    Cross-sections of veneered elements joints

    Cross-sections of veneered elements joints

    The figure shows the cross-sections of veneered joints – veneered elements. A foreign tongue is most often plywood veneered with the same veneer as the facing side of the floor covering.

    Drawing. Types of carpet joints made of veneered elements – provideowanych: a) foreign tongue with a straight groove, b) foreign tongue with a trapezoidal groove, c) glued groove and tongue with a straight groove, d) glued in groove and tongue with a trapezoidal groove, e) butt joint with a covered foreign tongue, f) joint with glued notch and straight groove, g) joint with glued notch and widened straight groove, h) joint with glued rebate and widened trapezoidal groove, i) butt joint with concealed tongue and triangular groove

    Wrapping a foreign tongue and possibly the sides of the elements with a slightly lighter veneer than the front surfaces also makes a good impression.. if, for example, the elements are veneered with oak or elm veneers, the sides and feather can be covered with maple wood, birch trees, white ash, etc..

    Wood imitating plastic is not suitable for feathers, because it does not match the natural material.

    Of the examples of joint cross-sections given in the drawing above, the easiest and the most aesthetic one is the first (Lynx. a).

    If you want to plasticize the vertical wall covering, we have to use a different type of connector.

    Drawing. Wall lining made of veneered elements, alternately staggered.

    Drawing. Connectors of veneered elements of stepped lining: a) protruding elements are hammered perpendicularly to the floor covering, b) When the elements are pulled out, they are inserted into the slots.

    According to Fig. and the grooves are perpendicular to the wall. Elements adjacent to the wall must be well attached to the grate. Their spacing is also very important, that the distance between the grooves and the edges in both joined elements can be maintained. Make a template for the correct distance. Before being put into the groove, the tongues must be coated with glue. The tolerance of the dimensions of the groove and tongue should be such, so that the "dry" connector holds itself. Deviations of external elements from the vertical should be eliminated after pressing them.

    Easier assembly, but at the cost of reduced relief (12 mm in relation to 18 mm in the previous case), is obtained by using the second type of joint (Lynx. b). A 4X40 mm non-veneered plywood tongue is stuck and screwed to the rear of the protruding element with a tongue 7 mm. The protruding part of the plywood essentially forms a feather. Further assembly is the same as for flat coverings.

    The plasticity of the cladding can also be achieved by the method of one-sided overlapping of elements (drawing).

    The joint should then be adjusted to the angle of inclination of the applied elements.

    Drawing. A coffered ceiling lined with elements of different thickness.

    The figure shows a coffered ceiling made of elements of different thickness. The thinner elements of the lining are veneered on both sides, and on the circumference they have notches. Thicker elements consist of a spruce frame filled with ribs and covered on both sides with a hard fiberboard. The visible fibreboard is laminated with a drawing in a delicate grid. The joint is a strip of plywood glued and nailed to one of the elements.
