Definitions

  • the present patent concerns products for the building construction sector, and in particular it concerns a new insulating and reinforced modular covering for walls in general and a process for making said covering.
  • a covering for walls of buildings or surfaces in general known from GB2452302 comprises:
  • the lattice may be applied directly to the existing plaster and insulating layer, once the resistance of the fixing means has been verified.
  • Walls provided with an overcladding layer are known, said walls typically being the external perimeter walls of a building.
  • Said overcladding layers comprise at least one layer of insulating material applied to the external surface of the perimeter wall with bonding agents and mechanical fixing elements, a first, cement-based, a few millimetres thick levelling layer being successively applied to said layer of insulating material.
  • a fibreglass plaster mesh is buried in said first levelling layer and then a second levelling layer, at least 3 mm thick, is applied on it. Once the whole has dried up, a finishing layer is applied onto the overcladding.
  • the insulating layer is generally constituted by panels made of an insulating material, for example synthetic foam material, or mineral wool, or organic material, etc.
  • the covering layer applied to said panel is usually very thin, just a few millimetres, and therefore there is the problem of guaranteeing the adhesion of the covering to the insulating layer and of the latter to the wall, in addition to guaranteeing the stability of the system over time.
  • An overcladding system is also known, which is specifically used for mineral wools, and which in order to make up for the low resistance of the latter to compression requires the application of a metallic plaster mesh to be applied to the entire wall.
  • This plaster mesh needs many special supports intended to keep it well stretched and spaced from the insulating panels previously fixed to the wall. Furthermore, special fixing elements are needed to make the plaster mesh and its plaster layer integral with the underlying wall.
  • Document DE 32 06 163 concerns a construction element intended to be used as a support for plaster, in particular in the cases where there is the need to create a rather thick and uniform plaster layer on large surfaces.
  • the construction element illustrated in the document mentioned above is a plate-like element with a uniform shape, with portions projecting crosswise from the upper and from the lower side of the construction element itself.
  • Said portions are in the shape of a frustum of pyramid with four sides or of a frustum of pyramid with eight sides or of a truncated cone.
  • Said portions have closed sides and open opposite bases.
  • the construction element obtained in this way thus comprises a plurality of openings extending through the element itself, in which the plaster to be applied is introduced.
  • the portions projecting from the upper side are open, while the portions projecting from the lower side are closed.
  • the construction element cannot be considered a net, but rather a plate-like formwork with projections and recesses, of which only the projections towards the upper side are provided with openings for the introduction of plaster.
  • the document mentioned above shows an example of use of the construction element applied to a bearing wall, wherein the closed portions face towards the wall, while the open portions allow the introduction of plaster, which reaches and adheres to the bearing wall.
  • the construction elements serve as a reinforcing structure for the insulating plaster and at the same time as a gauge suited to measure the thickness of the insulating plaster layer.
  • a drawback posed by the method described above lies in that practically the plaster is in contact with the bearing wall only on a part of the total surface of the construction element, and in particular only at the level of the open portions, while in the area where the closed bases of the closed portions rest there is no contact between plaster and wall.
  • the partial contact between the plaster layer and the wall does not guarantee at all the effective adhesion of the covering to the wall.
  • the sides of the projecting portions are solid and therefore the plaster layer that is obtained is substantially constituted by a plurality of plaster sectors included between the sides of the projecting portions, said sectors being completely separated from one another.
  • the sides of the projecting portions are smooth and inclined in the plaster shake-out direction, which therefore will tend to slide downwards as no gripping effect is possible.
  • These projecting portions are plaster containers and are separated from one another by their own sides. The plaster layer obtained in this way is thus divided into many small cells and for this reason it cannot be considered a reinforced monolithic structure, so that a second reinforcing metallic net needs to be applied.
  • the plaster layer obtained in this way is thus discontinuous and furthermore the plaster adheres only to the inclined surfaces of the projecting portions and only to a part of the bearing wall. This leads to the inevitable formation of cracks and to the concrete risk of the layer coming off.
  • the lattices used in the new covering work as a real reinforcing structure for very thick plaster layers, as each lattice is completely buried in the cement plaster, exerting its action horizontally and vertically within the plaster layer.
  • the lattice described in the present patent application in fact, in its preferred embodiment is constituted by a plurality of portions arranged in such a way as to substantially form a reticulated structure with three-dimensional meshes open in all directions, parallel and transverse with respect to the plane of the lattice itself, and this allows the cement plaster to penetrate the lattice in all directions and thus to incorporate the lattice completely.
  • the lattice thus forms a real reinforcing structure for the layer of cement plaster obtained by proceeding as described, with no need for the addition of further reinforcing bars.
  • the layer of cement plaster obtained is characterized in that it is continuous and also completely in contact with the bearing wall, over the entire surface of the lattice.
  • the lattice is coupled with an insulating panel, creating a sort of kit to be installed with the aid of suitable fixing means.
  • construction element described above is configured in such a way that it needs to be partially overlapping other identical construction elements in order to join them.
  • said projecting portions are arranged and shaped in such a way that they need to overlap those present on a corresponding part of another identical construction element.
  • the partial overlapping of two construction elements implies that the construction element cannot be coupled individually with an insulating panel.
  • the installation process is very complicated and articulated, as the construction elements can be constrained to the insulating layer only after being joined to one another so as to form a continuous layer.
  • the construction element can serve as a container intended to receive loose insulating materials and to prevent such materials from moving.
  • This element is not a reinforcing net, but rather a counter formwork for plaster, so that the latter takes the shape of the underlying element, in the form of cells or niches.
  • the element constitutes a separator between the upper layer and the lower layer of plaster, provided that the latter can flow through the holes of the projections and fill their cavity completely, which is impossible.
  • the element proposed in the above mentioned document is a continuous element and is constituted by a series of projections in various truncated cone shapes that are specular to the separation plane, so that they can be partially or completely overlapping on their entire surface, differently from the element proposed herein, which does not overlap another element due to its different configuration.
  • FIGs 23, 24, 25 of the above mentioned document also show fixing means suited to fix the construction element to the wall and resting on the lower part of the construction element, so that said fixing means do not cooperate with the plaster, differently from the invention proposed herein, in which the fixing washer works within the cement plaster layer, which means that also the structural design of the two systems is necessarily different.
  • the two construction elements are structurally different from each other, and require different application methods that adopt different solutions to solve the same problems.
  • Document EP 2871301 concerns a process and supporting elements for the application of insulating means for the building construction sector, such as heat insulating panels, plaster or other elements for the renovation or improvement of existing overcladding layers of buildings.
  • the technical problem addressed by the document just mentioned above concerns the application of a new layer of insulating panels or plaster to a wall with pre-existing plaster or pre-existing insulating panels that need refurbishing or where it is necessary to repair damaged finishing surfaces.
  • the supporting element described in the document mentioned above comprises a substantially parallelepiped and elongated element, delimited by longitudinal crosspieces and front crosspieces arranged in an arrow-shaped layout, wherein the longitudinal crosspieces are generally much longer than the front crosspieces.
  • the front crosspieces arranged in an arrow-shaped layout make it possible to join said supporting elements orthogonally to one another, thus forming square or U-shaped self-bearing structures suited to be constrained to the bottom.
  • the structure obtained in this way is a frame which is empty inside and adheres to the support, to which it is possible to apply glue for construction elements or plaster.
  • the structure obtained by joining together said supporting elements therefore, is not a continuous surface, but a series of frames that are empty inside, with which it is not possible to obtain a continuous reinforced plaster layer.
  • discontinuous elements are fixed individually to the wall to be renovated, forming frames that are empty inside; they are not and cannot be applied to the insulating panel before the laying procedure, therefore their use and their applications are limited.
  • the heat insulating layer if any, is thus applied onto said supporting elements, not in direct contact with the wall to be renovated. Furthermore, said insulating panels or other construction elements are constrained to the supporting elements by means of bonding agents, while there is no further fixing means between the insulating panels and the wall.
  • Document WO 2008/018081 concerns a method and a corresponding system for applying plaster in such a way that it remains detached from the wall, and can be applied in particular to walls having deposits of salt crystals on their surface, as it normally happens in marine environments.
  • the system comprises a first intermediate element suited to be placed on the bearing surface and provided with a plurality of empty spaces facing towards the wall itself, in which the salt crystals that form on the wall can be collected.
  • the opposite part of the intermediate element instead, is provided with a smooth surface to which the plaster layer can be applied, and wherein said intermediate element has also the function of preventing any communication and penetration of material between the side to be rendered and the side facing towards the bearing wall.
  • a panel with polycarbonate through cells closed laterally in a honeycomb configuration is rested against the bearing wall in order to define empty spaces suited to collect the salt crystals, while a separation cloth is laid on the opposite side to prevent the passage of plaster.
  • the intermediate element is made of a foam material having, on its surface facing towards the bearing wall, a series of recesses suited to form empty spaces where the salt crystals are collected, while the opposite surface is smooth and continuous, so as to prevent the passage of plaster.
  • the plaster mesh used does not add anything to the known technique, according to which meshes are used to guarantee the adhesion of thin layers of plaster. Furthermore, no part of the description addresses the problem of how layers of plaster with increased thickness can be obtained.
  • the mesh used is a normal honeycomb mesh, with closed sides defining sectors which are separate from one another.
  • the new covering that is the subject of the present patent application, instead, in its preferred embodiment uses a sort of three-dimensional net, specifically provided with openings in all directions, in such a way that the cement plaster that incorporates the net completely forms a continuous layer, meaning without any internal partition creating discontinuity.
  • a further aspect that differentiates the new covering from the system described in the document mentioned above lies in that it is necessary to face and solve technical problems that are completely different from and independent of one another.
  • the invention instead, has the object to provide an overcladding layer for buildings, comprising a very thick plaster layer made mechanically on a special reinforcing plaster mesh which is applied directly onto the insulating panels and which can be used for all buildings and in any context.
  • the object of the new covering is to speed up the laying procedure and make it safer, improving the insulating, mechanical, acoustic, and fire resistance performance.
  • Document DE 20 2010 007 659 concerns an insulating panel provided with an insulating layer for heat insulation of the external walls of buildings, wherein said insulating layer is constituted by a panel made of an insulating material and by a bidimensional grid fixed to the external side of said insulating layer.
  • the insulating layers were fixed by means of common screw anchors and successively a plastic mesh was laid for the layer of resin plaster.
  • the technical problem that the above mentioned document intends to solve is to make it possible to lay a uniform plaster layer, as when the known technique was used the insulating layer could present lowered portions at the level of the screw anchors which were driven too deep into the wall, and projections at the level of screw anchors driven less deep into the wall.
  • the panel illustrated in the document mentioned above thus solves this technical problem through the application of a net directly in contact with and at the level of the external side of the insulating panel, having the function of offering well defined fixing points, in such a way that the surface on which plaster will be successively applied is uniformly plane.
  • the plaster mesh does not work and cannot work as an element suited to reinforce the plaster layer, as it cannot be buried into it.
  • the plaster mesh is constituted by a plurality of supporting rings joined to one another through crosspieces.
  • the rings serve to define the points where the screw anchors are driven, through the use of cylindrical elements that are introduced in said rings and in the insulating panel.
  • the screw anchors are inserted in said cylindrical elements and their head rests against the lower or inner edges of the cylindrical elements.
  • the innovative aspect is represented by the rings, which have the purpose of moving the fixing point away from the plaster mesh, so that "on one side, during the fixing step the structure of the insulating panel is subject to a reduced risk of deformation, and on the other side, thanks to the distance of the steps from the surface of the grid, there is no risk of these remaining visible as projecting spots after the application of plaster.”
  • the plaster mesh is glued to the insulating layer "not only in the area of the supporting rings, but also in the area of the crosspieces located on the insulating layer itself: in this way ample support is obtained, so that the grid adheres to the insulating layer also in the presence of thin crosspieces.”
  • the plaster mesh does not have the function of reinforcing a cement plaster layer, but serves as a counteracting element for the screw anchors of the insulating panel.
  • the fixing screws are not buried in the plaster layer, and do not contribute to the stability of the same.
  • each crosspiece in a possible embodiment of the plaster mesh the height of the crosspieces can extend to the upper corners of the rings. In this way, however, each crosspiece substantially becomes a closed side that projects from the surface of the insulating panel up to the height of the rings.
  • the plaster layer that is obtained in this case is thus discontinuous, being formed by a series of sectors which are separated from one another by said crosspieces and by the sides of the rings.
  • a first difference between the covering described in the document mentioned above and the new covering that is the subject of the present invention lies in that the lattice of the new covering is constrained to the insulating panel only in certain points, at the level of the lowered portions, while the plane mesh remains completely spaced from the insulating panel and thus can be completely buried in the cement plaster.
  • the cement plaster thus adheres to the entire insulating panel and completely encloses the mesh, which thus constitutes a real reinforcing and bearing element for the layer of cement plaster obtained.
  • the layer of cement plaster which can be obtained in this way is at least thicker than the overall thickness of the lattice, meaning even 2-4 cm thicker.
  • a second important difference between the covering described in the document mentioned above and the new covering that is the subject of the present invention lies in that the heads of the screw anchors are always maintained above the mesh, and not under the insulating layer, as explained in the mentioned document.
  • the heads must be buried in the cement plaster layer, in order to guarantee the structural stability of the entire system constituted by wall, insulating panel, lattice and cement plaster layer.
  • Document US 1808976 concerns an insulating panel coated with plaster, comprising a panel made of an insulating material, a waterproof covering sheet applied to one side of said insulating panel, an expanded metal sheet applied to said waterproof covering sheet and intended to face towards the outside so that a plaster layer can be applied to it.
  • These three layers meaning the insulating panel, the waterproofing sheet and the expanded metal sheet, are constrained to one another by means of clips.
  • the expanded metal sheet can be deformed, thus defining transverse ribs in contact with the waterproofing sheet, and at the level of which the fixing clips are applied, while the remaining part of the expanded metal sheet is spaced from the waterproofing sheet. In this way the plaster gets under the expanded metal sheet and incorporates it completely.
  • plaster panels are obtained which are insulating and modular at the same time and can be applied to the wall to be insulated, wherein the waterproof sheet has the function of protecting the insulating layer, while the expanded metal sheet is protected against humidity, being completely buried in the plaster layer.
  • the ribs in the net are not intended to increase the thickness of the plaster layer that is going to be obtained, either, but only to allow the plaster to reach the back of the mesh in the case of insulating layers that are not yielding.
  • the fixing means provided are simple clips that constrain the three layers to one another, but said clips are not expected to contribute to the stability of the plaster layer which will be obtained, as they remain well constrained at the level of the waterproof sheet, without allowing plaster to get under them.
  • the panel that is the subject of the above mentioned document has been clearly designed for use in interiors. This can be easily understood both from the type of material used, meaning plaster and any further plaster finishing layer, and from the presence of the waterproofing layer that serves as a vapour barrier and that, as already known, is always positioned on the warm side of a wall, meaning towards the inside.
  • the panel structured in this way cannot be used to make overcladding systems with a reinforced cement plaster layer, substantially for two reasons.
  • First of all it lacks a specially shaped mesh suited to hold a thick layer of cement plaster and to serve as a reinforcing structure for the layer itself.
  • the second reason is the absence of fixing means capable of cooperating with the cement plaster layer in order to fix the layer itself to the wall to be covered.
  • the above mentioned document in fact, does not define the procedures for fixing the layer to the wall but, considering the time when the document was written and the type of application, it can be inferred that such fixing operation is carried out through adhesion obtained using bonding agents or plaster.
  • the main object of the present invention is to provide a system that facilitates and quickens the application of layers of cement plaster and guarantees the stable adhesion of cement plaster to the wall or to any underlying insulating panel.
  • the new covering in fact, makes it possible to obtain a layer of cement plaster characterized by a heavier weight compared to the resin-based plaster or simple plaster used in the known techniques up to now.
  • the acoustic insulation of the wall is considerably improved thanks to the stratigraphy of the mass spring mass system.
  • the thermal inertia of the wall is improved, as well as the sun heat insulation resulting from the larger mass applied externally.
  • the levelling operation is performed through the temporary application of linear bars, distributed so that they are parallel to one another and constrained in a removable manner to said lattices, for example through coupling means.
  • Said bars serve as a guide for laying the levelling layer by means of suitable tools.
  • said bars are removed and the chases are filled.
  • the process finally includes the finishing of the covering, which is conveniently carried out once the cement plaster has dried completely, for example after 28 days.
  • Said finishing step may comprise the following operations:
  • the new covering obtained by proceeding as described above thus comprises a very thick plaster layer, wherein the minimum thickness of the cement plaster layer is defined by the distance between said counteracting plane defined by said lattices and said insulating layer.
  • cement plaster is thus carried out mechanically on a special reticulated reinforcing structure for cement plaster applied directly to the insulating panels and suited to be used in all types of building and in any context.
  • the heads of the fixing means rest against specially shaped portions of the lattice, in such a way that they are constantly maintained above the plane where the lattice lies.
  • the heads of the fixing means are buried in the cement plaster layer, for the purpose of ensuring the structural stability of the entire system constituted by wall, insulating panel, lattice and cement plaster layer.
  • Said reinforcing structure or lattice is modular, bidimensional or three-dimensional, and serves as a cement plaster mesh suited to be directly or indirectly constrained to a wall and to be completely buried in the cement plaster through the superimposition of the meshes on two adjacent sides of each panel.
  • Said lattice has a substantially rigid structure, though being flexible in one or preferably both of the orthogonal directions.
  • Said lattice or grid-shaped modular element can be made of any material, metallic or non-metallic.
  • said lattice is made of a metallic material and is obtained through a joining or welding or deformation process or through any of the processes used to make metal lattices.
  • said lattice is mainly or exclusively made of a plastic material, for example obtained through a thermoforming or injection process, and is preferably in a single piece.
  • Said cement plaster may conveniently have more advanced technical characteristics compared to common plasters, for example it may be already coloured as a whole so that it would be possible to avoid the final painting of the overcladding layer, or be a special mortar with heat insulation or self-cleaning characteristics, or be capable of absorbing polluting substances present in the air, or be another type of plaster.
  • the lattice may come in various shapes, but however it must be suitable for holding and retaining the cement plaster with its meshes, independently of how they are made.
  • Said lattice comprises also said one or more reinforced portions, substantially coplanar with or in any case parallel to the plane where the lattice lies, and ready for the insertion of means or screws for fixing said lattice to said wall.
  • Said fixing means comprise, for example, one or more screw anchors or screws or means suited to be inserted in apposite seats or through holes obtained in said reinforced portions of said lattice and suited to constrain said lattice to said wall.
  • said fixing means are inserted in said seats or through holes in such a way that the head of said fixing means is raised with respect to the surface resting on the insulating panel and coplanar with the net, so that said heads will be completely or at least partially incorporated in said layer of cement plaster.
  • Each one of said lattices preferably comprises also overlapping parts that join adjacent lattices, described and claimed here below and having the purpose of guaranteeing the continuity of the meshes along the wall, thus avoiding possible cracks in the plaster in the areas where the edges of the panels are adjacent to each other.
  • said overlapping parts comprise at least one grid strip constrained to said lattice in proximity to one or more of its edges, preferably adjacent; said strips are arranged parallel to the edge of the panel and partially project from the latter, in such a way that they can overlap the edges of adjacent lattices. Said strips have the function of holding the cement plaster, thus guaranteeing the continuity of the reinforcing structure in the cement plaster layer also along the adjacent edges of adjacent lattices of each panel.
  • Said lattice may also comprise one or more reference marks located on the side of said lattice not facing the wall, that is, facing towards the outside.
  • Said reference marks which can be in the shape of projections or elements in general, can be conveniently used as reference indicators for the correct application of the cement plaster.
  • the new reinforcing structure comprises said at least one rigid lattice shaped as a net with open meshes suited to reinforce and contain a very thick layer of cement plaster, and a plurality of projections or protrusions in general suited to space the plane of said lattice, meaning the surface near the levelling layer, from the underlying insulating layer, in order to define in this way a hollow space with solid and empty spaces, suited to be filled with cement plaster, wherein said cement plaster adheres to the meshes of the lattice.
  • said lattice is substantially like a three-dimensional net with openings in all directions, so that the cement plaster which incorporates the net completely forms a continuous layer, meaning a layer without any internal partition creating discontinuities.
  • said projections or protrusions are integral with or in any case joined to said lattice, being raised from the surface of said lattice intended to be facing towards said insulating panel or towards the wall, meaning towards the inside. Therefore, said lattice is in contact with the insulating panel only in certain points, at the level of the edge of said projections.
  • the lattice is open in all directions, parallel and transverse to the plane of the lattice itself, and this allows the cement plaster to penetrate the lattice in all directions and thus to incorporate it completely.
  • the lattice thus forms a real reinforcing structure for the layer of cement plaster obtained, wherein said reinforcing structure is developed with vertical and horizontal components, and therefore with no need for the addition of further reinforcing bars.
  • the cement plaster layer obtained is characterized in that it is provided with a continuous reinforcing structure and furthermore adheres completely to the insulating panel, over the entire surface of the lattice.
  • the latter therefore, constitutes a real reinforcing and bearing structure for the cement plaster layer obtained.
  • the cement plaster layer that can be obtained in this way is at least thicker than the lattice as a whole, meaning even 2-4 cm.
  • the preferred configuration of these projections is preferably a closed geometrical shape, for example a cylindrical shape. Said projections are distributed on the lattice at a preset distance from one another, also in order to allow the positioning of pipes for cooling or heating the wall, in a possible solution.
  • Radiant pipes suitable for the circulation of water or another heat exchange fluid in general and for connection to geothermal or accumulation systems, are constrained to the lattice itself by means of special undercut protrusions obtained in the upper part of said projections.
  • said lattice is positioned on the insulating panel with the projections arranged towards the outside, meaning towards the side that is going to be plastered.
  • said projections will be facing towards the insulating panel and in direct/indirect contact with it, wherein at the level of said projections said lattice is joined to said insulating panel in certain points, while the reticulated portion will be facing towards the cement plaster.
  • said reticulated reinforcing structure or lattice is configured with solid and empty spaces included between said two planes, in such a way as to guarantee the continuity of the cement plaster layer and the adhesion of said cement plaster to the panel on which said lattice rests.
  • Said lattice in this solution, can be in different shapes and sizes, but in any case will have to meet the following requirements, which are the object of the present invention, in order to fulfil its functions:
  • the new covering furthermore comprises said mechanical fixing means suited to fix said modular elements to the wall to be covered, in order to guarantee the safety and the stability of the plastered wall.
  • Said fixing means preferably comprise a special load distribution washer, coplanar with the external portion of the lattice, which is maintained integrally constrained to the insulating panel and to the wall, forming a stable unit, in which said washers of the fixing means, being completely buried in the external layer of cement plaster, guarantee the firmness and safety of the wall.
  • said projections or protrusions in general can be made separately, for example in a plastic material, and then applied to the lattice in any way.
  • said projections and protrusions can also be made of a metallic material, be generically formed together with said lattice or applied to it in any way.
  • said projections or protrusions can be integral with said insulating panels, joined to them or formed together with them, for example and in particular in the case where said insulating panels are made through a moulding process or another technology.
  • Said projections can have various shapes and different orientations: they can be pin-shaped or in any case linear, substantially orthogonal, in the shape of a variously oriented blade or partition, with a cylindrical or prismatic surface or a closed geometric shape in general, complete or partial, with or without an enlarged base suited to rest on the underlying insulating panel, with or without further lower nails or protrusions suited to be driven in said insulating panel, with or without transverse through holes for the passage of cement plaster.
  • said modular element is a grid-shaped element substantially constituted by at least one net with three-dimensional meshes.
  • Said insulating layer is in turn constituted by a plurality of modular insulating panels.
  • the insulating panel can be of different types: with organic origin, such as EPS, XPS, polyurethane, or mineral, such as glass or rock wool, or natural, such as wood fibres, cork, natural fibres obtained from waste deriving from the processing of rice, maize, hemp, wool, etc.
  • organic origin such as EPS, XPS, polyurethane, or mineral, such as glass or rock wool
  • natural such as wood fibres, cork, natural fibres obtained from waste deriving from the processing of rice, maize, hemp, wool, etc.
  • each one of said modular lattices is coupled with at least one of said modular insulating panels.
  • said insulating panel may be shaped in such a way as to maximize adhesion to the cement plaster layer.
  • the surface of said insulating panel facing towards said lattice and intended to come into contact with the cement plaster may be provided with a plurality of recesses, preferably in the shape of grooves parallel to one another, suitable for the introduction of cement plaster, in order to improve the grip of the cement plaster itself onto the insulating panels, so that the screw anchors are not loaded with the weight of the cement plaster.
  • Said insulating panels will be preferably installed on the wall in such a way that said grooves are arranged in horizontal direction.
