"Cantilever staircase in steel and light metal construction"

The invention relates to a cantilevered staircase in steel as well as light metal construction with any running line, those from λ-zaagerecht arranged, carrying the treads Consoles can be screwed together, with each console on its bottom two each, the front and the rear Has tread area associated pipe pieces.

Similar stairs of this type of construction, but with only one screw, require tread bracing on the outside, such as also wall mountings at appropriate intervals.

The inventor has now set himself the task of further simplifying the known systems. By arranging the Adjusting screw, the usual step bracing on the outside could be omitted, as the static system also simplifies is.

The invention enables serial parts for all normal incline areas be used.

The object is achieved according to the invention in that the pipe sections assigned to the front step area have an internal thread over the entire length, while the pipe section assigned to the rear step area are designed to accommodate the screw heads of the adjusting screws which penetrate these pipe sections and the console from below, in the front pipe section of the console above it can be screwed in in a height-adjustable manner and can be fixed there if necessary. _i

With the construction according to the invention, only one bracket and two steep screws belong to each step The pitch of the stairs can be adjusted by turning the adjusting screws into the front pipe section to a greater or lesser extent be set precisely, so that one is not only dependent on a gradual fulfillment of the slope. Of special The advantage is that the staircase according to the invention can already be installed in the shell. It is then expedient to occupy them with wooden planks so that they can be used as construction stairs. The stairs can, however, with the appropriate The railing guide can also be used as a construction staircase without additional covering.

Further details of the invention, of which an exemplary embodiment is described and explained in more detail with reference to the drawings are specified in the subclaims.

2 shows a cross section through the console according to FIG. 1 along the line I-II

Fig. 3 is a side view of a fully assembled Staircase according to the invention using ■ consoles according to FIG. 1 and in

Fig. 4 is a front view of the stairs according to Fig. 3

The embodiment shows a console 10, which consists of a square steel or light metal plate 11 is made at their Bottom one or two front ones, with continuous internal thread 12 provided pipe sections 13, rear pipe sections 14 and connecting the pipe sections, the rigidity the plate 11 improving webs are welded. The pipe sections 14 have a through hole 16 with diameters which corresponds at least to the core diameter of the internal thread, and a hole in the area of the lower end pieces 17, the diameter of which is at least the head diameter of the associated screws and the associated socket wrench for screw actuation. The steel or light metal plate 11 can also be any have a different shape. The other mounting holes 18 are used for step mounting.

The assembly of the staircase according to the invention from the brackets 10 can be seen in FIGS. 3 and 4, respectively a console 10 and two adjusting screws with a thread Shaft, which corresponds to the internal thread 12 of the front pipe sections 13, form an assembly unit. The screw 20 is inserted from below through the rear pipe section 14 and the steel or non-ferrous metal plate 11 of a bracket 10, and in the front pipe section 13 of the console above screwed in until between a comparable level of the two consoles 10 the desired slope of the Staircase is set. The screw 20 can then be locked in a known manner. So will with the connection of all consoles 10 for all required steps.

The length of the front pipe sections 13 correspond exactly to the lowest step height that is desired in stair construction If you set a higher step height, this can be done from the pipe section 13 protruding portion of the screw can be covered by a decorative ring 21.

The front pipe section 13 of the console 10 assigned to the step is attached to a lower floor 23 on the lower floor Pipe flange 24 inserted, and can be determined there if necessary.

In a similar way, the rear pipe section 14 of the bracket 10 assigned to the exit step is via a mandrel 26 one attached to the end face 27 of the upper floor 29 Auxiliary console 28 inserted, and there if necessary This type of fastening of the uppermost console 10 ensures that the upper level with the storey floor 29 ends exactly.

Γ As soon as the individual bracket sections are set to the correct slope, they are braced against each other so that they cannot be loosened independently on the lower floor 23, and the auxiliary console 28 on the upper floor 29. Of course, it is also possible to pre-assemble the supporting structure in individual sections ₉ and then erect in sections. The steel or light metal plates 11 of the consoles 10 can then be temporarily covered with wooden planks or can be used as a construction stair using the existing supporting structure.

\ J preferably follows from natural or artificial stone, concrete, wood or steel or light metal steps.

The steps are screwed through the mounting holes 18 screwed to the console 10.
