Definitions

  • This invention relates to a modular parapet used to provide temporary protection against accidental falls from structures, especially raised structures on building constructions.
  • protective guards in the form of temporary parapets round the structural parts to construct a protective barrier against falling.
  • the parapets are attached to suitable anchoring means provided for the purpose on the structure itself.
  • these anchoring means may be embodied by fixed tubes which, in the case of building roofs, are normally distributed at regular intervals along the edge round the roof, are supported in cantilever fashion by the roof and are rigidly attached to the roof by robust brackets.
  • the prior art knows several protection systems based on prefabricated, modular metal components, for example, comprising tubes of various lengths and ready-made couplers which can be assembled and attached to the structure to form temporary parapets while work is in progress and which can be removed when work has been completed.
  • a disadvantage of prior art is that it requires keeping a relatively wide range of components, such as tubes of different lengths, from which the ones most suitable for erecting parapets to meet specific working requirements can be selected when necessary.
  • This invention therefore proposes a modular parapet used to provide temporary protection against accidental falls from structures equipped with fixed, long anchoring elements, the parapet being characterized in that it comprises a protective barrier, at least one supporting upright that can be associated with a corresponding anchoring element, and means for attaching the barrier to the upright in such a way that it can be engaged and disengaged.
  • the invention also provides an advantageous method for erecting the parapet.
  • the numeral 1 denotes in its entirety a modular parapet used to provide temporary protection against accidental falls from structures 2, especially raised structures on building constructions, such as the roofs of buildings for example. Protection of this kind is advantageously used in particular during the construction or repair of the structure 2.
  • Figure 1 shows that the building structures 2 - which this specification refers by way of example and without limiting the scope of the invention - are customarily equipped with fixed, long elements 5, which are cantilever-mounted on, or project from, the structures 2 themselves and which are attached to the latter by means of robust brackets 20.
  • the long elements 5 are distributed at regular intervals along the edge running all round the structures 2 to provide suitable means for anchoring the parapets 1 or equivalent accident prevention means.
  • the parapet 1 essentially comprises a barrier, or barrier body 3, in the form of a framework, and uprights 4 designed to connect the barrier 3 to the long anchoring elements 5 mounted on the structure 2.
  • the barrier 3 and the uprights 4 can be easily assembled and dismantled so that the parapet 1 can be quickly erected when work is in progress and just as quickly removed when no longer required.
  • the barrier 3 preferably of a plastic material, is in the form of a framework made as a single part extending principally in two dimensions and essentially comprising, for example, three horizontal rails 7 and four vertical stiles 19, all stably interconnected with one another.
  • the tubular uprights 4 are box shaped, open at their opposite ends, and can be associated individually to a corresponding anchoring element 5, in such a way that they are axial with each other, by slidably coupling the inside surfaces of each upright 4 to the outside surface of the anchoring element 5.
  • the uprights 4 are also fitted with outside connecting means 6 or 8 and 9, integral with the uprights 4 themselves and designed to rigidly, but adjustably relative to one another, join the barrier 3 to each of the uprights 4 by clamping on the rails 7 at any point along their length depending only on the specific requirements of the site where the parapet 1 is being erected.
  • the connecting means 6 or 8 and 9 essentially comprise a pair of retaining members 8 and 9 located substantially at the ends of the upright 4.
  • a first retaining member 8 is formed as a single part with the tubular upright 4, to which it is rigidly connected for example by welding.
  • a second retaining member 9 is pivotally mounted on the upright 4 which, for this purpose, is equipped with a support 21 for mounting a hinge pin 22.
  • the second member 9 swings between two end positions, at a first of which the retaining member 9 is inoperative and away from the respective rail 7 of the barrier 3. At the second end position, on the other hand, the retaining member 9 is associated with the edge of the rail 7, in a working condition, as will become clearer as this description continues.
  • the retaining members 8 and 9 have concave profiles 8a and 9a, opposite one another.
  • the profiles 8a and 9a are also shaped to closely match at least parts of the edge of the rails 7.
  • the retaining members 8 and 9 are therefore able to encompass the edge of the respective rails 7 and to fit snugly round one rail 7 or the other in a pair forming part of the frame, in particular, the top rail 7 and the bottom rail 7 of the barrier 3, illustrated in Figure 2 .
  • the profiles 8a and 9a and the edge parts of the longitudinal rails 7 have the shape of matching wedges.
  • the parapet 1 also comprises means 12 and 4 for locking the second retaining member 9 to the respective parapet rail 7 in the working condition, said means being integral with the second retaining member 9.
  • the locking means 12 and 4 comprise a hole 13 which passes through the second retaining member 9 and which, when the second retaining member 9 swings relative to the tubular upright 4, can be oriented in such a way as to align it coaxially with the long anchoring elements 5 of the parapet 1.
  • the barrier 3 in the form of a framework, is also equipped with coupling means, labelled 14 in their entirety, mounted at a pair of sides parallel to the tubular upright 4, said coupling means 14 being designed to enable one barrier 3 to be joined continuously with another barrier 3 to lengthen it in such a way as to create extended accident prevention protection systems like the one shown by way of example in Figure 4 .
  • FIGS 6 and 9 show that the coupling means 14 more specifically comprise coupling protrusions 15 and matching cavities 16 which fit into each other in the plane in which the barrier 3 lies.
  • the protrusions 15 have through holes 17 made in them, which are aligned along a shared axis when the protrusions 15 and cavities 16 of two consecutive barriers 3 are fitted into each other: a rod-shaped element 18 can then be inserted into the holes 17 in the respective protrusions 15 on the two barriers 3 in such a way as to structurally join one barrier 3 to another barrier 3 following it (see also Figure 7 ).
  • the barriers 3 are joined continuously with one another. It is, however, obvious that the parapets 1 according to the invention may also be used to form discontinuous barriers 3, though placed one after the other; as well as barriers 3 which are both discontinuous and interconnected, arranged in such a way as to converge at right angles or at any other angle to one another.
  • the rod-shaped element 18 may be embodied by a single long anchoring element 5, obviously if the anchoring elements 5 are located round the edge of the building structure 2 at intervals equal to, or a multiple of, the length of the barriers 3. If this is not the case, the element 18 may be embodied by another, independent rod, that is inserted into the aligned holes 17 in the coupling protrusions 15 in such a way as to join consecutive barriers 3 of the parapet 1.
  • Figure 8 shows a sequence of steps, labelled A to E in the erection of a modular parapet 1 according to the invention.
  • the first step is to take a tubular upright 4 and position it in such a way that the pivotally-mounted second retaining member 9 vertically substantially overlaps the first, fixed retaining member 8.
  • the tubular upright 4 is then slipped onto a corresponding long anchoring element 5 and moved down coaxially along the anchoring element 5 towards the structure 2.
  • the downward movement is permitted until the position of the tubular upright 4 relative to the through hole 13 in the mobile retaining member 9 is such that further movement of the upright 4 relative to the fixed anchoring element 5 is prevented and the upright 4 is locked in place on the anchoring element 5.
  • This interference fit is shown in Figure 5 , from which it may be inferred that the interference fit is the direct result of the angle of the pivotally-mounted retaining member 9 relative to the fixed retaining member 8 which causes the anchoring element 5 to be locked against the hole 13.
  • This step causes the second member 9 to snap the barrier 3 firmly into place - opposing the reaction of the first, fixed member - thus holding it securely on the upright 4.
  • the upright 4 can continue to slide ( Figure 8E ) so that the entire parapet 1 can move finally until it reaches the structure 2 below. Erection of the parapet 1 is thus completed.
  • the special design of the means 6 or 8 and 9 of the barrier 3, while locking the barrier 3 to the respective upright 4, allows the barrier 3 to be slid lengthways along the rails 7 in order to correct assembling mistakes and/or compensate for any errors in the positioning of the long anchoring elements 5.
  • This feature makes it possible to overcome the problems, difficulties and limitations encountered during erection as a consequence of possible irregularities during the step of placing of the anchoring elements 5. At the same time, it offers a great advantage during the completing step of placing the anchoring elements 5, making it possible to choose the most convenient positions without being bound by mandatory spacing specifications requiring the anchoring elements 5 to be placed at exactly regular intervals.
  • the parapet according to the invention thus provides an accident prevention system that not only meets stringent safety regulations and requirements but can also be quickly and easily erected and dismantled, without tools, even by personnel without special skills.
  • the parapet provided can be attached to the anchoring elements on the building structure extremely easily and without limitations of any kind, even if the spacing of the anchoring elements varies from one structure to another or is not perfectly regular.
  • Another advantage of the parapet according to the invention is that it can be used to erect protection systems of any length and including parts at an angle to each other, where the angle can be of any required size.
  • parts of the protection system can be made by overlapping the parapets.
