THE SUPPORT STRUCTURE OF MOVABLE SCAFFOLDING SYSTEM IN BRIDGE CONSTRUCTION

摘要

The present invention relates to a support structure of a mobile scaffold for bridge construction.;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. A pair of horizontal supporters 10 on which a bridge beam (GB) of a mobile scaffold supporting a bridge plate (Bg) and a formwork (F) is placed, and the pair of horizontal supporters of the piers (P) Consists of several connecting bolts (Bt) pressed on the top and the holding base 20 for supporting the horizontal support 10 to the upper surface of the lower support (Pa) of the piers, so that the load transmitted from the mobile scaffold It has a technical configuration to transfer directly to the lower pedestal (Pa) of the bridge through the horizontal pedestal (10) and the holding posts (20), when the construction of the deep mountain or river area, which is very high from the lower pedestal to the upper part of the bridge Before of prop (20) Therefore also proportional to form a very high height, holding for installation was a large number of materials and manufacturing consumption airborne and assemblers and yiettara defect becomes even rod installation costs of 20.;The present invention solves these shortcomings, the support structure is provided with support holes in the upper both sides of the pier and the horizontal support each has a fitting projection which is supported across the lower jaw of the support holes, the connection bolt They are characterized in that through the two fitting projections to connect the horizontal support firmly to the support holes at the top of the piers mutually, acting on the props while bearing a substantial portion of the load acting on the horizontal support It is characterized by providing a supporting structure of mobile scaffolding, which makes it possible to easily construct struts, thereby greatly reducing labor and costs due to the manufacture, installation, dismantling and movement of struts. will be.
