Abstract

The wooden beam of uniform cross-section throughout its length is produced from a single tree trunk. The tree trunk is cut into four pieces (1) by longitudinal cuts on diametral planes at right angles to each other. Each piece produced tapers from the base to the tip and has a similar cross-section which reduces in size from base to tip. The four pieces are then re-assembled so that two bases and two tips are at each end with each base fitting between two tips vice versa. The four pieces are then glued together along their abutting faces to produce a beam with a uniform square cross-section. USE - Large timber beams.

Description

Der Erfindung liegt der Gedanke der größtmöglichen Rundholzausbeute zu Grunde. Der Verbund-Gegenstand besteht aus Einzelstücken.The idea of the invention is the greatest possible Log yield based. The composite object consists of individual pieces.

Die Einzelstücke der Verbundbalken bestehen aus Viertelstäben (Skizze 4) die aus Rundholz erzeugt sind.The individual pieces of the composite beams consist of quarter bars (sketch 4 ) which are made of round wood.

Rundholz hat am Stammende einen größeren Durchmesser als am Zopf (Spitze), ist also konisch.Roundwood has a larger diameter at the end of the trunk than on the braid (tip), is so conical.

Die Rundhölzer werden 4seitig konisch bearbeitet (gefräst, gesägt, gehobelt) und über Kreuz in Viertel­ stäbe getrennt (Skizze 1 u. 2).The logs are tapered on 4 sides (milled, sawn, planed) and divided into quarter bars crosswise (sketch 1 and 2 ).

Von den 4 Stck. Viertelstäben werden 2 Stck, um 180° gedreht, so daß 2 Zopfenden und 2 Stammenden zusammen­ kommen.Of the 4 pcs. Quarter bars are 2 pieces, at 180 ° rotated so that 2 braid ends and 2 stem ends together come.

Die Viertelstäbe werden wie in Skizze 3 zusammengelegt und verleimt.The quarter bars are folded and glued as in sketch 3 .

Die Verleimung erfolgt in 1, 2 oder 3 Arbeitsgängen. Es entsteht ein Verbundbalken der wieder 4 recht­ eckige Längsseiten aufweist.Gluing takes place in 1, 2 or 3 work steps. This creates a composite beam of 4 right again has angular long sides.

Claims (5)

1. Anspruch nach 1, dadurch gekennzeichnet, daß der Balken aus 4 Stücken (Skizze 4) eines Rundholzabschnittes besteht.1. Claim according to 1, characterized in that the bar consists of 4 pieces (sketch 4 ) of a log section. 2. Anspruch nach 1 + 2, dadurch gekennzeichnet, daß die Rundungen (Baumkante) beim verleimten Balken innen liegen und einen Hohlraum bilden.2. Claim according to 1 + 2, characterized in that the curves (Tree edge) on the glued beam inside lie and form a cavity. 3. Anspruch nach 1, 2, 3, dadurch gekennzeichnet, daß von den 4 Stück Viertelstäben eines Rundholzes 2 Stück gedreht sind und folglich jeweils 2 Stammenden und 2 Zopfstücke an jedem Hirnende zusammen liegen und verleimt, genagelt, geklammert sind. Je 2 diagonal liegende Stäbe haben gleiche Kantenlängen im Querschnitt (Skizze 3).3. Claim according to 1, 2, 3, characterized in that 2 pieces of the 4 pieces of quarter bar of a log are turned and consequently 2 stem ends and 2 braid pieces lie together at each brain end and are glued, nailed, stapled. 2 diagonal bars have the same edge lengths in cross-section (sketch 3 ). 4. Anspruch nach 1 bis 4, dadurch gekennzeichnet, daß die Viertelstäbe (Skizze 4) keine parallel zueinander liegenden Seiten­ flächen haben.4. Claim according to 1 to 4, characterized in that the quarter bars (sketch 4 ) have no parallel side surfaces. 5. Anspruch nach 1 bis 5, dadurch gekennzeichnet, daß der Balken aus konischen Hölzern verleimt ist und im ver­ leimten Zustand wieder 4 rechteckige Längs­ seiten aufweist.5. Claim according to 1 to 5, characterized in that the bar conical wood is glued and in ver glued condition again 4 rectangular longitudinal has sides.
