Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction technology, and specifically relates to a dismantling device for a cap beam construction platform. Background Technology
[0002] During the construction of the bridge pier, a temporary support structure, known as a construction platform, is typically erected to facilitate worker operations, material transportation, and equipment installation. This temporary support structure is removed after the main bridge pier structure is completed. However, maintaining the construction platform long-term poses safety hazards. The platform itself may age and corrode due to prolonged exposure to the natural environment, posing structural safety risks. Furthermore, if the platform obstructs traffic or other facilities beneath the bridge, it can also create potential safety problems.
