Definitions
- the present invention relates to a staircase for the stair tower based on a Modular scaffolding.
- the present invention further relates to the stair stringers and the associated stairs.
- the stair stringer according to the invention has an upper chord and a lower chord, which are preferably connected to each other by two end posts. Between The top and bottom chords are also attached to rungs the stairs are attached.
- these rungs have at least two slots which form the Reversibly pick up the suspension bolts of a stair step.
- the slots can be on the rungs in any manner familiar to those skilled in the art be attached.
- slotted plates are preferably welded to the rungs, into which Slots are incorporated.
- the slots in the rungs are also preferred punched, milled or embossed. Also preferred is one in the rung Slit pockets pressed into which the slots are worked.
- Each slot preferably has an opening through which the suspension bolts a step matching the stair string according to the invention in the Slots is insertable. Through this opening, the stair step can also from the slotted plate can be solved.
- a slot is parallel to the longitudinal central axis the rung and the other slot at an angle of 25 ° -155 °, preferably 45 ° -135 ° based on the longitudinal central axis of the rung.
- the angle is preferably 85 ° -95 °, very particularly preferably 90 °.
- the slot is preferably straight. At least one slot is also preferred L-shaped.
- the slots are 10 to 30 mm long and have a width of 8 to 20 mm.
- the stair string according to the invention has a low weight and is simple to manufacture. No additional detents need to be provided to to securely attach a stair step to the stair string according to the invention.
- the present invention also relates to a rectangular step, which has two suspension bolts on the circumference on two opposite sides.
- suspension bolts can have any shape. They preferably point however, a cylindrical part, on one end face a disc is attached, which has a larger diameter than the cylindrical part. This shape of the suspension bolts prevents the suspension bolts a step that is attached to the stair string according to the invention the slot is pulled out.
- Another object of the present invention is a staircase that consists of the stair stringers according to the invention and from the inventive There are stairs.
- Figure 1 shows the stair string according to the invention.
- Figure 2 shows a rung of the cheek according to the invention.
- FIG. 2 also shows how a stair step is attached to the rung.
- FIG. 2a shows a further embodiment of the rung of the stair string according to the invention.
- FIG. 2a also shows how a stair step is attached to the rung.
- Figure 3 shows slots which are punched into the rung.
- Figure 4 shows rungs with slotted pockets into which the slits are incorporated.
- Figure 5 shows the step of the invention.
- the stair stringer 1 according to the invention is shown in FIG . It has a lower flange 3 and an upper flange 2.
- the straps are connected to each other by the posts 12, 13. Rungs 4 are welded to the stair stringers.
- FIG 2 a rung 4 of the stair string according to the invention is shown.
- Two slotted plates 5, 6 are welded to the rung 4, the slotted plate 6 being attached near the lower flange and the slotted plate 5 near the upper flange.
- the slotted plates 5, 6 each have a slot 8, 9, which is fitted in the slotted plates 5, 6 such that each slot 8, 9 has an opening 11, 12 on one side through which the hanging bolts 10 of the step 7 can be inserted into the slot.
- the openings point in the direction of the lower flange.
- the slotted plates are arranged such that the longitudinal central axis of the slot 8 is arranged parallel to the longitudinal central axis of the rung, while the longitudinal central axis 9 of the slotted plate 6 is arranged at an angle of 135 ° with respect to the longitudinal central axis of the rung.
- This configuration has the advantage that a craftsman cannot step off the stairs when climbing the stairs.
- Figure 2 is also shown by arrows how the step 7 is mounted on the stair string 1.
- the hook bolts 10 are inserted into the slots 8, 9 and then pulled or pressed down the rear end of the step.
- the suspension bolt 10 is automatically pressed against the end of the slot 8. The same applies to disassembly.
- the suspension bolts 10 are pulled out of the slots 8, 9.
- FIG. 3 shows a rung in which the slots are punched into the rung.
- the slot 9, which is located in the vicinity of the lower flange, is arranged in the present case at an angle of 90 ° with respect to the longitudinal central axis of the rung.
- the slot 8 is L-shaped. This configuration in particular prevents the step from being stepped on.
- FIG. 4 shows a rung in which slit pockets are pressed into the side wall of the rung into which the slits are made.
- the stair step according to the invention is shown in FIG . It has two suspension bolts on the narrow sides.
- the suspension bolts consist of a cylindrical part 13, on one end of which a disk 14 is attached, which has a larger diameter than the cylindrical part 13. This undercut prevents the suspension bolts from slipping out of the slot.

Abstract
Description
Die Öffnungen weisen in Richtung des Untergurtes. Die Schlitzbleche sind so angeordnet, daß die Längsmittelachse des Schlitzes 8 parallel zur Längsmittelachse der Sprosse angeordnet ist, während die Längsmittelachse 9 des Schlitzbleches 6 in einem Winkel von 135° bezogen auf die Längsmittelachse der Sprosse angeordnet ist. Diese Konfiguration hat den Vorteil, daß ein Handwerker beim Besteigen der Treppe die Treppenstufen nicht lostreten kann.
