Description

Vorrichtung zur Befestigung eines Gitterrahmens Device for fastening a lattice frame
Die Erfindung betrifft eine Vorrichtung zur Befestigung eines Gitterrahmens an der Leibung einer Mauerwerksöff¬ nung mit mehreren Mauerankern, die jeweils einen in einer Ankerbohrung fixierten Verankerungsteil mit einem einschraubbaren Ankerbolzen aufweisen, dessen Kopf an einem am Gitterrahmen befindlichen Widerlager abge¬ stützt ist und dessen Schaft von einer Schutzhülse um¬ geben ist, die einerseits in eine dem Gitterrahmen zu¬ geordnete Ausnehmung und andererseits in eine die An¬ kerbohrung umgebende Ausnehmung ragt.The invention relates to a device for fastening a lattice frame to the reveal of a masonry opening with a plurality of wall anchors, each of which has an anchoring part fixed in an anchor hole with a screw-in anchor bolt, the head of which is supported on an abutment located on the lattice frame and the shaft of which is surrounded by a protective sleeve which, on the one hand, projects into a recess assigned to the lattice frame and, on the other hand, into a recess surrounding the anchor hole.
Eine Vorrichtung der eingangs genannten Art ist aus der DE AI 34 12 608 bekannt, in der die Befestigung eines verzinkten Gitters in Fensterleibungen mit angesetzten Wandankern beschrieben ist.A device of the type mentioned is known from DE AI 34 12 608, in which the attachment of a galvanized grating in window reveals with attached wall anchors is described.
Diese Vorrichtung besteht aus einer am Gitterrahmen befestigten, beidseitig offenen Ankeraufnahme- und Git- terrah entraghülse, durch die der Ankerbolzen gesteckt und in der Ankerbohrung verschraubt ist. Zur Fixierung des Ankerbolzens am Gitterrahmen weist die Gitterrah- mentraghülse in ihrem Inneren ein Widerlager auf, durch welches der Anker hindurchgreift.This device consists of an anchor receptacle and a mesh support sleeve attached to the lattice frame and open on both sides, through which the anchor bolt is inserted and is screwed into the anchor hole. To fix the anchor bolt to the lattice frame, the lattice frame support sleeve has an abutment in its interior, through which the anchor reaches.
Das Gitter ist auf diese Weise ohne Schweißarbeiten mit einem seitlichen Abstand zur Leibung in den Mauerwerks- durchbruch einsetzbar, wobei zur Sicherung des Anker¬ bolzens gegen Durchsägen in dem Zwischenraum zwischen der Leibung und dem Gitterrahmen eine auf dem Ankerbol¬ zen frei drehbare Schutzhülse vorgesehen ist. Die Schutzhülse ragt teilweise in die durch die Gitterrah- mentraghülse gebildete Ausrieh ung und teilsweise in die Ausnehmung in der Ankerbohrung. Dadurch soll verhindert werden, daß entlang der Leibung oder entlang des Git¬ terrahmens an der Schutzhülse vorbei der Ankerbolzen angegriffen werden kann.In this way, the grating can be inserted into the masonry opening without any welding work, with a lateral distance from the reveal, a protective sleeve which can be freely rotated on the anchor bolt being provided to secure the anchor bolt against sawing through in the space between the reveal and the lattice frame . The protective sleeve projects partially into the recess formed by the lattice frame support sleeve and partially into the recess in the anchor hole. This is to prevent the anchor bolt from being attacked past the protective sleeve along the reveal or along the frame.
Trotz einer Vereinfachung der Montage und einer Erhö¬ hung der Sicherheit gegen Durchsägen der Ankerbolzen hat die eingangs genannte Vorrichtung den Nachteil, daß das Gitter nur an den Ankerbolzen und im wesentlichen frei hängend, labil in der Mauerwerksöffnung befestigt ist.Despite a simplification of the assembly and an increase in security against sawing through through the anchor bolts, the device mentioned at the outset has the disadvantage that the grille is only unstably attached to the anchor bolts and is essentially freely suspended and unstable in the masonry opening.
Die Mauerwerksöffnungen weisen in der Regel Maßdiffe¬ renzen auf, die durch die Ankerbolzen ausgeglichen wer- den müssen. Dadurch ist beim Einbau des Gitters ein hoher Aufwand für das Justieren und das Ausrichten des Gitters erforderlich. Weiterhin sind die Haltbarkeit und auch die Sicherheit des Gitters durch die Ankerbol¬ zen begrenzt, die eine Schwachstelle darstellen. Bei großen, auf das Gitter einwirkenden Querkräften halten die Ankerbolzen nicht stand, so daß das Gitter verhält- nismäßig leicht durch rohe Gewalt entfernbar ist. Eben¬ so kann nicht ausgeschlossen werden, daß die drehbare Schutzhülse festgeklemmt und dadurch die Schutzhülse und der darunter befindliche Ankerbolzen durchgesägt werden können.The masonry openings generally have dimensional differences which have to be compensated for by the anchor bolts. As a result, a great deal of effort is required to adjust and align the grille when installing the grille. Furthermore, the durability and also the safety of the grating are limited by the anchor bolts, which represent a weak point. In the case of large transverse forces acting on the grating, the anchor bolts do not withstand, so that the grating behaves is easily removed by brute force. Likewise, it cannot be ruled out that the rotatable protective sleeve can be clamped in place, thereby sawing through the protective sleeve and the anchor bolt located underneath.
Aufgabe der Erfindung ist es, die Vorrichtung der ein- gangs genannten Art dahingehend weiterzubilden, daß die Sicherheit erhöht, der Ausgleich der Maßdifferenzen erleichtert und die Montage vereinfacht werden können.The object of the invention is to further develop the device of the type mentioned at the outset in such a way that safety is increased, the dimensional differences are made easier and the assembly can be simplified.
Zur Lösung dieser Aufgabe schlägt die Erfindung ausge- hend von der Vorrichtung der eingangs genannten Art vor, daß die Schutzhülse aus gehärtetem Material be¬ steht, die sich gitterseitig axial am Gitterrahmen ab¬ stützt und in der Leibung mit Klebemörtel in die die Ankerbohrung umgebende Ausnehmung einklebbar ist.To achieve this object, the invention proposes, starting from the device of the type mentioned at the outset, that the protective sleeve consists of hardened material, which is axially supported on the grid side on the grid frame and in the reveal with adhesive mortar in the recess surrounding the anchor hole can be glued in.
Mit der als gehärtetes Drehteil ausgebildeten Schutz¬ hülse ist ein hoher Sicherheitsgrad bei vergleichsweise geringem Montageaufwand erreichbar, da ein Zersägen mit Sicherheit augeschlossen werden kann. Bestehende Maß- differenzen in den Mauerwerksöffnungen lassen sich mit der erfindungsgemäßen Vorrichtung darüber hinaus durch Verändern der Tiefe der Ausnehmungen in den Ankerboh¬ rungen in Verbindung mit verschieden lang ausgebildeten Schutzhülsen auf einfache Weise ausgleichen. Zu tief eingebrachte Ausnehmungen können auf einfache Weise durch Klebemörtel verfüllt werden, wobei gewährleistet ist, daß kein Spalt zwischen der Leibung oder dem Git¬ terrahmen und der Schutzhülse entsteht. Durch die in die in der Leibung und dem Gitterrahmen befindlichen Ausnehmungen einlegbaren Schutzhülsen las- sen sich darüber hinaus die Gitter während der Montage an den Schutzhülsen justieren, wodurch eine einfachere und leichtere Montage der Gitter möglich ist.With the protective sleeve designed as a hardened turned part, a high degree of security can be achieved with comparatively little installation effort, since sawing can be excluded with certainty. Existing dimensional differences in the masonry openings can also be easily compensated for with the device according to the invention by changing the depth of the recesses in the anchor holes in conjunction with protective sleeves of different lengths. Recesses made too deep can be filled in easily with adhesive mortar, whereby it is ensured that there is no gap between the reveal or the frame and the protective sleeve. Thanks to the protective sleeves that can be inserted into the recesses in the reveal and the lattice frame, the grilles can also be adjusted during assembly on the protective sleeves, which makes the grille easier and easier to assemble.
Von Vorteil ist es des weiteren, wenn die Schutzhülsen sowohl außen, als auch innen eine gehärtete Oberfläche aufweisen, womit in Verbindung mit einem gehärteten Schutzgitter ein hoher Sicherheitsgrad erzielt wird.It is also advantageous if the protective sleeves have a hardened surface both on the outside and on the inside, with which a high degree of security is achieved in connection with a hardened protective grille.
In einer Ausgestaltung der Erfindung ist vorgesehen, daß zwischen der Schutzhülse und dem Gewindebolzen ein mit Klebemörtel beaufschagbarer Ringraum vorhanden ist, der gitterseitig von einem mit der Schutzhülse verbun¬ denen, auf dem Außenumfang des Gewindebolzens gleiten¬ den Kragen verschlossen und leibungsseitig offen ist. Der Kragen bewirkt in vorteilhafter Weise, daß bei der Füllung des Ringraumes zwischen dem Gewindebolzen und der Schutzhülse mit dem Klebemörtel dieser einen Druck auf die Fläche des Kragens ausübt, wodurch die Schutz¬ hülse fest in die Ausnehmung der Bohrung im Gitterrah- men gedrückt wird. Somit ist gewährleistet, daß einer¬ seits kein Spalt zwischen der Schutzhülse und der Lei¬ bung und dem Gitterrahmen entsteht. Andererseits wird das Gitter an beiden Seiten der Mauerwerksöffnung in die Leibung gepreßt, wodurch sich eine stabile Befesti- gung des Gitters insgesamt erzielen läßt.In one embodiment of the invention it is provided that between the protective sleeve and the threaded bolt there is an annular space which can be loaded with adhesive mortar and which is closed on the grid side by a collar which is connected to the protective sleeve and slides on the outer circumference of the threaded bolt and is open on the reveal side. The collar advantageously has the effect that when the annular space between the threaded bolt and the protective sleeve is filled with the adhesive mortar, this exerts pressure on the surface of the collar, as a result of which the protective sleeve is pressed firmly into the recess in the bore in the lattice frame. This ensures that, on the one hand, there is no gap between the protective sleeve and the cable and the lattice frame. On the other hand, the grille is pressed into the reveal on both sides of the masonry opening, as a result of which a stable fastening of the grille as a whole can be achieved.
Weiterhin schlägt die Erfindung vor, daß die Schutzhül¬ se wenigstens eine in deren Wandung angeordnete Durch- gangsbohrung aufweist. Diese Durchgangsbohrung kann radial oder in einem Winkel zur Achse der Schutzhülse angeordnet sein. Die Durchgangsbohrung ist vorgesehen, um in einfacher Weise mittels einer entsprechenden Vorrichtung zum Verpressen des Klebemörtels denselben in den Ringraum innerhalb der Schutzhülse und die ande¬ ren zwangsläufig vorhandenen Zwischenräume einzubrin¬ gen. Damit werden einerseits alle Hohlräume nach der Montage verfüllt und die Verankerung des Gitters wird verfestigt. Andererseits wird dadurch die Schutzhülse, wie bereits erwähnt, mittels des Klebemörtels fest gegen den Gitterrahmen verschoben.Furthermore, the invention proposes that the protective sleeve has at least one through hole arranged in its wall. This through hole can be arranged radially or at an angle to the axis of the protective sleeve. The through hole is provided in order in a simple manner to introduce the same into the annular space inside the protective sleeve and the other gaps which are necessarily present by means of a corresponding device for pressing the adhesive mortar. On the one hand, all cavities are filled after assembly and the anchoring of the grating is solidified. On the other hand, as already mentioned, the protective sleeve is thereby moved firmly against the lattice frame by means of the adhesive mortar.
Die Durchgangsbohrung befindet sich vorteilhaft im Bereich des Kragens der Schutzhülse, wodurch eine gün- stige Handhabung der Vorrichtung zum Verpressen des Füllmörtels aufgrund des Gitterabstandes zur Leibung möglich ist.The through hole is advantageously located in the region of the collar of the protective sleeve, as a result of which the device for pressing the filling mortar can be handled inexpensively due to the grid spacing from the reveal.
Zweckmäßig ist es darüber hinaus, wenn der Gewindebol- zen in eine Gewindehülse eingreift, die axial am Veran¬ kerungsteil befestigt ist. Die Gewindehülse läßt sich in vorteilhafter Weise vor der Montage des Verankerungs- teiles mit diesem verbinden. Anschließend kann das komplettierte Verankerungsteil mit nach außen gerichte- ter Gewindehülse in die entsprechend der Bohrungen im Gitterrahmen in der Leibung eingebrachten Ankerbohrun¬ gen befestigt werden, wobei die jeweilige Ausnehmung frei von Klebemörtel bleibt. Der Abstand der sich in den Leibungen gegenüberliegend angeordneten Gewindehül- sen liegt dabei unter der Abmessung des Gitters. Da¬ durch tritt insbesonder der Vorteil auf, daß die Schutzhülsen ohne weitere Hilfsmaßnahmen auf die Gewin- dehülsen bis in die Ausnehmung hinein aufgelegt und dasIt is also expedient if the threaded bolt engages in a threaded sleeve which is fastened axially to the anchoring part. The threaded sleeve can advantageously be connected to the anchoring part before it is installed. The completed anchoring part can then be fastened with the threaded sleeve facing outward into the anchor holes made in the reveal according to the bores in the lattice frame, the respective recess remaining free of adhesive mortar. The distance between the threaded sleeves located opposite each other in the reveal is below the dimension of the grid. As a result, there is the particular advantage that the protective sleeves are placed on the threaded sleeves and into the recess without any additional measures, and that
Gitter zwischen die Gewindehülsen gebracht werden kann. Das Gitter wird anschließend nur noch entsprechend der Anzahl der Gewindebolzen von der Gitterseite her ver¬ schraubt. Die Schutzhülse liegt zu diesem Zeitpunkt noch lose auf dem Außenumfang des Gewindebolzens zwischen der Leibung und dem Gitterrahmen, von wo es anschließend mit den beschriebenen Mitteln und Maßnah¬ men in seine endgültige Position gebracht wird.Grid can be placed between the threaded sleeves. The grid is then screwed on from the grid side only in accordance with the number of threaded bolts. At this time, the protective sleeve still lies loosely on the outer circumference of the threaded bolt between the reveal and the lattice frame, from where it is then brought into its final position using the means and measures described.
Letztlich ist vorgesehen, daß die Werkzeugöffnung am Kopf des Gewindebolzens und/oder die Senkung nach der Montage verschließbar ist. Als Verschluß dient entweder ein Dübel, der in die Werkzeugöffnung eingeschlagen und vernietet wird oder die Senkung wird vernietet. DieseUltimately, it is provided that the tool opening at the head of the threaded bolt and / or the countersink can be closed after assembly. Either a dowel, which is hammered into the tool opening and riveted, or the countersink is riveted serves as the closure. This
Maßnahme hat den Vorteil, daß der Gewindebolzen nicht mehr gelöst werden kann.Measure has the advantage that the threaded bolt can no longer be loosened.
Ein Ausführungsbeispiel der Erfindung wird im folgenden anhand einer Zeichnung näher erläutert:An embodiment of the invention is explained in more detail below with reference to a drawing:
In der zugehörigen Zeichnung ist der Schnitt durch eine Vorrichtung zur Befestigung eines Gitterrahmens darge¬ stellt. Wegen der symmetrischen Anordnung aller Teile beschränkt sich die Zeichnung zur besseren Darstellung nur auf einen Halbschnitt entang der Symmetrieachse.In the accompanying drawing, the section through a device for fastening a lattice frame is shown. Because of the symmetrical arrangement of all parts, the drawing is limited to a half-section along the axis of symmetry for better illustration.
Die Vorrichtung zur Befestigung eines Gitterrahmens an der Leibung einer Mauerwerksöffnung ist im wesentlichen an einem Gitter 1 mit einem Gitterrahmen 2 vorgesehen, wobei im Gitterrahmen 2 eine Bohrung 3 mit einer Sen¬ kung 4 angeordnet ist. In der Bohrung 3 ist ein Gewin¬ debolzen 5 mit einem Kopf 6 vorgesehen, der mit einer Schutzhülse 7 mit einem Kragen 8 umgeben ist. Der Ge¬ windebolzen 5 ist über eine Gewindehülse 9 innerhalb der Leibung 10 mit einem Verankerungsteil 11 verbunden, das mittels einer Siebhülse 12 in einer Ankerbohrung 13 mittels Klebemörtel 14 verankert ist.The device for fastening a lattice frame to the reveal of a masonry opening is essentially provided on a lattice 1 with a lattice frame 2, a bore 3 with a depression 4 being arranged in the lattice frame 2. In the bore 3, a threaded bolt 5 is provided with a head 6, which is surrounded by a protective sleeve 7 with a collar 8. The threaded bolt 5 is connected via a threaded sleeve 9 within the reveal 10 to an anchoring part 11, which is anchored by means of a sieve sleeve 12 in an anchor hole 13 by means of adhesive mortar 14.
Gemäß der Zeichnung besteht das Gitter 1 im wesentli¬ chen aus einem aus Flachmaterial bestehenden flächen- förmigen Gitterrahmen 2 mit einer Anzahl von in den Seitenteilen des Gitterrahmens 2 eingeschweißten Quer- streben 2.2. In den Querstreben 2.2 sind abstandsweise senkrecht Gitterstäbe (nicht dargestellt) eingesetzt, die an den oberen und unteren Streben des Gitterrahmens 2 ebenfalls verschweißt sind.According to the drawing, the lattice 1 essentially consists of a flat lattice frame 2 made of flat material with a number of transverse struts 2.2 welded into the side parts of the lattice frame 2. Lattice bars (not shown) are inserted vertically in the cross struts 2.2, which are also welded to the upper and lower struts of the lattice frame 2.
An den vorgesehenen Verarikerungsstellen sind in den Seitenteilen des Gitterrahmens 2 Bohrungen 3 in der Richtung zur Fläche des Gitters 1 eingebracht, die git- terseitig jeweils die Senkung 4 für den Kopf 6 des Gewindebolzens 5 aufweisen. An der Senkung 4 gegenüber- liegenden Seite weisen die Durchgangsbohrungen 3 eine Ausnehmung 2.1 auf, die der Schutzhülse 7 angepaßt ist.At the intended processing points, bores 3 are made in the side parts of the lattice frame 2 in the direction of the surface of the lattice 1, each of which has the countersink 4 for the head 6 of the threaded bolt 5 on the lattice side. On the countersink 4 opposite side, the through holes 3 have a recess 2.1, which is adapted to the protective sleeve 7.
Das Gitter 1 ist vorzugsweise ganzflächig gehärtet, woduch in Verbindung mit der erfindungsgemäßen Vorrich- tung ein hoher Sicherheitsgrad erreicht wird.The grating 1 is preferably hardened over the entire surface, whereby a high degree of security is achieved in connection with the device according to the invention.
Zur Abstandshalterung zwischen dem Gitter 1' und der Leibung 10 sowie zum sicheren Schutz des Verankerungs¬ teiles 11 mit seinen Befestigungsmitteln 5; 9 und zur Erhöhung der Stabilität der Verankerung des Gitters 1 ist je Ankerbolzen 11 die Schutzhülse 7 vorgesehen. Die Schutzhuse 7 ist als Drehteil mit einem Ringraum 7.1 ausgebildet und ist teilweise in einer Ausnehmung 13.1 der Ankerbohrung 13 in der Leibung 10 und teilwei- se in der Auneh ung 2.1 des Gitterrahmens 2 eingesetzt. Die Distanzhülse 7 kann entsprechend der vorgegebenen zu vergitternden Mauerwerksöffnungen unterschiedlich lang ausgebildet sein, so daß Bauwerksdifferenzen ausgeglichen werden können, ohne daß der Gewindebolzen 5 an einer Stelle zwischen der Leibung 10 und dem Git¬ terrahmen 2 freiliegt.For spacing between the grid 1 'and the reveal 10 and for the safe protection of the anchoring part 11 with its fastening means 5; 9 and to increase the stability of the anchoring of the grating 1, the protective sleeve 7 is provided for each anchor bolt 11. The protective cover 7 is designed as a turned part with an annular space 7.1 and is partly inserted into a recess 13.1 in the anchor hole 13 in the reveal 10 and partly in the recess 2.1 of the lattice frame 2. The spacer sleeve 7 can correspond to the given one to be constructed of grating masonry openings of different lengths, so that building differences can be compensated without the threaded bolt 5 being exposed at a point between the reveal 10 and the frame 2.
Der Durchmesser der Schutzhülse 7 ist in Abhängigkeit 1 vom Gewindebolzen 5 und der zu verankernden Gittergröße entsprechend ausgebildet. An der dem Gitterrahmen 2 zugewandten Seite der Schutzhülse 7 ist deren Ringraum 7.1 mit dem Kragen 8 versehen, der als Druckfläche zum Verschieben der Schutzhülse 7 gegen den Gitterrahmen *5 2 beim Füllen der Hohlräume mit dem Klebemörtel 14 dient. Der Kragen 8 ist so ausgebildet, daß die Schutz¬ hülse 7 möglichst eng am Gewindebolzen 5 anliegend, an dessen Außendurchmesser verchiebbar ist. Zur Handha¬ bung der Schutzhülse 7 und als Einfüllöffnung für den 0 Klebemörtel 14 ist eine Durchgangsborung 8.1 in der Wandung der Distanzhülse 7 eingebracht, die radial oder einem anderen Winkel zur Achse der Schutzhülse 7 an¬ geordnet sein kann.The diameter of the protective sleeve 7 is designed as a function of 1 depending on the threaded bolt 5 and the grid size to be anchored. On the side of the protective sleeve 7 facing the lattice frame 2, its annular space 7.1 is provided with the collar 8, which serves as a pressure surface for displacing the protective sleeve 7 against the lattice frame * 5 2 when the cavities are filled with the adhesive mortar 14. The collar 8 is designed in such a way that the protective sleeve 7 lies as closely as possible against the threaded bolt 5, on the outside diameter of which it can be displaced. For the handling of the protective sleeve 7 and as a filling opening for the adhesive mortar 14, a through bore 8.1 is made in the wall of the spacer sleeve 7, which can be arranged radially or at another angle to the axis of the protective sleeve 7.
5 Das Verankerungsteil 11 kann beispielsweise als Gewin¬ destange ausgebildet sein und weist an seinem zeich¬ nungsgemäß rechts liegenden Ende die Gewindehülse 9 auf, die mit dem Verankerungsteil 11 verschweißt ist. Die Länge des Verankerungsteiles 11 ist entsprechend 0 der Tiefe der Ankerbohrung 13 ausgebildet und so in dieser eingesetzt, daß die Gewindehülse 9 um einen Be¬ trag über die Fläche der Leibung 10 übersteht. Auf die überstehende Gewindehülse 9 ist die Schutzhülse 7 ge¬ steckt, die teilweise in der Ausnehmung 13.1 liegt,5 The anchoring part 11 can be designed, for example, as a threaded rod and has at its end lying on the right in the drawing the threaded sleeve 9 which is welded to the anchoring part 11. The length of the anchoring part 11 is designed to correspond to the depth of the anchor hole 13 and is inserted into it in such a way that the threaded sleeve 9 protrudes over the surface of the reveal 10 by an amount. The protective sleeve 7, which partially lies in the recess 13.1, is plugged onto the protruding threaded sleeve 9,
3 jedoch im Montagezustand des Gitters 1 sowohl nach der einen, als auch nach der anderen Seite ein Verschieben der Schutzhülse 7 gestattet. Das Gitter 1 wird schließlich mittels der für die Git¬ teroberfläche erforderlichen Anzahl Gewindebolzen 5 mit den Gewindehülsen 9 und den aufgesteckten Schutzhülsen 7 von der Gitterseite her gegen die Leibungen 10 der Mauerwerköffnung unter Einhaltung eines gleichen Ab- standes des Gitterrahmens 2 zu den Leibungen 10 ver¬ schraubt. Anschließend wird durch die jeweilige Durch¬ gangsbohrung 8.1 Schutzhülsen 7 der Klebemörtel 14 in den Ringraum 7.1 eingepreßt, wodurch die Schutzhülse 7 gegen den Gitterrahmen bei gleichzeitiger Ausfüllung der Ausnehmung 13.1 und des Ringraumes 7.1 gedrückt wird.3, however, in the assembled state of the grille 1, the protective sleeve 7 can be moved both on one side and on the other side. The lattice 1 is finally ver by means of the number of threaded bolts 5 with the threaded sleeves 9 and the attached protective sleeves 7 required for the lattice surface from the lattice side against the reveal 10 of the masonry opening while maintaining an equal distance from the lattice frame 2 to the reveal 10 ¬ screws. Then protective sleeves 7 of the adhesive mortar 14 are pressed into the annular space 7.1 through the respective through bore 8.1, whereby the protective sleeve 7 is pressed against the lattice frame while simultaneously filling the recess 13.1 and the annular space 7.1.
Abschließend können die Werkzeugöffnungen der Gewinde¬ bolzen 5 mittels eines Dübels 6.2 verschlossen werden. Ebenso kann diese Öffnung oder die Senkung 4 vernietet werden, um ein Lösen der Gewindebolzen 5 mit Sicherheit auszuschließen.Finally, the tool openings of the threaded bolts 5 can be closed using a dowel 6.2. Likewise, this opening or the countersink 4 can be riveted in order to rule out the loosening of the threaded bolts 5 with certainty.
Ein in einer Mauerwerksöffnung mit der erfindungsge¬ mäßen Vorrichtung eingesetztes Gitter ist praktisch nicht überwindbar. Einerseits ist ein Durchsägen der Ankerbolzen im Zwischenraum zwischen der Leibung und dem Rahmen wegen der gehärteten Distanzhülsen nicht möglich. Andererseits sind die Ankerbolzen durch die Ausnehmungen in der Leibung und dem Gitterrahmen nicht erreichbar, ohne das Mauerwerk oder den Gitterrahmen zu zerstören. Darüber hinaus wird das Abscheren der Anker¬ bolzen an den bisherigen Schwachstellen, durch die an diesen Stellen vorgesehenen und eingelassenen Schutz¬ hülsen mit Sicherheit ausgeschlossen. A grid used in a masonry opening with the device according to the invention is practically impossible to overcome. On the one hand, sawing through through the anchor bolts in the space between the reveal and the frame is not possible because of the hardened spacer sleeves. On the other hand, the anchor bolts cannot be reached through the recesses in the reveal and the lattice frame without destroying the masonry or the lattice frame. In addition, the shear-off of the anchor bolts at the previous weak points is reliably excluded by the protective sleeves provided and embedded in these points.
