  • Formwork units are known which are constituted by a series of panels of different width, assembled and installed to provide vertical concrete castings such as continuous walls, individual pillars, partitions, enclosed stairwells, and the like.
  • Known formwork systems are usually composed of a metallic supporting frame, to which a panel made of wood or other material (plastic, compacted wood, et cetera) is fixed, ensuring the provision of a planar and uniform concrete surface.
  • Conventional formwork units comprise panels with a steel frame to which an element, made for example of wood, is applied in the part affected by the concrete casting.
  • each type of object to be provided be it continuous vertical walls, pillars, corners between continuous vertical walls, requires the use of various panels, each of which has particular characteristics.
  • the provision of some objects by means of vertical concrete castings and formwork units of the background art requires further solutions.
  • the aim of the present invention is to overcome the limitations of the background art noted above, by proposing a formwork that is versatile and capable of providing various concrete objects efficiently.
  • an object of the present invention is to provide a formwork that does not require the use of additional wood compensation elements with respect to the panel made of wood or other material (plastic, compacted wood, et cetera).
  • a further object of the invention is to provide structures that can be assembled and are modular, so as to allow to provide various objects that require a vertical casting by modifying only the arrangement of the formwork units and without altering their shape.
  • Another object of the present invention is to require the use of components that are easily commercially available.
  • Another object of the present invention is to have a structure that is simple, relatively easy to provide in practice, safe in use, effective in operation, and relatively modest in cost.
  • the formwork of the present invention is easy to handle, lightweight and strong, and allows to provide in a versatile manner various types of object as a function of the manner in which it is assembled to another formwork unit of the present invention.
  • the formwork allows to ensure, for the space delimited inside it, a hermetic protection from the concrete casting.
  • the dimensions of the formwork can vary.
  • a formwork for vertical castings according to the invention is generally designated by the reference numeral 10.
  • the formwork for vertical castings comprises a closed and continuous perimetric structure or a metallic framework that comprises two posts 11, 12 constituted by longitudinal metallic profiles, to the ends of which cross-beams 13, 14 are connected which are constituted by metallic profiles that are perpendicular with respect to the posts.
  • the framework further comprises a plurality of additional metallic profiles.
  • Said framework is reinforced by metallic profiles 15, 16, 17, 18 which are transverse with respect to the posts and have a cross-section "C" (hereinafter referenced as C-shaped profiles for the sake of simplicity) and by metallic profiles 19, 20, 21, 22 which are transverse to the posts (hereinafter termed closed profiles), which are arranged parallel to the cross-beams 13, 14.
  • Additional reinforcement profiles 23, 24, 25, 26, which preferably have a flattened shape, are arranged at the vertical ends of the formwork for vertical castings according to the invention and in particular between the cross-beams 13, 14 and the respective C-shaped profiles that are directly adjacent thereto, i.e., the profiles 15 and 18.
  • the reinforcement profiles 23, 24, 25, 26 are arranged so as to mutually connect the cross-beams 13, 14 to the C-shaped profiles.
  • a sheet 27, made of plywood or other material, is applied to the metallic frame formed by the elements listed above, so that the surface of the formwork for vertical castings 10 according to the invention has a surface in contact with the concrete casting that is planar and uniform.
  • the plywood sheet 27 is fixed to the frame in various manners, which can be for example by means of screws that pass through the sheet and pierce the frame in the perimetric metallic profiles 11, 12, 13, 14 or in the transverse profiles 19, 20, 21, 22, 23.
  • the metallic profiles that compose the perimeter of the formwork for vertical castings 10 according to the invention or the two longitudinal metallic profiles 11, 12 and the cross-beams 13, 14 are composed of a cross-section, shown in Figure 3 , which has two concave regions 28, 29 separated by a central convex region 30. In the upper part of the profile there is a protrusion 31 that is adapted to form a perimetric containment edge for the sheet 27.
  • the two posts 11, 12 have holes 33 applied in the central region 32 of the profile which are adapted for the passage of accessories that are needed to mutually connect the panels and smaller holes 34 applied to the ends of said profile.
  • the two cross-beams 13, 14 are provided with holes 35 formed in the central region of the profile and adapted for the passage of accessories that are needed for the connection between formwork units.
  • the C-shaped transverse metallic profiles 15, 16, 17, 18 have openings 36, 37 in the continuous central part 38 and at the ends thereof in a symmetrical position. Holes 39 are provided centrally in the continuous central part 38 and are arranged at an appropriate center distance. Openings 36 and 37 and holes 39 are termed "front slots".
  • the C-shaped transverse metallic profiles 15, 16, 17, 18 are provided with one or more stiffening plates 40 which are arranged transversely with respect to the direction of longitudinal extension of the profile.
  • In the plywood sheet 27 there are holes 41, 42 arranged at the ends and holes 43 arranged in the central part, so that when the sheet is assembled to the framework the holes 41, 42 and 43 coincide perfectly with the slots 36, 37 and the circular holes 39.
  • the closed transverse metallic profiles 19, 20, 21, 22 are provided with holes 44 in an appropriate number, arranged at an equally appropriate center distance and applied on the sides 45 of the profile that are horizontal in the configuration for use.
  • a steel bush 46 which has the function of stiffening the passage formed by the holes 44.
  • Such passage formed by the holes 44 has the function of creating provisions for complementary accessories (such as service shelves, connection devices, stiffening breams, etc.) to be applied to the formwork.
  • the vertical profiles 23, 24, 25, 26 have the function of stiffening the ends of the formwork and are composed of appropriately shaped metallic plates, inside which there are holes 47 in an appropriate number and with appropriate dimensions or there are wider openings 48 adapted for the movement of the panels.
  • Plugs 49 made of preferably plastic material are applied to the sheet 27.
  • the holes at the ends 41, 42 and the holes 43 of the central part are in fact used for the passage of the tension members, preferably made of steel, which, when applied to the system, allow its stability.
  • the position of said plugs can be changed so as to allow at the same time a different arrangement of the tension members and therefore allow a large number of assembly combinations.
  • the described formwork is a fundamental unit, which, when assembled with other formwork units, allows to provide assemblies that allow to provide different concrete objects. Assembly can be provided by using various known auxiliary devices, such as clamps, brackets, tension members of various kinds, plates of a different kind, shoring elements, pins, screws.
  • the assembly of a series composed of individual formwork units in order to provide continuous walls, as in Figure 22 occurs by using some elements that belong to the background art, such as threaded metallic bars of tension members 50, metal locking plates 51, alignment clamps 52, closing plugs 53 and respective wedges 54.
  • the assembly between the formwork units 10 that are adjacent and compose a first formwork wall 55 occurs by means of alignment clamps 52, closing plugs 53 and respective wedges 54 in the number and combination deemed most appropriate.
  • the threaded metallic bars of tension members 50 in this particular configuration being described are arranged through the holes at the ends 41, 42, but the overall system does not exclude the possibility to utilize for this purpose, in some applications, the holes in the central part 43.
  • locking pins 56 and metal locking plates 51 omitting here some equipment that is often used for installation and that has just been described, such as for example building cranes, shoring elements, service ladders, scaffolding etc.
  • the mutual assembly of formwork units 10 occurs by placing the locking pin 56 within the C-shaped transverse metallic profiles 15, 16, 17, 18 so that the first element can slide within the second one until it encounters the two posts 11, 12 and in particular the holes 33.
  • the number of pins can vary depending on the height of the formwork panel, without having a preset number of elements.
  • a formwork unit according to the present invention and designated by the reference numeral 58 is connected to another formwork unit according to the present invention and designated by the reference numeral 59 in similar manners for the vertical casting of individual pillars, therefore by using locking pins 56 and metal locking plates 51.
  • the other elements that compose the assembly are connected in the same manner provided for the vertical casting of continuous walls by using elements that belong to the background art, such as threaded metallic bars of tension members 50, metal locking plates 51, alignment clamps 52, closing plugs 53 and respective wedges 54.
  • This assembly is delimited laterally by connecting a formwork unit 10 in the vertical position and arranged at right angles to the arrangement defined by the two assembled walls as described previously.
  • Head closure is performed therefore by using elements such as locking pins 56 and metal locking plates 51.
  • connection between the parallel continuous walls and the head panel that is perpendicular to them occurs by means of the connection system described previously for the provision of the individual pillar, i.e., by arranging the locking pin 56 inside the C-shaped transverse metal profiles 15, 16, 17, 18, in this case on both opposite panels that compose the parallel formwork planes, so that the first element can slide within the second element until it encounters the two posts 11, 12 and in particular the holes 33.
  • the number of pins can vary depending on the height of the formwork panel.
  • the application of metal locking plates 51, coupled to a locking pin 56 in the manner described previously for the provision of the individual pillar ensures adequate stability.
  • these formwork units 10 and 10a have all the characteristics and particularities provided and described previously, with the refinement of providing adapted connections for the accessories that are necessary for the installation of the formwork system.
  • the assembly in this case consists of formwork units 10 having a different vertical height, threaded metal bars of tension members 50, metal locking plates 51 and special formwork elements 57 which are contoured appropriately in order to obtain the shape that one wishes to give to the upper end (such as capitals, cornices, extra thick beams) made of concrete.
  • This special contoured formwork element is provided so as to provide for the connection of all of the accessories adapted to ensure the static stability and hydraulic tightness of the formwork.
  • the assembly of a series composed of formwork units 10 for the execution of vertical castings which provide for the provision of individual pillars with parts that protrude at the upper ends (such as capitals and cornices), as in Figure 29 , occurs by using formwork units for vertical castings 10 according to the invention which are arranged in a vertical position, as described previously for the provision of individual pillars.
  • the assembly of the system occurs by means of individual units of the invention of different height, for example lower ones 60 and taller ones 61.
  • the assembly in this case is composed of formwork units, designated by the reference numerals 60 and 61, which have a different vertical height, but are provided with an appropriate combination of the elements of the invention described so far, of threaded metallic bars of tension members 50, metal locking plates 51 and special formwork elements which are shaped appropriately so as to obtain the shape that one wishes to give to the upper end (such as capitals, cornices) made of concrete.
  • the system thus conceived allows to overcome the qualitative limitations of the background art.
  • the formwork according to the invention it is possible to obtain assemblies that allow to provide, following the execution of vertical concrete castings, different types of objects, such as continuous vertical walls, individual pillars, head closures, even with parts that protrude at the ends, such as capitals, cornices, extra thick beams.
  • the system according to the present invention allows to provide all the types of formwork required to provide the elements listed above with a single type of formwork unit, whereas currently a specific type is necessary for each one of the types listed above.
  • This simplification entails evident advantages which relate both to simplification of the provision of equipment required, gaining space, ease of assembly and, not least, economic saving. Furthermore, the present invention increases the level of safety of workers during work, due to the overall weight reduction, and therefore increases the maneuverability of the overall formwork system.
