Description

The present invention relates to a double layer wall system, external elements for a double layer wall system, a set for manufacturing a double layer wall system, and a method for manufacturing a wall system and / or external elements.

WO 2008/087009 describes, for example, the external elements used for the assembly of lightweight partition walls. One wall section is fixed to the first flange of the outer element and the other is fixed to the second flange of the outer element. A "double layer" wall is a wall comprising two layers of wall sections (eg, plasterboard) that are placed on top of each other (contacting each other). Such a double layer wall enhances the stability of the corresponding wall system. Known contour elements are (eg, vertical) support components (studs) that absorb and transmit (eg, vertical) forces in the vertical direction.

Typical contour elements have a C or U shape that includes two flange sections connected by a web. Wall sections, such as gypsum plasterboard, are usually secured (screwed, riveted, nailed, or fixed by some other means) to the flange area. To provide a double layer wall, the first wall section is fixed to one of the flanges of the outer element and the second wall section is fixed through the first wall section into the corresponding flange of the outer element. It has been known. This arrangement is often repeated on other flanges of the outer element. Such a conventional double layer system improves the stability of the wall system, where the thickness of the wall system is increased.

An object of the present invention is to provide a double layer wall system with a high degree of stability and a relatively small thickness. Further, an object of the present invention is to provide a corresponding outer element, a set containing the outer element, and at least one wall section, and a double layer wall system, and / or a manufacturing method for manufacturing the outer element. To do.

The dual layer wall system according to the present invention specifically comprises at least one outer element having at least one first fixed surface and at least one second fixed surface, offset between the first and second fixed surfaces. (Offset) is provided, at least one first wall section, in particular the first plasterboard, is fixed to the first fixed surface, and at least one second wall section, especially at least one second plasterboard, is fixed to the second fixed surface. The first and second wall sections are placed on top of each other.

The term "overlapping each other" should preferably be understood to mean that the elements are in direct contact. However, it is also possible that an intermediate layer (eg, a coating layer or a metal sheet or the like) is placed between each element. In any case, the term "overlapping each other" should exclude the provision of (large) cavities between each element. The distance between the first wall section and the second wall section may be preferably 4 mm or less, more preferably 2 mm or less, and even more preferably 1 mm or less. The offset is preferably 5 mm to 30 mm, more preferably 8 mm to 18 mm, and more preferably 12.5 mm to 15 mm.

The core idea of the present invention is an outer element having two fixed surfaces, whereby the wall sections are arranged so as to overlap each other to form a double layer, and the two wall sections are (each). It is fixed to the external element. Stability is improved because each wall section is (directly) fixed to the external element. At the same time, the thickness of the double layer wall system can be reduced. Preferably, any of the above (and below) fixed surfaces is flat. Therefore, it is easy to fix the wall section to the external element. Two of the above (or below) fixed surfaces may, in particular, have an angle of 45 ° to 135 ° (eg, 90 °) with respect to the step and / or one and / or other (adjacent) fixed surface. It may be (structurally) separated by the additional aspects it has.

Preferably, the outer element comprises at least a third fixed surface, which is preferably arranged parallel to the second fixed surface, particularly coplanar. The third wall section (particularly, the third plasterboard) may be fixed to the third fixing surface. The second and third wall sections are arranged in parallel, particularly in the same plane so that the second wall section, the third wall section and the first fixed surface form a continuous (flat) surface. May be good. The third fixing surface simplifies the fixing of the third wall section so that a continuous double layer wall can be manufactured. Each wall section (second and third wall sections) can also be fixed in contact with both sides of the outer element so that the double layer structure is continuous through the outer element.

The outer element may include at least one fourth fixing surface for fixing at least one fourth wall section. Further, the outer element may include at least one fifth fixing surface for fixing at least one fifth fixing element. Further, the outer element may include at least one sixth fixing surface for fixing at least one sixth wall section. Preferably, an offset is provided between the fourth fixed surface and the fifth and / or sixth fixed surface. Further, preferably, the fourth wall section and the fifth and / or sixth fixed surface are arranged so as to overlap each other. Further, preferably, a cavity is formed between the second and / or third fixed surface on the one hand and the fourth and / or fifth and / or sixth fixed surface on the other. With such measures, the stability of the dual layer wall system is further enhanced without (substantially) increasing the overall thickness.

The second and / or third and / or fifth and / or sixth fixed surface may be located on the inside of the first and / or fourth fixed surface. Preferably, the second and / or third and / or fifth and / or sixth fixed surfaces are located within the cavity formed by the first and fourth fixed surfaces. Therefore, the thickness of the double layer wall system is relatively small.

The thickness of the second and / or third fixed surface preferably corresponds to the first offset. Alternatively or additionally, the thickness of the fifth and / or sixth fixed surface may correspond to the second offset. The term "correspondence" should preferably mean that the parameters (thickness on the one hand, offset on the other) are equal. However, the thickness-offset difference can be less than or equal to 10% of the amount of thickness. In either case, a compact and rigid double layer wall system can be obtained.

At least some of the external elements may have a hat-shape (in cross section). The "hat shape" is preferably a central surface, two intermediate surfaces having an angle (45 ° to 135 °, eg, 90 °) with respect to the central surface, and an angle with respect to the intermediate surface adjacent to the intermediate surface. Means a structure comprising two additional surfaces having (45 ° to 135 °, eg, 90 °). The hat-shaped portion is preferably an integrally molded body. Preferably, the cap-shaped portion is a cover that can be secured to the (conventional) C outer shape. Therefore, it can be adapted to the (conventional) C outline (or U outline, or I outline) so that a double layer wall system with good stability and small thickness is obtained.

In general, the outer element may include or consist of a cover that may be connected to or secured to the (conventional) outer element (C, U or I outer element).

In one embodiment, the outer element consists of an integrally molded body. This should preferably mean that the outer element is made from a piece (eg, made from one metal sheet). Alternatively, the contour element may be formed by two or more parts. When the outer element is an integrally molded body, the outer element having a high degree of stability can be easily created. If the contour element consists of two (or more) parts, it may have one or more hat-shaped covers and intermediate C, U or I contour elements, particularly connecting the hat-shaped contour elements. Is preferable. Such a system is just variable. What's more, those already made up of this system can be easily upgraded.

Preferably, the (at least one) first and / or second and / or fourth and / or fifth and / or sixth fixed surface are parallel and / or flat to each other.

As an independent aspect of the invention, external elements (preferably for and / or as part of the system) for supporting at least one wall partition, particularly at least one drywall plasterboard partition, , Web, first flange, first fixed surface, at least second and / or third fixed surface, where an offset is provided between the first fixed surface and the second and / or third fixed surface, and Includes a second flange as a fourth fixing surface. Such external elements make it possible to manufacture a thin and stable double layer wall system.

Preferably, the second fixed surface is provided on the web. The third fixing surface may be provided at the distal end of the first flange. The fifth fixed surface may be provided on the web. The sixth fixing surface may be provided at the distal end of the second flange. Such measures improve the stability of the dual layer wall system without (substantially) increasing the thickness of the dual layer wall system.

The second and / or third and / or fifth and / or sixth fixed surface may be flat. The second and / or the third and / or the fifth and / or the sixth fixing surface may be parallel to the first flange and / or parallel to the second flange, and / or the web. May be perpendicular to.

The second and / or fifth fixed surface may be formed by cutting out a part of the outer element, particularly the web, and folding the cut out part. In general, the fixed surface may be formed by protrusions (eg, rectangular). If part of the contour element is cut out and folded, it is a hinge from the contour element (especially the web) and thus provides a fixing point to support the (second) board. Such a structure easily creates and provides relatively high stability. Preferably, the cutout portion is used as a cutout for repair (eg, for installation of signals and / or power lines, etc.).

In such cases, the cutout portion serves two (completely) different functions, thus simplifying the structure of the outer element. In general, the invention particularly uses the use of cutouts of external elements (as described above) to provide a fixed surface, and preferably as a maintenance opening, and / or. Preferably, the openings for the installation of (signal and / or power) lines, etc., include, for use as, the second and / or the third and / or the fifth and / or the sixth fixed surface. Part of the element, in particular by rolling the web, may be defined by a protrusion specifically formed, such that the rolled portion of the outer element is provided with each fixed surface with increased rigidity. It may consist of double layers.

The external element may be an integrally molded body. Further, the outer elements may be made of metals, in particular aluminum and / or aluminum alloys and / or steel.

As an independent aspect of the invention, the set comprises an outer element having at least the first and second fixed surfaces, in particular for and / or the outer element for the dual layer wall system described above. The offset is provided between the first and second fixed surfaces and includes at least one wall section, in particular plasterboard, having a thickness corresponding to the offset. The offset is preferably 5 mm to 30 mm, more preferably 8 mm to 18 mm, still more preferably 12.5 mm to 15 mm.

b) Including the step of forming at least a second and / or a third fixed surface on the preliminary contour element, especially on the web (12), and / or at the distal end of at least one flange.

The external element may have a C shape, a U shape, or an I shape. The (first and / or second) offset may be 5 mm to 30 mm, preferably 8 mm to 18 mm, more preferably 12.5 mm to 15 mm. The external element may have a length of 15 cm to 400 cm. External elements may have a maximum width of 30 mm to 200 mm, preferably 50 mm to 100 mm (eg, defined by the maximum width of the web and / or the first and / or second flange). The at least one (or some or all) fixing surfaces may have a maximum width of 15 mm to 40 mm, particularly 20 mm to 30 mm, preferably 25 mm. The external element may have a (average) thickness (material thickness) of 0.3 mm to 2 mm.
