Definitions

  • the present invention relates to a support structure for a flight of stairs suitable for a stair run, which has at least one spar and is formed from a plurality of strung together, connected to one another and staggered support elements, on the one hand from the support of a step plate serving horizontal support bars and on the other hand consist of two connecting struts connecting each other, designed as pipe pieces, sleeves or the like.
  • the horizontal support bars and the vertical support struts are braced together by means of vertical support bolts acting as tie rods and passing through the support supports, and the inner diameter of the pipe pieces, sleeves or the like ... Are larger than the outer diameter of the support bolts.
  • the support supports each have vertical bores, through which the aforementioned support bolts then extend. Since these props are made of solid material, they are not only very expensive, but also have a high weight. Due to the large number of these props, the weight of the entire support structure is also quite large.
  • the object of this invention is now to be able to easily adapt this supporting structure, which is made of both metal and wood, together with its associated tread plates to the existing building conditions and dimensions.
  • the pipe sections or sleeves can be laterally displaced within the clear width of the supporting structure in relation to the supporting bolts passing through them in such a way that they assume an eccentric position with respect to the central axis of these supporting bolts and the neighboring ones on the outer shells of these tubular pieces or Sleeves adjacent tread plates can thus each take a position adapted to the intended staircase.
  • a preferred embodiment according to the invention is characterized in that the pipe pieces, the sleeves or the like are composed of parts glued together.
  • the use of such glued wood is particularly advantageous in that it prevents any cracking of the wood from the outset.
  • Each of the sections expediently extends only over a sector of the circumference of these pipe sections or sleeves, these sections then being able to be connected to one another again by tongue and groove.
  • These pipe pieces or sleeves can then be composed of 12 sections each.
  • the straight staircase shown in FIGS. 1 and 2 has a single-beam support structure 1, on the horizontal support bars 2 made of wood, a step plate 3, which is only shown in broken lines, is to be placed on each.
  • the horizontal support bars 2 are arranged in a row in a step-like manner, with each horizontal support bar 2 with its underside 4 being supported on the upper side 6 of the horizontal support bar 2 underneath via a sleeve 5 serving as a support and also made of wood.
  • support bolts 7 made of steel, serving as tie rods, each consisting of a round material, on the upper end faces of which a head plate designated 8 is screwed or welded, which is snug and flush in one in the top 6 of the support beam 2 machined cylindrical recess 9 engages.
  • the support bolt 7 is also assigned a clamping screw 10, the shaft 11 of which engages in a threaded bore 12 machined in the lower end face of the support bolt 7 and whose head 13 is supported by a washer 14 on the underside 4 of the support arm 2 in question.
  • the sleeve 5 As far as the sleeve 5 mentioned above is concerned, it is composed of 12 individual sections 15 with a trapezoidal cross section. A particularly high section modulus of this sleeve 5 can be achieved in that its inner diameter d is approximately twice as large as the diameter a of the supporting bolt 7 and thus between the supporting bolt 7 and the inner casing 16 of the sleeve 5 a cavity 17 with an annular cross section remains free. Should it be necessary in the case of special construction conditions or dimensions, this annular cavity 17 also allows this sleeve 5 to be offset eccentrically with respect to the support bolt 7 extending through it, as is shown schematically in FIG. 3, for example. In this case, the tread plate 3 resting on the support bar 2 is also shown, the rear edge 31 of which rests on the outer jacket 32 of the sleeve 5.
  • a continuous tubular body is first to be made, from which the sleeves 5 required in each case can then easily be cut to a length of about 16 cm to 19 cm at the construction site.
  • a cylindrical recess 18 is formed, similar to a bowl, whose diameter b is only slightly larger than the outer diameter D of the sleeve 5.
  • this recess 18 forms a secure fit for the sleeve edge 19 inserted into it, which is thus supported on the inner edge 20 of this recess 18.
  • a correspondingly dimensioned annular groove 21 is provided, how such is incorporated, for example, in the manner shown in FIGS. 4 and 5 in both the bottom 4 and the top 6 of the upper support beam 2. This annular groove 21 also results in a secure fit of the sleeve edge 19 engaging in this.
  • FIG. 6 shows, on an enlarged scale, a partial view of the sleeve 5 composed of several partial pieces 15.
  • all partial pieces 15 have a groove 22 and an associated tongue 23, each of which fits snugly into the groove 22 of the adjacent partial piece 15.
  • a sleeve 5 with this tongue and groove construction is characterized by a particular stiffness.
  • this support structure 1 according to the invention is provided for a straight staircase 24, the same components being identified again by the same reference numerals.
  • this support structure 1 is also suitable for a quarter turn 25 with the radius R, as shown in FIG. 8.
  • a cantilever arm 27 connecting the support structure 1 to an adjacent wall 26 and shown in section in FIG. 1 is additionally provided.
  • the end 28 of the associated support bolt 7 projects beyond the lower surface 4 of the support beam 2 and through an upper bore 29 into the hollow profile of the cantilever arm 27.
  • the previously mentioned clamping screw 10 is likewise provided, the shaft 11 of which extends through a bore 30 opposite the bore 29 and is screwed into a similar threaded bore 12 of the support bolt 7.
