Further, the bottom of the upper landing leg is higher than the bottom of the lower landing leg, so that the upper landing leg and the lower landing leg can be placed on platforms with different elevations at two ends of the bench plate.
Further, the upper surface of the lower platform is provided with a limiting rod, and when the upper platform and the lower platform are unfolded in parallel, the free end of the limiting rod is abutted against the middle supporting leg to play a role of rotation limiting.
Further, a diagonal bracing is arranged between the lower platform and the lower supporting leg, so that the stabilizing effect is achieved.
Further, the side of the upper supporting leg is provided with a crawling ladder, and constructors can reach the upper platform through the crawling ladder to construct.
Furthermore, the surface of the upper platform or/and the lower platform is provided with the protective railing, so that a safer construction environment is provided for operators.
The beneficial effects of the utility model are as follows: the protective rail is hoisted to the assembled stair, one end of the lower platform is rotationally connected to the joint of the middle supporting leg and the supporting rod, the lower platform is automatically folded due to self gravity during hoisting, the occupied area is reduced, dangers caused by hooking reinforcing steel bars and templates are avoided, after installation is completed, the free end of the limiting rod is abutted to the lower part of the middle supporting leg, the lower platform and the supporting rod form an integral cross beam, the load transmitted from the upper part is born, and the safety coefficient is high during construction; the upper supporting leg and the lower supporting leg can be firmly supported on the stair rest platform and the floor platform, and can provide safer working environment for upper layer reinforcing steel bar binding and template supporting personnel after the installation is completed. The utility model has simple structure, convenient disassembly and assembly, tight protection and no influence on the normal passage of stairs during the installation, disassembly and use.
