Definitions

• the current Invention patent refers to improvements in the supports employed in the system for assembly and fixing of elevated floors, which simplify and optimize their installation.
• the elevated floor system is widely employed in spaces which requires the passage of electrical, telephone, logic cables, plumbing, air conditioning ducts, etc, and which should have easy and quick access, both for their maintenance, and also for any required changes in the "layout" of that space.
• the known elevated floors are composed of a metallic structure mounted directly on the floor or lowered sub floor of the building, over which are set out removable panels or plates made of wood or another suitable resistant material, on top of which is later placed the desired floor finishing, and said structure is composed of a multitude of pieces that constitute the support itself for the false floor.
• the known elevated floors mostly use supports composed of pedestals or vertical pins fitted with feet at their lower ends for fixing to the ground, and the platform at their upper ends where the panels or plates that comprise the floor are fixed directly, each of which fitted with means for adjusting the height.
• the document DE 38217422 shows a support configured by an angular metallic section, fitted with a L-head on which the floor plates lean on.
• this section presents only one side tab for supporting the plates, in order to get another side tab there are provided separate models with additional "clips", to be fixed by slotting into the vertical branch of the main section, resulting in an excessive number of pieces, and convoluted assembly.
• the document DE 19733647 shows a support configured by a metallic section formed by folds of a metallic sheet that forms an upper central branch, two side branches on which the floor plates rest, and two vertical and parallel feet with their inner-folded ends, making lugs for fixing at the far ends of the supporting feet.
• the object of this Invention is a elevated floor support fully structured and manufactured from suitable plastic material through the injection molding process, which support presents total constructive and operational simplicity, resulting, therefore, in a very low cost product.
• This new innovative support in its first embodiment option, is comprised of an inverted "U” section, upper and longitudinally fitted with a central vertical bar, or "crest", that delimits two horizontal side support and gluing tabs for the side edges of the floor plates in general (tiles, floor plates of any kind such as wood, aluminum, plastic, iron, shellacs, marble, etc.).
• the gluing of these plates can also be done only at the base of the four points, resulting in substantial saving in the glue applied.
• This support can be fixed directly to the sub floor by means of screws and bushes which go through small vertical cup shaped tubes a with a drilled bottom, which stick out from the lower side of the said side tabs.
• the side and vertical walls of the "U" section of the current support are fitted with a multitude of aligned empty stretches, that comprise spaces for the passage of cables, wires, piping, etc., that will be built- in under the false floor; the said empty stretches can be revealed in various formats, so that, in the preferred embodiment, these can be in the format of an arc.
• the same support can also be applied for supporting skirting boards and door stones, since that in such cases, it is enough that they are positioned at distances corresponding to the length and width of the floor piece in question.
• the central rule, or crest, provided for in the current support also configures an auxiliary element for the fitting and finishing between the plates and/or tiles that form the floor itself, so that, in case where it is necessary to apply grouting, the used amount of this product is substantially less.
• this first embodiment option for using the current support it can be shown without the central or crest bar, configuring, thus, an auxiliary support for the sustentation of large sized plates or tiles, and/or thinner plates or tiles, thus eliminating the possibility of chinks or cracks thereof (see Figure 9).
• said support is presented as an inverted "T" section, which vertical branch constitutes the same central bar, or "crest”, and the sustentation of this new section is made by cup shaped vertical tubes, with a central hole in the base, for fixing or anchoring to the sub floor, and that now, therefore, has also the purpose of very high impact sustentation.
• this crest divides the support into two tabs of equal widths, and serves as a division between the finished floor plates, and as they have a lower height, form a gap for application of the grouting to these pieces.
• Said crest also serves as the frame for the various formats of finished floors, whether rectangular, square, lozenge shaped, trapezoids, and or in parallelograms, and each side sector of the section with its cup-shaped pipes with a central hole in the base anchored to the sub floor, serve as sustentation for very high impact weight.
• said section is presented without the crest, and constituting extra reinforcement for delicate floors (with large sizes and thinner), and breakable.
• the support without a crest, leaned to and anchored to the vertical plane of the wall serves as sustentation for the gluing of skirting boards to the walls, supported at their base by a skirting piece and/or a piece of the finished floor (Figure 19).
• plastic "tick wall” extension sets which in their first version are comprised of vertical pipes and cup shaped fixing bushes with a central hole in the base, within which are fitted, inside or outside ( Figures 21 and 22), the lower ends of the vertical pipes, which, in turn receive the fitting, at their upper ends, of the cup shaped support pipes.
• the vertical pipe is shown provided with an externally threaded lower stretch, while the anchorage bush is tubular, lower and externally flanged, and provided with an internal thread, into which the lower end of the said pipe is attached.
