Abstract

The invention discloses a steel ladder cage installation structure and installation method. The steel ladder cage installation structure comprises two steel boards, a piece of shape steel and a plurality of fastening assemblies. The two steel boards are fixedly arranged on two wings on the side, opposite to the inlet side, of the first cage body of a steel ladder cage. The two steel boards are correspondingly provided with multiple rows of first connecting holes distributed at intervals in the height direction of the steel ladder cage. The shape steel is provided with a plurality of second connecting holes in the length direction of the shape steel, the second connecting holes correspond to the first connecting holes, in the same rows with the second connecting holes, in the two steel boards in a one-to-one mode in position and size. The shape steel is arranged horizontally, the two ends of the shape steel are fixedly arranged on a support or a slab. By means of the fastening assemblies, the first connecting holes and the second connecting holes in the same rows enable the two steel boards to be detachably and fixedly connected with the shape steel. The steel ladder cage installation structure solves the technical problems that in the prior art, the steel ladder cage is inconvenient to disassemble and assemble and is poor in operation safety, and has the advantages that the steel ladder cage is safe to install and use and convenient to disassemble and assemble.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a steel ladder cage installation structure and an installation method. Background technique [0002] Most of the pedestrian passages during the construction of deep foundation pits in the existing basement have adopted simple stairs built by steel pipes, referred to as steel pipe simple stairs. Since the steel pipe simple staircase has no specific model and erection specifications, its safety quality is worrying. Moreover, the required height of the steel pipe simple staircase changes with the depth of the excavation of the foundation pit, and the position of the steel pipe simple staircase on the horizontal plane needs to be changed frequently. Demolition and new construction waste a lot of labor and lengthen the construction period. [0003] At present, the emergence of steel ladder cages has significantly improved the above situation. But on the one hand, th...
