Description

Die Erfindung betrifft eine Flachdecke gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a flat ceiling according to the preamble of claim 1.

Gemäß Sonderdruck " Elementdecken im Durchstanzbereich von Flachdecken" der Zeitschrift "Betonwerk + Fertigteil-Technik", Heft 6/1997, S. 96 - 104 , ist es zum Verhindern des Durchstanzversagens in punktgestützten Flachdecken bekannt, im Bereich der Stützung senkrechte oder geneigte Bewehrungsbügel oder Bolzensysteme mit auf Stahlleisten aufgeschweißten Kopfbolzen oder mit Einzelbolzen mit aufgestauchten Köpfen einzubauen. Der Einbau dieser Systeme erfordert einen hohen Aufwand. Ferner ist es bekannt, die Durchstanzbewehrung durch mit Zwischenabständen achsparallel eingelegte Gitterträger zu bilden, die einfach eingebaut werden können und ein ausreichendes Verankerungsverhalten zeigen. Allerdings ist die Lasterhöhung beim Durchstanzversagen der Stahlbetonplatten gegenüber Bolzensystemen geringer.According to reprint " Element ceilings in the punching area of flat ceilings "of the magazine" Betonwerk + Fertigteil-Technik ", Issue 6/1997, pp. 96-104 , It is known to prevent the puncture failure in point-based flat slabs to install in the support area vertical or inclined reinforcing bracket or bolt systems with welded on steel bars head bolts or with individual bolts with upset heads. The installation of these systems requires a lot of effort. Furthermore, it is known to form the punching shear through with intermediate distances axially parallel lattice girder, which can be easily installed and show sufficient anchoring behavior. However, the load increase in the punching failure of reinforced concrete slabs compared to bolt systems is lower.

In einer aus DE-U 299 03 114 bekannten Durchstanzbewehrung werden Gitterträger mit Diagonalstrebenschlangen vorgesehen, in welchen die Biegungen der Diagonalstrebenschlangen exakt mit den Gurten abschließen. Zusätzlich sind Doppelkopf-Querbolzen in Schräglagen mit den Gurten fest verbunden, z.B. verschweißt oder verrödelt.In one DE-U 299 03 114 known punching reinforcement lattice girders are provided with diagonal struts snakes, in which complete the bends of the diagonal struts snakes with the straps. In addition, double-head transverse pins are firmly connected in inclined positions with the straps, eg welded or knurled.

Aus DE-A 34 10 419 ist ein als Durchstanzbewehrung punktförmig belasteter Platten vorgesehenes Schubbewehrungselement bekannt, das die Form eines in mehreren Windungen spiralförmig gebogenen Gitterträgers aus einem Obergurt, einem Untergurt und einer die Gurte verbindenden Diagonalstrebenschlange hat. Die Windungen sind zumindest auf einer durch die Gurte definierten Oberfläche durch strahlenförmig divergierend angeordnete Stäbe kraftschlüssig miteinander verbunden und relativ zueinander fixiert. Die Biegungen der Diagonalstrebenschlange können über den zugehörigen Gurt überstehen und in je zwei Schweißknoten damit verbunden sein. Auf die Zuordnung angrenzender Bewehrungslagen wird im Detail nicht eingegangen.Out DE-A 34 10 419 For example, a shear reinforcement element provided as punctiform reinforcement for punctured reinforcement is known, which has the shape of a lattice girder bent spirally in several turns and comprising a top chord, a bottom chord and a diagonal strut coil connecting the straps. The windings are non-positively connected to each other at least on a surface defined by the straps by radially divergently arranged rods and fixed relative to each other. The bends of the diagonal strut snake can survive over the associated belt and be connected to it in two welding nodes. The allocation of adjacent reinforcement layers is not discussed in detail.

Der Erfindung liegt die Aufgabe zugrunde, eine Durchstanzbewehrung der letztgenannten Art zu schaffen, die unter Beibehalt des Vorteils des einfachen Einbaus eine ausreichende Lasterhöhung gegen Durchstanzversagen erbringt.The invention has for its object to provide a punching reinforcement of the latter type, while maintaining the advantage of ease of installation provides a sufficient load increase against puncture failure.

Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.

Die über den zugehörigen Gurt überstehenden Biegungen der Diagonalstrebenschlangen gewährleisten eine größtmögliche statische Nutzhöhe des Gitterträgers und einen unproblematischen Einbau der in diesem Bereich erforderlichen Bewehrungslagen, insbesondere der Plattenlängsbewehrung. Mit dem Überstand der Biegungen über den zugehörigen Gurt wird sozusagen weitgehend der für die dort einzubauende Bewehrungslage erforderliche Höhenraum genutzt, um die statische Nutzhöhe des Gitterträgers zu vergrößern und den Einbau der Bewehrungslage zu vereinfachen. Das Tragverhalten der Durchstanzbewehrung hängt weitgehend von der Steifigkeit der Verankerungselemente ab. Ein möglichst geringer Verankerungsschlupf ist erstrebenswert. Diese Forderung wird hier kombinatorisch durch zwei Maßnahmen erfüllt. Da pro Biegung zwei Schweißbereiche als Verankerungen im Beton wirken, ergeben sich pro zu verankerndem Stab ein Schweißbereich und eine vergrößerte wirksame Länge des zu verankernden Stabs, z.B. des Gurtes. Weiterhin ist die Verankerung des Stabes mit angeschweißtem Querstab und dahinterliegender Biegung besser als bei direkt am Stab liegender Biegung. Die optimierte statische Nutzhöhe des Gitterträgers erbringt eine nennenswerte Lasterhöhung gegen Durchstanzversagen. Dabei sind in der Bewehrungslage quer zum Gurt verlaufende Querstäbe direkt an den Gurt angelegt, und gegebenenfalls daran gesichert, oder indirekt, z.B., über Distanzelemente, an den Gurt angelegt und gesichert. Der Überstand der Biegungen über den Gurt sollte relativ exakt der Höhe der Bewehrungslage entsprechen Günstige statische Verhältnisse mit den in die Durchstanzbewehrung eingegliederten Gitterträgern ergeben sich, wenn die Biegungen beider Diagonalstrebenschlangen über den gemeinsamen Obergurt überstehen, um in der Flachdecke, die beispielsweise von unten punktgestützt ist, eine optimale statische Nutzhöhe innerhalb des für eine Bewehrung nutzbaren Bereiches der Deckendicke, beispielsweise in der Biegebewehrung, zu erzielen.The over the associated belt protruding bends of Diagonalstrebenschlangen ensure the greatest possible static effective height of the lattice girder and unproblematic installation of required in this area reinforcement layers, in particular the longitudinal plate reinforcement. With the supernatant of the bends over the associated belt, so to speak, the height required for the reinforcement layer to be installed there is largely used to increase the static effective height of the lattice girder and to simplify the installation of the reinforcement layer. The carrying behavior of the punching shear depends largely on the rigidity of the anchoring elements. The lowest possible anchoring slip is desirable. This requirement is combinatorially met by two measures. Since two weld areas act as anchors in the concrete per bend, a weld area and an increased effective length of the rod to be anchored, e.g. of the belt. Furthermore, the anchoring of the rod with welded crossbar and underlying bending better than lying directly on the rod bend. The optimized static effective height of the lattice girder provides a significant increase in load against puncture failure. In this case transverse bars running transversely to the belt are applied directly to the belt in the reinforcement layer, and possibly secured thereto, or indirectly and, for example, via spacer elements, attached to the belt and secured. The projection of the bends over the belt should correspond relatively exactly to the height of the reinforcement layer. Favorable static conditions with the lattice girders incorporated into the punching reinforcement arise when the bends of both diagonal strut coils project beyond the common upper girth to the flat slab which is point-supported, for example, from below to achieve an optimum static effective height within the area of the ceiling thickness usable for a reinforcement, for example in the bending reinforcement.

In Gurtrichtung verlaufende Stäbe der Bewehrungslage sollten neben dem Gurt auf Querstäben angeordnet sein.In the belt direction extending bars of the reinforcement layer should be arranged next to the belt on crossbars.

Sind bei der überstehenden Biegung zwei in Gurtrichtung beabstandete Schweißbereiche vorgesehen, dann werden die Stabilität des Gitterträgers erhöht und seine Verankerung im Beton verbessert.Are provided in the protruding bend two spaced in the belt direction welding areas, then the stability of the lattice girder are increased and its anchoring in the concrete improved.

Im Kern wird die vertikale statische Nutzhöhe des Gitterträgers durch die überstehenden Biegungen erhöht, und zwar um ein Ausmaß entsprechend der Höhe der in diesem Bereich vorliegenden Bewehrungslage. Angestrebt wird ein Überstand der Biegung entsprechend der Höhe der Bewehrungslage.In essence, the vertical static effective height of the lattice girder is increased by the protruding bends by an amount corresponding to the height of the reinforcement layer present in that area. The aim is a projection of the bend according to the height of the reinforcement layer.

Herstellungstechnisch ist es günstig, die überstehenden Biegungen jeweils mit einem im wesentlichen kontinuierlichen Biegungsverlauf auszubilden.Manufacturing technology, it is advantageous to form the protruding bends each with a substantially continuous bending curve.

Alternativ kann es zweckmäßig sein, jede überstehende Biegung aus zwei Bögen und einem dazwischenliegenden in etwa geraden Abschnitt herzustellen. Dann sind die Schweißbereiche mit den Gurten günstig weit in Gurtrichtung beabstandet, und bieten die Biegungen große Flächen zur Verzahnung mit dem Beton.Alternatively, it may be expedient to make each projecting bend from two sheets and an approximately straight section therebetween. Then the welding areas with the straps are conveniently spaced far in the belt direction, and provide the Bends large surfaces to interlock with the concrete.

Günstig wird durch die überstehenden Biegungen, die im Gitterträger oben und/oder unten vorgesehen sein können, die vertikale statische Nutzhöhe bis auf ca. 110 bis 140 % des gegebenen Hochabstandes zwischen den Ober- und Untergurten erhöht.Conveniently, the vertical static effective height is increased to about 110 to 140% of the given high distance between the upper and lower chords by the protruding bends, which may be provided in the lattice girder above and / or below.

In einer beispielsweise durch eine Säule S punktgestützten Flachdecke D, ist im durchstanzgefährdeten Bereich eine Durchstanzbewehrung F vorgesehen. Bei der Flachdecke D kann es sich um eine sogenannte Elementdecke (wie gezeigt) oder um eine Ortbetondecke (nicht gezeigt) handeln. Eine Durchstanzbewehrung F ist nicht nur bei Punktabstützung von unten erforderlich, sondern gegebenenfalls auch unter einer aufstehenden Säule oder im Anschlussbereich einer vertikalen unteren/oberen Wand bzw. in einem Eckenbereich.In a punctiform ceiling D, which is punctiform, for example, by means of a column S, a punching reinforcement F is provided in the area which is to be pierced. The flat ceiling D may be a so-called element ceiling (as shown) or an in-situ concrete floor (not shown). A punching reinforcement F is required not only for point support from below, but possibly also below an upright column or in the connection area of a vertical lower / upper wall or in a corner area.

Mit Baufugen 3 sind vier Elemente E um die Säule S verteilt. Die Baufugen 3 sind (Fig. 2) mit Ortbeton 7 ausgefüllt. Unterseitig ist wenigstens je ein mit einer Bewehrungslage B versehenes Element als Fertigbetonschicht 6 vorgesehen. Auf die Betonschichten 6 ist wenigstens eine untere Bewehrungslage BU aufgelegt, die z.B. aus Quer- und Längsstäben 1, 2 gebildet ist. Auf die untere Bewehrungslage BU oder die Bewehrungslage B in jeder Betonschicht 6 (in Fig. 2 links angedeutet) sind mit Zwischenabständen um die Säule S verteilt mehrere Gitterträger T gesetzt. Die Gitterträger T können wie gezeigt achsparallel oder in etwa radial (sternförmig) zum Abstützpunkt verlaufen (nicht gezeigt). Im Bereich der Säule S können die Gitterträger T ausgespart sein, wenn dort der Anschluss der Säule S von unten in die Flachdecke D eingreift (nicht gezeigt). Jeder Gitterträger besteht z.B. aus zwei Untergurten U1, U2, einem Obergurt O und zwei Diagonalstrebenschlangen A, die an den Gurten festgeschweißt sind und obere und untere Biegungen CO und CU aufweisen. Auf die Gitterträger T ist eine obere Bewehrungslage BO aufgelegt (Biegebewehrung), die beispielsweise aus Längs- und Querstäben 4, 5 gebildet oder eine Bewehrungsmatte ist. Die obere Bewehrungslage BO kann in üblicher Weise an den Gitterträgem fixiert sein.With Baufugen 3 four elements E are distributed around the column S. The construction plans 3 are ( Fig. 2 ) filled with in-situ concrete 7. On the underside at least one element provided with a reinforcement layer B is provided as a precast concrete layer 6. On the concrete layers 6 at least one lower reinforcement layer B U is placed, which is formed for example of transverse and longitudinal bars 1, 2. On the lower reinforcement layer B U or the reinforcement layer B in each concrete layer 6 (in Fig. 2 indicated on the left), a plurality of lattice girders T are placed at intermediate intervals around the column S. As shown, the lattice girders T may extend parallel to the axis or approximately radially (star-shaped) to the support point (not shown). In the region of the column S, the lattice girders T can be recessed, if there the connection of the column S engages from below in the flat ceiling D (not shown). Each lattice girder consists, for example, of two lower chords U 1 , U 2 , one upper chord O and two diagonal strut snares A, which are welded to the straps and have upper and lower bends C O and C U. On the lattice girders T is an upper reinforcement layer B O launched (bending reinforcement), which is formed for example of longitudinal and transverse bars 4, 5 or a reinforcing mat. The upper reinforcement layer B O can be fixed in the usual way to the trusses.

Um die statische Nutzhöhe H (Fig. 3) der Gitterträger im Vergleich zum Hochabstand X zwischen den Gurten so groß wie möglich zu gestalten, stehen die oberen Biegungen CO der Diagonalstrebenschlangen A über den Obergurt O über, und zwar mit einer Höhe h1 entsprechend der Höhe der oberen Bewehrungslage BO. Von der oberen Bewegungslage BO sind die Querstäbe 5 auf die Obergurte O aufgelegt und gegebenenfalls mit Bindedraht 18 oder auch Heftschweißungen (nicht gezeigt) fixiert, während die Längsstäbe 4 auf den Querstäben 5 angeordnet sind. Die oberen Konturen der überstehenden Biegungen CO schließen z.B. in etwa mit der Ebene der Längsstäbe 4 der oberen Bewehrungslage BO ab. Der Überstand könnte auch höher als gezeigt sein.To the static effective height H ( Fig. 3 ) make the lattice girder as large as possible compared to the high distance X between the straps, the upper bends C O of the diagonal struts A over the top flange O are over, with a height h1 corresponding to the height of the upper reinforcement layer B O. From the upper movement position B O , the cross bars 5 are placed on the upper chords O and optionally fixed with binding wire 18 or tack welds (not shown), while the longitudinal bars 4 are arranged on the transverse bars 5. The upper contours of the protruding bends C O close, for example, approximately with the plane of the longitudinal bars 4 of the upper reinforcement layer B O from. The supernatant could also be higher than shown.

Die statische Nutzhöhe H der Gitterträger beträgt bei einem Abstand X von ca. 180 mm zwischen den Gurten in etwa 200 bis 220 mm. Die Höhe der unteren Bewehrung BU ist mit h2 angedeutet und kann der Höhe h1 entsprechen. Die Untergurte U1, U2 können auf den Querstäben der unteren Bewehrung BU ruhen.The static effective height H of the lattice girders is at a distance X of about 180 mm between the straps in about 200 to 220 mm. The height of the lower reinforcement B U is indicated by h2 and may correspond to the height h1. The lower chords U 1 , U 2 can rest on the transverse bars of the lower reinforcement B U.

Jede untere Biegung CU ist mit einem Untergurt U1, U2 in mindestens einem Bereich 17 verschweißt, während jede obere, über den Obergurt O überstehende Biegung CO in zwei in Gurtrichtung beabstandeten Bereichen 16 mit dem Obergurt O verschweißt ist.Each lower bend C U is welded to a lower flange U 1 , U 2 in at least one region 17, while each upper, over the upper flange O protruding bend C O is welded in two spaced apart in the Gurtrichtung areas 16 with the top flange O.

Bei der Ausführungsform der Fig. 4 sind die oberen Biegungen CO ohne nennenswerten Überstand am Obergurt O in jeweils einem Bereich 17 festgeschweißt, während die unteren Biegungen CU nach unten über die Untergurte U1 und U2 um die Höhe h2 überstehen und in jeweils zwei Bereichen 16 damit verschweißt sind. Es entspricht der Überstand der unteren Biegungen CU in etwa der Höhe h2 der unteren Bewehrungslage BU. Die statische Stützhöhe H des Gitterträgers T ist hier nach unten vergrößert.In the embodiment of the Fig. 4 the upper bends C O are welded without any significant overhang on the top flange O in a respective region 17, while the bottom bends C U project down over the bottom straps U 1 and U 2 around the height h 2 and are welded in two regions 16 therewith. It corresponds to the projection of the lower bends C U in about the height h2 of the lower reinforcement layer B U. The static support height H of the lattice girder T is increased down here.

In Fig. 5 lässt sich bei gegebenem Hochabstand zwischen den Gurten eine noch größere statische Stützhöhe H erzielen, indem sowohl die oberen als auch die unteren Biegungen CO, CU der Diagonalstrebenschlangen A über den jeweiligen Gurt überstehen und in die Bewehrungslage BO bzw. BU eindringen. Jede Biegung CO und CU ist in zwei Bereichen 16 mit dem zugehörigen Gurt O, U1, U2 verschweißt.In Fig. 5 can be at a given high distance between the straps achieve an even greater static support height H by both the upper and the lower bends C O , C U of the diagonal struts A over the respective belt and penetrate into the reinforcement layer B O and B U. Each bend C O and C U is welded in two areas 16 with the associated belt O, U1, U2.

Jede Biegung CO, CU kann entweder mit einem in etwa gleichmäßigen Biegungsverlauf 12 geformt sein, oder (wie in Fig. 5 alternativ gezeigt) mit zwei in Gurtrichtung beabstandeten Bögen 13, 14 und einem dazwischenliegenden, im wesentlichen geraden Bereich. Im letztgenannten Fall kann der in Gurtrichtung gesehene Abstand zwischen den Schweißbereichen 16 vergrößert und auch die zur Verankerung mit dem Beton nutzbare Oberfläche der Biegung unterhalb (bzw. oberhalb) des zugehörigen Gurts vergrößert sein. Es wäre denkbar, nur die Biegungen einer Diagonalstrebenschlange A überstehen zu lassen.Each bend C O , C U can either be formed with an approximately uniform bend profile 12, or (as in FIG Fig. 5 alternatively shown) with two straps 13, 14 spaced apart in the belt direction and an intermediate, substantially straight region. In the latter case, the distance seen in the belt direction between the welding regions 16 can be increased and also the surface of the bend which can be used for anchoring to the concrete below (or above) the associated belt can be enlarged. It would be conceivable to let only the bends of a diagonal strut A survive.

Sollte die untere und/oder obere Bewehrungslage aus nur einer Stablage oder aus mehr als zwei Stablagen oder Matten bestehen, sollte der Überstand der zur Vergrößerung der statischen Stützhöhe H über den zugehörigen Gurt hinaus geführten Biegung der Diagonalstrebenschlange zweckmäßigerweise der Höhe dieser Bewehrungslage entsprechen, um die optimale Stützhöhe H zu erzielen. Dies könnte auch der Fall sein, falls zwischen die Längs- und Querstäbe der Bewehrungslage Distanzelemente gesetzt sein sollten.Should the lower and / or upper reinforcement layer consist of only one stablage or of more than two staves or mats, the projection of the bending of the diagonal brace snake guided to increase the static support height H beyond the associated belt should expediently correspond to the height of this reinforcement layer optimal support height H to achieve. This could also be the case if spacer elements should be set between the longitudinal and transverse bars of the reinforcement layer.

Flat slab floor (D), in particular point-supported element floor or in-situ concrete floor, having a punching shear reinforcement which includes a plurality of lattice girders (T) which are arranged adjacent to at least one reinforcement layer (Bu, Bo), each lattice girder (T) having at least two spaced bottom booms (U1, U2), at least one top boom (O) and sinuous diagonal braces (A) positioned in a rooflike manner and firmly welded in the region of their bends (C) to the booms, characterised in that the bends (Co, Cu) of at least one sinuous diagonal brace (A) project beyond at least one boom (O, U1, U2) in the vertical direction of the lattice girder (T) by relatively precisely the height (h1, h2) of the reinforcement layer (Bo, Bu) or higher and penetrate into the reinforcement layer (Bu, Bo) in order to increase the static useful height (H) of the lattice girder (T), and in that transverse bars (1; 5; 10) running transversely to the boom (O, U) in the reinforcement layer (Bu, Bo) are laid directly or indirectly against the boom.
  2. Flat slab floor according to Claim 1, characterised in that the bends (Co) of both sinuous diagonal braces project beyond the top boom (0) in the lattice girder (T).
  3. Flat slab floor according to Claim 1, characterised in that longitudinal bars (4) of the reinforcement layer which lie approximately in the boom direction are arranged on the transverse bars at the side facing away from the boom.
  4. Flat slab floor according to Claim 1 or 2, characterised in that each projecting bend (C, Co, Cu) is welded to the boom in two regions (16) spaced in the boom direction.
  5. Flat slab floor according to Claim 1, characterised in that the vertical static useful height (H) of the lattice girder (T) is increased by at least bends (Co) of the sinuous diagonal braces (A) projecting beyond the top boom (O).
  6. Flat slab floor according to Claim 1, characterised in that the anchorage of the diagonal braces of the sinuous diagonal braces (A) in the concrete is a welded-on boom with projecting bend.
  7. Flat slab floor according to Claim 1, characterised in that the bend (Co, Cu) of the sinuous diagonal brace (A) projecting beyond the boom is designed with a substantially continuous bend course (12).
  8. Flat slab floor according to Claim 1, characterised in that the bend (Co, Cu) projecting beyond the boom comprises two curves (13, 14) and an approximately straight section (15) lying therebetween.
  9. Flat slab floor according to at least one of Claims 1 to 8, characterised in that, for a given vertical spacing (X) between the top and bottom booms, the vertical static useful height (H) of the lattice girder (T) is between about 110 and 140% of X, preferably between about 115 and 133% of X.
