Description

BACKGROUND OF THE INVENTION The present invention relates to a lightweight layered wood panel, with two distinct faces, intended for covering walls and ceilings, pillars and beams, walls inside or outside houses or other constructions, which can be easily and quickly mounted, making a independent, solidarity structure.

The panels are known from solid wood boards, with identical or distinct faces, with thicknesses between 12 and 22 mm. The mounting of these panels is done by previously creating on the wall a network of wooden slats trapped in the wall using the dowels. On this network of nails the panels are attached using nails or staples. the transverse jointing of these panels is usually done with the blade and groove but at the ends they are not processed with channels.

The disadvantages of these panels are the relatively large total thickness of the network of panels - panel, between 30 and 45mm, and this can be unsightly or impractical and can create problems of integration in the other building elements of the room: baseboards, doors, windows, furniture. Also, the mounting of the panels requires specialized workers as well as a relatively long duration. The weight of the mesh network is quite large and may require too much lightweight walls and ceilings of gypsum board. In the case of the walls and ceilings of gypsum-board, the fastening by means of the wooden slats forming the network is quite difficult because the gypsum-cardboard does not offer sufficient strength for the dowels in time and this greatly limits the assembly under the conditions in which the last years the interior walls of the buildings are made in a very large proportion of plasterboard. If the wall is not straight, the mesh network must counteract the wall unevenness and this is difficult to achieve if the person performing the assembly does not have adequate training and experience. The network of wooden slats that are fixed to the wall is formed by continuous slats along the entire length of the wall, which limits the air currents behind the panel, that is to an inadequate ventilation, an undesirable thing if the wall absorbs moisture and there is the risk of mold. and igrasia. In case of using noble wood essences the cost of the board is high.

There are known panels of chipboard wood, (PAL type, plywood or MDF), covered with wood veneer, the thickness of the veneer is approx. 0.6mm.

The disadvantages of these panels are that the finish of these veneer-coated boards is limited to coating with a varnish film, it is not possible to structure the wood in mass. For example, when structuring with wire brushes, a minimum thickness of 3mm of solid wood is required. Another disadvantage in this regard is that the veneers cannot be obtained from rustic-looking wood, with knots and cracks, and by default the panels made in this way will not have a natural-rustic appearance. The mounting of these panels is as troublesome as in the case of solid wood panels, and it is necessary to create a network of fences or metal profiles on the wall. Moreover, this type of panel does not allow, for aesthetic reasons, the fixing on the support network with nails, staples or screw-bolts, being necessary special clips. These accessories increase the cost and the duration of the installation.

At the presented types of board, only the longitudinal sides are processed with the slab and groove and the ends are generally not processed.

Also known are PVC panels that are lighter than solid wood panels or chipboard, which mimics wood, which is a disadvantage from an aesthetic point of view, and the wall clamping is as laborious as in cases. presented, with the related disadvantages.

The technical problem solved by the invention consists in the fact that a panel is made of laminated solid wood, with two distinct faces, with its own light weight and a reduced total thickness, which does not require the surface to be mounted and which can be mounted quickly by personnel

Ο 2 -05- 2011 unqualified (in DIY regime - Do it Yourself-) even on the surfaces of cardboard gypsum, without the need of accessories and additional materials, offering good ventilation between the panel and the wall to avoid mold formation and dimensional stability and resistance to changes in humidity in the atmosphere.

The invention removes the disadvantages mentioned by the fact that it is made of a light board type plate with two distinct faces, formed of a thin slab of dry wood at 6-8% humidity, with a thickness between 3mm - 5mm, which has a smooth upper surface and the lower face is solidified by hot pressing, with a pressing force of 2-10 kgf / cm and a temperature of 40-70 C, with some transversal elements of stiffening of softwood with a thickness between 4-8 mm and a width between 25-30mm, but not continuously but at a distance of 40-100mm from each other, making a sandwich-type stratified product in which the two layers are with the fibers oriented perpendicularly to create greater stability, and at the ends of the lamella is aligned a transverse element so that the lamella-element assembly offers sufficient thickness for mechanical processing with a Lamba and Uluc system and on the longitudinal sides a machining is performed sanfren type (the phase), the finished panel is finished with lacquer or oil on both the upper and lower faces, thus sealing the thin wood plate and preventing it from deforming by absorbing moisture from the environment, after which it mounts by local application on each transverse element two points or a continuous polyurethane or polymer adhesive string with elastic setting and fastening with a force by a simple manual press.

At the installation of two adjacent panels the transverse elements of stiffening will be arranged alternatively so as to create a gap to ensure a good ventilation of the space between the wall and the plate, and the processing with the plate and the groove at the ends allows the consecutive linear placement of several plates, joined together end by simply inserting one head (tongue) into the other head (groove).

When mounting the first row of panels, a spacer of 5-10mm is used, which provides a space for ventilation and to take over the possible dilations between the wall and the panel.

The panel made of panels can be mounted on walls and ceilings, pillars and beams, on the walls inside or outside the houses or other constructions, including on gypsum board.

The invention has the following advantages:

- increasing labor productivity by reducing physical effort and simplifying assembly operations. No qualification of the one performing the assembly is necessary and no other materials and accessories are required except for an adhesive with elastic setting;

- reducing the specific consumption of wood mass due to the reduced thickness of the wood board;

- reducing the cost of assembly;

- the installation with an adhesive with elastic setting has the advantage that in case the wall is not at level the possible unevenness can be taken over by increasing the amount of adhesive between the wall and the panel. This is achieved very easily by pressing more or easier to mount so that the girls of two consecutive panels are aligned at the same level.

- The reduced mass of this type of board makes it possible to mount it on any surface, including on plasterboard. If the plasterboard or the plaster on the wall is already applied a layer of lime or washable paint, it is necessary to clean only the hardening of the support by applying a primer of hardening and fixing.

- the offset arrangement of the slats - support allows an assembly to achieve a very good ventilation of the space between the wall and the panel;

- the total thickness of the panel type board is between 8-12mm to which is added the 2mm required for the adhesive with which it is fixed to the wall. A thickening of the wall is made with only 9-14 mm, this being beneficial due to the joints with other existing construction elements: baseboards, door frames, windows, etc.

- the processing of the ends of the plate with Lamba and uluc offers a continuous, very pleasant joint from the point of

Also, the longitudinal processing of the plate with the sanfren (the phase) offers the advantage that any imperfections that may occur during the installation will not be visible, aligning the edges of two consecutive plates under the plane of the facade.

The following is an example of embodiment of the invention in relation to Figures 1-4, which represents:

Example 1:

We are processing a 1 solid wood slat with dimensions: 2600 mm long, 150mm wide, 5 mm thick. It is recommended the essences of oak, fir, walnut, walnut, etc. 23 elements made of softwood 2 are rigidly bonded to the slab thus made for hardening, by hot pressing, with a pressing force of 4 kgf / cm at a temperature of 65 C, using a class D4 adhesive. The wooden elements have the following dimensions: 150 mm long, 25 mm wide, 5 mm thick

The sandwich plate made is mechanically processed in the following way: at one end the plate 5 and phase 6 are processed, and at the other end the groove 3 and phase 4 are processed.

The wood plate is processed longitudinally on both edges with phase 7.

The stiffening elements of the wood are arranged as follows:

- at the head processed with the tongue 5, the first stiffening element will be aligned with the head of the wooden plate, the next immediate element will be disposed at a distance of one and the next stiffening elements will be disposed at a distance 2a from each other.

- in the head processed with the groove, the first two stiffening elements will be disposed at distance 2a.

The panels thus made are finished with lacquer or oil on both the upper and lower sides. Finishing on both sides prevents the plate from deforming by absorbing moisture from the environment.

By bonding the cross-sectional elements, a sandwich-type stratified product is created, in which the two layers are with the fibers oriented perpendicularly and this creates greater stability, but at the same time the cross-sections being at a certain distance from each other reduces the weight of the stratified assembly. The weight of the lower layer in this case the transverse elements - is reduced to one third compared to the case if they were continuously placed next to each other.

The mounting of this panel type on a wall or ceiling is done by applying two points of polyurethane or polymeric adhesive with elastic setting on each transverse groove and then gluing it to the wall or ceiling by simply pressing. For added safety, a continuous adhesive strip can be used. The reduced weight of this type of panel makes it possible to mount it on any type of wall or ceiling, including gypsum board. The mass of a plate is small enough so that it does not detach from the wall or ceiling and it is not necessary that the panel be kept pressed until the adhesive hardens.

Prepare the surface on which the panel is mounted. If the plaster on the wall or ceiling is already applied a layer of lime or washable paint it is necessary to clean the surface and to apply a primer of hardening and fixing.

When mounting on a support wall 8, 8 mm dilation and ventilation spaces will be left at the ends of walls 9 and 10. The first plate 11 will be mounted with head 5 at the bottom and the second plate 12 will be mounted with head 3 in. the bottom, so as to create an alternation between the transverse stiffening elements.

The alternative arrangement of the stiffening elements will create a turbulent air current so that a higher ventilation of the space between the support wall and the wood plate is achieved.

The longitudinal processing with the beam allows to aesthetically place two plates next to each other% -2 0 1 1 - 0 0 4 1 1 -ο 2 -05- 2011 without highlighting the possible irregularities of the support wall, and the processing with the tongue and the groove at the ends allows the consecutive placement of several plates, joined end to end by simply inserting one head (tongue) into the other head (groove).
