Definitions

  • the present invention relates to metal load-bearing beams and columns for mixed steel/concrete structures and envisages suitable confinement of the critical sections of the reinforced-concrete structures by means of the provision of a closed section such as that shown in the accompanying drawings.
  • the object of the present invention is therefore to devise a method for adapting beams on-site in an easy and rapid manner as well as provide a metal telescopic beam for implementing this method.
  • This object is achieved by the present invention by means of a method for modifying on-site the length of metal beams for mixed steel/concrete structures, characterized in that the individual main beams are associated with relatively short beam sections or with bracket-type supports and are able to slide telescopically with respect to said sections or, by means of said supports rigidly connected to and hinged with the vertical structure forming the core of the columns, are able to be positioned at variable distances with respect to the support pillar; said beam sections and/or said supports are provided at the end with means for rapidly securing them to the pillar and/or to the opposite beam section.
  • the pillars are designed to form a robust and stable framework able to ensure rapid and secure assembly and support their own weight and the weight of the cast concrete for completing the structure, so as to obtain a mixed steel/concrete structure which also has a suitable fire-resistance.
  • 1 denotes a metal load-bearing pillar and 2 denotes four beams which are cross-fastened to said pillar.
  • Metal angle-pieces are welded in the zone of the pillar 1 where the beams 2 are placed and supported, along the internal perimeter of the pillar 1.
  • the flanges of these angle-pieces 3 projecting in the manner of a bracket towards the inside of the pillar 1 are provided with threaded through-holes inside which bolts 4 provided with a counter-nut 5, intended for the purposes described below, are screwed.
  • Beam sections 2' are mounted in a telescopically slidable manner inside the beams 2.
  • the beam sections 2' have welded (or otherwise fastened) at their end four bolts 6 and have welded on their underside a strip member 7 with a thickness such as to raise the support base of these beams to the same level as the bottom part 2" of the beams 2.
  • the strip members 7 are arranged on the ends of pairs of bolts 4 which, by means of screwing or unscrewing, allow perfect levelling adjustment of the beams 2',2.
  • the beams 2 have on their upper side strip members 2"' which have the purpose of guiding the beam sections 2' so as to limit any heightwise play of the telescopic beam sections 2'.
  • the beams and pylon may be provided with suitable disposable formwork for containing the casting, forming valid elements for reducing the energy consumption.
  • an angular support 9 formed by a bracket 109 and a pair of tie-rods 209 is provided.
  • This bracket 109 is hinged on the pylon 1 by means of a pin 10 which allows rotation thereof towards said pylon 1 through about 90°.
  • This support 9 is shown, on the left of the pylon when viewing the figure, in the lowered position and, on the right and frontally with respect to the pylon, in a position rotated upwards with the bracket 9 horizontal.
  • each tie-rod 209 has a pin 11 for positioning against the wall of the pylon 1 (see the bracket 9 shown on the right of this pylon 1).
  • tie-rods 209 of each support 9 are fixed to the pylon 1 by means of the pins 13.
  • the beam 2 instead is placed on the bracket 109 once the support 9 is in the operative position, i.e. rotated through 90° upwards and with this bracket in the horizontal position.
  • This beam 109 may be placed on this bracket 109 in a position at a varying distance from the pylon 1 and is fixed thereto by means of adjustable pins 12 which - see for example the pin 12' - have a stem 112 with a certain length and are provided between the beam 2 and the pylon 1 with a pair of nuts 212 which allow a certain adjustment of the length thereof, i.e. the distance between beam 2 and pylon 1.
  • the telescopic feature of the present beam is therefore, in this constructional variant, achieved by means of variable distance positioning of said beam 2 on said bracket.
