Wall with transparent insulated sheet

Abstract

 A wall (60) with transparent material sheet (50) is described, which provides for a multilayer sheet (1, 1b, 70) associated with said transparent material sheet (50) by means of a joint (51) to form a closed chamber (52) between them (1, 1b, 70, 50). Said multilayer sheet (1, 1b, 70) comprises at least one transparent material sheet (4) and at least one opaque material sheet (2, 3) with at least one through hole (20).

Description

[0001] The present invention relates to a wall with a transparent insulated sheet.

[0002] Walls made of transparent glass are known, for example in skyscrapers, where in order to increase the insulation while preserving the passage of light, a second transparent inner glass is provided, which is joined to the outer glass by the interposition of a chamber containing vacuum or inert gas.

[0003] Disadvantageously, insulation is very limited and the amount of light passing is too high, especially in warm places.

[0004] There are multilayer sheets for building coatings, e.g. as described in patent document DE3921779A1 where the multilayer sheet comprises two layers of ceramic material and two or more inner layers of glass fiber having the function of thermal insulating material. Said multilayer sheets are totally opaque.

[0005] There are patent documents such as for example US4640850, which describes a multilayer sheet for building coatings comprising a stone material sheet protected by a layer made of transparent glass so as to make the stone material glossier. Disadvantageously, light cannot pass through said multilayer sheets.

[0006] In order for the light to pass through the stone, the patent document EP1555119A1 describes a multilayer sheet for building coatings comprising at least one thin layer of marble protected by at least one layer of transparent glass. Said marble sheet is difficult to be manufactured and disadvantageously fragile. Furthermore, said thin marble sheet allows only a part of the light to pass and cannot be seen through.

[0007] In order for the light to pass through a wall without filters, the wall needs to be bored, thus reducing its insulation.

[0008] Sheets of porcelain ceramic material are also known, which have acoustically and thermally insulating properties, but do not allow any passage of light.

[0009] It is an object of the present invention to provide a wall comprising a transparent material sheet which needs to be associated with a robust multilayer sheet with excellent thermal and acoustic insulation properties, which allows light to penetrate and allows it to be seen through.

[0010] In accordance with the invention such an object is achieved by a wall with a transparent material sheet, characterized in that it provides a multilayer sheet associated with said transparent material sheet by means of a joint to form a closed chamber therebetween, said multilayer sheet comprising at least one transparent material sheet and at least one opaque material sheet with at least one through hole.

[0011] Preferably, the transparent material is glass.

[0012] These and other features of the present invention will become more apparent from the following detailed description of practical embodiments thereof, shown by way of non-limiting examples with reference to the accompanying drawings, in which:

Figure 1 shows a front perspective view of a multilayer sheet;

Figure 2 shows a rear view of the multilayer sheet;

Figure 3 shows a sectional view according to the line III-III in Figure 2;

Figure 4 shows a front perspective view of an alternative multilayer sheet;

Figure 5 shows a rear view of the alternative multilayer sheet;

Figure 6 shows a sectional view according to the line VI-VI in Figure 5;

Figure 7 shows a plan view of a wall according to the present invention;

Figure 8 shows a sectional view according to the line VIII-VIII in Figure 7;

Figure 9 shows a sectional view similar to that in Figure 8, of an alternative wall according to the present invention.

Figures 1-3 show by way of example a multilayer sheet 1 comprising a transparent material sheet 4 enclosed between a sheet 2 of opaque material, more precisely of porcelain ceramic material, and another sheet 3 of opaque material, more precisely of porcelain ceramic material.

[0013] Said two porcelain ceramic material sheets 2, 3 have the same size and shape as the transparent material sheet 4.

[0014] The porcelain ceramic material sheet 2 is glued over a front face of the transparent material sheet 4, while the other porcelain ceramic material sheet 3 is glued over a rear face of the transparent material sheet 4.

[0015] The porcelain ceramic material sheet 2 has a plurality of through holes 20 identical and coinciding with a plurality of through holes 30 in the other porcelain ceramic material sheet 3, said through holes 20 and 30 being dimensioned so as to advantageously allow to see through the multilayer sheet 1 and to advantageously allow the light to pass through the multilayer sheet 1 without being filtered.

[0016] Preferably, said transparent material sheet 4 is made of transparent glass or a transparent plastic material which allows to ensure the insulation of the wall.

[0017] The porcelain ceramic material sheets 2, 3 are preferably made of porcelain stoneware by means of a known process of sintering ceramic clays, feldspats, kaolins and sand. Alternatively, the use of other stone materials is possible.

[0018] Sheets 2, 3 may also be made of a different opaque material, e.g. of metal or plastic.

[0019] A multilayer sheet 1 is manufactured by enclosing a transparent material sheet 4 between two porcelain ceramic material sheets 2, 3 which are glued thereto on both faces. Known glues are applied to both inner faces of the two porcelain ceramic material sheets 2, 3 for adhering to the front face and to the rear face of the transparent material sheet 4, respectively.

[0020] The two porcelain ceramic material sheets 2, 3 are made directly with a plurality of through holes 20, 30 by means of a cutting or pressing process.

[0021] A plurality of spatial arrangements of through holes 20, 30 of the two porcelain ceramic material sheets 2, 3 may be provided as shown in a first example of multilayer sheet 1 (Figures 1-3) and in a second example of alternative multilayer sheet 1b (Figures 4-6).

[0022] A plurality of said multilayer sheets 1, 1b may be mounted together to build a wall (not shown in the figures) that is advantageously robust, with excellent properties of thermal and acoustic insulation, bright and which allows vision therethrough. The mounting operation may be carried out by placing the multilayer sheets close to one another in the vertical direction or in the horizontal direction, for example for ceilings.

[0023] Alternatively, the multilayer sheets 1, 1b may consist of walls of furniture (not shown in the figures).

[0024] The thus built wall with one or more multilayer sheets 1 advantageously allows vision therethrough, letting the light pass without filters, while preserving excellent properties of thermal and acoustic insulation.

[0025] As shown in Figures 7 and 8, the multilayer sheet 1 (or 1b) may be associated with a sheet of glass or other transparent material 50, for example a glass sheet outside a building, such as a skyscraper, thus forming a wall 60.

[0026] Said sheets 1 and 50 are joined together by means of a joint 51 which allows to leave a chamber 52 closed between said sheets 1 and 50, which is filled with inert gas or contains vacuum.

[0027] Said sheets 1, 50 are glued to said joint 51 for example in the form of a square or rectangular frame following the edge of the sheets 1, 50.

[0028] Alternatively (Figure 9), a wall 60 may be made in accordance with the invention with a multilayer sheet 70 consisting of a transparent material sheet 4 associated with a single opaque material sheet 2, for example made of porcelain ceramic. In said configuration, the transparent material sheet 4 contacts joint 51, for example being glued thereto.

[0029] The embodiment shown in Figure 9 allows saving material while preserving an excellent insulating capability. The passage of light does not change due to the presence of the through holes of sheet 2.

[0030] All the embodiments described advantageously allow an appropriate amount of light to pass and penetrate the glass sheet 50, thus preserving the insulating capability of wall 60, which is important in places with very high external temperatures where energy issues arise when constructing glass buildings such as skyscrapers.

[0031] The present invention thus allows creating well-insulated glass buildings in very warm places. The mounting operation is simple and quick.

[0032] The wall 60 object of the present invention may also be for internal use.
