an operation platform for an arch bridge arch frame of a suspension splicing type comprises an operation platform, a group of adjustable fixed pipes and a group of inverted U-shaped steel bases, wherein the operation platform is horizontally arranged for an operator to stand, the group of adjustable fixed pipes are vertically fixed on the bottom surface of the front end of the operation platform, and the group of inverted U-shaped steel bases are vertically fixed on the bottom surface of the rear end of the operation platform; the adjustable fixing pipe comprises a steel pipe, a bottom adjusting bracket and a limiter, wherein one end of the steel pipe is fixed on the bottom surface of the operating platform, the upper part of the bottom adjusting bracket is sleeved in the other end of the steel pipe, the limiter is arranged on the steel pipe and used for fixing the steel pipe and the bottom adjusting bracket, and the other end of the bottom adjusting bracket is fixed on an arch bridge arch frame; the inverted U-shaped steel base is provided with a bolt hole, and the inverted U-shaped steel base is fixed on the arch bridge arch frame through the insertion of the connecting bolt into the bolt hole.
Further, the set of adjustable fixed pipes is arranged in parallel with the set of inverted U-shaped steel bases.
Further, the group of adjustable fixed pipes and the group of inverted U-shaped steel bases are respectively provided with 3.
Further, two bolt holes are formed in the inverted U-shaped steel base.
Further, a connecting seat is arranged at the bottom of the bottom adjusting bracket.
Further, the operation platform comprises a frame welded by angle steel on four sides, a group of phi 12 steel bars uniformly welded on the frame, and a bamboo plywood arranged on the frame.
The utility model has the beneficial effects that:
compared with the traditional scaffold platform, the scaffold platform has the advantages of simple manufacture, strong applicability, quick erection, convenient installation and disassembly, repeated turnover and use, large operation range in the construction of the suspended spliced arch bridge arch frame, reduced construction risk of operators, improved construction efficiency and reduced cost, and can be used for the suspended spliced construction of municipal administration, roads and bridges.
