Construction and implementation method for tool type anchoring end of overhung external scaffold profile steel beams

The invention relates to a construction and implementation method for a tool type anchoring end of overhung external scaffold profile steel beams. A scaffold support, a main standard keel, auxiliary standard keels, small standard formworks, seam splicing formworks, standard formworks, PVC sleeve pipes, U-shaped bolts, profile steel beams, seam splicing formworks, plugging battens and heating steel plates are included, wherein the scaffold support is built through phi 48 steel tubes, adjustable supporting heads are arranged on the top of the scaffold support, the main standard keel is arranged on the scaffold support in the full length, the auxiliary standard keels are arranged on the main standard keel in the perpendicular direction of the main standard keel, the small standard formworks, the seam splicing formworks and the standard formworks are arranged at the upper end of the auxiliary standard keels and used for carrying floor slab concrete, the PVC sleeve pipes penetrate through the concrete, the U-shaped bolts penetrate into steel cushion plates and are sleeved with the PVC sleeve pipes, the seam splicing formworks are arranged below the profile steel beams and on auxiliary non-standard keels and used for carrying cement mortar, the plugging battens are arranged perpendicular to the two ends of the seam splicing formworks in the length direction, and the heating steel press plates press the profile steel beams and are fixed through nuts. The safety of the profile steel beam anchoring end can be effectively improved, the U-shaped bolts, the steel cushion plates, the formworks, the auxiliary non-standard keels and the battens can be tooled and used repeatedly, the material cost is greatly lowered, hard blocks formed by the cement mortar can be scraped and then used for rod padding, the installation speed is high, and the construction speed is increased.
