Description

FIELD OF THE INVENTION

The invention is in the field of metal construction and relates to a profiled metal plate for the simple construction of stairway and railing structures.

STATE OF THE ART

Wood is a renewable raw material which, due to its advantageous ecological balance, is also very popular for the production of outdoor structures such as excursion towers and platforms or treetop paths. In times of climate change, which is linked on the one hand to droughts and forest dieback, the question is increasingly whether it makes ecological sense to cut forests to obtain building material, especially since trees are urgently needed as CO ₂ stores and oxygen producers. Another disadvantage is that the production of prefabricated wooden construction elements results in a large amount of waste. Finally, if one wants to achieve a sufficient service life of the products, they have to be impregnated with chemicals, which runs counter to the requirement for high environmental compatibility.

Components made of metal, especially aluminum, could be alternatives. Although these are energy-intensive to manufacture, they compensate for this disadvantage in terms of their ecological balance due to their much longer shelf life and the absence of environmentally harmful preservatives. Since they are precisely poured into molds, there are no residues that have to be disposed of.

However, it is disadvantageous that corresponding metal or aluminum components are not easy to process. In particular, the assembly of stairs, paths or railings is complex and can usually only be guaranteed by screwing. This is especially true when these components have to be mounted on steel substructures, specifically on so-called "T-beams".

There are further difficulties with forged railings: The railings consist of an upper and lower flange and vertical round or square bars that are 12 to 14 millimeters thick. The upper chord, consisting of flat iron with a thickness of about 40x8 millimeters, must then be covered with a PVC handrail. As simple as such railings are, they require a lot of assembly effort and are associated with high manufacturing costs. The balusters must still be cut to length and the edges at the head ends must be heavily milled in order to be able to produce a clean weld seam. Once the individual parts of the railings have been completed in the workshop and the weld seams have been neatly sanded, they must be hot-dip galvanized before the actual assembly takes place. If they are then not given a good coat of paint on the outside, flash rust will settle on the top, which will soon make them unsightly.

STATE OF THE ART

Profiled metal sheets are known in large numbers from the prior art.

For example, the EP 2 476 853 A1 (JANSEN) a composite profile comprising an insulating profile and a metal profile formed by forming from a sheet material. A profile contour of the insulating profile is in a fastening groove of the metal profile with two opposite side borders ( 5 ) added, with the formation of a form fit between the insulating profile and the metal profile. The two side boundaries are formed by two profile sections which are connected to one another via a profile section in which the profile contour describes a profile loop. Profile sections of the profile loop adjoin one another in one area and are connected to one another in this area of their adjoining. With this construction method, a high degree of rigidity against bending open of the fastening groove can be achieved with relatively small sheet metal thicknesses.

From the EP 3 015 635 A1 B1 (SCHUECO) a composite profile for doors, windows or facade elements with a first metal profile and at least one insulating web is known, the first metal profile being connected in at least one insulating web zone to the one or more insulating web (s) and the one or more Isoliersteg (s) each has or have at least one end portion, wherein at least one of the end portions of each insulating web engages in a corresponding groove formed by the first metal profile, wherein the groove is formed from a bead and a web, the web on the circumference of a wire rests, which is inserted into the respective insulating bar.

OBJECT OF THE INVENTION

The object of the present invention was therefore to provide components made of metal which overcome the disadvantages of the prior art and are particularly suitable for the production of stairs, paths and railings. The main goal is easy assembly, which does not require screwing and allows problem-free application, especially on T-beam constructions.

DESCRIPTION OF THE INVENTION

1. (i) das Profil (2) erhaben ist,
2. (ii) das Profil sowohl an der Oberseite (3a) als auch an der Unterseite (3b) der Platte (1) aus zur Längskante (5) jeweils parallelen Zügen (4a ... 4z) der Höhe (H) und der Breite (B) mit dem Abstand (A) besteht,
3. (iii) die Züge (4) an der Oberseite und der Unterseite (3) gleiche Breiten und Abstände, aber unterschiedliche Höhen aufweisen,
4. (iv) die Platte (1) an einer oder beiden Längskanten (5) von einem Profilzug (4.1) begrenzt wird,
5. (v) wobei dieser Profilzug (4.1) einen L-förmigen Querschnitt mit einem langen Schenkel (7.1) und einem kurzen Schenkel (7.2) aufweist und der kurze Schenkel (7.2) dabei nach außen gerichtet ist.

A profiled metal plate is used ( 1 ) with a rectangular floor plan, where

1. (i) the profile ( 2 ) is sublime,
2. (ii) the profile on both the top ( 3a ) as well as at the bottom ( 3b ) the plate ( 1 ) out to the long edge ( 5 ) consists of parallel trains (4a ... 4z) of height (H) and width (B) with the distance (A),
3. (iii) the trains ( 4th ) at the top and the bottom ( 3 ) have the same widths and distances, but different heights,
4. (iv) the plate ( 1 ) on one or both long edges ( 5 ) from a profile train ( 4.1 ) is limited,
5. (v) where this profile train ( 4.1 ) an L-shaped cross-section with a long leg ( 7.1 ) and a short leg ( 7.2 ) and the short leg ( 7.2 ) is directed outwards.

The profiled metal plates are made to a fixed size - without "waste" and are placed on the substructure, preferably a T-beam or double-T-beam, and fastened with clips with a hammer blow. The short legs of the outer profile sections snap into the profile of the T-beam.

The profiled metal plates according to the invention are preferably made of aluminum, which does not require hot-dip galvanizing. However, the panels can also be powder-coated before assembly, which saves painting for the time being. Like a construction kit, the metal plates are manufactured in individual parts on machines or in sand or chill casting. Coupling these small parts with one another on site using the enclosed instructions for use and assembling the railing only takes a few minutes per meter, even for a layperson, so that the new components also significantly reduce the assembly effort.

With the help of precise joints that can be swiveled up to 45 degrees, i.e. cast parts that can be inserted as a slot in the head ends of the balusters using brass or plastic expansion dowels and plucked on the upper and lower chords of the infills, balusters can also be used must always be attached vertically to horizontal and rising railings.

If railings are produced on or on the metal plates according to the invention, there is a further advantage that all connections of handrails take place invisibly within the box profiles and can be covered by a hood. With the horizontal and rising railing infills, the upper and lower chords engage in the bores or millings of the vertical support posts and are clamped here to prevent slipping by means of a thin, flush grub screw. Alternatively, the handrails can also be latched using a bayonet lock. This means that additional thick end posts and struts, as is generally the case with outside railings, are not required. The invention thus also includes those profile plates which either have devices on their outside into which handrails can be inserted by means of joints, or which have a bore into which handrails can be latched by means of a bayonet lock.

Preferred Embodiments

The metal plate according to the invention can be made of steel, in particular V4A steel. However, it is preferably made of aluminum in view of weight and corrosion resistance.

Usually the metal plates

• • a length (L) from 0.5 to 3 m, preferably from 0.75 to 2 m and in particular from 1 to 1.5 m
• • a width (B) from 0.1 to 0.5 m, preferably from 0.15 to 0.4 m and in particular from 0.2 to 0.3 m, and
• • a thickness (S) -without profile attachment- of 1 to 5 cm, preferably from 1.5 to 4 and in particular from 2 to 3 cm.

The metal plates can be used over the entire length per 10 cm width 5 to 8th and preferably 6 to 7 profile pulls ( 4th ) wear.

The profile trains ( 4th ) can for their part

• • a height (H) from 0.5 to 5 cm, preferably from 1 to 4 cm and in particular from 2 to 3 cm,
• • a width of 0.5 to 2 cm and preferably 1 to 1.5 cm as well
• • Have a distance of 0.5 to 2 cm and preferably 1 to 1.5 cm.

The profile trains can have a constant width, but they can also taper from the base upwards or downwards.

The metal plates are also preferably characterized in that the profile trains ( 4th ) form a cross-shaped cross-section on the top and bottom and the height of the trains on the underside 10 to 100%, preferably 20 to 80% and in particular 30 to 50% of the height of the trains on the Have top. The profile pulls located on the underside of the metal plate mainly serve the statics and stability of the plate.

Furthermore, in a further preferred embodiment, the metal plates are designed in such a way that the L-shaped cross section of the at the longitudinal edges ( 5 ) located profile trains ( 4.1 ) a short leg ( 7.2 ), which directly into the T-shaped profile ( 9 ) of a steel beam ( 8th ) can snap into place.

In some cases, a thin connection between the individual metal plates that can be twisted slightly at an angle is required. This is particularly useful if the substructure consists of double T-beams, which, for example, rise differently on the outside like wooden strings on a spiral internal staircase - flatter on the outside, steeper on the inside. During assembly, the metal plates must therefore be pushed crookedly by the weight of a fitter, otherwise, depending on the length and width of the floor plates, up to five millimeters high stumbling edges would arise on the outside of the ramps, which in turn would represent a great danger when walking .

Composite systems

Still to be claimed

1. (i) a composite of metal plate ( 1 ) and T-shaped beam ( 8th );
2. (ii) a composite of metal plate ( 1 ), T-shaped beam ( 6th ) and brackets ( 9 ) with feather ( 11 ); such as
3. (iii) Stair, path or railing construction comprising or consisting of the composites as described above.
