Definitions
- Glued laminated wood element having, in cross section, cells, or the like
- the present invention relates to the field of wood processing, in particular for its use in framework, and relates to a glued laminated wood element having, in cross section, cells, or the like.
- the production of structural beams, or other is generally carried out by rendering of logs or logs with a relatively large production of edging, which are usual sawing by-products.
- These beams can also be made, in known manner, of glued laminated wood, that is to say in squared strips assembled by gluing to form a beam of square or rectangular section and of any length and shape.
- the slats are also obtained by rendering logs or round logs, so that the scrap falls are necessarily large, and all the more so when said logs and logs are of small diameter and / or of strong conicity, or even uniform.
- the quality of the surface finish of glued laminated timber beams is also linked to the presence of defects appearing during rendering, such as, for example, knots, which can have a harmful influence on the mechanical strength of the beams thus obtained, in particular when these defects are located in the external zones.
- the present invention aims to overcome these drawbacks.
- a glued laminated wooden element essentially constituted by an assembly of wooden strips comprising, inside the element, cells or the like, characterized in that the cells are delimited by a scheduling strips so that the edges corresponding to the outlines, or to the so-called "edge" woods, are arranged towards the inside of the element, these strips being fitted in such a way that two squared strips are arranged on either side another of two strips having edges corresponding to the outlines and delimiting between them a hollow.
- the glued laminated wooden element which essentially consists of an assembly of wooden strips, is provided between said lamellae of cells 1 delimited by a scheduling of lamellae 2, 2 ′ such that the edges which correspond to the edgings, or to the so-called "edge" woods, are arranged inside the element.
- These strips 2, 2 ' are fitted in such a way that two squared strips 2 are arranged on either side of two strips 2' having edges corresponding to the outlines and delimiting between them a hollow.
- Figures 2 and 3 show the embodiment of the element starting from a plate 3 ( Figure 3), which is delineated along two parallel generatrices 4 to form a square lamella A and two lamellae with non-delineated edges B and C
- the formation of an element in accordance with the invention is carried out by turning along the generator 4 of the strip B and by turning 180 ° then around the other generator 4 of the strip C, this embodiment being repeated until the desired dimensions of the element are obtained.
- FIG. 4 represents an alternative embodiment of the invention, in which the element is constituted by a staggered assembly of a square lamella 2 or not and of a non-edged lamella 2 ′ allowing a choice of the proportion of the cells 1 relative to the slats 2-2 'depending on the intended uses by increasing or decreasing the overlap, squared slats 2 being provided in the upper and lower parts of the element. Thanks to this embodiment, the non-delineated lamellae 2 ′ can have relatively large dimensions.
- the strips 2, 2 'used are advantageously obtained by selective trimming "without defect", that is to say that they have in their outer zones a continuity of the fibers, the nodes being maintained in the middle area.
- the aesthetic and mechanical qualities of the beam are reinforced in highly stressed areas, the usual wood defects being included in the mass of the elements or beams thus produced. Therefore, it is no longer necessary to remove, by purging the defects, a large part of the strips obtained by trimming.
- the cells 2 are used for carrying out a fungicidal, insecticidal or flame-retardant treatment, or for the passage of cables, sheaths, or cables or other steel elements allowing the prestressing of the element obtained, so that the qualities of the latter can be profoundly modified.
- the cells 2 can also form ventilation channels by means of a moving or stationary air knife, or fluid distribution channels.
- the cells 2 can be filled with insulating and / or flame-retardant material, or even metallic elements for structural reinforcement.
- the invention it is possible to economically reconstruct beams of any cross section and length by using almost the entire volume of material of the original logs or logs, whatever their initial length and conicity. It is thus possible to use and develop the usual by-products of sawing, such as edging, in the organized form of the original material, for the benefit of resistance.
- the appearance of facing can be achieved even with poor quality wood, and the good mechanical characteristics of the so-called "edge" wood are fully exploited thanks to the integration of these woods.
- the vertical inertia and the horizontal inertia are greater than that of solid beams with equal mass of material.
- the internal tensions are deleted.
- all of the woody material can be used.
