Description
Brick with intrinsic heat-insulation properties.
The present patent application relates to a brick provided with intrinsic heat-insulation properties..
As it is known, the construction of walls or partitions capable of providing heat insulation to rooms or buildings has become quite popular. To that end, the most popular solution is to create a space inside a brick wall to insert panels made of heat-insulating material.
It must be said that panels of this type usually have a much lower thickness than the space designed to receive them, in order to generate a double air chamber (on the back and on the front of each panel) inside the space in order to additionally reduce the passage of heat and cold through the brick wall.
A similar technology has proved rather effective and has consequently achieved large diffusion, in spite of the fact that its practical application is difficult and expensive. Difficulties and costs are due to the fact that the said space must be provided in the brick walls and heat-insulating panels must be provided and installed in the space of the wall.
A careful examination of the state of the art has resulted in the present invention, whose specific purpose is to provide an easy, inexpensive way to insulate buildings.
The present invention is based on a brick designed to be normally used to build walls, partitions and ceilings, characterised in that it is provided with alveolar structure and includes one or more heat-insulating inserts having the same surface as its lateral sides. More precisely, the inserts are embedded in the material used to manufacture the bricks (either clay or concrete) during the normal moulding by means of suitable dies.
Moreover, it must be noted that the new brick of the invention may be
given the traditional parallelepiped shape of ordinary bricks or, alternatively, an L shape to obtain the angles of the structures to be built, as well as any other regular or irregular shape.
For clarity purposes, the description of the invention continues with reference to the enclosed drawings, which only have an illustrative, not limiting purpose, wherein:
- fig. 1 is a plan view of a clay parallelepiped version of the brick of the invention;
- fig. 2 is a plan view of a concrete parallelepiped version of the brick of the invention;
- fig. 3 is a plan view of a clay angular version of the brick of the invention;
- fig. 4 is a plan view of an indoor version of the brick of the invention of fig. 1.
With reference to fig. 1 , the brick of the invention (1 ), which is provided with basically parallepiped shape and alveolar structure (of the type used in ordinary "perforated bricks"), is characterised in that it embeds a first longitudinal insert (2), consisting in a mat made of sheep's wool or other equivalent materials, provided with heat-insulating and soundproof properties, as well as a second insert (3) parallel to the first insert (2), made of the heat- insulating and heat-reflecting material known as "Pluriball", which is composed of two aluminium sheets (3a) with an intermediate alveolar polyethylene layer (3b).
In particular, the inserts (2, 3) are housed inside corresponding spaces (20, 30) provided inside the brick (1 ) having a considerably larger width, in such a way that a small chamber for heat insulation purposes is originated on each side of the inserts (2, 3).
As shown in fig. 1 , each end of the two inserts (2, 3) is inserted and fixed inside a suitable groove (21 , 31 ) defined by pair of edges (21 a, 31 a) that protrude inwards on the brick of the invention (1 ).
As mentioned earlier, the inserts (2, 3) have basically the same shape and surface as the two lateral sides of the brick (1 ), that is to say the sides designed to be positioned towards the inside and outside of the room to be built.
A similar brick (1 ) is designed to be used to build the external walls of a building, in such a way that the sheep's wool insert (2) faces the inside of the building and the insert (3) with composite structure faces the outside of the building. The sheep's wool insert (2) is specifically designed to reduce the passage of cold from outside inside and the passage of heat from inside outside.
The insert of composite material (3) is specifically designed to reduce the passage of heat from outside inside due to the reflecting action exerted by the external aluminium coating (3a).
The heat-reflecting property of the composite layer (3) is especially advantageous in summer months, when the external temperature is considerably higher that the internal temperature, while the effect of heat barrier exerted by the sheep's wool layer (3) is especially useful in winter months, in order to prevent the heat produced inside the room from being dispersed outside.
Another characteristic of the brick (1 ) of fig. 1 consists in the fact that it is provided with a special alveolar structure in which the cells (4) are situated on staggered adjacent rows; more precisely, the staggered rows are the rows of cells in internal position with respect to first insert (2) of sheep's wool.
The stagger is designed to avoid the perfect alignment of the partitions (4a) of the adjacent rows of cells (4) and consequently the formation of direct heat bridges that could increment the dispersion of heat by conduction from inside outside of the space created with similar bricks. Finally, the brick of the invention (1 ) is normally able to be coupled with similar adjacent bricks by means of male-female coupling.
To that end, the brick (1 ) is provided with a central appendix (5) on one of the transversal sides and a corresponding seat (6) on the opposite side; in this way, the appendix (5) of the brick (1 ) is exactly coupled with the corresponding seat (6) of an identical adjacent brick.
Figure 2 illustrates the same brick (1 ) made of concrete, instead of clay.

Figure 3 illustrates a clay brick (10) that has the same structural configuration as the brick of figure 1 , with a different shape.
In fact, it has an alveolar structure and includes the two heat-insulating inserts (2, 3), made of sheep's wool and of heat-insulating heat-reflecting composite material known as "Pluriball", respectively; moreover, it has the aforementioned staggered alveolar structure.
The L shape, instead of parallelepiped shape, is justified with the intention to use the brick to build angular structures.
Moreover, in view of its angular shape, this version of the brick of the invention (100) is provided with the appendix (50) and corresponding seat (60) on two consecutive sides.
Figure 4 illustrates the version of the brick of the invention (100) designed to built internal walls, or partitions.
In such a context, it is not necessary for a similar brick (100) to screen the heat coming from outside the building, possibly due to solar radiation.
For this reason, it only includes the sheep's wool insert (2) and does not include the heat-reflecting insert made of "Pluriball" composite material.
Evidently, the indoor version of the brick of invention may be easily given the L shape, regardless of the fact that this version is not expressly shown in the enclosed figures.
