Description

Die Erfindung bezieht sich auf ein Abschalelement für eine Dehnfuge der im Oberbegriff von Anspruch 1 erläuterten Art.The invention relates to a Abschalelement for an expansion joint explained in the preamble of claim 1 Art.

Ein solches als wieder verwendbare Schalung ausgebildetes Abschalelement ist aus der DE 93 11 710 U1 bekannt. Dort werden die Sperrmatten auf spitze Dorne aufgesteckt, die an den Schaltafeln aufgebracht sind. Diese Bauweise ist für verlorene Schalungen ungeeignet, weil die Sperrmatten vor dem Einbau der Schalungen verlorengehen können.Such as reusable formwork trained Abschalelement is from the DE 93 11 710 U1 known. There, the barrier mats are attached to sharp spikes, which are applied to the formwork panels. This design is unsuitable for lost formwork, because the barrier mats can be lost before installing the formwork.

Abschalungen, die sich auch für Dehnfugen eignen, sind auch aus der DE 94 15 265 U und der DE 201 18 098 U bekannt. Diese bekannten Schalungen sind auch als wieder verwendbare Schalungen ausgebildet, wobei nach dem Vergießen des ersten Betonierabschnittes das Abschalelement entfernt und auf der dadurch freigelegten Betonoberfläche eine Dehnfugenverfüllung in Form einer Sperrmatte befestigt wird. Anschließend wird der zweite Betonierabschnitt gefertigt. Wieder verwendbare Abschalelemente sind jedoch relativ arbeitsaufwändig. Der Versuch einer Verwendung verlorener Abschalelemente auch zum Abschalen von Dehnfugen scheiterte daran, dass bislang keine befriedigende Möglichkeit gefunden wurde, die Sperrmatte bei Verwendung eines verlorenen Abschalelementes in der Fuge zu befestigen. Eine Befestigung der Sperrmatte mit den üblichen Schalungsbefestigern, wie beispielsweise Rödeldraht oder Kabelbinder oder mittels Aufsteckdornen, ist aufgrund bauaufsichtlicher Bestimmungen, die besagen, dass bei (bestimmten) Dehnfugen kein die Fugen überbrückendes und an der Außenseite der Sperrplatte vorstehendes Befestigungselement zulässig ist (beispielsweise wegen Korrosionsgefahr), nicht immer möglich.Shuttering, which are also suitable for expansion joints, are also from the DE 94 15 265 U and the DE 201 18 098 U known. These known formworks are also designed as reusable formwork, being removed after the casting of the first concreting the Abschalelement and on the thus exposed concrete surface a Dehnfugenverfüllung is attached in the form of a barrier mat. Subsequently, the second concreting section is manufactured. Reusable Abschalelemente are relatively laborious. The attempt to use lost Abschalelemente also for Abschalen expansion joints failed because so far no satisfactory way was found to attach the barrier mat using a lost Abschalelementes in the joint. An attachment of the barrier mat with the usual formwork fasteners, such as wire or cable tie or arbors, is due to building regulations, which say that in (certain) expansion joints bridging the joints and on the outside of the locking plate protruding fastener is permitted (for example, due to risk of corrosion ), not always possible.

Aus der DE 199 05 691 A1 ist eine verlorene Schalung für Dehnfugen ohne Sperrmatten bekannt.From the DE 199 05 691 A1 is a lost formwork for expansion joints without barrier mats known.

Der Erfindung liegt somit die Aufgabe zugrunde, ein verlorenes Abschalelement zum Ausschalen von Dehnfugen bereitzustellen.The invention is therefore an object of the invention to provide a lost Abschalelement for stripping expansion joints.

Die Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.The object is solved by the features specified in claim 1.

Durch die Erfindung wird ein Abschalelement geschaffen, das im Beton verbleiben kann und trotzdem eine allen baulichen Richtlinien genügende und einfache zu handhabende Einbaumöglichkeit für eine Sperrmatte bietet. Das erfindungsgemäße Abschalelement wird als einbaufertige Einheit bereitgestellt.The invention provides a Abschalelement is created, which can remain in the concrete and still offers all construction guidelines sufficient and easy to handle installation option for a barrier mat. The formwork element according to the invention is provided as a ready-to-install unit.

Vorteilhafte Weiterbildungen sind den Unteransprüchen zu entnehmen.Advantageous developments can be found in the dependent claims.

Wenn die Dehnfuge Brandschutzrichtlinien genügen soll, so wird ein nicht brennbarer oder schwer entflammbarer Kleber eingesetzt.If the expansion joint is to comply with fire protection guidelines, a non-flammable or flame-resistant adhesive is used.

Ein bevorzugt verwendeter Kleber zum Befestigen der Sperrmatte auf der Schalungstafel ist ein Kleber auf Zementbasis, der sich sowohl für brandgeschützte Dehnfugen als auch für Anwendungszwecke eignet, wo ein Brandschutz nicht unbedingt erforderlich ist.A preferred adhesive used to secure the barrier mat to the formwork panel is a cement-based adhesive that is suitable for both fire-resistant expansion joints and applications where fire protection is not essential.

Das Abschalelement ist bevorzugt mit einer Aussteifung versehen, die die unterschiedlichsten Aussteifelemente enthalten kann.The Abschalelement is preferably provided with a stiffener, which may contain a variety of Aussteifelemente.

Die Fugenbandhalterung kann entweder nur durch einen Spalt zwischen den Schaltafeln gebildet werden, ist jedoch bevorzugt als eigenständiger Fugenbandhalter ausgebildet, der in irgendeiner Weise mit den Schaltafeln verbunden ist.The joint tape holder can either be formed only by a gap between the formwork panels, but is preferably designed as a separate joint tape holder, which is connected in any way with the formwork panels.

Die Verwendung eines begrenzt betondurchlässigen Materials für die Schaltafel hat mehrere Vorteile. Zum einen bietet dieses Material einen optimalen Untergrund für das Ankleben der Sperrmatte. Insbesondere bei Verwendung von Klebern, die in größerer Menge aufgebracht werden, wie dies bei Klebern auf Zementbasis der Fall ist, bieten die betondurchlässigen Öffnungen in der Schaltafel genügend Raum, dass der Kleber die Schaltafel umfließen kann und somit eine dauerhafte Befestigung der Sperrmatte möglich ist. Zum anderen wird durch das begrenzt betondurchlässige Material die Anbindung des verlorenen Abschalelements im Beton wesentlich verbessert.The use of a limited permeable material for the formwork panel has several advantages. On the one hand, this material provides an optimal base for sticking the barrier mat. In particular, when using adhesives that are applied in larger quantities, as is the case with cement-based adhesives, the concrete-impermeable openings in the formwork panel provide sufficient space for the adhesive to flow around the formwork panel, thus permitting permanent attachment of the blocking mat. On the other hand, the connection of the lost Abschalelements in concrete is significantly improved by the limited concrete permeable material.

Die Verbindung der Schaltafel mit der Aussteifung und dem Fugenbandhalter erfolgt bevorzugt durch Schweißen.The connection of the formwork panel with the stiffener and the joint tape holder is preferably carried out by welding.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnungen näher erläutert. Es zeigen:

An embodiment of the invention will be explained in more detail with reference to the drawings. Show it:

Fig. 2
a plan view of an inventive Abschalelement.

In den Fig. 1 und 2 ist ein erfindungsgemäßes Abschalelement 1 zum Abschalen von Dehnfugen in Wänden und Platten oder dgl. ersichtlich. Das Abschalelement enthält ein Schalungsmaterial 2 in Form zweier Schaltafeln 2a, 2b. Das Schalungsmaterial ist bevorzugt betondurchlässsig, was am einfachsten mit Hilfe eines Streckmetallbleches oder einer Gittermatte zu verwirklichen ist (in Fig.2 aus Gründen einer besseren Übersichtlichkeit nur bereichsweise angedeutet). Lochbleche oder andere perforierte Materialien können jedoch ebenfalls eingesetzt werden. Es ist weiterhin möglich, als Schalungsmaterial 2 auch irgendein anderes Material mit Vorsprüngen oder Oberflächenrauigkeiten einzusetzen, die eine verbesserte Anbindung an den Beton und/oder einen nachfolgend noch zu beschreibenden Kleber bieten. Die durch ein durchbrochenes Schalungsmaterial gebildeten Öffnungen können jedoch größer sein als dies bei den üblichen verlorenen Schalungselementen der Fall ist, da die Schaltafeln lediglich den Betonierdruck aufnehmen müssen und keine Anschlussfläche zum anderen Betonierabschnitt bilden.In the Fig. 1 and 2 is an inventive Abschalelement 1 for Abschalen of expansion joints in walls and plates or the like. Obvious. The formwork element contains a formwork material 2 in the form of two formwork panels 2a, 2b. The formwork material is preferably permeable to concrete, which is most easily achieved with the aid of an expanded metal sheet or a grid mat (in Fig.2 for reasons of clarity only partially indicated). However, perforated sheets or other perforated materials can also be used. It is also possible to use as shuttering material 2, any other material with protrusions or surface roughness, which provide an improved connection to the concrete and / or an adhesive to be described below. However, the openings formed by a perforated formwork material may be larger than is the case with the usual lost formwork elements, since the formwork panels only need to accommodate the concreting pressure and form no connection surface to the other concreting section.

Die Schaltafeln sind in einer Ebene fluchtend miteinander ausgerichtet und über Bügel 3 so miteinander verbunden, dass zwischen benachbarten Kanten der beiden Schaltafeln 2a, 2b ein Spalt 4 zur Aufnahme einer Fugendichtung, insbesondere eines Fugenbandes, verbleibt. Der Bügel 3 wölbt sich über dem Spalt 4, um einen ausreichenden Freiraum für die Fugendichtung zu schaffen und ist mit zwei geraden Schenkeln 3a, 3b an den Schaltafeln 2a, 2b befestigt. Der Bogen 3 und die Schenkel 3a, 3b sind bevorzugt so steif, dass sie als Aussteifung für die Schaltafeln 2a, 2b wirken können. Bevorzugt bestehen der Bügel 3 und die beiden Schenkel 3a, 3b aus einem einzigen, entsprechend geformten Bewehrungsstab.The formwork panels are aligned in a plane aligned with each other and connected by brackets 3 so that between adjacent edges of the two formwork panels 2a, 2b, a gap 4 for receiving a joint seal, in particular a joint tape remains. The bracket 3 bulges over the gap 4 to provide sufficient clearance for the joint seal and is secured to the formwork panels 2a, 2b by two straight legs 3a, 3b. The sheet 3 and the legs 3a, 3b are preferably so stiff that they can act as a stiffener for the formwork panels 2a, 2b. Preferably, the bracket 3 and the two legs 3a, 3b consist of a single, correspondingly shaped reinforcing bar.

Außer dem Bügel 3 mit seinen Schenkeln 3a, 3b sind noch weitere Aussteifungselemente vorgesehen, die insgesamt die Aussteifung 6 des Abschalelementes 1 bilden. Die Aussteifung 6 kann beispielsweise herkömmliche Gitterträger 7 und einzelne Bewehrungsstäbe 8 aufweisen. Im dargestellten Ausführungsbeispiel ist mit jeder Schaltafel 2a, 2b jeweils ein Gitterträger 7a, 7b verbunden, der auf den jeweiligen Schenkeln 3a, 3b sitzt und parallel zum Spalt 4 verläuft. Als Gitterträger kann jeder herkömmliche Gitterträger verwendet werden; dargestellt ist ein Gitterträger mit dreieckigem Querschnitt, dessen Ecken durch Stäbe und dessen zwei Seiten oberhalb der Basis jeweils durch eine wellenförmig gebogene Bewehrungsschlange gebildet werden.In addition to the bracket 3 with its legs 3a, 3b, further stiffening elements are provided, which together form the stiffener 6 of the Abschalelementes 1. The stiffener 6 may, for example, conventional lattice girders 7 and 8 have individual reinforcing bars. In the illustrated embodiment, with each panel 2a, 2b each one Lattice girders 7a, 7b connected, which sits on the respective legs 3a, 3b and runs parallel to the gap 4. As a truss, any conventional lattice girder can be used; shown is a lattice girder with triangular cross-section, the corners are formed by bars and its two sides above the base in each case by a wavy curved reinforcing coil.

Die Bewehrungsstäbe 8 verlaufen quer zu den Gitterträgern 7 und im Wesentlichen parallel zu den Schenkeln 3a, 3b, liegen jedoch auf der den Schenkeln 3a, 3b abgewandten Seite auf den Gitterträgern 7a, 7b, diese rechtwinklig kreuzend, auf. Anstelle der dargestellten geraden Bewehrungsstäbe 8 können jedoch auch Gitterträger ähnlich den Gitterträgern 7 bzw. Bewehrungsmatten oder dgl. verwendet werden. Die Anzahl, Art und Anordnung der Aussteifungselemente hängt von den aufzunehmenden Kräften beim Betonieren ab und kann nach Bedarf variiert werden.The reinforcing rods 8 extend transversely to the lattice girders 7 and substantially parallel to the legs 3a, 3b, but lie on the side facing away from the legs 3a, 3b on the lattice girders 7a, 7b, crossing them at right angles. However, instead of the illustrated straight reinforcing bars 8, lattice girders similar to the lattice girders 7 or reinforcing mats or the like may be used. The number, type and arrangement of the stiffening depends on the forces to be absorbed during concreting and can be varied as needed.

Zum Festlegen der Fugendichtung ist eine Fugendichtungshalterung 9 vorgesehen. Obwohl es theoretisch möglich ist, die Fugendichtung , insbesondere ein elastomeres Fugenband direkt im Spalt 4 durch die beiden Kanten der Schalungstafeln 2a, 2b, insbesondere aus Streckmetall oder einer Gittermatte, zu halten, ist bevorzugt ein gesondertes Bauteil in Form eines Fugendichtungshalters 10 vorgesehen.To set the joint seal a joint seal holder 9 is provided. Although it is theoretically possible to hold the joint seal, in particular an elastomeric joint tape directly in the gap 4 through the two edges of the formwork panels 2a, 2b, in particular of expanded metal or a grid mat, a separate component in the form of a joint sealant holder 10 is preferably provided.

Der Fugendichtungshalter 10 im dargestellten Ausführungsbeispiel gemäß Fig. 1 enthält zwei Formteile 10a, 10b, die an eine mittlere Verdickung , beispielsweise eines Dehnkörpers (Mittelschlauch) eines Fugenbandes so angepasst sind, dass sie einen Aufnahmehohlraum für diese Verdickung bilden, in der die Verdickung festgelegt werden kann. Die Formteile 10a, 10b erstrecken sich kontinuierlich über die gesamte Länge des Spaltes 4. Im dargestellten Ausführungsbeispiel weisen die Formteile 10a, 10b jeweils die gleiche halbkreis- bzw. teilkreisförmig gebogene Form auf, können jedoch auch trapezförmig oder rechtwinklig ausgebildet sein. Die Formteile 10a, 10b sind jeweils über einen Steg 11a, 11 b an der jeweils zugeordneten Schaltafel 2a, 2b oder an Teilen der Aussteifung 6, beispielsweise den Schenkeln 3a, 3b befestigt, bevorzugt angeschweißt.The joint sealant holder 10 in the illustrated embodiment according to Fig. 1 contains two mold parts 10a, 10b, which are adapted to an average thickening, such as an expansion body (middle tube) of a joint strip so that they form a receiving cavity for this thickening, in which the thickening can be determined. The mold parts 10a, 10b extend continuously over the entire length of the gap 4. In the illustrated embodiment, the mold parts 10a, 10b each have the same semicircular or partially circularly curved shape, but may also be formed trapezoidal or rectangular. The molded parts 10a, 10b are each preferably fixed via a web 11a, 11b to the respective associated formwork panel 2a, 2b or to parts of the stiffener 6, for example the legs 3a, 3b, preferably welded.

Die Schaltafeln 2a, 2b, die Aussteifung 6 mit den Schenkeln 3a, 3b, den Gitterträgern 7a, 7b und den Bewehrungsstäben 8 sowie den Stegen 11a, 11b bestehen aus einem schweißbaren Material, insbesondere einem Eisen- oder Stahlwerkstoff, und sind miteinander verschweißt.The formwork panels 2a, 2b, the stiffener 6 with the legs 3a, 3b, the lattice girders 7a, 7b and the reinforcing bars 8 and the webs 11a, 11b consist of a weldable Material, in particular an iron or steel material, and are welded together.

An der dem Bügel 3 abgewandten Seite der Schaltafeln 2a, 2b ist jeweils eine Sperrmatte 12 befestigt, die aus einem ersten Sperrmattenteil 12a, das mit der ersten Schaltafel 2a verbunden ist, und einem zweiten Sperrmattenteil 12b besteht, das mit der zweiten Schaltafel 2b verbunden ist. Als Sperrmatte kann jedes flächenförmige Element verwendet werden. Bevorzugt besteht die Sperrmatte beispielsweise aus Mineral- oder Steinwolle oder anderen mineralischen Dämmstoffen, extrudiertem Hartschaum, bituminierten Weichfaserplatten oder anderen geeigneten Werkstoffen. Die beiden Sperrmattenteile 12a, 12b sind bevorzugt so groß wie die zugeordneten Schaltafeln 2a, 2b, so dass sie diese, insbesondere über den mit den Öffnungen versehenen Bereich, im wesentlichen vollflächig, aber ebenfalls unter Freilassung des Spaltes 4 überdecken.On the side facing away from the bracket 3 of the formwork panels 2a, 2b, a respective blocking mat 12 is fixed, which consists of a first locking mat part 12a, which is connected to the first switching board 2a, and a second blocking mat part 12b, which is connected to the second switching board 2b , As a barrier mat, each sheet-like element can be used. Preferably, the barrier mat, for example, mineral or rock wool or other mineral insulation, extruded hard foam, bituminized softboard or other suitable materials. The two barrier mat parts 12a, 12b are preferably as large as the associated formwork panels 2a, 2b, so that they cover them, in particular over the area provided with the openings, substantially over the entire area, but also leaving the gap 4 free.

Die Sperrmattenteile 12a, 12b sind an den Schaltafeln 12a, 12b angeklebt, und zwar bevorzugt direkt, wenn die Schaltafeln 2a, 2b die der Sperrplatte 12a, 12b zugewandte Oberfläche bilden. Der Kleber 13 kann vollflächig aufgetragen sein, kann jedoch auch bereichsweise in Form von Punkten oder Linien aufgetragen werden. Als Kleber 13 kann ein doppelseitig klebendes Klebeband oder jeder geeignete Klebstoff verwendet werden, bevorzugt ist jedoch ein Klebstoff auf Zementbasis. Ein geeigneter Kleber ist unter dem Markennamen "RACOFIX" auf dem Markt. Dieser Kleber kann auch dann eingesetzt werden, wenn die Dehnfuge brandgeschützt ausgebildet werden muss. Der Kleber erfüllt die Baustoffklasse A1 nach DIN 4102 (nicht brennbar, ohne organische Bestandteile) und ist in der Lage, Sperrmatten aus Materialien, die ebenfalls diese Baustoffklasse A1 erfüllen mit Metall zu verbinden.The barrier mat parts 12a, 12b are glued to the formwork panels 12a, 12b, preferably directly when the formwork panels 2a, 2b form the surface facing the blocking panel 12a, 12b. The adhesive 13 may be applied over the entire surface, but may also be applied in regions in the form of dots or lines. As the adhesive 13, a double-sided adhesive tape or any suitable adhesive may be used, but a cement-based adhesive is preferred. A suitable adhesive is marketed under the brand name "RACOFIX". This adhesive can also be used when the expansion joint must be designed fire-proof. The adhesive fulfills the building material class A1 according to DIN 4102 (non-combustible, without organic constituents) and is able to connect barrier mats made of materials that also meet this building material class A1 with metal.

Durch die Verklebung ist keinerlei Durchdringung der Sperrmatte notwendig, so dass das erfindungsgemäße Abschalelement 1 alle Anforderungen, insbesondere auch im Hinblick auf den Brandschutz, erfüllt.The bond does not require any penetration of the barrier mat, so that the shuttering element 1 according to the invention fulfills all requirements, in particular with regard to fire protection.

Das erfindungsgemäße Abschalelement wird als einbaufertige Einheit ausgebildet, d.h. es enthält neben den mit dem Bügel 3 verbundenen Schaltafeln 2a, 2b und den daran angeklebten Sperrmatten 12a, 12b auch die notwendige Aussteifung 6 und den Fugenbandhalter 10, so dass das Abschalelement 1 im Anlieferungszustand verbaut werden kann. Gegebenenfalls ist es jedoch auch möglich, die notwendigen Aussteifungen und/oder einen bevorzugten Fugenbandhalter erst auf der Baustelle mit dem Abschalelement zu verbinden.The formwork element according to the invention is designed as a ready-to-install unit, ie it contains, in addition to the connected to the bracket 3 formwork panels 2a, 2b and the adhered thereto blocking mats 12a, 12b and the necessary stiffener 6 and the joint tape holder 10, so that the Abschalelement 1 can be installed in the delivery state. Optionally, however, it is also possible to connect the necessary stiffeners and / or a preferred joint strip holder only on the construction site with the Abschalelement.

In Abwandlung der beschriebenen und gezeichneten Ausführungsbeispiele können auch andere Arten von Fugenbandhaltern, beispielsweise die in der DE 201 18 098 U beschriebenen Fugenbandhalter, und eine andere Konstruktion der Aussteifung eingesetzt werden. So muss z. B. die Aussteifung nicht symmetrisch an den Schaltafeln angeordnet sein. Es ist weiterhin möglich, beim Abschalelement Materialien zu verwenden, die nicht unbedingt schweißbar sind. Die Befestigung kann in diesem Falle auch durch Rödeln, Schrauben oder dgl. erfolgen, solange die Sperrmatte nicht durchdrungen wird.In a modification of the described and illustrated embodiments, other types of joint tape holders, for example, in the DE 201 18 098 U described joint tape holder, and another construction of the stiffener can be used. So z. B. the stiffener can not be arranged symmetrically on the formwork panels. It is also possible to use the Abschalelement materials that are not necessarily weldable. The attachment can be done in this case by dozing, screws or the like., As long as the barrier mat is not penetrated.
