These technologies include the scheme of prestress plane lapping,the deep design of transition beam,joints disposal in construction of steel pipe column prestressed beam,wavy pipe locating in prestressed stiff beam,super-long prestressed strands penetrating.

The construction technology for stiffness columns in Xiamen east times plaza;

According to engineering features,considering such conditions:the working of rolled steel shapes materi-als in the columns,the installation of the rolled steel shapes in the columns,the reinforcment work of stiffness columns,the formwork,the concrete work,etc.

We also took a series of technical measures when manufacturing and processing the power armored steel columns and during constructing them.

Strengthen frame beam-column in high-rise building by broadensection method;
