A certain project is a construction general contracting project, with B1 and B2 towers on the 27th to 30th floors.
The design adopts a cantilevered cast-in-place concrete structure belt, with a maximum cantilever length of 6m.
There are also 20 standard floors above it.
Due to the fact that the cantilever concrete structure must be constructed together with the corresponding floor cast-in-place structure, the climbing frame needs to stop climbing when the structure is constructed to this point.
The cantilever frame is erected at high altitude for the structural construction of the cantilever part.
After the construction is completed, a second assembly and installation of the climbing frame are required for the upper structure construction.
The process is complex and has a great impact on the construction period.
Moreover, the installation and dismantling of the formwork system at high altitude is difficult and poses extremely high safety risks.
The construction period and labor costs are high.
Therefore, based on factors such as project duration, safety, and cost, changes must be implemented.
