Definitions

  • the invention relates to a self-supporting staircase made up of individual steps along a definable, polygon-like staircase layout are interconnectable.
  • Stairs cast from concrete not only benefit from the proven, in part adjustable properties of this material, but can also be used with the adapted to the respective requirements are made if for a appropriate, but expensive formwork is provided.
  • Let concrete stairs can also be made up of prefabricated stages, but in general only for straight flights of stairs.
  • Steps pivotable relative to one another about a vertical joint axis are shown in known various embodiments.
  • EP 0 134 572 A2 shows this Prefabricated support elements for a step to be retrofitted, whereby the support elements upstanding connecting pins, which in a Engage the recess in the next higher support element with play.
  • the The spigot is poured into the recesses.
  • the disadvantage is before all that the individual support elements are connected to separate mounting supports Need to become.
  • DE 1 683 297 A is for each stage a metallic support is provided, which on the one hand projects downward Pin and on the other hand has a pipe socket on the top that the Pivots the next higher level.
  • the carriers of the gradual Assembled stairs serve as reinforcement for step plates that can be retrofitted have to be poured elaborately.
  • the invention is therefore based on the object of a self-supporting staircase type described so that they have the advantages of a concrete cast stairs with it, without a modular system Composing the flight of stairs from individual steps along one given, even odd course.
  • the invention solves the problem in that the individual stages in each case consisting of two parts that can be pivoted against each other around a vertical axis exist, which on the opposite to each other with respect to the pivot axis Staggered sides with openings Have pads for the following stages, and a common Lost formwork enclosing a cavity with a cover coverable, upper filling opening for a concrete filling, the individual in the use position of the stairs Steps through to the next steps in the connecting areas provided through openings.
  • the stairs joined steps forming a continuous hollow body can be completely filled with concrete from the top step the individual steps open the upper filling openings through which the staircase runs in sections can be filled with concrete. These filling openings have to go through Lids can be closed to prevent leakage of the not yet set Prevent concrete when filling the subsequent steps.
  • the steps with concrete and setting the concrete After pouring the steps with concrete and setting the concrete, the are of course reinforced according to the respective requirements can, a flight of stairs with a continuous concrete core is obtained without an elaborate formwork to be adjusted to the respective course of the stairs to have to provide.
  • each stage Because of the formation of each stage as a section of a lost one Formwork for a concrete core passing through the stairs is a concrete-tight one Connection on the one hand between the individual stages and on the other hand between the two parts of each stage. While such concrete-tight connection between the individual stages because of their level Pads does not pose any difficulties when connecting of the two parts of each stage to take into account their mutual pivotability. For this reason, it is recommended to use one of the two parts of each Step with a circular cylindrical connecting surface coaxial to the swivel axis to train for the other part. This circular cylindrical pad offers matching connection conditions for everyone in a simple manner mutual swivel positions of the stage parts.
  • the cantilevered staircase shown is according to the invention from individual steps 1 constructed, each consisting of two parts 2 and 3, which are against each other are arranged pivotably about a vertical axis.
  • This pivot axis is in the embodiment by a formed on part 2, circular cylindrical Wall section 4 is formed, along the circumference of which part 3 can be pivoted, as can be seen in particular from FIG. 2.
  • the part 3 lies with oppositely curved edge webs 5 on the by Wall section 4 formed pad 6, the mutual Guide the two parts 2, 3 of each stage 1 by extending in the circumferential direction Elongated holes can be made.
  • the parts can be obtained in any swivel position of parts 2 and 3 3 continuous in the circumferential direction over the connection surface 6 of part 2
  • Levels 1 thus form hollow bodies.
  • the concrete that is poured in fills these hollow bodies continuously because the individual Stages 1 yes via the passage openings 9 in the connection surfaces 7 and 8 communicate with each other.
  • the filling openings 11 are after filling to close the respective stages 1 with the lids 13 to prevent leakage of the concrete when filling the subsequent upper stages 1 from the To prevent filling openings 11 of the lower stages 1.
  • FIG. 3 Around a flight of stairs, which is shown in FIG. 3 in plan Polygon represents, to be able to manufacture from individual stages 1, the Parts 2 and 3 of the individual stages 1 on the one hand against each other according to the desired course of the stairs swiveled and in the mutual swivel position fixed and on the other hand via the connection surfaces 7 and 8 with the upwards and connected to the following stages 1.
  • the bottom passage opening 9 of the entrance step and the upper passage opening 9 of the exit step suitable covers are to be closed if there are none on the stairs Stair landings 15 are connected.
  • These stair landings 15 can in a manner consistent with levels 1 of two pivotable against each other Parts 2a and 3a are formed in order to create a platform area To allow adaptation of the flight of stairs to a given course.
  • stair landings 15 and steps 1 The only difference between such stair landings 15 and steps 1 consists in the fact that the stair landings 15 do not form a riser like this 1 can be seen. Of course, such stair landings also arranged at any point within the stairs become. After connecting the individual stages 1, their height offset determines the slope of the stairs and therefore also to set a predetermined one Incline must be chosen accordingly, and if necessary the intended Stair pedestals 15 can be poured out in stages 1 or the stair landings 15 continuing with concrete from bottom to top be started. After the concrete core has set, as required can be reinforced, its properties are largely of its own Preserve the concrete core of certain stairs, its steps and risers with different editions can be provided.
  • Parts 2 and 3 can be made of metal, plastic, building materials u. Like. exist and receive different shapes, if only the mutual swivel adjustment is maintained.
