DESCRIPTION

Modular flooring.

Object of the invention

The present invention refers to a modular flooring, applicable in the construction sector for shaping floors and which is removable, reusable and easy to install. This modular flooring, being of the type comprising flooring modules that can be coupled to each other by means of connecting pieces, has particularities aimed at obtaining different separations between adjacent modules by mounting the connecting pieces in different positions.

Background of the invention

At present, in the field of construction, the use of different types of removable pavements is known, made up of plates or modules intended to be fixed to each other, forming as a whole the surface of the floor.

The union of these plates, in the case of removable pavements, is basically carried out by means of two types of unions.

A first joint, widely used in parquet flooring, is established by means of a direct tongue and groove joint of the adjacent plates, the wings or tongues and complementary coupling grooves being defined at the opposite ends of the plates themselves.

In these joints, the direct contact of the surfaces of the adjoining plates is generally pursued to define a continuous floor, that is, without grooves or separation joints between plates.

This type of direct joint between plates can be seen, by way of example, in the utility model ES1054288U, referring to an assembly system for parquet, consisting of a male part from which a longitudinal flange of a specific configuration emerges laterally, to its fit in a lateral channel of a female piece, thus forming a tongue and groove.

Utility model ES1062103 describes a device for joining parquet-type plates or tiles, by means of tongue and groove, similar to the previous one, and in which the plates include angular extensions arranged on the lower face of their edges, attached to flanges of said edges, which interconnect with recesses on the opposite edge of the adjacent plate, specifically in a lower flange, the hooking or coupling taking place in two perpendicular coplanar movements.

A second type of joints, clearly distinguishable from the one mentioned above, and closer to the invention, includes those joints made with the intervention of an independent connecting piece that is in charge of establishing the mutual fixing of the successive modules or pavement plates.

Within this second type of joints, it is worth mentioning, by way of example, the existence of the utility model ES1062104 in which a device for assembling parquet floors, formed by pieces of wood, or similar, equipped with a recess or similar, is described. perimeter channel accessed by a laminar connecting element provided with two lateral longitudinal bulges, each one of which enters the corresponding recess or channel with which the pieces of wood or the like are provided on the perimeter, this position being fixed with the help of at least one pair of elastic clips previously anchored in respective recesses defined in the lower face of said pieces of wood or similar, and in which said joining laminar element defines a profile whose core flush and serves as support for the flange formed in the pieces of wood, above the recess or perimeter channel.

The purpose of this device, like the previous ones, is to provide a direct contact of the attached parts, without mediating a joint between them, presenting the drawback of including, in addition to the joining piece or laminar element, the fastening clips of said piece. or joining element.

Utility model ES1063249 describes a device for joining removable floor tiles, of those formed by a lower wooden or similar base on which a ceramic or similar plate that constitutes the visible face is glued with adhesive, consisting of Spreaders that end in cylindrical bulges directed upwards, destined to fit tightly into respective machining of the lower base of the tiles, which affect the base of the wood. The wooden base has a perimeter groove for the introduction of the wings of a joint joint with an inverted “T” profile that forms an additional piece, with the consequent construction complication and that determines a single possible width of the separation joint. .

The technical problem that arises is the development of a modular flooring, which makes it possible to establish the fixing of the flooring modules "in situ", with two possible joint widths between adjacent modules and using only connecting pieces.

Description of the invention

The modular flooring of the invention is of the type that comprise flooring modules, preferably composed of a ceramic-stone plate fixed on a lower support element that has a longitudinal groove on at least two facing sides adapted for the coupling of some connecting pieces, and presents some constructive peculiarities aimed at solving the aforementioned problem, specifically to allow the "in situ" coupling of the flooring modules, using connecting pieces that, depending on their mounting position, allow different joint widths between adjacent modules to be obtained.

For this, and in accordance with the invention, the connecting pieces are made up of a longitudinal connecting profile, with a cross section, which has a central web from which symmetrical wings emerge laterally for their tight coupling in the longitudinal grooves of the modules to join; said central web extending vertically through the opposite ends in two opposite appendices and of different widths, destined to provide two joint widths between the adjacent modules, depending on the mounting position of the connecting profile and because the adjacent modules present on the opposite sides and in correspondence with the ends of the longitudinal grooves a longitudinal recess with a depth greater than half the width of the larger appendix and that defines on the side of the module a recessed surface with respect to the opposite surface, the appendages of the joining profile being arranged between two recessed surfaces and two surfaces of adjacent modules, the width of the appendix located between the opposite surfaces defining the width of the joint between adjacent modules.

The height dimension of the joint profile is defined by the joint height of the central web and the opposing appendices, not exceeding the height of the lower support element, so that in any of the preferred embodiments that will be described along the present memory, the correct arrangement and 180 degree rotation of the aforementioned joint profile is allowed, without the appendix located at the bottom, Regardless of whether it is the one that determines a smaller or larger joint width, it can protrude from the bottom of the support element.

The possibility is also contemplated that the aforementioned longitudinal grooves and recesses are made in the four facing sides of each module, forming respective indent surfaces that enable the arrangement of the longitudinal profiles on the perimeter and therefore, the union of four adjacent modules to each one. of these modules.

The different width of the vertical appendages of the joint profile allows two possible joint widths between adjacent modules to be chosen at the time of flooring installation, just by changing the mounting position of the joint profile, turning it 180 degrees with respect to its axis. longitudinal, to obtain one or another joint width.

In an exemplary embodiment, the lateral wings of the connecting profile have an initial section that extends into an intermediate section provided with oblique teeth, upper and lower, for their interlocking and retention in the groove of the corresponding module, avoiding unwanted movements during coupling "in situ" and finishing said intermediate sections in an end section with a tapered section, considering the possibility of it being rounded off.

The possibility is contemplated that the aforementioned indent surfaces of each module are arranged well below the longitudinal groove and that the opposite surfaces that define the joint width between the modules are arranged above the longitudinal groove or even an inverse arrangement, that is, the recessed surfaces arranged above and the opposite surfaces below the longitudinal groove.

The depth of the longitudinal recesses defined on the sides of the modules makes it possible, in the event of arranging between the recessed surfaces defined by said recesses, the appendix with the greatest width of the joining profile, to bring the facing modules close enough so that they contact against lateral surfaces of the appendix narrower, regardless of whether the recessed surfaces are arranged above or below the longitudinal grooves.

Referring to the lower support element that is an integral part of the modular flooring of the invention, it should be noted that although it can be made of any material such as polymeric, wood or others, it preferably comprises cellulosic fibers, such as chipboards made of wood fibers bonded with synthetic resins or even non-porous and high-density material formed by layers of cellulosic fiber material impregnated in thermosetting resins and joined together.
