Abstract

1. Grille element (1, 20) for the production of security grilles before doors, windows, cellar shafts, light domes or the like, with a grille bar (2, 14, 23, 24) and with supports (5, 9, 21, 29) which are arranged at its ends and by means of which at least one fastening element (7, 12, 34, 35) is fixable to the masonry (36, 37) or the like, characterized in that the fastening elements (7, 12, 34, 35) are fixed to the supports (5, 9, 21, 29), that the supports (5, 9, 21, 22) comprise through holders (6, 13, 27, 28, 29, 30), and that thickenings (8, 17, 31, 32, 33) are provided for the grille bar (2, 14, 23, 24) in the region of the two ends for preventing the grille bar (2, 14, 23, 24) from being pushed out of the holders (6, 13, 27, 28, 29, 30), and at least one of the thickenings (8, 17, 31, 32, 33) is to be arranged in position only after the insertion of the grille bar (2, 14, 23, 24) in the holders (6, 13, 27, 28, 29, 30).

Description

Die Erfindung betrifft ein Gitterelement für die Herstellung von Sicherheitsgittern vor Türen, Fenstern, Kellerschachten, Lichtkuppeln oder dergleichen, mit einem Gitterstab und an seinen Enden angeordneten Halterungen, die über zumindest ein Befestigungselement am Mauerwerk oder dergleichen fixierbar sind.The invention relates to a lattice element for the production of security grilles in front of doors, windows, basement shafts, skylights or the like, with a lattice rod and brackets arranged at its ends, which can be fixed to the masonry or the like via at least one fastening element.

Solche Sicherheitsgitter weisen in der Regel eine Mehrzahl von parallel und im Abstand zueinander angeordnete Gitterstäbe auf, deren Enden in Kastenprofilträgern als Halterungen eingesetzt sind. Die Kastenprofilträger sind dann mittels Schwerlastdübeln am Mauerwerk fixierbar, wobei in den Kastenprofilträgern Öffnungen vorgesehen sind, über die Werkzeuge zum Einschrauben der Schwerlastdübel eingeführt werden können. Nach der Montage werden die Öffnungen mittels Blenden verschlossen.Such security grilles generally have a plurality of grille bars arranged in parallel and at a distance from one another, the ends of which are inserted as brackets in box section girders. The box section girders can then be fixed to the masonry using heavy-duty dowels, openings being provided in the box section girders through which tools for screwing in the heavy-duty dowels can be inserted. After assembly, the openings are closed using covers.

Die vorgenannten Öffnungen haben sich als Sicherheitsschwachpunkte erwiesen, da die Blenden durchgebohrt und durch die so entstandene Bohrung Werkzeuge eingeführt werden können, mit deren Hilfe sich das komplette Sicherheitsgitter entfernen läßt.The aforementioned openings have proven to be security weak points, since the panels can be drilled through and tools can be inserted through the bore thus created, with the aid of which the entire security grille can be removed.

In der AU-P-531 175 ist ein Gitterelement zur Herstellung von Sicherheitsgittern offenbart, bei dem die freien Enden eines Gitterstabes in buchsenförmigen Halterungen sitzen, die an gegenüberliegenden Wänden mittels Schrauben befestigt sind. Auch dieses Gitterelement ist nicht sicher, da die buchsenförmigen Halterungen in dem Bereich, in dem sich der Gitterstab nicht erstreckt, durchgesägt werden können. Der Gitterstab läßt sich nämlich in den Halterungen so weit verschieben, daß er nur mit einem geringen Teil in eine der beiden Halterungen hineinragt, diese Halterung also im übrigen Teil ohne weiteres durchgesägt werden kann.AU-P-531 175 discloses a grille element for the production of security grilles, in which the free ends of a grille bar sit in socket-shaped holders which are fastened to opposite walls by means of screws. This grid element is also not safe, since the bush-shaped holders can be sawed through in the region in which the grid rod does not extend. The lattice bar can namely be moved so far in the brackets that it protrudes with only a small part into one of the two brackets, so this bracket can be sawed through in the rest of the part.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Gitterelement für Sicherheitsgitter der eingangs genannten Art so zu gestalten, daß eine Demontage praktisch unmöglich ist.The invention is therefore based on the object of designing a grille element for safety grilles of the type mentioned at the outset in such a way that disassembly is practically impossible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Befestigungselemente an den Halterungen fixierbar sind, daß die Halterungen durchgehende Aufnahmen aufweisen und daß für den Gitterstab im Bereich beider Enden Verdickungen zur Verhinderung des Herausschiebens des Gitterstabes aus den Aufnahmen vorgesehen sind, wobei zumindest eine der Verdickungen erst nach dem Einsetzen des Gitterstabes in die Aufnahmen anzubringen ist. Bei dieser Konstruktion verhindert der Gitterstab selbst ein Herausdrehen der einmal befestigten Halterungen, so daß sie praktisch nicht mehr demontiert werden können. Dabei ist von besonderem Vorteil, wenn die Befestigungselemente als Schraubdübel ausgebildet und hinter dem Gitterstab angeordnet sind.This object is achieved in that the fasteners can be fixed to the brackets, that the brackets have continuous receptacles and that thickenings are provided in the region of both ends to prevent the lattice rod from sliding out of the receptacles, at least one of the thickenings only after inserting the lattice bar into the receptacles. In this construction, the lattice rod itself prevents the brackets from being unscrewed, so that they can practically no longer be dismantled. It is particularly advantageous if the fastening elements are designed as screw dowels and are arranged behind the lattice bar.

Gemäß einem Ausführungsbeispiel der Erfindung sind die Halterungen als Rohrabschnitte mit außenstehend angebrachten Befestigungselementen ausgebildet. Diese Ausbildung ist besonders einfach.According to an embodiment of the invention, the brackets are designed as tubular sections with fastening elements attached on the outside. This training is particularly easy.

Alternativ dazu können die Halterungen auch jeweils aus einer Grundplatte mit zumindest einer darauf aufgebrachten Aufnahme für den Gitterstab bestehen.As an alternative to this, the brackets can also each consist of a base plate with at least one receptacle for the lattice bar attached to it.

Die Aufnahmen bestehen zweckmäßigerweise jeweils aus einer mit einem Durchgangsloch für den Gitterstab versehenen Halteplatte. Diese kann dann aus Stabilitätsgründen auch als Winkeleisen ausgebildet sein. Alternativ dazu können die Aufnahmen auch als Kastenprofile mit gegenüberliegenden Durchgangslöchern ausgebildet sein.The receptacles expediently each consist of a holding plate provided with a through hole for the lattice bar. This can then also be designed as an angle iron for reasons of stability. As an alternative to this, the receptacles can also be designed as box profiles with opposite through holes.

In weiterer Ausbildung der Erfindung ist vorgesehen, daß das Befestigungselement als in ein Loch in der Grundplatte eingesetzter und dort verschweißter Schraubdübel ausgebildet ist. Abweichend dazu kann das Befestigungselement auch als auf der Rückseite stehend angebrachter Schraubdübel ausgebildet sein.In a further embodiment of the invention it is provided that the fastening element is designed as a screw plug inserted into a hole in the base plate and welded there. In a departure from this, the fastening element can also be designed as a screw dowel standing on the back.

Über zumindest ein Ende des Gitterstabes ist zweckmäßigerweise jeweils eine Muffe oder ein angeschweißter Ring gestülpt, damit sie entsprechend verdickt ist. Es kann aber auch ein in dieses Ende eingesetzter Verschlußstopfen verwendet werden.A sleeve or a welded ring is expediently placed over at least one end of the lattice rod so that it is correspondingly thickened. However, a sealing plug inserted into this end can also be used.

In der Zeichnung ist die Erfindung an Hand von Ausführungsbeispielen näher veranschaulicht. Es zeigen:

  • Figur 1 einen Längsschnitt durch einen Teil eines Gitterelementes;
  • Figur 2 eine Draufsicht auf einen Teil eines anderen Gitterelementes mit Teilschnitt;
  • Figur 3 eine Seitenansicht auf das Gitterelement gemäß Figur 2;
  • Figur 4 eine Draufsicht auf ein anderes Gitterelement.
In the drawing, the invention is illustrated in more detail using exemplary embodiments. Show it:
  • 1 shows a longitudinal section through part of a grid element;
  • Figure 2 is a plan view of part of another grid element with partial section;
  • FIG. 3 shows a side view of the grid element according to FIG. 2;
  • Figure 4 is a plan view of another grid element.

In Figur 1 ist lediglich der rechtsseitige Teil eines Gitterelementes 1 dargestellt. Ein nur teilweise gezeigter Gitterstab 2 besteht aus einem Mantelrohr 3 und einem darin lose gelagerten Rundstab 4. Der Rundstab 4 macht ein Durchsägen des Gitterstabes 2 praktisch unmöglich.In Figure 1, only the right-hand part of a lattice element 1 is shown. An only partially shown lattice bar 2 consists of a casing tube 3 and a round bar 4 loosely mounted therein. The round bar 4 makes sawing through the lattice bar 2 practically impossible.

Der Gitterstab 2 sitzt in einer Halterung 5, die aus einem Rohrabschnitt 6 und einem außenseitig stehend aufgeschweißten Schwerlastdübel 7 besteht. Bei der Montage wird der Schwerlastdübel 7 durch Drehen der gesamten Halterung 5 ins Mauerwerk eingeschraubt, bis er festsitzt. Dies geschieht im Bereich beider Enden des Gitterstabes 2. Anschließend werden die Gitterstäbe 2 durch die Halterungen 5 geschoben, bis beide Enden über die Halterungen 5 vorstehen. Über eines der Enden wird dann eine Muffe 8 gestülpt, deren Durchmesser größer ist als der Innendurchmesser des Rohrabschnittes 6. Das hier nicht gezeigte Ende kann entweder durch eine weitere Muffe oder mittels einer Schloßsperre gesichert werden. Damit ist der Gitterstab 2 blockiert, kann also nicht mehr aus den Halterungen 5 herausgeschoben werden.The lattice rod 2 is seated in a holder 5, which consists of a pipe section 6 and a heavy-duty dowel 7 welded on the outside. During assembly, the heavy-duty dowel 7 is screwed into the masonry by rotating the entire bracket 5 until it is firmly seated. This takes place in the area of both ends of the lattice rod 2. The lattice rods 2 are then pushed through the holders 5 until both ends protrude beyond the holders 5. A sleeve 8 is then placed over one of the ends, the diameter of which is larger than the inner diameter of the pipe section 6. The end, not shown here, can either be through a further sleeve or by means of a Lock lock to be secured. The grating bar 2 is thus blocked and can therefore no longer be pushed out of the holders 5.

Die in den Figuren 2 und 3 dargestellte Halterung 9 besteht aus einer rechteckigen Grundplatte 10, einem darauf stehend aufgeschweißeten Winkeleisenabschnitt 11 und einem in ein Loch in der Grundplatte 10 eingesetzten und nach hinten vorstehenden Schwerlastdübel 12, dessen Kopf an der Grundplatte 10 angeschweißt ist. In einem der Schenkel des Winkeleisenabschnittes 11 ist eine Durchgangsbohrung 13 vorgesehen, die als Aufnahme für einen Gitterstab 14 dient, von dem in Figur 2 nur das rechtsseitige Ende dargestellt ist. Der Gitterstab 14 besteht hier gleichfalls aus einem Mantelrohr 1 und einem darin frei drehbar eingelegten Rundstab 16. Die Durchgangsbohrung 13 ist so angeordnet, daß der Gitterstab 14 über den Schwerlastdübel 12 verläuft.The bracket 9 shown in Figures 2 and 3 consists of a rectangular base plate 10, an angle iron section 11 welded thereon and a heavy-duty dowel 12 inserted into a hole in the base plate 10 and projecting rearwards, the head of which is welded to the base plate 10. In one of the legs of the angle iron section 11 a through hole 13 is provided which serves as a receptacle for a lattice bar 14, of which only the right-hand end is shown in FIG. 2. The lattice bar 14 here also consists of a casing tube 1 and a round bar 16 inserted freely rotatably therein. The through hole 13 is arranged such that the lattice bar 14 extends over the heavy-duty dowel 12.

Über das Ende des Gitterstabes 14 bzw. des Mantelrohrs 15 ist eine Muffe 17 gestülpt, die ein Herausrutschen des Gitterstabes 14 aus der Durchgangsbohrung 13 verhindertA sleeve 17 is placed over the end of the grating bar 14 or the casing tube 15, which prevents the grating bar 14 from slipping out of the through bore 13

Bei der Montage wird ähnlich wie bei dem Gitterelement 1 nach Figur 1 verfahren, d. h. die gesamte Halterung 9 wird zum Einschrauben des Schwerlastdübels 12 gedreht, his die Halterung 9 festsitzt und die Durchgangsbohrung 13 in der gewünschten Stellung steht. Anschließend wird der Gitterstab 14 durch die Durchgangsbohrung 13 und natürlich auch durch die Durchgangsbohrung der Halterung auf der anderen Seite geschoben. Anschließend wird das andere Ende des Gitterstabes 14 mit einer weiteren Muffe oder einer Schloßsperre gesichert.During assembly, the procedure is similar to that of the lattice element 1 according to FIG. 1; H. the entire bracket 9 is rotated to screw in the heavy-duty dowel 12, the bracket 9 is firmly seated and the through hole 13 is in the desired position. Then the lattice rod 14 is pushed through the through hole 13 and of course also through the through hole of the holder on the other side. The other end of the lattice bar 14 is then secured with a further sleeve or a lock.

Figur 4 zeigt ein Gitterelement 20 mit zwei Halterungen 21, 22, in denen zwei Gitterstäbe 23, 24 gehalten sind. Von diesen Gitterstäben 23, 24 ist der mittlere Gitterstab 24 verkürzt und der linke Gitterstab 23 nur teilweise dargestellt.FIG. 4 shows a lattice element 20 with two brackets 21, 22 in which two lattice bars 23, 24 are held. Of these bars 23, 24, the middle bar 24 is shortened and the left bar 23 is only partially shown.

Die beiden Halterungen 21, 22 bestehen jeweils aus einem oben und unten offenen Kastenprofil 25, 26, wobei die Kastenprofile 25, 26 jeweils zwei gegenüberliegende Durchgangslöcher 27, 28 bzw. 29, 30 aufweisen. In das in dieser Ansicht rechte Kastenprofil 26 ist der Gitterstab 24 so eingeschoben, daß er durch beide Durchgangslöcher 29, 30 hindurchgeht. In sein offenes Ende ist ein Verschlußstopfen 31 eingesetzt, dessen nach außen vorstehendes Ende sich kegelförmig verbreitert, so daß der Gitterstab 24 nicht mehr in Richtung nach links aus der Halterung 22 herausgezogen werden kann.The two brackets 21, 22 each consist of a box profile 25, 26 open at the top and bottom, the box profiles 25, 26 each having two opposite through holes 27, 28 and 29, 30, respectively. In the right box profile 26 in this view, the grating bar 24 is inserted so that it passes through both through holes 29, 30. In its open end, a plug 31 is inserted, the outwardly projecting end of which widens conically, so that the grating bar 24 can no longer be pulled out of the holder 22 in the direction to the left.

Das rechte Ende des Gitterstabes 24 ist nur durch ein Durchgangsloch 28 des Kastenprofils 25 gesteckt und durch einen Verschlußstopfen 32 gesichert. Entsprechend ist der linke Gitterstab 23 in das Durchgangsloch 27 eingesteckt und ebenfalls durch einen Verschlußstopfen 33 fixiert. Auf diese Weise dient die Halterung 21 zur Aufnahme von zwei koaxial zueinander verlaufenden Gitterstäben 23, 24, wobei das Einführen der Verschlußstopfen 32, 33 durch die Öffnungen an der Ober- bzw. Unterseite des Kastenprofils 25 geschehen kann.The right end of the lattice rod 24 is only inserted through a through hole 28 of the box section 25 and secured by a plug 32. Correspondingly, the left lattice bar 23 is inserted into the through hole 27 and also fixed by a sealing plug 33. In this way, the holder 21 serves to receive two coaxial bars 23, 24, the insertion of the plugs 32, 33 can be done through the openings on the top and bottom of the box section 25.

Die Halterungen 21, 22 sind mittels Schwerlastdübel 34, 35 an Mauerstücken 36, 37 befestigt. Die Schwerlastdübel 34, 35 sind durch entsprechende Öffnungen in den Kastenprofilen 25, 26 gesteckt und mit ihnen verschweißt. Die Befestigung der Kastenprofile 25, 26 kann also nur so geschehen, daß jeweils das gesamte Kastenprofil 25, 26 zusammen mit den zugehörigen Schwerlastdübeln 34, 35 in eine entsprechende Öffnung in den Mauerstücken 36, 37 eingedreht werden muß. In der Endstellung und bei eingesetzten Gitterstäben 23, 24 ist dann ein Verdrehen der Kastenprofile 25, 26 und damit ein Lösen von den Mauerstücken 36, 37 nicht mehr möglich.The brackets 21, 22 are attached to wall pieces 36, 37 by means of heavy-duty dowels 34, 35. The heavy-duty dowels 34, 35 are inserted through corresponding openings in the box profiles 25, 26 and welded to them. The attachment of the box profiles 25, 26 can only be done so that the entire box profile 25, 26 together with the associated heavy-duty dowels 34, 35 must be screwed into a corresponding opening in the wall sections 36, 37. In the end position and when the bars 23, 24 are inserted, it is then no longer possible to twist the box sections 25, 26 and thus to detach them from the wall sections 36, 37.

Ein Sicherheitsgitter wird durch parallele Anordnung mehrerer der dargestellten Gitterelemente gebildet.A security grille is formed by arranging several of the grille elements shown in parallel.
