Definitions

  • the present invention relates to staircases and more particularly to prefabricated straight staircases.
  • Prefabricated concrete staircases generally make it possible to save time both at the manufacturing level and at the installation of the staircase on the site.
  • the manufacturing gains are of course a function of the quantity. stairs to produce, they are also a function of the simplicity and the number of elements that make up the staircase.
  • the invention aims to produce a staircase adapted both to an industrialization of manufacturing and to a wide field of application because of its simplicity.
  • This type of staircase according to the invention, is suitable as an entrance staircase for a pavilion, cellar staircase, interior building staircase; it is easy to install without handling equipment due to its reduced weight.
  • the elements of steps which compose it allow a great. flexibility of use going from the steep staircase to the more elongated staircase, each step remaining perfectly horizontal whatever the slope of the staircase.
  • the staircase consists of at least one stringer and steps; the or each stringer has transverse notches for anchoring prefabricated step elements.
  • the prefabricated element consists of a molded step with a perpendicular wall forming on the one hand the riser and on the other hand an anchoring foot positioned in the notch of the stringer.
  • Each notch of the stringer has a V-shaped section rounded at the tip. This rounding has a radius substantially equal to half the thickness of the anchoring foot so as to correspond to the rounding of said anchoring foot thus allowing pivoting of the anchoring foot, and therefore of the element of walking, in the corresponding notch.
  • the appended drawing illustrates, by way of example, an embodiment of a staircase in accordance with the present invention.
  • the staircase as shown is arranged between a ground level 1 and the landing of an upper level 2.
  • the or each stringer 3 stairs are precast in concrete in the form of a beam; it is placed and sealed in housings 4 and 5 prepared at level 1 and at level 2. These housings are adapted to the ends of the stringers, which ends are either perpendicular to the longitudinal axis of the stringers, or horizontal as shown on the figure.
  • each stringer 3 is anchored at its lower part on level 1 and it is fixed at level 2 by means of an assembly device known by the name of HALFEN rail; a rail is embedded in the upper part of the stringer at the time of molding and its protruding part in a dovetail, fits into a complementary shape 5 embedded under level 2, so that the stringer can be put in place by a or two people and its sealing is carried out at the bottom, at the level of the housing 4, at the same time as the installation of the first prefabricated step element 6.
  • This first element 6 serves as a reference for the concreting of level 1.
  • the step 7 being embedded in this concreting.
  • the prefabricated step element 6 consists of the step 7 proper and a vertical wall 8 serving on the one hand as riser 9 and anchor foot 10 on the other hand, which anchor foot protrudes below of the step of a height substantially equal to the thickness of said step.
  • the step 7 and the wall 8 are in one piece; they are made of concrete, obtained by molding and reinforced as appropriate.
  • the anchoring foot 10 is disposed in the first ridge 11 at the bottom of the stringer and rests on the horizontal bottom thereof.
  • the notches 11 are arranged transversely and are regularly spaced on the upper face of the or each stringer 3; they are obtained by molding and have a V-shaped section with a rounding at the point.
  • This rounding which corresponds to a portion of the cylinder casing to which the sides of the Vee forming the notch 11 are connected, receives the anchoring foot 10 of the step element 6.
  • the radius of the rounding is obviously equal to half the thickness of the anchor foot 10.
  • Said anchor foot has its rounded lower end also to match the shape of the bottom of the notch 11.
  • the opening of the V of the notch corresponds to the angle formed by the wall 8 in its extreme positions of inclination.
  • the height obtained between said steps 7 may vary while remaining uniform from one step to another, by means of a heel 12 disposed under each step.
  • This heel 12 has an inclined face 13 in contact with the rear upper edge 14 of the riser 9.
  • the heel 12 is obtained directly by molding, it extends over the entire lower part of the step.
  • the inclined face 13 of the heel is substantially planar, and it lies in a plane which is perpendicular to the average position of the or each stringer 3, that is to say between its maximum inclination and its minimum inclination.
  • the maximum inclination of the stringer is obtained when the edge 14 is located at the lower end of the inclined face 13 of the heel 12
  • the space 15 between the underside of the step 7 and the upper part of the riser 9 is filled with concrete to strengthen the base of the step on the riser.
  • the edge 14 of the riser 9 can, on the other hand, be slightly rounded to avoid excessive fragility.
  • the staircase is produced by successively mounting the tread elements 6 in superposition, by pressing the anchoring feet of said elements in the notches 11 regularly spaced on the or each stringer.
  • the last upper notch 11 receives the upper prefabricated element 6 on which the riser will come to bear the landing step 16 consisting of a slab sealed on the landing of level 2 in the extension of the yoke 17; the landing step can also be carried out directly, by a formwork on the last riser, when the screed 17 of level 2 is poured.
  • the invention allows more or less steep stairs to be produced using the same prefabricated step elements in which the stair nosings are more or less pronounced.
  • the width of the prefabricated element is variable depending on the width of the staircase to be made and this element can be supported by a wide central stringer or by several strings each having indentations for positioning the anchoring feet.
  • the invention can be applied to all types of stairs.
