Definitions

  • the object of the invention is to produce, using prestressed reinforced concrete beams with an open U-section, structures intended to cover large areas usable in the industrial and commercial field.
  • One of the main characteristics of the beams intended for the implementation of the method according to the invention consists in achieving the production of openings for a minimal bulk in the stacking and transport, and in being able to receive on the job. a series of cooperating juxtaposed sails which can be transported separately.
  • the beams targeted by the invention can be coupled to light sheet roofing structures with a vaulted profile which bear on the ends of the wings of the cooperating sails, or they can also be coupled to roofing sails made of vibrated reinforced cement at shaped profile.
  • the heads of the beam are constructed in a thickness greater than that of the beam in order to anchor the post-tensioned steel cables threaded in the holes of the heads.
  • a U-shaped beam can be made in different heights by keeping the same flange 1 and coupling it to suitably profiled sails 2, 3 and 4 of different widths, over which the layer of insulation and waterproofing.
  • the particular embedding coupling 5 established between the veil and the beam transforms the latter into a beam of the killer into a box having a very high inertia, so as to allow covering even large spans.
  • the open beam of smaller height, can also be produced in the form of a "shell" 6 by offering similar services.
  • the heads of the beam are formed by two "pins" of the same shape, but with an enlarged section of the wings (FIG. 2) inwards and they comprise two series of holes 7 through which the post-tension cables can pass which can be anchored to the keyboards. In this way, because the cables pass inside the U-beam and rest against the wings of this beam, they are protected, in the event of a fire, by the thickness of the continuous walls of the beam. .
  • FIGS. 3, 4 and 5 The on-site composition system of the beams is represented in the different phases by FIGS. 3, 4 and 5, in which we note respectively the assembly of the keyboards 8 and 9 to the central beam 10, the installation of the sails 11 juxtaposed and the post-tensioning of the cables to carry out the prestressing of the beam thus obtained.
  • FIG. 6 finally represents the positioning of the beam resting on the head pillars 12.
  • the height of the pillar 15 (FIG. 11) is obtained by the superposition of several prefabricated shell elements, opposite face to face.
  • the keyboards 16 which constitute the heads of the beam can be personalized in different ways, including with aesthetic functions, and they make it possible inter alia to accommodate different building service installations.
  • the roofing of the building can be achieved by interposing between the beams of the sails 17 of vibrated reinforced cement with shaped profile ( Figure 12), or vault elements having a light structure made of corrugated sheet 18 suitably insulated and self-supporting.
  • the beams described including those in the form of a shell 19 as shown in FIG. 14, coupled to sails of suitably profiled vibrated reinforced cement and comprising one wing raised with respect to the other, to provide the vacuum used to receive the transparent, vetical or inclined panels, sawtooth glazed roofs or sheds.
  • the structures produced with the method according to the invention make it possible to cover large free spaces in the industrial and commercial field while still offering excellent technological services.
  • the cooperating sails advantageously have a maximum width of 2.5 m.
