  • the present invention relates to the field of construction systems for civil works, and more in particular it refers to a modular block for civil works, particularly but not exclusively useful in the production of subgrades.
  • the present invention also relates to a composable modular system for civil works using the aforesaid block.
  • a combination of structures are generally used, which can be constructed in different materials, such as lime, concrete, reinforced concrete, metals, artificial or natural stone material, plastic materials.
  • Typical subgrades are produced through the creation of several layers of stone materials of different type, which allow drainage but do not guarantee static load capacity or any necessary aeration of the subgrade structure.
  • none of these types of subgrade adapt well to being combined with other structures, such as piping, electricity conduits, electro welded mesh for producing layers of concrete, etc..
  • these types of subgrade are particularly onerous in terms of installation times, both in the case of layers of stone material (the arrangement of which requires a certain experience in the distribution of the material and use of suitable machinery for compaction), and in the case of the use of bricks (which are generally heavy and poorly aggregated except simply by placing side by side).
  • modules or artificial blocks that in combination with one another allow walls or side retaining banks for slopes, embankments, etc., or actual artificial surface banks for the growth of vegetation.
  • modules are, for example, described in the patents US 6,543,969 and WO 03/076727. These modules have the sole function of laterally containing the forces of an embankment or as support for the growth of vegetation and cannot therefore be used as subgrades, as they do not have adequate structural and functional characteristics.
  • the object of the present invention is to provide a modular block for civil works that solves the aforesaid drawbacks and, more in particular, that is capable of being assembled with similar blocks in a simple and rapid way and that adapts well to other structures to be arranged or produced in the installation site.

  • the modular block comprises at least two structural protrusions spaced from each other for delimiting space defining opposite portions of the part of channel.
  • the block according to the invention allows composition of complex structures that are: a) particularly stable due to the presence of interconnecting means, b) resistant to high loads due to the structural protrusions and, c) provided with characteristics of aeration and drainage due to the combination of protrusions which, one close to the other, define one or preferably more channels. Besides the circulation of air and passage of water, these channels also allow any necessary arrangement of reinforcing material, the arrangement of hydraulic piping or electricity conduits, the arrangement of electro welded mesh and of yet other structures.

  • the block is arranged in place it has on its vertical other blocks, soil or pavement, completely superimposed on the block (see in particular Figs. 11 to 15).
  • the block has a base body 11, with a square base shape, formed by a flat central portion HA and four side ledges HB which develop from the periphery of the central portion 1 IA in a direction substantially orthogonal thereto, in practice defining the side edge of the base body 11.
  • Structural protrusions 12 (four in this example) develop from the flat central portion HA, in the same direction of development of the ledges HB.
  • these protrusion 12 are arranged on the base body 11 according to a matrix configuration 2x2.
  • each structural protrusion is formed by a central turret 12A and stiffening side bastions 12B arranged on opposite sides of the turret.

  • the end face of each protrusion 12 is substantially flat and parallel to the flat central portion 1 IA.
  • the block 10 consists of a shell in a single piece made of a molded plastic material.
  • the shell structure that is, a non massive structure that develops mainly inside a given interval of thickness, allows the weight of the block to be significantly limited, without prejudice to the structural strength, in the direction of development of the protrusions 12.
  • each protrusion 12 is in practice a bowl-like body with edges integral with the base body 11.
  • the bowl -like body is flared, thus allowing vertical stacking of blocks for storage thereof (structural protrusions that are arranged inside the cavities of protrusions above).
  • the bastions 12B are not massive in thickness.
  • the protrusions 12 develop orthogonal to the flat central portion HA, which acts as support for the module or for blocks that can be superimposed thereon (see for example Figs. 4, 11-15).
  • the block is preferably arranged so that the flat portion HA is substantially horizontal and the protrusions 12 are substantially vertical.
  • stiffening ribs HC are arranged between the ledges HB of the base body 11 and the sides of the protrusions facing these ledges.
  • Analogous ribs HC are also arranged between the sides of the protrusions, in their base area.
  • the transverse width of said space Sl is substantially equal to half the distance S2 between two adjacent structural protrusions 12 for defining part of said channel (in this way, as will be more apparent below, when two blocks are placed side by side, the distance between the protrusions of one block will be equal to the distance between the boundary protrusions of the two blocks, as is visible in Fig. 4).
  • each pair of side by side protrusions 12 defines opposite portions of a part of a channel. These channels C are delimitated by sides of the structural protrusions, so that they are also formed between the outer protrusions of two blocks when these are arranged side by side.
  • the matrix distribution of the structural protrusions 12 ensures that once the blocks are arranged side by side, a network of channels that cross one another orthogonally is formed. As the block is arranged in place according to a horizontal development, that is, with the fiat supporting portion HA arranged horizontally, the channels C are substantially horizontal.
  • blocks 10 cohere better, these are provided with interconnecting means 14 to analogous blocks or different blocks, albeit belonging to the same modular system.
  • interconnection between modular blocks preferably takes place according to an interconnecting direction concordant to the direction of development of the structural protrusions 12, that is, according to a coupling direction between blocks parallel to the direction of development of the protrusions.
  • interconnecting means 14 comprise, for example, for each structural protrusion 12, an alternating series of holes 15A and appendices 15B that develops, at the face of the flat central portion HA opposite the one from which the protuberances 12 develop, around the axis of development of this protrusion (12). More in particular, in this example, this series is provided with two holes 15A and two appendices 15B arranged alternating at the corners of the edge of the cavities 12C of the protrusion 12. As is clearly visible in Fig. 4, the appendices 15B of a first block are designed for coupling with the holes 15A of series of appendices and holes present on the further blocks of the same modular system arranged turned over with respect to the first.
  • the blocks of the same modular system are coupled along the direction of the axes of the protrusions 12 to create structures of blocks in "layers" in which the blocks of each layer are turned over through 180° with respect to the blocks of the adjacent layers.
  • the aforesaid series of holes 15A and appendices 15B allow coupling of two blocks arranged opposite each other with the faces of the base bodies 11 that are one on top of the other.
  • the interconnecting means 14 also comprise means that allow coupling of the blocks according to a direction opposite that allowed by the series of holes/appendices
  • these means comprise, on the end face of each structural protrusion 12, a bore hole 16A or a protuberance 16B of a shape suitable for coupling with a seat equal to the bore hole 16A.
  • the arrangement of the bore-holes/protuberances 16A/16B on the ends of the structural protrusions is alternated, in the sense that two side by side structural protrusions have a bore hole and a protuberance respectively.
  • An example of coupling is shown in Fig. 4.
  • the protuberance 16B or the bore hole 16A of said interconnecting means 14 of a first block are suitable for coupling respectively with a bore hole 16A or a protuberance 16B present on the end face of the structural protrusions of the further block arranged turned over with respect to the first.
  • the bore holes 16A also allow drainage of any liquids that infiltrate the cavities 12C (it is understood that other drainage holes for liquids can also be provided).
  • the blocks 10 can be mutually composed according to a side by side arrangement of the base bodies 11 and by superimposition of further blocks so as to couple the lower blocks with the upper ones by interconnection according to a vertical direction (with reference to the accompanying drawings, it being possible also to compose them on inclined or parallel planes with respect to the vertical).
  • a layer of side by side blocks 10 can be coupled at the top with further blocks 10 according to a stacked arrangement, that is, upper blocks perfectly lined up on lower blocks, obviously with opposite orientation with respect to each other, as is visible in Figs. 12, 14 and 15.
  • the upper blocks can be arranged on the lower blocks according to a key arrangement, that is, with upper blocks overlapped astride of a pair of lower blocks, as is visible in Figs. 4 and 13.

  • variants of the blocks described above can include side interconnecting means of side by side blocks, such as interlocking couplings or simple male/female insertion.

  • Figs. 5, 6 and 7 show a second block analogous to the one described previously, indicated as a whole with 10'.
  • This second block varies with respect to the first in dimensions and in the number of structural protrusions (for simplicity, the reference numbers of the components of this second block 10' are the same as the first block 10).
  • the base body 11 has a square shape with side dimensions double those of the first block 10 and has sixteen protrusions 12 arranged according to a matrix configuration 4x4.

It is obvious that variants of the same block 10" can include the appendices/holes 15B/15A around the cavity 12C, on the flat portion 1 IA.
  • the three modular blocks 10', 10" and 10"' described form the modules of a composable modular system for civil work structures.

  • a modular system of this kind can also comprise modules of different dimensions, for example with a configuration with an odd number of protrusions (3x3 or 5x5 and relative multiples).

  • Fig. 12 shows an application for pavements similar to that described, in which the materials are substantially the same, but in which the structure of the blocks 10 consists of two superimposed layers, in which the upper layer is produced by stacking the upper blocks turned over on the lower blocks, with mating of appendices 16B and bore holes 16 A.
