It is easy to achieve the effect of reducing the overall air and construction costs.

본 발명의 구체적인 구성 및 수행 과정을 첨부된 도면을 통하여 설명하면 다음과 같다.The detailed configuration and implementation process of the present invention will be described with reference to the accompanying drawings.

우선 도 4 및 도 5는 각각 본 발명이 적용된 가설교량 및 본교량의 대표 횡단면도 및 종단면도로서, 동 도면을 통하여 알 수 있는 바와 같이, 가설교량의 지주(210)가 보수 대상 본교량상판(101)을 관통하여 본교량의 교각(102) 상단에 고정됨으로써 별도의 기초구조물(103) 없이 본교량의 기초구조물(103)을 공유하게 됨을 알 수 있다.4 and 5 are representative cross-sectional and longitudinal cross-sectional views of a temporary bridge and a main bridge to which the present invention is applied, respectively, and as can be seen from the same figure, the pillar 210 of the temporary bridge is a main bridge deck 101 to be repaired. It can be seen that the base structure 103 of the bridge without sharing a separate foundation structure 103 by being fixed to the top of the bridge 102 of the bridge through the).

따라서, 가설교량을 설치하기 위한 기초공사 및 가물막이 공사 등의 공종이 생략될 뿐 아니라, 가설교량과 본교량의 평면선형이 일치하므로 별도의 우회도로의 시공 또한 불필요하여, 소요 교통 소통 능력을 확보하면서도 공기를 획기적으로 단축하고 공사비 또한 절감할 수 있다.Therefore, not only the construction work such as foundation work and temporary screening work for installing the temporary bridge but also the flat linearity of the temporary bridge and the main bridge coincide, so the construction of a separate bypass road is unnecessary, thus securing necessary traffic communication capability. At the same time, it can drastically shorten the air and reduce construction costs.

도 6은 본 발명의 수행과정을 순차적으로 도시한 것으로, 도시된 실시예는 본교량상판(101) 전체를 교체하는 공사과정이며, 교각(102) 상부 지점 본교량상판(101)에 절개부(109)를 형성한 후, 가설교량 지주(210)의 하단을 절개부(109)를 관통하여 교각(102) 상단에 고정하고 지주(210) 상부에 가설교량상판(220)을 설치함으로써 가설교량을 조립하는 과정과, 가설교량을 통하여 교통량을 처리하면서 노후된 본교량상판(101)을 신설 본교량상판(101a)으로 교체한 후 가설교량을 해체하는 교량보수의 전과정이 나타나 있다.6 is a view illustrating the process of the present invention sequentially, the illustrated embodiment is a construction process for replacing the entire bridge deck 101, the pier 102, the upper section of the bridge bridge 101 incision ( After forming the 109, the lower end of the temporary bridge strut 210 is fixed to the top of the pier 102 through the incision 109 and the temporary bridge upper plate 220 is installed on the upper pillar 210 by installing the temporary bridge The process of assembling and replacing the old main bridge deck 101 with the new main bridge deck 101a while processing traffic through the temporary bridge is shown in the whole process of bridge repair to dismantle the temporary bridge.

통상의 교량은 교각(102) 상단에 보(beam)(110)와 같은 주 구조체가 교좌장치(111) 등을 통하여 설치되고, 그 위에 상판이 설치되므로, 상판 하부면과 교 각(102) 상단은 소정 거리 이격될 수 밖에 없으며, 따라서 교각(102) 직 상부지점의 본교량상판(101)을 절개함으로써 지주(210)를 본교량상판(101)을 관통하여 교각(102)에 설치할 수 있다.In a typical bridge, a main structure such as a beam 110 is installed at an upper end of a pier 102 through a bridge device 111, and an upper plate is installed thereon, so that an upper surface of the upper plate and an upper pier 102 are provided. May be spaced apart from each other by a predetermined distance, and thus, the pillar 210 may be installed in the pier 102 by cutting the main bridge deck 101 at an upper point of the bridge 102.

특히, 도 7에서와 같이 교각(102)의 상부지점은 일종의 분할부로서 본교량상판(101)이 구조적으로 완전 분할되고 상부면에는 신축 조인트(107) 등이 설치되는 경우가 대부분이므로, 절개부(109)의 형성이 더욱 용이할 뿐 아니라, 절개부(109)의 형성으로 인하여 시공중 본교량의 구조적 안정성이 저해될 가능성도 미미하다.In particular, as shown in Figure 7, the upper point of the bridge 102 is a kind of divided part, so that the main bridge plate 101 is structurally completely divided, and the expansion joint 107 or the like is mostly installed on the upper surface, so that the incision is made. In addition to the easier formation of the 109, the formation of the cutout 109 has a slight possibility that the structural stability of the main bridge during construction is impaired.

또한, 절개부(109)의 형성 내지 가설교량상판(220)의 조립과정에 이르는 가설교량 설치 전공정에 있어서도 여타 가설교량에 비하여 시공에 필요한 공간을 최소화할 수 있으므로 교통 소통 장애요인을 최소화할 수 있다.In addition, in the entire process of installing the temporary bridge from the formation of the cutout 109 to the assembling of the temporary bridge deck 220, the space required for construction can be minimized compared to other temporary bridges, thereby minimizing traffic communication obstacles. have.

본교량상판(101)에 대한 교체가 이루어지는 경우, 신설 본교량상판(101a)에는 구 본교량상판(101)의 절개부(109)에 해당하는 개방부(108)를 형성하여 보수공사 완료시까지 지주(210)의 설치공간을 확보하며, 보수공사가 완료되어 본교량상판(101a)을 통한 부분적인 교통 소통이 재개되면 지주(210)를 비롯한 가설교량을 해체하고, 개방부(108)를 충전함으로써 본교량상판(101a)을 완성하게 된다.When the replacement of the main bridge deck 101 is made, an opening 108 corresponding to the cutout 109 of the old main bridge deck 101 is formed in the new main bridge deck 101a until the completion of the repair work. When the installation space is secured and the repair work is completed and partial traffic communication through the bridge deck 101a is resumed, the temporary bridge including the support 210 is dismantled and the opening 108 is charged. This bridge deck 101a is completed.

한편, 도 8 내지 도 11은 교각(102)의 훼손 없이 지주(210)를 교각(102)에 고정할 수 있도록 하는 고정장치(300)를 도시한 것으로서, 일단 교각(102) 상부에 고정장치(300)를 고정한 후 이 고정장치(300)에 지주(210) 하단을 고정함으로써 교각(102)에 지주(210)를 고정하기 위한 앵커 등을 타입하지 않고도 지주(210)를 견고하게 고정할 수 있게 된다.Meanwhile, FIGS. 8 to 11 illustrate a fixing device 300 for fixing the support 210 to the pier 102 without damaging the pier 102, and once the fixing device is formed on the pier 102. After fixing 300, the support 210 can be fixed to the bottom of the support 210 so that the support 210 can be firmly fixed without having to type an anchor for fixing the support 210 to the piers 102. do.

도 8은 기본적인 형태의 고정장치(300)로서, 하부면이 교각(102)의 상단면에 밀착되고 상부면에는 지주(210)가 고정되는 평판(310)과, 교각(102) 상단의 폭과 일치하도록 이격되어 평판(310) 양단부에 설치된 한 쌍의 측판(320)으로 구성되며, 단면계수 확보 등의 목적으로 양측단에 보강플랜지(309)가 접합될 수도 있다.8 is a fixing device 300 of a basic form, the lower surface is in close contact with the upper surface of the pier 102, the upper surface and the support plate 210 is fixed to the upper surface and the width of the upper end of the pier 102 and It is composed of a pair of side plates 320 spaced apart to coincide with both ends of the flat plate 310, the reinforcing flange 309 may be joined to both ends for the purpose of securing the cross-sectional coefficient.

도시된 실시예에서는 고정장치(300)의 평판(310) 상부면에 다수의 결합나사(308)가 형성되고 이 결합나사(308)에 지주(210)의 하단부가 결합되는 구성이 나타나 있으나, 고정장치(300)와 지주(210) 간의 결합수단은 현장 여건에 따라 리벳, 용접 등 다양한 변형이 가능하므로 이에 대한 청구범위의 구체적인 한정은 하지 않는다.In the illustrated embodiment, although a plurality of coupling screws 308 are formed on the upper surface of the flat plate 310 of the fixing device 300, the lower end of the support 210 is coupled to the coupling screw 308, but fixing is shown. Coupling means between the device 300 and the strut 210 is not limited to the specific scope of the claims because it can be modified in various ways, such as rivets, welding depending on the site conditions.

상기 기본형 고정장치(300)는 매 시공시마다 교각(102)의 치수에 따라 고정장치(300)를 제작하여야 할 뿐 아니라, 양 측판(320)과 교각(102)의 측면 간에 미세한 간극이 형성될 수도 있는데, 도 9 내지 도 11에서와 같은 가동형 고정장치(300)를 통하여 이러한 문제를 해결할 수 있다.The basic type fixing device 300 should not only manufacture the fixing device 300 according to the size of the bridge 102 at each construction, but also a minute gap may be formed between both side plates 320 and the sides of the bridge 102. However, such a problem can be solved through the movable fixing device 300 as shown in FIGS. 9 to 11.

즉, 도 10에서와 같이, 평판(310) 양단에 회동축(341)을 통하여 회동가능하도록 설치된 회동암(arm)(340)과, 평판(310) 양단의 회동암(340) 상단에 양단이 각각 힌지(hinge)연결된 신축봉(330) 및 평판(310) 양단의 회동암(340) 하단에 각각 힌지연결된 한 쌍의 측판(320)으로 고정장치(300)를 구성하여, 신축봉(330)이 신장(伸長)됨에 따라 측판(320)이 교각(102) 측면에 밀착되도록 함으로써 더욱 견고한 고정이 가능하다.That is, as shown in Figure 10, both ends of the rotating arm (340) and the upper end of the rotating arm (340) installed on both ends of the flat plate 310 through the rotating shaft (341) Each of the fixing rods 300 by hinge pairs of elastic rods 330 and a pair of side plates 320 hinged to lower ends of the pivot arm 340 at both ends of the flat plate 310, respectively, elastic rods 330. As the elongation is made, the side plate 320 is brought into close contact with the side of the piers 102, thereby enabling more firm fixing.

여기서 신축봉(330)은 그 길이가 기계적으로 변화될 수 있는 구성요소로서, 도 11에서와 같이, 서로 반대방향의 나사선을 가진 한 쌍의 수나사(332)가 암나사(331)에 결합되어 암나사(331)를 회전시킴에 따라 신장 또는 수축되는 일종의 턴버클 형태의 구성을 예로 들 수 있다.Here, the elastic rod 330 is a component whose length can be changed mechanically, and as shown in FIG. 11, a pair of male threads 332 having threads in opposite directions to each other are coupled to the female screw 331 to allow female screws ( For example, a configuration of a kind of turnbuckle that extends or contracts as the 331 is rotated.

이러한 신축봉(330)은 동일한 방향의 나사선을 가지는 수나사(332)를 사용하는 대신 암나사(331) 양측의 나사선 방향을 서로 반대가 되도록 구성할 수도 있고, 암나사(331)의 불요 회전을 방지하기 위한 핀(pin)을 설치하는 등 다양한 변형이 가능하며, 이는 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 선택 실시할 수 있는 사항이므로 이에 대한 청구범위의 구체적인 한정은 하지 않는다.The elastic rod 330 may be configured to be opposite to the direction of the screw thread on both sides of the female screw 331, instead of using the male screw 332 having the thread in the same direction, to prevent unnecessary rotation of the female screw 331 Various modifications are possible, such as installing a pin, which is a matter that can be carried out by one of ordinary skill in the art to which the present invention pertains, and thus the specific scope of the claims is not limited thereto.

이렇듯, 신축봉(330)에 의하여 회동되는 회동암(340)이 측판(320)을 교각(102) 측면에 밀착시키는 고정장치(300)를 통하여 다양한 치수의 교각(102)에 대하여 동일한 고정장치(300)를 사용할 수 있어 고정장치(300)의 재활용이 가능할 뿐 아니라, 더욱 견고한 지주(210)의 고정이 가능하게 된다.As such, the pivoting arm 340 rotated by the elastic rod 330 has the same fixing device for the pier 102 having various dimensions through the fixing device 300 for bringing the side plate 320 into close contact with the pier 102. 300 can be used to enable the fixing of the fixing device 300, as well as to more secure the holding of the support (210).
