Definitions

  • the present invention relates to a method of connecting a prefabricated floor with a horizontal cross member of a construction, the floor consisting of a profile, each end of which carries a support comprising a vertical member on which are fixed two suspension hooks intended for place and fit the horizontal crosspiece of a construction, said vertical member being pierced with at least one opening having its horizontal axis located in the same vertical plane as the longitudinal axis of one of the suspension hooks, the aforementioned opening allowing 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 the horizontal cross-member, the lock cooperates with the lateral surface of the crosspiece.
  • the invention also relates to a prefabricated floor for implementing the method.
  • 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 the site personnel.
  • FR-A-2485598 is known a platform for metallic tubular scaffolding which comprises at its ends at least one ring of triangular shape which is threaded through a hole made in a wing of U-shaped profiles with which the ends are fitted. of the platform.
  • the aforementioned ring certainly constitutes a retaining means for the platform but the maintenance of the platform on a horizontal cross-member is done with a clearance so that the ring does not bear against the surface of the cross-member and does not ensure a clamping of the platform on the crosspiece.
  • the ring in question does not automatically carry out the locking during the same hooking operation and the fixing of a platform on a cross member therefore requires two successive operations: a hooking operation and a locking operation .
  • the invention aims to remedy the drawbacks of the known technique. It offers a prefabricated floor with fastening devices which not only ensure easy locking and unlocking, but also reliable and automatic locking, capable of guaranteeing perfect seating stability on the floor.
  • a method of connecting a prefabricated floor with a horizontal cross member of a construction said floor consisting of a profile, each end of which carries a support comprising a vertical member to which two suspension hooks intended to be placed and to fit the horizontal crosspiece of a construction, said vertical member being pierced by at least one opening having its horizontal axis situated in the same vertical plane as the longitudinal axis of one of the suspension hooks , the aforementioned opening allowing 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 suspension hook corresponding is placed on the horizontal cross member, the lock cooperates with the lateral surface of the cross member, said method being characterized in that the lock is hooked by its lower end to a horizontal wing of the support so that it can pivot in a vertical plane and lean against the lower lateral surface of the horizontal crosspiece.
  • the lower end of the bolt crosses the horizontal wing of the support in an opening.
  • the lower end of the lock is hooked to the support using a head consisting of a screw.
  • a prefabricated floor consisting of a profile, each end of which carries a support comprising a vertical member on which two suspension hooks are fixed. intended to fit a horizontal cross member 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 allowing 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 surface lower lateral side of the cross member, said floor being characterized in that the latch is hooked by its lower end e to a horizontal wing of the support so as to be able to pivot in a vertical plane and to bear against the lower lateral surface of the horizontal cross-member.
  • the lock always ensures the best contact with the crosspiece, whatever the relative position of these two parts, and achieves, in a single operation, both the attachment and the locking of a floor on a horizontal crosspiece.
  • This method thus prevents any tilting of the floor under the weight of a person walking on the floor and also prevents any possibility of lifting of the floor by the wind, which ensures excellent fixing stability of the crosspiece.
  • the latches are fully retractable inside the profile, and this allows easy and compact storage of prefabricated floors provided with their suspension hooks.
  • Figure 1 is an elevational view of an exemplary embodiment of a floor according to the invention.
  • Figure 2 is a plan view of the floor of Figure 1.
  • FIG. 3 is a cross section along line III-III of FIG. 2.
  • Figure 4 is a sectional view, on an enlarged scale, of the attachment and locking device according to the invention.
  • Figure 5 is a view similar to that of Figure 4 but showing the locking device in the unlocked position.
  • 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 attached 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 5 formed 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 latch 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 to 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. In fact, since the latter is attached to the support 3 by a head formed by a screw 7, simply 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 figure 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 define 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.
