Wölte, Ulrich, Schüttenrode 16, 48282 Emsdetten "Construction element with lightweight screed base layer"

The innovation concerns a component according to the generic term of

Claim 1.

In practice, building elements in the form of tile panels are known, in which a concrete base layer is covered with a surface layer of tiles. A panel of about

In practice, a 50 x 50 cm size weighs around 20 kg, so that the large-scale installation of such building elements, especially without mechanical support, represents too great a physical strain for many do-it-yourselfers.

The innovation is based on the task of improving a generic building element so that it can be easily handled and installed even by laypeople without special tools.

This problem underlying the innovation is solved by a component having the features of claim 1.

The use of lightweight screed is known from practice.

This is a spreadable mass consisting of

a granulate and an adhesive, whereby in practice foamed polystyrene is used for the granulate. The associated adhesive, e.g. tile adhesive, on the one hand connects the granulate bodies to each other and on the other hand creates a strength after setting, which allows the application of a

Floor covering on this lightweight screed is permitted.

The lightweight screed is used in rooms and is usually spread over the entire room area. The floor made with such a lightweight screed therefore represents a

A building element manufactured in a room and firmly connected to the room, which cannot be handled separately.

In other words, the innovation proposes to design the building element as a layable panel, i.e. with a correspondingly clean

edges that allow several similar panels to be joined together so that the lightweight screed does not have to be processed on site. Furthermore, a walkable surface layer should be provided so that the finished floor can be created immediately by laying the individual panels.

By using lightweight screed as a base layer or in the base layer, initial tests have shown that a floor slab can be produced that weighs about half as much as a floor slab with a base layer made of concrete, so that the new material can be handled easily and without any problems.

appropriate components.

Advantageously, the base layer can have a surface layer in the form of tiles glued to the base layer.

In this way, the production of tiled floors is easy

This is quick, uncomplicated and very time-saving. Compared to similar tiles with a concrete base layer, the new technology allows tiles to be half as heavy, which means the installer is much less physically burdened.

In particular, if the tiles on the individual tile panels are already grouted, no subsequent finishing work is required after laying the tile panels, so that tiled surfaces can be created quickly and easily, even for laypeople

can be.

As an alternative to the tiled surface, the base layer can be provided with a plastic coating, so that non-slip surfaces in a wide variety of designs can be easily

floors that can be manufactured using koren.

Due to the weight savings, tiles or floor panels can be used in accordance with the new standards, particularly in the area of old building renovation, where the support structure under terraces or balconies often prohibits high weight loads.

In addition, the new construction elements can be used to create impact sound-insulating floors due to the dampening effect of the expanded polystyrene granulate. In particular, this facilitates the formation of impact sound-insulated stairs.

pen in multi-family houses or administrative buildings if the structural elements are designed as the tread or joint of a stair step or angled as structural elements that simultaneously represent the tread and joint of a stair step.

The weight advantages of lightweight screed can, when used outdoors where the surfaces are exposed to rain, lead to the building elements floating. This is particularly the case if the walking surface is not formed by heavy tiles, but by light

Tiles or a plastic coating, this buoyancy behavior of the lightweight screed can be counteracted by adding heavy particles, such as sand.

The sand penetrates into the gaps of the granular material and

This also increases the strength of the lightweight screed through the different grain sizes in a kind of "concrete effect". This ensures that even when using tiles that are comparatively heavy compared to the base layer, the building element is not damaged during handling.

is shatterproof during installation and subsequent use.

Furthermore, the resistance of the structural element, e.g. the resistance to breakage, can be increased by fibers embedded in the base layer, which also

improve the bond within the base layer.

Depending on the requirements for recyclability and sound insulation, different materials can be used as granules in the base layer. In addition to the foamed polystyrene known from practice, expanded clay, pumice or similarly light materials, especially natural

natural mineral substances are used.

Examples of the innovation are explained in more detail below using the drawing. 10

contains components in accordance with the innovation.

In Fig. 1, 1 generally designates a building element which has a base layer 2 which is essentially made of a lightweight screed, whereby this lightweight screed, however, is made of embedded granulate of very small grain size, as in

for example sand, as well as embedded fibers, it is low in buoyancy in terms of its weight and particularly resilient in terms of its strength and durability.

Tiles 3 are glued to the base layer 2 using an adhesive layer 4. The tiles are grouted with mortar 5 so that a walkable and finished floor design can be achieved immediately by laying the building elements 1.

The building elements 1 are advantageously laid in a bed of sand or gravel. In this way, the base layer 2 can be kept so thin that the weight of each individual building element 1 is kept low and facilitates easy processing. Since the base layer 2 is permeable to water,

laying of the building elements 1 on a stilt foundation

or a similar foundation with drainage effects is not required, since the water is drained through the base layer 2 into the sand or gravel foundation.

In Fig. 2, a staircase 6 cast from concrete is shown, in which elongated structural elements 1 are designed both as a butt and as a tread of the staircase and are attached to the concrete staircase 6. The supporting layer 2 has impact sound-absorbing properties, particularly when using granulate made of foamed polystyrene, so that an excellent

Sound insulation of staircase 6 is achieved.

The building elements 1 according to Fig. 2 are particularly slip-resistant because the supporting layer 2 is not provided with tiles, but with a plastic coating 7, whereby by selecting

of the plastic or by selecting embedded particles and a corresponding surface roughness, the desired slip resistance can be achieved. When the front edges of the steps are loaded, the components 1 are subjected to strong pressure, which can be

commercially available lightweight screed for the base layer 2 could lead to the breaking out of particles of the base layer 2. By incorporating sand and/or fibers, the base layer 2 can be sufficiently resistant even for the use of the building elements 1 as a joint or tread of a staircase.

stable and durable without losing the impact sound-absorbing properties of the component.
