Steel structure building assembly type prefabricated floor slab connecting piece

The utility model discloses a steel structure building assembly type prefabricated floor slab connecting piece. The ends of exposed steel bars at the two ends of each prefabricated floor slab are steel bar pier heads additionally provided with base plates; or the end of the exposed steel bar at one end of each prefabricated floor slab is a steel bar pier head additionally provided with a base plate, and the end of the exposed steel bar at the other end of each prefabricated floor slab is provided with an extrusion sleeve; a strip-type steel plate is perpendicularly welded to I-shaped steel beams along the full length of the top faces of the I-shaped steel beams, and the strip-type steel plate is provided with steel bar locating grooves at intervals in the length direction; the prefabricated floor slabs on the two sides of the strip-type steel plate on all the I-shaped steel beams are arranged in a staggered mode, and the exposed steel bars of the prefabricated floor slabs on the two sides of the strip-type steel plate are placed in the steel bar locating grooves in a staggered mode and fixed to the strip-type steel plate through the steel bar pier heads with the base plates additionally mounted at the ends of the steel bar pier heads or the extrusion sleeves. The steel structure building assembly type prefabricated floor slab connecting piece is quite convenient to install and capable of greatly reducing construction processes, saving time for anchoring between the prefabricated floor slabs and the steel beams and improving the anchoring strength of the floor slabs remarkably; the steel structure building assembly type prefabricated floor slab connecting piece can be widely applied to connection between the prefabricated floor slabs and the steel beams in an assembly type steel structure building.
