 형성된 거더(4)(4') 내측으로 다수개의 연결 크로스 빔(6)..로 고정하고, 거더(4)(4') 상측에 상판(7)을 결합하여서 된 것이다.Two separate molds (1) (1 ') (2) (2') are formed on both sides to form a curved girder pedestal (3) (3 ') in the middle to form a girder pedestal (3) (3'). Girder (4) (4 ') formed on the upper side to form a multi-jump (5), and fixed with a plurality of connecting cross beams (6) .. inside the formed girder (4) (4'), The upper plate 7 is attached to the girder 4, 4 'upper side.

이와 같이 된 본 발명은 설치는 지면으로 부터 상측의 상판(7)에 위치하는 상자형교를 지지하는 주형(1)(1')과 마주하는 주형(2)(2')을 동일한 형태로 일정간격 이격하여 설치하고, 주형(1)(1')(2)(2')의 상단에, 연결 크로스 빔(6)..이 대수개 형성된 거더(4)(4')가 위치할 수 있도록 거더 받치대(3)(3')을 주형(1)(1')과 마주하는 주형(2)(2')를 이용하여 설치하므로, 부분리되어 있는 주형(1)(1')(2)(2')을 결합하여 주는 것이다.In the present invention as described above, the mold is spaced apart from the ground by the mold (2) (2 ') facing the mold (1) (1') for supporting the box-shaped bridge located on the upper plate (7) of the upper side in the same form. On the top of the molds (1) (1 ') (2) (2'), the girders (4) (4 ') having a large number of connecting cross beams (6). Since the support stand (3) (3 ') is installed using the mold (2) (2') facing the mold (1) (1 '), the mold (1) (1') (2) is partly separated. (2 ') is combined.

상기와 같이 분리되어 있는 주형(1)(1')(2)(2')을 결합하여, 하나의 다주형(복수주형)(5)으로서, 상부에 위치할 거더(4)(4')를 받치는 기능을 수행할 수 있도록 한 상태에서, 그 상측으로 위치한 거더(4)(4')위에 상판(7)과 상자형교를 위치시켜, 계단(8)과 난간(9)를 설치하여, 육교(10)로 사용하는 것이다.The girder (4) (4 ') to be located at the top as a single multi-mould (plural mold) 5 by combining the mold (1) (1') 2 (2 ') separated as described above. The upper plate 7 and the box-shaped bridge are placed on the girders 4 and 4 'positioned upward, and the stairs 8 and the railings 9 are installed, and the overpass is provided. (10) to use.

이러한 본 발명은 지면을 지지하는 주형(1)(1')(2)(2')이 2개로 되어 있어, 하나의 주형(1)(1')(2)(2')이 지면에 접하는 면적보다 넓게 지면에 접하므로, 상자형교의 하중과 상자형교(7) 상측으로 가해지는 하중을 해소할 수 있으며, 상자형교에서 가해지는 하중을 단독주형이 받지 않고, 이격되어 있는 주형(1)(1')과 마주하는 주형(2)(2')가 분배하여 감당할 수 있도록 한 것이다.In the present invention, two molds (1) (1 ') (2) (2') supporting the ground are provided so that one mold (1) (1 ') (2) (2') is in contact with the ground. Since the surface is in contact with the ground wider than the area, the load of the box-shaped bridge and the load applied to the upper side of the box-shaped bridge (7) can be eliminated, and the mold (1) spaced apart without receiving the load applied from the box-shaped bridge ( 1 ') and the mold (2) (2') facing the distribution to be able to afford.

그러므로 본 발명에서 사용되는 거더 받침대(3)(3')의 경우에는 받침대 중앙으로 갈수록 폭을 좁게 설계할 수 있어, 육교(10)를 설계함에 미관이 수려한 육교(10)를 설치할 수 있는 것이다.Therefore, in the case of the girder pedestal (3) (3 ') used in the present invention can be designed to narrow the width toward the center of the pedestal, it is possible to install the overpass 10 beautiful in designing the overpass 10.

또한 거더(4)(4')에 형성된 연결 크로스 빔(6)..이 수평으로 위치한 거더(4)(4')를 수직으로 잡아 주므로, 거더(4)(4')가 받는 비틈하중이 분리되어 있는 각 주형의 전단력으로 분산되기 때문에, 비틈에 의한 플랜지에 작용하는 전단응력과 휨(Warpping)에 의한 막응력(membranes stress)을 분산되는 것이다.In addition, since the connecting cross beams 6 formed on the girders 4 and 4 'hold the horizontally positioned girders 4 and 4' vertically, the gap loads received by the girders 4 and 4 ' Since the shear force of each mold is separated, the shear stress acting on the flange due to the gap and the membrane stress due to warpping are dispersed.

또한 본 발명은 육교(10)가 설치되는 지면의 평탄이 일정하지 않은 상태의 경우에는, 설치되는 2개의 주형(1)(11)과 주형(2)(2')을 지면의 고저에 따라 길이를 달리 구성하여 시공할 수 있으며, 본 발명의 육교(10)의 시공은 주형(1)(1')(2)(2'), 만곡형 거더 받침대(3)(3'), 거더(4)(4'), 상판(7)의 결합은 볼트결합이나, 용접 접합을 시공자가 선택하여 할 수 있는 것이다.In addition, in the present invention, when the flatness of the ground on which the overpass 10 is installed is not constant, the lengths of the two molds (1) 11 and the molds (2) (2 ') to be installed are along the height of the ground. The construction can be constructed differently, the construction of the overpass 10 of the present invention is a mold (1) (1 ') (2) (2'), curved girder pedestal (3) (3 '), girder (4) 4 ') and the upper plate 7 can be bolted or welded together by the installer.

상기에서 상세하게 설명한 바와 같이, 다주형(5)으로 구성된 육교(10)는, 한개의 주형으로 구성되는 육교에 비하여 비틈강성이 크고, 육교(10) 상부에서 발생한 비틈이 거더(4)(4')와 연결 크로스 빔(6)..에 의해하여 각 주형(1)(1')(2)(2')의 전단력으로 분산되기 때문에, 비틈에 의한 플랜지에 작용하는 전단응력과 휨에 의한 막응력을 분산시켜 주는 효과가 있으며, 육교의 폭이 길어 질 수록 필연적으로 다주형교향으로 변경하여 계획되어야 안전성을 보장받고 시공도 편리며, 또한 단주형 육교에 비하여 다주형 육교의 유효 플랜지 면적이 넓으므로 프랜지의 두께를 줄일 수 있는 효과와, 거더 받침대(3)(3')의 형태가 중앙으로 갈수록 폭이 좁하지는 형태를 취할 수 있어, 거더 받침대(3)(3')의 부재량을 줄임과 동시에, 외관이 미려한 육교(10)를 시공하는 효과가 있다.As described in detail above, the overpass 10 composed of the multi-casting mold 5 has a larger non-stiffness than the overpass composed of one mold, and the gap between the overpass 10 and the girder 4, 4 ') And the connecting cross beams (6) .. are distributed by the shear force of each mold (1) (1') (2) (2 '), so that the shear stress and bending force acting on the flange It is effective in dispersing the film stress, and as the width of the overpass becomes longer, it is inevitable to change it into a multi-vertical orientation, which ensures safety and eases the construction, and also increases the effective flange area of the multi-pass viaduct. As it is wide, the thickness of the flange can be reduced and the shape of the girder pedestals 3 and 3 'can be narrowed toward the center, so that the amount of the members of the girder pedestals 3 and 3' can be reduced. At the same time, the effect of constructing an overpass 10 with a beautiful appearance The.
