Definitions

  • the present invention relates to the field of the construction industry and public works, in particular the field of the manufacture of construction site materials and in particular the panels for the production of walls or sails, and has for object a removable and self-locking step .
  • the formwork panels for wall and wall formwork are generally equipped, in their upper part, with traffic platforms, access to which is made possible by means of ladders connected to the lower part of the platforms and extending parallel to the boards in the operating position, these ladders being locked in the service position by means of a step pivotally connected to the structure of the formwork and cooperating with the lower part of the ladder by means of hooks or like.
  • steps for maintaining the service position of the ladders, by blocking in position of their lower end are generally in the form of an elongate shelf which is connected at one end to bearings of the infrastructure of the formwork through a removable pin provided with holding pins or the like, the opposite end of said shelf engaging directly or by means of hooks on the lower rung of the ladder.
  • Such a known step is foldable, in the non-use position, against the infrastructure of the form and can be maintained by means of a locking latch or the like.
  • the step and its fixing pin can then be stored separately or reused in connection with a different form.
  • FR-A-2,718,777 discloses a ladder holding brace, which is simply attached to a formwork or formwork through means as defined above.
  • the present invention aims to overcome these disadvantages and proposes to achieve a formwork equipped with a removable and self-locking step allowing a quick and easy fixing and locking on the lower part of the infrastructure of the form, without requiring a means of perdable fixation.
  • the board which is equipped with a step, mounted at one end pivotably near the lower edge of the infrastructure of the formwork and can be connected by its other end to the lower level of a ladder of access to a traffic platform, is characterized in that the fixing of said first end on the infrastructure of the formwork, near its lower edge, is performed by means of a detachable articulation means and plug-in in a single predetermined position, cooperating with a holding and pivot bearing in the service position and automatic locking in non-use position of the step.
  • the fixing of the first end of the step 1 on the infrastructure 2 of the formwork, near its lower edge, is performed by means of a means 4 of removable and plug-in articulation in a single predetermined position (Figure 1), cooperating with a bearing 5 for holding and pivoting in the operating position ( Figure 2) and automatic locking in non-use position of the step (Figure 3).
  • the hinge means 4 is in the form of a fixed axis consisting of two pins, of rectangular or square flat section, extending parallel to the first end of the step 1 and each secured with a corresponding longitudinal edge of said step 1, these pins having an inclination of their central axis relative to the horizontal plane of the step 1, down towards the other end.
  • the bearing 5 for holding and pivoting in the operating position and automatically locking in the non-use position of the step 1 (FIGS. 1 to 3) is in the form of an open bearing of circular inner section, secured to crosspieces 7 of the infrastructure 2 of the formwork and constituted by two parallel cheeks 8 spaced a distance slightly greater than the width of the step 1, the opening 9 of the bearing 5 being of slightly greater width than the smallest dimension of the pins forming the means articulation 4 and the diameter of its inner section corresponding to the diagonal of said pins.
  • the hinge means 4 of the step 1 for securing said step 1 with infrastructure 2 of the form, is captive. Indeed, only involved the open bearing forming the bearing 5 and holding pivoting fixed axis equipping the first end of the step 1.
  • these pins advantageously have at least rounded edges.
  • the particular shape of the open bearing and that of the fixed axis have the effect that the fixed axis can be introduced into the open bearing only in its smallest dimension, that is to say only when the step 1 has an orientation with respect to the opening 9 of the bearing 5, the smaller dimension of the fixed axis is oriented perpendicular to the axis of this opening 9 and that its median axis of greater dimension is parallel to this axis of the opening 9.
  • Figure 1 of the accompanying drawings Such a position is shown in Figure 1 of the accompanying drawings.
  • the step 1 in the operating position, the step 1 is fixed at its other end to the lower level 11 of a ladder 3 access to a traffic platform by means of attachment tabs 10 relying on said rung and at least one automatic lock 12 snapping under the rung 11.
  • a lock 12 is of a type known per se and comprises a mounting box under the front edge of the step 1 and housing the latch itself and its return spring, the rear end of the latch being provided with an operating eyelet.
  • the open bearing forming the bearing 5 for holding and pivoting in the service position and automatic locking in the non-use position of the step 1 is provided, in addition, in each cheek 8 the forming a groove 10 of the same section as its opening 9, this groove 10 having an inclination relative to the vertical equal to the inclination of the pins forming the hinge means 4 of the step 1 relative to the longitudinal axis of said step 1.
  • the pins forming the hinge means 4 of the step 1 have their median axis of greater dimension perpendicular to the axis of the opening 9, so that they are supported by their two opposite sides of smaller width, or at least by their edges, in the bearing 5.
  • the pins forming the hinge means 4 of the step 1 penetrate the bottom of the grooves 10 of the cheeks 8 and thus block the step 1 in its position parallel to the infrastructure 2 of the form.
  • This positioning and blocking are simply performed by pivoting the step 1 upwards, so that the pins extend with their smallest dimension perpendicular to the edge of the grooves 10 and they can thus slide in the latter.
  • the arrival at the end of the penetration run in the grooves corresponds to the automatic locking position for packing or transport, in which the pins can in no case turn, so that the step 1 is maintained and can not be released the position only subject to voluntary displacement, which can not occur in a packing or transport position.
  • Unlocking is carried out by simply moving it in the opposite direction until the pivoting position is reached (figure 2).
  • a removable and self-locking step particularly for formwork board and intended in particular to simultaneously achieve access to a ladder access to a safety platform and locking in the service position of this scale.
  • Such a step has the advantage of being quick and easy assembly and not implement any additional means may be lost during a possible disassembly or during unfolding or folding operation.
  • such a step is automatically locked in its pivot bearing in the service position and is also automatically locked in the folded position against the infrastructure of the form.
