Flooring installation system

The invention relates to a flooring laying system.

From the DE brochure of DA-TE Elemente Handels- und Produktions GmbH: Ceramic floor elements as a composite system

..., 3 l/2 leaflets, are floor elements made of porcelain stoneware 15

and epoxy resin with a glass fibre reinforcement. The

Floor elements have a size of 50 x 50 cm or 60 x cm, the thickness is 20 mm and the compressive strength is kg/m ² . For balconies, loggias, roof gardens, terraces, garden paths, arcades, pedestrian zones, the installation is carried out 20

on pedestals, mortar bags or even on gravel or sand. This ensures a drainage effect.

The disadvantage is that the pedestals or the mortar

bag the floor elements are only supported at their four corners 25

If the load on the floor elements is placed at a specific point in the middle, as when jacking up a car wheel, the floor elements can break. The use of mortar bags also increases the risk of the floor elements shifting. The pedestal supports, on the other hand, with their circular support discs, support the floor elements more steadily at their corners. The pins pointing upwards on the circular washers only serve to ensure that the gap between the floor elements is not too wide.

is exceeded. 35

EP 03 98 023 Al discloses a drainage element in plate

form for installation under moisture-exposed floors. It consists of plastic rigid foam bodies to which a cement-filled, hardenable synthetic resin mortar is added as a binding agent. The mass consisting of binding agent and plastic rigid foam bodies is poured into a mold. A reinforcing mesh can also be added. After the synthetic resin mortar has hardened, a drainage plate is available for further processing. Plastic angle elements are provided at the corners, which protect the corners and stiffen the element as a whole.

DE 195 14 820 Al specifies a mixture for building purposes which consists of a water-resistant binding agent and plastic rigid foam bodies, the proportion of which in the total volume is 70 to 90%. The mixture can be used to form a screed, to form building boards and to form building structures.

What these two well-known solutions have in common is that they have proven themselves and are key to progress in construction technology. However, they only provide partial solutions that still need to be perfected during the construction process.

A balcony construction is known from the DE brochure of the company SCHLÜTER: Balcony edges with Schlüter-BARA 09/96 p. l - 14. An adhesive is applied to a raw concrete slab with a slope, into which a profile rail with an edge profile is inserted on the edge. The

QQ An embossed drainage board is laid on top of the layer. A strip is then glued on top of which tiles are laid. The tiles are supported by trays filled with mortar.

The disadvantage is that the well-known balcony construction is very complex to assemble. In addition, water diffuses through the tiles and the tile joints under the tiles.

^ sen temporarily until it can be drained out via the drainage plates. If a cold snap occurs during this phase, the water held under the tiles freezes and breaks them off their base.

The task therefore arises to develop a flooring installation

system with the pedestals specified in the DE brochure: "Ceramic floor elements as a composite system..." that is easy and safe to install. It IQ should also be heat and sound insulating and safe and effective against the effects of water and frost.

According to the invention, this object is achieved by the features of claim 1.

The advantages achieved with the invention are in particular that the individual laying panels can be laid individually next to one another or with the help of the connecting plate bodies. The laying plate bodies secure

2Q not only ensures a constant joint spacing between the individual laying panels, but also holds them together and supports them so that they can withstand the required loads. Depending on the design, the laying panels are completely or partially surrounded by the frame beams of the frame.

The installation plate can be designed as a floor covering plate. In the case of a floor covering plate, the connecting eye bodies are set into the side opposite the covering body. This ensures that the floor covering plate is laid correctly along the joints.

A further embodiment of a laying plate is characterized by the features of claim 3. Here, the reinforcing frame ensures that the molded parts that are being formed are held in the correct position and in the correct manner. The surrounding frame can also protect the covering bodies from external influences.

Protect and lock against influences.

Furthermore, the frame can have at least one slotted recess on at least one frame beam on the outer surface opposite the grid body. These slotted recesses can be used as an installation aid by inserting plastic or metal plates into them and thereby holding the individual panels in one plane. The frame beams also enable the easy attachment of end profiles thanks to their slotted recesses, by simply inserting the insertion tool into them.

The covering body can be in the form of a plate or a web. Plate-shaped web bodies can be floor tiles, balcony tiles, parquet or the like. Web-shaped covering bodies can be fleece carpets or the like. These then cover at least one of the grid bodies and the molded part body that fills the grid elements. The use of differently shaped covering bodies allows the prefabricated laying plate to be covered with them. If tiles are used, they can be connected to one another with an elastic joint mortar. This effectively prevents chipping between one another. Damage to the outer edges of the tiles is effectively prevented by the frame beams. The use of web-shaped covering bodies, on the other hand, allows the laying plates to be partially or completely covered. The web-shaped covering body only needs to be limited to the frame beams on the outside of the balcony, terrace construction or the like. If, within the balcony or terrace construction, sheet-shaped coverings are used after plate-shaped coverings, the frame beams lying between them can take over the function of a finishing profile.

g g take.

The frame beams of the frame can be positioned opposite the grid

The longitudinal and transverse beams of the grid body have a frame overhang. This effectively protects the covering body to be laid. The frame overhang can correspond to the thickness of the covering body(s).

The molded body can be made of concrete, mortar and/or a mixture of recycled polystyrene and gypsum. The molded body can also be made of a mixture consisting of
- 50 - 90 vol.% plastic rigid foam bodies made of

. thermoplastic foams, e.g. foams made of polystyrene, polyvinyl chloride or the like,

. are rhombus-shaped and !5 . have a diameter between 0.5 and 50 mm and

- 10 - 50 vol.% water-resistant binder, which

. which surrounds the plastic rigid foam body after mixing,

. is pourable together with the plastic rigid foam body before 2Q agglomeration and . after hardening forms a matrix that has rhombus-shaped envelopes.

In individual cases, the following can be added: - 10 - 50 vol.% sand additives,

- 10 - 50 vol.% expanded concrete aggregates,

- 10 - 50 vol.% aerated concrete aggregates,

- 10 - 50 vol.% vermiculite additives.

2Q The water-resistant binder can be a synthetic resin mortar.

The synthetic resin mortar can be composed as follows:

- 40 - 95 vol.% hydraulic binder,

0 - 50 vol.% latent hydraulic binder,

- 0-20 vol.% filler,

- 0.1 - 5 vol.% hydrophobic agent

- O - 10 vol.% silicate,

0-10 vol.% dispersion powder

0-5 vol.% liquefier,

- 0-3 vol.% stabilizer.

Depending on the application and composition of the synthetic resin mortar, the following can be added:

- 0 - 5 vol.% reaction retarder,

- 0 - 5 vol.% setting accelerator, - 0 - 3 vol.% thickener,

- 0 - 5 vol.% foaming agent.

The composition and components of the latter mixture ensure a high drainage effect and high heat and sound insulating properties of the individual laying panels.

The longitudinal and/or transverse lattice beams and/or at least one of their outer surfaces can be at least partially inclined relative to the 2Q vertical. This ensures that the molded bodies hardened after agglomeration cannot fall out of the lattice elements.

The frame and/or the grid body can be made of plastic and/or metal. The use of plastic, especially rigid PVC (polyvinyl chloride), ensures high quality properties of the installation panels.

3Q The plate bodies used for laying the installation panels can have recesses. This allows the individual installation panels to be laid evenly with the covering.

gg At least one plate part body can be broken out of the plate bodies at predetermined breaking lines. A connecting body can be arranged on each plate body. The connecting

bodies are arranged at the same distance from each other. The plate body has four plate quarters as plate part bodies. The connecting body is arranged on each of these plate quarters as a cylindrical pin protruding upwards. Its height and diameter are such that it is compatible with the connecting eyes of the grid body. A complete plate body can be positioned in the middle under a laying plate or at the intersection of four laying plates. If a laying plate

IQ represents the outermost boundary of the balcony, terrace construction or the like, a quarter-plate body is positioned under it. In the area of the outer frame beams of two interconnected laying panels, two interconnected quarter-plate bodies are used as a half-plate body

A laying plate 1 is shown in Figs. 1 to 8.

As shown in particular in Fig. 1,
- a grid body 12 of
- surrounded by a frame 11.

The frame consists, as shown in Fig. 2, of four continuous frame members 11.1, 11.2, 11.3 and 11.4.

Instead of the continuous frames, frame beams that are interrupted along the length can be used. In addition, the frame 11 can have only one frame beam, two frame beams or three frame beams. These can abut one another or at least partially lie opposite one another. Each of the frame beams preferably has a length of 612 mm.

The grid body 12 consists of

- Lattice longitudinal beams 12.1, ... 12.&eegr; and

- Lattice cross members 13.1, ... 13.n”

The intersecting longitudinal and transverse lattice beams 12.1, ..., 13.1, ... enclose lattice elements 23.1, ... 23.in with the dimensions 50.5 x 50.5 mm. The longitudinal and/or transverse lattice beams 12.1, ... 12.&eegr;, 13.1, .... 13.&eegr; and/or at least one of their lattice beam outer surfaces 35, 36 are at least partially inclined relative to the vertical 37 (cf. Fig. 8).

Slotted recesses are made in the laying plate at the corners and approximately in the middle of the frame beams 11.1 and 11.3.

Slotted recesses 25.1 and 25.2 are arranged at the corner of the frame members 11.3 and 11.4.

The slot recess is shown in an enlarged view in Fig. 5 and Fig. 6. It extends over two grid elements.

Slotted recesses 26.1 and 26.2 are provided at the corner of the frame members 11.4 and 11.1.

A slot recess 27 is arranged in the middle of the frame member 11.1.

Slot recesses 28.1 and 28.2 are arranged at the corner of frame members 11.1 and 11.2 and slot recesses 29.1 and 29.2 are arranged at the corner of frame members 11.2 and 11.3.

A slot recess 30 is provided in the middle of the frame member 11.3.

All slot recesses extend, as with the

&iacgr;&ogr;

Slotted recesses 25.1 and 25.2 explained, via two grid elements 23.1, ... (see also Fig. 3 and 4).

In the area of the described slot recesses 25.1, ... and in the middle of the frame longitudinal beams 11.2 and 11.4, as also shown in Fig. 7 and 8, connecting eye bodies 14.1, 15.1, 15.2, 16.1, 17.1, 17.2, 18.1, 19.1, 19.2, 20.1, 21.1 and 21.2 are inserted.

^O ¹ ^ Four connecting eye bodies 22.1, 22.2, 22.3 and 22.4 are arranged in the middle of the laying plate 1. The connecting eye bodies 14.1, ... are, as shown in Fig. 7 and 8, cylinder bodies 32.1, 32.2, 32.4, ... . The cylinder bodies are formed on the longitudinal and transverse bars of the grid. They

! ₅ correspond in height to the height of the longitudinal and transverse lattice beams.

The entire installation plate is made of plastic, particularly hard PVC (polyvinyl chloride). Other plastics can also be used.

In Figs. 9 to 11 a connecting plate body 5 is shown.

The connecting plate body 5 consists of

- a circular plate body 51 and

- four connecting bodies 52.1, 52.2, 52.3 and 52.4 arranged on it.

go The plate body 51 is divided by predetermined breaking lines 55, 56 into four plate quarter bodies 51.1, 51.2, 51.3 and 51.4. The connecting bodies 52.1, ... 52.4 are each located on the 45° line of each plate quarter body 51.1, ... on a circle with a diameter of 113.14 mm. Circular openings on the circle are made in the plate body at equal distances between each other and opposite the connecting bodies 52.1, ... The plate bodies 51 themselves

have a diameter of 200 ram. On an inner circle of 180 mm, W-shaped recesses 54 are evenly spaced from one another, which are shown in detail in Fig. 11. They have a height of 12 mm, an upper width of 24 and a lower width of 15 mm.

The plate body 51 has a thickness of about 5 mm and is beveled at the edges by about 45°. The connecting bodies 52.1, ... protrude 15 mm above the plate body. They are also beveled at 45° at their upper end. The connecting bodies 52.1, ... are therefore compatible with the cylinder bodies 32.1, ... of the connecting eye bodies 14.1,

The construction of a balcony structure using the components described in the embodiment and the design of the installation plate 1 is explained below, in particular with reference to Figs. 1 to 12.

The connecting plate bodies 5 are laid out at a distance from one another on a prepared substrate and the prepared laying plates 1 are mounted. The substrate can be a walkway or a raw concrete slab onto which a sloped screed is applied. The slope of the sloped screed is directed so that it slopes towards a gutter. A masking layer is then stuck onto the sloped screed.

The laying panels l are perfected in that in go the grid elements 23.1, ... 23.&eegr; molded body 24.1, ... 24.&eegr; are arranged, which consist of a hardenable mixture.

The mixture consists of plastic rigid foam bodies and a water-resistant binding agent. The plastic rigid foam bodies have a sieve size between 01 and 50 mm. The plastic rigid foam bodies are characterized by

! foam bodies their diamond-like shape. The plastic rigid foam bodies make up between 70 and 90% of the total volume of the mixture. The plastic rigid foam bodies have a high compressive strength, high moisture and steam resistance, consistently low thermal conductivity, excellent shear strength, high tensile strength, optimal adhesive surface, low weight, homogeneous density, low thickness tolerances and easy processing. The mixture of plastic rigid foam bodies and the water-based

IQ permanent binding agents, which are designed as synthetic resin mortar and which are mixed with water, can be used optionally
10 - 50 vol.% sand aggregate
10 - 50 vol.% expanded concrete aggregates

10-50 vol.% aerated concrete aggregates

10 - 50 vol.% vermiculite additives
be attached.

The synthetic resin mortar (powder component) is composed as follows 2Q:

- 40 - 95 vol.% hydraulic binder,

0-50 vol.% latent hydraulic binder,

- 0-20 vol.% filler,

- 0.1 - 5 vol.% hydrophobic agent - 0 - 10 vol.% silicate,

0-10 vol.% dispersion powder

- 0-5 vol.% liquefier,

- 0-3 vol.% stabilizer.

In individual cases, the synthetic resin mortar can be optionally

- 0 - 5 vol.% reaction retarder,

- 0 - 5 vol.% setting accelerator,

- 0 - 3 vol.% thickener,
- 0 - 5 vol.% foaming agent.

The plastic rigid foam bodies and

^ the synthetic resin mortar, which is also described in detail, is mixed together in a mixer with the addition of water in the appropriate volume percentages. This mixture is then placed in the grid elements 23.1, ... After hardening, the synthetic resin mortar is placed around the plastic rigid foam body like a matrix. The matrix does not form a compact mass, but a structure with hollow bodies, capillaries, openings and casings, so that a drop of water falling onto the surface is easily absorbed and, in the case of larger

₁₍ -) water accumulations are also passed on. The water absorption and the throughput capacity of the molded parts 24.1, ... is extremely high. It is essential that water fed into the molded parts 24.1, ... does not lead to their destruction, since the plastic rigid foam bodies absorb all

!5 absorb volume changes and, in addition, the matrix is designed in such a way that the expansion forces that occur when the water changes from the liquid to the solid state of the ice are absorbed. It is also important that, as already described, the inclination of the lattice

2Q longitudinal and transverse beams 12.1, ... and 13.1, ... absorb the longitudinal expansions in such a way that the individual molded bodies 24.1, ... cannot fall out of the grid elements 23.1, ...

The covering body designated 34 is placed on the surface of the grid body 12 and the hardened molded body 24.1, ... The dimensions given as an example for the laying plate 1 can accommodate four balcony tiles or a walkway slab as the covering body 34. The balcony tiles

₃ Q or the walkway slab can already be laid on the finished laying slabs 1. In this case, it is advantageous to use an elastic mortar that absorbs gravitational forces that can occur during transport and act on the individual balcony tiles.

g ₅ can be accommodated without the edges of the tiles chipping off. The frame beams 11.1, ... 11.4 of the frame 11 ensure safe protection of the free outer edges even

! during transport. If the tiled installation plate 1 is subjected to strong impacts, the plastic grid beams absorb these forces.

When laying the laying panels l, the connecting bodies 52.1 of the connecting plate body 5 are pressed into the connecting eye bodies 14.1, ... It is essential that the plate bodies 5 ensure that all laying panels 1 are supported at the same distance from the already prefabricated subsurface. If high loads are to be expected, another connecting plate body 5 can be placed in the middle of each laying panel 1 and in the middle line between two adjacent laying panels l.

The connecting plate bodies 5 not only support the individual laying panels 1 in a force-fitting manner against the adhesive layer on the raw concrete slab. They also ensure that the layer of balcony tiles or paving slabs has the appropriate gradient so that rain hitting them is directed to a gutter or the like.

The arrangement of the individual connecting bodies 52.1, ... among each other ensures a uniform joint spacing between the laying panels 1. In addition, the individual laying panels l are held securely against displacement in such a way that the joint cannot only be reduced but also enlarged.

The slot recesses 25.1, ... of each installation plate 1 can be used to stabilize the connection between the individual installation plates 1 by inserting flat webs.

The particular advantage of the system components for balcony constructions and walkways or movement areas is that.

that they can be used both for the construction of new buildings and for the renovation of existing ones. The special design of the molded parts ensures that the existing moisture, whether from rain, snow, dew or the like, is drained away in such a way that the balcony tiles and other panels cannot come loose from their base. Rather, the molded parts and the intermediate joints, which are always kept at the same distance by the connecting parts 5, give the water the opportunity to drain away in a targeted manner so that the substructure under the tiles and panels is dry and, in particular, no frost damage can occur. The connecting parts 5 ensure that a heavy motorcycle can be jacked up on the balcony or terrace and vehicles can be parked on the panels without the individual balcony tiles or panels being damaged.
