DE102011001620A1 - Wall element i.e. wall panel, for use as drain layer in inner wall of cellar room of building, is made from gravel composite, plastic granule composite and polyurethane or urea spray coating, where gravel composite comprise bonding agent - Google Patents

Abstract

The element (100) i.e. wall panel (5), is made from a gravel composite (3), plastic granule composite (2) and a sealing polyurethane (PU) or urea-spray coating (40). The gravel composite comprises a PU bonding agent and dried gravel with a grain size of 0.7-1.2 mm. The PU bonding agent comprises a polyol component with additives and diisocyanate in a proportion of about 5-10 weight percent. The granule composite is formed from recycled acrylonitrile butadiene styrene (ABS) and the PU bonding agent in a proportion of 10-20 weight percent.

Description

The invention relates to a wall element which is used as a wall panel in buildings, in particular in basements, as a drain element.

The state of the art is with the Utility model G 93 10 120.1 a "suction nozzle for the suction of dust and / or liquids" known, which consists of a cup-shaped suction nozzle provided with a suction body, which encloses a limited by an elastic seal suction chamber. A sealing between the surface to be suctioned and the suction cup is effected via rubber lips or similar sealing elements in order to guide the liquid to be absorbed into the effective area of the suction line.

Furthermore, a method for aspirating liquids from the US 5,032,184 known, wherein a round plate with lower suction channels with connection of a pump system is available.

In utility model DE 202 14 931.5 "Flachsaugmatte for complete suction of liquids, especially on flat surfaces, in conjunction with a pump of known design" is a Flachsaugmatte shown, which consists of a rubber material and is present with a connected pump device. In this case, suction channels are present in a lower part of the pump mat, which causes aspiration of the liquid by suction via the pump device.

Furthermore, a technical solution "Filter network" DE 10 2008 060 723 discloses a filter unit for the purification of fluids, filter systems composed of a plurality of such filter units and the use of the filter unit or the filter systems for filtering sludge and floating algae from water or for the purification of gases.

The disadvantages of all mentioned devices and documents of the prior art are given by the fact that in each application of the technical solutions described a suction of the liquid with contained residues, such as dirt, stones and other large-grained materials is performed, and thus the extracted liquid has a high Pollution degree has.

The aim of the invention is to find a wall element as a wall panel in buildings, especially in cellars, in the form of a drainage layer, which can be produced by simple economic means.

The object of the invention is to provide a wall element as a wall panel in buildings, especially in basements, as a drainage layer, wherein the wall element is produced in a three-stage process and by its composition meets the chemical and physical requirements and is executable in different designs.

According to the invention the object is achieved in that the patent claim 1 is realized with its subclaims.

• – dass ein Wandelement aus einem Kunststoffgranulat-Verbund, einem Kies-Verbund und einer dichtenden PU-/Urea-Sprühbeschichtung besteht,
• – dass der Kies-Verbund aus getrocknetem Kies in der Körnung 0,7 bis 1,2 mm mit einem Polyurethan-Bindemittel, bestehend aus Polyolkomponente mit Zusatzstoffen und Diisocyanat mit einem Anteil von ca. 5 bis 10 Gew.-%, hergestellt ist.
• – dass der Kunststoffgranulat-Verbund vorrangig aus ABS- oder PU-Rezyklat mit PU-Bindemittel mit einem Anteil von ca. 10 bis 20 Gew.-% vermengt wird und auf den Kies-Verbund aufgetragen ist,
• – dass nach Aushärtung des Kunststoffgranulat-Verbundes das Wandpanel direkt auf die Gebäudeinnenwand montiert und mit einer PU-/Urea-Sprühbeschichtung wasserdicht versiegelt ist.

A wall element in the form of a wall panel was developed in this way

• A wall element consists of a plastic granulate composite, a gravel composite and a sealing PU / urea spray coating,
• - That the gravel composite of dried gravel in the grain size of 0.7 to 1.2 mm with a polyurethane binder, consisting of polyol component with additives and diisocyanate in a proportion of about 5 to 10 wt .-%, is prepared.
• - that the plastic granulate composite is mixed primarily of ABS or PU recycled material with PU binder in a proportion of about 10 to 20 wt .-% and is applied to the gravel composite,
• - After hardening of the plastic granulate composite, the wall panel is mounted directly on the building inner wall and sealed watertight with a PU / urea spray coating.

Advantageous and / or preferred embodiments of the invention are the subject of the dependent claims.

The present invention will now be explained in more detail without limitation and only for the purpose of illustration. For this purpose, figures are given in the embodiment, which define in particular the various embodiments of the filter material in its design.

In the 1 a wall element is shown.

The invention relates to a wall panel that is used in buildings, especially and basements, as a drain element. In 11 the basic structure is shown. To the building wall 100 become the wall panels, consisting of plastic granulate composite 02 , Gravel composite 03 and sealing PU / urea spray coating 40 appropriate.

The at the building interior walls intermittently 05 built wall panels are used for the drainage (drainage) of moisture, for example, by rising groundwater or flood can occur on basement walls. The subsequently applied, seamless PU / urea spray coating 40 keeps the interior dry.

Dried gravel with a grain size of 0.7-1.2 mm is mixed with a polyurethane binder consisting of polyol component with additives and diisocyanate in a proportion of about 5-10 wt .-%, in a container / mixer drum. In a separated form, the gravel / binder mixture is filled and slightly compacted.

After hardening of the gravel / binder mixture to a gravel composite 03 is a plastic granules, primarily ABS or PU recyclate, mixed in the same way with the PU binder in a proportion of about 10-20 wt .-%, on the gravel composite 03 applied and slightly compacted.

After hardening to a plastic granulate composite 02 The wall panel can be mounted directly on the building's interior wall and with the PU / urea spray coating 40 sealed watertight.
