Definitions
- the invention relates to a spiral staircase with individual steps made of stone, in particular natural stone, arranged on the spindle, the step having a reinforcing element.
- Spiral staircases of various types are known.
- a spiral staircase is known, in which the stone steps lie on steel tubs or steel brackets and the steel tubs or steel brackets are connected to the spindle.
- the production of such a spiral staircase with steel tubs or steel brackets is complex because a separate manufacture of steel tubs and brackets is required.
- the same also applies to spiral staircases with a steel stringer on the outer radius and often also on the inner radius of the spiral staircases, the steel trays being welded to the inside and outside of the steel strings.
- These constructions require a large amount of space and are also correspondingly expensive due to complex welding work.
- Such spiral staircases also always appear extremely bulky.
- spiral staircases of the type mentioned are known, in which the step consists of two horizontally divided layers, a reinforcement made of a glass fiber fabric being glued in between the two layers, and the individual steps being supported on one another by means of bolts.
- spiral staircases an extremely precise manufacture of the individual steps and a precise assembly of the steps is necessary, since on the one hand no horizontal gap may arise between the individual steps and on the other hand it must be ensured that the last upper step lies directly against the end face of the ceiling recess .
- These spiral staircases are limited to an outer diameter of 200 cm. Stairs of this type can hardly be used outdoors because there is a risk of frost due to the fact that the two stone layers loosen in the area of the glass fiber fabric.
- the invention is therefore based on the object of providing a spiral staircase which enables simple manufacture and assembly, and in addition the individual steps are not connected to one another, and consequently the individual steps are fastened to the spindle in a projecting manner.
- the reinforcement member can be connected at one end to the spindle and at the other end can be prestressed against the step by a tensioning element. That is, that the rod-shaped reinforcement member in particular extends through the step in its length and is stressed by the tensioning element in tension, the step as such being correspondingly stressed.
- a spiral staircase constructed in this way can be installed up to an outside diameter of 400 cm indoors and outdoors. Especially when building the stairs outdoors, it makes sense to make the metal parts made of stainless steel and for the steps a weather-resistant material, e.g. B. Granite to choose.
- the tensioning element is designed as a sleeve with an outwardly projecting, circumferential collar, the sleeve being connectable to the rod-shaped reinforcing member, and the circumferential collar abutting the front end of the stair step.
- the sleeve has a continuous internal thread, the reinforcing member corresponding to the internal thread of the sleeve having an external thread.
- the prestress can be applied to the step.
- a bolt for receiving the supports of a banister can be inserted into the sleeve from the outside. Since the sleeve has a continuous internal thread, a bolt provided with a corresponding external thread, which receives the support of the banister, can be screwed into this internal thread.
- the advantage of this is that this increases the width of the use of the stair step and thus the steps can be made narrower. According to the state of the art, it has been the case so far that in the case of finished spiral staircases, the supports of the railing are fastened at the top in the steps, and consequently a part of the width of the steps is lost.
- the spindle has a tab on its circumference, in particular made of steel, the reinforcing member being connectable to this steel tab, for example by welding.
- the tab itself is through one Screw connection connected to the spindle. Since each step is assigned a tab, assembly is relatively simple insofar as, after the spindle has been set up, only the individual tabs with the steps attached to them have to be attached to the spindle. The installation of the spindle can be made even easier by the fact that the spindle consists of individual elements which can be plugged together.
- Fig. 1 shows a section of a spiral staircase in a view
- Fig. 2 shows a section along the line II / II of Fig. I;
- Fig. 3 shows the detail "X" in an enlarged view.
- the spiral staircase designated overall by 1, consists of the spindle 2 and the individual stair steps 3 arranged on the spindle 2.
- the spindle 2 is composed of the spindle elements 2a, each spindle element 2a having a pin 2b at one end, which can be accommodated in the other spindle element through an opening 2c which is designed accordingly. That , The individual spindle elements 2a can be plugged together. Up to an outer diameter of the spindle of 300 cm, the spindle can be made in one piece.
- FIGS. 2 and 3 The design and the type of attachment of a stair step 3 to the spindle can be seen in FIGS. 2 and 3.
- the stair step 3 has two rod-shaped reinforcing members 4 made of steel which project horizontally through the stair step and which are welded to the bracket 5 at the spindle-side end are.
- the bores 3a for receiving the rod-shaped reinforcement members 4 are chosen larger in diameter than the diameter of a rod-shaped reinforcement member 4, so that there is a cavity 3b between the reinforcement member 4 and the bore 3a, which can be filled with mortar 6. So that stage 3 is now subjected to pressure, the sleeve designated 7 is screwed onto the rod-shaped reinforcing member 4.
- the sleeve 7 has an internal thread 7a and, corresponding to this, the rod-shaped reinforcement member 4 has an external thread 4a.
- the sleeve 7 also has an outwardly projecting circumferential collar 7b, which is supported on the end face 3c of the step 3 after screwing onto the rod-shaped reinforcing member 4.
- the pressure load acting on the step 3 increases or decreases. That is, the compressive stress on the step is directly related to the tensile stress on the rod-shaped reinforcing element 4.
- the spindle element has corresponding elongated holes 2d, through which screw bolts 8 pass, which in turn are connected to the tab 5.
- the arrangement of elongated holes in the spindle element 2a has the advantage that this makes it easier to align the step with respect to the distance to the respective neighboring step.
- a long wrench is provided for attaching the screws into the slot, with which the screw is guided and held through the inside of the spindle to the slot.
- a bolt 9 for receiving the support 10 of the banister can be screwed into the internal thread 7a of the sleeve 7.
- the nut 11 is provided, which can be tensioned against the circumferential collar 7b of the sleeve 7.
