Description

Tongue and groove structure of the multilayer decorative panel

Tongue and groove configuration of a multi-layer decorative board for building as an interior decorative plates assembled architecture uses light ceiling, wall, floor or the like.

In modern large buildings, especially buildings of reinforced concrete frame structure, extensive use of high-strength, lightweight partition walls, covering indoor decoration materials. The current interior decoration materials, many varieties, different performance, which is a high-level wooden decorative plates decorative materials, commonly used in hotels, office buildings, offices, etc., in addition to its strength and some features waterproof, fire-resistant and other special requirements, for example, but also on the surface decorative effect, light body assembly have higher performance requirements, the prior art need to be improved to improve.

Object of the present invention is to provide a multilayer decorative panel assembled, it is reasonable tongue and groove assembly structure, easy assembly, increased strength, better decorative effect, and may be a thin lightweight.

The technical solution used, assembled configuration of the present invention is a multilayer trim panel peripheral edge and the tongue groove composed. Made of a plate-shaped reed, which is the upper surface of the light plane, which has a transverse groove on the bottom row of tidal flat bottom surface parallel to the upper and lower surfaces. Shape along both sides of its width (or length) of: one side of the central edge with protruding tenon, mortise edge of the notch and on the narrow gap, the gap width, the other side of the central groove, upper groove, the lower and the upper side with a projecting edge extending short length of the projecting edge. The respective projecting tongue edge, form a detachable mating splicing the width, the thickness dimension of the other side of the middle of the recess, the protrusion and recesses of the notch on the upper side of the tongue projecting edge width, corresponding thickness dimension, the flush splicing of two adjacent flat plates, each seams 0.5mm × 45 ° chamfer, the lower notch projecting tongue at the other side edge and the groove edge projecting the width, the thickness dimension of the corresponding two adjacent flat plates after the flush splicing. In the preferred embodiment, the side of a projecting tongue and the upper side, one triple lower half and the plate thickness of the gap, and on the other side of the recess, the extended side half and also one-third of the plate thickness.

Nowadays the technique of the present embodiment may have a bottom plane of the longitudinal and transverse moisture exhaust groove, a width between 3-6mm.

The present invention assembled multilayer decorative panels and similar products, which is easy disassembly assembling the combined structure, increasing the strength, stitching solid, reliable, and left to moisture exhaust groove, extended service life. Lightweight thin plate can be achieved, a better decorative effect, suitable for demanding architectural spaces.

Now the preferred embodiment in conjunction with the accompanying drawings be further described.

Figure 1 is novel when the tongue and groove configuration for assembling the floor, corner of the room a schematic view of practical use.

FIG 2 of the present invention is configured tongue and groove surrounding a detail, a longitudinal front view of FIG.

FIG 3 is a cross sectional view of FIG. 2 3-3 position, drawn as two change plate assembly adjacent perspective view.

Tongue and groove of the present invention may be configured for assembly room ceiling, wall panels, flooring and other purposes, FIG. 1 is a schematic view when a corner of the room floor.

See Figure 2 which is assembled configuration, FIG. 3, the periphery of the trim panel according to the present invention (longitudinal edges, transverse edges either or both) by a tongue and groove edges composition, the reed is made of a plate-shaped, which 1 to the upper surface of the light plane, bottom plane 2 on which a number of transverse rows of tidal grooves 3, the upper surface of the substrate 1 and the second parallel plane, along the longitudinal direction of both sides of the shape shown in Figure 2, along both sides of the edge shape its width Figure 3, one side of the middle with a tenon projecting edge 4, the edge of the tongue, and the notch 10 on the narrow gap, the width of the gap 11, the other side of the central groove 7, the groove, under extending edge and the upper edge 8 extending short length of the projecting edge 9, respective, form a detachable mating projection splicing the width, the thickness dimension of the tongue and the edge 4 of the groove 7, the tenon projecting edge 4 the notch 5 and the projecting edge 8 of the recess 7 width, the thickness dimension of the corresponding two flat plates flush with the adjacent stitching seams each 0.5mm × 45 ° chamfer 10. The tongue projecting edge 6 of the recess 4 and the lower protruding width of the groove 7, corresponding to the thickness dimension of the edge 9, after splicing two adjacent lower plate plane flush joints that are moisture exhaust groove 11, best Example: 4 and the tongue-side plate thickness of the gap 5 and 6 each accounted third, half and one third of the groove 7 and the thickness of the projecting edge 8,9. Width of the lower end of the longitudinal groove on the moisture exhaust plane 211 and the lateral grooves 3 for moisture exhaust 3-6mm.

Nowadays embodiment the substrate may be non-planar moisture exhaust longitudinal and transverse grooves.
