Definitions

  • the invention relates to methods for producing a hollow building board made of wood or wood substitutes, in which two originally full-walled part panels are fluted on one side, so that between standing webs trough-shaped depressions arise, after which the part panels glued to the end faces of the webs and with each other directed webs are pressed together.
  • Such hollow building boards are described in DE-C-30 44 039 and are essentially required for the production of doors.
  • the invention is based on the object of developing panels of different thicknesses which on the one hand can be produced in a process-favorably manner and on the other hand have high stability.
  • At least one partial plate is chamfered along at least one edge to the edge, so that webs of different heights are formed, after which the partial plate area weakened by the bevel is bent deformed against the webs of the opposing partial plate and the partial plates subsequently to Formation of a hollow building board with different thicknesses glued and pressed against each other.
  • the plate thickness it is possible to reduce the plate thickness over the entire plate circumference, or only a part thereof. If two adjoining plate sides are to be provided with such bevels, it is advisable in the sense of the invention to notch the webs in the region of the plate transition from normal to reduced plate thickness transversely to their longitudinal axis, or to break through in some other way. In this way it is possible to deform the layer (partial plate) provided with bevelled webs in such a way that in the corner region of the plate there is a kind of ridge between the differently inclined bevels of the plate.
  • At least one pair of channels lying opposite in the hollow building board is milled out to the edge of the partial plates and a profile with an adapted cross section is inserted into this pair of channels and glued or pressed to the partial plates.
  • Such profiles can be used according to the subclaims for different purposes, for example for the purpose of reinforcing the plate or the formation of a fitting for a plug connection of adjacent plates, or to create a basis for the introduction of threaded holes and the like connecting means.
  • Such usable profiles can be formed from a wide variety of materials, for example metal, with light metal profiles being particularly recommended. But when it comes to firmly anchoring connecting elements, such as screws, it is advisable to place them in the channels.
  • a partial cross section through a plate (1) is shown, which should have a bevel (2) on at least one side.
  • the invention is based on the assumption that this plate (1) is formed from at least two layers (partial plates) (3, 4), of which the layer (3), which contains the bevel (2), is cross-sectionally weakened and along the base plane ( 8) is connected to the other layer (45). It is of course conceivable to provide the other layer (4) with such a bevel (2) or to form the plate (1) from several layers. It is essential here that the face which contains the bevel (2) is designed with a weakened cross-section and is therefore designed to be deformable.
  • the individual layer (3, 4) consists, for example, of a solid wooden plate, in particular chipboard, into which grooves (5) are formed by machining.
  • the grooves 55) are preferably arranged parallel to one another.
  • the partial plates (3, 4) are shaped, for example in accordance with the shape according to FIG. (1). It is crucial here that the milling plane (9) according to FIG. (2) is brought into the basic plane (8) according to FIGS. (1) and (2) by deforming one or more of the partial plates (3, 4). It is easy to see that the partial plate (4) would also have to be deformed if it had a shortening of its webs (6) along a plane analogous to the milling plane (9).
  • bevels can also be made around the corner of a plate (1). It is only necessary to provide the webs (6) with notches (13) or other grooves along the bending line, provided that the associated partial plate (4) has to be bent along these notches (13).
  • FIG. (10) it is also indicated by dash-dotted lines how the channels (5) are designed in this case. It goes without saying that the pressing of the partial plates (3, 4) is maintained until the adhesive between the webs (6) has come off.
  • a tubular profile (15) instead of a tubular profile (15), a cylindrical solid profile can be used.
  • the profile can also be formed in the form of a rectangle (16) or a square (17).
  • a specially shaped profile for example an I profile (18) is also shown.

Abstract

Dans le procédé décrit, le panneau (1) se compose de couches (3, 4) dont au moins une (3) est affaiblie en section ainsi que chanfreinée et, après déformation en flexion, est liée à l'autre couche (4) par des techniques de collage et de compression. L'affaiblissement en section d'au moins une couche (3, 4) est réalisé par formage, par enlèvement de copeaux, de gorges (5) parallèles les unes aux autres; les parties intermédiaires (6) sont, aux endroits où le panneau (1) doit présenter des parois affaiblies (2), chanfreinées par usinage par enlevèment de copeaux selon un angle déterminé.

Claims (8)

1. Procédé de fabrication d'un panneau de construction (1) creux en bois ou en matériaux de remplacement du bois, qui consiste à évider sur l'une de leurs faces deux panneaux partiels (3,4) pleins de départ de manière à créer des mortaises (5) en forme de goulotte entre des moulures qui subsistent, à encoller ensuite les surfaces frontales des moulures (6) des panneaux partiels (3,4) et à presser ces derniers l'un contre l'autre par leurs moulures (6) dirigées en sens opposé, caractérisé en ce qu'il consiste à tailler en biseau jusqu'au bord au moins un panneau partiel (3,4) le long de l'un au moins de ses bords de manière à créer des moulures (6) de hauteurs différentes, puis à déformer en flexion la partie des panneaux partiels affaiblie par le biseau pour l'amener contre les moulures (6) du panneau partiel (3,4) opposé et ensuite à encoller les panneaux partiels (3,4) et à les presser l'un contre l'autre pour former un panneau de construction (1) creux d'épaisseur variable.
2. Procédé suivant la revendication 1, caractérisé en ce qu'il consiste, dans le cas d'une déformation en flexion s'effectuant transversalement à l'axe longitudinal des moulures (6), à encocher (13) ou à interrompre d'une autre manière le long de la courbe flexion, les moulures (6) des panneaux partiels (3,4) à la transition entre la partie obiseautée et la partie de la moulure qui reste non déformée.

4. Procédé suivant la revendication 1, caractérisé en ce qu'il consiste à mortaiser au moins une paire de goulottes (5) opposées dans le panneau de construction creux, et à insérer dans cette paire de goulottes (5) un profilé (15 à 19) de section transversale adaptée et à le relier aux panneaux partiels (3,4).
