Description
Die Erfindung bezieht sich auf einen Kunststoffhalter mit KopfThe invention relates to a plastic holder with a head
und Schaft.and shaft.
Im Flachdachbau, bei dem Kunststoff-Folien zur Abdichtung und eine darunter liegende Dämmschicht zur Wärmedämmung verwendet werden, befestigt man Folie und Dämmung mittels eines flachen Metallhalters, versehen mit einer Bohrung für die zur Befestigung notwendige Schraube.In flat roof construction, where plastic foils for sealing and a If the insulation layer underneath is used for thermal insulation, foil is attached and insulation by means of a flat metal holder provided with a hole for the screw required for fastening.
Weiter gibt es flach- runde bzw. flach- ovale Kunststoffhalter mit Schaft zur Aufnahme der für die Befestigung notwendigen Schraube. Diese Halter, seien sie aus Kunststoff oder Metall, werden anschließend durch die überlappende Dachfolie abgedeckt.There are also flat-round or flat-oval plastic holders Shank to accommodate the screw required for fastening. These holders, be they made of plastic or metal, are then followed by the overlapping Roofing membrane covered.
Diese an sich genügende mechanische Befestigung von Foliendämmung hat folgende Nachteile: 1. Der Metallhalter weist das Problem der Korrosion und Scharfkantigkeit aus. Das bedeutet a) die im Dachaufbau immer vorhandene Feuchtigkeit führt zu einer Korrosion an Halter und Schraube.This mechanical fastening of foil insulation, which is sufficient in itself has the following disadvantages: 1. The metal holder has the problem of corrosion and Sharpness. This means a) the moisture that is always present in the roof structure leads to corrosion on the holder and screw.
b) Weiterhin ist der Halter aus Metall fertigungsbedingt scharfkantig Ein Flachdach ist durch die laufenden Temperaturschwankungen laufenden Bewegungen unterworfen. b) Furthermore, the metal holder is sharp-edged due to the manufacturing process A flat roof is subject to constant movements due to constant temperature fluctuations subject.
Der starr befestigte Halter übt dadurch eine Scherbewegung auf die Folie aus, was mittel- und langfristig zum Zerreißen bzw. Zerschneiden der Folie führt. The rigidly attached holder thereby exerts a shear movement on the Foil from what medium and long term to tear or cut the foil leads.
Ein weiterer Nachteil des Metallhalters ist die Tatsache, daß die starr mit dem Dach verbundene Schraube durch den Metallhalter hindurchrutscht und dabei die Kunststoff-Folie durchstoßen kann. Another disadvantage of the metal holder is the fact that the screw rigidly connected to the roof slips through the metal holder and can pierce the plastic film.
2. Die bisher vorhandenen Kunststoffhalter weisen ebenfalls wesentliche Nachteile auf.2. The previously existing plastic holders also have essential Disadvantages on.
a) Der runde Kunststoffhalter hat einen kreisrunden Kopf mit ca. 35 cm Durchmesser, der aber den Richtlinien des Dachdeckerhandwerkes im Flachdachbau mit Folien nicht entspricht.a) The round plastic holder has a circular head with approx. 35 cm in diameter, but in accordance with the guidelines of the roofing trade in flat roof construction does not correspond with foils.
b) Der ovale Kunststoffhalter hat folgende Nachteile: Beim Einschrauben verformt sich der Kopf des Kunststoffhalters konkav nach außen. Dadurch liegen die Enden des Kopfes des Kunststoffhalters nicht flach auf der Kunststoff-Folie auf, sondern stehen nach oben ab.b) The oval plastic holder has the following disadvantages: When screwing in the head of the plastic holder is deformed concavely outwards. As a result, the The ends of the head of the plastic holder are not flat on the plastic film, but stand up from the top.
Entsprechend der Verlegung beim Metallhalter führt dieser abgehobene Teil des Kunststoffhalters bei der notwendigen Wärmeausdehnung des Daches zu Scherbewegungen, die eine Verletzung des Daches bewirken. Corresponding to the routing of the metal holder, this lifted one leads Part of the plastic holder with the necessary thermal expansion of the roof to shear movements, causing damage to the roof.
Weiterhin wird beim Begehen des Daches damit eine Gefahr für den Dachbauaufbau hinsichtlich des Durchtretens der Dachfolie an dieser Stelle gegeben. Furthermore, when walking on the roof there is a danger for the Roof construction given with regard to the penetration of the roof membrane at this point.
Weiterhin weist dieser Kunststoffhalter an der Stelle zwischen Kopf und Schaft vier stegartige Verstärkungen auf, die scharfkantig sind. Beim Einbau dieses Kunststoffhalters wird die Dachfolie an den Stellen der Verstärkungsstege beschädigt. Das bewirkt langfristig -bedingt durch die Wärmeausdehnung des Daches - ein Einreißen der Dachfolie an diesen Stellen. Weiterhin neigt dieser Kunststoffhalter beim mechanisierten Eindrehen der Schraube zum Zerschmelzen im Bereich der Spitze, da dort entsprechende Stabilisierungsstege fehlen. Furthermore, this plastic holder has at the point between the head and the shaft has four web-like reinforcements that are sharp-edged. During installation this plastic holder is the roofing membrane at the points of the reinforcement bars damaged. This has a long-term effect due to the thermal expansion of the roof - A tearing of the roof membrane in these places. Furthermore, this plastic holder is inclined with mechanized screwing in of the screw for melting in the area of the tip, since there are no corresponding stabilizing bars.
Weiterhin hat dieser Kunststoffhalter keine Stege zur Stabilisierung des Halters, so daß hinsichtlich der Ausreißsicherheit und Verdrehsicherheit keine Vorsorge getroffen wurde.Furthermore, this plastic holder has no webs for stabilization of the holder, so that in terms of security against pulling out and security against twisting, none Provision has been made.
Aufgabe der Erfindung war es, einen Kunststoffhalter der eingangs erwähnten Art zur Befestigung von Dachfolie und Dämmaterial zu schaffen, der eine einwandfreie Befestigung und Dichtung des Dachaufbaues über lange Zeiträume hinweg gewährleistet und der fertigungstechnisch und montagetechnisch leicht zu handhaben ist.The object of the invention was to provide a plastic holder of the initially To create mentioned type of fastening of roofing membrane and insulation material, the one Perfect fastening and sealing of the roof structure over long periods of time guaranteed and easy to handle in terms of production technology and assembly technology is.
Diese Aufgabe wird durch den Kunststoffhalter der eingangs erwähnten Art dadurch gelöst, daß der nach Schutzanspruch I bezeichnete Kunststoffhalter mit Kopf und Schaft als langovale, nach außen konvex gewölbte Platte ausgebildet ist und am Mantel des in einer konischen Spitze auslaufenden Schaftes zur Stabilisierung des Halters mindestens zwei axial verlaufende Stege aufweist.This task is achieved by the plastic holder mentioned at the beginning Art solved in that the plastic holder designated according to protection claim I with Head and shaft is designed as a long-oval, outwardly convex plate and on the jacket of the shaft ending in a conical tip for stabilization of the holder has at least two axially extending webs.
Zweckmäßige Ausführungsformen des Kunststoffhalter s der eingangs erwähnten Art sind in den Unteransprüchen gekennzeichnet.Appropriate embodiments of the plastic holder s initially mentioned type are characterized in the subclaims.
Der Kunststoffhalter der eingangs erwähnten Art hat eine langovale Platte, die durch eine leichte Krümmung eine Vorspannung aufweist und somit auf Folie und Dämmaterial einen Druck ausübt und damit die Niederhaltekraft verstärkt.The plastic holder of the type mentioned has a long oval Plate that has a bias due to a slight curvature and thus on Foil and insulation material exert pressure and thus increase the hold-down force.
Die an der Unterseite der langovalen Platte angebrachten Noppen sollen ein Verschieben oder Verrutschen der Folie verhindern. Die kreisförmige Verstärkung zwischen Kopf und Schaft soll ein Ausplatzen und Abreißen des Halterkopfes verhindern und dabei die befestigte Folie nicht verletzen.The knobs attached to the underside of the long oval plate should prevent the film from shifting or slipping. The circular reinforcement between head and shaft should prevent the holder head from bursting and tearing off and do not damage the attached film.
Weiter sind die am Schaft befestigten Verstärkungsstege ebenfalls dazu geeignet, ein Verdrehen des Kunststoffhalters zu verhindern, was sonst bei manueller wie motorischer Montage durch das auf die Schraube ausgeübte Drehmoment bewirkt wird.The reinforcement bars attached to the shaft are also there suitable for preventing the plastic holder from twisting, which would otherwise be the case manual and motorized assembly due to the torque exerted on the screw is effected.
Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Die dargestellte Figur zeigt eine Seitenansicht des Kunststoffhalters sowie einen Schnitt entlang der Linie A - A des erfindungsgemäßen Kunststoffhalters. Der einstückig gespritzte Kunststoffhalter besteht aus einem kegelförmigen Rundschaft (1') mit aufgesetztem langovalen Kopf (2), der nach außen hin konvex durchgebogen ist (2'). An der Unterseite der langovalen Platte sind kegelförmige Noppen (3) angeordnet. An der Verbindungsstelle zwischen Kopf und Schaft ist eine ringförmige Verstärkung angebracht (4), deren Radius größer ist als der Radius des Rundschaftes.The invention is based on an embodiment shown in the drawing explained in more detail. The figure shown shows a side view of the plastic holder and a section along the line A - A of the plastic holder according to the invention. The one-piece injection-molded plastic holder consists of a conical round shaft (1 ') with attached long-oval head (2), which is convexly curved towards the outside is (2 '). Conical knobs (3) are arranged on the underside of the long oval plate. At the point of connection between the head and the shaft there is an annular reinforcement attached (4), the radius of which is larger than the radius of the round shank.
Die axial verlaufenden Verstärkungsstege (5) laufen entlang des Schaftes bis zum Auslauf des Schaftes in der Spitze. Der Schnitt A - A zeigt den Durchmesser der Spitze und die am Mantel aufgebrachten Stabilisierungsstege.The axially extending reinforcement webs (5) run along the shaft to the end of the shaft in the tip. Section A - A shows the diameter the tip and the stabilizing bars attached to the jacket.
Der oben beschriebene Kunststoffhalter soll in drei verschiedenen Größen, abhängig von der Schraubenlänge, gefertigt werden. Durch eine entsprechende Haltevorrichtung in der zum Anbohren der Folie und des Profilbleches notwendigen Bohrmaschine ist eine Halterung für Halter und Schrauben vorgesehen, so daß der Einbau des Halters mit hohem Mechanisierungsgrad geschieht.The plastic holder described above is said to be available in three different Sizes, depending on the screw length, can be manufactured. With a corresponding Holding device in the one necessary for drilling the foil and the profile sheet Drill a holder for holder and screws is provided so that the Installation of the holder is done with a high degree of mechanization.
Die Form des Kunststoffhalters bewirkt dabei, daß - bedingt durch den Anzug der Schraube - der Kunststoffhalter flach auf der Kunststoffbahn aufliegt, durch die angeordneten Noppen kein Verrutschen auf der Oberfläche der Kunststoffbahn stattfindet und durch die ringförmige Verstärkung und die Stabilisierungsstege ein Verdrehen bzw. Abscheren des Kunststoffschaftes verhindert wird. Damit ist nicht nur hinsichtlich des Kunststoffhalters, sondern auch hinsichtlich der Verwendung dieses Kunststoffhalters beim Verlegen von Flachdächern ein enormer technischer Fortschritt gefunden.The shape of the plastic holder causes that - due to the tightening of the screw - the plastic holder flat on the plastic sheet rests, due to the arranged knobs no slipping on the surface of the Plastic web takes place and through the annular reinforcement and the stabilizing webs twisting or shearing off of the plastic shaft is prevented. So that's not only in terms of the plastic holder, but also in terms of use this plastic holder when laying flat roofs is an enormous technical one Found progress.
