Definitions

  • the present invention relates to a composite precast slab for producing flooring for building low-rise or high-rise buildings, with the currently used depths, so that the flooring is perfectly flush with the beams, flat roof, as is usually required by architects and developers.
  • the precast slab meets the requirement of being self-supporting during the assembly operations and creation of the flooring to ensure a safe working platform for the workers, whilst also avoiding the need to use additional formwork for the safety thereof.
  • precast slab Its mechanical strength and fire resistance are suitable for the precast slab to be used in spans larger than those that are usual in residential properties, which are currently made using traditional in situ solutions or with prefabricated beam and block elements, also allowing the necessary spaces to be made for inserting installations without lessening the support features thereof.
  • the invention lies within the technical-industrial sector of construction.
  • the composite precast slab of the invention provides a perfect solution to the problems posed by the solutions of the prior art by proposing a solution that is simple, effective and functional, which makes it possible to build a lightweight self-supporting concrete floor for large spans with a smaller weight, much more flexible to adapt to different geometrical shapes, in spans and hollow spaces, and the mechanical requirements of the floor, and it is also possible to use different reinforcements.
  • the precast slab or prefabricated element consists of a lower concrete layer from which concrete ridges and reinforcements emerge, which are simultaneously situated in the prefabricated element itself.
  • the reinforcements can take the form of a lattice or another arrangement such as hoops, although in all cases they are simultaneously present in the prefabricated element.
  • the precast slab combines prestressed and reinforced elements in the same piece for both longitudinal flexure reinforcement and transverse shear reinforcement.
  • the reinforcement of the precast slab is positioned on the casting bed so that, when the prefabricated piece projects, it is perfectly secured thereto.
  • the area of reinforcement emerging from the prefabricated element can be adapted to each particular case in terms of height, width of the reinforced area, and/or diameter and capacity of the reinforcement that is embedded and emerges from the precast slab.
  • the number and arrangement of the ridges can vary in order to adapt it to each particular site, as can their specific shape, which can be straight or with the form of a compression head on top to improve the single-section mechanical characteristics.
  • the prefabricated element can have nonprestressed reinforcement for shear reinforcement in the concrete ridges emerging therefrom so that it may be used to increase the strength of the piece for special loads.
  • Said nonprestressed reinforcement can emerge through the top of the concrete ridge so that it can be used to improve the connection of the prefabricated concrete when poured on site.
  • the lower layer of concrete can optionally have welded-wire reinforcement or structural reinforcement.
  • the precast slab (1) of the invention comprises a relatively low, flat, elongated lower concrete layer or base (2) from which lateral concrete ridges (3) emerge in its end areas, and a ridge (4) in its central area of a considerably smaller height and greater width than that of the ridges (3).
  • a lattice reinforcement (5) of a similar height to that of the ridges (3) emerges from the central ridge (4) and is embedded in it and in the lower concrete layer (2) itself, consisting of a longitudinal reinforcement (6) positioned inside the precast slab (1), another longitudinal reinforcement (6') positioned outside the precast slab (1), and a transverse reinforcement (7) that joins and connects the others.
  • the precast slab (1) can be made without a central ridge (4), or rather its height can be zero and therefore the reinforcement (5) emerges directly from the lower base (2).
  • the reinforcement (5) is a lattice with a triangular form in its front view, as can be seen in figure 4.
  • the reinforcement (5) can take the form of a hoop or can be flat, or any other configuration with the same functionality or even a different height.
  • the lateral ridges (3) comprise a nonprestressed reinforcement to enable it to be used in shear reinforcement, reinforcement which can project from its section to improve the connection with the concrete poured on site.
  • the precast slab (1) can have a prestressed reinforcement (8) or a welded-wire reinforcement (9) in its lower concrete layer (2).
  • Figure 5 shows an example of floor made with the precast slab (1) that is the object of the invention. It is possible to see two examples of precast slab (1), wherein classic lightweight form elements (10) are positioned between the concrete ridges (3) and the reinforcement (5), the concrete (11) is poured on site to fill the free areas of the precast slab (1), particularly around the longitudinal reinforcement (5), a compression layer (12) is poured on site and a complementary reinforcement (13) is also installed on site, which consists of a welded-wire reinforcement and negative reinforcement.
  • classic lightweight form elements (10) are positioned between the concrete ridges (3) and the reinforcement (5)
  • the concrete (11) is poured on site to fill the free areas of the precast slab (1), particularly around the longitudinal reinforcement (5)
  • a compression layer (12) is poured on site
  • a complementary reinforcement (13) is also installed on site, which consists of a welded-wire reinforcement and negative reinforcement.
  • the lateral ridges have a projecting reinforcement and the at least one central ridge is made from concrete.
