Definitions

• the present invention relates to a method for making coating walls, in particular for integrating existing constructions and foundations, reinforcing masonry that has deteriorated, and setting a barrier to an embankment .
• BACKGROUND ART For coating operations, a known technique is to provide, in a position facing the surface to be coated, formwork supported only on the outside by particular anchoring structures and then to cast the concrete in the space delimited by said formwork. Once the concrete has hardened, the formwork must be dismantled, with consequent penalization in terms of the overall times and costs of the works carried out.
• a known technique is to fill and/or plaster existing walls and to raise additional walls up against existing constructions .
• the purpose of the present invention is to provide a method for making coating walls by casting concrete for filling, which will enable the drawbacks outlined above to be overcome in a simple and inexpensive way, in particular eliminating the need to use complex equipment and cranes for lifting.
• a method for making coating walls characterized in that it comprises the steps of: forming a plurality of horizontal layers of panels set on top of one another starting from a base surface and facing a surface to be coated; and - filling the space between said panels and said surface to be coated by performing successive castings in order to make horizontal layers of concrete set on top of one another.
• FIGS. 1 and 2 are perspective views, which illustrate in part a preferred embodiment of the method for making coating walls according to the present invention
• - Figure 3 is a front view, at a reduced scale, which illustrates part of the method illustrated in Figures 1 and 2;
• FIG. 4 is a cross-sectional view according to the line IV-IV of Figure 3.
• Figure 5 is similar to Figure 4 and illustrates a different application of the method illustrated in Figures 1 to .
• the reference number 1 designates, as a whole, a wall for coating a vertical surface 2 defined by an existing wall .
• the wall 1 is made by constructing, first, a base 3 defining a base surface 4 and/or a horizontal positioning guide (not illustrated) and by forming, on the surface 4 or on the aforesaid guide, a horizontal row 5 of vertical, modular, rectangular panels 6, made preferably of concrete.
• the panels 6 are set in positions alongside one another and facing the surface 2 after construction of a metal supporting frame 8 has been started, by fixing a plurality of vertical uprights 9 to the base 3 in positions that are aligned and equidistant from one another.
• the panels 6 of the first horizontal row are stiffened and blocked by means of equipment of a known type (not illustrated herein) so as to form the self-supporting base for the panels that will be positioned on top, as is explained in greater detail in 5 what follows .
• the panels 6 have a height smaller than that of the uprights 9, define, along their own side edges, respective vertical grooves 10 and are slid into place from above, each one between a corresponding pair of
• the next step is the construction of the frame 8 by setting a row of horizontal cross members 12 for retention in a horizontal groove 13 made on the top edge
• each cross member 12 is anchored to the surface 2 by fixing a horizontal rail 15 to the surface 2 and by
• a first casting of concrete is then carried out in order to start to fill the space between the panels 6
• a horizontal row 20 of panels 19, which are the same as the panels 6, is formed.
• the row 20 is set on top of the row 5 by sliding a bottom terminal portion 21 of the panels 19 between the top ends 22 of the uprights 9.
• the construction of the frame 8 is then continued by piling a plurality of uprights 23, which form a prolongation of the uprights 9 between the panels 19 for a height such as to allow one top end 24 of the uprights 23 to project from a top edge 25 of the panels 19 and by arranging a row of horizontal retention cross members 26 along the top edge 25 itself in a manner similar to what was described above for the cross members 12.
• a second casting of concrete is carried out in order to form a second horizontal layer 27 of concrete, which is set on top of the layer 18 and has a top level comprised between the top edge 14 of the panels 6 and the top end 22 of the uprights 9.
• a plurality of uprights 31 is inserted from above between the panels 30 as prolongation of the uprights 23, and a row of cross members 32 is set along the top edge 33 of the panels 30 in a manner similar to what was described above for the
• a third casting of concrete is carried out in order to form a third horizontal layer 34 of concrete, which is set on top of the layer 27 and has a top level comprised between the top end 24 of the uprights 23 and
• the process can continue in a manner similar to what has been described above, making other rows of panels on top of the row 29 and performing successive castings of concrete in order to fill progressively the space between the surface 2 and the containment structure 36 constituted by the set of frames 8 and the panels.
• each casting of concrete could be carried out after two or more horizontal rows of panels, instead of just one, have been constrained to the surface 2 using the elements 16.
• Figure 4 illustrates a different application, which regards the coating of an embankment 38.
• the structure 36 remains separate from the embankment 38 in so far as it would be somewhat complex to fix the rails 15 in a stable and correct position.
• each layer of concrete holds a corresponding portion of the structure 36 in place and performs the function of support for the subsequent castings.
• the panels 6, 19, 30 are set at a particularly contained distance, for example 3 cm, from the surface 2 in so far as the panels 6, 19, 30 form an integral part of the wall 1 and do not require additional external supporting structures designed to be dismantled once the coating is completed.
• the frame 8 could be made in a way different from what is described herein. More specifically, horizontal spacer elements 16 could be bent downwards and not secured to vertical surface 2 so as they could remain embedded in the relative horizontal layer of concrete. In this way, it would be possible to improve the strength of the modular construction to the trust exerted on the panels by fresh concrete during casting.
• horizontal spacer elements 16 could be secured to anchoring members inserted in the concrete during casting.
