Definitions
- the invention relates to a grid rod for raised floors, consisting of footrests, which have head plates for connecting the grid rods made of square tubes, as well as floor plates laid on the grid rods, the head plates of the footrests on their circumference with cross-shaped pairs of slots and holes for Inclusion of the grid rod ends or of tabs, thorns or fastening screws are provided on the grid rod ends.
- the head plates of the footrests have pairs of cross-shaped slots on their circumference, into which the side walls at the ends of each grid rod are inserted from above.
- One of the two other walls of the grid rod is provided with corresponding recesses at its ends in order to enable the ends of the side walls of the grid rod to be inserted into the slots in the head plates of the footrests.
- tabs projecting inward are provided in one bar type and, in another bar type, bores are arranged instead of these tabs for the passage of fastening screws.
- the grid bars with the tabs at their ends are inserted practically loosely into the supporting substructure, while the other Grid type is screwed to the head plates of the footrests.
- the load-bearing substructure is reinforced even better.
- the two stiffening variants for the load-bearing substructure of the raised floor have so far disadvantageously required the production and storage of two different types of grid bars.
- the above-mentioned cutouts in the locking bars result in sharp edges which form a risk of injury to the fitters during assembly of the raised floor and also during subsequent installation work.
- the invention has for its object to eliminate the above shortcomings and to create a grid rod for raised floors, which can either be inserted loosely into the supporting substructure of the raised floors or can also be screwed tightly thereto.
- Such a grid bar can advantageously, depending on its selected installation version, be loosely inserted into the load-bearing substructure or also firmly with it be screwed.
- the same type of grid bar can therefore be used for both installation variants, which simplifies the manufacture and storage of these bars. If it turns out after installation of the grid bars that the raised floor or its supporting substructure z. B. must be stiffened more in sections, you only need to simply turn the grid bars in the relevant floor section and screw them to the head plates of the footrests. The exchange action of grid bars that was previously required in such situations is no longer necessary. Yet another advantage of the grid rod according to the invention is that it has no sharp-edged ends that could pose a risk of injury.
- the optional arrangement of the grid rod in one or the other installation position in the load-bearing substructure of the raised floor is made possible in that the slanted side walls of the grid rod can be inserted into the slots on the head plates of the previously mounted footrests in each installation position. Either the tabs, mandrels or the like are brought into engagement with the holes in the head plates of the footrests or the fastening screws passed through the holes in the rod ends are screwed into the holes in the head plates. Self-tapping screws are used for this purpose.
- the ends of the side walls of the grid bar are beveled at an angle of approximately 60 ° with respect to the other two bar walls.

Abstract
Description
Die Erfindung bezieht sich auf einen Rasterstab für Doppelböden, bestehend aus Fußstützen, welche Kopfplatten zum Anschluß der aus Vierkantrohren hergestellten Rasterstäbe aufweisen, sowie aus auf den Rasterstäben verlegten Bodenplatten, wobei die Kopfplatten der Fußstützen an ihrem Umfang mit kreuzförmig angeordneten Paaren von Schlitzen und Bohrungen zur Aufnahme der Rasterstabenden bzw. von Laschen, Dornen oder Befestigungsschrauben an den Rasterstabenden versehen sind.The invention relates to a grid rod for raised floors, consisting of footrests, which have head plates for connecting the grid rods made of square tubes, as well as floor plates laid on the grid rods, the head plates of the footrests on their circumference with cross-shaped pairs of slots and holes for Inclusion of the grid rod ends or of tabs, thorns or fastening screws are provided on the grid rod ends.
Es ist bekannt, zur Aussteifung der tragenden Unterkonstruktion von Doppelböden zwischen den Kopfplatten der Fußstützen Rasterstäbe anzuordnen, auf welchen dann die Bodenplatten verlegt werden. Die Kopfplatten der Fußstützen weisen zu diesem Zweck an ihrem Umfang Paare von kreuzförmig angeordneten Schlitzen auf, in welche die Seitenwände an den Enden jedes Rasterstabes von oben eingesteckt werden. Eine der zwei anderen Wände des Rasterstabes ist an ihren Enden mit entsprechenden Aussparungen versehen, um das Einstecken der Enden der Seitenwände des Rasterstabes in die Schlitze in den Kopfplatten der Fußstützen zu ermöglichen. An den diesen Aussparungen gegenüberliegenden Wand-Endabschnitten der Rasterstäbe sind bei einem Stabtyp nach innen ragende Laschen vorgesehen und bei einem anderen Stabtyp sind anstelle dieser Laschen Bohrungen für die Durchführung von Befestigungsschrauben angeordnet. Die Rasterstäbe mit den Laschen an ihren Enden werden praktisch lose in die tragende Unterkonstruktion eingelegt, während der andere Rasterstabtyp mit den Kopfplatten der Fußstützen verschraubt wird. In dem zuletzt genannten Fall erfährt die tragende Unterkonstruktion eine noch bessere Versteifung. Die zwei Aussteifungsvarianten für die tragende Unterkonstruktion des Doppelbodens erfordern bisher jedoch in nachteiliger Weise die Herstellung und Lagerhaltung von zwei unterschiedlichen Rasterstabtypen. Hinzukommt, daß durch die oben erwähnten Aussparungen in den Rastestabenden scharfe Kanten entstehen, die bei der Montage des Doppelbodens und auch bei nachträglichen Installationsarbeiten eine Verletzungsgefahr für die Monteure bilden.To reinforce the load-bearing substructure of raised floors, it is known to arrange grid bars between the head plates of the footrests, on which the floor plates are then laid. For this purpose, the head plates of the footrests have pairs of cross-shaped slots on their circumference, into which the side walls at the ends of each grid rod are inserted from above. One of the two other walls of the grid rod is provided with corresponding recesses at its ends in order to enable the ends of the side walls of the grid rod to be inserted into the slots in the head plates of the footrests. On the wall end sections of the grid bars opposite these cutouts, tabs projecting inward are provided in one bar type and, in another bar type, bores are arranged instead of these tabs for the passage of fastening screws. The grid bars with the tabs at their ends are inserted practically loosely into the supporting substructure, while the other Grid type is screwed to the head plates of the footrests. In the latter case, the load-bearing substructure is reinforced even better. However, the two stiffening variants for the load-bearing substructure of the raised floor have so far disadvantageously required the production and storage of two different types of grid bars. In addition, the above-mentioned cutouts in the locking bars result in sharp edges which form a risk of injury to the fitters during assembly of the raised floor and also during subsequent installation work.
Der Erfindung liegt die Aufgabe zugrunde, die obigen Mängel zu beseitigen und einen Rasterstab für Doppelböden zu schaffen, der wahlweise in die tragende Unterkonstruktion der Doppelböden lose eingelegt oder auch mit dieser fest verschraubt werden kann.The invention has for its object to eliminate the above shortcomings and to create a grid rod for raised floors, which can either be inserted loosely into the supporting substructure of the raised floors or can also be screwed tightly thereto.
Gemäß der Erfindung wird obige Aufgabe dadurch gelöst, daß
- a) der Rasterstab der Seitenwände mit derart abgeschrägten Enden aufweist, daß er, von der Seite betrachtet, die Form eines Parallelogramms hat und
- b) jede der beiden anderen, einander gegenüberliegenden Wände des Rasterstabs jeweils die Laschen, Dorne oder dergleichen bzw. Bohrungen, z. B. in Form von Langlöchern für den Durchtritt der Befestigungsschrauben enthält.
- a) the grid bar of the side walls with such bevelled ends that, viewed from the side, it has the shape of a parallelogram and
- b) each of the two other, opposite walls of the grid rod, the tabs, mandrels or the like or holes, z. B. in the form of elongated holes for the passage of the mounting screws.
Ein solcher Rasterstab kann vorteilhaft, je nach seiner ausgewählten Einbauversion, lose in die tragende Unterkonstruktion eingelegt oder auch mit dieser fest verschraubt werden. Für beide Einbauvarianten kann also ein und derselbe Rasterstabtyp verwendet werden, wodurch die Fertigung und Lagerhaltung dieser Stäbe vereinfacht wird. Wenn sich nach bereits erfolgtem Einbau der Rasterstäbe herausstellt, daß der Doppelboden bzw. dessen tragende Unterkonstruktion z. B. abschnittsweise stärker ausgesteift werden muß, braucht man die Rasterstäbe in dem betreffenden Bodenabschnitt nur einfach umzudrehen und mit den Kopfplatten der Fußstützen zu verschrauben. Die bisher in solchen Situationen erforderliche Austauschaktion von Rasterstäben entfällt. Noch ein weiterer Vorteil des erfindungsgemäßen Rasterstabes besteht darin, daß er keine scharfkantige Enden besitzt, die eine Verletzungsgefahr darstellen könnten. Die wahlweise Anordnung des Rasterstabes in der einen oder anderen Einbaulage in der tragenden Unterkonstruktion des Doppelbodens wird dadurch ermöglicht, daß sich in jeder Einbaulage die abgeschrägten Seitenwände des Rasterstabes in die Schlitze an den Kopfplatten der zuvor montierten Fußstützen einstecken lassen. Dabei werden entweder die Laschen, Dorne oder dergleichen in Eingriff mit den Bohrungen in den Kopfplatten der Fußstützen gebracht oder die durch die Bohrungen in den Stabenden hindurchgeführten Befestigungsschrauben in die Bohrungen in den Kopfplatten eingedreht. Es werden zu diesem Zweck selbstschneidende Schrauben verwendet.Such a grid bar can advantageously, depending on its selected installation version, be loosely inserted into the load-bearing substructure or also firmly with it be screwed. The same type of grid bar can therefore be used for both installation variants, which simplifies the manufacture and storage of these bars. If it turns out after installation of the grid bars that the raised floor or its supporting substructure z. B. must be stiffened more in sections, you only need to simply turn the grid bars in the relevant floor section and screw them to the head plates of the footrests. The exchange action of grid bars that was previously required in such situations is no longer necessary. Yet another advantage of the grid rod according to the invention is that it has no sharp-edged ends that could pose a risk of injury. The optional arrangement of the grid rod in one or the other installation position in the load-bearing substructure of the raised floor is made possible in that the slanted side walls of the grid rod can be inserted into the slots on the head plates of the previously mounted footrests in each installation position. Either the tabs, mandrels or the like are brought into engagement with the holes in the head plates of the footrests or the fastening screws passed through the holes in the rod ends are screwed into the holes in the head plates. Self-tapping screws are used for this purpose.
Ausgestaltungen der Erfindung gehen aus den Unteransprüchen hervor. So werden bei einer bevorzugten Ausführungsform die Enden der Seitenwände des Rasterstabes gegenüber den beiden anderen Stabwänden unter einem Winkel von ca. 60° abgeschrägt.Embodiments of the invention emerge from the subclaims. In a preferred embodiment, the ends of the side walls of the grid bar are beveled at an angle of approximately 60 ° with respect to the other two bar walls.
Noch eine weitere Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß auf den beiden anderen einander gegenüberliegenden Wänden als den Seitenwänden des Rasterstabes Höhenausgleichsschichten z. B. Kunststoff- oder Korkstreifen zur Kompensation von Unterlagscheiben auf den Kopfplatten der Fußstützen vorgesehen sind. Man erreicht dadurch die erforderliche satte Auflage der Bodenplatten über praktisch die gesamte Länge der Rasterstäbe. Die Rasterstäbe werden dadurch auch im "lose eingelegten Zustand" fixiert. Die Unterlagscheiben, in der Regel aus Kunststoff hergestellt, dienen in bekannter Weise als Fixierhilfen für die Bodenplatten sowie zur Schalldämmung.Yet another embodiment of the invention is characterized in that on the other two each other opposite walls as the side walls of the grid height compensation layers z. B. plastic or cork strips are provided to compensate for washers on the top plates of the footrests. This achieves the required full support of the floor slabs over practically the entire length of the grid bars. The grid bars are thereby also fixed in the "loosely inserted state". The washers, usually made of plastic, serve in a known manner as fixing aids for the base plates and for sound insulation.

- Figure 1 is a sectional view through part of a raised floor with grid bars according to the invention, one of which is shown in the installation phase.
- FIG. 2 is a side view of one of the grid bars shown in FIG. 1 on an enlarged scale;
- Fig. 3 is a top view of the grid bar of Fig. 2;
- Fig. 4 is an oblique view of part of a footrest of the double floor shown in Fig. 1 with part of a grid bar and

Der in Fig. 1 teilweise gezeigte Doppelboden setzt sich zusammen aus höhenverstellbaren Fußstützen (10), Rasterstäben (11) und quadratischen Bodenplatten (12). Die Fußstützen (10) werden zu Beginn der Montage des Doppelbodens am Rohboden (13) des betreffenden Gebäuderaums befestigt. Jede Fußstütze (10) trägt eine Kopfplatte (14), an deren Umfang kreuzförmig angeordnete Paare von Schlitzen (15) ausgearbeitet sind, die nach außen offen sind. In der Mitte zwischen je zwei Schlitzen (15) ist eine Bohrung (16) vorgesehen.The raised floor partially shown in Fig. 1 settles together from height-adjustable footrests (10), grid bars (11) and square base plates (12). The footrests (10) are attached to the unfinished floor (13) of the building space concerned at the beginning of the assembly of the raised floor. Each footrest (10) carries a head plate (14), on the circumference of which cross-shaped pairs of slots (15) are worked out, which are open to the outside. A bore (16) is provided in the middle between two slots (15).
Die Fußstützen (10) bilden zusammen mit den Rasterstäben (11) die tragende Unterkonstruktion für die Bodenplatten (12), die auf den Rasterstäben (11) aufgelagert werden. Die Rasterstäbe (11) sind gleichartig ausgebildet und es wird nun im folgenden einer derselben unter Bezugnahme auf die Figuren 2 und 3 ausführlich beschrieben.The footrests (10) together with the grid bars (11) form the load-bearing substructure for the floor panels (12), which are supported on the grid bars (11). The grid bars (11) are of identical design and one of them will now be described in detail below with reference to FIGS. 2 and 3.
Der Rasterstab (11) ist aus einem Vierkantrohr hergestellt und seine beiden Seitenwände (17) weisen parallel zueinander abgeschrägte Enden (18) auf. Von der Seite betrachtet hat daher der Rasterstab (11) die Form eines Parallelogramms (Fig. 2). Der Neigungswinkel der Enden (18) der Seitenwände (17) gegenüber den beiden anderen Stabwänden (19 und 20) beträgt z. B. 60°.The grid rod (11) is made from a square tube and its two side walls (17) have bevelled ends (18) parallel to one another. Viewed from the side, therefore, the grid bar (11) has the shape of a parallelogram (Fig. 2). The angle of inclination of the ends (18) of the side walls (17) relative to the other two rod walls (19 and 20) is z. B. 60 °.
An den einander gegenüberliegenden Enden der gemäß Fig. 2 und 3 obenliegenden Wand (19) des Rasterstabs (11) sind Langlöcher (21) für die Hindurchführung von Befestigungsschrauben (27) (Fig. 5) ausgearbeitet. An den Enden der gemäß Fig. 2 und 3 untenliegenden Wand (20) des Rasterstabs (11) sind Laschen (22) ausgestanzt und im rechten Winkel nach innen gebogen. An den Außenseiten dieser Wände (19 und 20) des Rasterstabs (11) sind Höhenausgleichsschichten (23), z. B. Streifen aus Kunststoff oder Kork befestigt, deren Zweck noch erläutert wird.Elongated holes (21) for the passage of fastening screws (27) (FIG. 5) are worked out at the opposite ends of the wall (19) of the grid rod (11) according to FIGS. 2 and 3. At the ends of the wall (20) of the grid rod (11) lying underneath according to FIGS. 2 and 3, tabs (22) are punched out and bent inwards at a right angle. On the outer sides of these walls (19 and 20) of the grid rod (11) are height compensation layers (23), for. B. strips of plastic or cork attached, the purpose of which is explained.
Die Rasterstäbe (11) können wahlweise mit ihrer Wand (19) oder (20) nach oben zeigend mit den Fußstützen (10) verbunden werden. In jedem Fall werden dabei die abgeschrägten Enden (18) der Seitenwande (17) des Rasterstabes (11) seitlich und von oben in die entsprechenden Paare von Schlitzen (15) an zwei gegenüberliegenden Fußstützen (10) eingesteckt, wie in Fig. 1 durch die Pfeile angedeutet ist. Dabei werden gemäß Fig. 4 die Laschen 22 in Eingriff mit den Bohrungen (16) zwischen den entsprechenden Schlitzpaaren (15) gebracht. Die Rasterstäbe (11) sind in diesem Fall lose mit den Kopfplatten (14) der Fußstützen (10) verbunden. Bei der anderen Einbauvariante der Rasterstäbe (11) befindet sich die Wand (19) oben und die Langlöcher (21) überlappen die entsprechenden Bohrungen (16) zwischen den Schlitzpaaren (15) benachbarten Fußstützen (10). In diesem Fall erfolgt die Verbindung des Rasterstabes (11) mit den Kopfplatten (14) der benachbarten Fußstützen (10) durch Befestigungsschrauben (27), die durch die Langlöcher (21) hindurchgeführt und in die Bohrungen (16) in den Kopfplatten (14) eingedreht werden können. Hierfür werden selbstschneidende Befestigungsschrauben (22) verwendet.The grid bars (11) can be connected to the footrests (10) either with their wall (19) or (20) pointing upwards. In any case, the beveled ends (18) of the side walls (17) of the grid rod (11) are inserted laterally and from above into the corresponding pairs of slots (15) on two opposite footrests (10), as shown in Fig. 1 by the Arrows is indicated. 4, the
Wenn auf obige Weise die Rasterstäbe (11) mit den Fußstützen (10) lose verbunden oder fest verschraubt sind, können die Bodenplatten (12) auf den Rasterstäben (11) aufgelegt werden. Zuvor werden jedoch noch auf den Kopfplatten (14) der Fußstützen (10) Unterlagsscheiben (24) angeordnet, die kreuzförmig angeordnete Aussparungen (25) enthalten, um die Paare von Schlitzen (15) nach oben freizulegen, sodaß die Rasterstäbe (11), wie oben beschrieben, an den Kopfplatten (14) angeschlossen werden können. Die Unterlagsscheiben (24) tragen vier symmetrisch angeordnete Anschläge (26) an ihrer Oberseite, welche Positionierungshilfen beim Auflegen der Bodenplatten (12) bilden. Die Unterlagsscheiben (24) sind aus Kunststoff hergestellt und wirken auch schalldämmend. Die Materialdicke der Unterlagsscheiben (24) entspricht der Wanddicke der Rasterstäbe (11) zuzüglich einer der Höhenausgleichsschichten (23). Dadurch ist gewährleistet, daß die Bodenplatten (12) über praktisch die gesamte Länge der Rasterstäbe (11) satt auf diesen aufliegen.If the grid bars (11) are loosely connected to the footrests (10) or screwed tightly in the above manner, the base plates (12) can be placed on the grid bars (11). Beforehand, however, washers (24) are arranged on the head plates (14) of the footrests (10), which contain cross-shaped recesses (25) to expose the pairs of slots (15) upwards, so that the grid rods (11), such as described above, be connected to the head plates (14) can. The washers (24) carry four symmetrically arranged stops (26) on their upper side, which form positioning aids when placing the base plates (12). The washers (24) are made of plastic and also have a sound-absorbing effect. The material thickness of the washers (24) corresponds to the wall thickness of the grid bars (11) plus one of the height compensation layers (23). This ensures that the base plates (12) rest on practically the entire length of the grid bars (11).
Anstelle der aus dem Rasterstabmaterial ausgestanzten und umgebogenen Laschen (22) können beispielsweise auch Dorne, etwa in Form angeschweißter Bolzen vorgesehen sein.Instead of the tabs (22) punched out and bent out of the grid bar material, mandrels, for example in the form of welded bolts, can also be provided.
