Definitions

• the present invention relates to a method for making parquet, from end-of-timber blocks, placed on a screed or on a substantially flat existing sub-floor. It also relates to parquet or veneer, made according to the above-mentioned process.
• the parquet according to the invention is above all intended to cover a perfectly flat area of a sub-floor established in various materials, such as possibly reinforced concrete slabs, light concrete, raised floor slabs, for example in halls. computers, gymnastics, sports, museums, halls, multipurpose rooms.
• the arrangement of the blocks of end or bias wood implies that the wood fiber is substantially vertical or oblique.
• the present invention aims to avoid the above drawbacks and provides a method for making a parquet having an extremely hard wear surface, but flexible enough to absorb shock, minimal adhesion of dirt without being too smooth, as well as '' excellent thermal and sound insulation.
• the process according to the invention is essentially characterized by the fact that, for each of the blocks, lapped edges are provided, so as to hide from view any interstices separating two adjacent blocks
• o covers the sub-floor with a possibly etan layer of damping and thermal and acoustic insulation in resilient and elastic material, on which the above wooden blocks are fixed by gluing the underside of each of the blocks on said cushioning layer using an elastic adhesive.
• elements preassembled in removable tiles are produced, by assembling a determined number of wooden blocks on an elastic sole cut to the required dimensions, which is placed on the sub-floor.
• the damping layer of a substantially inextensible tram is covered.
• the invention also relates to a floor covering made up according to the method described below, this covering being essentially characterized in that it comprises blocks with smooth side walls placed on a damping layer, more particularly in foam of expanded polyethylene.
• FIG. 1 is a side elevational view of a parquet according to the invention
• FIG. 2 illustrates the elastic properties of the parquet shown in Figure 1;
• FIG. 3 is a view ' similar to Figure 1 of a parquet whose cushioning layer is provided with a substantially & inextensible weft;
• FIG. 4 shows a prefabricated laying element provided with a damping layer.
• the parquet according to the invention consists of blocks, slabs or pavers 1, most often made of wood or synthetic material, which cover a damping layer 2 of resilient and elastic material.
• These blocks 1 have a parallelepiped shape with smooth side walls 3, that is to say devoid of tabs or lateral grooves.
• blocks are used whose edges are slightly lapped, so that they are not sharp.
• the wood fiber is advantageously placed vertically or obliquely so as to avoid splinters, which makes the parquet safer in a sports or gymnastic hall.
• This inextensible film therefore makes the parquet safer, since it prevents the formation, between adjacent blocks, of a brutal discontinuity on which one could stumble.
• said frame strengthens the foam and prevents tears therein.
• the damping layer 2 is an extruded synthetic foam, it is in principle covered with a skin which is an integral part of its own structure and whose surface cells have not been sliced. In this case, this skin, much less elastic than the underlying cells, drives the neighboring blocks in the same movement. descending. This solution requires bonding the blocks to the foam with a flexible adhesive.
• the cushioning layer is on the other hand an expanded synthetic foam, it has cut cells.
• the adhesive used should be at least as elastic as the foam mat, so as not to cause any damage to the cells of the mat during the movements.
• the perforated or permeable film of the weft 5- may not contain micro- or macro-scopically cutting threads or fibers which would damage the carpet.
• the slightly spaced blocks are placed and the joints are filled with a translucent paste 6 making the blocks interdependent.
• This translucent paste can fluctuate in the interstices by following the movements of the blocks. It can be based on synthetic resins or be that provided for in Belgian patent No. 894.573.
• the point elasticity resulting from the installation of a damping layer 2 is different from the natural elasticity of a wooden strip.
• the damping layer according to the invention provides excellent thermal and acoustic insulation.
• the method makes it possible to assemble the blocks on a slab or strip 7 cut to the required dimensions so as to form a prefabricated laying element 8.
• Strip 7 can optionally include an adhesive layer on which the wooden blocks 1 are applied,
• the elements pre-assembled in removable slabs of a determined number of wooden blocks or the isolated blocks can be fixed on said damping layer in free standing or each glued on the damping layer
• the flexible sole of the preassembled elements allows laying of slabs on supports which are not in perfect condition such as, for example, more or less cracked or damaged screeds, or even on screeds intended primarily for simple carpets and not having the mechanical strength required to stick end grain to it.
• These preassembled elements do not necessarily have to be glued to the support, they can therefore be placed on lighter panels than those used when gluing the parquet on the support panel.
• edges of the facing face are advantageously lapped or chipped so as to hide from view any interstices separating two adjacent blocks.
• These lapped edges play the role of a plank chamfer. They serve to conceal any gaps between blocks, caused by the natural play of wood. This regularity of substantially identical visible joints over the entire surface of the parquet, provides a remarkable surface continuity effect,
• the installation of the preassembled elements when they are removable is done by simple gravity.
• a detachable glue is preferably used.
• To remove a slab we raises with a suction cup.
• the process according to the invention offers the following advantages: elimination of visible metal frames from removable raised boards; possibility of making the removable slabs of the raised support in inexpensive material; elimination of the setting of wooden blocks in metal frames flexibility of use wherever frequent access to electrical and heating pipes is required; possibility of replacing one or more tiles; beautification with wear; absence of splinters; acoustic insulation; high crush resistance; elastic feeling; thermal insulator; easy and quick installation.
