Definitions
- the invention is related to civil engineering field, that is related to finishing works on buildings, for covering level surfaces, specially floors, and can be classified in E 04 F 15/00 - Flooring, according to the International Patent Classification - seventh edition (IPC 7 ).
- slab-like floor coverings In practice, slab-like floor coverings must be installed in a way that they are mutually well connected, with minimum interspace, forming together perfect level surface. This surface must be able to support, in places, static and dynamic load, without raise and lowering down, in places, of one or more slabs, especially in relation to neighboring slabs in mutually opposite direction.
- the objective is to design level slab-like floor covering, which firmness and elasticity is lasting, but it can be, if desired, taken to pieces without destroying slabs.
- Technical problem to be solved is the construction of connecting elements that must link all slab-like elements (hereinafter slabs), with no remaining free edges, with the possibility of mutual additional taking slabs to pieces for partial substitution or removal.
- connecting elements An average skillful person must be able to install connecting elements in a simple way, without using special tool. After assembling, connecting elements must not be visible.
- the base on which slabs are installed, by means of such connecting elements, has not to be significantly leveled and smooth, while filling up of uneven spots that form holes between slab covering and supporting base, is not the issue this invention. Nevertheless, connecting elements should insure good mutual connection of slabs, even when such uneven spots appear.
- Contemporary solution for connecting floor slab elements anticipate variants with connecting elements but also various designs of slabs that are mutually connectable without connecting elements.
- the edges of some slabs have grooves on one side and tongues on the other, so you can get joint mutual fitting of edges into neighboring slabs, for example, with parquetry laths (FR 2746127 Al) and laminates (e.g. with hollow, longish elements as in EP 0783064 A).
- Most of the connecting elements are designed for installment under the crossing - the place where 4 neighboring slabs are joined.
- their primary function is floor cover leveling that is made of slab-like elements (e.g.FR 2761095), like ceramic slabs or floor stone slabs, so there is a mechanical regulation of the height of the particular connecting elements.
- connecting elements are individually permanently fixed to all 4 neighboring slabs, on their junctions (e.g. IP 11013203), or along whole connecting line of these slabs, in case that connecting element has a shape of a strip with holes.
- An interesting solution for installing and connecting slabs is a self- centered slab for production of prefabricated bearing surfaces with mosaic, ceramic slabs or framing glass (e.g. DE 3801805), where there is a net-like screen with compartments, where slabs are laid in precisely prepared hollows, and where they are arranged in such a way to be interconnected by glue.
- Every arm of the cross-shaped connecting element (1) has a shape of level flat tape whose cross-section thickness (a) is equal to the groove width (3) and the length of cross-section tape (b) is equal to half depth (b/2) of the groove (3), in which arms are placed.
- the length of some arms of cross-shaped connecting element (1) is equal to half length side (s/2) of one slab, so the groove in it (3) is completely filled when arms of two cross shaped elements (1) are connected.
- the cross-shaped connecting element can be made of metal, plastic or wood, but it is recommend to be of metal with necessary strength and elasticity, so that arms can properly stiffen two slabs to be connected. It is important that compatibility of arms and grooves in slabs is kept so as to get firm joint on inserting, as well as for mutual connecting cross shaped connecting arm elements on "tongue-groove" principle.
- Fig. 2 Method of connecting square slabs by using cross-shaped connecting element.
- Fig. 3 Presentation of accomplished joint of four slabs, and installing of next cross-shaped connecting element.
- connecting element is always cross shaped, with flat, long, thin lath arms. These arms should be inserted into grooves (3) all along slab edges (2) that are connected so as to get floor covering.
- cross-shaped connecting element (1) is presented with arms of the same length.
- Such connecting element is intended for connecting square like slabs, as shown in figures 2 and 3.
- the opposite arms of cross-shaped connecting element are of different shape endings: on one side there is a short tongue-"feather-edge element” (4) of reduced arm thickness, to approximately 1/3 of the width, shown in detail "A”, and on the other side there is a hollow - " groove "(5) compatible with "tongue” thickness (d) and its length, as shown in detail "B".
- the condition for using this invention comprising a cross-shaped connecting element (1) is that every slab (2) which has to be connected with the same such slab has grooves (3) made along the center of each of its 4 sides. The depth of this groove has to be equal to half arm width of cross- shaped connecting element (1).
- One cross-shaped connecting element should link 4 identical slabs that have to be installed one by one on arms of cross-shaped connecting element.
- the assembling starts (phase 1, figure 2) with placing the first cross-shaped connecting element (1) into grooves at the angle of a slab (2). Slight manual blows can perform this with rubber hammer on the lateral sides of arms of connecting element (1). Both mutually vertical arms of connecting element (1) have to be placed into grooves (3) completely, whereby it is fixed exactly at the corner of a slab (2), while its arms are sticking out from the edge of the slab with the half of its width.
- Net obtained from joined cross-shaped connecting elements should represent design solution by which increased solidity of slab-like covering is obtained, e.g. on the floor. Therewith, joint leveling of 4 slabs is surely obtained. Existing uneven spots under such formed covering don't represent major problem any longer as the covering in its entirely is now solid whole. Its elasticity depends only of material elasticity from which connecting elements are made.
- Connecting element is equally suitable for installmg slabs indoor and outdoor.
- the base on which the slabs are installed by use of cross-shaped connecting elements, must be level. After the base is covered with slabs, it is possible to use such slab surface immediately, since no materials that need to dry up or stiffen are used.
- connecting elements are not visible from upper finished level surface, as they are hidden in grooves of slab edges, their esthetic effect is not relevant, so they can be made of the cheapest material in any color. It is important that arms of cross-shaped connecting elements are undamaged and without additional protuberances, especially on their ends. That is important so as to achieve firm joint on "tongue-groove" principle, so that thin lath shaped arms could have suitable place in the grooves of slab edges.
