Abstract
The utility model relates to a simple trolley for planting steel bars on a plate girder, which comprises a lower platform, an upper platform and a suspension cage; the bottom of the lower platform is provided with a travelling wheel, one end of the lower platform is provided with a balance weight, the other end of the lower platform is welded with the upright post, the rear end of the upper platform is welded with the upright post, and the front end of the upper platform is welded with the upper end of the suspension cage. During construction, the lower platform moves on the bridge along the bridge direction, the suspension cage is suspended outside the bridge, and constructors enter the suspension cage from the upper platform to plant bars, so that the operation is not limited by the terrain under the bridge, and the construction is convenient.
Description
Technical Field
The utility model belongs to the technical field of the road construction, a highway reconstruction and extension construction is related to, concretely relates to simple and easy dolly that is used for widening existing bridge, at the existing beam slab outside bar planting.
Background
In the construction of reconstruction and extension of highways, for small and medium-sized existing bridges on a reconstruction and extension road section, steel bars are usually planted on the outer sides of beam slabs, and wet joints are poured and widened. At present, the plate girder embedded steel bars are usually constructed under a bridge by adopting a climbing vehicle, so that the cost is higher, the limitation by the terrain is larger, and the movement is inconvenient.
