Description

Zusammengesetzte hölzerne Balken oder Stützen. Nach der Erfindung werden Balken, Stützen oder andere Bauhölzer aus zwei miteinander verbundenen halben Baumstämmen mit nach außen gerichteten Schnittflächen und gegeneinander gerichteten Rundflächen hergestellt. Dadurch wird die Tragfähigkeit erhöht, das Kernholz an die am meisten beanspruchten Stellen dds Querschnittes gebracht und es werden Vereinfachungen im Einbauen von Gefacha-usfül'lungen geschaffen.Composite wooden beams or supports. According to the invention beams, columns or other timber are made from two interconnected halves Tree trunks with cut surfaces facing outwards and facing one another Round surfaces produced. This increases the load-bearing capacity of the heartwood the most stressed points of the cross-section are brought and simplifications are made created in the installation of Gefacha-fillings.

Auf der Zeichnung ist ein Bauholz, und zwar beispielsweise ein Balken dargestellt. Fig. i zeigt den Querschnitt und Fig. a die Längsansicht des, Balkens.In the drawing there is a piece of timber, for example a beam shown. Fig. I shows the cross section and Fig. A shows the longitudinal view of the beam.

Nachdem der Baumstamm durch' einen Sägeschnitt in der Längsrichtung aufgetrennt ist, werden die beiden halben Rundhölzer a mit den runden Flächen gegeneinander gelegt und durch Querverbindungen b, die aus langen Nägeln, Bolzen, Klammern, aufgenagelten Holzleisten, Bandeisen o. dgl. bestehen, miteinander vereinigt. Um das Trägheitsmoment eines solchen Querschnittes noch weiter zu erhöhen, können die halben Rundhölzer durch einzelne Zwischenstücke c in Abstand voneinander gehalten werden. Die Querverbindungen b können, zumal nach den Auflagern hin entsprechend den schrägen Hauptspannungen; schräg gerichtet werden.After the tree trunk through 'a saw cut in the longitudinal direction is separated, the two half round timbers a with the round surfaces are against each other laid and through cross connections b, which are made up of long nails, bolts, brackets, nailed on Wooden strips, iron straps or the like exist, united with one another. To the moment of inertia To increase such a cross-section even further, the half round timber can are held at a distance from each other by individual intermediate pieces c. The cross connections b can, especially after the supports, according to the oblique principal stresses; be directed obliquely.

Durch die Neuerung wird der Vorteil erreicht, daß gewöhnliche unbearbeitete Rundhölzer verwendet werden können, daß das feste Kernholz und die größere Querschnittsmasse in den äußeren Querschnittsteilen angeordnet ist, daß also die Tragfähigkeit gegenüber vollep Rundhölzern wesentlich erhöht ist. Ferner eignen sich die Einbuchtungen zwischen den beiden halben Rundhölzern bei Balkenlagen sehr gut als Auflager für die Zwischendecke oder als Widerlager für kleine Gewölbe zwischen den Balken, wobei die üblichen angenagelten Leisten gespart werden. Bei Wänden finden in den Einbuchtungen, ohne irgendwelche besonderen Maßnahmen etwaige Ausmauerungen oder Wellerungen festen Halt.The innovation has the advantage that ordinary unprocessed Round timbers can be used that the solid heartwood and the larger cross-sectional mass is arranged in the outer cross-sectional parts, so that the load capacity opposite Vollp round timber is significantly increased. The indentations between are also suitable the two half round timbers with beam layers very well as a support for the false ceiling or as an abutment for small vaults between the beams, the usual being nailed Last can be saved. In the case of walls, indentations can be found without any special measures any brickwork or corrugations firm hold.

Die zusammengesetzten Bauhölzer erhalten in der ganzen Länge überall die gleiche Höhe, da die nach dem Zopfende zu abnehmende Stärke des Baumstammes durch verschiedene Stärkenbemessung der Zwischenstücke c sich ausgleichen läßt.The assembled timbers get everywhere in the whole length the same height, as the thickness of the tree trunk decreases after the end of the braid can be compensated for by different dimensioning of the thicknesses of the spacers c.
