Abstract

본 발명은 교량공사용 이동식비계의 지지구조에 관한 것이다.The present invention relates to a support structure of a mobile scaffold for bridge construction.

교각과 교각사이에 설치되어 비계의 해체없이 이동식으로 교량의 상부구조를 한 경간씩 시공해 나가는 이동식비계공법에 사용되는 종래의 이동식비계의 지지구조는, 제1도와 같이 교각(P)의 상부양측면에서 교량상판(Bg)과 거푸집(F)을 받치는 이동식비계의 박스보(GB)가 올려 놓여지는 한 쌍의 수평받침대(10)들과, 상기 한 상의 수평받침대들을 상호간에 교각(P)의 상단에 압박하는 수개의 연결보울트(Bt)들과, 상기 수평받침대(10)들을 교각의 하부 받침대(Pa) 상부면에 받쳐주는 지주대(20)들로 구성되어서, 이동식 비계에서 전달되는 하중을 수평받침대(10)들과 지주대(20)들을 통하여 교각의 하부받침대(Pa)에 직접 전달하는 기술적 구성을 가졌는바, 교각의 하부받침대로부터 교각상부까지가 매우 높은 깊은 산중이나 하천지역의 공사시에는 지주대(20)의 전체높이도 비례하여 매우 높게 형성되므로, 지주대(20)의 설치에 많은 자재와 제작공수 및 조립공수가 소모되고 이에 따라 설치비용도 막대해지는 결함이 있었다.The supporting structure of the conventional mobile scaffolding used for the mobile scaffolding method, which is installed between the pier and the pier, and constructs the upper structure of the bridge by one span without disassembly of the scaffold, is the upper both sides of the pier P as shown in FIG. At the top of the bridge (P) and a pair of horizontal pedestals (10) on which the bridge beam (GB) of the mobile scaffold supporting the bridge deck (Bg) and the formwork (F) is placed, Consists of several connecting bolts (Bt) for pressing on, and the struts 20 for supporting the horizontal support (10) to the upper surface of the lower pedestal (Pa) of the piers, so that the load transmitted from the mobile scaffold is horizontal Through the pedestals 10 and the support poles 20, the technical configuration of direct transmission to the lower pedestal of the pier, the construction of a deep mountain or river area is very high from the lower pedestal to the upper pier Before props (20) Since the height of the body is also very high in proportion, there is a defect in that a lot of materials and manufacturing labor and assembly labor is consumed in the installation of the holding stage 20, and accordingly the installation cost is enormous.

본 발명은 이러한 단점들을 해결하고져, 지지구조의 구성을 교각의 상부 양측면들에 지지구멍들을 구비하고, 수평받침대들에는 각각 상기 지지구멍들의 하부턱에 걸쳐져서 지지되는 끼움돌출부를 구비하며, 상기 연결보울트들은 상기 양측 끼움돌출부들을 관통하여 수평받침대를 교각의 상단에 지지구멍들에 상호간에 견고하게 연결시킴을 특징으로 하여, 수평받침대에 작용하는 하중의 상당부분을 교각으로 감당케하므로서 지주대에 작용하는 하중을 경감시키기 때문에, 지주대를 간단히 구성할 수 있도록 함으로써, 지주대의 제작과 설치 및 해체와 이동에 따른 작업공수와 비용을 대폭 절감할 수 있도록 하여주는 이동식비계의 지지구조를 제공함에 특징이 있는 것이다.The present invention solves these shortcomings, and the structure of the support structure is provided with support holes on both sides of the upper part of the piers, and the horizontal supporters are provided with fitting projections which are supported over the lower jaws of the support holes, respectively. The bolts penetrate the two fitting protrusions and firmly connect the horizontal support to the support holes at the top of the piers, thereby acting on the props by bearing the substantial portion of the load applied to the horizontal support to the piers. Since it reduces the load to be carried out, it is possible to easily configure the strut, thereby providing the supporting structure of the mobile scaffold, which can greatly reduce the labor and cost due to the manufacture, installation, dismantling and movement of the strut. It is.
