Definitions
- the invention relates to a point-based element or flat concrete pavement according to the preamble of patent claim 1.
- a point-based element or flat concrete pavement known from EP 1 070 800 B1 the upper and / or lower bends between the diagonal struts project beyond the continuous upper flange and / or the continuous lower flange in each lattice girder of the transverse force and punching reinforcement to form efficiently acting concrete anchoring zones in the ceiling.
- the diagonal brace snakes are regularly bent and each show a diagonal brace oriented at 90 ° to the straps and then a diagonal brace inclined at 45 ° to the straps, so that in the end region of a lattice girder tapering towards the brace the uppermost and diagonal braces upper and lower concrete anchoring zones are created leaves equidistant from the vertical column axis.
- lattice girders known from EP 2 050 887 B1 for transverse force and punching reinforcements of elemental or flat concrete slabs, a continuous upper girder is missing.
- successive anchor elements are provided, on which the upper bends of the diagonal strut coils are fixed.
- two adjacent diagonal struts are respectively shown in the same direction and inclined substantially parallel to each other at about 45 ° relative to the lower chords, so that the upper concrete anchoring zone is considerably longer in the longitudinal direction of the lattice girder than the lower concrete - Anchorage zone of the same diagonal strut is offset by a very large amount, which corresponds approximately to the lattice girder height.
- a lattice girder with two lower chords, a continuous upper chord and two diagonal strut slings is known, in each of which a diagonal strut inclined at 90 ° relative to the straps follows a diagonal strut inclined at 45 °.
- the concrete anchoring zones formed in the region of the fixing points of the diagonal brace inclined at 90 ° lie one above the other without displacement in the longitudinal direction of the girder girder.
- German general building inspector ate approvals, when using lattice girders as shear-through reinforcements depending on the lattice girder type, eg increments relative to slabs or punching reinforcement of 1, 25 (approval Z-15.1 -38), 1, 6 (approval Z-15.1 -289) and 1, 7 (Admission Z-15.1-217). These approvals are based on component tests on ceiling cut-outs. The ascertained increase factors are lower than in other known, traditional reinforcement systems, such as double headed bolts.
- the invention has for its object to provide a point-based element or flat concrete pavement with even better effectiveness of the reinforcement and larger increase factors against punching.
- This training is achieved not only by the special angle of at least the supporting next and the following diagonal struts, but can optionally be created by special cutting pre-fabricated lattice girder at different points in the longitudinal direction, or result from a combination of these structural measures.
- the lower concrete anchoring zone maintains a distance of only about 2.0 cm from the vertical projection of the support side surface, and / or the projection of the upper concrete anchoring zone over the lower concrete anchoring zone at least approximately the distance corresponds to the lower concrete anchoring zone of the vertical projection of the support side surface.
- the steeper angle of inclination of at least the nearest supporting diagonal strut should be between about 70 ° to 85 ° relative to the lower chords, while the shallow angle of inclination of at least the next offshore diagonal strut should be between 45 ° to 75 °.
- the steeper the angle of the supporting diagonal strut the steeper the angle of the diagonal strut away from the support, but in any case about 10 0 flatter than the steeper angle.
- the improved efficiency of the reinforcement and particular high increase factors can also be achieved if the surface of the diagonal brace and / or straps is ribbed. This results in an even better toothing with the concrete. Further, it is particularly important for the reversal of damage in the concrete pressure zone in the lower chords that the diameter of at least the lower chords is greater than the diameter of the diagonal strut snake.
- the diameter of the lower chords should be at least 10 mm, the diagonal struts then being e.g. have a diameter of about 9 mm.
- the projection of the upper concrete anchoring zone over the lower concrete anchoring zone of the nearest diagonal strut should be at least approximately equal to the distance of the lower concrete anchoring zone from the vertical projection of the support side surface plus a measure corresponding to at least one Part of the measure of a concrete cover of the reinforcement in the support corresponds.
- the element or flat concrete ceiling is made of prefabricated concrete slabs with a concrete layer, wherein the respective lattice girder is embedded in the concrete slab.
- the supernatant of the upper concrete anchoring zone of the supporting diagonal next strut should correspond relatively closely to the distance of an edge of the concrete slab from the vertical projection of the support side surface and / or at most the distance of the edge of the concrete slab from a near-edge reinforcement in the support.
- the supernatant should maximally correspond to approximately half the width of a joint between two adjacent concrete slabs.
- this should be prefabricated molded parts or pieces of chord, which protrude at both ends in the longitudinal direction of the lattice girder over the upper bends and thus contribute to the creation of each upper concrete anchoring zone. Further expedient embodiments are contained in subclaims.

- the lattice girder 1 has two straight, continuous and parallel lower chords U, two diagonal strut snakes D (alternatively and not shown only one diagonal strut snake) and a straight, continuous upper chord O.
- the cross-section of the lattice girder 1 is e.g. triangular.
- the diagonal strut coils D possibly covering in the side view are e.g.
- Each diagonal strut snake D is for example regularly bent so that substantially similar diagonal struts S1, S2 arise, which are connected to each other via upper and lower bends 1 1, 12 and inclined obliquely different from each other in the same direction upwards and towards one end of the lattice girder 1, which is shown in Fig. 1 right.
- This end region is assigned in the concrete floor BD (FIG. 5) to a support T of the point support of the ceiling, such that the diagonal struts S1, S2 are inclined in the same direction upwards and in the direction of the support vertical axis A.
- At least the next closest diagonal strut S1 (assuming that the truss girder 1 is tapered towards the strut with its indicated end portion) is inclined at an angle a1 to the under and upper girdles U, O towards the support T which is less than 90 ° and between about 70 ° to 85 °.
- the next following diagonal strut S2 is inclined in the same direction but at a shallower angle a2 relative to the straps O, U up to the support T, which is between about 45 ° and 75 °, but at least 10 ° flatter than the latter steeper angles a1.
- the surface of the diagonal strut snakes D and / or the straps U, O may still have a rib structure 9 or 8 for better anchoring in the concrete.
- upper or lower concrete anchoring zones VO, VU are formed either by the bends alone or with an anchor element 10 (FIGS. 11 and 12) or a projecting belt section 14, 13 and the fixing points SO, SU (welding points) ,

- the distance between the fixing points SO at the upper flange O and SU at the lower chord U is the supernatant UV, if (as a theoretical assumption) the upper concrete anchoring zone VO and the lower concrete anchoring zone VU are each the fixing point SO , SU of the diagonal strut S1 with the respective belt O, U applies.
- the diagonal strut combination with S1, S2 and ⁇ 1, a2 in the longitudinal direction of the lattice girder is repeated at least once again, preferably regularly over the entire lattice girder length.
- the diameters of the belts U, O and the diagonal struts D are highlighted with d1 and d2.
- the diameter d1 should be greater than the diameter d2, wherein, preferably, the diameter d1 of the lower chords U should be at least 10 mm and that of the diagonal strut snake D should be about 9 mm.
- a2 are provided for the diagonal struts S1, S2, as explained above.
- the upper bends 1 1 of the diagonal strut snakes D here terminate essentially flush with the upper side of the upper flange O.
- FIGS. 5 and 6 show a lattice girder 1 as part of a transverse force and punching resistance B of a concrete ceiling BD (element or flat ceiling) with assignment of the lattice girder.
- support 1 to the support T.
- the support T in the embodiment shown has a square cross section with side surfaces 3 and a vertical axis A, but could also have a rectangular cross section or a polygonal cross section or a circular cross section and (not shown) with a reinforcement (FIGS. 9 and 10 ).
- Similar lattice girders 1 could also be arranged in parallel and installed laterally and parallel to another support edge 3 and extend into the region of the support T or beyond.
- the lattice girder 1 runs perpendicular to the vertical projection of the support side surface 3 and substantially to the support vertical axis A.
- the distance AS of the upper concrete anchoring zone VO from the vertical projection of the support side surface 3 is smaller than the distance of the lower concrete anchoring zone VU of the support nearest diagonal strut S1 from the vertical projection of the support side surface 3.
- the clear distance AS is dimensioned.
- FIGS. 7 and 8 show a preferred embodiment of a concrete pavement BD.
- the upper concrete anchoring zone VO here concludes relatively accurately with the vertical projection of the support side surface 3.
- the distance AS is substantially equal to zero.
- the distance of the lower concrete anchoring zone VU from the vertical projection of the support side surface 3 corresponds to the projection UV, for example, of FIGS. 1 and 3.
- a dashed line 4 indicates the outer edge of a prefabricated concrete slab 6 into which the lattice girder 1 is embedded such that the lower concrete anchoring zone VU of the nearest diagonal strut S1 lies within the concrete slab 6.
- the supernatant UV can correspond to the distance between the edge 4 of the concrete slab 6 and the vertical projection of the support side surface 3.
- FIGS. 1 is preferably for a design of a reinforced concrete slab with prefabricated thin reinforced concrete slabs 6, in which the lower part of the punching reinforcement B has already been concreted, and with a distance (see the edge 4) for vertical projection the side surface 3 of the support T are installed. If the concrete slab 6 is placed on the support T or if the entire structure is produced without prefabricated concrete slabs, then the lower chord U of the lattice girder 1 can extend beyond the lower concrete anchoring zone VU to the vertical projection of the support side surface 3 or even further up to above Support T be performed.
- FIGS. 9 and 10 show a further embodiment in which the upper concrete anchoring zone VO of the supporting diagonal strut S1 of the lattice girder 1 lies above the support T, ie within the vertical projection of the support side surface 3.

- the upper concrete Anchoring zone VO of the nearest supporting diagonal strut S1 engages, in Figures 9 and 10, relatively precisely the amount of concrete cover 7 over the vertical projection of the support side surface towards the column vertical axis A and beyond the support T. This supernatant shown may be a maximum value of a preferred embodiment. ie the upper concrete anchoring zone VO should be placed within the vertical projection of the concrete cover 7.
- the supernatant UV should be limited to about half the joint width.
- the joint width is often 4 cm, but other joint widths are possible. Then the supernatant should be about 2.0 cm with a joint width of 4 cm.
- the design of the lattice girder in the punching shear reinforcement B effectively reinforces the concrete pressure zone of the concrete slab and thus prevents premature failure.
- the nominal yield strength of the reinforcement components used may preferably be 500 N / mm 2 .
- Further material properties correspond to those of conventional reinforcing bars. But also reinforcing bars with other and better material properties can be used.
- a combination of the novel lattice girder with other reinforcement elements and the same lattice girders with a different arrangement to the load introduction surface or support is possible, for example in a case in which further lattice girders are arranged parallel to the support edge or vertical projection of the support side surface 3.
- each anchor element 10 protrudes in the longitudinal direction of the lattice girder 1 via the bend 11, so that the upper concrete anchoring zone VO of the supporting diagonal strut S1 formed in the region of the weld point SO has the supernatant UV opposite the lower concrete anchoring zone VU on each lower chord U ,
- the lattice girder 1 in FIGS. 11 and 12 can be installed like the one based on the preceding embodiments of the concrete deck BD with respect to the support T of the point support.
