Description

Technical Field

[0001] The utility model relates to the technical field of continuous beam construction, in particular to a beam end operating platform suitable for the construction of multiple working surfaces of a continuous beam. Background Art

[0002] The cantilever method of casting continuous beams has the advantages of no need for supports, fast construction speed, and wide application range. After removing the formwork at the beam end, construction personnel need to perform operations such as side formwork removal, prestressed steel strand tensioning, pipe grouting and bottom formwork removal in sequence. When removing the bottom and side formwork and installing the formwork for the next stage, in order to shorten the construction time, the beam end needs to be chiseled and cleaned at the same time, which puts high demands on the applicability and safety of the beam end operating platform.

[0003] The commonly used beam end operating platform is mainly fixed to the tie rods on the inner and outer sides of the web at the end of the beam through a bracket. The beam end operating platform must be removed when the bottom formwork and side formwork are removed and the formwork is installed in the next stage. It can be installed again when the prestressed steel strands are tensioned, the pipes are grouting, and the beam ends are chiseled and cleaned. It is impossible to construct multiple working surfaces at the same time, which increases the construction time and puts higher requirements on the on-site scheduling and management of the construction personnel.
