Definitions

  • This descriptive fact sheet refers to an application corresponding to stirrups for the construction of rebar reinforcements for reinforced concrete beams which enables the negative round bars to be placed on the top horizontal bar of the stirrup.
  • This invention is to be applied in the construction industry, specifically in the manufacture of rebar reinforcements for reinforced concrete beams.
  • the habitual elements that make up the reinforcement for reinforced concrete beams are: the top longitudinal round bars nos. 1 and 2; the bottom longitudinal round bars nos. 3 and 4, the stirrups no. 5; the bottom reinforcement round bars nos. 6 and 7 and the round bars for absorbing the negative moments nos. 8 and 9, as illustrated in figure 1.
  • the drawing presented here is of a generic and non-exhaustive nature. When the reinforcements constructed according to this model are placed in situ, to position the negative round bars at the point determined by the calculation these must be shifted until placing them on the bottom part of the top horizontal transversal branch of the stirrups.
  • This invention proposes constructing the stirrups in a way that the top horizontal bar is shaped with high and low sections so that the top longitudinal round bars are placed on the high sections and the top of the negative round bars are supported on the low sections.
  • the vertical branches of the stirrups are anchored on the top longitudinal round bars above the round bars that cover the negative moments, meeting the conditions imposed by the shear and tangential stress calculation.
  • the negative moments bars can be placed above the horizontal part of the transversal reinforcement as illustrated in figure 2. This system reduces the cost of manufacturing the reinforcements.
  • This fact sheet refers to an invention patent application for the construction of rebar reinforcements for reinforced concrete beams using a type of stirrup that enables the negative round bars to be placed supported on the top part of the horizontal bar of the transversal reinforcement, whilst complying with the rules of the calculation for reinforced concrete as regards shear and tangential stress, thereby facilitating the placement in situ of the round bars for absorbing the negative moments as well as the construction in factory of the corresponding reinforcements.
  • the formwork of the beams is put in place and the reinforcements of the beams are supported on it. Subsequently, the round bars of the negative moments are supported on the top part of the reinforcements instead of initially having to introduce them into a reinforcement, run them inside the reinforcement until the end of the negative round bars and then shift them through the inside of the other reinforcement as far as the position determined by the calculation, finishing off with the task of tying or welding them one by one under the top horizontal bar of the stirrups.
