Definitions

  • the present invention relates to a device for protecting people working on construction sites or prefabrication workshops, against the risk of accidents due to protruding rods, in particular steels on standby in reinforced concrete construction elements, in the field of public works and building.
  • an ankle protection device which is constituted by a cabochon-shaped element, made of flexible plastic material, which fits on the end of the ankle.
  • a cabochon-shaped element made of flexible plastic material, which fits on the end of the ankle.
  • grooves In the central cavity of this element, are practiced grooves, which should, in principle, facilitate the fitting of the protective element on the ankle.
  • this element which seems very provisionally retained when it is in place, does not constitute a safe and acceptable protection to protect people against the risk of accidents due to the steels waiting in the reinforced concrete parts.
  • the present invention aims to remedy the drawbacks which have just been exposed, by proposing, in one of its aspects, an element of individual protection of the projecting rods on construction sites and prefabrication workshops, of easy installation and ensuring a totally reliable protection, the protection element not risking, in the event of an impact, being punctured or ejected.
  • the invention offers the additional advantages of proposing a protective element which can adapt to projecting bars or rods of different diameters, of being able to be reused a large number of times, and also of being able to be manufactured in a simple manner and at low cost. .
  • the present invention therefore firstly relates to a protective cap intended to come to cover the end of a projecting rod, such as a metal bar waiting in the reinforced concrete construction elements, this cap comprising a connected skirt to a bottom and being provided internally with means for retaining the cap on the end of the projecting rod, characterized in that the skirt is connected to the bottom by a part defining internally a substantially frustoconical wall opening in the direction of the free end of the skirt and constituting an abutment region for the protruding rod and damping in the event of impact, said skirt extending, opposite said bottom, by a part comprising a zone for retaining by pinching the rod .
  • French patent application No. 2 459 763 describes a protective cap comprising gripping means making it possible to hold it on the end of a rod prominent.
  • the frustoconical part connected to the head of the protective cap according to the invention is oriented inversely with respect to this known cap.
  • This frustoconical part of the known cap does not in itself provide damping, the proof being that we must bring back an additional part, namely a foam rubber stopper, to obtain this damping effect.
  • the pinching means there is provided, in this cap known by French patent application n ° 2 459 763, a single median pinching, which has the consequence that the protective tip risks, in real conditions of use, pivot around an axis perpendicular to the pinch area.
  • the pinching takes place at two points, namely at the level of the upper frustoconical part, by circular support forming a stop, and, in the lower part, by the pinching zone.
  • German patent application No. 2 834 489 is a protective cap having a frustoconical skirt widening downwards, this cap being intended to be applied to the threaded end of metal or other tubes.
  • the skirt is frustoconical, but it is provided with ribs against which the threading of the rod will be positioned, the contact being made on the upper parts, which, in turn, define a zone of cylindrical envelope, the parts lower ribs being flared only to form an inlet cone.
  • German patent application No. 2 106 996 is a protective cap which has an ogival part.
  • This ogive part is intended for the case where it is desired to apply the cap on materials with a tapered end.
  • the warped profile would in any case absolutely not damping in the event of an impact, as does the frustoconical part of the cap according to the invention. This is applicable to protection against rods with any end.
  • the part comprising the pinching zone is constituted by a frustoconical zone which is connected to the part of the skirt defining the damping cone, which narrows in direction of the free end of said skirt and then opens at this end to constitute an inlet cone, at least one substantially longitudinal slot being formed at least in the constricted region of the part of the skirt comprising the pinching zone.
  • the part of the skirt comprising the pinching zone comprises several slots regularly distributed at the periphery of said skirt. Furthermore, the slots advantageously open at the free end of the skirt.
  • the bottom of the protective cap is preferably thickened, to help absorb energy in the event of an impact, and, moreover, it can advantageously constitute a gripping head for said cap.
  • the Applicant Company has also imagined adapting the particularly interesting characteristics of this cap to an envelope profile intended to cap an alignment of primers. Indeed, it frequently happens on major sites that the irons pending in the reinforced concrete construction elements are aligned and, in this case, the application of an envelope profile simultaneously covering several irons or protruding rods in alignment requires less time than applying individual caps.
  • the present application also relates to such a cap in the form of an envelope profile which makes it possible, thanks to its characteristics, to retain all the advantages of protection by individual caps.
  • the present invention therefore also relates to a protective cap intended to come to cover the ends of projecting rods in alignment, such as waiting metal bars in the reinforced concrete construction elements, this cap being constituted by a section-envelope comprising wings connected to a bottom and being provided with retaining means on the ends of the projecting rods, characterized in that each wing is connected to the bottom by a part inclined towards the outside, the interior zones substantially V-shaped of these two inclined parts constituting a stop region for the protruding and damping rods in the event of an impact, each inclined part extending, opposite said bottom, by a part comprising a retention zone by pinching the rods by cooperation with the same zone of the opposite wing.
  • the part of a wing comprising the pinching zone is constituted by a band inclined towards the inside, which is connected to the part of the wing defining the damping zone, and which ends by a strip inclined again towards the outside, the intermediate zone between these two bands defining the pinching zone.
  • this protective cap of the invention is preferably thickened to help absorb energy in the event of an impact, and, moreover, it can advantageously constitute a gripping head for said cap.
  • this base may have longitudinal grooves in its longitudinal side walls, which allows a saving of material in molding without harming the desired functions of the cap.
  • the cap 1 is made in one piece by molding, for example by injection, of an impact-resistant thermoplastic, such as high density polyethylene. It is constituted by an elongated side skirt 2, connected to a bottom 3 of great thickness, which constitutes a gripping head of the cap 1 during its installation.
  • an impact-resistant thermoplastic such as high density polyethylene
  • the bottom 3 is delimited by a cylindrical side wall 4, by an upper wall 5, slightly curved, and by a lower wall 6, the skirt 2, which has a longitudinal axis of symmetry coincident with that of the bottom 3, connecting so annular in the vicinity of the periphery of the wall 6.
  • the connection between the external wall of the skirt 2 and the bottom 3 takes place in a rounded zone 6 a , of profile substantially in an arc, of concavity turned towards the outside . It is thus constituted, in this region, an annular reinforcement which is intended to contribute to the holding of the cap 1 in the event of an impact.
  • the skirt 2 has a frustoconical shape, flaring opposite to a bottom 3, in its connection zone 7 with the latter, this zone 7 being extended by a frustoconical zone 8 tapering towards its end, where it s 'opens outwards to form a zone 9, through which the cap 1 is introduced on the end of the metal rod 10 to be protected ( Figure 4).
  • the frustoconical zone 7 is delimited, on the one hand, by an external wall 7 a , connected to the wall 6 by means of the above-mentioned rounded zone 6 a , and, on the other hand, by an internal wall 7 b , which is connected to a conical recess 11 ending in a rounded bottom 12, which is formed in the wall 6.
  • a damping cone 13 which is delimited by the walls 7b and 11 and through the bottom 12, and the function of which is described in more detail below.
  • the tapered zone 8 of the skirt 3 has four longitudinal slots 14, disposed at 90 ° from each other, following which end a rounded bottom 14a in the vicinity of the junction of the zones 7 and 8 the skirt 2, and which extend into the inlet cone 9, to open to the outside. There are thus formed four elongated legs 15, which will move apart when the cap 1 is put in place.
  • the internal diameter of the cap 1, in the connection zone 16 between the zone 8 of the skirt 2 and its cone inlet 9 is less than the minimum diameter of the different rods that the cap 1 is capable of coming to protect, so that this zone 16 constitutes a pinching zone allowing the cap 1 to be maintained.
  • FIG. 4 represents the cover 1 in its active position, in place on a projecting rod 10. In this position, it can be seen that the tabs 15 are slightly apart to ensure the pinching of the rod 10. Also, this figure shows that the part tapered 13 acts as a stop for translating the cap 1 in translation. This makes it possible, in combination with the pinching zone 16, to hold the cap 1 very securely on the rod 10.
  • the installation of the cap 1 on the rod 10 is carried out in a very simple manner, the shape of the head 3, without sharp angles, facilitating the gripping of the cap 1.
  • the shock created causes the cap 1 to sink further onto the rod 10, the corresponding position of the latter being shown in phantom in Figure 4.
  • the energy created by the shock is therefore absorbed by the damping cone 13.
  • the rod 10 therefore does not pass through the cover 1, which then fully plays its protective role.
  • the cap 101 in the form of an envelope profile, is made in one piece by molding, for example by injection, of an impact-resistant plastic, like high density polyethylene. Its length can be varied as a function of the approximate number of irons in alignment which it is desired to be able to cover simultaneously with this cover 101.
  • the cover 101 has a plane of symmetry perpendicular to the average longitudinal line of the bottom 103, and is constituted by two facing wings 102, connected to a bottom 103 of great thickness, which constitutes a gripping head of the cover 101 during its implementation.
  • the bottom 103 is delimited by two opposite longitudinal side walls 104, by a slightly curved upper wall 105, each wing 102 connecting to the associated longitudinal side wall 104 by a rounded wall 106, of profile substantially in an arc of a circle, of concavity. facing outward. It is thus constituted in these regions of the reinforcements intended to contribute to the holding of the cap 101 in the event of impact.
  • grooves 104 a have been made. These grooves 104 a are optional; they simply save material for molding, bringing no discomfort to the functions of protection and gripping head of the bottom 103.
  • the wings 102 have a substantially constant thickness, except in the junction zone with the wall zones 106 where they gradually thicken from the outer surface.
  • Each wing 102 has a connecting portion 107 with the bottom 103, inclined outward, this connecting portion 107 being extended by a strip 108 inclined in an opposite manner, that is to say inwardly, to be end with a strip 109, shorter, again inclined towards the outside.
  • the connecting parts 116 between the strips 108 and 109 are formed by thin strips parallel to the plane of symmetry of the cover 101.
  • the interior surfaces 113 of the parts 107 which form a V-shaped profile and which meet along a line 112 belonging to the bottom 103, form an abutment zone for the ends of irons or primers from which one wishes to protect, as well as shock absorption.
  • the two connecting parts 116 internally form the nipping zone of the succession of pending irons which it is desired to cover with the aid of the cap 101.
  • the placement of the cap 101 on the ends of the waiting irons is carried out in a very simple manner, the shape of the head 103, without sharp angles, facilitating the gripping of the cap 101. This is presented on the end of the irons pending by the input strips 109 which open while deviating slightly.
  • the ends of the primers come, when the cap 101 is put in place, in abutment against the surfaces 113 of the parts 107.
  • the position of these primers relative to the cap 101 is similar to that which is represented in FIG. 4.
  • the shock created means that the cap 101 sinks further onto the ends of primers, the corresponding position of the latter being similar to that shown in phantom in Figure 4.
  • the energy created by the shock is therefore absorbed by the damping zones 113.
  • the ends of the primers therefore do not pass through the cap 101, which then fully plays its protective role.
