Definitions

  • This disclosure refers to building systems, more specifically to devices for use in building systems, precisely a metallic support for rigging formed by a bar including metallic supports for use in building industries.
  • the existing metallic options feature difficulties related to sustaining larger loads, aside from the high risk of damage to the support surface, since its structure is relatively fragile, susceptible to bending when subjected to common utilization efforts, and lacking any protection that prevent excessive contact of the metallic parts with the support surface of the slab.
  • Document MU8502688 teaches a plastic spacer used in building industry for positioning welded meshes or rigging in the manufacture of industrial floors or concrete paving with a wing-shaped building format, which leads to low manufacturing cost and renders excellent mechanical resistance, practical utilization and optimal transportation, storage and handling, since it allows accommodation of the pieces between each other.
  • Patent FR2944302 shows a metallic linkage element for meshes or metallic frames to be used in concrete frames, in order to obtain reinforced concrete slabs or horizontal walls.
  • Patent US4056908 explains the compound action of open-layer steel beams, providing support for beams and girders, and the reinforced connection of the concrete slab, where parts of the upper vortex of the steel beam layer protrude through the upper sections of the cross member rope and through the openings provided on the model of the metallic sheet place over said beams prior to the concrete pouring, and a continuous cylinder-shaped rod fixed near the tip of each flap element that protrudes in parallel to the longitudinal axis of the beam and a covered reinforcement wire mesh between the shafts.
  • Patent US5729949 shows a support for sustaining and spacing reinforcement bars, featuring a hollow tapered body for stacking, a flat base for support, an opening to allow the cement flow inside and around the support, and the notches on the upper surface of the support to hold the bars in the desired position.
  • This disclosure refers to a metallic support for rigging used in building industry, featuring an innovative forming that enables replacement of the current solutions with significant advantages in terms of mechanical resistance and easy operation.
  • the metallic supports serve for support of prestressing cables, negative reinforcements and structural fittings in a configuration where the metallic supports (2) are welded to the upper metallic bar (1), allowing easier execution of the assembly, compared to solutions commonly employed - the plastic support, since it dismisses the need for fixing all supports on the mesh through wire fastening or shaped nails, and subsequent fixation of the metallic bar on the plastic supports.
  • the metallic supports are more resistant than plastic supports, thus being safer, as they do not break after the concrete pouring, decreasing losses caused by damage during use or transportation.
  • the supports (2) have a semicircle or substantially rectangular shape with rounded edges and one open side, similar to, e.g., a "C", in which the dimensions of the bar (1) and the supports (2) vary according to the height to be provided by the set, which also affects the thickness of the supports (2) and the bar (1).
  • the curved shape e.g. a "C” shape, a parabolic shape, an arched shape, a semicircular shape, etc.
  • the curved shape e.g. a "C” shape, a parabolic shape, an arched shape, a semicircular shape, etc.
  • the support (2) allows increased mechanical resistance when compared to similar market versions, which are "V” shaped, in other words, by straight shafts welded to the steel bar.
  • the supports (2) are welded beneath the steel bar (1) with a preferable thickness of approximately 10 mm (where in other examples, the thickness may be about 5-15 mm, about 8-12 mm, about 10 mm or more, about 8 mm or more, or about 12 mm or less, or other sizes), but may be easily adapted for different uses with variable spacing along the entire bar or one or more portions of the bar, according to the load to be sustained, though normally around 400 mm (where in other examples, the supports may be spaced at least 400 mm apart, at least 300 mm apart, between about 350 and 450 mm, about 500 mm or less, 750 mm or more, or others). This distance between the supports (2) is established in order to prevent deformations on the support bar (1) upon assembly and concrete pouring; the support bar (1) is specified on an execution project of the prestressing service.
  • the support bar (1) has 3 meters length for easy transportation and application as per market practice, avoiding losses due to sectioning at the time of execution of the civil work.
  • the "C"-shaped bases of the support (2) may be painted with epoxy paint or coated with a plastic end sheet. This way, undesired marks on the slab or on the finished beam due to steel corrosion are avoided.
  • the metallic supports required may be identified by the desired height.
  • the supports are painted in different colors, for size distinction according to a color chart.
  • the launching of the rigging over the bars (1) may start, and then, the negative fittings after the rigging are fixed on the supports.
  • metallic hoops are used as supports
  • the use of metallic supports provided herein is more advantageous, as its welding fixation is safer and its base is coated with epoxy painting, which prevents any marks on the finished slab.
  • a metallic rigging support comprising: a metallic bar (1); a plurality of metallic supports (2) connected to the bar, wherein said supports (2) comprise an arched, semicircular, parabolic or substantially rectangular exterior shape defining an opening on the bottom of the support, and a plurality of lower ends on each side of the opening, wherein the supports are positioned in a spaced manner along said metallic bar (1), in order to provide proper support to each type of use provided for in a building project; and a plurality of protective elements on the lower ends.
  • the metallic rigging support wherein the plurality of supports are welded to the bar.
  • the metallic rigging support wherein the protective elements comprise a paint, a thermoplastic covering, or both.
  • the paint is an epoxy paint.
  • the metallic rigging support wherein the supports are regularly spaced along the metallic bar.
  • the metallic rigging support wherein the supports have rounded exterior edges.
  • the metallic rigging support wherein the exterior shape is substantially in the shape of a "C".
  • the metallic rigging support wherein the supports are spaced at least about 400 mm apart along the bar.
  • the metallic rigging support wherein the supports are spaced at least about 300 mm apart along the bar.
  • the metallic rigging support wherein the supports are spaced at least about 750 mm apart along the bar.
  • the metallic rigging support wherein the bar is about 3 meters or less in length.
  • a rigging system comprising one or more metallic rigging supports according to any of the embodiments of the first aspect.
  • a rigging system comprising one or more metallic rigging supports, further comprising a rigging fixed to the metallic rigging supports.
  • a rigging system comprising one or more metallic rigging supports, further comprising a concrete material poured around the one or more metallic rigging supports.
