Description

Die Erfindung bezieht sich auf eine Anordnung an Doppelböden mit zur eckseitigen Auflage auf Kopfplatten von Säulen dienenden, mehrschich­tigen Doppelbodenplatten.The invention relates to an arrangement of raised floors with multilayer raised floor panels serving for corner support on head plates of pillars.

Die Mehrschichtigkeit resultiert aus einer meist metallenen Wanne, einer Schicht armierten Betons darin und der Begehungsschicht. Letztere besteht aus einer Bodenbelagsschicht. Solche, auf Säulen ruhenden, den Oberboden bildenden Doppelbodenplatten liegen in einem so großen Abstand zum sogenannten Unterboden, daß der Zwischenraum zur ver­deckten Führung von bspw. Heizungsrohren, Elektroleitungen etc. ge­nutzt werden kann. Diesem anerkannten Vorteil steht jedoch der Nachteil entgegen, daß die Doppelbodenplatten in der Bauphase noch eine zeitlang dem rauhen Baubetrieb ausgesetzt sind; Beschädigungen bzw. bleibende Verunreinigungen sind daher nicht auszuschließen.The multilayered structure results from a mostly metal tub, a layer of reinforced concrete in it and the inspection layer. The latter consists of a layer of flooring. Such double floor panels resting on pillars and forming the upper floor are so far apart from the so-called underbody that the intermediate space can be used for the concealed guidance of, for example, heating pipes, electrical lines, etc. However, this recognized advantage is offset by the disadvantage that the raised floor panels are still exposed to the rough construction work for a while; Damage or permanent contamination cannot be ruled out.

Aufgabe der Erfindung ist es, eine gattungsgemäße Anordnung zu schaffen, die in der Phase der Bauzeit den Nutzen des Hohlbodens hat, bei der aber die den eigentlichen Laufboden bildende Bodenbe­lagsschicht nicht beeinträchtigt wird, dies bei hochstabiler Zuordnung der die Distanz zum Unterboden bringenden Elemente.The object of the invention is to provide a generic arrangement which has the benefit of the hollow floor in the phase of the construction period, but in which the floor covering layer forming the actual walking floor is not impaired, this with highly stable assignment of the elements bringing the distance to the sub-floor.

Gelöst ist diese Aufgabe durch die in den Ansprüchen 1 und 3 ange­gebene Erfindung.This object is achieved by the invention specified in claims 1 and 3.

Die Unteransprüche sind vorteilhafte Weiterbildungen der erfindungs­gemäßen Anordnung.The subclaims are advantageous developments of the arrangement according to the invention.

Zufolge solcher Ausgestaltung ist ein gattungsgemäßes Doppelboden­system von erhöhtem Gebrauchswert erzielt: Die gesamte Doppelbo­den-Tragkonstruktion kann zunächst völlig fertiggestellt werden. Ihren provisorischen Oberabschluß bildet dabei die unterste, auf Säulen aufliegende Schicht, welche als Gitterrost realisiert ist. Je nach der Maschendichte solcher Gitterroste ist diese lattungsartige Schicht unmittelbar begehbar. Bei größeren Gitterrost-Aussparungen werden einfach die am Bau ohnehin vorhandenen Bohlen, Schalbretter oder dergleichen aufgelegt. Der Hohlraum it so jederzeit und von jedem Punkt aus erreichbar. Hierzu wird einfach eine oder andere der Gitterroste ausgehoben. Bei der entsprechenden Durchgriffmöglichkeit stellt dies überhaupt kein Problem dar. Die restlichen Gitterroste verbleiben in stabilem Tragverbund zu den Säulen. Die diesbezügliche Zuordnung ist vorteilhaft dadurch gelöst, daß jedes Gitterrost eine zentrale ringsgeschlossene Öffnung, ferner randseitige, entsprechende Halböffnungen und eckseitig entsprechende Viertelöffnungen zum Eintritt je eines Zentrierzapfens der Säulenkopfplatte besitzt, und welches überdeckt ist von einer flächengeschlossenen Begehungsplatte, deren Umriß die Öffnungen ganz bzw. anteilig mit den benachbarten Begehungsplatten abdeckt. Letztere werden erst aufgelegt, wenn alle Arbeiten abgeschlossen sind. Bilden sie den oberen Abschluß des Oberbodens, also wird keine Estrichschicht oder dergleichen mehr aufgetragen, so verbleibt der Vorteil der jederzeitigen, einfachsten In­spektion bzw. Revision an jeder Stelle. Zufolge der Gitterstruktur der Zwischenschicht entstehen auch keine Nachteile für das ebenengerechte Zuordnen der Begehungsplatten, da noch anfallender Bau- bzw. Mon­tageschutt durch das Gitter hindurchfällt. Größere Stücke dagegen können leicht abgenommen werden. So fällt dem Gitterrost sogar zusätzlich Siebfunktion zu. Die Begehungsplatten sind hochstabil, wenngleich auch auf materialersparende Maßnahmen geachtet ist, welche darin bestehen, daß die Begehungsplatte an ihrer Unterseite diagonal verlaufende Stabilisierungsrippen besitzt, die von einer entsprechenden Randrahmenrippe ausgehen. Eine andere vorteilhaft Lösung der erfindungsgemäßen Aufgabe besteht darin, daß die unterste, auf den Säulen aufliegende Schicht als Gitterrost gestaltet ist, welches Öff­nungen gesitzt zum Eintritt je eines Zentrierzapfens der Säulen-­Kopfplatte, überdeckt ist von einer flächengeschlossenen Bege­ hungsplatte, deren Umriß die Öffnungen abdeckt, wobei die Kopfplat­ten der Säulen mit Segmenten formschlüssig in die Bereiche rückseitig der Öffnungen des Gitterrostes eingreifen. Neben den bereits erör­terten Vorteilen zu Anspruch 1 tritt bezüglich der Säulen-Kopfplatte noch der eines klauenkupplungsartigen, drehgesicherten, horizontal sperrenden Eingriffs dieser Säulenplatte in das Gitterwerk der als Gitterrost gestalteten Schicht auf, die selbst somit das formpassende Gegenkupplungselement darstellt. In den Eckzonen werden dabei vier Gitterroste aneinander gefesselt. Das Gitterrost ist so optimal posi­tioniert. Seine Hanglast selbst sichert schon diese Verbindung, die den im rauhen Baubetrieb auftretenden Belastungen voll gewachsen ist. In einfacher Weise sind die Öffnungen jeweils von einem entsprechend ge­bogenen Verlauf der Gitterroststege gebildet. Dies bringt eine gün­stigst nutzbare Seitenabstützung. Für eine allseitig fortsetzbare Gitterung erweist es sich weiter als vorteilhaft, daß die ganze Kopf­platte in Segmente unterteilt ist. Letztere liegen winkelverteilt zur Längsmittelachse der Säule. Schließlich erweist es sich noch als Vor­teil, daß die Kopfplatte nur mit einem Teil ihrer Dicke in unterseitigen Aussparungen des Gitterwerks einliegt. Die Kopfplatte kommt so nicht mit der Begehungsplatte in Berührung. Letztere liegt folglich plan auf dem Gitter auf. Für eine exakte Nivellierung der Doppelboden-Trag­konstruktion erweist es sich endlich als vorteilhaft, daß im Zentrier­zapfen ein mit einer kopfseitigen Werkzeugangriffsfläche ausgestattetes Längenverstellglied der Säule angeordnet ist. Auch kann die Ver­stellung zufolge der oberseitigen Lage entsprechend einfach erfolgen. Die Verstellstellen werden erst durch Auflegen der Begehungsplatten verschlossen.As a result of such a design, a generic double floor system of increased utility value is achieved: the entire double floor support structure can initially be completely completed. Your provisional upper degree forms the bottom, on Layer on top of pillars, which is realized as a grating. Depending on the mesh density of such gratings, this lath-like layer can be walked on directly. In the case of larger grating recesses, the planks, formwork boards or the like which are already present on the construction are simply placed on top. The cavity can thus be reached at any time and from any point. To do this, one or the other of the gratings is simply lifted out. With the appropriate reach-through option, this is not a problem at all. The remaining gratings remain in a stable supporting connection to the columns. The assignment in this regard is advantageously achieved in that each grating has a central ring-closed opening, furthermore, corresponding half openings on the edge and corresponding quarter openings on the corner side for the entry of one centering pin each of the column head plate, and which is covered by a surface-closed inspection plate, the outline of which completely or partially covered with the neighboring inspection boards. The latter will only be launched when all work has been completed. If you form the upper end of the top floor, i.e. no screed layer or the like is applied anymore, the advantage of the simplest inspection or revision at any time remains at every point. As a result of the lattice structure of the intermediate layer, there are also no disadvantages for the level assignment of the inspection boards, since building or assembly rubble still falls through the lattice. Larger pieces, on the other hand, can easily be removed. The grating even has an additional sieve function. The inspection plates are highly stable, although attention is also paid to material-saving measures, which consist in the fact that the inspection plate has diagonally extending stabilizing ribs on its underside, which emanate from a corresponding edge frame rib. Another advantageous solution to the problem of the invention is that the lowest layer resting on the columns is designed as a grating, which has openings for the entry of a centering pin each of the column head plate, is covered by a closed area hungsplatte, the outline of which covers the openings, the head plates of the columns with segments engage positively in the areas on the back of the openings of the grating. In addition to the advantages of claim 1 already discussed, with regard to the column head plate, there is also a claw coupling-like, rotationally secured, horizontally locking engagement of this column plate in the lattice work of the layer designed as a grating, which thus itself represents the form-fitting mating coupling element. Four gratings are tied together in the corner zones. The grate is optimally positioned. Its slope load itself already secures this connection, which is fully able to withstand the stresses encountered in rough construction operations. The openings are each formed in a simple manner by a correspondingly curved profile of the grating webs. This provides the cheapest possible side support. For a lattice that can be continued on all sides, it also proves advantageous that the entire top plate is divided into segments. The latter lie at an angle to the longitudinal central axis of the column. Finally, it proves to be an advantage that the head plate lies only with a part of its thickness in recesses on the underside of the latticework. The head plate thus does not come into contact with the inspection plate. The latter consequently lies flat on the grid. For an exact leveling of the raised floor support structure, it finally proves to be advantageous that a length adjustment member of the column, which is equipped with a head-side tool engagement surface, is arranged in the centering pin. The adjustment can also be carried out in a correspondingly simple manner due to the top position. The adjustment points are only closed when the inspection boards are put on.

Die erfindungsgemäße Anordnung zur Schaffung eines Hohlraumes H zwischen Oberboden I und Unterboden II besteht aus Säulen 1, Git­terrosten 2 und Begehungsplatten 3. Dieser mehrschichtige Aufbau ergibt sich aus Fig. 7.The arrangement according to the invention for creating a cavity H between top floor I and bottom floor II consists of columns 1, gratings 2 and inspection boards 3. This multilayer structure is shown in FIG. 7.

Die Begehungsplatte 3 ist quadratischen Grundrisses, etwa in den Ab­messungen von 0,6 x 0,6 m. Sie ist als armierte Betonplatte reali­siert, kann aber auch aus Holz, Kunstholz oder dergleichen bestehen. Die Dicke ist in den plattenüblichen Maßen von ca. 2 - 5 cm gehalten. Zur Stabilisierung weist die Begehungsplatte an ihrer Unterseite dia­gonal verlaufende Stabilisierungsrippen 3ʹ auf; letztere gehen von einer ebenfalls unterseitig verlaufenden Randrahmenrippe 3ʺ aus. Beide Rippen sind von gleicher Höhe entspricht etwa der halben Begehungsplatten-Dicke.The inspection board 3 is square in plan, approximately in the dimensions of 0.6 x 0.6 m. It is realized as a reinforced concrete slab, but can also consist of wood, synthetic wood or the like. The thickness is kept in the usual plate dimensions of approx. 2 - 5 cm. For stabilization, the inspection plate has diagonal stabilizing ribs 3ʹ on its underside; the latter assume an edge frame rib 3ʺ also running on the underside. Both ribs are of the same height, which corresponds to about half the thickness of the inspection board.

Das Gitterrost 2 ist im Grunde ebenfalls quadratischen Grundrisses gleicher Seitenabmessungen. Seine Seiten fluchten -bis auf kleinere Zonen, die der Säulenzuordnung dienen- mit denen der Begehungs­platte 3. Das Gitterrost 2 ist geviertelt zufolge kreuzförmig verlau­fender Gitterroststege 4, die parallel zu einen geschlossenen Rahmen R schaffenden, randseitigen Gitterroststegen 5 verlaufen.The grating 2 is basically also a square floor plan of the same side dimensions. Its sides are aligned - except for smaller zones, which are used for column assignment - with those of the inspection plate 3. The grating 2 is quartered according to the cross-shaped grating bars 4, which run parallel to a closed frame R creating grating bars 5 on the edge.

Die in Richtung des Zentrums der Platte laufenden Enden 4ʹ der Git­terroststege 4 umschreiben eine ringsgeschlossene, kreisrunde Öffnung 6. Die in Richtung der den Rahmen R bildenden Gitterroststege 5 verlaufenden Enden 4ʺ formen eine durchmesserentsprechende, rand­seitige nach außen hin offene Halböffnung 6ʹ. In den Eckbereichen laufen die rahmenbildenden Gitterroststege 5 in einer Weise zusammen, daß dort eine nach außen offene Viertelöffnung 6ʺ entsteht. AUch deren Öffnungskonturen sowie deren Stegrücken sind kreisrund ver­laufend, jedoch mit im Umriß der Seitenlinien der bzw. des Gitterrostes 2 liegendem Radiuspunkt (Fig. 2).The ends 4ʹ of the grating webs 4 running in the direction of the center of the plate circumscribe an annularly closed, circular opening 6. The ends 4ʺ running in the direction of the grating webs 5 forming the frame R form a diameter-appropriate, half-opening 6ʹ open to the outside on the edge. In the corner areas, the frame-forming grating webs 5 converge in such a way that there is a quarter opening 6ʺ open to the outside. Also their opening contours and their ridges are circular, but with a radius point lying in the outline of the side lines of the grating 2 (Fig. 2).

Die auf die Seitenmitte des quadratischen Grundrisses ausgerichteten Gitterroststege 4 besitzen die zweifache Dicke der rahmenbildenden Gitterroststege 5. Die öffnungsumschreibenden Wölbungsabschnitten 5ʹ sind so dick wie die letzteren. Die Höhe der sämtlich rechteckigen Querschnitt aufweisenden, mit der größeren Querschnittslänge vertikal ausgerichteten Gitterroststege 4 und 5 entspricht der zwei- bis vier­fachen Breite der Gitterroststege 4. Die die zentrale Öffnung 6 rah­menden Wölbungsabschnitte 4‴ besitzen eine den anderen Wölbungs­abschnitten 5ʹ genau entsprechende Dicke.The grating webs 4 aligned with the center of the side of the square floor plan have twice the thickness of the frame-forming grating webs 5. The opening-circumscribing sections 5ʹ are as thick as the latter. The height of the grating webs 4 and 5, which all have a rectangular cross section and are vertically oriented with the greater cross-section length, corresponds to two to four times the width of the grating webs 4. The arching sections 4 ‴ framing the central opening 6 have a thickness which corresponds exactly to that of the other arching sections 5ʹ.

Die schachbrettartig in zwei Dimensionen aneinandergereihten Gitter­roste 2 ruhen formschlüssig in Kopfplatten 7 der Säulen 1. Jede Kopfplatte 7 weist dazu oberseitig eine der Breite der Gitterroststege 4 bzw. 5 angepaßt Kreuznutung 8 auf, bestehend aus radial weisenden Nutabschnitten 8ʹ und zentral aus dem Wölbungsverlauf der öffnungs­umschreibenden Wölbungsabschnitten 4‴ bzw. 5ʹ entsprechenden Nut­abschnitten 8ʺ. Die Nutabschnitte 8ʹ erstrecken sich in gleichen Winkelabständen zueinander. Die Tiefe der Kreuznutung 8 entspricht im wesentlichen der halben Steghöhe. Zufolge der Kreuznutung ver­bleiben an einer kreisförmigen Grundriß aufweisenden Kopfplatte ring­abschnittförmige Segmente 9. Die Kopfplatte 7 greift nur mit einem Teil ihrer Dicke, d. h. nur mit den Segmenten 9 in die eckseitigen Aussparungen 10 des Gitterwerks ein.The grids 2, which are lined up in two dimensions like a checkerboard, rest positively in head plates 7 of the columns 1. Each For this purpose, the top plate 7 has a cross groove 8 adapted to the width of the grating webs 4 and 5, consisting of radially pointing groove sections 8ʹ and centrally from the curvature of the opening-circumscribing arch sections 4 4 and 5ʹ corresponding groove sections 8ʺ. The groove sections 8ʹ extend at equal angular intervals from one another. The depth of the cross groove 8 corresponds essentially to half the web height. As a result of the cross-groove, segments 9 in the form of ring sections remain on a head plate having a circular plan. The head plate 7 engages only with part of its thickness, ie only with the segments 9, in the corner-side recesses 10 of the latticework.

Die im Zentrum des Gitterrostes 2 liegende Öffnung 6 umschließt einen ebenfalls oberseitig der Kopfplatte 7 der Säule 1 ausgehenden Zentrier­zapfen 12 ganz, im Mittelbereich der Seiten hälftig und in den Eck­bereichen je mit einem Viertel. Der Zentrierzapfen 12 ist zylindrisch gestaltet und liegt konzentrisch zur ihn umgebenden, aus den Nut­abschnitten 8ʺ gebildeten Ringnut.The opening 6 located in the center of the grating 2 completely encloses a centering pin 12 also extending on the top side of the head plate 7 of the column 1, half in the central region of the sides and one quarter each in the corner regions. The centering pin 12 is cylindrical and is concentric with the surrounding annular groove formed by the groove sections 8ab.

Der Zentrierzapfen 12 schließt oberseitig ebenengleich mit den Seg­menten 9 ab. Ein diese jedoch oberseitig überragender Überstand hätte den Vorteil einer voreilenden Steckverbindung; über den ent­sprechend vorspringenden Zentrierzapfen 12 erfolgt dann die Haupt­ausrichtung der Säule 1; es bedarf dazu nur noch des korrigierenden Verdrehens um die Längsmittelachse der rotationssymmetrischen Säule, bis die Nutabschnitte 8ʹ deckungsgleich zu den Gitterroststegen 4 bzw. 5 liegen, die dann zufolge ihrer Eigenlast in die Kreuznutung 8 ein­rücken. Die Kopfplatte ist praktisch wie eine Klauenkupplung rea­lisiert, deren Gegenkupplungsteil die zugehörige Gitterstruktur des bzw. der Gitterroste 2 bildet.The centering pin 12 is flush with the segments 9 on the top side. A protrusion protruding from the top would have the advantage of a leading plug connection; The main alignment of the column 1 then takes place via the corresponding projecting centering pin 12; all that is required is corrective twisting about the longitudinal central axis of the rotationally symmetrical column until the groove sections 8ʹ are congruent with the grating webs 4 and 5, which then move into the cross groove 8 due to their own load. The top plate is practically implemented like a claw coupling, the counter coupling part of which forms the associated grating structure of the grating (s) 2.

Wie ersichtlich, ist die ganze Kopfplatte 7 in Segmente 9 eingeteilt, und zwar beim Ausführungsbeispiel in vier Teile. Würde ein hexa­ gonaler Gitterrost-Grundriß zugrundeliegen, wären entsprechend drei radial ausgerichtete Nutabschnitte 8ʹ mit dann drei Segmenten zu realisieren. Der Segmenteingriff in die Aussparungen 10 führt zu einem exakten Verbund mit fester Rand-an-Rand-Anlage der einzelnen Git­terroste 2. Letztere können nicht verrutschen. Selbst wenn aus Gründen einer Inspektion eines der Gitterroste 2 später aus dem Verbund herausgelöst würde, was durch einfaches Nachobenziehen eines Gitterrostes 2 erfolgen könnte, wäre das Wandern benachbarter Platten in der Horizontalen nicht möglich auch zufolge Abstützung derselben an der Mantelwand des Zentrierzapfens 12.As can be seen, the entire head plate 7 is divided into segments 9, in the embodiment in four parts. Would be a hexa on the basis of the horizontal grid plan, three radially aligned groove sections 8ʹ with then three segments would have to be realized accordingly. The segmental engagement in the recesses 10 leads to an exact bond with a fixed edge-to-edge contact of the individual gratings 2. The latter cannot slip. Even if one of the gratings 2 would later be released from the assembly for inspection purposes, which could be done by simply pulling a grating 2 upwards, it would not be possible for adjacent plates to move horizontally, even if they were supported on the lateral wall of the centering pin 12.

Die Säulen 1 sind längenveränderbar und dazu mit einer Schraub­spindel als Längenverstellglied 13 ausgerüstet. Dessen Gewinde steht in Eingriff mit einem Gegengewinde 14 des hülsenförmigen Säulen­schaftes 15, welcher oberseitig über einen Kegelstumpfabschnitt 16 in die kreisrunde Kopfplatte 7 der Säule 1 übergeht.The columns 1 can be changed in length and are equipped with a screw spindle as the length adjustment member 13. Its thread is in engagement with a counter thread 14 of the sleeve-shaped column shaft 15, which merges on the upper side via a truncated cone section 16 into the circular head plate 7 of the column 1.

Das untere, d. h. dem Unterboden 11 als Aufstellfläche zugewandte Ende des Säulen-Verstellgliedes 13 geht in eine Fußplatte 17 über. Letztere ist ebenfalls kreisförmigen Zuschnitts, und zwar etwa im Durchmesser der Kopfplatte 7 gehalten, und läuft zentral in einen kegelstumpfförmigen Sockel 17ʹ aus, von welchem die nach oben wei­sende Schraubspindel ausgeht.The lower, i.e. H. the bottom of the column-adjusting member 13 facing the base 11 as a mounting surface merges into a base plate 17. The latter is also circular blank, approximately in the diameter of the head plate 7, and runs centrally into a truncated cone-shaped base 17 ', from which the upward-pointing screw spindle extends.

Das Gegengewinde 14 erstreckt sich über die gesamte axiale Länge des Säulenschaftes 15 und durchsetzt überdies auch zentral den Zentrier­zapfen 12. Zur Justierung der Säule, d. h. Nivellierung der Auflage­ebene für die die untere Schicht bildenden Gitterroste 2, weist das kopfseitige Ende des Làngenverstellgliedes 13 eine Werkzeug-Angriffs­fläche 18 auf. Es kann sich hier um einen Querschlitz zum Einsetzen der Klinge eines Schraubendrehers handeln.The counter thread 14 extends over the entire axial length of the column shaft 15 and also penetrates centrally through the centering pin 12. To adjust the column, i. H. Leveling the support plane for the gratings 2 forming the lower layer, the head-side end of the length adjustment member 13 has a tool engagement surface 18. This can be a transverse slot for inserting the screwdriver blade.

Durch Auflegen der flächengeschlossenen Begehungsplatten 3, deren Umriß die Öffnungen 6ʹ, 6ʺ anteilig mit den benachbarten Begehungs­platten 3 abdeckt, ist auch die Verstellzugänglichkeit aufgehoben. Es wird auf die Darstellung in Fig. 8 verwiesen, wo dieser Zustand zum Teil schon verwirklicht ist. Sobald die anderen beiden Begehungs­platten 3 aufgelegt sind, ist die Zugänglichkeit ganz aufgehoben.By placing the closed inspection boards 3, whose Outline covers the openings 6ʹ, 6ʺ proportionally with the adjacent inspection boards 3, the adjustment accessibility is also eliminated. Reference is made to the illustration in FIG. 8, where this state has already been partially achieved. As soon as the other two inspection boards 3 have been placed on them, accessibility is eliminated.

Ergibt sich die Notwendigkeit einer späteren Zugänglichkeit für den Hohlraum H, so kann dann durch Aufsetzen eines Saugnapfes auf die glatte Oberfläche der Begehungsplatte 3 diese ausgehoben werden. Die anderen können dann durch Untergriff der benachbarten Platten durch die geschaffene Öffnung hindurch leicht entfernt werden.If there is a need for later access to the cavity H, a suction cup can then be lifted onto the smooth surface of the inspection plate 3. The others can then be easily removed by grasping the adjacent plates through the created opening.

Ein Eigenverdrehen der Kopfplatte 7 scheidet aus zufolge des Kupp­lungseingriffs mit der Gitterrost-Schicht. Die Fußplatte 17 sitzt da­gegen nur reibungsschlüssig auf der Oberseite der Unterdecke 11 auf.A self-twisting of the head plate 7 is ruled out due to the clutch engagement with the grating layer. The foot plate 17, however, sits only frictionally on the top of the false ceiling 11.

Die vier Schmalrandflächen der Begehungsplatte 3 erstrecken sich im rechten Winkel, also senkrecht zur Begehungsfläche der Platte. Die Unterseite der Rahmenrandrippe 3ʺ und die der Stabilisierungsrippen 3ʹ verläuft parallel zur Begehungsfläche. In den Ecken der Bege­hungsplatte laufen die Rippen 3ʹ, 3ʺ dreistrahlig zusammen, so daß dort eine pfeilkopfartige, relativ flächengroße Zone maximaler Dicke vorliegt für die stabile säulenseitige Abstützung. Die Breite der Rippen 3ʹ, 3ʺ entspricht dem ca. Vierfachen der Breite der Stege 4, 5.The four narrow edge surfaces of the inspection plate 3 extend at a right angle, that is to say perpendicular to the inspection surface of the plate. The underside of the frame edge rib 3ʺ and that of the stabilizing ribs 3ʹ runs parallel to the inspection area. In the corners of the inspection plate, the ribs 3ʹ, 3ʺ converge in three rays, so that there is an arrowhead-like, relatively area-sized zone of maximum thickness for stable column-side support. The width of the ribs 3ʹ, 3ʺ corresponds to approximately four times the width of the webs 4, 5.

Alle in der Beschreibung erwähnten und in der Zeichnung dargestell­ten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All the new features mentioned in the description and shown in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
