Definitions

  • the present invention relates to a profiled anchor element structure for prefabricated concrete components.
  • metallic profiled anchor elements are used in the coupling and installation of prefabricated structural elements and can be either embedded preliminarily or in-situ in the prefabricated components or fixed thereto subsequently by means of screw anchors, special bolts, etc.
  • Said metallic profiled elements generally have a transverse cross section which is substantially C-shaped, with two wings which face one another and are joined by a base so as to define an anchoring seat which is usually used as an anchoring region for the head of bolts in couplings to be provided between the structural elements.
  • brackets are provided in order to increase cohesion between the concrete and the profiled element.
  • Said brackets which have various configurations, are associated with the profiled elements by welding or by providing holes on the base of the profiled element.
  • the perforations of the base of the profiled element produced inside the anchoring seat of the profiled element itself furthermore cause in any case a reduction in the profiled element resistance.
  • the aim of the present invention is to obviate the above described disadvantages by providing a profiled anchor element for prefabricated components with such a structure as to allow the profiled element to be embedded, with high resistance, to transverse loads even in the absence of brackets to improve its bonding.
  • an object of the invention is to provide a profiled anchor element which offers adequate assurances of strength even if it is embedded in low-thickness components.
  • Another object of the invention is to provide a profiled element which can in any case be provided with brackets to increase its bonding when embedded without necessarily requiring the welding of said brackets to the profiled element.
  • a further object of the invention is to provide a profiled anchor element which allows various arrangements of the anchoring brackets according to strength requirements.
  • a not least object of the invention is to provide a profiled anchor element which can be easily applied even on the outside of components without creating problems in the positioning of elements to be associated with the profiled element inside the anchoring seat defined by the profiled element itself.
  • a profiled anchor element structure for prefabricated concrete components which has, in transverse cross section, a substantially C-shaped configuration with two wings which face one another and are joined by a base defining an anchoring seat together with said two wings, characterized in that said base has, laterally to said wings, two extensions which define, outside said seat, a pair of additional fins for anchoring the profiled element.
  • the profiled anchor element having the structure according to the invention has a substantially C-shaped configuration in transverse cross section, with two wings 2a and 2b which face one another and are joined by a base 3 so as to internally define an anchoring seat 4.
  • the base 3 has, laterally to the wings 2a and 2b, two extensions which define, outside the seat 4, a pair of additional fins 5a and 5b which are used for a better anchoring of the profiled element to the component with which said profiled element must be associated.
  • the additional fins 5a and 5b are expediently obtained by pinching on the base 3 the ends of the wings 2a and 2b which connect to said base 3.
  • the profiled element according to the invention can be conveniently obtained by simple plastic bending of a metallic strip.
  • anchoring holes 6 are defined on the fins 5a and 5b and are elongated in the longitudinal direction of the profiled element; said holes can be used for example to allow the passage of concrete during embedding of the profiled element inside a component, so as to obtain excellent bonding between the profiled element and the concrete, or to associate anchoring brackets 7 of different shapes with the profiled element or again to fix the profiled element on the outside of already-made components, as will become apparent hereinafter.
  • the two wings 2a and 2b are arranged so as to converge on the opposite side with respect to the base 3.
  • the end portions of the free ends of the wings 2a and 2b are arranged so as to converge in the direction of the base 3, whereas in the second embodiment, illustrated in figure 2, said end portions are arranged in a plane which is substantially parallel to the plane of arrangement of the base 3.
  • the profiled element according to the invention can be embedded without problems in a concrete component during the casting thereof, keeping the open side of the anchoring seat 4 directed toward the outside of the component.
  • the widened base 3 with the additional fins 5a and 5b ensures an excellent anchoring of the profiled element in the concrete even without requiring the use of additional brackets. For this reason, the profiled element according to the invention can be easily used in low-thickness panels. In this case, the anchoring of the profiled element is ensured not only by the configuration of the profiled element itself but also by the presence of the holes 6 which connect the concrete from the lower side to the upper side of the profiled element.
  • brackets which can be simply constituted by appropriately bent metallic rods, either smooth or with improved bonding.
  • the brackets are associated with the profiled element by using the same holes 6 and can be orientated according to the requirements, as illustrated in detail in figures 3 to 14.
  • the profiled element according to the invention can also be applied on the outside of components by means of screw anchors 8 which are easily inserted through the holes 6, as illustrated in particular in figure 15.
  • the profiled element according to the invention has high strength with respect to conventional profiled elements.
  • the elements used for its anchoring to the component furthermore do not restrict at all the possibility of inserting in the seat 4 appropriate elements for mutually connecting the various components.
  • the profiled element according to the invention fully achieves the intended aim, since by virtue of its particular structure it can be anchored without problems to a wide range of components which may even have a low thickness.
  • the profiled element according to the invention by virtue of its characteristics of strength and high bonding to the concrete of the components, is furthermore particularly suitable for withstanding even seismic actions.
  • the materials employed, as well as the dimensions, may be any according to the requirements and to the state of the art.
