Support connecting structure of truss reinforced concrete laminated slab

The utility model discloses a support connecting structure of a truss reinforced concrete laminated slab, which relates to the technical field of building construction, and is characterized in that an anchoring rod is fixed on the inner side of a beam stirrup through the matching action of an inner pipe sleeve, an outer pipe sleeve and an extension spring. The operation that an anchoring rod penetrates into the inner side of an anchoring hook from one side of a beam stirrup is not needed, operation is more convenient, when a cast-in-place beam steel reinforcement framework formed by binding and fixing a beam longitudinal bar and the beam stirrup is pulled through the adjustable shifter, the extension spring is stressed and stretched, and the limiting effect of the outer pipe sleeve and the extension spring is matched, so that the cast-in-place beam steel reinforcement framework is fixed. Unnecessary displacement of prefabricated bottom plate concrete cannot be caused, the relative fixing stability of the anch
