Definitions

  • the invention relates to a self-supporting elementary staircase, preferably used as an external staircase, as it is used both as an inspection staircase in industrial plants and as a fire escape staircase in hotels or other large buildings, and as an external staircase in residential construction.
  • the object of the invention is to provide a staircase for the above-mentioned applications, which is economical to manufacture and assemble, low in material consumption and can be used practically for any staircase run without a special construction.
  • a tubular steel construction which consists of U-shaped connecting brackets, handrail parts attached to the upper ends of the connecting brackets and treads inserted at the lower ends of the connecting brackets by clamping connections, the connecting brackets at the upper ends by the handrail parts and in the lower Beich connected by the steps.
  • Fig. 1 shows the typical flight of stairs of a spiral staircase. 4 components are sufficient to manufacture this stair run: step, connecting bracket, outer and inner handrail part.
  • Fig. 4 shows the perspective view of two step elements to be assembled.
  • Fig. 5 shows the step for straight running and Fig. 6 shows the step for radii.
  • Fig. 7 shows an enlarged view of the handrail parts attached to the upper ends of the connecting brackets, and their attachment.
  • the central component of the staircase is the U-shaped connecting bracket (1) made of tubular steel.
  • the connecting brackets are connected to each other at the upper ends by the handrail parts (2) and in the lower area by the steps (3).
  • the handrail parts (2) consist of a steel tube bent according to the stair inclination with a connecting sleeve (5) welded crosswise on one side.
  • the connecting bracket (1) is inserted into this connecting sleeve from below and the free end of the following handrail part from above.
  • the steps (3) consist of a flat steel frame, which is designed as a pipe clamp at all four corners. These pipe clamps reach into the lower area of two pairs of connecting brackets and ensure a particularly rigid connection by tightening the 3 or 4 pipe clamp screws.
  • two steps are used as the step.
  • the straight step (Fig. 5) for the straight execution of the staircase and the radius step (Fig. 6) for the curve of the staircase.
  • the frame construction of the steps can be filled with grating, perforated plate, teardrop plate, stone, wood and plastic coverings.
  • the symmetry of the radius step makes it possible to use it for both the right-hand arch and the left-hand arch of the flight of stairs.
  • a sheet metal (6) welded to the handrail part (2) serves to accommodate the railing rods (4) which are fastened to the step in the lower area. This option is only one of many. Complete linings made of perforated sheet or similar are also possible. conceivable.
  • the stairs can be assembled very quickly without reworking. Special surface treatments of the finished tubular steel u. Step elements can thus be made before the stairs are assembled, since they are completely finished individual parts.
