Abstract

A connecting device is provided for a bearing bar consisting of a tube having such a connecting device at each of its two ends. The connecting device may be used to join horizontal and vertical scaffolding elements. The connecting device consists of a bearing head and a clamping device and is of such a design that its top edge lies in a plane with that of the tube attached thereto. In addition, the connecting device has bolts for a non-positive connection with overlying elements suspendable thereover. These constructional features of the connecting device allow the overlying elements, which have holes or eyelets to be pushed over the bolts of the bearing bar for suspending in the scaffold, to be placed close up to the post elements, so that virtually no gap between the overlying element and the post element is formed. Moreover, the length of the bearing bars may be dimensioned in such a way that frame scaffoldings and modular scaffoldings can be combined as result of an identically adjustable axial spacing of the pair of posts of a modular scaffolding with respect to the axial spacing of a frame scaffolding.

Description

Verbindungsvorrichtung eines AufiageriegelsConnection device of a support bar
Die vorliegende Erfindung betrifft eine Verbindungvorrichtung bzw einen Auflageπegel, der aus einem Rohr mit jeweils einer solchen Verbindungsvorrichtung an den beiden Enden besteht. Mit der Verbindungsvorrichtung können horizontale und vertikale Gerüstelemente miteinander verbunden werden Die Verbindungsvorrichtung besteht aus einem Auflagekopf und einer Klemmvorrichtung und ist so ausgebildet, daß ihre Oberkante mit der des daran befestigten Rohrs auf einer Ebene ist. Femer weist die Verbindungsvorrichtung Bolzen zur kraftschlussigen Verbindung mit darüber einhängbaren Belägen auf Durch diese konstruktiven Merkmale der Verbindungsvorrichtung ist es möglich, Belage mit Lochern oder Ösen, die zum Einhängen in das Gerüst über die Bolzen der Auflageriegel geschoben werden, bis an die Ständerelemente heranzulegen, so daß nahezu kein Spalt zwischen Belag und Ständerelement entsteht Darüberhinaus können die Auflageπegel in ihrer Länge so bemessen werden, daß auf Grund eines identisch einstellbaren Achsabstands der Ständerpaare eines Modulgerüstes zu dem Achsabstand eines Rahmengerύstes, Rahmen- und Modulgerüste miteinander kombiniert werden könnenThe present invention relates to a connecting device or a support which consists of a tube, each with such a connecting device at the two ends. With the connecting device, horizontal and vertical scaffolding elements can be connected to one another. The connecting device consists of a support head and a clamping device and is designed such that its upper edge is at one level with that of the tube attached to it. Furthermore, the connecting device has bolts for non-positive connection with coverings which can be suspended above it.Through these structural features of the connecting device, it is possible to lay coverings with holes or eyelets which are pushed over the bolts of the support bolts for hanging into the framework, as far as the stand elements that there is almost no gap between the covering and the stand element. Furthermore, the length of the supports can be dimensioned in such a way that, due to an identical adjustable center distance of the stand pairs of a module frame to the center distance of a frame frame, frame and module frames can be combined with one another
Im Zuge zunehmender Arbeitssicherheitsvorschriften kommen Arbeitsgerüsten eine immer großer Bedeutung zu Neben einer schnellen Montierbarkeit, werden bei Gerüsten hauptsachlich hohe Anforderungen an die Sicherheit gestellt Diese Anforderungen sind in der DIN 4420 zusammengefaßt.In the course of increasing occupational safety regulations, work scaffolds are becoming increasingly important. In addition to quick assembly, high demands are placed on safety when it comes to scaffolds. These requirements are summarized in DIN 4420.
Be> Arbeitsgerusten wird zwischen zwei Gerüsttypen den sogenannten Rahmengerüsten und den sogenannten Modulgerüsten, unterschieden KU/\YTX/Plettac/ 1/96 1 Bei Arbeitsgerusten wird zwischen zwei Gerusttypen, den sogenannten Rahmengerusten und den sogenannten Modulgerusten, unterschieden Die Rahmengeruste bestehen insbesondere aus vertikalen Rohrrahmenelementeπ die mit direkt aussteifenden Belagen sowie Gelander- und Vertikaldiagonalstreben verbunden sindWorking scaffolding is differentiated between two types of scaffolding, the so-called frame scaffolding and the so-called modular scaffolding, KU / \ YTX / Plettac / 1/96 1 In the case of working scaffolding, a distinction is made between two types of scaffolding, the so-called frame scaffolds and the so-called modular scaffolds. The frame scaffolds consist in particular of vertical tubular frame elements which are connected to directly stiffening coverings and railing and vertical diagonal struts
Abweichend davon haben die Modulgeruste als Vertikalstander Einzelrohre, die in regelmäßigen Abstanden Haltevorrichtungen zum Einhangen von Auflageriegeln und Längs- und Diagonalstreben aufweisen Jeweils zwei Stander werden mittels der Auflageriegel paarweise verbunden und jedes Standerpaar in Längsrichtung mittels Langsstreben, einhangbaren Belagen und Diagonalen ausgesteiftDeviating from this, the modular scaffolds as vertical stands have individual tubes that have holding devices at regular intervals for hanging in support bars and longitudinal and diagonal struts

Bei der anderen Befestigungsart verfugt der Auflageπegel über eine vorzugsweise durchgehende Nut, in die an dem Belag befestigte Hacken oder Klauen eingehängt werden, um eine Verbindung zwischen Belag und Auflageπegel herzustellenIn the other type of attachment, the support surface has a preferably continuous groove into which hooks or claws attached to the cover are hung in order to establish a connection between the cover and the support surface
Neben der Sicherheit spielt die Kombinierbarkeit beider Gerusttypen untereinander ein bedeutende Rolle, weil dadurch flexibler disponiert und komplizierte Bauwerke einfacher eingerüstet werden können Dabei ist es vorteilhaft, wenn der Achsabstand des Standerpaars eines Modulgerustes mit dem festliegenden Achsabstand der vertikalen Rohrrahmenelemente der Rahmengeruste übereinstimmtIn addition to safety, the combinability of the two types of scaffolding plays an important role, because it makes it more flexible to plan and complicated structures can be installed more easily.It is advantageous if the center distance of the pair of pillars of a modular scaffolding matches the fixed center distance of the vertical tubular frame elements of the frame scaffolding
Diese Kombinierbarkeit war bisher nur bei Gerüsten möglich, bei denen die Belage über Haken oder Klauen verfugen, die in die Nut eines Auflageriegels eingehängt werden, da bei diesen Gerüsten der Achsabstand der Standerpaare des Modulgerustes identisch sein kann mit dem Achsabstand der vertikalen Rohrrahmenlemente des RahmengerustesThis combinability was previously only possible with scaffolds in which the coverings have hooks or claws that are hooked into the groove of a support bar, because with these scaffolds the center distance of the pairs of columns of the Modular framework can be identical to the center distance of the vertical tubular frame elements of the framework
Modulgeruste hingegen, bei denen die Belage Locher oder Ösen aufweisen, die zu ihrem Einhangen in das Gerüst über Bolzen an dem Auflageπegel geschoben werden, konnten bisher nur mit großem Aufwand mit Rahmengerusten kombiniert werden Insbesondere deshalb, weil der Auflageriegel und damit der Achsabstand des Standerpaars des Modulgerustes großer sein mußte als der Achsabstaπd eines entsprechenden Rahmengerustes Dadurch entstand als zusatzlicher Nachteil zwischen Standerelement und der Belagaußenkante auch noch ein relativ großer Spalt mit einem entsprechenden SicherheitsrisikoModular scaffolds, on the other hand, in which the coverings have holes or eyelets that are pushed into the scaffolding by means of bolts on the support frame, could previously only be combined with frame scaffolds with great effort, in particular because the support bar and thus the center distance of the pair of stands The module frame had to be larger than the axis spacing of a corresponding frame frame. This created an additional disadvantage between the stand element and the outer edge of the covering and a relatively large gap with a corresponding safety risk
Der vorliegenden Erfindung hegt deshalb die Aufgabe zugrunde, für ein Modulgerustsystem bei dem die Belage Locher oder Ösen aufweisen, die zum Einhangen der Belage in das Gerüst über Bolzen an dem Auflageπegel geschoben werden, die Verbindungsvorrichtung des Auflageπegels bzw den Auflageπegel so zu verändern, daß ein nahezu identischer Achsabstand der Standerpaare des Modulgerustes zu dem Achsabstand der vertikalen Rohrrahmenlemente des Rahmengerustes erzielt werden kann und daß die Belage möglichst nahe an die Standerelemente herangelegt werden könnenThe present invention is therefore based on the object, for a modular scaffolding system in which the coverings have holes or eyelets which are pushed over the bolts in order to hang the coverings into the framework, to change the connecting device of the support surface or the support surface so that a almost identical center distance of the pairs of stands of the modular framework to the center distance of the vertical tubular frame elements of the framework can be achieved and that the coverings can be placed as close as possible to the stand elements
