Definitions

  • the invention relates to a staircase for a ground-mounted installation in an embankment.
  • Stairs in the outdoor area are either made of prefabricated stone steps made of concrete, natural or artificial stone, which are installed superimposed.
  • Stairs made of prefabricated step material usually have no cheeks, which makes it difficult to create a staircase in embankment areas, as the slope line can not be precisely defined.
  • the staircase designed as a metal structure consists of two stair stringers and several risers, which are attached to the stair stringers by means of lock plates.
  • the risers have at their ends facing the cheeks guide pins and locking hooks, which are associated with corresponding breakthroughs in the cheeks.
  • the locking plates each have a gap-shaped recess and are to be hammered with a hammer behind the on the outside of each stair string protruding locking hook and frictionally engaged.
  • the present invention has for its object to provide a cost-effective stair scaffold, which easily allows the production of an earth-bound, high-quality embankment stairs, in which the step appearance is formed by filling the space between successive risers, the staircase to the local conditions should be easy to customize.
  • the staircase according to the invention has two stringers and at least one riser releasably connectable to the stringers.
  • the stair stringers are each formed from a plurality of cheek segments, wherein the riser is provided with extending transversely to its front surface connecting tabs on each of which two successive cheek segments are releasably fastened.
  • the attachment is preferably carried out by means of screw, so that the mechanical stress at the joints in contrast to the closure hook connection according to the known from DE 203 18 491 U1 staircase is comparatively low. Accordingly, the staircase according to the invention can be produced in particular from relatively inexpensive galvanized sheet steel.
  • the staircase according to the invention is designed as a modular system and can be industrially prefabricated in large numbers.
  • the risers are designed uniformly. This preferably also applies to the cheek segments. As a result, the production costs can be significantly reduced and the quality assurance can be simplified.
  • the cheek segments are preferably formed substantially rectangular and plate-shaped.
  • the cheek segments can also comprise two or three different types of cheek segments, namely a uniform, substantially rectangular base type, of which any number can be lined up in succession, and lower cheek end segments and / or upper cheek end segments which each have an angle relative to the lower edges of the cheek segments of the basic type, in particular substantially horizontally extending support edges, and which serve to produce a staircase at the lowest step or a staircase exit at the uppermost step.
  • the embankment scaffolding according to the invention can be easily adapted to the respective local circumstances.
  • the individual components of the staircase according to the invention are relatively easy and space-saving storage and transportable. They are particularly uncomplicated in their handling and assembly, so that the assembly time compared to conventional embankment stairs is significantly reduced.
  • the connecting straps for releasably securing the risers to the cheek segments are preferably formed integrally on the respective riser.
  • they may consist of sections folded over a longitudinal plane of the riser.
  • the cheek segments and the connecting straps of the respective riser have mutually associated connection holes, wherein the connecting holes of the connecting straps and / or the connecting holes of the cheek segments are preferably designed as square holes.
  • the releasable connection of the riser with the successive cheek segments can thus be done using square head screws, which can be tightened due to the positive connection without manual holding the screw head and allow a substantially smooth design of the stair string outside due to their round head.
  • connection holes but can alternatively be formed as round holes, in particular as slots. Also other screws, especially hexagon screws can be used.
  • a further advantageous embodiment of the staircase according to the invention is that the riser has a profiled in its longitudinal direction upper edge.
  • the profiling has an anti-slip effect.
  • the riser thus has a safety leading edge.
  • the riser top edge can be designed to be wavy or serrated, for example.
  • the riser has an upper fold and a lower fold in its longitudinal direction, wherein the upper fold defines an upper riser section and a downwardly adjoining, stepped out to the step outlet riser section, while the lower fold a lower riser section defined, which is folded towards the staircase.
  • the lower fold is preferably approximately equal to the lower edges of the cheek segments.
  • An advantageous embodiment of the escarpment embankment according to the invention further consists in that at least some of the cheek segments have fastening elements and / or mounting holes for attaching a stair railing.
  • the fasteners may be configured in particular as a plug connection.
  • the staircase according to the invention serves to produce a slope embankment, which is sometimes referred to as a landscape staircase.

  • the bending angle here is about 75 degrees.
  • the width of the step outlet bevelled or inclined riser section 11 is about 18 cm, while the width of the lower riser section 15 is only about 2 to 3 cm.
  • the upper edge 16 of the respective riser 2 is preferably profiled in its longitudinal direction slip-resistant.
  • the upper edge 16 can be profiled, for example, uniformly wavy or jagged, with the height of the corrugations or tines (not shown) being in the range of 0.2 to 1 cm and their pitch in the range of 0.5 to 3 cm.
  • the upper edge 16 of the riser 2 is wider by a there additional relatively narrow portion 23 is provided, which is preferably folded substantially parallel to the step appearance in the direction of the staircase or the next higher riser 2 (see Figures 8 and 9).
