Definitions
- the present invention relates to a lintel for supporting one or more layers of wall when masonrying buildings, such as bridging wall openings, carrying brick facades and the like is the load-bearing part of the fall.
- Wall lintels for bridging wall openings are known in many different versions (DE-OS 1.966.687, 2.533.856).
- lintels are sought which at least partly have space in the joint between two stone layers and are therefore made from a relatively thin sheet material.
- the requirement for a low construction height means that the moment of inertia or the bending resistance is very high is small and the fall can only bear light loads.
- tensioning straps or tie rods have been proposed (DE-OS 2,724,755) which are fastened to the leg end regions of the fall. By attaching these straps in the brick butt joints, they can be accommodated inconspicuously.
- the purpose of the invention is to propose a lintel of the type mentioned at the outset, which has sufficient strength to support the wall layer, which is light in weight and therefore has little influence on the loading conditions due to its own weight, the torsional forces caused by one-sided loading of the lintel during the walling can accommodate, and which is bendable from a thin sheet metal profile in a simple manufacturing process without complex welding operations.
- the invention is based on the object to create a wall lintel of this type which, despite its lightweight construction, can absorb large loads during masonry work, but after the mortar has set, it is not an obstacle in the way between the bricks.
- the leg or legs each with one in its longitudinal direction extending material weakening, for example, a series of slots, perforations and / or one or more crevices, grooves and the like. Or combinations thereof is provided, the material weakening being designed so that the load capacity in the plane of the leg is only slightly reduced, while Material weakening at the same time forms a breakage indicator when the leg is bent along this.
- material weakening for example, a series of slots, perforations and / or one or more crevices, grooves and the like. Or combinations thereof is provided, the material weakening being designed so that the load capacity in the plane of the leg is only slightly reduced, while Material weakening at the same time forms a breakage indicator when the leg is bent along this.
- the lintel 1 according to the invention according to FIGS. 1-3 is mainly Z-shaped in cross section, one leg 2 consisting of two at an angle to one another standing parts 2 and 3, which have the shape of an inverted V's in cross section.
- the angle between the central part 4 of the Z-shaped profile and the mentioned first leg 2 is somewhat greater than 90 °, so that when the central part 4 assumes a horizontal position, it is inclined upwards and outwards.
- the part 3 of the inclined leg 2 mainly forms a right angle with the horizontal central part 4, which can be brought to bear against a building.
- the second leg 5 of the Z-shaped sheet metal profile is mainly bent at right angles to the central part 4 and serves as a load-bearing stiffening web during the masonry and until the masonry has received its own strength to be self-supporting.
- the leg 5 is provided with material weakenings 6 along its entire length.
- these material weaknesses consist of slot-shaped openings with narrow material parts between the individual slots, which are arranged in a row at a distance from the bending edge, which suitably corresponds to the thickness of a wall joint.
- the material weakening in the leg 5 is arranged so that the load-bearing capacity of the leg is only insignificantly reduced in its plane.
- Other types of material weakening - as slits or perforations are possible, for example cracks, grooves or combinations of the measures mentioned.
- the section of the leg 5, which extends from its free end edge to the material weakening 6, can either can be bent towards the central part 4 of the lintel or this section can also be broken off by repeated bending along the material weakening 6.
- the remaining part of the leg 5 can serve as a drip nose.
- the free end edge of the leg is bent through 180 °, as can be seen from FIG. 1.
- the horizontal middle part 4 of the lintel 1 is provided on the side facing away from the leg 5 with a punch 7 through which a tongue 8 is formed, which is separated on three sides by the punch from the middle part.
- the tongue 8 is normally in the same plane as the central part 4 and can be bent downward by about 90 ° and thus forms a support so that the rear edge of the lintel cannot be inclined due to the load on the bricks in the soft mortar.
- tensioning straps 11 which are connected to the legs 2 and 5 in such a way that a load can be transferred.
- the tensioning straps are attached between the butt joints of the bricks and consist of a plate or the like.
- the ends are provided with bends 23, 24 which can be inserted partly into the slots 6 of the leg 5 and partly bent over the free end edge of the leg 2 can be.
- the lintel shown in Fig. 1-3 is intended for bridging openings at first hand, but in addition to its function as such it also has to serve as a water drain for the water at the Back of a facade covering or the like.
- the lintel shown in FIGS. 1-3 cannot be used since the leg 2 cannot be accommodated and should not be visible either.
- the lintel 9 shown in Figs. 4 and 5 can be used, which is mainly U-shaped and can be used wherever the underside of the wall opening is covered by, for example, a window or door frame.
- the legs 12, 13 are designed with a relatively large web height, which absorb most of the loads that occur. Material weaknesses 6 are provided in both legs 12, 13 at some distance from the bending edge.
- the leg sections 12, 13 are removed in accordance with the length of the support surface until the material is weakened, as is illustrated, for example, in FIG. 2.
- the parts of the legs that extend into the wall opening remain intact during the brickwork until the mortar has set, thereby absorbing the fall from one or more layers of stone.
- the outer sections of the legs 12, 31 can be broken off until the material weakening 6 by repeated back and forth, as in FIG. 5, right part the illustration is shown. In this training, the fall can possibly be covered with mortar.
- the exemplary embodiment according to FIGS. 6 and 7 shows a lintel 16 which is used where the masonry structure is not self-supporting and can only be achieved by reinforcement or the like.
- the lintel 16 consists of a mainly U-shaped sheet metal profile which is formed in the middle part 17 between the legs 19 and 20 with a roof-shaped part 18 running in the longitudinal direction of the lintel.
- Material weaknesses 6 are again provided in the vicinity of the bending edges, the slots in the roof-shaped part 18 being provided in the immediate vicinity of the bend, while the slots in the legs 19 and 20 are spaced apart by approximately a wall joint.
- the roof-shaped part 18 is introduced into a recess 21 in the bricks which form the first layer, the remaining cavity of the recess 21 being filled with mortar or the like. As soon as the masonry has received sufficient load-bearing capacity, either only the legs 19 and 20 can be broken off or broken along their material weaknesses 6 or the legs 19, 20 together with the middle parts 17 on both sides of the roof-shaped part 18 can be broken off along the slots 6.
- This type of reinforcement l8 is particularly useful for large-volume stones, such as gas concrete blocks, light clinker blocks, concrete blocks, concrete hollow blocks, etc.
- the wall lintels according to the invention consist of relatively thin steel sheet (for example 0.7-1.0 mm thick), but it is also possible to produce the lintels from so-called expanded metal nets, the weakening of the material being achieved by means of cracks or grooves.

Abstract
Description
Die vorliegende Erfindung betrifft einen Mauersturz zur Abstützung einer oder mehrerer Mauerschichten beim Mauern von Bauwerken, wie z.B Überbrücken von Wandöffnungen, Tragen von Ziegelfasaden und dgl., und der aus einem verhältnismässig dünnem Blechprofil mit mindestens einem Schenkel besteht, welcher den Steg des Sturzes bildet und der belastungsaufnehmende Teil des Sturzes ist.The present invention relates to a lintel for supporting one or more layers of wall when masonrying buildings, such as bridging wall openings, carrying brick facades and the like is the load-bearing part of the fall.
Mauerstürze zum Uberbrücken von Wandöffnungen sind in vielen verschiedenen Ausführungen bekannt (DE-OS 1.966.687, 2.533.856). Um so wenig auffällig zu sein wie möglich, werden Stürze angestrebt die zumindestens zu einem Teil in der Fuge zwischen zwei Steinschichten Platz erhalten und deshalb aus einem verhältnismässig dünnem Blechmaterial hergestellt werden. Die ForderunG auf geringe Konstruktionshöhe führt jedoch mit, dass das Trägheitsmoment bzw der Biegewiderstand sehr klein ist und der Sturz nur geringe Belastungen aufnehmen kann. Zur Verbesserung der Tragfähigkeit solcher Stürze sind Spannbänder oder Spannstäbe vorgeschlagen worden, (DE-OS 2.724.755) welche an den Schenkelendbereichen des Sturzesbefestigt werden. Durch Anbringen dieser Spannbänder in den Ziegelstossfugen können diese unauffällig untergebracht werden. In vielen Fällen ist die Anwendung von L-oder Z-förmigen Profilen nicht möglich, da der die Belastung aufnehmende Steg oder Schenkel nicht versteckt untergebracht werden kann bzw ni-cht sichtbar sein soll. Verschiedene Gründe dafür können vorliegen sowohl bautechnische wie auch ästhetische solche. Ein Mauersturz zum Uberbrücken einer Fenster- oder Türöffnung kann nicht mit mehreren Zentimetern in die öffnung hineinragen, da dieser Platz für den Fenster- oder Türrahmen in Anspruch genommen werden muss.Wall lintels for bridging wall openings are known in many different versions (DE-OS 1.966.687, 2.533.856). In order to be as unobtrusive as possible, lintels are sought which at least partly have space in the joint between two stone layers and are therefore made from a relatively thin sheet material. However, the requirement for a low construction height means that the moment of inertia or the bending resistance is very high is small and the fall can only bear light loads. To improve the load-bearing capacity of such falls, tensioning straps or tie rods have been proposed (DE-OS 2,724,755) which are fastened to the leg end regions of the fall. By attaching these straps in the brick butt joints, they can be accommodated inconspicuously. In many cases, the use of L-shaped or Z-shaped profiles is not possible, since the web or leg that absorbs the load cannot be hidden or should not be visible. There can be various reasons for this, both structural and aesthetic. A lintel to bridge a window or door opening cannot protrude several centimeters into the opening, since this space for the window or door frame must be used.
Der Zweck der Erfindung ist einen Mauersturz der eingangs erwähnten Art vorzuschlagen, der beim Mauern die genügende Festigkeit zu Abstützung der Mauerschicht besitzt, der gewichtsmässig leicht ist und dadurch durch sein Eigengewicht die Belastungsvoraussetzungen wenig beeinflusst, der Torsionskräfte bedingt durch einseitige Belastung des Sturzes während des Mauerns aufnehmen kann, und der aus einem dünnen Blechprofil auf einfache Herstellungsweise biegbar ist ohne aufwendige Schweissoperationen. Der Erfindung liegt die Aufgabe zu Grunde eienen Mauersturz dieser Art zu schaffen der trotz seiner Leichtbauweise während der Mauerarbeit grosse Belastungen aufnehmen kann, nach erfolgter Abbindung des Mörtels jedoch zwischen den Ziegelsteinen nicht behindernd im Wege ist. Diese Aufgabe wurde dadurch gelöst, dass der bzw die Schenkel je mit einer in dessen Längsrichtung sich erstreckenden Materialschwächung beispielsweise einer Reihe von Schlitzen,Perforierungen und/oder einem oder mehreren Ritzen, Rillen und dgl. oder Kombinationen davon versehen ist, wobei die Materialschwächung so ausgebildet ist, dass die Belastungsfähigkeit in der Ebene des Schenkels nur unbedeutend vermindert wird, während die Materialschwächung gleichzeitig eine Bruchanzeige beim Biegen des Schenkels längs dieser bildet.The purpose of the invention is to propose a lintel of the type mentioned at the outset, which has sufficient strength to support the wall layer, which is light in weight and therefore has little influence on the loading conditions due to its own weight, the torsional forces caused by one-sided loading of the lintel during the walling can accommodate, and which is bendable from a thin sheet metal profile in a simple manufacturing process without complex welding operations. The invention is based on the object to create a wall lintel of this type which, despite its lightweight construction, can absorb large loads during masonry work, but after the mortar has set, it is not an obstacle in the way between the bricks. This object was achieved in that the leg or legs each with one in its longitudinal direction extending material weakening, for example, a series of slots, perforations and / or one or more crevices, grooves and the like. Or combinations thereof is provided, the material weakening being designed so that the load capacity in the plane of the leg is only slightly reduced, while Material weakening at the same time forms a breakage indicator when the leg is bent along this.

- Fig. 7 ist ein Schnitt durch eine Mauer versehen mit dem Sturz gemäss Fig. 6.FIG. 7 is a section through a wall provided with the lintel according to FIG. 6.
Der erfindungsgemässe Mauersturz 1 nach den Figuren 1-3 ist im Querschnitt hauptsächlich Z-förmig, wobei der eine Schenkel 2 aus zwei im Winkel zueinander stehenden Teilen 2 und 3 besteht, die im Querschnitt die Form eines inverntierten V's besitzen. Der Winkel zwischen dem Mittelteil 4 des Z-förmigen Profiles und dem erwähnten ersten Schenkel 2 ist etwas grösser als 90°, so dass wenn der Mittelteil 4 horizontale Stellung einnimmt diese schräg nach oben und aussen geneigt ist. Das Teil 3 des geneigten Schenkels 2 bildet hauptsächlich rechten Winkel mit dem horizontellen Mittelteil 4, welches zur Anliegung gegen einen Baukörper gebracht werden kann.The lintel 1 according to the invention according to FIGS. 1-3 is mainly Z-shaped in cross section, one leg 2 consisting of two at an angle to one another standing
Der zweite Schenkel 5 des Z-förmigen Blechprofils ist hauptsächlich rechtwinklig gegen den Mittelteil 4 abgebogen und dient als belastungsaufnehmender Versteifungssteg während dem Mauern und bis das Mauerwerk genügende eigene Festigkeit erhalten hat um selbsttragend zu sein.The second leg 5 of the Z-shaped sheet metal profile is mainly bent at right angles to the central part 4 and serves as a load-bearing stiffening web during the masonry and until the masonry has received its own strength to be self-supporting.
Der Schenkel 5 ist mit Materialschwächungen 6 längs seiner ganzen Länge versehen. In dem dargestellten Ausführungsbeispiel bestehen diese Materialschwächungen aus schlitz förmigen Durchbrechungen mit schmalen Materialpartien zwischen den einzelnen Schlitzen, die in einer Reihe auf Abstand von der Umbiegungskante angeordnet sind, welcher zweckmäsig der Dicke einer Mauerfuge entspricht. Die Materialschwächung im Schenkel 5 ist so angeordnet, dass die Tragfähigkeit des Schenkels in dessen Ebene nur unbedeutend verringert wird. Auch andere Typen von Materialschwächungen - als Schlitze oder Perforierungen sind möglich, beispielsweise Ritze, Rillen oder auch Kombinationen zwischen den genannten Massnahmen. Sobald das Mauerwerk eigene Tragfähigkeit erhalten hat, kann der Abschnitt des Schenkels 5, der sich von dessen freien Endkante bis zur Materialschwächung 6 erstreckt, entweder in Richtung gegen das Mittelteil 4 des Sturzes abgebogen werden oder auch kann dieser Abschnitt durch wiederholtes Umbiegen längs der MaterialschwächunG 6 abgebrochen werden. Der übriggebliebene Teil des Schenkels 5 kann als Tropfnase dienen.The leg 5 is provided with material weakenings 6 along its entire length. In the illustrated embodiment, these material weaknesses consist of slot-shaped openings with narrow material parts between the individual slots, which are arranged in a row at a distance from the bending edge, which suitably corresponds to the thickness of a wall joint. The material weakening in the leg 5 is arranged so that the load-bearing capacity of the leg is only insignificantly reduced in its plane. Other types of material weakening - as slits or perforations are possible, for example cracks, grooves or combinations of the measures mentioned. As soon as the masonry has its own load-bearing capacity, the section of the leg 5, which extends from its free end edge to the material weakening 6, can either can be bent towards the central part 4 of the lintel or this section can also be broken off by repeated bending along the material weakening 6. The remaining part of the leg 5 can serve as a drip nose.
Um die Biegefestigkeit und Torsionssteifigkeit des Sturzes zu erhöhen, ist die freie Endkante des Schenkels 180° umgebogen, so wie dies aus Fig. 1 hervorgeht.In order to increase the bending strength and torsional rigidity of the lintel, the free end edge of the leg is bent through 180 °, as can be seen from FIG. 1.
Das horizontale Mittelteil 4 des Sturzes 1 ist auf der dem Schenkel 5 abgewandten Seite mit einer Ausstanzung 7 versehen, durch die eine Zunge 8 gebildet weird, welche auf drei Seiten durch die Ausstanzung vom Mittelteil getrennt ist. Die Zunge 8 liegt normalerweise in gleicher Ebene wie das Mittelteil 4 und kann von Hand etwa 90° nach unten gebogen werden und bildet dadurch eine Abstützung, so dass sich die Hinterkante des Sturzes durch die Belastung der Ziegelsteine im weichen Mörtel nicht schräg stellen kann.The horizontal middle part 4 of the lintel 1 is provided on the side facing away from the leg 5 with a punch 7 through which a tongue 8 is formed, which is separated on three sides by the punch from the middle part. The tongue 8 is normally in the same plane as the central part 4 and can be bent downward by about 90 ° and thus forms a support so that the rear edge of the lintel cannot be inclined due to the load on the bricks in the soft mortar.
Eine zusätzliche Tragfähigkeit des Mauerzuges wird mit Hilfe von Spannbändern 11 erhalten, die mit den Schenkeln 2 und 5 so verbunden werden dass eine Lastübertragung erfolgen kann. Die Spannbänder werden zwischen den Stossfugen der Ziegelsteine angebracht und bestehen aus einem Platteisen oder dgl. das an den Enden mit Umbiegungen 23,24 versehen ist die teils in die Schlitze 6 des Schenkels 5 eingeführt werden können und teils über die freie Endkante des Schenkels 2 gebogen werden können.An additional load-bearing capacity of the wall pull is obtained with the aid of tensioning
Der in Fig. 1-3 dargestellte Sturz ist in erster Hand zum Uberbrücken von Öffnungen vorgesehen, hat aber neben seiner Funktion als solcher auch als Wasserableiter zu dienen,für das Wasser das an der Rükseite einer Fasadenbedeckung oder dgl. abläuft.The lintel shown in Fig. 1-3 is intended for bridging openings at first hand, but in addition to its function as such it also has to serve as a water drain for the water at the Back of a facade covering or the like.
Fürr massive Mauerwerke und dgl. kann der in Fig. 1-3 dargestellte Sturz nicht angewandt werden da der Schenkel 2 nicht untergebracht werden kann und sichtbar auch nicht sein soll. In solchen Fällen kann der in Fig. 4 und 5 gezeigte Sturz 9 zur Anwendung kommen, welcher hauptsächlich U-förmig ist und überall dort zum Einsatz gebracht werden kann wo die Unterseiteder Maueröffnung durch beispielsweise einen Fenster- oder Türrahmen verdeckt wird. Um den Sturz 9 genügende Tragfähigkeit geben zu können sind die Schenkel 12,13 mit verhältnismässig grosser Steghöhe ausgebildet, welche den grössten Teil der auftretenden Belastungen aufnehmen. Materialschwächungen 6 sind in beiden Schenkeln 12,13 auf einigem Abstand von der Biegungskante vorgesehen. An den Endpartien des Sturzes werden entsprechend der Länge der Auflagefläche die Schenkelabschnitte 12, 13 bis zur Materialschwächung entfernt, so wie das beispielsweise in Fig. 2 veranschaulich ist. Die Teile der Schenkel welche sich in die Maueröffnung erstrecken verbleiben während des Mauerns bis zur Abbindung des Mörtels intakt und nehmen dadurch die Belastung des Sturzes von einer oder mehreren Steinschichten auf. Sobald das Mauerwerk genügende Festigkeit erhalten hat, so dass es ihr eigenes Gewicht zu tragen vermag, können die äusseren Abschnitte der Schenkel 12,31 bis zur Materialschwächung 6 durch wiederholtes hin- und herbiegen abgebrochen werden, so wie das in Fig. 5, rechter Teil der Abbildung dargestellt ist. In dieser Ausbildung kann eventuell der Sturz durch Mörtel eingekleidet werden.For massive masonry and the like, the lintel shown in FIGS. 1-3 cannot be used since the leg 2 cannot be accommodated and should not be visible either. In such cases, the
Es ist auch möglich den äusseren Abschnitt der Schenkel 12,13 gegen die Unterseite des Mittelteils 10 des Sturzes zu biegen, so wie dies im linken Teil der Fig. 5 verdeutlicht ist. Soll in die Maueröffnung ein Tür- oder Fensterrahmen 14 eingesetztwerden, kann zumindestens ein Teil des Zwischenraumes zwischen Rahmen und Steinschicht um den Sturz 9 herum einen Fugmasse eingeführt werden, die vom Tür- oder Fensterfutter überdeckt werden.It is also possible to bend the outer section of the
Das Ausführungsbeispiel gemäss den Figuren 6 und 7 zeigt einen Sturz 16 der dort zur Anwendung kommt wo der Mauerverband nicht selbsttragend ist und nur durch Armeierung oder dgl. erziehlt werden kann. Der Sturz 16 besteht aus einem haupsächlich U-förmigen Blechprofil, das in dem Mittelteil 17 zwischen den Schenkeln 19 und 20 mit einer in Längsrichtung des Sturzes verlaufenden dachförmigen Partie 18 ausgebildet ist. In der Nähe der Biecungskanten sind wieder Materialschwächungen 6 vorgesehen, wobei die Schlitze in der dachförmigen Partie 18 in unmittelbarar Nähe der Umbiegung vorgesehen sind, während die Schlitze in den Schenkeln 19 und 20 einen Abstand von etwa einer Mauerfuge aufweisen.The exemplary embodiment according to FIGS. 6 and 7 shows a
Die dachförmigen Partie 18 wird in einer Aussparung 21 in den Mauersteinen die die erste Schicht bilden eingeführt, wobei der übrige Hohlraum der Aussparung 21 mit Mörtel oder dgl. ausgefüllt wird. Sobald das Mauerwerk genügende Tragfähigkeit erhalten hat, können entweder nur die Schenkel 19 und 20 längs ihren Materialschwächungen 6 abgebrochen oder umgebrochen werden oder auch die Schenkel 19,20 mitsamt den Mittelteilen 17 auf beiden Seiten der dachförmigen Partie l8 längs den Schlitzen 6 abgebrochen werden.The roof-
Diese Art von Armierung l8 ist besonders für grossvolumige Steine zweckmässig, wie z,B Gasbetonsteine leichtklinker Steine, Betonsteine, Betonhohlsteine usw.This type of reinforcement l8 is particularly useful for large-volume stones, such as gas concrete blocks, light clinker blocks, concrete blocks, concrete hollow blocks, etc.
Die erfindungsgemässen Mauerstürze bestehen aus verhältnismässig dünnem Stahlblech (beispielsweise 0,7-1,0mm Dicke), es ist aber auch möglich die Stürze aus so genannten Streckmetallnetzen herzustellen, wobei die Materialschwächung durch Ritze oder Rillen erziehlt wird.The wall lintels according to the invention consist of relatively thin steel sheet (for example 0.7-1.0 mm thick), but it is also possible to produce the lintels from so-called expanded metal nets, the weakening of the material being achieved by means of cracks or grooves.
