Definitions

  • Composite means for transmitting forces between the steel girder and the concrete slab in the case of composite girder structures consisting of steel, longitudinally welded to the girder of the girder and engage in the concrete of the slab are known, e.g. from US-A-3736 716.
  • composite materials made of flat bars with a rectangular cross-section, which are provided on one side with transverse ribs at close intervals and rest on the belt of the steel beam with the other, smooth side and are connected to this by fillet welds.
  • the welded flat bar creates a toothing in the contact surface between the concrete slab and the steel belt, through which shear forces can be transmitted in the longitudinal direction of the beam.
  • shear forces can be transmitted in the longitudinal direction of the beam.
  • lifting the slab additional reinforcement loops or headed dowels running in the direction of the slab thickness are required, which are welded onto the belt or flat bar and anchored in the concrete slab.
  • Head bolt dowels can also be anchored in a corresponding manner.
  • the transmission of the shear force takes place here by toothing, the concrete teeth engaging in the web holes of the U-profile from above.
  • larger aggregate grains can also sit in the center of the hole in front of the U-bar, which increases the shear strength in the horizontal shear surface in the upper edge of the U-bar.
  • the dowels or loops can only be installed at the construction site without welding and in a simple manner, they are still used by specially trained, i.e. reinforcement elements provided with thickening. Furthermore, the web parts of the U-profile that remain between the holes are subjected to bending in the vertical direction by anchoring the dowels or loops, which locally leads to larger hole spacings. In addition, it must be ensured that when concreting the slab, the cavity enclosed by the U-profile is properly filled with concrete. The disadvantage here is that dirt or water can easily accumulate in the cavity, which makes it difficult to produce perfect concrete quality in this highly stressed area. (The same naturally also applies to the concrete in the perforated area of the flat bar).
  • the invention is therefore based on the object to achieve the anchoring of the concrete slab without special loops or dowels and to increase the load-bearing capacity of the profiled bars as a compound and thus to make better use of them in economic and constructive terms.
  • the cross-sectional parts of the profile bars which generally protrude at right angles from the carrier belt, are provided with through holes at close intervals, the clear width of which is greater than the diameter of the largest grain of the concrete, and through the holes there is an existing concrete plate from the concrete Concrete dowel even more so.
  • the generally perpendicular, perforated cross-sectional parts also prevent the accumulation of dirt or water in the perforated area and ensure the production of perfect concrete at this point.
  • a very significant advantage of the design or arrangement of the profiled bars according to the invention is that shear forces can be transmitted in any direction via the concrete which penetrates through the holes in the profiled bar in a dowel manner, i.e. So also at right angles to the level of the belt surface so that the concrete slab is prevented from lifting from the steel belt from the outset.
  • FIGS. 1 to 4 The various design forms of the profile strips and the associated design options for producing the bond between the steel girder and the concrete slab are explained by way of example in the following FIGS. 1 to 4. Vertical sections through the bonded area are shown here at right angles to the beam span or, in the case of FIGS. 1b and 4b, also in the direction of the beam span.
  • Fig. 1 shows a profile bar 2 with a rectangular cross-section, which is welded with its narrow side by 2 fillet welds 4 in the longitudinal direction on the carrier belt 1.
  • the profile bar 2 (flat bar) has holes 3 in its cross-section part projecting from the belt at close intervals, as can be seen from FIG. 1b.
  • Bars of the lower transverse reinforcement of the reinforced concrete plate 6 are inserted through some of these holes, whereby the load-bearing capacity of the dowel is significantly increased.
  • a U-profile with flanges 7 projecting from the belt is welded onto the carrier belt 1 with the aid of the two fillet welds 4.
  • Holes 3 are made at close intervals in both flanges 7. This gives a multi-section dowel between the concrete slab and the carrier belt.
  • bow-like reinforcement bars 8 are inserted, which are anchored in the steel plate 6.
  • short steel bolts 5 can also be inserted through the holes, which fill the entire hole cross section and can be hooked into the stirrup-like reinforcing bars running in the longitudinal direction.
  • T-section is shown as a profile bar, which is welded with its flange on both sides by fillet welds 4 on the carrier belt and holes 3 are provided in the projecting web at close intervals.
  • T-profiles can be of advantage if the profile is deformed along the weld seams, e.g. can be avoided by punching holes.
  • the plate reinforcement is placed on the protruding web of the T-profile from above, so it does not engage in the holes.
  • the concrete slab is anchored to the belt by means of the dowel effect of the concrete in the perforated area by simple thin reinforcement bars 8 which are hooked into a part of the holes and perforated bars are used.
  • FIG. 4 again shows a profile bar 2 with a rectangular cross-section.
  • the large holes 3 which may be round or rectangular, smaller additional holes 9 are arranged. Through these smaller holes rods 5.
  • the reinforcement bars of the transverse slab reinforcement are pushed through and held at the height required for the concrete cover.
  • the bond is made on the one hand by the concrete dowels in the perforated area, and on the other hand by hook-like reinforcement bars that encompass the transverse reinforcement of the slab.
