Definitions

  • the invention relates to quarter-turn or half-turn stairs made of reinforced concrete connected to side walls or supports are, which preferably consist of reinforced concrete.
  • Quarter-turn or half-turn staircases made of reinforced concrete are usually poured into in-situ concrete or prefabricated as prefabricated concrete parts by manufacturing companies and assembled on site at the construction site.
  • the production of the spiral stairs made of reinforced concrete on site requires formwork including the attachment of connecting reinforcement and support lugs.
  • the preparation of the stairs from reinforced concrete on site has the considerable disadvantage that extensive preparatory measures are necessary on the construction site and this results in a high expenditure of time.
  • the prefabricated stairs have to be installed in a time-consuming manner, whereby assembly locks are required. These measures each require a high level of skill during installation, since aligning the stairs, this is particularly true for spiral stairs, places high demands on those who work on the building site. Assembly errors are not uncommon. Due to the complicated installation, the assembly takes a lot of time.
  • the invention has as its object the assembly effort to a minimum by assembling the coiled Reinforced concrete stairs quickly without aligning the spiral staircase takes place in the traditional sense and at the same time avoid assembly errors.
  • the side walls (2) or optional supports (3) are used preferably made of reinforced concrete.
  • the spiral connection of reinforced concrete stairs (1) with the reinforced concrete walls (2) or supports (3) can be carried out in a technological production stage as part of the prefabrication of the reinforced concrete stairs.
  • the construction of the construction according to the invention from a spiral staircase made of reinforced concrete (1) and reinforced concrete walls (2) or supports (3) is carried out in one Casting "carried out, the connection of the parts in a conventional manner, for example by means of concrete reinforcement, which causes a sufficiently firm connection of the parts to one another.
  • the stairs are optionally made Provide reinforced concrete (1) with one, two or three side walls (2).
  • the side walls (2) or supports (3) are preferably formed at floor level. Instead of the side walls (2) there is also the option of connecting the spiral staircase made of reinforced concrete (1) with supports (3) made of reinforced concrete, the connection also being made in a single manufacturing document when using reinforced concrete.
  • the prefabricated spiral stairs made of reinforced concrete offer due to their already fixed in the manufacturing process Formation on the floor-high side walls the possibility Stairs both individually on the floor or on false ceilings to be able to set up.
  • the correct installation dimension and the angle of attack of the stairs are fully fixed by the side walls, so that their alignment is reduced to a minimum during installation.
  • the stairs made of reinforced concrete with side walls prevent assembly errors since the alignment only has to be carried out by means of a vertical and horizontal part of the reinforced concrete walls.
  • Stairwells composed in a manner that consists in the fact that because of the smaller contact areas between the Conventionally connected stairs made of reinforced concrete with side walls and the surrounding walls and Ceiling is connected to a low sound transmission and so that an improvement in sound insulation is made possible. As a rule, it can even be assumed that during assembly there are no points of contact with walls.
  • the side walls can already be in the Prefabrication or on site with a sound absorbing Provide layer of conventional suitable materials become.
  • FIG. 1 shows how a quarter-turn staircase made of reinforced concrete (1) with two precast concrete side files (2) is provided. It becomes clear how on simple way of assembling the prefabricated coiled Reinforced concrete stairs (1) with side walls (2) can take place in part A, for example on the base is set up, while Part B on the floor above stands on the ceiling. Because of the straight Areas of the reinforced concrete side walls (2) is between part A and Part B allows easy alignment during assembly.
  • Figure 2 shows the spiral staircase in plan view Reinforced concrete (1) with two reinforced concrete side walls (2), wherein from the figure Figure 3 (side view above), Figure 4 (Side view center) and Figure 5 (side view bottom) clearly it becomes apparent how a close and stable connection between the concrete side walls (2) and the spiral staircase made of reinforced concrete (1) can be reached.
  • Fig. 4 (middle side view) it can be seen that in use of two reinforced concrete side walls (2), the spiral Reinforced concrete stairs (1) are self-supporting on one side. In an example, there is a span of about 2 m bridged.
  • FIG shown that depending on the chosen application, the on the planning side or on the construction site, supports (3) Reinforced concrete or steel are used.
  • the Connection of the spiral staircase made of reinforced concrete (1) with the supports (3) made of reinforced concrete is sufficiently strong and ensures the same advantages of the invention Solution as achieved with the reinforced concrete side walls (2) becomes.
  • the use of supports (3) advantageously allows realize other applications.
