Description

Die Erfindung betrifft einen Gerüstboden mit an seinen Enden angeordneten Verbindungselementen zur Verbindung mit einem Schnellgerüst, bestehend aus einem ein- oder mehrteiligen Hohlkastenprofil aus Metall, welches sich über die Länge des Gerüstbodens erstreckt und stirnseitig mit Abschlußelementen versehen ist, die ganz oder teilweise aus elastisch nachgiebigem Gummi oder Kunststoff bestehen und jeweils einen das Hohlkastenprofil stirnseitig überragenden Außenabschnitt sowie mindestens einen in den Hohlraum des Hohlkastenprofiles ragenden Befestigungsabschnitt aufweisen.The invention relates to a scaffolding floor with connecting elements arranged at its ends for connection to a quick scaffolding, consisting of a one-part or multi-part hollow box profile made of metal, which extends over the length of the scaffolding floor and is provided on the end face with end elements which are made entirely or partially of elastically flexible Made of rubber or plastic and each have an outer section protruding from the end of the box section and at least one fastening section projecting into the cavity of the box section.

Bei einem nach dem Stande der Technik (US-A 4 496 029) bekannten Gerüstboden der genannten Art ist der Befestigungsabschnitt des Abschlußelementes in das metallische Hohlkastenprofil mittels eines geeigneten Klebers eingeklebt. Zusätzlich kann der Außenabschnitt des Abschlußelementes mit einer aus Kunststoff bestehenden Umhüllung des Hohlkastenprofiles verschweißt sein. Diese Art der Befestigung des Abschlußelementes ist sehr herstellungsaufwendig und läßt im Hinblick auf die erforderliche Festigkeit, insbesondere Dauerfestigkeit zu wünschen übrig. Aus diesem Grunde können bei diesen Gerüstböden die an den Enden befindlichen Verbindungselemente auch nicht unmittelbar an den Abschlußelementen vorgesehen werden, sondern befinden sich an zusätzlichen U-Schienen, die ihrerseits an den Enden des Gerüstbodens befestigt sind.In a scaffold floor of the type mentioned, which is known from the prior art (US Pat. No. 4,496,029), the fastening section of the closure element is glued into the metallic hollow box profile by means of a suitable adhesive. In addition, the outer portion of the closure element can be welded to a plastic casing of the hollow box profile. This type of attachment of the end element is very expensive to manufacture and leaves something to be desired in terms of the required strength, in particular fatigue strength. For this reason, the connecting elements located at the ends of these scaffolding floors cannot be provided directly on the end elements, but are located on additional U-rails, which in turn are attached to the ends of the scaffolding floor.

Es ist deshalb Aufgabe der Erfindung, den Gerüstboden der eingangs genannten Art dahingehend weiterzubilden, daß die Dauerfestigkeit der Verbindung zwischen dem Hohlkastenprofil und den Abschlußelementen verbessert wird und der Aufwand für die Anbringung der Abschlußelemente und der Verbindungselemente verringert wird.It is therefore an object of the invention to develop the scaffolding floor of the type mentioned in such a way that the fatigue strength of the connection between the hollow box section and the end elements is improved and the effort for attaching the end elements and the connecting elements is reduced.

Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend vom Gerüstboden der eingangs genannten Art vor, daß die Abschlußelemente mit vertikal zur Ebene des Gerüstbodens verlaufenden Aufnahmeöffnungen für an dem Gerüst befindliche Haltestifte versehen sind und daß die Befestigungsabschnitte des Abschlußelementes mit dem Hohlkastenprofil durch senkrecht zur Ebene des Gerüstbodens verlaufende, eingepreßte Nieten verbunden sind, die im Befestigungsbereich des Befestigungsabschnittes von elastischem Kunststoff oder Gummi umgeben sind, wobei die lichte Weite des Hohlkastenprofiles, die Dicke des Befestigungsabschnittes und die Länge er eingepreßten Nieten so aufeinander abgestimmt sind, daß der elastisch nachgiebige Gummi oder Kunststoff des Befestigungsabschnittes im Umgebungsbereich der Nieten durch eine Verformung der Wandung des Hohlkastenprofiles unter starker elastischer Druckspannung steht.To solve this problem, the invention proposes starting from the scaffolding floor of the type mentioned that the end elements are provided with vertical openings to the level of the scaffolding floor receiving openings for retaining pins located on the scaffold and that the fastening sections of the end element with the box girder profile perpendicular to the level of the scaffolding floor running, pressed-in rivets are connected, which are surrounded in the fastening area of the fastening section by elastic plastic or rubber, the clear width of the box section, the thickness of the fastening section and the length of the pressed-in rivets are matched to one another such that the elastically flexible rubber or plastic of the Fastening section in the vicinity of the rivets is due to deformation of the wall of the hollow box profile under strong elastic compressive stress.

Diese Art der Befestigung erfordert für die Verbindung zwischen dem Hohlkastenprofil und dem Abschlußelement jeweils nur einen einzigen Preßvorgang für das Einbringen der Nieten und die geringfügige Verformung der Wandungen des Hohlkastenprofiles und ergibt einen besonders innigen und lockerungsfreien Verbund zwischen dem Abschlußelement und dem Hohlkastenprofil.This type of attachment requires only a single pressing process for the insertion of the rivets and the slight deformation of the walls of the hollow box profile for the connection between the hollow box profile and the closure element and results in a particularly intimate and looseness-free bond between the closure element and the hollow box profile.

Bei dieser Art der Befestigung erfolgt die Kraftübertragung zwischen dem Hohlkastenprofil und dem Abschlußelement auf besonders vorteilhafte Weise großflächig im Umgebungsbereich der Nieten und nicht nur im Bereich der Lochleibung der die Niete aufnehmenden Bohrungen im Hohlkastenprofil.With this type of fastening, the force transmission between the hollow box section and the end element takes place in a particularly advantageous manner over a large area in the area surrounding the rivets and not only in the area of the perforation of the bores in the box section receiving the rivets.

Durch die Anordnung der Aufnahmeöffnungen in den Abschlußelementen ergibt sich der Vorteil, daß bei in das Gerüst eingelegtem Gerüstboden die Haltekräfte großflächig verteilt auf das Hohlkastenprofil übertragen werden, ohne daß zusätzliche Schienen oder dergleichen in den Endbereichen des Gerüstbodens benötigt werden.The arrangement of the receiving openings in the end elements has the advantage that, when the scaffolding floor is inserted into the scaffolding floor, the holding forces are distributed over a large area to the hollow box profile without additional rails or the like being required in the end regions of the scaffolding floor.

Eine erste Ausführungsform sieht vor, daß die Aufnahmeöffnungen für die Aufnahme der Haltestifte des Gerüstes im Befestigungsbereich des Abschlußelementes angeordnet sind und sowohl den Befestigungsabschnitt des Abschlußelementes als auch den Endabschnitt des Hohlkastenprofiles durchdringen. Durch diese Anordnung der Aufnahmeöffnungen ergibt sich der Vorteil, daß bei in das Gerüst eingelegtem Gerüstboden die Haltekräfte direkt in dem durch den Befestigungsabschnitt des Abschlußelementes verstärkten Bereich des Hohlkastenprofiles angreifen.A first embodiment provides that the receiving openings for receiving the retaining pins of the scaffold are arranged in the fastening area of the closing element and penetrate both the fastening section of the closing element and the end section of the hollow box profile. This arrangement of the receiving openings has the advantage that when the scaffolding floor is inserted into the scaffolding, the holding forces act directly in the area of the hollow box section reinforced by the fastening section of the closure element.

Eine zweite Ausführungsform sieht vor, daß die Aufnahmeöffnungen für die Aufnahme der Haltestifte des Gerüstes im Übergangsbereich zwischen dem Außenabschnitt und dem Befestigungsabschnitt des Abschlußelementes angeordnet sind und die stirnseitigen Randbereiche des Hohlkastenprofiles durchdringen. Bei dieser Ausführungsform werden die Haltekräfte etwa in der Mitte des Abschlußelementes eingeleitet, so daß sich eine besonders gleichmäßige Verteilung der Haltekräfte über den Querschnitt des Hohlkastenprofiles ergibt.A second embodiment provides that the receiving openings for receiving the holding pins of the scaffold are arranged in the transition area between the outer section and the fastening section of the closure element and penetrate the end edge areas of the hollow box profile. In this embodiment, the holding forces are introduced approximately in the middle of the closure element, so that there is a particularly uniform distribution of the holding forces over the cross section of the hollow box profile.

Eine dritte Ausführungsform sieht vor, daß die Aufnahmeöffnungen für die Haltestifte des Gerüstes im Außenabschnitt des Abschlußelementes angeordnet sind. Bei dieser Ausführungsform kann es schlechthin nicht mehr zu einer bleibenden Verformung der Wandungen des Hohlkastenprofiles im Ansatzbereich der Haltestifte des Gerüstes kommen. Außerdem werden die Haltekräfte weitestgehend gedämpft und gleichmäßig in das Hohlkastenprofil eingeleitet.A third embodiment provides that the receiving openings for the holding pins of the frame are arranged in the outer section of the closure element. In this embodiment, there can no longer be permanent deformation of the walls of the hollow box section in the attachment area of the holding pins of the scaffold. In addition, the holding forces are largely damped and evenly introduced into the hollow box profile.

Zweckmäßig werden die Aufnahmeöffnungen für die Haltestifte jeweils von beidseitig offenen Hohlnieten gebildet oder mit einer metallischen Auskleidung versehen. Gegenüber den nach dem Stande der Technik üblichen Hohlnieten, die lediglich das Hohlkastenprofil durchdringen, haben die Hohlnieten hier den Vorteil, daß sie zusätzlich durch die unter starker Druckspannung stehende Gummi- oder Kunststoffmasse gestützt und gehalten werden, so daß die auf die Lochleibung der Bohrung im Hohlkastenprofil ausgeübten Kräfte kleiner sind und es nicht so leicht zu einer bleibenden Verformung der Wandung des Hohlkastenprofiles kommt. Die Gefahr solcher Verformungen ist gegeben, wenn der Gerüstboden versehentlich nur an einer Seite auf die Haltestifte des Gerüstes aufgesteckt wird und am anderen Ende belastet wird. Wenn die Aufnahmeöffnungen für die Haltestifte des Gerüstes in dem das Hohlkastenprofil stirnseitig überragenden Außenabschnitt des Abschlußelementes angeordnet sind, genügt es, die Aufnahmeöffnungen jeweils mit der oben erwähnten metallischen Auskleidung zu versehen, die ein Einreißen des Gummis oder Kunststoffes verhindert.The receiving openings for the holding pins are expediently formed by hollow rivets which are open on both sides or provided with a metallic lining. Compared to the conventional hollow rivets according to the prior art, which only penetrate the hollow box profile, the hollow rivets here have the advantage that they are additionally supported and held by the rubber or plastic mass under high compressive stress, so that the holes in the hole in the Hollow box profile forces are smaller and it is not so easy to permanent deformation of the wall of the hollow box profile. There is a risk of such deformations if the scaffold floor is accidentally on one side only the holding pins of the scaffold are put on and loaded at the other end. If the receiving openings for the holding pins of the scaffold are arranged in the outer section of the end element projecting above the hollow box profile, it is sufficient to provide the receiving openings with the above-mentioned metallic lining, which prevents tearing of the rubber or plastic.

Zweckmäßig sind weiterhin die äußeren Ecken der Abschlußelemente abgerundet ausgebildet. Hierdurch ist es möglich, die Gerüstböden im Gerüst mit gegebenenfalls unterschiedlichen Rahmenbreiten einzulegen. Außerdem wird durch die Abrundung die Verletzungsgefahr beim Auf- und Abbau oder beim Transport des Gerüstes vermindert.The outer corners of the end elements are also expediently rounded. This makes it possible to insert the scaffold floors in the scaffold with different frame widths, if necessary. In addition, the rounding-off reduces the risk of injury when setting up, dismantling or transporting the scaffolding.

In den Figuren 1a bis c ist das den Flächenbereich des Gerüstbodens bildende mehrteilige Hohlkastenprofil aus Aluminium mit dem Bezugszeichen 1 bezeichnet. Dieses Hohlkastenprofil 1 ist an beiden Enden (in der Zeichnung ist nur eines der Enden dargestellt) mit einem insgesamt aus gummielastischem Werkstoff hergestellten Abschlußelement 2 verbunden. Dieses Abschlußelement besteht zweckmäßig aus vulkanisiertem natürlichem oder synthetischem Kautschuk mit einer Shore-A-Härte von 80 bis 85°.In FIGS. 1a to c, the multi-part hollow box profile made of aluminum, which forms the surface area of the scaffolding floor, is designated by the reference number 1. This box girder section 1 is connected at both ends (only one of the ends is shown in the drawing) to a closure element 2 made entirely of rubber-elastic material. This closure element expediently consists of vulcanized natural or synthetic rubber with a Shore A hardness of 80 to 85 ° .

Das Abschlußelement 2 weist einen in den Innenraum des Hohlkastenprofiles 1 ragenden Befestigungsabschnitt 3 und einen das Hohlkastenprofil stirnseitig überragenden Außenabschnitt 4 auf. Der Außenabschnitt 4 fluchtet mit den äußeren Oberflächen des Hohlkastenprofiles 1 und ist an den Ecken mit großem Radius abgerundet, so daß der Gerüstboden in unterschiedlich breite Vertikalrahmen des Gerüstes eingelegt werden kann.The closure element 2 has a fastening section 3 projecting into the interior of the hollow box section 1 and an outer section 4 projecting beyond the end section of the box section. The outer section 4 is aligned with the outer surfaces of the hollow box section 1 and is rounded at the corners with a large radius, so that the scaffold floor can be inserted into vertical frames of different sizes of the scaffold.

Der Befestigungsabschnitt 3 weist drei Vorsprünge 3a, 3b und 3c auf, von denen je einer in einen Kanal 1a, 1 und 1 des Hohlkastenprofiles 1 ragt. Hierdurch ist es möglich, die Stege zwischen den Kanälen 1 a, 1 b und 1 c fast bis an das stirnseitige Ende des Hohlkastenprofiles stehenzulassen (vergleiche Figur 1 b). Da bei dem Ausführungsbeispiel der Figuren 1a bis c das Hohlkastenprofil 1 bis in den Bereich der abgerundeten Ecken des Abschlußelementes 2 reicht, sind hier die Ecken des Hohlkastenprofiles 1 entsprechend abgerundet, so daß der Außenabschnitt 4 auch im Bereich der Ecken etwa die gleiche Breite hat wie an der Stirnseite des Gerüstbodens.The fastening section 3 has three projections 3a, 3b and 3c, one of which projects into a channel 1a, 1 and 1 of the hollow box section 1. This makes it possible to leave the webs between the channels 1 a, 1 b and 1 c almost up to the front end of the hollow box section (see FIG. 1 b). Since in the embodiment of FIGS. 1a to c the hollow box section 1 extends into the area of the rounded corners of the end element 2, the corners of the box section 1 are correspondingly rounded here, so that the outer section 4 also has approximately the same width in the area of the corners as at the front of the scaffold floor.

In den Vorsprüngen 3a, 3b und 3c des Befestigungsabschnittes 3 des Abschlußelementes 2 sowie im Endabschnitt des Hohlkastenprofiles 1 befinden sich Löcher, die zur Aufnahme von Nieten 5a und 5b dienen.There are holes in the projections 3a, 3b and 3c of the fastening section 3 of the closure element 2 and in the end section of the hollow box profile 1, which serve to receive rivets 5a and 5b.

Zur Befestigung des Abschlußelementes 2 an dem Hohlkastenprofil 1 wird zunächst der Endabschnitt des Hohlkastenprofiles 1 durch Abrunden der Ecken und Heraustrennen der Stege zwischen den Kanälen 1a, 1 und 1 so vorbereitet, wie aus Fig. 1 ersichtlich ist. Dann wird das Abschlußelement 2 mit seinem Befestigungsabschnitt 3 in das Ende des Hohlkastenprofiles 1 derart eingesteckt, daß die Löcher im Hohlkastenprofil 1 und Befestigungsabschnitt 3 fluchten. Dann werden in diese Löcher die Nieten. 5a und 5b eingeführt und mittels einer Nietpresse verpreßt. Dabei sind die Längen der Nieten 5a und 5b, die Dicke des Befestigungsabschnittes 3 und die lichte Weite des Hohlkastenprofiles 1 so aufeinander abgestimmt, daß beim Einpressen der Nieten 5a und 5b die oberen und unteren Wandungen des Hohlkastenprofiles 1 derart nach innen verformt werden, daß das gummielastische Material des Befestigungsabschnittes 3 in der Umgebung der Nieten 5a und 5b großflächig unter eine starke elastische Druckspannung versetzt wird. Hierdurch ergeben sich ein guter Halt und ein inniger Verbund zwischen dem Hohlkastenprofil 1 und dem Befestigungsabschnitt 3 des Abschlußelementes 2.To fasten the closure element 2 to the hollow box section 1, the end section of the hollow box section 1 is first prepared by rounding off the corners and separating the webs between the channels 1a, 1 and 1, as can be seen from FIG. 1. Then the closing element 2 with its fastening section 3 is inserted into the end of the hollow box section 1 such that the holes in the hollow box section 1 and fastening section 3 are aligned. Then the rivets are in these holes. 5a and 5b introduced and pressed by means of a rivet press. The lengths of the rivets 5a and 5b, the thickness of the fastening section 3 and the inside width of the hollow box section 1 are coordinated with one another in such a way that when the rivets 5a and 5b are pressed in, the upper and lower walls of the hollow box section 1 are deformed inwards such that the rubber-elastic material of the fastening section 3 in the vicinity of the rivets 5a and 5b is placed over a large area under a strong elastic compressive stress. This results in a good hold and an intimate bond between the hollow box section 1 and the fastening section 3 of the end element 2.

Die beiden äußeren Niete 5a sind beim Ausführungsbeispiel der Figuren la bis c als nach beiden Seiten offene Hohlniete ausgebildet. Die Öffnungen dieser Hohlniete 5a dienen zugleich als Aufnahmeöffnungen 6 für die Aufnahme der Haltestifte des Gerüstes, die in der Zeichnung nicht näher dargestellt sind.The two outer rivets 5a are formed in the embodiment of Figures la to c as hollow rivets open on both sides. The openings of these hollow rivets 5a also serve as receiving openings 6 for receiving the holding pins of the frame, which are not shown in the drawing.

Das Ausführungsbeispiel der Figuren 2a bis c entspricht weitgehend dem Ausführungsbeispiel der Figuren 1a bis c, so daß für die einander entsprechenden Teile die gleichen Bezugszeichen verwendet werden können. Hier ist jedoch der Au-Benabschnitt 4 des Abschlußelementes 2 breiter ausgebildet, so daß eine Abrundung der Ecken des Hohlkastenprofiles 1 entfallen kann. Außerdem beginnen hier die Vorsprünge 3a, 3b und 3c des Befestigungsabschnittes 3 im Bereich der Grenzfläche zwischen dem Befestigungsabschnitt 3 und dem Au- βenabschnitt 4. Aus diesem Grunde können die Stege zwischen den Kanälen 1a, 1 b und 1 c des Hohlkastenprofiles 1 bis an das Ende des Hohlkastenprofiles 1 stehenbleiben. Das Holkastenprofil benötigt bei dieser Ausführungsform insofern weniger Bearbeitung, als bei der Ausführungsform nach den Figuren 1 a bis c.The embodiment of Figures 2a to c largely corresponds to the embodiment of Figures 1a to c, so that the same reference numerals can be used for the corresponding parts. However, here is the Ben section 4 of the end element 2 is wider so that rounding of the corners of the hollow box section 1 can be omitted. In addition, the projections 3a, 3b and 3c of the fastening section 3 begin here in the region of the interface between the fastening section 3 and the outer section 4. For this reason, the webs between the channels 1a, 1b and 1c of the hollow box section 1 can reach up to that Stop the end of the box girder section 1. In this embodiment, the holster profile requires less processing than in the embodiment according to FIGS. 1 a to c.

Weiterhin sind beim Ausführungsbeispiel nach den Figuren 2a bis c die die Aufnahmeöffnungen 6 für die Befestigungszapfen des Gerüstes bildenden Hohlniete 5a im Ubergangsbereich zwischen dem Außenabschnitt 4 und dem Befestigungsabschnitt 3 des Abschlußelementes 2 angeordnet. Dementsprechend ist der Endabschnitt des Hohlkastenprofiles 1 bei diesem Ausführungsbeispiel nicht nur mit Löchern zur Aufnahme der Nieten 5b, sondern auch mit halbkreisförmigen Ausnehmungen an der Stirnseite zur Aufnahme der Hohlnieten 5a versehen.Furthermore, in the exemplary embodiment according to FIGS. 2a to c, the hollow rivets 5a forming the receiving openings 6 for the fastening pins of the framework are arranged in the transition region between the outer section 4 and the fastening section 3 of the closure element 2. Accordingly, the end section of the hollow box section 1 in this exemplary embodiment is not only provided with holes for receiving the rivets 5b, but also with semicircular recesses on the end face for receiving the hollow rivets 5a.

Das Ausführungsbeispiel der Figuren 3a bis 3c entspricht weitestgehend dem Ausführungsbeispiel der Figuren 2a bis c. Hier befinden sich jedoch die Aufnahmeöffnungen 6 für die nicht dargestellten Haltestifte des Gerüstes im Außenabschnitt 4 des Abschlußelementes 2. Dementsprechend sind hier keine Hohlniete 5a zur Verbindung zwischen dem Hohlkastenprofil 1 und dem Abschlußelement 2 notwendig. In den Aufnahmeöffnungen für die Haltestifte des Gerüstes sind allerdings auch bei diesem Ausführungsbeispiel zweckmäßig metallische Auskleidungen 7 vorgesehen, die ein Einreißen des gummielastischen Materials verhindern. Wie aus Figur 3b ersichtlich ist, ist bei dem zuletzt genannten Ausführungsbeispiel der Bearbeitungsaufwand am Endabschnitt des Hohlkastenprofiles 1 am geringsten.The exemplary embodiment in FIGS. 3a to 3c largely corresponds to the exemplary embodiment in FIGS. 2a to c. Here, however, there are the receiving openings 6 for the retaining pins of the scaffold, not shown, in the outer section 4 of the closure element 2. Accordingly, no hollow rivets 5a are necessary here for the connection between the hollow box section 1 and the closure element 2. In this exemplary embodiment, metallic linings 7 are also provided in the receiving openings for the holding pins of the framework, which prevent the rubber-elastic material from tearing. As can be seen from FIG. 3b, the processing effort at the end section of the hollow box section 1 is lowest in the last-mentioned exemplary embodiment.
