Abstract

The cover material for application to balcony floors and/or stairs, additionally contains cement-bonded modified epoxy resin and an epoxy hardener, or polyurethane resin and a polyurethane hardener.

Description

The The invention relates to a Tenazzoboden and / or staircase according to the preamble of claim 1. Tenazzobeläge This type are already known (see pages 62 to 70 of the book "screed and Flooring in building construction "from Friedrich Eichler, published in 1955 in VEB Verlag Technik, Berlin) and are made using colored aggregates and white or gray cement in many Colors, executed. Tenazzotbeläge are durable, hardwearing, non-flammable and easy to care for. Your surface will sanded, partly also polished. Tenazzobeläge be in the main used in the commercial / decorative area of private and public buildings.

Tenazzobeläge be, in the current state of the art, either by means of a leveling layer on the raw concrete, or, with sufficient evenness, directly on the Raw concrete applied. For constructive reasons. dividing rails made of brass or plastic in the leveling layer or the raw concrete, from a size of more than 10 m2, technically necessary. Subsequently, will the mass reared by Tenazzokellen and compacted by rollers. at the earliest 2-3 days after the terrazzo can be ground with floor grinding machines become. It will be about 3-5 mm of the surface abraded. After different grinding processes, with different grits, The soil can be worked up to fine-tuning. Then you can choose different Care products are applied.

jointless Tenazzoböden be, according to the current state of the art. from quartz sands, cement, Color pigments, granite and / or marble sands and / or washed Sands, by the addition of watery Synthetic resin dispersions and an aqueous solution of a modifier for liquefaction produced. The mass for The Tenazzo floor is mixed in place and laid seamlessly. The terrazzo floors be after about 7 days with floor sanding machines ground. Subsequently can silicone impregnation or care products are applied (see Patent No. OE 44 29 1, 15 C1, method for the production of Tenazzoböden, patent holder Hofmeister industrial coatings GmbH 0: -84323 Massing, inventor Robell Schmöller).

The The problem with the Tenazzoboden is that it is due to the high water content in the cement-bound Tenazzomasse to cracks in the lining comes. The high water content results in a high building moisture as well long drying times. These lead at a time delay during further processing.

Another problem is the high weight / m ² . This results from construction height of approx. 10-50 mm as well as the usually used materials. For this reason, from today's state of the art Tenazzobeläge can only be used where the statics or the construction permits.

One Another problem is that the Tenazzobeläge produced today only conditionally underfloor heating suitable because they are not adequate due to their sealing Dimensions are diffusion-open. An application of underfloor heating leads i.d.R. to Cracks and blisters

One Another problem is that cement-based terrazzo saws from 25 mm do not allow the use of standard expansion joint profiles. That's why used non-cemented Tenazzobeläge contain i.d.R. solvent and lead mostly serious health damage.

Of the in claim 1 protection invention is based on the problem that tear-resistant Tenazzobeläge with a low water content and low weight without solvent-containing Aggregates also used today in underfloor heating can be.

This Problem is solved by the features listed in the protection claim 1 solved.

The particular advantages of the invention are that in the manufacture of terrazzo floors consisting of calcite and / or calcium carbonate and / or marble sand / granules and / or glass beads / nuggets and / or Color pigments and / or color pastes and / or CD splitter by a cement-bound, modified self-leveling Putty epoxy resin and epoxy hardener or polyurethane resin and Polyurethane hardener, be used and a seamless terrazzo floor is produced.

One The advantage is that mentioned by the use of the protection claim 1 solventless Synthetic resins and hardeners The water content is minimized, so that extensive sealing and Abklebemaßnahmen eliminated to prevent water from entering the structure can.

By the use of solvent-free synthetic resins as a binder in Terrazzobelag this can in a low layer thickness from 6 mm are produced.

Another advantage is that the floor covering can be used over underfloor heating because it is permeable to diffusion. The solvent-free binders improve elasticity and flexural strength of the terrazzo flooring. The terrazzo layer is hardened and walkable within a few days and can then be sanded with grinding machines in a dry grinding process.

When embodiment The invention will be a Tenazzoboden with the binder epoxy resin and harder and marble granules closer, described. For The manufacture of the jointless terrazzo floor is done on a cleaned Substrate made of tiles or natural stone or screed or concrete one Primer applied, which is made on the spot. The mixing ratio of Primer is 2 parts by weight of epoxy resin and 1 part by weight of epoxy hardener. The Primer is applied to the ground using a lambskin roller. On this primer is a quartz sand with a grain of 0.3 - 2.0 mm sprinkled before the primer is cured. The advantage of substrate preparation made of epoxy resin has excellent adhesion to the substrate. The subsequent Scaling with quartz sand serves the optimum adhesion of the jointless Terrazzobelages with the underground. In addition, by the epoxy resin primer the substrate solidifies in the uppermost zone. Within 24 Hours after applying the primer will be on the spot Mixed mass of marble granules in a thickness of about 6 - 8 mm seamless applied. This mass is compacted and smoothed. With Except for the construction expansion joints, this terrazzo floor can be seamless over any size Flat, to be laid. The next Days is the modified and colored filler by Rubber squeegee applied and peeled off. The next day is the seamless Surface treated in dry grinding process to fine grinding and sealed with epoxy or impregnated with wax.

The Invention provides opposite the Terrazzobelag a considerable cheapening of the laying, since due to the low layer thicknesses considerable time is saved in the laying of the terrazzo flooring can. additionally This results in a reduction of the grinding work, since the dry grinding process is used can be and must be sanded low Schlichtstärken.

One Another advantage is that the inventive, seamless, dispersion-open Teriazzobelag due to the low Schichstärken in renovations, Construction and conversion work and everywhere, where for static reasons only low installation heights possible are, can be used. Due to the low layer thicknesses and The aggregates mentioned can have a very fine terrazzo structure be achieved, which visually represents a special touch.

Claims (1)

Terrazzo floor or staircase consisting of calcite and / or calcium carbonate and / or marble sand / granules and / or glass balls / nuggets and / or color pigments and / or color pastes and / or CD splitter, characterized in that as a further supplement a cement-bound, modified self-leveling wax epoxy resin and epoxy hardener or polyurethane resin and polyurethane hardener, solvent-free used and a jointless, antistatic, slip-resistant, vapor-permeable tenazzo flooring is produced.
