Description

Technical Field

[0001] The utility model belongs to the technical direction of building construction, and particularly relates to a portable construction platform suitable for chiseling the web of a cantilever-cast beam. Background Technique

[0002] A cantilever-cast concrete beam is a composite structure formed by combining cantilever-cast segments and a weak layer. When the bonding effect of new and old concrete at the joint is not ideal, a weak layer appears at the joint of the beam body, causing the concrete of the cantilever-cast beam to crack and break, resulting in a decrease in the stability of the bridge structure. The weak layer at the segment joint reduces the continuity and integrity of the box girder structure, and significantly reduces its bending and shear resistance. Therefore, it is necessary to chisel the parts with obvious protrusions on the concrete surface and the smooth concrete surface, remove the loose concrete and floating slurry on the surface, and repair the obvious depressions. The traditional chiseling of cantilever-cast beam segments is carried out by setting up a suspension ladder, which is extremely dangerous during construction, the operation is very inconvenient, and the suspension ladder cannot be fixed, resulting in poor chiseling effect and long construction time. Based on this, a chiseling construction platform with low cost, simple erection method, convenient for chiseling construction and taking safety into account is needed. Content of the Utility Model
