Description

The utility model relates to the field of construction, in particular to equipment for forming floor coverings consisting of slabs.

Traditionally, floor tiles are installed by laying them side by side on the floor surface. Typically, adhesive bonding is used to attach the tiles to the surface. The joints between the tiles are filled with hardening compounds. In this way, the tiles are bonded to a rigid surface, such as a concrete subfloor. This type of installation is expensive in terms of both tools and materials and also requires a relatively high level of skill on the part of the installer. In addition, after installation, it takes quite a long time before the flooring can be walked on. Another disadvantage is that the flooring installed using this system cannot be easily and simply removed, i.e. without damaging the tiles.

Currently, there are raised floor designs that allow you to create flooring on various hard surfaces without using adhesive bonding, as well as create horizontal platforms on terrain with elevation differences, with the simultaneous possibility of using the space under the floor for laying various communications.

These systems typically utilize a plurality of height-adjustable supports that are supported on the main floor and, when arranged in a grid pattern, support a plurality of removable floor panels at their upper ends. The space beneath the raised floor is used to route cables (power, data, and communications) and also accommodates or defines ducts for heating, ventilation, and air conditioning.

An adjustable supporting structure for a false floor is known (RU patent No. 2540723 C2), comprising a lower horizontal support, intermediate large and small couplings, an upper horizontal support, forming a vertical prefabricated and disassemblable stringer when connected by a thread. The structure is made of polypropylene. The disadvantage of this solution is that the false floor slabs are placed on a frame made of logs without any additional devices or fastening, due to which such a structure is highly susceptible to vibrations and risks from possible lifting of the slabs by the wind.

A solution for forming a floor covering is known (see https://thermo-pad.ru/), in which electrically heated slabs are installed on height-adjustable plastic supports, both with and without tilt angle correctors, depending on the slopes of the areas being used (https://thermo-pad.ru/, section "plastic supports"). The slabs are mounted on the supports using X-shaped guides (crosshairs), which allow for the formation of 4-5 mm gaps between the slabs and ensure unimpeded drainage of water between the slabs into these gaps and further along the drainage slopes (https://thermo-pad.ru/, section "drainage"). This solution is taken as a prototype of the proposed utility model. The disadvantage of this solution is that the slabs are placed on the supports without fixing, due to which such a structure is highly susceptible to vibrations and risks from possible lifting of the slabs by the wind. In addition, this solution has a limited scope of application, since it does not provide for the possibility of installing a frame made of logs, which is why it cannot be used in cases where high loads on the coating are expected, for example, installation of equipment, use in places where people may walk, etc.

The purpose of the utility model is to improve the connecting element for fastening floor covering slabs to a supporting structure.

A connecting element of a floor covering consisting of slabs, providing for fastening of the floor covering slabs to a supporting structure, containing vertical stops located on the upper side in the form of a cross and providing for installation of the floor covering slabs on the connecting element with the formation of a gap between adjacent slabs, according to the utility model is made in the form of a disk made of rubberized plastic and includes snap fasteners for fixing the connecting element to a frame made of joists, located on four sectors of the circle of the lower side, and a central hole used for fastening the floor covering slabs to the connecting element and the frame made of joists with a self-tapping screw and a washer.

The technical result is an increase in the reliability of fastening floor covering slabs to the supporting structure.

Due to the presence of snap fasteners located on four sectors of the circle on the lower side of the connecting element, a rigid fastening of the connecting element to the frame made of joists is ensured, which in turn increases the reliability of fastening the floor covering slabs.

By fastening the floor covering slabs to the connecting element and the joist frame with a self-tapping screw and washer, the floor covering slabs are rigidly fastened to the disc and the joist frame, which increases the reliability of fastening the floor covering slabs.

Due to the fact that the connecting element is made in the form of a disk made of rubberized plastic, the floor covering made of slabs is not subject to vibrations caused by operating equipment or people walking, which significantly reduces or eliminates the possibility of loosening the threaded fastening with a self-tapping screw during operation, which increases the reliability of fastening the floor covering slabs.

Fig. 4 and Fig. 5 show exemplary views of the floor covering as a whole, obtained using 3-D modeling.

The floor covering in which the proposed connecting element can be used includes (Fig. 2):

1 adjustable support of the required height, consisting of a base, a top and a spacer coupling, if it is necessary for the height of the supports specified in the project;

fastening 2 clip, allowing to firmly connect the upper part of the adjustable 1 support with the frame of the logs, thanks to the grooves made in the log 3;

3-log frame with specialized grooves for connecting fasteners;

a connecting 4 element of the floor covering, having a fastening element 10, which is joined with the grooves of the joist 3 on the lower part, and an upper part with vertical 11 stops, necessary for creating gaps of 3-6 mm between the floor covering slabs, for example, for draining melt water;

a floor covering slab (not shown in the figure) placed on top of the connecting element 4, with the formation of a gap between adjacent slabs due to vertical 11 stops made on the upper surface of the connecting element 4.

The connecting element 4 of the floor covering, which ensures the fastening of the floor covering slab to the supporting structure (raised floor), is made in the form of a disk with a diameter of 100-150 mm made of rubberized plastic, which also allows it to perform a shock-absorbing function, avoiding vibrations of the floor covering slab against the fastening element during intensive walking or from operating equipment. A variant of rubberized plastic can be high-strength polyurethane plastic. Also, a thermoplastic elastomer can be selected as the material of the disk 4, which has the advantages characteristic of both rubber and plastic materials. The advantage of using high-strength polyurethane plastics and thermoplastic elastomers is their ability to stretch to a certain extent and return to their original shape, which ensures a longer service life and better physical characteristics than other materials. Thus, higher performance indicators of the use of disks 4 in the application with the installed floor covering slab are achieved. A raised floor with such disks 4 does not rattle, vibrations from walking and operating equipment are dampened, and due to the increased tensile characteristics, the service life of the raised floor increases.

On the lower part of the disk 4 there are fasteners-latches 10 (see Fig. 1a and 1b) for fixing to the grooves of the joist 3. The latches 10 are located in four sectors of the circle and provide the necessary location of the disk 4 on the joist 3 for further laying of the slabs. The shape of the latches 10 in the form of L-shaped elements allows pressing the disk 4 to the joist 3, and the beveled outer elements provide convenient latching. If necessary, the disk 4 can be removed from the joist 3 by pressing the latches 10.

On the upper part of the disk there are (see Fig. 1a and 1b) vertical 11 stops for ensuring even seams when installing floor covering slabs. The size of the vertical 11 stops: height 10-30 mm, length 10-30 mm and width (thickness) 2.5-6.5 mm. The width of the seam when installing the slabs is determined by the thickness of the stop 11 (the seam width can be from 3 mm to 6 mm, depending on the recommendations of the slab manufacturer). This seam is necessary, for example, to drain surface water, and the minimum width of this seam of 3 mm prevents clogging with fine soil or dirt, which in turn ensures a long service life of the connecting element. The vertical stops 11 have a non-rigid (floating) fastening to the disk 4 and, if necessary, can be separated from the base when installing non-standard solutions, for example, in the case of laying the outer rows of floor covering slabs.

The design of disk 4 includes a central hole 12, which serves for additional fixation of the floor covering slabs using a self-tapping screw with a washer. Moreover, the washer is made of a composite of an upper metal part to ensure rigid fixation and a lower part made of rubberized plastic to prevent possible damage to the slabs by the metal part of the washer or the self-tapping screw. The self-tapping screw presses the floor covering slab against disk 4 and joist 3, thereby ensuring rigidity of the floor covering fastening to the frame. These fasteners reduce the risks of possible lifting of slabs by the wind and provide additional fixation in areas of increased loads (so that the slab does not rise from the raised floor under increased wind loads on the raised floor) or areas with installed equipment (possible vibrations).

The frame of the logs can be made of aluminum or its alloy, stainless steel, hard plastic (for example, polyetheretherketone) or other materials that meet the requirements of rigidity and strength.

Floor covering slabs can be made of ceramics (granite tiles, clinker, tiles, cotto), natural stone (granite, marble), sintered stone, tempered glass, polyvinyl chloride (PVC), composite materials or other materials that meet the requirements for floor coverings in the specific place of use of the floor covering.

The floor covering can be either heated (using heated plates, using liquid or air heating) or not.

The floor covering is installed as follows.

To form the surface of the floor covering, the slabs are installed on adjustable 1 supports using a connecting 4 element of the floor covering in the form of a disk with protruding vertical 11 stops located on the upper surface of the disk 4 in the form of a cross.

The required number of adjustable 1 supports are installed on the surface of the building base using construction fasteners. The number of adjustable 1 supports for the raised floor of the building base per 1 m2 is selected depending on the size of the floor covering slabs and the planned loads. A fastening 2 clip is mounted on each adjustable 1 support by snapping the lock connector on the lower side of the fastening 2 into the upper part of the support 1, allowing the upper part of the adjustable 1 support to be firmly connected to the joist 3, thanks to the grooves in the design of the joist 3.

The lag 3 is mounted on the prepared system of adjustable 1 supports with a step equal to the size of the slabs (e.g. 300×300 mm, 600×600 mm, 600×900 mm). The lag 3 is fastened by snapping the protrusions of the fastening 2 clip into the specialized grooves of the lag 3. After which the adjustable 1 supports are adjusted in height to achieve a tight fit of all supports 1 to the hard surface on which they are mounted, for example, to the roof covering or the main floor, and to achieve the 0 degree mark on the building level located on the lag 3 and between the two lags 3 (in turn for each lag 3).

After adjusting the height at the joints of the installed joists 3 using the snap fasteners 10 made on the lower side, a connecting 4 element of the floor covering in the form of a disk is mounted. Each disk 4 is installed on the joist 3 with a step equal to the size of the slabs, thus, the disk 4 is installed on the corner joint of four floor covering slabs. The floor covering slabs are laid over the connecting 4 element of the floor covering with the formation of a gap between the slabs due to the vertical 11 stops made on the upper surface of the connecting 4 element. Through the central hole 12 provided in the design of the disk 4, the floor covering slabs are fixed to the joist 3 using a self-tapping screw with a washer.
