Abstract

The system has two different standard expanded polystyrene (EPS) plates placed in table-shaped plates (1), where the EPS system records dimensions between the table-shaped plates. Plastic nails are to attach to the EPS plates. Corners of EPS shaped concave-convex connection parts are positioned to the EPS plate. A cavity is formed in each corner of a flat system board. An opposite convex part is formed on a leg of a table-shaped system board. A supporting surface is provided with the table shaped plate. Multiple continuous grooves are formed in a flat plate (2).

Description

EPS floor plate system for application on flat (concrete ·) floors and under cement screeds, for installation over installations and piping systems mounted on the flat (concrete) floor.

The invention relates to an EPS floor plate system for use on flat (concrete) floors and under cement cover floors, for placement over installations and pipe systems mounted on the flat (concrete) floor.

The system consists of two different standard EPS system plates that are laid together in a special pattern and form a subfloor for the cement screed. In addition, when used with standard EPS system plates, the number of "table-shaped" EPS system plates with "legs" is limited to approximately 20% of the total number of EPS system plates.

The size of the EPS system plates measured at the top is between 400 x 400 mm and 800 x 800 mm, but does not determine the invention. The height of approximately 15 250 mm and the thickness of the plates can also vary slightly. The height is adjusted to the installation of complete installations, such as sewerage, ventilation ducts, etc. Depending on the rigidity and strength of the EPS, the plate thickness of the "deck" is possible in combination with a reinforcement plate.

The EPS system board types can be described as follows:

Plate type 1: The standard "table-shaped" EPS system plate.

The standard "table-shaped" plate is equipped with "legs" so that it can be placed over the installations. This plate is specially designed so that it can be laid around the "flat" plate.

25 Plate type 2: The standard "flat" EPS system plate

The standard "flat" plate is laid on the "legs" of the "table-shaped" plate. In addition, various desired sizes can be realized between the "table-shaped" plates with the help of newly sawn or special versions of the standard "flat" plate.

The "legs" can, if desired, be kept "separate" from the deck of the "table-shaped" plate and mounted at the mounting location below the deck of the "table-shaped" plate.

The stability and stiffness of a floor consisting of the EPS floor plate system can be increased by applying connections between the EPS system plates. The connection between the plates can be achieved, inter alia, by using special system plate "staples", loose system plate "nails" and / or with a hollow-ball connection in the corner of the EPS system plate. make an additional support surface / rebate on the side of the plates.

At the top, the EPS system panels can be provided with various finishes for installing underfloor heating pipes. This also includes the use of a special metal heat conduction and pressure distribution and reinforcement plate with a circular course of the underfloor heating pipe slots. These circular slots 5 offer the possibility to lay the floor heating pipes through the EPS floor plate system in any desired pattern and also to conduct as much heat as possible to the top of this metal plate. Extra cavities can be made in the middle of the circular parts of this metal plate, as a result of which a good adhesion with the cement screed and extra stiffness of the plate in combination with the cement screed is created. The metal plate thereby acts as a kind of reinforcement and increases the rigidity of the system.

The invention will be further elucidated on the basis of an exemplary embodiment of the EPS floor plate system 15 shown in figures

Figure 1 shows schematically the floor system in section with standard plates. The "table-shaped" plate (1) stands on the flat (concrete) floor (3) and is placed over the pipes (4). The "flat" plate (2) lies on the "table-shaped" plates (1). the cement screed is applied to the plates (5).

Figure 2 schematically shows the floor system in cross section with the “flat” plate made to the smallest size (6).

Figure 3 shows the "table-shaped" plate (1) three-dimensionally. The possibility of keeping the legs loose is also indicated.

Figure 4 schematically shows the floor system from above, clearly showing that the number of standard “table-shaped” plates (1) is approximately 20% of the total number of system plates. In the figure, these are additionally marked with the help of a cross. quantity of 30 standard "flat" plates (2) is approximately 80% of the total number of system plates

Figure 5 shows the connection possibility between the two plates by means of a metal system plate “not” (20).

Figure 6 shows an elaboration of this metal system board "not". The "not" is provided with special stiffening baffles (21), which make the "not" stronger

Figure 7 shows a coupling possibility of the plates by means of a hollow-sphere connection (12) 40 3 formed in the EPS

Figure 8 shows a coupling possibility of the plates by means of a plastic "nail" (13). Holes are included as standard in the corners of the plate.

Figure 9 shows the effect of this plastic “nail” (13). This "nail" is provided with 4 ribs with a serrated edge that counteracts pulling out of the smashed "nail".

Figure 10 shows a support connection in the side of the plates (14). With this support connection, the "table-shaped" plate (1) is provided with an additional support surface designed in EPS. In the "flat" plates (2), this support surface is recessed into a continuous or non-continuous rebate.

Figure 11 shows the "table-shaped" plate (1) with a support connection designed in the EPS plate in the side three-dimensionally. The "flat" plate (2) is also indicated in cross section with a continuous support frame.

Figure 12 shows diagrammatically in cross-section an example in which the upper side of the EPS plates is provided with foil (8) for mounting underfloor heating pipes (7) in the screed (5).

Figure 13 shows diagrammatically in section an example in which the upper side of the EPS-20 plates is provided with slots (9) for floor heating pipes (7). Circular cavities (11) are made in the EPS plate that provide extra strength and stiffness in combination with the cement screed.

Figure 14 shows diagrammatically from above an example in which the upper side of the EPS plate is provided with slots (9) for underfloor heating pipes (7). The circular pattern is clearly visible in the figure. Circular cavities (11) are made in the EPS plate that provide extra strength and stiffness in combination with the cement screed.

Figure 15 shows, viewed from above, the metal pressure distribution, heat conduction and reinforcement plate (10) glued to the EPS with circular floor heating pipe slots (9) and the circular cavities (11).

Figure 16 shows a cross section of the metal pressure distribution, heat conduction and reinforcement plate (10) glued to the EPS with circular floor heating pipe slots 35 (9) and circular cavities (11) which, in combination with the cement-bonded screed (5), provide additional rigidity to the Give EPS plate (2). The extra circular cavities (11) have a dovetail form.
