Definitions

  • the invention relates to a component for shear and / or punching shear reinforcement, in particular for transmitting power in the connection area of supports on reinforced components such as flat slabs and floor slabs, consisting of a plurality of preferably designed as a head bolt reinforcement elements which are mutually parallel and spaced from each other, and from one of the reinforcing elements mutually determining connecting element, wherein the connecting element consists of a rail with approximately U- or C-shaped cross-section, which engages with their profile edges, the terminal bolt heads of the head bolts and so determines the head bolts.
  • Such shear reinforcement elements are known for example from DE-A 195 48 685.
  • the existing of a sheet material rail overlaps the upper bolt heads, starting from the upper side of the side up to the frustoconical underside of the upper bolt heads.
  • the minimum concrete coverage which is the edge region of the component that is susceptible to corrosion and may be equipped only with corrosion-resistant materials
  • the minimum distance between the top of the armored component, ie in particular the flat ceiling, and the top of the rail defined must therefore the upper bending reinforcement for the component on which the rail is placed, according to the inside, so be moved away from the top of the reinforced component, including the static effective height of the component suffers accordingly.
  • the present invention seeks to further improve the component for shear and / or shear reinforcement of the type mentioned and in particular to increase its static effective height.
  • Another advantage of the rail is that the rail even take static functions and especially in the horizontal direction can forward the thrust forces or in terms of the truss-like force curve for a better force or force discharge in or out of the bolt head.
  • the existing concrete or plastic rail head bolts can be used advantageously to set up the entire component for shear reinforcement on the lower component formwork, so you do not need separate spacers, as described for example in said EP-A 1 033 454.
  • the rail is made of high strength or at least stronger concrete, e.g. from C50 or C60, which then ensures the appropriate takeover of the static tasks.
  • the concrete material is fiber-reinforced in order to achieve better tensile strength and thus overall better stability.
  • the rail is formed profiled at least on one of its outer long sides. As a result, the profile rail with the concrete an even better positive connection.
  • the head bolts in the rail either cohesively, for example by gluing, or are positively fixable.
  • the bolt heads of the head bolts may have a deviating from a circular circular horizontal cross-section, in particular an oval or a corresponding a hammer head shape horizontal cross-section.
  • the horizontal cross section of the bolt heads and the approximately U- or C-shaped vertical cross section of the rail can be coordinated so that the bolt heads with their narrower horizontal cross section - similar to a hammer head screw in so-called Halfen rails - in the groove of the rail between the profile edges can be inserted and that they are there by rotation around in particular about 90 ° about the bolt longitudinal axis under Schugreifung the profile edges in the groove of the rail, for example, by clamping or positive locking can be fixed.
  • FIG 1 and Figure 2 shows an inventive shear reinforcement element 1 is shown, which consists of a plurality of vertical to be mounted in the component to be braced head pin 2 and a head bolt mutually in the predetermined position and orientation to each other defining connecting element 3 exists.
  • the head bolts 2 consist of a cylindrical profiled stud shaft 4 with upper end bolt heads 5 and lower end bolt heads 6.
  • the connecting element 3 in turn has an approximately C-shaped vertical cross section to form a groove 7, in the upper bolt heads 5 of the head bolts 2 are inserted.
  • the connecting element 3 has for this purpose two groove 7 limiting profile edges 8, 9, which form the free mutually facing legs of the C-shaped cross-section and - as shown in particular in Figure 3 - embrace the upper bolt heads 5 and thus the head bolt 2 positively establish.
  • the head bolt 2 can be inserted with their bolt heads 5 in the groove to the groove bottom 10 and then be folded by 90 ° about the pin longitudinal axis 11, so that each bolt head protrudes with the wider diameter D2 in the lateral groove recesses of the profile edges 8, 9 and is thus encompassed by these profile edges.
  • the positive connection of the head bolt 2 is further improved with the connecting element 3.
  • FIG. 3 shows how an outer longitudinal side 12 of the profiled rail 3 profiled, that is to say in FIG. with horizontally extending grooves 13, is formed to improve the bond with the surrounding concrete of the reinforced component.
  • the present invention offers the advantage of providing a connecting element for a shear or punching reinforcement element which can extend into the minimum concrete cover.
  • the length of the head bolts can be increased so much that their static effective height is correspondingly improved.
  • the upper and lower bending reinforcement of the component to be reinforced can be moved all the way to the edge of the minimum concrete cover, in contrast to the profile rail consisting of sheet metal. This also makes it possible to improve the static effective height of the reinforcement once again.
