Definitions

  • the invention relates to a straight staircase with two stringers, capable of being prefabricated in the factory and made up of standard elements whatever the height of the drop.
  • Stairs thus conceived are therefore unsuitable for satisfying a total standardization such that the same staircase can be used for a gentle ascent (for example inclination at 60 ° with respect to the horizontal) or for an abrupt ascent of the sucker's ladder (for example inclination at 30 ° to the horizontal).
  • the design of a prefabricated staircase implies that the constituent elements are able to take between them various relative positions controlled by the inclination of the stringers and this, reducing the machining work to a minimum.
  • the staircase intends to provide a satisfactory solution to this imperative, certain data of which are contradictory to each other, and this, for inclinations extending at least from 30 to 60 ° relative to the horizontal.
  • This staircase is designed in such a way that the bolts (two per step) join to the stringer both the steps and the handrail supports, one of these two bolts passing through the oblong hole of the step, the hole (s) round of the stringer and one of the holes in the support, allowing simultaneous adjustment of the horizontality of the step and that of the verticality of the handrail support.
  • the stringers (L) have two vertical sides (L1 and L3) parallel as, for example, constitute the large opposite sides of a tubular or semi-tubular section of rectangular or U or omega section. .
  • the ends of the steps MA are fixed on the inner face L1 of the profile. These ends are either folded to form a vertical part or secured to a vertical gusset (GM), which is pierced with two holes, a round front hole (TRM) and an oblong eye (TOM) the latter being oriented in an arc having a center (TRM).
  • GM vertical gusset
  • TRM round front hole
  • TOM oblong eye
  • the upright (MT) is integral with a trapezoidal gusset (GF) pierced with two substantially superimposed holes (GF1) and (GF2) ( Figure 1) or (GF3) and (GF4) ( Figure 3).
  • the lower hole (GF2) is a slightly arched oblong eye whose center of curvature is the center of the hole (GF1).
  • the round holes in the gusset (GM) of the step, the corresponding round hole in the stringer and the round hole (GF1) in the upright gusset are crossed by the same bolt (la).
  • the oblong hole (TOM), the corresponding round hole of the stringer and the oblong hole (GF2) are crossed by the same bolt (1b).
  • the vertical adjustment of the upright and the horizontality of the step is therefore made by pivoting the respective gussets around the fixed point constituted by the upper bolt by moving the lower bolt in the oblong holes.
  • the vertical distance of the bolts (1a) and (1b) corresponds to the difference in level between the steps, so that the stringer (L) is only pierced with three round holes located two by two in a plane horizontal (for bolts (la) and (1b) of the same step) and in a vertical plane (for bolts (1a) and (lb) of the same amount) so that on this stringer, the holes of these holes draw a broken line at right angles, which therefore does not weaken its resistance.
  • the lower hole (GF4) of the gusset is a round hole, while the upper hole (GF3) is oblong (lumen).
  • the upright (MT) is therefore articulated around the bolt (B) crossing the light (GM2) of the step, the round holes of the two sides of the stringer (L) and this lower hole (GF4).
  • the leveling of the step and the vertical setting of the upright require only three bolts, one of these being common to the assembly systems.
  • the staircases according to the invention find various applications such as emergency staircases subject to safety standards, because their design makes it possible to comply with the dimensions imposed by them (passage width, depth and height of steps, etc.). ''
