The lower rail I-shaped connecting piece is temporarily fixed after being embedded, and is fixed after the verticality of the pull rod is adjusted;
installing a stainless steel pull rod:
the pull rod penetrates through a bolt hole in the middle of the I-shaped connecting piece to be connected with the I-shaped connecting piece and is screwed and fixed by a locknut; the step of the stainless steel pull rod at the lower end is consistent with that of the upper end part, the tightness of the pull rod is adjusted by using a turn buckle after the lower end pull rod is fixed, the verticality of the pull rod is checked before fastening, and the clearance parts of the special steel rails on the floor ground are covered one by using a dustproof cover plate after the fixing is finished;
step connecting piece installation:
firstly, firmly locking a base and a gland of a pull rod connecting lock on a solid pull rod of a stainless steel pull rod through four hexagon socket head cap screws according to the marked position of the pull rod connecting lock, locking the base and the gland of the pull rod connecting lock on the hollow pull rod after a reserved line on the pull rod penetrates through a vertical goose egg hole of the base, and connecting and fixing a connecting claw side plate and the pull rod connecting lock base by using a stainless steel bolt; the U-shaped hoof clamp penetrates through the hollow pull rod and is fixedly connected with the K-shaped stainless steel spider side plate through the hexagon socket head cap fastening screw;
step connection installation:
before the step installation, the overlap joint is installed in the overlap joint installation holes at the two ends of the toughened laminated glass step respectively, and the installation progress of the overlap joint is synchronous with that of the step;
step installation:
before the step installation, the scaffold is firstly dismantled according to the special scheme of the scaffold; the steps are sequentially installed step by step from bottom to top, the overlap joint of the step with the installed overlap joint is embedded into the overlap joint claw, a fastener is sleeved and temporarily fixed, the levelness of the step is measured by a horizontal guiding rule, the periphery of the step is smooth by adjusting an adjusting nut of a ball head connecting screw rod of the overlap joint, the fastener is fastened, rechecking is carried out once each step is installed, and error accumulation is prevented;
installing handrails:
the handrail pull rod connecting piece is positioned according to the height required by the specification and is fixed on two adjacent solid pull rods of two adjacent steps, then the stainless steel handrail adapter piece is fixed on the connecting piece, the handrail surface pipe is temporarily fixed above the connecting piece, and the hexagon screws in the handrail connecting piece are fastened after unified alignment.
