Definitions

the invention relates to a flat ceiling according to the preamble of claim 1.
a shear reinforcement element provided as punctiform reinforcement for punctured reinforcement 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.

EP 0 465 776 A WO89 / 00226A .
WO93 / 15287A DE 24 58 081 A and DE 12 69 324 B ,
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.
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.
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.
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.
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.
the construction plans 3 are ( Fig. 2 ) filled with in-situ concrete 7.
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.
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).
each lattice girder 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.
an upper reinforcement layer B O launched bending reinforcement
the upper reinforcement layer B O can be fixed in the usual way to the trusses.
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.
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.
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.
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 Gurtraum areas 16 with the top flange O.
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.
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.
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.
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.
