Long-span Unbonded Prestressed Cast-in-place Hollow Floor Structure Construction Technique
The education and teaching comprehensive building project of Wuhan Institute of Technology covers a construction area of 30,346 m2. According to the functional requirements, the lecture hall is a large-span cast-in situ concrete structure with post-tensioning unbonded prestressed hollow floor technology. The filling material of the hollow floor is LPM (the main material is polystyrene foam). In the construction process, targeted measures have been formulated in the aspects of material selection and construction technology, especially effective measures have been adopted in the aspects of anti-floating of hollow plates, linear fixation of prestressed tendons, cyclic grading tensioning of prestressed tendons, anti-rust of prestressed tendons, etc. The above measures have achieved good results through tensile testing and physical inspection of the main structure after the removal of the template. Effectively ensure the construction quality. Using this technology, the floor weight and beam structure size are greatly reduced, and good economic benefits are obtained, which is in line with the requirements of building industry policy.
