Definitions

  • the invention relates to a method for producing a scaffold plank for a scaffolding, in which a substantially smooth continuous, the upper side of the scaffold plank forming upper sheet metal profile with a corrugated, in cross-section trapezoidal troughs and valleys having the underside of the scaffold plank lower sheet profile connects.
  • Such a scaffold plank is known for example from FR-A 24 57 946. There, however, it is the case that the scaffold plank consists of an upper continuous plate and a lower continuous plate, with a trapezoidal corrugated plate being provided as the core between the two plates.
  • the scaffolding planks mentioned at the outset already have the advantage that they are relatively insensitive to the effects of the weather.
  • the use of steel sheets increases the weight of the scaffolding planks if you want to maintain their rigidity.
  • the object of the present invention is therefore to improve a scaffold plank of the type mentioned at the outset so that its stability is increased while the weight is reduced.
  • the sheet thickness of the sheet profiles can be kept very low. A certain minimum thickness will only have to be provided for the upper sheet metal profile in order to avoid damage to the sheet metal profile from falling tools.
  • the essentially point-by-point or section-wise linear connection of the upper and lower sheet metal profiles causes the foam filled into the cavity to deform at least slightly during its expansion and to brace it against one another. Even if the connection of the wave crests of the lower sheet profile to the upper sheet profile should still permit any movements, these movements are prevented by the foam bracing the two sheet profiles against one another.
  • the scaffold plank is completely rigid for the person entering it, evenly over the entire surface of the scaffold plank.
  • a foamed scaffold plank is already known from GB-20 58 188; there, however, the top and bottom of the scaffold plank consist of a glass fiber reinforced plastic, the cavities of which are only filled. Bracing the top of the scaffold plank against the underside is neither provided nor desirable since the glass fiber reinforced Plastic would be damaged in this way.
  • the foam can be a polyurethane foam.
  • the cavity enclosed by the upper and lower sheet metal profiles can be realized in a simple manner in that the upper sheet metal profile is bent downward at its longitudinal edges and engages around the longitudinal edges of the lower sheet metal profile.
  • This has the advantage that the long edges do not have to be connected to one another in a special way. Rather, the foam expanding in the cavity presses the encompassing longitudinal edges into one another.
  • the longitudinal edges of the lower sheet metal profile are formed by corrugated valleys spaced apart from the upper sheet metal profile, and on the other hand, in the corrugated valleys, adjacent to the longitudinal edges, longitudinally extending, upwardly directed beads are formed in which engages a hook tab of the upper plate from below. This creates a positive locking of the long edges of the upper and lower sheet when foaming the screed.
  • the longitudinal edges are sealed due to the inclined surfaces pressing against each other, so that no foam can escape to the outside.
  • the lower sheet profile has a sinusoidal cross section
  • the selected lower sheet profile has trapezoidal wave troughs and peaks in cross section.
  • the total volume of the cavity to be filled with foam can be kept relatively low without the stability of the scaffold board suffering as a result.
  • the upper profile sheet forming the top of the screed has a tread with embossments.
  • the indentations rise to the top of the scaffold board '.
  • the impressions can preferably be longer than wide and arranged in a herringbone-like pattern.
  • the herringbone pattern oblique to the longitudinal direction of the scaffold board is oriented so that different longitudinal directions are arranged at the longitudinal edges of the tread impressions'. This has the advantage that there is no continuous line in the direction toward the longitudinal direction of the screed, which would favor buckling of the scaffold plank in the event of a point load in the center of the scaffold plank.
  • the thickness of the lower sheet profile is less than that of the upper sheet profile. Since the upper sheet metal profile hardly has a supporting function, the thickness of the upper profile sheet is determined essentially on the basis of the puncture resistance required in order to prevent damage from falling tools or the like. Since the underside of the scaffold plank is not exposed to such stresses, the sheet thickness can be correspondingly lower without the static properties of the scaffold plank suffering as a result.

Abstract

PCT No. PCT/EP91/01257 Sec. 371 Date Jan. 6, 1993 Sec. 102(e) Date Jan. 6, 1993 PCT Filed Jul. 4, 1991 PCT Pub. No. WO92/01131 PCT Pub. Date Jan. 23, 1992.To improve the stability of a scaffold board consisting of an upper sheet section and a lower waved sheet section and to reduce its weight at the same time, the lower sheet section is connected with its wave tops substantially pointwise to the upper sheet section. The resultant cavities are foamed with an expanding and curing foam, with the expanding foam squeezing the upper and lower sheet sections apart.

Description

Gerüstbohle und Verfahren zu deren Herstellung Scaffolding screed and process for its manufacture
Beschreibungdescription
Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer Gerüstbohle für ein Baugerüst, bei dem man ein im wesentlichen glatt durchgehendes, die Oberseite der Gerüstbohle bildendes oberes Blechprofil mit einem gewellten, im Querschnitt trapezförmige Wellentäler und -berge aufweisenden, die Unterseite- der Gerüstbohle bildenden unteren Blechprofil verbindet.The invention relates to a method for producing a scaffold plank for a scaffolding, in which a substantially smooth continuous, the upper side of the scaffold plank forming upper sheet metal profile with a corrugated, in cross-section trapezoidal troughs and valleys having the underside of the scaffold plank lower sheet profile connects.
Eine solche Gerüstbohle ist beispielsweise aus der FR-A 24 57 946 bekannt. Dort ist es allerdings so, daß die Gerüstbohle aus einer oberen durchgehenden Platte und einer unteren durchgehenden Platte besteht, wobei als Kern zwischen den beiden Platten ein trapezförmig gewelltes Blech vorgesehen ist.Such a scaffold plank is known for example from FR-A 24 57 946. There, however, it is the case that the scaffold plank consists of an upper continuous plate and a lower continuous plate, with a trapezoidal corrugated plate being provided as the core between the two plates.
Gegenüber herkömmlichen Gerüstbohlen aus dicken Holzbrettern haben die eingangs erwähnten Gerüstbohlen bereits den Vorteil, daß sie gegenüber Witterungseinflüssen verhältnismäßig unempfindlich sind. Allerdings erhöht die Verwendung von Stahlblechen das Gewicht der Gerüstbohlen, wenn man eine ausreichende Steifigkeit derselben erhalten möchte.Compared to conventional scaffolding planks made of thick wooden boards, the scaffolding planks mentioned at the outset already have the advantage that they are relatively insensitive to the effects of the weather. However, the use of steel sheets increases the weight of the scaffolding planks if you want to maintain their rigidity.
Aufgabe der vorliegenden Erfindung ist es daher, eine Gerüstbohle der eingangs genannten Art so zu verbessern, daß deren Stabilität bei gleichzeitiger Verringerung des Gewichtes erhöht wird.The object of the present invention is therefore to improve a scaffold plank of the type mentioned at the outset so that its stability is increased while the weight is reduced.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß man das untere Blechprofil an seinen dem oberen Blechprofil zugewandten Wellenbergen im wesentlichen punktweise mit dem oberen Blechprofil verbindet und anschließend den zwischen dem oberen und dem unteren Blechprofil gebildeten Hohlraum mit einem beim Aushärten expandierenden, die Blechprofile gegeneinander verspannenden Schaum ausschäumt.This object is achieved in that the lower sheet profile on the upper sheet profile Connects wave crests essentially point-wise to the upper sheet metal profile and then foams the cavity formed between the upper and lower sheet metal profile with a foam which expands during curing and braces the sheet metal profiles against one another.
Durch diese Verspannung des oberen Blechprofilε gegenüber dem unteren Blechprofil wird die Steifigkeit der Gerüstbohle stark erhöht. In diesem Zusammenhang ist es erwähnenswert, daß aus statischen Gründen die Blechstärke der Blechprofile sehr gering gehalten werden kann. Lediglich bei dem oberen Blechprofil wird man eine gewisse Mindeststärke vorsehen müssen, um eine Beschädigung des Blechprofils durch herabfallendes Werkzeug zu vermeiden. Die im wesentlichen punktweise oder streckenweise linienförmige Verbindung des oberen und des unteren Blechprofils bewirkt, daß der in den Hohlraum eingefüllte Schaum während seiner Expansion zumindest geringfügig deformiert und gegeneinander verspannt. Selbst dann, wenn die Verbindung der Wellenberge des unteren Blechprofils mit dem oberen Blechprofil noch irgendwelche Bewegungen zulassen sollte, werden diese Bewegungen durch den die beiden Blechprofile gegeneinander verspannenden Schaum verhindert. Die Gerustbohle ist für den dieselbe betretende Person vollkommen starr, und zwar gleichmäßig über die gesamte Fläche der Gerüstbohle.This rigidity of the upper sheet profile compared to the lower sheet profile greatly increases the rigidity of the scaffold plank. In this context, it is worth mentioning that, for static reasons, the sheet thickness of the sheet profiles can be kept very low. A certain minimum thickness will only have to be provided for the upper sheet metal profile in order to avoid damage to the sheet metal profile from falling tools. The essentially point-by-point or section-wise linear connection of the upper and lower sheet metal profiles causes the foam filled into the cavity to deform at least slightly during its expansion and to brace it against one another. Even if the connection of the wave crests of the lower sheet profile to the upper sheet profile should still permit any movements, these movements are prevented by the foam bracing the two sheet profiles against one another. The scaffold plank is completely rigid for the person entering it, evenly over the entire surface of the scaffold plank.
Zwar ist aus der GB-20 58 188 bereits eine ausgeschäumte Gerüstbohle bekannt; dort besteht jedoch die Oberseite und die Unterseite der Gerüstbohle aus einem glasfaserverstärkten Kunststoff, dessen Hohlräume lediglich ausgefüllt sind. Eine Verspannung der Oberseite der Gerüstbohle gegenüber der Unterseite ist weder vorgesehen noch erwünscht, da der glasfaserverstärkte Kunststoff auf diese Weise geschädigt würde.A foamed scaffold plank is already known from GB-20 58 188; there, however, the top and bottom of the scaffold plank consist of a glass fiber reinforced plastic, the cavities of which are only filled. Bracing the top of the scaffold plank against the underside is neither provided nor desirable since the glass fiber reinforced Plastic would be damaged in this way.
Gemäß einer bevorzugten Ausführungεform kann der Schaum ein Polyurethanschaum sein.According to a preferred embodiment, the foam can be a polyurethane foam.
Der durch das obere und das untere Blechprofil umschlossene Hohlraum läßt sich auf einfache Weise dadurch verwirklichen, daß das obere Blechprofil an seinen Längskanten nach unten abgebogen ist und die Längskanten des unteren Blechprofils umgreift. Das hat den Vorteil, daß die Langskanten nicht auf besondere Weise miteinander verbunden werden müssen. Vielmehr drückt der im Hohlraum expandierende Schaum die sich umgreifenden Längskanten ineinander. In diesem Zusammenhang ist es besonders günstig, wenn zum einen die Längskanten des unteren Blechprofils durch vom oberen Blechprofil beabstandete Wellentäler gebildet sind, und wenn zum anderen in den Wellentälern, benachbart zu den Längskanten, sich längs erstreckende, nach oben gerichtete Sicken ausgebildet sind, in die eine Hakenlasche des oberen Blechs von unten eingreift. Hierdurch entsteht eine formschlüssige Verriegelung der Langskanten des oberen und des unteren Blechs beim Ausschäumen der Gerustbohle. Gleichzeitig werden die Längskanten wegen der gegeneinander drückenden Schrägflächen abgedichtet, so daß kein Schaum nach außen dringen kann.The cavity enclosed by the upper and lower sheet metal profiles can be realized in a simple manner in that the upper sheet metal profile is bent downward at its longitudinal edges and engages around the longitudinal edges of the lower sheet metal profile. This has the advantage that the long edges do not have to be connected to one another in a special way. Rather, the foam expanding in the cavity presses the encompassing longitudinal edges into one another. In this context, it is particularly advantageous if, on the one hand, the longitudinal edges of the lower sheet metal profile are formed by corrugated valleys spaced apart from the upper sheet metal profile, and on the other hand, in the corrugated valleys, adjacent to the longitudinal edges, longitudinally extending, upwardly directed beads are formed in which engages a hook tab of the upper plate from below. This creates a positive locking of the long edges of the upper and lower sheet when foaming the screed. At the same time, the longitudinal edges are sealed due to the inclined surfaces pressing against each other, so that no foam can escape to the outside.
Obgleich es auch denkbar wäre, daß das untere Blechprofil im Querschnitt einen sinusförmigen Verlauf aufweist, wird bevorzugt, daß das gewählte untere Blechprofil im Querschnitt trapezförmige Wellentäler und -berge aufweist. Hierdurch läßt sich das Gesamtvolumen des mit Schaum auszufüllenden Hohlraumes verhältnismäßig gering halten, ohne daß die Stabilität der Gerustbohle darunter leidet. Zur Erhöhung der Rutschsicherheit ist es günstig, wenn das die Oberseite der Bohle bildende obere Profilblech eine Lauffläche mit Einprägungen aufweist. Hierbei wird bevorzugt, wenn sich die Einprägungen zur Oberseite der Gerüstbohle' erheben. Die Einprägungen können in bevorzugter Weise länger als breit sein und in einem fischgrätähnlichen Muster angeordnet sein. Hierbei wird bevorzugt, wenn das Fischgrätmuster schräg zur Längsrichtung der Gerüstbohle orientiert ist, so daß an den Längsrändern der Lauffläche Einprägungen unterschiedlicher Längsrichtungen'angeordnet sind. Das hat den Vorteil, daß sich in Richtung guer zur Längsrichtung der Laufbohle keine durchgehende Linie erstreckt, die ein Knicken der Gerüstbohle bei einer punktförmigen Belastung in der Mitte der Gerüstbohle begünstigen würde.Although it would also be conceivable that the lower sheet profile has a sinusoidal cross section, it is preferred that the selected lower sheet profile has trapezoidal wave troughs and peaks in cross section. As a result, the total volume of the cavity to be filled with foam can be kept relatively low without the stability of the scaffold board suffering as a result. To increase the slip resistance, it is favorable if the upper profile sheet forming the top of the screed has a tread with embossments. Here, it is preferable that the indentations rise to the top of the scaffold board '. The impressions can preferably be longer than wide and arranged in a herringbone-like pattern. Here, it is preferred if the herringbone pattern oblique to the longitudinal direction of the scaffold board is oriented so that different longitudinal directions are arranged at the longitudinal edges of the tread impressions'. This has the advantage that there is no continuous line in the direction toward the longitudinal direction of the screed, which would favor buckling of the scaffold plank in the event of a point load in the center of the scaffold plank.
Um auf einfache Weise das Gewicht der Gerüstbohle noch weiter zu senken ist es günstig, wenn die Stärke des unteren Blechprofils geringer ist als die des oberen Blechprofils. Da das obere Blechprofil kaum eine tragende Funktion hat, bestimmt sich die Stärke des oberen Profilblechs im wesentlichen aufgrund der geforderten Durchstoßfestigkeit, um Beschädigungen durch herabfallende Werkzeuge oder dergleichen zu verhindern. Da die Unterseite der Gerustbohle solchen Beanspruchungen nicht ausgesetzt ist, kann die Blechstärke entsprechend geringer sein, ohne daß darunter die statischen Eigenschaften der Gerüstbohle leiden.In order to further reduce the weight of the scaffold plank in a simple manner, it is advantageous if the thickness of the lower sheet profile is less than that of the upper sheet profile. Since the upper sheet metal profile hardly has a supporting function, the thickness of the upper profile sheet is determined essentially on the basis of the puncture resistance required in order to prevent damage from falling tools or the like. Since the underside of the scaffold plank is not exposed to such stresses, the sheet thickness can be correspondingly lower without the static properties of the scaffold plank suffering as a result.
Im folgenden wird ein Ausführungεbeispiel einer erfindungsgemäßen Gerüstbohle anhand einer Zeichnung näher erläutert. Es zeigen:An exemplary embodiment of a scaffolding screed according to the invention is explained in more detail below with reference to a drawing. Show it:

Fig. 5 in einer ähnlichen Ansicht wie Fig. 1 eine weitere Variante einer Gerüstbohle.Fig. 5 in a view similar to Fig. 1, a further variant of a scaffold plank.
Die in der Zeichnung dargestellte Gerustbohle 1 besteht, wie insbesondere aus der vergrößerten Querschnittsdarstellung in Fig. 3 ersichtlich ist, aus einem die Oberseite 2 bildenden oberen Blechprofil 3 und einem gewählten unteren Blechprofil 4. Die durch die im Querschnitt des unteren Blechprofils 4 trapezförmigen Wellen erreichten Profilierungen erstrecken sich in Längsrichtung der Gerustbohle 1. Die dem oberen Blechprofil 3 zugewandten Kellenberge 5 sind an den Stellen 6 mit dem oberen Blechprofil 3 im Fügeverfahren miteinander verbunden, d.h. also ohne Einsatz von Fremdmaterial verstanzt bzw. vernietet.The scaffold plank 1 shown in the drawing consists, as can be seen in particular from the enlarged cross-sectional view in FIG. 3, of an upper sheet metal profile 3 forming the upper side 2 and a selected lower sheet metal profile 4. The waves achieved by the trapezoidal waves in the cross section of the lower sheet metal profile 4 Profiles extend in the longitudinal direction of the screed 1. The trowel peaks 5 facing the upper sheet profile 3 are connected to one another at points 6 with the upper sheet profile 3 in the joining process, ie punched or riveted without the use of foreign material.
An den Längsrändern 7 der Gerustbohle sind das obere und das untere Blechprofil 3 und 4 miteinander verbunden. Das untere Blechprofil 4 endet hierzu im Bereich der Längsränder mit einem von dem oberen Blechprofil 3 beabstandeten Wellental 8, das in seiner Mitte endet. Von dort aus erstreckt sich das untere Blechprofil 4 noch in einem vertikalen Abschnitt 9 nach oben und endet dann in einem horizontalen Schenkel 10.The upper and lower sheet metal profiles 3 and 4 are connected to one another at the longitudinal edges 7 of the scaffold plank. For this purpose, the lower sheet profile 4 ends in the area of the longitudinal edges with a wave trough 8 spaced from the upper sheet profile 3, which ends in the middle. From there, the lower sheet metal profile 4 still extends upwards in a vertical section 9 and then ends in a horizontal leg 10.
Das obere Blechprofil 3 umgreift von außen den horizontalen Schenkel 10, den Abschnitt 9 und greift mit einer frei endenden Hakenlasche 11 in eine längs verlaufende, nach oben gerichtete Sicke 17 des unteren Wellentals 8 des unteren Blechprofils 4 ein.The upper sheet profile 3 encompasses the horizontal leg 10, the section 9 from the outside and engages with a freely ending hook tab 11 into a longitudinal, upward-facing bead 17 of the lower wave valley 8 of the lower sheet metal profile 4.
Die sich durch die Verbindung des oberen Blechprofils 3 mit dem unteren Blechprofil 4 ergebenden Kammern 12 und 12' des von den Blechprofilen 3 und 4 eingeschlossenen Hohlraumes werden mit einem Polyurethanschaum ausgeschäumt, der beim Aushärten noch expandiert.The chambers 12 and 12 'of the cavity enclosed by the sheet metal profiles 3 and 4 resulting from the connection of the upper sheet metal profile 3 to the lower sheet metal profile 4 are foamed with a polyurethane foam which expands during curing.
Wie aus Fig. 1 und 2 ersichtlich ist, sind an den stirnseitigen Enden der Gerustbohle 1 Querprofile 13 angenietet, an denen die Anschlußhaken 14 zum Einhängen in das Gerüst befestigt sind.As can be seen from FIGS. 1 and 2, 1 cross profiles 13 are riveted to the front ends of the scaffold plank, to which the connecting hooks 14 are fastened for hanging in the scaffold.
Ferner ist aus Fig. 1 zu erkennen, daß die durch das obere Blechprofil 3 gebildete Oberseite 2 mit zur Oberseite hin gerichteten Einprägungen 15 versehen ist. Die einzelnen Einprägungen 15 weisen eine größere Länge als Breite auf und sind in einem Fischgrätenmuster angeordnet. Die Längsorientierung des Fischgrätenmusters, die durch den Pfeil 0 gekennzeichnet ist, schließt mit der Längsrichtung der Gerüstbohle l einen Winkel ein. Das bewirkt, daß die Einprägungen 15 im Bereich der Längsränder nicht über eine längere Strecke gleichgerichtet sind, wodurch die Rutschsicherheit erhöht wird. Ferner läuft auch keine geschlossene Linie in Querrichtung der Gerüstbohle, so daß eine "Sollknickstelle" durch die Einprägungen 15 nicht provoziert wird.It can also be seen from FIG. 1 that the upper side 2 formed by the upper sheet metal profile 3 is provided with impressions 15 directed towards the upper side. The individual impressions 15 have a greater length than width and are arranged in a herringbone pattern. The longitudinal orientation of the herringbone pattern, which is indicated by the arrow 0, includes an angle with the longitudinal direction of the scaffold plank 1. This has the effect that the impressions 15 in the area of the longitudinal edges are not aligned over a longer distance, which increases the slip resistance. Furthermore, there is no closed line in the transverse direction of the scaffold plank, so that a "predetermined kink" is not provoked by the impressions 15.
Im folgenden wird die Wirkungs- und Funktionsweise der erfindungsgemäßen Gerüstbohle näher erläutert.In the following, the action and function of the scaffold screed according to the invention is explained in more detail.
Zur Herstellung der Gerustbohle werden zunächst getrennt voneinander das obere Blechprofil 3 und das untere Blechprofil 4 hergestellt. Nachdem beide Blechprofile auf gleiche Länge abgelängt wurden, wird das untere Blechprofil 4 in das obere Blechprofil 3 in Längsrichtung der Gerustbohle 1 eingeschoben, wobei die Längsränder 7 des unteren Blechprofiles von den Längsrändern des oberen Blechprofiles 3 umgriffen werden. Anschließend wird das obere Blechprofil 3 mit dem unteren Blechprofil im Bereich der Wellenberge 5 desselben verstanzt. Schließlich werden auf die stirnseitigen Enden die Querprofile 13 aufgesteckt und vernietet. Anschließend werden die Kammern 12 und 12' mit Polyurethanschaαm ausgeschäumt', der während des Aushärtens expandiert und die Hohlräume vollständig ausfüllt und sich auch von unten in die Einprägungen 15 drückt, was eine zusätzliche Aussteifung der Gerustbohle 1 bewirkt. Durch das Expandieren des Polyurethanschaums in den Kammern 12' wird die Hakenlasche 11 fest in die Sicke 17 des unteren Blechprofils gedrückt, wodurch sich eine stabile Verbindung der Längsränder des oberen und des unteren Blechprofils und gleichzeitig eine wirksame Abdichtung gegen austretenden Schaum ergibt.To produce the scaffold planks, the upper sheet metal profile 3 and the lower one are first separated from one another Sheet profile 4 made. After both sheet profiles have been cut to the same length, the lower sheet profile 4 is pushed into the upper sheet profile 3 in the longitudinal direction of the scaffold plank 1, the longitudinal edges 7 of the lower sheet profile being encompassed by the longitudinal edges of the upper sheet profile 3. Then the upper sheet profile 3 is punched with the lower sheet profile in the area of the wave crests 5 of the same. Finally, the cross sections 13 are plugged onto the front ends and riveted. Subsequently, the chambers 'foamed with Polyurethanschaαm' 12 and 12, which expands during curing and completely fills the cavities and also presses from below into the indentations 15, which causes an additional stiffening of the Gerustbohle. 1 By expanding the polyurethane foam in the chambers 12 ', the hook tab 11 is pressed firmly into the bead 17 of the lower sheet profile, resulting in a stable connection of the longitudinal edges of the upper and lower sheet profiles and at the same time an effective seal against escaping foam.
Das zur Herstellung der Gerustbohle verwendete Blech ist vorzugsweise ein differenzverzinktes Stahlblech, wobei die Blechstärke des unteren Blechprofils je nach Breite, Länge und Anforderung an die Gerüstbohle im Bereich von 0,3 bis 1 mm liegen kann, während sich die Blechstärke des oberen Blechprofils nach der geforderten Durchstoßfestigkeit richtet und eher oberhalb von 0,5 mm liegen sollte.The sheet used to manufacture the scaffold plank is preferably a galvanized steel sheet, the sheet thickness of the lower sheet profile depending on the width, length and requirements of the scaffold plank can be in the range of 0.3 to 1 mm, while the sheet thickness of the upper sheet profile can vary according to required puncture resistance and should rather be above 0.5 mm.
Figur 4 zeigt eine Variante einer Gerüstbohle l, die mit der zuvor beschriebenen Gerustbohle in allen wesentlichen Merkmalen übereinstimmt, weshalb für gleiche und gleichartige Bauteile identische Bezugszeichen verwendet werden. I Unterschied zu der zuvor beschriebenen Gerustbohle sind die Einprägungen 15 nicht in Form eines Fischgrätmusters angeordnet. Bei der Variante gemäß Fig. 4 sind die Einprägungen vielmehr in Form von in Längsrichtung und Querrichtung der Gerüstbohle gegeneinander versetzt angeordneten Kreuzen ausgebildet, deren freie Enden 16 in einprägungsfreie Abschnitte der Oberseite 2 der Gerüstbohle übergehen. Auch hierdurch wird vermieden, daß die Einprägungen in Form einer geschlossenen Richtung in Querrichtung oder Längsrichtung der Gerustbohle verlaufen.FIG. 4 shows a variant of a scaffold plank 1 which corresponds in all essential features to the scaffold plank described above, which is why identical reference numerals are used for identical and similar components. Unlike the scaffold plank described above, the impressions 15 are not arranged in the form of a herringbone pattern. In the variant according to FIG. 4, the impressions are rather in the form of crosses arranged offset with respect to one another in the longitudinal and transverse directions of the scaffolding planks, the free ends 16 of which merge into sections of the top side 2 of the scaffolding plank free of embossing. This also avoids that the impressions run in the form of a closed direction in the transverse or longitudinal direction of the screed.
In Figur 5 ist eine weitere Variante einer Gerüstbohle dargestellt, die ebenfalls mit den zuvor beschriebenen Gerüstbohlen in allen wesentlichen Merkmalen übereinstimmt, weshalb ebenfalls für gleiche und gleichartige Bauteile identische Bezugszeichen verwendet werden. Im Unterschied zu den vorherigen Varianten sind die Einprägungen in Form von gegeneinander versetzten Sternchenmustern vorgesehen. Es handelt sich hier um einzelne Einprägungen 15, die verschiedene Orientierungen aufweisen und jeweils in Gruppen zu Sternen gruppiert sind, die gegeneinander versetzt angeordnet sind. FIG. 5 shows a further variant of a scaffold plank, which also corresponds in all essential features to the scaffold planks described above, which is why identical reference numerals are also used for identical and similar components. In contrast to the previous variants, the embossments are provided in the form of star patterns offset from one another. These are individual impressions 15 which have different orientations and are each grouped in groups to form stars which are arranged offset from one another.
