Description

Die Erfindung betrifft eine Anordnung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an arrangement according to the preamble of claim 1.

Aus der EP 0 351 703 B1 ist eine Anordnung bekannt, welche ein erstes Gerüstbauteil und ein zweites Gerüstbauteil umfasst, wobei das erste Gerüstbauteil einen Träger, einen Anschlusskopf und einen Keil umfasst, wobei der Anschlusskopf einen oberen Kopfteil mit einem oberen Keilkanal und einen unteren Kopfteil mit einem unteren Keilkanal umfasst, wobei zwischen dem oberen Kopfteil und dem unteren Kopfteil ein in Richtung einer Längsachse des Trägers verlaufender Aufnahmeschlitz ausgebildet ist, wobei die Keilkanäle senkrecht zu der Längsachse des Trägers in Richtung einer Hochachse verlaufen und jeweils in den Aufnahmeschlitz münden, wobei das zweite Gerüstbauteil ein Gerüstrohr und einen Vorsprung umfasst, wobei der Vorsprung sich quer zu einer Längsachse des Gerüstrohrs von dieser weg erstreckt und wenigstens eine Öffnung aufweist, wobei bei verbundenen Gerüstbauteilen der Anschlusskopf unter Ausbildung einer lösbaren Verbindung auf den Vorsprung aufgesteckt ist und der Keil durch den oberen Keilkanal, durch eine der Öffnungen des Vorsprungs und durch den unteren Keilkanal gesteckt ist, wobei der Aufnahmeschlitz eine durch einen oberen Kopfteil ausgebildete Decke, einen durch einen unteren Kopfteil ausgebildeten Boden und eine durch das Kopfteil zwischen dem oberen Kopfteil und dem unteren Kopfteil ausgebildete Wand aufweist und wobei sich der Aufnahmeschlitz zu einer von dem Träger abgewandten Stirnseite des Anschlusskopfes öffnet.From the EP 0 351 703 B1 an arrangement is known which comprises a first scaffolding component and a second scaffolding component, the first scaffolding component comprising a beam, a connection head and a wedge, the connection head comprising an upper head part with an upper wedge channel and a lower head part with a lower wedge channel, wherein A receiving slot running in the direction of a longitudinal axis of the carrier is formed between the upper head part and the lower head part, with the wedge channels running perpendicular to the longitudinal axis of the carrier in the direction of a vertical axis and each opening into the receiving slot, with the second scaffolding component having a scaffolding tube and a projection comprises, wherein the projection extends transversely to a longitudinal axis of the scaffolding tube away from it and has at least one opening, wherein when scaffolding components are connected, the connection head is pushed onto the projection to form a detachable connection and the wedge through the upper wedge channel, through one of the openings of the boss and inserted through the lower wedge channel, the receiving slot having a ceiling formed by a top header, a floor formed by a bottom header, and a wall formed by the header between the top header and the bottom header, and wherein the receiving slot narrows toward an end face of the connection head facing away from the carrier.

JP 2000 179150 A offenbart eine Anordnung, welche ein erstes Gerüstbauteil und ein zweites Gerüstbauteil umfasst. JP 2000 179150A discloses an assembly comprising a first framework member and a second framework member.

Es ist Aufgabe der Erfindung, eine Anordnung vorzuschlagen, bei welcher der Vorsprung mit geringem Spiel in dem Aufnahmeschlitz aufgenommen ist und die Kraftübertragung von dem ersten Gerüstbauteil auf das zweite Gerüstbauteil optimiert ist.It is the object of the invention to propose an arrangement in which the projection with little play in the receiving slot is included and the power transmission is optimized from the first scaffolding component to the second scaffolding component.

Diese Aufgabe wird ausgehend von den Merkmalen des Oberbegriffs des Anspruchs 1 durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. In den Unteransprüchen sind vorteilhafte und zweckmäßige Weiterbildungen angegeben.Starting from the features of the preamble of claim 1, this object is achieved by the characterizing features of claim 1. Advantageous and expedient developments are specified in the dependent claims.

Die erfindungsgemäße Anordnung umfasst ein erstes Gerüstbauteil und ein zweites Gerüstbauteil, gemäß Anspruch 1.The arrangement according to the invention comprises a first scaffolding component and a second scaffolding component, according to claim 1.

Hierdurch wird eine gewünschte Zentrierwirkung erreicht, so dass das Spiel zwischen den Gerüstbauteilen im zusammengebauten Zustand gering ist. Weiterhin wird hierdurch erreicht, dass das obere Kopfteil vollflächig auf dem Vorsprung aufliegt, so dass der Randbereich des Vorsprungs weniger belastet ist und eine großflächige Kraftübertragung von dem ersten Gerüstbauteil auf das zweite Gerüstbauteil gewährleistet ist. Durch eine derartige Abstimmung des Aufnahmeschlitzes und der Lochscheibe wird trotz eines geringen Spiels ein leichtgängiges Aufschieben des ersten Gerüstbauteils auf das zweite Gerüstbauteil und ein leichtgängiges Trennen des ersten Gerüstbauteils von dem zweiten Gerüstbauteil erreicht.As a result, a desired centering effect is achieved, so that the play between the scaffolding components in the assembled state is small. Furthermore, this ensures that the upper head part rests over the entire surface on the projection, so that the edge area of the projection is less stressed and a large-area transmission of force from the first scaffolding component to the second scaffolding component is ensured. By matching the receiving slot and the perforated disk in this way, the first framework component can be pushed smoothly onto the second framework component and the first framework component can be easily separated from the second framework component, despite a small amount of play.

Insbesondere die Ausbildung der am oberen Kopfteil ausgebildete Decke, und des am unteren Kopfteil ausgebildeten Bodens als eine ausgedehnte Fläche bietet gegenüber z.B. einem abgekanteten oder stranggepressten Profil eine erheblich höhere Stabilität und Flächenlast und erhöht damit die Belastbarkeit des betreffenden Anschlusskopfes. Überdies ist ein Verklemmen von in Hohlräumen eingeschlossenen Fremdkörpern, z.B. Kieselsteine oder Betonresten stark vermindert.In particular, the formation of the ceiling formed on the upper head part and the base formed on the lower head part as an extended surface offers a significantly higher stability and surface load compared to e.g. a folded or extruded profile and thus increases the resilience of the relevant connection head. In addition, jamming of foreign bodies enclosed in cavities, e.g. pebbles or remains of concrete, is greatly reduced.

Ein Anstieg des Bodens ist stufenförmig ausgebildet und umfasst wenigstens eine Stufe mit einer schrägstehenden Stirnfläche. Hierdurch ist sichergestellt, dass die Stufe beim Aufschieben des ersten Gerüstbauteils auf den Vorsprung des zweiten Gerüstbauteils keinen Anschlag bildet, welcher die erforderliche Aufschiebekraft sprunghaft vergrößert.An increase in the floor is stepped and comprises at least one step with a sloping end face. This is ensures that the stage does not form a stop when the first scaffolding component is pushed onto the projection of the second scaffolding component, which suddenly increases the required push-on force.

Weitere Einzelheiten der Erfindung werden in der Zeichnung anhand von schematisch dargestellten Ausführungsbeispielen beschrieben.Further details of the invention are described in the drawing with reference to exemplary embodiments shown schematically.

In der Figur 1 ist eine erfindungsgemäße Anordnung 1 in Seitenansicht gezeigt. Diese Anordnung 1 ist in der Figur 2 nochmals in Schnittansicht dargestellt. Die Anordnung 1 umfasst ein erstes Gerüstbauteil 101 und ein zweites Gerüstbauteil 201.In the figure 1 an arrangement 1 according to the invention is shown in a side view. This arrangement 1 is in the figure 2 shown again in a sectional view. The arrangement 1 comprises a first framework component 101 and a second framework component 201.

Das erste Gerüstbauteil 101 umfasst einen Träger 102, einen Anschlusskopf 103 und einen Keil 104. Weiterhin umfasst das erste Gerüstbauteil 101 an dem Träger 102 einen weiteren, nicht dargestellten Anschlusskopf und einen weiteren, nicht dargestellten Keil, wobei der weitere Anschlusskopf dem Anschlusskopf 103 gegenüber liegend angeordnet ist. Der Anschlusskopf 103 umfasst einen oberen Kopfteil 105 mit einem oberen Keilkanal 106 und einen unteren Kopfteil 107 mit einem unteren Keilkanal 108. Zwischen dem oberen Kopfteil 105 und dem unteren Kopfteil 107 ist ein in Richtung einer Längsachse L102 des Trägers 102 verlaufender Aufnahmeschlitz 109 ausgebildet.The first scaffolding component 101 comprises a support 102, a connection head 103 and a wedge 104. Furthermore, the first scaffolding component 101 on the support 102 comprises a further connection head (not shown) and a further wedge (not shown), the further connection head lying opposite the connection head 103 is arranged. The connection head 103 includes an upper head portion 105 with a upper wedge channel 106 and a lower head part 107 with a lower wedge channel 108. Between the upper head part 105 and the lower head part 107 there is a receiving slot 109 running in the direction of a longitudinal axis L102 of the carrier 102.

Die Keilkanäle 106, 108 verlaufen senkrecht zu der Längsachse L102 des Trägers 102 in Richtung einer Hochachse H103 des Anschlusskopfes 103 und münden jeweils in den Aufnahmeschlitz 109.The wedge channels 106, 108 run perpendicular to the longitudinal axis L102 of the carrier 102 in the direction of a vertical axis H103 of the connection head 103 and each open into the receiving slot 109.

Das zweite Gerüstbauteil 201, welches als Gerüststiel ausgebildet ist, umfasst ein Gerüstrohr 202 und einen Vorsprung 203, welcher durch eine Lochscheibe 204 gebildet ist. Die Lochscheibe 204 ist mit dem Gerüstrohr 202 verschweißt. Der Vorsprung 203 erstreckt sich quer zu einer Längsachse L202 des Gerüstrohrs 202 von dieser weg und umfasst acht Öffnungen, von welchen eine linke Öffnung 205a und eine rechte Öffnung 205b in der Figur 1 bezeichnet sind. Bei verbundenen Gerüstbauteilen 101, 201 ist der Anschlusskopf 103 zur Ausbildung einer lösbaren Verbindung auf den Vorsprung 203 aufgesteckt und der Keil 104 ist mit einem Mittelbereich 104a zur Verbindung der beiden Gerüstbauteile 101, 201 durch den oberen Keilkanal 106, durch die linke Öffnung 205a des Vorsprungs 203 und durch den unteren Keilkanal 108 gesteckt. Der Aufnahmeschlitz 109 ist durch eine durch den oberen Kopfteil 105 ausgebildete Decke 110, durch einen durch den unteren Kopfteil 107 ausgebildeten Boden 111 und durch eine von dem Anschlusskopf 103 zwischen dem oberen Kopfteil 105 und dem unteren Kopfteil 107 ausgebildete Wand 112 begrenzt. Der Aufnahmeschlitz 109 ist in der Figur 3 nochmals als Detailansicht der Figur 1 gezeigt. Der Aufnahmeschlitz 109 öffnet sich zu einer von dem Träger 102 abgewandten Stirnseite 113 des Anschlusskopfes 103. Hierbei ist die Decke 110 des Aufnahmeschlitzes 109 als plane Auflagefläche 114 ausgebildet und hierbei steigt der Boden 111 zu der Wand 112 hin an. Der Anstieg des Bodens 111 ist stufenförmig ausgebildet und dieser geht mit einer Stufe 115, welche eine schräg stehende Stirnfläche 116 umfasst, von einer unteren Teilfläche 111a des Bodens 111 in eine obere Teilfläche 111b des Bodens 111 über.The second scaffolding component 201, which is designed as a scaffolding post, comprises a scaffolding tube 202 and a projection 203, which is formed by a perforated disk 204. The perforated disk 204 is welded to the scaffold tube 202 . The projection 203 extends transversely to a longitudinal axis L202 of the scaffold tube 202 away from this and includes eight openings, of which a left opening 205a and a right opening 205b in the figure 1 are designated. When the scaffolding components 101, 201 are connected, the connecting head 103 is placed on the projection 203 to form a detachable connection and the wedge 104 is provided with a central area 104a for connecting the two scaffolding components 101, 201 through the upper wedge channel 106, through the left-hand opening 205a of the projection 203 and inserted through the lower wedge channel 108. The receiving slot 109 is delimited by a ceiling 110 formed by the upper head part 105, by a floor 111 formed by the lower head part 107 and by a wall 112 formed by the connection head 103 between the upper head part 105 and the lower head part 107. The receiving slot 109 is in the figure 3 again as a detailed view of the figure 1 shown. The receiving slot 109 opens to an end face 113 of the connection head 103 that faces away from the carrier 102 and here the floor 111 rises towards the wall 112 . The rise of the base 111 is step-shaped and this transitions from a lower partial surface 111a of the base 111 into an upper partial surface 111b of the base 111 with a step 115 which comprises an inclined end face 116 .

Entsprechend nimmt eine Höhe des Aufnahmeschlitzes 106, in Richtung des Trägers 102 betrachtet, von einer ersten Höhe H111a im Bereich der unteren Teilfläche 111a auf eine zweite Höhe h111b im Bereich der oberen Teilfläche 111b ab. In Bezug auf eine Dicke D204 der den Vorsprung 203 bildenden Lochscheibe 204 beträgt die zweite Höhe h111b maximal das 1,3-fache der Dicke D204 und beträgt die erste Höhe h111a maximal das 1,4-fache der Dicke D204. Vorzugsweise ist eine Dicke D204 von 9 mm, eine erste Höhe h111a von 12 mm und eine zweite Höhe h111b von 11 mm vorgesehen. Der Keil 104 ist in den Figuren jeweils in seiner Klemmstellung K104 gezeigt, in welcher dieser den Keilkanal 106 und den Keilkanal 108 durchläuft und zwischen den Keilkanälen 106, 108 durch die erste Öffnung 205a des als Lochscheibe 204 ausgebildeten Vorsprungs 203 geführt ist und maximal in die Öffnung 205a eintaucht, so dass das erste Gerüstteil 101 mit der Stirnseite 113 seines Anschlusskopfes 103 an eine Mantelfläche 202a des Gerüstrohrs 202 herangezogen wird. Durch ein Anheben des Keils 104, welches derart erfolgt, dass ein unteres Ende 104c des Keils in dem Anschlusskopf 103 aus dem unteren Keilkanal 108 und der ersten Öffnung 205a nach oben herausgezogen wird, erfolgt eine Trennung des ersten Gerüstteils 101 von dem zweiten Gerüstteil 201. Hierbei ist der Keil 103 unverlierbar, verschiebbar und verschwenkbar an dem Anschlusskopf 103 des ersten Gerüstteils 101 gehalten.Correspondingly, a height of the receiving slot 106, viewed in the direction of the carrier 102, decreases from a first height H111a in the region of the lower partial surface 111a to a second height h111b in the region of the upper partial surface 111b. In relation to a thickness D204 of the perforated disk 204 forming the projection 203, the second height h111b is at most 1.3 times the thickness D204 and the first height h111a is at most 1.4 times the thickness D204. A thickness D204 of 9 mm, a first height h111a of 12 mm and a second height h111b of 11 mm are preferably provided. The figures show the wedge 104 in its clamping position K104, in which it runs through the wedge channel 106 and the wedge channel 108 and is guided between the wedge channels 106, 108 through the first opening 205a of the projection 203 designed as a perforated disk 204 and at most into the Opening 205a is immersed, so that the first scaffolding part 101 is used with the end face 113 of its connection head 103 against a lateral surface 202a of the scaffolding tube 202. By raising the wedge 104, which takes place in such a way that a lower end 104c of the wedge in the connection head 103 is pulled upwards out of the lower wedge channel 108 and the first opening 205a, the first frame part 101 is separated from the second frame part 201. In this case, the wedge 103 is held captive, displaceable and pivotable on the connection head 103 of the first frame part 101 .

Insbesondere die Ausbildung der am oberen Kopfteil ausgebildete Decke 110, und des am unteren Kopfteil ausgebildeten Bodens 111 als je eine ausgedehnte Fläche bietet gegenüber z.B. einem abgekanteten oder stranggepressten Profil eine erheblich höhere Stabilität und Flächenlast und erhöht damit die Belastbarkeit des betreffenden Anschlusskopfes.In particular, the formation of the top 110 formed on the upper head part and the base 111 formed on the lower head part than an extended surface offers a significantly higher stability and surface load compared to eg a folded or extruded profile and thus increases the load capacity of the connection head in question.

Dabei sind die Flächen in ihrer Ausdehnung insbesondere über ein vielfaches gegenüber der darin liegenden Querschnittsfläche der Keilkanäle (106, 108) ausgebildet. Diese maximierte Auflagefläche erhöht die Belastbarkeit der Aufnahme des Anschlusskopfes.In this case, the areas are formed in their extent in particular over a multiple of the cross-sectional area of the wedge channels (106, 108) located therein. This maximized contact surface increases the resilience of the connection head receptacle.

Gegenüber einem Anschlusskopf z.B. aus abgekanteten Flachelementen besteht z.B. der Vorteil, dass neben der verbesserten Stabilität und Flächenlast auch keine Fremdkörper, z.B. Kieselsteine oder Betonreste oder dergleichen in die Zwischenräumen gelangen können, welche zu einem verklemmen oder verspannen des Anschlusskopfes mit der aufzunehmenden Lochscheibe führt.Compared to a connection head made of folded flat elements, for example, there is the advantage that, in addition to the improved stability and distributed load, no foreign bodies, e.g. pebbles or concrete residues or the like can get into the gaps, which could lead to the connection head jamming or twisting with the perforated disc to be accommodated.

Claims (2)

  1. Arrangement (1) comprising a first scaffold component (101) and a second scaffold component (201),
    - wherein the first scaffold component (101) comprises a carrier (102), a connection head (103) and a wedge (104),
    - wherein the connection head (103) comprises an upper head part (105) with an upper wedge channel (106) and a lower head part (107) with a lower wedge channel (108),
    - wherein a receiving slot (109) extending in the direction of a longitudinal axis (L102) of the carrier (102) is formed between the upper head part (106) and the lower head part (108),
    - wherein the wedge channels (106, 108) extend perpendicularly to the longitudinal axis (L102) of the carrier (102) in the direction of a vertical axis (H103) and in each case open out into the receiving slot (109),
    - wherein the second scaffold component (201) comprises a scaffolding tube (202) and a projection (203), wherein the projection (203) extends transversely to a longitudinal axis (L202) of the scaffolding tube (202) away therefrom and has at least one opening (205a, 205b),
    - wherein, with the scaffold components (101, 201) connected, the connection head (103) is plugged onto the projection (203) such that a releasable connection is formed and the wedge (104) is plugged through the upper wedge channel (106), through one of the openings (205a, 205b) of the projection (203) and through the lower wedge channel (108),
    - wherein the receiving slot (109) has a top (110) formed by the upper head part (105), a base (111) formed by the lower head part (107) and a wall (112) formed by the connection head (103) between the upper head part (105) and the lower head part (107), and
    - wherein the receiving slot (109) opens towards an end face (113) of the connection head (103) that faces away from the carrier (102),
    - wherein the top (110) is in the form of a flat bearing surface (114),
    - and wherein the base (111) rises towards the wall (112),
    characterized
    in that a rise of the base (111) is formed in a stepped manner, and, by way of a step (115) which comprises an inclined end face (116), this transitions from a lower part-surface (111a) of the base (111) into an upper part-surface (111b) of the base (111),
    - wherein, correspondingly, a height of the receiving slot (106), as seen in the direction of the carrier (102), decreases from a first height (H111a) in the region of the lower part-surface (111a) to a second height (h111b) in the region of the upper part-surface (111b),
    - wherein, in relation to a thickness (D204) of a perforated disc (204) which forms the projection (203), the second height (h111b) is at most 1.3 times the thickness (D204) and the first height (h111a) is at most 1.4 times the thickness (D204).
  2. Arrangement according to one of the preceding claims, characterized in that the top (110) formed on the upper head part and the base (111) formed on the lower head part are formed as an extensive surface over the entire bearing region of the receiving slot (109), in particular over an extent a number of times the area of the cross-sectional surface, situated therein, of the wedge channels (106, 108).
