Definitions

  • the present invention relates to a metal frame for embodying building structures made of reinforced concrete.
  • a typical configuration of the metal frame substantially provides for a complex of longitudinal steel rods interconnected by other transversal steel rods.
  • the frame is normally formed in the building yard by disposing the steel bars in the form according to the aforesaid configuration and binding them together with iron wire so as to prevent them from slipping during the reinforced concrete casting.
  • a proposal for remedying this situation is provided by mass producing the frames outside the building yards with an industrial process, thereafter transporting them to the building yards and assembling them, ready-for-use, in the related forms.
  • volumetric bulk does not facilitate the placing of the pre-formed frame into the form.
  • the object of the present invention is to provide a metal frame for reinforced concrete such as obviates the difficulties existing in the known art, as mentioned above.
  • Such purpose is fulfilled by embodying'a metal frame characterized by the fact that it comprises longitudinal rods and transversal rods reciprocally joined by articulated joints.
  • the frame according to the invention as illustrated, indicated generically by 10, comprises four parallel, rectilinear, rough-surfaced steel rods, indicated by 11, which will hereinafter be called length-members, articulated to a series of transversal steel rods (only three of which are illustrated) bent in the form of a closed ring, indicated by 12, which will hereinafter be called cross-members.
  • length-members 11 and cross-members 12 are effected by means of rings 13 consisting of arched or hooped sections of steel bars which are welded along each length-member 11 and through which pass the cross-members 12 as can be clearly seen in FIGURE 1.
  • the length-members 11 are rigidly restrained in pairs by a series of transversal bars 14 welded at their ends to two length-members 11 and another series of transversal bars 14 welded at their ends to the other two length-members 11.
  • the transversal bars 14 thus all have equal length, so as to keep the paired length-members parallel at the same distance for both the pairs.
  • the cross-members 12 are quadrangular in shape and the length of the transversal bars 14 is such that the pivoting between cross-members 12 and length-members 11 by means of the rings 13 is at the corners of the cross-members 12.
  • the frame 10 which has been described and illustrated can have its volumetric extension varied.
  • the pivoting provided enables the cross-members 12 to describe a rotation of 180° about their pivot- points, with a related oscillation of the two pairs of length-members 11, parallel-wise one to the other, between a distanced position and a juxtaposed position.
  • the frame 10 can be volume- manufactured outside the building yard by an industrial process.
  • the fact that the frame can be reduced in volume makes it possible to optimize the ratio between quantity of material transported and volume occupied.
  • FIGURE 2 In the building yard, in the folded-back configuration of FIGURE 2, it is very manageable and easy to place into the form. Once it has been so placed, it opens out into the operative configuration shown in FIGURE 1.
  • the frame 10 as illustrated is particularly indicated for the reinforcement of girders or beams or, in vertical configuration, of pillars.
  • longitudinal and transversal rods can in any case vary depending on the building structure to be reinforced, provided that the longitudinal rods and the transversal rods are reciprocally joined by means of articulated joints such as allow an articulation between them of a kind that will vary the volume of the frame.
  • FIGURE 3 shows a variant of the articulated joint.
  • This variant consists in the fact that, around each length-member 11, correspondingly to each cross-member 12, there is wound an iron wire 15 with a broader central turn which forms a ring 16 into which the cross-member 12 enters.
  • the surface roughness of the length-members 11 which is provided for in order to ensure that they have perfect adherence in the concrete, prevents any longitudinal slipping of the iron wires 15.
