Definitions

  • the present invention relates to a prefabricated concrete staircase, straight or quarter turn type.
  • Prefabricated concrete staircases consisting essentially of modular elements, are commonly used to the extent that they are easily and quickly put in place, and inexpensive.
  • the document EP 0 126 681 describes a prefabricated concrete staircase consisting of at least one silt and previously manufactured staircase elements.
  • the silt is provided with transverse notches intended to anchor the walking elements.
  • the latter consist of a horizontal wall and a vertical wall thus forming the step and the upper riser.
  • the document FR 2 801 619 describes another type of prefabricated concrete staircase.
  • the walking elements are monobloc and include a step, a riser and two silts. The assembly of these monoblocks constitutes the staircase.
  • the document FR 2 801 620 describes a straight prefabricated concrete staircase with no silt.
  • the implementation of this staircase requires the installation of a bastaing according to the angle of inclination of the staircase and on which the prefabricated step elements are placed one after the other.
  • the walking elements ensure both the support and the cohesion of the staircase. When several of them are positioned on the bastaing, they have below the tread a structure defining a linear and continuous cavity.
  • a reinforcement is introduced into the linear cavity located below the tread of the walking elements. This cavity is then filled with concrete.
  • the document JP 11050625 also describes a straight concrete staircase comprising a rack.
  • the rack comprises two lateral parts interconnected by a lower part. It is actually made of several elements, each element extending unitarily along the entire length (or height) of the staircase.
  • the document DE 1,039,212 describes a straight staircase made of concrete, the rack of which consists of elements extending along the entire length of the staircase, as in the document JP 11050625 .
  • the Applicant has developed a prefabricated concrete staircase that does not require the prior installation of a silt and may be of straight or quarter-turn type.
  • the staircase according to the present invention is manuportable, and has the advantage of being able to be straight or quarter turn. Its realization makes it possible to overcome the problems related to the weight, because of the modular character of the elements which constitute it.
  • the present invention relates to a prefabricated concrete staircase, consisting of at least one rack.
  • the latter is directed according to the angle of inclination of the staircase; it provides support for the walking elements.
  • At least one step element comprising a step and a riser, is arranged on the rack.
  • the step element and the rack and form a linear cavity and continuous to receive a reinforcing mechanical reinforcement, and then to be filled with concrete.
  • the staircase according to the invention is characterized in that the rack is in the form of individualized elements with respect to the direction of the stairway defined by the slope, said elements each being constituted by two lateral parts interconnected by a lower part. At least a lateral portion of each of these individual elements forming the rack is shaped to receive a step and a riser.
  • the staircase according to the present invention has the advantage of being able to be straight or quarter turn.
  • the support beam of the steps is constituted by at least two racks
  • the latter are images of one another and allow the support of walking.
  • the two racks are symmetrical to one another with respect to a vertical plane.
  • the staircase includes a reinforcement placed in each rack before the latter is filled with concrete.
  • concrete is added element of walking after walking element. Indeed, the concrete is poured into the rack and the step element is then sealed over it.
  • the On / rack connection is provided by two steels in loop coming from the lower face of the step. These steels also make it possible to ensure the handling of said steps.
  • the individual elements of the rotating rack have three side portions and are not reinforced by reinforcement.
  • each individualized element forming the rack of the staircase according to the invention comprises an anchor foot intended to be housed in the corresponding female part of the lower part of the step.
  • This self-locking device thus makes it possible to stabilize the step element.
  • the step element comprises a step and an upper riser, ensuring the formwork, said riser extending over the entire length of the step, or limitatively to the plumb of the House warming party.
  • the individualized elements forming the rack can be single or double. In other words, they can receive one or two walking elements. In doing so, it is possible to make stairs with even or odd steps.
  • each of the individualized elements is advantageously constituted of a single unitary part formed by two lateral parts interconnected by a lower part in the case of a straight staircase.
  • the introduction of a reinforcement or reinforcement provides mechanical support to the structure.
  • the laying of the steps and the pouring of the concrete into the rack as the assembly progresses makes it possible to make the rack and the staircase without heavy handling means.
  • the step with its riser constitutes the shuttering element with the individualized element of the rack resting on the bastaing.
  • step element does not have a higher riser
  • additional formwork is necessary in order to contain the concrete and ensure the installation of the upper step.
  • one of the lateral parts in this case the internal lateral part (10) is beveled (12), that is to say that its thickness is reduced in the direction of the bottom. In doing so, one optimizes the mechanical maintenance with the concrete, once this one cast, the beveled form preventing any risk of separation of the concrete.
  • the figure 7 illustrates the front (A), section (B) and top (C) views of an individual rack member providing the turn (6) for the realization of a quarter-turn staircase.
  • FIG 8 a cross-sectional view of a step associated with an individualized rack member according to the invention, in which the rack is constituted by two elements contiguous to one another, like the figures 1 , 3 and 4 .
  • a bastaing (16) is put in place and supported, prior to pouring the concrete.
  • This bastaing is removed after sufficient hardening of the concrete set up in the individualized components of the rack. It can, however, be maintained during the hardening phase of the concrete, to allow the use of the staircase in progress.
  • the modular elements constituting the rack are made by molding concrete.
