Technical Field

[0001] The utility model relates to the construction field of suspension bridges, and particularly to a transverse temporary support structure for bridges. Background Art

[0002] In the construction of long-span suspension bridges, especially under complex wind fields, the bridge girders will have certain transverse and longitudinal displacements. To ensure the installation quality of the transverse wind-resistant bearings of the bridge, it is necessary to provide transverse temporary supports for the girders. For traditional bridge temporary supports, their structures can be referred to the utility model patent of a prior application with the authorization publication number of "CN220013386U".

The transverse temporary support includes an outer cylinder, an inner cylinder and a displacement device. The inner cylinder corresponds to the outer cylinder. The outer cylinder is connected to a backing plate, and the inner cylinder is connected to the displacement device. First and second sealing plugs are arranged at the upper and lower ends of the outer cylinder, and a chamber is formed inside the outer cylinder. The backing plate is fixed to the second distribution beam, and the second distribution beam is fixed to the first distribution beam.

[0005] According to the transverse temporary support structure for bridges of the utility model; the displacement device includes a top plate, a connecting shaft, a support plate and rollers. The top plate and the support plate are integrated, and multiple groups of rollers are arranged on the support plate through the connecting shaft.

[0006] According to the transverse temporary support structure for bridges of the utility model; adjust the depth of the inner cylinder in the outer cylinder according to the required transverse distance, so that the rollers contact the support. The rollers can roll along the bridge direction on the support. Open the first sealing plug, pour fine sand to fill the chamber, and the top plate of the inner cylinder is completely supported on the fine sand. When disassembling, open the second sealing plug, release the fine sand in the chamber, and retract the inner cylinder so that the rollers leave the support.

[0007] The utility model has the following advantages: The utility model provides a transverse temporary bearing structure for a bridge, which adjusts the depth of the inner cylinder in the outer cylinder according to the required transverse distance, so that the roller contacts the support, and the roller can roll along the bridge direction on the support. Open the first sealing plug, pour fine sand to fill the chamber, and the inner cylinder top plate is completely supported on the fine sand. When disassembling, open the second sealing plug, release the fine sand in the chamber, and retract the inner cylinder so that the roller leaves the support.
