AI Technical Summary
Technical Problem
In existing technologies, the connection between precast floor slabs and precast beams mainly relies on pre-embedded bolts, resulting in low connection strength and easy loosening, which affects the stability and safety of the overall structure.
Method used
The design employs a combination of inserts, slots, round holes, a first spring, and a limiting mechanism. The inserts are inserted into the slots and initially fixed using the spring's rebound force. The locking mechanism and pre-embedded bolts further secure the connection, resulting in a high-strength connection.
Benefits of technology
This significantly improves the connection strength and reliability between precast floor slabs and precast beams, ensuring the stability and safety of the building structure.

Abstract
The utility model discloses a connecting structure of prefabricated floor slabs, and belongs to the technical field of prefabricated floor slab connection. Comprising a prefabricated beam and a prefabricated wallboard body, an inserting groove and a round hole are formed in the prefabricated beam and communicate with each other, a moving plate is slidably connected to the interior of the inserting groove, a first spring is fixedly connected to one side face of the moving plate, and the other end of the first spring is fixedly connected with the inner wall of the round hole; the face, close to the prefabricated beam, of the prefabricated wallboard body is fixedly connected with an inserting block, and through cooperation of the inserting block, an inserting groove, a round hole, a first spring and a limiting mechanism, when the inserting block is inserted into the inserting groove, a limiting inserting plate can be inserted into a limiting groove under pushing of a second spring, axial limiting of the inserting block is achieved, and the inserting block is effectively prevented from being disengaged; preliminary fixation of the prefabricated beam and the prefabricated wallboard body is achieved, then further fixation is achieved through the embedded bolts, and the overall connection strength and reliability can be remarkably improved.
