AI Technical Summary
In existing prefabricated concrete frames, stress concentration is prone to occur at the connection between precast beams and precast columns, which may cause weld cracking, especially under high load or alternating load, thus affecting the seismic performance of the structure.
The connection structure, which consists of a fixed frame, square tube, insert plate, positioning column, baffle, tension spring, ball bearing, etc., is adopted. The precast beams and precast columns are connected by insert slots and bolts to enhance the connection strength and stability.
It improves the overall strength and seismic performance of the concrete frame, reduces stress concentration, and extends the service life of the structure.

Abstract
Claims
1. Reinforced concrete frame structures, including: Precast columns; A precast beam is detachably mounted on the side wall of the precast column; a connecting assembly mates with the precast beam; characterized in that the connecting assembly includes a fixing frame detachably mounted on the precast column, a square tube mounted on the outer wall of the fixing frame, and multiple insert plates mounted on the ends of the precast beam, the square tube allowing the precast beam to pass through, and the precast column having insertion grooves that mate with the insert plates; the fixing frame has a first bolt, and the precast column has a first threaded hole that mates with the first bolt; the connecting assembly further includes a positioning post mounted on the fixing frame, a baffle mounted on the positioning post, and a tension spring sleeved on the positioning post, the fixing frame having a circular hole through which the positioning post can slide, and the precast column having a positioning hole into which the positioning post can be inserted, wherein when the positioning post is aligned with the positioning hole, the first bolt is aligned with the first threaded hole.
2. The concrete frame reinforcement structure of claim 1, wherein: The square tube is provided with a first reinforcing plate at the bottom. One side of the first reinforcing plate is fixed to the bottom of the square tube, and the other side is attached to the outer wall of the precast column.
