Definitions
- the invention relates to a method for manufacturing a wooden hollow beam, rectangular in outline Composite construction, which consists of several, in the longitudinal direction of the wooden hollow beam, with each other connected, enclosing a cavity
- Individual elements is composed, being used for production of the individual elements of the hollow wooden beam to be manufactured
- First, one each from conical log sections Core plank is cut out, being a cuboid Core plank with a cut parallel to the core and a wedge-shaped core plank with a fiber parallel Cut is obtained and each of the two thereby resulting outer trunk segments with three separate External surfaces is provided and then the dried trunk outer segments perpendicular to Cutting surface for the core plank are separated, whereby the cutting surface dividing the outer segments is that the ends of the annual rings are not on one and emerge from the same cut surface and the middle outer surface parallel to the cut surface of the log section or processed parallel to the fiber, and that then four sorted individual elements accordingly in pairs turned longitudinally and cross-sectioned to one Hollow wooden beams are glued together.
- EP-A-0 388 507 also offers possibilities of combined individual pieces from different Round timber sections mentioned in these wooden beam formations and the procedures, however, is not included that the separation from the log section too no definition / cataloging can lead, but the basic usage pattern for many areas only to be determined on the semi-timber-like primary material is.
- EP-A-0 388 507 describes certain Bar shapes, but not with the primary aim of the inevitably different forms of raw wood the combinations of individual elements of different sizes, then the tree edge areas due to crossing of the center of the beam are to be processed, to use meaningful beam cross sections. Combinations from different raw wood diameters Formation of only one cross section (roughly that of the average diameter of the range of diameters used corresponds) are not provided.
- the invention has for its object a method to create hollow wooden beams that greater freedom of movement when compiling Individual elements to a hollow beam allowed to one better dimensional stability with changing moisture and in Long-term behavior leads and a safe closing of the Adhesive joints guaranteed and with that in economical The best possible yield with the least Committee is reached.
- Sawing parallel to fibers brings enormous advantages in terms of Crack formation, drying behavior and resilience.
- the materials from the wedge-like center piece can in turn be used for hollow beam production be used.
- sawing parallel to fibers there is no need so only a small part of what is not to wooden beams is to be processed.
- Figures 2, 3, 6 and 8 are not types of the invention according to claim 1.
- 1 shows the incision of log sections 1 as well as cuts to create the trunk outer segments as Material for hollow wooden beams 50.
- FIGS. 1 to 5 Through the incisions created in FIGS. 1 to 5 there are round wood parts or semi-wood-like ones Trunk outer segments 5, whose tree edge surfaces are not are pre-processed.
- Fig. 8 shows how a in the incision area (Fig. 1) separated trunk outer segment 5 in the wet state a segment 15 tri-surface-conical in compliance of a certain joint surface width 11 pre-processed 10 and is provided with relaxation slots 12.
- the vertical dashed line indicates that at a later also off-center separating cut the tree rings 9 always run out on two surfaces.
- Fig. 9 shows in principle a similar processing, it also points to the tree edge area processing 13, 14 and another type of relaxation slots 12.
- FIGS. 8 and 9 show that the Pre-processing is not always triple-conical takes place, but also only twice or in parallel can be done.
- Fig. 11 shows how the joint surfaces 10 by gradations 30 can be reduced.
- the bars 50 sketched to the right with a hole 51 in the middle show how uneven by combination large individual elements 21a always the same cross-sectional size 24a can be obtained.
- FIG. 13 shows two perspective views the hollow wooden beam 50 with the hole 51, the hole sizes 53, the edges 57 and the tree ring exits 55 in Corner area 54 and the tree ring exits 9 two surfaces.

- Procédé de fabrication d'une poutre creuse en bois (50) de section rectangulaire selon la méthode de construction composite, cette poutre étant composée d'éléments distincts (21) renfermant un espace creux (51), s'étendant dans la direction longitudinale de la poutre (50) et étant reliés les uns aux autres, procédé au cours duquel, en vue de la fabrication des éléments distincts (21) de la poutre creuse en bois (50) à réaliser, on découpe d'abord dans des rondins coniques (1, 2) un madrier central, de façon à obtenir un madrier central (4) de forme parallélépipédique si la coupe est parallèle au coeur et un madrier central (4) en forme de coin si la coupe est parallèle aux fibres et on ménage sur les deux segments extérieurs (5) du tronc résultant de cette opération, trois surfaces extérieures (6, 7, 8) distinctes les une des autres, puis on sépare (18) les segments extérieurs séchés (5) du tronc perpendiculairement à la surface de coupe (q) entre ces segments et le madrier central (4), la surface de coupe (18) séparant les segments extérieurs (5) étant agencée de telle manière que les extrémités des cernes n'aboutissent pas sur une même surface de coupe et que la surface extérieure intermédiaire (8) soit dégrossie parallèlement à la surface de coupe (q) du rondin (1, 2) ou parallèlement aux fibres, et on assemble par collage une poutre creuse (50) en bois à partir de quatre éléments distincts (21) triés en les inversant par paire longitudinalement et transversalement,
caractérisé en ce que
les segments extérieurs (5) du tronc sont découpés dans le rondin (1, 2) à l'état humide et les surfaces extérieures (6, 7, 8) sont dégrossies aussi encore à l'état humide,
en ce que pour obtenir des surfaces de contact (10) définies sur les surfaces extérieures (6, 7, 8), les zones (13, 14) du rondin situées entre les surfaces de contact (10) sont aplanies soit avant, soit après le séchage consécutif des segments extérieurs (5) dégrossis du tronc,
et en ce que les surfaces de contact (10) et les surfaces extérieures ultérieures (16) de la poutre creuse en bois sont ajustées à leurs dimensions finales à l'état sec. - Procédé suivant la revendication 1 caractérisé en ce que l'étendue des surfaces de contact (10) est réduite en prévoyant un décrochement (30) à partir des surfaces (13, 14).
- Procédé suivant la revendication 1 ou 2 caractérisé en ce qu'on pratique, de préférence de façon excentrée, une ou plusieurs fentes (12) de relaxation de contraintes dans les matériaux bruts humides (5), à savoir dans les faces opposées aux surfaces correspondant au coeur.
- Procédé suivant l'une quelconque des revendications 1 à 3 caractérisé en ce que, lors de l'ajustement aux dimensions finales (19) après le séchage, les séparations souhaitées (18) des segments extérieurs (5) du tronc sont pratiquées au milieu ou à l'écart du milieu.
