Definitions

  • the present invention relates to a prefabricated concrete step part.
  • steps of such a concrete staircase are usually formed by producing individual foundation parts from in-situ concrete or laying prefabricated foundation parts and then attaching tread plates to the foundation parts.
  • the DE 92 11 796 U1 reveals a concrete shaped block for the formation of stairs, walls and walls.
  • the concrete block consists of a lower plate and an upper plate, which are connected via a central bar that determines the distance between the plates, so that the shape of a double T-beam basically results.
  • a variety of such concrete blocks can be arranged in such a way that they form a staircase.
  • KR200410085Y1 shows a precast concrete step part with the features of the preamble of claim 1.
  • a general disadvantage of the prior art solutions is the high level of effort involved in laying the individual elements. If the tread plates are attached to the foundation parts on site, tensions often arise due to the different thermal expansion of the two elements. This causes the connection between the foundation and the tread plate to age, causing the tread plate to slowly loosen and begin to wobble.
  • the invention as characterized in the claims, is based on the object of providing a concrete staircase for outdoor use that is easy and inexpensive to install and at the same time has a long service life without noticeable aging due to environmental influences.
  • the present invention provides a prefabricated stair step concrete part having a foundation section and a step section, the foundation section being designed and set up for anchoring the prefabricated stair step concrete part in the subsurface.
  • the foundation section has a foundation section base area intended to rest on the ground and a foundation section lateral surface.
  • the step section has a step section cover surface provided as a tread surface, a step section base surface opposite the step section cover surface and a step section lateral surface.
  • the step section projects at least in a partial area of its step section lateral surface beyond the foundation section in a partial area of its foundation section lateral surface.
  • the prefabricated stair step concrete part has elongated reinforcing elements, with at least one of the elongated reinforcing elements arranged in the foundation section Foundation reinforcement section and a step reinforcement section arranged in the step section.
  • the vertical extent of the foundation section extending from the foundation section base area to the step section base area is at least 40 cm.
  • the prefabricated stair step concrete part according to the invention is a one-piece prefabricated concrete part.
  • the aging of the connection between the foundation and the tread plate, which is known from the prior art, due to different thermal expansion of the two elements cannot occur in the prefabricated concrete stair step part according to the invention.
  • the prefabricated stair step concrete part according to the invention has elongated reinforcing elements which extend into both the foundation section and the step section.
  • the two sections of the prefabricated stair step concrete part are statically connected to one another and can therefore be loaded with high weights.
  • a concrete staircase for outdoor use which is formed from a plurality of prefabricated concrete stair step parts according to the invention, is easy and inexpensive to install and at the same time has a high level of resistance to environmental influences.
  • All prefabricated stair step concrete parts can be produced individually in the precast factory for a specific external staircase. On site, only the subsoil is leveled with an appropriate gradient and provided with a usual layer of gravel or sand concrete. Subsequently, the individual prefabricated stair step concrete parts are inserted into the ground with their foundation sections in such a way that the step sections forming the stairs are aligned appropriately in the vertical and horizontal directions.
  • the cross section of the foundation section and/or the step section can be designed in almost any horizontal direction when installed.
  • a circular cross section of the foundation section and/or the step section is just as suitable as an oval cross section or a cross section composed of any number of flat sections.
  • a cross section composed of flat sections generally represents the envelope of a prism.
  • the present invention is described below using a prism with four sections, i.e. a cuboid, but it should be emphasized that each of the sections can be divided into a substantially arbitrary number of others can be divided into sections.
  • the horizontal cross section of such a foundation section and/or such a step section is then a polygon.
  • the foundation section and/or the step section has the shape of a cylinder, in particular a straight circular cylinder or an elliptical cylinder, or the shape of a prism, in particular a straight prism.
  • the foundation section has the shape of a conically tapering cylinder, i.e. a cone with a circular base, in particular a truncated cone, or a conically tapering elliptical cylinder, i.e. a cone with an elliptical base, or the shape of a conically tapering prism, i.e. a cone with a polygonal base or, in other words, a pyramid or a truncated pyramid.
  • a conically tapering foundation sections can prevent all steps located above the damaged step from also having to be removed. Because of the foundation section, which tapers conically starting from the step section in a direction away from the step section, the foundation section can be easily inserted into the ground even when adjacent prefabricated stair step concrete parts are installed.
  • the foundation section lateral surface has a plurality of flat foundation section lateral surfaces and/or the step section lateral surface has a plurality of flat step section lateral surfaces.
  • both the foundation section and the step section can basically have any shape.
  • a particularly simple production is possible if the respective lateral surface is constructed from several flat lateral surface sections. For example, if the foundation section has four partial foundation section surfaces, a cuboid results.

  • front and rear lateral surface mean the arrangement of the respective surface from the perspective of an observer who wants to climb a staircase made of prefabricated concrete steps according to the invention.
  • the above embodiment describes a prefabricated concrete stair step part for forming a conventional staircase with rectangular tread surfaces or with cuboid step sections.

  • the step section should not be oversized.
  • adequate dimensioning of the step section taking into account the loads that occur, is not a problem.
