Definitions

  • the present invention relates to a prefabricated component for building staircases.
  • prefabricated components for building staircases has considerable limitations.
  • Prefabricated components currently in use are in fact very heavy and are therefore difficult to transport and complicated to install.
  • Said prefabricated components are furthermore unsuited for easy industrial production, since they must have different dimensions according to the construction requirements.
  • the aim of the present invention is to obviate these problems by providing a prefabricated component which allows to optimally build staircases, particularly facilitating the operations for transport and installation.
  • a further object of the present invention is to provide a component of the above described type which is simple in concept, has a low weight and great strength, and is versatile in use and relatively inexpensive.
  • the present prefabricated component for building staircases which is characterized in that it comprises a supporting element made of foamed plastic material which extends longitudinally and is cut in the shape of steps along one of its upper surfaces, said element being provided with a plurality of longitudinal holes intended for the insertion of respective metallic reinforcement frames and suitable to be filled, when installed, with a concrete casting, to produce respective beams for stiffening said supporting element.
  • a prefabricated component for building staircases is generally designated by the reference numeral 1.
  • the prefabricated component 1 is constituted by a supporting element 2 made of foamed material, such as polystyrene, which extends longitudinally and is cut in the shape of steps 3 along one of its upper surfaces. More particularly, the supporting element 2 is obtained from a piece of foamed material which is shaped like a parallelepiped and is cut in steps at the median plane by means of appropriate electronically-controlled devices suitable to vary as required the rise and tread dimensions of the steps 3. In practice, therefore, two mutually symmetrical supports of the above type are obtained simultaneously from a single piece of foamed material. This allows to maximally limit manufacturing waste, with optimum use of the material.
  • foamed material such as polystyrene
  • the lower surface of the support 2 which is meant to be inclined when installed, has a series of longitudinal grooves 4 which are arranged side by side so as to give a sort of undulated appearance to said surface.
  • the grooves 4 extend over the entire length of the component.
  • a plurality of openings 5 which extend longitudinally over the entire length of the component is furthermore defined at the lower surface of the support 2.
  • said openings 5 are defined at the median section and proximate to the sides of the supporting element 2.
  • the openings 5 extend along longitudinally vertical planes, and their cross-section has a central narrowing, so as to define insertion seats for respective reinforcement rods 6.
  • the openings 5 are in fact conveniently suitable to be filled, during the preparation of the prefabricated components, with a concrete casting so as to define beams for the reinforcement of the supporting element 2.
  • Said supporting element 2 is provided with a plurality of longitudinal holes 7 which are uniformly distributed along its transverse cross-section and extend parallel to the lower surface of said element.
  • Respective reinforcement beams are inserted in the holes 7 and are constituted by longitudinal rods 8 which are connected by brackets 9 on transverse planes; for example, the brackets 9 are folded in the shape of a triangle, and the rods 8 are arranged at the corners of said triangle.
  • the holes 7 are meant to be filled with a concrete casting when installed, as specified hereinafter.
  • the holes 7 are defined with a single cutting operation by means of said electronically-controlled devices. This operation therefore cuts respective slots 10 which are connected, on longitudinally vertical planes, to the upper surface of the support 2.
  • a pair of electrowelded metallic nets 11 and 12 with rectangular mesh is associated with the supporting element 2; said nets extend respectively at the upper step-like surface 3 and at the lower grooved surface.
  • the upper metallic net 11 is folded so as to follow the profile of the steps 3, whereas the lower metallic net 12 conveniently has its longitudinal rods arranged respectively at the grooves 4 of the support 2 (see figure 3).
  • the metallic nets 11 and 12 are mutually connected by means of iron elements 13 which are driven transversely through the narrow portions of the support 2 (see figure 2). Essentially, the metallic nets 11 and 12 form a sort of lattice in which the support 2 is interposed.
  • Further metallic nets 14 of the above type are furthermore associated with the sides of the support 2, at least on the sides of the staircase which are to possibly remain in view after installation.
  • the described component has a very low weight and can therefore be transported and installed very easily, without resorting to special equipment.
  • the component which defines a staircase of normal size can be easily carried manually and installed by two workers.
  • Respective beams for stiffening the component are thus defined and give adequate strength to the flight of stairs.
  • the surfaces of the component which are in view, particularly the lower and lateral surfaces, are then covered with an appropriate layer of plaster 15.
  • the metallic nets are embedded in said layer of plaster 15.
  • the upper step-like surface of the staircase is instead covered with an appropriate covering material 16.
  • the metallic nets associated with the supporting element 2 are furthermore suitable to spread the loads which act on the staircase.
  • said metallic nets are appropriately embedded in a layer of cement.
  • the described prefabricated component ultimately allows to optimally solve the problems linked with the building of staircases and the like, by virtue of the lightness and strength characteristics which facilitate its installation.
  • the prefabricated component furthermore lends itself to industrial production, since it can be manufactured so as to comply with the different constructive requirements.
  • the supporting element made of foamed material is in fact obviously cut to the required dimensions by means of appropriate instructions given to the automatic cutting devices, varying its extension and proportions.
  • the materials employed, as well as the shapes and dimensions, may be any according to the requirements.
