Definitions

  • the present invention relates to a prefabricated floor provided with safety fastening devices to allow fixing on horizontal crosspieces of scaffolding or a similar construction with excellent fixing stability.
  • a metal floor has the advantage over a traditional wooden floor of being lighter and less degrading.
  • a metal floor is usually made of a folded metal sheet and / or stamped to form a resistant box.
  • Each metal floor is provided with fasteners for suspension and fixing on horizontal sleepers of a construction, for example a scaffolding or a framework.
  • the fasteners are usually legs intended to be placed on a horizontal crosspiece in order to thus suspend the floor.
  • This method of attachment is not opposed to lifting (for example by the wind) or play which are detrimental to the stability of the floor and the safety of site personnel, people and property. This method of attachment therefore does not ensure locking on the cross-member. An imbalance of the load on the floor can therefore produce a movement of the floor and constitute a danger for site personnel.
  • the invention aims to remedy the drawbacks of the known technique. Its purpose is to provide a prefabricated floor having fastening devices which not only ensure easy locking and unlocking, but also locking. reliable and automatic, capable of guaranteeing perfect seat stability on the floor.
  • a floor consisting of a profile, each end of the profile being closed by a support comprising a vertical member on which are fixed two suspension hooks intended to fit a horizontal crosspiece of a construction, said vertical member being pierced with at least one opening having its horizontal axis situated in the same vertical plane as the longitudinal axis of a suspension hook.
  • the aforementioned opening allows the passage of the upper part of a lock attached to the lower part of the support so as to be able to pivot in a vertical plane and so that, when the corresponding suspension hook is placed on a horizontal cross-member, the lock cooperates with the lower lateral surface of the cross member and presses against it.
  • the upper part of the lock is profiled so as to always ensure the best contact between the lock and the crosspiece, regardless of the relative position of these two parts.
  • an exemplary floor consisting of a metal profile 1 having a general U shape.
  • the profile 1 is for example made of galvanized steel.
  • the main face 11 of the profile has parallel bosses 12 serving as load distributors.
  • non-slip reliefs 14 in any number.
  • suspension hooks 2 intended to fit two horizontal crosspieces of a construction, for example a scaffolding, so as to suspend the floor 1.
  • stiffeners are usefully provided inside the profile in order to ensure the desired stiffness combined with the desired lightness of the assembly. They each consist of a section welded between the ends of the lower wings of section 1.
  • Figure 4 shows on an enlarged scale one end of the floor 1 and it shows in particular a hooking and locking device for fixing the floor on a horizontal crosspiece of a construction.
  • the hooks 2 are welded to a support 3, consisting for example of a U-shaped iron, fixed at the end and inside the profile 1.
  • the core of the iron 3, that is to say -to say the vertical member of the support is pierced with an opening 4 having its horizontal axis located in the same vertical plane as the longitudinal axis of one of the suspension hooks 2.
  • In the opening 4 passes the upper part of a pivoting lock 6 hooked to the lower part of the support 3 so as to be able to pivot in a vertical plane.
  • the lower end of the bolt 6 passes through an opening in the lower wing of the iron 3 and it is provided with a hooking head 7 constituted, for example, by a self-tapping screw with a cylindrical head.
  • the attachment head 7 ensures the suspension of the lock 6 while allowing the pivoting thereof around a horizontal axis.
  • a lock 6 is provided at each end of the floor 1 as shown in Figure 1. It is obvious that one could provide two locks at each end, although in practice a lock at each end is sufficient to ensure the security of the fixation.
  • Unlocking a binding is also very simple.
  • a pressure on the heel 62 of the latch 6 is sufficient to rotate the latter in the opposite direction to that of the movement of the needles of a watch and release it from the cross-member.
  • the exemplary embodiment of the locking device according to the invention also has the advantage of allowing easy replacement of the lock 6.
  • the latter is attached to the support 3 by a head formed by a screw 7, just unscrew the head 7 to remove the lock 6 and screw the head 7 into the new lock.
  • the profile 1 and the latches 6 are produced in such a way that the lateral wings 15 and 16 of the profile (see fi gure 3) protect the latches 6 when they are in their raised position (unlocking position).
  • the heel 62 of the latch 6 does not exceed the lower wing 17 of the profile when the latch is raised.
  • the fact that the bolts 6 of a floor are thus retractable inside the profile 1 makes it possible to lay the floors on the ground, without risk of damaging them, and this facilitates the storage of the floors according to the invention.
  • the main face 11 of the profile 1 has parallel bosses 12 ( Figures 1 and 2). These bosses 12 delimit between them channels 13 which facilitate the flow of rainwater, in particular through holes 18 located in the channels 13. In this way, rainwater does not stagnate on the surface of the floor and This prevents ice sheets from forming in freezing weather, which increases safety for site personnel.
