Abstract

A steel tube is of rectangular cross-section and consists of two mirror-image C-shaped profiles (1). The two halves (1) are joined by a layer of high pressure laminate material (2) which has poorer thermal conduction characteristics than the steel (1), using a two-component glue.

Description

Die Erfindung betrifft ein Stahlprofil, vorzugsweise Hohlprofil, das aus verschieden geformten Stahlleichtprofilen, die ther­ misch von einander isoliert sind, zusammengesetzt ist.The invention relates to a steel profile, preferably a hollow profile, that of differently shaped lightweight steel profiles, which ther are mixed isolated from each other, is composed.

Stahlprofile werden als Standardhalbzeuge von verschiedenen Herstellern angeboten. Bekannterweise werden im Stahlbau auch Quadrat- und Rechteckrohre verwendet, die aus unterschied­ lichen Stahlleichtprofilen zusammengesetzt sind und meistens durch Schweißen dauerhaft verbunden werden.Steel profiles are used as standard semi-finished products by various Offered to manufacturers. As is known, in steel construction also used square and rectangular tubes, which differed from Lichen lightweight steel profiles are composed and mostly be permanently connected by welding.

Aus dem Kenntnisstand, daß Stahl eine hohe Wärmeleitfähigkeit besitzt und somit bei gleichzeitiger Beanspruchung durch Kälte auf der einen Seite und Wärme auf der anderen Seite als Wärmebrücke wirkt, ist der Einbau unter solchen Bedingungen bei Wohn- oder Geschäftshäusern mitunter mit der Bildung von Kondenswasser auf der warmen Seite verbunden.From the state of knowledge that steel has high thermal conductivity possesses and thus with simultaneous use by Cold on one side and warmth on the other as Thermal bridge acts, is the installation under such conditions in residential or commercial buildings sometimes with the Formation of condensation on the warm side.

Das erfindungsgemäße Stahlprofil wird als konstruktives Element dort eingesetzt, wo man einen schnellen Temperaturaustausch zwischen Innen und Außen durch Wärmebrücken verhindern möchte. (z. B. bei der Errichtung von Gebäuden).The steel profile according to the invention is used as a structural element used where there is a quick temperature exchange wants to prevent between inside and outside by thermal bridges. (e.g. when building buildings).

Dieses Stahlprofil, vorzugsweise Quadrat- oder Rechteckrohr, wird aus verschieden geformten Stahlkaltprofilen so zusammen gesetzt, daß die Berührungsflächen der einzelnen Profile untereinander verklebt werden können.This steel profile, preferably square or rectangular tube, is composed of differently shaped cold steel profiles set that the contact surfaces of the individual profiles can be glued together.

Zwischen jeweils zwei benachbarten Klebeflächen wird ein Streifen eines Materials, vorzugsweise HPL gefügt, das eine schlechte Wärmeleitfähigkeit aber ansonsten ähnliche Eigenschaften in Bezug auf Festigkeit, Ausdehnung u.ä. wie Stahl hat.A strip is made between two adjacent adhesive surfaces of a material, preferably HPL, which is a bad one Thermal conductivity but otherwise similar properties in Regarding strength, expansion, etc. like steel has.

Das gesamte Stahlprofil ist so ausgebildet, daß die einzelnen Teilprofile, aus denen dieses Stahlprofil zusammengesetzt ist, untereinander thermisch getrennt sind.The entire steel profile is designed so that the individual Partial profiles from which this steel profile is composed, are thermally separated from each other.

Die einzelnen Teilprofile können an beliebiger Stelle angeordnet werden, so daß aus jeweiliger konstruktiver Notwendigkeit eine thermische Endkopplung stattfindet.The individual sub-profiles can be arranged anywhere be, so that out of the respective constructive necessity thermal end coupling takes place.

Das erfindungsgemäße Stahlprofil kann überall dort eingesetzt werden, wo aus konstruktiver oder gestalterischen Gründen eine Anordnung erforderlich ist, bei der die eine Seite in einem kälteren Bereich liegt (Außentemperatur) und die andere Seite im wärmeren Bereich (Heizung von Innenräumen) und bei dem eine partielle thermische Entkopplung eine Wärme­ brücke vermeidet und eine Kondenswasserbildung verhindert.The steel profile according to the invention can be used anywhere there be where for design or design reasons an arrangement is required in which one side in one colder area (outside temperature) and the other side in the warmer area (indoor heating)  and where partial thermal decoupling is heat avoids bridge and prevents condensation.

Eine zusätzliche Verkleidung der Stahlprofile mit Dämmstoffen ist nicht mehr nötig. Das sichtbare Profil kann direkt als gestalterisches Mittel eingesetzt werden.An additional cladding of the steel profiles with insulation materials is no longer necessary. The visible profile can be used directly as creative means are used.

Beispielhafte Profile sind entsprechend der Fig. 1 bis 5 aufzubauen.Exemplary profiles are to be constructed in accordance with FIGS. 1 to 5.

Die Fig. 6 und 7 zeigen Verknüpfungen an einem Knotenpunkt. FIGS. 6 and 7 show links at a node.

Alle Profile werden ausgeschäumt. All profiles are foamed.  

Fig. 1 Fig. 1

Zwei gleiche C-Profile werden oben und unten an jeweils einen HPL-Streifen mit Zweikomponentenkleber verbunden.Two identical C profiles are on the top and bottom of each an HPL strip connected with two-component adhesive.

HPL = High pressure Laminates = Hochdruck-SchichtstoffplatteHPL = high pressure laminates
