A modular prefabricated building floor structure
This invention belongs to the field of modular prefabricated floor slab technology, and more particularly to a modular prefabricated building floor slab structure, including a floor slab body. Multiple locking mechanisms and multiple U-shaped reinforcing bars are equally spaced on both sides of the floor slab body. The locking mechanisms and U-shaped reinforcing bars on both sides of the floor slab body are centrally symmetrically distributed. Each locking mechanism includes a box detachably mounted on the floor slab body. Inside the box is a unidirectional rotating column, and two centrally symmetrically distributed levers are fixedly mounted on the side of the rotating column. This invention, by setting multiple sets of cooperating locking mechanisms and U-shaped reinforcing bars between adjacent floor slab bodies, applies active traction force to the slabs during splicing, creating reliable pre-stress at the joint, transforming "passive filling" into "active pressing," effectively overcoming the problem of penetrating micro-cracks caused by inconsistent drying shrinkage deformation in traditional post-cast strips.
