Anti-floating anchorage device for super-thick concrete dense rib floor system

The utility model provides an anti-floating anchorage device for an ultra-thick concrete dense rib floor system, and relates to the technical field of building construction. The problems that an existing super-thick concrete dense rib floor system anti-floating anchor is not provided with a dense rib adaptive structure, and secondary damage is extremely likely to be caused by connection at dense rib gaps are solved. Comprising an anchoring connecting piece; the anchoring connecting piece is in threaded connection with a tensioning positioning piece; the tensioning positioning piece is sleeved with a floor system pressing piece. The floor system pressing piece is connected with a telescopic dense rib adapting piece in a sliding mode. The four telescopic dense rib adapters are connected with dense rib fixing pieces in a sliding mode. Two anchoring welding grooves are formed in the anchoring connecting cylinder; the device can assist in sliding and stretching to adapt to the position of the dense rib, enables th
