Definitions

  • the present invention relates to a prefabricated modular element for constructions or buildings with the features of the appended claim 1.
  • the purpose of the present model is to be advantageously and effectively used in the field of civil and/or industrial buildings, the description of which will make explicit reference without losing its general nature, for the construction of floor slabs and/or coverings in multifloor buildings with frame, wall, core supporting structure or mixed structure and the like, constructed both in wood and/or steel and/or masonry and in concrete and suitable to develop a suitable diaphragm behaviour with respect to horizontal loads and, furthermore, for the construction of vertical walls acting as vertical upwind frameworks.
  • Another object of the present model is to provide a prefabricated modular element which has a high intrinsic structural lightness and an application flexibility.
  • a further object of the present model is to provide a prefabricated modular element with optimum seismic-resistant features.
  • a further object of the present model is to provide a modular element with high environmental sustainability and which can be easily and quickly assembled and mounted.
  • E generally indicates a modular prefabricated element suitable to be used in the field of civil and/or industrial real estate.
  • Element E is suitable to define a constructive component with a structural and casing function obtained by the joining of a panel made of wood to metallic profiles, preferably cold-formed channels in rectilinear axis steel having an open section.
  • the joining between the wooden panel and the metallic profiles is done by the use of mechanical devices of various types and structural adhesives.
  • the collaboration between the wood-based panel and the metallic profiles gives the so composed element strength and stiffness characteristics which are higher than the sum of the performance capabilities of the individual constituent frameworks.
  • the so-defined constructive component subject to bending for vertical loads, is able to ensure a carrying capacity of 25 or more times its weight, is advantageously used to realize both the horizontal structure such as floor slabs or coverings, and the vertical supporting walls.
  • the wooden panel may be provided with one or more openings and/or through or partial holes, and it is suitable to be fixed to the supporting structure of the building by connections arranged at the edges of the wooden panel and/or at the end of the aforementioned metallic profiles.
  • the peculiarities that distinguish the element E from a constructive point of view are: the collaboration developed between the metallic elements and the wooden element, with the creation of a composed two-dimensional steel-wooden system having high performance and lightness; the assembly of the constituent elements implemented taking suitably into account the different degree of constraint required to the system from the ends to the centreline section, with the consequent reduction of joints used to transfer the composed action on the individual constituent frameworks; the pre-processing of the individual composing elements which, on the one hand, involves the construction of customized metallic beams wherein some parts of the connection system are integrated and, on the other hand, the preparation of the wooden-based panel with the creation of holes or cavities having variable number and shape depending on the mechanical performance to be achieve.
  • the element E comprises, in the upper part, a wooden panel 1 in "XLAM" (plywood made of hardwood board having crossed layers) and two steel collaborating beams 2 and 2' jointly arranged below the wooden panel 1, as better specified hereinafter.
  • XLAM wood made of hardwood board having crossed layers
  • the panel 1 is defined by several layers, preferably five layers, crossed and glued together of fir-wooden axes, with indicative dimensions of 2400 x 6000 mm and an indicative thickness of 85 mm.
  • perforated pockets 3 having indicative dimensions of 20 x 150 mm with an indicative depth of 80 mm.
  • Each beam 2,2' is made of two shaped press-formed made of steel or equivalent material which are welded together to form a single "omega" profile.
  • the base material is, preferably but not limited to, a 4 mm thick steel sheet having the S 355 JR quality.
  • the coupling and the folding of such sheets are designed to create a supporting surface for the soffit of the wooden panel 1, exposing, at the same time, blades 4 having a dimension of about 70 x 140 mm on the top of the shaped elements, on both sides of the shaped elements themselves.
  • the blades 4 are perforated with a plurality of holes, preferably but not limited to eighteen holes with ⁇ 14 mm and, on the same blades 4, it is provided the mechanical fixing of spacer rivets.
  • the so-made steel beams 2 and 2' are then hot galvanized.
