Definitions

  • the present invention relates to the construction of masonry in general, as for example retaining walls, foundation walls, load bearing elements, external walls, breastworks and the like, made of reinforced concrete.
  • the present invention provides a reinforced masonry formed with prefabricated reinforced concrete slabs, installed in pairs and spaced to delimit a hollow space containing the finishing concrete casting, characterized in that said slabs are provided with reinforcements partially projecting from a face thereof to be mutually tied by straight steel bars, alternatively inserted into one and into the other reinforcement of said opposed slabs.
  • said reinforcements are flat trellis reinforcements, consisting of two straight longitudinal rods connected to a continuous zigzag rod alternatively welded thereto.
  • slabs forming said masonry may be lined on their face opposite to that from which said reinforcements are projecting.
  • the two prefabricated symmetrical slabs L for forming the masonry, are made of reinforced concrete 1 with trellis reinforcements 2 inserted by about one half into the concrete, while the other half projects from the inner face of the slab, the outer face of which may be provided with a layer 3 of general coating which, when the masonry is complete, is apt to form its facade.
  • the slabs are placed one in front of the other, in a vertical position, and they are sufficiently spaced to avoid any confusion of superpositions in the drawing.
  • the section reported on the sheet plane is the typical one corresponding to one of the planes on which the reinforcements are arranged, said reinforcements repeating themselves depthwise several times, exactly the same and parallel at an even distance.
  • the said reinforcements 2 are in the form of a flat trellis, consisting of two straight longitudinal round rods 6, connected to a continuous zigzag constant pitch round rod 5, alternatively welded thereto.
  • the reinforced concrete part 1 of the prefabricated slabs is shown in dashed lines.
  • the close positioning of the slabs is foreseen by the installation technique in order to be able to easily position in sequence, according to the development of the masonry and operating on the sides of the pairs of slabs, an adequate number of bars for taking the thrust of the concrete casting, proportioning said bars according to the case.
  • Figure 3 shows the same slabs of figure 2, slightly more spaced one from the other in order to be able to connect them by means of six bars 4.
  • Figure 3 also shows the concrete filling casting 7 while being executed.
  • Said casting 7, eventually lightened for insulating purposes, is represented by dotted lines, poured from the top to fill the bottom of the hollow space lying between the slabs. These are now spaced as far as required for forming the masonry structure being erected.
  • this positioning forms the limit within which the prefabricated slabs are allowed to move away one from the other under the thrust deriving from the fluid concrete casting 7.
  • the filling of the hollow space, closed on the heads may thus continue up to reaching the height of the slabs.
  • the prefabricated slabs 1 - acting as expendable forms (in that they remain in the structure as forming part thereof) - constitute the two faces of the structure itself.
  • the ties start to act when, under the thrust of the casting, the inserted bars take the shearing stresses between the reinforcement rods of both slabs, tending in opposite directions, which rods. find themselves adjacent as - during prefabrication - the trellises projectihg from the slabs have been appropriately positioned to coincide during assembly.
  • the masonry with a certain development is erected by placing side by side a sequence of segments formed by pairs of prefabricated slabs.
  • both the reinforcements arranged during prefabrication of the slabs, and the rods inserted during installation jointly form an organic design of final reinforcement, which is particularly valid for reinforced concrete masonry and also perfectly apt to withstand seismic shakes.
  • the known techniques provide, in some cases, for the insertion of additional reinforcement rods - during installation - into the reinforcements of prefabricated components, for the erection of reinforced concrete structures. Nevertheless, there is a substantial difference between these techniques and the object of the present invention, in that - up to date - such reinforcements have always been inserted for the mere purpose of taking the stresses proper to the finished structure (after the concrete of the finishing casting has reached the required curing), but never with the object of taking the thrusts produced by concrete at the fluid state onto the inner faces of the prefabricated slabs as expendable forms.
  • the structure and prefabricated slabs according to the present invention allow to eliminate the aforementioned drawbacks on account of the double function performed by the reinforcements of the prefabricated slabs in conjunction with the connection bars.
  • the concrete casting when the concrete casting is at the fluid state, they have the function of taking the thrust of said casting, without requiring any through tie-rods or external supporting structures for the prefabricated slabs. Later, when the concrete of the casting has stiffened, they also have the function of taking the stresses for which the masonry structure was designed.
  • ribs can be created in correspondence of the trellis reinforcements 2 while, in correspondence of the surface gaps between said ribs, it is possible to insert hollow clay blocks or to lay down panels of insulating material, as panels of wood and cement mixture or panels of "betongas" and foam cement.
  • the concrete casting 7, apt to fill the hollow space between the slabs 1, can be partly formed - for the same purpose - of light materials, as vermiculite or pumice or expanded clay.
  • the hollow space between the slabs could even be filled with loose insulating aggregates, possibly taking care to operate, in the accessible spots where the reinforcements are mutually connected, a closer tie with twisted wires and with hydraulic binders.
  • the present invention covers masonry formed with pairs of opposed prefabricated reinforced concrete slabs, provided with reinforcements partially projecting from a face thereof, which are tied (instead of simply by a plurality of straight steel bars, alternatively inserted into one and into the other of said interpenetrating reinforcements, as illustrated) by means of a trellis interposed between said projecting reinforcements and two pluralities of bars inserted between said trellis and each of said reinforcements.
