Definitions

  • the present invention relates to the building sector, and in particular to the scaffolding that is temporarily erected up against buildings during construction and/or maintenance operations.
  • the latter system is widely used on account of the ease and speed of assembly, and is made up of three main elements: the prefabricated frame; the braces, arranged laterally, either in a horizontal direction or in a diagonal direction, between one frame and another; and the metal boards, which form the treading surface for the workers.
  • a problem known in the sector is represented by the fact that, in order to carry out work at heights different from the pre-set ones that are determined by the difference in height between one treading surface and the immediately overlying or underlying one, it is necessary to resort to makeshift supports resting directly on the existing treading surface, to the prejudice of safety standards governing working environments.
  • a possible alternative for providing workers with an additional treading surface set at any height between the normal treading surfaces of the scaffolding itself would be that of applying to the uprights of the frames Innocenti-type tubes fixed in a known way with the corresponding clamps.
  • a first problem is represented by the fact that the encumbrance of the clamps of the Innocenti tubes is such as not to allow proper positioning of the boards that make up the treading surface, which have a pre-set width and would interfere with the fixing bolts of the clamps themselves.
  • a second problem is represented by the fact that, using said Innocenti tubes arranged in a direction transverse to the scaffold, the boards resting thereon would be misaligned vertically with respect to the boards of the normal overlying and underlying treading surfaces installed in the usual way on the frames of the scaffold itself.
  • a third problem consists in the fact that, if the scaffolding is erected up against the facade of a building, it may be difficult or even impossible to tighten some of the bolts of the Innocenti clamps because the wrench can interfere, in its movement, with the facade itself.
  • the main purpose of the present invention is to overcome the above problems, enabling provision of at least one removable treading surface, which can be installed at any height between the treading surfaces of the currently existing scaffold of the prefabricated-frame type.
  • a horizontal member of appropriate length which is provided with end fixing means designed not to interfere with laying of the well-known metal boards for providing the treading surfaces of scaffolding.
  • Said horizontal member has a length such that it can be fixed horizontally to the uprights of one and the same frame or to the uprights of two adjacent frames.
  • the horizontal member TR is basically constituted by a horizontal stretch of Innocenti tube of the same diameter as the tubes making up the frames, which is provided, at its ends, with two Innocenti-type clamps M designed to be constrained to the uprights or standards of at least one frame T of the scaffolding, via purposely provided bolts B.
  • saidbolts are positioned so that, oncetightened, they do not interfere with the laying of the boards A that make up the treading surface at the desired height.
  • a second peculiar characteristic of the invention lies in the fact that said bolts B of the end clamps M of the horizontal member TR are pre-arranged so as to enable the workers to tighten/loosen them while they are within the scaffolding so that the horizontal member TR that is described will be conveniently installed on/removed from the scaffolding itself without interfering with the wall of the building up against which the scaffolding is set.
  • Said end clamps M are substantially similar to the Innocenti end couplers, commonly used for joining two tubes to one another.
  • the horizontal member TR has a length corresponding to the distance I1 between the axes of the vertical uprights 5 of a standard frame T, which is 1.05 m.
  • a horizontal member TR to be set between two adjacent frames T of the scaffolding: in this case, the horizontal member TR is set parallel to the scaffolding 10 and has a length corresponding to the distance between the axes 12 of the vertical uprights of two adjacent standard frames T, which is 1.80 m.
  • the invention provides the maximum versatility, enabling provision of said additional treading surfaces, which can be positioned according to the specific requirements of intervention, having available substantially the entire height of the frames T between one treading surface and another.
  • each horizontal member TR can be installed exactly underneath the horizontal element of the frame T to which it is fixed, it enables additional treading surfaces to be provided that are exactly aligned with the existing ones either above or below the latter, thus eliminating the danger of the workers that use them from putting their foot wrong.
