The utility model relates to a split type anchoring part which comprises an anchoring bottom plate, and the anchoring bottom plate is provided with a steel plate layer and a demolding layer. The lowerends of the two anchor bolts are welded on the anchoring bottom plate to form a steel plate type embedded part; the anchoring bottom plate is embedded in the lower end face of the truss laminated slab, and the demolding layer is tightly attached to the bottom of the truss laminated slab. The anchor bolts penetrate through the upper end surface of the truss laminated slab and are 110-140 mm higherthan the upper end surface; an isolation layer is arranged around the anchor bolt; the section steel cantilever frame is placed on the top surface of a floor layer formed by pouring on the truss laminated slab after the truss laminated slab is mounted, and is positioned between the two anchor bolts; the first ends of the two connecting sleeves in the first group are in one-to-one correspondence with the tops of the two anchor bolts and are detachably connected with the tops of the two anchor bolts; the bottoms of the two connecting rods are in one-to-one correspondence and are detachably connected with the second ends of the two connecting sleeves of the first group; two through holes are formed in the positions, corresponding to the two connecting rods, of the pressing plate; and the topends of the two connecting rods penetrate through the two through holes and are correspondingly and detachably connected with the two connecting sleeves of the second group.
