Abstract

Resiliently deformable safety covering tiles have a base 2 made of rigid material such as concrete, and a cover body 3 provided on the top side of the base made of resiliently deformable material such as rubber. These safety covering tiles should be easy to lay while exhibiting no corrugation or bulging on their top side 5 during changes in temperature. To achieve this, on a continuous edge portion 10 of a covering tile portion 4 of the cover 3, at the height of a ledge 15 of the base 2, one or more lateral projections 18 are distributed over the periphery of the cover. The continuous edge portion 10 has a gap-forming reduced portion 19 at the height of spacers 7 and of the covering tile 4 and has at the height of the spacers 7 a reduced cross-section 22 which permits lateral movements.

Description

Die Erfindung bezieht sich auf eine elastisch nachgiebige Sicherheitsbelagsplatte, insbesondere für Böden, aus einem starren Trägerkörper und einem auf dessen Oberseite vorgesehenen Belagskörper aus elastisch nachgiebigem Material, der eine im Abstand von dem Trägerkörper gehaltene Deckplatte aufweist, die auf ihrer Unterseite lediglich eine Vielzahl von noppenartigen Abstandshaltern besitzt, die im wesentlichen gleichmäßig verteilt auf der Oberfläche des Trägerkörpers lose aufsitzen, wobei die Deckplatte einen umlaufenden Rand mit einer nach innen gerichteten Umbiegung aufweist, mit der sie am Trägerkörper verankert ist, wobei der Trägerkörper eine umlaufende, gestufte Kante mit einer auf der der Deckplatte abgekehrten Seite angeordneten umlaufenden Ausnehmung aufweist, der umlaufende, außerhalb des Umrisses des Trägerkörpers angeordnete Rand der Deckplatte mit seiner Umbiegung in die Aussparung des Trägerkörpers eingreift und unter der Umbiegung des umlaufenden Randes der Deckplatte ein Freiraum vorgesehen ist. Solche Sicherheitsbelagsplatten werden als Fertigbodenteile bevorzugt für Kleinspielfelder, als Fallschutzböden auf Kinderspielplätzen und unter Spiel- und Sportgeräten, aber auch bei sonstigen Freizeitanlagen verwendet. Sie können auf beliebigem Untergrund aufgelegt werden, beispielsweise in ein Sandbett, aber auch auf eine Rohbetondecke o. dgl. unter Zwischenschaltung von Dämmaterial.The invention relates to an elastically resilient safety covering sheet, especially for floors, made of a rigid support body and provided on its upper side B elagskörper of elastically resilient material having a held at a distance from the carrier body cover plate on its underside only a plurality of has knob-like spacers, which sit loosely on the surface of the carrier body, substantially uniformly distributed, the cover plate having a circumferential edge with an inward bend with which it is anchored to the carrier body, the carrier body having a circumferential, stepped edge with a has the circumferential recess arranged on the side facing away from the cover plate, the circumferential edge of the cover plate arranged outside the outline of the support body engages with its bend in the recess of the support body and under the bend of the circumferential edge of the cover plate a free space is provided.

Die Erfindung geht von einer Sicherheitsbelagsplatte mit den genannten Merkmalen aus, wie sie aus einer nicht vorveröffentlichten älteren Anmeldung (P 31 06 784.0-25) der Anmelderin beschrieben ist. Damit wird eine Sicherheitsbelagsplatte geschaffen, bei der ein gleichmäßiger Kraftabbau über die gesamte Platte und über deren Grenzen im Verbund hinweg erreicht wird. Die Sicherheitsbelagsplatte weist in allen ihren Bereichen gleiche oder zumindest etwa gleiche Nachgiebigkeit auf. Es ist keinerlei Verankerung zwischen der Innenseite der Deckplatte bzw. den Abstandshaltern und der Oberfläche des Trägerkörpers vorgesehen. Die Verankerung wird einerseits mit Hilfe des umlaufenden Randes und der nach innen gerichteten Umbiegung an der gestuften Kante gehalten und die noppenartigen Abstandshalter werden klar funktionell getrennt. Damit behindert die Verankerung die federnde Nachgiebigkeit der Deckplatte nicht mehr. Der umlaufende Rand des Belagskörpers besitzt der jeweils benachbarten Platte zugekehrt, eine senkrechte Begrenzungsfläche, die vom Bereich der Abstandshalter bis über einen Großteil der Höhe des Trägerkörpers reicht, so daß bei der Verlegung dieser Sicherheitsbelagsplatten im Verbund die einzelnen Platten mit diesen vertikalen Flächen aneinanderstoßend zu liegen kommen. Durch die Beweglichkeit der Belagskörper relativ zu den Trägerkörpern tritt bei Temperaturänderungen infolge unterschiedlicher Ausdehnungskoeffizienten des Belagskörpers einerseits und des Trägerkörpers andererseits eine unschöne Wellenbildung der Oberflächen der Deckplatten auf. Insbesondere bei starker Sonneneinstrahlung auf im Verbund eng aneinanderstoßend verlegte Sicherheitsbelagsplatten beobachtet man eine beulenartige Aufwölbung der einzelnen Belagskörper, so daß die Oberfläche insgesamt uneben wird.The invention is based on a safety covering plate with the features mentioned, as described by the applicant in an older application (P 31 06 784.0-25) which has not been published beforehand. This creates a safety covering plate in which an even reduction in force is achieved across the entire plate and across its boundaries in the composite. The safety covering plate points in all of its areas chen the same or at least about the same compliance. There is no anchoring between the inside of the cover plate or the spacers and the surface of the carrier body. The anchoring is held on the one hand with the help of the peripheral edge and the inward bend at the stepped edge and the knob-like spacers are clearly separated functionally. The anchoring no longer impedes the resilient flexibility of the cover plate. The circumferential edge of the covering body faces the adjacent plate, a vertical boundary surface which extends from the area of the spacers to a large part of the height of the support body, so that when these safety covering plates are laid together, the individual plates with these vertical surfaces lie abutting come. Due to the mobility of the covering bodies relative to the carrier bodies, unsightly undulation of the surfaces of the cover plates occurs when the temperature changes due to different expansion coefficients of the covering body on the one hand and of the carrier body on the other. In particular in the case of strong solar radiation on security covering plates laid close to one another in a bond, a bulge-like bulging of the individual covering bodies is observed, so that the surface as a whole becomes uneven.

Sicherheitsbelagsplatten mit einem Teil der im Oberbegriff des Anspruches 1 angegebenen Merkmale sind auch aus der GB-PS 1 229 516 oder auch aus der DE-PS 23 29 542 bekannt. Dort wird die vorhandene Deckplatte des Belagskörpers über Ankerkörper mit der Oberfläche des Trägerkörpers verbunden, wobei die Ankerkörper in Abständen zwischen den Abstandshaltern angeordnet sind und in dem ausgehärteten Material des Trägerkörpers verankert sind. Außerdem besitzen diese bekannten Sicherheitsbelagsplatten einen umlaufenden Rand, der sich auf die Oberseite der Trägerkörper aufsetzt und damit eine Randabstützung bildet. Bei diesen bekannten Sicherheitsbelagsplatten ist die vertikale Seitenfläche jeder Platte an dem Belagskörper und dem Trägerkörper durchgehend vorgesehen. Werden diese Platten, wie üblich, ohne Spiel im Verband verlegt, dann führt eine Temperaturänderung zu einer vergleichsweise verstärkten Wellen- und Beulenbildung, weil zusätzlich noch das zwischen Belagskörper und Trägerkörper eingespannte Luftpolster durch den auf dem Trägerkörper aufliegenden Rand etwa abgedichtet gehalten wird.Security covering plates with part of the features specified in the preamble of claim 1 are also known from GB-PS 1 229 516 or also from DE-PS 23 29 542. There, the existing cover plate of the covering body is connected to the surface of the carrier body via anchor bodies, the anchor bodies being arranged at intervals between the spacers and anchored in the hardened material of the carrier body. In addition, these known safety covering plates have a peripheral edge, which sits on the top of the carrier body and thus forms an edge support. In these known safety covering plates, the vertical side surface of each plate is provided continuously on the covering body and the carrier body. If, as usual, these panels are laid in the dressing without play, a change in temperature leads to a comparatively increased formation of waves and dents, because in addition the air cushion clamped between the covering body and carrier body is kept approximately sealed by the edge resting on the carrier body.

Das DB-GM 70 13 835-zeigt eine Belagsplatte, bei der der Belagskörper über Hinterschneidungen mit dem Trägerkörper verbunden ist. Dabei ist ein Luftpolster zwischen Belagskörper und Trägerkö-rper nicht vorgesehen, sondern es sind die Verankerungsstellen und der mit einer Umbiegung versehene umlaufende Rand in der ausgehärteten Masse des Trägerkörpers verankert. Auch hierbei sind die Platten an den vier Seiten durch vertikal durchgehende Flächen begrenzt. Das DB-GM 76 09 345 zeigt eine ähnlich ausgebildete Bodenplatte, bei der jedoch die Deckplatte umlaufend seitlich mit angeformten Randstreifen verbreitert ist, die dem Zweck dienen, den Belagskörper nach seiner Herstellung maßhaltig zu stanzen bzw. die Randstreifen entsprechend der geforderten Maßhaltigkeit zu beschneiden. Auch hier erfolgt die Einformung der Verankerungsglieder und des umlaufenden Randes in das Material des Trägerkörpers bei dessen Aushärtung. Das DB-GM 77 24 504 zeigt insofern eine Weiterbildung, als hier auf der Unterseite der Deckplatte Abstandshalter vorgesehen sind, zwischen denen sich ein Luftpolster ausbilden kann. Der mit der Umbiegung versehene umlaufende Rand ist auch hier formschlüssig im Material des Trägerkörpers verankert. Der Belagskörper weist in Höhe der Deckplatte eine umlaufende Randverb-reiterung auf, die gegenüber der ansonsten senkrechten Begrenzungsfläche übersteht. Eine solche Ausbildung ist für die Verlegung der Platten im Verbund insofern hinderlich, als die Platten mit diesen Randverbreiterungen aneinanderstossend so verlegt werden müssen., daß die Platten wenigstens bei der Verlegungstemperatur eine ebene Oberfläche aufweisen. Auch hier besteht jedoch die Gefahr, daß die Belagskörper insbesondere bei starker Sonneneinstrahlung die schon beschriebene Wellen- und Beulenbildung zeigen, weil sie sich im Bereich der Deckplatte aneinander abstützen und durch die Einformung der Umbiegung des Randes zusätzlich noch das Luftpolster abgedichtet eingeschlossen ist, welches sich bei Wärmeeinwirkung entsprechend ausdehnt.The DB-GM 70 13 835 shows a covering plate in which the covering body is connected to the carrier body via undercuts. An air cushion between the covering body and carrier body is not provided, but the anchoring points and the circumferential edge provided with a bend are anchored in the hardened mass of the carrier body. Here, too, the panels are delimited on the four sides by vertically continuous surfaces. The DB-GM 76 09 345 shows a similarly designed base plate, in which, however, the cover plate is widened laterally with molded edge strips that serve the purpose of punching the covering body to size after its manufacture or trimming the edge strips according to the required dimensional accuracy. Again, the indentation is carried out of the V erankerungsglieder and the circumferential edge in the material of the carrier body as it hardens. DB-GM 77 24 504 shows a further development in that spacers are provided on the underside of the cover plate, between which an air cushion can form. The circumferential edge provided with the bend is also positively anchored in the material of the carrier body. The covering body has a circumferential widening at the level of the cover plate, which protrudes from the otherwise vertical boundary surface. Such training is This is a hindrance to the laying of the panels in the composite, in that the panels with these edge widenings have to be laid so that they abut one another in such a way that the panels have a flat surface, at least at the laying temperature. However, here too there is a risk that the covering bodies show the wave and bump formation already described, especially in strong sunlight, because they are supported against each other in the area of the cover plate and the air cushion is additionally sealed in by the shaping of the bending of the edge, which is sealed expands accordingly when exposed to heat.

Man kann der beschriebenen Wellen- und Beulenbildung, jedenfalls bei der Belagsplatte der eingangs beschriebenen Art dadurch entgegenwirken, daß die einzelnen Platten mit gegenseitigem Abstand verlegt werden, also unter Einhaltung einer durchgehenden Fu-ge. Um diese Fugen gleichmäßig zu gestalten, muß erhebliche Sorgfalt angewandt werden. Auch einzusetzende Hilfsvorrichtungen, wie Fugenabstandshalter, können hier notwendig werden. Trotz dieser, die Verlegearbeit erschwerenden Maßnahmen kann es beim Gebrauch des Bodenbelages dazu kommen, daß einzelne Platten ihre relative Lage zu den Nachbarplatten verändern und dabei im Bereich der Fuge aneinander stoßen, so daß auch hier - wenn auch in geringerem Maße - die Wellen- und Beulenbildung auftreten kann. M an can counteract the wave and bump formation described, at least in the case of the covering plate of the type described at the outset, in that the individual plates are laid with a mutual spacing, that is to say while maintaining a continuous foot. Considerable care must be taken to make these joints even. Auxiliary devices to be used, such as joint spacers, may also be necessary here. Despite these measures, which complicate the laying work, it can happen when using the floor covering that individual panels change their relative position to the neighboring panels and thereby abut each other in the area of the joint, so that here too - if to a lesser extent - the undulations and Bump formation can occur.

Der Erfindung liegt die Aufgabe zugrunde, eine Sicherheitsbelagsplatte der eingangs beschriebenen Art zu schaffen, die sich einerseits leicht und ohne zusätzliche Hilfsmittel verlegen läßt und bei der andererseits die Wellen- und Beulenbildung beseitigt ist, so daß Temperatureinwirkungen nicht zu einer Deformation der freien Oberfläche der Belagskörper führen können.The invention has for its object to provide a safety covering plate of the type described above, which can be easily installed on the one hand and without additional aids and on the other hand the wave and bump formation is eliminated so that temperature effects do not lead to a deformation of the free surface of the covering body being able to lead.

Erfindungsgemäß wird dies dadurch erreicht, daß an dem umlaufenden Rand der Deckplatte in Höhe der Stufe des Trägerkörpers ein oder mehrere Vorsprünge über den Umfang des Belagskörpers verteilt vorgesehen sind, daß der umlaufende Rand in Höhe der Abstandshalter und der Deckplatte eine fugenbildende Ausspa- rung aufweist, und daß der umlaufende Rand in Höhe der Abstandshalter einen seitliche Bewegungen gestattenden verminderten Querschnitt aufweist. Mit dieser Ausbildung wird eine Doppelfunktion erreicht. Die Sicherheitsbelagsplatten stützen sich direkt aneinander ab, so daß ihre Verlegung vergleichsweise einfach ist. Die Platten können direkt aneinanderstoßend verlegt werden. Abstandshalter o. dgl. Hilfsmittel entfallen bei der Verlegung. Trotzdem behindert diese Abstützung nicht die Ausdehnung der Deckplatte bei Temperaturänderungen. Die gegenseitige Abstützung der Platten aneinander ist nämlich in einen Bereich verlegt, der einen beträchtlichen Abstand von der Oberfläche der Deckplatte aufweist. In Verbindung damit ist der Querschnitt des Randes in Höhe der Übergangsstelle zwischen dem Trägerkörper und den Abstandshaltern des Belagskörpers gleichsam mit einer Schwachstelle versehen, die das seitliche Wegbiegen bzw. Auffedern oder Zusammenfedern des Belagskörpers in der Ebene der Deckplatte gestattet, und zwar ohne, daß die frei sichtbare Oberfläche der Deckplatte dabei aus ihrer Ebene heraus Beulen- oder wellenartig deformiert würde. Zwischen den einzelnen Belagskörpern in Höhe der Deckplatte und zumindest im wesentlichen über die Höhe der Abstandshalter bildet sich somit eine Fuge, die nicht nur ein dekoratives Aussehen hat, sondern auch die beschriebene technische Wirkung der Ausdehnung des Belagskörpers in diesem Bereich bei Temperaturerhöhung zuläßt. Ein weiterer Vorteil dieser erfindungsgemäßen Ausbildung ist darin zu sehen, daß die Schwachstelle im Bereich des umlaufenden Randes auch das Aufknöpfen des Belagskörpers auf den Trägerkörper nach dessen Aushärtung und ggf. unmittelbar vor der Verlegung auf der Baustelle erleichtert und vereinfacht.This is achieved in that the support body one or more projections are provided distributed over the periphery of the covering body on the peripheral edge of the cover plate in height of the step, that the peripheral edge in height of the spacers and the top plate has a gap-forming A usspa- tion according to the invention , and that the peripheral edge at the level of the spacers has a reduced cross-section allowing lateral movements. With this training, a dual function is achieved. The safety covering panels are supported directly against one another, so that their laying is comparatively simple. The panels can be laid directly next to each other. Spacers or the like. Aids are not required when laying. Nevertheless, this support does not hinder the expansion of the cover plate when the temperature changes. The mutual support of the plates to one another is in fact moved to an area which is at a considerable distance from the surface of the cover plate. In connection with this, the cross-section of the edge at the level of the transition point between the carrier body and the spacers of the covering body is provided with a weak point, as it were, which allows the lateral bending or springing back or springing together of the covering body in the plane of the cover plate, without the freely visible surface of the cover plate would be deformed out of its level in a bulge or wave-like manner. A joint is thus formed between the individual covering bodies at the height of the cover plate and at least essentially above the height of the spacers, which not only has a decorative appearance, but also permits the described technical effect of the expansion of the covering body in this area when the temperature rises. Another advantage of this design according to the invention can be seen in the fact that the weak point in the area of the circumferential edge also the buttoning of the covering body onto the carrier body after it has hardened and, if necessary, simplified and simplified immediately before laying on the construction site.

Der Vorsprung kann mit halber Fugenbreite umlaufend um den umlaufenden Rand vorgesehen sein, so daß der Vorsprung an allen vier seitlichen Begrenzungsflächen gleiches Aussehen aufweist. Die beiden Vorsprünge je zweier benachbarter Sicherheitsbelagsplatten bilden damit die Fuge aus. Diese Ausbildung hat den Vorteil, daß die einzelnen Platten in beliebiger Relativlage, also bei insgesamt vier Möglichkeiten bei quadratischer Ausbildung aneinander angelegt werden können. Es ist aber auch möglich, daß mehrere Vorsprünge mit ganzer Fugenbreite über den Umfang verteilt und einander ergänzend angeordnet sind. Dies bringt vorteilhaft eine gewisse gegenseitige Verzahnung im Bereich der Vorsprünge. Allerdings ist es hierbei erforderlich, jede Platte ausgerichtet zur anderen an diese anzulegen, wobei es nur eine einzige Anschlußmöglichkeit gibt.The projection can be provided around the circumferential edge with half the joint width, so that the projection has the same appearance on all four lateral boundary surfaces. The two protrusions each of two adjacent safety covering panels form the joint. This training has the advantage that the individual plates can be placed against each other in any relative position, that is, with a total of four possibilities with a square training. However, it is also possible for a plurality of projections with the entire joint width to be distributed over the circumference and to be arranged to complement one another. This advantageously brings about a certain mutual interlocking in the area of the projections. However, it is necessary to place each plate aligned to the other, with only one connection option.

In allen Fällen ist es nicht erforderlich, daß der oder die Vorsprünge lückenlos über den Umfang durchgehen. Es ist vielmehr möglich, daß die Vorsprünge an den Freiraum anschliessende Durchbrechungen aufweisen, durch die hindurch eine beschleunigte Wasserabfuhr erfolgt und über die auch das Luftpolster unter den Abstandshaltern an die Atmosphäre angeschlossen ist.In all cases, it is not necessary for the protrusion (s) to go over the entire circumference. Rather, it is possible for the projections to have openings which adjoin the free space, through which accelerated water drainage takes place and via which the air cushion under the spacers is also connected to the atmosphere.

Wesentlich ist, daß die Vorsprünge jedenfalls in Höhe der Stufe des Trägerkörpers vorgesehen sind. Wenn der oder die Vorsprünge bis in den Bereich der Umbiegung reichend vorgesehen sind, so stört dies nicht, bringt im Gegenteil eine Entformungshilfe für die Belagskörper, weil sich diese leichter entformen lassen.It is essential that the projections are in any case provided at the level of the step of the carrier body. If the protrusion or protrusions are provided extending into the area of the bend, this does not interfere. On the contrary, a mold removal aid for the covering bodies is provided, because these can be removed from the mold more easily.

Zwischen der umlaufenden Stufe des Trägerkörpers und dem die Vorsprünge tragenden Teil des Randes des Belagskörpers kann ein Spalt vorgesehen sein. Es handelt sich hierbei um einen eng begrenzten Spalt, also um Spiel, welches bei der Herstellung eingehalten wird. Dieses Spiel dient dem erleichterten Aufknüpfen der Belagskörper auf die Trägerkörper einerseits und dem Anschluß des Luftpolsters unter der Deckplatte an die Atmosphäre, und zwar über den Freiraum und ggf. die Durchbrechungen im Bereich der Vorsprünge.A gap can be provided between the circumferential step of the carrier body and the part of the edge of the covering body that carries the projections. This is a narrowly defined gap, i.e. a game that is observed during production. This match is used to facilitate A ufknüpfen the lining body to the support body on the one hand and the connection of the air cushion under the cover plate to the atmosphere, through the space and possibly the openings in the region of the projections.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im Folgenden näher beschrieben. Es zeigen:

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below. Show it:
  • F ig. 1- a vertical section through parts of two adjacent safety covering panels laid in a bond,
  • Fig. 2 is a plan view of the covering body in a reduced view with a second embodiment of the projections and
  • F ig. 3 shows a representation similar to FIG. 2 with a further embodiment of the projections.

Jede Sicherheitsbelagsplatte 1 besteht im wesentlichen aus zwei Teilen, nämlich einem Trägerkörper 2 und je einem Belagskörper 3. Die Trägerkörper 2 können aus Beton, Holz, Kunststoff o. dgl. bestehen, während die Belagskörper 3 in der Regel aus Gummi hergestellt sind. Jeder Belagskörper 3 weist eine Deckplatte 4 auf, die auf ihrer Oberseite 5 die nutzbare Oberfläche abgibt, während auf ihrer Unterseite 6 noppenförmige Abstandshalter 7 in großer Vielzahl und regelmäßiger Anordnung vorgesehen sind, die zweckmäßig aus Entformungsgründen konisch zulaufen und auf der Oberfläche 8 des Trägerkörpers 2 lose aufliegen. Auf diese Art und Weise wird die Deckplatte 4 im Abstand von der Oberfläche 8 des Trägerkörpers 2 gehalten, wobei zwischen den Abstandshaltern 7 ein Luftpolster 9 gebildet ist, welches, wie noch später ausgeführt wird, mit der Atmosphäre in Verbindung steht. Die Abstandshalter 7 sind in ihrer Höhe, Ausbildung und Anordnung auf die gewünschten Federungseigenschaften und den Kraftabbau der Sicherheitsbelagsplatte 1 abgestimmt bzw. abgestellt. Die Abstandshalter 7 erstrecken sich dabei in regelmäßiger Anordnung über die gesamte Unterseite der Deckplatte 4.Each safety covering plate 1 consists essentially of two parts, namely a support body 2 and one covering body 3 each. The support bodies 2 can be made of concrete, wood, plastic or the like, while the covering bodies 3 are generally made of rubber. Each covering body 3 has a cover plate 4, which gives off the usable surface on its upper side 5, while on its underside 6 knob-shaped spacers 7 are provided in a large number and in a regular arrangement, which taper expediently for reasons of demolding and on the surface 8 of the carrier body 2 lie loose. In this way, the cover plate 4 is held at a distance from the surface 8 of the carrier body 2, an air cushion 9 being formed between the spacers 7, which, as will be explained later, is connected to the atmosphere. The spacers 7 are matched in their height, design and arrangement to the desired suspension properties and the reduction in force of the safety covering plate 1. The spacers 7 extend in a regular arrangement over the entire underside of the cover plate 4.

An die Deckplatte 4, also mit Abstand zum Trägerkörper 2, schließt sich ein umlaufender, im wesentlichen vertikal sich erstreckender Rand 10 an, der außerhalb der Umrißlinie des Trägerkörpers 2 vorgesehen ist. Dieser Rand 10 reicht nicht nur bis zur Oberfläche 8 des Trägerkörpers 2, die er selbst vermeidet, sondern noch weiter nach unten bis zu einem Teil der Höhe des Belagskörpers 3. Dabei ist an seinem unteren Ende eine Umbiegung 11 vorgesehen, die auf den Trägerkörper 2 zu gerichtet ist. Unterhalb der Umbiegung 11 bzw. im Bereich einer gestuften Kante des Trägerkörpers 2 ist ein Freiraum 12 gebildet bzw. angeordnet. Der Trägerkörper 2 besitzt in diesem Bereich eine gestufte Kante 13, die sich von der Oberfläche 8 bis auf eine Unterlage, eine Rohbetondecke o. dgl. 14 erstreckt. Die gestufte Kante 13 besitzt im Anschluß an die Oberfläche 8 zunächst eine Stufe 15 und verläuft dann schräg etwa in 45° zurückspringend, so daß der Trägerkörper hier eine Ausnehmung 16 aufweist. Diese Ausnehmung 16 geht in den Freiraum 12 über. Der schräge Verlauf in 45° der gestuften Kante 13 dient zum erleichterten Entformen des in der Regel aus Beton bestehenden Trägerkörpers 2 aus einer Form. Zwischen der Stufe 15 und der Innenseite des Randes 10 kann ein Spalt 17 vorgesehen sein, der eng begrenzt ist und nur ein positives Spiel aus herstellungstechnischen Gründen darstellt. Der umlaufende Rand 10 weist zumindest im Bereich bzw. in Höhe der Stufe 15 der gestuften Kante 13 des Trägerkörpers 2 nach außen vorspringend einen Vorsprung 18 auf. Dieser Vorsprung 18 reicht bis in den Bereich der Umbiegung 11 hinab und ist umlaufend auf allen vier Seiten einer Sicherheitsbelagsplatte 1 mit beispielsweise quadratischem Umriß vorgesehen. Oberhalb des Vorsprungs 18 weist der Rand 10 eine umlaufende Aussparung 19 auf. Die beiden Aussparungen zweier benachbarter Sicherheitsbelagsplatten 1 bilden zusammen und entsprechend den Vorsprüngen 18 eine Fuge 20, die im wesentlichen die Höhe der Deckplatte 4 und der Abstandshalter- 7 abdeckt. Durch diese besondere Querschnittsgestaltung des Randes 10 besitzt dieser eine Schwachstelle 21 mit vermindertem Querschnitt 22, so daß bei Temperaturänderungen sich die Deckplatte 4 zwar ausdehnen oder zusammenziehen kann, dabei aber eine Bewegung um die Schwachstelle 21 herum zugelassen wird, so daß jedenfalls die Oberseite 5 der Deckplatte 4 immer waagerecht verbleibt und eine Wellen- bzw. Beulenbildung vermieden wird.The cover plate 4, that is to say at a distance from the carrier body 2, is adjoined by a circumferential, essentially vertically extending edge 10 which is provided outside the outline of the carrier body 2. This edge 10 not only extends to the surface 8 of the carrier body 2, which it avoids itself, but further down to a part of the height of the covering body 3. A bend 11 is provided at its lower end, which on the carrier body 2 is too directed. A free space 12 is formed or arranged below the bend 11 or in the region of a stepped edge of the carrier body 2. In this area, the carrier body 2 has a stepped edge 13, which extends from the surface 8 to a base, a raw concrete ceiling or the like 14. The stepped edge 13 initially has a step 15 following the surface 8 and then runs back obliquely at approximately 45 °, so that the carrier body has a recess 16 here. This recess 16 merges into the free space 12. The oblique course at 45 ° of the stepped edge 13 serves to facilitate removal from the mold of the support body 2, which is generally made of concrete, from a mold. Between the step 15 and the inside of the edge 10, a gap 17 can be provided, which is narrowly limited and only one represents positive game for manufacturing reasons. The peripheral edge 10 has, at least in the region or at the level of the step 15 of the stepped edge 13 of the carrier body 2, a projection 18 projecting outwards. This projection 18 extends down into the region of the bend 11 and is provided all around on all four sides of a safety covering plate 1 with, for example, a square outline. The edge 10 has a circumferential recess 19 above the projection 18. The two recesses of two adjacent safety covering plates 1 together and corresponding to the projections 18 form a joint 20 which essentially covers the height of the cover plate 4 and the spacer 7. Due to this special cross-sectional design of the edge 10, this has a weak point 21 with a reduced cross-section 22, so that the cover plate 4 can expand or contract in the event of temperature changes, but movement is permitted around the weak point 21, so that in any case the top side 5 of the Cover plate 4 always remains horizontal and a wave or bulge is avoided.

Fig. 2 zeigt eine Abwandlung des Belagskörpers 3 insofern, als hier mehrere Vorsprünge 23 anstelle eines einzigen umlaufenden Vorsprunges 18 verteilt über den Umfang der Sicherheitsbelagsplatte 1 vorgesehen sind. Die Vorsprünge 23 ergänzen einander, wenn die Sicherheitsbelagsplatten 1 im Verband verlegt sind. Die Vorsprünge 23 bestimmen hier die gesamte Breite der Fuge 20. Die Sicherheitsbelagsplatten 1 müssen hier richtungsorientiert aneinander angelegt werden, wobei jedoch durch die schrägenden Vorsprünge 23 eine gewisse Selbstzentrierwirkung während des Verlegens eintritt. Hierdurch wird nicht nur der Verlegevorgang selbst vereinfacht und begünstigt, sondern auch ein seitliches Auswandern der Belagskörper 3 verhindert. Die Ausbildung des Vorsprunges 18 nach Fig. 1 bzw. der Vorsprünge 23 nach Fig. 2 kann umlaufend vorgesehen sein. Es ist jedoch auch möglich, Durchbrechungen anzuordnen, um auf diese Weise einerseits einen Wasserabfluß von oben und andererseits einen unmittelbaren Anschluß des Luftpolsters 9 an die Atmosphäre zu erzielen. F ig. 2 shows a modification of the covering body 3 in that a plurality of projections 23 are provided here instead of a single circumferential projection 18 distributed over the circumference of the safety covering plate 1. The projections 23 complement each other when the safety covering plates 1 are laid in the association. The projections 23 determine the entire width of the joint 20 here. The safety covering plates 1 have to be placed against one another in a direction-oriented manner, although the inclined projections 23 have a certain self-centering effect during the laying. This not only simplifies and favors the laying process itself, but also prevents the covering body 3 from migrating sideways. The design of the projection 18 according to FIG. 1 or of the projections 23 according to FIG. 2 can be provided all around. It However, it is also possible to arrange openings in order to achieve water drainage from above on the one hand and a direct connection of the air cushion 9 to the atmosphere on the other hand.

Bei der Ausführungsform nach Fig. 3 ist dies verwirklicht. Dort sind Vorsprünge 24 und 25 mit Abstand zueinander und relativ zueinander positioniert vorgesehen, wobei im Verband immer ein Vorsprung 24 zwischen zwei Vorsprüngen 25 eingreift. Zwischen den Vorsprüngen 24 bzw. 25 bleiben damit Durchbrechungen 26 frei.This is realized in the embodiment according to FIG. 3. There projections 24 and 25 are provided at a distance from one another and positioned relative to one another, a projection 24 always engaging between two projections 25 in the assembly. Openings 26 thus remain free between the projections 24 and 25.

Bei allen Ausführungsformen sind der Vorsprung 18 bzw. die Vorsprünge 23 bzw. 24 und 25 jedenfalls so angeordnet, daß sie sich in Höhe der Stufe 15 befinden, dagegen der Raum darüber durch eine Aussparung 19 freigehalten ist und sich somit die Fuge 20 bildet.In all embodiments, the projection 18 or the projections 23 or 24 and 25 are arranged in such a way that they are at the level of the step 15, whereas the space above is kept clear by a recess 19 and the joint 20 is thus formed.
