Definitions

  • the present invention relates to an anti-fall safety structure for formwork with load-bearing panels for floor slabs.
  • the structure has the purpose of building a vertical barrier to be applied to formwork systems in order to create suitable operating conditions during the assembly of said structure.
  • formwork systems for floor slabs can be composed of elements such as vertical supporting props, supporting heads to be applied to the upper end thereof and load-bearing formwork panels which are mounted directly on the supporting heads.
  • a further drawback of systems of this type known so far is constituted by the fact that they can be assembled to the floor slab formwork system by virtue of mechanisms which are often complicated and awkward from the practical point of view, which slows the operations for installation of these systems at the building site, consequently entailing an extension of building times and therefore of the costs for the building company in addition to increasing the risk from the point of view of correct installation and thus compromising the level of safety ensured to workers.
  • the aim of the present invention is to provide an anti-fall safety structure for formwork with load-bearing panels for floor slabs that has a reduced space occupation and weight and can be handled not necessarily with mechanical lifting means.
  • An important object of the present invention is to provide an anti-fall safety structure that is very simple and can be managed with mechanisms that are easy to handle.
  • a further object of the present invention is to provide a safety structure that allows to perform multiple applications, specifically to provide a vertical protection that is complete, allows to protect any side of the formwork system with load-bearing panels and therefore renders work safe for workers in every respect.
  • an anti-fall safety structure for formwork with load-bearing panels for floor slabs is generally designated by the reference numeral 10 in a first embodiment thereof.
  • the safety structure 10 comprises:
  • Figure 3 shows by way of example a post supporting bracket 22, the other post supporting bracket 18 being understood to be identical.
  • the post supporting bracket 22 comprises, with respect to a configuration for use, a load-bearing longitudinal element 24, constituted for example by a tube with quadrangular cross-section 25 from which a coupling tube 26, for example having a round cross-section, for a post 15 and 16, protrudes upward.
  • a load-bearing longitudinal element 24 constituted for example by a tube with quadrangular cross-section 25 from which a coupling tube 26, for example having a round cross-section, for a post 15 and 16, protrudes upward.
  • the clamp means 19 are fixed on the load-bearing longitudinal element 24.
  • the clamp means 19 comprise
  • the resting plate 27 is designed to rest against the lower part 30 of a lateral transverse element 20, while the wedge-type closure system 21 acts against the upper surface 31 of the lateral transverse element 20, as shown in Figure 6 .
  • the load-bearing panel 11 is provided with lower reinforcement bars 35, arranged below and transversely to the transverse elements 14 and 20, and the resting plate 27 is provided in an upper region with two centering elements 29 adapted to arrange themselves at the sides of a reinforcement bar 35, as shown in Figure 6 ; the centering elements 29 can be constituted by two tubular segments having the sectional height of the reinforcement bar 35.
  • the wedge-type closure system 21 comprises a tubular guiding body 32, constituted for example by a tubular segment having a quadrangular cross-section and a vertical axis in the configuration for use, and a translation slider 33, clearly visible in Figure 5 , arranged so as to slide vertically in the tubular guiding body 32.
  • the translation slider 33 constituted for example by a tubular segment having a quadrangular cross-section, supports at the upper end a grip plate 36, which is adapted to be pressed against the upper surface 31 of the lateral transverse element 20.
  • the downward movement of the translation slider 33 is provided by means of a wedge-shaped body 34, clearly visible in Figures 3 and 4 , inserted in a transverse direction with respect to the vertical direction of translation of the slider 33, the wedge-shaped body 34 being inserted in corresponding through openings formed respectively in the guiding body 32 and in the slider 33.
  • the inclined side of the wedge-shaped body 34 acts by pushing against a corresponding edge or rim 37 of the through opening 38 in the translation slider 33, while the opposite horizontal side of the wedge-shaped body 34 rests against the upper edge or rim 39 of the through opening 40 in the guiding body 32.
  • the wedge-shaped body 34 is in a partially extracted configuration and the translation slider 33 is in a free configuration and can be lifted manually during engagement of the post supporting bracket 22 with a lateral transverse element 20; when the bracket 22 is positioned correctly on the transverse element 20, as shown in Figure 6 , striking the wedge-shaped body 34 pushes the slider 33, with the grip plate 36, against the upper surface 31 of the lateral transverse element 20, causing the closure of the clamp means 19.
  • the coupling tube 26 is engaged in the post 15 and 16.
  • the post 15 by way of example, is shown in Figure 9 , it being understood that the other posts 16 are identical.
  • the post 15 comprises, in the example described herein, a tubular body 45; the tubular body 45, for example having a quadrangular cross-section, is provided on a first side with a lower resting brace 46 for a net or grid 17, or other similar anti-fall protection element, and on a second side with three L-shaped braces, respectively 47, 48 and 49, which are fixed so as to be spaced in a vertical direction, each cooperating with a symmetrical L-shaped brace of another post 16 to the support of an anti-fall board 117, 117a and 117b, as shown in Figure 1 .
  • An anti-fall grid 17 is provided with a vertical central mesh 55, a lower inclined flap 56, for resting on the brace 46, and an upper inclined flap 57, for engagement with the engagement protrusions 53 of the various posts 15 and 16.
  • a foot retention plate 50 is interposed between the grid 17 and the posts 15 and 16 and rests on the braces 46.
  • the posts, 115 and 116 in Figure 1 are identical to the posts 15 and 16.
  • the posts 115 and 116 are exemplified in Figure 1 as supporting anti-fall boards 117, 117a and 117b, by virtue of the different arrangement on the post supporting brackets 122 and 118 with respect to the arrangement of the identical posts 15 and 16 in the above described embodiment of the invention.
  • each post supporting bracket 122 and 118 for example the bracket 122 of Figures 7 and 8 , comprises, with respect to a configuration for use, a load-bearing longitudinal element 124, constituted for example by a tube with quadrangular cross-section 125 from which a coupling tube 126, for example having a round cross-section, for a post 115 and 116, protrudes upward.
  • a load-bearing longitudinal element 124 constituted for example by a tube with quadrangular cross-section 125 from which a coupling tube 126, for example having a round cross-section, for a post 115 and 116, protrudes upward.
  • the further clamp means 119 are fixed on the load-bearing longitudinal element 124.
  • the further clamp means 119 are adapted to act by closure in a vertical direction as in the first embodiment of the invention.
  • the further clamp means 119 comprise:
  • the wedge-type closure system 121 comprises a tubular guiding body which is constituted for example by the same tube with quadrangular cross-section 125 of the load-bearing longitudinal element 124, having a vertical axis in the configuration for use, and a translation slider 133, arranged so as to slide on the quadrangular tube 125.
  • the translation slider 133 constituted for example by a tubular segment having a quadrangular cross-section, supports at the upper end the second plate-like body 163.
  • the second plate-like body 163 is supported by two bars 164 for connection to the slider 133.
  • the first plate-like body 127 is constituted, for example, by a metallic plate.
  • the slider 133 also bears a spacer 165 adapted to rest against the external vertical surface 166 of the lateral longitudinal profile 12.
  • the movement of the translation slider 133 is provided by means of a wedge-shaped body 134, inserted in a transverse direction with respect to the direction of translation of the slider 133, the wedge-shaped body 134 being inserted in corresponding through openings formed respectively in the guiding body, i.e., the quadrangular tube 125, and in the slider 133, in a manner similar to what has been described above for the previous embodiment of the invention.
  • the invention provides an anti-fall safety structure with reduced bulk and weight, which can be moved not necessarily with mechanical lifting means, since the post supporting brackets, the posts and the anti-fall grids or boards are all components that can be managed easily by a single operator or at the most by two operators, without the need to resort to particular lifting means.
  • the invention provides a safety structure that is very simple and can be managed with mechanisms that are easy to handle, by virtue of the wedge-type closure system of the clamp means, which can be managed easily with adapted hammers or sledgehammers.
  • the invention provides a safety structure that allows to provide a vertical protection that is complete, i.e., allows to protect any side of a formwork system comprising load-bearing panels, and therefore without load-bearing beams, and which therefore renders work safe for workers in every respect, since it can be provided with post supporting brackets that are suitable for fixing to a frame profile of a formwork panel.
  • the components and materials used may be any according to the requirements and the state of the art.
