Definitions

  • the present invention relates to an outdoor metal staircase more particularly made of aluminum, for a multi-storey building or of a certain height, intended more generally for the evacuation, exit and / or entry from the outside, of persons of a multi-storey building, staircase which is designed so as to be essentially self-supporting so that if it can be provided for a multi-storey building to be constructed, it is particularly remarkable for an already existing multi-storey building which is just provided a means of evacuation or outside exit. Indeed, it may be simply attached to a facade of the building and not successively hung, that is to say carried by the facade of the building.
  • the present invention overcomes these drawbacks by proposing a new design, remarkable in addition, of a staircase which is entirely made in the workshop and of a particularly simple in situ assembly, without any welding, it requires no scaffolding, but a simple interlocking , bolting and possible riveting, and although most of the elements will be standardized, it is likely to adapt to storey heights outside of the usual heights (for example different from the current usual height of two meters seventy-five of a floor of a residential building with apartments) and therefore to old buildings, public buildings, industrial buildings, etc. Furthermore, it is easily possible to increase or decrease the depth, that is to say tell the distance from the end of the staircase and the facade against which it is placed. On the other hand, it is also designed so that it can be transported and shipped in pieces of a particularly reduced size.
  • the external metal staircase according to the invention is characterized in that it is essentially fixed and carried by four uprights forming a support column, placed vertically in a square or rectangle, around at least two sides, of which are fixed the flights of '' staircase, uprights assembled together at different heights and at least at landings, by four horizontal tie rods, one of the four of which will be located at a landing level, extends beyond a second upright to hold and carry on a whole side, this landing, or be fixed there to an existing landing, as well as fix the downward flight of this landing, and two tie rods of the four located at an intermediate landing extend beyond a amount to form part of the chassis of an intermediate bearing and fix there, on one of the two extended tie rods, the downward flight of this bearing.
  • the assembly of the various elements which will constitute the staircase is done by a system, partially by nesting certain elements together, partially by bolting, partially by riveting, all the elements can be prepared and cut to size at the place of manufacture.
  • 1 represents the brackets for fixing the staircase to the main structure, that is to say a facade 2 of a building (represented schematically by a typical floor), by 3 the vertical uprights which will constitute the support column 4 (fig. 4), by 5 the crosspieces of the railing on the inside of a flight of stairs, by 6 the crosspieces of the railing body on the outer side of a flight, by 7 the cross rails of a landing, by 8 (fig.
  • the chassis frame of an intermediate landing by 9 the stringers of a flight, by 10 the step of a flight, by 11 the floor sheet of an intermediate landing, by 12 the floor sheet of a floor landing, by 13 the base on which rests and is fixed the support column (uprights 3), by 14 the brackets for fixing the uprights 3 to the base 13, by 15 the three horizontal tie rods which will frame the vertical uprights 3 forming a support column and which are not extended beyond this, by 16 the two horizontal tie rods extending beyond an upright 3 of the support column 4 and forming a part of the chassis frame 8 of an intermediate bearing, by 17 the horizontal tie extending beyond two uprights 3 of the support column 4 and forming a part of the chassis frame 18 (fig.
  • the support column 4 forms a square, it is easy to see that it can also be rectangular, a flight of stairs therefore having a height different from the other two. If we increases or decreases the dimensions of the square or rectangle that the support column 4 can constitute, and therefore decreases or increases the height of the flights of stairs, these various possible modifications will therefore allow easy adaptation of the stairs to any height planned floor of a building to be constructed or already existing without even having to modify the slope of the flights of stairs, which of course also remains an (unimportant) possibility of adaptation to different heights; what is particularly remarkable in the invention is that one can simply, by modifying the dimensions (width, length) of the cross section of the support column 4 and without having to modify the distance standard that we set between the steps, get there.
  • the dimensions (width, length) and the square or rectangular shape of the support column 4 can be chosen for other reasons, aesthetic or according to the space available, indeed, it is possible, for the same height d 'floor, by choosing a rectangle rather than a square, rectangle whose length plus width also twice the side of the square, increase or decrease the distance, overall, between the facade and the outer end of the staircase.
  • a lower cut up 27a taking up half the height of the part 16a of this tie
  • a top cut down 27b taking up half the height of the part 16b of this tie and, opposite, on the same height, respectively a top cut, down 28a of the bottom part 16a of the 'other tie and a lower cut, upwards 28b of the upper part 16b of the other tie.
  • the back of the right U 33 is slightly extended upwards and has a small return 33c outwards, ensuring the perfect retention of the part U 33.
  • the uprights 20 of the railings of the floor bearings as, moreover, those of the intermediate bearings are simply fitted and placed inside the tie rods 17, 23 (and / or 16, 24), a cutout 34 being provided on the upper face of the upper part (17b, 23b) of these tie rods, the uprights 20, lying in the upper parts, then being riveted.
  • the two parts a and b of the tie rod 17 like all the other tie rods 15, 16, 23, 24 and as shown in B in FIG. 11, the parts a and b of the stringer 9 (identical profiles) are produced by means of two tubes a, b of generally rectangular profile placed upright, the upper b of which ends below with a straight U-shaped part 35, slightly smaller (see fig. 6) while the lower a ends above, in the extension of its sides, in a straight U so as to form a straight notch 36 in which the part 35 of the upper profile b will nest; the lower a having, further internally at the bottom, a reinforcement in the form of a straight U 37.
  • the uprights 20 in C, the uprights 20 have a simple rectangular profile identical to that of the uprights 19 , see D fig. 11, like that of the tie rods 40 (fig. 9). In practice, as visible in FIG. 10, the uprights 20 will rest on the end of the branches of the U 35 of the part 17b (or 23b, 24b, 16b).
  • the uprights 19 will be fitted and fixed by riveting in the manner that the uprights 20, except that they will be fitted into the upper part 9b of the stringers 9 and that the upright 19 will be cut into bias at its base so as to resume the slope given to the flight of stairs.
  • the crosspieces of the railing 7 consist of a round tube (E-profile, fig. 13) slipped into holes 38 provided right through the edges of the uprights 20, there is given in the corners a curvature 7a (FIG. 9) to these crosspieces 7 which are fixed by riveting to the uprights 20.
  • the crosspieces of the railing 6 consist of a round tube (profile in F identical to that in E, fig. II) slipped into a hole 39 provided in the edge of one side of the uprights 19, as perfectly visible in FIG. 11, the upper part (inlet) of the crosspieces 6 has been given a curvature 6a downwards so as to bring them back to the horizontal and vice versa at the lower part (departure) of the crosspieces 6, a curvature 6b upwards for the same reason and so that the crosspieces 6 slide straight into the uprights 19, to which they are fixed by riveting.
  • a curvature 6a downwards so as to bring them back to the horizontal and vice versa
  • the lower part (departure) of the crosspieces 6 a curvature 6b upwards for the same reason and so that the crosspieces 6 slide straight into the uprights 19, to which they are fixed by riveting.
  • the ramps 22 consist of a ⁇ -shaped profile (straight placed astride and fixed by riveting on the head of the uprights 20, it will be the same for the ramps 21 placed on the uprights 19 (not shown in detail).
  • Two of these wings are located near the longitudinal ends and have special arrangements, one 45 at the front is on the one hand longer than the other 44 and has a rounded return on the side facing back 47 d '' about a quarter of a circle with the outside diameter of a tube 41 which will thus be held at the same time by the inside face 43 of the step 10, the perpendicular part of the wing 45 and the round 47, the latter ends as visible in FIG.
  • the other wing 49 at the rear, longer than the other wings 44 is located at distance just greater, than that of the outside diameter of the tube 41, of the last wing 44 towards the rear so that the tube 41 is held between these two wings 44 and 49, preferably, moreover, as visible, l wing 49 has on the side of tube 41, a small boss 50 preventing, after force introduction, to tube 41 d come out.
  • the profile constituting the steps 10 preferably comprises, as shown, the means for fixing a step (not shown), means which consist on the one hand in providing at the rear end of the step 10, a wing additional perpendicular 51 provided with an outward return forming a straight hook 52 so as to provide a longitudinal groove 53 facing upwards, and on the other hand to be provided to the wing 45, 46, on the side opposite to the 'rounded 47, a straight hook 54 providing a longitudinal groove 55 facing downwards.
  • a counter step (not shown), a simple plate, will be perfectly held by being passed through the groove 52 pressing against the wing 51 of a lower step and taken into the groove 55 and pressing against the wing 46 of a step just above.
  • the first step starting from the bottom of a flight, for the opposite step, one will use, at one of the longitudinal sides, the usual means of fixing to the tie rods 16 or 17.
  • the part 58a (outside side) of slightly smaller diameter than the part 58b (inside side) and corresponding respectively to the outside diameter of the tube 41, respectively to the cut part 56 and its normal part, so that the stop 57 of the tube is stopped by the inner edge of the opening 58a of the stringer 9, we forcibly folds the end 59 of the tube protruding from the stringer 9 over its entire periphery and this ensures final fixing of the tube 41 to the stringer 9; one can also provide this fixing in a conventional manner, that is to say, by bolting for example.
  • the invention is not limited to the embodiment described and shown, in particular certain assembly details are not essential for obtaining a staircase in accordance with the general principles of the invention, but they nevertheless appear interesting in order to rationalize these components, to be perfectly aesthetic and to avoid complicated assemblies, in situ requiring the use of cranes, scaffolding, etc ... and / or work such as welding, heavy hanging to the facade of a building, etc ... while the in situ mounting of a ladder according to the invention will be carried out from the starting base 13 at a first height of the lower intermediate landing: first series of uprights 3 and tie rods 15, 16, 24, etc ... then, from this first bearing made, we will be able to make the second, etc ...
  • the number of intermediate bearings between two stages can vary but also, it can be envisaged, to reinforce the support column, to provide additional chassis-frames solely composed of tie rods 15 as other means, prop, square, etc ... and for example reinforcement brackets below the floor landing, moreover, the form of the embodiment of the steps 10 is capable of different realization, one can provide counter-steps, one can envisage that the floors both 11 and 12 and the steps 10 are constituted by a grating allowing evacuation of water and dust (sand for example).
