Definitions

the present invention relates to an anti-lifting coupling system for the reversible joining of elements for providing a formwork for floor castings.
conventional formwork structures are constituted by a plurality of props that have, at their upper end, a head connected with various devices to the props, while the head in turn is connected to load-bearing beams that thus connect two successive heads.
Formwork panels are then laid on the upper end of such beams so that the system thus described has beams that form a line, and other beams that make up the system can belong to a line parallel to the first.
the panels that then define the horizontal plane of formwork represent a connection perpendicular to the directions formed by the parallel extension of two lines of beams formed by a corresponding number of groups of beams.
a first drawback of conventional formwork structures relates to the degree of safety of the elements that go to make it up in the assembly step, which are often assembled in a provisional manner with anti-lifting safety devices of the individual elements which can be improved in order to increase the overall level of safety during the assembly of the system.
a further drawback of conventional formwork structures arises when it is necessary to connect two portions of formwork surface that have directions of linear extension of the load-bearing beams which are mutually perpendicular, for example in huge-scale projects it often happens for reasons of geometry of the project that one area is laid according to a certain direction and an opposite area is laid in a direction perpendicular to the first. Since the surface of formworks must be continuous even if it is made up of macro portions of elements that make up frames with different directions, and perfectly planar and perfectly flat in order to perfectly connect two portions of formwork surface of the type just described, it is very often necessary to employ traditional technology as described above.
the aim of the present invention is to provide an anti-lifting coupling system for holding together two different elements that, used in different applications, contribute to creating individual elements which are able in their entirety to overcome the above mentioned drawbacks of conventional formwork systems.
an object of the present invention is to devise a system that allows greater versatility by also being adapted to formwork structures that are already known.
Another object of the invention is to devise a system that allows the simplification of many operations that are carried out on site in order to complete the steps of building the floor formwork, which are particularly long and costly.
Another object of the invention is to provide an anti-lifting coupling system for the reversible joining of elements for providing a formwork for floor castings which can be made using conventional systems and technologies.
an anti-lifting coupling system for the reversible joining of elements for providing a formwork for floor castings characterized in that it comprises:
an anti-lifting coupling system for the reversible joining of elements for providing a formwork for floor castings is generally designated in a first embodiment thereof with the reference numeral 10, as in Figures 3, 4 and 5 .
the anti-lifting coupling system 10 comprises:
the first engagement body 11 and the second engagement body 12 comprise reversible means of mutual engagement which are contoured to prevent the movement upwardly, in the configuration for use, of the second engagement body 12 with respect to the first engagement body 11.
the first engagement body 11 is constituted by two contoured plates 13 and 14, which are arranged mirror-symmetrical with respect to each other and are joined by a cylindrical crossmember 15, for coupling the second engagement body 12 as described in more detail hereinafter.
a recess 16 and 17 is defined on each one of the contoured plates 13 and 14 and is substantially U-shaped in profile, for inserting and resting a corresponding portion of the second engagement body 12.
the U-shaped profile of the recess has a flat bottom resting surface 18, two opposing inclined surfaces 19 for guiding the insertion, and a vertical portion 20, in the configuration for use, which acts as an anti-rotation abutment for a part of the second engagement body 12.
a reinforcement plate 21 and 22 respectively is fixed flush with the bottom 18 of each recess 16 and 17, and is also designed to increase the resting surface defined by each bottom 18.
contoured plates 13 and 14 also have upper inclined hook-shaped appendages 23 and 24, bent outwardly, upward from below in the configuration for use, with respect to the overall configuration of the first engagement body 11.
the second engagement body 12 is constituted by a central flat portion 26, horizontal in the configuration for use, which by way of two protrusions 27 interlocks onto two opposite symmetrical vertical reinforcement lateral flat portions 28.
the vertical flat portions 28 are connected by their opposite ends, i.e. opposite with respect to their ends to which the central flat portion 26 is applied, with a vertical supporting plate 29, which is adapted to be inserted into the recesses 16 and 17 of the contoured plates 13 and 14 of the first engagement body 11, and to be rested on the bottom 18 of each recess 16 and 17.
the vertical supporting plate 29 is longer than the distance between the bottom 18 of a first recess 16 and the corresponding bottom 18 of the other, second recess 17.
the vertical supporting plate 29 is rectangular.
An anti-rotation abutment element 30 is fixed in the upper part of the supporting plate 29, and is constituted for example by a cylindrical bar with a horizontal axis with respect to the configuration for use.
a hook-shaped portion 31 is fixed below the central flat portion 26 and is adapted to engage with the cylindrical crossmember 15 of the first engagement body 11.
the hook-shaped portion 31 occupies a position that lies on the vertical plane of symmetry of the second engagement body 12 with the concavity of the hook-shaped portion directed in the opposite direction with respect to the part of space occupied by the supporting plate 29 and by the abutment element 30.
Figure 4 shows the configuration of mutual coupling of the first engagement body 11 and of the second engagement body 12, with the second engagement body 12 inserted into the space 25 defined by the first engagement body 11.
the cylindrical crossmember 15 of the first engagement body 11 is inserted into the concavity of the hook-shaped portion 31 of the second engagement body 12, and at the same time the supporting plate 29 of the second engagement body 12 is inserted into the recesses 16 and 17 of the first engagement body 11, and is resting on each one of the bottoms 18 of the recesses 16 and 17; the thickness 33 of the supporting plate 29 and the transverse dimension 34 of the abutment element 30 are such that the abutment element 30 will rest against the surfaces of the vertical anti-rotation abutment portions 20 of the recesses 16 and 17.
the second engagement body 12 is prevented from making any movement upwardly, with respect to a configuration for use, thanks to the coupling between the hook-shaped portion 31 and the cylindrical crossmember 15, and thanks to the resting of the abutment element 30 against the vertical abutment portions 20 of the recesses 16 and 17, which prevents the second engagement body 12 from rotating in the direction of coupling beyond the position of mutual contact established; the only rotation permitted is the rotation for uncoupling, about the axis of the cylindrical crossmember 15, in the direction of departure of the abutment element 30 from the vertical abutment portions 20 of the recesses 16 and 17.
the system of coupling 10 solves the problems of unwanted lifting of an engagement body with respect to another engagement body that is coupled thereto, typical of conventional systems and implemented by way of simple coupling of a hook-shaped portion with a coupling element, such lifting being caused by an upward-acting vertical load, a usual situation during the assembly, disassembly and use of formwork structures for providing castings for floors.
the first engagement body 111 is constituted by two contoured plates 113 and 114, which are arranged mirror-symmetrical with respect to each other and are joined by a cylindrical crossmember 115, for coupling the second engagement body 112 as described in more detail hereinafter.

Two vertical plates 161 which are also perforated in order to allow the passage of nails in order to increase the stability of the system, extend in the upper part of the circular flat portion 158 and serve to locate the wooden beam 150.
the second engagement body 212 is constituted by a central flat portion 226, horizontal in the configuration for use, which by way of two protrusions 227 interlocks onto two opposite symmetrical vertical reinforcement lateral flat portions 228.
the vertical flat portions 228 are connected with a vertical supporting plate 229, which is adapted to be inserted into the recesses 216 and 217 of the contoured plates 213 and 214 of the first engagement body 211, described in more detail hereinafter, and to be rested on the bottom of each recess 216 and 217.
