Definitions

  • the present invention relates to a floor element for scaffolding.
  • the invention relates to an element having the general shape of a plate which can be placed and fixed on horizontal elements of a scaffolding assembly in order to allow the movement of workers working on a site where is mounted this scaffolding.
  • FIG. 1 There is shown schematically in Figure 1 attached a part of a scaffolding consisting of vertical elements such as 10 and horizontal elements 12 connecting together the vertical elements 10. There is also shown a part of a floor 14 which is constituted by sets of metal plates or profiles 16 which are arranged side by side in line with each other. Each floor element 16 has at its ends means 18 for fixing the plates 16 to the horizontal scaffolding elements 12.
  • the fastening systems must, on the one hand, avoid the lifting of the floor elements, for example under the effect of a strong wind, and on the other hand, they must avoid the spillage of the floor element, c 'is to say the tilting of the floor element and whatever the place of this element where the worker is supported. It is also desirable that the fastening system has active safety characteristics, that is to say that the disassembly of the floor element relative to the scaffolding elements can only be obtained by a voluntary action of that who does this disassembly.
  • the floor element for scaffolding comprising an elongated plate provided at each of its ends with means of fastening on horizontal scaffolding elements extending perpendicular to the length of said floor element, is characterized in that each securing means comprises at least two sets forming hooks, projecting out of the corresponding end of said plate and able to rest on a horizontal scaffolding element, said two hooks being spaced along the width of said plate, each hook assembly having an extension resting on one end of the plate of an adjacent floor element in the direction of the length of the floor element, the hook assembly of a first end of the plate being offset along the width of the plate relative to the hook assemblies of the second end d 'a distance d at least equal to the width of a hook element.
  • each securing means further comprises a retractable locking assembly comprising at least one lock pivotally mounted relative to the end of said plate and one end of which protrudes from the end of said plate in view of the hook elements, said latch being held in its locking position by counterweight means, the end of said latch being able to be moved away from its locking position by the scaffolding element during the positioning of said floor on said scaffolding element.
  • each end of a plate is locked on the horizontal scaffolding elements by the cooperation of a hook and a latch which is held in its locking position by the effect of the counterweight, which avoids any risk of spillage under the effect of a load applied to the plate.
  • the lock is pivotally mounted on a part forming a lever, a first end of which is articulated relative to said end of the plate and the other end of which is secured to the means forming a counterweight.
  • each retractable locking assembly comprises two identical locking elements mounted at each end of the width of the end of a plate, each locking element comprising a latch, one end of which is articulated on a part forming a lever, said part forming a lever having a first end secured to an axis of rotation common to the two locking elements and a second end secured to a rod common to the two locking elements forming a counterweight and a control handle.
  • FIG. 2 we will describe the assembly of a floor element according to the invention.
  • This consists on the one hand of an elongated plate 32 or more precisely preferably by a profile comprising an upper plate 34 and two lateral edges, only the edge 36 being visible.
  • the dimensions of the rim 36 and the choice of the thickness of the profile naturally depend on the total dimensions of the floor element as well as the loads to be supported.
  • the plate 32 is provided with fastening means respectively referenced 38 and 40.
  • Each fastening means 38 or 40 comprises on the one hand hooks, bearing the general reference 42, which are intended to come to bear on horizontal scaffolding elements such as 44 and a locking assembly bearing the general reference 46 which, after the installation of the floor element on the scaffolding element 44, ensures the joining of the floor element on the scaffolding.
  • the hook 42 and the locking system 46 are mounted on a U-shaped part 48 which is welded to the ends of the plate 32 in the direction of the width of the latter.
  • the hooks, such as 42 comprise a fixing part 50 welded to the U-shaped part 48 a spout 52 ensuring the hook function and a horizontal extension 54 which extends beyond the spout 52.
  • the lower face 54a of the extension is arranged substantially in the same horizontal plane as the upper face of the plate 34.
  • FIG. 3 there is shown the plate 32a of a first floor element 30a and part of the plates 32b and 32c of floor elements 30b and 30c aligned with Element 30a.
  • the first end of the plate 32a is provided with hooks 42 1 and 42 2 while its second end is provided with hooks 42 3 and 42 4 .
  • the hooks of one end 42 1 and 42 2 are offset relative to the hooks 42 3 and 42 4 of the other end. This offset is equal to d and is slightly greater than the width of a hook element. This offset d allows the hooks to come to bear directly on the scaffolding elements 44, 44 '.
  • FIG. 4 illustrates the positioning of the floor elements 32a and 32b on a scaffolding element 44. Due to the mutual overlap of the floor elements, due to the presence of the extensions 54, the positioning of these elements floor is made by lifting the ends thereof and lowering them simultaneously, which allows the final positioning of the two floor elements on the scaffolding element 44, the different extensions 54 thus being nested.
  • the locking element 46 is essentially constituted by two parts 70 and 72 which are preferably identical and articulated with respect to each other.
  • the part 70 which will later be called a lever, is fixed at a first end 74 to a rod 76 whose axis is orthogonal to the plane of the part 70.
  • the part 70 is integral with a rod 80 parallel to the rod 76 and which constitutes a counterweight.
  • the rod 76 which forms a pivot axis is engaged at its ends in two housings such as 82 integral with the U-shaped part 48.
  • the part 70 is provided with an orifice 84 in which is engaged a lug d hinge 86. This lug is also engaged in an orifice 87 formed near the first end 88 of the part 72.
  • the second end of the part 72 which is referenced 90 is provided with an orifice 92 in which one can engage removable lug 94.
  • each end of the plate is provided with two identical locking systems, one being referenced 46 and the other 46 '. These two locking systems are interconnected by the rods 76 and 80.
  • the U-shaped pieces 48 have two slots, such as 100, to allow the passage of the pieces 72 so that their ends 90 protrude out of the plate elements.
  • the ends 90 of the parts 72 forming a lock are arranged opposite the element 42 forming a hook.
  • the bar 80 forming a counterweight also constitutes the equivalent of a handle which can be grasped by the worker responsible for removing the floor elements, as will be explained later.
  • FIG. 6 shows locking devices 46 of two adjacent floor elements before their engagement on a horizontal scaffolding element 44. It can be seen that, in this position, the ends 90 of the parts 72 protrude completely from the ends of the elements of floor.
  • the scaffolding element 44 causes the withdrawal of the ends 90 of the locking pieces 72 by pivoting the piece 70 around of its axis 76 and pivoting of the part 72 relative to the part 70 around the axes 86.
  • the two floor elements can be lowered until the scaffolding element 44 is engaged in the elements forming a hook 42. After this engagement, the ends 90 of the parts forming a lock 72 return to their initial position under the effect of the counterweights 80. This is what is shown in FIG. 8 for position 1 of the locking elements.
  • the withdrawal of the ends 90 of the locks 72 is limited by the presence of the lugs 94 which cooperate with the edges of the slots 100 formed in the U-shaped pieces 46.
  • the lugs 94 are removable because the initial installation of the locking system 46 is done without the lugs, these being set up only later.
  • the locking system 46 is put in place after all of the rest of the floor element has been completed. For mounting the locking system, the lugs 94 are not in place.
  • the locking system is presented inclined with respect to the plate 34.
  • One end of the rod 76 is engaged in one of the housings 82 and fully depressed up to the free clearance limited by the contact between the part 70 and the corresponding housing 82, then the rod 76 is straightened and inserted into the second housing 82.
  • the rod 76 is positioned so that the ends 90 of the latches 72 protrude out of the slots 100 formed in the U-shaped part 48.
  • the pins 94 are then put in place in the orifices 92 and secured to the parts 72.
  • the floor element is then completely assembled.
  • the scaffolding element according to the invention makes it possible to solve effectively and at a reduced cost the problems of lifting and spillage.
  • the installation and removal of the floor elements on or off the scaffolding are very simple to implement. Indeed, the establishment is carried out without any particular operation while the removal is carried out conveniently thanks to the presence of the handles which are easily accessible from below the floor elements.
