Project Name: Rongguang longhui Plaza Phase II

Construction unit: Shanghai Construction Group No.5

Project location: Anning District, Lanzhou City, Gansu Province

Service life: 2020-2023

Products used: hydraulic protection screen, hydraulic unloading platform

Structure overview: diamond type super high-rise building, 5.1 meters high, each floor structure changes.

Design difficulties: as the inflection point of the plane straight face is inclined and gradually shrinks inward, in order to prevent the platform and external protection system from gradually extending outward during structural changes,

To ensure the smooth climbing of the frame, special design is carried out for the inflection point part of the unit frame, and the protection system is disassembled and replaced to adapt to the structural contour change,

When the protection system is extended to a certain extent, it is impossible to carry out the protection work, and the transformation process needs to be carried out: remove a group of large protection units,

Two groups of half length small protection units are replaced, one of which is installed on the original straight surface, and the other is directly installed on the slope side,

The vertical side and inclined side protection units are closed by temporary protection on site, and are climbing layer by layer and adjusted layer by layer. After climbing several layers, they enter the next transformation process.
