Abstract:
The external facade of Chengdu Raffles Plaza Engineering adopts plain concrete finishing. The structural component has large cross section and the design requires that through-wall screw rod shall not be used. Therefore, during the construction of plain concrete finishing with large cross section and without through-wall screw rod, the selections of formwork surface, back edge system and formwork connection system are optimized, the design of plain concrete finishing formwork is deepened, and key points and construction requirements are put forward during process, installation and reinforcement of formwork.
