Definitions

  • the present invention relates to a supporting device, of the falling head type, for supporting beams of formwork for floor slabs.
  • Supporting devices to be used in the provision of floor slabs which comprise a post to be fixed to the end of a supporting prop that rests on the ground and a supporting head for at least one supporting beam of a formwork panel, coupled along the post.
  • the supporting head comprises two plates which are arranged mirror-symmetrically and laterally adjacent to opposite sides of the post, in order to delimit a region for accommodating the ends of the supporting beams, and two symmetrical pairs of recesses provided on the plates, each for the insertion of an end portion of a supporting beam.
  • the aim of the present invention is to provide a supporting device of the falling head type that is capable of obviating the cited drawback, allowing the use of formwork panels of different thickness during the provision of a floor slab.
  • an object of the invention is to provide a supporting device that is structurally simple and resistant to loads.
  • a further object of the invention is to provide a supporting device of the falling head type for supporting beams of formwork for floor slabs that is easy to use.
  • Another object is to provide a supporting device of the falling head type for supporting beams of formwork for floor slabs that can be manufactured with known systems and technologies.
  • a supporting device for supporting beams of formwork for floor slabs, comprising a post, to be fixed to the end of a supporting prop rested on the ground, and a supporting head, coupled to said post, for at least one supporting beam of formwork for floor slabs, said supporting head comprising in turn:
  • the device according to the invention is generally designated by the reference numeral 10.
  • the device 10 comprises a post 11 to be fixed to the end of a supporting prop that rests on the ground (shown only in Figures 6 to 8 , where it is generally designated by the reference numeral 37).
  • the post 11 is tubular, with a square cross-section, and has a T-shaped portion 12 at its upper end.
  • a flat bracket 13 from which a shank 14 protrudes downward which is substantially aligned with the post 11, is to be inserted in the supporting prop 37 and is of the type conveniently provided with a complementary plate to which the flat bracket 13 is to be locked by bolting.
  • a supporting head 15 for two supporting beams 16 of formwork for floor slabs is coupled slidingly to the post 11.
  • Figure 1 shows only one supporting beam 16, while Figure 5 shows both.
  • the supporting head 15 comprises, on a base plate 17, two plates 18 that are welded thereto edgeways, are arranged mirror-symmetrically, are laterally adjacent to opposite sides of the post 11 and are adapted to delimit laterally two accommodation regions 19 for the ends of two contiguous supporting beams 16.
  • the base plate 17 is provided centrally with a through hole 20 (shown in broken lines in Figure 3 ) to allow sliding along the post 11; in particular, sliding is allowed along an initial portion 11a of the post 11 comprised between the flat bracket 13 and a pair of stroke limiters 21 arranged on opposite sides of the post 11, in an intermediate portion thereof.
  • Means 22 for reversible locking of the supporting head 15 at a preset position defined along the post 11 are associated with said head.
  • the supporting head 15 is also provided with two pairs of recesses 23 and 24, each for guiding insertion and containment for a resting portion 25 of the corresponding supporting beam 16, which are formed on opposite sides of the post 11.
  • Each recess 23a, 24a of each pair is provided on a respective plate 18 and mirror-symmetrically to the other recess 23b, 24b of the same pair provided on the other plate 18.
  • the two pairs of recesses 23 and 24 are provided with respect to each other at different heights, forming guides for the resting portions 25 of the respective supporting beams 16 to be installed at different heights from the ground.
  • each recess 23a, 23b, 24a, 24b forms at least part of the supporting surface of the resting portion 25 of the corresponding supporting beam 16.
  • the supporting surface of the resting portion 25 of a supporting beam 16 is formed by the bottom 26 of the respective recess 23a, 23b, 24a, 24b of each plate 18 and by the lateral edge 27 of a respective plate-like element 28, which is integrally laterally adjacent to the plate 18 so that the lateral edge 27 is substantially at the same height as the bottom 26 of the respective recess 23a, 23b, 24a, 24b.
  • a single plate-like element 28 is associated with each plate 18.
  • the plate-like element 28 is substantially L-shaped, as shown in Figure 2 , in which it is shown in broken lines (since otherwise it would not be visible in the front view because it is hidden by the plate 18), forming, with two portions of its lateral edge 27, a part of the supporting surface for the resting portions 25 of two supporting beams 16 to be arranged at different heights.
  • each supporting beam 16 is constituted by a flat element 29 at the end of said beam, which has laterally protruding parts.
  • the supporting head 15 is provided with safety abutment elements 30 for the end of the supporting beam 16 during the setup and removal of the supporting beam 16, which comprise hook-like portions 31 that extend, as a continuation of the upper portions of the recesses 23a, 23b, 24a, 24b, toward the outer and upper region of the plates 18.
  • the concavity of the hook-like portions 31 is oriented substantially toward the post 11.
  • the supporting head 15 further has two transverse elements 32 for connecting the two plates 18, on opposite sides of the post 11, which are adapted for the temporary resting of an inclined lower portion 33 of the supporting beams 16 during their setup and removal.
  • the transverse elements 32 substantially consist of cylindrical pivots welded at the ends to the two plates 18, conveniently at different heights.
  • the above cited reversible locking means 22 are of a known type and, as can be seen in Figure 4 , comprise a frame 34 that is provided centrally with a through cavity that is shaped substantially in two separate portions: a first portion (not visible), which is substantially equal to the length of the initial portion 11a of the post 11, and a second portion 35, which is larger than the plan dimensions of the cross-section of the initial portion 11a.
  • the post 11 has, on opposite sides, two wings 36 (shown in Figure 1 and in Figure 2 ), on the upper ends of which the first portion of the frame 34 rests slidingly.
  • the base plate 17 of the supporting head 15 rests on the frame 34; in this manner, said head is supported by the frame 34, which prevents its fall.
  • said frame can slide on the upper ends of the two wings 36 until the second portion 35 arrives thereat: the second portion 35 is wider than the post 11 with the wings 36 and therefore, since it cannot be supported by the wings 36, the frame 34 falls downward to the bracket 13, together with the supporting head 15.
  • two contiguous supporting beams 16 can be associated with a supporting head 15, as shown in the example of Figure 5 , at different heights from the ground, as a function of the height of the pairs of recesses 23 and 24.
  • Figures 6 to 8 show examples of use of the device 10 after the application of the formwork panels 38a, 38b, 38c, 38d.
  • Figure 6 shows formwork provided by applying a prefabricated metallic panel 38a to the highest supporting beam 16 and a metallic panel with a wooden surface 38b, thicker than the preceding one, to the lowest supporting beam 16.
  • Figure 7 shows formwork provided by applying a prefabricated metallic panel 38a to the highest supporting beam 16 and a wooden panel 38c, thicker than the preceding one, to the lowest supporting beam 16.
  • Figure 8 shows formwork provided by applying a wood panel 38d, of the same type as the above cited wood panel 38c but thinner, to the highest supporting beam 16 and a metallic panel with a wooden surface 38b, which is thicker than the preceding one, on the lowest supporting beam 16.
  • the device according to the invention in fact allows to use formwork panels of different thickness during the building of a single floor slab despite being at the same time structurally simple and resistant to loads.
  • the device is also easy to use and can be manufactured with known systems and technologies.
  • the materials used may be any according to the requirements and the state of the art.
