Definitions
- the invention relates to a mounting bracket for connecting wood components with each other and on a substrate according to the preamble of claim 1, as used in particular for planks of balcony and patio covers outdoors use.
- U.S. Patent 2,116,737 is a connection system known by which provided with tongue and groove boards are fixed to each other and on a substrate.
- a mounting bracket is used, the vertical web has at the top three claw-shaped perpendicular protruding nails, which penetrate into the planks surfaces.
- On the lower bridge side are bent vertically two Angled soles provided, each of about half bridge length, which are bent in opposite directions (left / right).
- a U-shaped rail which can be screwed to the substrate is used, which holds the clamp over lateral web shoulders, the planks resting on the legs of the rail.
- a connecting element which is suitable for the production of corner joints of boxes.
- the clip is made of a metal band, in which a tongue-shaped angle portion is U-shaped cut out of the band and vertically bent up as a vertical web.
- three corner tongues are formed out as nails, which are taken flat on the boards to be connected.
- a mounting bracket which is a double angle composed of two L-profiles and has a substantially inverted T-section.
- the distance between the planks is at least twice the sheet thickness and can be prepared by a providable in the outer part of the web bridge head accordingly, whereby a good ventilation is made possible.
- soles mounting hole are provided, through which the brackets - and thus the planks - are fastened to the ground.
- the object of the invention is therefore to provide a mounting bracket above genus, which is inexpensive to produce, while maintaining good handling and ensuring good air circulation between the wood parts, and a method for their simple inexpensive production.
- the mounting bracket according to the invention consists of a rectangular, preferably square sole plate, are provided at the middle of the transverse extent of two vertical webs at a small spacing in the longitudinal direction side by side. These webs are punched in opposite directions U-shaped from the sole plate and vertically, ie bent by 90 °. In this case, each of the two webs longitudinally and assigned to its top wearing a perpendicular projecting out of this worked tongue or beak-shaped nail, the nails of the two webs are present in each opposite orientation.
- the great advantage is achieved that a minimum of material is used, namely only a rectangular, preferably square sheet metal plate with an edge length z.
- each web preferably only one nail is provided, and indeed centrally to its longitudinal extent.
- the two perpendicularly but in opposite directions of the two web surfaces freely projecting nails and the clip as a whole, as later mentioned, offset to a centrally present symmetry point laterally symmetrical, so the clip sides are identical in each case with offset by 184 ° of the clip. Due to this point symmetry, the clamp does not have to be specially oriented during assembly, so that an automation of the assembly is conceivable in which the staples can be automatically fed and mounted with a percussion or compressed air press device.
- the nails are vertical, i. bent out of the bridge in a vertical plane relative to the soleplate. If, in addition, the fastening nail is arched downwardly in a trough or arc shape, tapering from the root of the nail to the tip, with a small radius at the tip, the nail shape is strikingly reminiscent of a bird's beak.
- the nail shape is therefore practically the nature apart and extremely rigid over its entire length.
- they can be provided with a comb-shaped rib on their upper longitudinal side.
- the nails can have a notch-shaped groove in the longitudinal center extension for the same purpose.
- Such grooves can also be provided in each case on the underside of the nails.
- the webs Have wavy profiling, whereby the two webs each have opposite bulges. From the respective flat bottoms of the web U-profiles protrude the nails, or from each profiled web a nail protrudes in the middle. This allows a greater width or thickness of the web - and thus a greater distance between the planks can be achieved. So it can be achieved that at a material thickness of z. B. only about 1.5 mm, the width of the web profile is 5 mm or much more, depending on the design of the U-profile.
- an advantageous security against rotation of the mounting brackets according to the invention is achieved in that on the sole plate a positive connection with the ground is formed, by the fact that on the sole plate at least one claw-shaped male blade is formed protruding down or bent out. These may be provided as provided on both longitudinal edges of the sole plate provided edge claws, which are pulled or bent at least 0.2 to 2.0 mm, preferably 0.5 mm deeper than the bottom bottom of the profile indentations of the sole plate. When tightening the mounting screws, these press out of the soleplate down outstanding claw edges or male connectors in the support timber.
- an angled installation of the fastening bores can be provided by embossing.
- the screws can learn from the vertical webs pioneering inclination of 5-30 °, preferably 10-20 °.
- the method for producing the pre-trimmed fastening clip according to the invention consists essentially in that in a rectangular, preferably square sheet metal, with z. B. an edge length of about 5 cm, in the longitudinal and transverse directions offset from each other in opposite directions pointing V-shaped incisions and the corresponding cutouts are formed as beak-shaped nails substantially perpendicular or 90 ° to the sole plate.
- the Befest Trentsklam-mer in its basic version allows a relatively simple punching technology production.
- the mounting bracket in the sole plate-forming sheet are first introduced in the transverse direction opposite and longitudinally successively arranged U-profiles in depressed down manner. Thereafter, a beak-shaped nail is introduced by appropriate punching and bending in the flat bottom of each profiling, after which the U-shaped cutouts just outside and parallel introduced the outer profile lines and the profile webs are pushed up accordingly.
- the bending stiffness of the webs is increased and determines the web width and thus the distance between the planks to each other.
- a relatively small bearing or contact surface with the support timber is achieved by the respective indentation or profiling floor, whereby it is also ensured by the introduction of the screw holes in this profiling area that only this relatively small area is in close contact with the support Lumber is brought.
- the very close arrangement of the screw holes for each designed as a claw edge longitudinal side of the sole plate that the claw edges, which are drawn deeper than the Einbuchtungsböden, by engaging the screws correspondingly claw into the support wood.
- the fastening clip according to the invention in the first embodiment consists of a rectangular sole plate, in which two vertical webs 2 and 3 are provided in the central zone of the longitudinal extent next to each other at a short spacing.
- This vertically oriented U-profiling 4 and 5 respectively has a straight and in the longitudinal direction parallel to each other and to the longitudinal edges of the plate aligned profile bottom 6, with outwardly opening, relatively short legs 7 and 8.
- legs 7 and 8 are at their outer ends relative to the profile bottom 6, 7 and to the longitudinal extent of the sole plate substantially parallel or at least as a short pointing in this direction leg extensions 9 and 10weeterterrent.
- leg extensions 9 and 10 of a web aligned with the profile bottom 6 of the other web, so that each one or the other longitudinal edge 11 or 12 of the sole plate facing surface of the leg extensions 8 and 9 and the profile bottom 6 on the same Line lie and thereby straight and at the same time parallel pads for two miteinan to be joined to the planks 13 and 14 form.
- the gap or distance 15 between the planks can be exactly be-agrees.
- each web 2, 3 protrudes in wesentli beak-shaped nail 16 and 17 perpendicular to the web bottom 6 and at the same time parallel to the sole plate 1, of course, also in opposite directions. This also central to the respective bridge and at the same time close to the top edge.
- These nails 16, 17 are designed to be longer than the height of the webs, so that the correspondingly pointed below the nails extending nail cutout 18 occupies the entire height of the web below the nail and continues to appear in the plate.
- an opening 20 can be seen in the plate 1, which is obtained by introducing a U-cut or incision 21, whereby the contour of the respective web cut from the sole plate and connect the web was bent upright.

Description
Die Erfindung bezieht sich auf eine Befestigungsklammer zur Verbindung von Holzbauteilen untereinander und auf einem Untergrund gemäß Oberbegriff des Patentanspruchs 1, wie sie insbesondere für Bohlen von Balkon- und Terrassenabdeckungen im Freien Verwendung findet.The invention relates to a mounting bracket for connecting wood components with each other and on a substrate according to the preamble of
Verbindungen von Holzteilen mit dem Ziel, im Freien zwei parallele Bohlen auf einem Untergrund so zu befestigen, dass sich zum einen zwischen den Bohlen ein Luftspalt und ein Raum für das Arbeiten des Holzes und zum anderen zwischen dem Untergrund und den Bohlen ebenfalls ein Luftspalt-zur Luftzirkulation und als Maßnahrne gegen das Verfaulen - befindet, sind bekannt.Connections of wooden parts with the aim of attaching two parallel planks on a surface outdoors so that on the one hand between the planks an air gap and a space for working the wood and on the other between the ground and the planks also an air-gap Air circulation and as a measure against the decaying - are known.
So wird in der gängigen Praxis zwischen die Bohlen in Längsrichtung eine Distanzleiste gesteckt und als Unterlage unter die Bohlen werden schmale Leistenstücke gelegt, um einen üblichen Abstand von mindestens 5 mm zu erzielen. Die Befestigung erfolgt dann mittels Schrauben, mit denen die Bohlen vertikal durch die Auflageleistenstücke hindurch auf dem Untergrund befestigt werden. Die Distanzleisten werden anschließend entfernt. Abgesehen davon, dass die Schrauben der durchbohrten Bohlen von oben sichtbar sind, ist häufig die Holzoberfläche aufgebrochen, so dass sich Risse und abstehende Splitter bilden. Über die Löcher dringt Feuchtigkeit und schädigt das Holz und um die Löcher herum bildet die Witterung Verfärbungen, welche die bereits vorher unschöne Ästhetik der Schrauben noch weiter vertieft. Schließlich entstehen bei langen Bohlen um die Schrauben herum Weitungen im Holz, sofern das Holz und der Untergrund verschiedene Lansenausdehnungskoeffizienten aufweisen.Thus, in the usual practice between the boards in the longitudinal direction, a spacer bar inserted and as a base under the planks narrow strip pieces are placed in order to achieve a usual distance of at least 5 mm. The attachment is then by means of screws with which the planks are fastened vertically through the support strip pieces on the ground. The spacer strips are then removed. Apart from the fact that the screws of the pierced planks are visible from above, the wood surface is often broken up, so that cracks and protruding splinters form. Moisture penetrates through the holes and damages the wood, and the weather around the holes forms discolorations, which further deepens the previously unsightly aesthetics of the screws. Finally, in the case of long planks, widenings in the wood are created around the screws, provided the wood and the substrate have different expansion coefficients.

Aufgabe der Erfindung ist es somit, eine Befestigungsklammer oben genannter Gattung anzugeben, die kostengünstig herstellbar ist, unter Beibehaltung einer guten Handhabbarkeit und Sicherstellung guter Luftzirkulation zwischen den Holzteilen, sowie ein Verfahren zu deren einfachen kostengünstigen Herstellung.The object of the invention is therefore to provide a mounting bracket above genus, which is inexpensive to produce, while maintaining good handling and ensuring good air circulation between the wood parts, and a method for their simple inexpensive production.
Diese Aufgabe wird durch eine Befestigungsklammer oben genannter Gattung mit den Merkmalen des Anspruchs 1 und ein Verfahren mit Merkmalen des Anspruchs 10 gelöst. Vorteilhafte Ausgestaltungen sind in den jeweilig rückbezogenen Unteran-sprüchen gekennzeichnet.This object is achieved by a mounting bracket of the above-mentioned type with the features of
Demgemäß besteht die erfindungsgemäße Befestigungsklammer aus einer rechteckigen, vorzugsweise quadratischen Sohlenplatte, an der mittig zu deren Quererstreckung zwei Vertikalstege in geringer Beabstandung in Längsrichtung nebeneinander vorgesehen sind. Diese Stege sind gegenläufig U-förmig aus der Sohlenplatte ausgestanzt und vertikal, d. h. um 90° abgebogen. Dabei trägt ein jeder der beiden Stege längsmittig und seiner Oberseite zugeordnet einen senkrecht abragend aus diesem herausgearbeiteten zungen- oder schnabelförmigen Nagel, wobei die Nägel der beiden Stege in jeweils gegenläufiger Ausrichtung vorhanden sind. Hierdurch wird der große Vorteil erzielt, dass ein Minimum an Material zum Einsatz kommt, nämlich lediglich eine rechteckige, vorzugsweise quadratische Blechplatte mit einer Kantenlänge z. B. von ca. 5 cm, aus der punktsymmetrisch wechselweise Stege U-förmig ausgeschnitten und senkrecht hochgebogen sind. Es wird somit für die Stege kein zusätzliches Material benötigt, sondern lediglich Teile bzw. hochgebogene Ausschnitte der Sohlenplatte. Hierdurch wird mindestens ein Drittel bis fast die Hälfte des Materials im Verhältnis zur Klammer mit doppelwandigem Steg eingespart, was sich ganz erheblich in den Herstellungskosten niederschlägt.Accordingly, the mounting bracket according to the invention consists of a rectangular, preferably square sole plate, are provided at the middle of the transverse extent of two vertical webs at a small spacing in the longitudinal direction side by side. These webs are punched in opposite directions U-shaped from the sole plate and vertically, ie bent by 90 °. In this case, each of the two webs longitudinally and assigned to its top wearing a perpendicular projecting out of this worked tongue or beak-shaped nail, the nails of the two webs are present in each opposite orientation. As a result, the great advantage is achieved that a minimum of material is used, namely only a rectangular, preferably square sheet metal plate with an edge length z. B. of about 5 cm, cut out of the point-symmetrically alternating webs U-shaped and are bent up vertically. It is thus not required for the webs additional material, but only parts or bent-up sections of the sole plate. This will be at least a third to almost saved half of the material in relation to the clamp with double-walled web, which is reflected significantly in the manufacturing cost.
Die in gegenläufiger Ausrichtung in den beiden Stegen angeordneten Befestigungsnägel sind dabei in vorteilhafter Weise so ausgebildet und angeordnet, dass je Steg vorzugsweise nur ein Nagel vorgesehen ist, und zwar mittig zu dessen Längserstreckung. Dabei sind die beiden senkrecht aber gegenläufig von den beiden Stegflächen frei abstehenden Nägel und auch die Klammer insgesamt, wie im Weiteren noch ausgeführt wird, zu einem mittig vorhandenen Symmetriepunkt versetzt seitensymmetrisch, also die Klammerseiten sind bei Versatz um 184° der Klammer jeweils identisch. Durch diese Punktsymmetrie muss die Klammer bei der Montage nicht speziell orientiert werden, so dass eine Automatisierung der Montage denkbar ist, bei der die Klammern automatisch zugeführt und mit einem Schlag- oder Druckluft pressgerät montiert werden können.The arranged in opposite orientation in the two webs mounting nails are formed and arranged in an advantageous manner so that each web preferably only one nail is provided, and indeed centrally to its longitudinal extent. In this case, the two perpendicularly but in opposite directions of the two web surfaces freely projecting nails and the clip as a whole, as later mentioned, offset to a centrally present symmetry point laterally symmetrical, so the clip sides are identical in each case with offset by 184 ° of the clip. Due to this point symmetry, the clamp does not have to be specially oriented during assembly, so that an automation of the assembly is conceivable in which the staples can be automatically fed and mounted with a percussion or compressed air press device.
Dabei sind erfindungsgemäß die Nägel vertikal, d.h. in eine senkrechte Ebene im Verhältnis zu der Sohlenplatte aus den Steg herausgebogen. Ist dann zudem der Befestigungsnagel rinnen- oder bogenförmig nach unten offen gewölbt, und von der Nagelwurzel zur Spitze hin sich verjüngend, mit einem geringen Radius an der Spitze, dann erinnert die Nagelform auffällig an einen Vogelschnabel. Die Nagelform ist somit praktisch der Natur abgesehen und äußerst biegesteif über seine gesamte Länge.In this case, according to the invention, the nails are vertical, i. bent out of the bridge in a vertical plane relative to the soleplate. If, in addition, the fastening nail is arched downwardly in a trough or arc shape, tapering from the root of the nail to the tip, with a small radius at the tip, the nail shape is strikingly reminiscent of a bird's beak. The nail shape is therefore practically the nature apart and extremely rigid over its entire length.
Zur zusätzlichen Verstärkung und gleichzeitig optimierten Führung der Nägel beim Eindringen ins Holz können diese auf ihrer oberen Längsseite mit je einer kammförmigen Rippe versehen sein.For additional reinforcement and at the same time optimized guidance of the nails as they penetrate into the wood, they can be provided with a comb-shaped rib on their upper longitudinal side.
Statt einer Rippe können die Nägel aber zum gleichen Zwecke in längsmittiger Erstreckung eine kerbenförmige Nut besitzen. Solche Nuten können auch jeweils an der Unterseite der Nägel vorgesehen sein. Durch die hierdurch erhaltene zusätzliche Führung der Nägel beim Eindringen ins Holz wird zudem die Montage erleichtert und ein Verdrehen der Befestigungsklammer unterdrückt.Instead of a rib, however, the nails can have a notch-shaped groove in the longitudinal center extension for the same purpose. Such grooves can also be provided in each case on the underside of the nails. By thus obtained additional guidance of the nails when penetrating into the wood, the assembly is also facilitated and suppresses a rotation of the mounting bracket.
Von besonderem Vorteil ist auch, wenn in Platten-Längsrichtung die Stege eine abgeflachte wellenförmige Profilierung besitzen, wodurch die beiden Stege jeweils gegenläufige Ausbauchungen aufweisen. Aus den jeweiligen flachen Böden der Steg-U-Profile ragen die Nägel hervor, bzw. aus jedem profiliertem Steg ragt ein Nagel mittig hervor. Hierdurch kann eine größere Breite bzw. Dicke des Steges - und damit ein größerer Abstand zwischen den Bohlen erreicht werden. So kann erreicht werden, dass bei einer Materialdicke von z. B. nur ca. 1,5 mm die Breite des Stegprofils 5 mm oder wesentlich mehr beträgt, je nach Auslegung des U-Profils.Of particular advantage is also when flattened in plate longitudinal direction, the webs Have wavy profiling, whereby the two webs each have opposite bulges. From the respective flat bottoms of the web U-profiles protrude the nails, or from each profiled web a nail protrudes in the middle. This allows a greater width or thickness of the web - and thus a greater distance between the planks can be achieved. So it can be achieved that at a material thickness of z. B. only about 1.5 mm, the width of the web profile is 5 mm or much more, depending on the design of the U-profile.
Abgesehen von der dadurch erreichten guten Luftzirkulation auch durch den Steg hindurch bzw. an diesem entlang, wird eine optimale Elastizität der Klammer erreicht, die sich bei Schrumpf- oder Quellvorgängen des Holzes sehr positiv auswirkt, da die Klammer in solchen Fällen sozusagen mitarbeitet, sich also elastisch zusammendrücken oder auseinanderziehen läßt. Dies sowohl durch die Zweiteiligkeit des Steges bzw. die zwei Stege, als auch durch die entsprechenden Stegprofilierungen.Apart from the achieved thereby good air circulation through the web or along this along, an optimal elasticity of the clip is achieved, which has a very positive effect in shrinking or swelling processes of the wood, since the clip cooperates in such cases, so to speak, so elastically compress or pull apart. This is due to the bipartite nature of the web or the two webs, as well as the corresponding web profilings.
Eine vorteilhafte Sicherheit gegen Verdrehen der montierenden Klammern wird erfindungsgemäß dadurch erreicht, dass über die Sohlenplatte ein Formschluss mit dem Untergrund gebildet wird, und zwar dadurch, dass an der Sohlenplatte mindestens eine krallenförmige Messerleiste nach unten hervorstehend eingeformt bzw. herausgebogen ist. Diese können als an beiden Längskanten der Sohlenplatte hervorragt vorgesehene Kantenkrallen vorgesehen sein, die mindestens 0,2 bis 2,0 mm, vorzugsweise 0,5 mm tiefer gezogen bzw. gebogen sind, als die Bodenunterseite der Profil-Einbuchtungen der Sohlenplatte. Beim Anziehen der Befestigungsschrauben drücken sich diese aus der Sohlenplatte nach unten herausragenden Krallenkanten oder Messerleisten ins Auflageholz.An advantageous security against rotation of the mounting brackets according to the invention is achieved in that on the sole plate a positive connection with the ground is formed, by the fact that on the sole plate at least one claw-shaped male blade is formed protruding down or bent out. These may be provided as provided on both longitudinal edges of the sole plate provided edge claws, which are pulled or bent at least 0.2 to 2.0 mm, preferably 0.5 mm deeper than the bottom bottom of the profile indentations of the sole plate. When tightening the mounting screws, these press out of the soleplate down outstanding claw edges or male connectors in the support timber.
Um zusätzlich einen Zug in Richtung Brett beim Festziehen der Befestigungsschrauben zu erreichen, ist durch eine Hochprägung eine winklige Aufstellung der Befestigungsbohrungen vorsehbar. Dadurch können die Schrauben eine von den Vertikal-Stegen wegweisende Neigung von 5-30°, vorzugsweise 10-20° erfahren.In order to additionally achieve a pull in the direction of the board when tightening the fastening screws, an angled installation of the fastening bores can be provided by embossing. As a result, the screws can learn from the vertical webs pioneering inclination of 5-30 °, preferably 10-20 °.
Das Verfahren zur Herstellung der vorbeschnebenen erfindungsgemäßen Befestigungsklammer besteht im wesentlichen darin, dass in einem rechteckigen, vorzugsweise quadratischen Blech, mit z. B. einer Kantenlänge von ca. 5 cm, in Längs- und Querrichtung zueinander versetzt gegenläufig weisende V-förmige Einschnitte eingebracht und die entsprechenden Ausschnitte als schnabelförmige Nägel im Wesentlichen senkrecht bzw. um 90° zur Sohlenplatte herausgeformt werden. Jeweils gegenläufig um die Nageizungen herum wird ein U-förmiger Einschnitt eingebracht und in gleicher Schwenkrichtung wie die Nagelzungen senkrecht abgebogen, so dass die Nägel schließlich jeweils horizontal und damit parallel über der Steg-Ausschnittsöffnung sich befinden. Es ist zu erkennen, dass die Befestigungsklam-mer in ihrer Grundausführung eine relativ einfache stanztechnische Herstellung ermöglicht.The method for producing the pre-trimmed fastening clip according to the invention consists essentially in that in a rectangular, preferably square sheet metal, with z. B. an edge length of about 5 cm, in the longitudinal and transverse directions offset from each other in opposite directions pointing V-shaped incisions and the corresponding cutouts are formed as beak-shaped nails substantially perpendicular or 90 ° to the sole plate. In each case in opposite directions around the Nageizungen around a U-shaped incision is introduced and bent in the same pivoting direction as the nail fences perpendicular, so that the nails are finally each horizontally and thus parallel over the web-cutout opening. It can be seen that the Befestigungsklam-mer in its basic version allows a relatively simple punching technology production.
Von Vorteil ist, wenn bei der Herstellung der Befestigungsklammer in das die Sohlenplatte bildende Blech zuerst in Querrichtung gegenläufig ausgebildete und in Längsrichtung nacheinander angeordnete U-Profilierungen in nach unten eingedrückter Weise eingebracht werden. Danach wird in den ebenen Boden einer jeweiligen Profilierung ein schnabelförmiger Nagel durch entsprechendes Stanzen und Biegen eingebracht, wonach die U-förmigen Ausschnitte knapp außerhalb und parallel der äußeren Profillinien eingebracht und die Profilstege entsprechend hochgedrückt werden. Durch diese im ersten Herstellungsschritt eingebrachten, sich in Querrichtung erstreckenden U-Einbuchtungen bzw. Profilierungen, wird einerseits die Biegesteifigkeit der Stege erhöht sowie die Stegbreite bestimmt und damit der Abstand der Bohlen zueinander. Andererseits wird durch den jeweiligen Einbuchtungs- bzw. Profilierungsboden eine relativ geringe Auflage- bzw. Kontaktfläche mit dem Auflageholz erreicht, wobei durch die Einbringung der Schraubenlöcher in diesem Profilierungsbereich auch sichergestellt ist, dass nur dieser relativ geringe Be- ' reich in engen Kontakt mit dem Auflageholz gebracht wird. Zudem ist durch die sehr nahe Anordnung der Schraubenlöcher zur jeweiligen, als Krallenkante ausgebildeten Längsseite der Sohlenplatte sichergestellt, dass die Krallenkanten, die tiefer gezogen sind als die Einbuchtungsböden, sich durch das Einziehen der Schrauben entsprechend in das Auflagenholz einkrallen.It is advantageous if in the manufacture of the mounting bracket in the sole plate-forming sheet are first introduced in the transverse direction opposite and longitudinally successively arranged U-profiles in depressed down manner. Thereafter, a beak-shaped nail is introduced by appropriate punching and bending in the flat bottom of each profiling, after which the U-shaped cutouts just outside and parallel introduced the outer profile lines and the profile webs are pushed up accordingly. By introduced in the first manufacturing step, extending in the transverse direction U-indentations or profiles, on the one hand, the bending stiffness of the webs is increased and determines the web width and thus the distance between the planks to each other. On the other hand, a relatively small bearing or contact surface with the support timber is achieved by the respective indentation or profiling floor, whereby it is also ensured by the introduction of the screw holes in this profiling area that only this relatively small area is in close contact with the support Lumber is brought. In addition, it is ensured by the very close arrangement of the screw holes for each, designed as a claw edge longitudinal side of the sole plate that the claw edges, which are drawn deeper than the Einbuchtungsböden, by engaging the screws correspondingly claw into the support wood.

characterised in that- the two webs are punched out of the floor plate in opposite directions in a U-shape and are bent vertically upwards,- at least one nail (16) is provided, which projects perpendicularly from the first vertical web (2) and is carved out therefrom in a tongue or beak shape,- the second web (3) carrying a perpendicularly projecting nail (17), which is carved out therefrom in a tongue or beak shape, and the nails (16, 17) of the first and second web being of respectively opposite orientations. - Fixing bracket according to claim 1, characterised in that the respective nail (16, 17) is punched out of the floor and web material and is deflected perpendicularly in the same bending direction as the web (2, 3) and thus faces in the same direction as the web punch opening (20).
- Fixing bracket according to claim 1, characterised in that the webs (2, 3) comprise U-profilings (4, 5) in respectively opposite directions, comprising opening up, relatively short profile limbs (7, 8), the limb ends (9, 10) of one web being located at the same longitudinal extension as the straight U-profile base of the respective other web.
- Fixing bracket according to claim 3, characterised in that the respective profiling, present symmetrically about the centre of the web, extending away from the rear face of the web, is also provided as an indentation (22) in the floor plate (1).
- Fixing bracket according to claim 4, characterised in that the hole (23) is arranged in the indentation (22), and thus at the opposite central extension from the web nail (16, 17).
- Fixing bracket according to claim 4, characterised in that embossing (31), placed on at an angle and at least semi-circular, preferably ¾-circular, at least at the size of the contact area of the screw heads, is provided in the indentation (22), on the side facing the vertical web (2, 3), concentrically with the indentation (23), the axis (32) of the hole (23) being arranged pointing away from the vertical web (2, 3) at an angle α of 5-30°, preferably of 10-20°.
- Fixing bracket according to claims 3 to 5, characterised in that the profiling of the webs (2, 3) and the floor point is configured symmetrically about a central point in such a way that the respective profile base outer surface (6) of one web is located flush in the longitudinal direction, that is to say at the same transverse distance from the longitudinal central line of the bracket, as the U-limb extensions (9, 10) of the other web which have parallel axes, in such a way that in each case a board contact is provided on both sides of the web, specifically in each case on two limb extensions and one profile base.
- Fixing bracket according to claim 7, characterised in that the depth of the U-profiling (4, 5) of the webs (2, 3) can be configured so as to correspond to the gap or spacing (15) to be provided between the boards (13 and 14) and the wood (24) to be placed on the boards (13, 14), for example at a distance of 5 mm.
- Fixing bracket according to claim 1, characterised in that the two floor plate longitudinal edges (11, 12) which are parallel to the longitudinal extension of the web are bent (folded) downwards, in such a way that they are pulled at least 0.2 to 2.0 mm, preferably 0.5 mm lower than the base undersides (25) of the profile indentation (22), forming mutually longitudinally parallel claw edges (26).
- Fixing bracket according to claims 1 and 2, characterised in that the nails (16, 17) which are arranged close to the respective web upper side are of a nail length which is greater than the distance of the nail root from the floor plate, in such a way that the corresponding (nail) V-portion (18) extends into the floor indentation (22) in the direction towards the screw penetration hole (23).
- Fixing bracket according to claim 10, characterised in that the nails (16, 17) comprise a comb-shaped rib (27) or a notch-shaped groove (34), on the upper side thereof in the centre of the longitudinal extension, and a groove (35), on the underside thereof.
- Method for manufacturing the fixing bracket according to claims 1 to 11, in whichV-portions (18), which face in opposite directions, mutually offset in the longitudinal and transverse direction, are formed in a rectangular, preferably square metal floor plate sheet, and are formed in a beak shape, pressed downwards substantially perpendicular (90°) to the plate (1) as tongue/nails (16, 17),a U-shaped incision (21) is made in the opposite direction around the nails or the incisions (18) in each case, and bent upwards in the same clockwise direction as the nails (16, 17), in such a way that the nails (16, 17) are subsequently each located horizontally and thus parallel above the web punch opening (20).
- Method according to claim 12, characterised in that Uprofilings, orientated or formed in a transverse direction in opposite directions and arranged side by side, are initially formed as an indentation (22), impressed downwards, in the metal sheet forming the floor plate (1), the beak-shaped nails (16, 17) subsequently being formed in the base of the profiling by punching and bending, and the U-portions (21) subsequently being formed at least slightly outside and parallel to the profiling and the profile webs (2, 3) which are thus incised being bent outwards by 90°.
