Description

Vierkantige Muffen: für die Stoßverbindungen von Ausbausektoren sind bereits bekannt, nicht aber kraftschlüssige vierkantige Reibungsmuffen, bei denen die beiden Stege in ihrem Gesamtquerschnitt dem Stegquerschnitt des Sektorenprofils und die beiden Gurtungen in ihr, -n Querschnitten denen der beiden Gurtungen des Sektorenprofils genau entsprechen. Auf diese Weise ist das Widerstandsmoment der bluffe genau so groß oder etwas größer als das des Sektorenprofils mit I-, U- Pokal- oder andern geeigneten Querschnitten, wozu auch eckige Rohrprofile gehören.Square sleeves: for the butt joints of expansion sectors are already known, but not frictional square friction sleeves, in which the two webs in their overall cross-section correspond exactly to the web cross-section of the sector profile and the two corrugations in it, -n cross-sections exactly correspond to those of the two cores of the sector profile. In this way, the section modulus of the bluffers is just as large or slightly greater than that of the sector profile with I, U cup or other suitable cross-sections, including angular tubular profiles.

Die hier vorgeschlagene und durch Abb, t bis 5 dargestellte Vierkantmuffe besteht aus Stahlguß oder gewalzten Vierkantrohrstücken oder aus stranggepreßtem Leichtmetallvierkantmaterial.The square socket proposed here and represented by Fig, t to 5 consists of cast steel or rolled square tubes or extruded Light metal square material.

Abb. n bis 4 zeigen, ein I-Profil für die Sektoren a, deren Stoßstellen durch elektrisch eingeschweißte Stoge b geschlossen werden, um die einwandfreie "Zwischenlagerung der vierkantigen Quetscheinlage c zu ermöglichen. Abb. 5 zeigt rechteckiges Rohrprofil für die Sektoren a. Die Muffe d ist peripherisch verschiebbar trotz der mehr oder weniger kraftschlüssigen Reibungseigenschaft .der Muffe. Dieser Vorteil der Verschiebbarkeit entfällt, wenn die Muffe konisch hergestellt wird, wie in Abb. 3 und' 4 angedeutet wird, d. h., wenn die Enden der Sektoren in warmem Zustande konisch zugeschmiedet werden. Stege e können zwecks Versteifung elektrisch eingeschweißt werden.Fig. N to 4 show an I-profile for sectors a, the joints of which are closed by electrically welded-in webs b in order to enable the correct "interim storage of the square squeeze insert c. Fig. 5 shows a rectangular tube profile for sectors a. The Sleeve d is peripherally displaceable in spite of the more or less frictional properties of the sleeve. This advantage of displaceability does not apply if the sleeve is made conical, as indicated in Fig. 3 and 4, that is, when the ends of the sectors are warm Conical forged bars e can be electrically welded in for reinforcement.

Die äußeren und inneren Begrenzungslinien der Muffen können Kreis-, Parabel- oder nicht konzentrische Bogenlinnen oder parallele oder gebrochene gerade Linien sein. Verstärkungs- oder Homogenisierungsrippen f können zweckmäßig vorgesehen %%-erden. Der Vorteil dieser \luften beruht auf dem denkbar geringsten Gewicht 1>:i Erzielung eines liöclisten Widerstandsmomentes, also der größten Bicgungsfestigkeit. Größte Homogenität der Muffen und Ausbauringe oder -rahmen wird auf einfachste Weise erreicht.The outer and inner boundary lines of the sockets can be circular, Parabolic or non-concentric arc lines or parallel or broken straight lines Be lines. Reinforcing or homogenizing ribs f can expediently be provided %%-earth. The advantage of this air is based on the lowest possible weight 1>: i Achievement of a liöclist section modulus, i.e. the greatest flexural strength. The greatest homogeneity of the sleeves and extension rings or frames is achieved in the simplest possible way achieved.

Auf diesen drei Eigenschaften beruht der erstrebte Fortschritt, die techyiizche Neuerung.The strived for progress rests on these three properties techyiizche innovation.
