Definitions

  • the invention relates to a prefabricated element for the construction of stairs and to the stairs obtained by assembling such elements.
  • these known elements each form both one of the elements of the supporting structure and one of the steps of this staircase.
  • these elements which have in plan a circular section are mainly formed of a plate which realizes the top of the step as well as a curved bottom having a vertical semi-elliptical section to offer a peripheral edge which supports the plate and to perform its bracing with respect to the plate of another element.
  • connecting fittings For their assembly, they use connecting fittings. These elements which, in plan, are offset from each other by about a half element each have holes including a central hole with a vertical axis and a whole series of holes with a horizontal axis distributed over a circle located at its periphery. A fitting is fixed, on the one hand, in the central hole of one element and on the periphery of the other element which, due to the offset, serves as a support or at least passes approximately under the center of the first element while that two other fittings are fixed on the periphery of the two elements to be assembled at the two points where, in plan, the circles of the peripheral holes intersect. These elements limit the possibilities of the shape of a step plate and require complex assembly operations.
  • FR-A-2,035,457 modular elements comprising a framework such as a cylindrical tube having at its ends two support pieces each provided with complementary assembly means distributed so that the assembly between elements can be done by exact superimposition of the circles of juxtaposed support pieces regardless of their mutual orientation.
  • the support pieces consist of washers welded to the inside of the frame tube slightly set back from the end faces.
  • the tube is pierced with an orifice.
  • the support pieces are also arranged so as to make an interlocking of one element with respect to the other, this to ensure continuity of the false upright.
  • each element of the aforementioned type in particular characterized in that it is in the planes of each of the ends of its framework that each element has its two support pieces, in that these support pieces come laterally projecting towards the outside of the frame and produces flanges parallel to each other and in that one of these flanges at least contributes to the production of a step plate.
  • a staircase 2 (2a, 2b) is formed from superimposed elements 3 (3a, 3b) and filled trays 4 in order to form the steps 5 of this staircase 2.
  • Element 3 (3 a , 3 b ) preferably has a circular horizontal section.
  • It comprises a framework 10 (10 a , 10 b ) and two end support pieces 6, 7 which are parallel to each other, the opposite faces 11, i2 of which have complementary means 14, 15 for assembly distributed over circles 13 of the same diameter. so that the elements 3 (3 a , 3 b ) are assembled together by exact superimposition of the circles 13 of the support pieces 6, ' 7 juxtaposed whatever their mutual orientation and whose faces 8, 9 are facing screws are therefore connected to each other by means of the framework 10 (10a, 10b ).
  • the complementary assembly means 14, 15 are formed by holes 21, passing right through at least one of the parts 6, 7 and receiving connecting members such as screws, bolts or studs.
  • each element has its two support parts, which parts project laterally projecting towards the outside of the framework and thus achieve flanges 6, 7 parallel to each other, at least one of which contributes to the production of a step plate.
  • the framework is of smaller external horizontal section than that not only of the flanges but also that that delimited by the aforementioned circles 13 on which the complementary means 14, 15 of the assembly means are advantageously distributed in the same way.
  • the frame can be constituted by several uprights 35 of small section so as to release the support flanges 6, 7 (FIG. 6), but preferably, it consists of a portion of cylinder 25 of diameter smaller than that of the says circle 13.
  • the framework is coaxial with said circle 13.
  • the cylinder 25 will preferably be formed by a tube and the support flanges 6, 7 will have openings 26 facing the internal cavity of the tubular section, which will then allow the passage of various pipes and / or cables.
  • the support flanges 6, 7 have at least their opposite faces 11, 12 which are preferably flat but, in an alternative embodiment (FIG. 6), they may be structures in sections such as simple hoops 17, 18 , located in parallel planes.
  • the complementary assembly means 14, 15 may include an open profile hoop 17 to come over that of the other hoop 18 to ensure rigorous positioning.
  • the complementary assembly means can in this case be produced in the form of flanges and / or collars.
  • the framework 10 (10 a , 10 b ) connecting between the supporting parts 6, 7 of the same element 3 (3 a 3 b ) has its fictitious axis 23 passing through the centers of the circles 13 which form, with respect to the plane of the flanges, an angle corresponding substantially to the slope given to the staircase.
  • one of the support flanges of the element is extended until acquiring a shape and dimensions making it suitable for directly forming the plate 4 of a step 5 of staircase.
  • a plate 4 is added either between the two juxtaposed support flanges, or it is applied above or below all of these two flanges - juxtaposed support flanges, which plate is then provided of parts cooperating with the flanges and / or the complementary means of assembling them so that, thanks to the assistance thus provided by the flanges, the plate is itself fixed.
  • the plate does not require any other element for its fixing than those already provided for assembling the elements together.
  • the flanges also contribute to the achievement of the step by better support of the plate 4 such as the plate of a step of a spiral staircase 2a by means a step or a frame 27 for supporting the platform of this step which has at least one pair of opposite members 32, 33 cooperating with complementary assembly means opposite the two support pieces 6, 7 of the same element 3 has such, for example, pins 32, 33 passing through bores 21 and therefore also using the same assembly means as those used for assembling the elements together.
  • this step or supporting framework will include at least two pairs of opposite members in order to exactly define its position relative to the element.
  • Some of the elements and in particular the extreme elements 31 of the staircase may carry a flange having a flap 29 perpendicular to the plane of the support flange in order to produce a stop taking up the horizontal forces of the staircase.
  • the staircase produced with these elements can advantageously (as shown in FIG. 7), alternately comprise elements whose fictitious axis of the framework is perpendicular to the plane of the flanges and elements whose fictitious axis is inclined relative to these planes flanges of an angle different from ninety degrees, which staircase can also turn from any step in one direction or the other to adapt to each particular case encountered in the configuration of accesses to the different landings of 'a building to be fitted with said staircase.
