Description

Description

The present invention relates to a mounting frame for a stair section.

Most staircases are currently made on site in one piece from concrete in accordance with local conditions in order to connect two floors. Such staircases are not standardized and must be individually adapted to the building to be equipped. In addition, spiral staircases, helical staircases and stringer staircases are also used to connect individual floors. With this type of staircase, the staircase is designed and manufactured according to local conditions. The individual parts are either assembled in advance or on site. With pre-assembled staircases, problems arise in particular during storage and transport, as these staircases have a geometrically complex shape. The assembly of such a staircase in a building that is essentially already completed is very difficult and associated with high costs. For staircases that are to be assembled on site, the individual staircase parts must be precisely prefabricated, and assembly requires a high level of craftsmanship. Since all staircases currently used are individually designed and manufactured according to local conditions, the costs of such staircases are very high due to the custom production.

Furthermore, auxiliary stairs must be provided for the construction workers on site, which creates an additional cost factor.

The object of the present invention is to provide an aid for the transport, storage, planning and assembly of a staircase, which enables standardized staircases and can be used universally for every type of building.

This object is achieved according to the invention by an assembly frame according to claim 1. The assembly frame according to the invention provides a self-supporting component to which a staircase section can be connected. A staircase can thus be assembled and used by the craftsmen before the completion of a floor. In particular, the storage and transport of pre-assembled staircases is significantly simplified and more cost-effective with preferably cuboid-shaped assembly frames. In the assembly frame according to the invention, the lower frame construction runs essentially parallel to the upper frame construction, so that the frame constructions can be installed in the floor ceilings or floors.

can.

Preferably, one of the dimensions of the assembly frame, i.e. the height, width or depth, is standardized. With an assembly frame in which one or, particularly preferably, all dimensions are standardized, the architect can select and plan a desired staircase from a certain number of standardized frames when planning a building. Standardized assembly frames enable correspondingly standardized staircases, which means that it is no longer necessary to design and build each individual staircase from scratch. Standardized assembly frames or staircase sections automatically allow the relevant staircase construction standards to be taken into account and met in advance. The manufacturing costs of staircases that are fitted into a standardized assembly frame are reduced by a higher production volume.

The lower/upper frame construction of the mounting frame according to the invention preferably has essentially the shape of a rectangle, wherein the

It is preferred that the mounting frame is at least partially made of metal profile strips. Metal profile strips with a closed cross-section or with an L-shaped cross-section are particularly preferred. A mounting frame formed in this way ensures a high level of stability of the mounting frame, and thus of the stair section mounted in the mounting frame, while being relatively light.

Preferably, the fastening devices in the assembly frame according to the invention are designed and arranged on a strut of the lower or upper frame construction in such a way that the end sections of the staircase section to be connected are essentially flush with the assembly frame. An assembly frame formed in this way enables material and space to be saved, in particular during production, storage and transport.

In order to increase the stability of the stair section in the assembly frame according to the invention, it is preferred that at least one connecting element is provided with a further fastening device for connecting a further point of the stair section. A stair section mounted in an assembly frame according to the invention thus has a high level of stability.

In the assembly frame according to the invention, the connecting elements preferably form a supporting structure for a staircase, whereby individual connecting elements are connected to one another by struts to increase the stability of the assembly frame. In particular, the lower/-

The upper frame construction has bracing. A mounting frame designed in this way creates a standardized staircase, which can be planned in advance by the architect in accordance with the building standards and regulations.

The mounting frame according to the invention is preferably formed in one piece, with the connecting elements being arranged perpendicular to the lower/upper frame construction. A mounting frame formed in this way has a particularly high

on.

As an alternative to the height standardization of the mounting frame, the connecting elements have a length adjustment device. By providing a length adjustment device, the mounting frame, and thus in particular the stairs, can be fine-tuned later.

A staircase section ,.- is preferably connected to the mounting frame according to the invention, which consists of tread elements and stringer segments each with two

lateral end faces. A connecting device is provided on each of the cheek segments in order to connect a tread element and/or another cheek segment, the connecting device being designed in such a way that a lateral end face runs parallel to a corresponding lateral end face of the adjacent connected cheek segment, preferably flush with it. In particular, a stair section formed modularly from tread and cheek segments is preferably mounted in the assembly frame according to the invention. The modular design of the stair section makes it possible to subsequently replace the entire stair section or individual segments.
Q20

Furthermore, it is preferred that the stair section connected to the assembly frame according to the invention has only a very small number of different elements. In a flat stair section, the stair is formed, for example, from a large number of identical stringer segments and a large number of identical tread elements. In a spiral staircase, two different types of stringer segments and a large number of identical tread elements are used in particular. It is particularly preferred that a height adjustment device and/or a relative vertical adjustment device is located between each of the stringer segments connected to one another, which enables subsequent adjustment of the stair section.

Finally, it is preferred that each stringer segment of the stair section connected to the assembly frame according to the invention has at least one lateral end face which is bevelled with respect to a lower end face of the stringer segment and runs parallel, preferably flush, with a corresponding lateral end face of the adjacent stringer segment.

In particular, it is preferred that the individual cheek segments essentially have a trapezoidal shape or a parallelogram shape. Such cheek segments can be produced in a particularly advantageous manner in a material-saving manner by cutting an elongated semi-finished product.

Further advantages, features and possible applications of the present invention emerge from the following description of an embodiment in conjunction with the drawing.

Fig. 1 shows in perspective an embodiment of a mounting frame

according to the invention with a modular staircase section mounted therein.

The assembly frame 1 shown in Figure 1 consists of a lower frame construction 3, an upper frame construction 5 and five connecting elements

7. The lower frame structure 3 is essentially rectangular in the embodiment shown, although circular segment-shaped frame structures (not shown) are also used, particularly in the case of spiral or helical staircase sections. In the embodiment shown, a vertical connecting element 7 is attached perpendicularly to each corner of the lower frame structure. Furthermore, a further connecting element is provided in the middle of one of the longer sides. An upper frame structure is connected to the upper ends of the connecting elements 7, which each have the same length. The upper frame structure 5 has the same geometric configuration as the lower frame structure 3.

A fastening device 9 is provided on the lower frame construction, to which a lower end section of a staircase section 50 is connected. The upper frame construction 5 also has a fastening

fastening device 11, to which an upper end section of the stair section 50 is connected. The stair section 50 fixed to the fastening devices 9, 11 consists of a plurality of identical circular ring-shaped tread elements 56, each with identical parallelogram-shaped stringer segments 54 and 52. The individual stringer segments 54, 52

and the tread elements 56 are connected to one another by means of a connecting device 58. The connecting device 58 and the cheek segments 54, 52 are designed such that the lateral end faces of the cheek segments are aligned with one another.

It should be noted that any other staircase sections, e.g. made in one piece, can also be used with the mounting frame according to the invention.

5 The mounting frame according to the invention thus provides an aid both

for both the architect and the craftsmen, with the help of which a staircase can be planned, designed, manufactured and assembled in a particularly simple manner. By standardizing the assembly frame, in particular the staircase components can also be designed in a standardized manner, whereby the manufacturing costs of a staircase are significantly reduced. A pre-assembled staircase section can be stored and transported particularly easily with the assembly frame according to the invention. With the assembly frame according to the invention, the overall construction time and costs of a building are also reduced, since it is no longer necessary to provide temporary staircases for the craftsmen. Finally, with an assembly frame according to the invention and a staircase section assembled in it, building regulations and standards can be implemented in a particularly simple manner, whereby the architect can take these into account when planning a building.
