Definitions

  • the present invention relates to a scaffolding connecting device for connecting the ends of a horizontal scaffolding element to a vertical scaffolding element.
  • a connecting device of this kind is known from the publication of European patent application 0110027.
  • This known device comprises two spaced annular supports fixed to a vertical scaffolding element and a hooking piece fixed to one end of a connecting element. 'horizontal scaffolding.
  • the attachment piece has two recesses intended to fit on two annular support shoulders fixed on a vertical element.
  • the horizontal element and the vertical element are assembled by simply pressing the attachment piece on the support shoulders, the retention of the attachment piece on said shoulders being ensured by a locking key mounted to slide under the attachment piece.
  • This linkage device ensures an alignment with respect to a reference axis which passes through the two shoulders, which makes the tribular assembly of the manufacturing tolerances.
  • the connecting devices according to the prior art produce rigid mounting nodes which have no elasticity to respond to load stresses.
  • the invention aims to overcome the drawbacks of the prior art thanks to an improvement to a connecting device for connecting a horizontal bar to a vertical column, which comprises a hooking piece fixed to one end of the horizontal bar for couple with at least one annular support element fixed on the vertical column, and a locking device.
  • the support element has a collar having an inclined peripheral rim which forms an annular bowl, the radial width of which decreases progressively from its upper edge to the bottom of the bowl, and the attachment part has at least one extending spout down and shaped to engage tightly inside the bowl of a flange so that when it is inserted into said bowl, the spout is wedged elastically between the vertical column and the peripheral annular rim of the bowl.
  • the device locking includes a cam pivotally mounted on the attachment piece so that when the spout is in contact with the upper part of the peripheral flange of the flange, the cam is against the flange and so that, under the pressure exerted by the action of the cam, the spout engages towards the bottom of the bowl so that the cam applies a prestressing force on the flange which elastically locks the spout in the bowl of the support flange.
  • FIG. 1 is an exploded view of an exemplary embodiment of the connection device according to the invention, .
  • FIGS. 2 to 4 illustrate the successive stages of the process of coupling the parts constituting the connection device mounted in FIG. 1.
  • the connecting device shown in Figure 1 is used to connect a horizontal bar 2 to a vertical column 1 to form a connecting node in a scaffold.
  • the connection device comprises two support flanges 10 fixed to the column 1 using dowels 3 and a hooking piece 20 fixed to one end of the bar 2 using dowels 4 and 5.
  • the other end of the bar 2 is equipped with a similar attachment piece intended to be coupled to a support device provided on another vertical column.
  • the support device could also comprise only a single flange 10.
  • the or each support flange 10 is constituted by a ring 11 formed with an inclined peripheral rim 12 so as to delimit a flared annular bowl 13.
  • the two support flanges 10 could perfectly be produced in the form of a single support piece.
  • the attachment piece 20 consists of a metal profile having two spouts 21 intended to engage in the bowls 13 of the support flanges 10.
  • the spouts 21 are shaped to fit in the bowls 13 with progressive tightening, the spouts having an inclined flank 22 to adapt against the peripheral rim 12 of the flanges 10 and a flank 23 to adapt against the rings 11.
  • Inside the profile is housed a locking piece 24 mounted on a pivot 5 passing through the hole 26 and coming to be housed in the holes 27 of the wings of the profile constituting the attachment piece.
  • the locking piece has a cam profile 25 and a spring arm 28 which will be seen below.
  • FIGS. 2 to 4 When inserting a spout 21 in a bowl 13, the progressive tightening between the sides 22 and 23 of the spout and the walls 11 and 12 of the bowl produces an elastic wedging of the spout 21 in the bowl 13.
  • This elastic tightening progressive is illustrated by FIGS. 2 to 4.
  • the nozzles 21 of the attachment piece 20 are ready to be introduced into the cups 13 of the support flanges 10.
  • the locking device 24 is advantageously retained thanks to a lug 29.
  • the profile of the spouts 21 ensures good progressive tightening.
  • the lower spout 21 of the attachment piece is accommodated flexibly and elastically in the lower bowl 13. If we have released the pin of retainer 29 of the locking piece 24, the latter is pivoted about its axis 5 to bring the cam profile 25 against the circular edge 15 of the upper flange 10.
  • the cam profile 25 is drawn in such a way that, when the locking piece 24 is pivoted in the direction of the arrow V, the cam profile 25 slides on the edge 15 and the flange by pulling the spout 21 towards the bottom of the bowl while applying a progressive prestressing force on the collar 10.
  • the hooking spouts 21 descend to the bottom of the cups of the support flanges 10, these undergo a slight elastic deformation due to their annular shape and this elastic deformation promotes engagement while ensuring elastic tightening.
  • This elastic deformation effect is indicated in FIGS. 2 to 4 by the marks D1, D2 and D3 which designate the successive diameters of the opening of the upper bowl during the insertion process (D1 ⁇ D2 ⁇ D3).
