US Patent 12024884 Continuous FRP composite fiber truss shear connector

A continuous FRP composite fiber truss shear connector is provided. The connector includes two folding line segments I and multiple folding line segments II. Multiple folding line segments II are connected in sequence end to end, and the two folding line segments I are respectively connected to the head end of the first folding line segment II and the tail end of the last folding line segment II; and the included angle between the adjacent folding line segments II is 20°-140°. The present disclosure achieves the rigid connection strength of walls, and can cut off thermal bridge connection so as to greatly improve the thermal insulation efficiency of precast concrete sandwich panels.
