Abstract

The present application describes a bridge sliding device and construction system. The device includes a slide rail assembly, a first sliding component on the rail, and a second sliding component on the first. The second component locks at the start of the first, and the bridge deck truss's weight causes the first component's end to tilt slightly, allowing it to easily cross the junction between the temporary support platform and the bridge pier. This facilitates the smooth crossing of both the first and second components over the junction. Once the first sliding component is in place, the second component unlocks and continues sliding, increasing the travel distance of the bridge deck truss. The system ensures smoother movement of the components, enhancing construction efficiency.

Dependent claims

A bridge sliding device, comprising:

a slide rail assembly, the slide rail assembly comprising a rail configured to span across a temporary support platform and a bridge pier, the rail arranged along a transverse direction from the temporary support platform toward the bridge pier;
a first sliding component slidably disposed on the rail, the first sliding component having a sliding start end and a sliding end opposite each other in the transverse direction;
and
a second sliding component unlockably locked to the sliding start end of the first sliding component, the second sliding component capable of sliding from the sliding start end to the sliding end of the first sliding component, the second sliding component configured to support a bridge deck truss, wherein the length of the second sliding component is less than the length of the first sliding component, and the length of the first sliding component is less than the length of the rail.
