Raised floor panel

The innovation relates to a raised floor panel with a load-bearing Base plate, in particular from a ujanne-shaped body Material with high tensile strength and high modulus of elasticity, e.g. Sheet steel, and a tub filling made of a material with low Tensile strength and low modulus of elasticity, e.g. Anhydri '.., furthermore with a cover layer attached to the base plate, whereby the base plate all-round butting edges that are flush with their upper side, E.g. on an outwardly protruding peripheral flange of the i-shaped Body.

Such a double floor panel is known from DT-PS 2 004 101 become. The previously common white cover layer used for this raised access floor panel consists of a carpet or a plastic sheet. Recently, however, for a variety of reasons also raised floor tiles v / obtained, the coverings made of natural or artificial stone or have ceramic tiles. Raised floors with such coverings However, naG must be able to be purified, the problem being occurs because, on the one hand, the joints between the individual double floor panels must be properly sealed around the space below the raised floor to be kept absolutely dry, and on the other hand that the advantages of a raised floor are retained, namely floor panels if necessary to be able to take out at various points of the raised floor and reinsert it in a sealed manner. It is of great importance that ceramic tiles and the like have relatively large dimensional tolerances

According to the innovation, the above-mentioned problem with a raised access floor panel of the type referred to above is solved by the fact that the Covering existing natural or artificial stone or ceramic material with its peripheral edge evenly slightly from your stubborn edges The base plate is set back in order to create joints between the coverings of adjacent raised access floor panels on StoG «to accommodate a sealing joint filler (e.g. permanently elastic putty or the like). Such raised access floor panels can be advantageous with one another laid as desired, soiuie individually removed from the raised floor and reinstated bzm. be replaced. To remove a raised access floor panel, it is only necessary to cut open the joint filler (permanently elastic putty or the like) in the joints concerned and to be renewed when inserting the double fountain plate. On off Raised floor panels according to the innovation laid floor, the joints of which are sealed by a joint filler, can also easily n ^ Q can be cleaned without the risk of moisture entering the cavity below the raised floor, which comes from a wide variety of known reasons.

If, according to one embodiment of the innovation, the top covering of a raised access floor plate is composed of several stone elements and ceramic tiles, which are separated by cross-shaped, symmetrically arranged joints, the width of which is that of the joints between the top coverings corresponds to adjacent raised access floor panels that are butt-jointed A visually flawless double floor is also achieved, as there is a uniform joint grid and the same joint widths over the entire floor, which is made up of raised floor panels according to the innovation.

The innovation is then based on the drawings of an implementation

example explained in more detail. Show it:

FIG. 1 shows a sectional view at the joint of double floor panels

according to the innovation above a footrest for this} FIG. 2 is a plan view of the arrangement shown in FIG. 1; FIG. 3 is a perspective view of a section from a Double floor that opens and in the area of a footrest

of floor panels of the innovation is constructed in accordance with and FIG ü α ne plan view of a portion of a raised floor similar to FIG. 3

Have the double floor panels 10 shown in Figures 1-4 all have the same square plan and are therefore in one predetermined grid with their corners on footrests 11 can be laid, the are in turn placed on a bare floor 12. You footrests are known to be adjustable in height in order to level the double floor panels 10 to enable bziu. around unevenness of the bare floor 12 to be able to compensate. The raised floor panels 10 can be with one another laid as required, individually taken out of the raised floor and reinserted and / or grounded to make the space below the raised floor accessible close.

Each raised floor panel 10 usually has a supporting base plate 13 to which a covering 14 is attached, e.g. glued on, which is made of natural stone, Artificial stone or ceramic tiles.

According to the embodiment, each supporting base plate includes 13 a trough-shaped body 15 made of, for example, sheet steel with a filling from z.3. Anhydrite. The male-shaped body 15 usually has an outward direction protruding Utnfangsflansch 16 3uf, and the outer edges of this circumference

FangsflanschBs form abutment edges 17, which are cut with high accuracy to the desired grid size. The raised floor panels 10 laid on the footrests 11 therefore only touch at these joint edges 17. The cover 14 made of natural stone, artificial stone or ceramic tiles is set back with its peripheral edge by a slight distance A from the 5toG edges 17 of each base plate 13. As a result, when the raised access floor panels 10 are laid butted, joints with a width of 2 ^× A are created, which are sealed with a joint filler 18, for example a permanently elastic putty. If a double floor panel 10 is to be removed if necessary, the permanently elastic putty only needs to be cut open and replaced when the double floor panel is inserted.

According to FIGS. 3 and h , the top covering of each double floor panel 10 is composed of four stone elements or ceramic tiles 14a of the same format, each of which is cross-shaped and ~. symmetrically arranged joints 19 are separated from one another. The width of this joint 19 corresponds to that of the joints between the coverings of adjacent double floor panels 10 installed in a butt joint. The joints 19 are expedient with the same joint filler. permanently elastic putty like the joints between adjacent raised floor panels 10, so that a uniform, visually appealing network of joints is achieved.

A possible height tolerance due to manufacturing inaccuracies in the case of the deck lining, which is not covered by the rough-elastic putty «Can be grounded, can be compensated by providing the finished raised access floor panel with so-called compensating pieces only at their support corners, which can be ground down individually in this way», that accurate panel heights are obtained.
