The reliability of node connection is considered, and the feasibility of actual construction operation is also considered, wherein the appropriate connection mode is as follows: and manufacturing the platform beam into a superposed clamping sleeve beam. On one hand, the T-shaped steel beams positioned at the two sides of the independent beam and arranged at the lower part of the superposed clamping sleeve beam are reliably connected with embedded parts in concrete at the two sides of the independent beam by adopting connecting plates and bolts; on the other hand, embedding embedded bolts on the top surface of the independent suspension beam into large-inner-diameter deflection-holding sleeves welded on two sides of long I-steel on the upper part of the superimposed clamping sleeve beam, connecting inner wire sections locally opened at the top ends of the large-inner-diameter deflection-holding sleeves with the embedded bolts by adopting compensation nuts, forming threaded connection between the outer walls of the compensation nuts and the inner wire sections at the top ends of the sleeves while the inner walls of the compensation nuts are in threaded connection with the embedded bolts, filling the compensation nuts between the inner wire sections at the top ends of the sleeves and the embedded bolts, and forming a circle of welding seams to form reliable connection equivalent to welding; after the laminated clamping sleeve beam is reliably connected with the two sides and the top of the independent beam in a special design mode, the connection joint of the whole platform beam and the concrete independent beam can ensure reliable work under various possible complex stress models, has enough bending resistance, shearing resistance and torsion resistance bearing force, and can reliably transfer force and resist high-altitude overturning.

When the top is connected and installed, the plane positions of the four embedded long bolts at the bottom of the independent cantilever beam are required to be in a group within the allowable deviation range, so that effective measures are required to be taken to reduce the deviation of the embedded plane and the verticality on one hand, and measures are required to be taken to improve the fault tolerance, namely the deviation capability of the welded pipe on the superimposed clamping sleeve flat beam on the other hand.
