Definitions

  • the invention relates to a component of a plurality of sheet-metal cassettes according to The preamble of claim 1, as well as a building with such a component.
  • a sheet cassette which has a back, two rectified, at right angles to the back bent webs, and from the webs parallel to the back two inwardly bent flanges has. At the flanges the edge is bent towards the back.
  • These Cartridges are lightweight in the longitudinal direction thanks to roll-formed embossing in the back arched. Also, a curvature of the back transverse to the longitudinal direction is proposed. These bulges serve to preload the cassette. thanks to the Preload spans larger spans can be bridged.
  • the cassettes can be combined to form supporting, flat structures and their webs with Screws are connected together.
  • From US-A-2,180,317 is a supporting component of a plurality of Sheet metal cassettes according to the preamble of claim 1 known.
  • the Sheet metal cassettes each have a back, two equally directed, right angles to the back bent webs and on the webs two mutually curved Flanges. At the flanges are stiffened edges to the back available.
  • the sheet metal cassettes are arranged bridge by bridge side by side and via a groove and a comb in the groove in adjacent webs connected together to form a planar component. Such components are remarkably viable, as the joined bridges together respectively form an I-beam.
  • the crest has the greatest external thickness, which is thinner than the largest Width of the groove into which the comb can be inserted. The difference is about the double thickness of the cassette. This game is needed for that Connecting parts between the webs can be arranged. In wider Webs can be formed a plurality of grooves or combs. Such cassettes can in different sheet thicknesses and different materials getting produced.
  • US-A-2,180,317 suggests adapting the load capacity of the structure, to choose the web width or the weight of the cassettes accordingly.
  • to Reinforcement of such structures in areas of increased load or at frontal bumps between two cassettes she proposes the integration of Connecting parts between the webs of two longitudinal side abutting cassettes and inner fittings in the cassettes before.
  • Cassettes with different heights can frontally or longitudinally be joined together, thanks to the groove and comb on one matching height are arranged. And that's the distance from Kamm and groove depending on the need for the flange back or back formed consistently.
  • the sheet metal cassettes each with a back, two equally directed, right angles to the back bent webs and on the webs two against each other formed curved flanges. They are jetty by jetty next to each other arranged, and abutting webs of the sheet-metal cassettes are connected with each other.
  • the component both at least a first Sheet cassette, which is formed from a sheet of a first, thinner sheet thickness is, as well as at least a second sheet cassette on which from a sheet a second, thicker sheet thickness is formed.
  • cassettes are more different Sheet metal frontally pushed to a cassette tape, and therefore arranged one behind the other.
  • To achieve an amplification of the bumps are These frontal collisions laterally adjacent cassette tapes shifted against each other.
  • the first cassette is roll-formed in this component, and the webs of the roll-formed first sheet cassette and the second sheet cassette lie over the entire length of at least one of the two sheet cassettes each other.
  • This allows the roll-formed first sheet cassette or the roll-formed first sheet cassettes with Standard dimensions to produce sheet thickness and cross-sectional shape. This in turn creates the conditions for cost-effective production a large number of cassettes.
  • the load situation is individual considered by the sheet thickness of the second sheet cassette and / or the Rhythm alternating between first and second sheet cassettes can be chosen.
  • This solution according to the invention takes a completely new route.
  • One Component of a plurality of cassettes forms a disc which is practical corresponds to an addition of simple bars.
  • the component is therefore static only sustainable in the longitudinal direction of the cassette. It is therefore surprising that not all cassettes for increasing the load capacity of the component need to be strengthened equally. It is enough incredibly, some of the cassettes, e.g. every third or fourth cassette, more sustainable form. But it is precisely this that makes economic progress possible Use of roll-formed first sheet metal cassettes in statically supporting components.
  • the roll-formed first sheet cassette standard dimensions in terms of sheet thickness and cross-sectional shape, and is the Sheet thickness of the second sheet cassette and / or the rhythm in the change between the first and second sheet cassettes tuned to the through the component load to be carried.
  • the first ones own Sheet metal cassettes of the inventive component advantageously a larger Sheet thickness.
  • the static load capacity of the sheet cassette is higher Sheet thickness greater, but the costs for the rollformer increase with increase of Plate thickness also on.
  • Advantageous sheet thicknesses are therefore in stainless steel between at least 1.5 mm and a maximum of 2 mm, preferably between at least 1.5 and a maximum of 1.8 mm. In the softer and more malleable Normal steel must or may be higher in thickness.
  • preferred Sheet thicknesses in normal steel are therefore between at least 2 mm and a maximum of 3 mm, preferably between at least 2 and a maximum of 2.5 mm.
  • the thickness of the first cassette can be selected within these limits. Because the component next to each other sheet metal cassettes different Has plate thickness, many intermediate areas of the load capacity between the Sheet thickness steps can be reached. To increase the bearing strength are between the roll-formed also folded sheet metal cassettes are inserted, the one may have significantly higher sheet thickness. Since these are folded Sheet metal cassettes thanks to the change with rollformed cassettes only in low number must be made, the component is still inexpensive produced.
  • the roll-formed first sheet cassette further has a uniform web width of at least 140 mm and a maximum of 260 mm and a uniform spine width of at least 350 mm and a maximum of 1000 mm.
  • the flanges advantageously have a width that is between at least 50 and at most 120 mm.
  • a preferred range is between at least 70 and at most 100 mm.
  • the optimal width is between 85 and 95 mm.
  • This training and these areas of sizing the rollformed first Sheet metal cassette on the one hand ensure the static load capacity of the cassette, which load capacity allows to use the sheet cassette as a supporting structure. On the other hand, these areas allow the economical production of Sheet cassette in rollforming process.
  • Such a sheet cassette is surprisingly versatile. That's how she works placed vertically as a supporting support and in combination with other vertical set sheet cassettes are used as a load-bearing wall panel. moreover can a plurality of similar sheet cassettes to a bottom plate be assembled. In many cases, the load capacity of the bottom plate insufficient for the exclusive use of roll-formed cassettes. It is then expedient, according to the invention cassettes with greater sheet thickness to interfere with the roll-formed cartridges of lesser thickness. This allowed to assume in the planning of a standard bridge width and the different load situations by the sheet thicknesses of individual, usually at the Square machine to make handmade cassettes.
  • the static bearing direction of the bottom plate is the cassette longitudinal direction. Transverse to the cassette longitudinal direction, such a bottom plate must therefore along At least two linear supports rest. Between the pads she can do one Span a room width of up to 10 meters.
  • the sheet cassette is in Roof can be used as a carrier shell, which is either horizontal like a purlin roof is curious, or like a rafter roof in the fall line is curious. It is Therefore possible, the support structure, as well as non-structural components, one Almost completely made of sheet metal cassettes. In contrast to conventional steel or wooden support structures this forms of sheet metal cassettes formed support structure closed surfaces.
  • the width of the edge is advantageous in a range between at least 5 and 50 mm, preferably it has at least 12 and no more than 30 mm.
  • An optimal margin width is between 17 and 25 mm.
  • This stiffening edge also has an effect on folded cassettes much stronger sheet thicknesses positive on the capacity of the cassette and therefore allows to minimize the sheet thickness.
  • each web has the roll-formed first sheet cassette advantageously a width between at least 160 mm and a maximum of 200 mm.
  • a compromise measure is chosen that can be used both in walls and in walls
  • Floors can be used to make the same rollformer for all sheet metal cassettes to be able to use. Therefore, a preferred width is at least between 175 and maximum 190 mm.
  • the back should not be too wide be.
  • the number of webs and their height in conjunction with the dimensions of the back loaded on the pressure and on. train loaded flanges significantly for their resilience.
  • the back of the roll-formed sheet cassette has a beneficial Width between at least 550 and a maximum of 750 mm, preferably between 600 and 650 mm up.
  • the sheet metal cassettes can be assembled on the construction site to form components become. Advantageously, however, they are already in the factory to components assembled. These components or components are then on the Construction site transported and moved by crane.
  • the thickness of the component can be used by transporting media in the cavities of the sheet metal cassettes be provided. So it is possible, the sheet cassettes directly as Ventilation ducts for heated air or conditioned air or cooled air too to use.
