Description

Technical Field

[0001] This utility model relates to the field of continuous beam construction technology, and more specifically, to a working platform for the installation and tensioning of continuous beam brackets. Background Technology

[0002] Continuous beams are beam structures with three or more supports. They belong to statically indeterminate systems and are widely used in construction, bridge engineering, and other fields. Their core definition is a beam with three or more support points, fixed at both ends by supports, and with at least one additional support in the middle to form a continuous support structure. Continuous beam brackets are temporary support systems used in bridge construction to support continuous beam structures. They are mainly used in cantilever casting or sliding construction processes, primarily for the construction of the 0th block of high-pier, large-span continuous beams. By adjusting the bracket's alignment to match the base plate, a low-settlement or differential-settlement support effect is achieved. However, the installation of existing continuous beam brackets involves a large workload and has poor construction safety. Therefore, we propose a working platform for the installation and tensioning of continuous beam brackets. Utility Model Content
