Abstract

In the construction of the bridge deck using the movable frame works, the works on a job site is composed of a number of unit frameworks (A1,A2,A3....). Each unit framework with rollers is brought into the job site riding the rail which is laid on the floor. The unit frameworks are raised using the oil pressure jack and they are fixed by the stay and the concrete placing of the deck is finished. At the time of the removal of the framework, the stay is taken out by the oil pressure jack. And then the rollers are placed on the rail and the unit framework is moved to the other job site by the rail.

본 발명은 하천의 수심이 얕거나 교각높이가 낮은 교량, 즉 바닥조건이 양호한 교량설치 작업현장에서 교량상판(床板)을 타설키 위한 접지식(接地式) 지보공(支保工)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a grounding-type earthwork for placing bridge decks in bridges with shallow depths of rivers or low bridge heights, that is, bridges with good flooring conditions.

본 발명은 하천의 수심이 얕거나 계곡이 얕은곳 등 바닥조건이 양호한 곳에 적합한 접지식 이동지보공에 관한 것으로, 이와같이 바닥조건이 양호한 곳에서는 주로 고정지보공으로 시공하는 예가 많으나 가설형틀의 제작과 해체에 많은 시간과 인력이 소요되므로 오히려 공사시간이 오래 걸리고 공사비용이 높아지는 등의 결함이 있었던 것이다.The present invention relates to a ground-type mobile ground support suitable for places where the ground conditions are good, such as shallow rivers or shallow valleys, but in many places where the ground conditions are good, there are many examples of construction as a fixed ground construction, but in the manufacture and dismantlement of temporary frames Since it takes a lot of time and manpower, the construction time is long, and the cost of construction is high.

본 발명은 이와같은 점을 고려하여 바닥조건이 양호한 곳에서 이동식 지보공을 사용함으로서 공사기간을 더욱 단축시키고 현장작업 인원을 줄이고 경제적인 시공을 할 목적인 것으로 좀더 상세히 설명하면, 상부에 다수의 받침보를 설치한 박스형의 단위형틀체를 구성시킨 것의 하단에 수개의 로울러를 부착시켜 작업구간에 레일을 타고 이동시키며 유압작키로 약간 들어올린 후 고임틀로 고정시키며 교량상판의 콘크리트타설이 끝나고 양생후 탈형시에는 유압작키로 지지시키면서 고임틀을 제거시킨 후 단위형틀체 하단의 로울러를 레일위에 얹혀지게 한 후 인출해 낸후에 인접작업 구간까지 설치된 레일을 따라 이동케한 것으로, 형틀의 설치 및 해체가 간편하고 이동이 편리하게 한 것으로, 본 발명의 시공방법을 첨부 예시도면에 따라 상세히 설명하면 다음과 같다.In view of the above, the present invention aims to further shorten the construction period, reduce the number of workers in the field work, and economically construct the construction by using a movable supporter at a good floor condition. When several rollers are attached to the bottom of the box-shaped unit frame, the rail is moved to the work area, lifted with a hydraulic key, slightly lifted with a high frame, and the concrete slab of the bridge deck is finished. The rollers at the bottom of the unit frame are placed on the rails after being removed by supporting the hydraulic paddles, and then drawn out and moved along the rails installed to the adjacent work section. In this convenient, the construction method of the present invention will be described in detail according to the accompanying drawings. If follows.

[실시예 1]Example 1

첨부도면 제1도는 본 발명에서 사용되는 단위형틀체(A1,A2,A3…)를 예시하고 있다. 상부에는 다수의 받침보(1)를 설치하고 박스형의 장방형체의 되어 있으며, 하부에는 수개의 로울러(2)를 부착하고 있다.FIG. 1 illustrates unit frame bodies A 1 , A 2 , A 3 ... Used in the present invention. In the upper part, a plurality of support beams 1 are installed, and the box-shaped rectangular body is attached, and in the lower part, several rollers 2 are attached.

이와 같은 단위형틀체(A1,A2,A3…)는 교각(3)과 교각(3) 사이의 한 작업구간에 수개를 설치하는 것이 보통이며(제4도 및 제5도 참조) 그 설치방법에 있어서는 작업구간에 침목과 레일(4)을 설치한 후 단위형틀체를 올려놓고 제위치까지 도달케한 다음 유압작키로 들어올린 후 고임틀(5)을 수개처에 설치하여 고정시키게 되는 것이다(제3도 참조).Such unit frames A 1 , A 2 , A 3 ... Are usually provided with several pieces of work between the piers 3 and the piers 3 (see FIGS. 4 and 5). In the installation method, after installing the sleepers and the rails (4) in the work section, put the unit frame body to reach the position, lifted up by the hydraulic operation key, and then installs the stationary frame (5) in several places. (See Figure 3).

단위형틀체(A1,A2,A3…)의 상부에 형틀용 판넬등을 설치한 후 교량상판(6) 콘크리트 타설 및 양생이 끝난 후 탈형시에는 유압작키를 지지시키면서 고임틀(5)을 제거시키고 단위형틀체를 하강시켜 로울러(2)를 레일(4) 위에 올려놓은 후 인출해 내며, 다음 작업구간까지 설치된 별도의 레일(4')을 따라 이동하게 되는 것이다(제4도 및 제5도 참조).After installing the mold panel etc. on the upper part of unit frame (A 1 , A 2 , A 3 ...), Bridge top plate (6) To remove the unit frame, lower the unit frame, place the roller 2 on the rail 4, and withdraw it, and move along the separate rail 4 'installed until the next work section (FIGS. 4 and 4). See also 5).

이와같이 본 발명에서는 한 개의 작업구간에 필요한 지보공을 수개의 단위형틀체(A1,A2,A3…)로 분리제작하여 단위체의 중량을 가볍게 하고 각 단위형틀체는 레일을 타고 이동케함으로써 작업현장에 설치 및 탈형과 이동이 간편하게 하고 공사기일을 빨리할 수 있고 가설형틀의 파손을 방지하며 현장작업 인력을 극소화함으로써 시공비의 절감을 기할 수 있는 시공방법인 것이다.As described above, in the present invention, the support hole required for one work section is separated into several unit frames (A 1 , A 2 , A 3 ...) To lighten the weight of the unit and each unit frame moves by moving on a rail. It is a construction method that can reduce installation cost by simplifying installation and demoulding and moving on site, preventing construction date, preventing damage to temporary frame, and minimizing field work force.
