Definitions

  • This invention relates to a system, method and modular forms for the production of floors.
  • floor in building generally identifies a flat structural element that covers a space and an area, transmits the loads to the structures or vertical walls around the area, through shearing stresses and flexure moments, and acts as joint between said structures or vertical walls.
  • Floors are traditionally made of joists or rather by a structure constituted by several prefabricated small joists, in concrete with iron reinforcements, which support special bricks called “hollow tiles” or “large hollow tiles”.
  • the above-mentioned reinforced joists are arranged in parallel and rested on beams integral with the two walls that face the area to cover.
  • the hollow tiles are laid in sequence between each pair of parallel joists that support them.
  • This configuration defines a plane, whose lower surface, that delimits the area from the top forming its ceiling, can be plastered or coated with a light masking (ceiling or false ceiling).
  • the upper surface of this plane, that can also be previously protected with an electrowelded wire mesh, is instead covered with a concrete cast and finished through the application of a suitable covering superstructure (tiles, parquet, etc.) to form the floor, that is a substantially smooth and solid resting surface able to withstand the weight of objects and/or people.
  • a first series of problems derives from the complex operations required to prepare the hollow flat layer, formed by joist and bricks, also due to the significant weight of these components.
  • These modular forms are configured in the shape of a spherical dome with four supports, connected to one another by means of an equivalent number of arches. Each arch has side edges that are designed to allow them to be joined with the edges of the adjacent modular forms in order to form a continuous structure.
  • the structure After the installation of an ordinary electrowelded wire mesh or iron rods on the extrados of the spherical crowns, the structure is covered with a concrete cast, which subsequently acquires the shape of a series of domes resting on parabolic arches and ending in correspondence of the contour on four pillars.
  • floor is indifferently used to designate both a surface to be supported by an underlying structure, that could also be the ground, and a structure able to cover a space supporting loads to be discharged to perimetric beams or walls.
  • floor will be used only with the second meaning, unless differently specified.
  • the invention aims at solving the above described problems that occur when roofs constructed with hollow tiles and joists or similar techniques are adopted.
  • the first scope of the invention is to describe a system, a method and modular forms suited to enable the preparation of ribbed floors in a simple, affordable, easy and quick manner.
  • the second scope of the invention is to describe a system, a method and modular forms for the definition of ribbed floors, that can effectively reduce the risk deriving from the breaking of components and facilitate their stocking.
  • the third scope of the invention is to define a system, a method and modular forms suited to produce lacunar ceilings in several aesthetic variants, also with crossed reinforcements.
  • the fourth scope of the invention is to define a system and a method for the preparation of ribbed floors based on reusable modular forms.
  • Part 1 of Fig. 1 generically represents a form of the first kind, produced in accordance with the requirements described in this invention. Form 1 can satisfactorily be produced in pure or recycled plastic.
  • Form 1 substantially represents a section in the shape of an inverted U, defined by a slightly convex upper wall 1A and by two side walls 1B that are slightly inclined outwards. The lower end of each of the side walls 1B forms a substantially flat edge 1D that is used for resting and connection purposes.
  • 1E identifies an appendix that stretches continuously along one of the longitudinal edges of walls 1A and 1B of form 1.
  • form 1 substantially has a quadrangular shape suitable for the definition of a central longitudinal cavity.
  • Fig. 2 shows a form of the second type described in the invention, generally referred to as 2 or form 2.
  • this form is constituted by a slightly convex upper wall 2A, by two side walls 2B, slightly inclined outwards, and by a bottom wall 2C, again slightly inclined outwards.
  • the lower end of each of the side walls 2B and 2C define edge 2D, used for resting and connection purposes, which is substantially flat and similar to edge 1D of Fig. 1.
  • form 2 substantially has a quadrangular base suitable for the definition of a central cavity which, unlike that of form 2, is not open on both sides but closed on one side by means of wall 2C.
  • Fig. 3 shows the principle used to assemble modular forms 1 and 2.
  • Forms are substantially assembled in sequence, in longitudinal direction through the insertion of the appendix 1E of form 1 into the central cavity of form 2.
  • the assembly then implies inserting into the cavity of the above-mentioned form 1 the appendix 1E of the next form 1, and so on.
  • the last form 1 of the series is then coupled to form 2, equipped with a suitable appendix, which is similar to appendix 1E and suited to be inserted in the central cavity of the last form 1 installed. It is evident that the sequential assembly of the central cavities of forms 1-2 enables to create a vault.
  • forms 1-2 are then assembled side by side so that edges 1D and 2D of forms 1 and 2 are coupled with the edges, shaped for this purpose, of the equivalent adjacent forms.
  • edges 1D and 2D of forms 1 and 2 are coupled with the edges, shaped for this purpose, of the equivalent adjacent forms.
  • the above-mentioned edges can be equipped with suitable reciprocal coupling devices of known design.
  • This procedure enables to define several parallel vaults, illustrated under letter C of Fig. 3, spaced by seats, illustrated under letter D, whose bases are formed by the coupled edges 1D and 2D of the adjacent forms 1 or 2.
  • Fig. 4 shows an example of floor based on the use of forms 1 and 2.
  • a traditional scaffolding of wood or equivalent material to form the structure that will act as temporary resting surface for forms 1-2.
  • This resting surface will be placed at the same height of the desired floor lower surface.
  • the opposed walls of the space will be equipped, at the same height, with resting beams, which are not shown in the figure because they are of traditional design, whose function will be described in the paragraphs that follow.
  • the resting surface will constitute the base for the forms assembled in accordance with the principle described in Fig. 3.
  • the number of the assembled forms 1-2 should obviously be suitable to create a structure with a length and width equivalent to that of the floor to be produced.
  • seats D is designed to hold the bars or iron rods described under number 3 of Fig. 4, which should be suitable to tolerate all the stresses indicated in project specifications.
  • the ends of these bars 3 will rest on the load-bearing beams, previously placed on the opposed walls of the space where the floor has to be laid and connected to said load-bearing beams according with the current praxis and rules. It is useful to notice that in the configuration referred to in the invention, the bars 3 do not rest on the upper surfaces of the edges 1D and 2D, but are separated by means of shims of traditional design.
  • a traditional electrowelded wire mesh illustrated under number 4 of Fig. 4, and possible iron rods for the absorption of negative moments, will be placed on the extrados, above the assembled modular forms 1-2.
  • the resulting structure with an appropriately delimited perimeter (constituted, for example by the same vertical walls of the area where the floor will be laid), is then used as a base for the concrete cast.
  • the casting is carried out using high resistance concrete, dosed in accordance with project specifications as schematically indicated under number 5 of Fig. 4.
  • the amount of concrete cast should be suitable to "cover" all the forms installed or rather to saturate all the seats D and to guarantee the presence of a specific amount of concrete even above the upper walls 1A and 10A of the forms and to also cover mesh 4.
  • forms 1-2 In order to allow the formation of the type of floor described above, with unidirectional parallel load-bearing ribs, which involves filling seats D with the related reinforcing elements 3, forms 1-2 must have a quadrangular or preferably a square or rectangular basis, with dimensions varying according to static requirements.
  • the standard size of the forms described could be such to have a distance between the centres of the load-bearing ribs of 50 - 60 cm,, and heights of 20, 24, 28 or 30 cm.
  • the length of each form can vary from a minimum size, that could be similar to the distance between said centres, to a maximum that may be limited only by the architectural requirements to be met during assembly.
  • forms 1-2 are assembled in sequence on-site in order to create the lightening cavities of the floor in reinforced concrete, constituted by vaults C, and assembled side by side in order to form seats D. After they have been reinforced with the iron rods 3 and filled with concrete, the seats D become ribs or beams suited to support the floor with light reinforcement (not pre-stretched iron rods), so that a ribbed reinforced concrete floor is obtained.
  • the configuration illustrated in Figures 1-4 also foresees a specific head form 2 that closes three sides of the lightening vaults C, which is used to close the concrete cast 5 next to the ends of the iron rods 3 of the above-described load-supporting beams.
  • Fig. 5 shows a second typology of forms, in accordance with this invention, that enables to produce floors with crossed load-bearing lacunar ribs.
  • the geometry of form 10 resembles that of a spherical dome with a quadrangular or more specifically a square basis. It is useful to notice that, for special applications, the geometry could also resemble that of a cylindrical dome with rectangular basis.
  • Fig. 5 also shows that form 10 is constituted by a slightly convex upper wall 10A and by four side walls 10B that are slightly inclined outwards.
  • the lower end of each of the side walls 10B defines a substantially flat resting and connection edge 10D.
  • the edges 10D When coupled with the edges of the adjacent forms 10, the edges 10D constitute the area that forms the base for the ribs that support the floor.
  • the standard dimension of the forms 10, measured along the external perimeter, can be, for example, equivalent to 50 x 50 cm or to 60 x 60 cm.
  • Standard heights can instead be equivalent to 20, 24, 28 or 30 cm. These heights will always be selected according to the laws in force, the span of the floors to be produced and obviously in function of possible special requirements. Basic and height dimensions may be freely selected by project engineers.
  • Fig. 6 shows the assembly principle for modular forms 10.
  • forms 10 are assembled in sequence and next to one another so that the edges 10D of a form can be coupled with the edges 10D of the adjacent forms, that are appropriately shaped according to known shapes.
  • Fig. 7 shows an example of a floor with forms 10, which is similar to the one described in Figures 1-4 above.
  • a traditional electrowelded wire mesh 4, and possible rods for the absorption of negative moments, will be placed on the extrados, above the assembled modular forms 10.
  • the resulting structure is then used as a base for an ordinary concrete cast.
  • the casting is carried out using high resistance concrete, dosed in accordance with project specifications as schematically indicated under number 5 of Fig. 7. Even in this case, the amount of concrete cast should be suitable to saturate all the seats D and guarantee the presence of a specific amount of concrete even above the upper walls 1A and 10A of the forms and to submerge the mesh wires 4.
  • forms 10 are assembled in sequence and side by side in order to create the lightening cavities of the floor (constituted by the cavity inside walls 10A-10B of forms 10) and to define the longitudinal load-bearing crossed ribs formed by the concrete that fills seats D and the related reinforcing elements.
  • seats D form actual load-bearing ribs or beams with light reinforcement.
  • each form 10 can be used to form a lacunar element.
  • the installation of more lacunar elements or forms 10 enables to create a double set of load-bearing ribs in both directions.
  • Lacunar floors, with double set of load-bearing ribs will be delimited, as explained above, on all four sides by beams or resting surfaces suitable to tolerate the loads that are characterised by a non linear trend and by a generally variable trend with triangular configuration.
  • this kind of floor is not characterised by a preferential load-bearing direction and that it is almost entirely made of concrete, the theoretical hypothesis of infinitely rigid orientation formulated in anti-seismic calculations is much more real and alike to the actual status as compared to traditional techniques.
  • crossed ribs are particularly useful for anti-seismic structures, but complex to form with the traditional floor building components and techniques known so far.
  • the invention demonstrates the opposite by showing that crossed ribs are easy to achieve with the forms and methods described in the invention.
  • the techniques described in the invention enable to produce floors in concrete that can be lightened, shaped and equipped with load-bearing reinforced ribs, running along one or both directions of the plane through the use of the forms described.
  • the lower surface of this floor can be left open (in this case, special care should be adopted when preparing the concrete) or covered with all kinds of false ceilings.
  • the upper surface of the floor formed by the layer of concrete that surmounts the extrados of the forms, can accommodate a screed with the minimum thickness (4 cm) required by laws and the desired coating.
  • the only essential materials required to produce the floors described in the invention are the reinforced elements 3 situated inside the seats D, the electrowelded metal wires 4 situated on the extrados and the dosed concrete cast 5, with the resistance indicated in project specifications, required to "submerge” all the forms and the wire 4.
  • edges 1D, 2D and 10D, described above, are preferably equipped with reciprocal coupling devices conceived according to whichever suitable already known design.
  • the forms described in the invention can be satisfactorily made of pure or recycled plastic.
  • the preferred material is generally a polypropylene of a kind resistant to the impacts and the low temperatures that may occur within the building yard.
  • the forms described in the invention can be satisfactory produced by thermal vacuum forming or injection moulding.
  • the moulding draft angle of the item should allow a compact stacking to facilitate the storage of the forms and their removal from the concrete. Shapes, thickness and, if necessary, possible ribs should allow complete treadability.
  • the essential characteristic of the invention lies also in the possibility of re-using the forms to produce several floors, which enables to significantly reduce costs as compared to traditional techniques.
  • the shape of forms 10 can differ from those described above to allow the management of a whole series of aesthetic variants and the production of vaults or lacunar elements with various characteristics and shapes of the upper and side walls 10A and 10B.
  • item number 20 of Fig. 8 shows a form that is very similar to that illustrated in Figures 5-7, and thence constituted by an upper wall 20A, by four side walls 20B and by adequate resting and coupling edges 20D.
  • one or more side walls 20B may have an opening, indicated with number 20E, for the insertion of a special hollow tubular element.
  • this tubular element referred to with number 30, substantially has a truncated conical shape. They also may be made using vacuum forming or injection moulding of plastic materials.
  • Figures 10 and 11 show that the tubular elements 30 are suited to be threaded through the openings 20E of the forms 20, in order to allow them to project from the forms themselves.
  • the assembly of forms 20 is substantially carried out with the same procedures described for Fig. 6.
  • the tubular elements 30 that project from the two walls facing the adjacent forms 20 will be reciprocally coupled.
  • the external ends of elements 30 are equipped with special reciprocal coupling devices constituted, as shown in Fig. 9, by a series of alternated relieves 30A and seats 30B.
  • This scaffolding should be configured in order to provide openings for the insertion from below of the tubular elements 30 into the central cavity of the forms 20 and consequently also into openings 20E.
  • openings 20E For example, to form these opening it is possible to use a structure constituted by non joined panels or by panels already equipped with openings, etc..
  • seats D The interior of seats D is suited to allow the insertion of bars or iron rods 3, whose ends are rested as known on appropriate beams running along the perimeter.
  • tubular elements 30 are coupled to one another and to the extrados, above the assembled modular forms 20, then the electrowelded wire mesh 4 and possible iron rods for the absorption of the moments negative stresses indicated in the project are placed.
  • the forms 20 with special tubular elements 30, enable to define passages inside the load-bearing beams formed by the concrete that fills the seats D, to establish a direct communication with all the hollow volumes of the floor.
  • the coupling devices used for the tubular elements 30 may differ from those shown in 30A and 30B. These temporary coupling devices will generally be suited to guarantee the linking between the elements 30 during the casting phase and the disconnection of these elements after the consolidation of the concrete.
  • pairs of tubular elements 30 it is also possible to use disposable elements that can be easily broken. Such elements should preferably be in expanded polystyrene. These elements can inserted in sequence after the installation of the reinforcing iron rods, to form a bridge between each pair of openings 20E facing two adjacent forms 20, to prevent the cast concrete from leaking from the openings 20E. Despite the projection of the ends of these elements in the interior of the forms 20, these elements do not prevent extraction. Elements are flexible and can be hollow or easy to break in order to allow the subsequent insertion of pipes and other lines.
  • Figures 14 and 15 show a further variant of the invention to easily obtain passages between the cavity created by the forms.
  • Four identical forms 21 are shown, having an upper wall 21A and four side walls each of which may consist in an upper portion 21B and a lower portion 21C; the lower portions 21C are slightly overhanging with regard to the upper portion 21B so that, substantially in the middle of the height and preferably in the middle of the width, each lower portion can have a seat 21E, open on top, whose back surface 21F is made up by the extension down of the upper portion 21B of the corresponding side wall and whose lateral surface 21G extends from the lower to the upper portions respectively 21C and 21B.
  • the extremities of tubular items 31 can be placed, pushing it down, so to form a bridge among the facing seats 21E of each two adjacent forms 21.
  • the seats 21E are so shaped as to receive, with a slight interference, the extremities of the tubular items 31 that, then, remain locked in their position.
  • the tubular items 31 can be simply pieces of economic plastic tubes of the type used to drain rain water, since they are destined to be submersed and lost in the concrete; accordingly, in the figures 14 and 15, the seats 21E have been shown as having a "U" shape. Of course, in this case, the stacking of the forms 21 cannot be completely compact, due to the interference between the vertical sides 21G of the "U" shaped seats 21E of two contiguous superposed forms.
  • the seats 21E can have the shape of saddle without vertical sides 21G so allowing a compact stacking of the forms 21 as for the forms 1, 2, 10 and 20.
  • the form 21 is utilised substantially as described for the preceding forms; trials have shown that the concrete is not so fluid to flow within the cavities of the tubular items 31 that then, remain empty, safe possible crumbs at their extremities, neither said tubular items 31 are pushed away from their position by the fluid concrete pressure. At the end of the operation, after that the concrete has been cured and the forms 21 removed, the passages between adjacent cavities are obtained simply removing possible crumbs.
  • a first one is the rapidity with which the tubular items 31 can be placed at the correct position.
  • a second one is the rapidity with which the passages between the cavities are obtained since it is not necessary to remove tubular elements such as 30 or disposable expanded polystyrene elements.
  • a third one is the possibility of utilising the same forms both for obtaining roofs with lacunar ceiling at the intrados, since said forms have no holes, and for roofs containing ducts and hidden at the intrados by false ceiling; in fact the lower portions 21C of the side walls and the corresponding seats 21E, although necessary for technical reasons, may be shaped so to have an aesthetic validity.
  • connection means and elements explained to obtain passages between adjacent cavities i. e. the elements 20E and 30 or the disposable expanded polystyrene elements so as the elements 21E and 31
  • the elements 20E and 30 or the disposable expanded polystyrene elements so as the elements 21E and 31 can be used indifferently with the forms 1 and 2.
  • the upper wall 21A of the forms 21 show also that it could be provided with steps 21H and ribs 21I. While the steps 21H have essentially an aesthetic function, the ribs 21I have mostly a stiffening function, to improve the treadability; of course, both steps 21H and ribs 21I can be used with other forms according to the invention. As an example, a form made of polypropylene, 60 x 60 cm wide, 6 mm thick and having ribs 21I 15 mm height has proved to be enough treadable.
  • Figure 14 shows, finally, some locking items 40 placed at the junctions of four vertexes of four adjacent forms 21; not all the locking items 40 are shown in the figure neither it is necessary to place them at all the junctions.
  • Said locking items 40 that can be used with whichever form according to the invention, can be pinned to the wooden bearing scaffolding by means of a nail and can be useful to maintain in their position said forms while pouring the concrete; the locking items 40 are later removed and recovered after having extracted the forms by the cured concrete. Since, in case of a lacunar or vault ceiling, the impression of the locking items 40 on the ceiling remain visible, it can be useful to shape them in a regular form, such as a flat disc, as shown in figure 14, or a rosette, as shown in figure 16.
  • stiffening ribs 21I or proper thickness of the forms it is possible to simply place pieces of a tube of the proper eight between the scaffolding and the upper walls of the forms, in the guise of a strut that will be removed and recovered after having dismounted the scaffolding.
  • the perimeter of the forms according to the invention is not necessarily rectangular or square; for instant, the perimeter could be a regular quadrilateral with no rectangular corners or a triangle.
  • the only condition to be assured, according to the invention is that continuous and rectilinear seats D, destined to contain the reinforcing elements 3, must be created between almost two perimetral load-bearing beams while the side walls 1B, 2B, 10B, 20B, 21B and 21C may have whichever shape provided that they assure the technical requirements requested by the invention.
  • all the forms according to the invention may be used to build up horizontal supporting structures consisting in a grid of crossed reinforced concrete ribs or beams with openings within the ribs to be left free or later covered with other materials so that, for instance, ceiling windows or lanterns can be obtained; according to this version, possible iron rods to absorb moments negative stresses will be positioned on the upper part of the seats D instead than over the upper walls 1A, 2A, 10A, 20A or 21A.
