by Precast prestressed double T-plate is a precast concrete component composed of a wide surface and two high and narrow ribs, shaped like two letters T horizontally spliced together, hence it is called a double T-plate.
The surface of the double T-plate serves as both a transverse load-bearing component and a compression zone for longitudinal load-bearing ribs.
It has clear force transmission levels, simple geometric shapes, and good mechanical properties.
It is a highly economical precast component commonly used in large-span floor structures, and has been extensively researched and applied both domestically and internationally.
