BESCHREIBUNGDESCRIPTION
VERFAHREN ZUR HERSTELLUNG VON HAFTFLXCHEN BEI HOHER BEANSPRUCHUNG DER HAFTFUGE.PROCESS FOR THE PRODUCTION OF ADHESIVE SURFACES IN THE EVENT OF HEAVY DUTY THE ADHESIVE.
Die Verbindung unterschiedlicher Materialien, besonders bei feuchtem, senkrechtem oder überhängendem Untergrund ist oft schwierig, z, B, das Aufbringen von Kunststoffflächen auf Beton- oder Mauerflächen. Wenn für solche V#erbindungen ein hydraulisches Bindemittel (Mörtel) verwendet wird, sind Vorrichtungen erforderlich, die die Deckschicht, die aufgebracht werden soll, so lange festhalten, bis der Mörtel abgebunden hat. Das gleiche gilt bei der Verwendung von Kunststoffmörteln, die durch die Verbindung von zwei oder mehr Komponenten aushärten,bei der Anwendung auf trockenem Untergrund. Die nachstehend aufgeführten Maßnahmen vermeiden die Notwendigkeit aufwendiger Montagevorrichtungen und erhöhen besonders die Abriß- und Scherfestigkeit der Verbindungsfugen.The connection of different materials, especially in damp, vertical or overhanging subsurface is often difficult, e.g. application of plastic surfaces on concrete or wall surfaces. If for such connections a hydraulic binding agent (mortar) is used, devices are required which hold the top layer that is to be applied in place until the mortar has tied. The same goes with the use of plastic mortars that go through cure the joint of two or more components when applying on dry Underground. The measures listed below avoid the need for more complex work Assembly devices and especially increase the tear strength and shear strength of the connecting joints.
Elemente, die als Deckschicht für den Schutz von neuen oder reparaturbedürftigen Oberflächen benutzt werden und die bei ihrer Herstellung aus einer Matrix bestehen, die flüssig, teigig oder handfeucht geformt. wird, werden vor dem Abbinden oder Erhärten auf ihrer Rückseite mit einer im spanabhebenden Verfahren gewonnenen Mikrofaser beschichtet, Diese Mikrofaser besteht vorzugsweise aus Stahl oder Edelstahl. Die rückwärtige Beschichtung kann mittels eines Rüttelsiebes oder im Trockenspritzverfahren erfolgen.Items used as a topcoat for the protection of new or in need of repair Surfaces are used and which consist of a matrix during their production, those that are liquid, doughy or moist to the touch. will be before setting or Hardening on the back with a microfiber obtained in a machining process coated, this microfiber is preferably made of steel or stainless steel. the Back coating can be done by means of a vibrating screen or by dry spraying take place.
Im spanabhebenden Verfahren gewonnene Mikrofasern, vorzugsweise aus Stahl oder Edelstahl, sind kurze und mikrokurze dünne, starre Fasern, die unterschiedliche und unregelmässige Formen mit scharfen, gezackten, stark ausgefransten Begrenzungslinien der jeweiligen Oberflächen haben. Solche Fasern verzahnen sich besonders gut in einer unausgehärteten feuchten Matrix, wenn sie lose aufgeschüttet oder aufgespritzt werden. Bei nur'handfeuchter oder stark teigiger Matrix müssen die lose aufgebrachten Fasern leicht angedrückt werden. Beim Aufbringen dringt ein Teil der Fasern in die Oberfläche der Matrix ein und verankert sich dort wie ein. Zahndübel, so daß nach dem Aushärten der Matrix ein Teil der einzelnen Fasern fest in der Oberfläche der Matrix verankert ist, der andere Teil der Faser steht frei außen über. Ein weiterer Teil Fasern verhakt sich in den überstehenden Faserteilen ohne in die Matrix einzudringen. Dadurch entsteht auf der so behandelten Seite der Matrix ein dichtes, fest in der Matrix verankertes Faservlies.Microfibers obtained in the machining process, preferably from Steel, or stainless steel, are short and micro-short thin, rigid fibers that are different and irregular shapes with sharp, jagged, strongly frayed boundary lines of the respective surfaces. Such fibers interlock particularly well in an uncured, moist matrix if it is loosely poured or sprayed on will. If the matrix is only moist or very doughy, the loosely applied Fibers be pressed lightly. A part penetrates when it is applied of the fibers into the surface of the matrix and anchored there like a. Tooth dowel, so that after the matrix has hardened, some of the individual fibers are firmly attached to the surface the matrix is anchored, the other part of the fiber protrudes freely from the outside. Another Part of the fibers get caught in the protruding fiber parts without penetrating the matrix. This creates a dense, solid in the matrix on the side of the matrix that has been treated in this way Matrix anchored fiber fleece.
Die mit diesem Faservlies beschichtete Seite der ausgehärteten Matrix wird bei der Anbringung als Deckschicht mit Mörtel bestrichen. Die abzudeckenden Teile werden ebenfalls mit einer dünnen Mörtelschicht versehen, vorzugsweise mit mikrostahlfaserarmiertem Klebemörtel auf hydraur lischer Basis oder Kunststoffbasis. Dann läßt man die beiden eingemörtelten Flächen leicht anhärten, und zwar so weit, daß sie auch in senkrechter. Stellung nicht mehr fließen. Nun preßt man beide Teile aneinander, und zwar in solcher Weise,, daß sich keine Luftblasen bilden können.The side of the cured matrix coated with this fiber fleece is coated with mortar when it is applied as a top layer. The ones to be covered Parts are also provided with a thin layer of mortar, preferably with micro-steel fiber reinforced adhesive mortar on a hydraulic or plastic basis. Then the two mortared surfaces are allowed to harden slightly, to the extent that that they are also in vertical. Position no longer flow. Now press both parts to each other in such a way that no air bubbles can form.
Durch das vorbeschriebene Faservlies erfolgt eine sofortige feste Haftung zwischen der zu beschichtenden Fläche und der Abdeckung.The fiber fleece described above causes an immediate solid Adhesion between the surface to be coated and the cover.
Nach Aushärtung der Klebefuge, besonders bei zusätzlicher Verwendung von faserarmiertem Klebemörtel, entsteht eine faserarmierte Schicht, die eine besonders hohe Rißfestigkeit und eine besonders hohe Haftfähigkeit durch die Verankerung in der Abdeckschicht und eine besonders hohe Scherfestigkeit durch die Faserarmierung besitzt im Vergleich zu normalen Haftmörteln auf nicht faserbeschichteten Flächen.After the glue joint has hardened, especially when used in addition of fiber-reinforced adhesive mortar, a fiber-reinforced layer is created, which is a special high tear resistance and particularly high adhesive strength due to the anchoring in the cover layer and a particularly high shear strength due to the fiber reinforcement possesses in comparison to normal adhesive mortars on non-fiber-coated surfaces.
Weitere Untersuchungen haben ergeben, daß Elemente aus faserarmiertem Zement, mit einer Haftbrücke versehen, sich besonders als Dauerschalung für Betonkonstruktionen eignen, wobei sich z. B. bei Mikrostahlfasern, die wie vorbeschrieben in die Rück- oder Innenseite solcher Elemente eingebracht sind, eine vollflächige homogene Verbindung zwischen der Dauerschalung und dem später eingefüllten Beton ergibt.Further research has shown that elements made of fiber-reinforced Cement, provided with an adhesive bridge, is particularly suitable as permanent formwork for concrete structures are suitable, z. B. in the case of micro steel fibers, which, as described above, are or the inside of such elements are incorporated, a homogeneous connection over the entire surface between the permanent formwork and the later poured concrete results.
Diese Verbindung nimmt die sich aus Lasten ergebenden Scherspannungen und Biegezugspannungen voll auf. Gleichzeitig verhindert die vollflächige Mikrostahlfaserarmierung durch das Hineinragen der Fasern in die äußere Schicht des Füllbetons das Entstehen von Schwind- und Temperaturrissen in dieser Schicht.This connection takes the shear stresses resulting from loads and bending tensile stresses fully. At the same time, the full-surface micro steel fiber reinforcement prevents by the fibers protruding into the outer layer of the filler concrete of shrinkage and temperature cracks in this layer.
Die Beanspruchbarkeit einer armierten Haftbrücke aus Mikrostahlfasern wie vorbeschrieben kann noch erhöht werden, wenn man zusätzlich in die mit Mikrostahlfasern bestreute Fläche Draht elemente in entsprechender Form als Zusatzbewehrung in die noch nicht abgebundene Matrix der Schalung einbringt.The resilience of a reinforced bonding bridge made of micro steel fibers As described above, this can be increased if you also use the micro-steel fiber sprinkled surface wire elements in the appropriate form as additional reinforcement in the brings in not yet set matrix of the formwork.
In vielen Fällen kann eine ausreichende Haftung auch erzielt werden, wenn Haftbrücken aus Stahlfasern, Stahldrahtelementen jeder geeigneten Form, oder aus Vliesen oder Geweben jedes beliebigen chemisch geeigneten Materials bestehen, obwohl hier die Haftung nicht so vollflächig ist.In many cases, sufficient adhesion can also be achieved when adhesive bridges made of steel fibers, steel wire elements of any suitable shape, or consist of nonwovens or woven fabrics of any chemically suitable material, although the adhesion is not so extensive here.
