Description

Die Erfindung betrifft einen Gerüstboden mit an gegenüberliegenden Endseiten befestigten Einhängeeinrichtungen mit folgenden Merkmalen:

  • Tragelement und Lauffläche sind von ggf. blockverleimten Massivholzbrettern gebildet;
  • auf die Enden der Massivholzbretter sind Blechkappen mit stirnseitig angebrachten Einhängekrallen aufgesteckt;
  • die Blechkappen sind U-förmig ausgebildet;
  • die Blechkappen sind mit sich durch die Massivholzbretter erstreckenden Nieten daran befestigt.
The invention relates to a scaffolding floor with hanging devices attached to opposite end sides with the following features:
  • Carrying element and running surface are formed from possibly block-glued solid wood boards;
  • sheet metal caps with hook-on claws on the front are attached to the ends of the solid wood boards;
  • the sheet metal caps are U-shaped;
  • the sheet metal caps are attached to it with rivets extending through the solid wood boards.

Gerüstböden werden seit eh und je als Massivholzbohlen ausgebildet. Früher wurden sie stirnseitig einfach abgeschnitten und auf die Leitern oder sonstigen Tragteile aufgelegt, so daß man beim Montieren und Benutzen stets sehen konnte, ob die Enden verrottet sind oder nicht und ob wohl die Tragfähigkeit ausreicht.Scaffolding floors have always been designed as solid wooden planks. In the past, they were simply cut off on the front and placed on the conductors or other supporting parts, so that when assembling and using, you could always see whether the ends were rotten or not and whether the load-bearing capacity was sufficient.

In zunehmendem Maße werden mit metallenen Rahmen aus Stahl und/oder Leichtmetall und/oder im ganzen aus Stahl und/oder Leichtmetall aufgebaute Gerüstböden verwendet, so daß der Benutzer nicht mehr gewohnt ist, auf die Verrottung von Gerüstböden zu achten.Increasingly, metal and steel frames and / or light metal and / or steel and / or light metal scaffolding floors are used so that the user is no longer used to paying attention to the rotting of scaffolding floors.

Viele Benutzer bevorzugen für viele Einsatzzwecke jedoch Gerüstböden aus Massivholz. Da Massivholz in der erforderlichen Breite nicht mehr in ausreichendem Masse zu annehmbaren Preisen zur Verfügung steht, werden Massivholz-Gerüstböden aus nebeneinander mit Spalten liegenden oder unmittelbar aneinander geleimten Massivholzbrettern hergestellt, die als blockverleimte Massivholzbretter bezeichnet werden. In genormten Gerüstsystemen verwendet man genormte Einhängemittel. Diese enthalten in der Regel stirnseitig angebrachte Einhängekrallen, die man in nach oben offene U-Profile der Tragelemente gut einhängen und vor allem darin sichern kann. Solche Einhängekrallen werden an metallenen Rahmen oder Gerüstböden direkt angebracht. Zur Anbringung passender Einhängekrallen an Massivholzbrettern verwendet man Blechkappen, die als U-förmig gebogene Blechteile mit gleichen Schenkellängen ausgebildet sind und an dem vertikal stehenden stirnseitigen Steg die Einhängekrallen aufweisen. Diese Blechkappen werden mit durchgehenden Nieten nach dem Aufstecken auf die Enden der Massivholzbretter an diesen befestigt. Damit man eine gute, festsitzende Anlage und eine sichere Verbindung erzielt, hat man die Blechkappen bisher vollflächig auf den Enden der Massivholzbretter ggf. nach Verringerung der Stärke um die Stärke der Schenkel befestigt.However, many users prefer scaffolding floors made of solid wood for many purposes. Since solid wood in the required width is no longer available in sufficient quantities at acceptable prices, solid wood scaffolding floors are made from solid wood boards lying next to one another with gaps or glued directly to one another, which are called block-glued solid wood boards. Standard suspension devices are used in standardized scaffolding systems. As a rule, these contain hook-in claws on the front, which can be easily hooked into the U-profiles of the support elements that are open at the top and, above all, secure in them. Such hanging claws are attached directly to metal frames or scaffolding floors. Sheet metal caps, which are U-shaped, are used to attach suitable claws to solid wood boards curved sheet metal parts are formed with the same leg lengths and have the hooking claws on the vertical end web. These sheet metal caps are fastened to the ends of the solid wood boards with continuous rivets after they have been attached. In order to achieve a good, tight fit and a secure connection, the sheet metal caps have previously been fixed over the entire surface of the ends of the solid wood boards, possibly after reducing the thickness by the thickness of the legs.

Aus EP-A-0 017 957 ist ein etwas anders gestalteter Gerüstboden bekannt, der als aus einzelnen Dielen bestehende Arbeitsbühne bei Gerüsten bezeichnet ist. Dabei sind auf die Enden der Massivholzbretter ohne Verjüngung derselben aus Strang-Preß-Profilen geformte U-förmige Kappen mit angeformten Auflagehaken für Horizontalrohre als Tragmittel befestigt. Auch diese U-Profile sind dreiseitig geschlossen und lassen das Eindringen und Halten von Wasser sowie die entsprechende Verrottung zu. Man kann weder die Enden sehen noch ist eine Belüftung vorgesehen und möglich.From EP-A-0 017 957 a somewhat differently designed scaffolding floor is known, which is referred to as a working platform consisting of individual planks for scaffolding. In this case, U-shaped caps with molded support hooks for horizontal tubes are attached to the ends of the solid wood boards without tapering them from extruded profiles. These U-profiles are also closed on three sides and allow water to penetrate and hold, as well as rotting. You can neither see the ends nor ventilation is provided and possible.

Da Gerüste im Freien verwendet werden, dringt stets Feuchtigkeit in die Enden der Massivholzbretter ein. Da die Blechkappen oder sonstige U-Profile geschlossen sind, kann es in den eingeschlossenen Enden der Massivholzbretter zu Moderfäule kommen. Solche Verrottungen lassen sich nurschwer beobachten, weil die Randbereiche, die aus den Blechkappen herausstehen, noch vollkommen unbeschädigt aussehen. Trotzdem hat die Festigkeit in diesen hoch belasteten Endbereichen erheblich abgenommen und es besteht die Gefahr des Abbrechens der verrotteten Enden mit den Blechkappen.Since scaffolding is used outdoors, moisture always penetrates the ends of the solid wood boards. Since the sheet metal caps or other U-profiles are closed, mold rot can occur in the enclosed ends of the solid wood boards. Such rotting is difficult observe because the edge areas that protrude from the sheet metal caps still look completely undamaged. Nevertheless, the strength in these highly stressed end areas has decreased considerably and there is a risk of the rotted ends breaking off with the sheet metal caps.

Der Erfindung liegt die Aufgabe zugrunde, Gerüstböden aus Massivholz verfügbar zu machen, deren Enden auch bei Feuchtigkeitsaufnahme gestatten, daß die Feuchtigkeit schnell wieder abgegeben wird und bei denen die Endbereiche, an denen die Befestigung vorgenommen wird, stets gut sichtbar bleiben.The invention has for its object to make scaffolding floors made of solid wood available, the ends of which, even when absorbing moisture, allow the moisture to be released quickly and in which the end regions to which the attachment is made always remain clearly visible.

Dazu sieht die Erfindung die folgenden Merkmale vor:

  • die Blechkappen haben in allen Flächenbereichen der Ober-Schenkel und Unter-Schenkel sowie des stirnseitigen Steges, in denen sie von Befestigungseinrichtungen frei sind, Belüftungsdurchbrechungen;
  • die Belüftungsdurchbrechungen haben unterschiedliche, der jeweils verfügbaren Fläche entsprechende Größe und/oder Form.
To this end, the invention provides the following features:
  • the sheet metal caps have ventilation openings in all surface areas of the upper leg and lower leg and of the end web, in which they are free from fastening devices;
  • the ventilation openings have different sizes and / or shapes corresponding to the available area.

Es ist von besonderer Bedeutung, daß die Blechkappen in allen Flächenbereichen der Ober-Schenkel und Unter-Schenkel sowie des stirnseitigen Steges, in denen sie von Befestigungseinrichtungen frei sind, Belüftungsdurchbrechungen haben. Diese können auch als profilierte Ausprägungen ausgestaltet sein. Man dimensoniert das Blech so, daß die tragenden Teile auf schmale Streifen oder profilierte Restbereiche konzentriert sind, während die Flächen soweit als möglich Durchbrechungen aufweisen, so daß eingedrungene Feuchtigkeit schnell wieder austreten kann und die Kapillarwirkung nicht die Feuchtigkeit unter größeren Flächenbereichen für längere Zeit festhält, was die Wachstumsbedingungen für Mikroorganismen fördern würde und somit zur Verrottung der Massivholzenden führen würde. Die Belüftungsdurchbrechungen können dabei unterschiedliche, der jeweils verfügbaren Fläche entsprechende Größe und/oder Form haben. So kann man sich den Gegebenheiten der jeweiligen Gerüstkonstruktion ohne Schwierigkeiten anpassen. Dabei ist es besonders zweckmässig, wenn jeder einzelne Gerüstboden etwa 32 cm breit ist, weil er dann nicht zu schwer für die häufige Handhabung wird und weil andererseits zwei Gerüstböden nebeineinanderliegend für die üblichen Gerüsttiefen mit einem Grundmaß von 70 cm verwendet werden konnen und bei drei nebeneinanderliegenden Gerüstböden das vielfach verwendete Mass von 1 m erreicht wird, man andererseits die Gerüstböden dieser Breite auch allein oder zu mehreren nebeneinander als Konsolbohlen verwenden kann.It is of particular importance that the sheet metal caps have ventilation openings in all surface areas of the upper leg and lower leg as well as of the end web in which they are free of fastening devices. These can also be designed as profiled forms. The sheet is dimensioned so that the load-bearing parts are concentrated on narrow strips or profiled remaining areas, while the Surfaces have openings as far as possible so that penetrated moisture can escape again quickly and the capillary action does not hold the moisture under large surface areas for a long time, which would promote the growth conditions for microorganisms and thus lead to the rotting of the solid wood ends. The ventilation openings can have different sizes and / or shapes corresponding to the available area. So you can easily adapt to the conditions of the respective scaffolding construction. It is particularly useful if each individual scaffold floor is about 32 cm wide, because then it will not become too heavy for frequent handling and because, on the other hand, two scaffold floors can be used next to each other for the usual scaffold depths with a basic dimension of 70 cm and with three adjacent Scaffolding floors the commonly used dimension of 1 m is reached, on the other hand, the scaffolding floors of this width can also be used alone or in groups next to each other as bracket planks.

Ein weiteres wichtiges Merkmal der Erfindung sieht vor, daß daß die Blechkappen für unterschiedlich dicke Massivholz-Bretter aus dem gleichen Zuschnitt mit zu den Kanten gleicher Lage der Löcher, jedoch im Abstand unterschiedlich liegender Abkantung von dem stirnseitigen Steg gebildet sind und dafür mit ihren schmal ausgebildeten, weit auf die Holzfläche ragenden Befestigungslaschen geringer Breite und einem unterschiedlichen breiten gelochten Kantenbereich gestaltet sind. So kann man sich den Festigkeitsbedürfnissen unterschiedlich dicker Bretter bei gleichbleibenden Herstellungswerkzeugen für die jeweilige Breite der Blechkappe einfach anpassen.Another important feature of the invention provides that the sheet metal caps for solid wood boards of different thicknesses are formed from the same blank with the same position of the holes as the edges, but with a different chamfer at a distance from the front web and therefore with their narrow design , fastening tabs of small width and of different widths that protrude far onto the wooden surface perforated edge area are designed. So you can easily adapt to the strength requirements of boards of different thicknesses with the same manufacturing tools for the respective width of the sheet metal cap.

Die Befestigung der Blechkappen auf den Enden der Bretter kann auf verschiedene Weise bewirkt werden, je nachdem, was die Festigkeitsverhältnisse und der Bearbeitungsaufwand für sinnvoll erscheinen lassen. Dabei können die Oberflächen der Ober-Schenkel und ggf. der Unter-Schenkel der Blechkappen in den Oberflächenebenen der Massivholzbretter liegen, so daß Vertiefungen am Ende in die Massivholzbretter eingearbeite werden oder man kann die inneren Auflageflächen der Ober-Schenkel und ggf. der Unter-Schenkel der Blechkappen auf den eben durchgeführten Oberflächen der Massivholzbretter aufliegen lassen. So kann die Bearbeitung vereinfacht werden und die Gefahr von Stolperstellen ist wegen sinnvoller dünner Blechwahl nicht so groß, kann jedoch durch Vertiefung verringert werden. Eine weitere Ausgestaltung im Rahmen der Aufgabe, die Verrottung zu verhindern und Belüftungsmöglichkeiten zu schaffen, sieht vor, daß die Niete für die Befestigung der Blechkappen an der Oberseite jeweils mit einem Rundkopf und an der Unterseite jeweils mit einer Vertiefung ausgebildet sind, so daß sich beim Stapeln die Vertiefungen der Nieten jeweils oben liegender Gerüstböden auf den runden Kuppen der Nietköpfe der jeweils darunter liegenden Gerüstböden jeweils einen Belüftungs-Zwischenraum zwischen den Massivholzbrettern bildend abstützen.The fastening of the sheet metal caps on the ends of the boards can be effected in different ways, depending on what makes the strength conditions and the processing effort seem reasonable. The surfaces of the upper legs and, if applicable, the lower legs of the sheet metal caps can lie in the surface levels of the solid wood boards, so that indentations are worked into the solid wood boards at the end, or the inner contact surfaces of the upper legs and possibly the lower Let the legs of the sheet metal caps rest on the surfaces of the solid wooden boards that have just been passed through. Processing can be simplified and the risk of stumbling is not so great due to the sensible choice of thin sheet metal, but it can be reduced by deepening it. Another embodiment within the scope of the task to prevent rotting and to provide ventilation, provides that the rivets for fastening the sheet metal caps are each formed with a round head on the top and with a recess on the bottom, so that when Stack the recesses of the rivets on the top of each scaffold floor to support the round ridges of the rivet heads of the scaffold floors underneath each, forming a ventilation space between the solid wood boards.

These are, as can best be seen from FIG. 5, bent into U-shaped components and have an upper leg 14.1 and a lower leg 14.2 and a web 14.3. The latter forms the end face. In the area of its ends it carries two known hook-in claws 15.1 and 15.2 which are open at the bottom and which are welded on.

Wie aus den Fig. 1, 3 und 4 ersichtlich, sind in den Ober-Schenkeln 14.1 und Unter-Schenkeln 14.2 jeweils vier Befestigungslöcher 16.1 bis 16.4 im Bereich der äußersten Enden angebracht. Durch diese werden - wegen der Kleinheit der Darstellung nicht sichtbare - Nieten geführt, nachdem die Blechkappen 12 auf die Enden 13.1 und 13.2 der Massivholzbretter 11 gesteckt sind. Damit die Oberflächen 12.4 der Blechkappen 12 und die Oberfläche 11.4 der Massivholzbretter miteinander fluchten und keine Stolperstellen entstehen, sind die Enden 13.1 und 13.2 der Massivholzbretter, wie aus den Fig. 1 und 2 ersichtlich, um die Wandstärke der Blechkappen abgefräst, so daß die Blechkappen in dünneren Bereichen aufgesteckt sind.As can be seen from FIGS. 1, 3 and 4, four fastening holes 16.1 to 16.4 are made in the region of the outermost ends in the upper legs 14.1 and lower legs 14.2. Because of the smallness of the illustration, rivets are guided through these after the sheet metal caps 12 have been placed on the ends 13.1 and 13.2 of the solid wood boards 11. So that the surfaces 12.4 of the sheet metal caps 12 and the surface 11.4 of the solid wood boards are flush with one another and no stumbling points occur, the ends 13.1 and 13.2 of the solid wood boards are milled, as can be seen from FIGS. 1 and 2, by the wall thickness of the sheet metal caps, so that the sheet metal caps are attached in thinner areas.

Wie aus den Fig. 1, 3 und 4 ersichtlich, sind alle Flächenbereiche der Blechkappen 12, die nicht für die Befestigung benötigt werden, mit Belüftungsdurchbrechungen 17 versehen. Diese sind in versetzten Reihen und/oder mit unterschiedlicher Größe ausgebildet, je nachdem wie es die Festigkeitsbedürfnisse erfordern. Dabei sind die Bereiche 18.1 und 18.2 zwischen den äußeren Befestigungsschenkeln 14.4 und 14.5 trapezförmig ausgestanzt, während der Mittelbereich der Oberschenkel 14.1 und der Unterschenkel 14.2 zwischen den Befestigungslöchern 16.2 und 16.3 stehen geblieben ist, um hier Stabilität zu schaffen. Dafür weist er eine größere Belüftungsdurchbrechung 17 auf. Auch die stirnseitig dicht an den Enden der Massivholzbretter 11 anliegenden Stege 14.3 sind zwichen den Einhängekrallen 15.1 und 15.2 mit Belüftungsdurchbrechungen 17 unterschiedlicher Größe versehen. Wie ersichtlich, sind die Wege für die Feuchtigkeit unter den Blechflächen bis hin zu den Enden oder den Belüftungsöffnungen sehr kurz, so daß eingedrungene Feuchtigkeit wegen der Poren im Holz gut austreten kann und somit der Verrottung vorgebeugt ist. Außerdem kann man durch die Belüftungsdurchbrechungen 17 das Holz beobachten. Es kommen auch andere Lochformen und Lochgestaltungen sowie Lochanordnungen für die Belüftungsdurchbrechungen in Frage. Auch können die Blechkappen mit anderen Einhängekrallen versehen sein oder andersartig ausgestaltet sein.As can be seen from FIGS. 1, 3 and 4, all surface areas of the sheet metal caps 12 that are not required for fastening are provided with ventilation openings 17. These are formed in staggered rows and / or with different sizes, depending on how the strength requirements require. The areas 18.1 and 18.2 between the outer fastening legs 14.4 and 14.5 are punched out in a trapezoidal manner, while the middle region of the thighs 14.1 and lower legs 14.2 has remained between the fastening holes 16.2 and 16.3 in order to create stability here. For this purpose, it has a larger ventilation opening 17. The webs 14.3 lying close to the ends of the solid wood boards 11 are also provided with ventilation openings 17 of different sizes between the hooking claws 15.1 and 15.2. As can be seen, the paths for the moisture under the sheet metal surfaces to the ends or the ventilation openings are very short, so that moisture which has penetrated can escape well because of the pores in the wood and thus prevent rotting. In addition, the wood can be observed through the ventilation openings 17. Other hole shapes and hole designs as well as hole arrangements for the ventilation openings are also possible. The sheet metal caps can also be provided with other hooking claws or be configured differently.

Das Ausführungsbeispiel der Fig. 6 und 7 zeigt eine sehr ähnliche Blechkappe 22. Gleichartige Teile sind mit gleichen Bezugzeichen versehen. Diese Blechkappe 22 ist für breitere Gerüstböden gestaltet und hat deshalb in der Mitte noch eine weitere Einhängekralle 15.3. Im übrigen sind hier nicht nur zwei außen liegende Befestigungslaschen 24.1 und 24.2 und ein mittlerer Befestigungsschenkel-Bereich 24.3, sondern dazwischen liegend weitere Befestigungslaschen 24.4 und 24.5 an den Ober-Schenkeln 14.1 und Unter-Schenkeln 14.2 gebildet, und zwar durch Ausstanzung der trapzeförmigen Bereiche 18.1 und 18.2 sowie durch Ausstanzung weiterer Freibereiche 18.3 und 18.4. Die freie Länge 26 der Befestigungslaschen 24.1 bis 24.5 ist hier - wie aus den Zeichnungen ersichtlich - wesentlich größer gewählt als bei dem ersten Ausführungsbeispiel. Trotzdem ist die vom geschlossenen Blech bedeckte Fläche nicht nennenswert größer, vor allem in Bezug auf die gesamte Holzfläche, weil wesentlich mehr und wesentlich größere Belüftungs-Durchbrechungen 17 vorgesehen sind. In manchen Flächenbereichen, sowohl des Steges 14.3 als auch des mittleren Befestigungsschenkel-Bereiches 24.3 sind keine Durchbrechungen, sondern Hohlräume bildende Ausprägungen 27 vorgesehen. Diese bilden unter dem Blech hinreichende Hohlräume, daß keine Kapillarwirkung eintreten kann, so daß das Wasser nicht gehalten wird. Solche Ausprägungen 27 können auch in Form von Firmenzeichen, Namen oder Kennzeichnungen für die Materialerfassung gestaltet sein. Im übrigen ist die Gestaltung von lochfreien Bereichen und Bereichen mit Durchbrechungen so gewählt, daß man die Ober-Schenkel 14.1 und Unter-Schenkel 14.2 mit unterschiedlichem Abstand 28 voneinander von dem Steg 14.3 abkanten kann, ohne daß man für die Blechkappen für unterschiedlich starke Bretter verschiedene Platinen und deshalb verschiedene Stanzwerkzeuge benutzen müßte. Dadurch wird eine wesentliche Herstellungsvereinfachung erzielt und man kann für Gerüstböden größerer Länge ohne weiteres dickere Holzbretter verwenden.The embodiment of FIGS. 6 and 7 shows a very similar sheet metal cap 22. Parts of the same type are provided with the same reference numerals. This sheet metal cap 22 is designed for wider scaffolding floors and therefore has a further hanging claw 15.3 in the middle. Incidentally, here not only two outer fastening tabs 24.1 and 24.2 and a middle fastening leg area 24.3, but also intermediate fastening tabs 24.4 and 24.5 are formed on the upper legs 14.1 and lower legs 14.2 by punching out the trapezoidal areas 18.1 and 18.2 and by punching out further open areas 18.3 and 18.4. The free length 26 of the fastening tabs 24.1 to 24.5 is chosen here — as can be seen from the drawings — to be substantially greater than in the first exemplary embodiment. Nevertheless, the area covered by the closed sheet metal is not appreciably larger, especially with respect to the entire wooden area, because significantly more and substantially larger ventilation openings 17 are provided. In some surface areas, both of the web 14.3 and of the central fastening leg area 24.3, there are no perforations, but instead cavities 27 are provided. These form sufficient cavities under the sheet metal that no capillary action can occur, so that the water is not held. Such expressions 27 can also be designed in the form of company logos, names or markings for the material detection. For the rest, the design of Hole-free areas and areas with openings are selected so that the upper legs 14.1 and lower legs 14.2 can be bent at a different distance 28 from one another from the web 14.3 without using different boards and therefore different stamping tools for the sheet metal caps for boards of different thicknesses ought to. This results in a significant simplification of manufacture and one can use thicker wooden boards for scaffolding floors of greater length without further notice.

Die Fig. 8 zeigt die Enden zweier Gerüstböden 1O.1 und 1O.2 mit den Blechkappen 12.6 und 12.7, die wie in den Fig. 3 bis 5 oder 6 und 7 ausgebildet sind. Die Ober-Schenkel 14.1 und die Unter-Schenkel 14.2 liegen im Gegensatz zu den Darstellungen der Fig. 1 und 2 mit ihren inneren Auflageflächen 21.1 und 21.2 auf den an den Enden nicht ausgenommenen Oberflächen 11.5 der Massivholzbretter 11 glatt auf.FIG. 8 shows the ends of two scaffolding floors 10.1 and 10.2 with the sheet metal caps 12.6 and 12.7, which are designed as in FIGS. 3 to 5 or 6 and 7. In contrast to the representations of FIGS. 1 and 2, the upper legs 14.1 and the lower legs 14.2 lie smoothly with their inner bearing surfaces 21.1 and 21.2 on the surfaces 11.5 of the solid wood boards 11 which are not recessed at the ends.

Zur Befestigung dienen Niete 2O, die sich durch die Befestigungslöcher 16.1 bis 16.6 erstrecken. Diese sind in üblicher Weise als verformbare Metallkörper ausgebildet und haben jeweils ein halbrunden Kopf 2O.1. Sie sind nun jedoch an der Unterseite nicht wie bisher mit einem halbrunden Kopf vernietet, sondern mit einer Vertiefung 2O.2 ausgestattet, die sich innerhalb eines Randkragens 2O.3 befindet. Das ist mit geeigneten Nietwerkzeugen einfach und mit guter Präzision zu machen. So kann sich der Rand 2O.4 der Vertiefung 2O.2 eines oberen Gerüstbodendens 1O.2 auf dem gerundeten Kopf 2O.1 des Nietes des darunter liegenden Gerüstbodens 1O.1 abstützen. Es wird ein großer Belüftungsraum 25 geschaffen, der die Bohlen gut austrocknen läßt. Durch die Nieten mit ihrer speziellen Ausbildung lassen sich die Bohlen auch gut geordnet stapeln und es wird verhindert, daß sie in Teilbereichen Berührung miteinander haben, so daß sich Wasser in Kapiallarschichten sammeln könnte, wie es bisher vielfach geschah und zur Verrottung führte. Die halbrunden Köpfe 2O.1 der Nieten sind vorzugsweise so hoch ausgeführt, daß auch in solchen Fällen, in denen nicht ordnungsgemäß auf den Vertiefungen 2O.1 abgestütz wird, der Belüftungsraum 25 noch ausreicht, um Berührungen zu vermeiden. Die Enden der Befestigungslaschen 24.1 bis 24.5 sind gerundet und dünn, so daß auch bei unmittelbarer Auflage auf der Oberfläche 11.4 ohne Vertiefung praktisch keine die Benutzung behindernden Stolperstellen entstehen. Auch die gerundeten Köpfe 2O.1 sind so gestaltet, daß die Benutzung nicht behindert wird.Rivets 2O, which extend through the fastening holes 16.1 to 16.6, are used for fastening. These are designed in the usual way as deformable metal bodies and each have a semicircular head 20.1. However, they are now not riveted to the underside with a semicircular head as before, but are equipped with a recess 2O.2, which is located within an edge collar 2O.3. This can be done easily and with good precision using suitable riveting tools. Thus, the edge 2O.4 of the recess 2O.2 of an upper scaffold floor 10.2 Support the rounded head 2O.1 of the rivet of the scaffolding floor 1O.1 below. A large ventilation space 25 is created which allows the planks to dry out well. Due to the rivets with their special design, the planks can also be stacked in an orderly manner and it is prevented that they come into contact with each other in some areas, so that water could collect in capital layers, as has been the case so far and has led to rotting. The semicircular heads 2O.1 of the rivets are preferably so high that even in those cases in which the recesses 2O.1 are not properly supported, the ventilation space 25 is still sufficient to avoid contact. The ends of the fastening tabs 24.1 to 24.5 are rounded and thin, so that even when placed directly on the surface 11.4 without a depression, there are practically no stumbling blocks which hinder use. The rounded heads 2O.1 are also designed so that use is not hindered.
