Definitions

  • the present finding regards a system comprising a beam, a corrugated trapezoidal sheet and a connector on said corrugated trapezoidal sheet.
  • a typical case of use of this kind of system is the one supporting a concrete slab.
  • the connector mainly exercises a resistance against the horizontal movement between the underlying beam and the slab. Furthermore, the connector is shaped in such a manner to resist against vertical detachment forces between the beam and the slab.
  • the steel beams are referred to as primary or secondary depending on their importance from a static point of view in the building industry.
  • the structure of the transverse section of these beams can be extremely varied and, strictly for exemplification purpose, only IPE or HE beams are mentioned hereinafter.
  • the beams are covered with a layer of concrete and thus there is the possibility of providing for reciprocal fastening between the beam and the concrete itself.
  • metal sheets of the so called trapezoidal corrugated type, given that they have alternating furrows and reliefs; in particular, it is provided for that the concrete be applied over the sheets, which thus end up interposed between the concrete and the beams.
  • trapezoidal corrugated sheets reciprocal fastening between the underlying steel beam and the concrete slab through the trapezoidal corrugated sheet is required.
  • EP-A-0 504 500 discloses a system according to the preamble of claim 1.
  • the objective of the present invention is to provide a system comprising a connector of the type described above, easier to mount and also more resistant once mounted, with respect to similar connectors of the known type.
  • the connector in said system is capable of adapting both to the presence of straight or U-shaped bars, for reinforcing the connection with the concrete, which will be arranged in proximity to the upper ends of said side edges, and also to the presence of possible ribs (usually referred to as bosses)at the bottom of the trapezoidal corrugated sheets.
  • the connector generally indicated by 100, has a substantially rectangular-shaped base 1, which is fastenable against a beam (possibly through an interposed sheet), through one or more studs 2 or other equivalent fixed connection elements. Rising from said base are two substantially flat-shaped side edges 3 arranged slanting with respect to the abovementioned base, in such a manner to widen moving from the base upwards.
  • some grooves 4 provided with a widened end 4', to allow the insertion of a metal rod 5 (see figures 6-10 ) inside the same, which will serve as a reinforcement element for the concrete; the insertion is conceived in a manner such that the rod cannot dislodge neither during the execution step, nor during the operation step when the connector exercises its resistance against the horizontal movement between the slab and the beam.
  • the connector subject of the finding shall be directly fastened against a trapezoidal corrugated sheet 7.
  • the trapezoidal corrugated sheet 7 is provided with a boss 8 at the bottom of its furrows and, to allow the fastening of the connector against the sheet, it is provided that the bottom 1 of the base be advantageously wavy 9, purposely for adapting to the corresponding boss of the trapezoidal corrugated sheet; additionally, advantageously provided at the inner surface of the connector is a reinforcement rib 10.
  • figures 11-14 show that the fastening of the base 1 to the trapezoidal corrugated sheet shall require at least one fastening point, through studs 2 or other connection means, though the best results shall be obtained by means of a pair of studs, as illustrated in fig. 11 .
  • the device subject of the present invention shall be advantageously used for direct connection between the concrete 11 and the beam 6; this system does not form part of the claimed invention.
  • reinforcement rids 5 Provided within the concrete are reinforcement rids 5.
  • Fig. 17 shows that the connector is used in a system, wherein a trapezoidal corrugated sheet 7 is provided and in this system the connector shall be fastened against the beam 6 passing through the trapezoidal corrugated sheet.
  • Figures 18-20 show that the connector is adapted to be applied to various shapes of a trapezoidal corrugated sheet 7; obviously the structure of the base 1 of the connector shall vary depending on the boss 8 if provided on said trapezoidal corrugated sheet.
