Definitions

  • This invention describes a bar, normally of a circular type, intended for acting as a reinforcement in forming reinforced concrete, made by pultrusion with polymeric materials which have a good performance under compressive stresses and also stand up well to the effect of fire on items of concrete reinforced with this material.
  • This invention is for application in the field of building in general and in particular in structures built by the sea, in structures subject to other aggressive agents, such as sewage treatment plants, petrochemical plants, in installations which require low electrical conductivity, such as conduits for electrical installations or in zones where low magnetic and radio-frequency permeability is needed, in which case its use is feasible through not causing shielding for communication and telephony equipment; and for all kinds of roads, railways, bridges and in general foundations for all kinds of constructions where the two main qualities of this material, such as corrosion resistance and heat insulation are required.
  • Plastics reinforced with fibres or composites were used for the first time in reinforcing reinforced concrete structures in the mid-nineteen-fifties and from then until now they have continued to be used as reinforcement systems in concrete structures.
  • the development and improvement of the manufacturing methods means that other applications have emerged, such as their use for reinforcing concrete structures, which have been based on the experiments and results obtained from their use as structural reinforcement.
  • This type of reinforcements from the beginnings until now, have been carried out with the stratification of fabrics or through sticking plates or sheets of these materials onto the outer parts of the items to be reinforced.
  • the pultrusion bar or round bar intended to be used as reinforcement for concrete comprises at least three differentiated zones:
  • the bar intended for working under compression and under the effect of fire loads is made by means of the fabric which is located in the second zone, which manages to bind together the fibres of the longitudinal reinforcements of threads or bundles of fibres located in the first zone, preventing the possibility of local buckling of the fibres in turn due to the larger amount of fibres existing in this second zone and the situation of the weft of the fabric, ensuring thermal protection of the central core which gives it greater strength under the effect of external heat loads.
  • FIG. 1 represents a longitudinal section of a bar reinforced with fibres for reinforcing concrete, as the subject of this invention.
  • FIG. 2 represents the cross-section of a bar reinforced with fibres for reinforcing concrete, as the subject of this invention.
  • FIG. 3 represents a view of one of the finishes of the bar, in which one can observe that this is made up of two types of fabric— 1 - 1 ′ and 2 - 2 ′, arranged in such a way that these form a mesh of glass covering the whole surface, acting as a mantle and providing a band to bind the longitudinal fibres existing in the central zone.
  • FIG. 4 represents a view of another finish of the bar reinforced with fibres, which in this case is made up of a single fabric which envelops the central core in a dual layer.
  • the fibre-reinforced bar for reinforcing concrete covered by this invention consists at least of:
  • FIG. 2 shows the cross-section of the bar reinforced with fibres for reinforcing concrete covered by this invention.
  • FIG. 3 represents one of the types of finish of the second zone ( 2 ) where the finish is made by means of two fabrics ( 1 and 1 ′) and ( 2 and 2 ′), where the first of these rotates anti-clockwise.
  • the weft ( 4 ) and the warp ( 3 ) in these fabrics where the warp ( 3 ) lies in parallel to the bundles of glass fibre and the weft ( 4 ) is normal to these.
  • the type of fabric used is a taffeta, with a weft whose filaments have the same width as that of the warp ( 3 ) and which beside this cover the whole surface in several layers, acting practically as a glass fibre mantle and ensuring the binding of the bundles in the first zone ( 1 ) by means of the weft.
  • FIG. 4 represents another type of finish of the second zone ( 2 ) of FIG. 1 ), similar and with the same functions as the one indicated in FIG. 3 , although using a single fabric which envelops the central core ( 1 ) of FIG. 1 ) in a double layer, ensuring greater transversal coercion in this case.
