Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The invention is explained in more detail below with reference to exemplary embodiments that are shown in the figures of the drawings, in which:

(2) FIG. 1 shows a schematic cross-sectional view of an OSB board according to a first embodiment of the present invention;

(3) FIG. 2 shows a lateral plan view of the view shown in FIG. 1 of an OSB board according to the invention,

(4) FIG. 3A shows a view of a first laying format of the OSB board according to the invention, and

(5) FIG. 3B shows a view of a second laying format of the OSB board according to the invention.

DESCRIPTION OF THE INVENTION

(6) FIG. 1 shows a schematic cross-sectional view of an OSB board 1 with a width of between 625 and 2800 mm, which is provided on each of the opposite board edges 2, 3 with a simple rebate 2a, 3a, the two rebates 2a, 3a being formed so as to complement one another.

(7) Correspondingly, the rebate 2a in the board edge 2 protrudes in a lower region of the board edge 2 and is set back in an upper region, whereas in the case of the complementing rebate 3a the upper region of the board edge 3 protrudes and the lower region is set back.

(8) The width of the two rebates 2a, 3a is in each case 30 mm. The depth of the rebate corresponds respectively to half the thickness of the OSB board; i.e., in the case of a board thickness of between 9 and 40 mm, the depth of the rebate is 4.5 to 20 mm.

(9) Provided in the surface of the rebate 2a is a rounded groove 2b as an insert channel for a glue tube or glue strip. The rounded groove 2b has a radius of 3 mm.

(10) Laminated on the upper side of the OSB board 1 is a layer of a cardboard paper 4 with a thickness of between 0.8 and 2.6 mm.

(11) The board edges 2, 3 including the cardboard paper 4 are additionally rounded (radius about 6 mm), with the board edge 2 having the rounding 2c at the set-back region of the rebate 2a and the board edge 3 having the corresponding rounding 3c at the protruding region of the rebate 3a. When joining the boards together, the roundings form with one another in the connected state a gap in the surface, which can be filled. The rebate 3a may have a raised web 3b with alternating symmetrical elevations arranged complimentary to the grooves 2b of the rebate 2a.

(12) FIG. 2 shows the embodiment of FIG. 1 in a lateral, perspective plan view. For this, the present OSB board can be used in various formats.

(13) In FIGS. 3A, 3B, two variants of the format of the present OSB boards are shown.

(14) According to a first format (FIG. 3A), an OSB board with a length of 2500 mm and a width of between 625 and 2800 mm, which is provided at the longitudinal edges with the profile according to the invention comprising a simple rebate and a glue tube, is provided. In this format, the end faces are provided with a butt join (i.e. without edging). This OSB board format is used in particular in a height equivalent to the height between floors.

(15) According to a second format (FIG. 3B), OSB boards with a length of 2500 mm and a width of 675 mm, which is likewise provided at the longitudinal edges with the profile according to the invention comprising a simple rebate and a glue tube, are provided. In this format, the end faces are designed with the known tongue-and-groove profiling, a rounding of the board edges preferably also being provided here. This OSB board format is used in particular as a board for laying.

Exemplary Embodiment

(16) An OSB/3 or OSB/4 with a thickness of between 9 and 40 mm, a length of 2500 mm and a width of 1280 mm is first provided in a laminating installation with a paper cardboard with a thickness of 0.8-2.6. It should be pointed out that these formats are only of an exemplary nature, and should not be regarded as limiting.

(17) Subsequently, a simple rebate is introduced along the two longitudinal edges in a milling installation. The rebates have in each case a width of 30 mm and a depth of 10 mm.

(18) The board edges are rounded. This takes place in tongue-and-groove installations, which are correspondingly equipped with tools for this or that profiling by changing them over.

(19) A rounded groove (radius of 3 mm) is introduced into the lower rebate by means of a milling cutter as an insert channel for a glue strip.

(20) A glue tube with a diameter of 9 mm, which consists of divided individual segments with a length of about 169 mm, is placed into the groove. The polyamide sheet material used for the glue tube has a thickness of 70-80 m. The glue tube is filled with a PVAC glue with a solids content of 65% by weight. Between the segments there is a sealing with a width of about 2 mm.
