Abstract:
A method of flooring using butting panels fixed to a frame primarily of joists, joints transverse of the longitudinal axes of the joists being largely unnogged. To support such joints unsupported by a framing element reliance is placed on panel edge to panel edge adhesion. In a preferred form particle board panels each provided with an edge groove have the effect of ensuring both a sufficient availability of adhesive for an effective butt joint whilst, in addition, providing a keying or splining between the adjacent panels.
Abstract:
A tongue and grove board has a first surface and a second surface, a first longitudinal edge and a second longitudinal edge and a first transverse edge and a second transverse edge. The first longitudinal edge has a first longitudinal lip and a second longitudinal lip cooperating to form a longitudinal groove therebetween, and the second longitudinal edge has a longitudinal tongue disposed therealong. The board further includes at least one notch disposed in the first longitudinal edge, the at least one notch extending perpendicular to the longitudinal edge, through the first surface and the first lip and partially into the second lip. The at least one notch has a depth at the first surface which is greater than the depth of the groove. The width of the longitudinal tongue is greater than the depth of the longitudinal groove, such that, when the longitudinal groove of the tongue and groove board is interfaced with a longitudinal tongue of an adjacent tongue and groove board, a drain path is formed between the boards, the drain path including the at least one notch in the first longitudinal edge.
Abstract:
The invention is directed to a tongue and groove product which comprises a first and second major surface and a first and second longitudinal edge. The first longitudinally edge includes a longitudinally-extending groove. The second longitudinal edge includes a longitudinally-extending protruding tongue for interlockingly engaging a complimentary grooved longitudinal edge of an adjacent tongue and groove board. The protruding tongue has an upper and a lower longitudinally-extending surface. The major design feature of this invention is that the protruding tongue has at least one substantially vertically-extending opening formed therein. Each of the openings extends through the protruding tongue from said longitudinally-extending upper surface to said longitudinally-extending lower surface for providing at least one drain path for water to drain by gravity from said first major surface downwardly through each said vertically-extending opening. This prevents an accumulation of water on the tongue and groove board. In the preferred case, the opening in the protruding tongue comprises a substantial vertically-extending notch.

Abstract:
An elongated floorboard is formed by finger jointing together in endwise fashion a plurality of relatively short sections of wood. The finger joints are formed at an oblique angle to the elongation direction of the floorboards to provide a repetitive series of visible joining lines. Floorboards having their joining lines in different orientations may be arranged adjacent to one another in various combinations to form floors having a variety of different patterns.
Abstract:
A tongue and groove plywood panel in which the tongue comprises a protrud lip having a triangular cross-section extending along the length of a first essentially convex edge. The essentially convex edge is formed by sloping surfaces that slope away from the junctions of the tongue and the first edge to the upper and lower veneers of the panel. The groove comprises a triangular cavity formed in a second essentially concave edge opposite the first essentially convex edge. The second essentially concave edge is formed with inwardly sloping surfaces that slope inwardly from the upper and lower veneers of the panel to the groove to form a shallow essentially concave channel along the second edge to guide and direct the tongue into the groove. When the panel is joined to a similar panel, the tongue of one panel engages the groove of the other and the veneers of the joined panels are spaced slightly at the joint due to the sloping surfaces of the first essentially convex edge sloping away from the adjacent sloping surfaces of the second edge of the joined panel. Such an arrangement allows for swelling of the tongue and groove joint of the present invention due to moisture without the buildup of internal stresses which would tend to cause buckling at the joint.
Abstract:
The present technology relates to connection joints for surface coverings which includes but is not limited to floor coverings and building panels. Embodiments of the present technology include connection joints that are strong and allow for the use of less material than is needed for tongue and groove connection joints. In embodiments related to floor coverings, these advantages are accomplished by reducing total thickness of a floor plank while increasing the thickness of the wear layer relative to the overall thickness of the floor plank and still be able to maintain a structurally strong connection joint.
Abstract:
Die Erfindung betrifft ein Verkleidungspaneel (10), umfassend eine mit einem Dekor versehene Dekorseite (10a), eine zur Anlage an einem Untergrund bestimmte Anlageseite (10b), und eine aus einem Holzwerkstoff gefertigte Verbindungsschicht (12), mit welcher wenigstens ein Verbindungselement (14, 16) einer nach Art einer Nut-Feder-Verbindung ausgebildeten Verbindungsanordnung einstückig ausgebildet ist. Erfindungsgemäß ist auf der der Dekorseite (10a) zugewandten Seite der Verbindungsschicht (12) wenigstens eine eine Zellenstruktur aufweisende Zwischenschicht (18) angeordnet, welche mittelbar oder unmittelbar mit einer die Dekorseite (10a) aufweisenden Dekorschicht (24) verbunden ist, oder/und ist auf der der Anlageseite (10b) zugewandten Seite der Verbindungsschicht (12) wenigstens eine eine Zellenstruktur aufweisende Zwischenschicht (20) angeordnet, welche mittelbar oder unmittelbar mit einer die Anlageseite (10b) aufweisenden Anlageschicht (34) verbunden ist.
Abstract:
Parquet board arranged for mechanical joint locking to corresponding parquet boards, for example, for a floor covering. The joint locking is achieved by one of the boards being provided with a groove (11) and the other with a tongue (12) at the meeting edges (14, 15) of the boards (1, 2), which tongue can be inserted into the groove. A locking arrangement in the form of a recess (32) in the groove and a projection (48) on the tongue achieves the locking by snapping together. A method for manufacturing the boards by chipping is described.
Abstract:
The invention is directed to assembly of a plurality of joined panel parts. Some of the individual parts contain a pre-applied curable adhesive to one or more sides or edges. An initiating metal activator is applied to complementing edges and cure is activated when the parts are assembled. The pre-applied adhesive system contains monomer(s), initiators, oligomers, an acid, and a sulfonyl compound. An activating or initiating metal foil, dispersion or coating is applied to the complementary surface. The bonding is effected when the adhesive system is activated by mating the edges. The activating metal is a reducible elemental transition metal. The metal is affixed to one surface which is brought into proximity with the curable adhesive compound dispensed onto the complementing part. The invention has usefulness in the joining of wood, wood products, composites of wood, thermoset polymer panels, non-initiating metal panels, and thermoplastic/wood composites, and the like to provide self-bonding assemblies having appearance surfaces, such as wall or floor coverings, especially assemblies that used joined board-like construction members.
