Definitions

  • the present invention relates to a clamp for formwork for vertical castings.
  • vertical casting systems used in the building sector are normally provided by formwork panels, anchoring tension members, closure plates and connecting clamps.
  • the concrete applies a thrust to the walls of the formwork that is balanced by the steel tension members.
  • the plates act as a stop element for the movement of the formwork along said tension members.
  • the clamps instead have the function of keeping the panels integral to each other, so that they constitute a single formwork surface.
  • clamps have the important task of maintaining the alignment between the panels, so that the formwork surface is perfectly flat and does not give rise to unwanted differences in level between the panels, which would also be reflected in the final concrete surface.
  • These clamps generally use the nearing and clamping movement of one or two movable jaws.
  • the aim of the present invention is to provide a clamp for formwork for vertical castings that overcomes the drawbacks of the cited background art.
  • a particular object of the invention is to provide a clamp that ensures effective locking and perfect positioning of the formwork panels both in terms of mutual alignment and in terms of adherence.
  • Another object of the invention is to provide a clamp that can be coupled to formwork panels in a simple and rapid manner without having to screw bolts and the like.
  • Another object of the invention is to provide a clamp that can be assembled easily and is strong and stable.
  • a further object of the invention is to provide a clamp the jaws of which apply the same clamping effect.
  • Another object of the invention is to provide a clamp that is highly reliable, relatively simple to provide and obtainable at competitive costs.

  • Figure 8 is a perspective view of an embodiment of formwork with the use of a pair of clamps according to the invention.
  • the clamp according to the invention designated generally by the reference numeral 1, comprises a first body 10 provided with a first jaw 12, which is designed to be coupled slidingly to a second body 20 which forms a second jaw 22.
  • the clamp 1 furthermore comprises locking means 30 which allow to mutually lock the first and second bodies 10, 20, so as to mutually clamp, between the first and second jaws 12, 22, two or more components 51 , 61.
  • the components 51, 61 consist of two stiffening profiles for mutually adjacent formwork panels 50, 60.
  • the first body 10 comprises an elongated element 11 which substantially extends along a first axis 100.
  • the elongated element 11 has a substantially tubular structure and is constituted by a portion 14, which has a substantially U- shaped or C-shaped transverse cross-section which is closed on the open side by a plate-like element 15.
  • the portion 14 and the plate-like element 15 are made so that they can be mutually coupled during production, for example by means of appropriate protrusions and corresponding contoured regions.
  • the plate-like element 15 protrudes laterally with respect to the portion 14, forming a pair of parallel guides 13a, 13b which extend substantially along two entire sides of the elongated element 11 , parallel to the first axis 100.
  • Substantially mutually parallel first contoured wings 16a, 16b protrude at right angles from a first end of the elongated element 11 and form the first jaw 12.
  • first contoured wings 16a, 16b are provided with first grip portions 17a, 17b respectively, which are arranged transversely to the first axis 100 and are adapted to engage the components 51 , 61.
  • the first grip portions 17a, 17b are provided with first teeth 18a, 18b adapted to engage slots 52, 62 defined on the components 51 , 61.
  • a series of contoured protrusions 19 is formed on the outer face of the plate-like element 15 and said protrusions can interact with the locking means 30, as better specified hereinafter.
  • the contoured protrusions 19 are substantially tooth-shaped and extend transversely to the first axis 100.
  • contoured protrusions might be shaped differently in alternative embodiments of the present invention which are not shown.
  • the second body 20 comprises a substantially hollow base portion 21 , which preferably has a U-shaped or C-shaped transverse cross-section.
  • the base portion 21 can be coupled to the first body 10 so that the internal surface of said base portion 21 is in contact with the external surface of the elongated element 11.
  • the second body 20 comprises blocks, in the specific case four blocks 23a, 23b, 23c, 23d, which protrude inside the base portion 21, constituting a sort of channels in which the parallel guides 13a, 13b are inserted slidingly.
  • Second substantially mutually parallel contoured wings 24a, 24b protrude at right angles from the base portion 21 and form the second jaw 22.
  • the second contoured wings 24a, 24b are provided with second grip portions 25a, 25b respectively, adapted to engage the components 51 , 61.
  • the second grip portions 25a, 25b are arranged transversely to the first axis 100.
  • the second grip portions 25a, 25b are provided with second teeth 26a, 26b adapted to engage the slots 52, 62 defined on the components 51, 61.
  • Seats 27a, 27b are furthermore formed on the base portion 21.
  • the seats 27a, 27b, one on each second contoured wing 24a, 24b, are meant to interact with the locking means 30, as better specified hereinafter.
  • the locking means 30 comprise a third body 31 which substantially extends along a second axis 200.
  • the third body 31 is substantially complementary, in terms of shape and dimensions, with respect to the two seats 27a, 27b.
  • the third body 31 is in fact designed to enter the two seats 27a, 27b, so that the second axis 200 is substantially perpendicular to the first axis 100.
  • the third body 31 has, along almost its entire length, slots 32 adapted to engage slidingly the contoured protrusions 19.
  • the slots 32 are designed to cause mutual approach/spacing between the first and second jaws 12, 22 during the sliding of the third body 31 in the seats 27a, 27b.
  • the slots 32 are inclined with respect to the second axis 200 and this allows to convert the sliding motion of the third body 31 with respect to the second body 20, parallel to the second axis 200, into the translation of the second body 20 with respect to the elongated element 11 , parallel to the first axis 100.
  • a head 33 is furthermore formed at one end of the third body 31 and facilitates its hammering by forcing into the seats 27a, 27b.
  • the clamp 1 is assembled by coupling slidingly the second body 20 to the first body 10.
  • coupling occurs by inserting and sliding the parallel guides 13a, 13b of the first body 10 in the channels formed on the second body 20 by the four blocks 23a, 23b, 23c, 23d.
  • the clamp 1 is already ready to be fixed to the components 51, 61 or to the stiffening profiles of two adjacent formwork panels 50, 60.
  • the operator brings the first and second jaws 12, 22 into contact with the components 51, 61, taking care that the first grip portions 17 a, 17b and the second grip portions 25 a, 25b abut correctly against them and that the first teeth 18a, 18b and the second teeth 26a, 26b are inserted in the slots 52, 62.
  • the invention achieves the intended aim and objects, having provided a clamp for formwork for vertical castings that ensures effective locking and perfect positioning of the formwork panels.
