Description

Technical Field

[0001] This utility model relates to the field of precast beam erection at ramp intersections, specifically to an overall transverse support structure for a ramp intersection bridge erection machine. Background Technology

[0002] Currently, precast beams are usually erected using bridge erecting machines or lifted by cranes. However, this construction method still has many problems for the erection of precast beams at the intersection of ramps in mountainous areas: (1) For bridges crossing gullies, canyons, and steep slopes in mountainous areas, cranes cannot be used to erect beams in areas with complex terrain. (2) Due to terrain limitations, the beam transport channel at the intersection can only meet the needs of transport from the ramp branch to the merging point. Because the beams at the merging point have already been erected and there is a height difference, the bridge erecting machine cannot move laterally to erect beams. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides an integral transverse support structure for a bridge erecting machine at a ramp intersection. This structure is applied to the intersection of a ramp and the main line. The beam erection sequence is limited by the terrain and can only meet the on-site hoisting sequence of bifurcation point → merging point. The bridge deck width changes from wide to narrow, which causes the middle support leg track of the bridge erecting machine to be suspended in the air, making it impossible to erect beams. This structure is composed of steel pipes, steel sections, steel wire ropes, etc., arranged on the cap beam, providing a stable transverse support structure for the bridge erecting machine.

[0004] This utility model is implemented as follows: A lateral movement support structure for a ramp intersection bridge erecting machine is constructed, characterized in that: the structure includes steel pipe columns, a steel main beam, steel diagonal braces, steel wire ropes, and anchor bars; the steel pipe columns are arranged at certain intervals on the top of the cap beam, serving as the foundation for the steel main beam and bridging the height difference of the bridge erecting machine's lateral movement track; slots are opened at the top of the steel pipe columns to provide support for the steel main beam, which is arranged within the slots on the top of the steel pipe columns to support the lateral movement track of the bridge erecting machine; the steel diagonal braces connect the steel pipe columns into a whole, ensuring its lateral stability; steel wire ropes are used to connect the support to the flange reinforcement of the already erected beam slab to ensure overall lateral stability; anchor bars are arranged at the bottom of the steel pipe columns, fixing the steel pipe columns to the top of the cap beam.

[0005] This utility model has the following advantages: This utility model provides an overall transverse support structure for a bridge erecting machine at a ramp intersection. This structure is applied to the intersection of a ramp and the main line. The beam erection sequence is limited by the terrain and can only meet the on-site hoisting sequence of bifurcation point → merging point. The bridge deck width changes from wide to narrow, resulting in the suspension of the support track of the bridge erecting machine and the inability to erect beams. This structure is composed of steel pipes, steel sections, and steel wire ropes arranged on the cap beam to provide a stable transverse support structure for the bridge erecting machine. For this structure: (1) This structure is simple in form, easy to install, and the prefabricated structure can be reused. (2) This structure can provide a stable and reliable transverse support structure for the transverse track of the bridge erecting machine without the need for large equipment. It is low in cost and high in efficiency. Attached Figure Description
