Background technique
In recent years, assembled architecture development in China's is swift and violent, and a hundred flowers blossom for various new structural systens, mostly with solid prefabricated
Based on structure, but problems are found in practice process, as prefabricated components side goes out component production automation journey caused by muscle
Spend low, the control of quality caused by live reinforcing bar connects is difficult, and member dead weight leads to greatly that tower crane model is big, on-site hoisting is difficult and fortune
Defeated inconvenience, template caused by post-cast strip connects and reinforcing bar workload are big, and artificial demand is big etc..In this background, it assembles whole
Body formula overlapped shear wall structure is come into being.
Due to the special construction of overlapped shear wall and production technology is overturn, built-in fitting pre-buried difficulty in the second face wall body,
It will appear following several situations in wall production process at this stage: 1, the second face wall body being squeezed by built-in fitting, built-in fitting is buried
Enter the second face wall body, the coarse aggregate in pre-buried second face wall body concrete in the process withstands built-in fitting, influences the pressure of built-in fitting
Enter；2, side form is preset in the second face wall pre-embedded position, stops the concrete in the second face wall body in advance, realization is pre-buried, but side
Mould area occupied is big, and required precision is high, operating difficulties when pre-buried intensive, and pre-buried periphery will form metope gap, increases existing
The cost of field construction.Therefore, complicated for operation in overlapped shear wall production process in the related technology, production efficiency is lower.
