Definitions

  • the present invention finds application in the field of building materials and building constructions and has particularly for object an external counter-wall structure for thermal-acoustic insulation of buildings.
  • the coating of the external walls of buildings by means of counter-walls and thermally and/or acoustically insulating coats generally involves the application to the external wall of special panels applied directly to the wall or spaced, in the case of so-called ventilated walls, in a manner to form an interspace.
  • dry-laid coatings involve the application of different layers having different functions, such as for example of thermal and/or acoustic insulation or simple aesthetic function.
  • the insulating materials currently in use are typically polystyrene, rockwool and similar materials, as they have a relatively low cost and ease of application.
  • polystyrene, rockwool and similar materials as they have a relatively low cost and ease of application.
  • particular high-energy-efficient heat-reflecting materials with reduced thicknesses compared to known solutions are increasingly used.
  • Such materials are formed by a plurality of layers of different materials, such as pure aluminum, aluminized films, wadding and expanded polyethylene sheets.
  • FR2480834 discloses a coating structure for walls of buildings which comprises most of the features contained in the preamble of claim 1 of the present invention.
  • this coating structure comprises a coating made up of a single layer of glass wool, so there is no problem in drilling this material.
  • the nature of the glass wool coating makes it easy to compress, so that any lack of homogeneity in its thickness can be easily recovered by correctly positioning the supporting frame.
  • US2009308001 discloses a covering structure with a substrate that includes a thermal insulation material comprising at least two materials selecting from a thermal energy reflecting material, a homogeneous foam material, a heterogeneous foam material, a skin material, a skeleton structured material, an electromagnetic wave shielding material.
  • the object of the present invention is to overcome the aforementioned drawbacks by providing an external counter-wall structure for thermal-acoustic insulation of buildings which has characteristics of high efficiency and relative cost-effectiveness.
  • a particular object is to provide an external counter-wall structure for thermal-acoustic insulation of buildings that allows the use of the latest generation of thermal reflective materials in a particularly efficient manner and conferring high properties of thermo-acoustic insulation to the structure.
  • an external counter-wall structure suitable for covering the external wall of a building to realize its thermal-acoustic insulation or to increase its thermal and / or acoustic insulation characteristics is illustrated.
  • the structure generally designated by 1, essentially comprises a multilayer coating 2 suitable for covering the external wall P of a building, anchoring means 3 of the coating 2 to the external wall P, spacer means 4 adapted to be placed between the coating 2 and the external wall P to keep the coating 2 spaced from the latter and define a first static interspace 5, as required by the regulations.
  • the multilayer coating 2 will comprise a plurality of layers of different materials, with the outer layers which will be made of reflecting materials, such as aluminum or its alloys or materials based on aluminum and the like, possibly coupled to a reinforcement net.
  • the coating 2 will be a multilayer available on the market and also having 19 layers in different materials, such as pure aluminum, aluminized sheets, wadding and expanded polyethylene sheets.
  • the structure 1 then comprises a supporting frame 6 adapted to support an outer covering 7 and which is placed on the opposite side of the multilayer coating 2 with respect to the spacer means 4.
  • the structure 1 is composed of fiber-cement padding panels fixed on a supporting frame 6 formed by a double support frame made of zinc-magnesium steel, by applying the 19-layer thermo-reflecting insulating material in the interspace.
  • the insulating coating 2 has two outer faces of self extinguishing protected pure aluminum coupled to a reinforcing net; the seventeen inner layers consist of seven further reflecting films, of which four layers of wadding and six layers of expanded Pe film.
  • the material is sewn on the edges and is provided with a sealing system of the layers with plastic threads every 40 cm that allows avoiding excessive opening during cutting, ensuring also uniform thickness and consequent reduction of thermal bridges.
  • the anchoring means 3 has a plug 8 adapted to be fixed in the external wall P of the building and a pin 9 which can be inserted in the plug 8 to protrude from the external wall P with predetermined length that can be chosen according to the features and dimensions of the multilayer coating 2, as well as to the supporting frame 6.
  • each pin 9 will be constituted by a threaded bar having a pointed free end designed to provide a corresponding hole in the multilayer coating 2 upon application by pressure of the latter on the anchoring means 3 , thus solving the problem of anchorage of this type of multilayer coatings which cannot be drilled by a drill or similar means.
  • the spacer means 4 comprise a plurality of spacer elements 10, for example sleeves having a thickness of 24 mm, inserted on respective pins 9, with the interposition of a first washer 11, arranged between the wall of the building P and the spacer element 10, and a second washer 12, arranged between the spacer element 10 and the inner side of the coating 2.
  • the supporting frame 6 is anchored to the coating 2 always by means of the same anchoring means 3.
  • the spacer means 4 also comprise a plurality of wooden cross members 13, preferably mineralized wood, arranged to be located between the external wall P of the building and the inner side of the coating 2 in a substantially horizontal position and vertically offset, at the zones free from fasteners 3.
  • the spacer means 4 comprise a plurality of adjustment nuts 14 adapted to be inserted into the holes made by the pins 9 inside the coating 2 following the application of the latter on the anchoring means 3.
  • the adjusting nuts 14 can be screwed onto the threaded bars of the corresponding pins 9 with adjustable depth to locally vary the distance of the multilayer coating 2 from the wall P.
  • the supporting frame 6 comprises a plurality of vertical uprights 15, for example made of galvanized aluminum, anchored each to the anchoring means 3 with the interposition of pairs of bolts 16 placed on opposite sides of the respective vertical uprights 15 and screwed onto the threaded bar of the respective pin 9 to adjust the inclination of the vertical uprights 15, so as to recover any possible inclination of the wall P of the building.
  • the supporting frame 6 also comprises a plurality of horizontal uprights 17, for example made of galvanized aluminum, which can be anchored to vertical uprights 15 and suitable for supporting the outer covering 7, for example a fiber cement panel, and defining a second interspace 18.
  • the vertical uprights 15 and the horizontal uprights 17 comprise means for the mutual snap coupling.
  • the vertical uprights 15 comprise a plurality of C-shapcd recesses 19 provided with retaining teeth 20 adapted to interact with enlarged longitudinal edges 21 of the horizontal uprights 17 and block them by interference following their snap coupling.
  • retaining teeth 20 adapted to interact with enlarged longitudinal edges 21 of the horizontal uprights 17 and block them by interference following their snap coupling.
  • the wooden cross members 13 will be positioned, which may have, for example, a 30x20 mm section, with a center distance of 400 mm, as a spacer between the support wall and the thermal reflective insulation coating 2, in order to create the first interspace 5 of 20 mm.
  • the coating 2 is laid by resting it on the tips of the jointing pins 9, applying a manual pressure until the head of the threaded pin 9 comes out for drilling. Subsequently, the second washer 12 is positioned, for anchoring then the supporting frame 6, stopping the vertical uprights 15 and the horizontal uprights 17 with additional washers and with the bolts 16.
  • the use of the multilayer coating will make it possible to achieve considerable advantages from a point of view of energy performance, minimum dimensions, the adjustability for leveling the façade planes, for elasticity with respect to thermal and mechanical deformations, for inexpensiveness compared to other types of insulating dry walls, due to the simplicity and speed of installation.
  • the structure 1 is composed of non-load-bearing but self-supporting building elements and therefore its installation does not directly contribute to the stability of the existing masonry on which it is laid but instead contributes to their durability over time providing better protection from meteorological effects, protecting the building itself from external atmospheric agents.
  • the coating 2 is also made of imputrescible materials, which do not absorb moisture and therefore do not lose their properties over the years, guaranteeing very high thermal performances as they reflect the radiant energy in very high percentage, substantially differentiating from the other insulators present in nature which, moreover, to exert their insulating function depend directly on the thickness.
