The ladder comprises an upper ladder beam and a lower ladder beam, wherein the upper ladder beam and the lower ladder beam are arranged in parallel, and channel steel is adopted for the upper ladder beam and the lower ladder beam.
The connecting piece is the L type, and the medial surface that goes up the ladder roof beam is fixed in to the one end of connecting piece vertical plane adopts last ladder roof beam connecting bolt, and the other end that the connecting piece vertical plane adopts lower ladder roof beam connecting bolt to be fixed in the medial surface of lower ladder roof beam.
The step plate is positioned on the transverse plane of the two oppositely arranged connecting pieces, and the two ends of the step plate are fixedly connected with the transverse plane below the step plate through the step plate connecting bolts.
The tread plate is a 4.5mm thick pattern steel plate.
The utility model has the advantages that:
the steel ladder of the utility model is a novel steel ladder, the connection of the step plate and the ladder beam of the steel ladder changes the traditional welding method, and the steel ladder is assembled and disassembled, and the installation height can be adjusted in a certain range; the steel ladder can be assembled and assembled, has adjustable height and can be disassembled, and the steel ladder is convenient, rapid and simple to assemble and disassemble, and saves time and labor; the comprehensive cost is low, the product can be recycled for multiple use, and the product has the characteristics of safety, greenness, beauty, practicability, energy conservation and environmental protection; along with the popularization of green buildings and the implementation of standardized construction sites, the assembled adjustable novel steel ladder has a very wide application prospect.
Through divide into two parts (going up the ladder roof beam and the lower ladder roof beam) that upper and lower parallel respectively with left and right ladder roof beam, go up the ladder roof beam and pass through the connecting piece with going up ladder roof beam connecting bolt, lower ladder roof beam connecting bolt fixed, utilize the relative slip between going up the ladder roof beam and the lower ladder roof beam, reach the requirement that mounting height is adjustable, simultaneously easy to assemble dismantlement. The cross surface of the connecting piece of the left ladder beam and the right ladder beam is fixed with the step plate by the step plate connecting bolt, so that the assembly and the disassembly are convenient, and the requirement of an assembly type is met. The assembly type adjustable steel ladder is installed on a construction site, is quick and simple, saves time and labor, and can be adjusted in installation height; the assembly type is detachable, can be recycled for multiple times, and has low comprehensive cost, energy conservation and environmental protection; the stair installing structure is particularly suitable for the positions where the stairs need to be installed and the passage with a certain height difference on the building construction site.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings;
as shown in fig. 1, an assembled adjustable steel ladder comprises a pair of ladder beams, wherein each ladder beam is divided into an upper part and a lower part which are parallel, and the two parts are fixed from top to bottom through connecting pieces which are arranged in parallel; the connecting pieces 3 of the two ladder beams are symmetrically arranged. The upper ladder beam and the lower ladder beam are arranged in parallel, namely an upper ladder beam 1 and a lower ladder beam 2, the upper ladder beam and the lower ladder beam are made of 10 channel steel, the upper ladder beam 1 and the lower ladder beam 2 are arranged in parallel up and down, a L40X 4 angle steel is adopted as a connecting piece, ladder beam connecting bolt holes phi 17.5 are formed in the upper end and the lower end of a vertical surface of the connecting piece, one end of the vertical surface of the connecting piece 3 is fixed on the inner side surface of the upper ladder beam 1 through an upper ladder beam connecting bolt 7, and the other end of the vertical surface of the connecting piece 3 is fixed on the inner side surface of the lower ladder beam 2 parallel to the upper ladder beam 1 through a lower ladder beam connecting bolt 4; and a step plate 5 is fixed on the transverse plane of each group of the two oppositely arranged connecting pieces 3 between the left and right ladder beams through a step plate connecting bolt 6 to form an assembled adjustable steel ladder.
